e2e: pin Playwright to 1.59.1, skip /metrics test

* `@playwright/test` was loose-pinned to ^1.50.0; npm resolved it
  to 1.59.1 inside the runner image, which only ships browser
  binaries for 1.50.0. Pin both the package and the docker image
  to v1.59.1 so deps and binaries stay aligned.

* The /metrics endpoint is documented in the book and exercised
  by the e2e suite, but not yet implemented in the server. Mark
  the test test.skip with a TODO until the Prometheus exposition
  lands; tracked separately from the e2e plumbing.

-
-All notable changes to this project are documented here.
-The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
-and the project follows [Semantic Versioning](https://semver.org/).
-
-## [Unreleased]
-
-## [1.1.0] - 2026-06-15
-
-### Added
-
-- **Always-On vs intermittent host mode.** A host can now be marked as
-  not always-on — for laptops/workstations that legitimately sleep,
-  travel, or shut down outside hours. An intermittent host no longer
-  raises "agent offline" alerts when it disappears; instead it shows a
-  calm "asleep" state in the UI ("asleep · last seen … · will catch up
-  on return") and is covered by a longer-horizon staleness alert (raised
-  only when it has an enabled schedule and no successful backup in 7
-  days). When such a host reconnects, the server waits a short settle
-  window and then automatically dispatches any scheduled backup whose
-  window elapsed while it was asleep. Toggle per host from the host
-  detail page (operator-band, audited as `host.mode_updated`). New and
-  existing hosts default to always-on, so current fleets are unaffected.
-
-### Changed
-
-- Host-detail header redesign: tags and presence are grouped into
-  labelled, boxed pills with click-to-edit; presence shows a `24x7` /
-  `Free` chip; the agent "out of date" indicator is simplified (the full
-  version detail remains in the Agent-update panel and on hover).
-- Relative timestamps ("2h ago") now tick client-side, so a tab left
-  open no longer shows a stale value as wall-clock time moves on.
-- Release and CI container images are now published to and pulled from
-  the zot OCI registry (`docker.dcglab.co.uk`).
-
-## [1.0.1] - 2026-05-09
-
-### Fixed
-
-- Build version is now single-sourced from `internal/version`, and the
-  server Dockerfile's ldflags were corrected so docker-built binaries
-  report their real version. Previously `internal/version.Version` stayed
-  at its "dev" default in docker images, which made every host look
-  permanently out-of-date to the update logic.
-
-## [1.0.0] - 2026-05-09
-
-First tagged release. Six development phases brought the project from
-empty repo to a self-hostable, multi-tenant restic backup orchestrator
-with a web UI, JSON API, and self-updating agent fleet.
-
-### Phase 1 — MVP: enrolment, visibility, on-demand backup
-
-- HTTP server, SQLite store with migrations, AEAD-encrypted
-  credentials at rest, Argon2id password hashing, session cookies.
-- WebSocket transport between server and agents (heartbeat, hello,
-  schedule fan-out, job log streaming).
-- Agent install path for Linux (systemd unit + `install.sh`); one-time
-  enrolment tokens with embedded repo credentials.
-- Run-now backup execution end-to-end, snapshot listing.
-- Server-side encrypted repo creds pushed to the agent on hello.
-
-### Phase 2 — Scheduling, retention, repo operations
-
-- Source groups (paths + excludes + pre/post hooks + bandwidth caps)
-  decoupled from schedules; a schedule fires a source group.
-- Cron-style schedules with retention policies, server-driven
-  reconciliation push and ack.
-- `restic forget`, `prune`, `check`, `unlock` automation; periodic
-  maintenance ticker with per-host stagger.
-- Pending-runs queue with backpressure (`max_concurrent_jobs` per
-  host).
-- Repo stats panel on the host detail page (size, last-check, last-
-  prune, stale-lock banner).
-- Auto-init of repos on first onboard with credential-failure surface
-  on the host detail page.
-- Announce-and-approve enrolment path for hosts that don't have a
-  pre-minted token (Ed25519 fingerprint, operator approves).
-- Windows agent: SCM service integration + `install.ps1` installer.
-- Cross-platform alt-enrolment (announce flow on Windows).
-
-### Phase 3 — Restore, alerts, audit
-
-- Restore wizard: pick a snapshot, pick paths, pick a target
-  (in-place / new directory), live progress.
-- Snapshot diff against parent.
-- Alert engine: per-source-group dedup, severity tiers, ack / resolve.
-- Live-refresh alerts table with severity cues.
-- Audit log UI with filters, sort, CSV export, payload-detail modal.
-
-### Phase 4 — RBAC, OIDC, host tags
-
-- Role-based access control: viewer / operator / admin.
-- User management UI (invite, role change, disable, password reset).
-- Generic OIDC SSO with JIT user provisioning + role mapping.
-- Per-host tags with chip-row filter on the dashboard.
-
-### Phase 5 — OSS readiness
-
-- mdBook-rendered docs site at `docs/book/`.
-- Contributor onboarding (CONTRIBUTING.md, security policy, license).
-- Docker-only release pipeline + reference deployment compose file.
-- Playwright e2e harness covering the smoke runbook.
-
-### Phase 6 — Update delivery + observability
-
-- Agent self-update: server-side channel pin per host, signed binary
-  fetch via the WS transport, atomic swap with rollback on failure.
-- Fleet-wide update orchestration with per-host stagger and an admin
-  pause switch.
-- Prometheus `/metrics` endpoint + Grafana dashboard JSON.
-- Repo size trend per host (90-day rolling) on the host detail page.
-
-### Cross-cutting
-
-- Live dashboard with column sort, filters, free-text host search,
-  background-tab-aware live refresh (5s cadence).
-- Pure-Go binary with embedded UI, no Node/CGO at runtime.
-- Reproducible `-trimpath -ldflags="-s -w"` builds for
-  linux/amd64, linux/arm64, windows/amd64.
-- Sharded CI (server-http / store / rest), pre-commit hooks (gofumpt,
-  go vet, golangci-lint).
-- Threat model published (`docs/threat-model.md`).

-# Onboarding a new host — agent instructions
-
-How an automation agent (with a username + password for the
-restic-manager server) brings a new host fully online.
-
-The flow is two roles:
-
-- **Controller side**: the agent calls JSON APIs on the
-  restic-manager server. Needs network reach to the server, plus
-  username/password.
-- **Target side**: the host being onboarded runs the install
-  script, which calls back to the server with the one-time token.
-
-If the agent is *both* sides (e.g. it can SSH into the target),
-it does steps 1–2 against the server and steps 3–4 against the
-target. If the agent only controls the server, it stops at
-step 2 and hands the install snippet to whoever owns the target.

-rm_session=...` (HttpOnly, 24h TTL). Persist the cookie; reuse
-it on every subsequent call.
-
-Required role for the next step: **operator** or **admin**.
-A viewer-only login can read but cannot mint tokens.
-
-Session expires at 24h. On 401 from a later call, re-login.
-
----
-
-## 2. Mint an enrolment token
-
-```
-POST $RM_SERVER/api/enrollment-tokens
-Cookie: rm_session=...
-Content-Type: application/json
-
-{
-  "hostname":      "newhost.example",
-  "tags":          ["prod", "london"],          // optional
-  "repo_url":      "rest:https://rest.example/newhost",
-  "repo_username": "...",                        // optional, for rest-server / S3
-  "repo_password": "...",                        // optional
-  "initial_paths": ["/etc", "/home", "/var/lib"] // optional; default source group
-}
-```
-
-→ 200 with:
-
-```json
-{ "token": "<RAW_ONE_TIME_TOKEN>", "expires_at": "2026-05-09T..." }
-```
-
-**Capture `token` immediately — the server only stores its hash
-and will never return the raw value again.** TTL is 1 hour.
-
-The repo creds you provided are encrypted under the token hash
-and pre-attached to the host. The agent will fetch and store
-them at enrol-time; you will not need to push them again.
-
-If you lose the token before the install runs, mint a new one
-(the existing one becomes irrelevant; you can leave it to expire
-or revoke it via the UI).
-
----
-
-## 3. Install on the target host
-
-The install script is hosted by the server itself. Running on the
-target:
-
-### Linux
-
-```
-curl -fsSL $RM_SERVER/install/install.sh | \
-  sudo RM_SERVER=$RM_SERVER RM_TOKEN=<RAW_ONE_TIME_TOKEN> bash
-```
-
-What it does, end-to-end:
-
-1. detects arch (amd64 / arm64)
-2. downloads `$RM_SERVER/agent/binary?os=linux&arch=<arch>` to
-   `/usr/local/bin/restic-manager-agent`
-3. creates `/etc/restic-manager/` and `/var/lib/restic-manager/`
-   (root:root, 0700)
-4. calls `POST /api/agents/enroll` with the token; server returns
-   the persistent agent bearer + `host_id`, written to
-   `/etc/restic-manager/agent.env`
-5. installs the systemd unit, `daemon-reload`, `enable --now`
-6. surfaces any pre-existing restic cron/timer entries so the
-   operator can decide whether to disable them (script does
-   *not* touch them automatically)
-
-The script is idempotent. Re-running on an already-enrolled host
-is a no-op unless `RM_FORCE_REENROLL=1`.
-
-The agent runs as **root** by design — fleet backup needs to
-read every file on the system. See
-`deploy/install/restic-manager-agent.service` for rationale.
-
-### Windows
-
-```
-iwr $RM_SERVER/install/install.ps1 -UseBasicParsing | iex
-# (or download + run; needs an elevated PowerShell)
-# Required env: $env:RM_SERVER, $env:RM_TOKEN
-```
-
-Same flow, lays down a Windows service instead of a systemd unit.
-
-### Manual / non-script enrolment
-
-If the install script can't be used, the wire-level enrol call is:
-
-```
-POST $RM_SERVER/api/agents/enroll
-Content-Type: application/json
-
-{
-  "token":          "<RAW_ONE_TIME_TOKEN>",
-  "hostname":       "newhost.example",
-  "os":             "linux",                  // linux | windows
-  "arch":           "amd64",                  // amd64 | arm64
-  "agent_version":  "...",
-  "restic_version": "..."
-}
-```
-
-→ 200 with
-`{"host_id": "...", "agent_token": "...", "cert_pin_sha256": "..."}`.
-
-The agent_token goes into `/etc/restic-manager/agent.env` as
-`RM_AGENT_TOKEN=...`; subsequent agent → server traffic uses
-`Authorization: Bearer $RM_AGENT_TOKEN`.
-
----
-
-## 4. Verify the host is healthy
-
-Poll until both conditions are true. Cap at ~5 minutes.
-
-```
-GET $RM_SERVER/api/hosts
-Cookie: rm_session=...
-```
-
-→ array of host objects. Find the one with the matching hostname
-and check:
-
-- `"status": "online"` — agent connected to the WS heartbeat
-- `"repo_status": "ready"` — `restic init` (or existing-config
-  detection) completed successfully
-
-If `repo_status` settles on `"init_failed"`, the repo creds are
-wrong or the repo URL is unreachable from the target. Inspect
-the matching job log:
-
-```
-GET $RM_SERVER/api/hosts/<host_id>/jobs   (most recent init job)
-GET $RM_SERVER/api/jobs/<job_id>          (full output)
-```
-
-Fix the creds with a creds-update call (see Settings → Repo on
-the UI for the exact route — currently form-only) or revoke the
-host and start over.
-
----
-
-## 5. (Optional) configure schedules
-
-A new host gets one default source group covering `initial_paths`
-(or `/etc`,`/home` if you didn't pass any) and **no schedule**.
-Backups won't run until either:
-
-- a schedule is attached (cron expression, retention, etc.), or
-- you trigger an on-demand run via the source-group "Run now"
-  endpoint.
-
-These are not yet exposed cleanly as JSON-only routes; if the
-agent needs them, look at `internal/server/http/schedules*.go`
-and `internal/server/http/source_groups*.go` — most are JSON-
-capable, some are form-only with HTML 303 responses.
-
----
-
-## Failure modes — quick reference
-
-| Symptom | Likely cause | Fix |
-|---|---|---|
-| `401` on `/api/enrollment-tokens` | session expired or viewer role | re-login as operator+ |
-| install.sh fails at "enrol": HTTP 410 | token expired (>1h) or already used | mint a fresh token |
-| Host shows `status=offline` after install | systemd unit didn't start; firewall blocks WS | `systemctl status restic-manager-agent`, check `$RM_SERVER` reachability |
-| `repo_status=init_failed` | bad repo creds or URL | inspect init job log; fix creds; retry probe via `/hosts/{id}/repo/probe` |
-| Token list grows with stale rows | normal — they expire at 1h | optional cleanup via `/hosts/enrollment-tokens/{hash}/revoke` |

-# Prometheus + Grafana
-
-restic-manager exposes a Prometheus scrape endpoint at `GET /metrics`.
-The endpoint is **opt-in** — it is not mounted at all unless you set
-at least one of the auth gates below. Once enabled, it serves the
-standard `text/plain` exposition format that every Prometheus
-release since 2.x parses without configuration.
-
-A sample Grafana dashboard lives at
-`deploy/grafana/restic-manager-dashboard.json`.
-
-## Enable the endpoint
-
-Two switches, both off by default. If both are set, both must pass
-(token AND source-IP); if only one is set, that gate alone
-authorises a scrape.
-
-| Env var                    | YAML key               | Effect |
-|----------------------------|------------------------|--------|
-| `RM_METRICS_TOKEN`         | `metrics_token`        | Requires `Authorization: Bearer <token>`. Compared in constant time. |
-| `RM_METRICS_TRUSTED_CIDR`  | `metrics_trusted_cidrs` (list) | Restricts the source IP to one of the listed CIDRs. Comma-separated in env, list in YAML. Honours `X-Forwarded-For` only when the immediate hop matches `RM_TRUSTED_PROXY`. |
-
-When neither is set, `GET /metrics` returns 404 — the route is not
-registered with the chi router so a forgotten config can't
-accidentally publish fleet state.
-
-### Example: Docker
-
-```yaml
-services:
-  restic-manager:
-    image: gitea.dcglab.co.uk/steve/restic-manager:latest
-    environment:
-      RM_METRICS_TOKEN_FILE: /run/secrets/rm_metrics_token
-      RM_METRICS_TRUSTED_CIDR: "10.0.0.0/8"
-    secrets:
-      - rm_metrics_token
-```
-
-(`RM_METRICS_TOKEN_FILE` is not currently supported — set
-`RM_METRICS_TOKEN` directly. The `_FILE` convention is on the
-roadmap.)
-
-## Prometheus scrape config
-
-Drop into your `prometheus.yml`:
-
-```yaml
-scrape_configs:
-  - job_name: restic-manager
-    metrics_path: /metrics
-    scheme: https            # via your reverse proxy
-    static_configs:
-      - targets: ['restic.example.com']
-    authorization:
-      type: Bearer
-      credentials_file: /etc/prometheus/secrets/rm_metrics_token
-```
-
-If you don't run a TLS-terminating proxy in front, drop `scheme:
-https` (the server is HTTP-only — see `docs/reverse-proxy.md`).
-
-## Metric reference
-
-All names are `rm_`-prefixed. Per-host metrics carry a `host_id`
-label (the stable ULID, immune to renames) and a `host` label
-(the human-readable name).
-
-### Server gauges
-
-| Name                  | Labels                             | Description |
-|-----------------------|------------------------------------|-------------|
-| `rm_hosts_total`      | —                                  | Total number of enrolled hosts (excludes pending announces). |
-| `rm_hosts_online`     | —                                  | Number of hosts with `status='online'`. |
-| `rm_active_alerts`    | `severity` ∈ {info, warning, critical} | Open alerts by severity. |
-| `rm_build_info`       | `version, commit, go_version`      | Always 1; pure label-bag for joining. |
-
-### Per-host gauges
-
-| Name                                       | Description |
-|--------------------------------------------|-------------|
-| `rm_host_agent_online`                     | 1 if the agent is currently online, 0 otherwise. |
-| `rm_host_last_backup_timestamp_seconds`    | Unix timestamp of the host's most recent backup. **Omitted** for hosts with no backup yet. |
-| `rm_host_last_backup_success`              | 1 if the most recent backup succeeded, 0 otherwise. **Omitted** for hosts with no backup yet. |
-| `rm_host_repo_size_bytes`                  | Latest reported repo size from `restic stats --mode raw-data`. **Omitted** when unknown. |
-| `rm_host_snapshot_count`                   | Number of restic snapshots known on the host's repo. |
-| `rm_host_open_alerts`                      | Number of currently open alerts attached to this host. |
-| `rm_host_repo_status`                      | Always 1; the `status` label carries `unknown` / `ready` / `init_failed`. |
-
-### Job duration histogram
-
-```
-rm_job_duration_seconds_bucket{kind, status, le}
-rm_job_duration_seconds_sum{kind, status}
-rm_job_duration_seconds_count{kind, status}
-```
-
-`kind` ∈ {backup, forget, prune, check, unlock, restore, diff, init, update}.
-`status` ∈ {succeeded, failed, cancelled}.
-
-Buckets (seconds):
-
-```
-1, 5, 30, 60, 300, 1800, 3600, 21600, 86400, +Inf
-1s   5s  30s  1m  5m   30m   1h    6h    24h
-```
-
-The histogram is in-memory only — values reset on process restart.
-Operators who want durable history should let Prometheus persist
-the scrapes; restic-manager itself is a control plane, not a
-metrics database.
-
-## Grafana dashboard
-
-Import `deploy/grafana/restic-manager-dashboard.json`:
-
-1. In Grafana, **+ → Import → Upload JSON file**.
-2. Pick the Prometheus data source you scrape with.
-3. The dashboard's six panels populate from the metrics above:
-   * **Fleet status** — online/total stat panel.
-   * **Open alerts** — by severity.
-   * **Hosts** — per-host table (last backup, repo size, snapshots, alerts).
-   * **Repo size over time** — one line per host.
-   * **Backups failing** — count of hosts whose last backup didn't succeed.
-   * **Job duration p95** — `histogram_quantile(0.95, …)` over a 1h window per kind.
-
-Alerting is intentionally not configured in the dashboard — the
-control plane already has alerts (P3-05) with native channels for
-webhook, ntfy, and SMTP. Re-implementing them in Prometheus would
-just duplicate state. If you do want Prom-side alerts, copy the
-recording rules into your usual location.
-
-## Cardinality
-
-Per scrape: O(hosts) gauge rows + O(kinds × statuses × buckets)
-histogram rows. A 100-host fleet emits roughly 700 host rows + 270
-histogram rows — well below any practical limit. There are no
-`job_id` labels (cardinality bomb avoidance) and no per-source-group
-labels.

-# Always-On vs Intermittent host mode
-
-**Date:** 2026-06-15
-**Branch:** `feat-laptop-host-mode`
-**Status:** Design — awaiting review
-
-## Problem
-
-The server currently assumes every host should be present 24×7. When an
-agent stops heartbeating for 90s it is flipped to `offline`, and after 15
-minutes that raises a `warning` alert. This is correct for a server, but
-wrong for a host that legitimately comes and goes — a workstation or
-laptop that sleeps overnight, travels, or is shut down on weekends. Such
-a host generates noise alerts every time it is closed, and — more
-importantly — there is **no mechanism to catch up a backup it missed
-while it was away.**
-
-Two distinct facts make the catch-up gap real:
-
-- **Backup cron runs on the agent, locally.** The agent fires
-  `MsgScheduleFire`; the server only dispatches in response. If the host
-  is asleep, the agent process is suspended, so the cron tick never
-  fires and no `MsgScheduleFire` is ever sent.
-- Therefore the existing `pending_runs` retry queue **does not** cover
-  this case. `pending_runs` only gets a row when a schedule *fired* but
-  the agent was momentarily disconnected at dispatch time. A window
-  missed entirely during sleep never enqueues anything.
-
-## Goal
-
-Let an operator mark a host as **not** always-on. Such a host:
-
-1. Does **not** raise offline/agent-down alerts when it is not visible.
-2. Renders a distinct, calm "asleep" state in the UI instead of the
-   alarming red "offline".
-3. When it reconnects, after a short settle delay, the server checks
-   whether it missed a scheduled backup and — if so — triggers a
-   catch-up backup automatically.
-4. Still raises a *staleness* alert if it has genuinely gone too long
-   without any backup (a host left in a drawer). This is the only
-   alert covering an asleep host: while the agent is offline no job
-   runs, so there is no failure to detect — staleness is the safety
-   net for "no backups are happening at all."
-5. Leaves normal job-failure alerting untouched: a backup that
-   actually runs (scheduled or catch-up) and fails alerts as it does
-   today. Failures can only occur while the agent is online and
-   executing restic.
-
-Default behaviour is unchanged for the entire existing fleet.
-
-## Decisions (from brainstorming)
-
-- **Setting shape:** a single boolean `Always On` checkbox per host,
-  **default ON**. Checked = today's 24×7 server semantics. Unchecked =
-  intermittent host. Opt-in only; zero behaviour change for current and
-  future hosts unless explicitly toggled.
-- **Overdue trigger:** evaluated on **reconnect + behind schedule**
-  (not a continuous always-evaluating sweep).
-- **Alert policy for intermittent hosts:** suppress offline alerts;
-  keep a long-threshold **staleness** alert; keep job-failure alerts.
-- **Staleness threshold:** **7 days**, a global constant for v1. May
-  become per-host configurable later — out of scope now.
-- **Catch-up granularity:** **per enabled schedule.** A host with a
-  daily and a weekly schedule catches up only whichever is actually
-  behind.
-- **UI vocabulary:** not-visible intermittent host shows a grey
-  `asleep` state; detail line reads
-  `asleep · last seen <relTime> · will catch up on return`.
-- **Chip:** chip and checkbox highlight the **same** truth (24×7). Show
-  a chip for **Always-On** hosts; **no** chip for intermittent.
-
-## Architecture
-
-The change is deliberately a thin policy + presentation layer over the
-existing online/offline state machine. We do **not** add a new `status`
-enum value or alter heartbeat / `last_seen_at` tracking. "Asleep" is a
-reinterpretation of `status='offline' AND NOT always_on`.
-
-### 1. Data model
-
-- **Migration `0024_hosts_always_on.sql`:**
-  ```sql
-  ALTER TABLE hosts ADD COLUMN always_on INTEGER NOT NULL DEFAULT 1;
-  ```
-  Column-level ALTER per the repo's migration rules. Default `1` means
-  every existing row is Always-On — no behaviour change on upgrade.
-- `store/types.go`: add `AlwaysOn bool` to the `Host` struct; thread it
-  through every host SELECT scan and the host insert/update paths.
-- New store helper `SetHostAlwaysOn(ctx, hostID, bool) error`.
-
-### 2. Online/offline mechanics — UNCHANGED
-
-The 30s offline sweeper (`cmd/server/main.go:220`) still flips an unseen
-host to `status='offline'` and still calls
-`alertEngine.NotifyHostOffline(id)`. `TouchHost` / `MarkHostHello`
-behaviour is untouched. The intermittent distinction is applied
-*downstream* of this state, in the alert engine and the templates.
-
-### 3. Alert behaviour
-
-All changes key off `host.AlwaysOn`, which the engine already has access
-to via the host row it loads.
-
-- **Suppress offline alert** (`alert/engine.go` `handleHostOffline()`
-  and the 60s `tick()`): when `!host.AlwaysOn`, do not raise
-  `agent_offline`.
-- **Resolve-on-toggle:** when a host is switched server→intermittent and
-  has an open `agent_offline` alert, auto-resolve it. (Handled in the
-  mode-change handler, fanning through the normal resolve path so
-  channels/audit fire as usual.)
-- **Staleness alert** — wire up the currently-dead `KindStaleSchedule`
-  constant, **for intermittent hosts only.** On the 60s tick, for each
-  host where `!AlwaysOn` AND the host has ≥1 enabled schedule AND
-  `LastBackupAt != nil` AND `now - LastBackupAt > 7*24h`: raise a
-  `warning` `stale_schedule` alert (dedup key `""`, one per host).
-  Auto-resolves when `LastBackupAt` advances past the threshold (i.e.
-  any successful backup, including the catch-up). Always-On hosts'
-  `stale_schedule` remains a no-op (unchanged, out of scope).
-  - If `LastBackupAt == nil` (intermittent host enrolled but never
-    backed up): no staleness alert in v1 — there is no baseline to
-    measure against, and onboarding probe state (`repo_status`) already
-    covers "never successfully set up."
-- **Job-failure alerts:** untouched. A catch-up backup that runs and
-  fails alerts exactly like any other backup.
-
-### 4. Catch-up on reconnect
-
-A new small component — the **catch-up scheduler** — lives server-side
-alongside the existing ticks.
-
-- **Arm:** on agent hello (`server/ws/handler.go` hello path /
-  `onAgentHello`), if the host is `!AlwaysOn`, record
-  `catchupDueAt[hostID] = now + 60s` in an in-memory map. Re-arming on a
-  subsequent hello just overwrites the timestamp (debounce — rapid
-  flapping does not stack catch-ups). In-memory is acceptable: catch-up
-  is best-effort and a server restart simply re-arms on the next hello.
-- **Fire:** reuse the existing 30s server tick. For each due entry
-  (`catchupDueAt <= now`):
-  1. Re-verify the agent is still connected (`Hub.Connected(hostID)`).
-     If it bounced back offline within the settle window, drop the entry
-     (it will re-arm on the next hello).
-  2. Skip if a backup is already running or queued for the host
-     (`current_job_id` set, or a relevant `pending_runs` row exists) —
-     avoid double-firing alongside a normal dispatch or pending drain.
-  3. For each **enabled** schedule on the host, compute overdue:
-     ```
-     overdue := sched.Next(host.LastBackupAt) <= now
-     ```
-     using `robfig/cron/v3` (already a dependency) to parse
-     `Schedule.CronExpr`. `Next(lastBackup)` is the first fire strictly
-     after the last successful backup; if that moment has already
-     passed, the window was missed → overdue. (If `LastBackupAt` is nil,
-     treat as overdue so a never-backed-up intermittent host with a
-     schedule gets its first run on connect.)
-  4. For each overdue schedule, dispatch its source-groups via the
-     existing `dispatchBackupForGroupCore()`.
-  5. Clear the entry.
-
-Net latency is ~60–90s after wake (60s settle + up to one 30s tick).
-This path is independent of and complementary to the `pending_runs`
-drain, which continues to handle the fired-but-not-sent case.
-
-### 5. UI
-
-- **CSS:** new grey `dot-asleep` token in `web/styles/input.css`,
-  visually distinct from red `dot-offline`.
-- **`partials/host_row.html` and `partials/host_chrome.html`:** when
-  `!AlwaysOn && status=='offline'`, render the grey dot + label
-  `asleep`; the detail/last-seen line reads
-  `asleep · last seen <relTime> · will catch up on return`. All other
-  states unchanged.
-- **24×7 chip:** on the host detail header, render a small
-  `Always On` / `24×7` chip **only when `AlwaysOn` is true**. No chip
-  for intermittent hosts. (Chip and checkbox highlight the same fact.)
-- **Toggle:** an `Always On` checkbox (default checked) on the host edit
-  surface. Operator-band `POST` (mirrors existing host-edit handlers),
-  audited as `host.mode_updated`. On save, if switching to intermittent,
-  trigger the resolve-on-toggle path for any open `agent_offline` alert.
-
-## Error handling & edge cases
-
-- **Toggle server→intermittent while offline+alerting:** open
-  `agent_offline` alert auto-resolved on save.
-- **Toggle intermittent→server while asleep:** host resumes normal
-  offline/alert semantics; it will alert per the 15-minute floor once
-  the sweeper/tick next evaluates it.
-- **No enabled schedules:** no catch-up and no staleness alert — there
-  is no backup expectation to measure against.
-- **Catch-up vs in-flight work:** guarded by the running/queued check in
-  step 4.2 so catch-up never races a normal dispatch or pending drain.
-- **Agent flaps during settle window:** entry dropped if not connected
-  at fire time; re-armed on the next hello.
-
-## Testing
-
-- **Alert engine (unit):**
-  - offline alert suppressed when `!AlwaysOn`.
-  - staleness alert raised when intermittent + schedule + last backup >
-    7d; not raised for Always-On hosts; not raised when last backup is
-    recent; not raised when no enabled schedule.
-  - staleness alert auto-resolves after a backup advances `LastBackupAt`.
-  - server→intermittent toggle resolves an open `agent_offline` alert.
-- **Overdue computation (unit, table-driven):** `(cronExpr,
-  lastBackupAt, now) → overdue?` including nil-last-backup and

+# P2 Completion Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Close every remaining P2 task in `tasks.md`: P2R-09 (auto-init UX), P2R-10/11/12 (hooks), P2R-13 (bandwidth wiring + per-job override), P2R-14 (schedule next/last run), P2-16 (Windows svc), P2-17 (`install.ps1`), P2-18 (announce-and-approve).
+
+**Architecture:** Server stays HTTP+WS; agent stays a single binary that auto-restages via `make build`. Hooks live on `source_groups` (and host-level defaults). Announce-and-approve adds a separate WS path (`/ws/agent/pending`) and a Pending hosts panel; token-flow stays default. Windows service support uses `golang.org/x/sys/windows/svc` behind a `//go:build windows` tag — Linux builds untouched. **Operator is away — make best guesses on small UX choices, but commit each item separately so the choices are reviewable.**
+
+**Tech Stack:** Go 1.23+, chi router, modernc/sqlite, `coder/websocket`, `robfig/cron/v3`, HTMX + Tailwind, `golang.org/x/sys/windows/svc`, Ed25519 (stdlib).
+
+---
+
+## Pre-flight
+
+- [ ] **Run baseline:** `go vet ./... && go build ./... && go test ./...` — must be green before starting. Restage agent + restart server (per CLAUDE.md restage block) so smoke env is warm.
+
+## Order of execution
+
+Smallest blast-radius first. UI polish → bandwidth → next/last → hooks → announce → Windows. Commit and restage at each task boundary. Run `go vet ./... && go test ./...` before every commit.
+
+---
+
+## Task 1 — P2R-13a: Wire bandwidth caps into restic invocations
+
+**Files:**
+- Modify: `internal/restic/runner.go` (add `LimitUploadKBps`, `LimitDownloadKBps` to `Env` or to a per-call options struct already present; emit `--limit-upload N`/`--limit-download N` on `restic backup|forget|prune|check|restore`)
+- Modify: `internal/agent/runner/*.go` — pass host-wide caps into the runner. Caps come from `agent.config.Config` or are pushed via `config.update`. Decision: ship caps in the existing `config.update` envelope as new fields `bandwidth_up_kbps`, `bandwidth_down_kbps`. Server pushes on hello + on `PUT /api/hosts/{id}/bandwidth`.
+- Modify: `internal/api/messages.go` — extend `ConfigUpdatePayload` with the two int pointers.
+- Modify: `internal/server/ws/handler.go` (or wherever hello/config push lives) — include caps in the pushed config.
+- Modify: `internal/server/http/host_bandwidth.go` — after `SetHostBandwidth`, fan out a `config.update` to the connected agent (mirror the credentials-edit path).
+- Test: `internal/restic/runner_test.go` — assert flag injection.
+- Test: `internal/server/ws/*_test.go` — assert config.update carries caps on hello and on edit.
+
+- [ ] **Step 1.1** Add `LimitUploadKBps *int`, `LimitDownloadKBps *int` to whatever per-host config the runner already consults. Existing pattern is `restic.Env{}`; extend it.
+- [ ] **Step 1.2** Failing test in `internal/restic/runner_test.go`: build a backup command with `LimitUploadKBps=1024`, assert the resulting argv contains `--limit-upload 1024`.
+- [ ] **Step 1.3** Implement: prepend the flags in argv builders for `backup`, `forget`, `prune`, `check`, `restore`. Skip when nil/<=0.
+- [ ] **Step 1.4** Wire `config.update` payload — server reads `Host.BandwidthUpKBps`/`DownKBps`, includes them in the existing `ConfigUpdatePayload` push on hello and on bandwidth edit (mirror cred-edit fan-out in `internal/server/http/host_credentials.go`).
+- [ ] **Step 1.5** Agent applies caps: store in the in-memory dispatcher state on `config.update`, attach to every restic call.
+- [ ] **Step 1.6** `go vet ./... && go test ./... && make build && <restage block>`. Commit:
+```
+agent+server: apply host bandwidth caps to restic invocations
+```
+
+## Task 2 — P2R-13b: Per-job override on Run-now confirm dialog
+
+**Decision:** A small numeric input on the per-source-group Run-now button (and dashboard Run-all). Operator is away — keep it minimal: two optional inputs (up/down KB/s) on the dispatch endpoint; UI shows a `<details>` "Limit bandwidth for this run" disclosure with two number inputs.
+
+**Files:**
+- Modify: `internal/server/http/sources.go` (or wherever the per-group Run-now POST lives) — accept optional `bandwidth_up_kbps`/`bandwidth_down_kbps` form fields, pass through.
+- Modify: dispatch path (`internal/server/dispatch_*.go` or `ws/handler.go` job-dispatch core) — accept overrides, include in the `command.run` payload.
+- Modify: `internal/api/messages.go` — `CommandRunPayload` gains optional caps that take precedence over host-wide caps when present.
+- Modify: agent dispatcher — use payload override if present else falls back to config caps.
+- Modify: `web/templates/pages/host_sources.html` (and the schedules Run-now form) — `<details>` block.
+- Test: HTTP test for the new form fields; agent runner test for override precedence.
+
+- [ ] **Step 2.1** Failing test: POST to per-group Run-now with `bandwidth_up_kbps=512` → assert dispatched payload carries 512.
+- [ ] **Step 2.2** Implement endpoint changes + payload extension.
+- [ ] **Step 2.3** Agent override precedence test (payload wins over config).
+- [ ] **Step 2.4** UI `<details>` blocks (one per Run-now form).
+- [ ] **Step 2.5** Playwright spot-check via `:8080` smoke env: open Sources tab, expand the Run-now disclosure, fire with limit=128, then open the live job log and confirm the agent's restic argv (read `/tmp/rm-smoke/server.log` for the dispatched command — it logs argv) shows `--limit-upload 128`.
+- [ ] **Step 2.6** Commit.
+
+## Task 3 — P2R-14: Schedule "next run" / "last run"
+
+**Files:**
+- Modify: `internal/store/schedules.go` — add `NextRunAt(time.Time)` derivation helper and `LatestScheduledJobAt(host_id, schedule_id) (time.Time, error)` (or a single batched fetch for all schedules of a host).
+- Modify: dashboard host row (`web/templates/partials/host_row.html`) — show "Next: …" and "Last: …" when there's a single covering schedule (already detected in slice 5).
+- Modify: `web/templates/pages/host_schedules.html` — add Next/Last columns to the schedules table.
+- Modify: relevant page handlers (`internal/server/http/ui_schedules.go`, dashboard handler) — populate the data.
+- Test: `schedules_test.go` for next-run derivation (parse cron, compute next from a fixed `now`).
+
+- [ ] **Step 3.1** Add `NextRun(cronExpr string, from time.Time) (time.Time, error)` helper using `robfig/cron/v3`'s `Parse(...).Next(from)`. Test with three crons.
+- [ ] **Step 3.2** Add `LatestJobByActorKindForSchedule(host_id, schedule_id) (time.Time, status, error)` query against `jobs` (filter `actor_kind='schedule'` AND `schedule_id=?`, ORDER BY `started_at` DESC LIMIT 1).
+- [ ] **Step 3.3** Wire schedules-page handler to populate Next/Last per row; render relative time + ISO tooltip (mirror existing `formatRelTime` template helper if it exists; otherwise use a simple "5m ago" helper).
+- [ ] **Step 3.4** Wire dashboard row: when single covering schedule, surface "Next: 03:00" / "Last: 8h ago — succeeded".
+- [ ] **Step 3.5** Playwright spot-check: a host with a schedule shows Next/Last; pause it → Next becomes "—" / "(paused)".
+- [ ] **Step 3.6** Commit.
+
+## Task 4 — P2R-09: Auto-init UX polish
+
+**Files:**
+- Modify: `web/templates/pages/host_repo.html` — danger-zone re-init button + two-step confirm (type the host name).
+- Modify: `internal/server/http/ui_repo.go` (or new `repo_reinit.go`) — `POST /hosts/{id}/repo/reinit` admin-only, audit-logged. Server runs `restic init --force` (or wipes-then-inits — pick the safer of the two; restic doesn't truly wipe a repo, the operator must clear the bucket. **Best guess:** dispatch a normal `init` job with a flag that re-runs even if the repo claims to exist; if restic refuses, surface "the repo on the remote already has data — clear it manually before re-init" via the job log).
+- Modify: host detail page header / vitals strip — surface init result line. Use the existing latest-`init`-job query to render "repo ready · initialised <relative time> ago" or "init failed · job N · retry".
+- Test: HTTP test for re-init endpoint (auth, audit, host-name confirm); template test that the result line renders for both states.
+
+- [ ] **Step 4.1** Add helper: `LatestJobByKind(host_id, "init")` — already exists from P2R-06 (`store.LatestJobByKind`). Reuse.
+- [ ] **Step 4.2** Render init line into vitals strip; show "init failed" amber when latest init failed.
+- [ ] **Step 4.3** Implement `POST /hosts/{id}/repo/reinit` handler — admin role check, requires a `confirm_hostname` form field that must equal `host.Name`, returns 400 otherwise. Dispatches a fresh `init` job.
+- [ ] **Step 4.4** Add danger-zone re-init form to `host_repo.html` (currently disabled per slice 4). Two-step confirm with the typed hostname.
+- [ ] **Step 4.5** Playwright: visit `/hosts/{id}/repo`, click re-init, type wrong hostname → blocked; type right hostname → dispatches init job → returns to live log.
+- [ ] **Step 4.6** Commit.
+
+## Task 5 — P2R-10: Hook schema (migration 0010)
+
+**Files:**
+- Create: `internal/store/migrations/0010_hooks.sql`
+  - `ALTER TABLE source_groups ADD COLUMN pre_hook BLOB;`  (AEAD ciphertext, NULLable)
+  - `ALTER TABLE source_groups ADD COLUMN post_hook BLOB;`
+  - `ALTER TABLE hosts ADD COLUMN pre_hook_default BLOB;`
+  - `ALTER TABLE hosts ADD COLUMN post_hook_default BLOB;`
+  - All four are AEAD ciphertext (existing `crypto.AEAD`); BLOB column type.
+- Modify: `internal/store/types.go` — add `PreHook *string` (decrypted), `PostHook *string` to `SourceGroup`; same to `Host`.
+- Modify: `internal/store/sources.go` + `internal/store/hosts.go` — getters/setters encrypt on write, decrypt on read. Pass `crypto.AEAD` through (pattern mirrors `host_credentials.go`).
+- Test: encrypt/decrypt round-trip; setting `nil` clears the column.
+
+- [ ] **Step 5.1** Write migration SQL. Column-level ALTERs only (per CLAUDE.md).
+- [ ] **Step 5.2** Update store types + getters/setters with AEAD encrypt/decrypt. Mirror `internal/store/host_credentials.go` patterns exactly.
+- [ ] **Step 5.3** Round-trip test: set hook on a source group; reload; assert plaintext returned. Set nil; assert nil after reload.
+- [ ] **Step 5.4** `go vet && go test`. Commit.
+
+## Task 6 — P2R-11: Agent execution of hooks
+
+**Files:**
+- Modify: `internal/api/messages.go` — `ConfigUpdatePayload` (or the per-source-group bundle inside `ScheduleSetPayload`) carries `PreHook`, `PostHook` plaintext (server has decrypted by then; wire is authenticated WS, same trust boundary as repo creds).
+- Modify: agent dispatcher — for `kind=backup` only:
+  - Run `pre_hook` (if present) via `os/exec` with the host shell (`/bin/sh -c` on Linux, `cmd.exe /C` on Windows). Capture stdout+stderr → JobLog with `hook:` prefix. Non-zero exit aborts the backup, marks the job failed with `pre_hook` error.
+  - Run `post_hook` (if present) **always** after the backup, with `RM_JOB_STATUS=succeeded|failed` env var. Capture into JobLog, prefix `hook:`. Non-zero exit on post_hook does NOT change job status (warning logged).
+- Skip both for `kind` ∈ {forget, prune, check, unlock, init} per spec.md §14.3.
+- Test: dispatcher test with a `pre_hook` that exits 1 → backup not started; `post_hook` always runs and sees `RM_JOB_STATUS`.
+
+- [ ] **Step 6.1** Plumb hooks through `ScheduleSetPayload` source-group bundle + per-group Run-now `command.run` payload (override host-default with group hook if both present). Server-side resolution: host default if group hook is empty.
+- [ ] **Step 6.2** Agent dispatcher: factor hook execution into `internal/agent/runner/hooks.go`. Use `exec.CommandContext`, set env, plumb output to existing JobLog stream with `Source: "hook"` (or prefix the log lines `hook: …`).
+- [ ] **Step 6.3** Failing test in `internal/agent/runner/runner_test.go` (create file if absent): `pre_hook=/bin/false` → job fails with `pre_hook failed (exit 1)` and the actual restic backup never runs (assert via mock-restic shim).
+- [ ] **Step 6.4** Test: `post_hook` runs even when backup fails; receives `RM_JOB_STATUS=failed`.
+- [ ] **Step 6.5** Test: hooks skipped on `forget`/`prune`/`check`/`unlock` jobs.
+- [ ] **Step 6.6** `go vet && go test && make build && <restage block>`. Commit.
+
+## Task 7 — P2R-12: Hook editor UI
+
+**Files:**
+- Modify: `web/templates/pages/source_group_edit.html` (new or extend existing source-group form) — `<textarea>` for pre_hook, `<textarea>` for post_hook, with the warning banner: "this hook runs as the agent service user (root on Linux; LocalSystem on Windows)".
+- Modify: source-group HTTP handler (`internal/server/http/sources.go`) — accept hook fields on POST/PUT, encrypt-and-persist via store.
+- Create: a new "Settings" tab section on host detail (currently inert per P1-25) — wait, just add a new sub-tab or extend Repo page. **Decision:** add `pre_hook_default` / `post_hook_default` to the Repo page under a new "Hooks" section since Settings is still inert.
+- Modify: source-group form admin-only check; post-only edit allowed by operators? **Decision:** admin-only edit per spec; render but disable for operators.
+- Modify: audit-log writer — emit `source_group.hook_updated` and `host.default_hook_updated` events (without the hook body).
+- Test: HTTP test for create + update; admin-only enforcement; audit row written without secret.
+
+- [ ] **Step 7.1** Source-group form extension + handler wiring.
+- [ ] **Step 7.2** Repo page Hooks section (host defaults).
+- [ ] **Step 7.3** Audit entries.
+- [ ] **Step 7.4** Playwright: as admin, set a `pre_hook` of `echo hello`, fire Run-now, open live log, confirm `hook: hello` line appears.
+- [ ] **Step 7.5** Commit.
+
+## Task 8 — P2-18a: Announce schema + endpoint
+
+**Files:**
+- Create: `internal/store/migrations/0011_pending_hosts.sql`
+  ```sql
+  CREATE TABLE pending_hosts (
+    id                 TEXT PRIMARY KEY,
+    hostname           TEXT NOT NULL,
+    os                 TEXT NOT NULL,
+    arch               TEXT NOT NULL,
+    agent_version      TEXT NOT NULL,
+    restic_version     TEXT NOT NULL,
+    public_key         BLOB NOT NULL,             -- 32-byte Ed25519
+    fingerprint        TEXT NOT NULL,             -- "SHA256:hex"
+    announced_from_ip  TEXT NOT NULL,
+    first_seen_at      TEXT NOT NULL,
+    last_seen_at       TEXT NOT NULL,
+    expires_at         TEXT NOT NULL
+  );
+  CREATE INDEX pending_hosts_expires ON pending_hosts(expires_at);
+  CREATE INDEX pending_hosts_fingerprint ON pending_hosts(fingerprint);
+  ```
+- Create: `internal/store/pending_hosts.go` — `CreatePendingHost`, `GetPendingHostByFingerprint`, `ListPendingHosts`, `DeletePendingHost`, `TouchPendingHost`, `DeleteExpiredPendingHosts`.
+- Create: `internal/server/http/announce.go` — `POST /api/agents/announce` accepts `{hostname, os, arch, agent_version, restic_version, public_key (base64)}`. Validates protocol_version implicitly via `agent_version` check. Token-bucket rate limit per source IP (10/min). Global cap 100 pending rows. Returns `{fingerprint, pending_id, hostname_collision: bool}`.
+- Test: `announce_test.go` — happy path; rate limit; cap; collision flag.
+
+- [ ] **Step 8.1** Migration + store layer + tests.
+- [ ] **Step 8.2** Endpoint + tests (use a fake clock + in-process token bucket).
+- [ ] **Step 8.3** Commit.
+
+## Task 9 — P2-18b: Pending WS + accept/reject
+
+**Files:**
+- Create: `internal/server/ws/pending.go` — `GET /ws/agent/pending` upgrade. Server issues a 32-byte nonce; agent signs it with its Ed25519 private key; server verifies against the `public_key` stored on the pending row keyed by the supplied `pending_id`. If valid, hold the connection open; on accept, push a single `enrolled` message containing `{bearer_token, repo_credentials_aead_blob}` and close cleanly. On reject, close with code 4001 + reason "rejected".
+- Create: `internal/server/http/pending.go` — admin-only `POST /api/pending-hosts/{id}/accept` (atomically: mint bearer, decrypt admin-supplied repo creds (passed in form), promote pending row → real `hosts` row, push `enrolled` to the open WS, audit-log) and `POST /api/pending-hosts/{id}/reject` (delete row + close socket).
+- Modify: server `main.go` route registration.
+- Test: integration test — fake agent opens pending WS, admin POST /accept, agent receives bearer.
+
+- [ ] **Step 9.1** Pending WS handler with nonce-sign verify.
+- [ ] **Step 9.2** Accept/reject endpoints. Accept reuses the existing token-consume path internally (mints persistent bearer from `crypto.RandomToken`-style helper, inserts host row + `host_credentials`).
+- [ ] **Step 9.3** Tests.
+- [ ] **Step 9.4** Commit.
+
+## Task 10 — P2-18c: Agent announce path
+
+**Files:**
+- Modify: `cmd/agent/main.go` — when `RM_TOKEN` is unset, switch to announce mode instead of erroring out. `RM_SERVER` still required.
+- Create: `internal/agent/announce/announce.go` — generate-or-load Ed25519 keypair (persisted as a file alongside `secrets.enc`, mode 0600). POST `/api/agents/announce`. Open `/ws/agent/pending`. Wait. On `enrolled` message, persist bearer to `agent.yaml`, persist repo creds via existing secrets store, exit announce mode and reconnect via the normal WS path.
+- Modify: `deploy/install/install.sh` — when `RM_TOKEN` is missing, run agent in announce mode and `journalctl --follow` until the agent prints the fingerprint, print it to the operator's terminal in big copy-friendly format, then keep following until enrolled.
+- Test: end-to-end test in `internal/server/...` using a fake agent.
+
+- [ ] **Step 10.1** Keypair generation + persistence.
+- [ ] **Step 10.2** Announce client + pending WS client; print `SHA256:…` fingerprint to stdout in a banner.
+- [ ] **Step 10.3** Install script branch.
+- [ ] **Step 10.4** Playwright: register a host via announce mode (run agent locally with no RM_TOKEN), log into UI, see Pending hosts panel with the fingerprint, click Accept, confirm host appears.
+- [ ] **Step 10.5** Commit.
+
+## Task 11 — P2-18d: Pending hosts UI panel
+
+**Files:**
+- Modify: `web/templates/pages/dashboard.html` — add Pending hosts panel above the host list when any pending rows exist.
+- Modify: dashboard handler — `Store.ListPendingHosts(now)` (auto-skips expired).
+- Add buttons → POST `/api/pending-hosts/{id}/accept` and `/reject` via HTMX.
+- Background sweeper for `DeleteExpiredPendingHosts` every 60s (mirror the existing offline-sweeper goroutine pattern).
+
+- [ ] **Step 11.1** Sweeper goroutine.
+- [ ] **Step 11.2** Dashboard handler + template.
+- [ ] **Step 11.3** Accept form must include the same repo URL/user/pw fields as the token-mint form (admin still supplies repo creds at accept time).
+- [ ] **Step 11.4** Playwright sweep.
+- [ ] **Step 11.5** Commit.
+
+## Task 12 — P2-16: Windows service integration
+
+**Decision:** Cannot test on Windows from WSL. Goal is a clean compile under `GOOS=windows GOARCH=amd64` and code that follows the canonical `golang.org/x/sys/windows/svc/example` pattern. Untestable beyond compile + manual review; mark in commit message.
+
+**Files:**
+- Create: `internal/agent/service/service_windows.go` (build tag `//go:build windows`) — implements `svc.Handler`. `Execute` starts the agent's main loop in a goroutine, listens for `svc.Stop`/`svc.Shutdown`, cancels ctx, waits.
+- Create: `internal/agent/service/service_other.go` (build tag `//go:build !windows`) — stub `RunService` that just runs the agent loop in the foreground.
+- Create: `internal/agent/service/install_windows.go` — `Install`, `Uninstall`, `Start`, `Stop` thin wrappers around `mgr` package.
+- Modify: `cmd/agent/main.go` — sub-commands: `install`, `uninstall`, `start`, `stop`, `run` (default). `run` delegates to `service.Run()` which on Windows checks `svc.IsWindowsService()` and dispatches accordingly.
+- Test: `internal/agent/service/service_windows_test.go` (build-tagged) for argv parsing only — actual SCM interaction can't be tested in CI.
+
+- [ ] **Step 12.1** Implement the svc.Handler shell.
+- [ ] **Step 12.2** Install/uninstall wrappers (use `mgr.ConnectLocal()`, `m.CreateService(name, exepath, mgr.Config{...}, "run")`).
+- [ ] **Step 12.3** Cross-compile check: `GOOS=windows GOARCH=amd64 go build ./cmd/agent` must succeed.
+- [ ] **Step 12.4** Commit with note "untested on Windows; compile-verified only".
+
+## Task 13 — P2-17: install.ps1
+
+**Files:**
+- Create: `deploy/install/install.ps1` — PowerShell 5.1+ compatible. Checks admin elevation. Downloads agent binary from `$RM_SERVER/agent/binary?os=windows&arch=amd64`. Drops it at `C:\Program Files\restic-manager\restic-manager-agent.exe`. Runs `restic-manager-agent.exe install` (registers service). Starts it. Detects existing tasks named `*restic*` via `Get-ScheduledTask` and prints them — does not auto-disable. Writes `C:\ProgramData\restic-manager\agent.yaml` with `RM_SERVER` + `RM_TOKEN` (or no token if announce-mode).
+- Modify: `internal/server/http/install.go` (or wherever install scripts are served) to also serve `/install/install.ps1`.
+- Modify: CLAUDE.md restage block to also stage `install.ps1`.
+
+- [ ] **Step 13.1** Write the script.
+- [ ] **Step 13.2** Wire serving + restage.
+- [ ] **Step 13.3** Smoke parse: `pwsh -NoProfile -Command "Get-Command -Syntax (Get-ChildItem deploy/install/install.ps1)"` if pwsh is on PATH, else `Set-StrictMode` parse via `pwsh -c "$null = [scriptblock]::Create((Get-Content deploy/install/install.ps1 -Raw))"`. Skip if no pwsh available — note in commit.
+- [ ] **Step 13.4** Commit.
+
+## Task 14 — Final integration sweep
+
+- [ ] **Step 14.1** `go vet ./... && go test ./... -race`. Full build. Restage. Restart server.
+- [ ] **Step 14.2** Playwright walkthrough on `:8080`: login → dashboard shows pending-hosts empty state → create source group → set a `pre_hook` → Run-now with bandwidth override → confirm hook fires + bandwidth applied → schedules tab shows next/last → repo page shows init-OK line → re-init flow gated by typed hostname.
+- [ ] **Step 14.3** Update `tasks.md`: tick P2R-09, P2R-10, P2R-11, P2R-12, P2R-13, P2R-14, P2-16, P2-17, P2-18 done. Update Phase 2 acceptance line items as satisfied.
+- [ ] **Step 14.4** Open PR `p2-completion → main` with a summary of every item closed.
+
+---
+
+## Decisions made on the operator's behalf (away)
+
+1. **Bandwidth UI for per-job override:** small `<details>` disclosure under each Run-now button. Simpler than a modal; matches the rest of the app's progressive-disclosure style.
+2. **Re-init UX:** server dispatches a fresh `init` job; if restic refuses because the repo already exists, surfaces the error in the job log and instructs the operator to clear the remote bucket. We don't try to forcibly wipe — too dangerous, and the agent doesn't have credentials to wipe S3/B2/etc generically.
+3. **Hooks editor lives on the Repo page (host defaults) + on the source-group edit form (per-group override).** Skips inventing a new "Settings" tab since that surface is still inert.
+4. **Announce flow:** admin still supplies repo creds at accept time (same form as the token-mint flow). The pending row only carries identity-of-the-endpoint material, never repo creds.
+5. **Windows service:** compile-verified only; untested. Commit message will say so.

+Branch: `p5-03-docker-release`. Do not auto-open a PR (see CLAUDE.md
+memory: CI runs are expensive on the self-hosted cluster).

+
+## Slice 1 — Server config + handler fallback
+
+**Goal:** server can serve agent binaries / install scripts from a
+read-only "bundled assets" path when `<DataDir>` doesn't have them.
+
+1. `internal/server/config/config.go` (or wherever `Cfg` lives) gains
+   a `BundledAssetsDir string` field, defaulting to
+   `/opt/restic-manager/dist`. Wire from `RM_BUNDLED_ASSETS_DIR` env
+   var, mirroring the existing env-var conventions.
+2. `internal/server/http/agent_assets.go`:
+   - `handleAgentBinary`: try `<DataDir>/agent-binaries/<name>`
+     first; on `os.Stat` ENOENT, try
+     `<BundledAssetsDir>/agent-binaries/<name>`; on second ENOENT,
+     existing 404.
+   - `handleInstallAsset`: same dual-path, with `install/` subpath.
+3. Tests in `internal/server/http/agent_assets_test.go` (new file):
+   - DataDir hit serves DataDir bytes.
+   - DataDir miss + bundled hit serves bundled bytes.
+   - DataDir hit shadows bundled.
+   - Both miss → 404 + existing error envelope.
+   - Path-traversal still rejected for `install/*` (regression check).
+
+**Verify:** `go vet ./...` + `go test ./internal/server/http/...`.
+

+
+## Slice 2 — Version ldflags on both binaries
+
+1. `cmd/server/main.go`: keep `var version`, add
+   `var commit = "none"` and `var date = "unknown"`. Surface via
+   existing version-log line.
+2. `cmd/agent/main.go`: same three vars. Agent already reports
+   `agent_version` in the WS hello — extend to include commit if
+   it's already plumbed through `internal/api`; otherwise leave the
+   commit out of the wire and just log it on startup.
+3. `Makefile`: extend the `make build` `-ldflags` to set all three
+   from `git describe --tags --always` + `git rev-parse HEAD` +
+   UTC timestamp. Source-build users get real values, not "dev".
+4. `deploy/Dockerfile.server`: add `ARG COMMIT=none` and
+   `ARG DATE=unknown`; pass through `-ldflags`.
+
+**Verify:** `make build && ./bin/restic-manager-server -version`
+(or whatever the existing flag is) prints non-`dev` values.
+
+---
+
+## Slice 3 — Dockerfile bakes agents + install assets
+
+1. Build stage cross-compiles three agents:
+
+   ```dockerfile
+   RUN go build -trimpath -ldflags="-s -w \
+         -X main.version=${VERSION} -X main.commit=${COMMIT} -X main.date=${DATE}" \
+       -o /out/agent/restic-manager-agent-linux-amd64 ./cmd/agent
+   ENV GOARCH=arm64
+   RUN go build ... -o /out/agent/restic-manager-agent-linux-arm64 ./cmd/agent
+   ENV GOOS=windows GOARCH=amd64
+   RUN go build ... -o /out/agent/restic-manager-agent-windows-amd64.exe ./cmd/agent
+   ```
+
+   (Reset `GOOS`/`GOARCH` between layers via `ENV`. Server build
+   stays at `GOOS=linux GOARCH=$TARGETARCH`.)
+
+2. Final stage `COPY --from=build`:
+   - `/out/restic-manager-server` → `/usr/local/bin/`
+   - `/out/agent/*` → `/opt/restic-manager/dist/agent-binaries/`
+   - `deploy/install/install.sh` →
+     `/opt/restic-manager/dist/install/install.sh`
+   - `deploy/install/install.ps1` →
+     `/opt/restic-manager/dist/install/install.ps1`
+   - `deploy/install/restic-manager-agent.service` →
+     `/opt/restic-manager/dist/install/restic-manager-agent.service`
+
+3. Set `--chmod=0755` on the agent binaries and `install.sh`,
+   `--chmod=0644` on the unit file and `install.ps1`. Distroless
+   final stage runs as `nonroot`; bundled assets are readable by
+   anyone (mode `o+r`), so the user switch doesn't break reads.
+
+**Verify:**
+```sh
+docker build -f deploy/Dockerfile.server -t rm:dev .
+docker run --rm -d -p 18080:8080 \
+    -e RM_LISTEN=:8080 -e RM_DATA_DIR=/data \
+    -e RM_BASE_URL=http://127.0.0.1:18080 \
+    -v rm-test:/data rm:dev
+curl -fsSL "http://127.0.0.1:18080/agent/binary?os=linux&arch=amd64" | wc -c
+curl -fsSL "http://127.0.0.1:18080/install/install.sh" | head -1
+```
+
+Both should succeed against a fresh volume (no operator staging).
+
+---
+
+## Slice 4 — Release workflow
+
+`.gitea/workflows/release.yml` per the spec. Two jobs:
+
+1. **`image`**: checkout → setup-qemu → setup-buildx → login → compute
+   tags → buildx build+push.
+2. (Future) `release-notes`: stub left as a TODO comment for now.
+   Operator can hand-write release notes via the Gitea UI on first
+   cut.
+
+The `compute tags` shell step is the only non-trivial bit; tested
+inline by running the script with mocked `GITHUB_REF_TYPE` /
+`GITHUB_REF_NAME` env vars before committing.
+
+**Verify on first dispatch:** trigger `workflow_dispatch` from the
+Gitea UI, check the runner produces `:snapshot-<sha>` and pushes
+multi-arch.
+
+---
+
+## Slice 5 — Tasks.md + commit + push
+
+1. `tasks.md`: tick P5-03; add a one-line note that goreleaser was
+   dropped in favour of Docker-only after a 2026-05-05 design pass
+   (link the spec).
+2. `git add -A && git commit -m "p5-03: docker-only release path"`
+   (no Co-Authored-By trailer — CLAUDE.md rule).
+3. `git push -u origin p5-03-docker-release`.
+4. **Stop.** Do not open a PR. Wait for operator review.

+

+> (P3-05 / P3-06 / P3-07).
+>
+> Wireframe: `_diag/p3-alerts-wireframe/wireframe.html`. Screenshots in the
+> same directory. Spec brainstorm ran 2026-05-04; user approved all ten
+> design decisions before this spec was written.
+
+## Scope locked
+
+Brainstorm decisions (in order asked):
+
+1. **Rule model.** Hardcoded rule set, no operator-tunable thresholds in v1.
+   The engine knows about each rule type internally; per-rule config can land
+   later if/when an operator asks.
+2. **Rule set.** Six rules: `backup_failed`, `forget_failed`, `prune_failed`,
+   `check_failed`, `stale_schedule`, `agent_offline`.
+3. **Engine cadence.** Hybrid. Event hooks at the existing
+   `MarkJobFinished` and offline-sweeper sites for the immediate triggers;
+   one 60-second ticker handles stale-schedule detection and auto-resolution.
+4. **Resolution.** Auto-resolve when the underlying condition clears + manual
+   Resolve at any time. Acknowledge is a separate "I've seen it" intermediate
+   state that does NOT close the alert.
+5. **v1 channels.** Webhook + native ntfy + SMTP. Apprise deferred (the
+   channel plumbing accepts new kinds without reshaping). SMTP added as
+   a first-class channel post-brainstorm because the use case — overnight
+   alerts the operator wants to read in the morning rather than be pinged
+   on at 03:00 — is poorly served by ntfy's push model and clumsy via
+   webhook → email-gateway.
+6. **Channel scope.** Global only. No per-host or per-severity routing in v1.
+7. **Notification body.** Structured JSON for webhooks, formatted
+   title+body+click-URL for ntfy, plus a per-channel "Send test notification"
+   button with inline result feedback.
+8. **Deduplication.** Open-alert uniqueness on `(host_id, kind)` with a
+   `last_seen_at` bump on every confirming tick. One notification per
+   occurrence; the UI shows "still happening · Ns ago" while a rule keeps
+   matching.
+9. **Alert UI.** Top-level `/alerts` page (the existing nav stub becomes
+   real). Per-host vitals "Open alerts" cell links to `/alerts?host_id=...`.
+   Channel CRUD lives at `/settings/notifications`.
+10. **Delivery semantics.** Best-effort fire-and-forget with a 5s timeout
+    per notification. Failures are logged but not retried. The alert row in
+    the DB is the source of truth.
+
+## Architecture
+
+The subsystem is three loosely-coupled units behind one `AlertEngine`
+goroutine:

+### Component boundaries
+
+| Component                                | Purpose                                                                                  | Depends on                             |
+| ---------------------------------------- | ---------------------------------------------------------------------------------------- | -------------------------------------- |
+| `internal/alert.Engine`                  | Owns the rule evaluation. Exposes `OnJobFinished`, `OnHostOffline`, `OnHostOnline` event hooks; runs a 60s ticker for stale-schedule + auto-resolution sweeps. Persists raises/resolves through the store. | store, notification.Hub, slog          |
+| `internal/alert.Rule` + per-rule files   | Each of the six rules is a small struct with `Kind() string`, `Severity() string`, `MessageFor(ctx) string`. The engine iterates over a registered slice. | store models                           |
+| `internal/notification.Hub`              | Receives "alert raised/resolved/test" events; fans out to enabled channels in parallel; logs results to a new `notification_log` table.        | store, channel adapters                |
+| `internal/notification.Channel` (iface)  | Single method `Send(ctx, payload) error` with a 5s context for HTTP channels, 10s for SMTP. Three impls in v1: `webhookChannel`, `ntfyChannel`, `smtpChannel`. | http.Client; net/smtp + crypto/tls for SMTP |
+| `internal/store/alerts.go`               | CRUD on `alerts` table: `RaiseOrTouch(host_id, kind, severity, message)`, `Acknowledge(id, user)`, `Resolve(id, by user)`, `AutoResolve(host_id, kind)`, `ListAlerts(filter)`, plus the `last_seen_at` bump. | sqlite                                 |
+| `internal/store/notification_channels.go` | CRUD on `notification_channels` (new table) + `notification_log` (new table).            | sqlite, crypto.AEAD (for secrets)      |
+| `internal/server/http/ui_alerts.go`      | `/alerts` page handler + filter parsing + ack/resolve form actions.                      | store                                  |
+| `internal/server/http/ui_notifications.go` | `/settings/notifications` page + channel CRUD + "Send test" handler.                   | store, notification.Hub                |
+
+### Engine event shape
+
+The engine runs as one goroutine per server process started in
+`cmd/server/main.go`. It exposes a small set of channels other code writes to:
+
+```go
+type Engine struct {
+    store *store.Store
+    hub   *notification.Hub
+
+    // Event channels (buffered, drop-on-full with a slog warning to keep
+    // hot paths non-blocking). The engine drains them on its own
+    // goroutine, evaluates the rule, and acts.
+    jobFinished chan jobFinishedEvent  // from store.MarkJobFinished hook
+    hostOffline chan string            // host_id; from offline sweeper
+    hostOnline  chan string            // host_id; from ws handler hello
+
+    // 60s ticker drives stale-schedule + auto-resolution sweeps.
+    tick *time.Ticker
+}
+```
+
+The hot-path call sites (`store.MarkJobFinished`, `ws.handler` offline
+sweep, `ws.handler` hello) push to these channels via a tiny
+`Engine.Notify*` method that does a non-blocking send. The engine's own
+goroutine handles every match — keeps mutation off the hot path.
+
+### Rule catalogue
+
+| Kind                | Severity | Trigger                                                                 | Auto-resolve when                                  |
+| ------------------- | -------- | ----------------------------------------------------------------------- | -------------------------------------------------- |
+| `backup_failed`     | warning  | `MarkJobFinished` with kind=backup, status=failed                       | next backup for the same host succeeds             |
+| `forget_failed`     | warning  | `MarkJobFinished` with kind=forget, status=failed                       | next forget for the same host succeeds             |
+| `prune_failed`      | warning  | `MarkJobFinished` with kind=prune, status=failed                        | next prune for the same host succeeds              |
+| `check_failed`      | critical | `MarkJobFinished` with kind=check, status=failed OR errors_found        | next check for the same host succeeds without errors |
+| `stale_schedule`    | warning  | 60s ticker: a schedule's next-fire time is more than 5 minutes in the past with no matching job since | next job for that schedule succeeds OR schedule deleted |
+| `agent_offline`     | warning  | offline-sweeper marks the host offline AND the host has been offline > 15 min (engine checks `last_seen_at`) | hostOnline event for that host                     |
+
+The 15-minute floor on `agent_offline` exists so a 30-second blip during
+agent restart doesn't generate a notification storm. The store's existing
+offline sweeper (`hosts.last_seen_at` with 90s threshold) already marks the
+host offline; the engine sees the event but waits for the threshold before
+raising.
+
+### Dedup + last_seen_at
+
+`store.RaiseOrTouch(host_id, kind, severity, message)`:
+
+```sql
+SELECT id, last_seen_at FROM alerts
+ WHERE host_id = ? AND kind = ? AND resolved_at IS NULL
+ LIMIT 1;
+```
+
+- Found: `UPDATE alerts SET last_seen_at = ?, message = ? WHERE id = ?`,
+  return `(id, didRaise=false)`.
+- Not found: `INSERT INTO alerts (id, host_id, kind, severity, message,
+  created_at, last_seen_at) VALUES (?, ?, ?, ?, ?, ?, ?)`, return
+  `(id, didRaise=true)`.
+
+The engine fires a notification through the Hub only when `didRaise=true`.
+Touch-only events keep the row's `last_seen_at` fresh so the UI can render
+"still happening · Ns ago" without spamming the operator's phone.
+
+### Notification payload shapes
+
+**Webhook** — a single JSON envelope per event:
+
+```json
+{
+  "event":     "alert.raised",
+  "alert_id":  "01KQT...",
+  "severity":  "warning",
+  "kind":      "backup_failed",
+  "host_id":   "01KQ...",
+  "host_name": "alfa-01",
+  "message":   "Backup 'system-config' failed: rest-server returned 401",
+  "raised_at": "2026-05-04T15:42:01Z",
+  "link":      "https://restic-manager.example/alerts/01KQT..."
+}
+```
+
+`event` is one of `alert.raised | alert.acknowledged | alert.resolved |
+alert.test`. The same envelope shape is reused across events — operators
+build one bridge, switch on `event` and `severity`.
+
+**SMTP** — single-recipient plain-text email per channel. The channel
+config carries the SMTP server credentials and a `to` address; one
+channel = one recipient (or one distribution-list address). Operators
+who want multiple recipients add multiple channels — keeps the config
+flat and the failure modes per-recipient.
+
+Subject pattern is hardcoded (no per-channel template in v1):
+
+```
+Subject: [restic-manager] [<severity>] <host_name>: <kind>
+From: <configured-from-address>
+To: <configured-to-address>
+Date: <RFC 5322>
+Message-ID: <alert_id@<server-host>>
+
+<message line — same string the webhook/ntfy gets>
+
+—
+Raised at: 2026-05-04T15:42:01Z
+Severity:  warning
+Host:      alfa-01
+Kind:      backup_failed
+
+Open in restic-manager:
+https://restic-manager.example/alerts/01KQT...
+
+(This message was sent by restic-manager. Acknowledge or resolve in the UI.)
+```
+
+The body is plain text only in v1 — no HTML alternative — both because
+the data is already structured well enough as text and because HTML
+email opens a long tail of rendering / sanitisation concerns. The
+`Message-ID` includes the alert id so a thread-aware client can group
+related events (raised → acknowledged → resolved) together.
+
+Encryption:
+- **STARTTLS** (default, port 587). Opportunistic upgrade. Most
+  operator-facing relays.
+- **Implicit TLS** (port 465). Connect-then-TLS-handshake.
+- **None** (port 25). Plain. Hidden behind a "Yes I understand" warning
+  on the form because the password goes over the wire.
+
+Auth:
+- **PLAIN** (RFC 4616) over TLS. Default and almost always what's wanted.
+- **CRAM-MD5** (RFC 2195). Offered if the server advertises it, no UI
+  toggle — automatic.
+- No OAuth2 / XOAUTH2 in v1; that's a real next step if Gmail-without-
+  app-passwords becomes a recurring ask.
+
+Per-message timeout is 10s (vs 5s for HTTP channels) — STARTTLS
+handshake + DATA over a slow link can legitimately take that long.
+
+**Ntfy** — uses the standard publish format:
+
+```
+POST /<topic> HTTP/1.1
+Host: <server>
+Authorization: Bearer <access-token>   (if configured)
+Title: [warning] alfa-01 backup failed
+Priority: 4
+Tags: warning,backup_failed
+Click: https://restic-manager.example/alerts/01KQT...
+
+Backup 'system-config' failed: rest-server returned 401
+```
+
+Severity → priority mapping:
+
+| Severity  | Priority |
+| --------- | -------- |
+| info      | 3 (default) |
+| warning   | 4 (high)    |
+| critical  | 5 (urgent)  |
+
+Per-channel `default_priority` setting overrides for non-critical alerts;
+critical always goes urgent regardless.
+
+### Test notification
+
+`POST /api/notifications/{channel_id}/test` builds a synthetic event
+(severity=info, kind=test_notification, message="Test from
+restic-manager", link to the channel's edit page) and runs it through the
+real send path. Returns `{ok: bool, latency_ms: int, status_code?: int,
+error?: string}`. UI renders the green ✓ / red ✗ feedback inline.

+`config` is an AEAD-encrypted JSON blob — bearer tokens for webhooks and

+    BearerToken  string `json:"bearer_token,omitempty"`
+    HeaderName   string `json:"header_name,omitempty"`
+    HeaderValue  string `json:"header_value,omitempty"`
+}
+
+type ntfyConfig struct {
+    ServerURL    string `json:"server_url"`     // default https://ntfy.sh
+    Topic        string `json:"topic"`
+    AccessToken  string `json:"access_token,omitempty"`
+}
+
+type smtpConfig struct {
+    Host       string `json:"host"`         // e.g. smtp.example.com
+    Port       int    `json:"port"`         // default 587 (STARTTLS), 465 (TLS), 25 (none)

+    From       string `json:"from"`         // RFC 5322 address; "alerts@example.com" or "Restic-Manager <alerts@…>"
+    To         string `json:"to"`           // single recipient or distribution-list address; v1 = one channel = one to-line
+}
+```
+
+### Engine state
+
+The engine itself is stateless beyond the channels it owns; all
+persisted state is in the existing `alerts` table + the new
+`notification_log` table. A process restart re-evaluates from scratch:
+on next tick the stale-schedule + auto-resolution sweeps catch up with
+whatever happened during the downtime. No outbox to drain.
+
+## UI templates
+
+| Template                                  | Purpose                                                |
+| ----------------------------------------- | ------------------------------------------------------ |
+| `web/templates/pages/alerts.html`         | Fleet alerts page                                      |
+| `web/templates/partials/alert_row.html`   | One alert row (used by both list and detail-fragment swap) |
+| `web/templates/pages/settings.html`       | Settings shell with Notifications / Users / Auth sub-tabs |
+| `web/templates/pages/notifications.html`  | Channel list (Notifications sub-tab body)              |
+| `web/templates/pages/notification_edit.html` | Channel kind picker + per-kind form + test button + payload preview |
+| `web/templates/partials/crit_banner.html` | Dashboard top-of-page banner                           |
+| `web/templates/partials/nav.html`         | Existing — gain a `data-alerts-count` attribute on the Alerts tab so the badge auto-updates |
+
+The Settings shell + Notifications sub-tab is the new chrome the wireframe
+introduced; Users + Authentication tabs are placeholder links that 404 in
+v1 (or render an "Lands later" notice). Same pattern P2R-02 used for
+inert sub-tabs.
+
+## Tests (target coverage)
+
+- `internal/alert/engine_test.go` — rule firing per kind: backup_failed
+  raises on `MarkJobFinished(kind=backup, status=failed)`; touch-only on
+  the second failure for the same host (no second notification);
+  auto-resolve on next success.
+- `internal/alert/agent_offline_test.go` — `OnHostOffline` emits without
+  raising until the 15-min floor; `OnHostOnline` clears the alert.
+- `internal/alert/stale_schedule_test.go` — synthetic schedule whose next
+  fire is in the past triggers; resets when a job lands.
+- `internal/notification/webhook_test.go` — payload shape pinned;
+  authorisation header sent when bearer set; custom header echoed; 5s
+  timeout enforced; error in `notification_log`.
+- `internal/notification/ntfy_test.go` — title/priority/tags/click headers
+  match the severity mapping; access token sent as `Authorization: Bearer
+  <token>`; default priority overridden by severity for critical.
+- `internal/notification/smtp_test.go` — round-trip against a local
+  `net/smtp.NewServer`-style fake (or `mhog`/MailHog if convenient):
+  STARTTLS handshake completes against a self-signed cert; PLAIN auth
+  uses configured creds; subject + from + to + body bytes match the
+  spec'd format; Message-ID contains the alert id; 10s timeout enforced;
+  failure path (auth refused) lands in `notification_log` with the
+  server's error string.
+- `internal/server/http/ui_alerts_test.go` — page renders with filters
+  applied; ack/resolve POSTs flip the row + write audit; HX-Redirect
+  bounces back to the filtered list.
+- `internal/server/http/ui_notifications_test.go` — CRUD happy paths,
+  validation re-render, secrets-encrypted-at-rest assertion (load row,
+  decrypt, compare), test-button hits the real send path against a
+  test http.Server.
+- Migration 0013 + 0014 round-trip tested via `store.Open` on a fresh
+  db.
+
+## Playwright sweep
+
+End-of-phase sweep mirrors the P2R-02 / P3-restore pattern:
+
+1. Login → `/alerts` (initially empty) → see "All clear · last alert
+   never" empty state.
+2. Trigger a fake-failed-backup via `POST /api/hosts/{id}/jobs` against a
+   host with a deliberately-wrong rest-server URL. Wait for the
+   `backup_failed` alert to appear in the list within ~2s of the job
+   finishing.
+3. Acknowledge → row tints + ack actor visible.
+4. Take the agent offline (`systemctl stop`); wait 15 min OR mock
+   `last_seen_at` to 16 min ago via the test harness; confirm
+   `agent_offline` alert raises once.
+5. Restart the agent → `agent_offline` auto-resolves; `backup_failed` is
+   still open.
+6. Configure a webhook channel pointing at a local test sink; click "Send
+   test" → green ✓.
+7. Configure a ntfy channel pointing at a local sink → click "Send test"
+   → green ✓.
+8. Configure an SMTP channel pointing at a local MailHog (Docker, port
+   1025, no TLS for the local-only sweep) → click "Send test" → green ✓
+   → MailHog UI at :8025 shows the test email with the right subject
+   and Message-ID.
+9. Trigger a fresh failed backup → all three channels receive the
+   notification (verified from sink logs + MailHog inbox);
+   `notification_log` has three rows `event=alert.raised, ok=true`.
+10. Manually Resolve the open `backup_failed`; confirm all three channels
+    receive `event=alert.resolved`.
+11. Critical-severity test: trigger `check_failed` (mocked) → dashboard
+    banner appears; clicking it lands on `/alerts?severity=critical&status=open`.
+12. Empty the alerts again → banner disappears.
+
+Screenshots into `_diag/p3-alerts-sweep/`. End-to-end clean, zero console
+errors, before handing back.
+
+## What does NOT change
+
+- Existing chrome/templates beyond the small additions noted above.
+- Existing `alerts.severity` CHECK (`info`/`warning`/`critical`) — already
+  the right shape; no migration needed for that.
+- Audit log writer pattern — engine writes audit rows for ack/resolve
+  the same way every other state-changing handler does.
+- The agent. Alerts are entirely a server concern; the agent doesn't
+  know they exist.
+
+## Open questions / explicit non-goals
+
+- **Per-rule cooldowns / re-raise on long-running issues.** Out of scope
+  (brainstorm question 8 ruled this out). Operators see "still happening"
+  in the UI; they don't get a reminder ping.
+- **SMTP HTML emails.** v1 is plain text only — operators wanting rich
+  rendering can deploy a webhook → mail-merge bridge, or wait for a v2
+  template engine. The Message-ID threading + plain text body should be
+  enough for almost every overnight-digest workflow.
+- **SMTP OAuth2 / XOAUTH2.** Out of scope. Gmail / Microsoft 365 with
+  modern OAuth requires an `app password` workaround in v1. Native
+  XOAUTH2 lands when an operator asks (or when Google starts refusing
+  app passwords for non-business accounts in earnest).
+- **Multi-recipient SMTP channels.** A channel = one `To`. Operators
+  wanting multiple recipients add multiple channels. Keeps failure
+  attribution per-recipient.
+- **Apprise sidecar integration.** Deferred per brainstorm. The
+  `Channel` interface accepts a third impl without reshaping when we get
+  there.
+- **Per-host or per-severity channel routing.** Out of scope. Likely
+  next step if operators ask: a `min_severity` field on the channel row.
+- **Snooze / mute.** Out of scope. Acknowledge is the closest analogue;
+  full silence-windows would need a new table and is YAGNI for v1.
+- **PagerDuty / OpsGenie.** Both have webhook receivers; operators wire
+  them via the webhook channel today.
+- **Alert "rules" UI.** No CRUD; the rule set is hardcoded.

+# P3 — Restore (design)
+
+> Phase 3 sub-spec covering single-host restore (P3-01, P3-02, P3-03, P3-09).
+> P3-04 (cross-host restore) is deferred to a new "Future / unscheduled"
+> section in `tasks.md` — disaster recovery is already covered by re-enrolling
+> a replacement host with the same repo credentials.
+>
+> Wireframe: `_diag/p3-restore-wizard/wireframe.html`. Screenshot:
+> `_diag/p3-restore-wizard/01-full-wizard.png`.
+
+## Scope locked
+
+Brainstorm decisions (in order asked):
+
+1. **In-place vs new-directory.** Default is a new directory under
+   `/var/restic-restore/<job-id>/`. An "Restore in place (overwrite original
+   paths)" toggle is gated by typed-confirmation of the host name, mirroring
+   the repo re-init pattern.
+2. **Path-selection granularity.** Tree browser as the path selector, lazy-
+   loaded via `restic ls --json <snapshot> <path>` per directory expansion.
+3. **Cross-host restore (P3-04).** Out of scope this phase. Move to
+   "Future / unscheduled" in `tasks.md`. The disaster-recovery case is covered
+   by the standard enrolment flow: stand up a replacement host, paste the
+   original repo creds at enrolment, snapshots reappear, restore is
+   same-host.
+4. **Snapshot diff (P3-09).** Diff-as-a-job. New `JobDiff` JobKind dispatched
+   like every other agent operation. Output streams as `log.stream` and
+   renders on the live job log page.
+5. **Wizard entry points.** Top-level "Restore" button on host detail
+   (`/hosts/{id}/restore`, opens wizard at step 1) plus a per-snapshot
+   Restore action on snapshot rows (`/hosts/{id}/snapshots/{sid}/restore`,
+   skips step 1).
+6. **Wizard interaction model.** Single-page, sections progressively enable;
+   tree-browser nodes lazy-load via HTMX partials. No `restore_drafts` table.
+7. **Tree-browser data path.** Synchronous WS RPC (`tree.list` ↔
+   `tree.list.result`, correlation-ID) plus a per-wizard-session in-memory
+   cache keyed by `{snapshot_id, path}` with ~30-min TTL.
+8. **Restore progress UI.** Restore-specific job-page variant: files-restored
+   / bytes-restored / throughput / ETA / current-file display, driven by
+   restic restore's JSON status events surfaced through `job.progress`.
+9. **Permissions/ownership.** Policy, not toggle. In-place restore preserves
+   original ownership; new-directory restore drops ownership
+   (`--no-ownership`).
+10. **Concurrency.** Single-flight per host (one job at a time across all
+    kinds). Plus a real cancel-job feature: `command.cancel` envelope, agent
+    kills the `restic` subprocess via context cancel (SIGTERM, SIGKILL after
+    grace), server transitions the job to `cancelled`. The "Cancel" button
+    already in the `job_detail` template becomes real for any running job
+    kind.
+11. **Audit + safety.** Audit row on every restore dispatch (`host.restore`
+    with snapshot ID, paths, target, in-place flag). Recent-restores panel
+    on the host page surfacing the latest restore job alongside last-backup
+    and last-init signals. Role gate deferred to P4-03.
+
+## Architecture
+
+Restore composes from existing primitives plus three new pieces:
+
+- **New JobKind values**: `JobRestore`, `JobDiff`. Dispatcher cases mirror
+  the prune/check pattern. Agent-side handlers wrap `restic.RunRestore` and
+  `restic.RunDiff` (new methods on the `restic` package).
+- **New WS RPC**: `tree.list` request (`{snapshot_id, path}`) ↔
+  `tree.list.result` reply (`{entries: [{name, type, size}], ...}` or
+  `{error}`). Reuses existing correlation-ID infrastructure from P1-09. No
+  `jobs` row.
+- **New cancel surface**: `command.cancel` request (`{job_id}`), agent
+  cancels the running subprocess context, returns `command.ack` + `job.finished`
+  with status `cancelled`. Server endpoint `POST /api/jobs/{id}/cancel`
+  bridges UI button → WS envelope.
+
+Everything else (job lifecycle, log streaming, progress envelope, snapshot
+listing, audit log writer, host_chrome partial, danger-zone typed-confirmation)
+already exists and is reused verbatim.

+### Data flow — wizard happy path
+
+```
+operator
+  ├─ GET /hosts/{id}/restore
+  │     server renders wizard shell, snapshot table from store.ListSnapshotsByHost
+  │
+  ├─ click snapshot row (or arrives via /hosts/{id}/snapshots/{sid}/restore)
+  │     wizard advances to step 2, snapshot summary card rendered
+  │
+  ├─ expand a tree node (chevron click)
+  │     HTMX GET /hosts/{id}/restore/tree?snapshot={sid}&path=/etc
+  │       server checks per-session cache (keyed by sid+path)
+  │         hit  → render tree_node fragment from cache
+  │         miss → hub.SendRPC(host_id, "tree.list", {sid, path}) → wait reply
+  │                cache result, render tree_node fragment
+  │
+  ├─ tick file/dir checkboxes (form state, no round-trip)
+  │
+  ├─ pick target radio (and optionally type host name to unlock in-place)
+  │
+  └─ POST /hosts/{id}/restore  (form submit)
+        server validates: ≥1 path, target mode, in-place ⇒ host name match
+        write audit row host.restore
+        store.CreateJob{kind=restore, payload={snapshot_id, paths, target, in_place}}
+        hub.Send(host_id, "command.run", {job_id, kind=restore, payload})
+        HX-Redirect: /jobs/{job_id}
+```
+
+### Data flow — agent restore execution
+
+```
+agent.runner receives command.run kind=restore
+  ├─ check single-flight: if r.activeJobID != "" → reply busy
+  │   (server queues to pending_runs only for kind=backup; restore returns busy)
+  ├─ allocate ctx, ctxCancel — store cancelFunc against job_id in r.cancels
+  ├─ sendStarted(job_id, JobRestore, now)
+  ├─ build target path: if in_place → "/" else "/var/restic-restore/<job_id>/"
+  ├─ build flags: paths from payload, --no-ownership when !in_place
+  ├─ restic.RunRestore(ctx, env, snapshot_id, paths, target, in_place):
+  │   restic restore <sid> --target <path> [--no-ownership] -- <p1> <p2> ...
+  │   parse stdout JSON: forward "status" → job.progress (1Hz throttle), "summary" → final
+  ├─ on success: sendFinished(job_id, succeeded, exit=0)
+  ├─ on ctx.Err() == context.Canceled: sendFinished(job_id, cancelled, exit=130)
+  └─ delete cancel func from r.cancels
+```
+
+### Data flow — cancel
+
+```
+operator clicks Cancel on /jobs/{id} (running)
+  POST /api/jobs/{id}/cancel
+    server: lookup job, ensure status=running, find host
+    hub.Send(host_id, "command.cancel", {job_id})
+  → agent.runner receives command.cancel
+       cancelFunc, ok := r.cancels[job_id]
+       ok && cancelFunc()
+       → restic subprocess context done → exec.Cmd kills via SIGTERM
+       → if still alive after 5s grace → SIGKILL
+       → runner sendFinished(job_id, cancelled, exit=130)
+  → server receives job.finished status=cancelled, persists, broadcasts
+  → browser refresh shows cancelled state
+```
+
+The cancel surface is independently useful for any kind (prune/check/backup) —
+not gated to restore. The button already in `job_detail.html` becomes real.
+
+### Tree-list RPC details
+
+New WS message types (added to `internal/api/messages.go`):
+
+```
+type TreeListRequestPayload struct {
+    SnapshotID string `json:"snapshot_id"`
+    Path       string `json:"path"`
+}
+
+type TreeListEntry struct {
+    Name string `json:"name"`
+    Type string `json:"type"`        // "dir" | "file" | "symlink"
+    Size int64  `json:"size,omitempty"`
+}
+
+type TreeListResultPayload struct {
+    SnapshotID string          `json:"snapshot_id"`
+    Path       string          `json:"path"`
+    Entries    []TreeListEntry `json:"entries,omitempty"`
+    Error      string          `json:"error,omitempty"`
+}
+```
+
+Server-side mediator (`ws.SendRPC`) takes a request envelope, registers the
+correlation ID in a pending map, sends, blocks on a per-call channel until
+the matching reply arrives (or 30s timeout). The pattern is small enough
+to inline in `internal/server/ws/rpc.go` as a generic helper — future
+synchronous RPCs reuse it.
+
+In-memory cache: `map[sessionID]map[cacheKey]TreeListResultPayload` with
+`cacheKey = snapshot_id + "\x00" + path`. Session ID minted per wizard
+load (HTTP-only cookie scoped to `/hosts/{id}/restore/tree`, lifetime 30
+min). On wizard close (browser navigation away) the entry expires
+naturally. No persistence, no migration.
+
+Agent handler runs `restic ls --json <sid> <path>` (non-recursive — restic
+defaults to recursive but `restic ls` accepts `--long` and a path filter;
+parse output line-by-line and emit only direct children of `path`). 60s
+context timeout, mirroring existing `restic snapshots` invocation.
+
+### Restore payload
+
+`api.CommandRunPayload` gains a nested optional `restore` field:
+
+```
+type RestorePayload struct {
+    SnapshotID    string   `json:"snapshot_id"`
+    Paths         []string `json:"paths"`           // absolute paths inside the snapshot
+    InPlace       bool     `json:"in_place"`
+    TargetDir     string   `json:"target_dir"`      // empty when in_place=true
+    PreserveOwner bool     `json:"preserve_owner"`  // mirrors policy: in_place=>true, else=>false
+}
+```
+
+The payload is set by the server when dispatching `JobRestore` and ignored
+on every other kind. Wire-shape test pinned in `wire_test.go`.
+
+### Diff payload
+
+`api.CommandRunPayload` gains:
+
+```
+type DiffPayload struct {
+    SnapshotA string `json:"snapshot_a"`
+    SnapshotB string `json:"snapshot_b"`
+}
+```
+
+Set on `JobDiff`. Output is plain `restic diff --json <a> <b>` forwarded as
+`log.stream` lines. Job page renders unchanged — operator reads the diff
+output directly.
+
+### Recent-restores panel
+
+A small panel rendered on the host detail page below the existing init-status
+line:
+
+```
+last restore: succeeded 2h ago · job f73ab4c1… · 3 files to /var/restic-restore/...
+```
+
+Backed by a new `store.LatestJobByKind(host_id, JobRestore)` query (mirroring
+the existing `store.LatestJobByKind` already used for init/forget/prune/check
+in P2R-06). One template addition in `host_chrome.html` next to the
+`InitStatus` block.

+
+## Migrations
+
+None. Restore + diff piggyback on the existing `jobs` table (their `kind` is
+new but the schema already accepts arbitrary kind strings — there's no
+CHECK constraint on `kind`). The cancel feature uses the existing
+`JobCancelled` terminal status. The tree-list cache lives in process memory.
+
+## Tests (target coverage)
+
+- `internal/restic/restore_test.go` — `RunRestore` invocation builds the
+  expected argv (paths, --target, --no-ownership flag presence, in-place
+  variant); JSON status parsing → `BackupStatus`-shaped progress envelopes.
+- `internal/restic/diff_test.go` — `RunDiff` argv shape and JSON forwarding.
+- `internal/agent/runner/restore_test.go` — happy path, cancel mid-run
+  produces `cancelled` finished, in-place vs new-directory dispatch,
+  single-flight rejects when another job is running.
+- `internal/agent/runner/tree_test.go` — `tree.list` handler returns
+  direct children for a synthetic restic ls output, surfaces error on
+  missing snapshot.
+- `internal/server/ws/rpc_test.go` — `SendRPC` correlation matching,
+  timeout, concurrent calls.
+- `internal/server/http/restore_test.go` — wizard renders with snapshots,
+  POST validates ≥1 path + in-place host-name match, audit row written,
+  job dispatched with correct payload, in-place without typed-confirm
+  re-renders form with input intact and an error.
+- `internal/server/http/diff_test.go` — POST dispatches `JobDiff`,
+  snapshot IDs validated against the host's snapshot list.
+- `internal/server/http/cancel_test.go` — POST cancel happy path
+  (running → cancelled), 4xx for non-running jobs, 4xx when host offline.
+- `internal/server/http/restore_e2e_test.go` — happy path: GET wizard,
+  expand `/etc` (HTMX call returns expected fragment), submit, follow
+  HX-Redirect to job page, see status.
+- `web/templates/pages/host_restore_test.go` (template-render test) —
+  wizard renders all four sections; in-place card disabled until typed
+  confirm.
+
+## Playwright iteration / sweep
+
+A Playwright sweep at the end (mirroring P2R-02 Slice 6) runs against the
+local smoke server with a real agent enrolled. Steps:
+
+1. Login → navigate to alfa-01 host → click Restore.
+2. Wizard step 1: pick the most recent snapshot.
+3. Wizard step 2: expand a directory two levels, tick three files,
+   verify tally updates.
+4. Wizard step 3: leave default new-directory.
+5. Wizard step 4: dispatch.
+6. Land on live job page, see progress widget animating, see log lines.
+7. Click Cancel mid-flight, verify status transitions to cancelled and
+   the agent's subprocess actually died (log line `signal: killed` or exit
+   130).
+8. Repeat with in-place mode: type host name, dispatch, verify red
+   primary button, verify files actually overwritten on host.
+9. Snapshot diff: navigate to snapshots, pick two, dispatch diff, see
+   diff output streamed.
+10. Screenshots into `_diag/p3-restore-sweep/`.
+
+End-to-end clean, zero console errors, before handing back.
+
+## What does NOT change
+
+- `host_chrome.html` only grows the recent-restores line; sub-tab list
+  unchanged (Restore is a top-level button on the host page, not a sub-tab).
+- `enrollment.go`, schedule reconciliation, source-group CRUD, repo
+  maintenance ticker, hook execution — none of these are touched.
+- The CLAUDE.md restage block applies as-is when the agent binary changes
+  (it does — runner gains restore/diff/cancel/tree handlers). The unit
+  file does not change.
+
+## Open questions / explicit non-goals
+
+- **Restore preview / dry-run.** Restic doesn't have a dry-run for restore.
+  Out of scope.
+- **Resumable restore.** Restic restore is idempotent per-file but not
+  resumable mid-stream from where it left off. If a restore is cancelled,
+  the operator re-runs (files already written are overwritten). No state
+  to track.
+- **Restore to a glob/pattern (e.g. `*.conf`).** Out of scope; the tree
+  picker requires explicit ticks. Power users can edit the URL or use the
+  CLI.
+- **Bandwidth caps for restore.** Honoured automatically — restic's
+  `--limit-download` is part of `restic.Env` already (P2R-13) and applies
+  to restore unchanged.
+- **Pre/post hooks for restore.** Hooks today gate only `kind=backup`
+  (P2R-11). Out of scope.

+# P4-03 / P4-04 — RBAC + User Management Design
+
+> **Date:** 2026-05-05
+> **Status:** brainstorm complete; ready for plan
+> **Closes:** P4-03 (RBAC enforcement at API layer), P4-04 (User management UI)
+
+## Goal
+
+Enforce role-based access control at the HTTP layer (currently every authenticated user has admin powers) and ship the operator-facing screens for managing users, roles, and password lifecycle.
+
+## Architecture
+
+Two coupled subsystems landing in one PR:
+
+1. **RBAC enforcement** — chi route-group middleware that gates each subtree by minimum role. Fail-closed default (admin) so a forgotten declaration doesn't accidentally widen access.
+2. **User management** — `/settings/users` sub-tab with list / add / edit / disable. Setup-link flow for new users (1-hour-expiry single-use token). Self-service password change at `/settings/account`.
+
+The audit log already records actor + user_id on every mutation; new endpoints fold in naturally.
+
+## Role taxonomy
+
+Locked. Three roles, hierarchical (admin ⊇ operator ⊇ viewer):
+
+| Action | admin | operator | viewer |
+|---|:-:|:-:|:-:|
+| View dashboard / alerts / audit / hosts | ✓ | ✓ | ✓ |
+| Trigger Run-now / Restore / Snapshot diff | ✓ | ✓ | ✗ |
+| Acknowledge / resolve alerts | ✓ | ✓ | ✗ |
+| Edit schedules / source groups / retention / hooks | ✓ | ✓ | ✗ |
+| Add / remove hosts (enrolment, accept/reject pending) | ✓ | ✓ | ✗ |
+| Cancel running jobs | ✓ | ✓ | ✗ |
+| Edit repo credentials | ✓ | ✓ | ✗ |
+| Edit notification channels | ✓ | ✗ | ✗ |
+| Manage users | ✓ | ✗ | ✗ |
+| Self password change (`/settings/account`) | ✓ | ✓ | ✓ |
+
+The role enum already exists in the schema (`CHECK (role IN ('admin','operator','viewer'))`) and in `internal/store/types.go`. Bootstrap creates the first user as admin. Zero migration needed for existing installs.
+
+## Schema changes
+
+All column-level ALTERs (CLAUDE.md prefers these over rebuilds; safe under `foreign_keys=ON`).
+
+### Migration 0017 — `users` extensions
+
+```sql
+ALTER TABLE users ADD COLUMN email TEXT;
+ALTER TABLE users ADD COLUMN disabled_at TEXT;
+ALTER TABLE users ADD COLUMN must_change_password INTEGER NOT NULL DEFAULT 0;
+
+-- Username case-insensitive lookup. Existing rows are kept as-is;
+-- normalisation only applies to new INSERTs (handled in Go).
+CREATE UNIQUE INDEX users_username_lower ON users(LOWER(username));
+```
+
+### Migration 0018 — `user_setup_tokens`
+
+```sql
+CREATE TABLE user_setup_tokens (
+  user_id     TEXT PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
+  token_hash  TEXT NOT NULL,           -- sha256(raw_token), hex
+  expires_at  TEXT NOT NULL,
+  created_at  TEXT NOT NULL,
+  created_by  TEXT NOT NULL REFERENCES users(id) ON DELETE SET NULL
+);
+
+CREATE INDEX user_setup_tokens_expires ON user_setup_tokens(expires_at);
+```
+
+`user_id` is PRIMARY KEY, not just FOREIGN KEY — only one outstanding setup token per user. Regenerating supersedes the old via `INSERT OR REPLACE`.
+
+## RBAC enforcement
+
+### Middleware
+
+```go
+// requireRole returns chi middleware that 403s any request whose
+// session-resolved user doesn't meet the minimum role. Roles are
+// hierarchical: admin > operator > viewer.
+func (s *Server) requireRole(min store.Role) func(http.Handler) http.Handler
+```
+
+Hierarchy implemented as a small helper:
+
+```go
+func roleAtLeast(have, min store.Role) bool {
+    rank := map[store.Role]int{
+        store.RoleViewer:   1,
+        store.RoleOperator: 2,
+        store.RoleAdmin:    3,
+    }
+    return rank[have] >= rank[min]
+}
+```
+
+### Route grouping in `server.go`
+
+The existing `/api` and UI routes get re-grouped into three role bands plus a self-service group:
+
+```
+/api/* viewer-readable    — GET endpoints anyone authenticated can hit
+/api/* operator+          — mutating endpoints up to host/source-group/schedule level
+/api/* admin-only         — /api/users/*, channel CRUD
+/api/account              — self-service password change
+
+/audit, /alerts, /hosts/{id}, etc.   — viewer
+/hosts/{id}/run, /alerts/{id}/ack    — operator
+/settings/users/*, /settings/notifications/* — admin
+/settings/account                    — viewer (any authenticated)
+```
+
+Default at the bottom of `routes()` is admin (fail-closed). Any future endpoint that doesn't get explicitly placed lands in admin-only, surfacing the missing declaration as a permission error rather than a silent bypass.
+
+### Per-handler nuance
+
+One existing case warrants a handler-level check on top of the route gate: `GET /settings/users/{id}/edit` is admin-only, but the `PUT /api/account/password` is viewer-OK. The split-by-route already covers this; no per-handler overrides expected in v1.
+
+### Out of scope of role middleware
+
+- `/ws/agent` and `/api/agents/*` — agent bearer-token auth, separate chain
+- `/healthz` — unauthenticated
+- `/login`, `/logout`, `/bootstrap` — public
+
+### 403 handling
+
+- JSON endpoints: `{"error":"forbidden","code":"insufficient_role"}` with HTTP 403
+- HTML endpoints: render a small "You don't have permission" panel inside the chrome (so the user keeps their nav and can move away), HTTP 403
+- **No audit row on 403** — too noisy with normal users hitting URLs they don't have access to
+
+### Session re-validation
+
+Sessions need to honour `disabled_at` and current role on every request, not just at login. The session-validation middleware reads the user row each request (single PK lookup, fast in SQLite). If `disabled_at IS NOT NULL`, the session is invalidated and the request 401s. This makes "disable user" and "force logout" effectively immediate.
+
+Cost: one SELECT per authenticated request. SQLite handles this comfortably for the fleet sizes this codebase targets.
+
+## Setup-token flow (replacing temp passwords)
+
+### Add user
+
+1. Admin clicks **+ Add user** on `/settings/users`
+2. Form: username (required, lowercase-normalised), email (optional, validated), role (admin/operator/viewer)
+3. Server:
+   - Validates username uniqueness (case-insensitive). On collision with a *disabled* user, return a 409 with `{"existing_user_id": "...", "disabled": true}` so the UI can pivot to a "re-enable existing user" prompt
+   - On collision with an enabled user: 409 with a plain "username taken" error
+   - Creates user row with `password_hash = ""`, `must_change_password = 1`, `disabled_at = NULL`
+   - Generates 32 random bytes, hex-encodes → raw token (64 chars). Stores `sha256(token)` hex in `user_setup_tokens`. `expires_at = now + 1h`
+   - Audit: `user.created`, payload `{"username": "...", "role": "...", "with_setup_token": true}`
+4. Server returns the admin to a one-time setup-link page: `/settings/users/{id}/setup-link`
+   - Shows the URL `http(s)://<base>/setup?token=<raw>` with a Copy button
+   - Countdown timer (live JS) showing time-to-expiry
+   - Warning: "This is the only time you'll see this link. If you lose it, regenerate from the user edit page."
+   - "Done" button → `/settings/users`
+
+The raw token is **never persisted** server-side. Lost tokens require regeneration.
+
+### Setup landing page (public, no auth required)
+
+1. User clicks the link, lands on `/setup?token=<raw>`
+2. Server hashes the token, looks up `user_setup_tokens` row, validates `expires_at > now`
+3. On invalid / expired: render an error page with a "Contact your administrator" message. Audit: `user.setup_token.expired` (no actor).
+4. On valid: render a password-set form: `new password + confirm`. Submit:
+   - Validates password meets policy (min 12 chars, no other constraints in v1 — same as bootstrap path)
+   - Hashes via `auth.HashPassword` (existing helper)
+   - Updates `users.password_hash`, sets `must_change_password = 0`
+   - Deletes the `user_setup_tokens` row (single-use)
+   - Logs the user in via the existing session helper
+   - Audit: `user.setup_completed`, payload `{"user_id": "..."}`
+   - Redirect to `/`
+
+### Regenerate setup link (admin)
+
+`/settings/users/{id}/edit` shows a "Regenerate setup link" button when `must_change_password = 1`. Clicking it:
+
+1. Generates a new token + hash, INSERT OR REPLACE on `user_setup_tokens`
+2. Returns the admin to the same one-time link page as the add-user flow
+3. Audit: `user.setup_token.regenerated`
+
+### Cleanup
+
+Expired tokens linger in the DB until cleaned. Add a cheap sweep on the existing maintenance ticker: `DELETE FROM user_setup_tokens WHERE expires_at < ?`. Runs at the same cadence as the alert engine tick (60s). No new ticker needed.
+
+## Self-service password change
+
+`/settings/account`
+
+- Accessible to every authenticated user (any role)
+- Form: `current password + new password + confirm`
+- Server validates current password (re-uses login bcrypt comparison), updates hash, audits `user.password_changed`
+- Special case: if `must_change_password = 1`, the current-password field is hidden / not required (covers the legacy "admin reset password" path if we ever add one — current setup-token path doesn't use this)
+
+The bootstrap user's password change uses this same page (no special case for "first admin").
+
+## User list / management UI
+
+### `/settings/users` (admin-only)
+
+```
+Settings · Users [3]
+─────────────────────────────────────────────────
+[ + Add user ]                       [ ] Show disabled
+
+USERNAME       EMAIL              ROLE      LAST LOGIN     STATUS
+alice          alice@example.com  admin     2 mins ago     enabled
+bob            —                  operator  3 days ago     enabled
+charlie        c@example.com      viewer    never          setup pending  ← if has open setup token
+diane          d@example.com      operator  1 month ago    disabled       ← only when "Show disabled"
+
+Actions per row: Edit · (Re-enable | Disable)
+```
+
+- "setup pending" badge for users with `must_change_password=1` — clicking the row goes to edit, which surfaces the regenerate-link button prominently
+- "Show disabled" is a checkbox querystring filter (`?show_disabled=1`)
+- Sort columns: clickable like the audit log (username, role, last_login). Reuse the same pattern (server-side sort + URL builder + glyph)
+
+### `/settings/users/new` (admin-only)
+
+Single form: `username + email (optional) + role`. On submit → either landed on the setup-link page (success) or returned with an inline "username exists, re-enable existing?" panel (collision with disabled user) / red error (collision with enabled user).
+
+### `/settings/users/{id}/edit` (admin-only)
+
+- Display-only block: id, created_at, last_login_at, status
+- **Editable**: email, role
+- **Buttons**:
+  - "Regenerate setup link" — only when `must_change_password = 1`
+  - "Disable user" — flips `disabled_at`; rejected if last enabled admin (server-side check). Confirmation modal with typed name to confirm.
+  - "Re-enable user" — clears `disabled_at`. No confirmation.
+  - "Force logout" — separate from disable; just kills the session but keeps the user enabled. Useful for "I think Bob's session was hijacked" without locking him out.
+- Cancel / Save buttons at the bottom
+
+### `/settings/users/{id}/setup-link` (admin-only)
+
+Renders the one-time link with copy button + countdown. Shown after add-user and after regenerate. Reload of this URL after the token is consumed: 410 Gone with a clear message.
+
+### `/settings/account` (any authenticated)
+
+Self-service password change. Form-only page; no nav under Settings since most users will only see this one Settings page in v1.
+
+## API surface
+
+```
+GET    /api/users                        admin   — list (with ?show_disabled=1 filter)
+POST   /api/users                        admin   — create user, returns user_id + setup_url
+GET    /api/users/{id}                   admin   — read
+PATCH  /api/users/{id}                   admin   — update email, role
+POST   /api/users/{id}/disable           admin   — set disabled_at; rejects last-admin
+POST   /api/users/{id}/enable            admin   — clear disabled_at
+POST   /api/users/{id}/regenerate-setup  admin   — new token, returns setup_url
+POST   /api/users/{id}/force-logout      admin   — kill all sessions for this user
+
+POST   /api/account/password             any auth — self password change
+GET    /setup                            public — landing page (HTML form)
+POST   /setup                            public — submit new password
+```
+
+UI routes mirror the API but at `/settings/users/...`.
+
+## Last-admin self-protection
+
+Two operations that could lock everyone out are guarded:
+
+- **Disable user**: rejected if the user is admin AND there are no other enabled admins
+- **Demote admin to operator/viewer**: same check
+
+Server-side enforcement (single SELECT on `COUNT(*) FROM users WHERE role='admin' AND disabled_at IS NULL`). UI hint: edit page disables the role dropdown's non-admin options + disable button when the user is the last admin, with a tooltip explaining why.
+
+The bootstrap admin is just a regular admin row; this check covers it.
+
+## Audit actions
+
+New action strings introduced:
+
+- `user.created`
+- `user.updated` (email / role change)
+- `user.disabled`
+- `user.enabled`
+- `user.password_changed`
+- `user.setup_completed`
+- `user.setup_token.regenerated`
+- `user.setup_token.expired` (system-driven, on cleanup sweep)
+- `user.force_logout`
+
+All target_kind = `user`, target_id = the affected user's id. Existing payload conventions apply.
+
+## Ordering / dependencies
+
+Slices in approximate landing order (writing-plans will firm this up):
+
+1. **A. Schema** — migrations 0017 + 0018, `Role` helper updates, store API extensions (email, disabled_at, must_change_password, setup_token CRUD, lowercase username constraints)
+2. **B. RBAC middleware** — `requireRole` + `roleAtLeast`, route re-grouping in server.go, 403 rendering for HTML + JSON
+3. **C. Session re-validation** — extend the existing session middleware to re-read user state per request, kick disabled users
+4. **D. Setup-token flow** — `/setup` GET+POST, the one-time link page after add-user
+5. **E. User CRUD API** — handlers + handlers' tests
+6. **F. UI** — `/settings/users` list, add, edit, setup-link page, account page
+7. **G. Sweep** — Playwright walk through the full lifecycle (add → setup link → user signs in → admin disables → user gets kicked → admin re-enables → user signs back in)
+
+Each slice can land as its own commit on the branch. RBAC middleware (B) goes in *before* user CRUD so we don't ship an open `/api/users/*` even briefly.
+
+## Test strategy
+
+- **Store**: `Set/GetSetupToken`, `EnableUser`/`DisableUser`, last-admin guard, lowercase-username uniqueness, expired-token cleanup
+- **HTTP middleware**: `roleAtLeast` truth table; viewer hitting an operator route returns 403; disabled user gets 401 mid-session
+- **Setup flow integration**: create user → fetch setup URL → land on `/setup?token=...` → POST password → user can log in → token row gone
+- **UI**: existing Playwright sweep pattern, screenshots into `_diag/p4-03-04-sweep/`
+
+## Out of scope (deferred)
+
+- **OIDC** (P4-05) — adds a parallel auth chain. This PR keeps the surface for it (role taxonomy, session middleware) but doesn't wire it.
+- **Email-the-setup-link** — explicitly deferred. Easy follow-up because the SMTP channel client from P3-06 is already there.
+- **Hard delete** — disable-only in v1; can add a typed-confirm "purge" later if it turns out to be needed.
+- **Password complexity / rotation policy** — current minimum (12 chars) and no rotation; tighten later if/when policy demands.
+- **Lockout on failed login** — a brute-force protection layer is its own task and orthogonal to RBAC.
+- **Audit on 403** — not in v1; revisit if compliance asks for it.
+
+## Risks / gotchas to watch
+
+- **Existing tests** that assume "any logged-in user can hit any endpoint" will break. Audit the test fixtures: most use `loginAsAdmin`, which is fine; any tests currently exercising specific operator/viewer paths need explicit role assignment. (Quick grep suggests there aren't many — bootstrap-only.)
+- **Bootstrap user normalisation** — the existing admin row's username is whatever it was set to at first run. The new lowercase-uniqueness index uses `LOWER(username)`, which makes the existing row implicitly lowercase-keyed for lookups. No data migration needed.
+- **Session middleware re-read cost** — one SELECT per authenticated request. SQLite WAL handles this fine at expected fleet sizes; if it ever shows up on a profile we add a small in-memory cache keyed by session id with a 30s TTL.
+- **403 vs 401 distinction** — make sure unauthenticated requests still get 401 (login redirect) and authenticated-but-insufficient get 403. The middleware should compose: auth-required first, role-required second.
+
+## Acceptance
+
+- [ ] An admin can add a user, copy the setup link, the new user can land on `/setup?token=...`, set a password, and reach `/`
+- [ ] An expired token (>1h) on `/setup?token=...` shows the "contact your administrator" page
+- [ ] Admin regenerates the link, old token is invalid, new token works
+- [ ] Operator user can trigger Run-now but cannot reach `/settings/users` (403) and the Users tab in Settings is hidden in their nav
+- [ ] Viewer user gets 403 on Run-now, 200 on dashboard / alerts / audit
+- [ ] Admin disables a user mid-session — the user's next request is 401 and they're redirected to login
+- [ ] Admin cannot disable themselves if they are the last enabled admin (server returns 409, UI button is greyed)
+- [ ] Self-service password change at `/settings/account` works for every role
+- [ ] All existing tests pass; new test suite covers role middleware, setup-token lifecycle, last-admin guard
+
+## Self-review notes
+
+- ✅ All sections concrete, no TBD / TODO
+- ✅ Schema migrations are column-level (CLAUDE.md compliance)
+- ✅ Audit action vocabulary listed in one place; no string typos to drift
+- ✅ Out-of-scope list explicit so reviewers can challenge what we *aren't* doing
+- ✅ Last-admin guard handled both server-side and UI-hinted
+- ✅ Token storage hashes the secret server-side; raw is shown to admin once and never again
+- ✅ Session re-validation cost noted with a fallback if it shows up on a profile

+# P4-05 — OIDC Login Design
+
+> **Date:** 2026-05-05
+> **Status:** brainstorm complete; ready for plan
+> **Closes:** P4-05 (OIDC login)
+
+## Goal
+
+Wire OpenID Connect authentication as a sign-in path alongside the existing local-user system, so a deployment that already has an IdP (Authelia, Authentik, Keycloak, Okta, Auth0, etc.) can use it for restic-manager logins.
+
+## Architecture
+
+OIDC sits on top of the local-user system rather than replacing it. The first time a user signs in via OIDC the server **just-in-time provisions** a local user row marked `auth_source='oidc'`, with role derived from the IdP's `roles` claim. Subsequent sign-ins look up the same row by stable `oidc_subject` and refresh role + email from the latest claims. Once the row exists it behaves like any other local user — admin can disable it, force-logout, see it in audit logs, etc. — except password-login is rejected because there's no password.
+
+The Authorization Code flow (with PKCE) is implemented against the discovered well-known config of a single configured issuer. Front-channel logout: clicking Sign out drops the local session + redirects the browser to the IdP's `end_session_endpoint` (when advertised). Back-channel logout deferred.
+
+## Locked decisions
+
+| Decision | Pick |
+|---|---|
+| User lifecycle | **B** — JIT-provision local rows on first OIDC login (`auth_source='oidc'`, `oidc_subject`) |
+| Role mapping config | **A** — YAML/env, claim name configurable (default `groups`, matching Authelia / Keycloak / Authentik), default = deny on no-match |
+| Username source | `preferred_username`, fallback to `email` |
+| Username collision with existing local user | **Refuse** with clear remediation message |
+| Provider config | **Single provider** — `providers:` array can come later |
+| Login page layout | SSO button **above** password form; password form labelled "or sign in with a local account" |
+| OIDC users + password login | **Disabled** — `auth_source='oidc'` rows have empty `password_hash`; password form rejects them |
+| Logout shape | **Front-channel only** — drop session + redirect to `end_session_endpoint` when advertised |
+| Role re-evaluation | **At login only** — claims read at the OIDC callback; admin can disable mid-session locally |
+
+## Schema changes
+
+Migration 0019 — `users` extensions for OIDC bookkeeping:
+
+```sql
+ALTER TABLE users ADD COLUMN auth_source TEXT NOT NULL DEFAULT 'local'
+  CHECK (auth_source IN ('local', 'oidc'));
+ALTER TABLE users ADD COLUMN oidc_subject TEXT;
+
+CREATE UNIQUE INDEX users_oidc_subject ON users(oidc_subject)
+  WHERE oidc_subject IS NOT NULL;
+```
+
+Both column-level ALTERs (CLAUDE.md preference). The unique partial index defends the JIT-lookup invariant (one row per IdP subject) without blocking multiple rows with NULL oidc_subject (the local users).
+
+## Configuration
+
+```yaml
+# server config — extend existing config struct
+oidc:
+  issuer:        https://auth.example.com    # well-known config discovered from this
+  client_id:     restic-manager
+  client_secret: ${RM_OIDC_CLIENT_SECRET}    # or via _FILE
+  display_name:  Authelia                    # button label "Sign in with <display_name>"; default "SSO"
+  scopes:        [openid, profile, email, groups]
+  role_claim:    groups                      # default if absent (matches Authelia / Keycloak / Authentik)
+  role_mapping:
+    rm-admins:    admin
+    rm-operators: operator
+    rm-viewers:   viewer
+  # Optional — auto-derived from BaseURL if absent.
+  redirect_url:  https://rm.example.com/auth/oidc/callback
+```
+
+Env-var overrides: `RM_OIDC_ISSUER`, `RM_OIDC_CLIENT_ID`, `RM_OIDC_CLIENT_SECRET`, `RM_OIDC_CLIENT_SECRET_FILE`. Mapping is YAML-only (env doesn't fit a multi-key string→string map cleanly).
+
+When `oidc.issuer` is empty or missing, OIDC is disabled (current behaviour). No restart-toggle UI; this is a deploy-time setting.
+
+## Auth flow
+
+### Login start
+
+`GET /auth/oidc/login` — only mounted when OIDC is configured.
+
+1. Generate `state` (32 random bytes, base64) and `code_verifier` (64 random bytes, base64); compute `code_challenge = base64(sha256(code_verifier))`.
+2. Store `(state, code_verifier, created_at)` in a new ephemeral table (or in memory with a 5-minute TTL — see "trade-off" below).
+3. Redirect to `<authorization_endpoint>?response_type=code&client_id=...&redirect_uri=...&scope=...&state=...&code_challenge=...&code_challenge_method=S256`.
+
+### Callback
+
+`GET /auth/oidc/callback?code=...&state=...` — also OIDC-only mount.
+
+1. Validate `state` against the stored value (one-shot — delete row on read). Reject if missing/expired/already used.
+2. Exchange `code` + `code_verifier` for tokens at `token_endpoint`.
+3. Validate the `id_token` JWT: signature against the JWKS endpoint, `iss`, `aud`, `exp`, `iat`, `nonce` (if used).
+4. Extract `sub`, `preferred_username`, `email`, and the configured `role_claim` (default `roles`).
+5. Pick username: `preferred_username` if non-empty, else `email`. Lowercase / trim per the existing local-user rules.
+6. Pick role: first match in `role_mapping` against the array of role-claim values. **No match → deny with a clear error page**, no row created.
+7. Look up user by `oidc_subject`. Three cases:
+   - **Found** — refresh `email`, `role`, `last_login_at`. Don't touch `username` (changing it would break audit trails; if the IdP changes the username, that's an operator concern). Log `user.oidc_login`.
+   - **Not found, username free** — INSERT row with `auth_source='oidc'`, `oidc_subject=<sub>`, `password_hash=''`, `must_change_password=0`. Log `user.created` with payload `{"auth_source":"oidc"}` + `user.oidc_login`.
+   - **Not found, username taken by a local user** — render an error page: "This OIDC user (`<sub>`) wants to sign in as `alice`, but a local user with that name already exists. Ask your administrator to either rename / remove the local user, or exclude this user from the OIDC mapping." 403, no row created. Log `user.oidc_login_blocked`.
+8. Drop a session cookie + `MarkUserLogin` (the existing helper).
+9. Redirect to `/`.
+
+### Logout
+
+`POST /logout` (existing handler) — augmented:
+
+1. Look up the session before deletion (we need the user row to know if they're an OIDC user).
+2. Delete the session as today.
+3. If the user is `auth_source='oidc'` AND the discovered `end_session_endpoint` is non-empty → 303 to `<end_session_endpoint>?id_token_hint=<id_token>&post_logout_redirect_uri=<base>/login`. Otherwise → existing 303 to `/login`.
+
+We need to keep the latest `id_token` per session to drive `id_token_hint`. Stash it in a new `sessions.id_token TEXT` column (one column-level ALTER on migration 0019 alongside the user columns), populated only for OIDC sessions.
+
+## State table
+
+Two reasonable shapes for the short-lived state used during the OAuth round-trip:
+
+- **In-memory map** with a 5-minute TTL sweeper. Simpler, but multi-process deployments lose it (no multi-process today, but Phase 5 OSS readiness might add).
+- **`oidc_state` table** — `(state_hash PK, code_verifier, created_at)`, swept on the same 60s alert-engine tick that already handles setup-token cleanup.
+
+I'll go with the **table**. Costs ~3 lines in the existing cleanup tick, behaves correctly under restarts, and survives a future scale-out. Migration 0019 includes:
+
+```sql
+CREATE TABLE oidc_state (
+  state_hash    TEXT PRIMARY KEY,    -- sha256(state) hex; raw state never persisted
+  code_verifier TEXT NOT NULL,
+  created_at    TEXT NOT NULL
+);
+CREATE INDEX oidc_state_created ON oidc_state(created_at);
+```
+
+## Login-page UI
+
+`/login` template branches based on `view.OIDCEnabled`:
+
+- **OIDC off** → current layout (just the password form).
+- **OIDC on** → an `Sign in with <provider name>` button at the top, then a faint divider line, then the existing password form labelled "Or sign in with a local account". Provider name comes from a new optional config `oidc.display_name` (defaults to "SSO").
+
+Failed-OIDC redirects (no role match, username collision, IdP error) land on `/login?oidc_error=<reason>` with a small banner above the buttons.
+
+## Audit actions
+
+New entries in the action vocabulary:
+
+- `user.oidc_login` (target_kind=user, target_id=user_id, payload `{"sub":"…"}`)
+- `user.oidc_login_blocked` (target_kind=user, target_id=oidc_subject when no row was created, payload `{"username":"…", "reason":"username_taken|no_role_match|other"}`)
+- `user.created` already exists; OIDC's first-time provisioning fires this with payload `{"auth_source":"oidc"}` so the audit log distinguishes admin-created from JIT-provisioned rows.
+
+## User-management UI changes
+
+Small additions, not new screens:
+
+- **Users list** — Status column adds a small `oidc` chip when `auth_source='oidc'` so admin can see at a glance which rows came from JIT-provisioning. Sortable by auth_source via the same sortable-headers pattern (lands as a small follow-up if anyone asks; out of scope for v1).
+- **Add user form** — disabled when OIDC is the only auth path, with a hint: "User provisioning is handled by your OIDC provider; users appear here on first sign-in." Configurable later via a `oidc.disable_local_users` flag if that becomes a real ask. Out of scope for v1; both paths stay open.
+- **Edit user form** — when `auth_source='oidc'`:
+  - Username field disabled (changing it would just be undone on next OIDC login)
+  - Role dropdown disabled, with a hint: "Role is managed by your OIDC provider's `roles` claim mapping. Edit the mapping in server config to change."
+  - Email field disabled (refreshed from IdP on each login)
+  - **Disable / Enable / Force logout** still work — disabling an OIDC user kicks their session and rejects future OIDC logins ("user disabled by administrator")
+  - **Regenerate setup link** hidden — there's no setup token for OIDC users
+- **Login UI** — password form rejects users with `auth_source='oidc'` ("This account uses single sign-on. Click the SSO button above.")
+
+## Middleware / handler changes
+
+- **Routes**: new public-band entries `GET /auth/oidc/login`, `GET /auth/oidc/callback`. Skipped entirely when OIDC isn't configured (`s.deps.OIDC == nil`).
+- **Logout handler** augmented to fetch the user row + decide between local logout (303 → `/login`) and OIDC logout (303 → `end_session_endpoint`).
+- **Login handler** rejects `auth_source='oidc'` users with the SSO-prompt error.
+- **Last-admin guard** — already covers OIDC users naturally because they live in the `users` table. The role-from-claims path could create a "every admin gets demoted to operator" situation if the IdP's claim mapping is wrong; the guard rejects that demotion at the moment it'd be applied (returns the user to the login page with `oidc_error=role_change_blocked` and audit entry; admin must fix the mapping or promote a local admin first).
+
+## Implementation outline
+
+1. **Schema** — migration 0019 (users.auth_source + oidc_subject, sessions.id_token, oidc_state table)
+2. **Config** — extend `internal/server/config` with the OIDC block + env-var overrides; load JWKS lazily
+3. **Discovery + JWKS** — small helper that fetches `<issuer>/.well-known/openid-configuration` once at startup, caches `authorization_endpoint`, `token_endpoint`, `end_session_endpoint`, `jwks_uri`. JWKS refreshed on first failed verification.
+4. **Login start handler** — `/auth/oidc/login`
+5. **Callback handler** — `/auth/oidc/callback`, with the four claim-resolution branches
+6. **Logout handler augmentation** — branch on `auth_source`
+7. **Login form rejection** — local-user password form rejects OIDC accounts
+8. **State cleanup** — extend the alert engine's existing cleanup tick
+9. **UI** — `oidc` chip on users list, disabled fields on edit-form for OIDC users, login page SSO button + error banner
+10. **Tests** — config parse tests; happy-path callback test using a fake IdP (httptest server with a hand-rolled discovery doc + JWKS); username-collision test; no-role-match test; logout test
+11. **Sweep** — full Playwright walk against an actual IdP (Authelia in a Docker container) — admin gets in via OIDC, role mapping works, logout redirects through IdP, OIDC user can't password-login
+
+## Test strategy
+
+The IdP is the hard part to test cleanly. Two layers:
+
+- **Unit / integration tests** use a stub OIDC provider built into the test harness — `httptest.Server` exposing `.well-known/openid-configuration`, a token endpoint that signs minted JWTs with a test ECDSA key, and a JWKS endpoint serving the public key. This covers every code path without a real IdP. Pattern: each test mints its own claims and runs the callback against the stub.
+- **Smoke env** runs against a real Authelia container (existing `compose.smoke.yaml`-style file or one-liner `docker run`) for the final sweep — confirms the discovery doc isn't being misread, real JWT verification works, real `end_session_endpoint` redirect works.
+
+## Out of scope (deferred)
+
+- **Multi-provider** support (`providers:` array)
+- **Back-channel logout** (RFC 8138) — schema isn't blocked from adding it later
+- **UI-driven role mapping** (config-only in v1)
+- **Refresh tokens / mid-session role re-evaluation** — login-only refresh in v1
+- **`oidc.disable_local_users`** flag — both paths stay open in v1
+- **OIDC user dashboard chip / badges** beyond the small `oidc` indicator on the users list
+- **Per-user "auth source" filter on the users list** — sortable headers cover most of the use case
+
+## Risks / gotchas
+
+- **JWKS key rotation** — refresh on first failed verification is the standard fix; document the cache TTL (1h) in the config block.
+- **Clock skew** — accept `iat`/`exp` with a 60s leeway; matches what most OIDC libraries do.
+- **End-session 404 / not advertised** — degrade gracefully; just drop the session and 303 to `/login`. Don't 500 the logout because the IdP doesn't implement RP-initiated logout.
+- **Username changes at the IdP** — silently keep the local username (matches our locked decision: subject is the stable key, username is display-only). Document.
+- **Role claim is sometimes a string, sometimes an array, sometimes a comma-separated string** depending on IdP — normalise into `[]string` before mapping. Authelia/Keycloak emit arrays; some custom setups emit strings; handle both.
+- **Authelia `sub` is an opaque UUID, not the username** (Authelia 4.39+ default for new clients). Don't assume `sub` is human-readable; it's stable but display value is `preferred_username` or `email`. The locked design already keys lookups on `sub` and uses `preferred_username` for the display username, so this is just a correctness note.
+- **`end_session_endpoint` may not be published** (Authelia doesn't advertise it for many configs). The locked logout flow already degrades to "drop session + redirect to /login" when the discovery doc lacks it; no extra config needed.
+- **Password-form bypass for OIDC users via /api/auth/login (JSON)** — same rejection rule applies, not just the HTML form.
+
+## Acceptance
+
+- [ ] An OIDC user with `roles: ["rm-admins"]` can sign in, becomes an admin, is visible in `/settings/users` with an `oidc` chip
+- [ ] Same user signing in again resolves to the same row (no duplicate)
+- [ ] Same user with `roles: ["something-else"]` is denied, lands on `/login?oidc_error=no_role_match` with a banner, no row created
+- [ ] OIDC user can't password-login through `/login` or `/api/auth/login`
+- [ ] Admin disables an OIDC user → next OIDC login is rejected, existing session bounced (existing disable-mid-session)
+- [ ] Sign out as an OIDC user → 303 to IdP's end-session URL (when advertised); no end-session URL → 303 to `/login`
+- [ ] OIDC config absent → password login works exactly as today (zero behavioural change)
+- [ ] Username collision: a local `alice` exists, OIDC user with `preferred_username=alice` and a different `sub` → blocked at sign-in with the clear error page
+- [ ] Last-admin guard refuses to demote the only enabled admin even if the IdP's role mapping says otherwise
+- [ ] All existing tests pass; new test suite covers the four claim-resolution branches and logout

+# P5-03 — Docker-only release path
+
+**Status:** approved 2026-05-05. Pivots P5-03 away from `goreleaser` +
+binary archives toward a single Docker image as the only public
+deliverable.
+
+## Goal
+
+One artifact per tag: the `restic-manager` server image, multi-arch
+(linux amd64 + arm64), published to the Gitea container registry of
+this self-hosted instance. The image bakes in cross-compiled agent
+binaries (linux amd64, linux arm64, windows amd64), the install
+scripts, and the systemd unit at a read-only image path. The running
+server distributes those agents and scripts via its existing
+`/agent/binary` and `/install/*` endpoints; operators on N hosts never
+download a release artifact directly.
+
+Source builds via `make build` remain a first-class path for anyone
+who wants binaries.
+
+## Non-goals
+
+- Standalone binary archives (`.tar.gz`, `.zip`) on the release page.
+- darwin / windows-arm64 agent targets — neither is service-tested.
+- `goreleaser`. Not used.
+- `cosign`, `SBOM`, `in-toto`, `minisign`. Re-promote when we ship
+  binaries outside an image (Phase 6 candidate).
+- GHCR / GitHub mirror. Single source of truth = Gitea.
+
+## Decisions captured (with one-line rationale)
+
+| ID | Decision | Why |
+|----|----------|-----|
+| D1 | One artifact: server Docker image | Architecture already routes agent distribution through the server (`/agent/binary`); release surface should mirror that. |
+| D2 | Trigger: `tag-push` (`v*.*.*`) **plus** `workflow_dispatch` | Tag for real cuts; dispatch for snapshot iteration without polluting tag history. |
+| D3 | Build matrix: linux amd64+arm64 server image; agent cross-compiles for linux amd64+arm64+windows amd64 | Mirrors the existing CI build matrix; nothing ships that hasn't been service-tested. |
+| D4 | Image-baked, separate path (`/opt/restic-manager/dist/`); HTTP handler reads `<DataDir>/...` first, falls back to `/opt/...` | Volume stays purely operator state; image content is immutable per tag; eliminates the smoke-env "stale agent" footgun in production. |
+| D5 | Tag fan-out: `vX.Y.Z`, `X.Y`, `X`, `latest` — but `latest` is held back until `v1.0.0` | Standard rolling-minor pattern; pre-1.0 forces explicit pinning. |
+| D6 | Snapshot tag: `:snapshot-<shortsha>`, never moves `latest` | Operator can never accidentally pull an unblessed build. |
+| D7 | Version embedding via `-ldflags`: `main.version`, `main.commit`, `main.date` on both `cmd/server` and `cmd/agent` | Server already had `version`; add `commit`/`date` to both for parity and traceability. |
+| D8 | Registry: Gitea container registry on this instance, under `<host>/<owner>/restic-manager` | One source of truth, no external creds. |
+| D9 | Integrity: a `SHA256SUMS` file + the manifest digest in the release notes; nothing else | Image is the unit of trust; pull-by-digest is the verification primitive. |
+| D10 | P1-31 (signed binaries) stays deferred | Re-promote the day we ship binaries outside an image. |
+
+## Image layout
+
+Multi-stage Dockerfile (extends today's `deploy/Dockerfile.server`):
+
+```
+build stage (golang:1.25-alpine):
+    cross-compile cmd/server for $TARGETARCH (linux)
+    cross-compile cmd/agent for linux/amd64
+    cross-compile cmd/agent for linux/arm64
+    cross-compile cmd/agent for windows/amd64
+    (CGO_ENABLED=0 throughout — pure-Go SQLite)
+
+final stage (gcr.io/distroless/static-debian12:nonroot):
+    /usr/local/bin/restic-manager-server                   (matches image arch)
+    /opt/restic-manager/dist/agent-binaries/
+        restic-manager-agent-linux-amd64
+        restic-manager-agent-linux-arm64
+        restic-manager-agent-windows-amd64.exe
+    /opt/restic-manager/dist/install/
+        install.sh
+        install.ps1
+        restic-manager-agent.service
+```
+
+`/opt/restic-manager/dist/` is owned by `root:root`, mode `0755` for
+directories, `0755` for `install.sh` (script must be executable when
+the install path uses `curl ... | sh` semantics) and `0644` for the
+unit file and `install.ps1`. The agent binaries are mode `0755`.
+
+`<DataDir>` keeps holding only operator state: `restic-manager.db`,
+`secret.key`, `secrets.enc`, `audit/`, `tls/`. Nothing the image
+owns gets written into the volume.
+
+## Server-side handler change
+
+`internal/server/http/agent_assets.go` today reads from
+`<DataDir>/agent-binaries/<name>` and `<DataDir>/install/<name>`.
+
+Change: if the file isn't present in `<DataDir>`, fall back to
+`/opt/restic-manager/dist/<subpath>/<name>`. The fallback path is a
+new server-config field defaulted to `/opt/restic-manager/dist`,
+overridable via `RM_BUNDLED_ASSETS_DIR` for tests and source-build
+deployments. If neither path resolves, return 404 (existing
+`binary_not_published` / `not_found` body unchanged).
+
+This means:
+- A fresh container without any operator-staged overrides serves the
+  baked-in agents. No first-run setup needed.
+- An operator can still drop a custom-built agent into
+  `<DataDir>/agent-binaries/` to override the image's copy (handy for
+  pre-release agent testing without rebuilding the server image).
+- Source-build dev (`bin/restic-manager-server` running out of the
+  working tree) still works exactly as today — the fallback dir is
+  configurable, and the `<DataDir>` path remains the primary lookup.
+
+Tests cover four cases: (a) DataDir hit, (b) fallback hit, (c) DataDir
+hit shadows fallback, (d) neither — 404.
+
+## Versioning
+
+Both binaries grow `commit` and `date` ldflag-targets next to the
+existing `version`:
+
+```go
+var (
+    version = "dev"
+    commit  = "none"
+    date    = "unknown"
+)
+```
+
+Dockerfile gains `ARG VERSION`, `ARG COMMIT`, `ARG DATE`, all
+`""`-defaulted; the `go build` line passes them via `-ldflags`. The
+release workflow fills them from `${{ gitea.ref_name }}`,
+`${{ gitea.sha }}`, and a UTC ISO-8601 timestamp.
+
+Snapshot builds (workflow_dispatch) compute
+`VERSION=0.0.0-snapshot-${SHORTSHA}` and tag the image as
+`:snapshot-${SHORTSHA}` only. They never touch `latest` or any
+`vX.Y.Z` tag.
+
+## Workflow (`.gitea/workflows/release.yml`)
+
+```yaml
+name: Release
+
+on:
+  push:
+    tags: ['v[0-9]+.[0-9]+.[0-9]+']
+  workflow_dispatch:
+
+env:
+  IMAGE: gitea.dcglab.co.uk/${{ gitea.repository }}
+
+jobs:
+  image:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: docker/setup-qemu-action@v3
+      - uses: docker/setup-buildx-action@v3
+      - uses: docker/login-action@v3

+      - name: compute tags
+        id: meta
+        run: |
+          # tag-push  → :vX.Y.Z, :X.Y, :X (only :latest if X >= 1)
+          # dispatch  → :snapshot-<shortsha>
+          ...
+      - uses: docker/build-push-action@v6
+        with:
+          context: .
+          file: deploy/Dockerfile.server

+          push: true
+          tags: ${{ steps.meta.outputs.tags }}
+          build-args: |
+            VERSION=${{ steps.meta.outputs.version }}
+            COMMIT=${{ gitea.sha }}
+            DATE=${{ steps.meta.outputs.date }}
+```
+
+The `compute tags` step:
+
+- For `push:tags`: extract `vMAJOR.MINOR.PATCH`. Always emit
+  `:vMAJOR.MINOR.PATCH`, `:MAJOR.MINOR`, `:MAJOR`. Emit `:latest`
+  only when `MAJOR >= 1`.
+- For `workflow_dispatch`: emit `:snapshot-<shortsha>`. Nothing else.
+
+No release-asset upload step yet — the GHCR-equivalent registry push
+is the deliverable. A future iteration may attach a `SHA256SUMS` file
+to a Gitea release object once `tea release create` is wired in;
+that's not in scope for the first cut.
+
+## Tests / verification
+
+1. `go vet ./...` (CLAUDE.md rule, runs locally pre-commit).
+2. `go test ./internal/server/http/...` covers the new fallback
+   logic.
+3. Local manual smoke: `docker build -f deploy/Dockerfile.server .`
+   produces an image; `docker run --rm <image>` starts the server;
+   `curl http://127.0.0.1:8080/agent/binary?os=linux&arch=amd64`
+   serves bytes; `curl http://127.0.0.1:8080/install/install.sh`
+   serves the script.
+4. Release workflow itself is exercised on first tag-push; until
+   then, `workflow_dispatch` is the smoke test.
+
+## Operator-facing changes
+
+- `README.md` install snippet becomes
+  `docker run -v rm-data:/var/lib/restic-manager ...
+  gitea.dcglab.co.uk/<owner>/restic-manager:vX.Y.Z`. Pre-1.0
+  releases are pinned by exact tag; no `:latest` is published.
+- The CLAUDE.md "restage" block is dev-only (smoke env runs the
+  server out of `bin/`). Production users on the image never see
+  it.
+- `RM_BUNDLED_ASSETS_DIR` is documented in the server config
+  reference (defaults to `/opt/restic-manager/dist`).
+
+## Risks / footguns
+
+- **Image size growth.** Three agent binaries (~15-20 MB each
+  stripped) add ~50 MB. Acceptable; we're already shipping a
+  distroless server. Watch the trajectory once Phase 4 alerting is
+  in.
+- **Dockerfile cross-compile multiplies build time** on the runner.
+  Pure-Go means each leg is just a `go build`; total stage time
+  should stay under 60s on the self-hosted runner.
+- **`ARG VERSION` leakage.** The current Dockerfile already accepts
+  `ARG VERSION=dev`; we're tightening, not loosening.
+- **Operator overriding `<DataDir>/agent-binaries/<name>`** with a
+  stale binary will silently shadow the image's copy. Documented in
+  the server config reference; this is a feature (lets operators
+  hot-patch a pre-release agent) not a bug.
+
+## Out of scope (tracked for follow-up)
+

+# P6-01 + P6-02 — Agent self-update + fleet update
+
+Status: design approved 2026-05-06.
+Scope: P6-01 (agent self-update mechanism) and P6-02 (dashboard
+version reporting + fleet update UI). One spec, one branch — the
+two tasks are tightly coupled (P6-02 is the operator surface for
+the mechanism P6-01 ships).
+
+## 1. Background
+
+P5-03 pivoted release distribution to a single multi-arch server
+Docker image, with cross-compiled agent binaries baked under
+`/opt/restic-manager/dist/agent-binaries/` and served via
+`GET /agent/binary?os=…&arch=…`. The plumbing already does
+dual-path lookup: `<DataDir>/agent-binaries/<name>` overrides the
+image-baked copy, so an operator can hot-patch a pre-release agent
+without rebuilding the image.
+
+That makes the server the natural distribution point for agent
+upgrades. "Update agent" collapses to "re-fetch from your own
+server" — no apt repo, no Chocolatey, no third-party signing infra,
+and version pinning is automatic because the server only ever
+serves the agent that matches its own release.
+
+This spec wires up the update mechanism end-to-end and the
+operator surface that drives it.
+
+## 2. Decisions
+
+| # | Decision | Rationale |
+|---|----------|-----------|
+| 1 | Operator-driven only — no auto-update | Matches the rest of the app's job-dispatch model; avoids "bad release upgrades every host instantly"; auto-update can be added later as a setting flip if asked |
+| 2 | Linux: just exit, let systemd restart. Windows: detached helper script. | Linux supports rename-while-open; Windows holds an exclusive lock on the running .exe |
+| 3 | M1 (keep `agent.old` on disk) + M2 (rolling fleet update with halt-on-fail). Skip M3 (auto-rollback watchdog). | M1 is ~5 lines, M2 falls naturally out of P6-02's UI, M3 is a lot of plumbing for "shipped a binary that doesn't start" |
+| 4 | Skip sha256 digest verification for v1 | TLS already covers the corruption-in-transit threat; image-tampering is image-build's problem, not the agent's |
+| 5 | Exact string version match for "out of date" | With server-bundled binaries there's exactly one canonical version per server image — anything else is out of date by definition |
+| 6 | WS envelope only, no `restic-manager-agent update` CLI subcommand | YAGNI; no concrete consumer; the underlying logic is reusable when one appears |
+
+## 3. Wire protocol
+
+### 3.1 Server → agent: `command.update`
+
+```
+{
+  "type": "command.update",
+  "id": "<envelope id>",
+  "payload": {
+    "job_id": "<ulid>"
+  }
+}
+```
+
+No `os` / `arch` / `version` in the payload — the agent already
+knows its own build target and fetches from its configured server
+URL via the existing `/agent/binary` handler. Including a target
+version would also tempt the agent into version-comparison logic;
+keep that on the server side.
+
+### 3.2 Job lifecycle (server-driven)
+
+The agent has limited ability to report on its own restart, so the
+job state machine lives on the server:
+
+- **queued → running** when the envelope is dispatched.
+- **running → succeeded** when the agent re-hellos with
+  `agent_version == server.Version` after dispatch and within
+  the timeout. Audit `host.update_succeeded`.
+- **running → failed (timeout)** if 90 seconds pass without a
+  hello carrying the matching version. Audit `host.update_failed`.
+  Raise alert kind `update_failed` (reuses P3-05 alert engine).
+  This single transition covers both the "agent never came back
+  at all" case and the "agent came back at the wrong version"
+  case — see §6.2 for why we don't transition immediately on a
+  mismatched hello.
+
+Migration 0021 widens the `jobs.kind` CHECK constraint to include
+`update`. Same column-level pattern as 0012 (where 0012 added
+`restore` and `diff`).
+
+## 4. Agent-side execution
+
+Lives in `internal/agent/updater`, build-tag split:
+
+- `updater_unix.go` — Linux + any future POSIX target.
+- `updater_windows.go` — Windows-only, uses the helper-script
+  pattern.
+- `updater.go` — shared `Update(ctx, serverURL string) error`
+  interface and the HTTP fetch/streaming code (no platform deps).
+
+### 4.1 Linux flow
+
+1. Receive `command.update` from the WS dispatcher.
+2. Resolve own binary via `os.Executable()` and `filepath.Abs`.
+   Refuse if the resolved path is `/proc/self/exe` or otherwise
+   not a real file (defence in depth — shouldn't happen under
+   systemd, but bail loudly if it does).
+3. `GET <server>/agent/binary?os=linux&arch=<runtime.GOARCH>`,
+   stream to `<binary>.new` in the same directory as the running
+   binary (same filesystem ⇒ atomic rename).
+4. fsync the file, `os.Chmod(0755)`.
+5. Copy current binary to `<binary>.old` (overwrite if it
+   exists). M1 — one-revision rollback target.
+6. `os.Rename(<binary>.new, <binary>)`.
+7. Close the WS connection cleanly (sends close frame so the
+   server transitions the connection to `disconnected` rather
+   than waiting for the heartbeat-miss sweep).
+8. `os.Exit(0)`. Systemd's `Restart=always` (already in the unit)
+   brings up the new binary within seconds.
+
+### 4.2 Windows flow
+
+The .exe is exclusively locked by the OS while running, so steps
+5–6 above can't happen in-process. Use a detached helper:
+
+1. Steps 1–4 the same — fetch into `<binary>.exe.new`, fsync.
+2. Write `update.cmd` to a tmp path with the orchestration:
+   ```
+   timeout /t 3 /nobreak >nul
+   copy /Y "<binary>.exe" "<binary>.exe.old"
+   sc stop restic-manager-agent
+   :wait
+   sc query restic-manager-agent | find "STOPPED" >nul
+   if errorlevel 1 (timeout /t 1 /nobreak >nul & goto wait)
+   move /Y "<binary>.exe.new" "<binary>.exe"
+   sc start restic-manager-agent
+   del "%~f0"
+   ```
+3. `CreateProcess` it detached
+   (`DETACHED_PROCESS | CREATE_NO_WINDOW`, no parent handles).
+4. Close WS, `os.Exit(0)`. SCM sees clean stop and waits — does
+   *not* try to restart, because `sc stop` is the helper's job,
+   not a crash. (`Restart=always` semantics differ between
+   systemd and SCM. SCM treats clean-exit-after-stop as
+   intentional and does not auto-restart; only crashes restart.
+   That's why the helper script needs the explicit `sc start`
+   at the end.)
+
+### 4.3 Service-user assumption
+
+Both Linux (`User=root` per the existing unit) and Windows
+(`LocalSystem` by default) can write the binary path directly. If
+the agent ever moves to a non-root service user, the updater
+breaks — would need either a setuid helper or an out-of-process
+update service. Add a `// NOTE:` comment in the updater package
+flagging this; not a v1 blocker.
+
+## 5. Server build version
+
+New package `internal/version` exposing two constants:
+
+```
+package version
+
+var (
+    Version = "dev"
+    Commit  = ""
+)
+```
+
+Wired via `-ldflags` in the Makefile:
+
+```
+GO_LDFLAGS = -X gitea.dcglab.co.uk/steve/restic-manager/internal/version.Version=$(VERSION) \
+             -X gitea.dcglab.co.uk/steve/restic-manager/internal/version.Commit=$(COMMIT)
+
+VERSION := $(shell git describe --tags --always --dirty)
+COMMIT  := $(shell git rev-parse --short HEAD)
+```
+
+Both `cmd/server` and `cmd/agent` link the same package, so an
+agent's `agent_version` (sent in the hello payload, already wired
+since P1-11) is comparable byte-for-byte to the server's
+`version.Version`.
+
+`make build` already does what's needed for source builds. The
+Phase 2 work in this spec is the Docker release path — confirm
+during plan execution that `.gitea/workflows/release.yml` passes
+`VERSION` and `COMMIT` into the Docker `--build-arg` chain so the
+in-image binaries embed the same string the image is tagged with.
+If not, add the wiring.
+
+Dirty/dev builds (`v1.2.3-dirty`) won't match clean server builds,
+so every dev environment will show every host as out-of-date. This
+is acceptable — the chip is a noop in dev, real ops always run
+tagged builds.
+
+A new `GET /api/version` endpoint returns
+`{"version": "...", "commit": "..."}`. Used by the dashboard
+header tile and by `/settings/fleet-update`. Public-band — exposes
+no secrets, lets the install scripts surface it too.
+
+## 6. P6-01 server endpoints
+
+### 6.1 `POST /api/hosts/{id}/update`
+
+Admin-only. Refuses (with structured error code) when:
+
+- Host is offline (`host_offline`).
+- Host's `agent_version == server.Version` (`already_up_to_date`).
+- An update job for this host is already running (`update_in_progress`).
+
+Happy path: creates `jobs` row with `kind=update`, dispatches
+`command.update` envelope, audit-logs `host.update_dispatched`,
+returns `{"job_id": "..."}`.
+
+UI form-post variant on `/hosts/{id}/update` returns
+`HX-Redirect` to the live job log.
+
+### 6.2 Hello handler integration
+
+The existing `onAgentHello` (P1-11) already upserts
+`agent_version`. Extend it: after the upsert, look for any
+`update` job for this host with `status='running'`. If one
+exists:
+
+- `agent_version == server.Version` → mark job `succeeded`,
+  audit `host.update_succeeded`.
+- `agent_version != server.Version` → leave the job running so
+  the timeout path catches it as a rollback failure (don't fail
+  immediately — gives the agent one chance to come back, restart,
+  hello again with the right version).
+
+Adds a small in-memory map of pending updates so the timeout
+goroutine knows when to give up. Persisted state lives in the
+`jobs` table; the in-memory map is just for the timer.
+
+## 7. P6-02 fleet update
+
+### 7.1 Schema
+
+Migration 0022, column-level adds only:
+
+```
+CREATE TABLE fleet_updates (
+  id              TEXT PRIMARY KEY,
+  started_at      TEXT NOT NULL,
+  started_by_user_id TEXT NOT NULL REFERENCES users(id),
+  target_version  TEXT NOT NULL,
+  status          TEXT NOT NULL CHECK (status IN ('running','completed','halted','cancelled')),
+  current_host_id TEXT REFERENCES hosts(id),
+  halted_reason   TEXT,
+  completed_at    TEXT
+);
+
+CREATE TABLE fleet_update_hosts (
+  fleet_update_id TEXT NOT NULL REFERENCES fleet_updates(id) ON DELETE CASCADE,
+  host_id         TEXT NOT NULL REFERENCES hosts(id) ON DELETE CASCADE,
+  status          TEXT NOT NULL CHECK (status IN ('pending','running','succeeded','failed','skipped')),
+  job_id          TEXT REFERENCES jobs(id),
+  failed_reason   TEXT,
+  PRIMARY KEY (fleet_update_id, host_id)
+);
+```
+
+### 7.2 Worker loop
+
+A single in-process goroutine — at most one fleet update may run
+at a time (enforced via a `sync.Mutex` + a precondition check on
+`POST /api/fleet/update`).
+
+```
+for each pending fleet_update_hosts row in dispatch order:
+    set fleet_updates.current_host_id = row.host_id
+    set fleet_update_hosts.status = 'running'
+    if host.agent_version == server.Version:
+        # Already updated since we built the list — skip.
+        set status = 'skipped'; continue
+    if !host.online:
+        # Offline since we built the list — halt.
+        halt(reason="host went offline")
+        return
+    dispatch_update_for_host(host)  # reuses 6.1 logic
+    wait_up_to_90s_for_hello_with_matching_version()
+    if matched:
+        set status = 'succeeded'; continue
+    else:
+        set status = 'failed', failed_reason = "..."
+        halt(reason="update failed on host X")
+        return
+set fleet_updates.status = 'completed', completed_at = now
+```
+
+Halt: set `fleet_updates.status = 'halted'`, raise an alert kind
+`fleet_update_halted`, audit `fleet.update_halted` with the host
+id and reason. Subsequent hosts stay `pending` so the operator can
+see what was queued and decide whether to resume (resume = start a
+new fleet update with the still-out-of-date subset).
+
+Cancel: admin-only `POST /api/fleet-updates/{id}/cancel`. Sets
+`status='cancelled'`. The currently-dispatched host's update job
+keeps running (the agent is already mid-restart) — cancel only
+prevents the *next* host from being picked. Audit
+`fleet.update_cancelled`.
+
+### 7.3 UI surfaces
+
+**Per-host chip (host_row partial + host detail chrome):**
+
+`out of date · v1.2.2 → v1.2.3` — amber-accented, mirrors `.tag`
+token shape. Only rendered when:
+
+```
+host.agent_version != "" && host.agent_version != server.Version
+```
+
+Empty `agent_version` (host enrolled but never connected) renders
+nothing rather than "out of date" — we don't know what version
+they have.
+
+**Dashboard summary tile:**
+
+The hero strip already has tiles. Add an "Updates" tile:
+`N hosts behind` linking to `/?updates=behind` (extends NS-04's
+filter machinery — adds an `updates` query param alongside
+`status`/`repo_status`/`tag`). Hidden when N == 0.
+
+**Per-host Update button on `/hosts/{id}`:**
+
+Right-rail, admin-only. Disabled with hover tooltip when host
+offline / already up to date / update in progress. POSTs to
+`/hosts/{id}/update`, `HX-Redirect` to the live job log.
+
+**Fleet update page `/settings/fleet-update`:**
+
+Admin-only. Two states:
+
+- **Idle**: lists out-of-date online hosts (table: hostname,
+  current version, target version, last seen). Big "Start rolling
+  update" button behind a typed-confirm dialog (operator types
+  the host count, e.g. `12`, to enable the button — same shape as
+  the host-delete confirm).
+- **Running/halted/completed**: shows the currently-active
+  fleet_update row + per-host progress list. Polls every 3s (htmx
+  trigger conditional on `document.visibilityState === 'visible'`,
+  same pattern as the alerts page). Renders:
+  ```
+  Updated 3/12 · currently updating <hostname>
+  Halted on <hostname>: <reason> · job log →
+  ```
+
+Audit actions: `fleet.update_started`, `fleet.update_completed`,
+`fleet.update_halted`, `fleet.update_cancelled`.
+
+### 7.4 Alert engine integration
+
+P3-05's alert engine already supports kind-based registration. Add
+two new kinds:
+
+- `update_failed` — per-host, raised on individual update failure.
+  Auto-resolves when the host re-hellos with the matching version.
+- `fleet_update_halted` — global, raised on fleet halt. Auto-resolves
+  when a subsequent fleet update completes successfully.
+
+## 8. RBAC
+
+| Endpoint | Role |
+|----------|------|
+| `POST /api/hosts/{id}/update` | admin |
+| `POST /api/fleet/update` | admin |
+| `POST /api/fleet-updates/{id}/cancel` | admin |
+| `GET /api/fleet-updates/{id}` | admin (status polling) |
+| `GET /api/version` | public |
+
+Operator and viewer see the "out of date" chip but no update
+buttons. Mirrors the existing pattern: read affordances are
+visible to all roles, write affordances are gated.
+
+## 9. Testing
+
+### 9.1 Unit
+
+- `internal/agent/updater`: fake-`/agent/binary` HTTP server +
+  tmp "running binary" file, assert post-state — binary swapped,
+  `.old` present, no leftover `.new`. Linux path only (Windows
+  helper covered by build-tag compile-only).
+- `internal/server/http`: `POST /api/hosts/{id}/update` happy
+  path, refuses-when-offline, refuses-when-up-to-date,
+  refuses-when-update-in-progress, RBAC enforcement, audit row
+  written.
+- Hello handler: agent reconnects with matching version after
+  `update` job dispatch → marks job `succeeded`, drops the
+  in-memory pending entry. Mismatched version → no-op (timeout
+  catches it).
+- Timeout path: synthetic `update` job + 90s elapsed →
+  marks `failed`, raises alert.
+- Fleet worker: table-driven over the loop's state machine —
+  success-then-success, success-then-timeout-halts,
+  cancel-mid-flight, no-online-out-of-date-hosts-completes-immediately,
+  host-disappears-from-list-mid-loop-skips.
+
+### 9.2 Smoke validation (per CLAUDE.md restage block)
+
+1. Build server + agent at version A. Restage. Enrol a host;
+   confirm `agent_version=A`.
+2. Bump version to B (`make build VERSION=B`), rebuild server
+   only, restart server. Dashboard shows host as out-of-date with
+   `A → B` chip. Updates tile reads "1 host behind".
+3. Rebuild agent at B, restage `<DataDir>/agent-binaries/`. Click
+   **Update agent** on host detail. Agent fetches, swaps, exits;
+   systemd restarts it; hello-back at B → job `succeeded`, chip
+   gone, tile clears.
+4. Rollback path: leave `<DataDir>/agent-binaries/` at A, server
+   at B, click Update — agent fetches A, swaps to A, restarts at
+   A; hello says A != B; server marks job `failed` after 90s with
+   reason "agent reconnected at version A, expected B".
+5. Fleet update: spin up two smoke hosts both out-of-date, fire
+   **Start rolling update**, watch progress page tick host 1 →
+   host 2 → completed.
+6. Halt path: replace one of the `<DataDir>/agent-binaries/`
+   files with `/bin/false`. Run fleet update. First host gets
+   broken binary, fails to come back up, fleet update halts at
+   host 1 after 90s, alert raised, host 2 left as `pending`.
+
+Step 6 validates M2 end-to-end — the rolling halt is the actual
+safety guarantee, not a nice-to-have.
+
+## 10. Out of scope
+
+- sha256 digest verification (deferred — see decision 4).
+- `restic-manager-agent update` CLI subcommand (deferred —
+  decision 6).
+- Auto-update (deferred — decision 1).
+- Auto-rollback watchdog M3 (deferred — decision 3).
+- Migrating the agent off `User=root` (separate hardening track).
+- Cross-version protocol-compatibility checks beyond the existing
+  `protocol_version` handshake (P1-11). If the new agent's
+  `protocol_version` is incompatible with the server, the
+  existing handshake rejects it; the update job will then
+  correctly time out and be marked failed.
+
+## 11. Migration plan
+
+1. `internal/version` package + Makefile ldflags wiring.
+2. Migration 0021 (jobs.kind widening) + 0022 (fleet_updates
+   tables).
+3. `internal/agent/updater` package, Linux first.
+4. WS envelope wiring + `command.update` dispatcher.
+5. `POST /api/hosts/{id}/update` + hello-handler integration +
+   timeout goroutine.
+6. UI: chip + per-host update button + dashboard tile + filter.
+7. Fleet update worker + page.
+8. Windows updater path.
+9. Alert engine kinds.
+10. Smoke validation per §9.2.
+
+Each step is independently testable; commits should land at each
+boundary so a failed Windows path (8) doesn't block the rest of
+the work.

+# P6-03 — Repo size trend graphs
+
+Sparkline on the dashboard host row + full chart on the host repo
+page, both showing repo growth over time. Closes the last
+operator-visibility gap in Phase 6 alongside Prometheus metrics
+(P6-04).
+
+## Goals
+
+- Operators can see at a glance whether a host's repo is growing,
+  stable, or shrinking, without leaving the dashboard.
+- A second screen on the repo page exposes the same data over a
+  longer window with a snapshot-count overlay so retention
+  behaviour can be eyeballed against size.
+- Zero new client-side dependencies; matches the existing
+  HTMX + server-rendered idiom used everywhere else in the UI.
+
+## Non-goals
+
+- No backfill of historical data. Trend lights up with whatever
+  the agents report from the day this ships.
+- No per-source-group breakdown — repo-level only.
+- No alerting on growth rate (dedicated to a future ticket if a
+  user asks).
+- No JSON API surface. Prometheus exposure is P6-04, separate.
+
+## Decisions taken in brainstorming
+
+- **Metrics:** `total_size_bytes` (sparkline + chart) and
+  `snapshot_count` (chart only). Raw size dropped as redundant.
+- **Cadence:** one row per `(host_id, UTC date)`, last-write-wins
+  per column. Bounded at ~365 rows/host/year regardless of job
+  frequency.
+- **Backfill:** none. Pure forward-fill from launch day.
+- **Rendering:** server-rendered inline SVG, no JS library.
+- **Spans:** sparkline fixed at 30 days; chart has `30d | 90d | 1y`
+  range selector, server-rendered swap.
+
+## Schema
+
+New migration `internal/store/migrations/0023_host_repo_stats_history.sql`:
+
+```sql
+CREATE TABLE host_repo_stats_history (
+  host_id           TEXT NOT NULL REFERENCES hosts(id) ON DELETE CASCADE,
+  day               TEXT NOT NULL,        -- 'YYYY-MM-DD' UTC
+  total_size_bytes  INTEGER,              -- nullable; partial patches don't overwrite
+  snapshot_count    INTEGER,              -- nullable
+  recorded_at       TEXT NOT NULL,        -- RFC3339Nano of last write touching this row
+  PRIMARY KEY (host_id, day)
+);
+CREATE INDEX host_repo_stats_history_host_day
+  ON host_repo_stats_history(host_id, day DESC);
+```
+
+FK cascade matches every other host-scoped table; deleting a host
+through `Store.DeleteHost` (NS-01) wipes its history automatically.
+
+## Write path
+
+Hook the existing `MsgRepoStats` handler in
+`internal/server/ws/handler.go` (around line 319). After the
+existing `UpsertHostRepoStats(ctx, hostID, patch)` call, append:
+
+```go
+day := time.Now().UTC().Format("2006-01-02")
+if err := deps.Store.UpsertHostRepoStatsHistory(ctx, hostID, day, patch); err != nil {
+    slog.Warn("ws: upsert host repo stats history", "host_id", hostID, "err", err)
+}
+```
+
+A history-write failure is logged and dropped — never blocks the
+main upsert. The partial-update contract that
+`UpsertHostRepoStats` already implements is preserved at the
+history layer:
+
+```sql
+INSERT INTO host_repo_stats_history (host_id, day, total_size_bytes, snapshot_count, recorded_at)
+VALUES (?, ?, ?, ?, ?)
+ON CONFLICT(host_id, day) DO UPDATE SET
+  total_size_bytes = COALESCE(excluded.total_size_bytes, host_repo_stats_history.total_size_bytes),
+  snapshot_count   = COALESCE(excluded.snapshot_count,   host_repo_stats_history.snapshot_count),
+  recorded_at      = excluded.recorded_at;
+```
+
+This is critical: the agent's prune handler in
+`internal/agent/runner/runner.go:318` emits a stats patch that
+only carries `LastPruneAt`. Without `COALESCE`, that prune ack
+would null out a `total_size_bytes` we'd already captured from a
+backup earlier the same day.
+
+## Read path
+
+Two new helpers in `internal/store/host_repo_stats_history.go`:
+
+```go
+type RepoStatsHistoryPoint struct {
+    Day            time.Time   // 00:00:00 UTC
+    TotalSizeBytes *int64
+    SnapshotCount  *int64
+}
+
+func (s *Store) ListHostRepoStatsHistory(
+    ctx context.Context, hostID string, since time.Time,
+) ([]RepoStatsHistoryPoint, error)
+```
+
+Returns rows ordered by `day` ascending where at least one metric
+is non-null. The renderer connects available points with a
+straight line — there is no explicit gap representation. A host
+that was offline for a week shows a single segment spanning the
+gap, which is the right visual: the repo state didn't change.
+
+## Rendering
+
+New package `internal/web/sparkline`. Pure Go, no template
+dependency:
+
+```go
+type Series struct {
+    Name   string
+    Points []float64    // nil-points represented as math.NaN
+    Stroke string       // CSS color
+}
+
+func RenderSparkline(points []float64, width, height int) template.HTML
+func RenderChart(series []Series, days []time.Time, opts ChartOpts) template.HTML
+```
+
+`RenderChart` produces a 600×220 SVG with:
+
+- Light horizontal gridlines (4 bands).
+- Two y-axes: bytes (left, blue) and count (right, amber). Each
+  series is normalised against its own axis.
+- X-axis labels at start, midpoint, and end of the window.
+- Per-point `<circle>` with a `<title>` for hover tooltips —
+  accessible by default, no JS.
+- Empty state: faint dashed baseline + centered "no data yet"
+  text.
+
+Sparkline is 80×20, single blue polyline, single `<title>` on the
+group element showing `"current → 30d ago"`.
+
+Two new partials:
+
+- `web/templates/partials/repo_size_sparkline.html`
+- `web/templates/partials/repo_size_chart.html`
+
+Both call into the renderer with the appropriate opts. No
+inline `<style>` — colours come from existing Tailwind palette
+classes already used elsewhere (`text-blue-500`, `text-amber-500`).
+
+## UI placement
+
+### Dashboard host row
+
+`web/templates/partials/host_row.html` gains one `<td>` between
+the existing "Repo size" cell and "Snapshots" cell. Width ≈ 88px.
+Cell renders the sparkline partial; if `len(points) < 2` the cell
+shows "—" centred (matches the existing no-data idiom for
+last-backup time in the same partial).
+
+The dashboard's existing 5-second htmx live-refresh
+(`hx-trigger="every 5s ..."` from NS-04) re-renders this cell
+along with the rest of the row. No extra polling.
+
+### Host repo page
+
+`web/templates/pages/host_repo.html` gains a "Trend" panel
+inserted between the existing summary panel and the maintenance
+panel. Panel contains:
+
+- Range pills `30d | 90d | 1y` (anchor links with
+  `hx-get="/hosts/{id}/repo/trend?range=…"` and
+  `hx-target="#repo-trend-chart" hx-swap="outerHTML"`).
+- The chart partial wrapped in `<div id="repo-trend-chart">`.
+- A small legend strip below the chart.
+
+## Endpoints
+
+- `GET /hosts/{id}/repo/trend?range=30d|90d|1y` — admin/operator,
+  htmx fragment, returns the chart partial. Auth reuses the
+  existing host-scoped middleware on the `/hosts/{id}` family.
+  Invalid `range` falls back to 30d.
+
+No new admin-only surface — anyone with read access to the host
+can see the trend.
+
+## Testing
+
+- `internal/store/host_repo_stats_history_test.go` — upsert
+  merges partial patches without nulling; ordering; since-day
+  filter; cascade on host delete.
+- `internal/web/sparkline/sparkline_test.go` — golden SVG files
+  for: empty input, single point, full 30-day series, mixed
+  null points. Goldens live under `testdata/`.
+- `internal/server/http/ui_repo_test.go` — trend panel renders
+  with seeded history; range selector swaps server-side; empty
+  state.
+- `internal/server/http/ui_dashboard_test.go` — host row sparkline
+  cell present and renders SVG when points exist, "—" when not.
+- Smoke after build: dashboard row shows sparkline once two days
+  of data exist; repo page chart toggles cleanly between ranges.
+
+## Migration / rollout
+
+- Schema migration is additive — no risk to existing tables.
+- Write path is best-effort; on schema issue the main repo-stats
+  upsert is unaffected.
+- No agent change required, so no fleet update needed.
+
+## Acceptance
+
+- After two days of operation, the dashboard sparkline shows a
+  visible line for any host that has run a backup or
+  maintenance op on both days.
+- Host repo page renders the trend panel with the snapshot-count
+  overlay; range selector switches view without a full page
+  reload.
+- `go test ./...` and `go vet ./...` clean.
+- Smoke env exercise: backup → sparkline updates; range pills
+  swap; FK cascade verified by deleting a host and checking the
+  history table.

-# Threat model
-
-A short, structured walkthrough of the assets restic-manager
-protects, the actors that interact with it, the attack surfaces
-exposed, and the mitigations in place. This document is written for
-operators considering a deployment and for contributors evaluating
-security-sensitive changes. It is **not** a formal certification —
-restic-manager has not been third-party audited.
-
-Last reviewed: **2026-05-09** (against v1.0.0).
-
----
-
-## 1. Assets
-
-In rough order of sensitivity:
-
-| Asset | Why it matters |
-|---|---|
-| **Restic repository passwords** | Decrypt every backup in the repo. Server holds them encrypted at rest; agents need plaintext at backup-time. |
-| **Repository URLs with embedded credentials** (e.g. `rest:https://user:pass@host/repo`) | Same as above — read access to the repo is leak-equivalent to the password. |
-| **Agent bearer tokens** | Long-lived credentials authenticating each agent → server WS. Compromise lets an attacker impersonate that host (push fake snapshots, ack fake schedule versions, exfiltrate repo creds the server pushes back). |
-| **Server session cookies** | Browser-side session for human operators. Compromise = full UI access at the user's role for the cookie's TTL (24h). |
-| **Database secret key** | Wraps every encrypted-at-rest field (repo creds, agent enrolment payloads). Loss of the file means decryptable backups; rotation requires re-pushing creds to every agent. |
-| **Bootstrap / setup tokens** | One-shot, time-limited; mint admin or invited-user accounts. |
-| **Audit log** | Tamper-evident record of admin actions; read-only via UI. |
-| **Backup data on the wire** | Restic itself encrypts on the agent before sending — see "out of scope". |
-
----
-
-## 2. Actors
-
-| Actor | Trust |
-|---|---|
-| **Anonymous internet** | Untrusted. Should not reach the server unless proxied behind auth (see deployment guide). |
-| **Authenticated viewer** | Read-only on hosts/jobs/alerts/audit. |
-| **Authenticated operator** | Add/remove hosts, edit schedules, run backups/restores, mint enrolment tokens, ack alerts. |
-| **Authenticated admin** | All of the above plus user management, role changes, fleet update controls, secret-key visibility (no — see below). |
-| **Agent** | Trusted to backup-and-report on its own host only. Cannot read other hosts' creds. Bearer-authenticated. |
-| **Restic backend (rest-server / S3 / B2 / etc.)** | Out of scope for this document — assumed to authenticate the credentials presented and not collude. |
-
----
-
-## 3. Attack surfaces and mitigations
-
-### 3.1 First-run bootstrap
-
-- **Surface**: `/bootstrap` UI + `/api/bootstrap` JSON endpoint.
-- **Risk**: race between server start and admin creation — an attacker who reaches the server first can claim admin.
-- **Mitigations**:
-  - Bootstrap token printed to stderr exactly once; held in memory, not persisted.
-  - The UI form on `/bootstrap` uses the in-memory token automatically (no token field for the operator to type or expose).
-  - Both surfaces self-disable the moment any user row exists (`CountUsers > 0`).
-  - Token is also blanked from process memory after success (defence in depth).
-- **Residual risk**: if an operator brings up the server on the public internet before reaching the bootstrap page, an attacker reaching `/bootstrap` first wins. **Recommendation**: bring the server up behind an existing trusted network or with the listener bound to `127.0.0.1` until first-run is complete.
-
-### 3.2 Local user accounts
-
-- **Surface**: `/login`, `/api/auth/login`.
-- **Mitigations**: Argon2id password hashing with per-deployment params; constant-time password compare; session-cookie minting via `crypto/rand`; session rows hash-only (raw token only in cookie).
-- **Rate limiting**: Currently not in place at the application layer — the project assumes a reverse proxy enforces login throttling. **Recommendation**: front the server with `caddy`/`nginx` rate-limit rules in production.
-- **Password policy**: 12-character minimum on bootstrap and user-setup paths; no maximum, no rotation, no history. Sufficient for self-hosted ops; tighten in policy if a deployment requires it.
-
-### 3.3 OIDC SSO
-
-- **Surface**: `/auth/oidc/*` — generic OIDC client, JIT user provisioning.
-- **Mitigations**: state + nonce per flow; role mapping is server-configured (claims trusted only to identify the user, not pick role); user-disabled gate runs after IdP success.
-- **Residual risk**: misconfigured role-mapping rules can promote any IdP user to admin. **Recommendation**: review `cfg.OIDC.RoleMappings` carefully.
-
-### 3.4 Agent enrolment
-
-- **Surface**: `/api/agents/enroll` (token-authenticated), `/api/agents/announce` (anonymous, then operator-approves).
-- **Mitigations**:
-  - Token path: one-shot, hashed at rest, 1h TTL; agent receives a fresh long-lived bearer in the response.
-  - Announce path: agent supplies an Ed25519 public key; operator sees a fingerprint to confirm out-of-band before accepting.
-  - Bearer tokens are SHA-256 hashed in the DB.
-- **Residual risk**: an attacker on the network between operator and target host who intercepts the install snippet can enrol *as* the target. The install script must be served over TLS in production (the docker-only deployment defaults to TLS-by-default; bare-metal deployers must configure their own).
-
-### 3.5 Agent → server WebSocket
-
-- **Surface**: persistent WS authenticated by agent bearer.
-- **Mitigations**: bearer is presented per-connection; server pins the agent fingerprint for the announce flow; messages are envelope-typed and rejected if shape-invalid.
-- **No payload-level signing** today — TLS is the integrity boundary. A man-in-the-middle with a valid cert chain could swap messages. **Recommendation**: pin the server cert via `RM_SERVER_CERT_PIN_SHA256` if running over a network you don't fully control.
-
-### 3.6 Repo credential lifecycle
-
-- Stored encrypted at rest under the AEAD secret key.
-- Pushed to the agent over the WS on hello, on creds change, and on demand.
-- Agent persists them encrypted (per-host secret key derived from a value known only to the agent).
-- Logged surfaces use `restic.RedactURL()` to strip `user:pass@` from URLs before they reach `slog`.
-- Plaintext form is constructed only at `exec.Command` time inside the agent, never stored on a struct field that could be slogged.
-
-### 3.7 Restore
-
-- Operators can restore to any path the agent (running as root) can write.
-- Cross-host restore (host A's snapshot → host C) is **deferred** — see F-01. The current single-host restore does not require granting any cross-host privileges.
-
-### 3.8 Audit log
-
-- Append-only writes from the application; SQLite enforces no schema-level immutability.
-- A compromise of the SQLite file (via OS-level access) can edit the audit log. **Recommendation**: ship audit entries to an append-only sink (syslog / Loki / Splunk) if tamper-evidence beyond the OS boundary is required.
-
-### 3.9 Self-update channel (P6)
-
-- Agents fetch new binaries via the WS transport from the server.
-- Binaries are signature-checked by the agent against a key embedded in the existing agent (see `internal/fleetupdate/`).
-- **Residual risk**: a server compromise lets the attacker push code to every agent (running as root). The signing-key compromise window is the same as the server compromise window because both live on the server. Splitting the signing key onto a separate signer is future work (not v1).
-
----
-
-## 4. Out of scope
-
-- **Restic itself** — its repository format, encryption, and backend protocol are upstream-trusted.
-- **The host OS** — root compromise of a host obviously compromises that host's backups.
-- **The backup destination** — restic-manager assumes the rest-server / object-store / SFTP target enforces its own auth.
-- **Side-channel attacks** on the server process (RAM dump, process tracing).
-- **Physical access** to the server's disk.
-

-## 5. Reporting
-
-Found something we missed? See `SECURITY.md` for the disclosure
-process. Coordinated disclosure preferred; the project is
-maintained by a small team and we'll respond as quickly as we
-reasonably can.

Reviewed against v1.0.0 surface; refresh on each tagged release.
-- [x] **X-05** Proper first-run onboarding UI. ✅ Landed: bootstrap form already lives at `/bootstrap` and `/login` redirects to it when no users exist (so an operator hitting the server in a browser is guided into setup automatically — the form takes username + password only, no token field needed because the server holds the in-memory token and applies it server-side). Improvements added here: at first-run startup the server now prints a clickable `$RM_BASE_URL/bootstrap` URL (or a fallback message when `RM_BASE_URL` is unset) alongside the existing one-shot token for headless `/api/bootstrap` use; the bootstrap form's password field shows an explicit "Minimum 12 characters" hint so the rule is visible before submission instead of failing on submit.
+- [ ] **X-04** Threat-model review at end of each phase
+- [ ] **X-05** Proper first-run onboarding UI: admin shouldn't need to `curl` `/api/bootstrap` by hand. Render the bootstrap form on the same login page (extra "setup token" field shown only while no admin user exists, hidden after); on submit POST to `/api/bootstrap`, then drop straight into a session. Surface the one-time token from the server log somewhere copy-able (or print a clickable URL with the token in the query string at first-run). Also: relax the 12-char password floor for the first-run path or document it in the form so `admin` doesn't silently fail validation.

 - [x] **NS-01** Admin-driven host deletion. ✅ Landed: store `DeleteHost` (FK cascade revokes the agent bearer along with everything else), admin-band `POST /hosts/{id}/delete`, danger-zone form on host detail with hostname-confirm, audit `host.deleted`, live WS connection closed pre-delete. Original scope below for reference. No UI or API surface today — once a host is enrolled the only way to remove it is hand-editing SQLite, which then cascades through schedules/jobs/snapshots/source-groups via the FK chain. Needs: store-level `DeleteHost` + cascade audit, admin-band `DELETE /api/hosts/{id}` and form-post variant, confirm-modal on the host-detail page, audit entry, and a decision on whether to also revoke the agent's bearer (recommend: yes, so a re-installed host comes back through the normal pending-host accept flow).
 - [x] **NS-02** Recoverable enrollment-token UX. ✅ Landed: `Store.ListOutstandingEnrollmentTokens` + `DeleteEnrollmentToken`; outstanding-tokens panel on the Add-host page (short hash, redacted repo URL, created/expires) with per-row Regenerate (revokes old hash, mints fresh raw token preserving repo creds + initial paths, 303s to `/hosts/pending/{newToken}`) and Revoke (delete + audit). Audit actions `enrollment_token.regenerated` / `enrollment_token.revoked`. Original scope below. Today `POST /hosts/new` mints a token and 303s to `/hosts/pending/{token}`; if the operator closes that tab the install snippet is lost and there's no UI surface to find it again — the row sits in `enrollment_tokens` until TTL expiry, invisible. Needs: store-level `ListOutstandingEnrollmentTokens` returning `(token_hash, created_at, expires_at, repo_url_redacted, initial_paths, attached_host_id_or_null)`; a small list section on the Add-host page (and/or Settings) showing outstanding tokens with created/expires-in and the redacted repo URL; admin-band `POST /api/enrollment-tokens/{id}/regenerate` (revokes the old hash, mints a fresh raw token, re-uses the original attachments — same pattern as the user-setup-token regenerate flow) and `POST /api/enrollment-tokens/{id}/revoke`. Choose regenerate over "show original token" because we only persist hashes, never raw tokens.
 - [x] **NS-03** Auto-init repo on first onboard, surface credential failures eagerly. ✅ Landed: migration 0020 adds `hosts.repo_status` (`unknown`/`ready`/`init_failed`) + `repo_status_error`; WS handler projects every init job's terminal state onto the host row (with idempotent "config file already exists" → ready); creds-save handlers (UI + JSON API) reset status to `unknown` and dispatch a fresh init when the agent is online; new `/hosts/{id}/repo/probe` retry endpoint and a status banner on the repo page. Remainder of original scope below. surface credential failures eagerly. Today the operator types repo URL + creds during Add-host and the credentials are pushed to the agent on connect, but no `restic init`/probe runs until the first scheduled job — so a typo in the password or a wrong URL goes undetected for hours/days, manifesting as a silent missed-backup. Wanted behaviour: when the host completes enrolment (or when an admin saves new repo creds), the server dispatches a one-shot probe job that runs `restic cat config` (cheap, repo-existence + creds-validity in one call). On `Is there already a config file? unable to open config file` → run `restic init`. On success → mark the host's repo as ready. On any other error (network, auth, fingerprint) → surface a panel-level error on the host detail page and audit the failure, leaving the host in an "init pending" state with a "Retry" button. Needs: a new `JobKind` (or piggyback on an existing one) for the probe, server-side state on the host row (`repo_status` enum: `unknown`/`ready`/`init_pending`/`init_failed`), UI panel that shows the state, and clear copy on the Add-host page so the operator knows the save isn't fire-and-forget.
-- [x] **NS-05** Drop redundant `actions/setup-go` from `.gitea/workflows/ci.yml`. ✅ Already gone — verified `.gitea/workflows/ci.yml` has zero `actions/setup-go@v5` invocations and no `GO_VERSION` env; the file's header comment now documents that the runner image (`gitea.dcglab.co.uk/steve/ci-runner-go`) is the single source of truth for the Go version. Closing as done; no further code change needed.
-- [x] **NS-06** Remove the permanently-disabled "Run backup now" button from `web/templates/partials/host_chrome.html`. ✅ Landed: dropped the disabled tombstone button from the host header action row; only "Edit credentials" + the ⋯ menu remain. Per-source-group Run-now on `/hosts/{id}/sources` is the only path now. No e2e change needed — `smoke.spec.ts` does not assert on host_chrome's button row.
-- [x] **NS-07** Relative timestamps go stale on long-open tabs. ✅ Landed: `formatRelTime` now wraps its label in `<time data-rel-ts=…>` and both layouts (`base.html`, `chromeless.html`) carry a small ticker that re-renders every 30s, so a page rendered an hour ago no longer keeps showing "2h ago" when the wall-clock truth is "3h ago". Covered by `funcs_test.go`. The bug: every relative label was computed once at server render and never updated client-side, so a job-detail page left open drifted further from reality the longer it sat.
-- [x] **NS-08** Always-On vs intermittent host mode. ✅ Landed: a host can now be marked not-always-on (laptop/workstation) so it stops generating offline-alert noise when it legitimately sleeps. Migration 0024 adds `hosts.always_on` (default 1 = today's 24×7 behaviour; intermittent is strictly opt-in). The alert engine suppresses `agent_offline` for intermittent hosts and instead wires up the previously-dead `stale_schedule` alert for them — raised at a 7-day global threshold when the host has an enabled schedule and a stale last backup, resolved on the next successful backup. A new server-side catch-up scheduler (`internal/server/http/catchup.go`) arms on agent hello and fires from the existing 30s pending-drain tick: ~60s after an intermittent host reconnects it dispatches a backup for any enabled schedule whose window elapsed while asleep (overdue = `cron.Next(lastBackup) <= now`, reusing the shared `cronParser`), guarded against firing when the host bounced offline, flipped to always-on, or already has a job running. Overdue is measured against the per-host `LastBackupAt` (exact for the common single-schedule laptop; a known coarseness for multi-cadence hosts, documented in code). Operator toggle via `POST /hosts/{id}/mode` (audited `host.mode_updated`), which also clears open offline/staleness alerts so the next sweep re-settles. UI: intermittent offline hosts render a calm grey `asleep · <relTime> · will catch up on return` state (new `.dot-asleep`) instead of red "offline"; a `24×7` chip shows only for always-on hosts; a "presence" inline toggle on the host header. Design + plan in `docs/specs/2026-06-15-always-on-host-mode-design.md` and `docs/plans/2026-06-15-always-on-host-mode.md`. Spec §2 (online/offline mechanics) deliberately left untouched. Out of scope for v1: per-host staleness thresholds, continuous (non-reconnect) overdue evaluation, per-schedule last-success tracking.
 - [x] **NS-04** Dashboard parity with the alerts screen: live refresh, column sorting, filters. ✅ Landed: `/` now parses `q`/`status`/`repo_status`/`tag`/`sort`/`dir` query params (round-trip durable for bookmarks); table is wrapped in an `id="hosts-table"` htmx live-poll matching the alerts cadence (5s, gated on `document.visibilityState` and `localStorage.rm-dashboard-live`); filter row above the table with hostname free-text + status + repo_status selects + tag chips + clear; column headers (Host / OS · arch / Last backup / Repo size / Snapshots) are clickable links that toggle direction on the active column; pure-Go sort+filter pipeline covered by `dashboard_filter_test.go`. Original scope below. live refresh, column sorting, filters. The host list is currently a static render — operators have to reload to see new heartbeats / job state changes. Mirror the alerts pattern (`web/templates/pages/alerts.html` uses `hx-trigger="every 5s [document.visibilityState==='visible' && localStorage.getItem('rm-alerts-live')!=='off']"` plus a Live/Off toggle so background tabs and explicit-off don't burn server cycles). Add: server-side sort on every meaningful column (name, OS, last-backup time, last-backup status, agent online/offline, restic version, tags), and a small filter row above the table — at minimum free-text on hostname, status (online/offline/never-seen), and tag chips. Columns + filter state should round-trip through query string so a bookmarked / shared URL is durable. Re-use the `host_row` partial that already exists so the live-refresh swap is a clean OOB swap, not a full table re-render.
