steve 14b703be58 server: maintenance ticker drives forget/prune/check on cadence
Wires a 60s server-side ticker to the pure-logic maintenance.Decide
introduced in the previous commit. Decisions flow through a new
DispatchMaintenance method on *Server, which:

  - skips offline hosts (no pending_runs queueing — maintenance is
    not a backup, missed fires shouldn't pile up)
  - silently skips prune when admin creds aren't bound
  - pushes admin creds before prune, then dispatches with
    RequiresAdminCreds=true (same as operator-driven prune)
  - persists job rows with actor_kind="system"

Reshapes the forget wire payload from a single RetentionPolicy to a
ForgetGroups list (one tag + per-group keep-* per source group). The
agent walks the groups and runs `restic forget --tag <name> --keep-*`
once per group. Dead-code removed: CommandRunPayload.RetentionPolicy,
the old forget JSON-decode in cmd/agent, and the single-policy form of
restic.RunForget.

steve e93eb2a060 restic: tighten RunCheck lock sniff + RunStats zero-snapshot test
Narrow the LockPresent predicate from bare "locked" (too broad) to
"stale lock" and "already locked" — the two phrases restic actually
emits. Replace TestRunCheckParsesLock with table-driven
TestRunCheckLockSniff covering both trigger phrases and a benign
"locked-file" line that must not set LockPresent. Add
TestRunStatsZeroSnapshots to pin that RunStats accepts zero-snapshot
JSON without error.

steve 485f4322cb restic: RunUnlock + RunStats (raw-data mode)
Add RunUnlock (delegates straight to runWithPump) and RunStats which
runs `restic stats --json --mode raw-data`, captures the single JSON
line from stdout into RepoStats, and returns an error if no JSON
arrives.  Tests cover arg plumbing for unlock, JSON parsing, and the
no-JSON error path.

steve b24faf6de7 restic: RunCheck with subset% + lock-state sniffing
Add CheckResult (LockPresent, ErrorsFound) and RunCheck.  subsetPct>0
passes --read-data-subset N% to limit data reads.  Stderr is sniffed
for "Found stale lock"/"locked" to set LockPresent; a non-zero exit
from restic is absorbed as ErrorsFound=true rather than an error so
the caller can always persist last_check_status.  Tests cover lock
detection, exit-1 absorption, and subset-arg plumbing.

steve 9b790bbade restic: RunPrune + runWithPump helper, refactor Forget/Init onto it
Add RunPrune for admin-credential prune invocations.  Extract
runWithPump to DRY the stdout+stderr pump pattern; refactor RunForget
and RunInit to delegate to it (RunInit preserves the "config file
already exists" soft-success sniff by wrapping the handler before the
call).  Add runner_test.go with TestRunPruneInvokesPrune.

steve b6f8de1dcc lint: drive baseline to zero, drop only-new-issues gate
Cleanup pass over the repo so CI can enforce lint going forward
without the only-new-issues escape hatch:

* gofumpt -w across the tree (31 hits, all formatting)
* misspell --fix (25 hits, US-locale spelling) — but reverted on
  api.JobCancelled = "cancelled" since that literal is the wire +
  DB CHECK constraint value, plus matched the case in store/fleet.go
  back to "cancelled" and added //nolint:misspell on both for the
  next time someone reaches for the auto-fix
* Wrap every `defer rows.Close()` / `defer stmt.Close()` /
  `defer res.Body.Close()` in `defer func() { _ = .Close() }()`
  to satisfy errcheck without losing the close itself
* websocket.Dial callers (1 prod, 4 tests) now capture + close the
  upgrade response Body — coder/websocket can return res with a nil
  Body on success, so the test deferred-closes guard against that
* Annotate the two genuine-by-design nilerr cases with //nolint
  comments explaining why nil-on-error is the contract (cookie
  missing = no session; ctx cancelled mid-backoff = clean shutdown)
* Add brief godoc on the 10 exported const groups + types that
  revive flagged (api.HostOS/HostArch/JobKind/JobStatus/LogStream/
  ErrorCode, restic.EventKind, store.Role, web.FS)
* Drop the unused (*Server).userByID method
* Inline the unparam baseView(active) — every UI page is under
  the dashboard primary nav today

Result: `golangci-lint run ./...` reports 0 issues. CI lint job
no longer needs only-new-issues: true; X-06 follow-up entry in
tasks.md removed.

steve 6a171596f1 P2-05: forget command with retention policy
End-to-end forget plumbing — operator can create a forget schedule
with keep-* values, agent runs restic forget --keep-* … on the
schedule's cron (or via per-row Run-now), snapshot list shrinks,
UI updates.

* api.CommandRunPayload gains retention_policy json.RawMessage so
  the agent doesn't need a typed copy of the server-side struct.
* restic.ForgetPolicy mirrors restic's --keep-* flags. Empty()
  reports zero dimensions; restic wrapper RunForget refuses to
  run an empty policy (would delete every snapshot). Does NOT
  pass --prune — pruning lives behind a separate admin-only
  credential (P2-06); forget just rewrites the snapshot index.
* runner.RunForget mirrors RunBackup's envelope shape so the
  live log viewer works without special-casing. On success
  triggers reportSnapshots (forget shrinks the index, the host's
  snapshot count almost certainly changed).
* cmd/agent dispatcher handles MsgCommandRun with kind=forget,
  decodes RetentionPolicy from the wire, builds restic.ForgetPolicy.
* Server dispatchScheduleNow marshals the schedule's
  RetentionPolicy into the wire payload for kind=forget jobs.
  Refuses to dispatch a forget schedule with empty retention.
* validateSchedule rejects kind=forget without at least one keep-*
  dimension (new error code: missing_retention).
* UI schedule edit form gains a Kind dropdown (backup or forget;
  immutable on edit). Paths block toggles by kind via inline
  data-kind attributes. Form help-text explains the prune
  separation.

Other kinds (prune, check, unlock) deferred to P2-06..08; the
Kind dropdown only offers backup and forget today.

steve 413d0bdb1b restic: don't fall back to parent's HOME when picking the cache dir
Agent runs as root (HOME=/root from systemd) with ProtectHome=
read-only, so restic's `mkdir /root/.cache/restic` fails on the
first call. Backups still completed (restic falls back to no-cache)
but every job log started with a noisy red "unable to open cache"
warning.

Default to /var/lib/restic-manager unconditionally — that's already
in the unit's ReadWritePaths and survives ProtectHome. ExtraEnv
overrides still win for tests / unusual setups.

steve f692ad592c restic: treat 'config file already exists' on init as soft success
Re-running restic init on a repo that's already initialised exits
non-zero with "Fatal: ... config file already exists". Semantically
that's a no-op, not a failure — the repo IS initialised, the
caller's intent is satisfied. Sniff stderr for the magic string
and swallow the exit code in that case, emitting an event line
so the operator-facing log says what happened.

Caught while smoke-testing P2-04.5: I'd init'd the repo manually
during a debug session, then the operator clicking the UI's
Init-repo button would hit this and the host's repo_initialised_at
would never flip.

steve c8ead66f08 P1 polish: agent-as-root, init-repo flow, rest creds passthrough, UX fixes
Cohesive batch from a smoke-test session against a real rest-server.
Themed bullets:

* Agent runs as root, sandboxed via systemd. CapabilityBoundingSet
  drops to CAP_DAC_READ_SEARCH + restore caps; ProtectSystem=strict
  with ReadWritePaths confined to /etc + /var/lib/restic-manager;
  NoNewPrivileges blocks escalation. Install script no longer
  creates a service user. spec.md §4.2 / §14.1 / §14.3 explain the
  rationale (matches UrBackup / Veeam / Bareos defaults; trying to
  back up "everything" as an unprivileged user creates silent skips
  on /home, /root, /var/lib/* with no upside vs the threat model
  the agent already implies).

* Init-repo end-to-end. New JobKind="init" wired through agent
  runner, restic.Env.RunInit, server dispatcher, and a UI button
  (red "Initialise repo" in the run-now panel). hosts.repo_initialised_at
  flips on init success, on backup success, or on a non-empty
  snapshots.report. The "Run now" / "Init" / "Retry" branching now
  drives both the dashboard host row and the host-detail panel.
  Migrations 0004 (column), 0005 (jobs.kind CHECK widened — using
  the safe create-new-then-rename pattern; first version corrupted
  job_logs.job_id FK), 0006 (cleans up job_logs FK on already-
  affected DBs).

* rest-server creds embedded at exec time only. restic.Env gains
  RepoUsername; mergeRestCreds() builds the user:pass@-prefixed URL
  inside envSlice() and never assigns it back to the struct, so
  nothing slog-able ever sees the cleartext form. RedactURL helper
  for any future surface that needs to log a URL safely. Both
  helpers tested.

* Add-host UX. Repo password is now optional — server mints a
  24-byte URL-safe random one and surfaces it once, alongside an
  htpasswd snippet ("echo PASS | htpasswd -B -i ... USERNAME") so
  the operator pastes one command on the rest-server host and one
  on the endpoint. Result page also links the install snippet at
  /install/install.sh (was /install.sh — 404'd before) and pipes
  to bash (not sh — script uses set -o pipefail and other
  bashisms; on Debian/Ubuntu sh is dash).

* Late-subscriber race in JobHub. A fast-failing job could finish
  (DB write + Broadcast) before the browser's HX-Redirect → page
  load → WS-connect path completed, so the JS sat forever waiting
  on a job.finished that already passed. JobHub split into
  Register + Send + Run; handleJobStream now subscribes first,
  re-fetches the job, and sends a synthetic job.finished if the
  state is already terminal.

* HTMX error visibility. New toast partial listens to
  htmx:responseError and surfaces the response body as a
  bottom-right toast — every server-side validation error now
  becomes visible without per-handler JS wiring. Also handles
  custom rm:toast events for future server-pushed notifications
  via the HX-Trigger header. Themed via existing CSS vars.

* Dashboard rows are now whole-row clickable to host detail
  (CSS card-link pattern: absolute-positioned anchor + .row-action
  z-index restoration so the action button stays clickable).
  "View →" on a running job links to /jobs/<id> rather than
  /hosts/<id> since the row click already covers the host page.

* "Run first" / "Run first backup" → "Run now" everywhere for
  consistency.

* runbook (docs/e2e-smoke.md) updated — live-log streaming step
  now reflects P1-26; mentions the browser-driven Run-now flow.

* _diag/dump-creds — moved out of cmd/ so go build doesn't pick
  it up; .gitignore now excludes /_diag/ entirely.

steve 8aa635f0c1 P1 polish: Host.default_paths interim + restic env hygiene + job_id JS quoting
Two fixes that close the loop on dashboard run-now and harden the
agent's restic invocation.

Default paths (interim until P2-01 schedules):
  - 0003 migration adds default_paths TEXT NOT NULL DEFAULT '[]'
    to hosts and to enrollment_tokens.
  - Operator types paths in the Add-host form (textarea, one per
    line). They ride on the enrol_token row alongside the
    encrypted creds (paths aren't secret — plain JSON column).
  - On consume, ConsumeEnrollmentToken still just burns the token;
    the new GetEnrollmentTokenAttachments returns both the
    re-bindable creds and the path list in one round trip, the
    handler transfers them onto the new host row inside CreateHost.
  - The dashboard's Run-now and host-detail's "Run backup now"
    button now read Host.DefaultPaths and pass them to dispatchJob.
    A host with no default paths returns 400 with a friendly
    "no paths set" message instead of dispatching a doomed
    `restic backup` with no positional args.
  - Doc comments explicitly call this out as a Phase 1 interim —
    schedules supersede.

Restic env hygiene:
  - envSlice() previously omitted HOME / XDG_CACHE_HOME, which
    bit the smoke runs whenever the agent was launched outside
    systemd (restic refused to start: "neither $XDG_CACHE_HOME
    nor $HOME are defined"). Now both are set explicitly: prefer
    Env.ExtraEnv overrides, fall back to the agent process's own
    HOME, and finally to /var/lib/restic-manager.
  - Comment makes the env policy explicit: parent's RESTIC_* /
    AWS_* / B2_* env is filtered out by design — control-plane
    is the unambiguous source of truth.

JS bug fix in the live log page:
  - {{$job.ID | printf "%q"}} produced a literal-quoted JS string,
    which then went into the WS URL as ".../jobs/"<ID>"/stream"
    → 404. Switched to '{{$job.ID}}' inside the literal so
    html/template's auto-escape does the right thing. Verified
    end-to-end: dashboard "Run now" → live progress + log lines
    arrive over the WS → succeeded pill renders.

steve a7c6a6e09c phase 1: run-now backup — restic wrapper, job lifecycle, end-to-end
Lands the operator → server → agent → restic → server roundtrip for
on-demand backups. The flow:

  POST /api/hosts/{id}/jobs {kind:"backup",args:["/path"]}
    → server creates a queued Job row
    → server emits command.run over WS to the host's agent
    → agent dispatcher spawns runner.RunBackup in a goroutine
    → runner spawns `restic backup --json`, parses each line
    → forwards: job.started, log.stream (every line), job.progress
      (throttled to 1/sec), job.finished (with summary stats blob)
    → server WS handler persists those into jobs / job_logs

P1-16 internal/restic: thin Locate + Env wrapper that runs `restic
  backup --json`, scans stdout/stderr, parses BackupStatus +
  BackupSummary, calls back into a LineHandler so the agent can fan
  out to log.stream + job.progress. Treats exit code 3 as
  "succeeded with issues" (matches restic's contract).

P1-18 store: jobs accessors (CreateJob, MarkJobStarted,
  MarkJobFinished, AppendJobLog, GetJob).

P1-19 server: POST /api/hosts/{id}/jobs creates the Job row,
  validates kind, dispatches via Hub.Send, audit-logs the action.

P1-20 agent runner: wraps restic.RunBackup with throttled progress
  emission. Sender abstraction was added to wsclient.Handler so
  background goroutines can keep replying after dispatch returns.

P1-21 server WS: dispatchAgentMessage now persists job.started,
  job.finished, log.stream into the database. Browser fan-out for
  live tailing lands with the UI work.

Agent gets repo_url + repo_password from agent.yaml in plaintext
for now (mode 0600, owned by service user); spec.md §7.3's keyring
storage moves there in P2. config.update over WS overrides the
in-memory copy (does not persist).

Build clean; all tests pass. End-to-end with a real restic still
needs a host that has restic installed — wire shape verified by
the existing hello/heartbeat round-trip test.
