steve a086b0eb75 P2-02 (server side): schedule reconciliation push + ack handling
Server is now the source of truth for the agent's cron set.

* Helpers in schedule_push.go:
  - loadScheduleSetPayload reads the host's schedules + canonical
    version into the wire shape.
  - pushScheduleSetOnConn writes directly to a just-handshaken conn
    (avoids racing against Hub.Register on a brand-new connection).
  - pushScheduleSetAsync is the post-CRUD flavour — no-op when the
    host is offline (the next reconnect's on-hello path catches it
    up, so a missed push is non-fatal).
  - applyScheduleAck records what version the agent has confirmed.

* onAgentHello restructured: was returning early when the host had
  no repo credentials, which made the schedule push unreachable for
  fresh hosts. Split into pushRepoCredsOnHello (silent no-op on
  ErrNotFound) + pushScheduleSetOnConn (always runs). Empty schedule
  list is a valid push: tells the agent to drop stale cron entries.

* WS dispatcher gains an OnScheduleAck hook on HandlerDeps; the
  http server wires it to applyScheduleAck. MsgScheduleAck moves
  out of the "TODO(P2)" group into a real case that decodes the
  payload and forwards to the callback.

* Schedule CRUD handlers each fire pushScheduleSetAsync after the
  audit-log write so the agent picks up changes within seconds.

Tests cover:
  - On-hello push of an already-created schedule, agent acks,
    applied_schedule_version flips on the host row.
  - Connect-then-CRUD: empty initial push (version 0), then a
    follow-on push at version 1 after the operator creates a
    schedule via REST.

Agent-side `schedule.set` handler (parse, replace local cron,
emit `schedule.ack`) is the remainder of P2-02 and lands with
P2-03's local scheduler.

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 e6729a5a3d P1-26: live job log viewer + WS browser fan-out hub
Closes the P1-21 remainder.

internal/server/ws/jobhub.go — new JobHub. Per-job_id set of
subscribers; each gets a 64-deep buffered channel with a writer
goroutine. Broadcast is non-blocking: if a subscriber is slow,
its channel fills and messages are dropped for that subscriber
only — the agent's read loop is never blocked by a stuck browser.

The agent dispatchAgentMessage path mirrors job.started /
job.progress / log.stream / job.finished envelopes onto the hub
in addition to its existing persistence work. The wire shape is
the same end-to-end, so client-side JS switches on env.type the
same way Go code does.

GET /api/jobs/{id}/stream is the browser endpoint. Auth via
session cookie (HTTP layer); upgrade; subscribe; pump until
context closes.

GET /jobs/{id} renders the live log page. Three states (queued/
running/succeeded/failed) drive the header pill, the progress
bar block, the failure summary panel, and the action button
(Cancel job while running, Back to host afterwards). Already-
persisted log lines are server-rendered on initial load; new
lines arrive over the WS and append to #log-stream. Auto-scrolls
unless the user scrolls up (a "⇢ Follow" pill re-attaches).
On job.finished the page reloads after 600ms to pick up the
final-state header rendered server-side.

POST /hosts/{id}/run-backup now sets HX-Redirect → /jobs/{job_id}
on success so HTMX lands the operator straight on the live log.
For non-HTMX callers (curl / plain form post) it 303s to the
same target.

store.ListJobLogs returns persisted log lines for initial render
on page load.

Browser-verified end-to-end: enrol → run a real backup against a
sibling restic/rest-server → live progress + 11 log lines stream
in → succeeded pill + final stats land after page reload.

steve b3b89045f2 P1-32: server-side encrypted repo creds + push-on-hello
Operator-minted enrollment tokens now carry the repo URL/username/
password as one AEAD blob bound (via additional-data) to the token
hash. ConsumeEnrollmentToken re-encrypts under host_id and writes a
host_credentials row in the same tx as token-burn, so the binding
moves with the credential.

PUT /api/hosts/{id}/repo-credentials lets an operator edit creds
post-enrollment; merges with the existing blob, audits, and pushes
config.update if the agent is connected.

WS handler grows an OnHello hook that the HTTP layer wires to send
the host's decrypted creds as a config.update immediately after the
hello succeeds — synchronously, so a racing command.run lands after
the agent has its repo password.

Schema: 0002_host_credentials.sql adds enc_repo_creds to
enrollment_tokens and a host_credentials table (PK = host_id, FK
ON DELETE CASCADE).

Tests: round-trip token → consume → host_credentials with AAD swap
detection; no-creds path stays compatible.

steve 8d5282a180 P1-22: snapshot listing via restic snapshots --json
Agent calls restic snapshots --json after each successful backup
(60s timeout, separate from the backup ctx) and ships the projection
over the existing snapshots.report WS envelope. Failure here is
logged but doesn't fail the job — the next successful backup catches
the projection up.

Server-side ReplaceHostSnapshots is delete-then-insert plus a
hosts.snapshot_count update in one transaction so the dashboard's
per-host count stays consistent with the projection. New read
endpoint GET /api/hosts/{id}/snapshots returns the cached list with
a refreshed_at marker so the UI can show staleness when an agent
has been offline.

Schema: dropped the unused snapshots.repo_id FK (repos as a
first-class entity is P2 work), added short_id and refreshed_at
columns, switched the time index to DESC for the most-recent-first
list query. api.Snapshot gains short_id; size_bytes/file_count come
from the embedded summary block on restic 0.16+ and stay zero on
older clients.

Tests cover round-trip, authoritative replacement after forget+prune
shrinkage, and empty-after-wipe.

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.

steve 9cc0caff1e phase 1: WS transport, enrollment, agent that hellos and heartbeats
Lands the protocol layer end-to-end: an agent can be enrolled
through the operator UI, store credentials, dial back to the server
over WS, complete the protocol_version handshake, and stay
connected with periodic heartbeats.

Server side:
- P1-09 ws.Hub: one Conn per host_id, last-write-wins eviction,
  json envelope writer with a write mutex, reader, error envelopes.
- P1-09 ws.AgentHandler: bearer-auth, accept upgrade, hello-stage
  (10s deadline, protocol_version checked against
  api.MinAgentProtocolVersion → ErrProtocolTooOld with help URL on
  reject), main read loop, defer hub register/unregister.
- P1-10 POST /api/agents/enroll consumes a one-time token, mints a
  persistent agent bearer (sha-256 stored), creates a host row.
- P1-10 POST /api/enrollment-tokens (operator, session-auth)
  issues a 1h one-time token.
- P1-11 hello upserts agent_version + restic_version +
  protocol_version on the host row, flips status to online.
- P1-12 heartbeat touches last_seen_at; background sweeper marks
  hosts offline after 90s without one.
- store: hosts table accessors, host_schedule_version,
  enrollment_tokens FK on consumed_host dropped (audit-only field;
  the token gets burned before the host row exists).

Agent side:
- P1-13 internal/agent/config: yaml at /etc/restic-manager/agent.yaml,
  atomic Save (tmp+fsync+rename), Enrolled() helper.
- P1-15 internal/agent/wsclient: dial with bearer + optional
  TLS cert pinning (sha-256 of leaf), exponential backoff with
  jitter (1s → 60s cap), heartbeat goroutine, fatal handling for
  ErrProtocolTooOld.
- P1-15 wsclient.Enroll: HTTP POST /api/agents/enroll with sysinfo.
- P1-17 internal/agent/sysinfo: hostname/OS/arch/restic-version
  collection. restic detected by `restic version` parse; absent
  restic doesn't block startup.
- cmd/agent: -enroll-server / -enroll-token flags drive first-run
  enrollment then exit (so the install script can hand off to
  systemd to run the persistent service).

End-to-end smoke verified: bootstrap → login → issue token →
enroll → run agent → server logs `ws agent connected` with the
right host_id and protocol_version 1.

All tests still pass.
