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.

P1-33: agent-side encrypted secrets store + push-on-update
New internal/agent/secrets package: AEAD blob at /var/lib/restic-manager/secrets.enc, atomic write (os.CreateTemp + Sync + Rename), 0600. Key lives in agent.yaml as base64 (SecretsKey) — same trust boundary as the bearer token, minted on first start via EnsureSecretsKey. cmd/agent: dispatcher reads creds fresh from secrets.Load() on each job rather than from in-memory config. config.update merges the push with what's on disk and persists, so a daemon restart keeps the latest values. Legacy plaintext repo_url/repo_password in agent.yaml are silently migrated into secrets.enc on next start and stripped from the YAML on the following save. Tests: round-trip + wrong-key rejection + atomic-write post-condition for secrets; key idempotence + legacy-field parse/clear for config.

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.

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.

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.
