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 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.

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.
