End-to-end wizard from /hosts/{id}/restore (or per-snapshot deep link
/hosts/{id}/snapshots/{sid}/restore) → tree-browse → dispatch →
restore-shaped live job page.
Backend (internal/server/http/ui_restore.go):
- GET handlers render the four-step wizard against the wireframe shape
in docs/superpowers/specs/2026-05-04-p3-restore-design.md.
- HTMX tree partial endpoint hits fetchTreeWithCache (P3-X2) so each
directory expansion is a sub-second cached lookup after the first
miss.
- POST validates: snapshot_id non-empty, ≥1 absolute path, in-place
mode requires confirm_hostname == host name, agent online. On error
re-renders the wizard with the operator's input intact. Happy path
mints a job_id, computes the new-directory target as
/var/restic-restore/<job-id>/ (operator can't escape the prefix —
server picks it), creates the job row, ships command.run with
kind=restore + RestorePayload, writes a host.restore audit row,
returns HX-Redirect (or 303) to the live job page.
Templates:
- host_restore.html: single-page progressively-enabled wizard matching
_diag/p3-restore-wizard wireframe. Form-state-driven JS computes a
running tally of selected paths and the step-4 confirm summary
client-side; the server re-renders on validation failure with form
fields preserved.
- partials/tree_node.html: recursive HTMX-served tree fragment.
- Top-level Restore button on host_detail right rail + per-snapshot
Restore action on snapshot rows replace the previous P3-stub.
Restore-shaped job page (job_detail.html):
- Progress widget rendered as a panel rather than a bare strip when
the job is active.
- Current-file display under the bar, updated from log.stream stdout
lines that look like absolute paths. Hidden for non-restore kinds.
Migration 0012:
- Add restore + diff to the jobs.kind CHECK. Rebuild required (SQLite
can't ALTER CHECK in place); follows the safe pattern from 0005.
Defensive: stash job_logs into a temp table before the rebuild and
INSERT OR IGNORE back afterwards so even if SQLite cascades on
DROP TABLE jobs the log history survives.
Tests:
- ui_restore_test covers GET step-1 render, GET pre-selected snapshot
summary card, POST missing snapshot, POST missing paths, POST
in-place wrong-hostname rejection (no command.run leaks to the
agent), POST happy path (HX-Redirect + correct payload + audit
row), POST against offline host returns 503.
Restage block (CLAUDE.md) deferred to the end of the restore phase.
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.

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.
