   - **Auto-init at enrolment**: server dispatches `restic init` on first WS connect (was P2-old "Init repo" button — now invisible to the operator). On success: emit a normal job row with `kind=init` so the audit trail still shows it. On `init` returning "config file already exists" (e.g. re-enrolment against an existing repo): treat as soft success per existing restic-wrapper behaviour.
   - **Tests**: rewrite the deleted `schedules_test.go` and `schedule_push_test.go` against new endpoints; new `source_groups_test.go`, `repo_maintenance_test.go`, `auto_init_test.go`. End-to-end: enrol → server pushes creds → server dispatches init → agent runs it → schedule reconcile fires → operator hits per-source-group Run-now → backup runs → snapshots refresh.

+### P2 redesign — Phase 4 (UI rewire, against v4 wireframes) ✅
 
-- [ ] **P2R-02** (L) UI templates rebuilt against the new model:
-  - `/hosts/{id}/sources` — list of source groups with per-row meta (includes/excludes count, retention summary via `RetentionPolicy.Summary()`, usage = which schedules reference this group, snapshot count for `tag = group.name`). Run-now / Edit / Delete actions per row.
-  - `/hosts/{id}/sources/{gid}/edit` (and `/sources/new`) — name (= snapshot tag), includes/excludes textareas, retention as a 3×2 keep-* grid, retry-on-offline, inline conflict banner above retention when granularity ↔ cadence mismatch detected (uses `SourceGroup.conflict_dimension` cache).
-  - `/hosts/{id}/schedules` — slim list (status / cron / source-tags / actions) plus new-schedule form (cron with quick-pick chips, source-group multi-select via clickable check pickers, enabled toggle).
-  - `/hosts/{id}/repo` — connection (URL/user/password — pre-filled from `GET /api/hosts/{id}/repo-credentials` redacted view; cert pin), bandwidth caps (host-wide), maintenance rows (forget/prune/check cadence + check subset %), danger-zone re-init.
-  - **Re-enable the four host-detail sub-tabs** (Snapshots is already live; Schedules / Sources / Repo become real links again; Settings stays inert until later). Drop the stop-gap inert-div hack from P2R-00.4.
-  - **Per-source-group Run-now buttons** replace today's per-host `Run backup now` buttons (right-rail + dashboard row + empty-snapshots state). Dashboard row's Run-now becomes either "Run all groups" (if exactly one schedule covers all groups) or "Open →" (multi-group hosts).
-  - Header "version N · agent in sync / agent at vM" indicator preserved (still backed by `host_schedule_version` + `applied_schedule_version`).
+> **Row-design rule (binding for every list-row template in this app, current and future):**
+> Whole-row click navigates to the row's primary detail/edit page —
+> mirror `.host-row.clickable` on the dashboard
+> (`partials/host_row.html`): an absolute-positioned `.row-link`
+> overlay with `text-indent: -9999px` covers the row, action buttons
+> live in `.row-action` cells that sit above via z-index. **Do not
+> add an explicit "Edit" button** when the row is clickable — it
+> duplicates the affordance and dilutes the click target. Action
+> cells are reserved for verbs that aren't "open this row" (Run-now,
+> Delete, Pause, etc).
+
+- [x] **P2R-02** (L) UI templates rebuilt against the new model:
+  - **Slice 1 ✅** Sub-tab navigation skeleton — extract header/vitals/sub-tabs into a `host_chrome` partial; Sources / Schedules / Repo become real `<a>` links; placeholder pages share the chrome; version indicator restored. (commit `a535822`)
+  - **Slice 2 ✅** Sources tab — `/hosts/{id}/sources` list with per-row meta + clickable rows + per-group Run-now/Delete; `/sources/new` and `/sources/{gid}/edit` form (name, includes/excludes, 3×2 keep-* grid, retry-on-offline, inline conflict banner from `ConflictDimension` cache); validation re-renders form with input intact; refuses to delete a host's last source group. (commits `0ed9c3d`, `dede74f`)
+  - **Slice 3 ✅** Schedules tab — `/hosts/{id}/schedules` slim list (status / cron / source-tags / actions, clickable rows) plus `/schedules/new` and `/schedules/{sid}/edit` form (cron with five quick-pick chips that have human-readable tooltips, source-group multi-pick as styled check cards, enabled toggle); per-schedule Run-now reuses `dispatchScheduledJob` for enabled schedules + bypasses the enabled check (with a HX-confirm) for paused ones; multi-group fires emit a success toast, single-group fires HX-Redirect to the live job log. (commit `67ca769` + follow-ups `64d2fcf`, `8b91d30`, `4035c44`)
+  - **Slice 4 ✅** `/hosts/{id}/repo` — three independent forms (connection: URL/user/password pre-filled from `GET /api/hosts/{id}/repo-credentials` redacted view; bandwidth: host-wide caps via new `PUT /api/hosts/{id}/bandwidth`; maintenance: forget/prune/check cadences + check subset %); danger-zone re-init button rendered + disabled (real flow lands in P2R-09); right-rail snapshots-by-tag breakdown. (commit `d62b173`)
+  - **Slice 5 ✅** Dashboard row Run-now uses the single covering schedule when one exists ("Run all groups" primary button), otherwise falls back to "Open →" pointing at the Sources tab. Right-rail and empty-snapshots-state Run-now were rehomed to source-group context in slice 1. (commit `fab99b4`)
+  - **Slice 6 ✅** Playwright sweep against the live `:8080` server — login → walk every new tab → create source group → create schedule → Run-now → confirm a snapshot landed → end-to-end clean, no console errors. Screenshots in `_diag/p2r-02-sweep/`.
+  - Side-fix: agent runner drops noisy restic `status` events from `log.stream` (they were drowning the live log on short backups; the throttled `job.progress` envelope already covers the same data). (commit `ffba737`)
+  - Header "version N · agent in sync / agent at vM" indicator preserved across all tabs (backed by `host_schedule_version` + `applied_schedule_version`).
   - Form validation re-renders with the operator's typed input intact (mirror P2-04's behaviour). Each save fires `pushScheduleSetAsync` so an online agent re-arms within seconds.
