feat(updater): tier 1 — notify admin and pad users of available updates (#7601)
* docs(updater): add four-tier auto-update design spec

Four-tier opt-in self-update subsystem (off / notify / manual / auto / autonomous).
GitHub Releases as source of truth; install-method auto-detection with admin
override; in-process execution with supervisor restart; 60s drain + announce;
auto-rollback on health-check failure with crash-loop guard. Pad-side severe/
vulnerable badge that does not leak the running version. Top-level adminEmail
with escalating cadence (weekly while vulnerable, monthly while severe).

Refs: docs/superpowers/specs/2026-04-25-auto-update-design.md

* docs(updater): add PR 1 (Tier 1 notify) implementation plan

Bite-sized TDD task breakdown for shipping Tier 1 notify only:
- VersionChecker, InstallMethodDetector, UpdatePolicy, Notifier, state modules
- /admin/update/status (admin-auth) and /api/version-status (public, no version leak)
- Admin UI banner + read-only update page + nav link
- Pad-side severe/vulnerable footer badge
- Settings: updates.* block + top-level adminEmail
- Tests: vitest unit + mocha integration + Playwright admin/pad
- CHANGELOG + doc/admin/updates.md

PRs 2-4 (manual/auto/autonomous) get their own plans after PR 1 lands.

* feat(updater): add shared types for auto-update subsystem

* feat(updater): clarify OutdatedLevel and EMPTY_STATE doc, drop path header

* feat(updater): add semver helpers and vulnerable-below parser

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(updater): tighten semver regex to reject four-part versions

* feat(updater): add state persistence with schema validation

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(updater): reject null email and array latest in state validation

typeof null === 'object' meant {email:null} passed the old isValid check,
which would crash downstream Notifier code reading email.severeAt. Likewise,
an array would pass the typeof latest === 'object' branch. Introduce
isPlainObject helper (null-safe, Array.isArray guard) and use it for both
fields. Adds two regression tests covering the exact broken inputs.

* feat(updater): add install-method detector with override

* feat(updater): add policy evaluator

* feat(updater): add GitHub Releases checker with ETag support

* fix(updater): validate release fields and preserve ETag on prerelease

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* feat(updater): add email cadence decider

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(updater): tagChanged email fires regardless of cadence; drop unused field

* feat(settings): add updates.* and adminEmail settings

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* feat(updater): wire boot hook and periodic checker

Register expressCreateServer/shutdown hooks in ep.json and implement
the boot-wiring module that detects install method, starts the polling
interval and runs the notifier dedupe pass each tick.

* feat(updater): add /admin/update/status and /api/version-status endpoints

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* i18n(updater): add english strings for update banner, page, and pad badge

* feat(updater): add pad footer badge for severe/vulnerable status

* feat(admin-ui): add update banner, page, and nav link

Add UpdateStatusPayload to the zustand store, a persistent UpdateBanner
rendered in the App layout, a /update page showing version details and
changelog, and a Bell nav link — all wired to the /admin/update/status
endpoint added in Task 10.

* test(updater): add Playwright specs for admin banner/page and pad badge

* docs(updater): document tier 1 settings, badge, email cadence

* refactor(updater): dedupe helpers, fix misleading log, add banner styling

- Export stateFilePath from index.ts and import it in updateStatus.ts (removes local duplicate)
- Import getEpVersion from Settings.ts in both index.ts and updateStatus.ts (removes two local definitions)
- Fix misleading 'backing off' log message — no backoff is implemented, just retries at next interval
- Remove EMPTY_STATE_FOR_TESTS re-export from state.ts; state.test.ts now imports EMPTY_STATE directly from types.ts
- Add .update-banner and .update-page CSS rules to admin/src/index.css

* fix(updater): address review feedback — async wrap, tier=off skip, poll race, opt-in admin gate

- Wrap /api/version-status and /admin/update/status with a small async helper
  so a rejected promise becomes next(err) instead of an unhandled rejection.
- Short-circuit route registration when updates.tier === 'off' so the heavier
  opt-out also removes the HTTP surface (matches pre-PR behavior for that case).
- Add an in-flight guard around performCheck() so overlapping interval ticks
  can't race on update-state.json writes or duplicate email decisions; track
  the initial setTimeout handle and clear it in shutdown().
- Add updates.requireAdminForStatus (default false) so admins can lock
  /admin/update/status to authenticated admin sessions without disabling the
  updater. Default false preserves current behavior (the running version is
  already exposed publicly via /health). Backend specs cover unauth → 401,
  non-admin → 403, admin → 200.
- Bump admin troubleshooting menu count test 5 → 6 to account for the new
  Update nav link.

* fix(updater): address Qodo round-2 review feedback

Round 2 of Qodo review on #7601. Addressing the action-required items:

#1 Badge bypassed pad baseURL — derive basePath the same way
   padBootstrap.js does (`new URL('..', window.location.href).pathname`)
   and prefix the fetch with it. Subpath deployments now reach
   /<prefix>/api/version-status instead of 404ing.

#2 Updater poller could get stuck — `getCurrentState()` is now inside
   the try/finally so a one-time loadState() rejection can't leave
   `checkInFlight=true` and permanently silence polling.

#3 Updates off hung admin page — UpdatePage now self-fetches and
   renders explicit `disabled` (404), `unauthorized` (401/403), and
   `error` states instead of staying on "Loading...". Banner-driven
   prefetch is still honoured if it landed first.

#11 NaN polling interval — coerce `checkIntervalHours` to a number,
   clamp to [1h, 168h], log a warning and fall back to 6h on
   non-finite input. Math.max(1, NaN) === NaN previously meant a
   malformed settings.json could turn the poller into a tight loop.

#13 State validation accepted broken subfields — `isValid()` now
   inspects `latest.{version,tag,body,publishedAt,htmlUrl,prerelease}`,
   `vulnerableBelow[].{announcedBy,threshold}`, and
   `email.{severeAt,vulnerableAt,vulnerableNewReleaseTag}`. A
   hand-edited file with a number where a string is expected is now
   treated as corrupt and reset to EMPTY_STATE rather than crashing
   later in semver parsing or email rendering.

#14 Badge cache stampede — wrap `computeOutdated()` in a single-flight
   promise so concurrent requests at cache expiry await one shared
   computation instead of fanning out into N redundant disk reads.

Plus six new state.test.ts cases covering each new validation guard.

Pushing back on the remaining items:

#4 `updates.tier` defaults to `notify` — intentional. The whole point
   of tier 1 is to surface the "you are behind" signal to admins by
   default. Opt-in defeats the purpose; the existing failure mode
   (admin never hears about a security-relevant release) is exactly
   what this PR is fixing.

#5/#8 Admin status endpoint admin-auth — `currentVersion` is already
   public via `/health`, so wrapping the route in admin-auth doesn't
   reduce the disclosure surface meaningfully. Operators who want it
   gated set `updates.requireAdminForStatus=true` (already wired and
   covered by the comment on the route handler).

#10 Plain `https://` URLs in planning doc — planning markdown is
   viewed in editors and on GitHub where protocol-relative URLs would
   either render literally or break entirely. Keeping `https://`.
