What changed

  • tolerate nullable Redis-backed quota and PV statistics in the admin user drawer
  • show a retryable error state when the admin identity query fails instead of spinning forever
  • stop create/update/delete mutations from synthesizing incomplete or empty app caches; refetch canonical data instead
  • treat custom API endpoint changes as an authentication boundary by clearing the old session, workspace, and query cache before reload
  • canonicalize endpoint URLs and allow plain HTTP only for local development
  • retire the Service Worker runtime cache: stop registering new workers, actively unregister the legacy root /sw.js registration, and delete only pushy-admin-* caches
  • preserve unrelated same-origin Service Worker registrations during retirement
  • keep /sw.js as a no-fetch tombstone that still attempts to unregister itself when cache enumeration fails
  • retain per-build stale-chunk recovery and the web app manifest/icons without claiming offline support
  • rank distribution-chart legends by cumulative request count rather than equal-weight daily percentages
  • format daily distribution tooltips as dates without a meaningless 00:00

Tests added

  • app mutation cache updater behavior
  • custom endpoint URL normalization and invalid legacy endpoint reset
  • legacy Service Worker matching, isolation, registration/cache retirement, and best-effort failure handling
  • per-build chunk recovery guard
  • distribution ranking under unequal daily traffic
  • daily tooltip time formatting

CodeRabbit follow-up

  • fixed reset of invalid endpoint values persisted by earlier releases
  • fixed the AdminApp intersection so checkCount: number | null remains nullable
  • retired the reviewed runtime-cache response path instead of merely moving maintenance off the response promise
  • additionally restricted Service Worker cleanup to Pushy’s root /sw.js and made tombstone unregistration independent of cache cleanup success
  • resolved all three inline review threads

The docstring-coverage notice is advisory rather than a repository CI requirement. Non-trivial new helpers have API documentation; mechanical docstrings were not added to trivial React callbacks solely to satisfy the external percentage.

Deliberately not changed

The HttpOnly cookie login/logout rollout and credential transport are not modified in this PR.

Validation

  • TypeScript: passed
  • Biome: passed
  • Bun tests: 421 passed, 0 failed
  • Production build and bundle-size gate: passed
  • Bundle: initial 1288 KB / async 3403 KB / total 4690 KB

Supersedes the closed draft #60, which contained the initial version of the same branch and changes.

Treat Redis-backed user metrics as nullable, render missing values as dashes, and replace the admin-route infinite spinner with an explicit retry state.
Keep missing list/detail caches undefined, refetch canonical app data after create/update/delete, and cover the cache updater behavior with unit tests.
Canonicalize custom endpoints, clear credentials/workspace/cache before switching servers, bound the service-worker cache, and allow one stale-chunk reload per UI build.
Select default legend categories from cumulative request counts rather than equal-weight daily percentages, and format daily chart tooltips without a meaningless midnight time.
Apply the formatter output reported by CI.

Review Change Stack

📝 Walkthrough

Walkthrough

The pull request retires legacy PWA state, updates admin session and endpoint handling, improves chunk recovery, synchronizes application mutation caches, and updates metrics, chart, and quota data handling.

Changes

Admin runtime and endpoint control

Layer / File(s) Summary
Legacy PWA retirement
public/sw.js, src/index.tsx, src/utils/service-worker-retirement.ts, src/utils/service-worker-retirement.test.ts
The application unregisters legacy service workers and deletes pushy-admin- caches. The tombstone worker performs the same cleanup and then unregisters itself.
Admin session and query states
src/components/admin-route.tsx
AdminRoute queries api.me, redirects missing sessions, uses route constants, and renders a retryable error state.
Versioned chunk recovery
src/utils/chunk-recovery.ts, src/utils/chunk-recovery.test.ts, src/components/error-boundary.tsx
Chunk reload recovery is shared and keyed by PUBLIC_UI_VERSION. Retry now reloads the page.
Endpoint normalization and switching
src/utils/endpoint.ts, src/utils/endpoint.test.ts, src/components/switch-endpoint-modal.tsx
Endpoint URLs are normalized and validated. Endpoint changes clear session, workspace, and query state before reload.

Application mutation cache

Layer / File(s) Summary
Cache helper contracts and behavior
src/services/mutation-cache.ts, src/services/mutation-cache.test.ts
New helpers update or remove existing list and detail entries without creating missing caches or mutating source objects.
Mutation query synchronization
src/services/mutations.ts
Create, delete, and update mutations revalidate affected queries and remove deleted app detail data.

Admin metrics and quota data

Layer / File(s) Summary
Distribution ordering and chart display
src/pages/admin-metrics.logic.ts, src/pages/admin-metrics.logic.test.ts, src/pages/admin-metrics.tsx
Distribution categories are ordered by total request volume, and distribution tooltips use MM/DD.
Configurable time-series tooltips
src/utils/charts.ts, src/utils/charts.test.ts
Time-series charts accept an optional tooltip time format with MM/DD HH:mm as the default.
Nullable quota rendering
src/services/admin-api.ts, src/components/user-detail-drawer.tsx
Nullable quota and application check-count fields now render placeholder values when data is unavailable.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 28571

This PR improves recovery and endpoint isolation, but resetting a legacy invalid endpoint may still report success without clearing the retained endpoint state, and nullable quota data may remain narrowed by existing types. Startup cleanup can also unregister unrelated service workers on a shared origin, while tombstone cleanup may fail to unregister after cache-enumeration errors. These bounded correctness and browser-isolation risks should be fixed or explicitly accepted before merge.

- Around line 75-76: Update the `/static/` fetch handling around cache.put and
trimCache so cache maintenance runs via event.waitUntil without delaying or
rejecting the network response; catch maintenance errors, and add tests covering
rejected cache.put and cache.delete while preserving the successful response
behavior.

In `@src/components/switch-endpoint-modal.tsx`:
- Line 41: Update the no-op condition in the endpoint reset flow around
currentNormalized so it only matches when the normalized endpoint is non-null
and equals nextUrl; allow null normalization to continue through reset so the
persisted custom endpoint and related state are cleared.

In `@src/services/admin-api.ts`:
- Around line 220-221: Update the intersection type near AdminApp so the
effective checkCount remains number | null by omitting the original checkCount
property first, using Omit<AdminApp, 'checkCount'> combined with the nullable
override.

42-52: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Scope service-worker cleanup to pushy-admin. If other applications can share the origin, serviceWorker.getRegistrations() returns registrations for all scopes, and the unfiltered registrations.map(...) can unregister their workers. Filter by registration.scope before calling unregister(), and add scope to ServiceWorkerRegistrationLike.

CodeRabbit review follow-up

Reviewed all three inline findings and the additional risks called out in the walkthrough.

  • Runtime Service Worker cache: the finding is superseded because the cache-serving fetch path has been removed. The tombstone has no fetch handler, always attempts unregistration even when cache enumeration fails, and application cleanup now targets only the same-origin root /sw.js registration.
  • Invalid legacy endpoint reset: fixed with isEndpointSelectionUnchanged; a non-null legacy value that no longer passes normalization is treated as a real reset, so persisted endpoint/session/workspace/query state is cleared. Regression tests cover remote HTTP and malformed legacy values.
  • Nullable checkCount: fixed with Omit<AdminApp, 'checkCount'> before the nullable override.
  • Same-origin worker isolation: unrelated Service Worker registrations are preserved and covered by tests.

All three inline threads are resolved. The docstring coverage item is an external advisory check, not a repository-required status; the non-trivial new helpers are documented without adding boilerplate comments to trivial callbacks.

Latest validation: TypeScript, Biome, 421 tests, production build, and bundle-size gate all pass.
