Root cause (diagnosed from run logs 513/515/516): the EF migration-integrity
job's "MySql apply all migrations to a fresh DB" step flakes when two migration
jobs land on the SAME runner host at once — each `services: mysql:8.4` container
starves the other, so the 787-migration replay either exceeds MySqlConnector's
30s default command timeout ("Command Timeout expired", run 513 on ci-runner) or
has its connection dropped mid-replay ("MySqlEndOfStreamException", run 516 on
bumblebee-runner). It's pure infra contention: `has-pending-model-changes` (the
model check) passes both providers, and the identical tree passes on a quieter
host (run 515). Both runners have both passed and failed — not one bad runner.
Fix (runner-agnostic, repo-owned workflow only — no runner-host change needed):
- Raise `DefaultCommandTimeout` to 300s in the MySql connection string.
- Wrap the apply in a 3× retry that resumes from `__EFMigrationsHistory` (EF
commits each migration in its own transaction, so an interrupted one rolls back
and the retry continues). A real migration failure fails on every attempt, so
the retry can't mask a genuine problem.
Docs: ci-cd.md migration-integrity section documents the contention + retry.

Run 516's MySQL "apply all migrations to a fresh DB" died with
MySqlEndOfStreamException (incomplete response) — the shared MySQL service
container under concurrent-run load, same class as run 513's Command Timeout.
Model-drift (has-pending-model-changes) passed for BOTH providers, so the diff
is model-clean; another branch's run (515) passed the identical job. Contention
has cleared; re-triggering. Tree unchanged from b6f12f7e.

Run 513's "EF migration integrity" job failed with "The Command Timeout
expired" applying all migrations to a fresh MySQL under concurrent-run
contention. The tree is unchanged from b6f12f7e (Build & test green there and
on the pre-clamp cf834d8b; the change touches no EF/model/migration code).

Re-review of the fix commit (MERGEABLE-WITH-NITS) noted the headline L3 rethrow branch
itself had no test. Add a reader seam (internal ResolveKey Func overload) and two tests:
unreadable existing file throws + does not overwrite; a delete race between File.Exists
and the read falls back to generate rather than failing boot.

Cold adversarial review of PR #292 = MERGEABLE-WITH-NITS (no BLOCKER/HIGH). Addresses:
- M1: ApiKeyProvider's never-empty invariant was untested. Add ApiKeyProviderTests
covering WriteKey precedence, load-existing, empty-file regenerate, generate+persist,
0600 mode, and still-usable-key-when-persist-fails. ResolveKey extracted to an
internal seam taking the key path (InternalsVisibleTo ErsatzTV.Tests).
- L2: write-then-chmod race — the key was briefly world-readable. Persist now creates
the file 0600 atomically via FileStreamOptions.UnixCreateMode (then re-asserts).
- L3: a transient read error on an EXISTING key file silently regenerated + clobbered
it (invalidating every client key). ResolveKey now rethrows on an unreadable existing
file (fail loud) and only regenerates when the file is absent or empty.
L4 (LocalhostOnly XFF-spoof under default trust-all) and N5 (length oracle on a
fixed-width key) accepted as documented/cosmetic.

Cold-review LOW (defense-in-depth): the serve path derived the Content-Type
from the stored file via Winista but only defaulted application/octet-stream on
a NULL sniff. A cache file whose bytes are HTML — a legacy entry poisoned before
the upload-sniff landed, or a hypothetical image/script polyglot — could still be
sniffed as text/html and served renderable (nosniff does not stop an explicitly
declared text/html). Clamp the sniffed type to ImageContentTypes.IsAccepted,
serving application/octet-stream for anything else, so the serve path can never
emit a renderable non-image type regardless of what bytes are on disk.

S4 stored-XSS + S9 upload-size DoS from the #197 cold API review.
The artwork path trusted client-supplied content types at both ends: upload
validated only the declared multipart Content-Type (never decoded the bytes),
and serving reflected a client `?contentType=` straight into the response
Content-Type on unauthenticated GET sinks (/iptv/logos, /artwork/watermarks).
Chain: upload <script> bytes as image/png -> GET ...?contentType=text/html
serves them as HTML in-origin. nosniff (#279) does not help because the server
explicitly declares text/html.
- Upload: derive the content type from the bytes via SkiaSharp SKCodec
(header-only, no decode -> no decompression-bomb path); reject non-images 422.
New ErsatzTV.Core/Images/ImageContentTypes as the single allow-list source.
Dropped the untrusted declared Content-Type from the UploadArtwork command.
- Serve: removed the ?contentType= reflection structurally -- dropped ContentType
from GetCachedImagePath and the [FromQuery] binding on GetImage/GetWatermark;
the handler always sniffs the file, defaulting application/octet-stream.
ArtworkContentTypeModel.UrlWithContentType is now the bare path; SPA previews
no longer append the query.
- Defense-in-depth: channel-logo / watermark {path, contentType} DTOs run through
ArtworkContentTypeModel.Sanitized(), blanking non-allow-listed types on write.
- S9: Kestrel MaxRequestBodySize from ETV_MAXIMUM_UPLOAD_MB rejects oversized
bodies during read (controller file.Length check kept as friendly-error backstop).
Both serve sinks are IgnoreApi, so no OpenAPI change. Tests: byte-sniff accept/
reject, Sanitized() allow-list, Location no longer carries ?contentType=.

Backend of #197 Bundle A (auth posture). Owner decisions: single API key;
Api:RequireKeyForReads defaults true (whole /api surface gated; /iptv streaming
+ guide unaffected — outside the filter's /api scope).
- #280 S1: writes are fail-closed. New IApiKeyProvider resolves the key once
(Api:WriteKey config, else persisted /config/api.key, else a generated 256-bit
key written 0600). The empty-key open branch is gone; there is no open mode.
- #282 S3/S5: reads under /api require the key when Api:RequireKeyForReads (default
true) or the endpoint carries the new [RequiresApiKey]. Applied [RequiresApiKey]
to Troubleshoot/Logs/Settings/Maintenance so the sensitive tier stays gated even
if reads are opened. OPTIONS preflight is exempt.
- #281 S2: delete SortController (dead Blazor SortableJS residue; SPA uses PUT
/api/collections/{id}/custom-order) and AccountController (dead OIDC logout) —
both non-/api persistent surfaces that bypassed the key.
- #284 S6: replace CORS AllowAll with an opt-in exact-origin allowlist
(Api:CorsAllowedOrigins; permits X-Api-Key/If-Match, exposes ETag). Default is
no cross-origin (SPA is same-origin).
- #285 S7/S10: gc GET->POST (spec regenerated); ForwardedHeaders trust configurable
via ForwardedHeaders:KnownProxies/KnownNetworks (warns when unrestricted);
ScannerController gains [LocalhostOnly] (scanner always calls back over localhost).
Filter unit tests rewritten for fail-closed + read-gating + tier + OPTIONS;
ApiControllerSecurityTests assert the sensitive tier + scanner-loopback reflectively.
search/all-items paging deferred (SPA add-all coupling) — exposure closed by read-gating.

Bundle A SPA slice: the /api surface is now gated behind X-Api-Key on
every request (reads too, RequireKeyForReads defaults true), so a wrong/
missing key 401s everything.
- #282: send X-Api-Key on ALL requests when a key is stored, not only
mutations (removed the mutatingMethods split in api/client.ts).
- #280: new keyless API Key screen (/app/api-key, System nav) that reads/
writes only localStorage via auth.ts and never calls /api, so it works
on a fresh install where every read 401s. Masked key state, Save/Clear,
points at server-generated /config/api.key.
- 401 UX: client emits one app-wide unauthorized signal (auth.ts
notify/subscribeUnauthorized); a shell-level UnauthorizedBanner points
the user at the API Key screen. DRY, no per-screen 401 branches.
- Tests: inverted the GET header assertion (key now sent on reads), added
no-key and 401-signal client tests, auth signal tests, and screen +
banner tests. spa-conventions.md §5e documents the new seams.

Follow-up to PR #279 — the adversarial diff review flagged that adding
baseline security headers to every response is an operational-behavior
decision worth a decisions.md entry. Records the SecurityHeadersMiddleware
placement + the deliberate CSP/HSTS deferral to the #197 posture design,
plus the constant-time key compare and playout paging clamps.

Posture-independent safe hardening from the #197 cold API security review
(the clear-cut fixes that don't depend on the fail-closed/CORS/versioning
posture design, which is tracked separately):
- ApiKeyAuthorizationFilter: compare X-Api-Key with
CryptographicOperations.FixedTimeEquals instead of ordinal string.Equals
(removes the response-timing oracle on the write key). [S10]
- PlayoutController: clamp pageNum/pageSize on GET /api/playouts and
/api/playouts/{id}/items to Math.Clamp(_, 1, 100), matching the documented
api-conventions §1 convention every other paged endpoint already follows —
these two were passing the raw value straight to EF Take(). [S8]
- SecurityHeadersMiddleware: emit X-Content-Type-Options: nosniff,
X-Frame-Options: DENY, Referrer-Policy: strict-origin-when-cross-origin on
every response (nosniff backstops the artwork content-type MIME-sniffing
risk). CSP/HSTS deferred to the #197 posture design (CSP needs SPA
validation; HSTS is proxy/TLS-owned). [S10]

Timothy reversed the version-pin decision: prod's media-servers compose now
follows the floating :prod tag, redeployed by Komodo Global Auto Update. The
bump-prod-compose job (#275) rewrote a :<version> pin, which would flip :prod ->
:26.8.0 on the next release — remove it. docs/ci-cd.md reconciled to the :prod
model (+ flags the open caveat: verify Global Auto Update runs the #553
pre-deploy backup, else releases deploy without a backup).

Review-caught coverage gap: the existing Subtype_Change test runs the POSITIONAL
path (id-less payload). Add a handler-level test for the id-mode branch — one
id-matched item changes subtype (One->Duration: delete+insert, new id) while a
sibling id-matched item keeps its subtype (Multiple: in place, id + fill-group
state preserved) in the same payload. Proves the delete pass + match-pass Remove/Add
don't double-handle and the survivor's state is retained.

Add the id-based reconcile tests to ReplaceProgramScheduleItemsReconcileTests:
reorder moves state with the logical item (the non-vacuous core — proven to fail
under forced-positional), insert-in-middle, delete-unreferenced, unknown-id→422,
duplicate-id→422, and stale-version+unknown-id→412 (412 precedes 422, §7c). The
GET→map→PUT lossless round-trip now round-trips r.Id so it exercises id-mode.
Threads the new int? Id through all command/wire construction sites in tests.
Docs: api-conventions §7c (stable child identity + the deliberate #2-#5 positional
asymmetry) and a decisions.md entry.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The backend (already on this branch) added an optional int? Id to
ScheduleItemRequest so the server reconciles PUT /api/schedules/{id}/items
rows by identity instead of by array position. The SPA previously
discarded the server id on load (only a client-local _key survived) and
never sent one back, so a reorder could misattribute fill-group/shuffle
state onto the wrong persisted row.
- itemRules.ts: fromResponse now captures the response item's id onto
the draft; normalizeForSave emits it back unchanged. newDraftItem and
copyDraftItem explicitly set id: null (a brand-new/copied row was
never persisted under an id, and copyDraftItem must not duplicate the
source's id onto a second row).
- scheduleItem.ts (Add-to-schedule dialog, POST path): id: null for the
same reason — it always creates a new row.
- SchedulesScreen.tsx save(): the PUT-response re-seed already existed
(fromResponse over the response array) but now carries ids through.
This matters because a subtype/playout-mode switch can be a
delete+insert server-side, so the response id for that row can differ
from what was submitted — a second save must use the *response's* id
or the server 422s it as unknown. Added a comment documenting this.
- schedules.ts: replaced the stale "server reuses same-typed rows by
position" comment with the current id-based reconcile contract.
- Added/updated tests in itemRules.test.ts, SchedulesScreen.test.tsx,
and AddToScheduleDialog.test.tsx covering id round-tripping, the
null-id-for-new/copied-item cases, and a second-save-reuses-the-
response-id regression test.
Verified: npm run lint, tsc -b --noEmit, npm run build, and npm test
(680/680) all pass.

The auto-pin-to-prod job designed on the unmerged `ci/auto-bump-prod-compose`
branch (3d6ac883) never landed on main — so v* releases (v26.5.0, v26.6.0) did
NOT auto-bump the server-management compose pin (it sat at 26.5.0). The docs
(homelab-docs Docker/ErsatzTV.md, ci-cd.md) described the auto-bump as if live.
Restore the job verbatim (its credentials already exist: the `ersatztv-ci-deploy`
write deploy key, id 5, on server-management + the SERVERMGMT_DEPLOY_KEY secret
here). On a v* tag, after the test-gated image builds, it rewrites the pinned
`ersatztv:<version>` tag in docker/bumblebee/stacks/media-servers/compose.yaml
and pushes to server-management `master` → the Gitea->Komodo webhook redeploys
prod with a pre-deploy backup. Idempotent (no-op if already pinned).
docs/ci-cd.md updated to match (release procedure + the stale ":prod pin" claim,
which was actually an immutable :<version> pin since 2026-07-07).

Add optional `int? Id` to ScheduleItemRequest/ReplaceProgramScheduleItem so
a client can round-trip each existing item's server id. When ids are present,
ReplaceProgramScheduleItemsHandler reconciles by id (not array position), so an
item's persisted fill-group/shuffle state (PlayoutScheduleItemFillGroupIndex,
FK OnDelete Cascade) follows the logical item across reorders/inserts instead of
being inherited by whatever previously occupied its new slot (#259, split from
#252/#253). A fully id-less payload keeps the verbatim positional fallback.
Guards (inside PersistItems, after CheckVersion so 412 precedes 422): duplicate
id -> 422; id not in this schedule -> 422 (a stale id under Phase-1 force-write is
a live lost-update signal, not a new item). Index stays array-position derived.
Regenerated v1.json + TS client.

Cold-review Low-1: ErsatzTV/Extensions/NavigationManagerExtensions.cs survived
the removal — the last non-deleted .cs still importing
Microsoft.AspNetCore.Components/JSInterop and calling the deleted

The ChicoryTV React SPA (web/, served at /app) now has full parity for every
route the Blazor UI served, so the legacy Blazor Server / MudBlazor UI is
deleted. This is the milestone-capping removal of #91 phase (b).
Deleted: ErsatzTV/Pages/**, Shared/**, ViewModels/** (39 edit VMs),
Validators/** (10 edit-VM validators), App.razor, _Imports.razor,
Locals/{Shared,Pages}/** (Blazor loc resx; Locals/Resources.* kept),
wwwroot/css + wwwroot/lib, libman.json, and the orphaned MultiSelectBaseTests.
Startup.cs (surgical, not wholesale): removed AddRazorPages/AuthorizeFolder,
AddServerSideBlazor, AddMudServices, AddSortable, AddCourier, the HtmlSanitizer
registration, the Blazor-attached OIDC UseAuthentication/UseAuthorization
middleware (per the #206 auth-posture sign-off), MapBlazorHub, and
MapFallbackToPage("/_Host"). Renamed the branch blazor->legacy; it still
co-hosts MapControllers, /docs (Scalar), dev MapOpenApi and the redirect
middleware. Replaced the _Host fallback with a catch-all (MapFallback ->
302 /app) that excludes /api|/artwork|/docs|/openapi (genuine 404) per #204.
Kept all OIDC/JWT/API-key service wiring (inert unless configured; real auth
is #197), ConditionalIptvAuthorizeFilter, ApiKeyAuthorizationFilter.
Pruned 9 now-unused packages (all verified zero remaining consumers) from
Directory.Packages.props + ErsatzTV.csproj: MudBlazor, Heron.MudCalendar,
Blazored.FluentValidation, BlazorSortable, MediatR.Courier.DependencyInjection,
Markdig, HtmlSanitizer, Chronic.Core, NaturalSort.Extension. Also removed the
now-dead #25 razor-Sonar NoWarn.
LegacyUiRedirects: added the 14 /media/sources/* -> /app/libraries/* redirects
(SPA screens landed in #202) and lifted the #204-era /media/sources prefix ban.
Tests: Release build clean; full solution suite green. Updated Startup
source-text tests + added regression coverage that Blazor wiring is gone, the
catch-all is wired, and all 14 media-sources routes redirect.
Docs: blazor-route-parity.md (phase b COMPLETE), decisions.md (removal entry),
CLAUDE.md, contributing.md, README.md all updated in this PR.
Rollback: tag blazor-final is cut on pre-merge main as the first merge action.
Part of #91.

Adversarial review caught a HIGH the fan-out introduced: activating Version as an
IsConcurrencyToken on Playout/Collection makes EF append `WHERE Version=@orig` to
EVERY root UPDATE, so a non-If-Match writer that saves via plain SaveChangesAsync
now throws DbUpdateConcurrencyException → 500 when a replace-all editor bumps the
row between its load and save. Realistic two-tab trigger (edit playout settings while
editing its alt-schedules; edit a collection's name while reordering) — a new crash,
previously silent last-write-wins.
Fix: shared ConcurrencyExtensions.SaveChangesForcingVersion — on a concurrency
failure it adopts the stored token as original+current (client-wins merge scoped to
the token, never reverting the concurrent bump) and retries, i.e. Phase-1 force-write
semantics for a missing If-Match. Applied to the exposed UPDATE writers:
UpdatePlayout, Update{Sequential,Scripted,ExternalJson}Playout, UpdateOnDemandCheckpoint,
UpdateCollection. Non-vacuous test proves the write lands and the bump survives.
Deletes + repo-mediated Add* writers (rarer / join-rows-only) re-scoped onto #269.

Installs husky git hooks (via web/'s lint-staged + npm, since the JS/TS
project lives in web/ with no root package.json) to catch lint, format,
type, and generated-API-drift errors locally before they reach CI.
Hooks (committed at repo root under .husky/):
- pre-commit: (a) lint-staged runs eslint --fix on staged
web/src/**/*.{ts,tsx} + a project-wide typecheck; (b) if any *.cs are
staged, dotnet format --verify-no-changes on just those files (skipped
when no .cs staged, so web-only commits skip the sln load).
- pre-push: CI-parity gate — cd web && check:api && lint && typecheck &&
build. Blocks pushing drift or a change that breaks an unstaged file.
- commit-msg: requires a Co-Authored-By trailer (merge commits exempt).
Wiring: web/package.json gains husky + lint-staged devDeps, a lint-staged
config, and a `prepare` script (cd .. && husky) that points git's
core.hooksPath at the repo-root .husky dir on npm install. A fresh
`web/` npm install installs all four hooks automatically.
Monorepo/worktree gotchas handled:
- husky init hard-checks for .git in cwd, so `prepare` cd's to the repo
root before invoking husky (npm keeps web/node_modules/.bin on PATH).
- git exports GIT_DIR while running hooks; in a worktree/subdir that made
pre-push's `git diff` (check:api) mislocate the working tree and pass
silently on drift — pre-push now unsets GIT_DIR/GIT_WORK_TREE/GIT_INDEX_FILE.
docs/ci-cd.md: new "Pre-commit hooks (web/)" section covering all four.
Verified: eslint error blocks commit; clean commit passes; bad-format .cs
blocks (dotnet format ~6-7s scoped), good .cs passes; check:api drift and
a lint error each block `git push --dry-run`, clean state passes; missing
Co-Authored-By blocks commit-msg, present passes; non-web/.cs commits skip
lint/format. npm run lint clean.

Last SPA pre-work before deleting Blazor Libraries.razor (#91 phase b):
wire the shipped scanLibrary(id, deep) + scanCollections(family, id, deep)
clients (F9 API, #235) into LibrariesScreen so the SPA reaches parity with
Libraries.razor's four scan actions.
- Deep Scan Library button on each remote (Plex/Jellyfin/Emby) library row,
threading `deep` through the existing optimistic-pending/poll hook (quick +
deep share the per-library lock).
- External Collections section (quick + deep per remote source). Rows derive
client-side from getMediaSources(): the media-sources API handler already
filters each source's `libraries` to sync-enabled entries, so a remote
source with a non-empty libraries list is exactly GetExternalCollections's
Libraries.Any(ShouldSyncItems) filter — no new endpoint.
- useCollectionsScan hook: collections scans have no scan-status poll surface
(the endpoint is library-keyed; Blazor observed collections locks via
in-process IEntityLocker events), so pending is optimistic + timeout-bounded
(409 benign, 404/network surfaces the error). Follow-up #271 for a proper
collections status surface.
Pure SPA change (no backend/OpenAPI). Docs: blazor-route-parity.md §5 (SPA
affordance DONE), decisions.md (derive-vs-endpoint + optimistic-timeout).

The prior fix set setItemsLoading/setItemsLoaded at the top of loadItems, but the
activeId effect calls loadItems synchronously → react-hooks/set-state-in-effect lint
error (Main Lint SPA, the real CI failure). Move the not-loaded/loading gating into
reloadAfterConflict (an event handler, lint-clean), which is exactly the 412 conflict-
reload path Codex's Medium-3 targeted; canEdit stays false through that reload window.
Behavior unchanged; the normal switch/initial-load paths (guarded separately by the
#242 dirty-guard) are left untouched. Local: lint clean, vitest 667, check:api no drift,
full dotnet solution test green.
Independent Codex review of #268 found two Blockers the fork missed + two Mediums:
- Blocker: replace PUTs returned the handler's item snapshot but re-queried the root
for the ETag separately, so a racing writer could pair stale items with a newer ETag
(silent overwrite). All four controllers now reload root-then-items (version-first,
fail-safe) and 404 when the root is gone between commit and reload — matching the
Block reference. Fixes the Blocker + the Medium '200 without ETag' case together.
- Blocker: PlaylistsScreen loaded items+root via Promise.all (concurrent), pairing a
stale name with the current ETag; now sequential (items-with-meta first, then root).
- Medium: SchedulesScreen loadItems now marks not-loaded/loading up front so canEdit is
false through the 412 conflict reload (no stale-draft edits lost).
Controller unit-test mocks updated to stub the new reload query. Full suite green
(ErsatzTV.Tests 1334, web 667, check:api no drift).
Codex-review Low: NotFound previously reached the catch-all by coincidence; a
future enum value would silently 404. Explicit arm + UnreachableException fallback
so an unmapped outcome fails loudly rather than mis-mapping to 404.
