Active decisions — catalog / task router

The compact current view of settled decisions. Each row is an active record; follow the link for rationale. Superseded/retired history lives in archive/. Regenerated by scripts/build_decisions_catalog.py.

Key	Current rule	Since	Record
api.artwork-rooted-urls	API response DTOs return artwork as rooted, directly-usable URLs (plus passthrough for absolute/proxy URLs), never relative Blazor-convention paths.	2026-07-07	link
api.async-op-contract	Queue-triggering /api/* endpoints normalize onto one contract — 202 Accepted (queued), 404 (missing entity), 409 (lock held), 422 (domain precondition) — with Trakt as the reference implementation; playout list/detail GETs also carry an isLocked observability flag as the HTTP-observable substitute for a live push channel.	2026-07-11	link
api.channel-health-object	ChannelResponseModel/ChannelDetailResponseModel carry a server-derived health object (ChannelHealthResponseModel { Status, Faults[], PlayoutCount, BrokenSourceItemCount }) computed read-time from the built timeline (Playout.BuildStatus + upcoming PlayoutItem → MediaItem.State, Finish >= now), kind-agnostic across all 5 PlayoutScheduleKind values; Status/Faults are const-string classes (ChannelHealthStatus, ChannelFault), not C# enums, so the SPA hand-maintains the union (mirrors ChannelPreviewAvailability). This supersedes #72's "raw fact only, no derived enum, empty-schedule/broken-source deliberately not computed" stance now that the auto-tune taxonomy churn (#383/#384) it was waiting on has landed (see channel.origin-marker sibling record, #414).	2026-07-23	link
api.channel-preview-capability	Whether a channel can be previewed in the browser is declared by the server, not derived by the SPA, as an additive Preview field ({Availability, ManifestUrl, UnavailableReason}) on ChannelResponseModel.	2026-07-21	link
api.decode-by-id	Endpoints that decode/expand opaque stored state accept a database row id and resolve it server-side rather than round-tripping client-supplied serialized state.	2026-07-07	link
api.from-lineup-clear-to-none	POST /api/v1/channels/from-lineup (and the Auto-Tune per-channel advanced, which reuses the same DTO) distinguishes inherit from clear-to-none with a typed clear enum list on advanced. A field left null/omitted still inherits the template value (unchanged for every existing client); naming a field in clear forces it to none on the new channel even when the template sets one. Sending both a set value and a clear for the same field is a validation error.	2026-07-21	link
api.healthcheck-remediation-dto	Health-check remediation is server-declared {Kind, Target} metadata on an additive DTO field; the SPA renders/acts on it, it doesn't derive labels itself.	2026-07-17	link
api.healthcheck-ttl-cache	Health-check results are held in a 30s TTL cache inside HealthCheckService; a non-forced GET /api/v1/health returns the cached list, and ?refresh=true (or a forced internal caller) bypasses it to run fresh.	2026-07-19	link
api.logs-sort-params	GET /api/logs takes allow-listed sortField (timestamp|level) and sortDirection (asc|desc) query params, normalized (not rejected) on an unrecognized value.	2026-07-11	link
api.mediatr-passthrough	The REST API is thin controllers over existing MediatR handlers, with no new service/business-logic layer.	2026-06	link
api.openapi-mirrors-runtime	The generated OpenAPI spec is made to match the runtime Newtonsoft wire contract (via NewtonsoftSchemaNamingTransformer), not the reverse.	2026-07-09	link
api.paging-zero-based	pageNum is 0-based across the entire /api/v1 surface and every wrapper of it (MCP tool catalog, SPA hooks, docs); the page offset is always derived from the EFFECTIVE (bounded) pageSize, never the requested one, so a pageSize above an endpoint's cap narrows the page without widening the offset. The cap itself is per-endpoint (100 typical, 200 auto-tune members, 1000 search/all-items) and must not be documented as one number. A paging parameter description that omits or contradicts "0-based" is a defect.	2026-07-25	link
api.parentid-drillin	Media drill-in (season/episode/artist/music-video) is served by an optional parentId query param on library-browse, not dedicated per-kind child-listing endpoints.	2026-07-07	link
api.playout-build-lock-409	Every id-keyed playout/channel mutation endpoint checks IEntityLocker.IsPlayoutLocked(id) and returns 409 Conflict while a build is in-flight, mirroring Blazor's disabled-buttons behavior; reset-all stays 202 and silently skips locked playouts.	2026-07-10	link
api.postcommit-cancellation-none	Once a mutation commits, its entire compensating side effect (enqueues, publishes, reindexes, cache refresh, and any post-commit lookup gating one of those) runs on CancellationToken.None so a late client disconnect can't half-abort an already-committed change.	2026-07-11	link
api.put-replace-index-order	PUT-replace-the-whole-list endpoints derive each item's Index from its request-array position, never a client-supplied field; alternate-schedule/playout-template rows are evaluated in Index order with the least-conditional row placed last as the catch-all default.	2026-07	link
api.response-dtos	New REST response DTOs live in ErsatzTV.Core/Api/<Domain>/*ResponseModel.cs with a file-scoped #nullable enable pragma; controllers never expose Application VM types directly.	2026-07	link
api.schedule-item-flat-dto	Schedule-item GET/POST/PUT use a flat, non-polymorphic ScheduleItemResponseModel (every subtype field promoted to a nullable top-level member) instead of the polymorphic Application VM hierarchy, with mutation field names matching ScheduleItemRequest 1:1 for a lossless round-trip.	2026-07-10	link
api.scheduling-hardening	Create/Replace handlers guard against null/whitespace name (IsNullOrWhiteSpace, not just Length) to prevent NRE-500s, template-item overlap validation compares by index (not record value-equality) to catch exact-duplicate items, and unreachable 404 ProducesResponseType attributes on create-only actions are trimmed.	2026-07-13	link
api.search-allitems-paging	GET /api/v1/search/all-items is paginated (capped page size, Totals field) to bound DoS exposure; the SPA add-all flow pages to completeness instead of relying on an unbounded response.	2026-07-18	link
api.search-field-values	GET /api/v1/search/fields/{name}/values?q=&limit= returns distinct WHOLE values from the database for one of a narrow allow-list of catalog fields (not the Lucene term dictionary — analyzed TextFields store lowercased word tokens, e.g. "Science Fiction" → science/fiction, useless as a typeahead suggestion), 404 for an unknown field, a non-text field, or a text field with no distinct-value source; case-insensitive prefix-filtered on q, limit clamped to [1, 50] (default 50).	2026-07-23	link
api.search-paging-cap	Search stays capped at 100 items per media kind; an overflowing kind's "See all" reuses library-browse paging instead of adding new API surface.	2026-07-11	link
api.versioning-v1	The entire /api surface is versioned to /api/v1 uniformly (no unversioned corner); legacy unversioned callers are rewritten in-pipeline (not redirected) with Deprecation/Link/Sunset headers, and post-freeze /api/v1 is additive-only — a breaking change requires /api/v2.	2026-07-13	link
blazor.rollback-tag	The commit immediately preceding the Blazor-removal merge is tagged blazor-final (not a v* tag, so it doesn't trigger a prod release build) as the documented rollback/restore path.	2026-07-11	link
blazor.ui-removed	The legacy Blazor Server UI (Pages/, Shared/, ViewModels/, Validators/, MudBlazor + 8 other packages, Blazor Startup wiring) is fully deleted now that the SPA has parity; the legacy MapWhen branch is kept only for controllers/docs/OpenAPI/LegacyUiRedirects, and the catch-all fallback 302s any unmatched non-api/artwork/docs/openapi path to /app.	2026-07-11	link
channel.origin-marker	A new Channel.Origin (ChannelOrigin enum — Unknown/UserCreated/AutoTuned) records how a channel row was created and is stamped exactly once at insert (AutoTuned in CreateChannelFromLineupHandler, UserCreated in CreateChannelHandler), and is never mutated on a later edit. It is surfaced as a raw origin field on ChannelResponseModel; the SPA badges only AutoTuned. Rows predating the column read Unknown — provenance is not back-filled.	2026-07-23	link
ci.batch-pushes-no-cancel-route	Hold review fixes, doc corrections and format fixes locally and push once — a superseded run cannot be cancelled from the agent side and holds a runner slot until it finishes.	2026-07-21	link
ci.build-once-rejected	CI build-once (a shared compile artifact across jobs) was implemented, measured, and rejected for a 40-85% wall-clock regression; keep the #420 cross-run tree-identity skip instead.	2026-07-18	link
ci.cancelled-is-not-a-verdict	Treat a cancelled conclusion as "no verdict" — never as pass or fail — and report FAILED and CANCELLED counts separately in any CI monitor.	2026-07-21	link
ci.decisions-edit-trailer	The body-diff exemption is armed by an affirmative Decisions-Edit: git trailer (yes/true/1, case-insensitive, read with unfold) on some NON-MERGE commit in the PR's merge-base range — never by a substring search over the message text. A non-affirmative value (no) does not arm it, the retired [decisions-edit] substring arms nothing (the validator emits a ::warning:: nudge when it sees one without a trailer), and a git error leaves the guard ON.	2026-07-25	link
ci.decisions-lifecycle-flake	When decisions lifecycle is the only red job, do not investigate and do not create a new run to clear it — no rebase, no --amend, no no-op push; the operator reruns that single job from the Gitea UI.	2026-07-21	link
ci.docs-only-detect-shallow-safe	The docs-only detect script must diff against FETCH_HEAD (always resolves after git fetch, even shallow) using a two-dot tree diff — not origin/<base> with three-dot — because a fetch-depth: 1 shallow clone has no remote-tracking ref and no merge-base, which silently fails the original detect into docs_only=false (full matrix, no functional error). A CI-behavior change must be verified by measuring the effect (job durations), not just a green check.	2026-07-17	link
ci.docs-only-skip-steps	A docs-only change must still run every required job (test, migrations) so their commit-status contexts always report; each heavy job runs scripts/ci-detect-docs-only.sh first and gates its real STEPS on if: steps.detect.outputs.docs_only != 'true', never if:-skips the whole job (an if:-skipped job reports skipped, not success, which branch protection may never unblock on). Detection biases toward running more on any doubt.	2026-07-17	link
ci.format-gate-folder-mode	The blocking format CI job (and matching pre-commit hook) runs dotnet format whitespace . --folder --include <files> instead of loading the full MSBuild/Roslyn solution, cutting the gate from ~480s to ~0.5s with unchanged whitespace/charset coverage.	2026-07-19	link
ci.functional-e2e-harness	The functional-e2e CI job boots the PR's own code from source via dotnet run (scripts/e2e-local.sh) and runs deterministic assertions (scripts/e2e-functional.sh) as an advisory (non-blocking) job, not a build dependency or required check. Originally curl-only; since #445 the same job carries a second, headless-browser step for the contracts curl cannot express — see ci.ui-e2e-harness.	2026-07-16	link
ci.gitea-milestone-filter-noop	Never filter issues with the server-side ?milestones=<name> parameter — fetch all open issues once and filter LOCALLY on each issue's .milestone.title.	2026-07-21	link
ci.infra-shaped-red-under-load	When a job dies inside a setup/cache step before your code compiles, check the runner host's load before diagnosing the diff, and never file a CI bug off one sample under pressure.	2026-07-21	link
ci.killed-job-triage	Never trust a job's conclusion field alone — read the log tail and require an ❌ Failure - Main … marker before treating a red as a real failure.	2026-07-21	link
ci.monitor-armed-at-pr-open	Arm a CI monitor on the PR head sha the moment the PR opens, polling the commit-status endpoint — not at the end of the work.	2026-07-21	link
ci.no-host-health-gating	Push when your work is validated — never SSH to bumblebee to sample load/RAM first, and never hand-schedule around other sessions' runs.	2026-07-21	link
ci.peak-anon-measurement	The test job's headline memory figure is a sampled high-water mark of cgroup anon, produced by scripts/ci-peak-anon.sh; memory.peak and the end-of-job anon/file split are kept only as a cache-inflated reference.	2026-07-19	link
ci.root-screenshot-guard	The Husky pre-commit hook refuses a staged root-level *.png (belt-and-suspenders with the .gitignore rule); nested *.png real assets are unaffected.	2026-07-12	link
ci.runner-placement	No persistent Roslyn compiler server survives a CI build (UseSharedCompilation=false etc., runner env + Dockerfile ENV); every services: container gets its own explicit --memory/--memory-swap/--cpus cap (it does not inherit the job container's).	2026-07-17	link
ci.script-tests-job	The scripts/tests/ pytest suite runs on every PR as a dedicated script-tests job in pr-checks.yml (runs-on: small, setup-python + pip install pytest, PYTHONPATH=. python3 -m pytest scripts/tests -q), unconditionally rather than behind a scripts/** path filter, and never as a step inside decisions-guard — a job whose reds a standing rule instructs sessions to ignore must never host a gate whose reds are real. Any new CI gate must be reachable by a failure that is unambiguously attributable to it.	2026-07-26	link
ci.small-lane-git-only	runs-on: small is defined by what a job does (git-only), not its usual runtime; the two docker build jobs (docker-build.yml, ci-image.yml) move to ubuntu-latest because their worst-case memory, not median runtime, was pinning the small lane's per-slot cap.	2026-07-20	link
ci.ui-e2e-harness	The UI-interactive E2E flows run as headless Playwright specs (web/e2e/*.spec.ts, driven by scripts/e2e-ui.sh) in a second step of the existing advisory functional-e2e job, never their own job; the browser is chromium-headless-shell baked into the CI toolchain image (docker/ci/Dockerfile, PLAYWRIGHT_VERSION kept equal to web/package.json's EXACT @playwright/test pin), never installed per run; specs are serial with retries: 0 and assert only contracts the curl harness structurally cannot reach.	2026-07-25	link
ci.verify-locally-ci-confirms	Treat the local build/verify/review pass as the decision point and CI as confirmation — don't idle waiting on a run you have no reason to doubt.	2026-07-21	link
ci.web-test-per-test-timeouts	Give heavy-render web tests an explicit per-test vitest timeout (e.g. 15s); never raise the global default to fix one slow test.	2026-07-21	link
concurrency.diff-scalar-fanout	The frozen Block optimistic-concurrency recipe (api-conventions §7a) fans out to Collection/Playout×2/MultiCollection/RerunCollection, keeping a guard-returned PreconditionFailedError out of any handler's generic catch(Exception)→422 mapping, and preserving each aggregate's existing SaveChangesAsync() > 0 gate semantics under the new unconditional Version++.	2026-07-11	link
concurrency.etag-rotation-completion	Every handler that mutates a versioned root's editor-visible config state must bump Version (rotating the ETag) with no per-aggregate carve-outs, short-circuiting on a genuine no-op before the bump so idempotent re-submits don't fire spurious rebuild fan-out; SaveChangesForcingVersion rebases the retry (stored + pending delta), never adopts the stored token verbatim.	2026-07-12	link
concurrency.force-write-non-ifmatch	Any handler that leaves a versioned root Modified or Deleted but takes no If-Match (deletes, item add/remove bumpers, scalar-config writers) must save through ConcurrencyExtensions.SaveChangesForcingVersion — force-write past a concurrent Version bump rather than throw an unhandled DbUpdateConcurrencyException (500).	2026-07-12	link
concurrency.idempotent-concurrent-add	A concurrent duplicate Add*ToCollection that loses the race on the composite-key unique constraint is treated as an idempotent no-op (skip the reindex/rebuild fan-out), not a 500 — detected via a provider-specific TvContext.IsUniqueConstraintViolation delegate defaulting to "no".	2026-07-18	link
concurrency.ifmatch-rfc7232	ConcurrencyHeaders.ParseIfMatch is a real RFC 7232 entity-tag/list parser: a syntactically-valid tag that doesn't strong-match (weak/empty/non-canonical/out-of-range/list) returns 412, and only a genuine grammar violation returns 400.	2026-07-12	link
concurrency.replace-all-contract	Replace-all aggregate PUTs carry a uniform plain int Version concurrency token (EF .IsConcurrencyToken()), checked pre-save and enforced by the EF UPDATE guard, returning 412 (not 409) on a stale If-Match.	2026-07-11	link
concurrency.schedule-item-child-identity	PUT /api/schedules/{id}/items reconciles by an optional round-tripped child Id (null/absent/0 ⇒ new item), never by array position, so fill-group/shuffle state follows the logical item across reorders; an unknown or duplicate id is rejected 422 (checked after the §7a CheckVersion, so 412 precedes 422).	2026-07-11	link
docs.convention-docs-session-start	Docs-first, not source-first: conventions (api-conventions, spa-conventions, e2e-local, blazor-route-parity, domain-model, decisions, README) are read from docs, not reverse-engineered from code, via docs/README.md's task-signal map — only the sections it points to for the task at hand, not the whole set. Each doc is updated in the same PR that changes what it documents, replacing deferred/follow-up doc updates.	2026-07-07	link
docs.corpus-size-signal	The corpus's size signal is a per-record prose ceiling (decisions_validate.py --record-ceiling, default 60, chosen at a natural gap in the distribution), reported as a NON-BLOCKING ::warning:: naming each record over it. The aggregate prose total is still printed every run but carries NO threshold — it is a ::notice:: trend only — because a total over a monotonically growing corpus can only ratchet, and the generated catalog (docs/decisions/README.md) is no longer counted at all since it gains one row per record and cannot be consolidated away. Being listed by the ceiling is an invitation to check for REDUNDANCY, never an instruction to cut: a long record that is all distinct findings is a legitimate decline, and should be recorded as one.	2026-07-26	link
docs.decision-lifecycle	every decision ## record (active or archived) carries a 5-field metadata block (key, status, since, supersedes, superseded-by) checked by scripts/decisions_validate.py; a record is never deleted or line-edited to reverse a call — it is moved to docs/decisions/archive/ with status: superseded/retired and a reciprocal superseded-by/supersedes key pair to its replacement.	2026-07-21	link
docs.decision-one-file-per-record	Each decision record is its own file at docs/decisions/records/<area>/<topic>.md (archived ones at docs/decisions/archive/<area>/<topic>.md) with YAML frontmatter; the filename IS the key, so one-active-record-per-key is a filesystem property rather than a validator check, and supersession is a git mv.	2026-07-25	link
docs.decision-optional-provenance	Decision records gain two OPTIONAL fields — stale-after: YYYY-MM-DD on the metadata line and a **Sources:** line in the metadata block; the Open Knowledge Format (OKF) itself is NOT adopted as the record format.	2026-07-25	link
docs.record-wing-parse-guard	decisions_validate.py asserts, per PATH, that every *.md under docs/decisions/records/** and docs/decisions/archive/** parses to exactly one record carrying a key — an ERROR, not a warning, since a file in the record wings that is not a record is a mistake by definition. A file sitting DIRECTLY in archive/ is exempt only when it actually looks like a #610 stripped index — exactly one keyless record with a known generated heading — never merely by living there. The one other exemption, archive/README.md, is by exact RELATIVE PATH; nothing is ever exempt by BASENAME, since that would exempt the same filename in the active wing too. _read_frontmatter is deliberately NOT extended to accept YAML block scalars: every record value goes on ONE line, and the structural check is what makes that limitation loud instead of silent.	2026-07-26	link
docs.tracker-comment-retrofit	When the knowledge exporter flags an over-cap tracker issue and excludes it from ingestion, triage its comments instead of assuming a retrofit is owed — and for each decision-shaped item check the worked issue first, because a tracker session comment is by construction a précis of the fuller closing record posted on the issue it narrates. Applied to #237 (111 comments) this yielded zero records, so server-management#642's "a fact found only in a #237 comment" retrieval row has no valid subject and its interim target (an already-migrated record) is permanent.	2026-07-21	link
ffmpeg.external-logo-graphics-engine	External-URL channel logos pass through to the graphics engine like any other watermark source; WatermarkSelector must never gate them on File.Exists (always false for a URL) and never route them through the ffmpeg-native overlay shortcut.	2026-07-20	link
ffmpeg.hls-cold-start-burst	HLS cold-start latency is fixed with a bounded -readrate_initial_burst (gated on FFmpeg ≥6.1 capability detection), not by raising work_ahead_limit, which would remove the concurrency guarantee it exists for.	2026-07-20	link
ffmpeg.qsv-decode-encode-split	QSV decode is decoupled from QSV encode via a single FFmpegProfile.QsvPreferNativeDecoder bool (default ON, Linux-only), so a QSV encode profile can decode with the more tolerant native VA-API decoder instead of the QSV decoder, mirroring Jellyfin's hybrid decode/encode toggle instead of a general decode-family enum.	2026-07-20	link
ffmpeg.qsv-extra-hw-frames-floor	a QSV upload never emits extra_hw_frames below FFmpegState.MinimumQsvExtraHardwareFrames (64); a stored 0 or negative value is treated as "no pool configured" rather than honored literally, because with no headroom any unthrottled read exhausts the pool and the transcode writes nothing at all.	2026-07-21	link
ffmpeg.remote-image-fetcher-bounded	remote graphics-engine images are fetched through IRemoteImageFetcher with a pooled HttpClientFactory client, a body-covering deadline, a wire-transfer size cap, and a decoder-enforced DecoderOptions.MaxFrames bound re-verified post-decode — never cached, re-fetched per element init.	2026-07-20	link
ffmpeg.work-ahead-slot-atomic	workAheadSegmenterLimit is enforced by a single compare-exchange claim on a shared WorkAheadSlots pool taken by the caller of Transcode, which then passes ownership in and gets the release in Transcode's finally — never a Volatile.Read compare in one place and an Interlocked.Increment in another.	2026-07-21	link
ffmpeg.work-ahead-slot-release-never-negative	Release() reads the count and compare-exchanges current - 1 only when current > 0; a release against an empty pool records an unbalanced release and returns false without ever writing a negative value. It never decrements first and clamps afterward. The single caller (HlsSessionWorker.Transcode's finally) logs a warning on the false return.	2026-07-21	link
graphics.channel-level-attachment	A channel can attach GraphicsElements directly via a new ChannelGraphicsElement join table (a base layer under deco/playout-item elements), and a built-in text element (on-now-next.yml) is seeded once per database so the On Now/Next overlay works out of the box.	2026-07-22	link
graphics.channel-logo-caching	An external http(s) channel-logo URL is fetched, decode-budget-validated, and stored in the image cache under a content-hash name at SAVE time — becoming byte-identical to an uploaded logo — so the render path never fetches a logo over HTTP; a bad URL fails the save with a 422 (BaseError → ValidationProblemDetails).	2026-07-21	link
iptv.base-url	An optional advertised base URL (iptv.base_url) is resolved centrally via a pure Core helper (AdvertisedBaseUrl) inside the two IPTV generation handlers (M3U + XMLTV); unset/malformed values fall back byte-identical to the request-derived host, and it's a new iptv settings group distinct from ETV_BASE_URL and out of scope for HDHomeRun.	2026-07-16	link
iptv.logo-drives-bug-preset	One uploaded channel logo drives both the listing logo and the on-screen bug via a shared, seeded ChannelLogo-sourced watermark preset (Channel Bug), not new per-channel schema.	2026-07-20	link
locking.entitylocker-atomic-flags	EntityLocker uses Interlocked.CompareExchange-guarded atomic flags plus a documented single-owner-release discipline (no owner tokens/leases); Unlock* on an already-unlocked slot returns false and logs a Warning rather than throwing.	2026-07-11	link
mcp.server-foundation	ErsatzTV.Mcp is a fresh stdio JSON-RPC server wrapping frozen /api/v1 with explicit narrow per-endpoint tools, read-only-by-default enforced at runtime (ERSATZTV_ALLOW_WRITES), machine-key auth, and opt-in If-Match.	2026-07-20	link
media.lastscan-null-boundary	A never-scanned LastScan surfaces as null at the API/MCP boundary, not the 0001-01-01 MinValue sentinel — enforced by an ongoing read-boundary coercion plus a one-time data migration cleanup.	2026-07-18	link
media.remote-stream-probe	ValidatePlayoutItemPath probes the Plex/Jellyfin/Emby remote-stream URL via IRemoteStreamProber before returning it; only a redirected 404 fails closed (PlayoutItemNotAvailableFromMediaServer), everything else fails open, and there is no toggle.	2026-07-19	link
media.remote-stream-probe-externaljson	External-JSON playout channels' StreamRemotely now probes the remote-stream URL through the same IRemoteStreamProber seam as the generated-playout path, closing the #473 scope gap for a channel kind with no DB PlayoutItem rows.	2026-07-20	link
media.source-mgmt-write-api	Media-source management (local/Plex/Jellyfin/Emby) is a REST write API + SPA under /app/libraries/*, wrapping existing MediatR commands 1:1 with no new commands or DB migration; connection GETs never leak a stored apiKey, and each PUT-replace family's identity contract is documented per-family (not assumed uniform).	2026-07-11	link
process.bom-format-detection-recipe	Before any push touching .cs, detect BOMs with the xxd byte check and verify the format gate with dotnet format --include run under bash -c, never bare zsh.	2026-07-21	link
process.branch-off-feature-branch	To fix work on an unmerged feature branch, branch off that branch and land by fast-forward push — and after creating a worktree, drive the first Edit/Read from ITS absolute paths and git status it before building.	2026-07-21	link
process.build-concurrency-limits	Run at most 3–4 concurrent dotnet/npm builds on this Mac, gate launches on FREE RAM rather than CPU load, and never set ETV_UPDATE_GOLDENS / ETV_UPDATE_PLAYOUT_GOLDENS.	2026-07-21	link
process.codex-cheap-worker-launch	For bounded tool-bearing selector/recon work, launch a Codex worker with codex exec -m gpt-5.4-mini -c model_reasoning_effort=low -s read-only; spawn_agent buys parallelism but no cost savings.	2026-07-21	link
process.consistency-fix-new-code-scrutiny	Review a "make X consistent with Y" change as new code, not as a mechanical copy — and for any timer or effect involved, ask explicitly "when does this fire?", including on mount.	2026-07-21	link
process.enumerate-workaround-behaviors-before-deleting	When an issue says "delete X", enumerate every behavior X provided before removing it — a workaround often serves a second purpose that outlives the first.	2026-07-21	link
process.foreign-worktree-plumbing-merge	Never commit or merge inside a worktree another session created; land the merge with git plumbing against the branch ref instead.	2026-07-21	link
process.harden-with-runtime-posture-not-clamp	When a security fix constrains a capability the roadmap will later want, make the safe state the DEFAULT OF A SWITCH rather than a wall — and read the feature's own issue for its end-state first.	2026-07-21	link
process.independent-review-rubric	Run an independent review pass — preferably a different model family, otherwise a cold-context review-only agent — on any diff touching locks/concurrency, auth/security, API write-path handlers, or DB migrations, or larger than ~150 changed C# lines; skip only for a pure-SPA/docs leaf with no server-state effect, and state the skip and its reason in the PR or close comment.	2026-07-21	link
process.issue-qualification-audit	Run scripts/issue-qualification-audit.sh at session end and label everything it flags, including issues you filed that session.	2026-07-21	link
process.local-gate-before-push	Run the local build/test gate and a cold-context, scoped "review only" adversarial review over the diff, fold the fixes, and only then push or open the PR.	2026-07-21	link
process.lock-ownership-enumerate-producers	Before trusting any "single owner / no double release / no cross-release" claim, grep the whole host project for every writer of that channel message (or acquirer of that lock) — the background scheduler/worker is the usual missing producer.	2026-07-21	link
process.one-worktree-one-committing-agent	Never run two committing agents concurrently on one worktree — give each parallel slice its own worktree branched off the feature branch and merge back.	2026-07-21	link
process.parallel-session-claim	Apply the in-progress label before starting an issue, and still read its dependency notes before touching shared surfaces — a claim prevents duplicate pickup, not overlapping code changes.	2026-07-21	link
process.per-agent-model-routing	State the model tier (and effort, where the client exposes it) in the dispatch itself for every delegated agent — bounded recon → cheapest fast tier at low; mechanical slice against a documented contract → mid tier; judgment-heavy work → orchestrator tier; independent review → a different model family than the implementer.	2026-07-25	link
process.pr-routine-sequence	Worktree off origin/main → implement → regenerate API artifacts → full local tests + cold review + live-E2E ALL before the push → push, open PR, arm the CI monitor at open → fixes after the push are follow-up commits, never amend/force-push.	2026-07-21	link
process.review-disagreement-frontier-judge	When independent reviews disagree on a gate PR, escalate to the frontier judge, and put the proposed fix approach in front of it — not just the disputed finding.	2026-07-21	link
process.shared-tree-readonly	Never commit in /Users/timothy/ersatztv and never read its git log/git status/HEAD to infer anything about main — work in a worktree off origin/main, which is the only source of truth.	2026-07-21	link
process.subagent-drop-resume	Treat a subagent connection drop as laptop sleep or transient network and re-resume via SendMessage — the work survives.	2026-07-21	link
release.api-contract-ci-gate	A PR touching ErsatzTV/Controllers/Api/** or ErsatzTV.Core/Api/** must ship regenerated OpenAPI artifacts (v1.json, v1.d.ts, endpoint-index.md) in the same diff, enforced by a blocking api-docs CI job that regenerates-and-diffs against a fresh build.	2026-07-12	link
release.done-when-merge-consent	A PR may merge only when its linked issue's ## Done-when checklist is fully ticked and the PR's CI is green, enforced by a PreToolUse hook on the Gitea merge tool (deny/allow/ask) plus a pre-push backstop for direct pushes to main.	2026-07-12	link
release.format-as-you-touch-rebase	A blocking format CI job runs dotnet format --verify-no-changes scoped only to the PR's changed .cs files (never the legacy BOM backlog), and a PR branch must be kept current by rebasing on origin/main (never merging main in), enforced by .husky/pre-push → prepush-rebase-check.sh.	2026-07-12	link
release.live-e2e-required	A PR that changes an API write-path handler must include a live-E2E pass (driving the real endpoint/screen and confirming the round-trip through a subsequent read), not only unit/characterization tests, and must state whether live-E2E ran or wasn't required.	2026-07-12	link
release.merge-consent-autogrant	When Done-when boxes are ticked, CI is green, and a fresh positive Review-verdict references head, the merge-consent hook emits permissionDecision: allow to actually suppress the redundant mechanical prompt — the derived state IS the consent, no separate conversational confirmation on that path.	2026-07-12	link
release.migration-rehearsal-prodcopy	Before promoting a migration-bearing release, rehearse the new image's migrations against a throwaway copy of the latest prod backup (scripts/migration-smoke.sh), gating PASS on the migrator's completion log line rather than HTTP readiness alone.	2026-07-12	link
release.prepush-clean-worktree-guard	A fail-open pre-push hook blocks a push when any file in the branch's diff vs origin/main also has uncommitted working-tree or index changes, since a stale-index commit (e.g. git reset --soft + git add over an edited-but-unstaged fix) can silently push, CI-test, and get reviewed a different tree than the one on disk. Scope is precise to pushed-diff files; escape hatch ETV_ALLOW_DIRTY_PUSH=1.	2026-07-17	link
release.promotion-floating-prod	Prod tracks the floating :prod image reference; a tag build's immutable :<version> image is scanned first, then promotion happens via a separate manual DeployStack, with daily auto-update only as a fallback — tag with enough runway before 03:00 to avoid an unscanned promotion.	2026-07-13	link
release.review-verdict-gate	A PR may not merge until a Review-verdict: <MERGEABLE|APPROVED|BLOCKED|NOT-MERGEABLE> @ <head-sha> comment references the PR's current head sha (short-sha prefix match against the verdict's OWN @ <sha> field, marker at COLUMN 0 (no indent, so indented code blocks cannot self-approve), whole-word verdict token, fenced code blocks stripped with markdown fence-length semantics, negative wins over positive on the same head); folds into the H6 merge-consent hook as condition (c). The grammar lives in ONE tested place, scripts/check-review-verdict.sh — #629 found three false-opens that survived because it was implemented inline and untested while this record described stricter behaviour than the code had.	2026-07-12	link
release.verdict-status-check	The H10 review verdict is written as a review-verdict/h10 Gitea commit status on the exact reviewed sha by scripts/post-review-verdict.sh, and that context is a REQUIRED status check on main. Because a status belongs to one sha, a later commit cannot inherit it, so Gitea's own merge_when_checks_succeed refuses to merge a head no one reviewed. The PreToolUse hook additionally refuses to SCHEDULE an auto-merge unless that status is already green on head. A pull_request workflow auto-passes the two exempt classes (Renovate-authored, docs-only) unless the PR touches a protected path (.claude/, .gitea/, .husky/, scripts/, docker/ci/). This extends — does not supersede — release.review-verdict-gate (#303 H10), whose comment convention remains the human-readable artifact and the hook's condition (c).	2026-07-25	link
rulebuilder.relative-date-macros	The visual rule builder's inLast/notInLast date operators compile to/parse from the pre-existing CustomMultiFieldQueryParser macros released_inthelast/released_notinthelast and added_inthelast/added_notinthelast, value form "<n> day|week|month|year"; there is no backend change.	2026-07-23	link
scan.collections-scan-status	GET /api/v1/media-sources/collections-scan-status reports a family-global (not per-source), boolean-only active-scan set read from IEntityLocker; the SPA reconciles authoritatively against it (with a grace-tick helper) instead of a fixed client-side timeout.	2026-07-12	link
scan.getoraddfolder-db-lookup	ILibraryRepository.GetOrAddFolder resolves the existing folder via a DB query on (LibraryPathId, Path), not the caller's LibraryPath.LibraryFolders in-memory navigation, since that navigation is only eager-loaded on the local scan path and is null on remote (Jellyfin) callers.	2026-07-20	link
scan.jellyfin-mixed-content-library	A Jellyfin library whose collection type is mixed (or absent) maps to one ErsatzTV library of LibraryMediaKind.Mixed, scanned by running the movie/television/music-video scanners in sequence against that single library — a library is a place, not a media kind.	2026-07-20	link
scan.libraryfolder-unique-identity	LibraryFolder uniqueness per (LibraryPathId, Path) is enforced by a database unique index over a SHA-256 PathHash (Path is unbounded and not portably indexable), and LibraryRepository.GetOrAddFolder/SetEtag tolerate the constraint violation by re-reading and adopting the winner's row.	2026-07-25	link
scan.musicvideo-server-identity	Jellyfin music videos carry a per-library server identity (JellyfinMusicVideo : MusicVideo with ItemId/Etag, TPT table + ItemId index), so JellyfinMusicVideoLibraryScanner folds onto a shared MediaServerMusicVideoLibraryScanner base that diffs the server item id and soft-trashes (FlagFileNotFound) instead of diffing local paths and hard-deleting. Rows predating the identity are adopted in place — the identity row is inserted against the same MediaItem id, scoped to the scanned library's own LibraryPath — never deleted and re-added.	2026-07-25	link
scan.projection-failure-sweep-guard	MediaServerReconciliationGuard takes a per-enumeration projection-failure count and refuses the file-not-found sweep (logged loudly) whenever it is non-zero against a non-empty existing set — at all six sweeps, including the nested per-show season and per-season episode ones #477 left unguarded (via ShouldFlagMissingDescendants, which applies the failure refusal but not #477's empty-fetch branch). Deliberate guard-clause skips (STRM, virtual, unsupported type) are explicitly not failures and never suppress a sweep. The missing-fraction / ratio threshold floated by #477 is rejected, not deferred.	2026-07-25	link
scan.zero-item-fetch-guard	A media-server library sweep refuses to flag missing items when a successful fetch returns zero incoming items against a non-empty existing set (MediaServerReconciliationGuard.ShouldFlagMissing), rather than treating an ambiguous empty result as a full-library deletion.	2026-07-19	link
sched.auto-tune-foundation	Auto-tune preview enumeration uses EF distinct+count queries for exact counts, while each created channel is persisted as a live SmartCollection; coexistence with existing channels/numbers is additive-only, never mutating.	2026-07-16	link
sched.autotune-detailpanel-members	The Auto-Tune DetailPanel's per-channel content-source list is a live ISearchIndex.Search roll-up through the server-owned AutoTuneAxisMap.GenerateQuery, not an EF distinct+count query, so the preview matches exactly what the built channel's SmartCollection will contain.	2026-07-17	link
sched.autotune-per-channel-overrides	Auto-Tune per-channel overrides reuse the Channel Builder's advanced-options DTO verbatim; per-source weights and bug-colour logo are deferred to #425.	2026-07-17	link
sched.autotune-per-source-weights	Auto-Tune per-source rotation weights and query corrections are supplied at bulk-create time via #70's MultiCollection/SmartCollection machinery, not a post-hoc PUT.	2026-07-18	link
sched.clock-padding-existing	Clock-boundary padding already exists via FillerPreset's FillerMode.Pad (Classic) and pad_to_next/pad_until (Sequential/YAML); #77 is closed as verified+documented, not built new, with a one-click per-channel toggle deferred behind the #388 design-system epic.	2026-07-17	link
sched.clock-padding-schedule-toggle	A ProgramSchedule.PadToNearestMinute (nullable int; null = off) makes the Classic builder pad every content item up to the next N-minute clock boundary without a hand-wired Pad FillerPreset, by reusing the existing per-content-item Pad path in PlayoutModeSchedulerBase.AddFiller. It extends — does not supersede — sched.clock-padding-existing (#77/#388).	2026-07-22	link
sched.playbackorder-support-matrix	Every build-time dispatch site logs a loud (non-fatal) warning on an unsupported PlaybackOrder, and a declared PlaybackOrderSupport matrix + partition tripwire test makes adding a new order safe by construction.	2026-07-18	link
sched.reshuffle-scoped-reset	POST /api/v1/playouts/{id}/reshuffle runs ErasePlayoutHistory (reseeds Playout.Seed + clears anchors/rerun-history) then enqueues a scoped Reset build, so reshuffle always reseeds — even for the non-Classic kinds Reset alone wouldn't reseed; Playout.Seed is surfaced on list/detail DTOs as visible confirmation.	2026-07-16	link
sched.seasonal-scheduling-existing	Seasonal/date-conditional scheduling already ships first-class via IAlternateScheduleItem (Classic ProgramScheduleAlternate, Block PlayoutTemplate) evaluated by AlternateScheduleSelector.GetScheduleForDate (first match in Index order, catch-all last); #73 is closed as already-implemented with a docs-only "seasonal/holiday" recipe added, not new code.	2026-07-17	link
sched.shuffle-source-builder	Shuffle-source construction moves to a static, DI-free ShuffleSourceBuilder (a shared seam, not a service) so Classic and Playlist stop cross-engine reaching into PlayoutBuilder statics; a unified Classic+Playlist enumerator factory is explicitly rejected as a god-factory. Block/Scripted/YAML duplication is left alone, deferred to a follow-up gated on #381.	2026-07-17	link
sched.weighted-shuffle	Fair-share/weighted airtime distribution ships as one new PlaybackOrder.WeightedShuffle = 9 order (equal weights = fair-share), not a retrofit of ShuffleInOrder (which only anti-clumps, since its padding spacers emit nothing) and not a separate orthogonal "distribution" setting; weights live on MultiCollectionItem/MultiCollectionSmartItem (DB default 1, dual-provider migration), bounded at write (1..1000) and clamped again in the enumerator, and the write path rejects WeightedShuffle at every dispatch site that doesn't handle it rather than let it silently degrade to unweighted random.	2026-07-17	link
sched.weightedshuffle-editor	WeightedShuffle per-source weights are edited on the multi-collection editor (property of the MultiCollection), while the WeightedShuffle order itself is offered only on classic MultiCollection schedule items; fair-share is a "reset weights to 1" action, not a stored mode.	2026-07-19	link
scheduling.ondemand-guide-refresh-on-thaw	When PlayoutTimeShifter.TimeShift slides an on-demand playout's materialized timeline forward on tune-in, it reports the channel numbers whose cached guide is now stale — the shifted channel plus any channels that mirror it — and TimeShiftOnDemandPlayoutHandler enqueues a RefreshChannelData for each, so every affected cached XMLTV fragment is regenerated from the just-shifted PlayoutItem rows. The guide and playback both read the same stored PlayoutItem.Start/Finish, but the guide is served from a cached projection — rewriting the rows without rebuilding the cache would leave the guide advertising a stale timeline.	2026-07-21	link
security.artwork-content-type-sniff	Artwork content type is always derived from the stored bytes (never the client-declared value or a ?contentType= query param) at both upload and serve, clamped to an image allow-list, closing the unauthenticated stored-XSS chain; Kestrel MaxRequestBodySize bounds upload DoS.	2026-07-12	link
security.baseline-response-headers	SecurityHeadersMiddleware, registered first in the pipeline, sets X-Content-Type-Options: nosniff, X-Frame-Options: DENY, and Referrer-Policy: strict-origin-when-cross-origin on every response (CSP/HSTS deliberately deferred); API-key comparison is constant-time and playout pagination is clamped.	2026-07-11	link
security.blazor-removal-auth-posture	Removing the Blazor UI's OIDC-challenged surface exposes nothing a user couldn't already reach via the already-open /app SPA (open since phase (a)); real SPA/API authentication is deliberately deferred to #197, and the removal PR must preserve ConditionalIptvAuthorizeFilter, ApiKeyAuthorizationFilter, and JwtHelper access_token support.	2026-07-11	link
security.contract-freeze-honesty	The OpenAPI doc's declared security/401 scheme is generated from the same ApiKeyAuthorizationFilter.EndpointRequiresKey predicate the runtime enforces (so declared auth can't drift from enforced auth), every /api/* action returns a ResponseModel (no raw Application VMs), and Channel REST resources are keyed by immutable Id, never mutable Number.	2026-07-12	link
security.corp-same-origin	SecurityHeadersMiddleware sends Cross-Origin-Resource-Policy: same-origin on every response including /docs//openapi, blocking cross-origin no-cors embedding without affecting allowed CORS-mode fetches or server-side Jellyfin /iptv/* requests.	2026-07-13	link
security.csp-permissions-policy	SecurityHeadersMiddleware sends an enforcing (not report-only) Content-Security-Policy (no unsafe-inline/unsafe-eval; the one inline theme-bootstrap script allow-listed by hash) and a deny-all Permissions-Policy on the SPA//api//artwork//iptv; /docs and /openapi keep only the baseline headers, excluded from CSP because Scalar needs inline bootstrap.	2026-07-12	link
security.fail-closed-api-auth	Every mutating /api request requires X-Api-Key (no open mode); reads are gated by Api:RequireKeyForReads (default true) OR [RequiresApiKey] on sensitive controllers; CORS is an exact-origin allowlist (ApiCors); ForwardedHeaders trust stays configurable but defaults to trust-all-with-warning.	2026-07-12	link
security.iptv-access-token-transport	The /iptv ?access_token= value is percent-encoded (Uri.EscapeDataString) everywhere it is interpolated into an M3U/HLS/XMLTV URL (XMLTV additionally XML-escapes the encoded value), so a structural character can't malform the manifest or guide; Serilog logs a scrubbed request path (access_token → *** via IncludeQueryInRequestPath = false + a RequestPathScrubbed enricher), so a 5xx/Debug /iptv request never writes the token; and every dynamic token-bearing /iptv manifest (channels.m3u, xmltv.xml, the HLS multi-variant/media playlists) returns Cache-Control: private, no-store.	2026-07-23	link
security.iptv-browser-token	Under a JWT-enabled deployment (JWT:IssuerSigningKey set), the browser SPA obtains a short-lived, globally-scoped /iptv/* access token from an authenticated GET /api/v1/auth/iptv-token and appends it as ?access_token=; the endpoint answers 204 when JWT is disabled (nothing to mint). Lifetime defaults to 60 min, configurable via JWT:BrowserTokenLifetimeMinutes.	2026-07-22	link
security.session-auth-dual-credential	ApiAuthorizationFilter accepts a request when a valid X-Api-Key matches OR the principal is an authenticated session (cookie ctv-session, HttpOnly/SameSite=Lax); session-authenticated mutations require the presence-only X-CSRF header or are rejected 403. This narrows the OIDC-inert sub-claim of security.blazor-removal-auth-posture (#206) — the rest of that record's auth-surface enumeration still holds.	2026-07-12	link
security.session-cutover-postify	The browser SPA authenticates cookie-only (no more X-Api-Key from web/); the machine key is repurposed to external/MCP-only via GET /api/auth/machine-key; every side-effecting GET/HEAD under /api is converted to POST so the existing CSRF gate covers it (standing rule: never add a side-effecting GET/HEAD under /api).	2026-07-12	link
session.shared-checkout-refresh	Session end runs scripts/refresh-shared-checkout.sh, which fast-forwards /Users/timothy/ersatztv to origin/main (and reinstalls web/node_modules when the lockfile moved), refusing to touch anything unless that tree is on a clean, non-ahead main.	2026-07-21	link
spa.add-to-layer	All add-to-collection/playlist/schedule affordances share one component layer at web/src/media/addTo/; multi-select is an explicit screen-level toggle, and the per-card menu offers schedule only for the server-validated kinds.	2026-07-10	link
spa.app-shell-extraction	App.tsx is only the composition root over web/src/app/routes.tsx (stable route-object identity), app/AppShell.tsx (shell chrome), and app/ScreenContent.tsx (exhaustive screen dispatch); primary actions are one explicit PrimaryActionProvider registration per screen, replacing the old global ctv:primary-action window event.	2026-07-15	link
spa.autotune-detailpanel-slideover	The Auto-Tune DetailPanel SPA is a reusable SlideOver primitive sharing useOverlayBehavior with Dialog, plus a shared advanced-options model extracted from ChannelBuilder; decorative panes without backend support are dropped.	2026-07-18	link
spa.channel-editor-create-logo	Bare-channel create is a "New blank channel" action on the channels list (reusing Blazor's add-mode defaults) that navigates into the full editor, and an external logo URL always wins over an uploaded logo, matching ChannelEditViewModel precedence.	2026-07-11	link
spa.channel-renumber-prompt	Channel renumbering uses a sequential prompt()-driven "Renumber" action instead of drag-to-reorder.	2026-07-09	link
spa.channels-screen-extraction	The Channels domain is a single-file zero-prop screen (web/src/screens/ChannelsScreen.tsx) with a colocated test file and no sibling helper directory, since its pure logic is too small (~30 lines) to justify a separate business-rule layer like Schedules' itemRules.ts.	2026-07-11	link
spa.collection-custom-order-ui	Collection custom ordering uses per-row Move up/Move down buttons (not drag) and is offered for any manual collection with custom order enabled, not just movies-only.	2026-07-09	link
spa.datetime-local-input	The channel-mode date/time input uses a native <input type="datetime-local"> instead of free-text Chronic natural-language parsing.	2026-07-09	link
spa.deco-templates-table	The deco-templates editor also renders its day/deco assignment as a table, extending (not replacing) the templates-editor-table convention.	2026-07-09	link
spa.download-sample-gate	The SPA disables both Download Media Sample and Download Results while a troubleshooting session is starting/running (Blazor only gated Download Results).	2026-07-09	link
spa.legacy-redirect-matcher	LegacyUiRedirects.TryGetRedirect is a two-tier matcher — an exact OrdinalIgnoreCase Map (Tier 1) then an ordered segment-template pattern list (Tier 2, first-match-wins) — collision-free by construction, with a guard invariant that no rule may prefix-match /api, /artwork, /docs, /openapi, /iptv, /app, or /media/sources.	2026-07-11	link
spa.logs-page-size-local	The Logs page rows-per-page preference is stored in window.localStorage (ctv-logs-page-size), not a server ConfigElement.	2026-07-11	link
spa.playback-troubleshoot-poll	The playback-troubleshooting screen reports FFmpeg completion by polling GET /api/troubleshoot/playback/status (~2s) rather than a server push channel.	2026-07-09	link
spa.playout-reset-button	The SPA keeps a single Reset action (server picks the default build mode) and drops Blazor's separate "Schedule reset" button since its capability already exists via the playout's Edit-details flow.	2026-07-09	link
spa.playouts-screen-extraction	The Playouts domain (including its unguarded PlayoutsRouteScreen route wrapper with local pathname/popstate state) moved as one unit into web/src/screens/PlayoutsScreen.tsx, keeping its screen-specific sub-path route ownership colocated with the base screen; a pure structural move with no API/route/CSS/behavior change.	2026-07-14	link
spa.rulebuilder-nesting	The visual rule builder's Group nests recursively to a single shared cap, MAX_GROUP_DEPTH (types.ts, currently 5, root group = depth 0) — read by the UI's "Add group" gate, parse.ts and the round-trip property-test generator alike; everything else about the builder is unchanged from #176 (compile-only closed Lucene subset over the stored query string, no stored rule AST, field vocabulary from GET /api/v1/search/fields).	2026-07-25	link
spa.schedules-editor-draft-save	The schedules SPA editor mutates a local draft and flushes one explicit Save (PUT /api/schedules/{id}/items) instead of instant-persisting each action; Copy deep-copies all source references (fixing a Blazor omission); the shuffled-schedule GET's EnforceProperties lossy normalization is preserved and mirrored in the SPA's option lists.	2026-07-11	link
spa.sidebar-collapsible-accordions	The shell sidebar's collapse + nav-group-accordion state persists under two hyphenated ctv-sidebar-* localStorage keys (matching the repo's ctv- convention, not the prototype's dotted names); labeled groups default-collapsed.	2026-07-18	link
spa.spa-rebuild-decision	The UI is a full React SPA (ChicoryTV) rebuild over the REST API, not a Blazor Server reskin.	2026-06	link
spa.templates-editor-table	The SPA templates editor renders day/block assignment as a table, not Blazor's drag-and-drop calendar grid — an accepted, deliberate parity deviation.	2026-07	link
spa.topbar-primary-action	The TopBar's primary-action "+" button renders only when the active route declares a non-empty primaryAction, is wired (via a shared usePrimaryAction hook) only on single-unambiguous-create-flow list screens, and is dropped everywhere else rather than left as a dead/no-op button.	2026-07-12	link
spa.yaml-validator-textarea	The YAML playout validator takes pasted YAML via a <textarea>, not a server-side file path, since the SPA has no filesystem access.	2026-07-09	link
startup.parallel-orientation	A fresh session runs two concurrent tracks at startup — Orientation (AGENTS.md/CLAUDE.md → docs/README.md task-signal map → the active decisions catalog docs/decisions/README.md) and, only when no issue is named, Selection (scripts/select-queue.sh N, deterministic live-Gitea ranking). A named issue skips Selection entirely. ersatztv#237, the closed pickup tracker this replaces, is reduced to a single archival breadcrumb and MUST NOT be read for live state.	2026-07-21	link
testing.e2e-cleanup-scope-by-pid	An E2E harness or agent may only kill processes whose PIDs it captured at launch — capture the PID; whoever owns the lifecycle releases it from a trap ... EXIT INT TERM. Never pkill -f "dotnet ErsatzTV.dll" (or any pattern that can match a process this run did not start). A foreign listener is reported, not reaped.	2026-07-25	link
testing.e2e-local-fresh-config-dir	Always point scripts/e2e-local.sh at a fresh config dir — leftover channels/schedules/DB rows bleed state between runs and corrupt assertions. (The readiness-probe hang this record was originally written about was fixed in #533; the fresh-dir rule stands on state-bleed grounds alone.)	2026-07-21	link
testing.live-e2e-prepush-timing	Run live-E2E via scripts/e2e-local.sh before pushing a write-path or UI change, and exercise download endpoints with curl, never a browser tab.	2026-07-21	link
testing.playwright-mcp-download-and-recovery	In Playwright-MCP E2E, fetch file-download endpoints with curl — never a browser tab or window.open — and if browser tools stall repeatedly, pkill -f ms-playwright-mcp and drive a fresh session.	2026-07-21	link
testing.scripted-playout-golden-deferred	The PlayoutBuildGoldenTests in-memory golden net covers Sequential (YAML) as of #381. Scripted's end-to-end pipeline is excluded — ScriptedPlayoutBuilder runs a user-authored external program that drives the engine over HTTP loopback, which the in-memory harness can't pin — so that full-pipeline (integration) harness is deferred to #563. But the scheduling behavior those scripts drive lives entirely in the in-process SchedulingEngine (the ScriptedScheduleController is a 1:1 pass-through to it), which IS directly unit/golden-testable; the earlier "Scripted is un-golden-able by construction" framing overstated the constraint by conflating transport with engine. #395 extracts that shared switch to ContentEnumeratorBuilder and adds a direct regression net (ContentEnumeratorBuilderTests) over it.	2026-07-22	link
testing.troubleshoot-path-cannot-test-branding	Verify logo/watermark/bug changes through a real channel playout — a green troubleshoot run proves nothing about branding.	2026-07-21	link
