CreateChannelFromLineupHandler resolved every advanced override with
advanced.X ?? template.X, so null always meant INHERIT and a channel could
not drop a template-set watermark / filler / preferred language. Add an
optional typed `clear` enum list to CreateChannelFromLineupAdvancedOptions:
omitted/null still inherits (byte-stable for existing clients), a field named
in `clear` is forced to none. Set+clear of the same field is a 422.
The enum (CreateChannelFromLineupClearField) lives in ErsatzTV.Core so the
OpenAPI string-enum scan renders it as a string enum, matching every sibling
advanced-options enum. Handler resolves clearable fields once via
ResolveClearable and validates set/clear conflicts via ValidateClear;
reference validation skips existence checks for cleared (null) refs.
SPA: the shared advancedOptions model re-adds a real "None" option to the five
id selects (watermark + fillers) in both the Channel Builder and the Auto-Tune
DetailPanel, routed through a CLEAR overrides sentinel that applyOverridesToRequest
folds into advanced.clear (never leaking onto the wire as a field value). The
backend enum also covers the preferred audio/subtitle language strings for
machine clients; the SPA text inputs keep "empty = inherit" (tri-state deferred).

Three Low findings from the #536 clamp re-review, unreachable today (one
guarded release site) but filed against the day a second release site is added.
- §1: Release() now reads the count and CAS-decrements only when current > 0,
so it never publishes a negative count even transiently. The prior
decrement-first-then-clamp shape dipped to -1, which a concurrent TryAcquire
could read as phantom room and over-admit at the limit (re-opening the #529
QSV pool exhaustion). It records the unbalanced release synchronously on the
offending thread rather than blaming a later innocent release.
- §3: Release() returns bool; HlsSessionWorker logs a warning on the false
(unbalanced) return — the one in-band signal a future second release site
would need. WorkAheadSlots stays logger-free by design.
- §2: UnbalancedReleases doc-comment corrected — it can under-count (an
over-release while count > 0 cancels a coexisting leak and goes unrecorded);
no false positives, but zero does not prove correctness.
Test: Release_Unbalanced_NeverPublishesNegativeCount (2M unbalanced releases vs
4 count-samplers) with a documented, verified negative control (reverting to
the decrement-first body makes readers observe the transient -1).
Adds a decisions.md entry (ffmpeg.work-ahead-slot-release-never-negative).

Timothy asked why the kickoff handoff doc stores historical narrative when
it should be instructions. It shouldn't — its own lore section is chartered
as "STANDING workflow/orchestration rules only" with the why belonging in
docs/decisions.md. But an inventory of every bullet against the decision
corpus inverted the premise: only ~8 of ~38 were actually covered. 19 had
no record anywhere and 11 more were half-covered, so that single file was
the ONLY copy of the mandatory review rubric, the whole CI-triage
vocabulary, the build-concurrency policy, the H12 session-end audit, and
the plumbing-merge recipe. Pruning first would have destroyed them.
So the records come first. New topic file docs/decisions/workflow-process.md
carries 32 records (ci.*, process.*, testing.*) covering every NONE and
PARTIAL the inventory found, including the Gitea `?milestones=` no-op bug
whose only copy was the archived selector section this prune deletes.
Only then the prune: HARD CONSTRAINTS and the lore section become one- or
two-line rules, each citing the decision key that holds its evidence, and
the 40-line "Archived — do not follow" section is gone. 636 -> 353 lines,
with every cited key verified to resolve against the corpus.
The aggregate corpus budget is re-baselined 4800 -> 5600 with the reason in
the code: the corpus grew because knowledge MOVED into it, which is the
system working, not drift.

A session was handed docs/handoffs/chicorytv-issue-queue.md pasted out of
/Users/timothy/ersatztv while that tree was 81 commits behind, so it still
described the queue protocol #520 retired the day before (read tracker
command was ever run against that tree, so every existing "never read its
HEAD" guard was irrelevant: a stale checkout serves stale FILES, and docs
are what a kickoff depends on. Nothing broke only because selection went
through scripts/select-queue.sh.
The lore bullet on that tree already prescribed the shape of the fix for
its earlier failure modes — "a design flaw, not a discipline failure; a
check does not stay true" — so this removes the stale condition instead of
adding another check.
scripts/refresh-shared-checkout.sh fast-forwards the tree to origin/main
and reinstalls web/node_modules when the lockfile moved. It is deliberately
timid: it refuses and changes nothing when the tree is not on main, is
dirty, is ahead, or is mid-rebase/merge, and it never switches branches,
stashes or discards. A NO-OP is a normal outcome.
Uses npm ci rather than npm install — the first version used install,
which rewrote package-lock.json and left the tree dirty, i.e. the exact
state the next run refuses on, so it would have disabled itself after one
use. Asserts the tree is clean at exit.
refs #541
An on-demand channel (`PlayoutMode.OnDemand`) already is the "resume where I
left off" feature: `Playout.OnDemandCheckpoint` persists the viewer's position
and `PlayoutTimeShifter.TimeShift` slides the materialized timeline forward on
tune-in so the paused item is active again. Because it rewrites `GuideStart`/
`GuideFinish` alongside `Start`/`Finish`, guide and playback freeze together —
structurally avoiding the free-running-wall-clock desync #68 was filed about.
The one gap: `TimeShift` rewrote the stored `PlayoutItem` rows but the XMLTV
guide is served from a cached fragment that only `RefreshChannelData` rebuilds,
and the tune-in path never enqueued it. So an external EPG client polling after
a thaw could see a stale timeline until the next incidental rebuild.
Fix: `IPlayoutTimeShifter.TimeShift` now returns the channel numbers whose cached
guide is stale — the shifted channel plus any channels that mirror it (the same
fan-out `BuildPlayoutHandler` already does) — and `TimeShiftOnDemandPlayoutHandler`
enqueues a `RefreshChannelData` for each on `CancellationToken.None` (post-commit
side effect must not be abandoned if the session token cancels).
Tests: handler enqueues a rebuild per stale channel (+ mirror + no-shift cases);
`PlayoutTimeShifter` reports source+mirrors on a shift, empty on Continuous /
zero-offset / active-unforced, and correctly seeds+shifts a never-watched playout.
Non-vacuity of the enqueue proven by a compiling negative control.
Docs: channels.md (On-demand resume section), domain-model.md, decisions.md
(scheduling.ondemand-guide-refresh-on-thaw). Per-viewer resume is out of scope
(single per-channel checkpoint; #68 says per-channel suffices).

The slot check and its increment straddled an await: `Run` compared
`Volatile.Read(ref _workAheadCount)` against a DB-backed limit, and the
increment happened later inside `Transcode`. Every simultaneous tune-in
therefore observed `0 < limit` and started unthrottled — three concurrent
tunes on prod with a limit of 1 all ran with no `-readrate`. `Interlocked`
on the write side alone buys nothing when the read side is a separate,
earlier load (same class as #231/#250).
Extract the counter into a `WorkAheadSlots` pool whose `TryAcquire(limit)`
claims via compare-exchange, so the count never even transiently exceeds
the limit that the QSV hardware-frame pool sizing (#529) is derived from.
`Run` claims the slot and passes ownership in; `Transcode(bool
ownsWorkAheadSlot, ...)` derives `realtime` from it and releases it in its
existing `finally`, keeping acquire/release one-for-one. Acquisition stays
in the caller because `Run` sets `_state` from the outcome and `Transcode`
reads that state on entry to pick the item start time.
Tests hammer 8 threads x 20k rounds (a single Barrier round does not
collide on this hardware); the documented negative control reinstates the
check-then-act body and produces 15912 over-claiming rounds of 20000.
Also annotates the #350 decision record, whose "every concurrent tune-in
falls back to the throttled path" bullet described the intent rather than
the behaviour.

Exhaustive triage of the closed tracker ersatztv#237, whose 111 comments
server-management#642 excludes from MemPalace ingestion (over the per-file
cap) and #520 removes from startup. #524's premise was that facts living only
in those comments would be orphaned and need curating into lifecycle records.
Result: zero decision-shaped orphans. Every durable decision-shaped fact is
already held by the decision corpus or by the individual issue the comment
narrates -- which the exporter does ingest. The tracker was always the lossy
copy, because the session protocol required the fuller closing record on the
worked issue first.
- docs/decisions.md: new active record docs.tracker-comment-retrofit, leading
with the reusable rule (check the worked issue BEFORE the decision corpus)
and the consequence for #642's benchmark row, which has no valid subject.
- docs/tracker-retrofit-triage-237.md: the audit trail -- method, per-comment
classification of all 111, totals, and the one candidate raised and
disproved (#497's Guids/Directors scope, stated more fully on its own issue).
- docs/handoffs/chicorytv-issue-queue.md: sweeps the two genuinely orphaned
LORE facts the triage surfaced (e2e-local.sh readiness probe hanging on a
reused config dir; troubleshooting playback cannot exercise channel branding).
- docs/README.md: index the new doc.
The claim is deliberately narrow: no *decision-shaped* orphans. The lore bucket
was classified but not coverage-checked, and it was not empty -- hence the sweep.
fixes#524
Cold adversarial review returned BLOCKED on the documentation half. Addressed:
- The new decision record carried no lifecycle metadata block, taking the repo from
82/82 to 83/82 and making it invisible to the by-key catalog lookup that #521
established the same day. Added key/status/since/supersedes/superseded-by
(ffmpeg.qsv-extra-hw-frames-floor) and regenerated docs/decisions/README.md;
decisions_validate.py now reports OK with no legacy-unmigrated notice.
- The entry claimed to correct the #350 record but left that record untouched, so the
stale "the burst is bounded" claim stayed authoritative for anyone resolving
ffmpeg.hls-cold-start-burst. Added a forward-pointing correction note there (hence
the [decisions-edit] token on this commit).
- The floor was applied silently. QsvPipelineBuilder.SetAccelState now logs a warning
naming both the configured and applied value, because raising a deliberately small
pool costs additional surfaces (64 NV12 1080p surfaces is roughly 190 MiB, 760 MiB
at 4K) on memory-constrained iGPUs.
- Narrowed an overstated claim in the entry: 1..63 are untested, not known-bad. We
raise them because the risk is a channel serving nothing, not because asking for
less is illegitimate. Recorded as a deliberate over-reach with a stated cost.
- Corrected a factual error: SubtitleScaleQsvFilter also formats extra_hw_frames but
is dead code with no construction site, so it is NOT covered by the guard.
- Config-vs-behavior mismatch: Create/UpdateFFmpegProfileHandler now normalize on
save so stored rows converge on what the pipeline runs, and the SPA field carries
min=64 rather than defaulting the display to 0. Render-time flooring is kept as the
net that fixes existing deployments with no migration; the remaining gap for
un-resaved rows is recorded as an accepted residual.
- Tests strengthened: pinned to the literal measured 64 rather than to the constant
(so lowering the floor cannot quietly satisfy them), added a negative-value case,
added a deinterlace-upload case, and replaced the narrow ShouldNotContain with a
regex asserting EVERY extra_hw_frames occurrence in the command is >= the minimum.
Negative control re-run against the strengthened tests: reverting the floor fails 5,
with the build verified succeeded first. Full suite green (4086 .NET, 891 web).
Review finding that needed no change: the "single point" claim was independently
verified — no bypass exists, every FFmpegState construction routes through
MaybeQsvExtraHardwareFrames.

Live-E2E of the write path (scripts/e2e-local.sh) confirmed the feature end to
end — good URL -> cached /iptv/logos/<hash>, M3U emits the cached URL, cached logo
serves back as PNG, rejected save leaves the prior logo intact — and caught that a
bad/non-image/oversized logo rejects as 422 (BaseError -> ValidationProblemDetails
via ToErrorResult), not 400. 400 remains model-binding-only. Corrected channels.md,
api-conventions.md, and the graphics.channel-logo-caching decision Rule + catalog.
New lifecycle record graphics.channel-logo-caching (supersedes: none — narrows
for YAML image elements). Regenerated the active catalog. channels.md + api-
conventions.md updated for the new save-time download + 400s.
- Exclude docs/decisions/retrieval-eval.md from active decision parsing
(_NON_DECISION_FILES); its `## N.` eval-question headings were being
miscounted as 7 legacy-unmigrated records.
- Add decisions_lib.metadata_line_count() + a decisions_validate guard
that fails a record with more than one `key:` metadata line, so a
stacked-metadata-block migration bug (which the parser silently
tolerated by reading only the first block) can't recur unnoticed.
TDD: test_duplicate_metadata_block_fails / test_single_metadata_block_passes.
- De-duplicate the 6 docs/decisions.md records left with two stacked
metadata blocks (scan.getoraddfolder-db-lookup #488,
scan.musicvideo-reconciliation #494, scan.jellyfin-mixed-content-library
#489, iptv.logo-drives-bug-preset #67, ffmpeg.qsv-decode-encode-split
#498, ci.small-lane-git-only server-management#639), merging the union
of Signals/paths/issues/Mechanics from both blocks and keeping the
richer Rule wording; rationale prose untouched.
- Fill in the deferred Q6b row in docs/decisions/retrieval-eval.md now
that startup.parallel-orientation is active in docs/decisions.md,
scoring it as a real active-vs-superseded question against the
archived docs.queue-state-gitea-tracker.
- Regenerate docs/decisions/README.md via build_decisions_catalog.py.

Retire the line-level append-only mechanic (ersatztv#303 H9) in favor of the lifecycle validator
built in Tasks 1-5. .claude/hooks/decisions-guard.sh is now a thin fail-open shim around
scripts/decisions_validate.py; .husky/pre-commit calls it for the structural (working-tree) checks,
.husky/commit-msg drops the old staged/[decisions-edit]-deletion block and keeps only the
Co-Authored-By check. The Gitea decisions-guard job is renamed "decisions lifecycle" and now runs
decisions_validate.py --base/--head (structural + body-diff + no-vanish) and
build_decisions_catalog.py --check (active catalog drift), with actions/setup-python@v5 added since
the bare `small` lane doesn't guarantee python3; the old 1800-line consolidation-floor step is
removed (replaced by the validator's aggregate active-corpus budget). docs/decisions.md's header is
rewritten from append-only to lifecycle framing (metadata schema, statuses, generated catalog,
archive, same-PR supersession); [decisions-edit] is re-scoped (not removed) to rationale-prose
edits/factual corrections only. docs/ci-cd.md's release ritual and hook/job descriptions are
rewritten to match.
Also fixes a pre-existing validator false-positive surfaced while sanity-checking against
origin/main: Task 6's #303 H9/H3 split (commit d09be57e) renamed the archived record's heading
away from the pre-split original, which the validator's heading-based relocation check reads as
"removed without an archive copy." Restored the archived heading to match the original text
(functionally unchanged — still status: superseded, same key) and updated the two prose
cross-references (migration-map.md, release-ci-governance.md) that pointed at the old anchor.
PR1 scope only (per brief): does NOT wire the kickoff-guard CI step or touch the
kickoff/README/select-queue docs — that's Task 8/PR2.

The archived docs.append-only-guard record bundled the genuinely-superseded
H9 (decisions.md append-only) with the independent, still-active H3
(root-screenshot pre-commit guard), relocating both into archive/ and
burying an active decision in the history wing. Split into two records:
docs.append-only-guard stays in archive/release-ci-governance.md,
status: superseded, H3 content removed and replaced with a forward
pointer; ci.root-screenshot-guard is a new status: active record in the
active docs/decisions/release-ci-governance.md, with the H3 rationale
paragraph lifted byte-identical from the original bundle. Updated
migration-map.md (new row + a "Migration conventions" note: never
relocate an active decision to archive/) and regenerated

_anchor() mapped each space/hyphen to its own '-' without collapsing runs,
so the standard heading separator " — " (space, em-dash, space) produced a
double hyphen in every generated anchor. Since nearly every real decision
record heading uses that separator, this made the catalog emit a dead link
for essentially every row. Fix: after building the char list, collapse
consecutive '-' into one and strip leading/trailing '-' via re.sub, matching
how Goldmark/GitHub/Gitea sluggers behave.
Also fixed main() writing an extra trailing newline (want already ends in
"\n", then "+ \n" appended a second one) so docs/decisions/README.md now
ends with exactly one trailing newline; --check still compares via .strip().
Added test_anchor_collapses_em_dash_and_keeps_underscore to pin the anchor
behavior against the reported iptv.base_url case.

as a compact table of only 'active' decision records (sorted by key), and its

Two concurrent adds of the same item both membership-check it absent, both
insert the CollectionItem composite key, and the loser's
SaveChangesForcingVersion threw an uncaught DbUpdateException (SQLite 19 /
MySQL 1062) -> 500. Now the loser is an idempotent no-op.
- ConcurrencyExtensions.TrySaveChangesForcingVersion: bool-returning sibling
that catches only a classified unique/PK violation and returns false.
- 10 single-item Add*ToCollection handlers: return Unit.Default (no-op, skip
fan-out) on false — the racing winner already inserted + rotated + rebuilt.
- Bulk AddItemsToCollection: retry on a fresh context against recomputed
membership so a partial-overlap collision doesn't drop the non-colliding
items (bounded loop; common no-collision path runs once).
- Provider detection via a TvContext.IsUniqueConstraintViolation static
delegate (matches the existing IsSqlite/LastInsertedRowId provider seam),
wired from Startup to SqliteErrorClassifier / MySqlErrorClassifier.
- Add*ToPlaylist is NOT affected (PlaylistItem has its own identity PK; a
playlist may legitimately contain the same item more than once).
Tests: a negative-control anchor proves the race genuinely throws a classified
exception; end-to-end handler tests reproduce a real cross-connection race via
a shared-cache SQLite harness + a SavingChanges interceptor (the single-conn
in-memory fixture cannot). Every fix-dependent test verified to fail with the
catch disabled.
