The code cited its plan instead of saying why: `E28 review J4`, `(R6 S3b)`, `S1 justified…`,
`deep-review round 5`. That plan lives in the private ops repo, so for every reader of this one the
citation was noise, and a sentence whose subject was the plan step ("round 2 showed…") hid its
lesson behind an id. Each one is gone and the "why" kept: a bare citation is deleted, a sentence
carrying a lesson is reworded around it ("a later attempt showed…").
Measured (`scripts/audit_metrics.py`, product code): 652 lines in 270 files carried an epic code by
the definition the next commit holds (507 / 241 by the old, two-digit-only one) -> 0. Across all
code, tests, scripts and configs: ~1100 epic-code lines plus ~320 sprint/round ids.
Behaviour unchanged, checked mechanically: every changed .py file has the same AST once docstrings
are blanked; css/sh/toml/yml/json files are identical once comments are stripped; the only
non-comment changes in TS/JS are test titles, one description string in a contract table, and five
ESLint messages, whose text is all the gates snapshot diff holds. Not touched: Markdown (docs and
the changelog keep their history), Alembic migrations, TV episode notation (`S2 · E5`), DESIGN.md
ids (`C1`, `B4`, `S3h`), tracker ids (`SEC-16`, `DX-17`).
One stale claim fixed on the way: test_hls_reaper's docstring said the player checkpoints "every
10 s whether or not it is playing", which plex/stream.py calls wrong; it now says what the code does.
Helpers flush and handlers commit — but every test request shared the test's session, so a
follow-up GET or an assertion read the flushed write and the suite stayed green over a handler
whose commit was missing (production's get_db closes the session: the write is rolled back behind
a 200). The db fixture now hands out `db.info["request"]`: the same session, recording each request
that ends normally with a flushed, uncommitted write, and failing the test on it at teardown. All
28 get_db overrides use it (a convention test keeps it so); the full suite passes under it, and
dropping the commit from add_item turns a playlist test red.
22 test files set `app.dependency_overrides[...]` by hand and tore down with a blanket `.clear()`
in a `finally`, which wipes every override rather than the test's own and stops fixtures composing.
They now take the `override_dep` fixture (helpers get it passed in), whose teardown restores each
key's prior value; no clear() carried meaning between two phases of a test. A convention test fails
any test file that writes `dependency_overrides` directly.
Deep-review round 2 on the round-1 fixes (all low):
- part_key churn (state): round 1's part-key reset re-probed EVERY sync for a
multi-version item (an original + a Plex 'Optimized' copy), because
_media_facts reads media[0]/part[0] whose order Plex doesn't guarantee stable,
oscillating transcode_hw between the two versions. Gate the part-key signal on
a single-version item (len(Media)<=1); codec-change reset still applies to all.
A multi-version same-codec re-encode not self-healing is an acceptable rare
edge; a per-sync re-probe loop is not.
- dead i18n key: this diff's playableClass() collapses to transcode_hw/sw, so the
bare plex.playable.transcode key it orphaned is now unused (knip can't see
dynamic keys). Dropped from both locales, parity kept.
- test: cross-facet narrowing by an active playable class (a co-facet's year
range collapses to the selected subset) — the flip side of self-exclusion,
previously unpinned.
The aria-label+title double-announcement on the card dot is a deliberate accepted
trade-off (reliable SR name + mouse tooltip). Backend + FE gates green.
Deep-review round 1 on feature/plex-playback-class-filter:
- Sticky watermark (medium): _apply_item reset the bit-depth probe watermark
only on a codec-string change, so a same-codec re-encode (8-bit->10-bit HEVC)
kept a stale video_bit_depth/transcode_hw forever (the backfill only re-probes
media_probed_at IS NULL rows). Also reset when the Plex Part key changes (the
file was replaced), not just the codec.
- i18n parity (medium): the HU playback-class labels were mixed-language (only
'direct' translated). Translated remux/transcode_hw/transcode_sw and the
tooltips consistently to Hungarian (Kozvetlen streameles / Atkodolas).
- Layering (low): _PLAYBACK_CLASSES was module-private yet imported across into
routes.plex.browse; renamed to public PLAYBACK_CLASSES (it is the shared
source of truth for facet order + zero-fill).
- a11y (low): the browse-card playback-class dot conveyed meaning only via a
mouse-hover title; added role=img + aria-label so SR/touch users get the class.
- tests: the NULL/unprobed transcode_hw -> SW fold (filter + facet), facet
self-exclusion under an active playable filter, the migration codec-set ==
HW_DECODABLE_CODECS drift guard, the probe-batch bound + oldest-first order,
the transient probe-failure retry path, and the same-codec re-encode re-probe.
Backend gate green (ruff + full pytest); FE gate green (tsc/lint/knip/prettier/
vitest). NOTE: the facet-vs-runtime disagreement for 10-bit HEVC (C1) is the
known merge-order constraint — this branch's runtime is codec-only; the facet
becomes truthful once BUG1/tonemap's bit-depth-aware routing lands with it. Left
as a sequencing constraint, not code-changed here.
Adds a movie-scoped "Playback" filter to the Plex feed so a user can isolate items by how
they play — the groundwork for collecting HW-transcodable (or no-transcode) versions.
Four classes derived from the stored `playable` + a new `transcode_hw` facet:
- Direct Play (direct), Direct Stream (remux)
- Transcode · HW — playable=transcode AND the iGPU can hardware-transcode it
- Transcode · SW — playable=transcode, software libx264 only
The HW/SW split is precise, not codec-only: a 10-bit/HDR HEVC is HW-decodable yet breaks the
VAAPI nv12 pipeline (the same case plex/stream special-cases), so it must count as SW.
Backend:
- New PlexItem columns (migration 0077): transcode_hw, video_bit_depth, media_probed_at.
Migration backfills transcode_hw codec-only so the filter works immediately.
- `plex.sync.transcode_hw_capable` is the single classifier; the HW-decodable codec set moves
to sync as `HW_DECODABLE_CODECS` and plex.stream imports it, so the catalog facet and the
runtime encoder choice can't disagree by codec.
- Bit-depth backfill (`_probe_media_batch`, wired into sync): probes only HW-decodable transcode
items' video Stream for bit-depth + HDR and refines a 10-bit/HDR HEVC to software. Bounded
per run, watermarked by media_probed_at. A codec change resets the watermark (stale probe).
- Filter + self-excluded facet on a shared `playback_class_expr` CASE (movie-leg only — a show
is an aggregate with no single class). transcode_hw threaded onto the feed/detail/card JSON.
Frontend:
- Multi-select "Playback" Combobox in the sidebar (movie scope, facet-empty drop-out), active
chips, 4-way corner-dot badge (green/blue/amber/red) + tooltip, and an info-page playback chip
with a codec · bit-depth subtitle. New `bg-info` (blue) token, i18n HU/EN parity.
- Fix a regression where the card's playback dot lost its hover tooltip: the full-card reveal
overlay swallowed the cursor; the dot now sits above it (z-20).
Gate: backend full lane + frontend typecheck/lint/knip/prettier/vitest all green. Browser-UAT'd
on localdev (filter narrows to the SW set, facet counts, badge colour + tooltip, info chip).
