`handling` is the one required key: a file without a valid one is not a channel. The smallest channel is `{ "handling": "youtube", "url": "https://www.youtube.com/@example" }`.
-Every other key is optional and has NO default of its own: an absent key means whatever its description says — for the per-channel overrides, inherit the global setting of the same name; for `name`, `url`, `dataDir`, `subLangs` and the sync-state stamps, simply unset. So an ill-typed or out-of-range value is not coerced — it is DROPPED, as if the file did not spell it. Unknown keys (including the retired `excludeFromSync`, now a paused `sync` tier in the channel-priority document) are dropped by every read and every write.

The two exceptions write a whole config, and only when there is no readable file to patch: a media move and a channel rename record `dataDir` from their own copy of the config.

+// THE MEDIA TIER ON DISK — the hook that moves a finished media file out of
+// `data/<id>/` and leaves a link behind, and the one way to remove one.
+//
+// The layout (plans/release-17.md, "The model (A′)"):
+//
+// channels/<slug>/data/<id>/audio.mp3 -> ../../media/<id>/audio.mp3 (a RELATIVE link)
+// channels/<slug>/media a real directory on the corpus disk (tiered in place),
+// or ONE absolute symlink to <root>/<slug>/media (relocated),
+// or absent (classic: the media is real files in data/<id>/)
+//
+// Readers never change: they open `data/<id>/<name>` and the kernel follows the
+// link. Writers change in exactly two ways, and both are here:
+//
+// - EVERY SITE THAT FINALISES A MEDIA FILE calls the hook (`tierMediaFile`,
+// `tierVideoDir`, `tierChannelMedia`) once it has renamed its temp into
+// place. yt-dlp's postprocessor and this app's transcode both `rename()` a
+// temp OVER the final name, which replaces a link with a real file — the
+// hook then moves that file into the tier, over the stale copy there.
+// - EVERY SITE THAT DELETES ONE calls `removeMediaFile` / `removeVideoDirMedia`.
+// A plain `rm` of `data/<id>/audio.mp3` removes the LINK and orphans the
+// bytes on the media drive, which no sweep would ever find again.
+//
+// THE HOOK NEVER THROWS INTO A DOWNLOAD. A classic channel (no `media/`), a
+// relocated one whose drive is unmounted (the link dangles), a stalled drive,
+// a full disk: the file stays a real file in `data/<id>/`, readers are
+// unaffected, and the next sweep that calls the hook tiers it.
+//

- **umtool's report videos keep every clip's sound on its picture.** In a crossfaded cut each clip's audio was placed by the audio's own length and its picture by the picture's, and an encoded clip's audio is routinely a few to twenty milliseconds shorter or longer than its video, so the sound drifted further ahead clip by clip: by the end of a seventeen-clip cut it was a third of a second early, and two seconds on one with title and sources cards. Each clip's sound is now padded or trimmed to exactly its picture's length before the crossfade. Every crossfaded report video changes when it is rebuilt, and is in sync; a hard-cut video was not affected.
- **umtool's report videos can wear an on-screen deck: one panel under the footage for the whole cut, with a pip timeline, a title per clip, its source and date, and its QR.** A report manifest whose `render` says `"chrome": { "engine": "hyperframes", "layout": "deck" }` scales the footage into a box above a 190 px panel (both sizes are settings) and draws, over the whole cut, one unlabelled pip per clip on a track that fills as the cut plays, the clip's own title from `onscreen.title`, a subtitle naming the recording and its date (the channel too when the cut spans more than one; `onscreen.subtitle` replaces it), and the clip's QR. At each clip change the marker travels to the next pip and the title, subtitle and QR hand over; over a card the panel slides away and comes back after. The citation header, the corner QR and the section footer are not drawn on such a cut, and chapters take the clip's on-screen title. Every setting (sizes, spacing, date format, what the subtitle names, whether cards keep the panel, the motion's timings) is in `render.chrome.deck` and checked when it is saved; an unknown or out-of-range one is refused with a sentence saying why. The panel is rendered once per cut by HyperFrames (pinned to 0.8.24; `HYPERFRAMES_PKG` or `HYPERFRAMES_BIN` override it) and reused until its text or settings change. `build-video.mjs --chrome-only` redraws it over the built segments without rebuilding or fetching anything, `--no-chrome` builds the framed cut without it, and `--chrome-preview <at> <dur>` renders a short window. In umtool, the report page has an **On-screen** section — a switch, the settings, a table of every entry's title and subtitle with the automatic subtitle as its placeholder and a character counter, a live preview with a scrubber, a true still, **Re-render on-screen** and the built video — and the clip bench has on-screen title and subtitle fields with the panel previewed over the clip. The deck changes nothing, byte for byte, in a cut whose manifest has no `render.chrome`.
- **A report cut that wears the on-screen deck can show posts — Bluesky or X statements — as cards over the footage.** A report manifest's `posts` list (each with its platform, handle, date, words and link) is drawn near the end of the clip each post belongs with: the clip whose recording most closely precedes it by date, unless the post names one with `attachTo`; `hide` leaves one out. A clip's posts appear four seconds apart and stack down a column at the frame's top right; as the first appears, the footage eases aside (to 86 % of its box, at the far side) to make room, and the clip's last frame is held, in silence, for 2.5 seconds so the last post can be read; then they all leave together in the change to the next clip, which comes in at the normal size. When the column is full the oldest slide up and out. Each card slides in from the edge of the frame and flares in the deck's accent as it lands; it has an accent rail down its edge and shows the post's date, a platform label ("Bluesky" or "X") beside `@handle`, its words in paragraphs up to seven lines with an ellipsis, and a QR of the post's link, in the deck's colours and faces. The hold and the move are made where the cut is joined, not in a clip, so `--chrome-only` changes them without rebuilding one; chapters and the deck's timing count the hold. The timing, the hold (`hold`, 0 turns it off), the move (`shift`: its scale and seconds, or `false`), the column's side, width and inset, the QR size and the line limit are settings under `render.chrome.deck.posts`, and a bad post or setting is refused with a sentence before a build fetches anything. Only the seconds the cards are up are rendered, one short sequence per clip, cached like the deck; `--chrome-only`, `--chrome-preview` and a hard-cut cut lay them as they lay the deck, and `--no-chrome` draws neither — though it still holds and moves the footage, which are part of the cut rather than the chrome. A first post that appears inside the hold still moves the footage, and a hold is a whole number of frames. `posts` changes nothing in a cut that has none, and without the deck it is not drawn at all.
+- **A report cut's posts can be a feed: a column beside the footage for the whole cut, each post ticking in as its clip starts, with no pause.** `render.chrome.deck.posts.layout: "feed"` (the default, `"popup"`, is the cards described above) puts every post in one column on the right, standing on the deck so the two read as one L-shaped panel around the picture. The footage of every clip and still is framed, for the whole cut, into the box left beside the column (1272×716 at 1920×1080 with the default 600 px column, against 1574×886 under the deck alone); nothing moves and nothing is held, so the cut is as long as its clips. Before the first post the column shows its header — the platform and the handle, or "Posts" when there are several authors — and an empty state. Each post ticks in at the start of the clip it belongs with, a crossfade's length in (just after the crossfade into it, and as far into the first clip, which has none), a clip's next ones `posts.seconds` apart (closer on a short clip): it lands at the top with an accent flare and keeps a lit rail while it is the newest, and the posts already up slide down to make room; when the column is full the oldest fade out at the bottom. Each card shows the post's date, its words up to `maxLines`, and its QR. Over a card or the teaser the column slides out of the frame with the deck and comes back after. The column is drawn by one composition for the whole cut, cached like the deck's. Switching the layout reframes every segment, so it takes a normal build (with `--skip-fetch` it re-cuts from the cached windows); `--chrome-only` over segments framed for the other layout is refused with a sentence naming them, because each segment's `<id>.cut.json` now records the box it was framed into. In umtool, the posts settings have a **layout** switch, and the live preview shows the column for the whole scrub with the footage in its box. A cut in the popup layout, or without posts, builds exactly as before.
- **A report clip can go silent partway through, a report cut can fade out at its end, and the deck's QR names its site in larger type.** A clip's `muteFrom` (in the recording's own seconds, inside the clip) silences it from that second to its end while the picture plays on, after a 40 ms fade that ends there, so nothing clicks and no next word leaks in; a hold on that clip stays silent. `render.endFade` (seconds; 0, the default, is off) fades the cut's last segment, whatever it is — a clip with its hold, a closing card or a teaser — to the background colour and to silence over its final seconds, all of it when the segment is shorter, and the deck stays drawn over it. Both are applied where the cut is joined, so `--chrome-only` changes them without rebuilding a clip, and a value out of range is refused with a sentence before a build fetches anything. Each clip build now writes `<id>.cut.json` beside its segment, saying where in the recording the segment really starts after its cut was snapped to a silence; `muteFrom` is measured from it, and a segment built before this measures from the clip's unsnapped start and says so. The site's name beside the deck's QR is now exactly as long as the code is tall, for any site. Neither key changes a cut that does not set it.
- **umtool's clip bench stops exactly where a range ends, and sets a clip's mute mark.** The bench's **play selection**, the edge auditions, the auto-audition and a click on a transcript line now play the window's sound through the browser's Web Audio, from a decode made on the server by ffmpeg — the same timeline the build cuts on — and each stops on the audio clock where its range ends, at every speed. They used to play on the video element and were stopped when it next reported its time, which overran the end by up to a quarter of a second, by a different amount each time. The picture follows, muted. If the sound cannot be decoded, the video element plays as before and the bench says the playback is approximate and why. The mute mark sets the clip's `muteFrom`: `m` puts it at the playhead, **pick on waveform** puts it where you click, `;` and `'` nudge it (with shift, by half a second), and `M` or **clear mute** removes it. It is saved with the window like the edges, every playback goes silent at it with the build's own 40 ms fade, and a window save that would leave it outside the clip is refused unless the same save moves or clears it — or, when it is within 0.02 s of the new edge, moves it onto that edge. The decoded sound is served by a new `GET /api/report/audio`, at most 120 seconds of a cached window at a time, as WAV.
-- **A report cut can end on a teaser card: a few lines popping in over a dark cinematic ground, with a trailer hit under each.** A report manifest's `teaser` entry (`lines`, `seconds`, an optional `tail`) is a full-frame card drawn from its own words, one to five lines each popping in top to bottom with a scale overshoot, a blur that sharpens, and a flash of the accent; with three or more lines the first is a small overline, the last a mid-size date, and the ones between a big title. A line written as `{ "text": …, "break": … }` draws its ending as a smaller second tier a beat later, and the tail fades in after the last line on its own. Under each pop is a synthesised boom, the title's the biggest, and under the tail a low swell; `"hits": false` makes the card silent. Put after the last clip, it joins with the ordinary crossfade and takes the cut's end fade. A line too long to fit the frame at its smallest size is refused with a sentence saying how many characters fit (a title holds 34). It is rendered once and re-rendered when its words change, `--chrome-only` included, and its chapter is its lines. umtool shows it as a card row named by its lines; its words are edited in the manifest.

Under each pop is a synthesised boom, the title's the biggest, and under the tail a low swell; `"hits": false` makes the card silent. `"beat"` (0.4–2.5 seconds, default 0.7) sets the time from one pop — and its hit — to the next, the second tier and the tail's wait slowing with it; `seconds` may be left out for exactly the length the beats need, and a `seconds` too short for them is refused with that length rather than played faster. Put after the last clip, it joins with the ordinary crossfade and takes the cut's end fade. A line too long to fit the frame at its smallest size is refused with a sentence saying how many characters fit (a title holds 34). It is rendered once and re-rendered when its words change, `--chrome-only` included, and its chapter is its lines. umtool shows it as a card row named by its lines; its words are edited in the manifest.
+- **A report cut can go to black before its teaser, and the teaser rises out of the black.** A teaser entry's `"dip": { "fade": …, "black": … }` fades the whole frame before it — the footage, the on-screen deck, the posts feed and anything else drawn over the cut — to black over the previous segment's last `fade` seconds (0.3–4), its sound to silence with it, then holds `black` seconds (0–3) of black, taken to the nearest whole frame at the cut's frame rate. The teaser then opens out of it: the letterbox is already closed, the ground and its light stay dark until the first line slams in and come up with its hit, and a synthesised riser swells under the black into that first hit. The deck and the feed leave under the black instead of sliding away over the crossfade. The black is the start of the teaser's own segment, so the teaser is that much longer and nothing else moves; with a dip, the teaser's `seconds` counts from where the light comes up. The fade is made where the cut is joined, so `--chrome-only` changes it without rebuilding a clip. A dip anywhere but on a teaser, on the first entry, or out of range is refused with a sentence before a build fetches anything. A cut without a dip builds exactly as before.
- **A report cut with `transition: 0` builds when its output folder was given as a relative path.** The hard-cut concat listed its segments relative to the working directory, and ffmpeg reads that list relative to the list file's own folder, so every hard-cut build with a relative `--out` failed at the concat. The list now names each segment by its full path.
- **`archilyzer doctor` checks the image Build all builds sites in.** When a container engine answers, a new **build image** section says whether the image named under **Settings → Build pipeline** is there, when it was built and how big it is. It warns when the image is missing, or older than the last change to its Dockerfile, and prints the one command that rebuilds it. Build all still builds or refreshes the image itself before it builds any site; the warning tells you ahead of time that the next Build all will spend that time. With no container engine the check is skipped in one line, and with no corpus it is only a note. It never fails the doctor.
- **The site build image runs Node 22 and pnpm 11**, the versions the rest of the workspace runs on, instead of Node 20 and pnpm 9, which did not read the workspace's install rules. The next Build all rebuilds the image from its first step, reinstalling every dependency, before it builds any site.
@@ -27,6 +29,10 @@
- **A site can be private: built for reading on this machine, never deployed and never listed.** A site's settings have a new **Audience** choice (`audience` in `site.json`; only `"private"` is written). A private site is refused by every deploy — **Build & deploy**, **Deploy**, `archilyzer deploy site`, `pnpm ops build-deploy` and `deploy-site`, **Build & deploy all** (which builds it and skips its deploy) and `docker/publish-site.sh` — before anything is uploaded, in a sentence naming the audience; **Build** still builds it. It is left off the homepage, the hub and every other site's footer whatever **List on the Archilyzer homepage and hub** says, it publishes no hub URL, and its `corpus.json` says `"audience": "private"`, so a build of it is refused too if the site is switched back to public before it is rebuilt. Point the MCP at a private site's build to ask about what only it holds. Needs a rebuild and restart of the editor.
- **A site built on the host right after another site no longer ships that site's channel list.** A site's **Build** (and Build all without containers) composes every site into the same folder, and the step that copies a site's summaries, stats and duplicates was skipped when that site's own data had not changed, even though another site had composed there since. The site then went out with the other site's channel list and stats. Those steps now run again whenever another site composed last. Needs a rebuild and restart of the editor.
- **The hub no longer ships the data of the last site built before it.** **Build hub** built from the folder a site's build had just filled, so the hub carried that site's summaries, transcripts, posts and other data, and served them. The hub's build now clears every site's data first and uses the global search aliases, and **Deploy hub** refuses a hub build that still carries a site's data. Needs a rebuild and restart of the editor, then a rebuild and deploy of the hub.
+- **The dashboard and `/jobs` keep answering while a channel's report is regenerated.** Regenerating a report walks every video of the channel inside the editor, and two regenerations of channels with a few thousand videos, running side by side, kept `/`, `/channels` and `/jobs` from loading for over an hour. Regenerations now run one at a time, on their own `refresh-report` queue on `/jobs` — a channel's own **Refresh report** included, which now waits its turn there too: it waits up to 15 seconds, then says where its job is instead ("Queued behind 3 report regenerations — the report updates when it finishes (job …).") and the page catches up when it runs, and a regeneration that fails now shows its reason under the button; a channel whose report is already waiting is not queued a second time, whether the request came from a finished job, **Refresh report** or **Update all reports**, and a change made while a channel's report is being regenerated queues one more regeneration after it rather than being missed; and the walk pauses between batches of videos so pages are served in between. **Update all reports** answers as soon as the regenerations are queued, and the reports land one after another; `pnpm ops refresh-report` answers with the job ids for both a single channel and `{"all":true}`, which `--wait` follows. Needs a rebuild and restart of the editor.
+- **The operations pages share one count of the lanes' pending work.** Every open operations page asks for the lanes' status every 3 seconds, and each request used to count every lane's pending videos afresh from every channel's report. That count is now made once and handed to every request in the next 3 seconds. Changing a lane's rules, a focus or a channel's priority counts again at once; otherwise a pending count can be up to 3 seconds behind a report that was just rewritten or a video a lane just picked. A lane's hold, its runner and its picks are still read fresh on every request.
+- **Jobs a stopped editor left "running" are closed when it starts again.** A job that was still running when the editor's process ended (killed, crashed, or shut down before the job had finished unwinding) kept "running" in its record for good, and `/jobs` listed it as archived. On start the editor now marks each one **cancelled**, with "interrupted: the process running it stopped before it finished" as the reason on the job's page, and its end time is the last time its log was written. Nothing is run again; **Retry** works as for any cancelled job. A job that another live process is running, such as `archilyzer run`, is left alone, and the same check now keeps the start-up pass from closing that process's queued jobs. Such leftover jobs never blocked a media move.
+- **A channel's text stays on the fast disk when its media moves, so a slow or unplugged media drive no longer holds its transcripts.** A channel's big files — the audio and the raw live-chat replay — can now live in the channel's own `media` folder, on this disk or another, while its transcripts, cues, metadata and every other small file stay in `data/` where they always were; each big file that moves leaves a small link behind, so everything that opens it by name still finds it. New downloads, transcodes and live-chat normalizes put their big files there as they finish, and every cleanup that deletes audio removes the file the link points to, not just the link. What that changes when a media drive is stalled, unplugged or mid-move: **the index and stats builds never wait on it or are held by it** (a live chat whose transcript cues are out of date keeps the cues the last build read until the drive answers), the channel's report still refreshes (its media size reads as unknown until the drive answers), **digests keep running — even during a move of that channel's media** — and so do normalize, the availability checks, the metadata scan and clip eviction. Transcription, downloads, the backfill lane and anything else that opens the audio are held as before. **A channel moved the old way — its whole `data/` on the other drive — is now shown as "Media layout retired" and held by everything, the builds and digests included, until `archilyzer storage migrate-tier <channel>` brings its text home;** every refusal says so. Deleting a video from its page is refused while its channel's media drive is not reachable, so its audio is never left behind on the drive. Needs a rebuild and restart of the editor.
## [0.11.0] - 2026-09-30
- **Transcripts that arrived after a video was first seen are counted.** The stats behind the homepage, the hub and every site's charts were cached per video and refreshed only when the video's metadata changed, so a transcript that came later — a Whisper run days after the download, or a video downloaded after the last index build — never reached them, and a video with YouTube captions alone had no transcription date. Counts and charts were low; the homepage could show a site with 0 transcripts, 0 channels and 0 hours while it served its videos. A stat is now also redone whenever the index re-reads the video, every transcript has a date, and a captioned video is dated by when its captions arrived rather than by a later Normalize run, so its place on "Transcribed over time" can move. **After updating, rebuild and restart the editor before anything else:** until then, **Build stats dataset** runs the old code and would undo the new stats, while a site, hub or homepage build already runs the new code — and the first stats build of any kind re-reads every video once (about 10–30 minutes on a large archive; it can be stopped and picks up where it stopped). Then build the index, the stats, the homepage, the hub, and the sites.

+// 3,260-video channels in its own process, side by side, and three more
+// `refresh-report` metas still read `running` hours after the process that ran
+// them was gone. The first case below is the first half: two channels whose

+// not, and neither stops a media move.
+//
+// THE BUDGET IS 5 s, OR THREE TIMES WHAT THE SAME PAGE TOOK JUST BEFORE THE
+// REGENERATION, WHICHEVER IS LONGER. The suite runs under `next dev` on a
+// machine other suites and builds share; at a load average of 30 a page that
+// renders in 0.3 s on a quiet machine takes 2–4 s with nothing regenerating at
+// all. What this pins is that the regeneration does not starve the pages, not
+// how fast the machine is — so the idle measurement taken a moment before sets
+// the floor, and on a quiet machine the budget is simply 5 s. CAPPED AT 15 s:
+// on a machine so loaded that idle pages take over 5 s, the floor stops
+// growing, and the case fails rather than stretching to hide starvation.
+//
+// What the case pins, honestly: the serial queue (read from the jobs' own
+// records) and starvation at the scale of seconds. The yield between chunks is

its `phase` is what lets an interrupted move resume, `deleteChannel` and `renameChannel` refuse
while it exists, and `clearRelocationMarker` (`:160`) removes it and nothing else.
+### Release 17 slice T1 — the media tier's model, and which guard holds what (2026-10-01)
+
+Supersedes, where they differ, the facts in the section above and in "The index build's hold",
+"`cues.mjs` carries a reachability twin" and the drive-health notes below; those passages are kept
+as they were measured.
+- **The model.** A big file — `isTierable(name)`: `audio.<ext>` and `transcript.live_chat.json`, never
+ `source-media.*` or a partial (`common/lib/mediaTier.ts`, pure; `classifyEntry` is media / text /
+ scratch by NAME) — may be a RELATIVE link `data/<id>/<name> -> ../../media/<id>/<name>`;
+ `channels/<slug>/media` is a real dir (tiered in place), ONE absolute link to `<root>/<slug>/media`
+ recorded as `config.mediaDir` (relocated), or absent (classic). `data/` is always a real dir on the
+ corpus disk. The hook (`tierMediaFile` & co., `lib/mediaTier-server.ts`) is called after every
+ media finalisation (transcode, both download-outcome writes, a batch `runYtdlp` mode, a live-chat
+ normalize that wrote — not the export build's archive pass) and never throws; the bytes are placed by
+ a hard link (same disk) or an atomic copy before one rename swaps the name, so a crash never leaves the
+ name missing; the link carries the file's mtime (`lutimes`), and the
+ live-chat freshness check and the index's sub-track key (`subsMs`) `lstat` a tierable name, so the
+ index's scan never reaches the media drive; when a tiered live chat's cues are stale the index reads
+ the raw only while the channel's media is `ok`/`in-place` — one `stat` probe through `onDrive(mediaDir)`
+ (the watchdog's budget is sized for a stat), then a direct read — and otherwise keeps the cues the last
+ build held, or, with none, stores `subsMs: null` so the next build retries (`buildIndex.test.ts` (k): a
+ stalled drive, nothing asked of it; (l): the retry).
+ An EXDEV tier gives the copy the file's times, so `stat` and `lstat` agree. Every deleter of
+ a video-dir entry goes through `removeMediaFile` / `removeVideoDirMedia`.
+- **`inspectChannelMedia`** now describes the `media` link + `mediaDir`, returns `mediaLink` and
+ `text: { dir, readable }`, and has a seventh status, **`legacy`**: a `data` link or a recorded
+ `dataDir` (the retired whole-directory layout), answered without a call to the far drive, text
+ unreadable. Memo key: slug + `mediaDir` + `dataDir`.
+- **Two guards.** `assertChannelMediaReachable` (only `ok`/`in-place` pass) for a kind with
+ `needsMedia` ("opens or writes the BIG file"); `assertChannelTextReadable` (passes unless `legacy`,
+ `data/` not a dir, or a marker with `scope: "tier-migration"`) for a kind with the new `needsText`
+ (14 kinds flipped, pinned in `jobs/jobKinds.test.ts`). `runManagedFunction` asks the one the kind
+ declares, at enqueue and at start.
+- **Who is held by what.** The index and stats builds, the snapshot, `normalizeAllTranscripts`,
+ `saveShardConfigAction`, clip eviction and the digest batch read the TEXT tier and hold only on an
+ unreadable text tier; the digest lane holds on `isTextHeld` (= `legacy`) or unreadable text
+ (`isChannelHeldForLane`, `controller/autoRunner.ts`); transcription, download and backfill lanes,
+ the backfill batch and `normalizeAllLiveChat` keep the media hold. A media move's marker
+ (`scope` absent or `"media"`) holds media writers only; `channelWriters(slug, { mediaOnly })`
+ answers that set.
+- **The snapshot's bytes** are three siblings: `totalMediaBytes` (tierable names, through one
+ `onDrive(mediaDir)` per video for the links; ABSENT, with `totalAudioBytes`, when the media tier
+ could not be read), `totalTextBytes` (new), `totalClipsBytes` (no longer inside media).
+- **`onDrive` by file kind.** `channelMediaStall` keys on `mediaDir` (else the retired `dataDir`);
+ `channelTextStall` on the retired `dataDir` only. `readChannelStat` and the recency tail reads pass
+ a drive only for a legacy channel. `rootOfUnknownPath` strips `<root>/<slug>/media` and `/data`.

+ `posts.width` 600 wide, flush with the right edge and the top, down to the deck — 600×890 at
+ (1320, 0). The footage is as large as fits in the 1320×890 left of it with `posts.inset` 24
+ clear on every side, the frame's aspect, centred: 1272×716 at (24, 87) — 66 % of the frame's
+ width (the deck alone: 1574×886, 82 %). Gap footage → column 24 px. `top-left` mirrors it. A
+ feed whose footage would be under half the frame's width is refused. Inside the column: 22 px
+ side padding, a 66 px header from y 26 (platform pill, the handle at 26 px or "Posts" over
+ several authors, an "n of N" count, "posts as the timeline reaches them"), a rule at y 102,
+ the stack from y 120 to 22 px off the bottom (748 px). Cards are the popup's design sized for
+ the column: 556 wide, 6 px rail, 24 px words on 33 px lines (≈ 30 characters a line),
+ `maxLines`, the date at 18 px (handle and platform only with several authors), the
+ `qrSize` 120 QR in a 148 px cell.
+- **Timing:** post j of k on a clip ticks in at start + D + step·j, step = min(`seconds`,
+ (A − start − D)/k), A the clip's outgoing transition. D counts on the first entry too, which
+ has no incoming dissolve (the popup's first clip uses 0). The schedule carries `in` per post and
+ `layout: "feed"`, only when there are posts to draw.
+- **Motion** (`FEED_MOTION`): at `in` the cards already in move down by the new card's height

+ fades as it moves (0.45 s) and is gone: a card is either whole in the column or out of it.
+ The empty state fades with the first post. Over a hidden-deck segment the column slides
+ 624 px out of the frame's right edge on the deck's own times (`deckChoreography`'s visibility).
+- **Framing is the build's, per segment, and recorded:** a feed cut frames clips, stills and
+ shown cards into the feed's box; `framing: {layout, box}` in each framed segment's
+ `<id>.cut.json`. `--chrome-only` over segments whose box is not the cut's is refused, naming
+ each; a record-less segment counts as the deck's. Switching layouts is a normal build with
+ `--skip-fetch`.
+- **The feed is one region for the whole cut**, `chrome/feed[-frames]` (`feed-preview`,
+ `feed-from<s>`), cached like the deck's, laid like the deck's (`-reinit_filter 0`,
+ `format=rgba`, `shortest=1`) after it; the build checks it is as many frames as the deck's.
+- **umtool:** the preview's backdrop is a built segment carried from the box its record names
+ into the feed's (or the neutral frame drawn in the feed's box); the feed's iframe is up for
+ the whole scrub.
+
+Gates:
+
+- Unit: `chrome-feed.test.mjs` 16 (geometry, validation, `feedOn`, the feed schedule's tick-in
+ times, popup/no-posts schedule identity, `feedCues` stagger/push/overflow/highlight/visibility
+ and seek-safety, the page's nodes, escaping, cue times and no remote URL, the window, framing
+ and `framingProblems`, the overlay chain, compose-chrome's feed region through a stub), and 6
+ in `onscreen.test.mjs`/`serve.test.mjs`.
+- Identity, against 07d1fa08's modules over the ferret manifest: the popup, the hard-cut popup,
+ no posts, and a feed with no posts give byte-equal schedules, xfade graphs, overlay chains and
+ framing filters. `--only c07 --skip-fetch` without `render.chrome`: md5
+ `6a92235fa12ca181bb81993129c9ee9d`.
+- Ferret, scratch copy with `posts.layout: "feed"`, a FULL `--skip-fetch` build (segments
+ reframed) from cached windows: 356.7 s (no holds; the popup cut was 366.7 s), video 356.700 s
+ and audio 356.700 s; verify-build ok — deck 10,701/10,701, feed 10,701/10,701, 7 posts, no
+ hold, teaser 210/210; 18 chapters. Posts in at 25.7 / 29.7 (c03), 124.6 / 128.367 / 132.133
+ (c06, 3.77 s apart: c06 is short), 219.333 (c12), 285.533 (c17). QR 7/7 posts (each read off
+ its settled frame) and 17/17 deck. The column overflows at c06's posts (the c03 cards fade out
+ at the bottom). Build 52.5 min wall clock under a load average of ~25: the deck rendered in
+ 309 s, the feed in 487 s (1.2 GB of frames), the teaser in 159 s.
+- Repo gates on 211f0d87: workspace tsc clean (69 s); `test:scripts` 389 pass, 2 skipped (391);
+ capped umtool `next build` with the corpus linked exit 0 (41 s; 50 s on 220a84f5), link
+ removed. umtool e2e `onscreen-posts onscreen clip-bench build projects`: 96 passed (4.9 min,
+ after 27 min in the queue). A first run on 220a84f5 while the ferret build encoded (load ~25)
+ gave 87 passed, 9 failed — clip-bench and projects timeouts, none in the onscreen specs, both
+ feed tests green — and passed whole once the encode was done.
+
+Found and left:
+
+- **The popup page's clamp regex reaches the page as `/s+$/`** (the template literal eats the
+ backslash; quirk recorded). It runs only for a clamped card whose later paragraphs were dropped
+ after one that fit exactly, and strips trailing letters "s" rather than spaces. Not fixed here:
+ it would change the popup page and its cached windows; the feed's page writes `\\s`. (Fixed
+ after the F2 review: "Dip F2, as built", "Fix pass after the review".)
+- A card is in the feed whole or not at all, so an overflowing column can show a gap at its
+ bottom (on ferret at 133 s: 216 px free under two cards, the third needing 288).
+- The umtool preview shows the feed's composition and frames the backdrop in the feed's box; it
+ does not show the segments reframed (that is the build's), so a backdrop built for the deck is
+ carried, scaled, into the feed's box until a build reframes it.
+
+
+## Teaser V1, as built
+
+Branch `deck/teaser-v1` from 07d1fa08. The ask: a little more delay between the teaser's hits, and
+variation clips to judge before the full stitch.
+
+| Commit | What |
+|---|---|
+| 6869bbc7 | `deck.mjs`: `TEASER_BEAT` (0.4–2.5 s), `teaserMotion(beat)`, `teaserSeconds(entry)`; `teaserTimes(lines, tail, m)` no longer compresses and reports `need`; `validateTeaser` checks `beat` and refuses a `seconds` short of `need`; `estimatedDuration` of a teaser is `teaserSeconds`. chrome-teaser, compose-chrome, verify-build and `buildTeaserSegment` (now exported) read `teaserSeconds` / `teaserMotion`. Tests in `chrome-teaser.test.mjs` and `teaser-audio.test.mjs` |
+| 8a0b1b7e | README (`beat`, `seconds` optional) and the teaser's `[Unreleased]` bullet amended in place |
+
+Rulings, as built:
+
+- **`beat`** is the seconds from one line's pop to the next, hits included; default
+ `TEASER_MOTION.gap` (0.7). The second tier's delay stays 3/7 of the beat and the tail's wait
+ 8/7 (the default's 0.3 and 0.8 of 0.7), so a slower beat is the same rhythm slowed. The first
+ landing (timed to the dissolve), the slam's hit and settle, the tail's 1.7 s fade (and its
+ swell) and the 1.2 s end room do not scale. The hits are still `teaserHits` from `teaserTimes`.
+- **Nothing is squeezed.** A `seconds` shorter than `need` (the last pop, the tail's fade, the
+ 1.2 s hold) is refused with the length needed, rounded up to a tenth. Without `seconds` the
+ card is that length, at least 3 s; one that would need more than 20 s is refused.
+- `teaserTimes` keeps `scale` (always 1) and `T` (now only rounding): the page carries `scale` in
+ its data, and `need` is stripped from it, so a teaser without `beat` — or with `beat: 0.7` —
+ composes a byte-identical page. A test pins the ferret page's sha256 at 07d1fa08.
+
+Gates on 8a0b1b7e:
+
+- Workspace tsc clean (21 s). `test:scripts` 370 pass, 2 skipped, 2 failed: the queue-lock FIFO
+ and banner cases under load; `queue-lock.test.mjs` alone 11/11, three times.
+- Capped umtool `next build` with the corpus linked: exit 0 (58 s), link removed.
+- Byte-identical without `beat`: the ferret teaser's frames key is `b8ebcaf5…` at 07d1fa08, at the
+ tip and with `beat: 0.7`; the segment key `7c87943c…` the same at both. A fresh render at the tip
+ wrote 210 frames whose PNGs are byte-identical to the ones the cut was built from, and its
+ `fin.mp4` is the same file as the cut's (same sha256, same decoded video and audio md5).
+
+The variants (scratch build through `buildTeaserSegment`, `cutJoins`, `cutOffsets`, `xfadeGraph`;
+the deck's own frames laid over c20; trimmed to c20's last 3 s; the encode's `encodeArgs`):
+the reference is the manifest's entry, and the others keep its still hold after the tail
+(about 1.05 s past `need`), so their `seconds` grows. The manifest's `seconds: 7` holds beats up to
+about 0.99; at 1.05 and 1.3 it is refused with 7.2 and 8.1.
+
+| Beat | `seconds` | `need` | Clip | Hits in the teaser's clock (overline, title, second tier, kicker; swell) |
+|---|---|---|---|---|
+| 0.7 (none set) | 7 | 5.95 | 9.5 s | 0.75, 1.45, 1.55, 2.45; 3.05 |
+| 0.9 (+29 %) | 7.7 | 6.66 | 10.2 s | 0.75, 1.65, 1.84, 2.94; 3.76 |
+| 1.05 (+50 %) | 8.3 | 7.2 | 10.8 s | 0.75, 1.80, 2.05, 3.30; 4.30 |
+| 1.3 (+86 %) | 9.1 | 8.09 | 11.6 s | 0.75, 2.05, 2.41, 3.91; 5.19 |
+
+Each clip's video and audio are the same length; the measured level onsets (an 8 dB rise per
+50 ms window) land on the overline, title and kicker hits at every beat — the second tier's
+lighter hit falls inside the title's decay, as designed.
+
+## Dip F2, as built
+
+Branch `deck/finale-dip` from e04795b7 (main 90bd8384 with `deck/feed-f1` and `deck/teaser-v1`
+merged). The ask: about one to two seconds of fade to black between the last clip and the
+teaser finale, for a little suspense, and a good transition from black into the finale. A
+teaser entry's optional `"dip": { "fade": <s>, "black": <s> }`.
+
+| Commit | What |
+|---|---|

+| 95663453 | build-video: `withCutEdits`' `dips`, `cutJoins` puts `dip` on the segment before a dipped teaser, its sound by `endFadeAudioFilter`; `dipWindows`, `dipVideoFilter`, `dipParts` laid last in every concat path (`xfadeConcatArgs`, `hardCutFilterArgs`, `applyChromeArgs`, `applyRail`, `previewFromSegmentsArgs`); `concatRecordText` names a dip; `buildTeaserSegment` takes the transition; the teaser's audio graph gains the riser's layer |
+| 29d6581f | The riser at gain 0.22; `dip.test.mjs` |
+| f002d76f | The picture by `fade` to black instead of `geq` (the `geq` form kept for a preview window that opens inside the fade); README |
+| 47761930 | The join into a dipped teaser holds the outgoing segment through the overlap (`xfade` custom `expr='A'`, `acrossfade` `nofade` both sides) |
+| (this) | quirks, one `[Unreleased]` bullet, this section |
+
+Rulings as built:
+
+- **The fade is the whole finished frame.** Over the previous segment's last `fade` seconds,
+ ending on its last frame `last` (frame `s = last − n`, n = `endFadeFrames`, is the last
+ untouched one), ffmpeg's `fade` out to black on the composite after every overlay (deck, feed,
+ posts, rail), enabled on frames (s, until): `until = last + 1 + round(black·fps)`. A fade to
+ black stays in yuv420p (luma 16, chroma 128); only a coloured fade needs RGB. `geq` was the
+ first form and cost about 0.25 s per 1080p frame (quirks); it remains only for a
+ `--chrome-preview` window that starts inside the fade, where `fade` cannot start. The sound is
+ `endFadeAudioFilter` on that segment's join, silent at the last frame's time. Both are made
+ where the cut is joined, so `--chrome-only` changes them; the hard-cut record names the dip.
+- **No dissolve into a dipped teaser.** Over the overlap the outgoing segment plays untouched
+ and the teaser takes over at its end, under the black. With the ordinary dissolve the footage
+ was blended with the teaser's black lead and darkened by (1 − p)(1 − k) while the deck and the
+ feed, over it, darkened by (1 − k) alone: measured on the ferret ending, the panels stayed
+ visibly lit over a nearly black picture through the last half second of the fade. The
+ overlap's length is unchanged, so every offset, chapter and schedule time is too.
+- **The black is the teaser's own lead.** `teaserLead = D + black` (D the transition as built,
+ 0 under `--no-xfade`): its page is black and its sound silent but for the riser until then;
+ the segment is the lead plus the card. No hold anywhere. The deck and feed hide in an instant
+ at `dipHideAt` (the dipped segment's last frame, black), not over the overlap.
+- **The rise.** Bars closed from the first frame, `autoAlpha` 0 → 1 with the light; a black
+ `veil` over the ground and the leak, under the words: 1 → 0.45 from the end of the black to the
+ first impact (0.35 s, `power2.in`), → 0 over 0.3 s after it (`power2.out`). The first line's
+ slam starts 0.15 s after the black (the impact 0.35 s), so with a dip the card needs 0.4 s
+ less than without, and `seconds` (when set) is the card's from the end of the black. The leak
+ enters after the lead. A riser: a sub 30 → 55 Hz (squared envelope) and noise band-passed
+ 400 Hz–6.5 kHz (cubed), up to 1 s, ending on the first impact, released over 40 ms; its last
+ 100 ms measure −18.3 dBFS RMS against the hit's −13.0. The dipped teaser (B) measures
+ −19.7 LUFS integrated, peak −6.0 dBFS; without a dip it measures −19.4 LUFS at the same beat.
+- **Without a dip nothing changes:** the ferret teaser's page sha256 at 07d1fa08 still holds
+ (`chrome-teaser.test.mjs`), the audio graph has no riser layer, every concat path writes the
+ graph it did (`dip.test.mjs` compares them), and the schedule has no `dip` key.
+
+The ferret ending at `beat: 1.05`, no `seconds` (card 6.8 s), D 0.5. c20 is 7.0 s (frames
+0–209, its last at 6.967 s); the teaser starts at 6.5 s.
+
+| Dip | Teaser | Fade (frames → black) | Black to | Veil lifts | First impact | Riser | Cut |
+|---|---|---|---|---|---|---|---|
+| A `{0.9, 0.4}` | 7.7 s (lead 0.9) | 6.067 → 6.967 | 7.4 | 7.4 | 7.75 | 6.75–7.75 | 14.2 s |
+| B `{1.2, 0.6}` | 7.9 s (lead 1.1) | 5.767 → 6.967 | 7.6 | 7.6 | 7.95 | 6.95–7.95 | 14.4 s |
+| C `{1.6, 1.0}` | 8.3 s (lead 1.5) | 5.367 → 6.967 | 8.0 | 8.0 | 8.35 | 7.35–8.35 | 14.8 s |
+
+The previews (scratch copies of the project with the timeline `[c20, fin]`, the feed layout,
+`render.endFade` 1, built with `--skip-fetch` from the cached windows, nothing fetched): video
+and audio the same length in each (14.200, 14.400, 14.800 s). Every frame from c20's last
+through the end of the black has YMAX 16 across the whole frame, and the mid-black frame
+Y 16/16, U 128/128, V 128/128 (signalstats), deck panel and feed column included; the
+contact sheets show the panel and the column dimming with the footage at mid-fade. The sound in
+C is −135 dBFS from c20's last frame to the riser.
+
+Gates:
+
+- Workspace tsc (`pnpm -r exec tsc --noEmit`) clean (44 s, on a loaded machine).
+- `test:scripts` on 47761930: 412 tests, 409 pass, 2 skipped, 1 failed: the queue-lock banner
+ case under load; `queue-lock.test.mjs` alone 11/11, three times. `dip.test.mjs` 17/17; the
+ report-to-video suite alone 291/291.
+- e2e and the capped umtool `next build` are run at the merge, not here.
+
+Found and left:
+
+- At the bottom of the veil's lift the dark radial ground shows 8-bit banding rings for a few
+ frames (x264 at crf 21 over a gradient under a near-black veil); the grain sits above the
+ veil, where an overlay blend over black adds nothing.
+- `deck.motion.in` longer than the transition no longer matters to a dipped boundary (the hide
+ is instant), but a popup-layout clip's posts still leave over the overlap as they always do,
+ now under the fade.
+
+### Fix pass after the review
+
+The read-only review of 90bd8384..76c93607 (F1, V1, F2) said SHIP, with M1 (the umtool e2e and
+the capped `next build` for F2, owed at the merge) and eight LOWs. L8 (a dip's `black` alone
+changes the hard-cut prerail record) is left: a `black` change rebuilds the prerail anyway.
+
+| Commit | What |
+|---|---|
+| 6dc0c464 | L1: the popup page's clamp writes `\\s` in its template, so the page gets `/\s+$/` and a clamped quoted paragraph ending in "s" keeps it. A test reads the regex off a composed page. The popup page's hash changes, so cached popup windows re-render once |
+| 3e3980c4 | L2: `--chrome-only` / `--chrome-preview` check the segments on disk (all but the teasers', which are built next) and `framingProblems` before rendering any teaser. A test drives `buildVideo` over deck-framed segments under a feed with a stub renderer that is never run |
+| b096557c | L4: `dipOf(entry, fps)` snaps `black` to whole frames (`snapToFrames`; a value already whole, 0.6 at 30 fps, is returned as given). `teaserLead`, `teaserSeconds`, `teaserMotionOf`, `teaserHits`, the page, the schedule's `dip` and `cutJoins` take the render's fps, so the lead, the page's rise, the frame count and `dipWindows`' `until` agree (0.45 at 30 fps is 14 frames, 0.4667 s) |
+| 2504823b | L5: the teaser's record (`<id>.teaser.json`) names the `transition` it was built at, and verify-build counts its frames at it; an older record falls back to the schedule's, then 0 under verify-build's new `--no-xfade`, which umtool's driver passes whenever the build had it |
+| 41980cb9 | L6: wording only. A feed post ticks in at its clip's start + D on every clip, the first included; the JSDoc, the page module's header, the README, the `[Unreleased]` bullet and the timing line above say so. No schedule changed |
+| e23c9b89 | L7: the umtool layout hint says a switch takes a full build (cached windows reused) and re-render on-screen is refused until one has run. No e2e spec asserts the hint's text |
+| 2093ef9b | L3: documented only (quirks): `overCards` toggles on full-frame cards are not in the framing record, and `scroll` / `chart` / `ledger` are never framed, so under the feed with `overCards: "show"` the column covers their right third |

+### Slice D0, as shipped — the dashboard answers while a snapshot regenerates (2026-10-01)
+
+Branch `r17/dashboard-answers` off `main` `7f4901f1`, worktree `~/Projects/r13-lows-editor` (editor 5401,
+test 5411, export 5410 — `pnpm wt list`'s block #24), one Opus implementer. Scratch files `D0-*` in the
+job's `tmp`. The plan is Step 0b above.
+
+**What was found before building** (the corpus only read; one video dir's text copied to scratch for the
+profile).
+- **The walk did yield — on every file read.** Each video's unit awaits its reads, so the loop turned
+ between them; what the walk does ON the loop is parse. A CPU profile of `generateChannelSnapshot` over
+ 300 copies of one omnibased video dir's text (metadata 0.62 MB, cues 0.62 MB, two 2.9 MB VTTs):
+ `readNormalizedTranscript` (the cues parse, `readTranscriptCoverage`) 1,037 ms self, `readWebpageUrl`
+ 791 ms self, everything else in the walk under 70 ms. `readWebpageUrl` is the reconcile pass at the
+ walk's start (`reconcileVideoDirs.ts`): it reads and parses EVERY `metadata.info.json` for its
+ `webpage_url`, one at a time, on every regeneration.
+- **One walk alone does not starve the pages.** Built and served by `next start` (loopback, a scratch
+ corpus of one 2,000-video channel, load average 24), with this slice: the regeneration took 26 s, and
+ `/` answered in 0.28–1.6 s and `/jobs` in 0.18–0.81 s, polled every 2 s throughout. Under `next dev`
+ at a load average of 32–35 the same walk took 118 s and the answers ran 0.3–28 s; with `main`'s five
+ files swapped back, 2.0–12.5 s. On this machine, under the dev server, one regeneration does not
+ separate the two, and an isolated tsx micro-benchmark (800 such dirs, three interleaved pairs, load
+ 25–35) put the chunked walk and `main`'s inside each other's noise (loop delay max 300–860 ms either
+ way).
+- **So the hour-long outage needed more than one walk**, and the live metas show the rest: two walks side
+ by side (the empty queue key), the omnibased one on the platter through `onDrive` (four slots per
+ location, so every page read of that drive queued behind the walk's units), two regenerations of
+ omnibased four seconds apart in the restarted process (`01M3WHY8…`, `01M3WHYC…` — two passes racing
+ between the registry check and the record's registration), and the auto-queue status poll recomputing
+ behind all of it. D0 closes the three it owns: one queue, a per-slug dedup that covers the enqueue in
+ flight, and the status memo. The platter half is T1's (text reads leave `onDrive`).
+- **The ghosts never held a move.** `channelWriters` reads this process's registry only, never a meta,
+ and the registry is in memory: a meta a dead process left `running` was never a writer. `/jobs`
+ listed such a job as `archived` (`listJobs`: a non-terminal meta not in the registry). Harmless to a
+ move, misleading on `/jobs`; the boot pass now closes them.
+- **What a SIGTERM'd process leaves behind today** (`shutdownCancel.ts`, "graceful shutdown only"): the
+ reaper cancels every live job and re-raises the signal at once, without waiting. A queued job keeps
+ `queued` on disk on purpose (the boot pass settles it). A running managed job's terminal meta is
+ written only when its function returns (`streamCommand.ts`, the `.finally`); `generateChannelSnapshot`
+ takes no signal, so a regeneration never returns before the exit, and its meta stays `running`. A
+ SIGKILL leaves the same, and orphans children.
+
+**What it does.**
+- **The walk yields between chunks.** `generateChannelSnapshot` maps its video dirs through
+ `mapInYieldingChunks` — chunks of `SNAPSHOT_YIELD_EVERY` (32: two full waves of the 16-wide limit), one
+ `setImmediate` between chunks. The unit body is untouched: the diff in that file is the helper, the
+ constant and the call's two lines, so T1's merge is trivial.
+- **One regeneration at a time, once per channel.** `snapshotScheduler.ts` gains `REFRESH_REPORT_QUEUE`
+ (`"refresh-report"`: a non-empty key is the registry's existing concurrency-1 serialization, so no new
+ mechanism) and `startRefreshReport(paths, slug)`, the one entry point: a slug with a `refresh-report`
+ queued, running or being enqueued (a `starting` set on the scheduler's global state, held across
+ `runManagedFunction`'s awaits) is answered `info` with `REFRESH_REPORT_ACTIVE`. The debounced pass and
+ **Update all reports** (`refreshAllChannelSnapshotsAction`, `editor/app/channels/actions.ts` — not in
+ the slice's file list and owned by no other slice) both go through it, so they dedup against each
+ other; the action still reports a skip as "already running". The job body is the scheduler's (it bumps
+ `generation`, which the action's copy did not).
+- **The auto-queue status poll shares one fold.** `common/views/autoQueueStatus.ts` gains
+ `singleFlightMemo` (concurrent callers share the computation in flight; a landed value is reused for
+ `AUTO_QUEUE_STATUS_MEMO_MS` = 3 s from when it LANDED; a rejection is not memoized; `clear()` detaches
+ an in-flight computation) and `autoQueueStatusMemo()` on `globalThis`. `buildAutoQueueStatusPayload`
+ is unchanged. The shell (`editor/app/operations/status.ts`) memoizes the snapshot-derived half only —
+ the channel briefs and the four lanes' `computeLeafPending` — and reads the priority view, the state
+ document, settings, the pool and the runners fresh. The e2e reset route drops the memo with the other
+ singletons.
+- **Boot closes the running metas a dead process left.** A meta now records `pid` (`jobMeta.ts`, owned by
+ no slice). `bootQueuedJobs.ts` gains `settleRunningJobMetas`, run from `instrumentation.ts` on every
+ boot (idle and test server too: it re-queues nothing, and it does not wait for the storage pass): a
+ `running` meta from before this boot, not in the registry, whose writer is gone is closed `cancelled`
+ with `cancelReason` "interrupted: the process running it stopped before it finished", `endedAt` = its
+ log's mtime (the last moment it is known to have run), else now. **The status:** `cancelled` +
+ `cancelReason` already is this file's terminal state for "the server went down under it", and every
+ reader (listJobs, `/jobs`, the job page's "Cancelled because", Retry) handles it — so there is no new
+ `interrupted` status. **The dead-process test** (`writerIsGone`): metas carried no pid or host, and
+ "predates this boot" alone is not reliable here, because `archilyzer run` (`bin/run-operation.ts`) runs
+ jobs offline into the same `.jobs/`. Gone = no pid (written before this release), or this process's
+ own pid (a container's editor restarts as the same pid; this process's own metas are already excluded
+ by `bootedAt` and `isLive`), or `kill(pid, 0)` → ESRCH (EPERM counts as alive). A live pid is left
+ alone. The queued pass now applies the same check. `channelWriters.ts` gains a comment saying why a
+ ghost cannot reach it, and a test pins it.
+- **e2e** `dashboard-answers.spec.ts` (two cases) and `/api/test/settle-running-metas` (POST, guarded by
+ `E2E_TEST_ROUTES`), which runs the running pass on demand: the e2e server boots once per suite.
+ (a) Two 600-video channels (one hardlinked ~400 KB `metadata.info.json` per dir, a Rumble archive so
+ each file is parsed twice) regenerated by Update all reports through the ops API while `/` and `/jobs`
+ are polled every 2 s: both reports land, the second job started when the first had ended (read from
+ their records), and every answer is inside the budget. (b) A `running` refresh-report meta with a dead
+ pid is closed as interrupted, one with a live pid (the test runner's) is left `running`, the job page
+ says "interrupted", and the channel's Move media completes.

+#### Gates (logs `$T/D0-*.log`)
+
+- **tsc** (all workspaces) clean at every commit.
+- **common:** **2,496/2,496** — new: `snapshotScheduler.test.ts` 2, `autoQueueStatus.test.ts` +5,
+ `bootQueuedJobs.test.ts` +4, `channelWriters.test.ts` +1. **Editor unit:** 109/109.
+ **test:scripts:** run 1: 301 passed, 1 failed, 2 skipped (304); rerun: 300 passed, 2 failed, 2
+ skipped. Every failure is in `queue-lock.test.mjs` ("prints a banner naming the holder while waiting",
+ "serves waiters in arrival order (FIFO)"), timing cases run at load averages of 16–30; the file run
+ alone passes 11/11, and the slice touches nothing under `scripts/`.
+- **Build:** the capped editor build with the corpus linked (`ln -sT`, `systemd-run --scope -p
+ MemoryMax=6G`, the link removed after): exit 0, 123 s, at `fef9ebc2`.
+- **e2e** (`jobs`, `channels`, `channel-storage`, `dashboard-answers`; `next dev`):
+ - run 1 at `fef9ebc2`: **23 passed, 2 failed, 16.7 min**. `dashboard-answers` (a) timed out at 5 min:
+ 2,000 videos under `next dev` at a load average of ~30 did not finish (the scratch-server measurement
+ above: 118 s for the walk alone, every answer slower). `channel-storage` "relocate a channel's media
+ to another root, and move it back" — the run's first test, on a cold dev server — timed out at 90 s
+ on its first request to the file route.
+ - run 2 at `fe1676c3`: **25 passed, 0 failed, 3.7 min** (34 min with the queue wait). (a) took 23.8 s:
+ nine polls of each page while the two regenerations ran, `/` 0.14–1.9 s and `/jobs` 0.34–1.6 s
+ (budget 5 s); (b) 7.8 s. The relocate case passed — run 1's failure was the cold first test.
+- **Numbers tool:** none.
+
+**Deviations from the plan, one sentence each.**
+- The chunk is 32, not 25, so every wave of the 16-wide limit is full (25 left each chunk's second wave
+ nine wide).
+- The memo covers the shell's snapshot-derived half, not the whole payload: memoizing it all would hold a
+ lane's hold, runner and picks up to 3 s behind a click, and specs read them straight after one.
+- The running-meta pass is in `bootQueuedJobs.ts` beside the queued one, not in `registry.ts`, which is
+ in memory and holds no metas.
+- "Interrupted" is `cancelled` + `cancelReason` (the existing terminal state for a job the server went
+ down under), not a new status.
+- `channelWriters.ts` gets a comment and a test, no code: a ghost cannot reach it.
+- The e2e budget is 5 s or three times the slowest idle answer measured just before, whichever is longer:
+ the dev server on this shared machine at load 30 takes 2–4 s a page with nothing regenerating, and the
+ spec pins starvation, not the machine's speed.
+- The spec regenerates two 600-video channels, not one large one: 2,000 did not finish in five minutes
+ under the dev server here, and two prove the serial queue from the jobs' records.
+
+**Found and left.**
+- The reconcile pass parses every `metadata.info.json` in full, on every regeneration, for one field — the
+ largest single cost of a walk. Reading only the head, or skipping a dir whose name is already canonical,
+ is a follow-up (`reconcileVideoDirs.ts` is not D0's).
+- `generateChannelSnapshot` takes no abort signal, so a Cancel or a graceful shutdown cannot stop a walk;
+ the chunk boundary is now the natural place to check one — a follow-up.
+- A meta whose pid has since been reused by an unrelated live process stays `running` on `/jobs` until
+ that process exits; a start-time check (`/proc/<pid>/stat`) would close it. Not worth it today.
+- `editor/app/jobs/[id]/page.tsx` and `JobRow.tsx` describe the cancel reason as the one "a restart left
+ queued"; it now also covers a dead process's running job. Comments only, left.
+
+**Changelog** (`editor/CHANGELOG.md` `[Unreleased]`): three bullets — the dashboard and `/jobs` answer
+while reports regenerate (one at a time, deduped; Update all reports takes the sum), the operations pages
+share one pending count (up to 3 s old; holds, runners and picks fresh), and jobs a stopped editor left
+"running" are closed at start.
+
+**Rollout note.** No `archilyzer run` may be in flight across the first editor restart after this ships:
+every meta written before it has no `pid`, so the boot pass reads its writer as gone and would close a
+still-running offline job's meta as interrupted (the live job rewrites it at its next meta write, but
+`/jobs` offers Retry meanwhile). The same holds across pid namespaces — an editor in a container judging
+a pid a host-side `archilyzer run` wrote, or the reverse, sees ESRCH. The release's rollout stops the
+editor for the migration anyway.
+
+#### Review (SHIP AFTER FIXES) and the fixes
+
+| Finding | Fix |
+|---|---|
+| H1 — the memo served pending counts folded from settings (lane policy and tree, `channelPriority`) up to 3 s stale against a fresh tree; the payload-reading specs were not run | `5b236f8c`: `singleFlightMemo.get(key, compute)`; the shell keys it on `JSON.stringify([settings.autoQueue, settings.channelPriority])`, time the only other expiry; only the latest-started computation stores (an old key landing late never overwrites); comments say what can be one poll late (a rewritten snapshot, the runner's in-flight set) and what is fresh; +1 test. The status-reading specs ran in the full suite below |
+| L2 — a change during a RUNNING regeneration was dropped until the next change (as on main) | `616a9ce2`: dedup only against a queued or starting regeneration (`isRefreshReportPending`), so a running walk gets one queued successor and no second; fire()'s trailing-edge comment is now true; +1 test |
+| L3 — the per-channel Refresh report walked in the request, outside the queue | `5509ccf4`: `refreshChannelSnapshotAction` (Refresh report, ops `{slug}`, e2e `generateReport`) starts a job through `startRefreshReport` and awaits it — or polls the one already queued for the channel — and returns the walk's error sentence (`onError`) as its `{error}`; the ops route's comment follows |
+| L4 — a queued refresh-report holds the Storage panel's Move (`mediaBusy.ts` counts queued jobs) | Not changed in D0, as ruled: T1's `mediaOnly` (refresh-report does not need media) clears it when T2's courtesy check passes it; to confirm at the T1/T2 merges |
+| L3 follow-on — `generateReport` (85 specs) now queues a job, which `/jobs` may draw before its default filter hides it | `7ba8cd41`: `bulk-actions.spec` "queues no job" leaves `refresh-report` rows out; `dashboard-answers` compiles the ops route (a 400 on `{}`) before measuring — its first compile held `/` 15 s once under load |
+| L5 — nothing pinned the yield; the e2e floor could grow without bound | `fea5b203`: `snapshotYield.test.ts` — a `setImmediate` probe queued during the first chunk runs before the second chunk's first unit (it fails with the yield removed, checked); 2 tests. The e2e budget is `min(max(5 s, 3 × slowest idle), 15 s)`, and the spec header says it pins the serial queue and gross starvation, not the yield |
+| L6 — the first boot after this ships closes a live pre-slice `archilyzer run`'s meta | The rollout note above |
+| N7 — `REFRESH_REPORT_QUEUE` beside the other queue keys | `616a9ce2`: defined in `lib/queueKeys.ts`, re-exported by the scheduler |
+| N8 — `operations/[id]/page.tsx`'s census comment claimed the payload's listing | `5b236f8c`: says it is the same listing only on a memo miss |
+| N9 — `requestCache.ts` said "no exception" | `5b236f8c`: one paragraph naming the memo and its bound |
+| N10 — `channelWriters.test.ts` conflicts with T1 (both append) | Keep both, at the merge |
+| the record and changelog | this commit: this subsection, the rollout note; the changelog's first two bullets say Refresh report waits its turn, a change during a regeneration queues one more, and a rules/focus/priority edit recounts at once |
+
+**Gates after the fixes.** tsc clean at every commit. **common 2,500/2,500** (+4: memo key 1, the
+successor 1, the yield 2). **Editor unit 109/109.** **e2e** — L3 makes every `generateReport` (85 specs) a
+queued job, so the whole editor suite rather than the two lists (it contains both), in three runs on a
+machine that ran out of memory (15 GB used, swap 19/19 GB; a parakeet transcription of the live editor
+beside several suites):
+ - run 3, the full suite (702 tests) at `fea5b203`: stopped at 374 passed, 8 failed, ~50 min, when
+ pages began to crash (`page.goto: Page crashed`). Two failures were D0's and are fixed in `7ba8cd41`
+ (`bulk-actions` "queues no job"; `dashboard-answers` (a): one `/` of 14.9 s at the moment the ops
+ route compiled, every other answer ≤ 4.6 s). The other six passed in run 4.
+ - run 4 at `7ba8cd41` (run 3's failures plus every spec file from `new-channel-onboarding` on, and both
+ lists — 69 files): **295 passed, 154 failed, 35.1 min** (54 with the queue). Every spec in both lists
+ passed — `jobs` 2, `channels` 8, `channel-storage` 13, `dashboard-answers` 2, `focus-banner` 3,
+ `auto-queue` 24, `lane-runner` 5, `channel-priority` 9, `operation-settings` 7, `backfill` 20,
+ `channel-work` 11, `ops-api` 23 — except `view-route`, which ran after a machine-wide OOM kill at
+ 22:41 took the test server (the kernel log names it, among browser tabs, the desktop session and the
+ live editor's transcriber): every test from the 300th on failed in under 2 s against a dead server.
+ Before it, four failures in `site-scope` (2), `sites-crud` and `social-channel` (the known 22–26 s
+ fetch-posts case).
+ - run 5 at `7ba8cd41`, the 25 spec files with a failure in run 4 (`view-route` included): **183 passed, 0
+ failed, 12.2 min** (13 with the queue).
+ So every editor spec has passed with the fixes in, across runs 3–5, and both lists in full.
+
+**test:scripts** was not re-run: the fixes touch nothing under `scripts/`.
+
+#### Re-review (SHIP AFTER FIXES) and the fixes
+
+| Finding | Fix |
+|---|---|
+| R1 — Refresh report and both ops forms waited for the whole serial queue, with no bound and no feedback (the CLI's fetch gives up at 300 s; the button dropped the action's result) | `5287e8c2`: `requestRefreshReport` (start, or find the queued job) and `waitForRefreshReport` (up to `REFRESH_REPORT_WAIT_MS` = 15 s → done, failed, or waiting with the regenerations ahead), `refreshReportWaitNotice`; `e491ec14`: the action returns `{ notice }` ("Queued behind N report regenerations — the report updates when it finishes (job …).") past the bound, `RefreshSnapshotButton` draws an error and the notice, `InlineActionButton` shows the notice neutrally, and Update all reports answers once queued; `7ae184bd`: ops `{ slug }` returns `{ ok, jobId, started }` (404 for an unknown channel) and `{ all }` returns the ids at once, as `_lib.ts` rules — `--wait` follows them |
+| R2 — the "already queued" branch reported success when that job failed, or when the slug was mid-enqueue | `5287e8c2`: the wait reads any job's end — a failure returns the job log's `[error]` sentence, whoever started it; a slug mid-enqueue is waited for (2 s) until its id exists; +2 tests |
+| R3 — `started.stream` left open | `5287e8c2`: `requestRefreshReport` cancels every stream it starts |
+| R4 — run 4's count | this commit: 154 failed, not 68 (the log's tally) |
+| the changelog | this commit: bullet 1 says what a long wait shows |
+
+**Gates after the re-review fixes.** tsc clean at every commit; **common 2,502/2,502** (+2); **editor unit
+109/109**; e2e `dashboard-answers`, `channels`, `ops-api`, `channel-work` (only these, as asked): run 6 at `7ae184bd`: **44 passed, 0 failed, 4.7 min**
+(dashboard-answers (a): 30 polls of each page while the two regenerations ran, every answer ≤ 3.1 s).
+
+**Merge of `main` `1d5c33bf`** (U1, export 0.11.1, XP) at `52446024`: two conflicts, both appends —
+this file keeps U1's and XP's record sections before D0's under `## Record`, and `editor/CHANGELOG.md`
+keeps every `[Unreleased]` bullet (main's, then D0's). Re-gated on the merged tree: tsc clean; **common
+2,519/2,519**; **editor unit 109/109**; e2e `dashboard-answers`, `channels`, `jobs`, `channel-storage`
+(run 7): **25 passed, 0 failed, 6.4 min** (23 with the queue wait; every dashboard answer ≤ 3.7 s).
+
+### Slice T1, as shipped — the classifier, the media link and the two guards (2026-10-01)
+
+Branch `r17/media-tier-model` off `main` `7f4901f1`, worktree `~/Projects/plans-export-header-first-search`
+(editor 4201, test 4211, export 4210 — `pnpm wt list`'s block #12), one Opus implementer, beside D0 and U1.
+Scratch files `T1-*` in the job's `tmp`. The plan is "The model (A′)" §§1–4 above plus the `channelWriters`
+option and the umtool twin; the mover and every editor surface are T2's.
+
+**What it does.**
+- **The classifier** (`common/lib/mediaTier.ts`, pure): `classifyEntry(name)` is `media` / `text` / `scratch`
+ by name over `mediaFiles.ts`'s anchored predicates; `isTierable` is narrower (`audio.<ext>` and
+ `transcript.live_chat.json` — never `source-media.*`, never a partial); `classifyVideoDir`. The table test
+ pins 32 names, the four the slice table names among them.
+- **The hook and the deleter** (`common/lib/mediaTier-server.ts`): `tierMediaFile` moves a finished big file
+ into `channels/<slug>/media/<id>/` and leaves the relative link `../../media/<id>/<name>` —
+ `tiered | left | already`; never throws; a classic channel, a dangling or stalled `media` link, a full disk
+ leave the file real; the per-video `mkdir` is non-recursive; EXDEV copies atomically; the link replaces the
+ name by a rename (no window with nothing there); a failed same-disk move is undone. `tierVideoDir`,
+ `tierChannelMedia({ since, createMediaDir })`, `removeMediaFile` (derefs only inside the channel's own
+ `media/<id>/`), `removeVideoDirMedia`, `channelMediaLink`, `relocatedMediaDir`, `tierLinkTarget`.
+- **Every media finalisation calls it:** `transcodeAudio` after its rename (so the app extraction, the
+ audio-checked download and the video page's Transcode), `downloadOneManaged` before both download-outcome
+ writes, `runYtdlp`'s five media-writing modes after the child returns (`since` the run's start, in a
+ `finally`), `normalizeLiveChat` after it writes the cues. **Every deleter derefs:** the three cleanup
+ sweeps, `purgeSupersededAutoSubs`, `backfillReacquire`, the app extraction's source discard, the audio-checked
+ source discard, `fixIncompleteTranscript` (both), and the video page's file delete, bulk audio removal and
+ directory delete (`removeVideoDirMedia` first). Grep gate
+ `git grep -n "remove(path.join(.*videoDir\|rm(path.join(videoDir" common editor`: **0 hits** (the module's own
+ `rm`s take a joined path).
+- **`config.json`:** `mediaDir` (CHANNEL.md regenerated by `bin/file-schemas-docs.ts`); `dataDir` documented
+ RETIRED and still parsed.
+- **`inspectChannelMedia`** describes `channels/<slug>/media` + `mediaDir`, returns `mediaLink` and
+ `text: { dir, readable }`, and has a seventh status, **`legacy`** (a `data` link or a recorded `dataDir`,
+ answered from the corpus disk alone, text unreadable, its detail naming `archilyzer storage migrate-tier
+ <slug>`). The marker parses an optional `scope` (`media` | `tier-migration`). Memo key: slug + `mediaDir` +
+ `dataDir`. `assertChannelTextReadable` beside the media guard; `isTextHeld`, `HELD_REASON.legacy`;
+ `channelMediaStall` keys on `mediaDir` (else the retired `dataDir`), `channelTextStall` on the retired
+ `dataDir` only; `rootOfUnknownPath` strips `<root>/<slug>/media`.
+- **Which guard holds what.** The index and stats builds, the snapshot, `normalizeAllTranscripts`,
+ `saveShardConfigAction`, clip eviction and the digest batch ask the text tier (`text.readable` /
+ `assertChannelTextReadable`); the digest lane is held by `isTextHeld` or unreadable text, the other three
+ by `isMediaHeld` (`isChannelHeldForLane`), and the pick→run marker backstop lets the digest lane through a
+ media move; the backfill batch and `normalizeAllLiveChat` keep the media guard. Fourteen kinds flip
+ `needsMedia` → `needsText` (the plan's list), and `runManagedFunction` asks the text guard for them, at
+ enqueue and at start. `channelWriters(slug, { mediaOnly })` keeps `kindNeedsMedia` jobs and the non-digest
+ lanes' units (no caller yet; T2's mover passes it).
+- **`onDrive` by file kind.** The snapshot reads the text directly; a video's tiered links are statted
+ together as one `onDrive(mediaDir)` call, only while the media is `ok`/`in-place`; a drive that does not
+ answer leaves `totalMediaBytes` and `totalAudioBytes` ABSENT and the snapshot is still written. Byte
+ fields: `totalMediaBytes` (tierable names), `totalTextBytes` (new), `totalClipsBytes` (no longer inside
+ media). `readChannelStat` and the recency tail reads pass a drive only for a legacy channel.
+- **umtool's twin** (`report-to-video/cues.mjs`) is now the twin of the TEXT guard: it refuses a legacy
+ channel, mounted or not, and a marker only when its `scope` is `tier-migration`; relocated media is read past.
+
+**Deviations from the plan** (one sentence each):
+1. `JobKindMeta.needsText` (+ `kindNeedsText`) is new: a kind flipped off `needsMedia` would otherwise run
+ unguarded on a legacy channel whose `data/` link dangles and read it as empty.
+2. The tier link carries the file's times (`lutimes`) and `normalizeLiveChat`/`isLiveChatCuesFresh` `lstat`
+ the raw replay: the raw is media now, and the index's freshness check would otherwise reach the media
+ drive per video.
+3. `normalizeLiveChat` tiers only when it wrote the cues (not on "fresh"). As first shipped this was
+ recorded as "an export build's normalize pass moves nothing", which was not true (`archiveLiveChat`
+ called it, so a build with stale cues tiered — and read — the raw); since the review `archiveLiveChat`
+ passes `tier: false`, so a build moves nothing. It still READS a stale raw replay through the link with
+ no channel guard (T2: treat the corpus-wide live-chat passes as media readers).
+4. `normalizeAllLiveChat` (corpus-wide, no slug for `runManagedFunction`) skips a channel whose media is not
+ reachable — the plan's "`normalize-live-chat` refused".
+5. `evictClipWindows` asks the text tier (`clips/` is never tiered) — its kind is in the flip list.
+6. The classifier's scratch also takes `*.part`, `*.ytdl` and the hook's own `.<name>.tierlink-<pid>`.
+7. `relocatedDataDir` stays exported (the retired shape) for the mover, the re-point, the rename and
+ `storageActions.ts` until T2 replaces it with `relocatedMediaDir`.
+8. `MediaLocationBadge.tsx` (T2's) gained the two `legacy` table entries the plan names (`Media layout
+ retired`), because its two `Record<ChannelMediaStatus, …>` tables fail tsc without them.
+9. The `isChannelHeldForLane` helper is new, so the lane decision is tested over real inspect answers.
+10. `markerHoldsText`: a scope-less marker whose target is the retired `<root>/<slug>/data` shape (the old
+ mover, until T2 writes `scope`) holds the text too, in the TS guard, the digest-lane backstop and the
+ cues twin — the plan's "refuse only `tier-migration`" would let a digest write into a `data/` the old
+ mover is copying.
+11. The hook writes nothing while a `.relocating.json` stands on the channel (the file stays real), a
+ backstop for a writer that started before a move.
+
+**Skipped until T2 rebases them** (28, each `{ skip: T1_SKIP }` with the reason string; they build the retired
+layout and expect it to read `ok`): `relocateChannelMedia.test.ts` 13 — "out: copies, links, records the
+target, keeps mtimes and reclaims the source", "abort from an onLog hook leaves the source intact, and the
+rerun completes", "back: restores a real directory, clears the config and reclaims the target", "out @ swap:

+refused", "out @ swap: a directory timestamp is settled …", "out @ swap: a file the target is missing is

+channel whose target is gone is auto-paused, …", "the drive coming back restores the tier it overwrote",
+"write: false reports the transition …", "a drive that blips for one pass is never paused", "the restore
+needs only one good pass", "one missed probe stalls the location; …", "the stall clears only after two clean
+probes in a row".
+
+**Re-premised (this slice's own guards, not skipped):** `channelMedia.test.ts` (the media link; 7 legacy /
+text cases), `buildIndex.test.ts` (the hold now comes from an unreadable text tier — the channel put on the
+retired layout with its drive away — plus case (j): an unmounted MEDIA drive does not hold the index; the
+write spy no longer counts a symlink's target as a written path), `buildStats.test.ts` ((i) likewise, (i2)
+new), `storageStall.test.ts` (a stalled media drive: counts, recency and the snapshot are read with no call on
+it; the legacy cases keep the old gates; M3 is now "a tiered file's stat never answers → the snapshot is
+written, its media bytes unknown"), `channelSnapshot.test.ts`, `evictClipWindows.test.ts`,
+`doctor.test.ts`, `run-operation.test.ts`, and umtool's `cues.test.mjs` (6 cases).
+
+**Open questions, answered.**
+1. **What `import-one` writes:** `importVideoAction` (`editor/app/channels/[slug]/pipelineActions.ts:465`)
+ runs `downloadOneManaged` for one URL — media, subtitles, metadata, the archive line, then the roster. A
+ media writer: it keeps `needsMedia`, and its media are tiered by `downloadOneManaged`'s hook.
+4. **Who hardcodes `<root>/<slug>/data`:** only the mover family — `relocatedDataDir` and its callers
+ (`relocateChannelMedia.ts`, `renameChannel.ts`, `storageLocations.ts`'s re-point, `storageActions.ts`'s
+ marker check), `deleteChannel`'s `<root>/<slug>` reclaim and `lib/storageLocations.ts`'s and
+ `savedVideoStore.ts`'s comments — all T2's; and `storageHealth.ts`'s `rootOfUnknownPath`, which now takes
+ both suffixes. Nothing in umtool, mcp, docker or `scripts/`. So `<root>/<slug>/media` beside
+ `<root>/<slug>/data` is as planned.
+
+**`isFile()` over a video dir, the census** (a dirent `isFile()` is false for a link): `channelSnapshot.ts`'s
+byte loop — rewritten (`lstat`, links statted through the watchdog); `channelSnapshot.ts`'s `dirFileBytes`,
+`evictClipWindows.ts:145` and `clipWindow-server.ts:49` — over `clips/`, never tiered, fine;
+`downloadOneManaged.ts:430` (`discardPrefetchDir`) — a tiered link keeps the directory, the safe direction;
+`relocateDir.ts:70` (`measureTree`) — keeps `isFile()` by the plan. **For T2:** `videos/[id]/page.tsx:67`
+(`loadVideoDir`) and `videos/page.tsx:61` hide a tiered link today — on a tiered channel the video page and the
+videos list would not show the audio until T2 lands.
+
+**Found and left.**
+- For T2: `views/storage.ts`'s "N of it is fetched clip windows" and `storageLocations.ts`'s
+ `mediaBytes`/`clipsBytes` rollups still treat clips as part of `totalMediaBytes`; `channelRow.ts` and
+ `freeUpSelection.ts` read `totalMediaBytes`, now the media tier alone. The old mover still records
+ `dataDir`, so a Move media on this branch alone produces a `legacy` channel.
+- For T3: the migration's links should carry each file's times (`lutimes`, as the hook does), or every
+ migrated live chat's cues read as stale and the next index build re-parses the raw from the media drive;
+ `buildIndex` re-parses a stale raw replay directly (no watchdog) and skips the track when it cannot.
+- `generateChannelSnapshot` passes a null config (a `config.json` with no valid `handling`) to the guard,
+ which then reads no relocation — as before this slice.
+- `removeVideoDirMedia` cannot clear `media/<id>/` while the media drive is unmounted (its `lstat` fails);
+ the video page's delete then leaves those bytes behind.

+
+#### Gates (logs `$T/T1-*.log`)
+
+- **tsc** (all workspaces) clean at every commit; last at `d56050ff`.
+- **common:** at `05275d86` **2,529 passed, 0 failed, 28 skipped** (2,557; `main`'s 2,528-test run had 49
+ failures on this branch's first pass, all re-premised or skipped as above). At `d56050ff` 2,530 passed,
+ 1 failed, 28 skipped: the failure is `storageHealth.test.ts`'s "M4: a healthy 64-wide walk … at half the
+ budget" timing case under a machine load of 22–28 (other sessions); the file passes 36/36 twice in
+ isolation right after. New tests: `mediaTier.test.ts` 35, `mediaTier-server.test.ts` 16,
+ `mediaTierHooks.test.ts` 4, `channelMedia.test.ts` 23 (rewritten), plus cases in `channelWriters`,
+ `autoRunner`, `streamCommand`, `jobKinds`, `buildIndex` (j), `buildStats` (i2), `storageStall`,
+ `channelSnapshot`, `evictClipWindows`, `storageHealth`.
+- **Editor unit:** 109/109. **test:scripts:** 304 passed, 2 skipped (306) — a first run had the two
+ `queue-lock.test.mjs` timing cases fail under load; the rerun is clean. **umtool `cues.test.mjs`:** 23
+ passed, 1 skipped (LIVE).
+- **Build:** the capped editor build (`systemd-run --scope -p MemoryMax=6G`, `next build`): exit 0, 172 s,
+ at `05275d86`.
+- **e2e** (from the worktree root, `$T/T1-specs.txt`: maybe-missing, video-page, cleanup-holds,
+ cleanup-actionable, auto-queue, digest, jobs-channel, channel-storage) at `05275d86`: **78 passed, 5
+ failed, 8.9 min** (after 33.6 min in the queue). The 5 are all `channel-storage.spec.ts`, all the retired
+ layout reading `legacy`, as expected until T2 rebases the mover: "relocate a channel's media to another
+ root, and move it back" (:80), "the /channels bulk move queues one job per channel and skips the rest"
+ (:250), "a bulk move puts every job on one queue and skips a channel with nothing to move" (:391), "the
+ Storage panel moves to a location picked by name" (:484), "Sync all skips a channel whose media drive is
+ not mounted" (:1091 — now says `media legacy: … run archilyzer storage migrate-tier test-youtube`). Not
+ re-run after `d56050ff` (unit-covered; a marker rule the specs do not reach).
+- **Privacy gate:** 0 added lines carry the user or host name (`git diff 7f4901f1`, counts only; the one
+ file the whole-file grep names is `plans/FACTS.md`, with the same count as on `main`). No identifier ending in the suffix the publish gate refuses.
+- **Numbers tool:** none.
+
+#### Review (SHIP AFTER FIXES, 12 findings) and the fixes
+
+Every commit over `main..HEAD` was rewritten (`git filter-branch --msg-filter`, worktree only) so its
+trailer is the session's `Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>` + `Claude-Session`
+line (finding 12): tip `f3f23792` → `001e9de7`; the shas in the table above are the rewritten ones
+(`828dc1a2` → `98ef1772` is the first `plans:` commit).
+
+| Finding | Fix |
+|---|---|
+| H1 the index stats (and may read) a tiered live chat through its link | `263c8b17`: the scan's `subsMs` loop `lstat`s a tierable track; a stale-cues fallback on a tiered raw reads through `onDrive(mediaDir)` only while the media is `ok`/`in-place`, else keeps the cues the last build held; `6b795c67`: an EXDEV tier gives the copy the file's times (`stat` and `lstat` agree). New gate `buildIndex.test.ts` (k): a STALLED media drive (the location marked, every call through a link onto it hanging) with a tiered live chat — the index and the stats build complete, nothing held, the live-chat cues kept, no call on the drive. A mutation (a following `stat` in `subsMs`) makes it hang. |
+| L2 crash window between the two renames | `6b795c67`: the bytes are placed by hard link (same disk) or atomic copy and renamed into the tier, then ONE rename swaps the name — it always resolves; `tierVideoDir` removes a dead process's stray `.tierlink-<pid>`. Tests: one inode after a same-disk tier; a stray healed. |
+| L3 `removeMediaFile` derefs only into `media/<sameId>/` | `6b795c67`: any id under the channel's own `media/` (never out of it); the target's dir is dropped when it empties. Test. |
+| L4 the export build tiers the raw live chat | `95c9a82c`: `normalizeLiveChat({ tier: false })` from `archiveLiveChat`; deviation 3 corrected above (the build still READS a stale raw — for T2). |
+| L5 a move that starts mid-hook (for T2) | `6b795c67`: the marker is asked again after the bytes land and before the name changes; the tier's copy is removed if one stands. |
+| L6 a video-dir delete on an unmounted or stalled media tier | `95c9a82c`: `deleteOneVideoDir` refuses unless the channel's media is `ok`/`in-place`, and removes the tier's side through `onDrive(mediaDir)`, refusing with the drive's sentence when it does not answer — before the text is touched. |
+| L7 gates at the tip | re-gated below. |
+| N8 an in-place `media/` takes a watchdog slot | `6b795c67`: a real `media/` is answered from the corpus disk. |
+| N9 `totalTextBytes` counts containers and partials | `95c9a82c`: documented as everything on the corpus disk but `clips/` and the tier. |
+| N10 a shard save runs the tier sweep | `95c9a82c`: skipped when `saveShardOnly`. |
+| L11 records | `001e9de7`: FACTS and the changelog bullet say what the index does with a tiered live chat; the bullet says "Needs a rebuild and restart of the editor." and names the refused video delete. |
+
+**Gates at `001e9de7`** (logs `$T/T1-regate2.log`, `$T/T1-e2e-2.log`): tsc clean; common **2,535 passed,
+0 failed, 28 skipped** (2,563); editor unit 109/109; test:scripts 304 passed, 2 skipped; umtool
+`cues.test.mjs` 23 passed, 1 skipped; capped editor build exit 0, 101 s; e2e (the same 8 specs) **78 passed,
+5 failed, 8.2 min** (after 39 min in the queue) — the same five `channel-storage.spec.ts` cases (:80, :250,
+:391, :484, :1091), the old mover's layout reading `legacy`, nothing else red. Privacy: 0 added lines carry
+the user or host name.
+
+**Re-review: SHIP**, with R1 and R2 folded in before the merge. R1 (`15acd7c7`): the index read a whole raw
+live chat under the watchdog's one-stat budget, and a timeout was never retried. Ruling: it probes the
+drive with one `stat` through `onDrive(mediaDir)` and then reads the raw directly, and a track that is
+neither read nor kept is stored with `subsMs: null`, so the next build retries it (case (l),
+mutation-checked). R2 (`ba24a313`): the classifier calls the hook's media-side temp
+(`.<name>.tiering-<pid>`) scratch, and `tierVideoDir` sweeps a dead process's temp from `media/<id>/` while
+the tier answers. Gates at `ba24a313`: `buildIndex.test.ts` + the tier tests 72/72; tsc clean; common 2,538 passed, 0 failed, 28 skipped (2,566).
+
+**Merge of `main` `173dd42b`** (D0 on U1, export 0.11.1, XP) at `ffbfbd63`: three conflicts, all appends —
+`channelWriters.test.ts` keeps both new tests (T1's `mediaOnly`, D0's ghost meta), `editor/CHANGELOG.md`
+keeps every `[Unreleased]` bullet (main's, then T1's), and this file keeps U1, XP, D0, then T1 under
+`## Record`; `channelSnapshot.ts` (D0's `mapInYieldingChunks` around T1's per-video body), `channelWriters.ts`
+and `buildIndex.ts` (XP's per-site posts predicate) merged cleanly. Re-gated on the merged tree
+(`$T/T1-regate4.log`, `$T/T1-e2e-3.log`): tsc clean; **common 2,573 passed, 0 failed, 28 skipped**
+(2,601); **editor unit 109/109**; **test:scripts 394 passed, 2 skipped** (two runs at a machine load of
+32–35 failed `queue-lock.test.mjs`'s timing cases, 1 then 2; that file passed 11/11 three times alone and
+the full suite was clean at load 10 — this branch does not touch `scripts/`); capped editor build exit 0,
+92 s; **e2e (the 8 specs) 78 passed, 5 failed, 8.2 min** — the same five `channel-storage.spec.ts` cases
+(:80, :250, :391, :484, :1091), the old mover's layout reading `legacy`, nothing else red.

The renderer awaits `document.fonts.ready` before its first seek, so every
frame sees the built timeline.
+**A backslash in a page's script is a template literal's first.** The page
+modules write their runtime script inside a JS template literal, where `\s`
+is not an escape and becomes a plain `s`: the popup's `replace(/\s+$/, "")`
+reached the page as `replace(/s+$/, "")` and stripped trailing letters s, not
+spaces, in the one case it runs (a clamped card whose paragraphs were dropped
+after one that fit exactly), so a quoted word lost its last letter. Both the
+popup's and the feed's pages write `\\s` in the module; read in the module a
+single backslash looks right, and only the composed page shows the wrong one,
+which is why `chrome-posts.test.mjs` reads the regex off a composed page.
+
+**Switching the posts layout moves the footage, so it is a rebuild, not a
+re-render.** The feed frames every footage segment into its own box when the
+segment is built; the popup frames into the deck's. `--chrome-only` lays
+chrome over the segments on disk, so over segments framed for the other
+layout it would draw the column over footage (or leave a gap where it
+expected some). Each framed segment's `<id>.cut.json` records `framing:
+{ layout, box }`, and `--chrome-only` / `--chrome-preview` refuse, by name,
+any segment whose box is not the cut's; a record-less segment was built for
+the deck's box. A normal build with `--skip-fetch` reframes from the cached
+windows.
+
+**The framing record does not cover `overCards`, and full-frame segments are
+never framed.** A card built under `overCards: "hide"` is full frame and
+writes no framing record; switch `overCards` to `"show"` and `framingProblems`
+reads the missing record as the deck's box, so `--chrome-only` lets it through
+and lays the deck (and the feed) over a card that fills the frame. The other
+way, a card framed under `"show"` is no longer checked once `"hide"` makes it
+full frame, and keeps its small box with nothing drawn around it. Either
+toggle needs a normal build. Separately, `scroll`, `chart` and `ledger`
+segments are never framed: with `overCards: "show"` the deck covers their
+bottom 190 px, and under the posts feed the 600 px column also covers their
+right third for the whole segment.
+
+**The build-trace check reads a template literal nested in another's `${}` as
+the end of the string.** `scripts/next-build-trace.test.mjs` scans each module
+for path and fs calls on `import.meta.url`-derived values. One
+`` `${a} (${ok ? `x ${b}` : `y`})` `` in build-video threw its string tracking
+out of step, and it then read the rest of the file as one call reaching the
+`import.meta.url` of the CLI guard: 69 false findings. Hoist the inner
+template to a const; nothing at run time changes.
+
+**A whole-cut overlay is laid like the deck's, whatever it draws.** The feed's
+column is a second full-length sequence; it takes the deck's `-reinit_filter
+0`, `format=rgba` and `shortest=1` (its frames mix RGB and RGBA like every
+HyperFrames sequence), not the posts windows' `-itsoffset` and

+
+The cut goes to black before the teaser and the teaser comes up out of it, like
+a trailer. Only a teaser takes a `dip` (anywhere else it is refused, and so is a
+dip on the first entry, which has nothing before it to fade).
+
+1. **The fade — the whole frame.** Over the previous segment's last `fade`
+ seconds, ending on its last frame (where the dissolve into the teaser ends),
+ everything on screen eases to black: the footage, the deck, the feed column,
+ popup posts, a rail. Its sound fades to silence over the same frames. The
+ picture is ffmpeg's `fade` out to black laid on the FINISHED picture, after
+ every overlay (`dipWindows`, `dipVideoFilter` in `build-video.mjs`), and
+ only inside the dip's window: every other frame passes untouched. A fade to
+ BLACK stays in the stream's yuv420p (luma 16, chroma 128) — only a coloured
+ fade goes through RGB, which is why the end fade is a `geq` — and it is
+ about 25× faster than the same blend in `geq` at 1080p (a preview window
+ that starts inside the fade uses the `geq` form). The sound is the end
+ fade's `afade` on that segment's join. Both are made where the cut is joined, so `--chrome-only` changes a
+ dip without re-encoding a clip.
+ The crossfade into the teaser does not dissolve: over the overlap the
+ outgoing segment plays untouched (`xfade=transition=custom:expr='A'`, and
+ `acrossfade` with `nofade` on both sides) and the teaser takes over at its
+ end, under the black. A dissolve there blended the footage with the
+ teaser's black lead and darkened it faster than the deck and the feed,
+ which only the dip fades — the panels were left lit over a darker picture.
+2. **The black.** The blend stays fully black from that last frame for
+ `black` seconds more — whole frames at the cut's fps: a `black` that falls
+ between frames is taken to the nearest one (0.45 at 30 fps is 14 frames,
+ 0.4667 s; `dipOf`), and one that is already whole frames (0.6 at 30 fps) is
+ used as given, so the joined cut's black, the teaser's frame count and the
+ page's rise all end on the same frame. Under it, the teaser's own first `transition + black`
+ seconds — its **lead** (`teaserLead`) — are black and silent but for the
+ riser, so the teaser takes over in black and nothing is held: the teaser
+ segment is simply longer by the lead (`teaserSeconds(entry, D)`), and the
+ schedule, the chapters and the pips count it as they count any segment's
+ length (the crossfade's overlap included, as everywhere). The deck and the feed are gone in an instant on the
+ faded segment's last frame (`dipHideAt`), under the black, instead of
+ sliding away over the dissolve.
+3. **The rise.** The card opens with the letterbox already closed and dark; a
+ black veil over the ground and the light leak (under the words) starts
+ lifting as the black ends, slowly, to 45 % by the first line's impact
+ 0.35 s later, then blooms away over 0.3 s (`DIP_RISE`), so the first hit is
+ the moment the light comes on. The first line's slam starts 0.15 s after
+ the black, not 0.55 s (there is no dissolve to land after), and every later
+ time follows it. Under the black, a **riser** (`DIP_RISER`, synthesised like
+ the hits): a sub climbing 30 → 55 Hz and a band-passed noise swell, rising
+ for up to a second into the first hit and released 40 ms after it, about
+ 6 dB under the hit.
+
+With a dip, `seconds` is the CARD's — from where the light comes up — and the
+segment is the lead plus it; left out, the card is what its beats need from
+there (0.4 s less than without a dip). The ferret finale at `beat: 1.05`: the
+card 6.8 s, the segment 7.7 s at `{0.9, 0.4}`, 7.9 s at `{1.2, 0.6}`, 8.3 s at
+`{1.6, 1}`. With `{1.2, 0.6}` after c20 (the cut's 0.5 s dissolve): c20 fades
+over its last 1.2 s to black on its last frame, black holds 0.6 s more, the
+veil starts lifting 1.1 s into the teaser and its first impact is 1.45 s in.
+
+The lead counts the cut's transition AS BUILT: a `--no-xfade` build composes a
+teaser whose lead is the black alone (`buildTeaserSegment` and compose-chrome
+take the build's transition; compose-chrome's CLI uses the manifest's). The
+teaser's record beside its segment (`<id>.teaser.json`) names that transition,
+and `verify-build.mjs` counts the teaser's frames at it (an older record
+without it: the schedule's, else 0 under `--no-xfade`, which umtool's driver
+passes on whenever the build had it, else the manifest's). A
+teaser without `dip` composes the page, the sound and the segment key it
+always did, and a cut without one writes every graph it did.

+width at the bottom; the column stands on it from the frame's top, so the two
+read as one L-shaped surface around the picture. Nothing pauses and nothing
+moves: no hold, no footage move, and the cut is as long as its segments.
+
+- **Geometry** (`feedGeometry`): the column is `posts.width` (600) wide, flush
+ with the `position` side's edge and the frame's top, down to the deck's top
+ edge — 600×890 at (1320, 0) at 1920×1080. The footage keeps the frame's
+ aspect and is as large as fits beside it with `posts.inset` (24) clear on
+ every side, centred: 1272×716 at (24, 87), 66 % of the frame's width against
+ the deck alone's 82 %. A feed whose footage would be under half the frame's
+ width is refused (`postsFitErrors`).
+- **Framing.** Every footage segment of a feed cut — clips, stills, cards with
+ `overCards: "show"` — is framed into that box when it is built
+ (`deckFraming(render, { feed: true })`), for the whole cut. A cut is a feed
+ (`feedOn`) when the deck is on, `posts.show`, `layout: "feed"`, and at least
+ one post is drawn on a clip of the cut's whole timeline (an `--only` rebuild
+ frames as the full build would). Each framed segment's `<id>.cut.json`
+ records `framing: { layout, box }`; a still's and a card's record holds only
+ that.
+- **Switching the layout reframes every segment**, so it takes a normal build
+ (with `--skip-fetch` it re-cuts from the cached windows). `--chrome-only` and
+ `--chrome-preview` read the records first and refuse segments framed for the
+ other layout, naming each one (`framingProblems`); a segment with no
+ framing record was built for the deck's box.
+- **When** (`postSchedule`): a post has one time, `in` — its clip's start
+ plus the transition (start + D): after the incoming dissolve, and D in on
+ the first clip too, which has none; a clip's next posts follow
+ `seconds` apart, or closer on a clip too short for that, so the last is in at
+ least that long before the clip leaves. Once in, a post stays. The schedule
+ says `layout: "feed"` and carries each post's `in` — only when there are
+ posts to draw, so a popup schedule and one without posts are byte-identical
+ to what they were. `postWindows` is empty for a feed.
+- **The column** (`chrome-feed.mjs`, one composition for the whole cut,
+ region-local at the column, transparent outside its panel): a header (the
+ platform and `@handle`, or "Posts" over several authors, a count, "posts as
+ the timeline reaches them"), then an empty state until the first post. Each
+ post TICKS IN at the top, newest first: the cards already in slide down by
+ its height over `push` while it enters from the column's outer edge, its
+ accent rim flares and settles to a lit rail, which goes out when the next
+ one arrives. A card pushed past the column's bottom fades out as it goes —
+ the oldest scroll out. Over a segment the deck hides for (a full-frame card,
+ the teaser) the column slides out of the frame's side with the deck and
+ back after (`deckChoreography`'s visibility). Cards are the popup's design
+ sized for the column: 24 px words on 33 px lines, `maxLines`, the post's
+ date (the handle and platform too when there is more than one author), a
+ `qrSize` QR in its own cell. The plan (`feedCues`) runs in the page on the
+ measured card heights, embedded by `embedFn`, like the popup's.
+- **Files:** `compose-chrome.mjs <manifest> --region feed` — project
+ `chrome/feed/`, frames `chrome/feed-frames/` and their `.key`, a window
+ `chrome/feed-from<s>[-frames]`, the preview `chrome/feed-preview/` (never
+ rendered); cached exactly as the deck's. The build renders it after the
+ deck, checks it is as many frames as the deck's, and lays it the deck's way
+ (`-reinit_filter 0`, `format=rgba`, `shortest=1`) in the crossfade concat,
+ the hard-cut `applyChrome` pass and `--chrome-preview`.
+- **`verify-build`** checks `chrome/feed-frames` holds the whole cut's frames
+ and that the schedule holds and moves nothing.

+// The posts FEED's composition (`posts.layout: "feed"`): one HyperFrames page
+// for the whole cut -- a column of posts beside the footage, standing on the
+// deck, so the two make an L around the picture.
+//
+// PURE, like chrome-deck.mjs and chrome-posts.mjs: a schedule and a render
+// block in, an HTML string out. compose-chrome.mjs copies the assets in beside
+// it, writes it and renders it; nothing here touches a file.
+//
+// ---------------------------------------------------------------------------
+// What the column does
+// ---------------------------------------------------------------------------
+// Before the first post it shows its header (who posted, on what) and an
+// empty state. Each post TICKS IN at its `in` (deck.mjs postSchedule: its
+// clip's start + D, the transition's length -- the first clip's too, which
+// has no dissolve into it; several on one clip a `posts.seconds` apart): it lands at the TOP, newest first, as a timeline
+// reads, and every card already in slides DOWN by its height. The newest
+// wears the highlight -- an accent flare that settles to a lit rail and rim --
+// until the next one takes it, then rests. A card that no longer fits the
+// column fades out as the stack pushes it past the bottom: the oldest scroll
+// out. Over a segment the deck hides for (a full-frame card, the teaser) the
+// whole column slides off the frame's side edge with it, and back after.
+//
+// The cut is never paused for it, and nothing moves the footage: the feed's
+// footage box is fixed for the whole cut (deck.mjs feedGeometry).
+//
+// ---------------------------------------------------------------------------
+// Why the stack is planned in the page, by a function that lives here
+// ---------------------------------------------------------------------------
+// How far a card pushes the others, and which ones fall out of the column,
+// depend on how tall each card is -- how its words wrap in the deck's own
+// face. So the page measures every card once the faces are in and hands the
+// heights to `feedCues`, THIS module's function written into the page under a
+// fixed name (`embedFn`, docs/quirks.md); the tests call the same function
+// with heights of their choosing. Every cue is a fromTo whose FROM is stated:
+// a render is a seek per frame, from parallel workers, in any order.
