Append-only, newest last. One block per session or run. Not a changelog: this records what happened on the day a number was produced, so a later postmortem can find it.

2026-08-11 Audit second pass [no task]

Command: none. Source reading only. Outcome: finished. AUDIT.md grew from 565 to 771 lines with a ## Second-pass findings section: 4 new P0, 6 new P1, 13 P2, 5 additions to the Phase 1 list. Produced: commit 6d9df5b, AUDIT.md:566.

2026-08-11 Audit Phase 1 implemented [#203]

Command: python worker_scene.py worker_script.py worker_vision.py session_manager.py, pytest -q --ignore=test_api.py in the orchestrator. Outcome: finished. All self-checks pass, 108 orchestrator tests pass. No GPU work, no pipeline run. test_api.py was skipped because fastapi is not installed in the workpc venv. Produced: decisions/audit-phase1.md, caveats/audit-open.md, ROADMAP.md, and this scaffold.

One existing test asserted the bug: test_name_binding.test_conflict_flags_and_stays_unnamed relied on orphan flags leaking into every chapter, because it never created panel rows. It now creates them.

2026-08-11 Orchestrator half committed and deployed [no task]

Command: pytest -q --ignore=test_api.py, then docker compose up -d --build orchestrator on homesrv. Outcome: finished. 108 tests pass. Commits 1c60710 (orchestrator half) and 94bd4d8 (minio pin) in /mnt/server/home/kami/docker-apps. Orchestrator and minio both answer health on homesrv.

The rebuild recreated minio as a side effect and it crash-looped with exec format error: the compose pin was the arm64 manifest digest of minio/minio:latest and homesrv is amd64. Repinned to the amd64 digest. Nothing about Phase 1 caused this, but any compose action that recreates minio would have hit it, so it was latent, not new.

Still unrun against a real chapter.

2026-08-11 S3 viewer and storage swap, tasks #116/#117 [#116 #117]

Command: docker compose on homesrv, dig, openssl s_client. No pipeline, no GPU. Outcome: partial. Viewer works, storage swap staged and unfinished.

#117 needed no new software. stowage at ~/docker-apps/stowage was already configured against the manga MinIO and had been dead since 2026-07-19 with exec /sbin/tini: exec format error: its digest pin was the arm64 manifest. Repinned to amd64 sha256:91be7f13, chowned data/ to uid 65532 for the new image, and it serves. MinIO had the identical bug, repinned to sha256:a1a8bd4a. A sweep of all 470 local images on homesrv found exactly those two arm64; nothing else in the homelab is affected.

#116 is staged, not done. rustfs runs alongside MinIO on 127.0.0.1:9010/9011, pinned sha256:19b105cc, data at /mnt/hdd2/rustfs. Buckets are empty: the mc mirror of audio layers manga panels raw video (350M, all in manga) has NOT run. /mnt/hdd2/minio/data is untouched and is the rollback. RustFS is 1.0.0-beta.12, labeled build-type=prerelease. Cutover would give rustfs 9000/9001 and repoint MINIO_ENDPOINT=minio:9000 in the orchestrator plus stowage/config.yaml; transport.py:95 needs no change if rustfs takes 192.168.1.104:9000.

Side quest, unrelated to the pipeline: the shared 41-domain cert stopped renewing. Root cause was DNS, not nginx. Every *.kvmx.ru name pointed at a hard A record for 109.229.102.117 while the line had moved to 109.229.127.149; the Mercusys DDNS at kvmx-home.mercusysddns.com was correct the whole time but nothing in the zone referenced it. Fixed with CNAME * -> kvmx-home.mercusysddns.com at reg.ru. Certificate now issues.

Two measurement traps worth remembering. The ISP transparently intercepts ports 80 and 443 by Host/SNI, so curl from workpc to ANY address returns kvmx.ru content and proves nothing about external reachability; bare TCP connects also succeed against arbitrary addresses and then hang. Three wrong root causes came out of trusting those probes before checking them.

Also patched ~/scripts/migrate-kvmx-https.sh:54 on homesrv. need_stream_module used sudo -n nginx -V and sudo -n nginx -T; the NOPASSWD rule covers only nginx -t, so it reported "stream module is not loaded" whenever it meant "could not ask for a password". Both checks now run without sudo. bash -n passes and both conditions evaluate true.

2026-08-11 Per-artifact buckets, rustfs buckets, baseline chapter run [#116]

Command: mc mb on rustfs, docker compose up -d --build orchestrator, pytest -q --ignore=test_api.py, ./start_workers.sh, then /job/create + /stage/clear + /job/resume for chapter 7c944dd4-e972-42c7-ba60-9f6939548e80 of "Teto X Egen" as job 778297bc-e7ce-439d-91b5-8a027060d17f. Outcome: partial. Storage split landed and is proven by the run. The run itself was still in direct when the session ended. Produced: decisions/storage-layout.md, caveats/speaker-attribution.md, 109 orchestrator tests pass.

Artifacts now split one bucket per class instead of everything under manga (decisions/storage-layout.md#bucket-per-artifact). Both MinIO and rustfs hold all six buckets. The run put 79 pages in raw and 116 panel crops in panels, so the split works end to end.

Two containers on homesrv had been dead for two weeks and blocked the work. manga-fetch was exited, so /job/create failed with httpx.ConnectError; manga-web was exited, so manga.kvmx.ru had nothing behind it on port 8083. Both started with docker compose up -d. Neither is related to the storage change. Neither was caught by any check, because nothing watches these containers.

Stage timings, 116 panels: crop 85s, vision ~4min, identity ~1min, reconcile ~7min for 35 pairs, dialogue ~8min. Faster than the 2026-07-17 run at 75 panels. The webtoon crop that 500'd in July succeeded this time.

Quality cross-check against the panel images, the point of the run. Dialogue text extraction is accurate. Character detection is accurate. Speaker attribution is not: three of three sampled two-character panels attribute both speakers to the wrong person, always swapped (caveats/speaker-attribution.md#tail-is-not-geometry). 24 of 81 speech lines resolve to a named character, which is the Phase 1 headline metric at 30%, and the sample says that 30% is not trustworthy. 26 of 113 detected people got an identity, and 25 of those 26 went to one character that turns out to cover two different women.

The run then reached scene 116/116 and failed in script at 87/116, not on OOM: 28 beats were rejected by the script verifier as unsupported-proper-noun: ['Choi', 'Haeseon'] (caveats/speaker-attribution.md#multiword-name-verifier). No two-word cast name can pass that check.

2026-08-11 Speaker provenance and the multi-word cast name

Command: .venv/bin/python worker_vision.py, pytest -q --ignore=test_api.py in the orchestrator. Outcome: both pass, 110 orchestrator tests. Nothing deployed, no GPU work, no pipeline run. Produced: decisions/speaker-attribution.md, two caveats rewritten.

_annotate_speaker_methods stopped stamping tail on a model guess. With two or more characters present the guess is dropped to unknown at confidence 0.0. With one present it is kept as model_solo at 0.7, the same claim the solo backstop already makes (decisions/speaker-attribution.md#no-fake-tail). Grounded som_face and solo_prior rows are untouched. Nothing outside worker_vision.py reads the literal tail, checked across both repos.

verify_script now tokenizes each cast name into allowed, so Choi Haeseon passes as two tokens (decisions/speaker-attribution.md#multiword-cast-names). That is the 28 beats job 778297bc lost.

The remaining ['Blur'] beat is a true positive that still halts the whole chapter, now recorded as caveats/speaker-attribution.md#one-word-halts-chapter.

Neither fix is live. The orchestrator container is not rebuilt and the workers are not restarted.

2026-08-11 Rerun from dialogue: the honest speaker number is 9%

Command: /job/cancel, /stage/clear dialogue, ./start_workers.sh, /job/resume on job 778297bc-e7ce-439d-91b5-8a027060d17f, twice. docker compose up -d --build orchestrator three times. Outcome: dialogue 116/116. 112 orchestrator tests pass, worker_vision.py self-check passes.

The named-speaker share is 9%, 9 of 95 speech lines, down from a reported 30% that counted fake tails. Multi-character panels contribute 0 of 40 lines by design. Single-character panels give 9 of 55. All 9 binds are Choi Haeseon, the row that covers two different women.

Five defects, four of them found by measuring the run rather than by reading code.

1. The fake tail label, fixed before the run (decisions/speaker-attribution.md#no-fake-tail).
2. The multi-word cast name in the script verifier (decisions/speaker-attribution.md#multiword-cast-names).
3. /stage/clear dialogue deleted nothing and reported success. dialogue and direct write onto the per-panel vision blob and had no _STAGE_TABLES entry, so run_stage_dialogue saw "dialogue" in vision and would have skipped all 116 panels. The proof is the second clear: 116 dialogue blobs and 75 direct blobs stripped that the first had left. This is caveats/audit-open.md#dishonest-clearing firing exactly where it was filed.
4. gemma answers the speaker field with whatever the prompt showed, most often the character description, and every such answer became a free-form name that no registry entry matched. 28 of 51 sampled lines (decisions/speaker-attribution.md#prompt-label-answers). After the fix, 3 of 95.
5. All 7 som_face lines pointed at a mark whose face paired to no present character, so the highest-trust provenance sat on a line with no speaker. Same defect class as the fake tail.

Identity is now the binding constraint, not attribution. 26 of 113 detected people carry an identity, 23%, and 25 of the 26 are the one over-merged row. Even perfect balloon binding caps this chapter near 23% named. The person who does hold an identity is stored as Lim Seonho while a separate row is named Seonho with alias Lim Seonho, so either name matches two rows, raises ambiguous-speaker and binds nothing.

Two more defects surfaced after dialogue finished. All 7 som_face lines pointed at a mark whose face paired to no present character (decisions/speaker-attribution.md#unpaired-mark). Then script halted at 112/116 because the narrator wrote "...Hm?" for the source line "Uh... hum...?", and both verifier rules fired on that two-letter interjection (decisions/speaker-attribution.md#interjection-false-positive). After the fix, script passed 116/116, the first time this chapter has cleared the verifier. tts then ran for the first time.

The run then completed end to end for the first time: tts 116/116, layers 116/116, render 116/116, assemble 1/1, finished 2026-08-11T20:08:16Z. s3://video/ holds 49 clips and a 50MiB chapter.mp4, s3://audio/ 49 objects at 32MiB. The per-artifact bucket split is now proven for every class except layers (decisions/storage-layout.md#bucket-per-artifact).

Two honesty defects surfaced at the finish, both recorded rather than fixed. layers reported completed 116/116 with an empty bucket, and the completed job still carries error: "partial: 112/116 completed" from the failure three resumes earlier.

2026-08-12 — the video got watched

No pipeline ran. The user watched chapter.mp4 for the first time and read out 19 timestamped defects. That found more than the previous four sessions of measuring, because the recorded metrics were all measuring whether code ran rather than whether the result was right.

Two measurements came out of it. First, chapter.mp4 is video 436.39s over audio 363.67s, so the narration finishes 72.7s before the picture and the gap accumulates. The 49 clips are clean: every one is 25fps exactly, video and audio agree to 0.03s, and they sum to 363.6s. Assembly adds 72.7s of video and no audio. Second, this manga holds 19 character rows of which 3 carry a name, and Choi Haeseon holds 25 of the chapter's 26 identity assignments. That is why the video calls the colleague Choi, never names the MC, and flips gender.

The A/V bug was narrowed with a per-round probe over the 49 real clips. Round 0 of _assemble_batched is correct, losing only the xfade overlap per group. Round 1 turns 359s of video into 100s while the audio survives at 358.79s. The round-1 filtergraph is arithmetically correct, and re-running the same chain by hand over only the 6 encoded intermediates gives a correct 348.24s with no warnings. Round 1 differs by holding a 7th input: the leftover 49th clip, which _assemble_batched passes through un-encoded. That passthrough is a third path beside concat and xfade and is the prime suspect.

worker_render.py gained an FPS = 25 constant, fps normalization in the xfade branch to match the concat branch, a _stream_dur helper, and a self-check that compares video against audio rather than asserting the file is non-empty. The old check only asserted getsize(out) > 0, which is how a 20% sync failure shipped. Pinning -r FPS on the output encodes was tried and reverted: it collapsed the chapter to exactly 100.00s by dropping frames to force CFR, which the comment at the concat branch already warned about. None of it is committed and none of it fixes the chapter yet.

The fps inconsistency between the two branches is real but not proven to be the shipped cause. The scene graphs hold 356 cut against 6 fade_black, so the real run's final round most likely stayed on the concat branch where no mixing happens.

Panel 7, checked against the art

The same day, the user pulled up panel 7 and checked every detection by eye. It overturned the framing this file carried an hour earlier, and it overturned two theories I proposed before being corrected.

Panel 7c944dd4-e972-42c7-ba60-9f6939548e80_p007, a wide establishing shot of an office through a window, crop 900x1650. Vision emitted 6 characters. Zero of the two identity bindings are correct and the one character who matters is unbound. person_5, described as "yellow sweater", is Seonho in the foreground and got no identity. person_6 is the colleague, who has no name in the story, and was assigned Choi Haeseon at 0.9. person_2 is a background extra and was assigned Lim Seonho at 0.9. person_1 is a window frame with nobody in it. person_3 and person_4 are background extras.

Three defects stack, recorded as caveats/speaker-attribution.md#bbox-wrong-space, #no-anonymous-identity and #extras-as-cast. The bbox values are consumed as absolute pixels, and on this panel that puts all six boxes in the top third with two inside a speech balloon. Divided by 1000 four of the six fit tightly. Identity therefore embedded crops of balloon edges and window frames, which is how a 0.9 confidence lands on the wrong person. Blank crops embed alike, a plausible mechanism for one row absorbing 25 of 26 assignments.

Two claims I made and had to withdraw. First, that rescaling by 1000 makes the boxes correct: after scaling, person_1 still sits on an empty window frame and person_6 clips its subject, and the descriptions are unreliable anyway, since person_6 reads "white shirt" for a green dress. Second, that the constraint is 16 nameless rows needing names. The opposite is true. The pipeline mints names onto people who have none, and at least one nameless row is a real recurring person who should stay nameless.

The "26 of 113 detected people carry an identity" figure that framed the roadmap counted mostly background extras. It should not be quoted again.

2026-08-12, chapter assembly, root cause and fix

Reproduced the A/V collapse offline with 49 synthetic clips at ASSEMBLE_BATCH=8 and six fade_black boundaries. It came out worse than the shipped run: two round-0 groups of 8 fresh clips collapsed on their own, so the single-item passthrough theory from yesterday is dead (decisions/chapter-assembly.md#passthrough-innocent).

Bisected one collapsing group by truncating the chain stage by stage:

k=7 out= 52.52   correct
k=8 out= 52.52   the last xfade contributed nothing
    [v6][n7]xfade=duration=0.050:offset=52.500   <- [v6] is 52.52s long, 0.02s of margin

_xfade_chain took its durations from _audio_dur, which is format=duration, which is max(video, audio). Each clip's audio outlasts its video by about a frame, so the offset accumulator crept ahead of the picture. Once the creep passed the transition width, xfade emitted the transition and threw away the second input and every clip after it, at rc 0 with nothing on stderr.

Fix: offsets come from min(_stream_dur(v), _stream_dur(a)), every input is floored to a whole frame count and trim/atrimed on both streams, and _check_assembled now verifies each encode against the predicted timeline instead of trusting the exit code (decisions/chapter-assembly.md#offsets-from-min-stream, #check-assembled).

Verified on the 49 real clips of chapter 7c944dd4, re-downloaded from MinIO:

before  r1 n=7 XFADE  in v=359.29 a=359.60 -> out v= 99.96 a=358.79
after   r1 n=7 XFADE  in v=359.61 a=359.62 -> out v=358.76 a=358.76
chapter v=358.76 a=358.76 gap=+0.00        (shipped: v=436.39 a=363.67 gap=+72.72)

worker_render.py __main__ passes. Two checks were added there, because the existing 4-clip A/V assert passed all the way through the broken build. One asserts the frame-exact trim on both streams, one assembles three clips whose audio outlasts their video by 0.4s. Mutation-tested by putting _audio_dur back: the new check fires with video=1.80 audio=3.56 expected=3.56.

Not done: s3://video/.../chapter.mp4 is still the broken 436s file. Rebuilding it means clearing the assemble stage and resuming, which is CPU-only and was not run.

2026-08-12, the chapter rebuilt, and the bbox space settled

The rebuild came out byte-identical to the broken file. Clearing assemble and resuming produced video 436.392031s over audio 363.674667s and nb_frames 9902 again, which proved the xfade fix committed earlier today never runs for this chapter. With all-cut transitions assemble takes the else branch, a concat demuxer with -c copy.

Reproduced that path offline in seconds and got the shipped numbers exactly. The cause is mixed frame rates: 14 of the 49 clips are r_frame_rate=30/1 at time_base=1/15360, the other 35 are 25/1 at 1/12800. -c copy writes the output in the first input's timebase, so those 14 play 15360/12800 = 1.2 too long with their audio untouched. collage_cmd hardcoded -r 30, which yesterday's FPS sweep missed. decisions/chapter-assembly.md#mixed-rate-stream-copy.

Fixed collage_cmd to emit -r FPS, and made assemble probe r_frame_rate across the clips and route mixed rates through the re-encoding tree. Rebuilt:

before  v=436.392  a=363.675  nb_frames=9902  avg_frame_rate=22.69
after   v=364.120  a=364.122  nb_frames=9101  r=25/1

The 14 clips in the bucket are still 30fps. Assembly normalizes them, so the chapter is correct without re-rendering, but the fast stream-copy path stays disabled for this chapter until render re-runs.

The bbox space is 0-1000, not pixels. Pulled all 113 detections from /review/identity and measured: 47 boxes have x2 past the 900px panel width, none has y2 past 1000 on panels 1257 to 2307px tall, 21 clamp at exactly 1000 in x, and the whole range is [0, 1000]. /vision now converts to pixels before returning, so identity crops, gated face pairing, the set-of-mark boxes and the review UI all read pixels (decisions/identity-bbox.md#bbox-is-normalized).

Checked by eye the way the user did. Drew the converted boxes on panel 7: five of six land on their subject, including person_5, who is Seonho in the foreground with headphones and carried no identity. person_1 still frames an empty window mullion, which is the extra-versus-cast caveat, not this one.

Not done: vision and identity have not re-run, so every box, embedding and ref_image_uris in the registry is still from the wrong space. That rerun is GPU work and was not started.
