Split artifacts across per-class buckets, record the baseline run

Panels, wavs, layers, clips, and the chapter mp4 leave the `manga` bucket for
`panels`, `audio`, `layers`, and `video`. The key under the bucket is unchanged,
so every reader that derives the bucket from the first path segment keeps
working. The orchestrator half moves in the same commit, per invariant 7.

The 2026-08-11 chapter run proves the split for `raw` and `panels` and produced
the first quality read on speaker attribution, which is wrong in every sampled
multi-character panel.

+## 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.
