Do not restate a finding here. Point at the decision.

The goal

This is the workpc compute half of a manga to narrated-video pipeline. It holds stateless GPU and CPU workers only. State, job scheduling, and stage orchestration live in a separate homesrv orchestrator repo (/mnt/server/home/kami/docker-apps/manga-infra/orchestrator/). The two talk over a fixed HTTP contract. The hard part is that one GPU serves every model, so the schedule, not the model, sets the wall time.

Machine split: workers run on workpc (RX 7900 GRE, ROCm). MinIO and the orchestrator run on homesrv (192.168.1.104, CPU-only). /mnt/server/home/kami/ is an SSHFS mount of homesrv.

Invariants

1. No durable state in a worker. No sqlite, no cross-request memory. A worker pulls inputs from MinIO by URI, does one stage, pushes outputs back, returns URIs. A /dev/shm cache is allowed because it may be dropped at any time.
2. One warm model at a time. Every GPU stage takes a lease from session_manager.py on 8095. A 409 is a queue signal, never a stale lease (decisions/audit-phase1.md#no-lease-stealing).
3. Never hold _lock across a model load or a health wait in session_manager.py (decisions/audit-phase1.md#unlocked-model-load).
4. A dialogue row's speaker is speaker_ref. The flat speaker field is a compatibility value and holds a character_id, not a panel-local id (decisions/audit-phase1.md#speaker-ref-is-canonical).
5. A stage never raises after setting awaiting_review. The pipeline's catch-all overwrites it with failed (decisions/audit-phase1.md#flag-resolution).
6. Never mint a character from an unparseable or out-of-range model answer. That is unresolved (decisions/audit-phase1.md#hallucinated-index).
7. The HTTP contract with the orchestrator is load-bearing. Changing a worker's request or response shape means reconciling the orchestrator in the same session. Neither repo's self-checks can catch a contract break, because each asserts its own side.
8. ponytail: comments mark deliberate simplifications and name the upgrade path. Respect them.
9. Nothing that positions an ffmpeg filter may use format=duration. It reports max(video, audio). It hides A/V drift, and it walks xfade offsets past the end of their input. ffmpeg then discards clips and still exits 0 (decisions/chapter-assembly.md#offsets-from-min-stream).

Working rules

./start_workers.sh              # dev: session_manager + 9 workers, each a uvicorn in a tmux window
tmux attach -t manga-workers    # per-worker logs
sudo systemd/install.sh         # production: one systemd unit per process (User=kami)

.venv/bin/python worker_scene.py    # every module has an assert-based __main__ self-check
.venv/bin/python test_vision_parse.py

cd /mnt/server/home/kami/docker-apps/manga-infra/orchestrator && pytest -q --ignore=test_api.py

There is no lint or build step. .venv is the ROCm torch env. Workers import transport by module name. Ports: crop 8000, vision 8002, identity 8003, scene 8004, script 8005, tts 8006, layers 8007, render 8008, session_manager 8095.

• Any non-trivial logic gets ONE runnable check in __main__, assert-based, no framework. Run the file to verify it.
• Editing a worker's request or response shape means editing the orchestrator too, in the same session.
• Update NEXT.md alongside any change that moves the plan, and append to JOURNAL.md after a run.
• Do not run GPU work or a full pipeline without asking.
