mimir-inbox

RETIRED 2026-10-13 (Prime 1530: albok subsumes library/note intake). docker compose down on corviduo-dev at 2123; the image, compose dir, config and the staging mount /mnt/muninn-staging/mimir-inbox are left in place for albok's unit 6 (backup, then teardown, albok-dev's). Bring-back = docker compose up -d in the compose dir, nothing else changed.

UI front end for large-document / novel / book ingestion into the Muninn KB — server-side FastAPI + HTMX over the muninn-gate API (#377). The submit path is: browser → mimir-inbox /upload (writes to staging) → path-addressed POST /jobs to the gate. Bytes never reach the gate; the gate references the staged file by absolute path, and the watcher opens it in place at claim.

Upstream: git@gitea.phasefinal.com:vh/mimir-inbox.git (infra-ops owns containerization — no Dockerfile upstream).
Host: corviduo-dev 10.250.50.152:8091, co-located with muninn-gate (:8090) and the worldtree-personal muninn watcher. Operator ruled co-location 2026-08-01 (reversing the earlier off-box/NFS plan); worldtree-dev approved the box placement.
Posture: LAN/WG-internal, no TLS, no public exposure (same as the gate). No datastore, no migrations, no writable path other than the staging root — a restart loses nothing.

Why co-located (not off-box/NFS)

The watcher opens the staged file in place at claim (core/muninn/runner.py), so staging's only hard constraint is path identity — the writer, gate, and watcher must resolve the same absolute string to the same bytes. Co-location on corviduo-dev buys that outright with one local filesystem and sidesteps the NFS failure modes (path-identity drift, TOCTOU widening, stale handles, a hung mount blocking the async staging check on mimir-inbox's event loop). Multi-host stays viable later behind a same-path shared mount, but co-location is the cheapest way to path identity.

Retention rule (load-bearing — INV-MI-19)

Because the watcher opens the file in place, a staged file must persist from submit until the job is terminal (complete, or failed-and-not-retried) — retry re-runs the structure phase, which re-opens the same staged path. Deleting on 201-submit would kill every retried job at claim with a not_found that looks exactly like a namespace mismatch. MIMIR_INBOX_STAGING_RETENTION_DAYS is the retry window, not a tidiness knob; do not tune it down without telling mimir-dev.

Config

All runtime config is environment variables — no config file. The real values (including the bearer-key secret) live in a gitignored .env next to compose.yaml on the server (0600); the repo carries .env.example. Two DEV-ONLY drift-guard vars (WORLDTREE_CONFIG_PATH, MUNINN_GATE_REPO) must not be set in the container.

Deploy

# 1. Fetch the source at the pinned tag/HEAD onto corviduo-dev, build the image
#    (all deps public PyPI; uv sync --no-dev is load-bearing — see Dockerfile):
docker build -t mimir-inbox:0.0.1 .

# 2. Provision the shared staging root (mimir-inbox-writable, gate+watcher :ro):
sudo install -d -o 1000 -g 1000 -m 0755 /mnt/muninn-staging/mimir-inbox

# 3. Drop the real .env (0600) next to compose.yaml with the bearer key filled
#    from the infra-ops key drop (~/.config/muninn-gate/mimir-inbox-env.sh).

# 4. Bring it up:
docker compose up -d

# 5. muninn-dev's one-file path-agreement probe, then the acceptance run.

Operational guard: docker fabricates a MISSING bind source as an empty dir that passes checks — confirm /mnt/muninn-staging/mimir-inbox exists on the host before up -d (step 2 does this). The container also fails boot if the staging root is not writable (os.access(W_OK)), so a perms miss surfaces loudly.

Health

GET /health-banner is the HTMX health surface (reflects gate reachability). The container healthcheck is a TCP-connect liveness probe only — it must not couple to the gate's state, so a gate outage never restarts mimir-inbox.
