M3 made MOSAIC_IMAGE_TAG required in compose, but run-task.sh never
called load_release — direct task runs failed in compose before any
model call. release.sh paths masked it by exporting the tag to children.
Found by owner-run test-task.sh; failure receipts were in the run
records' stderr.txt.
Closes#14
- scripts/mosaic-task.mjs: validate | run | list
- Strict v1 schemas: unknown keys rejected; ids/prompt/expectExact/
timeoutSeconds bounds enforced; optional mission file resolved against
the task file and validated too
- run: executes through the config-driven container path with stdin
detached (issue #5 class), SIGKILL timeout (default 120s), trimmed
response capture
- Immutable run records under <dataRoot>/runs/r-<utcstamp>-<rand>/:
task.json + mission.json snapshots (write-once), stderr.txt, result.json
- expectExact gate: mismatch -> status failed, exit 1; result.json is
always written
- scripts/run-task.sh: load_config + bootstrap_runtime_dir before exec
- M2 scope: mission directives are snapshotted for provenance, not yet
injected into the runtime prompt (later policy layer)
Closes#6, closes#7
