Found by the .228 lifecycle gate (2026-07-08, first quadlet-mode run):
stop→start on the legacy `mempool` umbrella app id destroyed the mempool
deployment. Under quadlet, package.stop removes the containers; package.start
then failed with `unknown app_id: mempool` because load_manifests drops the
umbrella manifest whenever the three split-stack members are loaded — leaving
nothing to recreate from and the stack down.
Two fixes:
- prod_orchestrator start/stop/restart now resolve the historical
`mempool`/`mempool-web` id to the split members (archy-mempool-db,
mempool-api, archy-mempool-web) whenever the umbrella manifest was dropped —
the same alias install already implements ("installing mempool assembles the
split stack"). Restart falls back to start for members whose container/unit
is gone. Legacy umbrella-only nodes are unaffected (alias inactive while the
umbrella manifest is live).
- is_missing_container_error (3 sites) now recognizes podman 5.x's
`no such object` inspect phrasing, so a genuinely absent container is
classified as missing instead of surfacing as a hard inspect error.
Tests: 2 new alias tests + 2 classifier tests; prod_orchestrator suite 61/61
green.
