The command queue is at-most-one-in-flight, but nothing ever expired a stuck command. When an agent claimed a command (RUNNING) then died before reporting a result - killed, uninstalled, or offline mid-flight - the row stayed in-flight forever and every operator action for that endpoint returned 409 'already in flight'. Reap in-flight rows past a staleness ceiling (15m for RUNNING, 60m for PENDING) to a new STATUS_EXPIRED at enqueue time, inside the same transaction, so the queue self-heals lazily the next time someone queues work. No background job and no schema migration - status is free-text.
The endpoint agent already reports an installed-software list (SBOM), but ingress dropped it: the collector schema had no entry for it and there was nowhere to store it, so operators could not see what is installed on a PC.
Persist it as a per-asset snapshot in a new endpointapplications table, replaced on every report (current inventory is what operators ask for, not install history). Add applications to the collector schema and KNOWN_PAYLOAD_KEYS so ingress stops discarding it, a read route for the raw collection, and a collapsed-by-default Installed software panel to surface it. appid is nullable groundwork for a future Managed Applications link; no matcher is wired yet.
Default fuzzy reconcile threshold to 0 and refuse merges when digit runs differ so numbered labels like Bay 311 never bind to Bay 310. Keep edit forms from clearing saved model fields when category filtering hides untyped rows. Includes in-progress computers policy and endpoints command feature work.
Migration tests knew no endpoints head revision, so the parametrized guards raised KeyError. Register it in EXPECTED_HEAD_REVISION.
EndpointState declared lastreportedat both index=True and an explicit db.Index over the same column, and the baseline migration named single-column indexes differently from what create_all builds. On a pre-existing table the name-keyed guard could not see the create_all index and added a duplicate, tripping the idempotency guard. Drop the redundant declaration and rename migration indexes to ix_<table>_<column> to match.
endpoints was absent from the universal site profile, so the installer would not offer it and prune-schema would drop its tables at provisioning. Add it.
The agent design record lived under docs/, which is stripped to the public wiki and normally absent from the tree; a lone file there un-skipped the wiki-publish guards. Move it into the plugin.
Server-side RMM telemetry plugin: current-snapshot endpointstates plus append-only curated endpointevents, resolved to existing Computer assets by hostname. Adds ADR-010 asset panels (status, services, recent events), dashboard quiet and stability cards, and a minimal Fleet list view that links into existing PC detail pages. Registers the activity sidebar icon and a dev-only sample seeder. Ingest arrives on the generic collector route; the future C# agent design record lives in docs/DESIGN-DECISIONS-agent.md.
