Evolve topology_runs into a durable-job table (migration 0009): status state machine (queued/running/completed/failed/cancelled), kind, input graph, per-step checkpoint, error, last_event_id, timestamps. comparison becomes nullable (the result blob, absent until completion). Back-compat: existing rows default to completed/compare. cm-db repo gains the durable-job ops: enqueue_run, claim_next_queued (CAS via FOR UPDATE SKIP LOCKED), checkpoint, complete, fail, requeue_stale (resume sweep), and status(). Regenerated .sqlx cache. Also fix two pre-existing test RuntimeConfig literals missing the providers field (from the registry work). Co-Authored-By: Claude Opus 4.8 <[email protected]>

-- Evolve topology_runs from a write-once result store into a DURABLE JOB table.
|
|
-- A topology run becomes a first-class job with a lifecycle (queued -> running ->
|
|
-- completed/failed/cancelled), a checkpoint of completed-step outputs (for
|
|
-- crash-resumable long-horizon execution), and an event-journal offset. This
|
|
-- reuses the agent-run lifecycle pattern (RunState + checkpoint CAS + run_events
|
|
-- journal) without coupling to the chat-session FK that agent_runs requires.
|
|
--
|
|
-- Back-compat: existing rows are finished "compare" results, so the new columns
|
|
-- default to status='completed', kind='compare'. The result blob keeps living in
|
|
-- `comparison`, which becomes nullable (a queued/running run has no result yet).
