Fourth commit of the Research + Loops arc. Completes the state machine
for research topics with the publish approval gate the spec asked for.
Migration 0032 — research_publish_approvals
Dedicated small table (id, workspace_id, topic_id, requested_by,
status, decided_by/at, created_at). Keeping it separate from the
existing `approvals` table (0001) because that one is tightly coupled
to gated tool calls inside an agent run — session_key + run_id +
action_type + category + payload + preview + requested_by_agent, all
NOT NULL. Forcing those nullable would ripple through cm_safety;
cleaner to give publish approvals their own two-transition state
machine.
New endpoints
POST /api/research/:id/submit-review processing → reviewing
(v1 caller-driven; the
orchestrator hook comes
when we wire actual runs)
POST /api/research/:id/request-publish creates a pending
approval. Rejects with
409 if the topic already
has one open.
GET /api/research/publish-approvals list workspace's pending
POST /api/research/publish-approvals/:id/approve flips approval to
approved + transitions
the topic
reviewing → publishing
(which stamps
published_at)
POST /api/research/publish-approvals/:id/reject stays in reviewing; new
requests allowed
The approve/reject write is an atomic UPDATE ... WHERE status = 'pending';
the decide() repo function returns whether the caller won the race so
concurrent double-approves collapse to a single topic transition.
