The work-item spine: repository, validation, service and routes for Task, plus
its verdicts and append-only transition log.
Transitions are compare-and-swap. The expected current state is part of the
WHERE clause and the affected-row count is the answer, so two agents racing to
advance the same task cannot both win — a read-then-write would let both
"succeed" and silently lose one. Losing the race is a 409 naming the state the
task is actually in, not a 500, because on a shared board that is a normal
outcome the caller retries. Same idiom as InferenceTaskRepository's claim.
QA / Security / SRE are stages inside the task's own loop, not post-submit
reviewers, so each can bounce straight back to in_progress — that is what
"feedback" means here. A failed build likewise goes backward, not forward.
`merged` allows only `reopened`, so a merged task cannot be quietly edited;
post-merge failure is the one way back in.
The gate on `done` scales with risk instead of running a fixed pipeline:
trivial needs nothing, normal needs a passing QA verdict, high needs QA +
Security + SRE. Forcing a one-line docs fix through security review is how a
process gets routed around, so the cost has to match the risk. A FAILING
verdict does not clear a gate — a recorded failure is evidence the gate was
tried and did not hold. The 400 names which gates are still missing.
The human accept gate is a task-level yes/no on a resolved outcome, not
per-tool approval: accept fires the merge and stores the comment, reject sends
it back to in_progress and REQUIRES a comment, because the comment is the
direction the agent works from.
GET /tasks/:id returns `legalTransitions` so no client has to hardcode the table.
Tests: 25 service tests — full happy path, every stage's bounce-back, illegal
and no-op transitions, the CAS race (including that no event is written when
the race is lost), the complete risk matrix including failing-verdict-does-not-
count, and the accept/reject gate.
Local: build clean, workspace 2400 passed (+25), db 128 passed (same 4
pre-existing Secret failures), lint unchanged at 869.
