Exposes the durable queue (Stage 1+2) as a first-class API so callers
can enqueue work, get a task id immediately, and poll/stream/cancel
without holding open the original HTTP connection.
New endpoints (`/api/v1/inference-tasks`):
POST / → enqueue, return task id (201 + row).
failFast:false — task stays pending if no
worker is up; future bindSession drains.
Rejects 400 for public Llms (the existing
/llms/<name>/infer is the right tool there)
and 404 for missing Llms.
GET / → list owner's tasks. Optional ?status,
?poolName, ?agentId, ?limit query.
Owner-scoped at the route layer; cross-
user listing requires resource-wide grant.
GET /:id → poll one task. 404 (not 403) on a
foreign-owner id to prevent enumeration.
DELETE /:id → cancel a non-terminal task. Already-
terminal rows return 200 + current shape
(no-op). 404 on foreign owner.
GET /:id/stream → SSE feed of `chunk` and `terminal` events.
Re-fetches the row at subscribe time so
already-completed tasks emit one terminal
event and close immediately.
RBAC:
- New `tasks` resource added to RBAC_RESOURCES + the URL→permission
map in main.ts. Default action mapping: GET=view, POST=create,
DELETE=delete. The route layer enforces owner-scoping ON TOP of
the hook (404 on foreign owner) — without this, anyone with
`view:tasks` could list/peek every user's queued work.
- Singular alias `task` and the multi-word `inference-task` /
`inference-tasks` all normalize to `tasks` so users can write
`mcpctl create rbac-binding --resource task --role view ...` or
any of the variants and have it map correctly.
Tests: 9 new route tests covering the wire shapes, owner scoping
(matching/foreign), public-Llm rejection, missing-Llm 404, list
filter, and cancel semantics (pending→cancelled, terminal→no-op).
mcpd 893/893 (was 884, +9). Live smoke: POST against a public Llm
returns the documented 400, POST against missing returns 404, GET
list returns [] cleanly.
Stage 4 (next): CLI surface (`mcpctl get tasks`, `--async` flag on
chat-llm), GC ticker, smoke test (enqueue → connect worker →
drain), docs.
