2026-08-17jobs: only settle may close; e2e proof harnesst
close_all no longer joins pump threads from the owner thread: job:close() joins the pump, and a pump parked in an owner-posted tool batch needs the owner back in the loop, so a synchronous close at turn_end could deadlock. close_all now cancels everything, closes only already-settled jobs, and defers the rest to their own settle; jobs.active() ignores closing children so the next turn can resume the id. e2e/ reconstructs the end-to-end proof against the real binary in print mode: a scripted fixture protocol plays primary and children, and the suite asserts the product surface from process output and JSONL bytes on disk — parallel batch with unknown-agent error, lane identity, tool inheritance minus subagents.*, resume with manifest re-identification, workflow diamond, sandbox fan-out with an ephemeral structured worker, catalog round-trip, child-store isolation from the session picker. mise run e2e; check stays independent.
2026-08-17subagents extension on the generic host surfacest
The rock now owns all subagent policy on top of libpanto-lua's generic APIs: children are ordinary panto.agent instances over rock-constructed stores, started with agent:run_async and awaited by arming uv.new_poll on each job's wake_fd from the tool handler's coroutine. subagents/jobs.lua carries the session policy the host used to own: the concurrency gate (4 running, FIFO queue, cancel-while-queued never starts), the await contract (results in input order; "first" returns settled plus remaining by identity), and settle-time shaping. subagents/spawn.lua seeds new children (primary system context, child role, profile body with manifest metadata), resolves model/reasoning through panto.ext.resolve_model, filters subagents.* out of the inherited tool set via agent:set_tools, and reads resume defaults back from stored message metadata. One-shot structured workers are a null_store agent with a declaration-only output tool, tool_choice forced, dispatch_tools=false. subagents/progress.lua renders per-tool-entry cards through the component handle's invalidate seam; turn_interrupt cancels live children, turn_end closes them. Spec suite rewritten against fakes of the new surfaces (98 cases), including gate/queue/cancel bounds, resume-default extraction, one-shot capture via unresolved tool calls, tool filtering, and manifest seeding.
