* fix(orchestration): serve a /clear'd structured worker through the session running it A structured (native chat) worker the user /clear'd keeps working in a successor session, but orchestration kept acting on the session it was started with, which the clear had closed. Terminal read and @idle status lost the handle, worker-read and the release archive served the pre-clear transcript, worker-show reported the worker exited, worker-stop closed the already-closed session and left the successor running, mail and Dispatch nudges were refused, and the idle sweep could put the successor to rest while its Dispatch was open. One forward walk over the durable session records now answers which session runs a worker's conversation. Worker authority and custody are judged on that session, so every caller holding a worker handle gets it by default; reads, archive, observation, status, group addressing and the incarnation liveness probe use it too. Stop closes the running session and re-resolves, so a clear that commits while the close waits is followed to its successor. The reverse direction (a successor's child env, user takeover, the idle sweep) maps a session to its worker through the lineage root. A successor's idle edge re-derives the worker's Dispatch mailbox, and settlement forgets parked mail on every session of the lineage, derived rather than stored. When the running session cannot be found (host not installed, a successor with no record, a looping chain) observation answers unverifiable, never exited; readers refuse with session_caller_not_live and stop closes nothing. worker-read and the archive warn that earlier conversation from before a /clear is not included. * fix(orchestration): close the review gaps in serving a /clear'd structured worker Review of the first change found places where a /clear'd worker still went wrong, plus a type gap that let the original bug shape compile: - worker-stop refused a structured worker whose old session read exited mid-clear (stopped, but the successor not yet committed); it now goes to the clear-aware stop once identity and ownership are proven. The terminal (PTY) gate is unchanged. - A worker stopped while its /clear successor had never run could never be released: no close writes death evidence for an agent that never started, so the probe read unverifiable forever. A released session that never started anything and whose chat is gone now reads exited; it stays unverifiable while the chat is listed. - worker-read, terminal read and the release archive now read the worker's whole lineage, oldest session first, under the same page limit and byte bound, instead of only the running session. This replaces the "earlier conversation is not included" warning. Cursors key later sessions' items by session, so a cursor taken before a clear stays valid and continues into the successor. - Pointer delivery re-derives a mailbox's target when an attempt ends; if a /clear moved it meanwhile, it delivers once to the new session. - Custody and status reads take the resolved running session, and one typed hold (held, not held, unverifiable) replaces the rebuilt authority in terminal read, worker-show and group addressing. - Smaller fixes: stop keeps an earlier close on its receipt; abandoning a side task no longer forgets the worker's parked mail; a release whose lineage cannot be verified ends release_unknown instead of staying requested forever; mail reach reports an unverifiable lineage as unverifiable, not ended; party resolution scans records once. A /clear typed into a worker's chat is reported as a user takeover, the same as any other message the user types there; a test pins it. * fix(orchestration): tighten the never-ran rule and the follow-ups to /clear handling Round-2 review of the /clear'd structured worker fixes found that the new rule for "a session no agent ever ran is exited" was too loose, and two of the new follow-ups missed a case: - The rule now requires the founding fence, which every reservation moves. A reservation that a restart released without proof, or a failed first start whose exit was never proven, stays unverifiable instead of reading exited. It no longer asks whether the conversation is open (any history read opens it, which stranded a stop, read, release sequence), and it treats only an authoritative tab index without the chat as retired. - Pointer delivery follows a mailbox a /clear moved on a thrown attempt too, keeping the attempt's own failure, and tries each session once. - Releasing a retired worker whose newest session cannot be read keeps the readable earlier sessions' output and says the latest one was lost, instead of freezing an empty archive. - worker-show judges status and addressability on one lineage walk. - The worker-stop comment says plainly that any structured worker that reads exited (a crashed agent too) is closed and its chat hidden; tests cover that and a takeover reported by the successor session. * fix(orchestration): keep a retired worker's earliest readable output across several lost sessions Releasing a worker whose chat was retired and whose newest session could not be read kept the earlier sessions' output only when exactly one later session was lost; after two clears with both later journals gone, release still froze an empty archive although the first session held the worker's answer. The archive now walks back past every unreadable later session, under the same page limit, and its warning says how many later sessions could not be preserved. The rule that reads a never-started session as exited also requires that the record carries no fence floor: a copy restored from backup may hide a reservation that the backup lost, so it stays unverifiable. * test(orchestration): build the takeover test's session record from the shared fixture The changed-code quality gate rejected the test's `as unknown as AgentSessionRecord` stub, which this branch had touched. It now builds a real record with agentSessionRecordFixture and a typed lease, so no type assertion is needed. * test(orchestration): give the cleared-worker pointer harness the sender-name dependency main added
