In `@packages/nooa-cli/src/nooa_cli/tools/repo_tools.py`:
- Around line 545-546: Update the docstrings for the anchor-returning methods,
including the one near `_anchors_editable` and the method near line 607, to
state that only anchors marked `editable=True` support `self.shell.replace` and
that anchors from non-host sessions are read-only. Remove the unconditional
claim that anchors are editable whether or not a session is wired.
- Around line 1032-1041: Update the tree-sitter guard in the reference-search
flow to use self._anchors_editable instead of excluding all sessions, preserving
the heuristic fallback for sessions that do not share the host filesystem.
In `@src/nooa/runtime/channels.py`:
- Around line 861-864: Update the running-handle cancellation in
`remove_channel()` to skip completed tasks and set `_cancel_called` before
cancelling an active task. This lets the existing repeat-cancellation guard
protect cleanup when shutdown or another cancellation reaches the same handle.
In `@src/nooa/storage/sqlite.py`:
- Around line 674-702: Update _SessionClaim to record the owner’s PID-namespace
and boot identity with its PID, then have claim_owner_is_confirmed_dead return
False if either identity is unavailable or differs before checking whether the
PID is gone. Keep this check diagnostic-only; do not use it to automatically
reclaim or reopen claims.
In `@src/nooa/tools/shell_tools.py`:
- Around line 793-797: Move the editable check in the Match branch ahead of the
ambiguity check for new, so read-only anchors always receive the session-only
error before any replacement guidance. Keep the existing errors and behavior for
editable matches unchanged.

Ported from #382 (acp/1-core-runtime-sessions) without its session-store changes. - QueueManager.shutdown(include_daemons=False) now leaves daemon channels running by default, so a host that tears down per-turn work does not also kill long-lived producers. CodingAgent.close() is the full teardown and passes include_daemons=True explicitly. - Repeat cancellation is skipped only while our own cancel request is still pending (_cancel_called and task.cancelling()), so a task that swallowed an earlier cancel can still be cancelled again. - remove_channel() marks _cancel_called before cancelling, matching the rule above. - Channel.flush(fire_on_get=) lets callers drain without firing get hooks. - Replacing a channel prunes the old channel's handles. - ContextVarStream falls back to the process stream when a background task writes to a capture buffer that has already been closed.

SessionResumed and SessionCleared are not specific to the TUI; any interactive host emits them. EventBase gains handler_aliases, and EventManager notifies subscribers of each alias too, so handlers still registered under "TuiSessionResumed"/"TuiSessionCleared" keep firing. The old Python names remain as aliases of the new classes. Ported from #382 unchanged. Signed-off-by: Paul Furgale <pfurgale@nvidia.com> Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…oxes Ported from #382 without the session-store layer. - is_sqlite_database_active() probes with a shared flock, so concurrent probes can no longer report a never-opened database as active or make a real opener fail. Lock acquisition retries briefly (_LOCK_ACQUIRE_RETRIES) instead of failing on a probe's transient hold. - The .active claim records the owner's PID-namespace and boot identity (_owner_identity()). claim_owner_is_confirmed_dead() trusts a dead PID only when that identity matches, so a PID recycled by a reboot or seen from another namespace is never mistaken for a dead owner. - SQLiteStorageManager(must_exist=True) opens with mode=rw and never creates a database that was deleted after it was listed. The claim tests that lived beside SessionStore on #382 are re-homed in tests/storage/test_session_claims.py and drive SQLiteStorageManager, is_sqlite_database_active and _claim_path directly, since SessionStore does not live in core. The identity test now skips when procfs identity is unavailable, before spawning anything, and uses sys.executable for the short-lived child instead of "true". Also adds snapshot regression tests from #382: a legacy TodoManager snapshot fixture and the PersistentVars inspection API.

…h them Match gains editable (default True, preserved by slicing and shown in repr). A Match anchored in another session's filesystem is created with editable=False, and ShellTools.replace() refuses it before the two-argument ambiguity check. The order matters: the ambiguity error advises switching to the path-string form, which has no editable guard and would write to the same-named host file. Ported from #382 unchanged.

Review agent note: I'm still getting my bearings here but I'm surprised that in a V1 we're talking about legacy stuff. I have questions about trying to maintain quote unquote legacy subscriber compatibility. I don't think we should try to be worry about legacy compatibility in a 1st release. (transcribed)

Part 1 of 4. Core-only fixes that the coding-agent/ACP work depends on. No session store, no
InteractiveAgent, no packaging changes beyond one deleted entry point. Targetsmain.Reader's guide
1. Queue/channel cancellation semantics —
src/nooa/runtime/channels.py(+event_manager.py,stream_wrappers.py)Why: the shared turn driver in PR 3 drives cancellation for every host through
QueueManager, and exercising it that hard surfaced three pre-existing races plus one safety default.shutdown(include_daemons=False)now sparesdaemon=Truehandles unless told otherwise. The rendered.shutdown()hint is model-visible, so the safe behaviour has to be the default. The one genuine final close (CodingAgent.close()) passesinclude_daemons=True— that is the sole line touched inpackages/nooa-cli/src/nooa_cli/coding/agent.py.JobHandle.cancel()is skipped only while our own request is still pending (_cancel_called and task.cancelling()); checkingcancelling()alone could skip the first request when the job body was itself inside anasyncio.timeout, and a flag alone ignored a job thatuncancel()ed and must accept a second request.remove_channel()sets the same flag so a later shutdown can't inject a secondCancelledErrorinto a handle's cleanup.Channel.flush(fire_on_get=True)lets a host's dequeue-side durability hook run for items discarded by a flush (a cancel racing a just-admitted prompt used to lose the prompt silently).src/nooa/runtime/tests/*,tests/runtime/test_channels_queue_ergonomics.py(readTestQueueManagerShutdownKeepDaemons,TestQueueManagerRemoveChannelPrunesFinishedHandles,TestJobHandleCancelIgnoresUnrelatedCancellingCount— each was verified to fail on the prior code),test_queue_status_cheat_sheet.py,test_stream_wrappers.py.2. Host-neutral session events —
src/nooa/events.py,src/nooa/context_blocks/events.pyWhy:
TuiSessionResumed/TuiSessionClearedare named after a host that is going away. Renamed toSessionResumed/SessionCleared;EventBase.handler_aliases(new, default empty) letsEventManagerkeep notifying subscribers registered under the old names.tests/test_event_auto_registration.py.3. Cross-process session claims —
src/nooa/storage/sqlite.pyWhy: two hosts/processes can now open the same on-disk session, so the
.activeclaim (what makes the secondopen()fail instead of corrupting) is exercised far harder than when one host existed. Testing it harder found it racy.flock; the exclusive probe collided with itself across processes (~16% false "active" under concurrent probing, measured).claim_owner_is_confirmed_dead()refuses to answer unless they match this process's own before trustingos.kill(pid, 0)— a bare PID can belong to an unrelated live process in another namespace. Conservative by construction: never a false "dead".SQLiteStorageManager(must_exist=True)opens withmode=rw, so a session deleted between a metadata read and the lock surfaces as missing instead of a silently recreated empty database.tests/storage/test_session_claims.py(new; the claim tests rewritten against the storage manager directly),tests/storage/test_legacy_todo_snapshot.py+ fixture,tests/storage/test_snapshot_vars.py,tests/test_sqlite_reconnect.py.4.
ShellTools.replace()on read-only anchors —src/nooa/tools/shell_tools.pyWhy:
Matchanchors can now come from a session filesystem the host can't write to (editable=False). Theeditablecheck runs before the two-argument ambiguity error, because that error's advice ("use the path-string form") has no editable guard and following it would write to a same-named host file.tests/tools/test_shell_tools_modern_behavior.py.Not in this PR (moved to PR 2/3)
