…repo tools Part 1 of 3 splitting the ACP shared-agent work (PR #330) into reviewable pieces. This part is the foundation with no CLI runner or ACP dependency: - nooa.sessions: SessionStore/SessionHandle/SessionRuntime move from nooa_cli.sessions and nooa_acp._runtime into core; the nooa_cli.sessions modules become re-export shims so existing importers keep working. SessionInfo.origin is renamed to host; create() accepts origin as an alias until nooa_acp moves over (removed in part 3). - storage/sqlite: cross-process session claims with a shared-lock liveness probe (no self-collision between probes), lock-acquire retries, and detection of provably-dead claim owners. - runtime/channels: daemon-aware shutdown, flush that can surface discarded items, repeat-cancel rule (skip only while our own request is pending), handle pruning on channel replacement. - events: SessionResumed/SessionCleared replace the Tui* names, with handler_aliases on EventBase for old subscribers. - interactive: PersistentVars is the single self.v implementation. - repo/shell tools: anchors stay editable with a real BashSession; session path handling.

Merge Risk: 🟡 Moderate · up to Most earlier issues are fixed, including the MCP approval scope, symlink-safe instruction reads, and project-only settings writes. Several issues remain before merge. A turn cancelled by the runner can surface as an unexpected cancellation to the host. Saving an MCP server can write a secret embedded in its URL or args into the shared project settings file. Forgetting a server can break later MCP save or forget commands. Some skill-command argument and help-text edge cases are also still open.

Preserve the delegate report when Todo merging fails.
QueueManager.spawn() wakes the controller with a JobError, but _delegation_report() only publishes the {objective, report} dictionary after delegate() returns. A Todo merge failure can therefore discard a worker report that was already produced. Include the objective, report, and error in the failure notification.

Cut the label at a sentence boundary, not at the first dot.
compact.partition(".") cuts at every ., including dots inside file names and versions. For example, "Inspect src/nooa/agent.py for races" produces the label "Inspect src/nooa/agent.". Hosts show this wrong label for common objectives that name files. Split only when whitespace or the end of the string follows the dot.

Register the file-based agent module in sys.modules before you execute it.
At Lines 118-122, module_from_spec() and exec_module() run, but the code never adds the module to sys.modules. The module's __module__ name is _nooa_custom_agent, and nothing registers that name.
Some code looks up sys.modules[cls.__module__] to resolve string annotations. Two examples:
dataclasses, when the custom file usesfrom __future__ import annotations. It raisesAttributeErroronNone.typing.get_type_hints(). It resolves with an empty global namespace and raisesNameError.
A custom agent file that uses postponed annotations can therefore fail at class definition or during hint resolution. The standard importlib recipe registers the module first and removes it if execution fails.

Path Traversal
Exploitability: Difficult
CWE: CWE-367 — Time-of-check Time-of-use (TOCTOU) Race Condition
Re-check the boundary after resolving the AGENTS.md symlink in the reader.
discover_agent_instruction_files checks the symlink target against resolved_boundary at Line 61. _read_instruction_file calls path.resolve() again at Line 88 and does not repeat that check. If the symlink is retargeted between discovery and read, the reader opens the new target. The new target can be outside the repository. Its content then goes into the agent context.
The no-follow walk only covers the path that resolve() returns. It does not enforce the repository boundary. The docstring says the walk gives every-segment protection, but that is only true after this second resolution.
Pass the boundary into the reader. Check the resolved path against it before the walk. After that check, a later swap of the final component fails on O_NOFOLLOW. A later swap of a directory fails on the per-directory O_NOFOLLOW open.

Restrict the fallback scalar parse to scalar results.
The fallback runs only when the whole front matter is invalid YAML. Each value is then passed through yaml.safe_load again. That parse can return non-scalar types:
argument-hint: [issue-id]becomes the list['issue-id']. Line 95 converts it to the string"['issue-id']". The bracket rebuild at lines 112-114 then never runs, so/helpshows['issue-id']. The strict YAML path shows[issue-id].description: Fix: the bugparses as the mapping{'Fix': 'the bug'}. Line 109 turns it into"{'Fix': 'the bug'}".
Keep the raw text unless the parse returns a boolean, None, or a string. Let lists pass through so lines 112-114 can handle them.

Authorization Bypass
Reachability: External
Exploitability: Moderate
CWE: CWE-863 — Incorrect Authorization
Bind MCP approval fingerprints to the workspace.
_fingerprint hashes only the server name and literal configuration, while approvals use a user-global path. An approval can therefore match the same definition in another workspace.
The stdio client does not set a separate working directory. Relative commands and module resolution can therefore execute workspace-local code. Saved servers can also connect automatically through mcp_auto_connect.
Include a resolved workspace scope in the fingerprint and pass it from MCPRegistry._approval_request.

Do not close fd after os.fdopen owns it.
The with os.fdopen(fd, ...) block closes fd when it exits. After that, a failure in os.replace or self.path.chmod enters the except branch. That branch calls os.close(fd) again.
This process runs other threads, such as the agent loop and to_thread workers. One of them can reuse that descriptor number in the meantime. The second os.close can then close an unrelated open file or socket.
Close fd manually only before os.fdopen takes ownership.

Build mcp_auto_connect from the project file only, not from the layered options.
_options() calls SessionOptions.load, which merges the user and env layers with the project layer. remember_mcp (Lines 90-99) and forget_mcp (Lines 113-119) filter the merged options.mcp_auto_connect list. They then write the full list to .nooa/settings.yaml in project scope. As a result, any server name in a user's personal coding.mcp_auto_connect is copied into the shared, committed project file. Other collaborators then try to auto-connect servers they do not have, and connect_session_mcp shows warnings for each one. test_skills_control_settings_scope.py guards this exact cross-scope leak for skills. The MCP preferences need the same guard.
Read the current list from the project settings file. Then apply the add or remove to that list.

- agent.py: delegate() preserves a worker's already-produced report in the
failure message when Todo merging fails, instead of losing it (JobError has
no separate payload field); _delegation_label() now cuts at a dot followed
by whitespace/end-of-string, not the first dot anywhere (was truncating
objectives that name files, e.g. "agent.py").
- factory.py: a file-based custom agent module is registered in sys.modules
before exec_module() runs it, so postponed-annotation resolution
(dataclasses, typing.get_type_hints) can find it via cls.__module__.
- instructions.py: _read_instruction_file() re-checks the resolved boundary
after re-resolving a symlink, closing a TOCTOU window where a symlink
retargeted between discovery and read could point outside the repo.
- slash_commands.py: the invalid-YAML fallback parser now only substitutes a
parsed scalar/list/None for bool/str/list/None results, keeping raw text for
anything else (a dict parse used to surface its Python repr).
- controls.py: skills persistence now defaults missing project-scope keys to
[] instead of falling back to the layered self.config value, and updates
self.config from its own current value -- closes a residual leak where a
personal skill/dir absent from the project file still got copied into it.
/mcp status no longer goes fully blank when one server has an invalid
config; that server now shows "invalid configuration" instead.
- mcp_approval.py / mcp_registry.py: approval fingerprints now bind the
resolved workspace scope, so approving a server definition in one
workspace no longer silently approves the identical definition everywhere
(the stdio client has no separate cwd, so a relative command/module
resolves against whatever workspace runs it; approved servers can also
auto-connect on startup). Claude Code style "type" configs (e.g. "http")
now map onto core's "transport" field instead of being rejected outright.
The approval store's atomic write no longer double-closes its temp file
descriptor on a failure after os.fdopen() already took ownership of it.
- workspace_settings.py: remember_mcp() rejects a literal secret in headers/
env (requires a ${VAR} placeholder) before writing to the workspace's
committed .nooa/settings.yaml; remember_mcp()/forget_mcp() now read
mcp_auto_connect from the project-scope file only, closing the same
cross-scope leak class fixed for skills in controls.py.

Use a unique module name for each file-based agent before you register it in sys.modules.
Line 118 gives every file-based agent the same module name, _nooa_custom_agent. Line 126 now registers that name in sys.modules. A second call to load_agent_class with a different file replaces the first module entry. This can happen on an agent swap. It can also happen when a protocol host loads ./agent.py:MyAgent from two workspaces.
After the replacement, sys.modules[cls.__module__] for the first class returns the second file's module. Two consumers use that lookup to resolve string annotations: typing.get_type_hints() and dataclasses. They then read the wrong file's globals. The result is NameError, or types that come from another workspace's file.
Derive the module name from the resolved file path.

Also reject literal credentials in url and args before saving.
The new guard checks only headers and env. remember_mcp still writes definition["url"] and definition["args"] to the project .nooa/settings.yaml without a check. Many MCP servers take credentials in the URL, for example ?api_key=... or https://TOKEN@host/.... Stdio servers often take them in args, for example --token sk-.... _safe_http_target in mcp_approval.py already redacts URL userinfo and query values because they can hold secrets. resolve_approved_environment resolves ${VAR} in every string field, so placeholders already work in these fields.
Reject URL userinfo and query values unless each one is a ${VAR} placeholder. For args, reject a literal value that follows a credential-style flag (--token, --api-key, --password), or at least warn about it.

Keep the registry entry aligned with the saved definition before refreshing settings.
When watch_settings=True, remember_mcp saves the normalized definition and then calls refresh_settings(). If the server is registered in memory or already defined in settings, the entry is present in registry._servers. A difference between that entry and the saved definition places the server in changed; a connected server is then deactivated and detached.
Servers that exist only in .mcp.json are not affected because refresh_settings() compares only entries in registry._servers.

Filter null MCP masks before validating settings.
forget_mcp stores a null per-server value to mask inherited configuration. _project_auto_connect reads that project file directly and passes it to resolve_behavior_settings; SessionOptions.mcp_servers requires each value to be a mapping, so later MCP preference edits can raise ValidationError. SkillsControl resolves the project settings before every subcommand, so /skills can fail in the same state.
Filter null entries before constructing SessionOptions. Add regression coverage for forget_mcp followed by remember_mcp, and for /skills activate with mcp_servers: {x: null}.

This regression test passes on the old buggy code.
The file object from os.fdopen closes its descriptor internally. It does not call the patched nooa_cli.interactive.mcp_approval.os.close. The old code called os.close(fd) once in the except branch, so closed == [fd] and len(closed) == len(set(closed)) is true. After os.fdopen succeeds, the module must not call os.close at all. Assert that directly.

A host awaiting submit_and_wait() could not tell those apart, and the ACP adapter had to wait on a cancel-confirmation event with a 30s timeout and guess. The information exists at the settle sites, so keep it: cancel paths raise TurnCancelled, abandonment paths raise TurnAbandoned(reason). The InteractiveSessionDispatcher maps its own cancel-driven CancelledError to TurnCancelled and no longer returns None from submit(). dispatcher.py is the runner's only consumer, so the contract change stays inside this PR plus the adapter's use of it.

RepoTools._resolve() has always let an absolute or ..-containing path escape self._root (unchanged since before this PR's session-aware read/ probe helpers were added). That's intentional, not a bug to fix: a wired session already gives ShellTools.run() the same filesystem reach (host, or a Gym-seeded sandbox), and _path_exists/_path_is_file/_read_bytes route through that same session on purpose so RepoTools sees what the session sees. Adding containment to _resolve() alone would be a boundary RepoTools doesn't actually have once a session is shared. Document the real contract instead: root is a default base for relative paths and result display, not a sandbox. Callers who need to keep an agent inside a tree do that by not wiring a session/ShellTools that reaches outside it.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
A runner-side cancel ends the foreground turn with CancelledError instead of TurnCancelled.
_on_done is attached as a done callback when the dispatch task is created (Line 566). cancel_turn and _cancel_turn_in_lifecycle start waiting on that task later. When the task is cancelled, asyncio runs _on_done first. That holds for the same-loop task and for the worker-loop wrapper, because the _task wrapper is registered on _source_future before the second wrap_future created at Line 1074 or Line 1061.
The sequence is:
_on_donecalls_finish_foreground(error=asyncio.CancelledError())(Line 782).cancel_work()then calls_finish_foreground(error=TurnCancelled())(Line 636). This call does nothing becausecompletion.done()is already true.asyncio.wrap_future(completion)copies the storedCancelledErrorinto the awaiting future.- The
awaitat Line 598 raisesCancelledError, even though the waiting task was never cancelled.
What callers see:
- Cancels started by the runner:
interrupt(),cancel_work()called directly,swap_agent(), andshutdown()all makesubmit_and_wait()raise a bareCancelledError. TheTurnCancelleddocstring promisesTurnCancelledhere. - Extra
cancel_work()call: theexcept asyncio.CancelledErrorbranch at Lines 599-601 runscancel_work()again. That flushes every queued channel and shuts down non-daemon jobs. dispatcher.py:InteractiveSessionDispatcher._run_active(Lines 85-88) has_cancel_requested == Falsein this case, so it passes the bareCancelledErrorto the host's task. That task was not cancelled, so the host misreads the error as its own cancellation.
test_cancel_work_settles_a_pending_foreground_with_turn_cancelled does not catch this. It sets no _task, so _on_done never runs.
Fix: save _cancel_requested before resetting it, and end the turn with a typed error. Also add a test that runs a real dispatch task, calls submit_and_wait(), then calls interrupt() or cancel_work(), and expects TurnCancelled.

pass include_daemons=True for a genuine final close. The rendered

dispatcher.cancel() no longer tears down infrastructure on a mid-turn
cancel. CodingAgent.close() passes include_daemons=True.
- SessionStore.open() opens the database with SQLite's mode=rw
(SQLiteStorageManager(must_exist=True)), so a session deleted between
the unlocked metadata read and the lock raises SessionNotFoundError
instead of being silently recreated empty under the old metadata.
- RepoTools.symbols() reports an unreadable file as a typed

ensure_dispatcher() mutates _task/_source_task/_source_future and reads _lifecycle_state/_cancel_requested with no _lifecycle_lock held, contradicting the PR's own claim that cross-thread cancel requests and the done-callback share one lock.
submit() holds _lifecycle_lock and, when not on the UI loop, marshals ensure_dispatcher via loop.call_soon_threadsafe (runs later, unlocked). If interrupt() is called before that deferred call runs, request_cancel() takes the lock, reads task = self._task as still None, and returns False (silently dropping the interrupt) even though its docstring promises truthful cross-thread cancellation; the turn the user just cancelled runs anyway.

_on_done settles a runner-initiated cancel with a bare asyncio.CancelledError() instead of the typed TurnCancelled/TurnAbandoned the rest of the system promises.
interrupt()/cancel_work()/swap_agent()/shutdown() cancel the dispatch task; _on_done (its done-callback) runs before cancel_work()'s own _finish_foreground(TurnCancelled()) and wins (first-write-wins). The bare CancelledError propagates through dispatcher.py's _run_active, which only converts to TurnCancelled when dispatcher._cancel_requested is True -- a flag only set by InteractiveSessionDispatcher.cancel(), never by a runner-level cancel. CodeRabbit flagged this exact line on the final review round; still open.

MCPControl.execute calls registry.refresh_settings() before every subcommand, including the read-only status display, and refresh_settings() can deactivate and detach a live, connected server as a side effect.
Server 'probe' is connected and activated. Its persisted settings-file entry drifts from registry._servers['probe'] (e.g. someone edits .nooa/settings.yaml, or a remember_mcp normalization mismatch). A user runs /mcp status purely to look at the table; refresh_settings() computes changed={'probe'} and calls deactivate(['probe']) + _detach('probe'), silently dropping a working connection and its tools as a side effect of a query.

An exception on a background-job dispatch turn (no foreground request pending) is reported only through _present(), which InteractiveSessionDispatcher wires to a no-op lambda, and _on_done never logs -- so the failure is swallowed with zero trace.
After submit() completes and _foreground is cleared, _dispatch()'s loop stays alive for background jobs. A delegate job finishes, _dispatch re-enters agent.handle(notification), and that turn raises. _on_done's _finish_foreground(error=error) is a no-op (self._foreground is None) and self._present(f'Agent error: {error}') goes to InteractiveSessionDispatcher's emit_text=lambda text: None. Nothing is logged or raised; the agent silently stops responding to that finished job with no diagnostic trail.

remember_mcp() persists the build_approval_request-normalized config while registry._servers still holds the un-normalized register()-time dict, so the immediate refresh_settings() always sees a mismatch and deactivates/detaches a currently-connected server.
self.mcp.register('gdrive', url='https://h/mcp') stores {'url': ...} with no transport key; after connecting, remember_mcp('gdrive') writes {'url': ..., 'transport': 'streamable-http'} (build_approval_request injects transport for URL entries) then calls registry.refresh_settings(), whose diff always finds a mismatch -> deactivate + _detach. Saving a working MCP server disconnects it every time, while remember_mcp's own return message claims 'Connection approvals are unchanged.'

_run_active's finally clears self._active_task even when it was the CALLING coroutine (not the inner dispatch task) that got cancelled externally, so the inner task keeps running detached while the dispatcher reports idle.
A host wraps await asyncio.wait_for(dispatcher.submit(text), timeout=5). On timeout, wait_for cancels submit()'s wrapping task; the inner task (wrapping runtime.submit_and_wait()) was never itself cancelled and keeps running. dispatcher._cancel_requested is False, so the bare CancelledError re-raises; finally clears _active_task so dispatcher.active reports False, but LocalAgentRunner._foreground stays occupied -- the next submit() raises RuntimeError('A prompt is already running') from inside the runtime even though the dispatcher claims idle.

cancel_work()'s self._finish_foreground(error=TurnCancelled()) is the last statement of its try block rather than in finally, so an exception from cancel_turn() or shutdown_queue_manager() leaves the foreground future permanently unsettled.
shutdown_queue_manager(flush=True) awaits queue_manager.shutdown() under a 30s asyncio.wait_for; if a job's cancellation blocks (a stuck to_thread shell command, an MCP OAuth wait), this raises TimeoutError before line 635 runs. A host awaiting submit_and_wait() hangs forever on a completion nothing else will settle.

The new self._summarization instance attribute is not declared nosnapshot like every sibling private field (_summarizers, _on_worker_spawned, _base_shell, _delegates_in), so session snapshot/restore captures and reinstates a stale SummarizationConfig on resume.
Session A runs with SummarizationConfig(policy='none'). The workspace's coding.summarization config is later changed. The user resumes session A: CodingAgent.init installs the new config, but AgentSnapshot.restore() then does setattr(agent, '_summarization', ), overwriting it. Every delegate()/spawn() from then on builds CodingWorker(summarization=self._summarization) with the stale policy -- delegated workers silently stop summarizing (or use the wrong policy) for the rest of that session.

remember_mcp() only rejects literal (non-${VAR}) secrets in the headers/env fields before writing to the shared .nooa/settings.yaml; url and args are unchecked, so credentials embedded there are committed in cleartext.
A server registered as {'url': 'https://TOKEN@host/mcp'} or {'args': ['--token', 'sk-live-...']} passes remember_mcp()'s validation untouched and is written verbatim to the project-scoped, version-controlled settings file that every collaborator and CI can read.

resolve_behavior_settings() raises a Pydantic ValidationError on a literal None in mcp_servers -- the exact null mask forget_mcp() writes -- because two callers read the project file with a raw yaml.safe_load() instead of the deep-merging load_layered_yaml() that would delete the None-valued key.
Call forget_mcp('x') once. Any subsequent remember_mcp() (via _project_auto_connect) or /skills command (via SkillsControl._project_scope_settings) constructs SessionOptions(**values) with mcp_servers={'x': None}; since SessionOptions.mcp_servers is typed dict[str, dict[str, Any]] with no | None, this crashes, breaking /skills and /mcp commands in that workspace until the null entry is hand-edited out.

set_dispatch_hooks() unconditionally overwrites _on_state_change/_on_before_handle/_on_after_handle/_on_notification with None, while dispatcher_exit and on_cancelled in the same method are only assigned when not None -- calling it to add one hook silently uninstalls four others.
A host constructs LocalAgentRunner(..., on_state_change=redraw, on_notification=log_jobs) and later calls runner.set_dispatch_hooks(on_cancelled=show_interrupted) to add just the cancel hook. This silently sets _on_state_change=None and _on_notification=None: UI redraws and background-job logging stop with no error, while dispatcher_exit/on_cancelled are correctly preserved by the asymmetric if ... is not None guard two lines below.
