This should probably use the Match struct or at least have line numbers.
Or should it be a diff?

has_stdin but not the value of stdin? or is the value baked into the command?

This means you get two events for each terminal command? One for stdout, one for stderr?

It also doesn't match command finished, which has both stdout and stderr.

WalkthroughThe PR adds durable interactive coding sessions, structured shell activity events, timeout propagation, SQLite session lifecycle operations, compatibility handling, public exports, documentation, and comprehensive tests. ChangesInteractive coding sessions
Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to The PR adds persistent concurrent sessions and shared coding activity, but current behavior can report file changes differently from the bytes written and can leave or mutate session-side files during read and delete operations. These bounded correctness and file-state risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

686-693: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueAvoid creating a lock file when there is nothing to delete.
_acquire_session_lockopens the lock path withO_CREAT. If the database and its sidecars do not exist, this call still creates<name>.lock, and the function intentionally never unlinks it. Repeated deletes of unknown session IDs therefore leave permanent.lockresidue in the sessions directory.SessionStore.deletereaches this path on any missing ID whose parent directory exists, for example the secondstore.delete("delete-me")call inpackages/nooa-cli/tests/test_sessions.pyline 166.Skip the lock when no target file is present. The subsequent locked check keeps the delete race-safe.

replacement instead of the text written by ShellTools.replace(). In the replace
flow around Match handling and FileEdit construction, normalize new_text using
the same trailing-newline behavior as ShellTools.replace() before building
bounded_new and diff, or reuse the effective replacement returned by replace;
update the corresponding test expectation to include the written trailing
newline.

ShellTools.replace() re-terminates a Match region when the replacement lacks a trailing newline and content follows it. The activity observer built FileEdit from the pre-normalized text, so an edit could report "changed" while the file held "changed\n". FileWrite now carries the text as written and the observer reports from it, keeping the normalization rule in one place. The attribute stays out of __str__, so tool output is unchanged.

The TUI branch predates the review rewrite of #82, so it was written against a session module that no longer looks the same: * Sessions moved from `nooa.sessions` to `nooa_cli.sessions`. * `SessionStore.create()` renamed its `host` argument to `origin`, so the TUI now records `origin="tui"` alongside the ACP host's `origin="acp"`. * `SessionResumed` and `SessionCleared` were dropped from the module when it was descoped, and are restored here. Both are transient `EventBase` types, so they stay out of `SESSION_EVENT_TYPES`, which is the set persisted with the session. `turn_count` also changed meaning: it now counts user turns only, which is what the live `record_user` path always did. The old summary query counted agent messages too, so the two disagreed. The test asserting the previous value is updated rather than the merged behavior. One unrelated fix: the bang-shell cwd assertion compared an unresolved temp path, which fails on macOS through the /var symlink. Signed-off-by: Paul Furgale <pfurgale@nvidia.com>
