+# PR #62 / Issue #60 Linux follow-up review
+
+**Scope.** Reviewed base `1d7b7dab58a10fe86fd747b7290d47674ca93230` through head `6a4e385a78c8a561d5cf3644336de6a352ea9271` in the assigned review-only worktree. HEAD and tree matched the brief; the worktree was clean. No source files, branches, services, or user data were changed.
+
+**NOT PASS findings**
+
+1. **`auth_ok()` accepts a non-executable home install.** At `.agents/skills/lib_py/agents/adapters/opencode.py:317-321`, the `PATH` candidate is checked by `shutil.which`, but the home candidate is accepted by `os.path.exists` alone. Reproduction: with a temporary HOME containing `.opencode/bin/opencode` mode `0644`, an empty PATH, and no XDG variables, `adapter.auth_ok()` returned `True`. `create_session.sh` now relies on this result as its preflight, so it can report the installation as functional and proceed although the CLI cannot be executed. Check that the home candidate is a regular executable file (e.g. `os.path.isfile` and `os.access(..., os.X_OK)`), and cover a non-executable file and directory in the auth tests.
+
+2. **The placeholder regex can discard a real draft.** `.agents/skills/lib_py/agents/adapters/opencode.py:76-79` makes the example suffix optional, so the pattern matches the exact user text `Ask anything…`. Replaced the captured prompt line in the 2.x home fixture with that text and `extract_input_region()` returned `''`. Thus the existing input-empty signal loses this exact draft and can treat a non-empty prompt as idle. The observed 2.x placeholder fixtures include an opening quote and example, including the truncated narrow capture; constrain the pattern to that observed shape and add the exact-short-text draft as a regression case. Other tested similar strings are retained.
+
+3. **Five newly added Mac tests fail before exercising `_ro_connect`.** In `tests/test_issue60_linux_fixes.py:153-155`, the `clean` fixture closes a WAL-mode connection and assumes macOS SQLite removes both sidecars. On this Mac the files remain after close, so `make("clean")` returns `opencode.db`, `opencode.db-shm`, and `opencode.db-wal` and the assertion at `:181` fails before the query runs. This affects the five `_descendants`, `_has_session`, `discover`, `residual_artifacts`, and `verify_artifact` parameterizations. Normalize the fixture to a genuine no-WAL state after closing/checkpointing the writer (or construct the clean database in rollback-journal mode) before asserting the directory contents.
+
+**Validation.** On macOS / Python 3.9.6, ran the focused suite with temporary HOME/TMPDIR, XDG variables unset, the required environment scrub, `PYTHONDONTWRITEBYTECODE=1`, `-p no:cacheprovider`, and an external temporary basetemp:
+
+`tests/test_issue60_linux_fixes.py tests/test_a4_adapter_contract.py tests/test_issue31_purge_residual.py tests/test_issue50_dispatch.py`
+
+Result: **189 passed, 5 failed** (136.27s). All five failures share the clean-fixture setup issue above; the other WAL states and remaining focused tests passed. A separate no-WAL temporary DB probe exercised `verify_artifact`, `discover`, `_has_session`, `_descendants`, and `residual_artifacts`; each returned the expected result and left only `opencode.db`. The non-executable-file probe reproduced finding 1; the captured-pane probe reproduced finding 2. `git diff --check` and `bash -n` on the changed create/stop scripts passed. No actual OpenCode service or real data was accessed. Linux was not independently rerun in this turn.

+# PR #62 / Issue #60 Linux follow-up review, round 2
+
+**Scope.** Reviewed base `1d7b7dab58a10fe86fd747b7290d47674ca93230` through head `6a37c0019baa31ee28b32a086e57b4c8239413c4` in the assigned review-only worktree. HEAD and tree matched the brief, and `git status --short` was empty. No source changes, commits, branch operations, or real service/data access were performed.
+
+The three findings from round 1 are addressed:
+
+- `.agents/skills/lib_py/agents/adapters/opencode.py:76-80` now requires the quote/example portion of the observed placeholder. `tests/test_issue60_linux_fixes.py:79-91` verifies that both the bare `Ask anything…` and `Ask anything...` typed drafts are retained, while the wide and truncated-narrow UI placeholders still read as empty.
+- `opencode.py:318-324` accepts the home install only when it is a regular executable file; the test at `tests/test_issue60_linux_fixes.py:334-341` rejects both a non-executable file and a directory.
+- `tests/test_issue60_linux_fixes.py:156-164` removes macOS-persistent WAL sidecars only after closing the last writer, to normalize the no-WAL fixture. The clean-state queries then pass, confirming committed rows remain available after fixture setup. The other three sidecar states still exercise the intended code paths.
+
+The follow-up also replaces direct writable SQLite opens in the two status branches (`.agents/skills/multi-agent-mux-status/scripts/status.sh:115-119,316-320`) and reconciler (`.agents/skills/multi-agent-mux-monitor/scripts/reconcile.sh:953-959`) with the adapter's `_ro_connect`, avoiding sidecar creation/removal in these readers. Their scripts receive the skill directory through the existing `env_python` bootstrap, so the new adapter import resolves in the normal execution path. The change preserves the prior status result mapping and query semantics.
+
+No new blocking issue found. The `_DB_PATHS` cache remains scoped to binary path and effective HOME/data-home, with its test fixture clearing the cache between tests; the previously noted narrow immutable/WAL race remains a transient-read caveat rather than a new data mutation path. No live OpenCode command, service, or user database was accessed.
+
+**Validation.** On macOS / Python 3.9.6, ran the related suite from the review worktree with temporary HOME/TMPDIR, XDG variables unset, the required environment scrub, `PYTHONDONTWRITEBYTECODE=1`, `-p no:cacheprovider`, and an external temporary basetemp:
+
+`tests/test_issue60_linux_fixes.py tests/test_a4_adapter_contract.py tests/test_issue31_purge_residual.py tests/test_issue50_dispatch.py`
+
+Result: **201 passed** (136.01s). `git diff --check` and `bash -n` on the changed status, reconcile, create, and stop scripts also passed. Linux was not independently rerun in this reviewer turn; the brief records the author's Linux run.
