`bash` on the Windows CI runner resolves to `wsl.exe` which fails with
"Windows Subsystem for Linux has no installed distributions." The shell
hooks themselves are POSIX-only — Windows users use the Python entry
point — so the bash-subprocess exercise is non-applicable on win32.
The static-grep validator tests still run on every platform, so the
shell-side validation is still asserted under Windows; only the live
bash invocation is skipped.
Address Copilot review on #1231:
1. Stop double-mining the transcript on the Python side. ``_get_mine_targets``
now returns only the ``MEMPAL_DIR`` projects target — the convos target
for the transcript dir is dropped because ``_ingest_transcript`` already
handles it on every hook fire. The duplicate spawn was using
``sys.executable`` (vs ``_mempalace_python()``) and a different ``--wing``,
so each Stop/PreCompact event was writing the same transcript into two
wings under asymmetric interpreters and overwriting the single
``_MINE_PID_FILE`` lock.
2. ``_maybe_auto_ingest`` and ``_mine_sync`` now spawn via
``_mempalace_python()`` so the resolved interpreter matches the venv
that owns mempalace (matters under GUI-launched harnesses where
``sys.executable`` may resolve to a system Python without chromadb).
3. Replace ``eval $(...)`` in both shell hooks with a ``mapfile``-based
reader. Sanitized values are still emitted by the same Python parser,
but the shell now does plain variable assignment instead of executing
the parser's stdout — smaller blast radius if the sanitizer is ever
bypassed.
4. Mirror ``_validate_transcript_path`` in the shell hooks via a
``is_valid_transcript_path`` helper — extension + traversal-segment
rejection, parity with the Python validator. The convos mine in each
shell hook is now gated on the validator instead of bare ``-f``.
5. Tighten the ``..`` traversal test that previously exercised the
suffix gate by mistake (``../../etc/passwd`` lacks ``.json[l]``).
Use ``.jsonl`` paths with traversal segments to actually hit the
``..`` rejection branch.
6. README: add a one-liner pointing at ``mempalace sweep`` for users
who want per-message recall on top of the file-level chunks the
hooks produce. The sweeper was undiscoverable previously.
Tests: 1418 passed, 1 skipped (full suite minus benchmarks).
#1230 fixed --mode convos for the case where MEMPAL_DIR was unset, but
left two configurations broken:
- MEMPAL_DIR set to a project dir: convos never mined (MEMPAL_DIR
overrode the transcript path); only project files were ingested.
- MEMPAL_DIR set to a conversations dir per the old hooks/README: the
projects miner ran on JSONL — same wrong-miner behaviour.
The shell hooks (mempal_save_hook.sh, mempal_precompact_hook.sh) had
the same MEMPAL_DIR-overrides-transcript bug AND were missing --mode
on every spawned `mempalace mine` call.
Make the auto-ingest *additive*. _get_mine_dir → _get_mine_targets,
returning a list of (dir, mode) pairs:
- MEMPAL_DIR (when valid) contributes (dir, "projects")
- A valid transcript JSONL contributes (parent, "convos")
- Both can appear together; the hook spawns one ingest per target
Same change applied to the shell save and precompact hooks. Precompact
also gained transcript_path parsing so it can run the convos mine
synchronously before context is compressed. hooks/README.md updated to
describe MEMPAL_DIR as a project-files target, never a convos target.
TDD: test written first, failed, then fixed.
Problem: save hook says "saved in background" but MEMPAL_DIR defaults
to empty, so nothing actually mines. Users get no auto-save despite
the hook firing every 15 messages.
Fix: use TRANSCRIPT_PATH (received from Claude Code in the hook's
JSON input) to discover the session directory. Mine that directory
automatically. MEMPAL_DIR is still supported as override but no
longer required.
Also fixed: bare python3 → $(command -v python3) for nohup safety.
