#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.
- Normalize MEMPAL_DIR via Path.expanduser().resolve() so ~/proj paths
are correctly accepted instead of falling through to transcript fallback
- Replace bare Path.expanduser().is_file() transcript check with the
existing _validate_transcript_path() which adds .resolve(), enforces
.jsonl/.json extension, and rejects '..' path-traversal components
- Update tests to compare resolved paths (cross-platform correctness)
- Add tests for tilde expansion, path-traversal rejection, and
non-jsonl extension rejection in _get_mine_dir

The Stop and PreCompact hooks spawn `mempalace mine <dir>` with no
`--mode` flag, which defaults to `projects` in cli.py. When MEMPAL_DIR
is unset, _get_mine_dir falls back to the parent of the transcript
JSONL — and miner.py's READABLE_EXTENSIONS includes `.jsonl`, so the
projects miner happily ingests Claude Code session JSONL as if it were
source code instead of conversation.
Make _get_mine_dir return (dir, mode): MEMPAL_DIR keeps `projects`,
the JSONL fallback yields `convos`. Both _maybe_auto_ingest and
_mine_sync now thread the mode into the spawned command.
_wing_from_transcript_path only matched '-Projects-<name>' segments,
so Linux users with code under ~/dev/, ~/code/, or ~/src/ fell through
to the wing_sessions fallback and lost the per-project diary scoping
introduced in #659.
Broaden the heuristic to derive the project from the final
dash-separated token of the encoded project-folder name under
.claude/projects/. Keeps the legacy -Projects- regex as a secondary
match for transcripts living outside the standard Claude Code path.
Covers macOS Users layout, Linux dev/code layouts, and deeper nested
source paths while preserving existing Projects/ behavior.
* fix: add wing param to diary_write/diary_read, derive from transcript path
Without a wing override, all diary entries from the stop hook land in
wing_session-hook regardless of which project the session is in, making
per-project diary search impossible.
- tool_diary_write(): add optional `wing` param; sanitize and use it when
provided, fall back to wing_{agent_name} when omitted
- tool_diary_read(): add optional `wing` param for filtering by target wing
- TOOLS dict: expose `wing` in input_schema for both diary tools
- hooks_cli: add _wing_from_transcript_path() helper that extracts the
project name from Claude Code paths like
~/.claude/projects/-home-jp-Projects-kiyo-xhci-fix/... → kiyo-xhci-fix
- hook_stop: derive project wing and append wing= hint to block reason so
Claude writes diary entries to the correct per-project wing

* fix: wing_ prefix + agent filter on diary_read
Addresses bensig's 2-issue review on this PR.
1. _wing_from_transcript_path() was returning bare project names
(e.g. "myproject") while all existing wings follow the wing_*
convention from AAAK_SPEC. Entries landed in wing="myproject"
while diary_read defaulted to wing="wing_<agent_name>" —
orphaning every diary entry written by the stop hook. Now
returns "wing_<project>" and falls back to "wing_sessions".
2. tool_diary_read() did not include agent_name in the ChromaDB
where filter when a custom wing was provided — any caller with
a shared wing could read entries written by other agents.
Add {"agent": agent_name} to the $and clause. Also flagged by
Qudo and left unresolved until now.
Tests updated to expect the wing_ prefix (6 tests).

Clean squash by jphein on 2026-04-21. Backwards-compatible via hook_silent_save config flag. Save marker now only advances after confirmed write — strictly safer than status quo.
Adds a `hook_silent_save` mode (default `true` in new installs) where
the stop and precompact hooks write diary entries directly via the
Python API — no AI block, no MCP tool roundtrip, no possibility of the
AI forgetting or ignoring the save instruction.
**Two modes, controlled by `hook_silent_save` in `~/.mempalace/config.json`:**
1. **Silent mode** (default): Direct call to `tool_diary_write()`. Plain
text, no AI involved, deterministic. Save marker advances only after
the write is confirmed, so mid-save failures do not lose exchanges.
Shows `"✦ N memories woven into the palace"` as a systemMessage
notification so the user knows the save fired.
2. **Block mode** (legacy): Returns `{"decision": "block"}` asking the
AI to call the MCP tool chain. Non-deterministic — the AI may ignore,
summarize lossy, or fail. Kept for backward compatibility.
**Extras rolled in:**
- Block reasons name "MemPalace" explicitly and instruct the AI not to
write to Claude Code's native auto-memory (.md files) — prevents the
two memory systems from stepping on each other.
- Codex transcript handling (`event_msg` payloads) in
`_count_human_messages` + `_extract_recent_messages`.
- Tightened stopword leak in diary summaries; docstring polish; test
hermeticity fixes (per-test `STATE_DIR` patching).
**Tests:** hooks_cli tests cover silent-save path, save-marker
advancement after confirmed write only, and systemMessage formatting.
Rebased fresh on upstream/develop. Only touches files germane to the
feature (hooks_cli.py, tests, hooks/README.md, HOOKS_TUTORIAL.md) —
stale fork-local `.sh` wrapper and plugin manifest changes dropped.
Every stop hook fire spawned a new background `mempalace mine` via
subprocess.Popen with no dedup — 4 concurrent mines at ~770% CPU
observed in production. Add `_mine_already_running()` (reads
`hook_state/mine.pid`, uses `os.kill(pid, 0)` as an existence check)
and `_spawn_mine()` (writes the child PID to the lock file after
Popen returns). `_maybe_auto_ingest` bails early when the guard
reports True.
Tests: 4 new unit tests for `_mine_already_running` (no file, dead
PID, live PID using `os.getpid()`, corrupt file), 1 new test
covering the skip-when-running branch of `_maybe_auto_ingest`, and
existing spawn tests patched to redirect `_MINE_PID_FILE` into
tmp_path so they don't touch the real state dir.

- _output(): use sys.modules.get() instead of unconditional import to
avoid triggering mcp_server's stdout redirect as a side effect
- _output(): write-all loop for os.write() to handle partial writes and
EINTR; fall back to sys.stdout.buffer on OSError
- _output() docstring: remove inaccurate _save_diary_direct reference
- stop_hook_active guard: narrow except to ImportError/AttributeError,
default silent_guard=False (safe: preserves block-mode loop prevention
when config load fails) and log a warning instead of silently changing
behavior
- tests: two new regression tests covering the real-stdout-fd path and
the fd-1 fallback path

* fix(hooks): stop precompact hook from blocking compaction
The precompact hook unconditionally returned {"decision": "block"},
which in Claude Code means "cancel compaction" with no retry mechanism.
This made /compact permanently broken for all plugin users.
Changed hook_precompact() to mine the transcript synchronously (so data
lands before compaction) and return {"decision": "allow"}. This matches
the standalone bash hook in hooks/ which already uses allow.
Also extracted _get_mine_dir() and _mine_sync() helpers so precompact
can mine from the transcript directory, not just MEMPAL_DIR.
Stop hook behavior is unchanged -- left for #673 which implements the
full silent save path.
Closes#856, closes#858.
* fix: use empty JSON instead of invalid \"allow\" decision value
Claude Code only recognizes \"block\" as a top-level decision value.
\"allow\" is a permissionDecision value for PreToolUse hooks, not a
valid top-level decision. The correct way to not block is to return
empty JSON. Caught by #872.
- _count_human_messages() now logs a WARNING via _log() when a
non-empty transcript_path is rejected by the validator, making
silent auto-save failures diagnosable via hook.log
- Add test for platform-native paths (backslashes on Windows) to
verify _validate_transcript_path works cross-platform
- Add test verifying the warning log is emitted on rejection
