`test_fresh_palace_via_full_stack_gets_cosine` used `tempfile.Temporary-
Directory()` as a context manager, which tries to delete the temp path
on exit. On Windows, ChromaDB still holds SQLite file handles to
`chroma.sqlite3` when the context closes, producing:
PermissionError: [WinError 32] The process cannot access the file
because it is being used by another process: '...\\chroma.sqlite3'
NotADirectoryError: [WinError 267] The directory name is invalid
Other tests in the same file use pytest's `tmp_path` fixture, which
defers cleanup to session end (when the process is exiting and the
file-lock contention is moot). Align this one with the rest of the
file.
CLAUDE.md already documents the 80% Windows coverage allowance due to
"ChromaDB file lock cleanup" — the fix is to stop fighting the lock.
Three tightly-coupled search-quality fixes for v3.3.3:
1. CLI `mempalace search` now routes through the same `_hybrid_rank`
the MCP path already used. Drawers whose text contains every query
term but embed as file-tree noise (directory listings, diffs, log
fragments) were scoring cosine distance >= 1.0 — the display formula
`max(0, 1 - dist)` then floored every result to `Match: 0.0`, with
no way for the user to tell a lexical match from a total miss. BM25
catches these cleanly; the display surfaces both `cosine=` and
`bm25=` so users see which component is firing.
2. Legacy-palace distance-metric warning. Palaces created before
`hnsw:space=cosine` was consistently set silently use ChromaDB's
default L2 metric, which breaks the cosine-similarity formula (L2
distances routinely exceed 1.0 on normalized 384-dim vectors). The
search path now detects this at query time and prints a one-line
notice pointing at `mempalace repair`. Only fires for legacy
palaces; new palaces already set cosine correctly.
3. Invariant tests pinning `hnsw:space=cosine` on every collection-
creation path — legacy `get_or_create_collection`, legacy
`create_collection`, RFC 001 `get_collection(create=True)`, the
public `palace.get_collection`, and a round-trip through reopen.
Locks down the correctness that new-user palaces already have so a
future refactor can't silently regress it.
Also adds a `metadata` property to `ChromaCollection` so callers can
read the underlying hnsw:space without reaching into `_collection`.
Tests:
- New regression: simulate three candidates at distance 1.5 (cosine=0),
one containing query terms — must rank first with non-zero bm25.
- New: legacy metric (empty or non-cosine) produces stderr warning.
- New: correctly-configured palace produces no warning.
- New: all five creation paths pin cosine metadata.
All existing tests still pass.
Previously a cross-wing topic tunnel for "Angular" stored the room as
"Angular" — colliding with a wing's literal folder-derived "Angular" room
at follow_tunnels/list_tunnels read time, and exposing raw topic strings
(which may contain characters rejected by sanitize_name) to the MCP
surface.
Topic tunnels now store their room as "topic:<original-casing>" and carry
kind="topic" on the stored dict. Explicit tunnels get kind="explicit"
(default). follow_tunnels("wing", "Angular") on a literal Angular room
no longer surfaces topic connections for the same name, and any LLM
scanning list_tunnels has a visible discriminator.
When two wings have one or more confirmed TOPIC labels in common, the
miner now drops a symmetric tunnel between them at mine time so the
palace graph reflects shared themes (frameworks, vendors, recurring
concepts).
- llm_refine: TOPIC label routes to a dedicated `topics` bucket so the
signal survives confirmation instead of getting collapsed into
`uncertain` and dropped.
- entity_detector / project_scanner: bucket plumbed through the
detection pipeline; `confirm_entities` returns confirmed topics
alongside people/projects.
- miner.add_to_known_entities: optional `wing` parameter records the
confirmed topics under `topics_by_wing` in
`~/.mempalace/known_entities.json`. Wing names do NOT leak into the
flat known-name set used by drawer-tagging.
- palace_graph: `compute_topic_tunnels` and `topic_tunnels_for_wing`
create symmetric tunnels via the existing `create_tunnel` API so they
share dedup and persistence with explicit tunnels.
- miner.mine: post-file-loop pass calls `topic_tunnels_for_wing` for
the freshly-mined wing. Failures are logged but never abort the mine.
- config: `topic_tunnel_min_count` knob (env
`MEMPALACE_TOPIC_TUNNEL_MIN_COUNT` or `~/.mempalace/config.json`),
default 1.
Tests cover topic persistence through init->mine, tunnel creation when
wings share a topic, no tunnel below threshold, cross-wing tunnel
retrieval via `list_tunnels`, dedup on recompute, case-insensitive
overlap, and the end-to-end mine-time wiring.
Out of scope for this PR (called out in the PR body): manifest-
dependency overlap, per-topic allow/deny lists, search-result surfacing.
`discover_entities` was deduping the convo_scanner results against the
manifest/git scan with a case-sensitive key, while every other dedup
path in the pipeline (`_merge_detected`, `miner.add_to_known_entities`)
uses case-insensitive matching. A project named `foo` in a manifest
plus `Foo` as a Claude Code `cwd` variant would surface as two review
entries instead of collapsing to one.
Fix keys `by_name` by `name.lower()` while preserving the first-seen
casing, matching the rest of the pipeline. Flagged by Copilot on #1175.
Regression test asserts a manifest project + a CamelCase-variant convo
cwd for the same real project collapse to one entry.
#1148, #1150, and #1157 were reviewed and merged on GitHub, but the two
stacked children landed on their parent feature branches (now stale)
rather than on develop. Only #1148's commits reached develop via the
direct merge. Release PR #1159 (develop → main for v3.3.3) is therefore
missing the LLM refinement, Claude-conversation scanner, and miner-
registry wire-up that were ostensibly part of the release.
This merge brings the stale `feat/llm-entity-refine` branch (which
contains the rolled-up merge commit for #1157 → #1150 → everything
below) into develop so the release tag includes it.
No code changes here — only history recovery.
Windows 8.3 short paths legitimately contain tildes (e.g. the CI runner's
USERPROFILE resolves to C:\Users\RUNNER~1\...), so asserting "~" is absent
from the expanded path fails on Windows even when expanduser worked
correctly. The equality check against os.path.abspath(os.path.expanduser())
is authoritative; drop the redundant absence heuristic.
The new abspath+expanduser normalization means /env/palace no longer
round-trips literally on Windows (abspath prepends the current drive,
producing D:\env\palace). Rewrite the env-var tests to compare against
os.path.abspath(os.path.expanduser(raw)) instead of hardcoded Unix
strings, and build raw paths with os.path.join so backslash-vs-slash
differences don't leak into assertions. Covers test_env_override, the
three new tests, and the legacy-alias test in test_config_extra.
MEMPALACE_PALACE_PATH (and legacy MEMPAL_PALACE_PATH) read from the
environment was returned as-is from Config.palace_path, while the
sibling --palace CLI path gets os.path.abspath() applied at
mcp_server.py:62. That inconsistency means env-var callers can end
up with literal '~' or unresolved '..' segments in the path, which
(a) breaks user intuition and (b) lets a caller who can set env vars
on the target user's session redirect palace storage to an
unexpected location.
Apply os.path.abspath(os.path.expanduser(...)) to the env-var branch
so both code paths converge on the same resolved absolute path.
Closes#1163
The init step's output was a dead file. miner.py has always read
`~/.mempalace/known_entities.json` to tag drawer metadata with
recognized names, but nothing ever wrote it — so init's careful
manifest + git + LLM detection work stopped at `<project>/entities.json`
and never reached the path that actually uses it.
Measured delta on a representative prose snippet (eight sentences
mentioning six real people and four real projects):
- Empty registry: 0 entities recognized (multi-word names fail the
frequency threshold; lowercase/hyphenated project names don't match
the CamelCase regex).
- Registry populated by init: 12 entities recognized (all correct, zero
false positives).
Every recognized name becomes a semicolon-separated metadata tag on the
drawer, which ChromaDB uses for entity-filtered search.
Implementation:
- `miner.add_to_known_entities({category: [names]})` reads the existing
registry, unions each category (case-insensitively, preserving first-
seen casing), and writes back. The function is tolerant of the two
on-disk shapes miner already supports: list of names, or dict mapping
name → code (dialect-style). In the dict case new names are added as
keys with `None` values so existing codes aren't overwritten.
- Invalidates the in-process mtime cache so same-process callers
(`cmd_init` → `cmd_mine` in one run) see the write immediately.
- Writes with `ensure_ascii=False` so non-ASCII names (Gergő Móricz,
Arturo Domínguez, etc.) stay readable on disk.
- Chmods 0o600 — the registry mirrors confirm-step PII from the user's
git authors and local paths.
cmd_init now calls this at the end of the confirm-entities step, after
the per-project `entities.json` is written (which is kept as an audit
trail the user can inspect or hand-edit). The per-project file is still
excluded from mining via `SKIP_FILENAMES` from the earlier fix.
17 new tests cover: fresh-file creation, list-category union, case-
insensitive dedup, preservation of untouched categories, dict-format
registries, malformed/non-dict file recovery, cache invalidation,
unicode round-trip, and an end-to-end verification that the miner's
`_extract_entities_for_metadata` picks up every registered name.
Addresses issues found while reviewing the initial phase-2 implementation
against real data:
**Bug: uncertain bucket starved from the LLM.**
`discover_entities` was dropping the regex-uncertain bucket whenever real
git/manifest signal existed — which is exactly when `--llm` is most useful
for cleaning up prose noise. The uncertain candidates never reached the
refinement step. Fixed: only drop when `llm_provider is None`.
**Context collection: word boundaries, not substring.**
`_collect_contexts` used substring matching on lower-cased lines, so the
name "Go" matched "good", "going", "forgot". Switched to a
`(?<!\w)…(?!\w)` regex so short names only match at token boundaries.
**Authoritative-source detection replaces confidence threshold.**
Previously the refinement step skipped entries with `confidence >= 0.95`
to avoid second-guessing manifest-backed projects. That threshold was
fragile — the regex detector produces 0.99 confidence for things like
`code file reference (5x)` on framework names (OpenAPI, etc.), so those
skipped the LLM despite being regex-only noise. New helpers
`_is_authoritative_person` / `_is_authoritative_project` look at the
actual signal strings (commits, package.json, etc.) to decide.
**Now also refines regex-derived people.**
After #1148's high-pronoun-signal fix, the regex detector can promote
non-people to the `people` bucket (e.g. a capitalized common noun that
happened to appear near pronouns). The LLM now gets a chance to clean
those up, while git-authored people are still skipped.
**Robust JSON extraction.**
Small local models routinely wrap JSON output in prose ("Sure, here's
the classification: {…}"). The previous code-fence stripper failed on
that. `_extract_json_candidates` now does balanced-bracket extraction
with string-aware quote handling, so it recovers JSON from:
- raw responses
- markdown fenced blocks
- JSON embedded inside surrounding text
- multiple candidate objects/arrays
**Prompt guidance for frameworks vs user projects.**
Added an explicit instruction: frameworks, runtimes, APIs, cloud
services, and third-party vendors (Angular, OpenAPI, Terraform, Bun,
Google, etc.) are TOPIC unless the context clearly says it's the user's
own codebase. Directly addresses a false-positive pattern observed
during dev runs.
**Defensive mtime.**
`convo_scanner._safe_mtime` catches OSError during `stat()` — permission
changes, filesystem races, broken symlinks — and sorts the affected file
to the end of the newest-first order rather than crashing the scan.
**Cosmetic:** merged two adjacent f-strings on the same line in
`backends/chroma.py` and `llm_client.py` (no behaviour change).
15 new tests cover the OSError fallback, word-boundary matching, JSON
extraction variants, authoritative-source helpers, refining high-
confidence regex projects, and end-to-end LLM refinement preserving the
uncertain bucket.
Takes the candidate set produced by phase-1 detection (manifests, git
authors, regex on prose) and asks an LLM to reclassify each candidate
as PERSON / PROJECT / TOPIC / COMMON_WORD / AMBIGUOUS.
Scale approach: never feed the raw corpus to the LLM. For each
candidate, collect up to 3 context lines from sampled prose, cap each
at 240 chars, batch 25 candidates per call. Keeps total input around
50-100K tokens even on large corpora and completes in a few minutes
on a 4B local model.
Interactive UX:
- Stderr progress bar with the current candidate name, updates
per-batch.
- Ctrl-C interrupts cleanly: returns a RefineResult with
`cancelled=True` and whatever was classified before the interrupt.
The partial result is safe to pass straight to confirm_entities.
- Per-batch errors (transport, parse) are recorded in `errors` and
don't abort the whole run.
Refinement scope: only `uncertain` and low-confidence `projects`
entries are sent. Manifest-backed projects (conf >= 0.95) and git-
authored people are already authoritative and skip the LLM.
Response parser is defensive — accepts `label` or `type` keys,
lowercase/uppercase variants, top-level list or wrapped object, and
strips markdown code fences. Unknown labels become AMBIGUOUS so the
user reviews them rather than silently accepting a bad classification.
`collect_corpus_text` provides a simple stratified prose sampler
(recent first, capped per-file) so callers don't need to build their
own corpus window.
28 tests with a FakeProvider (no network). Covers context collection,
prompt building, response parsing variants, classification apply,
end-to-end refine, and Ctrl-C partial-result behavior.
Three providers cover the useful space while keeping the zero-API
default:
- `ollama` (default): local models via http://localhost:11434. Works
fully offline. Tag-matching check accepts both `model` and
`model:latest` forms.
- `openai-compat`: any /v1/chat/completions endpoint. Covers
OpenRouter, LM Studio, llama.cpp server, vLLM, Groq, Together,
Fireworks, and most self-hosted frameworks. API key falls back to
$OPENAI_API_KEY. Endpoint normalization is forgiving about trailing
`/v1`.
- `anthropic`: Messages API v2023-06-01. API key falls back to
$ANTHROPIC_API_KEY. Concatenates multi-block text responses.
JSON mode is normalized across providers — Ollama uses
`format: "json"`, OpenAI-compat uses `response_format`, Anthropic uses
prompt-level instruction. Callers request JSON once; this module
handles the provider-specific plumbing.
No external SDK dependency; stdlib `urllib` throughout. HTTP errors
are wrapped into a single `LLMError` class so callers don't need to
distinguish transport, auth, and parse failures at the call site.
26 tests, all with mocked HTTP — suite runs offline with no real
provider required.
Claude Code stores sessions under `~/.claude/projects/<slug>/<id>.jsonl`
where `<slug>` is the original CWD with `/` replaced by `-`. That
encoding is lossy — can't distinguish `foo-bar` (one segment) from
`foo/bar` (two) — so slug-decoding alone produces wrong names for any
hyphenated project.
Fortunately, every message record carries a `cwd` field with the true
path. This scanner reads one record per session to recover the
accurate project name deterministically, falling back to slug-decoding
only if the JSONL is malformed or empty.
Output shape matches project_scanner.ProjectInfo so the discover
orchestrator can union results across sources. Session count doubles
as a density signal for ranking.
22 unit tests cover: root detection, cwd extraction with malformed
input tolerance, fallback slug decoding, name resolution using the
newest session (so renames win), and dedup when two encoded dirs
resolve to the same project.
`mempalace init` previously leaned entirely on regex-based entity
extraction from prose. That path works for text-only folders but wastes
signal in any codebase: the project's own name is already in
`package.json` / `pyproject.toml` / `Cargo.toml` / `go.mod`, and the
people who worked on it are in `git log`.
This adds `project_scanner.py`, which becomes the primary signal source
when real signal is available, with the regex detector preserved as the
fallback for prose-only folders (diaries, research notes, writing).
What it does:
- Walks the target directory, parses manifests for canonical project
names, and detects git repos by the presence of a `.git` directory.
- For each repo, reads `git log` for authors and filters obvious bots
(`[bot]`, `dependabot`, `renovate`, `github-actions`, names ending in
`bot`, `-autoroll`). Importantly does NOT filter
`@users.noreply.github.com` - that's GitHub's privacy-protected human
email, used by real contributors.
- Resolves author aliases with a union-find: commits that share a name
OR an email collapse into one person. Picks the most-frequent
real-name variant as display, ignoring handles and single-token
usernames.
- Flags "mine" projects: user is top-5 committer OR has >=10% of
commits OR >=20 commits. Ordered by user_commits in the UX.
- `discover_entities()` merges scanner results with the regex detector
case-insensitively (so `mempalace` from pyproject absorbs `MemPalace`
from docs), and suppresses the regex `uncertain` bucket when real
signal is already found - the user doesn't need to adjudicate prose
noise when the answer is already in git.
Integration: `cmd_init` now calls `discover_entities` instead of
running the regex detector directly. Same output shape, so
`confirm_entities` works unchanged.
Ships with 39 new tests covering manifest parsing, bot filtering,
union-find dedup, git repo discovery, scan integration, and
merge/fallback behavior. Existing 56 regex-detector tests all pass.
The pattern-matching detector had several systematic false positives that
crowded the init review with nonsense. Concrete fixes:
- CamelCase extraction: add `[A-Z][a-z]+(?:[A-Z][a-z]+|[A-Z]{2,})+` to
candidate patterns so `MemPalace`, `ChromaDB`, `OpenAI`, `ChatGPT` are
visible. Previously `MemPalace` fragmented into `Mem` + `Palace`.
- Dialogue `^NAME:\s` requires >=2 matches to count. A single metadata
line like `Created: 2026-04-21` was scoring as dialogue and classifying
`Created` as a person.
- Versioned/hyphenated pattern tightened to `\b{name}[-_]v?\d+(?:\.\d+)*\b`
(version-only). The previous `\b{name}[-v]\w+` matched `context-manager`,
`multi-word`, etc. - every hyphenated compound.
- Skip LICENSE/COPYING/NOTICE/AUTHORS/PATENTS files during scan. They
produce pure-English-prose noise (`Contributor`, `Software`, `Covered`,
`Before`).
- Extra SKIP_DIRS: `.terraform`, `vendor`, `target`.
- Expand stopword list with capitalized participles/descriptors that
commonly appear at sentence start: `created`, `updated`, `extracted`,
`processed`, `total`, `summary`, `auto`, `multi`, `hybrid`, `context`,
`bridge`, `batch`, `local`, `native`, `never`, `before`, `after`, etc.
- classify_entity: high-pronoun single-category signal now classifies as
person. A diary's main character gets referenced with pronouns, not
dialogue markers - requiring two signal categories demoted `Lu` (16
pronoun hits across 30 mentions) to uncertain. Gate on
`pronoun_hits >= 5 AND pronoun_hits / frequency >= 0.2` so common
sentence-start words (`Never`, `Before`) with incidental proximity
stay uncertain.
#1097 fixed mempalace_search to treat empty-string wing/room as
no filter, matching how LLM agents default to filling every optional
parameter with ''. The same pattern wasn't applied to diary_read:
passing wing='' defaulted to wing_<agent_name>, siloing away entries
that hooks had written to project-derived wings per #659.
When wing is empty/omitted, filter only on agent + room=diary so
callers get a unified view of the agent's journal across every wing
it has written to. Explicit wing=<name> continues to scope reads
to that wing only.
Adds test covering empty-wing read after writing to both the default
and a non-default wing.
_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.
The legacy hook scripts `hooks/mempal_save_hook.sh` and
`hooks/mempal_precompact_hook.sh` shell out to `python3` for JSON
parsing and transcript-message counting. On macOS GUI launches of
Claude Code — `open -a`, Spotlight, the dock — the harness inherits
`PATH` from launchd (`/usr/bin:/bin:/usr/sbin:/sbin`), which may not
contain a `python3` at all, or may contain only a system Python that
lacks what the hook needs. The hook then fails silently in the
background log where users never look.
`mempalace` auto-ingest itself is unaffected — #340 switched that
path to the `mempalace` CLI entry point, which pipx/uv install on a
stable global PATH.
This PR adds a `MEMPAL_PYTHON` environment variable that users can
set to point the hook at any Python 3 interpreter. Resolution order
applied at each `python3` invocation site inside the two hooks:
1. $MEMPAL_PYTHON (if set and executable)
2. $(command -v python3) on PATH
3. bare `python3` as a last resort
The interpreter does not need `mempalace` installed in it — only the
standard-library `json` and `sys` modules. The hook's `mempalace mine`
call runs via the CLI, independent of this override.
hooks/README.md documents the macOS GUI PATH issue and the
MEMPAL_PYTHON override. tests/test_hooks_shell.py adds 3 regression
tests (Linux/macOS only, POSIX bash):
- MEMPAL_PYTHON override wins over PATH (proved via a
marker-emitting shim that proxies to the real interpreter).
- Non-executable MEMPAL_PYTHON falls back to PATH rather than
crashing on permission denied.
- Unset MEMPAL_PYTHON resolves via PATH.
`hooks_cli.py` (the Python implementation invoked via
`mempalace hook run ...`) already uses `sys.executable` and is
therefore trivially correct — no changes needed there.
Supersedes abandoned branch `fix/hook-bugs`.

Three assertions in test_mcp_command_* were still checking for the old
`python -m mempalace.mcp_server` output string. Update to match the new

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
