v3.3.3

### Bug Fixes

- **Install regression** — `mempalace-mcp` console script is now declared in `pyproject.toml` alongside `.claude-plugin/plugin.json`'s reference to it. In v3.3.2 the two drifted apart (plugin.json shipped the new `"command": "mempalace-mcp"` form before the matching entry point landed), so every fresh `pip install mempalace==3.3.2` produced a Claude Code plugin config pointing at a binary that wasn't installed. (#1093, #340)
- Restore silent-save visibility after the Claude Code 2.1.114 client regression — production transcript saves were failing silently until this PR. (#1021)
- Paginate `status`-path metadata fetches so large palaces don't trip SQLite variable limits. (#851)
- Resolve the Claude plugin hook runner across platform / plugin-dir variations; previously broke on Windows and some macOS layouts. (#942)
- Real `python3` resolution for `.sh` hooks with a `MEMPAL_PYTHON` override path. (#833)
- Add optional `wing` parameter to `tool_diary_write` / `tool_diary_read` and derive per-project wing from the Claude Code transcript path when writing from the stop hook — diary entries from different projects no longer collapse into a shared default wing. (#659)
- Treat empty string as "no filter" in `mempalace_search` `wing`/`room`; LLM agents that default to filling every optional parameter with `""` no longer get bounced with `must be a non-empty string`. (#1097, #1084)
- Broaden `_wing_from_transcript_path` to handle Claude Code project folders without a `-Projects-` segment (e.g. `~/dev/<parent>/<project>`, `~/code/<project>`). The project name is now derived from the final dash-separated token of the encoded folder, so Linux users with code outside `~/Projects/` get per-project diary scoping instead of falling through to `wing_sessions`. (#1145, follow-up to #659)
- `mempalace_diary_read(wing="")` now returns diary entries from every wing this agent has written to, matching the #1097 "empty-string as no filter" pattern. Previously defaulted to `wing_<agent>`, siloing entries that hooks wrote to project-derived wings. (#1145)
- `mempalace mine` now skips the generated `entities.json` file so its contents aren't re-ingested as project content. (#1175)

### Improvements

- **Deterministic hook saves.** Save hook now uses a silent Python API path, so successive hook invocations produce reproducible results and zero data loss on the hot path. (#673)
- **Graph cache with write-invalidation** inside `build_graph()` — warm-path calls no longer rebuild the palace-graph per request. (#661)
- **`mempalace init` entity detection overhaul.** Canonical project names now come from package manifests (`package.json`, `pyproject.toml`, `Cargo.toml`, `go.mod`) and real people come from git commit authors, rather than being inferred from prose. Includes union-find dedup across name/email aliases, bot filtering that keeps `@users.noreply.github.com` humans, and automatic "mine" flagging by contribution share. (#1148)
- **Regex detector accuracy.** CamelCase extraction so `MemPalace`, `ChromaDB`, `OpenAI` aren't fragmented; tighter versioned/hyphenated pattern kills `context-manager` / `multi-word` false positives; dialogue `^NAME:\s` requires ≥2 hits so `Created: <date>` metadata stops classifying field names as people; expanded stopwords for common English participles and descriptors; high-pronoun signal classifies as person rather than dumping to uncertain. (#1148)
- **Init → miner wire-up.** Confirmed entities merge into `~/.mempalace/known_entities.json` on init, which the miner reads to tag drawer metadata for entity-filtered search. Previously init's output was not consumed by the miner; the per-project `entities.json` is kept as an audit trail. (#1157)
- **Case-insensitive project dedup** across manifest, git, and convo sources so casing variants of the same project name collapse into one review entry. (#1175)

### Added

- i18n: Belarusian translation. (#1051)
- i18n: entity detection for German, Spanish, and French locales. (#1001)
- i18n: Traditional + Simplified Chinese entity detection. (#945)
- **`mempalace init --llm`**: optional LLM-assisted entity classification. Defaults to local Ollama (zero-API); also supports any OpenAI-compatible endpoint (LM Studio, llama.cpp server, vLLM, OpenRouter, etc.) and the Anthropic Messages API. Runs interactively with a progress indicator; Ctrl-C cancels cleanly and returns partial results. Useful for prose-heavy folders where the regex detector struggles (diaries, transcripts, research notes). Opt-in only — default init path remains zero-API. (#1150)
- **Claude Code conversation scanner.** `~/.claude/projects/<slug>/` directories now contribute project entities using each session's authoritative `cwd` metadata, avoiding slug-decoding ambiguity. (#1150)

### Known — deferred to v3.3.4

- HNSW parallel-insert SIGSEGV when `hnsw:num_threads` is unset on collection creation (#974) — fix in-flight as #976, awaiting rebase against develop.
