Version bumps across pyproject.toml, mempalace/version.py, README badge,
uv.lock, and plugin manifests (.claude-plugin/*, .codex-plugin/*).
CHANGELOG aligned with main (post-3.3.1) and a new [3.3.2] section added
covering the 11 PRs merged on develop since v3.3.1 — silent-transcript-drop
fix + tandem sweeper (#998), None-metadata guards (#999, #1013),
chromadb ≥1.5.4 for Py 3.13/3.14 (#1010), Windows Unicode (#681),
HNSW quarantine recovery (#1000), PID stacking guard (#1023), doc-path
cleanup (#996, #1012), and RFC 001/002 internal scaffolding (#995, #1014, #990).
The CLI help text and README told first-time users to mine from ~/chats/,
a path that doesn't exist on any machine. Real location where Claude
Code writes session JSONL is ~/.claude/projects/<escaped-project-path>/.
Updates three user-visible strings:
- mempalace/cli.py line 7 ("Two ways to ingest" block)
- mempalace/cli.py line 25 (Examples block)
- README.md line 58 (Quickstart)
Website guides (website/guide/mining.md, getting-started.md) still
reference ~/chats/ for ChatGPT/Slack export scenarios where that remains
a valid placeholder. Those can be a separate PR if the maintainers want
to tilt the website examples toward Claude Code specifically.
Fixes#996.
Addresses #875. The previous README was 755 lines mixing six purposes
(scam alert, hero, two mea-culpa notes, install guide, architecture
explainer, API reference, file map). Rework it as a pure entry point:
what MemPalace is, how to install, honest benchmark numbers, links to
the website for concept/architecture documentation.
Key content changes:
- Drop the "highest-scoring AI memory system ever benchmarked" framing.
- New tagline: "Local-first AI memory. Verbatim storage, pluggable
backend, 96.6% R@5 raw on LongMemEval — zero API calls." Avoids
naming a specific vector-store implementation since the backend is
pluggable (see mempalace/backends/base.py).
- Remove the cross-system comparison table. Retrieval recall (R@5)
and end-to-end QA accuracy are different metrics and are not
comparable; placing MemPalace's R@5 next to competitor QA accuracy
under a single column header was a category error.
- The "100%" LongMemEval headline is no longer the lead. The honest
held-out figure is 98.4% R@5 on 450 unseen questions. The rerank
pipeline reaches >=99% with any capable LLM (reproduced with
Claude Haiku, Sonnet, and minimax-m2.7 via Ollama) — pipeline-level,
not model-specific.
- Benchmark reproduction commands now reference the correct repo
(MemPalace/mempalace, not the defunct aya-thekeeper/mempal branch).
New file: docs/HISTORY.md as the canonical home for post-launch
corrections, public notices, and retractions. Contains verbatim:
- 2026-04-14 note on this rewrite (links to #875)
- 2026-04-11 impostor-domain notice (moved from README header)
- 2026-04-07 "A Note from Milla & Ben" (moved from README body)
README keeps a one-line scam-alert callout that links to
docs/HISTORY.md for the full timeline.
Replace the blanket ban on .tech/.io/.com domains with an allowlist
of real MemPalace surfaces (GitHub repo, PyPI, mempalaceofficial.com)
and call out mempalace.tech as the reported impostor. The blanket
.com ban would have flagged mempalaceofficial.com as fake once DNS
resolves (CNAME shipped in #877).
Also update the April 11 follow-up section to match so the two
notices no longer contradict each other.
Noticed a URL
```
hXXps://www.mempalace[.]tech/
```
Though the README currently warns, it is perhaps best to surface it at urgency level at the top of the README.
Prepare develop for the 3.3.0 release cycle.
Version bumps:
- mempalace/version.py: 3.2.0 -> 3.3.0
- pyproject.toml: 3.2.0 -> 3.3.0
- README.md: pyproject.toml label and shields.io badge
- uv.lock: mempalace 3.0.0 -> 3.3.0 (also fills in resolved dev/extras)
CHANGELOG.md:
- Close out the stale [Unreleased] section as [3.2.0] - 2026-04-12
(v3.2.0 was tagged on that date but the release flip was never made)
- Add a fresh [Unreleased] - v3.3.0 section covering the 49 commits
since v3.2.0: closet layer, BM25 hybrid search, entity metadata,
diary ingest, cross-wing tunnels, drawer-grep, offline fact checker,
LLM-based closet regen, hall detection, cosine-distance fix,
multi-agent locking, README audit, etc.
- Adopt Keep a Changelog + SemVer framing
- Add version compare reference links at the bottom
- Fix stale milla-jovovich/mempalace preamble URL to MemPalace/mempalace
* fix: README audit — match every claim to shipped code + add hall detection
TDD audit: wrote 42 tests verifying README claims against codebase.
Fixed all 7 failures:
1. Tool count: 19 → 29 (10 tools were undocumented)
2. Added tool table rows for tunnels, drawer management, system tools
3. Version badge: 3.1.0 → 3.2.0
4. dialect.py file reference: "30x lossless" → "AAAK index format for closet pointers"
5. Wake-up token cost: "~170 tokens" → "~600-900 tokens" (matches layers.py)
6. pyproject.toml version in project structure: v3.0.0 → v3.2.0
7. Hall detection: added detect_hall() to miner.py — drawers now tagged
with hall metadata so palace_graph.py can build hall connections
New code:
- miner.py: detect_hall() — keyword scoring against config hall_keywords,
writes hall field to every drawer's metadata
- tests/test_hall_detection.py — 12 TDD tests (written before code)
- tests/test_readme_claims.py — 42 TDD tests verifying README accuracy
859/859 tests pass.

* fix: resolve ruff lint — unused imports and variables
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* style: ruff format with CI-pinned 0.4.x
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: use conftest fixtures in hall tests for Windows compat
Windows CI fails with NotADirectoryError when ChromaDB tries to
write HNSW files in short-lived TemporaryDirectory. Use conftest
palace_path and tmp_dir fixtures instead — same pattern as all
other tests that touch ChromaDB.

* fix: address Igor's review — convo_miner halls, cached config, markdown typo
TDD: wrote tests for convo_miner hall metadata and config caching
BEFORE verifying the code changes.
1. README markdown typo: extra ** in wake-up token row (line 195)
2. convo_miner.py: added _detect_hall_cached() — conversation
drawers now get hall metadata (was missing, Igor caught it)
3. miner.py + convo_miner.py: cached hall_keywords at module level
so config.json isn't re-read per drawer during bulk mine
4. New tests: TestConvoMinerWritesHalls, TestDetectHallCaching
861/861 tests pass. ruff clean.

The community caught real problems within hours of launch. Addressing them
directly:
- Added prominent "A Note from Milla & Ben" section at top owning the issues
- Fixed AAAK section: removed "lossless" claim, removed bogus token example,
honest about lossy nature and 84.2% regression on LongMemEval
- Headline benchmark table: clearly labeled as "raw mode" (the 96.6% number)
- Removed misleading "100%" headline (still real but rerank pipeline not
in public scripts yet — addressing)
- Removed misleading "+34% palace boost" headline (it's metadata filtering,
real but not a novel mechanism)
- Marked Contradiction Detection as "experimental, not yet wired into KG ops"
- Closet legend now notes plain-text summaries in v3.0.0, AAAK closets coming
- Intro pillars rewritten honestly — raw verbatim is the win, AAAK is
experimental compression layer
Thank you to @panuhorsmalahti (#43), @lhl (#27), @gizmax (#39) and everyone
who filed issues in the first 48 hours. Brutal honest criticism is exactly
what makes open source work.
Add Milla's conversational explanation of the palace architecture
(wings → rooms → closets → drawers → halls → tunnels) as an
introductory section before the technical diagram.
