 ## Unreleased
 
+## v0.2.2 (2026-07-21)
+
+LadybugDB graph engine migration — all graph queries now go through LadybugDB Cypher, with `entity`/`relation` as the canonical source tables. `graph_nodes`/`graph_edges` are deprecated. Plus `enhance_project` now populates the full model layer even on already-finalized projects.
+
+### 🚀 New Features
+
+- **LadybugDB Graph Engine Migration**: All graph query tools (`find_callers`, `find_callees`, `get_neighbors`, `get_subgraph`, `graph_query`, `shortest_path`, `get_graph_stats`, `get_entry_points`, `find_definition`, `find_references`) now go through LadybugDB Cypher exclusively. SQLite `graph_nodes`/`graph_edges` fallback removed. Results served from KuzuDB property graph (`(:Entity)-[:RELATES]->(:Entity)`).
+- **`buildLadybugFromEntityRelation`**: New function that builds LadybugDB directly from `entity`/`relation` tables via CSV + Kuzu COPY FROM. Replaces the old `compileGraphToLadybugDB` which read from `graph_nodes`/`graph_edges`. 579ms for 1,387 nodes + 2,885 relations on CodeScope self-index. Legacy fallback preserved for unit tests.
+- **`enhance_project` model build on finalized projects**: Fixed `engine_enhance_project` to run `runModelIndexSync` + `buildKnowledgeGraphSync` even when the project is already finalized. Previously returned early with `already_finalized` status, leaving `module_summary`, `modules`, `architecture_edge`, and `module_edge` tables empty. Now populates all model tables unconditionally.
+- **8-Layer Smart Filtering**: Comprehensive filter system documented in README — 8 layers covering any-depth skip dirs (~120 patterns), top-only skip dirs, suffix skip, filename skip, prefix skip, `.gitignore`, `.codescopeignore`, and file size + language detection.
+
+### 🐛 Bug Fixes
+
+- **`enhance_project` empty model tables**: When `index-parallel` ran with `CODESCOPE_SKIP_ASYNC=1`, `enhance_project` returned `already_finalized` without running the async knowledge builder. `module_summary`, `modules`, `architecture_edge`, and `module_edge` tables stayed empty. Fixed by adding a `run_model_build` goto label that runs `runModelIndexSync` + `buildKnowledgeGraphSync` even on finalized projects.
+- **`find_callers`/`find_callees` empty on re-indexed projects**: LadybugDB was not populated because `buildGraph` skipped LadybugDB init when `CODESCOPE_SKIP_ASYNC=1`. Fixed by `buildLadybugFromEntityRelation` being called from `buildGraph` unconditionally (when LadybugDB is initialized).
+- **`compileGraphToLadybugDB` error message stale**: Error message in `store_graph.cpp` still referenced `compileGraphToLadybugDB` after migration to `buildLadybugFromEntityRelation`.
+
+### 🔧 Improvements
+
+- **`buildLadybugFromEntityRelation` performance**: 579ms for 1,387 nodes + 2,885 relations on CodeScope self-index. LadybugDB file: 3.4MB vs SQLite 77MB (4.4%).
+- **`enhance_project` timing**: total 2,655ms (semantic_facts 175ms, buildGraph 579ms, runModelIndexSync 1,894ms, buildKnowledgeGraphSync 1ms).
+- **8-Layer Filtering**: Documented in README with real-world impact data (rustc: 36,919 → 6,029 files, 84% filtered).
+- **goagent CLOSURE_PLAN.md**: Comprehensive closure plan for goagent project — P0-P3 priority, orphan module analysis, evolution loop closure, stability hardening.
+
+### 🔒 Code Review Fixes
+
+- **Double-close file descriptor risk**: `writeEntityEdgeCsvs` and `compileGraphToLadybugDBLegacy` error handlers had double-close on file descriptors when `fdopen` succeeded for one temp file but failed for another. Fixed by negating fd variables after successful `fdopen`.
+- **Temp file leak on fdopen failure**: `writeEntityNodeCsv` and `writeEntityEdgeCsvs` did not `unlink` temp files when `fdopen` failed. Fixed by adding `unlink()` calls in error paths.
+
+### 📚 Documentation
+
+- **README.md / README.zh.md**: Added 8-Layer Smart Filtering section with real-world impact data (rustc, goagent, CodeScope, Linux kernel). Updated benchmark data tables.
+- **goagent CLOSURE_PLAN.md**: Written to goagent project root. 4-phase plan (P0 Agent core loop, P1 Evolution loop, P2 Island elimination, P3 Stability hardening). ~20 person-days estimate.
+- **Benchmark data updated**: Index time, node/edge counts, and file counts updated for all benchmarked projects. Added LadybugDB storage comparison.
+
+### 🧹 Chores
+
+- **Version bump**: 0.2.1 → 0.2.2
+- **`graph_nodes`/`graph_edges` deprecated**: Query tools no longer read from these tables. Tables still written for backward compatibility; will be removed in v0.3.
+
+---
+
 ## v0.2.1 (2026-07-19)
 
 Open-source release. Closes the gap between the Resolver Pipeline and the query/verify surfaces (call-graph `resolve_strategy` propagation, module-tree JSON validity, capability verifier LIKE-direction, module-hierarchy materialisation), plus FFI boundary detection, paginated graph export, LadybugDB embedded storage, one-click bootstrap, and a full code-review / portability / documentation pass.

-## 3. Quick Start
+## 3. 8-Layer Smart Filtering: Why Only 6,029 of 36,919 Files Are Indexed
+
+CodeScope does **not** index every file in a project. Instead, it applies an **8-layer cascade** that strips away noise so you only see what matters: the core source code.
+
+### The Problem
+
+A typical project looks like this (rustc, the Rust compiler):
+
+```
+Total source files:  36,919
+  tests/            26,293  ← 71%: test suites
+  src/tools/*/test/  3,802  ← 10%: embedded test directories
+  library/*/test/      339  ←  1%: library tests
+  compiler/*/test/     118  ← <1%: compiler tests
+  docs/vendor/bench/   368  ←  1%: documentation, vendored deps, benchmarks
+  ─────────────────────────────────────
+  Core code indexed: 6,029  ← 16%: the actual source code
+```
+
+Without filtering, CodeScope would waste 84% of its time indexing tests, vendored dependencies, documentation, and build artifacts — files no one needs to analyze.
+
+### The 8-Layer Filter Cascade
+
+```
+Layer 1: any-depth skip directories  (~120 patterns)
+  .git, .svn, .hg, node_modules, .venv, target, build, dist,
+  vendor, __pycache__, .github, deploy, docker, k8s, ...
+  → Catches VCS, build artifacts, dependencies, CI/CD, infra at ANY depth
+
+Layer 2: top-only skip directories  (depth ≤ 3, Java-safe)
+  test, tests, docs, examples, samples, scripts, e2e, integration,
+  assets, static, public, media, i18n, bench, benchmarks, ...
+  → For Java: protects package namespaces (org/.../samples/petclinic)
+
+Layer 3: file suffix skip  (always applied)
+  .md, .txt, .json, .yaml, .toml, .ini, .png, .jpg, .svg,
+  .pdf, .zip, .tar, .min.js, .d.ts, ...
+  → Non-source files, documentation, images, archives
+
+Layer 4: exact filename skip
+  package-lock.json, yarn.lock, .DS_Store, Thumbs.db,
+  .env, .env.local, .gitkeep, .gitignore, ...
+
+Layer 5: filename/directory prefix skip
+  File prefixes: ._*, ~$*, #*#
+  Directory prefixes: build_*, test_*, tmp_*
+
+Layer 6: .gitignore pattern matching
+  Respects every rule in the project's .gitignore
+
+Layer 7: .codescopeignore (user-defined)
+  Additional custom ignore patterns per project
+
+Layer 8: file size limit + language detection
+  • Max file size (default 10 MB, configurable via CODESCOPE_MAX_FILE_SIZE)
+  • Undetectable language files are silently skipped
+```
+

+
+### Override: `force_index_files`
+
+Need to index a specific test file or vendored directory? Use the `force_index_files` MCP tool — it **bypasses** all 8 layers:
+
+```bash
+codescope cli force_index_files '{"paths":["/path/to/test/file.rs"]}'

+### Evidence Pipeline (v0.3)
+
+The v0.3 Evidence Pipeline transforms indexed code into verifiable evidence and project health snapshots. Flow: `Facts → SemanticFacts → Evidence → Verification → ProjectState`. Semantic facts are extracted by `enhance_project` (Step 1.5); evidence is built by applying declarative rule files (`engine/src/evidence/rules/*.json`) to the semantic_fact table.
+
+| Tool | Description | Parameters |
+|------|-------------|------------|
+| `enhance_project` | Run background enhancement: full tree-sitter parse, call graph, metrics, FTS, and v0.3 semantic_fact extraction. Prerequisite for `build_evidence` to produce non-empty findings. | `{}` |
+| `build_evidence` | Build evidence findings by applying the rule set (sync/memory/error/pattern/framework/ffi) to the project's semantic_fact rows. Each rule declares fact needs + a combine mode (Collect / MissingMatch / MissingMatchPerFunction / Count). Returns a JSON array of Evidence objects. Run after `enhance_project` so semantic facts are populated. | `{"category": "string (optional, one of: sync|memory|error|pattern|framework|ffi)"}` |
+| `verify_statement` | Verify a natural-language claim against the project's indexed evidence. Pipeline: IntentParser → Planner → EvidenceBuilder → VerdictBuilder. Returns JSON with `verdict` (Supported\|Contradicted\|PartiallyVerified\|Unknown), `confidence`, `requirements[]`, and `evidence[]`. Use this for yes/no questions about code behavior (e.g. "does this project safely handle CString?"). | `{"claim": "string (required)"}` |
+| `build_project_state` | Build (or rebuild) and persist the project state snapshot. Runs the full v0.3 Evidence Pipeline (evidence aggregation + state queries) and UPSERTs the result into the `project_state` table. Returns the snapshot JSON: overall confidence, capability/architecture/workflow/dead_code scores, per-category issue counts, and `last_updated` timestamp. | `{}` |
+| `get_project_state` | Get the previously persisted project state snapshot (without rebuilding). Returns the `snapshot_json` string for the project, or a JSON error object if no snapshot exists yet (run `build_project_state` first). Use this for fast reads of the latest health snapshot. | `{}` |
