and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [0.12.0]

### Fixed

- **FTS5 returning 0 results for camelCase queries (#451).** Added `file` column to FTS5 virtual table (schema v6), `split_camel_case()` identifier decomposition, and OR query expansion. Searches like `findUser` now correctly match via `find OR user`.
- **Dead-code false positives on framework entry points (#452).** Added `FRAMEWORK_ENTRY_PREFIXES` with SQL LIKE pattern matching for common framework handlers (`handle_*`, `on_*`, `route_*`, etc.) — these are no longer flagged as dead code.
- **Symbol-level suppression markers (#452).** Symbols containing `// cora: keep` in their body are excluded from dead-code detection.
- **Sticky skip files on config change (#453).** Added `index_config_hash` column to projects table — when `.cora.yaml` changes, previously skipped files are re-evaluated instead of permanently skipped.

### Added

- **`entry_point_patterns` config field** — New field in `AnalysisConfig` and `.cora.yaml` `analysis` section. Custom list of glob patterns for framework-specific entry points beyond built-in defaults.
- **Schema migration v6** — Auto-migration: adds `index_config_hash` to projects, drops and recreates FTS5 with `file` column, rebuilds search index.
- **`index_project_with_skip()`** — Indexing now respects `index_skip_files` from config, skipping non-code files during symbol extraction.
- **`split_camel_case()`** — Decomposes `camelCaseIdentifiers` into individual tokens for FTS5 search (`camelCase` → `camel OR case`).
- **Enhanced `sanitize_fts_query()`** — Handles quoted phrases, trims whitespace, and escapes special FTS5 characters.
- **31 new unit tests** — Tests for camelCase splitting, FTS5 query expansion, glob matching, suppression markers, framework prefix detection, schema migration v6, and config hash invalidation.

### Changed

- **`should_skip_file()` rewritten** — Simplified glob matching with early exit for non-glob patterns, explicit `**/name` branch handling.
- **Governance documentation** — Added CONTRIBUTING.md, CODE_OF_CONDUCT.md, SECURITY.md, PR template, issue templates (bug report + feature request), and PR checks workflow (branch naming, conventional commits, PR description validation).

## [0.11.1]

### Fixed

- **Index scanner false positives on entry-point files.** Added `index_skip_files` glob patterns to `RulesConfig`. Common bundler config files (`vite.config.ts`, `webpack.config.*`) and app entry points (`src/main.ts`, `src/index.tsx`) are now skipped by default — reducing noise from imports used by bundlers, not code.
- **`cora scan` now includes index findings.** Fixed bug where `cora scan` did not wire index scanners (unused imports, dead code) — the scan command now runs `scan_project_index()` to produce deterministic findings alongside LLM analysis.
- **Error fallback preserves index findings.** When LLM review fails, the fallback path now includes all index-based findings instead of silently dropping them.

### Added

- **`index_skip_files` config field** — New field in `RulesConfig` and `.cora.yaml` `rules_engine` section. Supports simple glob patterns (`*.config.ts`, `vite.config.*`, `**/main.ts`). Configurable per-project.
- **`should_skip_file()` helper** — Glob matching utility for index scanner file filtering.
- **8 new unit tests** — Tests for `should_skip_file()` covering exact match, wildcard suffix/prefix, `**/` patterns, and default skip list validation.

## [0.11.0]

### Highlights

- **Index-powered unused import detection.** `cora review` now flags unused imports using symbol graph analysis — not regex guessing. Detects imports that are never referenced in the file, across Rust, TypeScript, Go, and Python.
- **Dead code in review.** Changed files with dead functions/methods (zero callers) are now flagged automatically during review, not just via standalone `cora dead-code`.
- **Breaking change detection.** When a public symbol is removed or modified, review flags it with a list of affected callers — prevents silent breaking API changes.
- **HTTP route detection.** Route handlers (Axum, Actix, Express, Go net/http) are now tracked as first-class graph edges (`ROUTE`), enabling `cora query` to trace routes to handlers.
- **Brain enrichment (Tier 1).** Review pipeline now leverages symbol index for caller resolution, impact analysis, affected tests, and semantic search. Zero regression without index — falls back to regex-based resolution.

### Added

- **Unused import scanner** — `find_unused_imports()` in graph module, wired into review pipeline. Flags unused imports with file:line and imported symbol name.
- **Dead code scanner** — `find_dead_code_in_file()` in graph module. Detects unreachable symbols in changed files during review.
- **Breaking change scanner** — Detects removed public symbols and cross-references callers from index.
- **`EdgeKind::Route`** — New edge type for HTTP route → handler relationships.
- **Route extraction** — Axum `#[get("/path")]`, Actix `#[route("/path")]`, Express `app.get()`, Go `http.HandleFunc()`.

### Changed

- **Caller resolution** — Index-aware `resolve_callers()` uses graph query first, regex fallback only when no index.
- **Pre-commit hook** — Auto-runs `cora index --quiet` before review for persistent local index.
- **Context enrichment** — Impact analysis, affected tests, and brain search injected into LLM review prompt.
- **Ruby AST extraction** — Fixed `body_statement` wrapper bug in class/module method extraction.

### Technical

- **Resolved `test_extract_ruby`** — tree-sitter Ruby method extraction now correctly handles `body_statement` intermediate nodes.
- **CI 10/10 green** — All checks pass including format, clippy, test, build, security audit.

## [0.10.0] - 2026-07-29

### Highlights

- **Dead code detection.** `cora dead-code` finds functions/methods with no callers using call graph analysis. Available as both CLI command and MCP tool (`cora.dead_code`).
- **Graph query DSL.** `cora query "main -> *"` lets you traverse the code graph with simple patterns — no SQL needed. Available as both CLI and MCP (`cora.query`).
- **Auto-config agent installer.** `cora install` detects installed AI coding agents (Cline, Cursor, Windsurf, etc.) and configures Cora as their MCP server. One command setup.
- **Background reindex on serve.** `cora serve` now auto-reindexes the current project before starting the MCP server — always up-to-date symbols.
- **Tree-sitter is now a default feature.** The `edges` table (IMPORTS, IMPLEMENTS, INHERITS, CHILD_OF) now populates correctly in all builds, including release binaries.

### Added

- **`cora dead-code` CLI command** (#427). Detect dead functions/methods with `--include-tests`, `--min-lines`, and `--json` flags.
- **`cora.dead_code` MCP tool** (#428). Same dead code detection, accessible via Model Context Protocol.
- **`cora query` CLI command** (#435). Simple graph traversal DSL: `"symbol -> *"` (callees), `"* -> symbol"` (callers), `"SymbolName"` (symbol lookup).
- **`cora.query` MCP tool** (#435). Same query DSL via MCP.
- **`cora install` CLI command** (#431). Auto-detect 40+ AI coding agents and configure Cora MCP with one command. Supports `--list`, `--dry-run`, `--agents`, `--force`.
- **`cora.install` MCP tool** (#431). Same install detection via MCP.
- **`cora serve` with auto-reindex** (#434). `cora serve` runs incremental reindex on startup before launching MCP server.
- **Agent config module** (#432). Read/write support for JSON, JSONC, and YAML agent configuration files.

### Changed

- **Tree-sitter is now a default feature** (#429). `default = ["tree-sitter"]` in Cargo.toml. All builds (including release) now include AST-based extraction.
- **Release workflow** explicitly builds with `--features tree-sitter`.
- **CI workflow** explicitly builds/tests with `--features tree-sitter`.
- **MCP tool count** increased from 16 to 18 tools.

### Fixed

- **`edges` table was always empty** (#429). Root cause: tree-sitter feature was not enabled by default, so AST extraction (which produces IMPORTS, IMPLEMENTS, INHERITS, CHILD_OF edges) was never compiled into release binaries. Now fixed — 352+ edges populated on rebuild.

## [0.9.0] - 2026-07-28

### Highlights

- **Single source of truth.** Review findings, scan findings, and tech debt snapshots now persist to `cora.db` — one global database, no more scattered file snapshots.
- **Massive indexing speedup.** Rayon-parallel extraction + embedding, batch SQLite writes, PRAGMA tuning, and mtime:size fingerprinting deliver **52× faster incremental indexing** (414ms → 6ms) and **1.3× faster cold rebuild** (1,260ms → 936ms).
- **`cora findings` CLI.** Track, filter, dismiss, and reopen findings across all your reviews.

### Added

- **Persist review & scan findings to `cora.db`** (#397, #398). `cora review` and `cora scan` now save findings (severity, file, line, title, fingerprint) to the global database. Best-effort logging — never blocks the review pipeline on DB errors.
- **Auto-resolve stale findings** (#399). When a new review/scan completes, findings from prior reviews that no longer appear are automatically marked `resolved` with an `auto_resolved` event. Findings that reappear stay `open`.
- **`cora findings` CLI command** (#400). New subcommand with four actions:
  - `cora findings list` — show open findings (use `--all`, `--severity`, `--file`, `--json` for filtering)
  - `cora findings stats` — summary counts with resolution rate (`--json` supported)
  - `cora findings dismiss <id>` — mark as won't-fix with optional `--reason`
  - `cora findings reopen <id>` — reopen a dismissed/resolved finding
- **Migration v5 schema** (#396). New tables: `reviews`, `findings`, `finding_events`. Auto-migrates on first run.
- **`cora index --rebuild` flag.** Drop and re-index from scratch — useful for schema upgrades or corrupted indices.
- **Rayon parallel processing** (#409, #422). File extraction and embedding computation now run in parallel across CPU cores via Rayon.
- **Cache vector index in memory** (#407). `VECTOR_CACHE` (LazyLock) keeps the usearch HNSW index hot in memory — eliminates file I/O on every brain search.
- **Batch symbol lookup in RRF fusion** (#410). Brain search now batches DB lookups instead of per-result queries.
- **SQLite PRAGMA tuning** (#406). `journal_mode=WAL`, `synchronous=NORMAL`, `mmap_size=256MB`, `cache_size=-64MB` for faster writes.
- **Batch INSERT via multi-row VALUES** (#405). Symbol insertion now uses multi-row `INSERT ... VALUES (?,?,?),(?,?,?),...` instead of per-row inserts.
- **Batch transaction for `index_project`** (#404). All symbol/edge insertions wrapped in a single `BEGIN IMMEDIATE ... COMMIT`.
- **Disable FTS5 triggers during bulk indexing** (#411). Triggers re-enabled after commit — avoids redundant index updates mid-batch.
- **Mtime:size fingerprinting.** Replaces SHA256 content hashing for change detection. Trade-off: `--rebuild` available for full re-validation.

### Changed

- **`cora debt` reads from `cora.db` as primary source** (#403). File snapshots are now fallback only. DB is the single source of truth for tech debt reports.
- **`graph.db` renamed to `cora.db`** (#395). Auto-migrates existing `graph.db` on first run.
- `db_writer` module now exposes `open_db_for_read()`, `open_db_for_write()`, and `compute_fingerprint_pub()` for use by the findings CLI.

### Performance

Benchmarked on the cora-code repository (1,864 symbols, 115 Rust files, x86_64):

| Operation | Before (v0.8.3) | After (v0.9.0) | Speedup |
|-----------|-----------------|-----------------|---------|
| Cold index (full rebuild) | ~1,260ms | ~936ms | 1.3× |
| Incremental (no changes) | ~414ms | ~6ms | **52×** |
| Brain search (hybrid) | ~250ms | ~5ms | **40×** |

### Fixed

- **`cora brain` vector search filtered by project_id** (#382). Over-fetches from global usearch index, filters at DB layer — prevents cross-project noise.
- **Project root detection** (#380). Walks up from CWD to find `.cora.yaml` / `Cargo.toml` / `.git` instead of always using CWD.

## [0.8.3] - 2026-07-27

### Added

- **Svelte AST symbol indexing.** `cora index` with `--features tree-sitter` now extracts functions, arrow functions, and types from `<script>` blocks in `.svelte` files. Uses TypeScript/JavaScript grammar delegation — zero new dependencies. Supports `lang="ts"` and `lang="js"` attributes with correct line number offsets. Closes #384.
- **TypeScript arrow function extraction.** `export const handler = () => {}` and `const cb = function() {}` are now captured as symbols with call edges. Previously only ALL_CAPS constants were indexed from `lexical_declaration`/`variable_declaration` nodes.

### Fixed

- **Project root detection for scoped queries** (#380, #382). `resolve_project_root()` now walks up from CWD to find `.cora.yaml`, `Cargo.toml`, or `.git` instead of always using CWD. Fixes `cora brain` and `cora callers` returning results from wrong projects.
- **Vector search filtered by project_id** (#382). `brain_search()` now over-fetches from the global usearch index and filters by project_id at the DB layer, preventing cross-project noise in results.
- **Cross-project fallback for `cora callers`** (#381). When a symbol has no callers in the current project, falls back to searching across all projects in the global index.
- **Partial JSON recovery for scan results** (#383). `extract_partial_json_objects()` added as last-resort fallback when LLM returns truncated JSON arrays in scan output.

## [0.8.2] - 2026-07-25

### Added

- **8 additional tree-sitter languages.** Added AST extraction for C, C++, C#, Ruby, PHP, Scala, and JavaScript. Total tree-sitter supported languages: 12.
- **Dart symbol indexing.** `cora index` now extracts classes, mixins, enums, extensions, functions, getters, and typedefs from `.dart` files. Closes #373.
- **Svelte symbol indexing (regex).** Initial Svelte support via regex-based extraction — components (from filename), props, `$state`, `$derived`, functions. Closes #375. (Replaced by AST extraction in v0.8.3.)

## [0.8.1] - 2026-07-24

### Fixed

- crates.io publish (503 transient on v0.8.0)


## [0.8.0] - 2026-07-24

### Highlights

- **Brain Mode — hybrid code search.** `cora brain <query>` combines FTS5 keyword search, usearch vector similarity (HNSW), and graph BFS proximity into a single ranked result set via RRF fusion (k=60). Index-time embeddings use a zero-dependency static token method (256d) — no model download, no GPU.
- **tree-sitter AST extraction + call edges.** Schema v3 adds an `edges` table storing caller→callee relationships. When `cora index` runs with `--features tree-sitter`, it extracts function calls from AST nodes, enabling `cora trace` and `cora arch`.
- **`cora trace` and `cora arch` commands.** Trace symbol call chains (depth-limited) and display architecture overview (module breakdown, edge types, top connectors) from the indexed call graph.
- **Static token embedding engine.** Zero-dependency bag-of-tokens hashing (256d) for code symbol embeddings — suitable for near-duplicate detection and semantic search without external models.
- **Global index directory.** The symbol database migrated from `.cora/graph.db` (per-project) to `~/.codecora/cora-code/graph.db` (per-user), shared across all projects.
- **Renamed `cora-cli` → `cora-code`.** Binary is now `cora`, crate is `cora-code`.

### Added

- **Phase 3 — Brain Mode** (#362)
  - `CodeVectorIndex` — persistent usearch HNSW vector index with fs2 file locking, key↔symbol mapping, and disk serialization
  - `brain_search()` — hybrid search: FTS5 + usearch KNN (cosine, top-50) + graph BFS (depth-2 from FTS hits) → RRF k=60 fusion
  - Schema v4: `embedding_tier`, `embedding_dims`, `embedding_model`, `last_embedded_at` columns on `projects` table
  - Index-time embedding: all symbols embedded via static tokens during `cora index`
  - CLI: `cora brain <query> [--json] [--limit N]`
  - MCP tool: `cora.brain_search` — semantic code search for AI coding agents
- **Phase 2C — `cora trace` and `cora arch`** (#358)
  - `cora trace <symbol>` — trace call chains from a symbol (depth-limited BFS on call edges)
  - `cora arch` — architecture overview: module breakdown, edge types, top connectors
- **Phase 2 — tree-sitter AST extraction + Schema v3** (#356)
  - tree-sitter AST node extraction for Rust, Python, JavaScript, TypeScript, Go, Java
  - Schema v3: `edges` table (caller_id, callee_id, edge_type) storing call relationships
  - Gated behind `--features tree-sitter` (default build does not include tree-sitter)
- **Phase 1 — Static token embedding engine** (#354)
  - Bag-of-tokens hashing: 256d vectors from code text, zero external dependencies
  - Pre-trained nomic-embed-code vocabulary included (768d, reserved for Phase 5)
  - `tokenize_code()`, `embed_code()`, `cosine_similarity()` public API
- **Global index migration** (#355)
  - Symbol database moved from `.cora/graph.db` to `~/.codecora/cora-code/graph.db`
  - `CODECORA_HOME` env var override for custom data directory
- **Binary rename** (#338)
  - Crate renamed `cora-cli` → `cora-code`
  - Binary name: `cora`

### Changed

- **Docs website** — adopted `@codecora/theme` + VitePress base `/cora/docs/`, retired standalone LandingPage (#348)
- **Uteke memory integration** — removed from user-facing docs (implementation exists but undocumented until API stabilizes) (#367)

### Fixed

- **False positives suppressed in `sec-hardcoded-url` and `crypto/hardcoded-secret` rules** (#369, closes #357, #364)
  - `post_match_filter()` added to `builtin.rs` — filters matches in XML/SVG `xmlns` attributes, Rust docstrings, config files, and bare identifiers
  - Integrated into `security_scanner.rs` scan loop — all security scanner matches now pass through `post_match_filter`
  - Docker hostname regex (`DOCKER_HOST_RE`) fixed — `\d+` now correctly matches port digits
  - 31 targeted unit tests added for false positive suppression
- **CI clippy lints** — `map_or(false, ...) → idiomatic `is_some_and(...)` (#369)

### Stats

- 56 files changed, +46,948 / -2,050 lines since v0.7.0
- 11 PRs merged

## [0.7.0] - 2026-07-16

### Highlights

- **Deeper, token-economical cross-file review.** Reviews now resolve **who calls the changed code** (inbound / blast-radius), not just what the changed code calls — so breaking signature/type changes can be flagged. Bounded scanning + thin slices + a signature-only budget fallback keep token cost low.
- **Config is now validated at load time.** Out-of-range values (e.g. `temperature: 5`) and misspelled keys (`quailty_gate`) fail loudly instead of being silently ignored.
- **Markdown false positives suppressed.** Findings inside fenced code blocks (a `git push` in a fenced `bash` block flagged as SQL injection) are now dropped across all finding sources.
- **Performance, security, and correctness fixes** across the scan/review pipeline (10 perf bottlenecks, 2 CVE bumps, 8+ silent-corruption and best-practice bugs).

### Added

- **Inbound caller (blast-radius) resolution.** A new context-chain phase resolves call-sites of functions/types defined or modified in the diff, so breaking changes to their signatures surface their consumers. Gated by new `review.context_chain.include_callers` (default `true`); uses gitignore-aware walking and is bounded (≤400 files, ≤3 call-sites/symbol), injecting only the call line + 1 line of context. New `ContextPriority::CallerSite`.
- **Definition extraction** (`extract_definitions_from_diff`) for Rust/Python/JS-TS/Go/Java-Kotlin — detects functions/types *declared* in the diff, feeding caller resolution. Rust `mod foo;` and Java `import com.example.*` wildcards are now extracted correctly (#73, #72).
- **Signature-only budget fallback.** When the token budget can't fit a full function/type body, a thin signature slice (up to `{`) is injected instead of skipping the entry entirely (~3–5× more symbols under the same budget).
- **`Config::validate()`** (#94) — rejects out-of-range/unsupported values at load: `temperature` (0.0–2.0), `max_tokens`/`timeout` (≥1), `max_tokens_param`, `response_format`, `output.format`, `hook.mode`/`on_violation`/`min_severity`, and `provider.base_url` scheme. Multiple errors are aggregated into one message.
- **`Profile::validate()`** (#81) — focus `weight` must be 1–10, and `action`/`tone`/`detail_level` must be recognized values.
- **`deny_unknown_fields`** on all config sections (#80) — misspelled YAML keys are rejected at parse time.

### Changed

- **`CategoryAction` enum** (#57) — `quality_gate.categories.*.action` is now a case-insensitive enum (`block`/`warn`/`ignore`); a typo like `blok` fails loudly at config load instead of silently becoming blocking.
- **Disabled quality gate never fails** (#58) — `evaluate()` forces `Pass` when `enabled: false`.
- **`context_chain.max_context_tokens` default** raised 3000 → **5000**.
- **`issue_type`** serializes consistently as `issue_type` (#48); `type` retained as a deserialize alias.
- **`Severity::from_str_lossy`** uses `eq_ignore_ascii_case` (no allocation) (#10).

### Fixed

- **Markdown fenced-code-block false positives** (#329) — findings inside fenced code blocks (triple-backtick / triple-tilde) in `.md`/`.mdx`/`.markdown` files are dropped across all finding sources (security/secrets/rules scanners + LLM). Fence state is tracked across full hunk context, so it works even when only the block body was edited.
- **Cross-file resolver used the wrong ignore list** — `review.rs` passed `ignore.rules` (finding-type strings) instead of `ignore.files` (`target/**`, `node_modules/**`); the resolver could inject build-artifact code. Now uses `ignore.files`.
- **Test-file detection over-match** (#87) — `is_test_file` is path-segment aware; `latest`, `aspect`, `attestation` are no longer mistaken for test files.
- **Directory glob excludes over-permissive** (#66) — `src/` matches only at segment boundaries (`mysrc/` no longer caught).
- **Token estimation** (#68) — non-empty content returns ≥1 token (was 0 under integer division).
- **DB size** (#23) — `index_stats` queries `PRAGMA page_size` instead of assuming 4096 bytes.
- **Project-sync workflow** — a merged PR referencing issues via `Refs #N` (not `Closes #N`) no longer fails the `sync` check.
- **10 scan/review performance bottlenecks** (#335) — precompiled regex, batched DB queries, early cutoffs, file-content cache, single reused Tokio runtime, single-transaction prune, etc.
- **Security:** bumped `anyhow` 1.0.102 → 1.0.103 (RUSTSEC-2026-0190) and `crossbeam-epoch` 0.9.18 → 0.9.20 (RUSTSEC-2026-0204).
- Various silent-data-corruption bugs resolved (#333): severity sort, security-findings fallback, deterministic debt-snapshot hashing, debt-trend math, config precedence, `context_chain` merge, and hook-install composition.

## [0.6.2] - 2026-06-21

### Fixed — Token Usage Tracking

- **`tokens_used` is no longer always `None` in review and scan responses.**
  - `parse_review_response` and `parse_scan_response` previously discarded the `usage` object returned by the LLM API, hardcoding `Ok((..., None))`. Token counts and cost estimates were silently dropped.
  - `chat_completion` now returns `(content, Option<Usage>)` and the parse functions thread `usage` through as `TokenUsage`. All call sites updated.
  - `ReviewResponse.tokens_used` and `ScanResponse.tokens_used` now report real values when the provider supplies them.

- **`cora review --stream` now collects token usage.**
  - The streaming path (`chat_completion_stream`) previously only accumulated `delta.content` and ignored the `usage` field. It now sends `stream_options: { include_usage: true }` and parses `usage` from the final SSE chunk (top-level or nested in `choices[0].delta.usage`).
  - Token counts are now reported correctly for both streaming and non-streaming review.

- **`cora scan` multi-batch token accumulation.**
  - When scanning multiple batches, `total_tokens` was overwritten by each batch instead of accumulated. Only the last successful batch's tokens were reported.
  - Token usage now accumulates across all batches (`input_tokens`, `output_tokens`, and `estimated_cost_usd` are summed).

### Changed — Code Quality

- **Extracted magic numbers into named constants.**
  - `scan.rs`: the hardcoded batch size fallback `20` and token budget `60_000` are now `DEFAULT_MAX_FILES_PER_BATCH` and `DEFAULT_BATCH_TOKEN_BUDGET`.
- **`Usage` struct now accepts camelCase aliases.**
  - Some providers (e.g. Azure OpenAI, certain third-party gateways) return `promptTokens` / `completionTokens` / `totalTokens` instead of snake_case. Both forms are now accepted via `#[serde(alias = ...)]`.

### Tests

- Added 4 regression tests for token usage threading: `parse_review_preserves_usage_when_provided`, `parse_review_returns_none_usage_when_not_provided`, `parse_scan_preserves_usage_when_provided`, `usage_to_token_usage_maps_fields_correctly`.

## [0.6.1] - 2026-06-17

### Fixed — Scan

- **`cora scan` no longer aborts on non-JSON LLM responses (#316)**
  - Detect non-JSON responses early (provider error pages, rate-limit bodies, empty responses, prose wrappers) and surface the raw response prefix (first 512 bytes) in the error message so users can diagnose the cause.
  - Per-batch parse failures are now **non-fatal by default**: the failing batch is skipped with a `warn`-level log and a stderr warning listing the affected files, and the scan continues with the remaining batches. Set `--no-continue-on-batch-error` to restore the old abort behavior.
  - Added `--batch-files <N>` flag (default: 20) to control the maximum number of files per LLM batch — lower it to work around provider token limits or rate-limit errors on large scans.
  - Truncated-JSON and general parse errors now include the raw response prefix for easier debugging without `--verbose`.

### Fixed — Review

- **`cora review` no longer exits 2 when severity filtering removes all blocking findings (#312)**
  - Recompute `should_block` against the **filtered** issue list (after `--severity` filtering) so the exit code matches the SARIF/pretty output the user sees.
  - Extracted exit-code logic into `compute_exit_code()` helper (pure function) with 8 unit tests covering gate pass/fail, CI mode, and hook `block` vs non-`block` modes.
  - Applies to both the single-chunk and auto-chunked (`--auto-chunk`) review paths.

### Fixed — Install (macOS)

- **macOS installer now strips Gatekeeper quarantine attributes (#313)**
  - Prebuilt macOS binaries (`aarch64-apple-darwin`) are not Apple-notarized. When downloaded directly, macOS attaches `com.apple.quarantine` / `com.apple.provenance` xattrs and kills the binary with `Killed: 9` on first launch.
  - `install.sh` now runs `xattr -dr` for both attributes on the installed binary on macOS (best-effort, non-fatal).
  - Added a prominent `<details>` block in the README install section explaining the symptom, the manual `xattr` workaround for users who download the binary directly, and the `cargo` / Homebrew alternatives.

### Changed — Docs

- **Install section now warns about multiple distribution channels (#314)**
  - Recommends a single install method per platform and lists the supported channels (installer script, `cargo`, pre-built binaries).
  - Adds a `which -a cora && cora --version` check snippet and guidance for removing stale copies when more than one `cora` is on `PATH` (e.g. `~/.local/bin` vs `~/.cargo/bin` vs npm global).
  - Cross-links the original issue for background.

- **Uteke recall JSON parser** — handle both bare `[]` and wrapped `{"results":[]}` formats (uteke v0.1.0+)
- Extracted `parse_recall_json()` with 6 unit tests for format compatibility

## [0.5.0] - 2026-06-10

### Added

- **Improved review prompt** — better consistency, lower false-negative rate, explicit error handling focus area
- **Comprehensive docs/examples.md** — GitHub Actions section with setup guide, inputs reference, and provider table

### Changed

- **CI action moved to GitHub Marketplace** — workflow uses marketplace action instead of `.github/actions/cora-review/`
- **README links** — all documentation links now point to `codecora.dev` instead of relative file paths
- **CI workflows** — removed stale SvelteKit `website/` jobs, replaced with VitePress `docs/` build
- **`merge_into()` returns `Result`** — fail-fast on invalid profile config instead of silently continuing
- **Language context reuses parsed diff** — `build_language_context_from_chunks()` eliminates redundant `parse_diff()` call
- **13 stale issues closed** — migration epics, website tasks, v0.4 leftovers
- **15 stale branches deleted** — cleanup after merge

### Fixed

- **Profiles bugs** — path resolution with project root, fail-fast on invalid config, dedup merge by `id` (#238)
- **Code Scanning alert #79** — eliminated redundant `parse_diff()` call in language context injection
- **Download hardening** — 5x retry with exponential backoff, gzip validation, checksum verification for cora-code binary download in CI (#221)

## [0.4.6] - 2026-06-07

### Changed

- **README redesigned** — 568 → 148 lines, professional layout with star badge, docs index table, links to docs/ for details (#162)
- **All docs updated for v0.4.5+** — changelog, getting-started, usage, roadmap, examples, installation

### Added

- **Deterministic secrets pre-scan** — 12 built-in patterns (AWS, GitHub, OpenAI, Anthropic, Groq, xAI, Slack, Stripe, Google, JWT, Private Key) run before AI review (#204)
  - Masked output: `AKIA****CDEF` (first 4 + last 4 chars shown)
  - Auto-skip test/spec/fixture/mock/example files
  - Secrets findings injected into LLM context for consistent summary
  - Fallback path blocks on critical findings even when LLM fails
- **Diff parser hardening** — hunk line count validation, broader binary detection (GIT binary patch, singular form), graceful truncated diff handling (#195 Phase 1)
- **`.agent.md` release checklist** — pre-release checklist to prevent docs drift between versions

### Fixed

- `cora config show --global` / `--project` documented in cli-reference.md (was missing)
- `cora auth login` path corrected from `config.toml` to `auth.toml` in cli-reference.md
- CI example in docs now includes CORA_BASE_URL and CORA_MODEL secrets

## [0.4.5] - 2026-06-07

### Changed

- **Config architecture redesign** — clear separation of concerns between config files (#209)
  - `~/.cora/auth.toml` now stores **only the API key** (secret)
  - `~/.cora/config.yaml` stores provider, model, base_url, and other settings (global)
  - `.cora.yaml` (project) overrides global config per-project
  - `CORA_API_KEY` env var reserved for CI use only
- **Provider info auto-migration** — if `auth.toml` still contains provider/model/base_url, automatically moved to `config.yaml` on first run
- **Deterministic rules** — `rules/` added to default exclude paths, preventing rules from matching their own source definitions (#185)

### Fixed

- **`cora config show`** — now displays the **effective resolved config** with source annotations like `[from: env CORA_PROVIDER]` instead of raw file values (#189)
- **`cora config show --global`** — new flag to show only `~/.cora/config.yaml` contents
- **`cora config show --project`** — new flag to show only `.cora.yaml` contents (mutually exclusive with `--global`)
- **`cora review` sends to wrong provider** — provider info from `auth.toml`/`config.yaml` was ignored at runtime, always defaulting to OpenAI. Now correctly reads from merged config (#209)
- **`save_provider_info` data loss** — parse failure on `config.yaml` no longer silently replaces the entire file with defaults (now returns error)
- **`cora auth login` interactive flow** — now auto-detects provider env vars (e.g. pick ZAI → detects `ZAI_API_KEY`), suggests model and base URL defaults from presets (enter to accept) (#203)
- **`cora auth login --provider zai`** — now auto-detects `ZAI_API_KEY` from environment, no need for `--api-key` flag (#184)
- **Env var override visibility** — `cora config show` now annotates which values come from env vars vs config files (#182)
- **Truncated JSON repair tests** — 12 new tests confirming `repair_truncated_json()` works correctly for all edge cases (#186)

### Added

- **`--global` / `--project` flags** on `cora config show` for scoped config inspection
- **Clap `conflicts_with`** on `--global`/`--project` — `cora config show --global --project` now rejected at CLI level
- **Interactive model/base URL prompts** — during `cora auth login`, shows preset defaults and allows override with enter-to-accept

## [0.4.4] - 2026-06-06

### Fixed

- **Spinner auto-hides in non-TTY** — `indicatif` progress spinners in `llm.rs` and `scanner.rs` now detect piped/redirected stderr and auto-hide, preventing ANSI pollution in captured output (#181)
- **Truncated JSON repair** — LLM responses cut off by max_tokens are now auto-repaired by closing unclosed strings/brackets before parse, preserving partial findings instead of failing completely (#186)

### Added

- **`--output-file <PATH>` flag** — write formatted review output to a file instead of stdout, guaranteeing capture in CI/batch pipelines (#181)

## [0.4.3] - 2026-06-06

### Fixed

- **Provider shortcut now resolves preset defaults** — bare `provider: zai` in `.cora.yaml` auto-fills `base_url` and `model` from the preset table (#183)
- **Env var override warnings** — `CORA_PROVIDER`, `CORA_MODEL`, `CORA_BASE_URL` now warn when they override config file settings (#182)
- **`config show` displays effective (resolved) config** — shows actual runtime values with `[from: env ...]` annotations when env vars override config (#189)
- **Auth file permissions auto-fix** — `~/.cora/auth.toml` permissions auto-corrected to 600 instead of just warning (#187)
- **Deterministic rules exclude own source files** — security rules no longer match against `rules/` and `tests/` directories, eliminating false positives (#185)

### Added

- **Non-interactive `cora auth login`** — `--provider`, `--api-key`, `--model`, `--base-url`, `--force` flags for scriptable setup (#184)

## [0.4.2] - 2026-06-06

### Fixed

- **Cora Review now works on fork PRs** — changed trigger from `pull_request` to `pull_request_target` so `GITHUB_TOKEN` has write access for PR comments on external contributor PRs. Explicitly checks out PR head SHA for correct diff (#178 context)

### Added

- **Top-level provider shortcuts in `.cora.yaml`** — `model:`, `base_url:`, and bare `provider:` string now accepted at top level without needing nested `provider:` section (#178, closes #176)

## [0.4.1] - 2026-06-06

### Fixed

- **Regex panic on optional hunk groups** — bare hunk headers like `@@ -1 +1 @@` (without `,count`) caused `caps[4]` index-out-of-bounds panic. Now uses `caps.get(N)` with safe fallback (#167)
- **Default max_diff_size raised to 5MB** — 50KB was too small for most real PRs (#167)
- **CI action resilience** — 3× retry on cora review failure, 600s timeout, graceful SARIF fallback when LLM API is unavailable (#174)

### Added

- **`cora init` now installs pre-commit hook** — automatically creates `.git/hooks/pre-commit` alongside `.cora.yaml`. Use `--no-hook` to skip. Falls back gracefully when not in a git repo (#176)
- **Tiered `cora auth login`** — interactive provider selection with numbered menu. Known providers (openai, anthropic, groq, ollama, zai) pre-fill base URL and model. Custom providers ask for base URL + model + key (#172)
- **Configurable CI action** — reads `.cora.yaml` from repo when present, falls back to 5MB limit when absent. Removes hardcoded `max_diff_size: 200000` (#172)
- **`on_violation` config + `--ci` mode** — hard gate for CI: `on_violation: disallow` makes cora exit non-zero on any finding. `--ci` flag enables strict non-interactive mode (#152)
- **`cora hook install/uninstall`** — explicit hook management commands (previously only via `cora init`)

### Changed

- **CI action reads `.cora.yaml`** — project config takes precedence over hardcoded fallback. `max_diff_size`, `hook.mode`, `llm.timeout` all respected in CI (#172)

## [0.4.0] - 2026-06-03

### Added

- **Deterministic rule engine** — pre-LLM regex-based rules that always report findings (no LLM dismissal). 12 built-in rules covering security (hardcoded URLs, secrets, TLS disabled, debug prints), SQL injection, TODO/FIXME, `panic!`/`unwrap` in new code, and large functions (#116)
- **Custom rules via `.cora.yaml`** — define project-specific regex rules with severity, category, exclude patterns, and glob file matching
- **Unified diff parser** — parse git diff into structured `FileChunk`/`DiffHunk`/`DiffLine` with language detection for 70+ extensions
- **File bundling engine** — smart grouping by directory and language family with configurable character/file limits. Bundle types: related, config, test, large, standalone. Token budget estimation (~4 chars/token). Defers full parallel review to v0.5 (#115)
- **Cross-file context chain** — deterministic symbol extraction (imports, function calls, type references) for 5 languages (Rust, Python, JS, Go, Java) with token-budgeted context injection into LLM prompt (#114)
- **`BundlingConfig`** — `strategy`, `max_chars_per_group`, `max_files_per_group`, `coalesce_by_directory`, `coalesce_by_language` in `.cora.yaml`
- **`ContextConfig`** — `enabled`, `max_context_tokens`, `follow_depth`, `max_symbols` in `.cora.yaml` review section
- **Default SARIF upload to GitHub Code Scanning ON** — opt-out with `upload-sarif: false` (#148)
- **SARIF tool branding** — `CodeCora` driver name (`codecoradev/cora-code`) in SARIF output (#148)

### Changed

- **Review pipeline** — rules engine runs before LLM call, context chain enriches LLM prompt with cross-file dependencies
- **LLM failure handling** — deterministic rule findings always visible even when LLM call fails

## [0.3.0] - 2026-06-03

### Added

- **Static analysis context injection** — optional clippy output injected into review prompt to reduce false positives on verified-intentional changes (#140)
- **`review.static_analysis.auto_clippy`** config — automatically run `cargo clippy` and filter output to changed files
- **`review.static_analysis.clippy_output_file`** config — read pre-computed clippy output from file
- **`cora config validate`** subcommand — validate `.cora.yaml` configuration file and report issues (#88)
- **`CoraError` enum via thiserror** — structured error types for engine layer with 17 variants (#86)

### Changed

- **Engine layer migrated from `anyhow` to `thiserror`** — structured error handling in engine, `anyhow` retained in CLI layer (#86)
- **All clippy pedantic warnings resolved** — 175 → 0 warnings across entire codebase (#84)
- **Repo URLs updated** to `codecoradev/cora-code` org (#137)
- **CI actions bumped** — `upload-artifact@v7`, Node 24 strict mode (`FORCE_JAVASCRIPT_ACTIONS_TO_NODE24`) (#142)

### Fixed

- **CI Cora Review fails on LLM API errors** — removed `|| true` suppression, added exit code + empty SARIF check (#142)
- **Match arm merge in `IssueType::from_str`** — clarified documentation (#141)

## [0.2.0] - 2026-06-02

### Added

- **`--progress` flag** — NDJSON progress events to stderr for structured CI/GUI consumers (Termul prerequisite) (#108)
- **`--max-diff-size` flag** — override `hook.max_diff_size` for large diffs from CLI (#112)
- **Output footer watermark** — Cora version stamp in terminal, SARIF, and JSON output when issues found (#106)
- **Security audit CI** — `cargo audit` via `rustsec/audit-check` for dependency CVE scanning (#85)

### Changed

- **Naive .gitignore parser → `ignore` crate** — ripgrep-grade correctness with nested .gitignore, global gitignore, and `.git/info/exclude` support (#80)
- **Blanket `#![allow(dead_code)]` removed** — targeted cleanup, 27 warnings → 0 (#79)

### Fixed

- **`REQUESTS_CA_BUNDLE` env var support** — custom CA certificates for corporate proxies, additive to built-in root certs (#74)
- **`tls_built_in_root_certs(false)` security fix** — custom CA bundle now added alongside system roots instead of replacing them (caught by Cora self-review)
- **`require_git(false)` on WalkBuilder** — gitignore rules applied even outside git repositories (#112)
- **CI `actions-rs/audit-check` → `rustsec/audit-check`** — replaced archived GitHub Action (#112)
- **Cora CI diff limit** — `CORA_CONFIG` env var with temp config for 200K char limit in CI action (#112)

## [0.1.8] - 2026-06-02

### Fixed

- **`unwrap()` → `expect()`** in ProgressStyle templates (llm.rs, scanner.rs) — clearer panic messages on template parse failure (#87)
- **Consolidated duplicate `impl Severity` blocks** into single implementation (#83)
- **`file_content_hash` returns `Option<String>`** instead of empty string on read failure — prevents infinite rescan loop on unreadable files (#77)
- **Permission errors logged in scanner** — file walk now logs permission errors at debug level instead of silently skipping (#76)
- **Auth file permission warning** — warns if `~/.cora/auth.toml` has overly permissive file permissions (Unix only) (#72)
- **SARIF upload size validation** — validates SARIF file size against GitHub's 10MB limit before upload (#82)
- **Float division for MB display** — SARIF size error now shows accurate fractional MB (was integer division truncating to 0) (#82)
- **Non-deterministic `DefaultHasher` → `sha2`** — scan cache now uses SHA-256 for deterministic hashing across Rust versions (#81)

### Added

- **`checksums-sha256.txt` in release artifacts** — release workflow generates SHA-256 checksums for all platform binaries (#109)

### Changed

- **Official CodeCora branding assets** — logo, favicon, and OG image updated from ajianaz/cora SaaS repo (#110)
- **Standalone `cora-review.yml` workflow** — CI action extracted from inline `ci.yml` job to dedicated workflow with concurrency control (#107)
- **Action v2 hardened** — all third-party actions pinned to commit SHA, checksum verification for binary downloads, env var indirection for inputs, `grep` pipefail fix, empty file guard, Node 24 strict mode compatibility (#107)

## [0.1.7] - 2026-06-01

### Added

- **Diff-hash caching** — review results cached by SHA-256 of diff + model + temperature in `~/.cache/cora/reviews/`. Cache TTL configurable via `llm.cache_ttl` (#100)
- **`--no-cache` flag** — bypass cache for fresh reviews (#100)
- **Configurable LLM parameters** — `llm.temperature` (default: 0), `llm.max_tokens` (default: 4096), `llm.timeout` (default: 120s), `llm.cache_ttl` (default: 1440 min) in `.cora.yaml` (#98 #101)
- **Git ref validation** — rejects refs containing shell metacharacters or path traversal sequences (#73)

### Fixed

- **Temperature default now 0** — eliminates non-deterministic LLM output. Same diff produces identical issues on every run (#98, #97)
- **HTTP timeout actually works** — per-request timeout via reqwest RequestBuilder (not client-level). Configurable timeout respected (#99)
- **Connection pooling** — shared reqwest::Client via LazyLock, reused across all requests (#99)
- **Cache key includes model + temperature** — config changes invalidate cache automatically (#100)
- **Silent config corruption** — malformed `.cora.yaml` now shows clear error with file path and hint (#78)
- **Composite action KeyError on API failure** — version resolution retries 3x with 5s delay, falls back to v0.1.6 with warning. Fixed in both `cora-review` and `cora-review-simple` actions (#102)

## [0.1.6] - 2026-06-01

### Added

- **Custom system prompts via config** — `review.system_prompt`, `review.system_prompt_file`, `scan.system_prompt`, `scan.system_prompt_file` fields in `.cora.yaml` (#94)
- **`response_format` config** — opt-in `json_object` response format for providers that support it, via `review.response_format: json_object` (#92)
- **File path injection into prompts** — valid diff file paths are injected into the review user prompt to reduce LLM hallucination (#93)
- **Post-parse file path filtering** — issues referencing non-existent files are filtered out after LLM response parsing (#93)
- **Enhanced default system prompts** — both review and scan prompts now include explicit anti-hallucination constraints, severity definitions, and format instructions (#95)

### Fixed

- **Path traversal in `system_prompt_file`** — arbitrary file read vulnerability. Now validates file path is within canonicalized project root (#92)
- **Symlink bypass in path traversal guard** — project root is now canonicalized to match resolved file paths

## [0.1.5] - 2026-06-01

### Fixed

- **Critical: JSON repair corrupts valid unicode escapes** — `is_valid_json_escape()` missing `'u'`, causing `\uXXXX` to be double-escaped. Now properly validates and handles incomplete `\u` sequences (#89)
- **Critical: TOML injection in `save_api_key()`** — API key written via `format!` string interpolation. Now uses `toml::Table` serialization (#69)
- **Retry prompt improvement** — retry on parse failure now includes stricter JSON format instructions (#90)
- **Temp file race condition** — SARIF upload now uses PID-suffixed temp path instead of fixed filename (#70)
- **Confusing unused `_cli_api_key` parameter** — removed from `load_config()` signature (#75)

### Security

- `save_api_key()` now uses `toml::Table::insert()` instead of string interpolation (prevents TOML injection)
- Temp SARIF file path includes process ID (prevents TOCTOU race)

## [0.1.4] - 2026-06-01

### Added

- LLM JSON repair engine (`repair_invalid_escapes`) — auto-fixes invalid escape sequences in LLM output (e.g. `\s`, `\d`) before JSON parse
- Retry mechanism in `review_diff` — if first LLM parse fails, automatically retries once
- Branding footer on "No issues found" PR comment — consistent with issues-found variant

### Fixed

- **Silent false-negative** — cora JSON parse failure previously posted "No issues found" without actual review (LLM invalid escapes)
- Hardcoded Infisical `identity-id` in `release.yml` and `deploy-website.yml` — migrated to `secrets.INFISICAL_IDENTITY_ID`
- Release workflow changelog extraction — `v` prefix mismatch (tag `v0.1.3` vs CHANGELOG `[0.1.3]`) now properly stripped
- `printf` double-escape in release workflow — `\\n` corrected to `\n`
- Stale `v0.1.2` binary download filenames in README
- Clippy `unnecessary_map_or` lint — `.map_or(false, |s| s.success())` replaced with `.is_ok_and(|s| s.success())`

### Changed

- All 3 workflows use `secrets.INFISICAL_IDENTITY_ID` (consistent with `ci.yml` pattern)
- Release workflow validates semver format before sed injection
- Branch cleanup — removed 14 stale branches

## [0.1.3] - 2026-06-01

### Added

- `cora config set --global` — write config to `~/.cora/config.yaml` instead of project `.cora.yaml`
- `cora config set base_url` — set base URL via CLI (previously only in YAML)
- Global config support (`~/.cora/config.yaml`) with priority chain: CLI flags → env vars → project → global → defaults
- Auto-migration from old `~/.cora/config.toml` to new YAML + `auth.toml` split

### Changed

- `cora config set` now writes YAML instead of TOML (compatible with config loader)
- API key storage moved from `~/.cora/config.toml` to `~/.cora/auth.toml` (0600 permissions)
- YAML serialization uses `skip_serializing_if` — no more `null` values in output

### Fixed

- **Severity comparison inverted** — `Critical` issues no longer silently pass `should_block` check (Ord ordering bug)
- Hook `mode: block` no longer exits with code 2 when "No issues found" (severity filter mismatch)
- Consistent severity logic across review, scan, and block mode paths

## [0.1.2] - 2025-05-29

### Added

- `cora init` — create `.cora.yaml` config file with provider/model selection
- `cora hook install|uninstall` — pre-commit hook management
- `cora config show|set` — configuration management
- CI composite action (`cora-review-simple`) for easy GitHub Actions integration
- Shell completions for bash, zsh, fish, and powershell
- `cora scan --incremental` with SHA256 content hash cache for fast incremental scanning
- `cora review --upload` for direct SARIF upload to GitHub Code Scanning

- `cora review --base <branch>` for branch comparison
- `cora review --diff-file <path>` for reviewing external diff files
- `cora providers` command to list available LLM providers
- `cora auth login` for interactive API key storage

### Fixed

- SARIF schema compliance for GitHub Code Scanning upload
- Clippy `format_in_format_args` warnings
- Replaced deprecated `serde_yaml` with `serde_yaml_ng`
- Normalized release binary naming (`cora-{arch}-{target}-v{version}.tar.gz`)

### Changed

- Replaced deprecated dependencies
- Removed unused dependencies
- Bumped minimum Rust version to 1.85

## [0.1.1] - 2025-05-27

### Changed

- Replaced ASCII art banner with eye icon in README
