From f00682b2720ab9bfe50e2e8af013b8c632788901 Mon Sep 17 00:00:00 2001 From: "Anaz S. Aji" Date: Tue, 4 Aug 2026 13:07:56 +0700 Subject: [PATCH 01/18] docs: comprehensive documentation audit (#476) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * docs: comprehensive documentation audit — fill gaps, fix outdated info CLI Reference (docs/cli-reference.md): - Added 6 missing commands: dead-code, query, routes, serve, install, profile - Added missing flags across all commands (--memory, --learn, --stdin, --filter, --coalesce, etc.) Configuration (docs/configuration.md): - New section: Ignore Files (ignore.files) with full 7-pattern glob syntax table - New section: Static Analysis (review.static_analysis: auto_clippy, clippy_output_file) - New section: Bundling (max_chars_per_group, strategy, coalesce options) - New section: Analysis (entry_point_patterns) - MCP tools table expanded from 5 → 18 tools - Added cora serve (auto-reindex variant) alongside cora mcp - Improved .cora.yaml example to be more comprehensive Code Intelligence (docs/code-intelligence.md): - Schema version updated v4 → v6 (added v5: reviews/findings/finding_events, v6: index config hash) - New section: cora dead-code (dead code detection) - New section: cora query (code graph query patterns) - New section: cora routes (HTTP route listing) - Fixed: --test-glob → --filter (renamed flag) - Added --stdin to cora affected examples README.md: - Code Intelligence table: added dead-code, query, routes - Config & Setup table: added config validate, profile list, serve, install - MCP tools count: 15 → 18 docs/index.md: - MCP tools count: 15 → 18 * docs: fix wrong defaults and add missing fields from subagent audit Fixes identified by parallel subagent audit: - Profile names: strict/balanced/lax → actual 8 profiles (security-first, performance, clean-code, beginner-friendly, minimal, rust-strict, typescript-strict, go-pragmatic) - max_findings default: 50 → 5 - bundling.max_chars_per_group: 12000 → 60000 - bundling.strategy: directory → smart (actual enum: smart | flat) - --lang → --language in code-intelligence.md - +3 context_chain fields: use_brain, impact_depth, prefer_index -

Aji" Date: Tue, 4 Aug 2026 16:24:45 +0700 Subject: [PATCH 02/18] fix(config): merge ignore.files and index_skip_files instead of overwriting (#477) Config merge used clone_from/clone for ignore.files and index_skip_files, which silently overwrote default patterns when a user specified any custom value. This caused build artifacts (target/**, dist/**, node_modules/**, .git/**) and framework config files (*.config.ts, *.config.js) to leak into review context, scan walks, and index-based scanner output. Fix: extend defaults with user values instead of replacing, with deduplication to avoid redundant entries. Impact: - cora review: context_chain now correctly filters default-ignored paths - cora scan: walk_project exclude patterns now include defaults - cora index: index-based scanner skip files preserved - cora config show: effective config displays merged patterns Tests: 3 new tests (merge_ignore updated, dedup, index_skip_files). 776 unit + 22 integration tests pass. Clippy clean.

Neither matched — so uninstall would delete the cora hook WITHOUT restoring the user's original, losing it forever. Fix: install now writes 'pre-commit.pre-cora.bak' (matching what uninstall searches for), and the dead 'pre-commit.cora.bak' path in uninstall is removed. Added regression test that verifies backup filename consistency.

This triggered false positives on: - Env var names like TITEN_CORS_ORIGINS (contains 'cors' + '*' from markdown bold) - Documentation prose mentioning CORS configuration - Comments instructing developers NOT to use wildcards Three-layer fix: 1. Narrow regex to require actual code patterns: - Access-Control-Allow-Origin: * (HTTP header) - cors = * / allow_origin(*) / origin: * / allowed_origins = * - Method calls like .allow_origin(*) now matched via [=:(] delimiter 2. Skip non-code files (.md, .txt, .rst, .adoc, .tex, .org, etc.) Security patterns are designed for source code, not prose. 3. Post-match negation context filter: Suppresses matches in negation contexts like 'no wildcard', 'do not use *', 'without wildcard', and env var name patterns (cors_origins, cors_allowed, cors_config). Tests: 25 new test cases covering true positives, false positives from issue #483, doc file detection, and negation context suppression.

Also fixes: - Removed unsupported lookahead (?!\w) — Rust regex crate limitation - Negation filter skips suppression when comment has code indicators - cors_config suppression scoped to env::var() reads only - Pre-compiled negation regexes with LazyLock - is_doc_file() checks for dot before extracting extension Tests: 836 pass, 0 fail, 0 clippy warnings, fmt clean.

Aji" Date: Wed, 5 Aug 2026 07:15:37 +0700 Subject: [PATCH 10/18] fix(rules): narrow sql-concat, debug-enabled, hardcoded-role patterns (#485, #486, #490) (#492) sql-concat: require SQL keyword inside string literal + post-match filter for comments/docstrings. Regex now needs a quote char before the + to qualify as SQL injection. debug-enabled: remove bare --debug from regex (too many false positives on CLI flags, Dockerfiles, argument parsers). Keep DEBUG = True and debug: true assignments. Add post-match filter for comment lines, argument parser definitions, and env var references. hardcoded-role: add quoted patterns ("admin", 'admin'), strict equality (===), property access (user.role), and superuser to the regex. Now covers JS, TS, Python, Go patterns. Tests: 854 pass (18 new), 0 clippy warnings, fmt clean. Closes #485, closes #486, closes #490.

Aji" Date: Wed, 5 Aug 2026 08:05:09 +0700 Subject: [PATCH 11/18] fix(rules): add post-match filters for eval, weak-hash, ssl-verify (#487) (#493) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add defense-in-depth post-match false-positive filters for the 3 remaining security scanner rules without them: - injection/eval: suppress comments, docstrings, 'evaluate' (not eval), ast.literal_eval (safe) - crypto/weak-hash: suppress comments, docstrings, import/use statements, type annotations - crypto/ssl-verify-disabled: suppress comments, docstrings, env var references, schema definitions, negation patterns This completes epic #487 — all 11 security patterns now have defense-in-depth coverage (narrow regex + post-match filter + doc skip). 18 new tests covering both detection and suppression for each rule.

Aji" Date: Wed, 5 Aug 2026 14:01:25 +0700 Subject: [PATCH 16/18] fix(watch): use global index DB with schema migrations (#498) 'cora watch' was opening a project-local SQLite database at .cora/index.db without running schema migrations, causing a crash ('no such table: projects') on any project that had not been indexed before. Fix: use index::open_global_index() (which runs migrations) instead of manually opening a project-local DB. Also resolve project root via index::resolve_project_root() for consistency with other commands, and expand the file-extension filter to cover all tree-sitter supported languages (php, scala, cs, kt, svelte, jsx, tsx).

Auto-migrates on first run; existing indexes are upgraded transparently. +- **`Backend` enum + `resolve_backend()` in `embed` module.** Clean runtime dispatch with `OnceLock` caching, graceful fallback when a requested backend is not compiled, and `active_dims()` / `active_provider_name()` helpers. +- **`BrainConfig` + `BrainEmbeddingMode` in config schema.** New `brain` section in `.cora.yaml` with `embedding` field. Includes `Display`, `FromStr`, and `serde` impls for CLI and YAML ergonomics. + +### Changed + +- **`embed_code_dispatch()` now checks `ACTIVE_BACKEND` at runtime.** Previously selected via `#[cfg]` at compile time only. Falls back to compile-time default if `resolve_backend()` was never called (lazy resolution). +- **`cora index`, `cora brain`, `cora watch` all resolve embedding backend on startup.** Each command loads `.cora.yaml`, reads `brain.embedding`, and calls `resolve_backend()` before touching the vector index. +- **Embedding doc comments updated.** Module-level docs now describe runtime selection and the three-tier architecture (hashing → pretrained → ONNX future). + ## [0.12.0] ### Fixed diff --git a/Cargo.lock b/Cargo.lock index f4a1fe3..e8aafe7 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -297,7 +297,7 @@ dependencies = [ [[package]] name = "cora-code" -version = "0.12.0" +version = "0.13.0" dependencies = [ "anyhow", "assert_cmd", diff --git a/Cargo.toml b/Cargo.toml index 08810fd..1570d1d 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "cora-code" -version = "0.12.0" +version = "0.13.0" edition = "2024" description = "CLI-first AI code review — BYOK, diff/scan/branch, pre-commit hooks" license = "MIT"
