From 6ec3a2e68b014e40f7f717e589d8d8765b1dd6c8 Mon Sep 17 00:00:00 2001 From: "Anaz S. Aji" Date: Fri, 11 Sep 2026 12:13:39 +0700 Subject: [PATCH 01/22] fix(ci): make cla-check work for fork PRs (#553) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CLA gate relied on a manually POSTed commit status. Fork PRs run workflows with a read-only GITHUB_TOKEN regardless of declared permissions, so the status step always 403s on forks — every external fork PR was permanently red even with a signed CLA. The bot comment step also 403s on forks. - Drop the commit-status step and statuses:write; the gate now rides on this job's own Actions check run (fork-safe by construction). - Comment step becomes same-repo-only + continue-on-error (courtesy, never a gate). Unsigned path emits a ::error annotation with the portal link instead. - github-script upgraded to v9. Validated end-to-end on codecoradev/uteke (PR #1224 + E2E probe).

Pin 0.23.45 (same remediation as gaira 2026-10-03); rustls-webpki rides along to 0.103.15. Closes #560. - 'use std::f32;' in the vector tests module resolves f32::EPSILON to the deprecated module-path constant: clippy -D warnings is red on rustc 1.99, now including CI's stable toolchain. Removing the import restores the associated-constant resolution. Closes #557. Lockfile + one test-only line; no runtime code paths touched.

Aji" Date: Wed, 7 Oct 2026 14:58:47 +0700 Subject: [PATCH 06/22] fix(index): key files by project, exact-match callers, auto-prune, honor skip patterns (#565) - schema v8: files keyed by (project_id, path) so projects sharing a relative path no longer overwrite each other's fingerprint (perpetual reindex). - graph: find_callers/callees/trace use exact match instead of LIKE '%x%' (run no longer matches rerun; _ and % are not wildcards). - index runs auto-prune stale files; pruning also clears edges. - serve and watch use index_project_with_skip with resolved config patterns.

Aji" Date: Wed, 7 Oct 2026 15:38:03 +0700 Subject: [PATCH 07/22] security(upgrade): harden self-update and installer verification (#572) Exact-match checksum lookup, random 0700 temp dir, extract only the regular-file binary entry (reject symlink/hardlink), request timeouts and size caps, no-redirect version probe with tag validation, and require an explicit ack to skip checksums. install.sh now fails closed on missing checksums, falls back to shasum, and rejects link entries.

Aji" Date: Wed, 7 Oct 2026 15:39:11 +0700 Subject: [PATCH 09/22] refactor(index): single seam for resolving project root and opening the index (#574) Evolve IndexBridge into the one module that resolves the project root (via resolve_project_root), opens the index with shared PRAGMAs, and ensures the project id. Tolerant mode for review, strict mode for CLI/MCP. Index scanners and brain context take the bridge, so a review run from a subdirectory resolves the same project_id as indexing from the root.

Aji" Date: Wed, 7 Oct 2026 15:53:17 +0700 Subject: [PATCH 10/22] fix(affected): unify affected-tests and dead-code queries between CLI and MCP (#575) Add src/index/queries.rs as the single implementation. Fixes the CLI stem bug (extension used as stem), adds LIKE ESCAPE, batches queries, and makes MCP dead-code honor analysis.entry_point_patterns from project config.

Aji" Date: Thu, 8 Oct 2026 08:56:31 +0700 Subject: [PATCH 16/22] fix(watch): reindex only files that changed; --filter restricts what is indexed (#584) detect_changes returned every source file on every tick and the whole project was reindexed after a trigger, so --filter only gated whether a cycle fired. The watch loop now keeps an (mtime, size) snapshot, diffs it each tick (new/modified/deleted), applies the ext/git-only/--filter/skip filters, and reindexes only the changed files via a new include predicate (IndexSession::index_matching). Deletions are pruned by the same run; idle ticks do no indexing work. Fixes both cora watch and index --watch.

Aji" Date: Thu, 8 Oct 2026 10:15:25 +0700 Subject: [PATCH 17/22] refactor(store): single review_store module owns review-history SQL (#585) Move all SQL for reviews/findings/finding_events into engine::review_store (replaces engine::db_writer). cora findings, debt tracker and review/scan persistence call it and hold no SQL. Store takes a &Connection so it is testable with in-memory SQLite; best-effort persistence policy is explicit in persist_review_best_effort.

Aji" Date: Thu, 8 Oct 2026 10:45:02 +0700 Subject: [PATCH 18/22] fix(findings): make --severity filter and list colouring case-insensitive (#588) Severities are stored lowercase, but the filter upper-cased its argument (never matching) and the renderer matched uppercase literals (no colour). Lowercase the filter argument, colour via a pure case-insensitive helper, and validate --severity (info|minor|major|critical, any case) in clap.
