From 068f5959c2408ad88eb2459643428be968aa03a7 Mon Sep 17 00:00:00 2001 From: CodeWhale Bot Date: Sun, 13 Sep 2026 02:21:14 -0700 Subject: [PATCH 1/4] Improve GitHub App reviews with pinned source context and concrete findings Give the shared CLI/tool PR reviewer numbered surrounding source from raw regular blobs at the exact PR head. Preserve the complete diff, inline anchors, existing input/pass budgets, and provider-call count. Collect source off the async runtime and identify omitted context. Require concrete triggers, evidence, impact and fixes; reject speculative compiler claims and generic test nits in the review rubric. Refs #6135 (SHA-6514). Validation: npm test && npm run check:web passed: 66 package tests, 9 SDK tests, 446 web tests, 0 failures; web lint/types/facts/production build passed. Focused cargo test -p codewhale-tui --lib --locked tools::review: 60 passed, 0 failed, 0 ignored. Standalone hunk-parser tests: 15 passed, 0 failed. The Rust repeated-match negative control compiled with -D warnings and passed all four variants. No provider call, GitHub review publication or deployment.

That test has never executed on Windows since it was written. Gating it to unix accepts that permanently, and it gives up coverage on the one platform whose filename rules caused the failure — which is also the platform where a path bug is most likely to differ from the others. The fixture can just be spelled portably. `[l]iteral-other.rs` uses only NTFS-legal characters (the reserved set is `< > : " / \ | ? *`; brackets are fine) and proves exactly the same property: - read literally, the pathspec names that file; - read as a glob, `[l]` matches the single character `l` and the pattern resolves to `literal-other.rs` — the "wrong glob match" decoy the test already creates two lines down. So an implementation that globs still reads the decoy and still trips `assert!(!context.to_string().contains("wrong glob match"))`. The `nested/` relative-path decoy is unaffected. Verified empirically rather than from the spec: with both files present, the shell glob `[l]iteral-other.rs` selects `literal-other.rs`. The diagnosis in 55fffb3db is what made this fix obvious; only the remedy changes.
