Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe global sink audit now sanitizes Rust comments and literals, tracks local bindings, analyzes accessor bodies, updates its classified-static floor, and expands self-tests for false positives and valid global references.

Defer local binding activation until the statement-level semicolon.
referenced_idents activates pending for every ;. In let BARE_TABLE = [0; BARE_TABLE];, the array-repeat semicolon therefore marks BARE_TABLE as local before the RHS identifier is scanned. The audit can omit the real global reference.
Track () and [] nesting, and activate pending bindings only when nesting[-1] == 0. Add this array-repeat case to self_test().

Fixes #10953.
The global-sink audit now blanks Rust comments and string/char literals before finding helper bodies, static declarations, and uppercase references. It tracks simple block-local
constandletbindings, activating them after the initializer and keeping accessor bodies in separate scopes. The obsoleteAPIallowlist entry is removed.The self-test places a bare static alongside comment, literal, and local-shadow lookalikes, and verifies the bare static remains a violation. On current
main, the full gate reports 0 hazards, 5 allowlisted, and 115 classified statics (down from 120 comment-inflated names).Verification:
python3 scripts/global_sink_isolation.py --self-test,python3 scripts/global_sink_isolation.py,python3 -m py_compile scripts/global_sink_isolation.py, andgit diff --check.PR #10947 also edits this scanner and adds
scripts/global_sink_asserted_baseline.txt. If it lands first, this branch should be rebased and that baseline reviewed against the masked identifier population.Summary by CodeRabbit
