Code Audit #6 of 17

Apply the code quality criteria from CONTRIBUTING.md "What Good Code Looks Like":

Files to audit:

crates/compiler/src/lint.rs
crates/compiler/src/resource_lint.rs

Checklist:

Structure: First 50 lines tell you what file does, logical function ordering
Naming: Functions say what they do, variables reveal intent
No Surprises: All public functions used, no commented-out code, no stale TODOs
Single Responsibility: Each function does one thing, consistent error handling
Tests: Complex logic has tests, edge cases covered

Audit Complete

Files Reviewed

crates/compiler/src/lint.rs (~875 lines) - Pattern-based linting engine
crates/compiler/src/resource_lint.rs (~1862 lines) - Resource leak detection

Findings

lint.rs:

Well-structured pattern-based linting inspired by clippy
Supports wildcards (X single, ... multi) for flexible pattern matching
Deep nesting detection with configurable threshold
Clear severity levels (Error, Warning, Hint)
No TODOs, FIXMEs, or commented-out code

resource_lint.rs:

Sophisticated data flow analysis for WeaveHandle and Channel resources
Stack simulation through all operations (dup, swap, rot, pick, roll, etc.)
Branch consistency checking ensures if/else handle resources identically
Escape analysis properly identifies resources returned to caller
Cross-word analysis via ProgramResourceAnalyzer
No TODOs, FIXMEs, or commented-out code

Tests

25 linting tests pass

Assessment

Both modules demonstrate excellent code quality with thorough documentation and comprehensive test coverage. The resource linting is particularly sophisticated, handling complex control flow and stack manipulation scenarios correctly.
