Dart previously fell through to the regex symbol fallback, which cannot
match type-first signatures (void foo(), Future<int> baz() async), so
classes, methods, and calls were invisible to codebase_symbol,
codebase_flow, and codebase_impact, and files were chunked by line
count instead of declaration boundaries.
- Register @ast-grep/lang-dart as a dynamic grammar (per-grammar
failure isolation keeps missing prebuilds on the regex fallback).
- Add extractFromDart: classes, mixins (trait), enums, extensions,
typedefs, type-first top-level functions, getters/setters, and
constructors including named and factory forms. Scope ranges are
stitched from Dart's sibling function_signature/function_body pairs.
Calls are recovered from argument_part nodes: method calls, bare
calls, constructor invocations, prefixed calls, and cascades.
- Add dart to TOP_LEVEL_KINDS so chunking follows declaration
boundaries; signature and body kinds are both listed so the
overlap-merge fuses each pair into one region.
- Add dart main() to ENTRY_POINT_NAMES for entry-point detection.
- Move Dart to Full Support in the README language matrix.
- 4 new unit test files (22 tests) for graph-symbols, graph-symbol-resolution,
graph-entrypoints, symbol-graph-cache. All 799 tests pass.
- README/AGENTS/CLAUDE/GEMINI: document codebase_impact, codebase_flow,
codebase_symbol, codebase_symbols and updated workflow guidance.
- DEVELOPER.md: new architectural section for symbol-level call graph,
including sharded storage layout and resolution confidence levels.
- CHANGELOG: Unreleased section for the impact-analysis feature.
- Apply CodeRabbit fixes: dedupe in-flight cache loads, set ImpactResult.truncated
when frontier extends beyond depth limit, drop redundant String() around Lang enum.
- Switch reverse-shard hash from SHA1 to SHA256 (Snyk hardening; non-cryptographic use).
