Three real bugs fixed:
1. FunctionRef always used line=0. Now passes node.lineno from AST.
2. P3_pass results were discarded with bare pass. Now stored in
ProducerConsumerGraph.field_accesses.
3. Field-access detector only saw entry['key']; missed entry.get('key')
which is the dominant pattern in this codebase. Now handles both.
Plus _extract_type_name() helper handles Optional[T], dict[str, T],
list[T], Result[T], Union[T, ...], and T | None (PEP 604) so P1/P2
catch more annotation patterns.
Real numbers (Metadata aggregate):
- producers: 77 -> 117
- consumers: 35 -> 66
- field-access sites: 130 -> 173
- line numbers: all real (line 1281, 1746, etc.)
AUDIT_REPORT.md grew 2009 -> 3140 lines with real evidence.
Total audit output: 5176 lines / 50 files (was 2415 / 49).
All 131 tests still passing.
The previous code did Path(src_dir) / function_ref.file, which
double-prefixed (e.g. src/src/project_manager.py) and silently
returned empty. Fixed: if function_ref.file exists as
CWD-relative, use it directly. Only join if it doesn't exist.
Now 130 real field accesses detected across 35 Metadata consumers
in the 2026-06-22 audit output (was 0 before).
