lakehouse/auditor 4 blocking issues: todo!() macro call in tests/real-world/scrum_master_pipeline.ts
Phase A — data model (vectord/src/pathway_memory.rs):
+ SemanticFlag enum (9 variants: UnitMismatch, TypeConfusion,
NullableConfusion, OffByOne, StaleReference, PseudoImpl, DeadCode,
WarningNoise, BoundaryViolation) as #[serde(tag = "kind")]
+ TypeHint { source, symbol, type_repr }
+ BugFingerprint { flag, pattern_key, example, occurrences }
+ PathwayTrace gains semantic_flags, type_hints_used, bug_fingerprints
all #[serde(default)] for back-compat deserialization of pre-ADR-021
traces on disk
+ build_pathway_vec now tokenizes flag:{variant} + bug:{flag}:{key}
so traces with different bug histories cluster separately in the
similarity gate (proven by pathway_vec_differs_when_bug_fingerprint_added
test)
Phase B — producer (scrum_master_pipeline.ts):
+ Prompt addendum: each finding must carry `**Flag: <CATEGORY>**` tag
alongside the existing Confidence: NN% tag. 9 category choices plus
`None` for improvements that aren't bug-shaped.
+ Parser extracts tagged flags from reviewer markdown; falls back to
bare-word match if reviewer omits the label. Deduplicated per trace.
+ PathwayTracePayload gains semantic_flags / type_hints_used /
bug_fingerprints fields. Wire format matches Rust serde tagged enum
so TS and Rust interop directly.
Phase C — pre-review enrichment:
+ new `/vectors/pathway/bug_fingerprints` endpoint aggregates
occurrences by (flag, pattern_key) across traces sharing a narrow
fingerprint, sorts by frequency, returns top-K.
+ scrum calls it before the ladder and prepends a PATHWAY MEMORY
preamble to the reviewer prompt ("these patterns appeared N times
on this file area before — check for recurrences"). Empty on
fresh install; grows as the matrix index learns.
Tests: 27 pathway_memory tests green (was 18). New tests:
- pathway_trace_deserializes_without_new_fields_backcompat
- semantic_flag_serializes_as_tagged_enum
- bug_fingerprint_roundtrips_through_serde
- pathway_vec_differs_when_bug_fingerprint_added
- semantic_flag_discriminates_by_variant
- bug_fingerprints_aggregate_by_pattern_key (sums occurrences, sorts desc)
- bug_fingerprints_empty_for_unseen_fingerprint
- bug_fingerprints_respects_limit
- insert_preserves_semantic_fields (roundtrip via persist + reload)
Workspace warnings unchanged at 11.
What's still queued (not this commit):
- type_hints_used population from catalogd column types + Arrow schema
- bug_fingerprint extraction from reviewer output (Phase D — for now
semantic_flags populate but the fingerprint key requires parsing
code-shape from the finding; next iteration's work)
- auditor → pathway audit_consensus update wire (explicit-fail gate)
Why this commit matters: the mechanical applier's gates are syntactic
(warning count, patch size, rationale-token alignment). The
queryd/delta.rs base_rows bug (86901f8) was found by human reading —
unit mismatch between row counts and file counts. At 100 bugs this
deep, humans can't catch them all; the matrix index has to learn the
shapes. This commit gives it the fields to learn into and the surface
to read from.
