Hypothesis under test by the owner: coherent extractions turn to mush after merging because the auditor minted too many bridging edges of its own — inference, not identity, and out of the auditor's scope. The graph now connects across sources solely through identified equivalences; relations between propositions come from the extractor alone. - auditSchema drops 'edges' (submit_review = links only); the submit-seam required-field doctrine reworded per tool - AUDITOR_INSTRUCTIONS: the BRIDGING EDGES section dies; deliverable is the identity verdicts only - AuditVerdicts drops edges; ExtractedEdge endpoints are extractor-local ids only; mergeFindings stops consuming verdict edges and its resolve() drops the raw-node-id branch (dead — the extractor never sees graph ids) - extractor untouched: submit_findings keeps propositions + follows/ supports edges, required as before - tests: 17 submit fixtures + 9 typed verdict literals slimmed to links - docs: architecture.md division-of-trust + pipeline diagram updated

/**
|
||
* The extraction pipeline tests (vision §1 construction, 2026-09-02 redesign;
|
||
* relinked 2026-09-27): extractor → auditor → merger, the sole graph writer —
|
||
* the extractor alone sees the source (whole-session markdown), the auditor
|
||
* never does (identity linking through graph tools), the merger is
|
||
* deterministic.
|
||
*
|
||
* transcriptView — the markdown rendering the extractor sees (pure):
|
||
* id-anchored Teacher/Learner blocks + check blocks
|
||
* pipeline — scripted faux engines drive both agents: findings out,
|
||
* audit verdict (with linkTo identity) in, deterministic
|
||
* merge applied; failure paths checkpoint nothing;
|
||
* single-flight per chat
|
||
*
|
||
* The merger itself (identity verdicts, idempotency) is tested in
|
||
* tests/graph.test.ts directly against mergeFindings — here it is the
|
||
* integration: what one full pipeline run does to the ledgers.
|
||
*
|
||
* Ledger: in-memory (the GraphStore port) — this suite never touches
|
||
* data/graph. Chats: real ChatRecords in the real chat store (created and
|
||
* deleted by this suite).
