…spine research doc (8th-ferry candidate #2) M-effort technical spine per Amara 8th-ferry landing plan (PR #274). Defines the 4-layer substrate (canonicalisation + representation + retrieval + scoring-sketch) that the provenance-aware bullshit detector (candidate #3) and operational EVIDENCE-AND-AGREEMENT (candidate #4) build on. Four-layer structure: **Layer 1 — Canonicalisation N(x)** with 4 required properties (idempotent / deterministic / meaning-preserving / version-pinned). Input-type archetypes (natural-language / structured / code-diffs) named as downstream design choices, not committed. **Layer 2 — Representation φ(c)** — dense embeddings OR binary semantic hashes (Hinton & Salakhutdinov) OR both. Locality-sensitive hashing (Charikar) as complement for cheap candidate retrieval. Product quantization for corpus-scale compression when warranted. **Layer 3 — ANN retrieval** — HNSW (Malkov-Yashunin 2018) as default with substitutable-interface spine. Retraction- native integration: RetrievalIndex IS a Zeta-module materialised view over event stream (insert/remove); `remove` is a negative-weight event not a tombstone. Same pattern as KSK-as-Zeta-module budgets / receipts. Replay-determinism at query-behaviour layer. **Layer 4 — Scoring (sketch only)** — Amara's formulation preserved: score(y|q) = α·sim + β·evidence - γ·carrierOverlap - δ·contradiction Four terms map to: representation+kNN / citations-as-first- class / provenance-graph / retraction-ledger. Full formalisation is candidate #3. Aminata-concern preview (previewed from oracle-scoring-v0 Otto-90 pass): gameable-by-self-attestation (evidence and contradiction must come from independent oracles); parameter- fitting adversary (ADR gate on α/β/γ/δ); false-precision (band output not decimal). PatternLedger schema (retraction-native): - Events: PatternInserted / PatternRetracted / PatternSuperseded / ProvenanceEdgeAdded / ProvenanceEdgeRemoved - Views: CurrentKnownGood / CurrentKnownBad / ContradictingPairs / ProvenanceCone Composition-table shows spine slots into existing substrate without new mechanisms: SD-9 (norm→mechanism); DRIFT pattern 5 (diagnostic→engine); citations-as-first-class (graph→ consumer); alignment-observability (anti-gaming discipline); oracle-scoring v0 (band output pattern); BLAKE3 v0 (parameter_file_sha binding extends to N-version+φ-version); quantum-sensing analogies #2+#4 (correlation and decoherence slot into layers 3 and 4); KSK-as-Zeta-module 7th ferry (same event+view module pattern). Scope limits (6 items): no specific embedding-model commit; no HNSW-exclusive commit; no canonicalisation-specifics commit; no full scoring formalisation (that's #3); no implementation proposal; does not replace citations-as-first- class. 9 dependencies-to-adoption in priority order: Aminata pass at #1; candidate #3 scoring formalisation at #2; candidate #4 operational promotion at #3; parameter choices / library choices / property tests / ADR-gate substrate at downstream positions. Archive-header format self-applied — 15th aurora/research doc in a row. Lands within-standing-authority per Otto-82/90/93 calibration — research-grade substrate synthesis; not implementation; not adoption; not gated. Closes 8th-ferry candidate #2 of 3 remaining (after Otto-96 TECH-RADAR + Otto-97 quantum-sensing). Remaining: - #3 Provenance-aware bullshit-detector (M; composes on top) - #4 EVIDENCE-AND-AGREEMENT future operational (gated on #3) Otto-98 tick primary deliverable.

The schema defines Status ∈ {known-good, known-bad, superseded, unresolved}, but ContradictingPairs is later defined as entries with status=contradicting, which is not representable by that enum. This creates an ambiguous spec for downstream implementation of the ledger/scoring layer, because engineers must guess whether contradiction is a status or an edge type; please make these definitions consistent in this spine doc.

This attribution points to docs/aurora/2026-04-23-amara-physics-analogies-semantic-indexing-cutting-edge-gaps-8th-ferry.md, but that file is not present in this commit’s tree, so the stated provenance chain cannot be audited from the repository. Since this doc is positioned as an extracted spine from that absorb, the reference should resolve to an existing artifact (or the artifact should be added) to keep the research trail verifiable.

The document cites docs/DRIFT-TAXONOMY.md as an existing dependency, but that path does not exist in this commit, which makes the composition claim non-verifiable and sends readers to a dead reference when they try to inspect “pattern 5.” Point this to the actual in-repo taxonomy artifact (or add the promised canonical file) so downstream reviewers can validate the dependency.

Pull request overview
Adds a new research-grade spine document describing a 4-layer framework for semantic canonicalization, representation, ANN retrieval, and provenance-aware scoring, intended as substrate for future “provenance-aware detector” and operational guidance docs.
Changes:
- Introduces a new research doc formalizing the N(x) → φ(c) → kNN → score pipeline and its required properties (determinism, version pinning, replay behavior).
- Sketches a retraction-native “PatternLedger” event model and materialized views to support provenance/contradiction-aware scoring.
- Documents how the spine composes with existing Zeta substrates (SD-9, citations graph, observability, oracle-scoring patterns).

This doc directly attributes content to named contributors/agents (e.g., in the Attribution / Non-fusion sections). Repo operational rules require using role references in docs (names only allowed under memory/persona/** and optionally docs/BACKLOG.md). Please rewrite these references as role-based (e.g., “courier ferry author”, “absorbing agent”, “adversarial reviewer”, “human maintainer”) while preserving provenance via links/PR numbers.

The “BLAKE3 receipt hashing v0” binding is described as parameter_file_sha here, but elsewhere the repo describes the receipt bindings differently (e.g., approval_set_commitment + hash_version). Please align the field names/terminology to the existing receipt-hash documentation so readers don’t implement incompatible “version pin” metadata.

There was a problem hiding this comment.
In the PatternLedger schema, Status is defined as {known-good, known-bad, superseded, unresolved}, but the ContradictingPairs view is described as pairs with “status=contradicting provenance edge”. That’s inconsistent with the schema/events (contradiction seems like it should be an edge_type on provenance edges). Please fix the view definition to match the ledger representation.

Summary
M-effort technical spine per Amara 8th-ferry landing plan (PR #274). Defines the 4-layer substrate for the corrected "rainbow table" framework: canonicalisation + representation + ANN retrieval + scoring-sketch. Substrate for candidates #3 (bullshit detector) and #4 (operational EVIDENCE-AND-AGREEMENT).
Four-layer structure
removeis negative-weight event.score(y|q) = α·sim + β·evidence - γ·carrierOverlap - δ·contradiction. Full formalisation is candidate Round 27 — plugin API + governance split + memory-in-repo #3.PatternLedger (retraction-native)
5 event types + 4 materialised views. No mutable state outside the event stream. Same pattern as KSK-as-Zeta-module.
Aminata-concern preview
Anticipated from oracle-scoring-v0 Otto-90 pass: gameable-by-self-attestation → evidence/contradiction must come from independent oracles; parameter-fitting → ADR gate on α/β/γ/δ; false-precision → band output not decimal.
Composition with 7 existing substrates
SD-9 (norm→mechanism) · DRIFT pattern 5 (diagnostic→engine) · citations-as-first-class (graph→consumer) · alignment-observability (anti-gaming) · oracle-scoring v0 (band pattern) · BLAKE3 v0 (version-pinning extension) · quantum-sensing analogies #2+#4 (correlation+decoherence) · KSK-as-Zeta-module (event+view pattern).
Scope limits (6 items)
No embedding-model commit · no HNSW-exclusive commit · no canonicalisation specifics · no full scoring formalisation (that's #3) · no implementation proposal · does not replace citations-as-first-class.
Authority
Within standing authority per Otto-82/90/93 calibration — research-grade substrate synthesis; not implementation; not adoption; not gated.
