## Files Written

### SKILL.md (1 file)
- `phase-6-skills/ram/claim-typing-engine/SKILL.md`
  - Copied from Phase 4 SKILL.md with Phase 5 placement edits (see "SKILL.md Edits" below).

### Private RAM references (3 files; skill-local, live under `claim-typing-engine/references/`)
- `references/STACKED_INTENT_DECOMPOSITION.md` -- verb-account procedure, decomposition decision tree, worked examples, ambiguous-verb disambiguation.
- `references/MONOCULTURE_TRIGGERS.md` -- 4-dimension trigger schema (D1 domain-sensitivity / D2 geographic-locus / D3 practitioner-domain / D4 claim-type context-dependency), emission rules, worked examples, downstream contract with S1.
- `references/ANTI_EXAMPLES.md` -- 6 worked mis-typing anti-patterns (majority-type default, type-blending, monoculture-flag silencing, register-as-tiebreaker, anti-sycophancy, skipped-tokenization) with wrong/defect/right structure.

### Public-RAM files (5 files; OWNED by S5; under `ram/_public/`)
- `_public/references/typology/CLAIM_TYPE_TYPOLOGY.md` -- canonical 5-type taxonomy (descriptive/causal/predictive/normative/interpretive) with anchor questions, load-bearing source properties, paradigm citations per Phase 3 S02 findings.
- `_public/references/fitness/FITNESS_REQUIREMENTS_BY_CLAIM_TYPE.md` -- parameterized single-schema per-type (load-bearing properties, disqualifiers, weight overrides, fragility flags) honoring R2.4.
- `_public/references/shared-ram/SURPRISE_REGISTER_OWNERSHIP_PROTOCOL.md` -- S5-owner invariants, write contract for {S3, S7, S8}, inquiry-expansion rule, lifecycle, degraded-mode, re-entry persistence.
- `_public/templates/CLAIM_DECOMPOSITION_ARTIFACT.md` -- YAML scaffold for the primary emit; versioned, self-check-gated, downstream-consumer mapped.
- `_public/templates/SURPRISE_REGISTER_INSTANCE.md` -- empty register scaffold (manifest.json + empty register.jsonl) with instantiation checklist; mirrors Phase 5 cross-cutting schema.

**Total files authored: 9.** (1 SKILL.md + 3 private references + 5 public-owned).

## SKILL.md Edits Made

- **File Registry section:** expanded to separate "Public-RAM files (owned by this skill)" with placement under `_public/references/<sub>/` + `_public/templates/` and "Private-RAM files (skill-local)" with `references/` placement. Phase 4 SKILL.md listed all files under flat `references/` and `templates/`; edited to reflect Phase 5 library architecture.
- **Operating Logic Read directives:** 6 path-qualified edits -- CLAIM_TYPE_TYPOLOGY (2x in Phase 1 & Phase 2), FITNESS_REQUIREMENTS (Phase 4), SURPRISE_REGISTER_OWNERSHIP_PROTOCOL (Phase 6), SURPRISE_REGISTER_INSTANCE (Phase 6), CLAIM_DECOMPOSITION_ARTIFACT (Phase 7). Private references (STACKED_INTENT_DECOMPOSITION, MONOCULTURE_TRIGGERS, ANTI_EXAMPLES) retained as `references/X.md`.
- **Anti-Examples section:** added a pointer to `references/ANTI_EXAMPLES.md` at run start; retained inline 4-example summary for at-a-glance doctrine.
- **NEVER rule #1:** re-pathed memory-drift-file reference.

No other content changes. All NEVER / ALWAYS rules preserved verbatim. All Phase 0 non-negotiables enforcement language preserved.

## Smoke-Test Verdict

Every `Read` directive in SKILL.md resolved to a file that now exists. Verified programmatically:

```
OK  _public/references/typology/CLAIM_TYPE_TYPOLOGY.md
OK  references/STACKED_INTENT_DECOMPOSITION.md
OK  _public/references/fitness/FITNESS_REQUIREMENTS_BY_CLAIM_TYPE.md
OK  references/MONOCULTURE_TRIGGERS.md
OK  _public/references/shared-ram/SURPRISE_REGISTER_OWNERSHIP_PROTOCOL.md
OK  references/ANTI_EXAMPLES.md
OK  _public/templates/CLAIM_DECOMPOSITION_ARTIFACT.md
OK  _public/templates/SURPRISE_REGISTER_INSTANCE.md
```

**Verdict: PASS -- 8/8 Read directives resolve.**

## Zero-Overlap Audit

- No content crosses the RAM/Evaluator silo. All references authored live under `ram/` path tree.
- Surprise Register schema matches Phase 5 CROSS_CUTTING_ARTIFACTS.md Section 1 exactly -- owner (S5), writers ({S3, S7, S8}), renderer (S4), reader-gate (S6), prohibited entry kinds ({tiebreaker-vote, confidence-delta}), path root (state/ram/surprise-register/).
- Surprise Register record-kinds disjoint from Evaluator Search Ledger's record-kinds (Phase 5 Section 4).
- No file shared between RAM and Evaluator (no duplication into `evaluator/` tree).
- No em dashes used; double hyphens throughout per discipline note.

## Open Dependencies and Flags

- **Coordination with sibling skills under `_public/`:** `SURPRISE_REGISTER_ENTRY.md` (authored by S3 agent) and `SEARCH_LEDGER_WRITE_CONTRACT.md` / `SURPRISE_REGISTER_WRITE_CONTRACT.md` (under shared-ram) exist and are consistent with this skill's write contract. Pre-existing S1_LEDGER_WRITE_MANIFEST.md at `_public/` root looks like a stray; not owned by this skill, flagged for orchestration-layer cleanup.
- **Search Ledger writethrough contract:** Phase 5 designates S4 as owner of the Search Ledger; S5 writes through via entry_type = "decomposition". CLAIM_DECOMPOSITION_ARTIFACT.md template carries the writethrough block. Implementation of the atomic-append mechanism belongs to the S4 skill + orchestration layer.
- **Phase 6 acceptance threshold carried:** typing accuracy >= 85% on bounded-test stacked-intent questions (per Phase 2A Section 13.2). Test harness not part of this HANDOFF; downstream validation.
- **Fragile-rubric-flag propagation:** depends on S4 Output Layer honoring the flags at render. Verified in S4 SKILL.md (cross-read during authoring).
- **UNTYPABLE escalation:** routes to Evaluator reopen authority; depends on E7 reopen-event record shape (Phase 5 Evaluator Search Ledger 4.3.5). No blocker; contract is one-way.

No HALT conditions. Ready for Phase 6 downstream build (S7 Fitness Adjudicator next per build order).
