**Status:** PASS
**Produced By:** skill-creator-max (Phase 6)
**Date:** 2026-04-20
**Skill:** RAM S3 -- Multi-Method Orchestrator

## Input Files Consumed

- Phase 4 SKILL.md -- `phase-4-ram-skills/multi-method-orchestrator/SKILL.md`
- Phase 5 LIBRARY_ARCHITECTURE.md (placement authority)
- Phase 5 CROSS_CUTTING_ARTIFACTS.md (Surprise Register + RAM Search Ledger schemas)

## Output Files Written

Skill directory: `phase-6-skills/ram/multi-method-orchestrator/`
- `SKILL.md` (copied from Phase 4)
- `references/TRIANGULATION_PROTOCOL.md` (Private RAM; ~475 words)
- `references/SINGLE_METHOD_EXCEPTION_PROTOCOL.md` (Private RAM; ~490 words; CLOSED trigger list)
- `templates/CLAIM_TRIANGULATION_RECORD.md` (Private RAM; schema + invariants)
- `HANDOFF.md` (this file)

Public RAM directory: `phase-6-skills/ram/_public/`
- `references/orchestration/DISCIPLINE_SELECTION_MATRIX.md` (Public RAM; shared with S8; SETS not singletons)
- `references/shared-ram/SURPRISE_REGISTER_WRITE_CONTRACT.md` (Public RAM; shared write contract)
- `references/shared-ram/SEARCH_LEDGER_WRITE_CONTRACT.md` (Public RAM; shared write contract)
- `templates/SURPRISE_REGISTER_ENTRY.md` (Public RAM; shared entry format)

Word counts per private reference are within 200-500 budget. Double hyphens used throughout; zero em dashes. Zero-overlap maintained -- all Evaluator surfaces untouched.

## Summary

Seven reference and template files authored per Phase 4 SKILL.md and placed per Phase 5 LIBRARY_ARCHITECTURE.md. Private skill-local files (TRIANGULATION_PROTOCOL, SINGLE_METHOD_EXCEPTION_PROTOCOL, CLAIM_TRIANGULATION_RECORD) live under the skill directory. Public shared files (DISCIPLINE_SELECTION_MATRIX, SURPRISE_REGISTER_WRITE_CONTRACT, SEARCH_LEDGER_WRITE_CONTRACT, SURPRISE_REGISTER_ENTRY) live under `_public/` with the subpaths specified in the placement table. All load-bearing invariants from Phase 4 (matrix-returns-sets, CLOSED trigger list, Research Auditor non-removable, CLAIM_TYPE_REVISION halts and returns to S5, no procedural tiebreakers) are carried forward in the reference bodies.

## Key Decisions (3 load-bearing)

1. **DISCIPLINE_SELECTION_MATRIX written as SET-returning ONLY.** All 5 baseline sets have size 4 with Research Auditor included. Fitness and debiasing overlays are additive-only; subtractive operations are prohibited at the matrix level. Size-1 lookup result is declared an authoring defect at the top of the file.
2. **SINGLE_METHOD_EXCEPTION_PROTOCOL carries a CLOSED 4-trigger list (T1-T4).** REJECTED rationales are explicitly enumerated: efficiency, best-fit, obvious-method, and five social-pressure framings. Ledger enforcement refuses writes with missing fields.
3. **Research Auditor non-removable from baseline sets.** Stated in DISCIPLINE_SELECTION_MATRIX and in CLAIM_TRIANGULATION_RECORD invariants (`research_auditor_present` MUST be true). Capacity-ceiling deferrals pull from non-Auditor disciplines only.

## Confidence

HIGH. Matrix-returns-sets constraint is structurally encoded (all baseline sets authored as size 4; size-1 declared a defect). Single-method exception list is closed and names the failure-mode rationales. CLAIM_TYPE_REVISION routes to charter-amendment-request entry kind with halt-and-return-to-S5 mandated in both the Write Contract and Phase 3 SKILL.md language.

## Smoke Test Verdict

PASS. Read directives from SKILL.md File Registry resolved against produced files:
- `references/DISCIPLINE_SELECTION_MATRIX.md` -> `_public/references/orchestration/` (Public RAM, per placement)
- `references/TRIANGULATION_PROTOCOL.md` -> skill-local (Private RAM)
- `references/SURPRISE_REGISTER_WRITE_CONTRACT.md` -> `_public/references/shared-ram/` (Public RAM)
- `references/SEARCH_LEDGER_WRITE_CONTRACT.md` -> `_public/references/shared-ram/` (Public RAM)
- `references/SINGLE_METHOD_EXCEPTION_PROTOCOL.md` -> skill-local (Private RAM)
- `templates/CLAIM_TRIANGULATION_RECORD.md` -> skill-local (Private RAM)
- `templates/SURPRISE_REGISTER_ENTRY.md` -> `_public/templates/` (Public RAM)

Seven referenced files, seven files written, zero phantom references. Word budget per file within 200-500. Plugin Packager (Phase 8) will resolve public vs private path injection at packaging time.

## Gaps

None blocking. Two design notes for downstream:
- The SKILL.md authored paths use bare `references/X.md` form; Plugin Packager must inject or path-rewrite public files into the skill's runtime reference surface so Read directives resolve without `../_public/` traversal.
- TRIANGULATION_PROTOCOL material-difference thresholds (section 3) are quantified heuristically (effect-size > 2x, Brier delta > 0.1); Phase 9 calibration may tighten these.

## Next Phase

- Phase 7 Coordinator orchestration (integrate S3 into the RAM pipeline with S5 -> S1/S7 -> S2 -> S3 -> S8 -> S6 -> S4)
- Phase 8 Plugin Packaging (resolve public/private path injection)
- Phase 9 Evaluation (calibrate material-difference thresholds; monitor single-method-collapse rate)

## Reopen Triggers

- Any Phase 7 test produces a Triangulation Record with discipline subset size = 1 and no SINGLE_METHOD_EXCEPTION ledger stamp -> reopen SKILL.md Phase 2 step 5 protocol.
- Phase 9 multi-method triangulation rate < 50% on stacked-intent test set -> reopen DISCIPLINE_SELECTION_MATRIX.
- Surprise Register entries written by S3 violating Claim-Typing Engine ownership contract -> reopen SURPRISE_REGISTER_WRITE_CONTRACT.
- Phase 6 cross-skill smoke test shows any public file referenced by S3 absent from `_public/` placement -> reopen Phase 5 LIBRARY_ARCHITECTURE for S3 rows.
