# HANDOFF -- Multi-Corpus Retrieval Router (RAM S1, Phase 6 build)

**Phase:** 6 -- skill-creator-max
**Component:** Multi-Corpus Retrieval Router (RAM S1)
**Date:** 2026-04-20
**Status:** ASSEMBLED. Smoke-test PASS (self-verified). Ready for Phase 7 orchestration.

---

## 1. What This Build Produced

- `SKILL.md` -- operating logic derived verbatim in shape from the Phase 4 instruction-engineered source. No scope inflation; no new authority added.
- `references/CARE_GATE_PROTOCOL.md` -- operational G1-G4 decision tree; Carroll 2020 as binding doctrine.
- `references/MONOCULTURE_TRIGGER_PROTOCOL.md` -- T1-T4 trigger table with explicit tests and Decision Points M1/M2/M3.
- `references/CORPUS_SURFACE_CATALOG.md` -- four-surface catalog with engagement rules and dispatch-set mapping.
- `references/TRANSLATION_FIDELITY_RULES.md` -- OpenAlex-as-INPUT rule with concrete triple-check; three fidelity levels; Decision Point F1.
- `references/EXTERNAL_API_CLIENTS.md` -- per-surface dispatch notes; parallelism budgets; Q1 anti-site-operator rule.
- `templates/RETRIEVAL_QUERY_RECORD.md` -- four ledger record kinds with S1 extensions and reconciliation rule.

## 2. Read-Directive Resolution (smoke-test)

| SKILL.md directive | Resolves to | Verdict |
|---|---|---|
| `references/CARE_GATE_PROTOCOL.md` | file exists, 200-500 words, G1-G4 operational | PASS |
| `references/CORPUS_SURFACE_CATALOG.md` | file exists, four surfaces + dispatch mapping | PASS |
| `references/MONOCULTURE_TRIGGER_PROTOCOL.md` | file exists, T1-T4 testable + M1/M2/M3 logic | PASS |
| `references/TRANSLATION_FIDELITY_RULES.md` | file exists, OpenAlex-as-INPUT concrete check + F1 | PASS |
| `references/EXTERNAL_API_CLIENTS.md` | file exists, per-surface dispatch + Q1 rule | PASS |
| `templates/RETRIEVAL_QUERY_RECORD.md` | file exists, four record kinds + reconciliation | PASS |

## 3. Discipline Audit

- **CARE protocol is concrete + operational.** G1-G4 each carry PASS/FAIL/UNKNOWN tests; corpus-level AND record-level checks; operator-override rules are explicit.
- **Monoculture trigger table is testable.** T1 has a closed-set domain test. T2 has an Anglophone-core exclusion. T3 has a closed verb/role set. T4 is a direct field read. Decision Points M1/M2/M3 are explicit.
- **OpenAlex language-field-as-INPUT-only rule is a concrete check.** Step-numbered triple-check (script + venue + abstract sampling); `openalex_language_mismatch` recorded per record; writing `language_detected = lang_input` is a named defect class.
- **Word counts:** each reference in the 400-500 word range; each within the 200-500 envelope.
- **Double hyphens:** verified; no em dashes in output.
- **Zero-overlap:** S1 references do not duplicate any file declared in Phase 5 placement map for other skills. S1 does NOT author any file placed in `ram/references/shared-ram/` or `ram/references/typology/` (those are S5 / S3 design-time artifacts).

## 4. Public-RAM Contribution

`_public/S1_LEDGER_WRITE_MANIFEST.md` -- S1-side writer obligations against the `ram/references/shared-ram/SEARCH_LEDGER_WRITE_CONTRACT.md` doctrine (that canonical multi-writer file is owned by S3's build per LIBRARY_ARCHITECTURE row 3.5; S1 contributes only its writer manifest to avoid authoring outside scope).

## 5. Cross-Cutting Artifact Touch

- **RAM Search Ledger:** S1 is a WRITER. Schema owned by S4. S1 writes four record kinds per `templates/RETRIEVAL_QUERY_RECORD.md`. Reconciliation rule is `count(every-query) - count(every-accepted) - count(every-rejected) == count(every-skipped[dispatch-failure])`.
- **Surprise Register:** S1 does NOT write. S1 is not listed in the writer set {S3, S5, S7, S8}.
- **Frame Registry:** Evaluator silo; S1 has zero access.
- **Evaluator Search Ledger:** Evaluator silo; S1 has zero access.

## 6. Flags / Open Items for Phase 7 + Phase 9

- **Open parameter:** per-discipline thresholds for M1 / M2 heuristics (SKILL Section 2.3) await Phase 9 smoke-test calibration.
- **Open parameter:** translation-fidelity threshold for `fidelity_review_required` awaits Phase 9 calibration on Bergamaschi-and-Pinheiro (2021) plus comparator non-English sources.
- **Architectural limit** (Indigenous-community-controlled primary corpora unreachable) MUST be rendered by S4; Phase 7 coordinator must wire S4 to consume and render `architectural_limit_disclosure` entries.
- **Zero-overlap note:** S1 does not own the canonical `SEARCH_LEDGER_WRITE_CONTRACT.md`. If a later skill-builder run (S3) has not produced it by Phase 7, that is a gap to raise at coordinator assembly -- not an S1 repair.

## 7. Failure Modes Retained From Phase 4

Phase 4 Section 5 failure audit preserved verbatim in SKILL.md Rules (1-10) and in the references' anti-pattern sections. No softening; no aggregation.

## 8. Next Consumer

S2 Source Integrity Screen consumes accepted records with the full S1 tag set. S2 adds `integrity_verdict_ref` and `admiralty_input`; S1 does not touch those fields.

**End of HANDOFF.**
