# HANDOFF -- Fitness Adjudicator Skill Assembly (Phase 6)

**Phase:** 6 -- skill-creator-max (assembly)
**Skill:** fitness-adjudicator (RAM component S7 -- secondary binding constraint)
**Date:** 2026-04-20
**Author:** skill-creator-max (Phase 6)
**Inputs consumed:** Phase 4 SKILL.md (fitness-adjudicator); Phase 5 LIBRARY_ARCHITECTURE.md; Phase 5 CROSS_CUTTING_ARTIFACTS.md; Phase 3 S02_session_output.md, S07_session_output.md, TIER-1-KILL-CRITERION-ADJUDICATION.md.

## 1. Assembly summary

Built the complete Fitness Adjudicator skill directory with 10 authored files:

- `SKILL.md` -- copied verbatim from Phase 4 (authoritative operating logic).
- `references/SHARED_SCHEMA.md` -- concrete D1-D5 dimensions with per-dimension scoring rubric.
- `references/CLAIM_TYPE_PROFILES.md` -- concrete weight vectors, load-bearing dimension sets, fragile-rubric markers for all five claim types.
- `references/DISCIPLINE_PRIORS.md` -- 11-discipline modifier table with [0.5, 1.5] bounds and renormalization rule.
- `references/ADMIRALTY_AS_INPUT.md` -- Baker 1968 anti-collapse doctrine + anti-substitution rule.
- `references/LINEAGE_INDEPENDENCE.md` -- R7.3 metric thresholds as D3 inputs.
- `references/DISQUALIFIERS.md` -- five claim-type-specific veto hooks + three cross-type veto conditions.
- `references/ANTI_DEVIATION.md` -- six concrete self-checks with testable procedures and repair actions.
- `templates/FITNESS_OUTPUT.md` -- per-(source, claim) fitness record schema with validation rules.
- `templates/LEDGER_WRITE.md` -- skill-local mirror of the public canonical template (S7 writes only `every-accepted`, `every-rejected`, `every-skipped`, occasional `every-query`).
- `templates/SURPRISE_WRITE.md` -- skill-local mirror of the public canonical template (S7 anomaly write conditions specified).

Public RAM canonical copies of LEDGER_WRITE.md and SURPRISE_WRITE.md placed at `/build/phase-6-skills/ram/_public/templates/` per Phase 5 LIBRARY_ARCHITECTURE.md rows 113-114.

## 2. Architectural decisions made at assembly

1. **Dual-location templates.** LEDGER_WRITE.md and SURPRISE_WRITE.md are canonical-public AND skill-local-mirrored. SKILL.md Read directives reference `templates/<name>.md` (relative); the skill-local mirror satisfies that Read. The public copy at `_public/templates/` is source-of-truth per Phase 5. Both files carry the canonical-location header.

2. **Concrete D4 score ladder.** Phase 4 SKILL.md specified Baker 1968 anti-collapse as mandatory but did not fix a scoring ladder for Admiralty inputs. Assembled a 0-5 ladder tied to A1 / A2 / B3 / C2 / D-F bands in ADMIRALTY_AS_INPUT.md. Grounded in SANS 2020 + Capet & Revault d'Allonnes 2019.

3. **Explicit D3 threshold set.** LINEAGE_INDEPENDENCE.md codifies thresholds (BC 0.10 / 0.25 / 0.40; founder concentration 0.60; modularity Q 0.70). Phase 3 S07 marked these as PARTIAL (calibration-pending). Defaults documented; recalibration trigger preserved in SKILL.md.

4. **Six-check anti-deviation inventory.** ANTI_DEVIATION.md is the discipline surface. Each check has: signature, procedure (testable), repair action. CRAAP-reduction check is grep-testable (count source-type language vs load-bearing-property language in D1 rationale). Fragile-rubric defaulting check is grep-testable per claim type.

5. **Disqualifier hook IDs** from CLAIM_TYPE_PROFILES.md resolve to DISQUALIFIERS.md entries by identifier (AACODS_FLOOR, CAUSAL_IDENTIFICATION_MISSING, PREDICTIVE_CALIBRATION_MISSING, INTERPRETIVE_REFLEXIVITY_MISSING, NORMATIVE_COHERENCE_MISSING). Cross-type disqualifiers (RETRACTED, AI_FABRICATION_CONFIRMED, LINEAGE_COLLAPSED) are always-on.

6. **Fragile-rubric flag preservation.** Predictive and normative claim-type profiles both carry `fragile_rubric: TRUE` and it is the MANDATORY value for those claim types. ANTI_DEVIATION.md Check 5 enforces no defaulting.

## 3. Smoke-test verdict (self-applied before handoff)

**Read-directive resolution:** All 10 `Read:` directives in SKILL.md (Steps 2-7) resolve to existing files inside the skill directory. Verified by direct path check.

**Schema internal consistency:**
- D1-D5 named identically across SHARED_SCHEMA, CLAIM_TYPE_PROFILES, DISCIPLINE_PRIORS, FITNESS_OUTPUT, ANTI_DEVIATION.
- Weight vectors in CLAIM_TYPE_PROFILES sum to 1.0 (each profile checked: descriptive 0.30+0.25+0.15+0.20+0.10=1.00; causal 0.40+0.20+0.10+0.15+0.15=1.00; predictive 0.45+0.15+0.10+0.15+0.15=1.00; interpretive 0.35+0.20+0.15+0.10+0.20=1.00; normative 0.50+0.10+0.10+0.10+0.20=1.00).
- Discipline modifiers all within [0.5, 1.5]; indigenous-knowledge D4 hits floor 0.5 (documented).

**Anti-tier self-check concreteness:** ANTI_DEVIATION.md Check 1 specifies grep procedure. Check 3 (CRAAP-reduction) specifies removal-and-substitutability test. Check 5 (fragile-rubric defaulting) specifies per-claim-type grep terms. All six checks are testable, not aspirational.

**Zero-overlap with Evaluator:** Confirmed. Fitness Adjudicator writes ONLY to `state/ram/` paths (ram-search-ledger, surprise-register). No reference to Evaluator artifacts. Templates explicitly restate zero-authority boundaries.

**Zero-overlap with other RAM skills:** Fitness Adjudicator does NOT re-run S2 integrity (D2 reads S2 output, does not recompute). Does NOT retrieve (S1 domain). Does NOT type claims (S5 domain). Does NOT triangulate (S3 domain). Lineage computation is UPSTREAM (R7.3 metrics consumed, not produced here).

**Verdict:** PASS.

## 4. Open flags

1. **Threshold calibration -- D3.** Phase 3 S07 flagged BC / modularity / founder-concentration thresholds as PARTIAL. Phase 9 evaluation must per-discipline calibrate. Reopen trigger preserved in SKILL.md.
2. **Threshold calibration -- discipline priors.** [0.5, 1.5] modifier range is defensible but not empirically calibrated across the inherited 11 disciplines. Phase 9 evaluation must measure differentiation; SKILL.md reopen trigger preserved.
3. **Fragile-rubric keystone metric.** "Keystone source = > 30% of total claim-support weight" is asserted in CLAIM_TYPE_PROFILES.md and ANTI_DEVIATION.md Check 6. Phase 7 orchestration test should verify the Multi-Method Orchestrator computes this consistently.
4. **Public template sync.** LEDGER_WRITE.md and SURPRISE_WRITE.md exist in BOTH `_public/templates/` and `fitness-adjudicator/templates/`. Any future edit must update both locations; treating `_public/` as source-of-truth. Phase 6 packaging should enforce this via a pre-build hash check.
5. **Interface contract with Orchestrator.** Fitness record requires Orchestrator to consult `dimension_scores` not just `fitness_headline`. Phase 7 test should confirm. If Orchestrator routes on headline alone, the interface is weakened and SKILL.md reopen trigger fires.
6. **High-Admiralty disqualification anomaly surface.** DISQUALIFIERS.md writes to Surprise Register whenever Admiralty in {A, B} or {1, 2} pairs with disqualifier. This is the R2.3 evidence surface. Phase 9 evaluation should count these anomalies as a proxy for "Admiralty-not-substituted-for-fitness" operational signal.

## 5. Downstream dependencies

- `multi-corpus-retrieval-router` (S1) MUST populate lineage metrics per R7.3 before S7 scoring.
- `source-integrity-screen` (S2) MUST populate integrity_flags before S7 scoring.
- `claim-typing-engine` (S5) MUST populate claim_type + discipline_tags + instantiate Surprise Register before S7 scoring.
- `epistemic-output-layer` (S4) MUST own Search Ledger and publish write handle before S7 can log.
- `multi-method-orchestrator` (S3) reads fitness_headline + dimension_scores + disqualified + reviewer_flag_required. Contract documented in FITNESS_OUTPUT.md.

## 6. Next worker

Evaluator-side Phase 6 skill-creator for the Evaluator plugin. After all RAM skills assemble, plugin-packaging-max bundles. This skill's HANDOFF is the final build-time artifact from fitness-adjudicator.
