Decision

Adopt registry-dispatch as a third architectural pattern (R50 DRAFT) for MCP servers, sibling to two-layer (R45) and all-in-one-class (R49). AWS MCP v4.0.0 / Bible v19.1.10 upgrade is complete on a feature branch (PR #8) and ready for AJ to merge + cutover. Pair status: DRAFT — flips to SIGNED post-cutover when 17/17 Phase 9 gate passes + R32 census returns 0 TRUE_BUG. Skill+tool union now provides complete AWS coverage with zero ambiguity (counts reconciled to 3,006 module-level functions across all artifacts) and zero compromise (universal CLI fallback covers all 400+ AWS services regardless of structured-tool coverage).

Rationale

10-phase Bible v19.1.10 Operational Playbook executed. install_annotator (R33+R41-R44), Contract Enforcer (G6), G8 redact processor, /health v2 with framework + contract surfaces, 10 net-new services + 5 R48 composites, registry-dispatch audit script (clean 3,006 functions), guardrail tests + Census harness all authored and pushed. Three residual ambiguities identified via metacog premortem and fixed (Pairing Contract count drift, skill count inconsistencies, baseline census documented as not-run). Production cutover blocked at Phase 9 per Auto Mode safety — AJ approval required for live deployment.
