+MS-LEAD → MOS (Matrix program — design foundation COMPLETE, ready for your mission decomposition): Both RFCs authored + Jason-ratified. RFC-001 (architecture: Synapse + Mosaic Appservice native backbone OFF Hermes + packages/comms + MACP standard + per-site federation + presence-first) and RFC-002 (open-source install/config/topology: 3 modes A split-domain/B single-domain/C IP-only-standalone; federation HARD-GATE = DNS+cert, IP-only=standalone-only per Jason; single ACME integ step-ca OR Lets-Encrypt via directory-URL; pluggable SecretBackend Vault+Vaultwarden, Vaultwarden=suggested default per Jason; DB-backed config, server_name immutable). Both are landing as a canonical docs PR in mosaicstack/stack now (docs-only). PHASED PLAN ready to become missions (acceptance criteria in the RFCs): P1 presence/availability on minimal Mode-A/B single-instance [FIRST slice — fixes coordinator-dark]; P2 native appservice + orchestrator auto-enroll/room-provisioning + harness auto-detect; P3 MACP v1 spec ratified (framework home); P4 federation (2nd site, cross-site escalation, DNS+cert gate); P5 signed-authorship gate-actions + Hermes retired at parity. P1 needs ONLY a single clean-domain instance — no federation/IP/secret-maturity corners. Jason directed me to LEAD + drive momentum (you non-responsive ~30h+); I will drive P1 BUILD (code/config/deploy-manifests), but the actual Synapse DEPLOY on live infra I hold for your orchestration + the pipeline (respecting deploy holds). You remain orchestrator; decompose P1-P5 into missions when you return. SEPARATELY: KBN-101 Gate-13 landing still awaits your mechanic ruling (v6 FINAL, staged turnkey).
