Conversation
…ty model (proved) + TLA+ store Post-ratification deliverables (author-approved). - docs/spec/ROADMAP.md — phased development plan (Phase 0 scaffold → 1 prove the waist P1→P2→P0 → 2 ceremonies → 3 client libs → 4 BVP store), with the decided/held gate and per-phase exit criteria. - ADR 0020 — Authority = Effect × Assurance × Scope (product meet-lattice); rejects the linear verdict lattice. OB-12. - ADR 0021 — store append CAS now, Byzantine Vertical Paxos next (wedge/ reconfiguration; ref Abraham-Malkhi DCCL / Lamport-Malkhi-Zhou). OB-15. - ADR 0022 — signed-object grammar: one constructor, protected tuple, genesis STORE_ID_SELF. OB-13/OB-14. - ADR 0023 — the three-tier proof discipline (Lean+Aeneas / Tamarin-ProVerif / assumed crypto + conformance vectors). - formal/lean/Authority.lean — mathlib-free, COMPILES (exit 0), 25 theorems, 0 sorry: meet laws, attenuation (L4/PO-4), no-fail-open (OB-9/OB-12), order-independence (L1/PO-1). The Tier-3 algebra half, machine-checked. - formal/tla/CeremonyStore.tla — CAS append + anti-rollback state machine; invariants map to PO-2/2a/2c + OB-15/OB-16 (CAS-loser benign; checkpoint monotone; no rollback). - formal/README.md — how to check both, and why two tools. Nonbinding formal spikes per review-7; no wire structs frozen. Merge/implement of code remains gated on conformance vectors (Phase 1d).
