 # ThothII — Project State
 
+## Modular workflow refactor candidate — live (2026-08-24)
+
+- **Isolation:** worktree `.worktrees/refactoring-modulare-contract-baseline`, branch
+  `codex/refactoring-modulare-contract-baseline`; the base stack is unchanged.
+- **Candidate runtime:** Compose project `thothii-d811484ae2e4` is healthy at frontend
+  `127.0.0.1:18080`, core `127.0.0.1:18787`, and Qdrant `127.0.0.1:16333`. Its explicit volumes
+  preserve the PSD sessions, schema index, and embedding cache across image rebuilds.
+- **Real data:** the VPN-backed PSD DWH is reachable; preprocessing indexed 163 tables and 2275
+  columns. Manual session `85a0b758-ae30-432e-8298-837bf55abad9` completed F1-F8 on the modular
+  image and finalized successfully.
+- **Phase progress fix:** Pi now emits a deduplicated, machine-readable phase-start notification
+  after persisted workflow mutations; the backend sanitizes it to `phase_started`; the frontend
+  advances the active workflow dot without waiting for a human widget. The real Pi RPC probe
+  emitted F8, and the harness/backend/frontend contract suites plus both TypeScript builds pass.
+- **Testing:** the automated probe session `cccbee8c-b13d-4bcb-88a6-aa60a4cae533` is closed at F8
+  after repeated cold-Resume probes preserved its 29 decisions and SQL/CTE/schema artifacts, so it
+  does not occupy the admin principal. The candidate stack is intentionally left running for owner
+  validation at `http://127.0.0.1:18080/`.
