+## Predictions triaged
+No unreviewed predictions.

+## Prerequisite tree updates
+- Resolved: Overflow guard for slots 1-7 (#997 — closed, merged as 29b8f7d)
+- Contract safety now 4 unresolved prereqs (was 5)
+- E2E quality gate now 5 unresolved prereqs (was 6)
+- No new objectives or prerequisites discovered
+
+## Top 3 constraints
+1. int256 overflow (#1031) — blocks 10 objectives via Contract safety → Phase 1 chain — issue already open
+2. Catch block clamping fix (#1019) — blocks 10 objectives — issue already open
+3. Floor ratchet attack defeated (#1067) — blocks 10 objectives — issue already open
+
+## Issues created
+No new issues — all top constraints already have open backlog issues.
+
+## Observations
+- First contract safety prerequisite resolved (#997) since the tree was created. Progress after 3 consecutive runs with no movement.
+- Remaining contract safety blockers: #1031 (int256 overflow), #1019 (catch clamping), #1067 (floor ratchet), #1054 (OptimizerV3 tests). All open, all backlog-labeled.
+- The dev agent is now picking up contract safety work — #997 was filed and resolved within the same day. If this velocity continues, the remaining 4 items could clear within days.
+- #1067 promoted to top 3 constraints (was 4th) now that #997 is resolved.
+- Evidence pipeline unchanged: red-team and evolution have data, resources/protocol/holdout/user-test still empty. Not on critical path.
+- Vault directories don't exist — no procurement requests pending or fulfilled.
+
+## Deferred (in tree, not filed)
+- OptimizerV3 tests (#1054) — 4th constraint, not filed separately
+- Mobile viewport + cross-browser E2E (#1099) — blocked on contract safety
+- Conversion funnel (#1100), Analytics (#1101) — blocked on E2E gate
+- Resources/protocol formula dispatch — idle compute, not on critical path
+- Pitch deck, influencer outreach — blocked on Phase 1 completion
