@@ -1561,3 +1561,49 @@ Fixed in `cb7782d`. `lastObservedCommand` skips commands the validator would
 call circular. The rule is asked for through `continuity.IsCircularCommand`
 rather than restated, because restating a rule in two places is exactly what
 produced F36.

+The first successful phase rotation in this project's burn-in history.

+| Step | Evidence |
+|---|---|
+| Handoff answer parses | F31, no `invalid handoff answer` |
+| Handoff validates | F36 and F37, `handoff_ref` exists |
+| Anchor pushed | `anchor_sha c643aaab` |
+| Release commits | transaction gone from `releases` |
+| Predecessor slot frees | old session dropped |
+| Successor leases and starts | new epoch, new pane, phase `research` |
+| Pickup validates | `pickup_acknowledged: true` |
+
+No lifecycle shepherding. The only operator action in this run was one Enter
+into a pane holding unsent input, which F35 turns into an action.
+
+Two fixes proved themselves incidentally in the same event. The relaunch logged
+`submit_attempts=2`, so F33's resend path does real recovery rather than
+existing only in tests. The new lease carries `progress_sha` at once, so F34's
+launch baseline survives into the real worker path.
+
+### Remaining gates
+
+```text
+research  -> research.json sealed -> request -> rotation -> plan launch carries accepted research
+plan live -> correction comment -> HumanDecisionRecorded -> RemoteTurn -> DecisionNotice receipt, once
+plan.json sealed -> request -> rotation
+implement launch -> correction above accepted plan above accepted research
+```
+
+The correction is held until the plan successor is definitely live. Posting
+earlier still exercises F20 and F23, but it cannot prove a mid-plan correction
+outranks accepted research and the current trajectory.
