@@ -2947,3 +2947,72 @@ The implement session kept working after the reopen. It verified phase-2
 against the old plan 40 seconds after the task had moved to `plan`. Harmless,
 because supersession discards it, but the reopen does not end the session that
 reported the contradiction. That session rotates at its own next boundary.

+## Run 21, 2026-08-29: F66 proven, in two rounds
+
+Tasks `06G4WW6TND26M16CZA6WE5T458` (issue 32, on `edf0076`) and
+`06G4XAFH1MBPC35VSJN7V3NS14` (issue 34, on `7539696`).
+
+### Round one failed, and the failure was in the fix
+
+`edf0076` projected the contradiction onto the task and rendered it into the
+plan-phase context. The projection appeared at the reopen and was gone before
+the planning session launched:
+
+```text
+16:58:01  PlanMismatchRecorded phase-2 replan, plan reopened
+          projection carries the contradiction
+16:58:20  TaskReleased          the rotation the reopen causes
+          projection empty
+16:59:29  replacement sealed, planner never told anything
+```
+
+The clearing rule added with F67 sits **below** the reducer switch, so it runs
+for every event rather than for the correction it was written for. A release
+found the task unblocked and erased the contradiction. Two mistakes made it:
+the rule was written as if it were inside `case "TaskCorrected"`, which is
+merely the nearest case above it, and the unit test read the projection at the
+moment it was written rather than at the moment the planner reads it.
+
+`7539696` scopes the clear to `TaskCorrected`, and the store test now walks the
+real sequence: mismatch, reopen, release, lease, then assert.
+
+### Round two: the planner is told what it was convened to fix
+
+```text
+18:00:17  PlanMismatchRecorded phase-2 replan, plan reopened
+          projection survives the rotation
+18:01:02  planning session launches
+```
+
+From that session's `.orchestra/launch.md`:
+
+```text
+## Why this phase reopened
+
+A plan was already accepted and the code contradicted it. Orchestra reopened
+this phase to settle that, and the session that found it is gone.
+
+- phase: phase-2
+- observed: The summary lines are printed from the recorded results after
+  every check has run, ...
+- the plan says: The plan states that phase 2 prints the header from a helper
+  that returns the number of checks about to run.
+- evidence: scripts/orchestra_e2e_healthcheck.sh:1
+
+The accepted plan stays accepted until you seal a replacement, and sealing one
+supersedes it along with every phase it had verified. Address the
+contradiction above: a replacement that repeats it will be contradicted again.
+```
+
+It renders above the sealed research and plan, because it changes how they
+should be read. The first planning session of a task carries no such section,
+and neither does implement. Sealing the replacement (`2edcbe9e`) cleared the
+projection, which is the other end of its lifetime.
+
+### The lesson worth keeping
+
+Both rounds of this fix passed their unit tests. What separated them was where
+the assertion sat in the sequence. A projection written correctly and read one
+rotation later is not the same claim, and only the live run put the read where
+the agent does.
