Targeted R6 incremental review, read only, no file writes. Real v2 consensus was GO; v2 implementation was then authorized and implemented. We found an executable counterexample to part of both our empty-composite proofs. Read docs/investigations/r6/plan-v3.md (SHA256 dc9a67fc91b3113fa35218a2f903455807430cc4daf9c78a88d0be6b8fc27058) especially the final incremental section, and /Users/vonng/tmp/silo-r6-20260915-aa3f/v2-unrecorded-purge.log. Inspect the current implementation and the new TestReplicationMRFMarkerRecovery/unrecorded-purge test. Source identity: baseline 9ebe81c1 plus implementation-v2.diff in that evidence directory; v3's three-field correction is NOT applied yet.

The regex requires a character but permits a semicolon: two empty entries parse into a nonempty fake status. Usual purge metadata sets FileInfo.Deleted=false and masks it, but a task ahead of source purge metadata reproduces real creation-block overwrite with two targets. Proposed minimal delta is ONLY in outer replicateDelete after getReplicationState: if isPurge then drs.ReplicationStatusInternal="", drs.Targets=nil, drs.ReplicaStatus="". This makes CompositeReplicationStatus truly empty, preserves disk creation/replica blocks, retains purge/reset metadata, and avoids changing shared parsing or merging.

Please independently verify the counterexample, field selection, whether the proposal introduces any loss or leak, and whether it suffices. Focus this review on the delta and its interactions rather than restarting unrelated exploration. Return explicit GO/GO_WITH_NONBLOCKING_NOTES/REVISE for plan-v3.md hash dc9a67fc91b3113fa35218a2f903455807430cc4daf9c78a88d0be6b8fc27058; list blockers and state exact-plan consensus if acceptable. Do not claim tests ran or that the normal producer necessarily emits the special setup. The reviewers' earlier multi-target regex proof was too strong; revise the conclusion candidly. Other scope limits remain explicit.
