 `foldDegraded` is gone from `ConversationSnapshot`, and with it the padding sentinels, the `baseSeq` arithmetic they needed, and `degradedSeqs()`. They existed only to satisfy the core fold's `seq === index` assertion and to survive its throw; the fold they describe is no longer run. Deleting the flag is part of the fix, not cleanup after it — `degradedSeqs()` was already almost the log-ordered projection, reached after a thrown error instead of intended.

-The marker's summary text, replaced-item count, and estimated shadowed-token count come from the checkpoint's own `compact/summary` provenance, never from the framed checkpoint payload, which is an instruction envelope written for the model. A window cut that left the provenance outside makes those fields unavailable, the same soft-fall as a call-less tool result, and a later page supplying the provenance resolves them.
+The marker's summary text, replaced-item count, and estimated shadowed-token count come from the checkpoint's cited `compact/summary` event, never from the framed checkpoint payload, which is an instruction envelope written for the model. A window cut that left that event outside makes those fields unavailable, the same soft-fall as a call-less tool result, and a later page supplying the event resolves them.

 The [manual compaction command](../feature/2026-07-30-queued-manual-compaction.md) returns the summary event's seq as the successful `CommandResult.sourceEventSeq`, and `command/done` persists that optional reference. Chat pairs only a successful named `/compact` command whose reference equals exactly one loaded `CompactionSummaryNode.summaryEventSeq`. The running command first renders `compact · Compacting context…`; after the checkpoint lands, the same React key renders one collapsed `compact` disclosure at the checkpoint's flow position with the count and token estimate. Input rejection, no compactable history, cancellation, and failure remain generic command rows with complete handler-authored text. Automatic compaction has no command reference and keeps the standalone context-compacted marker.
