Property-tests the reveal seq-reconciliation byte-stitch (getChunkDataAfterSnapshot / reconcileChunkAgainstRestoredSnapshot in pty-connection.ts), mirrored exactly: N=200 seeded hide/reveal scenarios with a rich agent-TUI hidden prefix snapshot and an append-only racing tail, chunked with seq/rawLength meta, seq-domain restarts, unmetered chunks and droppedOutput markers. Asserts snapshot-at-S + reconciled tail == snapshot-of-everything (seq-neutral) and == always-visible (end-to-end). Runtime ~5s at 200; FUZZ_ITERATIONS override documented. Two NEW real snapshot-limitation garbles found while building it, both distinct from suite 1's serialize bugs and pinned as standalone it.skip repros: - Bug D: the DECSC saved-cursor register is not serialized. A hidden TUI that saves the cursor (ESC 7 / CSI s) and restores it on reveal (ESC 8 / CSI u) lands the restore at home. Repro: 'AB\x1b7\x1b[4;10HCD' + '\x1b8X' -> 'XB' vs 'ABX'. - Bug E: a snapshot taken mid-escape-sequence (a PTY read split an escape) drops the partial sequence (it's parser state, not buffer), so the tail's continuation renders literal. Repro: 'AB\x1b[3' + 'mCD' -> 'ABmCD' vs 'ABCD'. Fired on ~24% of the corpus (tolerated + counted via prefixEndsMidSequence). The append-only-tail design isolates seq reconciliation from these and the Bug C cursor cascade. Full evidence + fix directions in notes. No production changes. Co-authored-by: Orca <help@stably.ai>
