REVIEWED — 049 MACW MESSAGE-WALL AUGUST ARCHIVE CHECK
Completed 2026-09-05 UTC. No independent historical capture of the message artifact was recovered. This does not negate the current artifact corroborated in report 043.

Scope and result
Looked up macw.cc and www.macw.cc in the CC-MAIN-2026-34 (August) zipnum index. Checked the ordinary www-stripped SURT host prefix cc,macw)/ and the literal-www variant cc,macw,www)/. Both complete host ranges lie inside the same index block, 57003; no adjacent block starts within either prefix. One index range GET therefore covered both requested host spellings and all indexed paths, including /message and /api/messages.
The decoded block contains 3,000 CDX records. There are ZERO records under either SURT prefix. An independent check of each decoded record's actual URL hostname also found ZERO macw.cc or www.macw.cc records. Consequently there were no WARC pointers to retrieve: zero archived frontend bodies, zero API responses, and zero matching message bodies were recovered. No independent August date anchor can be assigned to the 18 matching nickname messages or the Agent test from report 043.

Exact request coverage
One archive index GET; HTTP 206; no errors. No WARC pulls, no target-origin GETs, no authentication, no write actions, no embedded-link visits, and no execution of page code. The allowance of at most three index pulls plus two WARC pulls was not exhausted because there was no candidate record to pursue. No new corpus scan occurred.

Requests are paced with a 1.6-second interval; this run made only one network request.

Interpretation
The current /api/messages response in 043 remains positive evidence that the displayed nickname and Agent message test exist at the public destination now. This archive lookup supplies no creation date, authenticated identity, execution provenance or operator attribution. Absence from this single August crawl index is a coverage limitation, not evidence that the messages did not exist earlier. July, September, other archives and nonstandard host aliases were not searched here. The parent separately owns the Wayback check in 048.
A frontend-shell capture alone would not have been accepted as a message date anchor. The requested standard was an archived body containing the matching message; no such body was available from these index results.

Saved block-57003.gz, records.json (empty), metadata.json, coverage.json, and host-verification.json. The latter records range boundaries, 3,000 examined rows and the exact-hostname cross-check. The unrelated index rows remain private and are not copied into the report.
