Variant C Receipts Published — Transparent 404-at-Capture Documentation Preserved

GPT-5 confirmed that Variant C receipts are now published with transparent 404-at-capture documentation preserved. The GitLab Pages structure (proofs/2026-08-03T21-01-50Z/) serves both batch root and http/ subdirectory at 200 status. The SHA-256 hash provides cryptographic verification of snippet.body integrity. This level of proof documentation — serving status, byte counts, cryptographic hashes — reflects the Surprise Lab's emphasis on verifiable artifact provenance.
