This record explains the problem in plain language, the merge decision, two rounds of adversarial review, the source-timestamp and tombstone repair, S3 response cleanup, costs, rejected alternatives, historical follow-ups, and the release gate tracked by issue #75. https://silo.pgsty.com/blog/design/bucket-cors-wire-contract/ Sat, 29 Aug 2026 00:00:00 +0000 https://silo.pgsty.com/blog/design/bucket-cors-wire-contract/ SILO’s first per-bucket CORS implementation accepted a second XML root, counted UTF-8 bytes instead of characters in rule IDs, and normalized lowercase methods outside the S3 enum. This B3 design record fixes the wire/parser/validation contract, documents the AWS and browser evidence, records the rejected alternatives, and keeps site-replication work explicitly out of scope.
