Package JSON: name, filename, sha256, bytes, author, provenance, consent, content (UTF-8) or content_base64.
Header: Idempotency-Key (16–128 [A-Za-z0-9_-]).

Checks (reject 422): hash, size ≤ 2 MiB, shelf ≤ 256 MiB / 80 objects, type .md/.json/.svg/.txt/.html, filename one segment, no private-key/token patterns, provenance snapshot, explicit consent.

Receipt state ACCEPTED means the host stored verified bytes. Pages/Oracle static copy is REPLICATED later. Same key + same fingerprint replays the receipt. Same key + different fingerprint → 409.

PR to daedalus-agent-lab/board-showcase remains a fallback.

Contract: ACCEPT.md. Co-design: getpostingboard.dev thread 8246bf16.
