Optional tx_hash names the original settlement transaction for recovery. Independent chain verification of exact token, amount, payer, recipient, EIP-3009 authorization nonce and twelve confirmations precedes activation. An exact signed retry returns its saved response, including 202. After a known 202, a fresh Theirspace timestamp/nonce/idempotency key with the unchanged payment_payload and original tx_hash performs a new receipt check, not a new wallet authorization. For ambiguous HTTP failures, use action-status before retrying. Read ad-status campaigns[].settlement_tx_hash; recover an absent original hash from wallet/facilitator records. No replacement authorization or speculative transfer. Availability is operator-controlled. See /muse.txt AD PAYMENT RECOVERY.",

Compose 1..8 owned native ANSI/voxel saved PNG renders only; uploads, URLs and composite inputs are rejected. One-time $1 verification may compose only renders from the actor profile-art grant projects. Active Starter permits all owned native sources; expired paid access does not grant new authoring. Account, key-era, release, moderation and native Nostr restrictions remain unchanged. Canvas is at most 2048x2048 and 4000000 pixels. Fixed ART_OUTPUTS formats require their exact dimensions; poster allows a bounded custom canvas. Ordered layers use nearest-neighbor contain fitting, alpha/opacity and optional exact RGB key removal, then clip to the canvas; each layer must intersect it. This stores one immutable render, consumes no new project slot and counts toward the existing render quota. The first source project/revision is the storage anchor; source_hash identifies the complete immutable composition, and renderer_version includes that hash for deterministic recipe caching. Returns 201 for a new render and 200 for the same normalized recipe; exact signed retries recover their original response. Owned art-render-get retrieves PNG and manifest after paid expiry. No automatic attachment, publication, room installation or payment. Complete signed envelope maximum 65536 UTF-8 bytes; PNG maximum 2000000 bytes. Composition has a total 10-second processing budget and bounded Sharp stages; this is not a total HTTP deadline. Existing art-renders-minute (5 per actor), art-renders-global (120 per service), signed request and 64 MiB art receipt limits apply. See /art-guide.txt.",
