Set Stone metadata returns 404 - contract baseURI mismatches deployment

[magent-cryptograss]

Problem

The Set Stone contract on Arbitrum (0x39269b3FddFc9bf0626e5CFe4424aa51A77f7678) has a baseURI of https://justinholmes.com/setstones/ but no metadata is being served at that location.

Current state:

• Contract baseURI(): https://justinholmes.com/setstones/
• Contract tokenURI(1): https://justinholmes.com/setstones/1
• Actual response: 404 Not Found
• Stones minted: 5

Root Cause Analysis

The build system generates JSON metadata to {outputDir}/setstones/{tokenId} (see src/build_logic/setstone_utils.js:217), but:

1. The contract was deployed with justinholmes.com as the base, not cryptograss.live
2. Even https://cryptograss.live/setstones/1 returns 404 - the JSON isn't being deployed to production

The metadata generation code exists and produces valid ERC721 metadata:

const metadata = {
    name: `Set Stone for show ${showId}`,
    external_url: `https://justinholmes.com/cryptograss/bazaar/setstones/${showId}.html`,
    description: `Set Stone from artist with id=${show.artist_id} and show on ${show.blockheight}`,
    image: `https://cryptograss.live/assets/images/setstones/${set.shape}-${color1}-${color2}-${color3}.png`,
    attributes: [...]
};

Impact

• OpenSea, Rarible, and other marketplaces cannot display Set Stone NFTs properly
• No images, names, or attributes visible on marketplaces
• NFT explorers (Arbiscan) show broken metadata

Proposed Solutions

Option A: Fix deployment to match contract

1. Configure web server to serve JSON from justinholmes.com/setstones/
2. Ensure build artifacts are deployed to justinholmes.com
3. Verify Content-Type headers return application/json

Option B: Update contract baseURI (if possible)

1. Check if contract has setBaseURI() function
2. Update to https://cryptograss.live/setstones/
3. Ensure cryptograss.live deployment includes the JSON files

Option C: Server-side redirect

1. Add redirect from justinholmes.com/setstones/* to cryptograss.live/setstones/*
2. Ensure cryptograss.live serves the JSON

Files Involved

• src/build_logic/setstone_utils.js:183-217 - Metadata generation
• src/build_logic/primary_builder.js:356 - Build invocation
• src/build_logic/constants.js - Contract address
• src/abi/setStoneABI.js - Contract ABI (check for setBaseURI)

Acceptance Criteria

• curl https://justinholmes.com/setstones/1 returns valid JSON metadata
• JSON includes correct image URL that resolves to actual PNG
• OpenSea can index the collection and display token images
• All 5 minted tokens have accessible metadata
