Deploy + migration tasks for OrderBook → Raindex rename (#2526)

[thedavidmeister]

Tracking issue for the deploy and downstream-migration work needed around merging #2526 (OrderBook → Raindex rename).

The PR itself is code-complete with green CI and E2E sign-off. This issue covers everything outside the merge that has to happen for the rename to actually land in production.

Ordering

Roughly:

1. Pre/at merge — sub-parser + Goldsky subgraph deploys (from the PR branch, so consumers can cut over without a broken window).
2. At merge — merge Rename OrderBook to Raindex #2526; publish npm package.
3. Post merge — Vercel config; downstream config updates (strategies, external .rain files, API/JS consumers); user-side cache clear happens organically.

Pre-merge / gating

• Deploy new RaindexV6SubParser contract
  • Old address: 0xC17693a98370970D8Ec2d47d0cc37E847f035710
  • New address: 0x6E81D70fD7801Cf21DD177f82c2e5BCffb86321E (Zoltu deterministic)
  • New bytecode hash: 0x78d0f0b8b03d9e9e6cd09a013754032a57cb688a13a98cb130df43d282ead580
  • Why bytecode changed: the sub-parser embeds a string literal for the word it matches (WORD_ORDERBOOK = "orderbook" → WORD_RAINDEX = "raindex" in src/lib/LibRaindexSubParser.sol). The string is data baked into deployed bytecode.
  • The main RaindexV6 orderbook contract is NOT being redeployed. It stays at 0x7242ce1ffe34297921c54cD7f9343c411E1E7759. Pure Solidity identifier renames (OrderBookV6 → RaindexV6 etc.) don't change bytecode. GenericPoolRaindexV6ArbOrderTaker and GenericPoolRaindexV6FlashBorrower also unchanged.
• Deploy new Goldsky raindex-* subgraphs for arbitrum-one, matic, base, flare — run Deploy subgraph workflow on rename-orderbook-to-raindex branch (workflow already updated to GOLDSKY_SUBGRAPH_NAME: raindex). Full re-index from existing startBlock per chain, takes time. All four networks point at the unchanged main contract 0x7242ce1f…7759.

At merge

• Merge Rename OrderBook to Raindex #2526 once the above are deployed
• Publish new @rainlanguage/raindex npm package
• Coordinate npm publish — consumers must explicitly switch from @rainlanguage/orderbook to @rainlanguage/raindex (not an in-place upgrade)

Post-merge — config & downstream

• Verify Vercel project configs point to packages/raindex (not packages/orderbook)
• Update subgraph URLs in all strategy YAML configs to point at new Goldsky raindex-* endpoints
• Update external .rain strategy files: orderbooks: → raindexes:, orderbook: → raindex:, bump to version: 6
• Update external .rain source using the orderbook() word → raindex() (this is the user-facing effect of the sub-parser word literal change)
• Update any API consumers parsing old JSON field names (obId → raindexId, orderbookAddress → raindexAddress, "orderbook" → "raindex" on trade/order objects, "orderbook" field in TakeOrdersReadyResponse)
• Update any JS/TS code using the WASM API: OrderbookYaml → RaindexYaml, OrderbookYamlError → RaindexYamlError, getOrderbookByAddress() → getRaindexByAddress(), .orderbook() → .raindex() on RaindexOrder/RaindexVault/TakeOrdersInfo, .orderbookAddress → .raindexAddress on DeploymentTransactionArgs

User-side (organic)

• Users clear local DB cache — DB_SCHEMA_VERSION bumped 2→3, fresh sync required

Already done (per #2526 checklist)

• Rebuild remote DB dumps with new schema (raindex_address columns)
• Update rain.strategies registry to version 6 with raindexes: keys
• Update RAINLANG_URL in packages/webapp/src/lib/constants.ts to new strategies commit
• Merge Rename ob-yaml.md to raindex-yaml.md specs#52 (rename ob-yaml.md → raindex-yaml.md)
