[#160] Fix getRoyaltyInfo ABI mismatch

[realproject7]

Summary

• getRoyaltyInfo on the deployed MCV2_Bond takes (address token, address beneficiary) → uint256, not (address token) → (uint256, address) as previously assumed
• Updated ABI definitions in lib/price.ts, packages/sdk/src/abi.ts, and packages/sdk/src/client.ts
• WriterTradingStats and ClaimRoyalties now fetch the bond creator via tokenBond() and pass it as the beneficiary
• CLI claim and status commands updated to use the correct 2-arg signature

Fixes #160

Test plan

• tsc --noEmit — zero errors
• next build — clean
• vitest run — 22/22 tests pass
• Verify on Base Sepolia: getRoyaltyInfo(token, creator) returns unclaimed amount
• Verify writer dashboard shows earnings instead of "—"
• Verify ClaimRoyalties button appears when royalties are available

T2b APPROVE

Reviewed all 8 files. The ABI correction is consistent across all layers:

1. ABI definitions (lib/price.ts, sdk/abi.ts) — Both updated to (address token, address beneficiary) → uint256. Consistent.

2. SDK client (client.ts) — getRoyaltyInfo now takes beneficiary param, returns { unclaimed }. RoyaltyInfo interface updated. Clean breaking change.

3. CLI (claim.ts, status.ts) — Both fetch tokenBond() first to get creator, then pass as beneficiary. Good restructuring in claim.ts to avoid duplicate tokenBond calls.

4. Web components:

   • WriterTradingStats — Correctly splits into two dependent queries with enabled guard.
   • ClaimRoyalties — Accepts beneficiary prop, includes it in query key for proper cache invalidation.
   • writer/page.tsx — Threads writerAddress down as beneficiary. Safe since the dashboard only shows the connected wallet's storylines.

No issues found.

Verdict: APPROVE

Summary

The PR corrects the deployed getRoyaltyInfo(token, beneficiary) ABI across the app, SDK, and CLI, and updates the affected royalty reads to supply the beneficiary address. I did not find any remaining one-argument callers, and CI is passing.

Findings

• [info] No remaining blocking findings.
  • File: packages/sdk/src/client.ts:500
  • Suggestion: None.

Decision

Approving because the ABI mismatch is fixed consistently across the relevant surfaces, the writer dashboard royalty reads are restored, and the required lint-and-typecheck check is green.
