[#10] Inline Indexer — Storylines

[realproject7]

Summary

• P1-5a: src/app/api/index/storyline/route.ts — POST endpoint for storyline indexing:
  1. Fetch transaction receipt
  2. Find StorylineCreated event by topic0 signature (not address)
  3. Decode event args (storylineId, writer, tokenAddress, title, hasDeadline)
  4. Get block timestamp via getBlock()
  5. Detect writer type via ERC-8004 (best-effort)
  6. Upsert to Supabase with (tx_hash, log_index) deduplication
• P1-5b: lib/contracts/erc8004.ts — ERC-8004 agent detection helper:
  • detectWriterType(address) queries agentIdByWallet() on the registry
  • Returns 1 (agent) if agentId > 0, else 0 (human)
  • Best-effort: defaults to 0 on any error

Fixes #10

Test plan

• tsc --noEmit passes
• vitest run — 22/22 passing (existing tests unaffected)
• Integration test on Base Sepolia with a real createStoryline transaction
• Verify ERC-8004 lookup works against the registry at 0x8004...432

Verdict: APPROVE

Summary

The PR matches issue #10 with a focused storyline indexer route and a minimal ERC-8004 lookup helper. The event parsing, timestamp lookup, best-effort writer type detection, and Supabase upsert behavior align with the ticket requirements, and CI passed.

Findings

• None.

Decision

Approve because the implementation stays within scope, follows the established inline indexer pattern, and I did not find a blocking correctness or schema issue in the added logic.

T2b Review: APPROVE

Storyline indexer — Follows PR #49 pattern exactly: txHash regex validation, receipt fetch, StorylineCreated decode via topic0 matching, block timestamp, Supabase upsert with onConflict: "tx_hash,log_index".

ERC-8004 helper — agentIdByWallet reverse lookup against the registry. Best-effort with correct fallback to 0 (human) on failure. BigInt comparison is correct.

Security — Input validation present, no secrets, server-side Supabase client with service role key from env.

Scope — Matches issue #10 exactly (P1-5a + P1-5b). No scope creep.

No issues found.
