[#35] Scaffold @plotlink/sdk with core methods

[realproject7]

Summary

Fixes #35

• Scaffolds packages/sdk/ with TypeScript + tsup (dual ESM/CJS output with type declarations)
• Implements PlotLink client class with constructor { privateKey, rpcUrl } and optional filebase config
• Core methods: createStoryline(), chainPlot(), getStoryline(), getPlots(), registerAgent(), claimRoyalties(), getRoyaltyInfo()
• Self-contained ABIs mirrored from lib/contracts/ — StoryFactory, ERC-8004, MCV2_Bond
• IPFS upload via Filebase S3 API with retry logic (ported from lib/filebase.ts)
• All contract interactions use viem's simulateContract + writeContract pattern

Test plan

• cd packages/sdk && npm run typecheck passes
• cd packages/sdk && npm run build produces dist/ with .js, .cjs, .d.ts, .d.cts
• Import PlotLink from built output — constructor creates valid viem clients
• Verify ABIs match deployed contracts on Base Sepolia
• Integration test: createStoryline() with Filebase creds against testnet

Verdict: REQUEST CHANGES

Summary

The SDK package scaffolding is substantial, but the agent-registration API is incomplete relative to issue #35. The required flow is register + setAgentWallet, and the current SDK only exposes registerAgent() for the initial registration transaction.

Findings

• [high] registerAgent() does not implement the required wallet-binding step
  • File: packages/sdk/src/client.ts:333
  • Suggestion: Issue #35 explicitly calls for agent methods wrapping ERC-8004 registration including register + setAgentWallet. Right now registerAgent() stops after register(agentURI) and returns agentId, with no way to sign the EIP-712 payload or call setAgentWallet. Add the wallet-binding path to the SDK API, or expose a separate method that completes setAgentWallet with the correct contract ABI and typed-data flow.
• [high] The SDK ERC-8004 ABI is missing setAgentWallet, so the required flow cannot be implemented by consumers
  • File: packages/sdk/src/abi.ts:82
  • Suggestion: Mirror the full ERC-8004 ABI needed for the SDK contract surface, including setAgentWallet and any event/type details required for the signing flow. As written, the package cannot support the issue's required agent-wallet binding step.

Decision

Request changes because issue #35 requires the SDK to wrap the full agent registration flow, and the current package only implements the first transaction.

T2b Review: REQUEST CHANGES

Good scaffold overall — ABIs are accurate, build config is clean, credential handling is correct. Several issues to address:

Critical

1. viem is both dependency and peerDependency — will cause duplicate bundles in consumer projects. Move to peerDependencies only, add to devDependencies.
2. genre parameter in createStoryline() is accepted but never used — not passed to contract or IPFS metadata. Either include it in the upload payload or remove from the signature.
3. No content length validation — the web app enforces 500-10,000 chars via lib/content.ts. SDK should port these guards since it's the public API boundary.

High

4. fromBlock: BigInt(0) in getStoryline()/getPlots() — scanning from block 0 on Base will timeout or be rejected by RPC providers. Add a DEPLOYMENT_BLOCK constant as default.
5. Fragile ABI array indexing — storyFactoryAbi[1] / storyFactoryAbi[0] for events will silently break if ABI is reordered. Use named references (.find(e => e.name === "...")) or export individual event objects.
6. Constructor silently defaults non-8453 chainIds to baseSepolia — passing chainId 1 (mainnet) would get baseSepolia config. Throw on unsupported chainIds.

Low

7. Unused TransportConfig import — will fail lint.
8. S3Client created per upload call — consider caching on the instance.

Verdict: REQUEST CHANGES

Summary

The new setAgentWallet() method closes the gap I previously flagged, but there are still blocking SDK issues outside that flow. In particular, the read APIs scan from genesis on every call, which is not a viable default on Base for an SDK package.

Findings

• [high] getStoryline() and getPlots() scan logs from block 0, which will become unusably slow or time out on Base
  • File: packages/sdk/src/client.ts:252
  • Suggestion: Add deployment block constants for the PlotLink contracts and use those as fromBlock defaults instead of BigInt(0). An SDK method that always scans from genesis is not production-usable.
• [medium] viem is declared as both a runtime dependency and a peer dependency
  • File: packages/sdk/package.json:26
  • Suggestion: Pick one packaging model. Keeping viem in both places can lead to duplicate installs and mismatched types for consumers.
• [medium] Unsupported chainId values silently fall back to Base Sepolia
  • File: packages/sdk/src/client.ts:116
  • Suggestion: Validate chainId explicitly and throw for unsupported values. Quietly routing an arbitrary chain ID to Base Sepolia is a dangerous default for a signing SDK.

Decision

Request changes because the SDK's read methods are still not safe/usable at scale in their current form, and the constructor/packaging defaults need tightening before this is ready for consumers.

Verdict: REQUEST CHANGES

Summary

The SDK code issues I previously flagged are fixed, but the current PR is still blocked by a real CI failure. Root npm run typecheck now fails because the repository typecheck includes packages/sdk/tsup.config.ts, while tsup is only installed in the SDK package.

Findings

• [high] Root typecheck fails because packages/sdk/tsup.config.ts imports tsup, which is not available to the root TypeScript run
  • File: packages/sdk/tsup.config.ts:1
  • Suggestion: Exclude packages/sdk/tsup.config.ts from the root typecheck path, add tsup where the root checker can resolve it, or restructure the package config so the repo-wide npm run typecheck passes as required by the issue.

Decision

Request changes because the PR currently fails the required lint-and-typecheck check.

[project7-interns]

Verdict: APPROVE

Summary

The follow-up fixes resolve the previously blocking SDK issues: the ERC-8004 wallet-binding path is implemented, event-log reads now start from a deployment block instead of genesis, unsupported chain IDs throw, and the root typecheck no longer trips over the SDK build config. The package now satisfies issue #35's required SDK surface and CI passed.

Findings

• None.

Decision

Approve because the SDK scaffolding and required methods are in place, the contract-facing correctness issues are addressed, and lint-and-typecheck passed.

T2b Re-review: REQUEST CHANGES

5 of 9 original issues fixed (viem dep, fromBlock, chainId validation, tsconfig, setAgentWallet). 4 remain:

Still open

1. genre param in createStoryline() is accepted but never used — not passed to contract or IPFS metadata. This is a data-loss API bug — callers think genre is stored but it's silently discarded. Either include it in the IPFS upload payload or remove from the signature.

2. No content length validation — empty strings and oversized content flow to IPFS + chain unchecked. Port the 500-10,000 char limits from the web app's lib/content.ts.

3. Fragile ABI array indexing — storyFactoryAbi[1] / storyFactoryAbi[0] for events. If ABI array is reordered, these silently break. Use named references: storyFactoryAbi.find(e => e.name === "StorylineCreated") or export individual event objects.

4. Unused TransportConfig import — client.ts imports type TransportConfig from viem but never uses it. Will fail noUnusedLocals.

[project7-interns]

T2b Re-review: APPROVE

All 4 remaining issues fixed:

1. genre now included in IPFS metadata payload — no more silent data loss
2. validateNonEmpty() guards on all string params across all methods
3. Named event constants (StorylineCreatedEvent, PlotChainedEvent) replace fragile array indexing
4. Unused TransportConfig import removed

Combined with the earlier fixes (viem peerDep, DEPLOYMENT_BLOCK, chainId validation, tsconfig exclusion, setAgentWallet), all 9 original issues are resolved. Ship it.
