Scope

Isolated executor migration only. The read-only CLI/MCP core is unchanged.

Implemented

• migrate executor target from @polymarket/clob-client-v2 to unified @polymarket/client 0.9.x
• preserve Ethers v5 wallet compatibility through the official signer adapter
• attach the existing Builder Code per limit order under the unified SDK
• preserve dry-run default, explicit EXECUTOR_LIVE=1 gate, and $10 default notional cap
• align GTD local preflight with the unified SDK's 180-second minimum expiry
• preserve secret redaction and the existing injected-client safety-test seam
• keep the legacy-shaped RawOrderClient seam so pre-migration safety tests remain applicable
• add a read-only builder-status probe for current builder fee rates + first page of attributed trades; no wallet keys required
• regenerate and commit executor/package-lock.json from a Node 24 GitHub runner

Final CI evidence — 2026-09-09

Branch push run 34304270876 on head a9d6fb586634ca11dcdcf575d3599b31c9786d82:

• Node 24 setup: PASS
• immutable npm ci: PASS
• unit tests: PASS
• TypeScript typecheck: PASS
• dry-run builder attribution: PASS
• workflow permissions restored to contents: read; no branch-write/auto-lock step remains

Earlier lock-generation run 34304136232 also passed and created commit 5174c523342132a54c1cf8f911a04dda7c04ad90 (chore(executor): refresh package lock).

Deliberately not done

• no merge to main
• no live order, cancellation, signing, wallet mutation, or credential change
• no Builder Fee configuration change
• no self-trade or artificial attribution test
• no x402 deployment

Remaining business/runtime verification before live use

• run the read-only builder-status probe against Polymarket's live service when a runtime can reach clob.polymarket.com; current Chat/web environment cannot safely resolve the direct API URL, so do not infer fee=0 or no attributed trades
• verify any custom-host requirement before removing or retaining legacy EXECUTOR_HOST; unified SDK production environment should remain canonical unless there is a real operator requirement
• first real attribution proof must come from bona-fide third-party order flow, not Leo self-trading

Merge boundary

Engineering migration is green. Keep this PR Draft until Leo explicitly approves merging the public repo change; live execution and Builder Fee activation are separate later approvals.
