feat[oz-retainer-07]: add automatic Polymarket report callback

[md0x]

Audit remediation feature

The Polymarket V2 integration expects UMA settlement to trigger OOReporterModule.report(requestId). The audited reporter currently only stores the raw UMA outcome, leaving reporting to a separate transaction.

References: FRO-108 · audited scope tag

Resolution

• Add an integration hook after a final non-P4 outcome is stored.
• Add PolymarketOOReporter, which calls report(requestId) on the module that registered the request.
• Commit resolved state before the external call so the module can read the outcome during reporting.
• Wrap reporting in try/catch so a downstream revert does not block Managed OO settlement; emit ReportCallbackFailed for permissionless retry.
• Skip reporting for P4, stale, unknown, and already-resolved callbacks.
• Keep payout translation and finalize() in the Polymarket contracts.
• Enable the package optimizer so both reporter implementations remain below EIP-170.

Validation

• cd pm-v2-oo-reporter && forge fmt --check
• cd pm-v2-oo-reporter && forge test — 43 tests passed
• cd pm-v2-oo-reporter && forge build --sizes --force — PolymarketOOReporter 14,847 bytes
• git diff --check

Reviewed against FRO-108 and the live Polymarket module contract. Reporter state is committed before the external callback, callback failure is isolated for permissionless retry, and P4/stale/unknown/already-resolved paths do not report. The base storage/external ABI remains unchanged and the integration boundary is documented.

looks good!

[chrismaree]

if this succeeds do we want to also emit something? like ReportCallbackSent or something like this?

Good point. Since OOReporterModule is Polymarket-owned, our reporter should expose its own success signal rather than rely on downstream events. I added ReportCallbackSucceeded, emitted only after report(requestId) returns without reverting.
