Summary

CI currently fails on every PR (e.g. #781, #783) before any test runs. The workflow installs Foundry stable, and releases after the last green dev run (Oct 2025) break this repo:

• Build: the post-build lint step added in newer Foundry crashes resolving an import inside lib/deterministic-factory (file src/interfaces/IDeterministicFactory_v1.sol not found, "internal lint engine failure (compilation itself succeeded)"). compile fails, and the other jobs fail because the compiled-artifacts artifact is missing.
• Formatting: newer forge fmt reformats imports across the whole codebase, so verify-formatting would fail on untouched files too.

Separately, test_e2e_LM_PC_KPIRewarder_v2Lifecycle was broken:

• It minted Sepolia USDC by impersonating a minter that can no longer mint (FiatToken: caller is not a minter).
• It passed address(0x1) as the asserter, but since the Hats audit fixes ([Audit] Merging Hats Fixes into Dev #607) the bond is pulled from the asserter, so posting the assertion reverted with InsufficientFundsToPayForBond.

Changes

• .github/workflows/ci.yml: pin foundry-toolchain to v1.3.6 in all jobs, the newest release that builds without the lint crash and passes the existing format check unchanged.
• test/e2e/logicModule/KPIRewarderLifecycle.t.sol: fund the test contract with deal instead of minting, use the automation service as asserter, and approve the bond from it (unlimited, since every round posts a bond).

Deployment Steps

✅ No deployment steps required. CI and test only.

Test Plan

Pre-merge checklist

• With Foundry v1.3.6 locally: forge build, make check-size, forge fmt --check, make testScripts all pass
• forge test: 1570 passed, 0 failed (previously 1 failed: the KPI e2e test)
• CI green on this PR
