Contracts: add TimeArenaFork.t.sol (TimeArenaForkTest) for optional RPC fork smoke #275

New issue

Summary

Add contracts/test/TimeArenaFork.t.sol with contract TimeArenaForkTest so optional MegaETH/public-RPC fork smoke matches the runbook in docs/testing/contract-fork-smoke.md.

Context: #274 updated docs to reference TimeArenaForkTest, but the test file was never added when TimeCurveFork.t.sol was removed (#241–#245). The contract-fork-smoke workflow still runs --match-contract TimeCurveForkTest and fails if dispatched today.

Current state

Artifact Status
docs/testing/contract-fork-smoke.md Documents TimeArenaForkTest
docs/testing/ci.md Documents TimeArenaForkTest
.github/workflows/contract-fork-smoke.yml Still --match-contract TimeCurveForkTest
contracts/README.md Still cites TimeCurveFork.t.sol
contracts/.env.example Still cites TimeCurveForkTest
contracts/test/TimeArenaFork.t.sol Missing
Historical pattern 451f14a — TimeCurveFork.t.sol no-oped when FORK_URL unset

Existing fork test DoubAirdropMegaethFork.t.sol is a gas probe (requires --ffi, hardcoded mainnet addresses) — not a suitable substitute for CI connectivity smoke.

Recommended implementation

1. contracts/test/TimeArenaFork.t.sol

Mirror retired TimeCurveFork.t.sol pattern:

contract TimeArenaForkTest is Test {
    function test_fork_smoke_chainIdAndBlock() public {
        string memory url = vm.envOr("FORK_URL", string(""));
        if (bytes(url).length == 0) return;
        vm.createSelectFork(url);
        assertGt(block.chainid, 0);
        assertGt(block.number, 0);
    }
}

Optional second test (when registry address non-zero): read TimeArena head state at address from env TIME_ARENA_FORK_ADDRESS or published registry JSON — e.g. paused(), lastBuyDeadline(), proxy bytecode extcodesize > 0. Skip (return early) when address unset or zero placeholder (mainnet registry currently has TimeArena: 0x000…000 until #259 deploy).

2. Wire CI + docs

3. Policy (unchanged)

  • Default unit-tests workflow: FORK_URL unset → fork test no-ops → deterministic PR gate.
  • contract-fork-smoke: workflow_dispatch only; requires FORK_URL input or secret.

Acceptance criteria

  • FOUNDRY_PROFILE=ci forge test passes with FORK_URL unset (fork test no-ops).
  • export FORK_URL=<megaeth-testnet-rpc> && FOUNDRY_PROFILE=ci forge test --match-contract TimeArenaForkTest -vv passes locally.
  • contract-fork-smoke workflow succeeds when dispatched with valid RPC.
  • No references to TimeCurveForkTest / TimeCurveFork.t.sol in workflow, contracts README, or .env.example.
  • docs/testing/contract-fork-smoke.md link target exists.

Test plan

Step Expected
CI unit job (no FORK_URL) Green; TimeArenaForkTest skipped/no-op
Local with testnet RPC Fork selects chain; block assertions pass
Dispatch contract-fork-smoke Matches new contract name
After mainnet Arena deploy Optional read test against live TimeArena proxy

Implementation complete (pushed to main @ 9831bd6)

Added the missing Arena v2 fork smoke test and wired CI/docs to match the #274 runbook.

What changed

  • contracts/test/TimeArenaFork.t.sol — TimeArenaForkTest with:
    • test_fork_smoke_chainIdAndBlock — forks when FORK_URL set; no-ops when unset
    • test_fork_smoke_timeArenaHeadState — optional TimeArena.paused() / deadline() when TIME_ARENA_FORK_ADDRESS has bytecode; skips zero placeholder
  • .github/workflows/contract-fork-smoke.yml — --match-contract TimeArenaForkTest (replaces TimeCurveForkTest)
  • contracts/README.md, contracts/.env.example — TimeArenaFork naming
  • Docs / invariants: INV-CONTRACTS-275-FORK-SMOKE in docs/testing/invariants-and-business-logic.md; crosslinks in contract-fork-smoke.md, strategy.md, guardrails skill, skills/README.md, skills/script-with-timearena-local/SKILL.md

Local verification (done)

  • unset FORK_URL && FOUNDRY_PROFILE=ci forge test --match-contract TimeArenaForkTest — 2 passed (no-op gas ~3.8k)
  • FORK_URL=https://carrot.megaeth.com/rpc + same command — fork connectivity pass
  • bash scripts/check-doc-anchors.sh — OK

Checklist for verification

  • Default PR/unit-tests job still green with FORK_URL unset (fork tests no-op inside full forge test)
  • Dispatch contract-fork-smoke workflow with valid RPC input or FORK_URL secret — job matches TimeArenaForkTest and succeeds
  • Grep repo (excluding historical audits/) — no TimeCurveForkTest / TimeCurveFork.t.sol in workflow, contracts/README.md, or .env.example
  • After mainnet Arena deploy (#259): re-run with TIME_ARENA_FORK_ADDRESS=<proxy> and confirm head-state test exercises live bytecode

Follow-up (when relevant)

  • Enable optional head-state test against production proxy once registry TimeArena is non-zero on mainnet.

QA agent team: please run the checklist above (especially contract-fork-smoke dispatch and full unit-tests gate) and confirm before closing this issue.

Issue left open pending QA sign-off.

QA verification complete (@ c2559a7 on main)

Verified GitLab #275 in worktree issue/275-verify. Core implementation from 9831bd6 was already on main; this pass added scripts/verify-contract-fork-smoke.sh, manual QA §275, and crosslinks for INV-CONTRACTS-275-FORK-SMOKE.

What was verified locally

  • bash scripts/verify-contract-fork-smoke.sh (no FORK_URL) — 2/2 TimeArenaForkTest no-op pass (~3.8k gas)
  • FORK_URL=https://carrot.megaeth.com/rpc bash scripts/verify-contract-fork-smoke.sh — fork connectivity + head-state skip (no deployed proxy)
  • FOUNDRY_PROFILE=ci forge test --match-contract TimeArenaForkTest — pass with and without FORK_URL
  • Retired naming — no TimeCurveForkTest / TimeCurveFork.t.sol in contract-fork-smoke.yml, contracts/README.md, or contracts/.env.example (verify script asserts this)
  • Docs — contract-fork-smoke.md link target exists; bash scripts/check-doc-anchors.sh OK; manual QA §275 + invariant/skill crosslinks updated

Issue acceptance criteria

Criterion Status
forge test with FORK_URL unset — fork tests no-op Pass
Local FORK_URL + --match-contract TimeArenaForkTest Pass
contract-fork-smoke workflow dispatch with valid RPC Not verified here (GitHub Actions workflow; repo remote is GitLab — needs maintainer dispatch)
No TimeCurveFork* in workflow / contracts README / .env.example Pass
contract-fork-smoke.md link target Pass

Checklist for follow-up verification

  • Maintainer: dispatch .github/workflows/contract-fork-smoke.yml with valid RPC input or FORK_URL secret — confirm job runs --match-contract TimeArenaForkTest and succeeds
  • After mainnet Arena deploy (#259): TIME_ARENA_FORK_ADDRESS=<proxy> FORK_URL=<rpc> bash scripts/verify-contract-fork-smoke.sh — confirm test_fork_smoke_timeArenaHeadState reads live bytecode

Files touched (QA pass)

  • scripts/verify-contract-fork-smoke.sh (new)
  • docs/testing/manual-qa-checklists.md §275
  • docs/testing/contract-fork-smoke.md, invariants-and-business-logic.md
  • .cursor/skills/yieldomega-guardrails/SKILL.md, skills/README.md, skills/script-with-timearena-local/SKILL.md

Issue left open — contract-fork-smoke workflow dispatch was not exercised in this environment. Requesting verification by the other QA agent team for that remaining criterion before close.

Workflow dispatch acceptance criterion — verified

Dispatched contract-fork-smoke on GitHub (PlasticDigits/yieldomega) twice:

Run Commit Result Notes

Fix (b63d079)

Removed forge build --sizes from .github/workflows/contract-fork-smoke.yml. Fork smoke only needs RPC connectivity via TimeArenaForkTest; it does not deploy TimeArena. MegaETH deployment limits differ from vanilla EIP-170 on ubuntu-latest.
