Files Changed

• script/DeployBaseSepolia.s.sol — Foundry deploy script with curve generation
• script/MeasureGas.s.sol — Gas measurement script (createStoryline + chainPlot)
• docs/DEPLOYMENT-BASE-SEPOLIA.md — Deployment artifact doc
• broadcast/ — On-chain broadcast logs (TX receipts)

Validation Evidence

• All transactions confirmed on Base Sepolia (status: 0x1)
• Broadcast JSON logs with full receipts included in PR
• Build passes: forge build clean

Test plan

• forge build compiles without errors
• Deploy TX confirmed on-chain (block 38854535)
• createStoryline TX confirmed (4 event logs emitted)
• chainPlot TX confirmed (1 event log emitted)
• Verify contract on Basescan Sepolia (optional, can be done post-merge)

Verdict: REQUEST CHANGES

Summary

The deployment artifacts and scripts appear aligned with the Base Sepolia assignment, but the PR is not merge-ready because the required Foundry workflow is failing. The PR description also states the build passes, which is not true for the current head.

Findings

• [medium] Required CI is red because the new deployment script is not formatted to the repository standard.
  • File: script/DeployBaseSepolia.s.sol:27
  • Suggestion: Run forge fmt on the new script files and push the formatted result so forge fmt --check passes.

Decision

Requesting changes because the branch does not satisfy the build-pass requirement in the review checklist. Re-run the checks after formatting and then I can re-review quickly.

Verdict: APPROVE

Summary

The formatting fix cleared the failing Foundry workflow, and the PR now satisfies the review checklist for the Base Sepolia deployment and gas-capture deliverable.

Findings

• None.

Decision

Approving because the required checks are passing and the changes remain focused on deployment artifacts, measurement scripts, and documentation for the assigned testnet deploy task.

T2b Review: APPROVED

Code review findings:

1. Addresses verified — MCV2_Bond, WETH, and chain ID all match Base Sepolia values from the assignment (msg #457).
2. Curve math correct — J-curve with 500 steps, fixed-point arithmetic is sound. scarcity bottoms at 1e18 - (499 * 85e18 / 50000) = 0.1517e18, so no division-by-zero risk. Price floor (if == 0 then 1) is a reasonable guard.
3. Gas script — in-script gasleft() delta is an approximation, but the real gas is captured in the broadcast receipt JSON, which is the authoritative number. Fine for measurement purposes.
4. No secrets in diff — private key is loaded from env var, not hardcoded.
5. CI green after forge fmt fix.

No issues found.
