Implemented agent 2 as a round botanist with a potted plant, updated labels/count, corrected the antenna, and added exact SVG snapshot checks and documentation.

All budgets pass:

• Room/desks: 1,135 / 2,000 bytes
• Agent 2 + object: 1,044 / 1,500 bytes
• Runtime: 7,825 / 10,000 bytes

forge build, 38 Solidity tests, 4 SVG tests, and forge fmt --check pass. LaunchToken, launch.json, and protected configuration remain unchanged.

Sepolia deployment remains pending: no configured signer/service or RPC endpoint was supplied. Local deployment simulation passed; no transaction was broadcast.

Updated only launch.json to describe the accepted part 2 implementation, preserving deployment settings.

Validated the supplied schema, token metadata, and constructor ABIs. forge build succeeded; all 38 Foundry tests and 4 SVG checks passed.

Sepolia deployment remains pending through the launch pipeline.

The audit is complete. Findings are written to .imd-findings.json and no source, test or config file was touched.

Verdict: no blocking defects. The implementation does what part 2 asks, and the tests assert what the brief requires. I found one stale-documentation issue and two informational notes.

What I verified independently

• forge build --offline, forge test --offline (38 passed), forge fmt --check, the offline deploy dry run and the four Python tests all pass.
• The committed room.svg is 3,481 bytes with no trailing newline, and its SHA-256 equals the constant pinned in test_renderMatchesPinnedRoomSvg.
• Sizes measured from artifacts and the SVG match every figure in README, STYLE.md and launch.json: room 1,135, agent 1 1,296, agent 2 1,044 (character 696, seedling 310, wrapper 38), Room runtime 7,825 bytes, LaunchToken 1,323.
• Git diff against the part 1 commit shows Agent1.sol changed on exactly one line (antenna cy from -58 to -57.5). RoomLayout.sol and LaunchToken.sol are unchanged. A programmatic bounds scan of both placed agents gives agent 1 y -60..43 and agent 2 x -34..46, y -54..43, both inside the STYLE.md box and equal to the bounds STYLE.md claims.
• Agent 2 uses only palette colours, has one animation, no monitor or keyboard, a round head and oval torso, faces right, and its pot sits on the desk edge without covering the desk top or nameplate.
• Room has no storage, payable path, external call or forbidden opcode. ABI exports match the compiled ABI. The manifest is schema-valid with identifiers and constructor args identical to part 1.

Findings, ranked

1. Low, README.md:168 and REVIEW.md:14. Both assert launch.json is byte-for-byte unchanged, but the manifest commit rewrote the notes field for part 2. Deployment fields are identical, so only the prose is wrong.
2. Info, test/Room.t.sol:33. The Foundry suite pins render() to a hash but cannot read room.svg because fs_permissions is empty. Appending a newline to room.svg leaves forge test green; only the Python companion test catches it. No in-forge fix exists without a config change.
3. Info, README.md:159. Sepolia deployment is reported as pending with no address. This is consistent with the network's rule that contributors do not broadcast.
