The project is committed on `main` as commit 34f91f4, with no submodules.\n\n**What was built**\n\n- `src/EthUsdReader.sol`: constructor takes the aggregator address and maxAge, both immutable, with no external call. `latestPrice()` reads `latestRoundData`, reverts `StalePrice(updatedAt)` when the answer is older than maxAge, then `BadPrice(answer)` when the answer is zero or negative. No token, no owner, no storage. A `DECIMALS` constant of 8 documents the feed's precision.\n- `test/EthUsdReader.t.sol`: 24 unit and fuzz tests against a mock feed. They cover fresh, boundary and future timestamps, zero `updatedAt`, zero, negative and extreme answers, error precedence, feed reverts, a code-less target, and a storage-is-empty check.\n- `test/EthUsdReader.fork.t.sol`: 6 mainnet fork tests against the live Chainlink ETH/USD feed, pinned to block 26252743. They verify the feed's code, decimals and description, compare the reader's output to the feed verbatim and to the recorded value at that block, and exercise `StalePrice` via warp and `BadPrice` via mocking the live feed's answer.\n- `script/DeployEthUsdReader.s.sol` plus 3 tests calling its `deploy` function directly. Config is constants, not environment variables.\n- `lib/forge-std` v1.9.7 vendored as plain files. `README.md` documents parameters, assumptions and operational responsibilities.\n\n**Verification results**\n\n| Check | Result |\n|-------|--------|\n| forge build (solc 0.8.26) | clean, one informational block-timestamp lint |\n| forge fmt --check | pass |\n| forge test with verifier fuzz seed, network on | 33 passed, 0 failed |\n| forge test with unreachable RPC (scratch copy) | 27 passed, 6 fork tests skipped |\n\n**Two things to be aware of**\n\n- The fork tests use the public endpoint named in `foundry.toml` rather than an environment variable, since tests may not read the environment. On the offline verifier they skip cleanly instead of failing, as shown above.\n- The maxAge of 3 hours in the deploy script is my choice based on the feed's 1-hour heartbeat. It is documented as a deployer decision in the README and is easy to change before deploying.","treeHash":"9f8d3adfa1d5386b0418cfc460a3d96ec89dfb17","usage":{"cachedInputTokens":756561,"inputTokens":386,"model":"claude-fable-5-1","outputTokens":25300,"runtime":"claude","turns":28,"wallClockMs":326119}}],"verification":[{"checks":[{"durationMs":992,"exitCode":0,"name":"build","output":"Compiling 27 files with Solc 0.8.26\nSolc 0.8.26 finished in 909.25ms\nCompiler run successful!\n","passed":true},{"durationMs":1450,"exitCode":0,"name":"test","output":"No files changed, compilation skipped\n\nRan 3 tests for test/DeployEthUsdReader.t.sol:DeployEthUsdReaderTest\n[PASS] test_deployRejectsZeroAggregator() (gas: 62525)\n[PASS] test_deployRejectsZeroMaxAge() (gas: 68087)\n[PASS] test_deployUsesMainnetConstants() (gas: 223548)\nSuite result: ok. 3 passed;
