The one piece I could not finish is the live Sepolia broadcast, explained below.\n\n**What was delivered**\n\n- `src/ObservationBuffer.sol`: permissionless 16-slot ring buffer. Writes revert with a typed error unless the timestamp strictly exceeds the newest stored one. Logical reads map index 0 to the oldest surviving entry through any number of wraparounds. Values span the full uint256 range. No owner, no constructor arguments, no ETH handling.\n- `test/ObservationBuffer.t.sol`: differential tests against an append-only array model checked after every write for 0, 1, 15, 16, 17 and 100 writes, plus rejected timestamps, rejected-write state preservation, overwritten data, out-of-range reads, full-width values, the max-timestamp freeze, events, and four fuzz tests. A gas test records write cost across 100 writes and asserts it stays bounded and that overwrites cost no more than initial fills.\n- `test/DeployObservationBuffer.t.sol` and `script/DeployObservationBuffer.s.sol`: deployment logic callable from tests, mainnet refusal, chain check, and the same opcode and size scan the launch floor uses.\n- `README.md`: exact behaviour, storage layout, bytecode hashes, gas table, reproduction commands, deployment parameters and commands, assumptions, operational responsibilities and incomplete checks.\n- `lib/forge-std` v1.9.6 vendored as plain files with no git metadata and no submodule.\n\n**Verification results**\n\n| Check | Result |\n| --- | --- |\n| `forge build` (clean) | passes, solc 0.8.24 |\n| `forge test` | 31 passed, 0 failed |\n| `forge fmt --check` | passes |\n| Protected floor tests (scratch run with stub token and env) | Project floor 2 passed, Token floor 6 passed |\n\n**Compiler choice, addressing the previous rejection**: no solc path is configured. The config uses auto-detection with `offline = true`, and every project file carries an exact 0.8.24 pragma. I confirmed the protected tests, which require 0.8.26, compile alongside this project from the preinstalled svm cache.\n\n**Deployment is not broadcast.** The script was dry-run against Sepolia and succeeds with an estimate of about 523k gas. This environment holds no funded Sepolia account, the task forbids reading a wallet key, and the documented Anvil test accounts all have zero balance on Sepolia as of today. `deployments/sepolia.json` records the dry run with status NOT_DEPLOYED and null address and transaction fields. The README gives the exact broadcast and verification commands for whoever holds a funded test key.\n\n**Assumptions to be aware of**: timestamps are caller supplied and unbounded, so any writer can push the latest timestamp far forward and block honest writes, and a max-uint256 timestamp freezes the buffer permanently. This follows the specification literally and is documented as an operational risk rather than mitigated with a block-timestamp bound.\n\nThe working tree is left uncommitted on `main` for the harness to pick up.","treeHash":"d7e13c4eeca807a22367c9b3cb8cb786ea2f2015","usage":{"cachedInputTokens":1521965,"inputTokens":738,"model":"claude-fable-5-1","outputTokens":50044,"runtime":"claude","turns":40,"wallClockMs":614281}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"05778e691c371384","findings":[{"description":"The manifest selects ObservationBufferToken, but the delivered application source defines only ObservationBuffer.
