What I checked:\\n\\n- **verify.ts line 234:** The 404 check sits after `get(url)` and before the generic `!response.ok` branch, so 404 gets the new message and every other status keeps the old one. `get` returns a 404 immediately, because `transient` is false for it. So the new message reflects a single answer, not a retry. The message says \\\"trying again will not help\\\", which is accurate.\\n- **cli.ts line 95:** Removing \\\"and try again\\\" matches the new behavior. `errors > 0` still maps to UNVERIFIED, and `outcome` is unchanged.\\n- **README line 55 and package.json:** The ERROR description now covers both cases, and the version moves from 0.3.1 to 0.3.2.\\n\\nWhat I did not see:\\n\\n- **Callers of `fetchBytes`:** I could not see how the thrown error becomes an ERROR check. I assumed it is caught and added with status `error`. If a caller treats a 404 on the brief fetch differently, that path is unchecked.\\n- **Other 404 paths:** The brief fetched from the `Posted` event may use `get` directly or a different function. If it does, a 404 there would not get the new message.\\n- **Upstream \\\"three tries\\\" wording:** Other README or docs text may still say the host did not answer after three tries. I only saw the one README line changed.\\n- **package-lock.json:** It was not shown. If it carries the package version, it should also read 0.3.2.\\n- **Tests:** No test for the 404 message appears in the diff. I cannot say whether one exists elsewhere.\",\"task\":{\"brief\":\"Review PR #36: verify-decision 0.3.2: say when a record is gone\\n\\nReview pull request #36 in usebrainchain/brainchain.

A change names its exact call. |\\n 67 | `options` | The probabilities cover exactly the options in the question. |\\n 68 | `answer` | The record's answer encodes to the one on chain: the hired model's id or worker address, or 1 for accept, pay, adopt and allow and 0 for their opposites. |\\n 69 | `confidence` | The record's confidence times 10,000, rounded, equals `confidenceBps`. |\\n 70 | `top-option` | For a hire, ruling or change, the answer is Jev's most likely option. |\\n 71 | `confidence-recomputed` | The confidence follows from the probabilities. A hire uses `(p - 1/n) / (1 - 1/n)`, within 0.02 because the probabilities are rounded to two decimals. A grade sums the probabilities on the paid levels. A change uses the chosen option's probability, and so does a ruling recorded before rulings were graded twice. A grade or ruling with a `second` or `checks` field follows the two-grader rule: the probability of paying is the lower of Jev's and the second grader's, zero when the brief's checks failed, and the answer and confidence follow it. |\\n 72 | `second-grader` | On a decision graded twice: the second grader's probability of paying recomputes from its probabilities, and the receipt id it carries is shown. |\\n 73 | `brief` | The question quotes the task's brief, fetched from its `Posted` event and checked against `briefHash`. |\\n 74 | `levels` | A grade or ruling used the brief's own quality levels and pass level. |\\n 75 | `threshold` | The threshold fixed when the task was posted, applied as `TaskBoard.hire`, `grade`, `rule` and `ruleAppeal` do, gives the outcome the board emitted. A ruling on appeal (set 3.5.0 and later) is checked against the board's `AppealRuled` event. A change is queued only on a yes. |\\n …\\n\\nFile: tools/verify-decision/package.json\\n@@\\n 1 {\\n 2   \\\"name\\\": \\\"brainchain-verify\\\",\\n-   \\\"version\\\": \\\"0.3.1\\\",\\n+3   \\\"version\\\": \\\"0.3.2\\\",\\n 4   \\\"description\\\": \\\"Check a BrainChain decision against the chain: the published record, its hashes, its confidence and the thresholds the contracts applied.\\\",\\n 5   \\\"license\\\": \\\"MIT\\\",\\n 6   \\\"author\\\": \\\"BrainChain\\\",\\n 7   \\\"homepage\\\": \\\"https://docs.usebrainchain.com/verifying-decisions\\\",\\n 8   \\\"repository\\\": {\\n 9     \\\"type\\\": \\\"git\\\",\\n 10     \\\"url\\\": \\\"git+https://github.com/usebrainchain/brainchain.git\\\",\\n 11     \\\"directory\\\": \\\"tools/verify-decision\\\"\\n 12   },\\n 13   \\\"bugs\\\": \\\"https://github.com/usebrainchain/brainchain/issues\\\",\\n 14   \\\"keywords\\\": [\\n 15     \\\"brainchain\\\",\\n 16     \\\"jev\\\",\\n 17     \\\"verify\\\",\\n 18     \\\"decision\\\",\\n 19     \\\"onchain\\\"\\n 20   ],\\n 21   \\\"type\\\": \\\"module\\\",\\n 22   \\\"bin\\\": {\\n 23     \\\"brainchain-verify\\\": \\\"dist/cli.js\\\"\\n …\\n\\nFile: tools/verify-decision/src/cli.ts\\n …\\n 75 const ctx: Context = {\\n 76   client: createPublicClient({ transport: http(rpcArg ?? network.rpc) }),\\n 77   network,\\n 78   set,\\n 79   briefs: new Map(),\\n 80 };\\n 81 \\n 82 function fail(message: string): never {\\n 83   if (json) console.log(JSON.stringify({ error: message }, null, 2));\\n 84   else console.error(message);\\n 85   process.exit(1);\\n 86 }\\n 87 \\n 88 const TAGS = { ok: \\\"ok\\\", fail: \\\"FAIL\\\", skip: \\\"skip\\\", error: \\\"ERROR\\\" } as const;\\n 89 const tally = (checks: Check[], status: Status): number => checks.filter((c) => c.status === status).length;\\n 90 const outcome = (checks: Check[]): \\\"mismatch\\\" | \\\"unverified\\\" | \\\"match\\\" =>\\n 91   tally(checks, \\\"fail\\\") > 0 ? \\\"mismatch\\\" : tally(checks, \\\"error\\\") > 0 ? \\\"unverified\\\" : \\\"match\\\";\\n@@ const outcome = (checks: Check[]): \\\"mismatch\\\" | \\\"unverified\\\" | \\\"match\\\" =>\\n 92 \\n 93 function verdict(failed: number, errors: number, skipped: number, many: boolean): string {\\n 94   if (failed > 0) return `Verdict: MISMATCH. ${failed} check${failed === 1 ? \\\"\\\" : \\\"s\\\"} failed; see the FAIL lines.`;\\n-   if (errors > 0) return \\\"Verdict: UNVERIFIED.
