Nothing more depends on further tool calls.\n\n**Outcome.** The spend path is in good shape. All three suites pass offline (imd-flop 295 tests, spend-guard 66, viewer suite OK), and the seven findings of the earlier audit are closed at this commit. I found no path that mints or sends after a local refusal or after the deadline, no refresh that lowers a charge without a settlement under the project's own definition, and no secret or RPC URL reaching the ledger, a receipt, stdout or stderr. The five defects I did substantiate are low or informational, all in the math and cross-part agreement areas the assignment targeted. They are in `.imd-findings.json` with offline reproductions.\n\n**Findings**\n\n- **Viewer applies the daily cap to requester-paid rows** (`viewer/build-lane.py:106`, low). The row's `spent_before` is the job-budget accumulator for payer requester, but `daily_left` subtracts it from the seat's daily cap. A real six-run requester ledger that imd-flop correctly allowed renders row six as \"over the daily cap\" instead of \"over the reservation\", and a true job-budget breach is never shown.\n- **Daily cap compared against a rounded total** (`imd-flop/src/policy.ts:103`, low). Charges are booked unrounded, the sum is rounded to the nearest 1e-6, so two settlements of 0.4999996 plus a 1e-6 quote pass under a cap of 1 and the exact booked total becomes 1.0000002. Dust-sized, but the invariant breaks.\n- **run and refresh disagree on a redacted receipt** (`imd-flop/src/receipt-store.ts:84`, low). The run path treats a receipt that needed redaction as unproven and holds 0.186. A refresh on the identical read settles it to 0.05. The refactor left the redaction qualifier in only one caller of the shared settlement module.\n- **reserved_spend escapes the amount rule** (`imd-flop/src/receipts.ts:64`, low). Negative, NaN and Infinity reservations print as numbers on stdout, the file stores null for the non-finite ones, and spend-guard reports null plus \"invalid\" for the same receipt.\n- **Negative token counts inflate the pad** (`imd-flop/src/policy.ts:17`, info). Safe direction for imd-flop, refused by spend-guard, and not pinned by any quirk or vector.\n\n**Earlier audit, findings 1 to 7.** All closed and pinned: 1 and 2 by `knownSettledSpend` and `settlement.ts` with the run-settled-negative, run-estimated-with-settled-amount and run-settled-wrong-request-id vectors; 3 by the abort checks around the mint and the validated timeout flag; 4 and 5 by the withheld refusal text and the response-file fallback; 6 by the PaidGateError exit code; 7 by the URL parse and replacement in `postEthRpc`. The refactor changed no refusal decision I could find; the one booking divergence is finding three above.\n\n**What ran and what I only read.** Ran: `npm ci` and `npm test` in imd-flop, both Python suites, and my own Node and Python reproductions against the compiled `dist/` and the viewer harness, all offline, not as root, no keys. The earlier report was fetched read-only from the URL the task named. Read only: `gateway.ts`, `link.ts`, `keys.ts`, `secrets.ts` and the Solidity-oriented parts of the reference guides, which have no Solidity target here, so no Foundry proofs apply. observatory/ and tclk-rehearsal/ were left out as instructed.

Two consequences: (1) a row booked settled/0.05 is rewritten to released/0 (spend 0, cap_charge 0) by one later fresh read, freeing 0.05 of daily cap on the word of a receipt that contradicts the previous settlement; (2) in run, a receipt in state 'released' with settled_spend 0 books cap_charge 0 even when the completion's own usage.cost_flop said 0.15, and neither the ledger, `receipt`, nor the viewer surfaces the contradiction (the viewer's disagree check compares ledger spend to receipt settled, both 0, so the row renders as matching). 'released' is the gateway's state for a reservation that was let go without settlement; a completion that returned usage and cost is not that, so accepting released/0 as the final word for a completed call is a decision the code makes silently. Impact is bounded by the gateway being the payee (it can only under-charge the local cap), but the local ledger then under-reports spend relative to what the completion reported.","line":61,"path":"imd-flop/src/settlement.ts","reproduction":"Pure functions, offline: nextBooking({state:'settled', spend:0.05}, {fresh:true, identityOk:true, state:'released', settled:0}, 0.05) returns {state:'released', spend:0, cap_charge:0}; refreshBooking({state:'settled', spend:0.05, cap_charge:0.05}, same outcome) returns {kind:'append', booking:{state:'released', spend:0, cap_charge:0}}.

The findings file holds four substantiated findings, each with a verified path, line and snippet.\n\n**What I ran**\n- `npm ci` and `npm test` in imd-flop: 17 files, 295 tests pass. spend-guard: 66 pass. viewer: 59 pass. Run as user `imd2`, not root.\n- Offline reproductions against the built CLI and the viewer harness for every finding below. Nothing reached a faucet, key or paid endpoint.\n- Git diffs of the three refactor commits (policy.ts, settlement.ts, receipt-store.ts) against their parents.\n\n**What I only read**\n- gateway.ts network paths (chain id, genesis, child-key mint, RPC URL masking), the lock protocol in ledger.ts, secrets.ts scanning, spend-guard receipts.py, and all contract vectors.\n\n**Findings written to `.imd-findings.json`**\n- **Low, receipt-store.ts:84.** `receipt --refresh` books a settlement from a receipt the secret scan had to redact. `run` holds the reservation for the identical read. Reproduced: same body gives cap_charge 0.4 held via run, 0.01 booked via refresh.\n- **Low, settlement.ts:61.** A later `released` read with `settled_spend: 0` rewrites a booked `settled/0.05` to 0, and a `released/0` receipt wins over a completion that reported `cost_flop: 0.15` with no disagree flag anywhere.\n- **Low, build-lane.py:106.** The viewer applies the holder daily cap to requester-paid rows. Two admitted requester calls render an amber \"over the daily cap\" chip while `cap show` reports zero daily spend. No vector or test contains a requester row.\n- **Info, run.ts:212.** Earlier finding 6 is only partly closed. A child-key mint failure (nothing sent, charge 0) and a gateway HTTP error on the paid call (sent, hold kept) both exit 1.\n\n**Task items 1 to 5**\n- **Item 1.** No path mints or sends after a refusal or deadline. Every refusal precedes the `sent` row; `complete()` checks the abort signal before and after the gate and after the mint, and passes it into the mint and the completion.\n- **Item 2.** No release without a fresh, identity-matched, settling read, apart from the two low findings above. Failed reads, redacted receipts in `run`, wrong identity, and non-settling states all keep the hold.\n- **Item 3.** No leak found. The RPC URL is parsed before fetch and masked in transport errors. Bearer and child tokens are registered and scanned on every write. The stdout `withheld` string is itself re-scanned before storage.\n- **Item 4.** Vectors agree where comparable. The requester-row divergence above is the one cross-part disagreement not pinned by a vector or quirk.\n- **Item 5.** Findings 1, 2, 3, 4, 5 and 7 of the earlier audit are closed at this commit with tests. Finding 6 is partly closed as noted. The three refactor commits preserved every refusal and booking decision; the behaviour changes came in the later fix commits (TS-M1, KD-3, TS-M2), not in the splits.\n\n**Not covered**\n- observatory/ and tclk-rehearsal/ were out of scope and untouched. The claimUnassigned `rmSync` in keys.ts and the unescaped request id in spend-guard receipts.py were noted but not pursued, as they sit outside the spend path.","treeHash":null,"usage":{"cachedInputTokens":1937251,"cost":{"source":"runtime","usdMicros":6106789},"inputTokens":482,"model":"claude-fable-5-1","outputTokens":46086,"runtime":"claude","turns":35,"wallClockMs":815521}}],"verification":[]}
