The findings file at the repository root holds seven substantiated findings, each with a file and line, a verified snippet, a concrete failing input, expected versus actual output, and a runnable vitest body that I executed against commit efd47f3 in a disposable copy of the package. No tracked file in the repository was changed.\n\n**Scope and method.** The subject is TypeScript, so the Foundry profile and the Solidity checklists do not apply directly; I used them as failure-mode lists (input validation, boundary, execution trace, accounting conservation) and reported nothing that depends on Solidity semantics. I read all of run.ts, receipts.ts, ledger.ts, providers.ts, store.ts, secrets.ts, cli.ts, gateway.ts, match.ts and the full test suite. The existing suite passes (80 tests). The Python spend guard and the live gateway were not exercised.\n\n**Findings, by severity**\n\n- **High, run.ts:57.** A non-numeric token count in the gateway estimate (for example `\"abc\"` or `{}`) makes the padded quote NaN. NaN fails every `>` comparison, so the per-call cap, the daily cap and the requester job budget are all bypassed, the provider is called with `max_cost_flop` serialised as null, and the ledger stores `cap_charge: null`. Observed: a 0.5 FLOP raw quote under a 0.1 cap was sent three times and the day total stayed 0. A valid reported cost cannot repair it because `Math.max(NaN, x)` is NaN.\n- **Medium, ledger.ts:58.** The daily and job sums add `cap_charge` without a finiteness check. A null row counts as 0, a missing field turns the whole sum into NaN, and in both cases the next run passes the daily cap comparison.\n- **Medium, run.ts:233.** A completion with no `usage` object throws a TypeError after the paid call and after the response and receipt files are written. The post-call ledger line is never appended, so the attempt stays at `sent` and a known settlement (including an explicit 0) is never recorded.\n- **Medium, run.ts:225.** The withheld-text fallback write re-includes the unscanned gateway `usage` object. A secret-shaped field in it makes both writes throw, the paid completion text is lost, no receipt is written and the ledger stays at `sent`.\n- **Low, run.ts:231.** A 64-hex string in the receipt's `error` or `settled_spend_raw` aborts the receipt write before the ledger line, so a gateway-settled 0 is lost and the full reservation stays charged.\n- **Low, cli.ts:322.** `--timeout-ms` is not validated. NaN or any value above 2147483647 is clamped by Node to 1 ms, so the run aborts at once and is booked as `timeout_unknown` with the full reservation.\n- **Low, run.ts:59.** A positive quote below 5e-7 FLOP rounds to a padded value of 0, so the call is sent with a zero reservation that stays zero while spend is unresolved.\n\n**Confirmed correct.** I found no path by which withheld completion text reaches stdout, the response file, the receipt or the ledger. The scan error message carries only field paths and reasons. Known settlements including zero, negative and non-finite settlements, lower and higher reported usage, and omitted cost all behave as the specification requires, which the existing ledger-reservation tests also cover.\n\n**Unverified lead, not in the file.** Two concurrent CLI processes can both read the ledger before either appends its `sent` line, since there is no lock around check-and-append. I could not reproduce it in-process because that section is synchronous within one process, so it is reported here only.","treeHash":null,"usage":{"cachedInputTokens":1059154,"cost":{"source":"runtime","usdMicros":5178311},"inputTokens":322,"model":"claude-fable-5-1","outputTokens":47255,"runtime":"claude","turns":29,"wallClockMs":663738}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"74cf0246a1dda0ce","findings":[{"citation":"resolved","description":"padQuote validates estimated_cost_flop but not estimated_input_tokens / estimated_output_tokens. With a non-numeric token field (JSON string, object, boolean) `tin + tout` becomes a string, `<= 0` is false, `raw / (tin + tout)` is NaN and the function returns `{ raw, padded: NaN }` instead of null. In runJob the per-call check `q.padded > cap.perCall` (line 176), the daily check `q.padded > left` (line 180) and the requester budget check (line 183) are all false for NaN, so the call is sent. The `sent` ledger line is written with `cap_charge: NaN`, which JSON.stringify turns into `null`; `maxCostFlop: NaN` is passed to the provider, so for the flop provider the child-key mint body becomes `max_spend: null` and the chat request `max_cost_flop: null`, removing the server-side cap as well. After the call, `unresolvedCharge = Math.max(NaN, costReported)` is NaN, so the final line is also `cap_charge: null`. spentToday adds `null` as 0, so spent_before stays 0 and the daily cap is never consumed. Impact: one malformed estimate response from the gateway (the counterparty the local cap is meant to bound) disables the per-call cap, the daily cap, the requester budget and the server max_spend for that call and leaves no exposure on the books; repeated calls stay at 0 spent.

The findings file at `.imd-findings.json` holds six substantiated defects, each with a file and line, the exact failing input, expected versus actual, and a runnable vitest reproduction that I confirmed fails on commit efd47f3. The project's own suite passes on this commit (80 tests), so none of these paths are covered today. No tracked files were changed; only `.imd-findings.json` and `test/scratch/` were added.\n\n**Findings, by severity**\n\n- **High, run.ts:57.** `padQuote` never validates the token counts. A non-numeric `estimated_input_tokens` yields `padded: NaN`, every cap comparison is false for NaN, the call is sent with `max_spend: null`, and the ledger stores `cap_charge: null`. Three calls under a 0.2 cap all went through and status reported 0 spent.\n- **High, receipts.ts:61.** A numeric `settled_spend` is booked as the settlement regardless of `state`. A receipt saying `reserved` with `settled_spend: 0` erased the 0.18 reservation and five calls under a 0.2 cap all succeeded.\n- **Medium, run.ts:238.** The receipt's identity is not checked before booking spend. A receipt with a foreign request id and correlation id still zeroed the charge, even though the printed match said mismatch.\n- **Medium, ledger.ts:58.** The daily and job sums add `cap_charge` unvalidated. A line with the field missing makes the total NaN and all later cap checks pass; a null line counts as 0.\n- **Low, run.ts:225.** The withheld fallback re-writes the same blocked record. A scan hit in `usage` throws again, losing the paid response, writing no receipt and leaving the attempt at `sent`. Nothing leaked to stdout.\n- **Low, cli.ts:322.** `--timeout-ms` is unvalidated. NaN, 0 and values above 2^31-1 become a 1 ms timer, aborting the sent call and charging the reservation as unknown spend.\n\n**Checked and found sound.** Lower reported usage never lowers the unresolved charge, higher valid usage raises it, explicit settled zero charges zero, and negative, nonfinite, string and object settlements stay unknown. The withheld text path does not leak into stdout, the response file, the ledger or error messages. An in-process concurrency race did not reproduce because the check-then-append segment is synchronous, so it was not reported.\n\n**Scope note.** This is TypeScript, so the Foundry proof mechanism does not apply; reproductions are embedded in each finding's `reproduction` field instead.

If a pending row carries a provisional settled_spend of 0 (or any value below the quote), the ledger's latest line for the attempt gets spend=<that number>, cap_charge=<that number>, and the 0.18 FLOP reservation that was booked by the `sent` line disappears from spentToday()/jobSpent() while the gateway still holds the reservation. The design rule in ledger.ts:34 ('while spend is unknown, the padded quote, raised if reported cost is higher') is violated: unknown spend no longer retains the reservation and a lower provisional figure reduces unresolved exposure. Repeated calls then pass the daily (or job) cap indefinitely, since every attempt contributes 0 to the day total.

A `{state:\"estimated\", settled_spend:0.01}` receipt cut unresolved exposure from the 0.18 reservation to 0.01 despite a reported cost of 0.25. The existing tests never test a state/amount disagreement.\n- **Medium. Receipt identity unchecked** (`imd-flop/src/receipts.ts:55`). A receipt whose `request_id` differs from the attempt's is saved under our id, its settlement is applied to our ledger, and match reports `matches`. The gateway documents that the body's id can be an X-Request-ID rather than our Idempotency-Key.\n- **Low. Missing usage crashes after the paid call** (`imd-flop/src/run.ts:233`). A completion without `usage`, or with array content, throws after the response and receipt are written. The reservation is retained, but the run exits 1 with a raw TypeError and prints nothing.\n- **Low. Refresh never updates the ledger** (`imd-flop/src/cli.ts:404`). A settlement that rises from 0.05 to 0.15 on refresh leaves cap_charge and the day total at 0.05.\n- **Low. Timeout flag unvalidated** (`imd-flop/src/cli.ts:322`). `--timeout-ms abc` or `0` aborts after 1 ms, mints a child key on the live path, and books a permanent unknown-spend reservation.\n\n**Checked and clean.** No path was found by which withheld completion text reaches stdout, stderr, the ledger, receipts, response files or temp files. Omitted, negative, NaN, infinite, string and object settlement amounts all keep the reservation. Zero and positive settlements in `settled` state charge correctly. Lower reported `cost_flop` never lowers unresolved exposure and higher finite values raise it.\n\n**Not reproduced.** A cross-process read-then-append race on `ledger.jsonl` between two concurrent runs could pass the cap twice. I could not build a deterministic reproduction within the budget, so it is not in the file.","treeHash":null,"usage":{"cachedInputTokens":1513443,"cost":{"source":"runtime","usdMicros":5081003},"inputTokens":418,"model":"claude-fable-5-1","outputTokens":36998,"runtime":"claude","turns":39,"wallClockMs":867574}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"e3a598aae0640402","findings":[{"citation":"resolved","description":"padQuote validates estimated_cost_flop but not estimated_input_tokens / estimated_output_tokens, which FlopProvider.estimate passes through from the gateway JSON unchecked (gateway.ts:40 `(await res.json()) as Estimate`).

Findings are in `.imd-findings.json` at the repository root, with 11 merged findings, every one reproduced against commit efd47f3.\n\n**How I checked.** The project is TypeScript, so Foundry proofs do not apply and none are attached. I copied imd-flop to a temp directory outside the tree, ran `npm ci`, confirmed the existing suite passes, then wrote one vitest file that drives each specialist claim through the same provider hook the project's own tests use. All 16 reproduction cases matched the specialists' observed behavior. Control runs confirmed valid known settlements still work: settled 0 charges 0, settled 0.05 charges 0.05, lower unresolved usage keeps the 0.18 reservation, higher usage raises it to 0.25, and a negative settled amount keeps the reservation. No repository file was modified.\n\n**Kept, after merging duplicates across the four specialist areas:**\n\n- **High, run.ts:57.** A non-numeric token count in the gateway estimate makes the padded quote NaN. Every cap check passes, the gateway gets max_cost_flop null, and the attempt is booked at cap_charge null, which the day total counts as 0. Three specialists reported this; merged into one.\n- **High, run.ts:238.** Receipt state is ignored. A receipt in state reserved or estimated with settled_spend 0 erases the reservation, and settled_spend 0.01 beats a reported cost of 0.25. Five calls under a 0.2 cap all succeed.\n- **Medium, receipts.ts:55.** The receipt's request_id is never compared to the attempt. A foreign receipt with settled 0 zeroes the charge, is saved under our id, and prints as matches.\n- **Medium, ledger.ts:58.** The spend sum is unvalidated. A missing cap_charge makes the total NaN and the daily cap fails open; a null counts as 0.\n- **Medium, secrets.ts:52.** The 64-hex rule misses a 128-hex run, so a key-shaped value is saved and printed by `run --json`. This is the one leak path found for withheld text. Raised from the specialist's low because the value reaches stdout.\n- **Low, six items.** Missing usage object crashes after the paid call; the withheld fallback re-writes the unscanned usage object; a receipt string tripping the scan blocks the settled-0 ledger line; tiny quotes round to a 0 reservation; `--timeout-ms` is unvalidated and collapses to 1 ms; `receipt --refresh` never updates the ledger.\n\n**Dropped or demoted.** Nothing failed to reproduce. The specialists' proofs were vitest, not Foundry, so I verified them by running equivalent cases rather than attaching them as proofs. The two cli.ts findings fall outside the three focus files but sit on the run path, so they are kept at low.","treeHash":null,"usage":{"cachedInputTokens":1434714,"cost":{"source":"runtime","usdMicros":4723191},"inputTokens":390,"model":"claude-fable-5-1","outputTokens":37494,"runtime":"claude","turns":29,"wallClockMs":532880}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"dedd4428da8fa41e","findings":[{"citation":"resolved","description":"padQuote checks only estimated_cost_flop. estimated_input_tokens/estimated_output_tokens come from the gateway's /models/estimate JSON (gateway.ts:40, no validation).

Every path, line and snippet in it matches the tree. I reproduced each one with a vitest script, using the mock provider and no network, in a copy of `imd-flop` under `$TMPDIR` with its own `npm ci`. Nothing in the repository changed except the findings file. The project's own suite passes as it stands (80 passed, 1 skipped). This is TypeScript, so the Solidity-specific steps don't apply: there are no Foundry proofs, and the reproductions are given as vitest steps instead.\n\n**Findings**\n\n1. **High: a nonnumeric token count in the estimate turns the reservation into NaN** (`src/run.ts:57`, `padQuote`). The check only validates `estimated_cost_flop`. An input like `estimated_input_tokens: \"n/a\"` makes `tin + tout <= 0` evaluate false, so the padded quote becomes NaN.\n   - Every cap check is a `>` comparison, which is always false against NaN, so the per-call cap, daily cap and requester budget are all skipped.\n   - The call goes out with `maxCostFlop` NaN, which the child-key mint sends as `max_spend: null`, so there is no server-side cap either.\n   - Even a valid reported cost is lost, because `Math.max(NaN, 0.18)` is NaN.\n   - The ledger stores `cap_charge` as null, and `spentToday` adds null as 0.\n   - With a 0.2 FLOP daily cap and a quote of 50 FLOP, three calls all went out and today's spend stayed at 0.\n2. **Medium: `settled_spend: 0` counts as a real zero settlement even when the receipt isn't settled** (`src/run.ts:238`). A receipt still in state `\"reserved\"` with `settled_spend: 0` set the charge to 0 instead of the 0.18 reservation.\n3. **Medium: the receipt's `request_id` is never checked against the call** (`src/receipts.ts:55`). A receipt for a different request with settled 0 became this call's charge (0), and the match check still said \"matches\".\n4. **Low: a completion with no `usage` object crashes the run** (`src/run.ts:233`). The crash happens after the paid call, with exit code 1 and \"Cannot read properties of undefined\". The receipt said settled 0.1, but the ledger was left at `sent` with 0.18. The reservation is kept, but the known settlement is never recorded.\n5. **Low: rounding can shrink the reservation** (`src/run.ts:59`). The padded quote is rounded to the nearest 1e-6, so a raw quote of 4e-7 reserves 0 and a raw quote of 1.4e-6 reserves only 1e-6, less than the quote itself.\n6. **Low: withheld text can leak through a gap in the secret scan** (`src/secrets.ts:52`). It only matches hex runs of exactly 64 characters, so a 128-hex key (a common format for Ed25519 secret keys) passes. The text is then saved to the response file and printed by `run --json`. This file is outside the three focus files, but it is the only check deciding what gets withheld.\n\n**What held up**\n- **Withholding:** when the scan does catch the text, it is withheld correctly. `text` is null in both stdout and the file, the reason never contains the secret, and plain output never prints completion text.\n- **Settlement amounts:** missing, negative, nonfinite and string `settled_spend` all keep the reservation.\n- **Reported cost:** a lower reported cost doesn't reduce the charge, and a higher one raises it.\n- **Other paths:** timeouts and HTTP errors keep the charge, and refusals before the child key is minted charge 0, which is correct.\n- **Valid settlements:** a real settled amount, including 0 on a receipt in state \"settled\", still becomes the charge.\n\n**Not covered:** I didn't test concurrent runs from separate processes, which might both pass the cap check before either writes to the ledger. The Python spend guard was out of scope.","treeHash":null,"usage":{"cachedInputTokens":586930,"cost":{"source":"runtime","usdMicros":972060},"inputTokens":21,"model":"claude-opus-5-5","outputTokens":18030,"runtime":"claude","turns":12,"wallClockMs":208001}}],"verification":[]}
