They are in `.imd-findings.json`, and each quoted line matches the source. I changed nothing in the repository and ran all probes against a copy in `/tmp`.\n\n**The partial I11 is now fixed.** `guard.py:94` refuses a negative max-tokens, max-tokens above 10,000,000, and any cap that is missing, NaN, infinite or below 1e-6, all before the estimate call. Those cases record `refused_local`, exit 3, write the ledger row, and make no request. The exact limits, 10,000,000 tokens and a cap of 1e-6, still request one estimate and can still pass. I found no other input that is sure to be refused but still triggers a request, and the cap-of-1e-6 lower limit is reachable. The full spend-guard suite (57 tests) passes. I didn't have the full report for job d7e11822, so the only finding I could check by ID was this I11. The earlier fixes the commit messages mention (M1, L2–L10, I12) are covered by the passing tests.\n\n**New findings:**\n1. **Medium – the receipt key leaks on a redirect (`receipts.py:11`).** The script follows redirects, and Python's urllib copies the `Authorization` header to the new address, even on a different host or plain http. I tested it with a local server that redirects to a second host: the second host received `Bearer sk-SECRET-123`. This is the broad sign-up key. The fix is to refuse redirects on requests that carry the key, or at least strip the header when the host or scheme changes.\n2. **Low – a NaN or Infinity in a receipt crashes the tracker (`receipts.py:57`).** The JSON parser accepts NaN in fields that are passed straight through, such as `terminal_event`. The output step rejects it, so the script stops with a traceback, exit 1 and no output. Every later receipt in the list is lost, including a `released` one a person may need before resending. A bad or missing `--last-known` file fails the same way. The script's own description promises one JSON row and exit 0 for every outcome.\n3. **Info – `--max-tokens` takes input that `--cap` rejects (`guard.py:85`).** `1_6`, `' 16 '` and Arabic-Indic `١٦` are all read as 16 and can end in `would_send`. `--cap` rejects the same typos with exit 2.\n\nSome rounding cases I left out as immaterial. In about 0.07% of random quotes, `ceil6` lands below the unpadded figure, by at most 1e-12. A would_send row still never shows a padded quote above its cap. Reading `--cap` as a float also loses precision only below a millionth of a FLOP.\n\nEverything was checked offline with local servers and the project's stubbed-network test harness. The project is Python, so there are no Foundry proofs. I covered the Execution Trace, Periphery and First Principles passes for this folder and looked at nothing outside it.","treeHash":null,"usage":{"cachedInputTokens":351990,"cost":{"source":"runtime","usdMicros":645732},"inputTokens":21,"model":"claude-opus-5-5","outputTokens":14033,"runtime":"claude","turns":11,"wallClockMs":160028}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"1a7ecd03bd365366","findings":[{"citation":"resolved","description":"ceil6 (guard.py:43-49) scales by 1e6, accepts the nearest integer when |scaled - nearest| <= 1e-6, and main then requires candidate >= unrounded - 1e-12.

The findings file is written and every snippet was verified against the tree. No repository files were changed.\n\n**Follow-up on audit d7e11822 (v8 item 5, Py-I11 partial): fixed.** The guard at `spend-guard/guard.py:94` now refuses `--max-tokens` above 10,000,000 and any cap below 1e-6 before the estimate request. I confirmed with stubbed runs that 10,000,001 and caps of 9.9e-7, 5e-7 and 5e-324 give refused_local, exit 3, null quotes and zero estimate calls, while the boundaries 10,000,000 and 1e-6 still request exactly one estimate. The earlier 355a3703 items (M1, L2 to L10, I11, I12) remain fixed; all four existing suites pass at this commit. I found no remaining locally decidable input that still reaches the estimate endpoint.\n\n**New findings written to `.imd-findings.json` (7 total, none above low):**\n\n- **Low, guard.py:124.** The six-decimal rounding helper uses absolute tolerances, so a well-formed quote in the thousands of FLOP that sits one float ulp above a 1e-6 grid point is rounded down, fails the 1e-12 check, and is refused as if malformed with quote_padded null. Input: cost 2050.745279, 3 input and 8 output tokens, cap 30000 refuses. The neighbours 2050.745278 and 2050.745280 send. Roughly 0.07 to 0.1 percent of quotes at or above 10,000 FLOP hit this.\n- **Low, guard.py:85.** The max-tokens argument uses bare `int()`, which accepts underscores, Arabic-Indic and fullwidth digits, whitespace and a plus sign. The cap parser rejects exactly those as typos, so `--max-tokens 1_0` sends an estimate while `--cap 1_0` exits 2.\n- **Low, receipts.py:23.** An empty or whitespace-only key file becomes an empty key and a request goes out with the header `Bearer ` and nothing after it, instead of the nothing-sent exit the JSON branch gives.\n- **Low, receipts.py:48.** On a non-200 response a missing last-known file raises a traceback and exit 1, losing the structured error row the tool promises.\n- **Info, guard.py:140.** A cap with more than six decimals, such as 0.0500001, is compared against the six-decimal ceiling of the quote, so an in-cap quote is refused. Conservative but undocumented.\n- **Info, guard.py:61.** The amount check lets -0.0 through, so a receipt row can print a minus-signed spend.\n- **Info, receipts.py:55.** An empty receipt list prints no row at all.\n\n**Scope and limits.** Only the spend-guard folder was reviewed, offline, with the gateway stubbed through the project's own test harness. The math guides (Precision, Boundary, Numerical Gap) were applied to every arithmetic path in guard.py; the receipts items came from the same pass over its amount handling and exit contract.

I've assumed it is the \"v8\" list in the commit messages. Only item 5 (Sonar Py-I11 partial) touches `spend-guard/`, and it is fixed:\n- **Over 10,000,000 max-tokens:** refused before the estimate is requested (`guard.py:94`).\n- **Caps below 1e-6:** also refused before the request, including nan, inf, `1e400` and `5e-324`.\n- **Boundaries:** exactly 10,000,000 and exactly 1e-6 still make one estimate request.\n- **The refusal row:** exit 3, null quotes, still written to the ledger.\n\nIf d7e11822 had other `spend-guard` findings outside the v8 list, I couldn't check them.\n\n**Findings:**\n1. **Low, `receipts.py:57`:** the receipt reader accepts the non-standard values `NaN` and `Infinity` from the gateway but refuses to print them. One receipt such as `{\"state\":NaN}` makes it crash with exit 1, and every receipt after it, including settled spend, is never reported. Its own docstring promises one row per outcome and exit 0. A `--last-known` file containing NaN crashes it the same way. I reproduced this.\n2. **Low, `guard.py:120`:** the cost padding is a fixed 20 tokens, measured once for one Qwen prompt that had a system message. It is applied to any `--model` and to the default empty `--system`. With no system message, Qwen's template adds a default one of about 15 tokens, so a quote just under the cap can pass while the real cost is over it. This rests on Qwen's published chat template, not a live measurement, since the review was offline.\n3. **Info, `guard.py:47`:** very small quotes are handled inconsistently. With a cap of 1, a quote of 1e-13 is refused but a quote of 3e-12 passes with a padded value of 1e-06. It wastes nothing, but contradicts the code comment that the padded quote is always at least 1e-6.

The findings file holds 12 merged, reproduced findings, all at the low or info level, and no repository file was changed.\n\n**Prior audit status.** The I11 partial from the earlier job is fixed at this commit. The early refusal on guard.py line 94 now covers max-tokens above 10,000,000 and caps below 1e-6, and the v8 regression plus all 57 existing spend-guard tests pass offline. The 355a3703 items (M1, L2 to L10, I11, I12) are all still covered by passing suites.\n\n**What the specialists reported.** All 18 specialist findings reproduced against the code. I merged them into 12, since three groups were the same mechanism reported by two or three areas:\n\n- NaN or Infinity in a receipt's request_id, state or terminal_event crashes receipts.py and drops every later receipt (three reports merged, kept as low rather than medium: fail-closed and the crash is visible).\n- The last-known file crashing the error row (two reports merged).\n- The lenient --max-tokens parser accepting typos that --cap refuses (three reports merged).\n- The empty receipt list printing nothing (two reports merged).\n\n**Severity changes.** I lowered the redirect finding from medium to low. Whoever controls the original gateway response already holds the key from that request, so the real added exposure is a misconfigured gateway handing the key to a third-party host or an http downgrade. The reproduction with two local servers does confirm the key is forwarded cross-host. The template-pad finding stays as info and is labelled a trust assumption, because the billed token count cannot be checked offline.\n\n**Own passes.** Extra probes found nothing new that is not already fail-closed: a 200 with an empty body, a 401 body with NaN, a JSON-string key file and a 5000-digit max-tokens all refuse or report cleanly.

I found five other defects in spend-guard and wrote them to `.imd-findings.json`: one medium and four low. Each names a failing input, and I reproduced all five offline with stubbed `urlopen`, using the repo's own test harnesses. No repository files changed, and the probe scripts stay in `/tmp`.\n\n**I11 follow-up: fixed.** `guard.py:94` refuses before the estimate call when `--max-tokens` is above 10,000,000 or the cap is below 1e-6.\n- Both rules are sound. A quote's output count must be at least max-tokens and at most 10M. The rounded-up padded quote can never be below 1e-6, because a smaller value rounds to 0 and is refused at line 124.\n- `test_audit_v8.py` covers 10,000,001, 10^12, 5e-7, 9.99e-7 and 5e-324, and checks that nothing is requested. At the exact limits (10,000,000 and 1e-6) one estimate is still requested and the row is `would_send`.\n- The decision line (140) doesn't repeat these limits, but that is harmless: an early refusal leaves no quote, so it can't pass.\n- All 57 spend-guard tests pass.\n\n**About d7e11822:** I couldn't find that audit's report anywhere in the tree. So I checked it against what the history records: commit `1210fc5` (v8 item 5, the I11 partial) and the earlier 355a3703 fixes (I11, I12, L10), which the existing tests cover. Any other d7e11822 finding I couldn't verify.\n\n**New findings:**\n1. **Medium, `guard.py:69`.** A gateway receipt with `NaN` or `Infinity` in `state`, `request_id` or `terminal_event` crashes `receipts.py` with exit 1. It prints nothing, so later receipts and their spend are hidden too. Example body: `[{\"request_id\":\"r1\",\"state\":NaN},{\"request_id\":\"r2\",\"state\":\"settled\",\"settled_spend\":0.1}]`. The earlier L10 fix only cleaned the two spend fields.\n2. **Low, `receipts.py:41`.** `--request-id` goes into the URL unencoded, so `../../models` or `r1?all=1` changes which address the key is sent to. An empty id quietly lists every receipt. The reply's `request_id` is never compared with the one asked for: asking for `r1` printed a receipt for `other`, with exit 0.\n3. **Low, `receipts.py:55`.** A body of `[]` or `{\"receipts\":[]}` prints no row at all, though the docstring promises one JSON row per outcome.\n4. **Low, `receipts.py:48`.** On the network-error path, a missing `--last-known` file, or one containing `NaN`, crashes with exit 1 and the error row is lost.\n5. **Low, `guard.py:85`.** `--max-tokens` accepts `1_6`, ` 16 ` and `١٦` (all read as 16) and sends the estimate, while `--cap` rejects the same typos with exit 2.\n\n**Coverage:** both production files (`guard.py`, `receipts.py`), the docs, and how the tests are set up. I ran the Access Control, Trust Gap and Asymmetry passes myself; no helpers were used. There is no Solidity here, so no Foundry proofs were written. I left out a few things I judged by design and didn't report:\n- Any non-empty prompt passes with a quoted input count of 1.\n- The quote's model isn't checked.\n- A key file containing only `12345` or `null` is refused as JSON.\n\nNothing outside spend-guard was reviewed.","treeHash":null,"usage":{"cachedInputTokens":299339,"cost":{"source":"runtime","usdMicros":714811},"inputTokens":18,"model":"claude-opus-5-5","outputTokens":15433,"runtime":"claude","turns":9,"wallClockMs":171732}}],"verification":[]}
