The refresh path in cli.ts does not: it passes requestId: rid into classifyReceipt, whose first line (receipts.ts:55, `request_id: r?.request_id ?? ctx.requestId ?? \"\"`) substitutes the CLI argument whenever the receipt omits request_id or carries null. The merged receipt is then written to disk with request_id = rid, and the identity check at cli.ts:417-418 reads that substituted value, so identityOk is true. With state settled and settled_spend 0 the ledger row gets spend 0 / cap_charge 0, the day total drops from 0.186 to 0, and the receipt prints match=matches. The same substitution also happens on a non-200 refresh (rr.receipt is null): a receipt file that run.ts had stored with request_id \"\" (identity mismatch) is rewritten with request_id = rid, and `receipt ` then reports match=matches with the key_expired flag, erasing the recorded mismatch without any new evidence. Impact: an unidentified receipt (the exact case the run path guards against, and that test/audit-repro.test.ts covers only for run) can zero a holder's daily cap charge via a routine `receipt --refresh`, allowing further paid calls beyond the cap, and can turn a flagged receipt green. Fix: in the refresh path read `(rr.receipt as {request_id?: unknown})?.request_id` directly, mirror run.ts (null out settled, set chain_final false, keep request_id as the raw value or \"\"), and never let classifyReceipt's requestId fallback decide identity; on a non-200 refresh keep saved.request_id.","line":411,"path":"imd-flop/src/cli.ts","reproduction":"State: `init --seat 9001`, `link --token 9001 --agent 7`, `cap set 5`, one mock run whose receipt is state=estimated (ledger: state estimated, spend null, cap_charge 0.186).

The refresh path in cli.ts bypasses that guard: when the previous row's cap_charge is null or missing it computes reservation = 0 and appends a new latest row with cap_charge 0 and spend null. Because the latest line per request_id wins, the unusable row is superseded by a zero charge, spentToday no longer throws, and the next `run` is admitted with the attempt counted as free. No refresh of a receipt should be able to lower a charge that was never known; a conservative implementation either refuses to write when prev.cap_charge is unusable or keeps the unusable value so the guard still fires.

Every one was confirmed with a fail-first vitest probe run against a temp copy of the project. Each probe's source is embedded in its finding's reproduction field.\n\n**Medium**\n- **Refresh accepts an unidentified receipt as the call's own** (`imd-flop/src/cli.ts:411`). The run path refuses to settle unless the raw receipt request_id exactly equals the call id, but refresh passes the CLI argument into classifyReceipt, whose fallback substitutes it when the receipt omits request_id or carries null. A settled receipt with no request_id and settled_spend 0 drops the ledger charge from 0.186 to 0 and prints match=matches. A 401 refresh also rewrites a stored empty request_id into the call id, so a recorded identity mismatch turns green.\n- **Refresh rewrites an unusable cap_charge as 0** (`cli.ts:421`). The ledger guard deliberately refuses the next call when a latest row has cap_charge null. A plain `receipt --refresh` appends a superseding row with cap_charge 0, and the next run is admitted with provider calls going through.\n- **Paid response lost on a second scan hit** (`imd-flop/src/run.ts:257`). When a gateway usage object has a key containing a dot and a hex-shaped value, redaction cannot clear the finding because setNull re-parses the dotted path. The second write throws after the paid call, so no response file, no receipt and no final ledger row are written. Exit code 5 with the scan message.\n\n**Low**\n- **stdout prints receipt fields the file redacted** (`run.ts:269`). A 64-hex request_id or bearer-shaped correlation_id is nulled in the receipt file but printed verbatim by both `run --json` and plain output.\n- **Refresh never converges from an unknown settled amount** (`cli.ts:416`). The ledger append is gated on state change only, so a settled receipt that moves from NaN to 0.05 updates the file but never the ledger. Conservative, but `receipt --json` then shows settled 0.05 against ledger_spend null forever.\n\n**Checked and found sound**: receipt identity in run.ts, fail-closed totals in sumCharges, the lock spanning cap check through append including re-entrant refuse, stale-lock reclaim only on a provably dead same-host owner, `--timeout-ms` validation, timeout and pre-send classification, and reservation handling for unresolved or rejected settlements.\n\n**Test limitations to note**\n- The existing suite passes 121 of 122 here. The one failure, the chmod-based refresh test in audit-v3, fails only because this sandbox runs as root and a read-only ledger stays writable. That is an environment artifact, not a code defect.\n- Coverage gaps the findings expose: the identity cases in audit-repro cover only run, not refresh. No test exercises refresh over an unusable ledger row. The stdout-withhold tests cover response text but not receipt fields.","treeHash":null,"usage":{"cachedInputTokens":1108513,"cost":{"source":"runtime","usdMicros":5363992},"inputTokens":322,"model":"claude-fable-5-1","outputTokens":45494,"runtime":"claude","turns":30,"wallClockMs":657192}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"5739ce0d803a43cd","findings":[{"citation":"resolved","description":"ledger.ts sumCharges() throws UnusableLedgerCharge when any latest row for the day has a cap_charge that is missing, null, non-numeric, negative or non-finite, and run refuses the next call (exit 3, 'ledger cap_charge unusable; next call refused'). The refresh branch of the receipt command undoes that: when the refreshed state name differs from the ledger row's state (any 404/401/network error gives state null, and 'sent' -> 'estimated' is the normal case), it appends a new latest row for the same request_id whose cap_charge is `prev.cap_charge` if finite, else literally 0 (line 421), and line 425 writes that 0. The next run then sums 0 for that attempt and passes. A single `imd-flop receipt --refresh` (mock needs no --live; flop with --live gets the same result from any gateway reply) converts a refused ledger into a passing one with no operator decision and no record that the charge was unknown. Rows without cap_charge are exactly what a ledger written by the pre-v3 version of this tool contains, so the upgrade path is affected.

The findings file at the repository root holds six substantiated findings, each with a failing input and a runnable reproduction. The existing suite passes on the pinned commit, and every reproduction I wrote fails on it.\n\n**What I found**\n\n- **Medium, cli.ts:421.** `receipt --refresh` rewrites an unusable ledger `cap_charge` as 0. A ledger row with a missing, null or non-numeric charge makes `run` refuse, as the prior fix intended. One refresh of that request id appends a new latest row with charge 0, and the next run passes and sends. Rows without the field are what a pre-fix ledger contains, so the upgrade path hits this.\n- **Medium, cli.ts:417-418.** The refresh identity check reads the classified receipt, and `classifyReceipt` falls back to the queried id when the gateway receipt has none. Two effects. A 200 receipt with no `request_id`, state settled and amount 0 releases the reservation and reports a match. Any non-200 refresh, including the 401 key-expired state the project's own bug report documents, overwrites a stored identity-mismatch receipt with our id, so `receipt` and `status` show \"matches\" from then on. The live client library's schema blocks the first shape but not the second.\n- **Low, cli.ts:416.** Refresh appends to the ledger only when the state string changes. A settlement learned later under the same state name is never booked, so the receipt file and the ledger diverge silently and the reservation stays charged against the day.\n- **Low, run.ts:167.** The ledger `day` is fixed before the estimate call, while the cap check uses the current day under the lock. A run crossing 00:00 UTC is booked to the old day and never counts against the new day. With a 0.2 cap, two 0.186 reservations are accepted.\n- **Info, audit-v3.test.ts:277.** `withLedgerLock` releases before an async callback resumes. Production use is synchronous and safe, but the in-process lock test passes without exercising the lock.\n- **Info, ledger.ts:127.** Lock timeout and contention exit with code 1 and a bare message, not a refusal code with \"refused locally, nothing sent\". Confirmed by holding the lock from a live pid.\n\n**What held up under review**\n\n- Run-time receipt identity, the reservation held while spend is unknown, settled-zero handling, the cap check through the sent-row append under the lock, timeout classification and the abort signal passing through the client all behave as specified.\n- `--timeout-ms` validation rejects every malformed form I tried. The response-file scan fallback keeps the paid response in all cases I could construct. The child-key mint uses its own fixed 15 second timeout independent of the flag, which is a note, not a defect.\n\n**Scope and limits**\n\n- Mock and injected providers only. No gateway, RPC or paid call was made, and nothing outside the repository was changed.\n- One unverified lead: if gateway usage ever carried a key containing a dot or bracket and that value tripped the secret scan, the redaction path parser would miss it and the second write would throw after the paid call. I could not substantiate a realistic input, so it is not in the file.\n- Requester payer mode has no aggregate bound beyond the per-call cap and the budget typed on each invocation. The README documents this as an assumption, so it is recorded here rather than as a finding.\n\nThe reproductions live under `imd-flop/test/scratch/` and the two medium findings carry their vitest source in the `proof` field.","treeHash":null,"usage":{"cachedInputTokens":2245315,"cost":{"source":"runtime","usdMicros":6635716},"inputTokens":482,"model":"claude-fable-5-1","outputTokens":48549,"runtime":"claude","turns":46,"wallClockMs":754784}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"fa4b91aed45c94fa","findings":[{"citation":"resolved","description":"Merged from audit_flow, audit_math, audit_permissions and audit_economics (same root cause). run.ts:262-268 decides identity on the raw gateway receipt (`rr.receipt.request_id === requestId`).

(a) HTTP 200 receipt with request_id absent or null: request_id becomes rid, identityOk at cli.ts:418 is true, and with state settled / settled_spend 0 the appended ledger row has spend 0, cap_charge 0, releasing the 0.186 FLOP reservation, so the daily cap admits one more padded quote per such refresh; the receipt is also saved with request_id = rid and shows match 'matches'. (b) Any non-200 refresh (404, http 0, 401 api_key_expired): merged takes c.request_id = rid, overwriting a stored '' or foreign request_id that run.ts recorded as an identity mismatch, so `receipt ` and `status` report 'matches' permanently without the gateway ever confirming the id. Both contradict the rule that request_id must match exactly, which run.ts already enforces. For the live FlopProvider, case (a) depends on what the @flop-labs/client response validation allows (not verified here); case (b) only needs a non-200 answer. Fix: derive identity from `rr.receipt?.request_id` exactly as run.ts does; when identity fails keep settled null, chain_final false and the stored/raw request_id; on a non-200 refresh keep saved.request_id; never let classifyReceipt's ctx fallback feed identity or settlement.","line":417,"path":"imd-flop/src/cli.ts","proof":"/**\n * Vitest reproduction (imd-flop/test/scratch/).

I kept 14, and the only one I dropped is a design decision rather than a defect (see the end).\n\n**Medium (each carries a proof file that fails on the current code)**\n1. **Refresh identity check uses a filled-in id** (`src/cli.ts:417`). This was reported by all four specialists. In the refresh path, `classifyReceipt` replaces a missing request_id with the id you typed. So a receipt with no request_id (or a null one) and settled_spend 0 releases the 0.186 FLOP reservation and shows \"matches\". Any non-200 refresh also turns a recorded identity mismatch into \"matches\". `run.ts` checks the raw receipt and gets this right; refresh doesn't. I ran the specialist's proof and it fails for the stated reason (3 cases).\n2. **Refresh turns an unusable cap_charge into 0** (`src/cli.ts:421`). The ledger refuses new runs when a cap_charge is missing, null or not a number. A routine `receipt --refresh` overwrites that row with cap_charge 0, and the next run is let through. I ran the specialist's proof and it fails (3 cases).\n3. **Paid response lost when a key contains \".\"** (`src/run.ts:257`). Redaction can't reach a key like `usage[\"a.b\"]` because it splits paths on dots. The second write then throws, and the run exits 5 with no response file, no receipt and no final ledger row. This breaks the \"no paid response is lost on a scan hit\" requirement. I wrote the proof.\n4. **Clean completion text discarded on any scan hit** (`src/run.ts:255`). A hit in an unrelated field such as `usage.note` throws away completion text that contains no secret. I wrote the proof.\n\n**Low**\n- **Refresh only writes the ledger when the state name changes** (`cli.ts:416`). A settlement amount that arrives later under the same state is never booked.\n- **Refresh has no redaction fallback** (`cli.ts:413`). A key-shaped value in the receipt makes every refresh exit 5, so that settlement can never be booked.\n- **Key-shaped receipt state aborts a paid run** (`run.ts:294`). The final ledger row uses the unredacted state, so the run exits 5 with empty output.\n- **Redacted receipt fields still printed** (`run.ts:269`). A foreign 64-hex request_id or a Bearer-shaped correlation_id is removed from the receipt file but printed on stdout.\n- **Midnight UTC** (`run.ts:167`). A run that crosses midnight is checked against the new day and booked to the old one; I measured 0.372 booked against a 0.2 daily cap.\n- **Cap object without numbers** (`run.ts:151`). A cap entry like `{}` in config.json turns off both cap checks.\n- **Child-key mint network failure** (`gateway.ts:45`). It's recorded as timeout_unknown, and its reservation then counts against the daily cap even though nothing was sent.\n\n**Info**\n- **Ledger lock with an async callback** (`ledger.ts:150`). The lock is released before the async work runs. Production code only passes a synchronous callback, so it isn't affected, but the audit-v3 lock test passes without actually testing the lock.\n- **64-hex job id** (`run.ts:119`). It passes argument validation but is then rejected with exit 5 and a secret-scan error.\n- **Lock timeout exit code** (`ledger.ts:127`). It exits with 1 (generic error) instead of a \"nothing sent\" refusal code.\n\n**Dropped:** with `payer=requester`, spend doesn't count toward the daily cap. That is intended, documented and covered by a test, so it's a trust assumption rather than a defect. While there's no requester payment rail, the seat's own key still pays for those calls.\n\n**Checked and fine:** `--timeout-ms` validation (`cli.ts:61-67`) rejects non-integers, values out of range and non-digit input.\n\n**Coverage:** I used the specialty guides as my own review passes, with no helpers.

The refresh path does not: it classifies first, and classifyReceipt (src/receipts.ts:55) fills request_id with `r?.request_id ?? ctx.requestId`, i.e. with our own id whenever the gateway receipt has no request_id or a null one. cli.ts:417-420 then checks identity against that already-substituted value, so identityOk is true, settledKnown is taken from the receipt, and the ledger row is rewritten with spend = settled_spend and cap_charge = settled_spend. With settled_spend 0 the 0.186 FLOP reservation is released and the day's total drops to 0, so the daily cap can be exceeded by one padded quote per such refresh. The same receipt in the run path is treated as an identity mismatch (test/audit-repro.test.ts 'id-missing'/'id-null' cases), so run and refresh disagree on the identity rule the fix commit introduced. Second scenario, same root cause: when the refresh read is not HTTP 200 (404, 0, 401), classifyReceipt(null, {requestId: rid}) also yields request_id = rid and the merge at cli.ts:412 overwrites a saved foreign request_id (e.g. 'foreign-request' recorded by run) with our own id, so the saved receipt silently changes from match 'mismatch' [receipt identity mismatch; chain-final green blocked] to 'matches'. Fix: in the refresh path derive identityOk from the raw receipt (`rr.receipt?.request_id`) exactly as run.ts does, and when identity fails keep settled null, keep the saved request_id, and do not lower cap_charge; for non-200 reads do not overwrite request_id from the fallback.","line":411,"path":"imd-flop/src/cli.ts","reproduction":"Mock provider only, no network.

In both cases a later refresh that returns the same state 'settled' with the correct request_id and a finite settled_spend updates the receipt file (settled 0.05, match 'matches') but appends nothing to the ledger, because the state did not change. The ledger then permanently says spend null / cap_charge 0.186 while the receipt says settled 0.05, `receipt --json` prints settled 0.05 next to ledger_spend null, and no 'receipt and ledger disagree' status is raised.

No repository file other than `.imd-findings.json` was created or changed, and the project's own suite passes at this commit (122 tests).\n\n**What I found, by severity**\n\n- **High, receipt --refresh identity fallback** (`imd-flop/src/cli.ts:411`). The refresh path classifies before checking identity, and classifyReceipt substitutes our own id when the gateway receipt has no request_id or a null one. A refreshed receipt with state settled and settled_spend 0 and no request_id then releases the 0.186 reservation to 0 and shows match \"matches\". The run path rejects the same receipt. A non-200 refresh also overwrites a saved foreign request_id, erasing a recorded identity mismatch.\n- **Medium, refresh ledger gate** (`cli.ts:416`). The ledger is only rewritten when the state string changes. A known settlement arriving under an unchanged \"settled\" state is never booked. The receipt says 0.05 while the ledger stays at spend null and 0.186 forever, with no disagree status.\n- **Medium, benign text discarded** (`run.ts:255`). A scan hit in usage nulls the completion text even though only usage.note was flagged. The paid output is written nowhere.\n- **Medium, unredactable path** (`run.ts:257`). A flagged usage key containing \".\" cannot be addressed by setNull, the second write throws, and the run aborts after the paid call with no response file, no receipt and no final ledger row.\n- **Low** findings cover the UTC day stamped before the estimate but checked after it (one extra call per midnight), a malformed cap object passing the \"cap required\" guard and disabling all cap checks, a child-key mint transport failure booked as timeout_unknown and burning the cap, payer=requester voiding the daily cap while the same seat key pays, and refresh having no redaction fallback so a hex settled_spend_raw makes that settlement unbookable.\n- **Info**: a 64-hex job id trips the ledger scan and can never be served.\n\n**Coverage and limits**\n\nThe lock from cap check through append, the --timeout-ms validation, padQuote rounding and the ledger fail-closed sums held up under the inputs I tried and produced no findings. All reproductions use the mock provider seam. The live FlopProvider, gateway and chain paths were read but not exercised against a network, so the mint-failure finding is shown at the unit level plus the run-level classification rather than end to end. No Foundry proofs were written since the subject is TypeScript.","treeHash":null,"usage":{"cachedInputTokens":2013716,"cost":{"source":"runtime","usdMicros":6325161},"inputTokens":450,"model":"claude-fable-5-1","outputTokens":50446,"runtime":"claude","turns":41,"wallClockMs":731898}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"3a720671678111bc","findings":[{"citation":"resolved","description":"run.ts (lines 262-268) reads request_id from the raw gateway receipt and treats a missing or null id as an identity failure (settled stays null, reservation held).

Findings are in `.imd-findings.json` at the repository root (six entries, valid JSON; git ignores the file locally, which is expected). No source files were changed. Dependencies were installed only to run checks, and the scratch tests I used were removed.\n\n**What I found**, each reproduced against the tree with the project's own test harness:\n\n- **Medium, receipt --refresh trusts a receipt with no request_id.** The refresh path derives identity from the classified object, where a missing or null id is replaced by the looked-up id. A settled receipt with no `request_id` therefore passes the identity check, the ledger row becomes `spend 0, cap_charge 0`, and the reservation is released. The run path already handles this case correctly, so the prior fix is incomplete for refresh. See `imd-flop/src/cli.ts:417`.\n- **Medium, refresh converts an unusable cap_charge to 0.** A ledger row with `cap_charge: null` blocks the next run, as intended. Running `receipt --refresh` appends a new row with reservation 0, and the next run passes the cap check and reaches the provider. See `imd-flop/src/cli.ts:421`.\n- **Low, final ledger row uses the unredacted receipt state.** A key-shaped `state` value makes the final append throw after paid work. The run exits 5 with no request id printed, while the response and receipt files exist. See `imd-flop/src/run.ts:294`.\n- **Low, redaction cannot address a key containing a dot.** With `usage['cost.note']` holding hex, the fallback response write throws too. No response file, no receipt, no final ledger row. See `imd-flop/src/secrets.ts:93`.\n- **Low, the lock releases before an async body finishes.** Production passes a sync closure, so run is safe today, but the audit-v3 lock test passes vacuously because its append happens before its await. See `imd-flop/src/ledger.ts:150`.\n- **Info, a 64-hex job id is refused by the ledger scan** before any call, with a misleading secret-scan error.\n\n**Checks that held up:** `--timeout-ms` validation rejects NaN, 0, negatives, decimals, and out-of-range values before any ledger write. The run path's identity check, the fail-closed sum of charges, the lock from cap check through the pre-call append, and the reservation-not-lowered rule all behaved as specified in the scenarios I exercised.
