README accuracy follow-up. 1 The README says 80 tests and 20 conformance checks; the real counts are 94 and 22. Replace hard-coded counts with wording that will not go stale, or correct them.

2 The step-3 402 response row omits input; show the real 402 body fields including input. 3 Extend test/readme.test.ts so it runs the README's conformance commands and the library snippet too, not only the hand-run block. Add a CHANGELOG.md entry listing each item and what changed.

    Updated the README to remove hard-coded test counts, include input in the 402 response, and use the test bearer token in the library example. The README test now runs all three conformance commands and the library snippet. Each change is recorded in the changelog. The experimental label remains in place.

    npm test passed: 96 tests, 0 failures.

    Review complete. .imd-findings.json holds 4 findings; no project files were changed (git status shows only the untracked findings file).

    What I ran and confirmed

    Every README command, against the committed dist/:

    • npm ci --offline → installs from vendor/npm, no network. npm test → 96 pass (94 before this commit + the 2 new README tests), no hard-coded count left anywhere in README/src/dist.
    • npm start on 8402, then the whole "Try it by hand" block verbatim via bash -eu -o pipefail → exits 0, submit returns 402, order moves to payment_pending.
    • npm run conformance, … --flaky, … --url http://127.0.0.1:8402 → each prints 1..22, # pass 22, # fail 0.
    • The "Use as a library" snippet → id set, submit.status === 202.
    • node dist/cli.js vectors | diff - fixtures/vectors.json → identical. Bearer token, payer key/address and payTo in the README match src/fixtures.ts. --help, /, openapi.json and package.json all still carry the experimental notice.
    • Real 402 body: top-level keys are exactly x402Version, resource, accepts, quote, requesterScopeHash, resourceUrl, input — the row now matches. Rows 1–2 (201/200/409/422/401/403/404), the check-response keys, /requests/import and x-imd-actions all match the README. A fresh tsc of src/ diffs clean against dist/.

    Findings, by severity

    1. medium — README.md:181 claims the conformance suite covers "admission refusal". No check does: stale does not appear in src/conformance.ts, and none of the 22 TAP names is an admission refusal. The sentence was edited by this commit (count removed) and still carries the stale claim.
    2. low — README.md:75 the 402 row says input, but the body carries the prepared input ({"contracts":[],"github":false,"objective":"Say hi."} for a client that sent {"objective":"Say hi."}). The CHANGELOG says "prepared"; the README doesn't.
    3. low — README.md:132 (and :144) "next GET → admitted" is off by one: getRequest builds the view before advance(), so the triggering GET still returns admission_pending. The executing job state is never observable over HTTP for job.open. Doc wording only — server behaviour is out of scope.
    4. info — test/readme.test.ts:83 the library-example test resolves "imd-mock" to committed dist/ via package self-reference, while the sibling tests run src/; npm test never rebuilds dist/, so this test can go stale silently. In sync today.

    Nothing in the task's three items is broken as delivered; the defects are leftover inaccuracies in the paragraph and table this job was meant to make accurate.

    • mediumREADME says the conformance suite covers "admission refusal"; no check doesREADME.md:181

      The paragraph this commit edited (it removed the stale '20 checks' count on line 177) still lists 'admission refusal' among the things the suite covers. None of the 22 checks in src/conformance.ts exercises admission refusal: the only admission-refusal path in the mock is the [stale] marker (src/server.ts:407), the string 'stale' does not appear anywhere in src/conformance.ts, and no check name or assertion mentions admission being refused.

      The next sentence ('the mock refuses anything the suite refuses') makes the gap material: a client author reading this expects the suite to model an admission refusal they can test against, and it does not. The same count-free sentence was the whole point of task item 1, so the stale claim survived an accuracy pass of that exact line.

      grep -c stale src/conformance.ts prints 0; grep -n -i 'admission' src/conformance.ts matches only check 17's '200 with the admission result' and check 21's 'admission.result points at a public job'.

      Run npm run conformance and read the 22 TAP names: none is an admission refusal.

      A server that admitted every [stale] input unconditionally would pass all 22 checks, contradicting line 181.

      Expected: either a conformance check that pays for an input containing [stale], polls, and asserts the refused admission (as test/server.test.ts:208 does outside the suite), or drop 'admission refusal' from the sentence.

    • low402 row documents `input` but the body carries the prepared input, not what the client sentREADME.md:75

      Task item 2 added input to the step-3 row. The field is there, but it is spec.prepare(body.input) (src/server.ts:256, stored into the challenge at :309), i.e. the input with the action's defaults filled in, not the object the client posted at step 2. CHANGELOG.md line 6 correctly says 'the prepared input field'; the README row does not say prepared, and nothing else in the README explains that job.open input gains contracts: [] and github: false.

      A client that follows step 4 ('check accepts[0] against capabilities and the quote') and also diffs the challenge's input against what it sent will see extra keys and may treat the challenge as tampered.

      Run the README 'Try it by hand' block as far as $ORDER_ID, then curl -sS -X POST "$BASE_URL/requests/$ORDER_ID/submit" -H "Authorization: Bearer $TOKEN" and read .input.

      Sent at step 2: {"objective":"Say hi."}.

      Returned in the 402 body: {"contracts":[],"github":false,"objective":"Say hi."}.

      Expected per the row: the same input.

      Fix is wording only, e.g. 'input (as prepared by the mock, defaults filled in)'.

    • lowState machine says the next GET returns `admitted`; the triggering GET still returns `admission_pending`README.md:132

      MockState.getRequest builds the response view first and calls advance() after (src/server.ts:463-468), so the read that triggers admission_pending -> admitted still answers admission_pending; admitted first appears on the read after. Line 144 ('job.open {objective} returns 202 and is admitted on the next read') has the same off-by-one.

      The second half of the row, 'a created job advances from executing to completed on a later read', describes a state a client can never observe for job.open: the jobId only becomes visible on the GET /requests/{id} that already completes the job, so every GET /jobs/{id} a client can make returns completed.

      Server behaviour is out of scope for this job (previous request said not to change it), so this is a documentation defect: the rows should say the transition happens after the read, and that executing is internal/not observable over HTTP for job.open.

      node --input-type=module -e 'import { startMock, ImdClient, TEST_BEARER_TOKEN, TEST_PAYER_KEY } from "imd-mock"; const m = await startMock(0, "127.0.0.1"); const c = new ImdClient(m.url, TEST_BEARER_TOKEN); const { id } = await c.pay("job.open", { objective: "Say hi." }, TEST_PAYER_KEY); for (let i = 1; i <= 2; i++) console.log(i, (await c.getRequest(id)).body.status); const r = (await c.getRequest(id)).body.admission.result; console.log("job", (await c.getJob(r.jobId)).body.state); await m.close();' (run from the repo root).

      Output: 1 admission_pending, 2 admitted, job completed.

      Expected from line 132/144: the first GET after the 202 returns admitted, and a first job read returns executing.

    • infoREADME library-example test exercises committed dist/, not the src/ the rest of npm test checkstest/readme.test.ts:83

      The snippet imports from "imd-mock", which Node resolves by package self-reference through package.json exports -> ./dist/index.js. npm test compiles src+test into .test-build but never rebuilds dist/, so this test validates the README against whatever dist/ was last committed, while the other README tests in the same file run src via startMock from ../src/server.js. dist/ is in sync today (a fresh tsc --outDir /tmp/x diffs clean against dist/), so nothing fails now; the test can only go stale silently.

      It also only resolves when cwd is the package root: the same command run from /tmp fails with ERR_MODULE_NOT_FOUND, which is fine for npm test but is why the cwd: ROOT option is load-bearing. Non-blocking observation; a cheap guard is to also diff a fresh compile against dist/ in npm test, or to run the snippet with the import rewritten to ../src/index.js.

      State: change src/index.ts line 17 from export * from "./fixtures.js"; to an explicit list that omits TEST_BEARER_TOKEN, and do not run npm run compile. npm test still passes all 96 tests (test/server.test.ts and test/payment.test.ts import TEST_BEARER_TOKEN from ../src/fixtures.js, and this test loads dist/index.js, which still exports it), even though the README snippet import { ..., TEST_BEARER_TOKEN, ... } from "imd-mock" no longer matches src. Expected: a README test that fails when the documented library surface and the source disagree.
