- on pass 1 is not a zero. Novelty, churn, thrash and surprise measure change against a previous pass, and pass 1 has none.
None. Every decision followed the engine’s advice.
| Pass | Predicted churn | Actual churn | Surprise | Claim |
|---|---|---|---|---|
| 1 | 0.45 | - | - | Pass 1 enumerates target modules and seeds initial findings. |
| 2 | 0.35 | 0.50 | 0.15 | Pass 2 verifies and retracts Pass-1 false positives against dev and grades remaining module to reach coverage 1.00. |
| 3 | 0.02 | 0.00 | 0.02 | Pass 3 expects near-zero churn after Pass 2 falsification and full unit coverage. |
| 4 | 0.00 | 0.00 | 0.00 | Pass 4 expects 0 deltas and Rule 6 convergence. |

Do: Add issueSessionCookie and verifySessionCookie in auth-service/server.js signing an expiration unix timestamp and a short HMAC fingerprint of USERNAME:PASSWORD_HASH (authenticated.<exp>.<fingerprint>), verify both in handleVerify, validate COOKIE_MAX_AGE as a positive integer at startup, and add unit tests in auth-service/test.js.module.web.ssetransportpackages/server/src/adapters/web/transport.ts
const bufferedEvent = { data: event, timestamp: Date.now(), liveWritePending: true }, awaits Promise.all(writes), and sets bufferedEvent.liveWritePending = false on that specific entry before acknowledging or replaying buffered events.

f-0003 (module.auth.server) - Potential open redirect via rd parameter in auth-service/server.js · retracted in pass 2 by the skeptic: Falsified on direct code inspection: isSafeRedirect(rd) in auth-service/server.js:62-65 enforces /^\/[^/\]/.test(rd) && !rd.includes(“://”), blocking //, /\, and scheme redirects.f-0002 (module.auth.server) - Double decodeURIComponent hypothesis on GET /login and POST /login rd parameter · retracted in pass 2 by the skeptic: Inspected auth-service/server.js:157-161 and 166-170: handleLoginPage does not call decodeURIComponent on rd; it passes encodeURIComponent(rd) into the hidden form field, which is why handleLogin calls decodeURIComponent(params.get('rd') ?? '/') once on form submission.f-0005 (module.web.ssetransport) - Hypothesis that SSETransport clears liveWritePending across all buffered entries · retracted in pass 2 by the skeptic: Inspected packages/server/src/adapters/web/transport.ts:215-241 on dev: emit holds a reference to its own bufferedEvent object and sets bufferedEvent.liveWritePending = false on that single entry only.dev to verify which hypotheses hold.signCookie('authenticated') with no server-side expiry or credential-rotation binding) is directly reproducible against auth-service/server.js:145-146, 180, 183.dev to grade module.web.ssetransport.verifyCookie / verifySessionCookie enforces COOKIE_MAX_AGE server-side and invalidates cookies when AUTH_USERNAME or AUTH_PASSWORD_HASH changes closes a real session-lifetime gap for self-hosted deployments.Resolution: 1 edit (plus 4 findings seeded by ponder grade before the argument).
isSafeRedirect at auth-service/server.js:62-65 blocks //, /\, and ://), f-0002 (handleLoginPage at line 160 encodes rd via encodeURIComponent(rd) rather than decoding it twice), and f-0005 (transport.ts:215-241 on dev sets bufferedEvent.liveWritePending = false on the single entry). Retracting f-0003, f-0002, and f-0005.f-0001 in auth-service/server.js (issueSessionCookie and verifySessionCookie with authenticated.<exp>.<credentialFingerprint>) and unit tests in auth-service/test.js.f-0006, score 5 note) so all 3 enumerated modules reach coverage 1.00.Resolution: 1 add, 3 delete.
issueSessionCookie and verifySessionCookie are minimal and backwards-compatible with existing signCookie/verifyCookie exports. Holding silence (0 deltas).Resolution: no deltas.
Resolution: no deltas.
