2026-08-13 14:31:33 INFO    review: on_target=True stop=False guidance='Good — 5 families now, all on-target UAF in gf_m2ts_es_del. The new 5th family (poc_109) triggers via gf_m2ts_get_adaptation_field using a TEMI timeline descriptor in the adaptation field extension — a genuinely new trigger mechanism hitting the dangling ES through adaptation field processing. Families so far: (1) poc_092: packet processing, (2) poc_096: cleanup/teardown, (3) poc_100: PMT processing, (4) poc_105: parser reset via PCR discontinuity, (5) poc_109: adaptation field/TEMI descriptor. The adaptation-field direction proved fruitful — continue exploring related but distinct paths. Promising directions: (1) Other adaptation field extensions — try different descriptor types in the adaptation field extension (e.g., seamless splice, timing descriptor) that may dereference the dangling ES through different code paths. (2) SDT/EIT/other table processing — still unexplored; section handlers that iterate ts->ess. (3) Multi-program streams — two PMTs with overlapping PIDs causing cross-program dangling pointers. (4) PAT version changes — program removal via PAT version bump triggering ES cleanup. (5) Different stream_types on the dangling ES that take alternate code paths. (6) Splice point processing — if splice_countdown or splice-related adaptation field processing dereferences ts->ess. Avoid: further TEMI variants that only change descriptor content without altering the structural trigger. Also avoid re-hashing PCR-reuse or PMT-version-bump variations.' reasoning='All 5 families are UAF in gf_m2ts_es_del — on-target.
