Campaign reopen — iter8's "campaign-closing" status was contingent on
"mpv --hwdec=vaapi smooth", which doesn't hold against fresh-install
interactive testing. iter9 single-track scope:
- Bug #1 (libva-v4l2-request-fourier#1) only
- mpv H.264 fresh-login through ≥30s of decode without any of: cap_pool
double-init, REQBUFS EBUSY, REINIT bad-fd, OUTPUT ENOMEM
- Phase 0 will source-read cap_pool + request_pool + iter6 REINIT,
build a vo=null reproduction harness, prepare bisect against iter5
baseline, and a libva-direct C probe for minimal repro
Bug #2 (presentation green) is dmabuf-modifier-triage's job — peer
campaign opened 2026-05-08 at ~/src/dmabuf-modifier-triage/. README
cross-link now points at it.
