publish() now guards width/height alongside format (CopyResource needs matching DIMS too, else garbage): drops a surface whose descriptor no longer matches the host ring (a fullscreen game mode-set the display) AND logs the actual descriptor once per mismatch episode, so a repro shows exactly what changed (GB1/Stage-0 diagnostic + the Stage-2 width/height guard).
log.rs: a process-lifetime, flushed, Mutex-shared append handle (opened ONCE) replaces the per-call open/append — so the swap-chain WORKER thread's lines land. They were hidden (per-call open raced the control thread / could fail under the worker's restricted token), which is exactly why a game-break repro showed no swap-chain-processor lines (bug doc S3). This is the observability foundation the bug doc gates Stage S (S1/S2 driver resilience) on.
Needs a driver rebuild + re-vendor to deploy (separate from the GB1 host-only fix). Stage 3 (trim default_modes) deprioritized: GB1 recovers from mode-sets, and trimming risks the live display-activation path.
Verified: driver workspace builds clean on the RTX box (.173).
