- First-run pickers now state exactly which user-supplied file is being
requested: an info box + step-numbered dialog title for the BIOS
(Step 1 of 2, SCPH1001.BIN) and the game disc (Step 2 of 2, named
game + accepted formats), each noting what it is NOT. Game name comes
from the loaded game config.
- event_ring recording is now compiled out under PSX_NO_DEBUG_TOOLS:
it is only readable via the TCP debug server (stripped in production)
and is not part of the freeze dump, so recording was pure hot-path
cost. All other rings were already no-op gated.
- Overlay autocapture (which writes the player-shareable
overlay_captures.json) is now enabled whenever overlay_cache is on,
no longer coupled to the dev-only autocompile command — player builds
produce the contribution file the README promises; the background
compile still requires a configured command and no-ops without one.
Production surface after this: no console (-mwindows), no TCP server,
no ring recording; keeps overlay cache + captures, freeze watchdog JSON,
and crash report.

Accumulated working-tree state for the overlay-JIT-cache phase, committed as a
checkpoint before the Bug A fix (next commit):
- event_ring.{c,h}: always-on unified event-timeline ring (IRQ deliver/gate/
raise, I_STAT changes, DMA kick/sched/done, ENQ/DEQ per source, exec-mode
tagged). Edge-recorded, eviction-bounded, survives a blue screen; dump via
event_ring_dump/_tail/_clear.
- cdrom.c: disc_speed="instant" no longer collapses every sector read to the
500cy floor (which flooded ~1100 DMA3 completions/frame and starved main
code). CDROM_INSTANT_PERIOD bounds sector IRQs to CDROM_INSTANT_MAX_PER_FRAME
(32)/frame. Known caveat: a transient ~1-2s reentry storm at boot frame ~210
still trips the watchdog once, then recovers.
- interrupts.c: claimed-IRQ cooldown is now per-source — SIO stays 0 (card
reads need back-to-back IRQs); DMA/VBLANK/timer get CLAIMED_PROGRESS_QUANTUM
(8) blocks of guaranteed main-code progress between deliveries. Root cause of
the instant-disc freeze: cooldown=0 let the block leader re-take the
exception before its body ran (pinned at the 0x8005A1D8 field loop).
- gpu/dma/memory/sio/timers/psx_cycles: event-ring instrumentation at raise/
kick/complete/schedule sites; g_event_step_conservative (single-cycle event
stepping A/B used to refute the event-granularity hypothesis for Bug A).
- overlay_capture.c, overlay_loader.h, crc32: capture/manifest plumbing for
per-entry validity (Inc3).
- recompiler: overlay-mode emission updates (code_generator, main_psx).
- tools: compile_overlays.py audit/patch updates; tomba_loadtest.py.
