The post-exception IRQ cooldown counted psx_check_interrupts CALLS. A call is a backend-dependent unit: compiled checks at block edges (plus extra sites like a `jr ra` return transition), the dirty-RAM interp checks per-instruction. So the per-call countdown reached zero at a DIFFERENT guest cycle in each backend, the next IRQ was delivered at a different cycle/EPC, and the two backends forked (cosim first-divergence cp 3259 @ cyc ~213.5M). Convert the cooldown to a guest-cycle DEADLINE (post_exception_cooldown_until): guest cycles advance identically in both backends (shared, ruler-validated cost model), so the delivery decision is now backend-independent. Magnitudes preserve prior breathing room (claimed ~= old 8 blocks, unclaimed ~= old 500 blocks). Also: - gpu: GP1(00h) reset no longer clears VRAM. VRAM survives a GPU reset on real hardware; only power-on gpu_init() clears our backing store (gpu_reset_state). - codegen hash: include the emitter/translator/discovery .cpp TUs, not just their .h. A change confined to full_function_emitter.cpp altered generated dispatch+overlay code while leaving the hash unchanged -> stale overlay-cache hazard (same class as the ws-emission-not-in-hash gap). - debug: ring-buffer WINDOW-QUERY primitives -- frame_lo/frame_hi filters on wtrace/mmio dumps + a capture-freeze frame so a causal window's tail is not evicted by a post-window event storm before a probe reads it (query the always-on ring for the window of interest, not arm-and-hope).

# codegen_hash_sources.cmake — the CANONICAL list of recompiler codegen sources

|
# folded into the overlay cache tag hash (hash_codegen.cmake).
|
|
#
|
|
# Included from BOTH:
|
|
# - runtime/runtime.cmake (bakes the hash into the runtime's cg tag)
|
|
# - recompiler/CMakeLists.txt (bakes the SAME hash into psxrecomp-game,
|
|
# exposed via `--codegen-hash`)
|
|
# so the two hash computations can never drift by list divergence. Any file
|
|
# added to the emitter pipeline must be added HERE, once.

|
|
# Input: PSXRECOMP_CODEGEN_HASH_ROOT — the psxrecomp repo root.
|
|
# Output: PSXRECOMP_CODEGEN_HASH_SRCS — absolute paths to hash.
|

|
|
# NOTE: include the emitter .cpp translation units, not just their headers. A
|
|
# change confined to full_function_emitter.cpp (e.g. the 2026-07-03 Class-A
|
|
# shell-window overlay-dispatch fix) alters both generated dispatch and overlay
|
|
# code but left the hash unchanged when only the .h files were listed — a stale
|
|
# overlay-cache hazard (same class as the "ws emission not in cg hash" gap).
