Matthew Stanley 13c5e0c5b5 stale-recompiler shard guard + exception-exit ring; Tomba menu wedge resolved
Root cause of the Tomba pause-menu wedge (loaded saves only): autocompiled
overlay shards were emitted by a recompiler binary OLDER than the last emitter
change, yet stamped with the CURRENT cg tag (compile_overlays derives the tag
from --runtime-include; nothing tied it to the emitting binary). The stale
shards corrupted the display-list task queue during load-game. NOT the
IRQ-resume class the prior handoff claimed - disproven with the new ring.

- recompiler: bake the emitter-source hash (shared canonical list
  runtime/codegen_hash_sources.cmake + hash_codegen.cmake) into psxrecomp-game;
  new --codegen-hash flag prints it (machine-parseable, pre-banner).
- compile_overlays.py: HARD-FAIL when the recompiler binary's baked hash
  differs from the cg tag hash it stamps (or the binary lacks the flag).
  Applies to both cache and --static modes. Closes the read==write-tag /
  stale-content drift class structurally.
- runtime.cmake: codegen-hash source list moved to the shared canonical file.
- interrupts.c: always-on exception-EXIT half added to irqctx_ring (take_pc,
  real_epc, exit_pc, escape reason, same-thread/restore flags, v1/ra
  saved-vs-exit, RestoreState redirect count) - proves per delivery which
  escape path fired and whether the interrupted GPRs were restored. Kept the
  same_thread_resume GPR-restore refinement (ring-verified equal-value in
  practice; faithful: hardware restores all GPRs on every exception return).
- debug_server.c: irqctx_ring dump extended with the exit-half fields.

Validated live: Tomba menu opens on loaded save (Stormy Mountain) with the
cache fully enabled after regenerating shards with a rebuilt recompiler
(build-cosim + build-prod caches). Guard verified positive and negative.
MMX6 gate passed: boot -> title -> opening cutscene -> gameplay handoff OK.

# 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.
