Integration branch: the interpreter-perf series (interpreter fallback +
additive shard autocompile + always-on production observability + the
fail-closed alias-body emitter fix) rebased-by-merge onto master's AOT
overlay generation (play-free extraction, bounded indirect discovery,
AOT recall, shadow-diff redesign).
Semantic-union highlights:
- gte.cpp: HEAD's direct-field marshaling fast paths kept; master's
s_gte_replay_sandbox guards grafted onto every affected site.
- psx_icache.c: HEAD's global tag array + fetch_miss split kept;
master's transactional shadow record/replay retargeted onto it.
- overlay_capture.c: HEAD's commit/retry/wait-pending pipeline kept;
master's durable history + autocapture APIs wired into it
(persist_history_snapshot fed from the immutable .d contribution).
- overlay_loader.c: master's interp-record/native-replay shadow-diff
redesign kept as base with HEAD's scheduler-bail hardening grafted
(new SHDIFF_SCHED divergence kind); strict manifest v2 parsing keeps
master's P pair-id lines; always-on native-call ring preserved.
- main.cpp shutdown calls BOTH overlay_autocapture_shutdown() and
overlay_capture_wait_pending() (the latter drains the preserve-write
FIFO the former does not).
- recompiler: master's generate_alias_group refactor retains the
fail-closed alias-body re-entry defaults from c85f1d1.
Validated on this tree: recompiler + runtime + tests build; all six
runtime unit tests PASS; interpreter perf guards PASS; recompiler
patch/structural tests PASS (l1 decoder oracle noise = 376 pre-existing
on both parents).
