# sylph-run.sh — run the ours xenia-rs emulator N times and report the standard
# intro-video oracles. Inherits any XENIA_* probe knobs from the caller's env
# (e.g. XENIA_FORCE_TID=24, XENIA_STARVE_LIMIT=16, XENIA_LOG_SIGNAL=0x40d10214).
#
# Usage:  [XENIA_*=... ] sylph-run.sh [runs] [n_instr] [timeout_s] [extra_grep_regex]
#   runs        default 6
#   n_instr     default 3000000000
#   timeout_s   default 180   (boot is DETERMINISTIC and reaches the intro
#                 movie's first on-screen frame at ~81s wall; the movie then
#                 plays reliably. The old 90s default sat ~9s above that point,
#                 so host-load wall-clock jitter cut some runs off just before
#                 the movie — the apparent "~1/3 of runs" flakiness. 180s clears
#                 it with margin. Guest-instruction execution is identical run
#                 to run; only wall time varies with host speed.)
#   extra_grep  optional ERE; matching stdout lines are saved per-run for ad-hoc inspection
#
# Always-on oracles: source-read 0x824ff708 count (>1 = feeder looped), decode-worker
# resumes (tid25 start_entry 0x82506588 / tid26 0x825065b8). Full per-run log kept under
# /tmp/sylph-run/.
