Adds infrastructure to synthesise the silph::WorkerCtx that AUDIT-058/059 identified as never reached by ours' static-init chain (real chain entry sits in audit-059 round 9's wrong-vtable wedge at sub_82172BA0+0x1E8). Ctx layout follows round 5's live hexdump from canary: +0x00 vtable = 0x8200A1E8 +0x04 self +0x08 intrusive list head -> self +0x0C init flag = 1 +0x10 packed byte field +0x18 2x float ~1.0 (UI rates) +0x24 flag = 1 +0x28..+0x30 3x foreign-arena pointers (left NULL — see below) +0x54..+0x84 4x X_KEVENT auto-reset, state=0 +0x94..+0xC4 4x X_KEVENT manual-reset, state=1 (pre-signaled) +0x210..+0x250 4-entry intrusive work-ring, empty Worker spawn mirrors AUDIT-048's audio-worker pattern in xaudio_register_render_driver: per-worker allocate_thread_image + state.scheduler.spawn with r3 = ctx_ptr. Trigger fires at the first dat/* VFS open (ours' earliest is dat/files.tbl), which is when canary runs the equivalent chain. ROUND 18 OUTCOME — opt-in only: With workers spawned Ready (XENIA_SILPH_SYNTH=1), boot CRASHES at cycle ~5.5M with PC=0 on hw=1, just after worker_3 (entry 0x825065B8) spawns. Per task constraints this is STOP-and-report: the ctx fields +0x28/+0x2C/+0x30 (foreign heap pointers — canary's 0x30057018, 0xBCE25640, 0xBE568F00, distinct arenas per audit-059 round 7) are left NULL, and the worker bodies plausibly dereference one of them. Synthesising those is a fresh investigation (round 19+). With workers spawned Suspended (XENIA_SILPH_SYNTH=suspend), boot completes normally (11 spawns, VdSwap=1, KeSetEvent=2, KeReleaseSemaphore=1 — matches default baseline). The ctx remains materialised in guest memory at the logged VA for downstream probing. Default (env var unset): no synth, no regression.
