Adds a 41-LOC cvar-gated probe (audit_handle_lifecycle) that emits a one-shot
0x300-byte hexdump of the silph::WorkerCtx context the first time KeSetEvent
fires into the silph UI PKEVENT cluster (0xBCE25200..0xBCE25300 in current
builds). Recovers ctx_base by anchoring on the canonical layout (events at
ctx+0x54/+0x64/+0x74/+0x84 with 16-byte stride; ctx_base = ev_addr - (ev_addr
- 0xBCE251C0)). Also emits an explicit per-slot summary of the 8 candidate
KEVENT headers at +0x54..+0xC4 for sanity.
Produces 48 DUMP rows + 8 slot rows in canary.log on the first triggering
KeSetEvent. Guarded by std::atomic_bool so subsequent fires are silent. Used
by iterate 2.BF context-replication in ours: we need the live [ctx+0] vtable
pointer and the 4 quiet/4 active KEVENT slot config to synthesize a matching
WorkerCtx and spawn the four sub_82506xxx entries.
