- Dictionary lookup index is per VM (vm->fc_index, struct SfFcIndex):
was one global index rebuilt whenever a different VM was searched, and
heat reorganization could reorder another VM's buckets. Allocated on
first lookup, freed by vm_cleanup(); allocation failure counted/logged,
lookup falls back to a newest-first dictionary walk.
- PRNG: still one stream, stepped by compare-and-swap; SEED one store.
- state_variable removed (write-only; STATE is vm->mode).
- Sweep additions (Captain Bob's ruling): heartbeat_export.c delta
last-values moved into each VM's HeartbeatState (were statics shared by
every VM -- wrong across VMs today); TOP-WORDS list heap-sized per call
(was static [1000]); inference_outputs_to_string() takes a caller
buffer; three failure counters atomic; crc64 table published with
release/acquire.
- Confirmed, unchanged: g_runtime compiled out of the kernel,
g_hotwords_cache unreferenced, ttf cache core-0-only.
- Probe (removed): every VM has its own index; two VMs searched
alternately 2x5000 lookups: 0 rebuilds, 0 wrong-VM results, all three
ISAs.
- Standard sequence on amd64/aarch64/riscv64: dict_hash set unchanged,
G byte-identical, MINT/WIREBIND/USE ok, conservation true, 0 idle growth.
