- ggml: read-only mmap module (unix-gated) + two-region Context (mapped
weights / dirty caches) + segmented Metal buffer binding; llama loads
GGUF weights as file-backed clean pages (jetsam-exempt) with owned-arena
fallback (MAKEPAD_LLAMA_NO_MMAP=1). Route app dirty footprint 12GB -> 4-7GB;
model load becomes lazy page-in; A/B byte-identical on 4B + 9B.
- llama: fix graph-cache keying corruption — a graph keyed wider than the
KV cache corrupted attention for any prefill batch >= 2 (flash op reads
permute-node dims baked at build; view reconfigure never reached the
kernel; masks were written cache-narrow). Masks now always fill the full
graph key width and graphs key by 1024-buckets; reconfigure path removed.
Verified byte-exact vs per-length reference across batch 1/2/8/64/512,
short+long prompts, mmap on/off, plus a two-session concurrency probe.
- voice: passive VoiceWaves no longer register the global audio-input
callback (the invisible caption-bar wave stole mic audio — last
registrant wins — and spawned duplicate whisper workers); whisper back
to F16 default (voice Metal library has no quantized kernels; q5_0
failed every GPU matmul); raw transcripts render immediately.
- route: kokoro TTS voice output (speaker toggle; streams reply sentences,
announces nav maneuvers + arrival) with barge-in — voice activity on the
mic stops playback instantly; dispatcher context 8k -> 32k (hybrid KV is
12/48 layers, ~48KB/token); window caption bar suppressed under studio.
- llama-generate: --max-context/--prefill-batch-size + state fingerprints;
new llama_concurrent_probe bin.

Grid width for the non-flat unary path was ne01 while the kernel decomposes
tgpig.x into (ne0-chunk, row) — rows past ntg were silently dropped, masked
below the 32768-element flat-path threshold; silu on [8192, n] crossed it at
prefill batch 4 and corrupted qwen35 batched prefill. Grid is now
ne01 * ceil(ne0/nth). Adds metal unary/gated-delta-net/ssm_conv regression
tests, the llama-batch-probe bisect harness, prefill batch default 32, and
keeps the graph cache until a reserve-retry actually needs eviction.
