jpeg_prog_decode_ac_refine treated ZRL (run=15, size=0) as run=16 and
reused the skip loop, which kept consuming correction bits for non-zero
coefficients after the 16th zero-history coefficient. Those bits belong
after the next Huffman symbol (ITU T.81 G.1.2.3, libjpeg
decode_mcu_AC_refine), so the bitstream desynchronised: many progressive
JPEGs, including plain `cjpeg -progressive` output, failed to load or
decoded with wrong pixels.
Skip `run` zeros while refining non-zeros on the way, write the new value
(0 for ZRL) at the next zero, and stop, matching libjpeg's structure.
Add tests/test_image_decode with two cjpeg-generated fixtures that fail
on the old decoder (wrong pixels for grayscale, NULL for 4:2:0) and are
bit-exact with djpeg after the fix. Wire it into `make test`.
(cherry picked from commit 50ed0a4c73)
Implement qwen4exp loading, tokenizer and chat formatting, PLE sidecars,
Metal text and vision graphs, built-in MTP, and recurrent KV persistence.
Integrate the CLI, agent, server, download targets, and conversion tools.
Preserve the native Q4_1 encoder, Q4_K accumulation guard, and shared
quantizer build target. Keep exact-MTP rewind and vision-cache row-width
fixes. Persist valid logits and recurrent state at completed prefill chunks,
and reuse Qwen text-answer history when tools clients omit reasoning.
Retain exact reasoning replay and test continued checkpoints, cancellation,
cache eviction, and restart reuse with and without reasoning_content. Include
reproducible charts and measurements comparing throughput before and after
the checkpoint fixes on M3 Ultra.
Add Qwen trunk steering and prompt activation capture, including GDN layers.
Keep the MTP predictor outside the 48-row bank and preserve prompt dumps
through one-token prefill tails and multi-row speculative verification.
Recover Chrome target creation and retain its last page target. Preserve
full agent transcripts in stripped-session format when KV no longer fits,
while retaining the newer automatic compaction and continuation logic.
Add steering/MTP/capture, Chrome CDP recovery, and full-session save/reload
regressions. Adapt the intended changes from fork PRs #13 and #7.
Reconcile with antirez main bd66c40, preserving DeepSeek v4.1 model IDs,
tool syntax, session state, and Metal kernel dispatch. Exclude superseded
engine code and prototypes.
