Run 3 rewrote the staged index THROUGH the relative symlink into the raw
checkpoint: the raw index.json was restamped with the stacked layout
(605 KB smaller), the raw verify then failed 143/144 and the overnight
run died before stacking. Two fixes:
- stack-qwen38-official-fp8.py: index/config writes are now temp+os.replace
(an atomic swap replaces the symlink itself; the raw tree stays pristine).
- build-frank-primary-rad.sh: the stage's index.json is COPIED like
config.json; only shards stay relative symlinks.
Replace the FreeToken PR587 endpoint (single-GPU: its TP=2 dies in the
pynccl.cu ROCm JIT) with the radiance engine on both R9700s, TP=2 via
libr4d's fused one-shot all-reduce. Official Qwen/Qwen3.8-Flash-Next-FP8
payload at native block-FP8 precision:
- scripts/build-frank-primary-rad.sh: staging (quantization_config drop =
plugin SELECTION law) -> checkpoint reshape -> rad-convert with ONE
--quant rule (PLE rtn fixed-scale); plan-only first.
- scripts/stack-qwen38-official-fp8.py: the two value-preserving reshapes
(experts byte-stacked into the plugin's stacked layout; PLE's 128
scaleless fp8 shards decoded to one bf16 shard with the checkpoint's own
scale; the rtn rule re-encodes at that same scale - codes round-trip
exactly and land the one-element scale plane the plugin declares).
- scripts/hfget.sh + verified download (131/131 shards sha256-match).
- froggeric v22.5 chat template vendored (--override-chat-template).
- serve script (pinned ledger: 2x40 GiB pools + 47.7 GiB PLE + prefix host),
TTM preflight fixed for kernels with pages_limit only (no pages_max -
an absent knob is skipped, not read as zero); pages_limit raised to
52,428,800 pages = 200 GiB on the host pre-cutover.
- root unit, relinked; deployer gates image digest + .rad floor 158,000 MiB
+ health; prometheus re-adds the /metrics job.
- rollback: tag frank-primary-freetoken-pr587-20261005 (FreeToken trio +
Dockerfile); payload + image stay on disk until the window closes.
deploy-remote.sh also carries the parallel session's frank-small payload
gates (swift15) - committed here per Frank's direction to commit the tree.
