Setup script: pin updated 917519b → 64dd18b. Verified clean on tools-text
(75K + fp8 KV + MTP, PN8 enabled): verify-full.sh 8/8 + verify-stress.sh
tool-prefill OK. v7.64 release notes adopted: PN17 is Sandermage's anchored
version of our P104 sidecar (FA2 softmax_lse runtime clamp), PN19 sets
max_split_size_mb=20 during model load.
long-text.yml (218K + 0.985 + TQ3 + MTP):
- Genesis pin v7.64 (PN17 enabled, PN19 disabled — costs ~120 MiB KV pool
on Ampere consumer; the documented "200-500 MiB win on H100" is negative
on our hardware).
- Drops max-model-len 218000 → 205000 because PN17 reserves ~120 MiB of KV
pool space at boot ("estimated maximum model length is 206400" is the
engine pre-check failure mode otherwise).
- P104 sidecar (patch_fa_max_seqlen_clamp.py) kept mounted but env-disabled;
PN17 covers the same path via Sandermage's anchored fix. Flip the env
var back on if PN17 turns out not to cover turboquant_attn.py for some
config.
- Mounts new patch_pn12_compile_safe_custom_op.py — opaque torch.library
custom_op for the inductor-compiled forward_native FFN path that the
eager-mode forward_cuda sidecar can't reach (issue #16, mech B). Only
active when GENESIS_ENABLE_PN12_FFN_INTERMEDIATE_POOL=1; harmless when
off. Forward_native body simplified to a single static-guard branch on
module-level _PN12_ENABLED so Dynamo specializes at trace time instead
of compiling both branches (the else-branch's plain F.silu/mul lowers
to empty_strided_cuda, defeating the patch).
verify-stress.sh: fixed silent false-positive where check_tool_prefill
returned 0 even after fail() because rm -f cleanup clobbered $? — now
captures rc before cleanup and propagates.
CLIFFS.md: cross-reference Sandermage's broader 8-cliff catalog and add
"vLLM pin compatibility status" section documenting the v0.20 workspace-
lock regression (PR #39226) that blocks our config and is unrelated to
Cliff 1/2.
