Measured 2026-10-04 18:46:07 PDT (live podman logs): 48 gdn_hip state faults in one 0.6 s burst — 'state out of ssm-cache range: max|S|=0 with non-finite values (slot=42 head=3|8)', one per TP rank, 23 GDN layers each — then the process-lifetime report cap. The guard's own text in this build names it: 'known Qwen3.8-Flash-Next (QFN) flaw under prefix caching … Mitigation: --no-enable-prefix-caching'. Mechanism: prefix caching puts QFN on mamba_cache_mode 'align', which checkpoints each sequence's GDN recurrent state into a mamba page per 3136-token block and re-seeds it from that page when a request resumes from a cached prefix. The NaN state landed at the 13th boundary (13 x 3136 = 40,768 — the reported ~40k mark) and persisted in the page: every later turn of that conversation re-seeded the same non-finite state for two heads, silently (fault-report cap already spent). RAM ruled out the same day: zero MCE/EDAC records since the boot under test, 8 GiB in-band pattern stable under live load, 4800 MT/s is the JEDEC floor on 5600-rated DIMMs, and the two-head single-slot NaN signature is a state-path fault, not scattered bit corruption. Fix: FRANK_PRIMARY_NO_PREFIX_CACHING=1 -> --no-enable-prefix-caching (flag renders in both directions from the knob). Cost: every turn re-prefills the whole history instead of at most 3135 tail tokens. Seam updated: the prefix-cache pin now asserts the conditional render and the shipped OFF value. Runbook carries the evidence + acceptance criteria; all 368 tests pass.
Server App Configs
The single repository for the two homelab servers: the Podman container stacks and the LLM inference fleet. One repo, one checkout per host, one deploy script.
2026-08-22: the former
vllmScriptsrepository (LLM fleet) is merged into this repo with its full git history. See AGENTS.md for the merge note.

Deployment
See serverAppConfigs-docs/Architecture/Deployment Flow.md
and serverAppConfigs-docs/LLM/deployment.md. Run
./scripts/deploy.sh <dankclaw|dankserver> after committing changes. It
plans and deploys only the changed services. Use --service NAME for an
explicit single-service retry; inference is restarted only when its own files
(or the shared chat template) changed.
Knowledge Base
The serverAppConfigs-docs/ directory is an Obsidian vault. Start at
serverAppConfigs-docs/index.md. The LLM fleet knowledge base lives at
serverAppConfigs-docs/LLM/index.md.
Testing
Run ./tests/run.sh before every push. See
serverAppConfigs-docs/Architecture/Testing Policy.md.
