- Dankclaw's charlie12345/ROCmFPX llama.cpp fork (build at ~/GitPackages/ROCmFPX/build-qwen38) shares the mainline --spec-type vocabulary plus draft-dspark; --spec-draft-n-max default is 16 there (mainline default 3). ngram-mod params on the fork: --spec-ngram-mod-n-min (default 48), --spec-ngram-mod-n-max (default 64), --spec-ngram-mod-n-match (default 24). Constraint in common/speculative.cpp: n_min is clamped to = n_max (std::max(0, std::min(n_min, n_max))) and n_max clamped to a server-side n_draft_max; NO constraint between n_match and n_min/n_max — n_match (lookup window) is independent of draft token count. Use these when building the ngram-mod pyramid sweep for frank-llm-bench. _(context: frank-llm-bench project; Dankclaw ROCmFPX fork at ~/GitPackages/ROCmFPX/build-qwen38)_
- llama.cpp (mainline, verified 2026-08) spec-decoding flags: --spec-type takes a comma-separated list: none, draft-simple, draft-eagle3, draft-mtp, draft-dflash, ngram-simple, ngram-map-k, ngram-map-k4v, ngram-mod, ngram-cache. Multiple speculators stack via comma (e.g. "draft-mtp,ngram-mod"). n-max-spec maps to TWO different flags: --spec-draft-n-max N (default 3) controls draft-model token count; --spec-ngram-mod-n-max N controls ngram-mod token count. For stacked configs, set both to the same N. MTP capability is detected from GGUF metadata key {arch}.nextn_predict_layers (0 means model has embedded MTP head). --spec-type draft-mtp requires an MTP-capable GGUF; it does not add MTP at runtime. ROCmFPX fork (charlie12345) may use different flag names at its llama.cpp base point — verify fork's --help on Dankclaw before relying on these. _(context: Grilling session for frank-llm-bench; flags confirmed from local ~/GitPackages/llama.cpp/build/bin/llama-server --help.)_
- Frank's three machines: (1) Dankware — dev laptop, Intel Core Ultra 7 155H, Arc iGPU + RTX 4070 Max-Q Mobile (discrete, non-unified memory), 62GB RAM, 22 threads. NEVER runs inference / never a bench target. llama.cpp mainline built at ~/GitPackages/llama.cpp/build/bin/. (2) Dankserver — currently runs FreeToken (not llama.cpp). (3) Dankclaw — Strix Halo AMD APU, single unified GPU memory pool → hits the n-cpu-moe [REDACTED] (non-unified-memory check fails). Runs charlie12345/ROCmFPX llama.cpp fork. Service frank-default-large, port 7770, health http://192.168.0.143:7770/health. Model: kingjones Qwen3.8-Flash-Next ROCmFP4 STRIX_LEAN, 56B MoE (512 experts, 10 used), ~98GB, Q4_0_ROCMFP4. Text-only — NO embedded MTP draft head (confirmed in serverAppConfigs scripts/frank-default-large.env).

- Frank prefers merge (not rebase) for resolving branch drift before PRs. He dislikes the historical revision that comes with excessive rebasing. When updating a feature branch against a moved main, merge main into the branch rather than rebasing the branch onto main. This applies to all git workflows on his repos unless he says otherwise. _(context: Grilling session for frank-llm-bench project init; Q2 drift rule.)_
