ad70b3439c feat(llm): add nomic-embed-text-v1.5-Q4_K_M to astro-orbiter router 
OpenViking Phase 1b (t_34b96e83) — Ryan-approved implementation.

Changes:
- roles/llm-inference-multimodel/templates/llama-server-router-preset.ini.j2:
  Add [nomic-embed-text-v1.5] section with embedding=true, n-gpu-layers=99,
  ctx-size=8192, load-on-startup=true, sleep-idle-seconds=-1. No flash-attn
  or KV cache params (embedding models use bidirectional forward pass, not
  autoregressive KV cache). Var: llm_router_nomic_ctx_size.

- roles/llm-inference-multimodel/defaults/main.yml:
  Add llm_router_nomic_ctx_size: 8192.

- host_vars/astro-orbiter/vars.yml:
  Add nomic-embed-text-v1.5-Q4_K_M.gguf to llm_staged_models list
  (size_bytes: 84106624, source: nomic-ai/nomic-embed-text-v1.5-GGUF).
  Update VRAM note to reflect 5 registered models (nomic adds ~84MB,
  negligible given sleep-idle-seconds=-1 / load-on-startup=true pinning).

- playbooks/day2_add_nomic_embed.yml:
  New day2 playbook following the coder-alias pattern:
  Phase 1: idempotent GGUF download (exact size check)
  Phase 2: redeploy preset INI
  Phase 3: redeploy + restart systemd unit
  Phase 4: /v1/models gate (all 5 models present)
  Phase 5: /v1/embeddings smoke test (vector returned, not empty)

VRAM: ~84MB, always pinned. No impact on generative model LRU behavior.
peter-parker Helm values already point at :8002 for the embedding endpoint.

7aea88724f Add Qwen2.5-Coder-14B-Instruct-4bit to astro-orbiter router (t_55c164f5) 
- host_vars/astro-orbiter/vars.yml: add Qwen2.5-Coder-14B-Instruct-Q4_K_M.gguf
  to llm_staged_models (size_bytes=8988111072, bartowski GGUF public repo).
  Updated VRAM note to reflect 4-model roster and LRU eviction semantics.
- defaults/main.yml: add llm_router_coder_ctx_size=16384 and
  llm_router_coder_flash_attn=true variables for per-model ctx tuning.
- templates/llama-server-router-preset.ini.j2: add [Qwen2.5-Coder-14B-Instruct-Q4_K_M]
  section with alias=Qwen2.5-Coder-14B-Instruct-4bit, ctx-size=16384, flash-attn=true.
- playbooks/day2_add_coder_alias.yml: new playbook that downloads the GGUF (if
  absent/mismatched), deploys updated preset INI and systemd unit, restarts
  llama-server-router, and verifies all 4 models in /v1/models.

VRAM: Coder ~9GB. Full 4-model co-residency impossible on 24GB — LRU eviction
handles this automatically. Qwen3.6-35B <-> Coder switches incur ~30-60s cold load.

6455d22752 feat(llm-router): add Meta-Llama-3.1-8B-Instruct-4bit alias; document Phi json_schema limitation (t_9adf0889) 
- Add Meta-Llama-3.1-8B-Instruct-4bit alias on Meta-Llama-3.1-8B-Instruct-Q4_K_M
  entry in the preset INI (per Ryan dashboard note).
- Document known issue: Phi-3.5-mini json_schema grammar sampler incompatibility
  in router mode (GH #23460 variant — chat template token format mismatch).
  Meta-Llama works with json_schema response_format; confirmed via live test.
- Phi-3.5-mini-instruct-8bit alias remains working for model routing;
  structured output (json_schema) fails due to the model's token format.

a47b29d49f feat(llm-router): switch to --models-preset mode; add Phi-3.5-mini-instruct-8bit alias (t_9adf0889) 
- Add templates/llama-server-router-preset.ini.j2: defines all 3 router GGUFs
  (Qwen3.6-35B, Phi-3.5-mini-Q8_0, Meta-Llama-3.1-8B) with explicit ctx-size,
  gpu-layers, cache settings carried over from --models-dir baseline. The Phi
  entry adds alias=Phi-3.5-mini-instruct-8bit (Ryan's aux.title_generation target).

- Update templates/llama-server-router.service.j2: Jinja2 conditional emits
  --models-preset <path> when llm_router_preset_enabled=true, otherwise
  --models-dir (backward compat, default unchanged).

- Add tasks/preset.yml: deploy preset INI, restart router on change, verify
  both Phi-3.5-mini-instruct-Q8_0 (primary) and Phi-3.5-mini-instruct-8bit
  (alias) appear in /v1/models, plus Qwen and Llama IDs unchanged.

- Update defaults/main.yml: add llm_router_preset_enabled (default false) and
  llm_router_preset_path=/opt/llama-server-router-preset.ini.

- Update tasks/main.yml: import preset.yml as Phase P (gated, no-op by default).
- Update handlers/main.yml: add 'restart router' handler for preset changes.
- Add playbooks/day2_add_phi_alias.yml: single-command deployment.

GH #22364 note: --models-preset mode creates an extra 'default' entry in
/v1/models — cosmetic, does not affect model selection by name.
