Model swap: gemma4:9b has no official checkpoint; LAN server (192.168.0.47:11434) ships gemma4:26b (25.8B Q4_K_M), which fits the §6.5 26B cap and the "high-quality" tier. Updates §1.1, §2.1 diagram, §3.1 ai_provider example, §4.1 provider name, §4.2 request body, §4.6 health check, §5.4 copy catalog, plan Task 12 (mock + default model), Task 30 main entry, Task 33 dogfood intro. Endpoint: LocalOllamaProvider now configurable via constructor opts. Task 30 main entry and integration test read INKLING_OLLAMA_ENDPOINT from env; unset falls back to localhost. LAN Ollama moves from out-of-scope to in-scope via endpoint injection; only a separate LanOllamaProvider class remains deferred. Perf target §6.4: RTX 3060-referenced <30s target no longer valid under 26B Q4_K_M + LAN. Set to <60s provisional; §8 adds a new open issue to measure real p95 during first dogfood week and confirm. §7.4 adds INKLING_OLLAMA_ENDPOINT env setup and recommends Volta over nvm-windows for Windows Node 24.15.0 install.
