Avoid fact gathering for Windows Ollama playbook

- Prole registered as tenant_id=1, uuid=000necda5b3a6tc2 (DNS anchor)
- Project embedding store uuid=000nectf23m7865j (tenant_id=1 in bits)
- Schema p_000nectf23m7865j: chunks, embeddings, embeddings_merged (vector 1024)
- HNSW index on embeddings_merged for cosine similarity search
- Cross-grant issued to tenant 0 (knoe.dev MCP): grant id=000neddhjsr8eadg
- Establishes knoe-db/schema/migrations/ directory (sqitch wiring: tomorrow)

+# windows_ollama_models.yml — Manage local Ollama model variants on Windows GPU hosts.
+#
+# This is the small, Ansible-like control surface for the two Windows NVIDIA
+# machines that run Ollama for Prole embedding workloads.
+#
+# Usage:
+#   cd infrastructure
+#   ansible-playbook playbooks/windows_ollama_models.yml --ask-pass
+#
+# Single host:
+#   ansible-playbook playbooks/windows_ollama_models.yml --limit morgoth.prole.org --ask-pass
+#
+# Dry-run intent only:
+#   ansible-playbook playbooks/windows_ollama_models.yml --check --diff --ask-pass
+#
+# Inventory target:
+#   [workstations_windows]
+#   morgoth.prole.org
+#   fairyland.prole.org
+#
+# What this deploys:
+#   ollama create mxbai-embed-large-2k FROM mxbai-embed-large PARAMETER num_ctx 2048
+#
+# The desired Modelfile is written to C:\ProgramData\Prole\Ollama\Models and a
+# SHA-256 marker is recorded after successful creation. Re-running the playbook
+# is safe: it recreates the model only when the target model is missing or the
+# managed Modelfile content changes.
