Ruflo 3.6.27 — Ollama provider (Tier-2) closes #1725

Single-issue release closing #1725. Validated end-to-end against ruvultra running ollama on a Tailscale tailnet.

What's new

Ollama is now a first-class provider — Tier-2 in the 3-tier model routing per ADR-026. End users on Anthropic Max plans (which don't expose `ANTHROPIC_API_KEY`) plus Ollama Cloud subscribers can finally use `workflow_execute` and any other agent path that routes through `callAnthropicMessages`.

Configure

# Ollama Cloud
ruflo providers configure -p ollama -k \$OLLAMA_API_KEY
ruflo providers test -p ollama   # round-trips the key

# Self-hosted Ollama (this release validated against ruvultra over Tailscale)
export OLLAMA_API_KEY=local                              # sentinel — skip auth header
export OLLAMA_BASE_URL=http://ruvultra:11434             # any Ollama endpoint
export RUFLO_PROVIDER=ollama                             # or unset ANTHROPIC_API_KEY

Provider selection logic

`callAnthropicMessages` now picks Ollama when:

1. `RUFLO_PROVIDER=ollama` (explicit), OR
2. `ANTHROPIC_API_KEY` unset AND `OLLAMA_API_KEY` set (auto-fallback)

Falls back to Anthropic when the env is right for it. Response shape is normalized to `AnthropicCallResult` either way — callers see `{ success, model, output, usage, durationMs }` regardless of provider.

Validation against ruvultra (Tailscale)

• Installed ollama 0.23.0 on ruvultra (Ubuntu 24.04)
• Daemon bound to `0.0.0.0:11434`
• Pulled `llama3.2:1b`
• From local Mac, called `callAnthropicMessages` over Tailscale → 611ms round-trip, 49 tokens
• Response normalized correctly

Known gap (upstream)

`agentic-flow config-wizard` still hardcodes 4 providers (anthropic / openrouter / gemini / onnx). That's an upstream wedge in the `agentic-flow` npm package — out of scope for this repo. Workaround: set `OLLAMA_API_KEY` directly in the environment (not via `agentic-flow config set`); ruflo's runtime picks it up regardless of what the wizard thinks.
