feat: add vLLM as alternative inference backend (#1281)

Adds vLLM (high-throughput OpenAI-compatible inference server) as a
selectable backend alongside the existing Ollama and vllm-mlx backends.
vLLM's continuous batching gives 3-10x throughput for agentic workloads.

Changes:
- config.py: add `vllm` to timmy_model_backend Literal; add vllm_url /
  vllm_model settings (VLLM_URL / VLLM_MODEL env vars)
- cascade.py: add vllm provider type with _check_provider_available
  (hits /health) and _call_vllm (OpenAI-compatible completions)
- providers.yaml: add disabled-by-default vllm-local provider (priority 3,
  port 8001); bump OpenAI/Anthropic backup priorities to 4/5
- health.py: add _check_vllm/_check_vllm_sync with 30-second TTL cache;
  /health and /health/sovereignty reflect vLLM status when it is the
  active backend
- docker-compose.yml: add vllm service behind 'vllm' profile (GPU
  passthrough commented-out template included); add vllm-cache volume
- CLAUDE.md: add vLLM row to Service Fallback Matrix
- tests: 26 new unit tests covering availability checks, _call_vllm,
  providers.yaml validation, config options, and health helpers

Graceful fallback: if vLLM is unavailable the cascade router automatically
falls back to Ollama. The app never crashes.

Fixes #1281

-## Tickets Created
-
-### #1281 — feat: add vLLM as alternative inference backend
-**Source:** IMG_6125 (vLLM for agentic workloads)
-
-vLLM's continuous batching makes it 3–10x more throughput-efficient than Ollama for multi-agent
-request patterns. Implement `VllmBackend` in `infrastructure/llm_router/` as a selectable
-backend (`TIMMY_LLM_BACKEND=vllm`) with graceful fallback to Ollama.
-
-**Priority:** Medium — impactful for research pipeline performance once #972 is in use
-
----
-
-### #1282 — feat: integrate SearXNG + Crawl4AI as self-hosted search backend
-**Source:** IMG_6410 (luxiaolei/searxng-crawl4ai-mcp)
-
-Self-hosted search via SearXNG + Crawl4AI removes the hard dependency on paid search APIs
-(Brave, Tavily). Add both as Docker Compose services, implement `web_search()` and
-`scrape_url()` tools in `timmy/tools/`, and register them with the research agent.
-
-**Priority:** High — unblocks fully local/private operation of research agents
-
----
-
-### #1283 — research: evaluate DeerFlow as autonomous research orchestration layer
-**Source:** IMG_6124 (deer-flow Docker setup)
-
-DeerFlow is ByteDance's open-source autonomous research pipeline framework. Before investing
-further in Timmy's custom orchestrator (#972), evaluate whether DeerFlow's architecture offers
-integration value or design patterns worth borrowing.
-
-**Priority:** Medium — research first, implementation follows if go/no-go is positive
-
----
-
-### #1284 — chore: document and validate AirLLM Apple Silicon requirements
-**Source:** IMG_6187 (Mac-compatible LLM setup)
-
-AirLLM graceful degradation is already implemented but undocumented. Add System Requirements
-to README (M1/M2/M3/M4, 16 GB RAM min, 15 GB disk) and document `TIMMY_LLM_BACKEND` in
-`.env.example`.
-
-**Priority:** Low — documentation only, no code risk
-
----
-
-### #1285 — chore: enforce "Normal Developer" discipline — tighten quality gates
-**Source:** IMG_6123 (Vibe Coder vs Normal Developer meme)
-
-Tighten the existing mypy/bandit/coverage gates: fix all mypy errors, raise coverage from 73%
-to 80%, add a documented pre-push hook, and run `vulture` for dead code. The infrastructure
-exists — it just needs enforcing.
-
-**Priority:** Medium — technical debt prevention, pairs well with any green-field feature work
-
----
-
-## Patterns Observed Across Screenshots
-
-1. **Local-first is the north star.** All five images reinforce the same theme: private,
-   self-hosted, runs on your hardware. vLLM, SearXNG, AirLLM, DeerFlow — none require cloud.
-   Timmy is already aligned with this direction; these are tactical additions.
-
-2. **Agentic performance bottlenecks are real.** Two of five images (vLLM, DeerFlow) focus
-   specifically on throughput and reliability for multi-agent loops. As the research pipeline
-   matures, inference speed and search reliability will become the main constraints.
-
-3. **Discipline compounds.** The meme is a reminder that the quality gates we have (tox,
-   mypy, bandit, coverage) only pay off if they are enforced without exceptions.

-## Executive Summary
-
-The blueprint establishes that a sovereign creative AI capable of coding, composing music,
-generating art, building worlds, publishing narratives, and managing its own economy is
-**technically feasible today** — but only through orchestration of dozens of tools operating
-at different maturity levels. The core insight: *the integration is the invention*. No single
-component is new; the missing piece is a coherent identity operating across all domains
-simultaneously with persistent memory, autonomous economics, and cross-domain creative
-reactions.
-
-Three non-negotiable architectural decisions:
-1. **Human oversight for all public-facing content** — every successful creative AI has this;
-   every one that removed it failed.
-2. **Legal entity before economic activity** — AI agents are not legal persons; establish
-   structure before wealth accumulates (Truth Terminal cautionary tale: $20M acquired before
-   a foundation was retroactively created).
-3. **Hybrid memory: vector search + knowledge graph** — neither alone is sufficient for
-   multi-domain context breadth.

-## Domain-by-Domain Assessment
-
-### Software Development (immediately deployable)
-
-| Component | Recommendation | Notes |
-|-----------|----------------|-------|
-| Primary agent | Claude Code (Opus 4.6, 77.2% SWE-bench) | Already in use |
-| Self-hosted forge | Forgejo (MIT, 170–200MB RAM) | Project uses Gitea/Forgejo now |
-| CI/CD | GitHub Actions-compatible via `act_runner` | — |
-| Tool-making | LATM pattern: frontier model creates tools, cheaper model applies them | New — see ADR opportunity |
-| Open-source fallback | OpenHands (~65% SWE-bench, Docker sandboxed) | Backup to Claude Code |
-| Self-improvement | Darwin Gödel Machine / SICA patterns | 3–6 month investment |
-
-**Development estimate:** 2–3 weeks for Forgejo + Claude Code integration with automated
-PR workflows; 1–2 months for self-improving tool-making pipeline.
-
-**Cross-reference:** This project already runs Claude Code agents on Forgejo. The LATM
-pattern (tool registry) and self-improvement loop are the actionable gaps.
-
----
-
-### Music (1–4 weeks)
-
-| Component | Recommendation | Notes |
-|-----------|----------------|-------|
-| Commercial vocals | Suno v5 API (~$0.03/song, $30/month Premier) | No official API; third-party: sunoapi.org, AIMLAPI, EvoLink |
-| Local instrumental | MusicGen 1.5B (CC-BY-NC — monetization blocker) | On M2 Max: ~60s for 5s clip |
-| Voice cloning | GPT-SoVITS v4 (MIT) | Works on Apple Silicon CPU, RTF 0.526 on M4 |
-| Voice conversion | RVC (MIT, 5–10 min training audio) | — |
-| Apple Silicon TTS | MLX-Audio: Kokoro 82M + Qwen3-TTS 0.6B | 4–5x faster via Metal |
-| Publishing | Wavlake (90/10 split, Lightning micropayments) | Auto-syndicates to Fountain.fm |
-| Nostr | NIP-94 (kind:1063) audio events → NIP-96 servers | — |
-
-**Copyright reality:** US Copyright Office (Jan 2025) and US Court of Appeals (Mar 2025):
-purely AI-generated music cannot be copyrighted and enters public domain. Wavlake's
-Value4Value model works around this — fans pay for relationship, not exclusive rights.
-
-**Avoid:** Udio (download disabled since Oct 2025, 2.4/5 Trustpilot).
-
----
-
-### Visual Art (1–3 weeks)
-
-| Component | Recommendation | Notes |
-|-----------|----------------|-------|
-| Local generation | ComfyUI API at `127.0.0.1:8188` (programmatic control via WebSocket) | MLX extension: 50–70% faster |
-| Speed | Draw Things (free, Mac App Store) | 3× faster than ComfyUI via Metal shaders |
-| Quality frontier | Flux 2 (Nov 2025, 4MP, multi-reference) | SDXL needs 16GB+, Flux Dev 32GB+ |
-| Character consistency | LoRA training (30 min, 15–30 references) + Flux.1 Kontext | Solved problem |
-| Face consistency | IP-Adapter + FaceID (ComfyUI-IP-Adapter-Plus) | Training-free |
-| Comics | Jenova AI ($20/month, 200+ page consistency) or LlamaGen AI (free) | — |
-| Publishing | Blossom protocol (SHA-256 addressed, kind:10063) + Nostr NIP-94 | — |
-| Physical | Printful REST API (200+ products, automated fulfillment) | — |
-
----
-
-### Writing / Narrative (1–4 weeks for pipeline; ongoing for quality)
-
-| Component | Recommendation | Notes |
-|-----------|----------------|-------|
-| LLM | Claude Opus 4.5/4.6 (leads Mazur Writing Benchmark at 8.561) | Already in use |
-| Context | 500K tokens (1M in beta) — entire novels fit | — |
-| Architecture | Outline-first → RAG lore bible → chapter-by-chapter generation | Without outline: novels meander |
-| Lore management | WorldAnvil Pro or custom LoreScribe (local RAG) | No tool achieves 100% consistency |
-| Publishing (ebooks) | Pandoc → EPUB / KDP PDF | pandoc-novel template on GitHub |
-| Publishing (print) | Lulu Press REST API (80% profit, global print network) | KDP: no official API, 3-book/day limit |
-| Publishing (Nostr) | NIP-23 kind:30023 long-form events | Habla.news, YakiHonne, Stacker News |
-| Podcasts | LLM script → TTS (ElevenLabs or local Kokoro/MLX-Audio) → feedgen RSS → Fountain.fm | Value4Value sats-per-minute |
-
-**Key constraint:** AI-assisted (human directs, AI drafts) = 40% faster. Fully autonomous
-without editing = "generic, soulless prose" and character drift by chapter 3 without explicit
-memory.
-
----
-
-### World Building / Games (2 weeks–3 months depending on target)
-
-| Component | Recommendation | Notes |
-|-----------|----------------|-------|
-| Algorithms | Wave Function Collapse, Perlin noise (FastNoiseLite in Godot 4), L-systems | All mature |
-| Platform | Godot Engine + gd-agentic-skills (82+ skills, 26 genre blueprints) | Strong LLM/GDScript knowledge |
-| Narrative design | Knowledge graph (world state) + LLM + quest template grammar | CHI 2023 validated |
-| Quick win | Luanti/Minetest (Lua API, 2,800+ open mods for reference) | Immediately feasible |
-| Medium effort | OpenMW content creation (omwaddon format engineering required) | 2–3 months |
-| Future | Unity MCP (AI direct Unity Editor interaction) | Early-stage |
-
----
-
-### Identity Architecture (2 months)
-
-The blueprint formalizes the **SOUL.md standard** (GitHub: aaronjmars/soul.md):
-
-| File | Purpose |
-|------|---------|
-| `SOUL.md` | Who you are — identity, worldview, opinions |
-| `STYLE.md` | How you write — voice, syntax, patterns |
-| `SKILL.md` | Operating modes |
-| `MEMORY.md` | Session continuity |
-
-**Critical decision — static vs self-modifying identity:**
-- Static Core Truths (version-controlled, human-approved changes only) ✓
-- Self-modifying Learned Preferences (logged with rollback, monitored by guardian) ✓
-- **Warning:** OpenClaw's "Soul Evolution" creates a security attack surface — Zenity Labs
-  demonstrated a complete zero-click attack chain targeting SOUL.md files.
-
-**Relevance to this repo:** Claude Code agents already use a `MEMORY.md` pattern in
-this project. The SOUL.md stack is a natural extension.
-
----
-
-### Memory Architecture (2 months)
-
-Hybrid vector + knowledge graph is the recommendation:
-
-| Component | Tool | Notes |
-|-----------|------|-------|
-| Vector + KG combined | Mem0 (mem0.ai) | 26% accuracy improvement over OpenAI memory, 91% lower p95 latency, 90% token savings |
-| Vector store | Qdrant (Rust, open-source) | High-throughput with metadata filtering |
-| Temporal KG | Neo4j + Graphiti (Zep AI) | P95 retrieval: 300ms, hybrid semantic + BM25 + graph |
-| Backup/migration | AgentKeeper (95% critical fact recovery across model migrations) | — |
-
-**Journal pattern (Stanford Generative Agents):** Agent writes about experiences, generates
-high-level reflections 2–3x/day when importance scores exceed threshold. Ablation studies:
-removing any component (observation, planning, reflection) significantly reduces behavioral
-believability.
-
-**Cross-reference:** The existing `brain/` package is the memory system. Qdrant and
-Mem0 are the recommended upgrade targets.
-
----
-
-### Multi-Agent Sub-System (3–6 months)
-
-The blueprint describes a named sub-agent hierarchy:
-
-| Agent | Role |
-|-------|------|
-| Oracle | Top-level planner / supervisor |
-| Sentinel | Safety / moderation |
-| Scout | Research / information gathering |
-| Scribe | Writing / narrative |
-| Ledger | Economic management |
-| Weaver | Visual art generation |
-| Composer | Music generation |
-| Social | Platform publishing |
-
-**Orchestration options:**
-- **Agno** (already in use) — microsecond instantiation, 50× less memory than LangGraph
-- **CrewAI Flows** — event-driven with fine-grained control
-- **LangGraph** — DAG-based with stateful workflows and time-travel debugging
-
-**Scheduling pattern (Stanford Generative Agents):** Top-down recursive daily → hourly →
-5-minute planning. Event interrupts for reactive tasks. Re-planning triggers when accumulated
-importance scores exceed threshold.
-
-**Cross-reference:** The existing `spark/` package (event capture, advisory engine) aligns
-with this architecture. `infrastructure/event_bus` is the choreography backbone.
-
----
-
-### Economic Engine (1–4 weeks)
-
-Lightning Labs released `lightning-agent-tools` (open-source) in February 2026:
-- `lnget` — CLI HTTP client for L402 payments
-- Remote signer architecture (private keys on separate machine from agent)
-- Scoped macaroon credentials (pay-only, invoice-only, read-only roles)
-- **Aperture** — converts any API to pay-per-use via L402 (HTTP 402)
-
-| Option | Effort | Notes |
-|--------|--------|-------|
-| ln.bot | 1 week | "Bitcoin for AI Agents" — 3 commands create a wallet; CLI + MCP + REST |
-| LND via gRPC | 2–3 weeks | Full programmatic node management for production |
-| Coinbase Agentic Wallets | — | Fiat-adjacent; less aligned with sovereignty ethos |
-
-**Revenue channels:** Wavlake (music, 90/10 Lightning), Nostr zaps (articles), Stacker News
-(earn sats from engagement), Printful (physical goods), L402-gated API access (pay-per-use
-services), Geyser.fund (Lightning crowdfunding, better initial runway than micropayments).
-
-**Cross-reference:** The existing `lightning/` package in this repo is the foundation.
-L402 paywall endpoints for Timmy's own services is the actionable gap.
-
----
-
-## Pioneer Case Studies
-
-| Agent | Active | Revenue | Key Lesson |
-|-------|--------|---------|-----------|
-| Botto | Since Oct 2021 | $5M+ (art auctions) | Community governance via DAO sustains engagement; "taste model" (humans guide, not direct) preserves autonomous authorship |
-| Neuro-sama | Since Dec 2022 | $400K+/month (subscriptions) | 3+ years of iteration; errors became entertainment features; 24/7 capability is an insurmountable advantage |
-| Truth Terminal | Since Jun 2024 | $20M accumulated | Memetic fitness > planned monetization; human gatekeeper approved tweets while selecting AI-intent responses; **establish legal entity first** |
-| Holly+ | Since 2021 | Conceptual | DAO of stewards for voice governance; "identity play" as alternative to defensive IP |
-| AI Sponge | 2023 | Banned | Unmoderated content → TOS violations + copyright |
-| Nothing Forever | 2022–present | 8 viewers | Unmoderated content → ban → audience collapse; novelty-only propositions fail |
-
-**Universal pattern:** Human oversight + economic incentive alignment + multi-year personality
-development + platform-native economics = success.
-

-
-## Recommended Implementation Sequence
-
-From the blueprint, mapped against Timmy's existing architecture:
-
-### Phase 1: Immediate (weeks)
-1. **Code sovereignty** — Forgejo + Claude Code automated PR workflows (already substantially done)
-2. **Music pipeline** — Suno API → Wavlake/Nostr NIP-94 publishing
-3. **Visual art pipeline** — ComfyUI API → Blossom/Nostr with LoRA character consistency
-4. **Basic Lightning wallet** — ln.bot integration for receiving micropayments
-5. **Long-form publishing** — Nostr NIP-23 + RSS feed generation
-
-### Phase 2: Moderate effort (1–3 months)
-6. **LATM tool registry** — frontier model creates Python utilities, caches them, lighter model applies
-7. **Event-driven cross-domain reactions** — game event → blog + artwork + music (CrewAI/LangGraph)
-8. **Podcast generation** — TTS + feedgen → Fountain.fm
-9. **Self-improving pipeline** — agent creates, tests, caches own Python utilities
-10. **Comic generation** — character-consistent panels with Jenova AI or local LoRA
-
-### Phase 3: Significant investment (3–6 months)
-11. **Full sub-agent hierarchy** — Oracle/Sentinel/Scout/Scribe/Ledger/Weaver with Agno
-12. **SOUL.md identity system** — bounded evolution + guardian monitoring
-13. **Hybrid memory upgrade** — Qdrant + Mem0/Graphiti replacing or extending `brain/`
-14. **Procedural world generation** — Godot + AI-driven narrative (quests, NPCs, lore)
-15. **Self-sustaining economic loop** — earned revenue covers compute costs

-### Remains aspirational (12+ months)
-- Fully autonomous novel-length fiction without editorial intervention
-- YouTube monetization for AI-generated content (tightening platform policies)
-- Copyright protection for AI-generated works (current US law denies this)
-- True artistic identity evolution (genuine creative voice vs pattern remixing)
-- Self-modifying architecture without regression or identity drift

-## Gap Analysis: Blueprint vs Current Codebase
-
-| Blueprint Capability | Current Status | Gap |
-|---------------------|----------------|-----|
-| Code sovereignty | Done (Claude Code + Forgejo) | LATM tool registry |
-| Music generation | Not started | Suno API integration + Wavlake publishing |
-| Visual art | Not started | ComfyUI API client + Blossom publishing |
-| Writing/publishing | Not started | Nostr NIP-23 + Pandoc pipeline |
-| World building | Bannerlord work (different scope) | Luanti mods as quick win |
-| Identity (SOUL.md) | Partial (CLAUDE.md + MEMORY.md) | Full SOUL.md stack |
-| Memory (hybrid) | `brain/` package (SQLite-based) | Qdrant + knowledge graph |
-| Multi-agent | Agno in use | Named hierarchy + event choreography |
-| Lightning payments | `lightning/` package | ln.bot wallet + L402 endpoints |
-| Nostr identity | Referenced in roadmap, not built | NIP-05, NIP-89 capability cards |
-| Legal entity | Unknown | **Must be resolved before economic activity** |

-## ADR Candidates
-
-Issues that warrant Architecture Decision Records based on this review:
-
-1. **LATM tool registry pattern** — How Timmy creates, tests, and caches self-made tools
-2. **Music generation strategy** — Suno (cloud, commercial quality) vs MusicGen (local, CC-BY-NC)
-3. **Memory upgrade path** — When/how to migrate `brain/` from SQLite to Qdrant + KG
-4. **SOUL.md adoption** — Extending existing CLAUDE.md/MEMORY.md to full SOUL.md stack
-5. **Lightning L402 strategy** — Which services Timmy gates behind micropayments
-6. **Sub-agent naming and contracts** — Formalizing Oracle/Sentinel/Scout/Scribe/Ledger/Weaver
