## Overview

SPF Smart Gateway is a **Rust-based MCP (Model Context Protocol) server** that acts as a security gateway for AI tool calls. Every file operation, bash command, brain query, and mesh call routes through compiled Rust enforcement logic.

**No AI hallucination gets past the gate.**

### Web Agent Feature

SPF agents can directly interact with the web and social media platforms through `spf_web_api` — a full HTTP client supporting GET, POST, PUT, DELETE, PATCH with custom headers and JSON body. Tested and working.

**What agents can do:**
- Post to X/Twitter, Facebook, Instagram, Reddit via their APIs
- Reply to comments, send messages, manage accounts
- Make authenticated API calls to any platform with stored API keys
- Search, fetch, and download web content

All web API calls pass through the 6-step gate pipeline with rate limiting (30-120 calls/min), content inspection, and full audit logging. Agents never touch the open web unmonitored.

### Why Heed + LMDB

All persistent storage — config, agent state, brain vectors, session logs, gate training data — runs through **[heed](https://github.com/meilisearch/heed)**, a safe Rust wrapper over LMDB. This is what makes SPF extremely fast with a low memory footprint:

- **Zero-copy reads** — heed maps LMDB pages directly into memory, no serialization overhead
- **No server process** — LMDB is a memory-mapped B-tree library, not a database daemon
- **ACID transactions** — single-writer, multi-reader with no lock contention on reads
- **Sub-millisecond lookups** — B-tree index, not hash scanning
- **Tiny footprint** — entire 138K+ memory store runs in-process with minimal RAM
- **Phone-friendly** — designed for Android from day one; heed compiles cleanly on ARM64

Every tool call, brain search, and memory promotion goes through heed → LMDB. No network hops, no subprocess calls, no SQL parsing. The gate, brain, agent state, and FLINT training all share the same embedded database engine.

Two agent runtimes:
- **Flat files** — `LIVE/LMDB5/` (session state in markdown)
- **LMDB database** — `LIVE/LMDB5.DB/` (session state in LMDB for persistence)

Twin folder architecture: flat-file data uploaded via SPF CLI fs tools (user-only access). All agent tool calls are gated, validated, and audited.

## The SPF Formula

### Complexity Calculation

```
C = (basic ^ 1) + (dependencies ^ 7) + (complex ^ 10) + (files × 10)
```

### Dynamic Analysis Allocation

```
a_optimal(C) = W_eff × (1 - 1/ln(C + e))
```

Where `W_eff = 40,000` tokens and `e = Euler's number`

### Tier Allocation

| Tier | C Range | Analyze | Build | Verify Passes | Approval |
|------|---------|---------|-------|---------------|----------|
| SIMPLE | < 500 | 40% | 60% | 1 | No |
| LIGHT | < 2,000 | 60% | 40% | 1 | No |
| MEDIUM | < 10,000 | 75% | 25% | 2 | No |
| CRITICAL | > 10,000 | 95% | 5% | 3 | **Required** |

### Master Equation (Subtask Success)

```
P(success) = 1 - PRODUCT(1 - P_i)  for i=1..D subtasks
P_i = Q(a) × L(m) × V(v) × B(b)

Q(a) = 1 - e^(-0.00004 × a)   — Quality from analysis depth
L(m) = 1 - 0.20^(m/2000)       — Lookup from external memory
V(v) = 1 - (1 - 0.75)^v         — Verification accuracy
B(b) = checks_done / checks_required — Build Anchor compliance
```

---

## Security

### Gate Enforcement (6 Steps)

Every tool call passes through `gate::process()` — compiled Rust, no runtime bypass.

| Step | What | How |
|------|------|-----|
| 0 | Source logging | Identifies caller (Stdio, Transformer, Mesh, HTTP) |
| 1 | Rate limiting | Per-tool limits (30–120 calls/min) |
| 2 | Complexity calc | SPF formula → C value, tier, allocation |
| 3 | Validation | Per-tool validator (paths, commands, anchors) |
| 4 | Content inspection | Credential patterns, shell injection, path traversal |
| 5 | Max mode | Escalation to CRITICAL tier on warnings |

### Build Anchor Protocol

Files must be **read before they can be edited or overwritten**. Prevents AI hallucinations from blindly modifying files without understanding contents.

- `Read` tracks files in `session.files_read`
- `Edit` and `Write` check against this list
- `Bash` write-class commands check target file reads
- Violations: blocked (Max mode) or warned (Soft mode)

### Content Inspection

Scans written/stored content for:
- **Credential patterns**: API keys (sk-), AWS keys (AKIA), GitHub tokens (ghp_), Slack tokens, private keys, hardcoded passwords
- **Shell injection**: Command substitution `$()`, backticks, eval/exec
- **Path traversal**: `../` sequences
- **Blocked path references**: Content mentioning system paths

### Blocked Paths

Default blocked: `/tmp`, `/etc`, `/usr`, `/system`, `/data/data/com.termux/files/usr`

### Command Whitelist (Stage 0)

Bash commands checked against sandbox and user-filesystem whitelists. Each command segment validated independently. Destructive commands (rm, chmod 777) blocked even if whitelisted.

### Default Deny

Unknown tools blocked until explicitly added to the gate allowlist.

| Heads | 8 |
| Layers | 6 |
| Parameters | ~5M |
| Embeddings | all-MiniLM-L6-v2 (384d, in-process) |

     ↓                ↓                ↓
  Expire old       Top 20% promote    Never auto-expire
```

---

## Brain System

In-process vector memory using stoneshell-brain (Candle + LMDB + MiniLM-L6-v2).

|----------|-------|
| Model | all-MiniLM-L6-v2 |
| Embedding dim | 384 |
| Chunk size | 512 |
| Chunk overlap | 64 |
| Storage | LMDB (vectors) + LIVE/BRAIN/DOCS/ (data files) |

### Collections

### Memory Triad (Redundant Persistence)

Three systems — if any ONE fails, the other TWO recover:

1. **Brain** (vectors) — Semantic search, chunked knowledge
2. **STATUS** (sequential) — Current state, phase, next step
3. **Work Blocks** (structural) — Tasks, dependencies, confidence, progress
4. **Twin Folders** (evidence) — Data served for low-confidence work blocks

---

## Mesh Network

P2P agent communication over QUIC (iroh library) with Ed25519 identity. **In development and testing.**

| Feature | Status |
|---------|--------|
| P2P QUIC transport | In development |
| Ed25519 identity | In development |
| Peer discovery | In development |
| Tool call proxying | In development |
| Voice over mesh | In development |
| Chat over mesh | In development |
| Multi-agent coordination | In development |

---

## Voice Pipeline

**Not yet tested.** Components built, awaiting integration testing.

| Component | Technology |
|-----------|-----------|
| TTS | espeak-ng FFI (in-process) |
| Codec | Opus (libopus.a) |
| Audio | cpal + oboe-ext |
| STT | Pending (JNI via Stone Shell Terminal) |

---

## Result Compression (FL-2)

Three tiers based on result size:

| Tier | Size | Behavior |
|------|------|----------|
| FULL | < 500 chars | Pass through unchanged |
| SUMMARY | 500–5,000 | First 8 lines + last 3 lines + stats |
| DIGEST | > 5,000 | First 200 chars + last 100 chars + stats + recall hint |

Originals always preserved in brain (>2000 chars threshold) before compression. File reads never truncated (preserves non-Claude LLM compatibility).

---

## Build

```bash
cd SPFsmartGATE
cargo build --release

# Deploy binary
cp target/release/spf-smart-gate LIVE/BIN/spf-smart-gate/spf-smart-gate
```

### Dependencies

- Rust (stable)
- **[heed](https://github.com/meilisearch/heed)** — safe Rust LMDB bindings. All persistent storage (config, agent state, brain vectors, training data) runs through heed → LMDB. Zero-copy reads, no server process, sub-millisecond lookups. The core reason SPF runs fast on a phone.
- stoneshell-brain (Candle + MiniLM-L6-v2)
- espeak-ng (TTS)
- libopus (audio codec)
- iroh (QUIC mesh)

## Current Status

| Component | Status |
|-----------|--------|
| MCP Server | 81 gated tools |
| Gate Security | 6-step pipeline, compiled Rust enforcement |
| Build Anchor | Read-before-write enforced |
| Content Inspection | Credential + injection scanning |
| FLINT Transformer | ~5M params, online learning, gate-aligned |
| Brain | 7 collections, MiniLM-L6-v2, in-process |
| Memory Triad | Brain + STATUS + Work Blocks + Twin Folders |
| Tiered Promotion | Working → Fact → Pinned lifecycle |
| Mesh Network | P2P QUIC, Ed25519, iroh — **in development and testing** |
| Voice | TTS built (espeak-ng) — **not yet tested**, STT pending |
| Chat | P2P messaging over mesh — **in development** |
| RAG | Web search, RSS, file/folder indexing |
| Web Agent | **Working** — spf_web_api tested (GET/POST with auth headers). Agents can interact with social media APIs |
| Browser | API tools working (web_api, search, fetch). Browser automation (navigate/click/fill/select/eval) in development — proxy starts but WebSocket bridge needs browser connection |
| Network Pool | Worker pool with proof of work |

## Notes

- **1 developer** — not all features complete
- **Gateway security**: approaching 100%
- **All core tools**: 100% working
- **Cross-compiles** on Android and Linux with minimal installation
- **Agent cloning and specialization** supported
- **50+ day continuous session** tested on Android phone
- **Open source** — entire source code refreshes into transformer RAG system every reboot
- Install in home folder, ensure file paths are correct in `.mcp.json` and `settings.local.json`
- **Not all files have been uploaded yet** — repository is still being populated. Some modules may not be present until upload completes.
