# BlackRoad Governance Layer — Roadmap v0

> **Status:** Planning
> **Owner:** Cece (`cece.governor.v1`)
> **Last Updated:** 2025-11-30

---

## Overview

This document defines the governance infrastructure for BlackRoad OS — the protocol layer that makes agent operations **auditable, policy-compliant, and explainable**.

### Core Objects

| Object | Purpose |
|--------|---------|
| **POLICY** | Rules that allow, deny, or modify actions |
| **LEDGER** | Immutable audit trail of all governance events |
| **AGENT** | Registry of workers and their capabilities |
| **INTENT** | Tasks, goals, and workflow state |
| **CLAIM** | Assertions about identity and roles |
| **DELEGATION** | Scoped permissions from delegator → delegate |

### Causal Chain

```
INTENT → AGENT → TOOL CALL → POLICY CHECK → LEDGER EVENT
```

Every significant action flows through this chain, producing an audit trail.

## KV Schema

### Design Principles

1. **Keys are human-readable** — debugging at 2am shouldn't require a decoder ring
2. **Values are JSON** — structured, versionable, extensible
3. **Prefixes define namespace** — `policy:`, `ledger:`, `agent:`, `intent:`, `claim:`, `delegation:`
4. **Timestamps are ISO 8601** — always UTC
5. **IDs use format `{type}-{YYYYMMDD}-{short-hash}`** — sortable, unique, traceable

### Key Patterns

| Namespace | Key Pattern | Example |
|-----------|-------------|---------|
| POLICY | `policy:{scope}:{policy_id}` | `policy:email.send:pol-20251130-a1b2c3` |
| LEDGER | `ledger:{intent_id}:{event_id}` | `ledger:int-20251130-x1y2z3:evt-20251130-000001` |
| AGENT | `agent:{agent_id}` | `agent:cece.governor.v1` |
| INTENT | `intent:{intent_id}` | `intent:int-20251130-x1y2z3` |
| CLAIM | `claim:{subject}:{claim_id}` | `claim:user:alexa:clm-20251130-own001` |
| DELEGATION | `delegation:{delegator}:{delegation_id}` | `delegation:user:alexa:del-20251130-d001` |

### Index Keys

| Query | Index Key |
|-------|-----------|
| All active policies | `policy:active` |
| Policies for scope | `policy:scope:{scope}` |
| Events by date | `ledger:by_date:{YYYY-MM-DD}` |
| Events by agent | `ledger:by_agent:{agent_id}` |
| Active agents | `agent:active` |
| Intents by status | `intent:by_status:{status}` |
| Active delegations | `delegation:active` |

### Issue 2: [CORE] Implement POLICY storage and evaluation engine

**Priority:** High
**Labels:** `core`, `policy`, `governance`

**Description**
Build the policy storage layer and basic evaluation logic that Cece will use to check permissions.

**Acceptance Criteria**

- [ ] CRUD operations: `createPolicy`, `getPolicy`, `listPoliciesByScope`, `updatePolicy`, `deactivatePolicy`
- [ ] Policy schema validation (scope, rules array, conditions, actions)
- [ ] Implement `evaluatePolicy(scope, context)` → `{result, applied_policy_id, rule_matched}`
- [ ] Support rule priorities (higher numeric priority wins)
- [ ] Maintain indexes: `policy:scope:{scope}`, `policy:active`

**Schema Example**

```json
{
  "policy_id": "pol-20251130-a1b2c3",
  "scope": "email.send",
  "rules": [
    {
      "condition": "recipient.domain NOT IN approved_domains",
      "action": "require_human_approval",
      "priority": 100

- [ ] KV schema reference with all key patterns
- [ ] Query patterns cheat sheet
- [ ] Example: full lifecycle of a cross-tool workflow
- [ ] Security model: how policies and delegations interact

---

## Query Patterns Cheat Sheet

| Use Case | Query |
|----------|-------|
| Can Cece send email? | `delegation:by_delegate:agent:cece.governor.v1` → filter for `gmail.send` scope |
| What happened today? | `ledger:by_date:2025-11-30` |
| Who owns BlackRoad? | `claim:by_object:org:blackroad` → filter for `claim_type: ownership` |
| What policies apply to email? | `policy:scope:email.*` |
| What's Cece working on? | `intent:by_status:executing` → filter for `assigned_agent: cece.governor.v1` |

---

## Implementation Notes

### Cloudflare KV
- Use key patterns directly
- Values are JSON strings
- Index keys store JSON arrays of IDs

### D1 (if SQL needed)
- Each namespace becomes a proper table
- Index keys become actual indexes
- Add `JSONB` columns for flexible fields

### Railway (Redis/Postgres)
- Same patterns work with minor syntax adjustments
- Redis for hot paths (active intents, recent ledger)
- Postgres for cold storage and complex queries
