feat(#10 ): knowledge file format schema + example knowledge files

- SCHEMA.md: full specification for index.json and YAML knowledge files - knowledge/global/pitfalls.yaml: 8 cross-repo pitfalls - knowledge/global/tool-quirks.yaml: 7 environment quirk facts - knowledge/repos/hermes-agent.yaml: 8 per-repo pitfalls (cron, paths, SSH) - knowledge/repos/the-nexus.yaml: 6 per-repo pitfalls (merge, server, deploy) - scripts/validate_knowledge.py: schema validator (29 facts, all passing) - knowledge/index.json: populated with 29 seed facts from real fleet data Design decisions: - YAML for humans, index.json for machines - ID format: domain:category:sequence for dedup and linking - 5 categories: fact, pitfall, pattern, tool-quirk, question - Confidence 0.0-1.0 with defined ranges - Related facts by ID for graph traversal - Tags for searchability - Source count + dates for decay/expiry Acceptance criteria: - [x] Directory structure created - [x] Schema documented (SCHEMA.md) - [x] index.json with real facts (29 total) - [x] Example knowledge files for 2 repos (hermes-agent, the-nexus) - [x] Validation script passes

+# Knowledge File Format Specification
+
+**Version:** 1
+**Issue:** #10
+**Status:** Draft
+
+---
+
+## Overview
+
+The knowledge system has two layers:
+
+1. **index.json** — Machine-readable fact index. Fast lookups by ID, category, repo, tags.
+2. **Knowledge files** (YAML) — Human-readable, editable facts organized by domain.
+
+The harvester writes to both. The bootstrapper reads from index.json. Humans edit the YAML files directly.
+
+---
+
+## index.json Schema
+
+```json
+{
+  "version": 1,
+  "last_updated": "ISO-8601 timestamp",
+  "total_facts": 0,
+  "facts": []
+}
+```
+
+### Fact Object
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `id` | string | yes | Unique identifier: `{domain}:{category}:{sequence}` |
+| `fact` | string | yes | One-sentence description of the knowledge |
+| `category` | enum | yes | One of: `fact`, `pitfall`, `pattern`, `tool-quirk`, `question` |
+| `domain` | string | yes | Where this applies: repo name, `global`, or agent name |
+| `confidence` | float | yes | 0.0–1.0. How certain is this knowledge? |
+| `tags` | string[] | no | Searchable labels |
+| `source_count` | int | no | How many sessions confirmed this fact |
+| `first_seen` | date | no | ISO-8601 date first extracted |
+| `last_confirmed` | date | no | ISO-8601 date last seen in a session |
+| `expires` | date | no | Optional. After this date, fact is stale |
+| `related` | string[] | no | IDs of related facts |
+
+### ID Format: `{domain}:{category}:{sequence}`
+
+### Categories
+
+| Category | Definition |
+|----------|------------|
+| `fact` | Concrete, verifiable information |
+| `pitfall` | Errors, wrong assumptions, time-wasters |
+| `pattern` | Successful sequences of actions |
+| `tool-quirk` | Environment-specific behaviors |
+| `question` | Identified but unanswered |
+
+### Confidence Scoring
+
+| Range | Meaning |
+|-------|---------|
+| 0.9–1.0 | Explicitly stated and verified |
+| 0.7–0.8 | Clearly implied by multiple data points |
+| 0.5–0.6 | Suggested but not fully verified |
+| 0.3–0.4 | Inferred from limited data |
+| 0.1–0.2 | Speculative or uncertain |
+
+---
+
+## Directory Structure
+
+```
+knowledge/
+├── index.json                  # Machine-readable fact index
+├── SCHEMA.md                   # This file

+│   └── ...
+└── agents/                     # Agent-type knowledge
+    └── {agent-type}.yaml
+```
+
+## YAML File Format
+
+YAML files use frontmatter for metadata, then markdown sections with fact entries:
+
+```yaml
+---
+domain: global
+category: tool-quirk
+version: 1
+last_updated: "2026-04-13"

+  source_count: 5
+  first_seen: "2026-03-27"
+```
+
+## Validation
+
+Run `python scripts/validate_knowledge.py` to validate index.json.
