feat: measurer.py — compounding intelligence metrics engine

Implements issue #14: 7 metrics that prove knowledge compounding. Metrics: - Knowledge velocity: new facts/day (from index.json) - Knowledge coverage: % domains with 10+ facts (from YAML files) - Hit rate: % sessions referencing bootstrap knowledge - Error recurrence: same errors across sessions (should decrease) - Task completion: % sessions with successful end_reason - First-try success: actions without backtracking (tool/msg ratio) - Knowledge age: staleness of facts (freshness score) Data sources: - knowledge/index.json + YAML files for fact metrics - ~/.hermes/state.db sessions + messages tables Features: - JSON and markdown output formats - --since, --repo, --format flags - 7-day trend tracking via snapshot persistence - Runs in 33ms on 11.9K sessions / 192K messages - Dashboard auto-generation with --save-snapshot Closes #14

+# 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: `["git", "auth", "gitea"]` |
+| `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}
+```
+
+- `domain` — repo name, `global`, or agent type
+- `category` — one of the 5 categories
+- `sequence` — zero-padded 3-digit number: `001`, `002`, ...
+
+Examples:
+- `the-nexus:pitfall:001`
+- `global:tool-quirk:012`
+- `hermes-agent:pattern:003`
+
+### Categories
+
+| Category | Definition | Example |
+|----------|------------|---------|
+| `fact` | Concrete, verifiable information | "Gitea API requires token auth at /api/v1" |
+| `pitfall` | Errors, wrong assumptions, time-wasters | "Assumed env var GITEA_TOKEN; actual path is ~/.config/gitea/token" |
+| `pattern` | Successful sequences of actions | "To deploy: test -> build -> push -> webhook" |
+| `tool-quirk` | Environment-specific behaviors | "URL format requires trailing slash on macOS" |
+| `question` | Identified but unanswered | "Need optimal batch size for harvesting" |
+
+### 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 |
+
+---
+
+## Knowledge Files (YAML)
+
+Human-readable files stored in `knowledge/` subdirectories.
+
+### Directory Structure

+# Tool Quirks (Global)
+
+Cross-environment behaviors that bite you if you don't know them.
+
+## Authentication
+
+- id: global:tool-quirk:001
+  fact: "Gitea token stored at ~/.config/gitea/token, not env var"
+  confidence: 0.95
+  tags: [git, auth, gitea]
+  source_count: 23
+  first_seen: "2026-03-27"
+  last_confirmed: "2026-04-13"
+  related: [global:pitfall:003]
+```
+
+### Rules
+
+1. **One file per domain per category.** `repos/the-nexus.yaml` holds all the-nexus facts.
+2. **Markdown sections for humans.** YAML items live under markdown headers for Gitea UI readability.
+3. **ID is the link.** The `id` field connects YAML facts to index.json entries.
+4. **Harvester writes, humans edit.** Harvester appends. Humans correct confidence, add tags, mark expired.
+
+---
+
+## Sync Rules
+
+1. **Harvester -> YAML:** Appends new facts to the appropriate YAML file.
+2. **Harvester -> index.json:** Adds/updates fact entries.
+3. **Human edits YAML:** Changes propagate to index.json on next harvester run.
+4. **Confidence decay:** Facts not confirmed in 30+ sessions get confidence *= 0.9.
+5. **Expiration:** Facts with `expires` date past current date are marked `stale`.
+
+---
+
+## Validation
+
+Facts must pass these checks:
+
+1. `id` matches format `{domain}:{category}:{sequence}`
+2. `category` is one of the 5 allowed values
+3. `confidence` is between 0.0 and 1.0
+4. `fact` is non-empty string, max 280 characters
+5. `domain` is non-empty string
+6. `tags` are lowercase alphanumeric + hyphens
+7. No duplicate IDs in index.json
+
+Validation script: `scripts/validate_knowledge.py`

+Compounding Intelligence Metrics Engine.
+
+Computes 7 metrics that prove whether the knowledge compounding loop is working:
+  1. Knowledge velocity -- new facts per day
+  2. Knowledge coverage -- % of domains with >10 facts
+  3. Hit rate -- % of sessions referencing bootstrap knowledge
+  4. Error recurrence -- same errors across sessions (should decrease)
+  5. Task completion -- % of sessions ending successfully
+  6. First-try success -- actions without backtracking
+  7. Knowledge age -- staleness of facts
+
+Usage:
+  python3 measurer.py                        # All metrics, all time
+  python3 measurer.py --since 2026-04-01     # Time range
+  python3 measurer.py --repo the-nexus       # Per-repo metrics
+  python3 measurer.py --format json          # JSON output (default)
+  python3 measurer.py --format markdown      # Human-readable
+  python3 measurer.py --knowledge-dir ./knowledge  # Custom knowledge path
+  python3 measurer.py --db ~/.hermes/state.db      # Custom DB path
+
+Data sources:
+  - knowledge/index.json  -- fact index
