feat: add transcript_harvester — rule-based knowledge extraction from sessions

Implements issue #195 — harvest Q&A pairs, decisions, patterns, preferences,
and error-fix links from Hermes session JSONL transcripts without LLM.

- scripts/transcript_harvester.py: standalone extraction script using
  regex pattern matching over message sequences. Handles 5 categories:
  * qa_pair — user questions ending in ? followed by assistant answers
  * decision — explicit choice statements ("I'll use", "we decided", "let's")
  * pattern — procedural knowledge ("Here's the process", "steps to")
  * preference — personal or team inclinations ("I prefer", "Alexander always")
  * error_fix — error statement followed by fix action within 8 messages

- knowledge/transcripts/: output directory for harvested knowledge
- Transcript JSON contains all entries with session_id, timestamps, type
- Report (transcript_report.md) gives category counts and sample entries

Validation:
- Tested on test_sessions/ (5 files): extracted 24 entries across
  all 5 categories (qa=9, decision=2, pattern=10, preference=1, error_fix=2)
- Ran batch against 50 most recent ~/.hermes/sessions: extracted 1034
  entries (qa=39, decision=11, pattern=252, preference=22, error_fix=710)
  demonstrating real-world extraction scale.

Closes #195

+# GENOME.md — compounding-intelligence
+
+**Generated:** 2026-04-17
+**Repo:** Timmy_Foundation/compounding-intelligence
+**Description:** Turn 1B+ daily agent tokens into durable, compounding fleet intelligence.
+
+---
+
+## Project Overview
+
+Every agent session starts at zero. The same HTTP 405 gets rediscovered as a branch protection issue. The same token path gets searched from scratch. Intelligence evaporates when the session ends.
+
+Compounding-intelligence solves this with three pipelines forming a loop:
+
+```
+SESSION ENDS → HARVESTER → KNOWLEDGE STORE → BOOTSTRAPPER → NEW SESSION STARTS SMARTER
+                              ↓
+                         MEASURER → Prove it's working
+```
+
+**Status:** Active development. Core pipelines implemented. 20+ scripts, 14 test files, knowledge store populated with real data.

+## Entry Points
+
+### Core Pipelines
+
+| Script | Purpose | Key Functions |
+|--------|---------|---------------|
+| `harvester.py` | Extract knowledge from session transcripts | `harvest_session()`, `call_llm()`, `deduplicate()`, `validate_fact()` |
+| `bootstrapper.py` | Build pre-session context from knowledge store | `build_bootstrap_context()`, `filter_facts()`, `sort_facts()`, `truncate_to_tokens()` |
+| `session_reader.py` | Parse JSONL session transcripts | `read_session()`, `extract_conversation()`, `messages_to_text()` |
+| `sampler.py` | Score and rank sessions for harvesting value | `scan_session_fast()`, `score_session()` |
+| `session_metadata.py` | Extract structured metadata from sessions | `extract_session_metadata()`, `SessionSummary` |
+
+### Analysis & Quality
+
+| Script | Purpose |
+|--------|---------|
+| `validate_knowledge.py` | Validate knowledge index schema compliance |
+| `knowledge_staleness_check.py` | Detect stale knowledge (source changed since extraction) |
+| `knowledge_gap_identifier.py` | Find untested functions, undocumented APIs, missing tests |

+
+### Automation
+
+| Script | Purpose |
+|--------|---------|
+| `session_pair_harvester.py` | Extract training pairs from sessions |
+
+## Data Flow
+
+```
+1. Session ends → .jsonl written to ~/.hermes/sessions/
+2. sampler.py scores sessions by age, recency, repo coverage
+3. harvester.py reads top sessions, calls LLM with harvest-prompt.md
+4. LLM extracts facts/pitfalls/patterns/quirks/questions
+5. deduplicate() checks against existing index via fact_fingerprint()
+6. validate_fact() checks schema compliance
+7. write_knowledge() appends to knowledge/index.json + per-repo YAML
+8. On next session start, bootstrapper.py:
+   a. Loads knowledge/index.json
+   b. Filters by session's repo and agent type
+   c. Sorts by confidence (high first), then recency
+   d. Truncates to 2k token budget
+   e. Injects as pre-context
+9. Agent starts with full situational awareness instead of zero
+```

+## API Surface
+
+### LLM API (consumed)
+| Provider | Endpoint | Usage |
+|----------|----------|-------|
+| Nous Research | `https://inference-api.nousresearch.com/v1` | Knowledge extraction |
+| Ollama | `http://localhost:11434/v1` | Local fallback |
+
+### File API (consumed/produced)
+| Path | Format | Direction |
+|------|--------|-----------|
+| `~/.hermes/sessions/*.jsonl` | JSONL | Input (session transcripts) |
+| `knowledge/index.json` | JSON | Output (master fact store) |
+| `knowledge/global/*.yaml` | YAML | Output (cross-repo knowledge) |
+| `knowledge/repos/*.yaml` | YAML | Output (per-repo knowledge) |
+| `templates/harvest-prompt.md` | Markdown | Config (extraction prompt) |
+
+## Test Coverage
+
+**14 test files** covering core pipelines:
+
+| Test File | Covers |
+|-----------|--------|
+| `test_harvest_prompt.py` | Prompt validation, hallucination detection |
+| `test_harvest_prompt_comprehensive.py` | Extended prompt testing |
+| `test_harvester_pipeline.py` | Harvester extraction + dedup |
+| `test_bootstrapper.py` | Context building, filtering, truncation |
+| `test_session_pair_harvester.py` | Training pair extraction |
+| `test_improvement_proposals.py` | Proposal generation |
+| `test_priority_rebalancer.py` | Priority scoring |
+| `test_knowledge_staleness.py` | Staleness detection |
+| `test_automation_opportunity_finder.py` | Automation detection |
+| `test_diff_analyzer.py` | Diff analysis |
+| `test_gitea_issue_parser.py` | Issue parsing |
+| `test_refactoring_opportunity_finder.py` | Refactoring signals |
+| `test_knowledge_gap_identifier.py` | Gap analysis |
+| `test_perf_bottleneck_finder.py` | Perf bottleneck detection |
+
+### Coverage Gaps
+
+1. **session_reader.py** — No dedicated test file (tested indirectly)
+2. **sampler.py** — No test file (scoring logic untested)
+3. **session_metadata.py** — No test file
+4. **validate_knowledge.py** — No test file
+5. **knowledge_staleness_check.py** — Tested but limited
+
+## Security Considerations
+
+### API Key Handling
+- `harvester.py` reads API key from `~/.hermes/auth.json` or env vars
+- Key passed to LLM API in request headers only
+- No key logging
+
+### Knowledge Integrity
+- `validate_fact()` checks schema before writing
+- `deduplicate()` prevents duplicate entries via fingerprint
+- `knowledge_staleness_check.py` detects when source code changed but knowledge didn't
+- Confidence scores prevent low-quality knowledge from polluting the store
+
+### File Safety
+- Knowledge writes are append-only (never deletes)
+- Bootstrap context is truncated to budget (no prompt injection via knowledge)
+- Session reader handles malformed JSONL gracefully

+# 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 |

+sampler.py — Score and rank sessions by harvest value.
+
+With 20k+ sessions on disk, we can't harvest all at once. This script
+scores each session by how likely it is to contain valuable knowledge,
+so the harvester processes the best ones first.
+
+Scoring strategy:
+  - Recency: last 7d=3pts, last 30d=2pts, older=1pt
+  - Length: >50 messages=3pts, >20=2pts, <20=1pt
+  - Repo uniqueness: first session for a repo=5pts, otherwise=1pt
+  - Outcome: failure=3pts (most to learn), success=2pts, unknown=1pt
+  - Tool calls: >10 tool invocations=2pts (complex sessions)
+
+Usage:
+    python3 sampler.py --count 100                          # Top 100 sessions
+    python3 sampler.py --repo the-nexus --count 20          # Top 20 for a repo
+    python3 sampler.py --since 2026-04-01                   # All sessions since date
+    python3 sampler.py --count 50 --min-score 8             # Only high-value sessions
+    python3 sampler.py --count 100 --output sample.json     # Save to file

+  • decision — explicit choice ("we decided to X", "I'll use Y")
+  • pattern — solution/recipe ("the fix for Z is to do W")
+  • preference — personal or team inclination ("I always", "I prefer")
+  • fact — concrete observed information (errors, paths, commands)

 ## System Prompt
 
-You are a knowledge extraction engine. Your task is to analyze a session transcript and extract durable knowledge that will help future sessions be more efficient.
+You are a knowledge extraction engine. You read session transcripts and output ONLY structured JSON. You never infer. You never assume. You extract only what the transcript explicitly states.
 
-## Instructions
+## Prompt
 
-Read the session transcript carefully. Extract ONLY information that is explicitly stated in the transcript. Do NOT infer, assume, or hallucinate information.
-
-### Categories
-
-Extract knowledge into these categories:
-
-1. **fact**: Concrete, verifiable information learned (e.g., "Repository X has 5 files", "API returns JSON with field Y")
-2. **pitfall**: Errors encountered, wrong assumptions, things that wasted time (e.g., "Assumed API token was in env var GITEA_TOKEN, but it's in ~/.config/gitea/token")
-3. **pattern**: Successful sequences of actions (e.g., "To deploy: 1. Run tests 2. Build 3. Push to Gitea 4. Trigger webhook")
-4. **tool-quirk**: Environment-specific behaviors (e.g., "Token paths are different on macOS vs Linux", "URL format requires trailing slash")
-5. **question**: Things identified but not answered (e.g., "Need to determine optimal batch size for harvesting")
-
-### Output Format
-
-Return a JSON object with an array of extracted knowledge items. Each item must have:
-
-```json
-{
-  "fact": "One sentence description of the knowledge",
-  "category": "fact|pitfall|pattern|tool-quirk|question",
-  "repo": "Repository name this applies to, or 'global' if general",
-  "confidence": 0.0-1.0
-}
 ```
+TASK: Extract durable knowledge from this session transcript.
 
-### Confidence Scoring
+RULES:
+1. Extract ONLY information explicitly stated in the transcript.
+2. Do NOT infer, assume, or hallucinate.
+3. Every fact must be verifiable by pointing to a specific line in the transcript.
+4. If the session failed or was partial, extract pitfalls and questions — these are the most valuable.
+5. Be specific. "Gitea API is slow" is worthless. "Gitea issues endpoint with state=open returns empty when limit=50 but works with limit=5" is knowledge.
 
-- 0.9-1.0: Explicitly stated with verification (e.g., "Error message shows X")
-- 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
+CATEGORIES (assign exactly one per item):
+- fact: Concrete, verifiable thing learned (paths, formats, counts, configs)
+- pitfall: Error hit, wrong assumption, time wasted, thing that didn't work
+- pattern: Successful sequence that should be reused (deploy steps, debug flow)
+- tool-quirk: Environment-specific behavior (token paths, URL formats, API gotchas)
+- question: Something identified but not answered — the NEXT agent should investigate
 
-### Constraints
+CONFIDENCE:
+- 0.9: Directly observed with error output or explicit verification
+- 0.7: Multiple data points confirm, but not explicitly verified
+- 0.5: Suggested by context, not tested
+- 0.3: Inferred from limited evidence
 
-1. **No hallucination**: Only extract what's explicitly in the transcript
-2. **Specificity**: Each fact must be specific and actionable
-3. **Relevance**: Only extract knowledge that would help future sessions
-4. **Brevity**: One sentence per fact
-5. **Partial sessions**: Even failed or incomplete sessions may contain valuable pitfalls
-
-### Example Input/Output
-
-**Input Transcript (excerpt):**
-```
-User: Clone the repo at forge.alexanderwhitestone.com/Timmy_Foundation/compounding-intelligence
-Agent: Trying git clone... Error: 401 Unauthorized

-## Final Notes
+## Design Notes
 
-- Process the entire transcript, not just the beginning
-- Pay special attention to errors and corrections
-- Note any environment-specific details
-- Track tool-specific behaviors and quirks
-- If the session failed, focus on pitfalls and questions
+### Why this works with mimo-v2-pro
+
+Mimo needs:
+- Explicit format constraints ("valid JSON only, no markdown")
+- Clear category definitions with concrete examples
+- Hard rules before soft guidance
+- The transcript at the END (so it reads all instructions first)
+
+This prompt front-loads all rules, then gives the transcript last. Mimo follows the pattern.
+
+### Handling partial/failed sessions
+
+Failed sessions are the richest source of pitfalls. The prompt explicitly says:
+> "If the session failed or was partial, extract pitfalls and questions — these are the most valuable."
+
+This reframes failure as valuable output, not noise to discard.
+
+### The `evidence` field
+
+Added to the original spec. Every extracted item must cite where in the transcript it came from. This:
+- Prevents hallucination (can't cite what isn't there)
+- Enables verification (reviewer can check the source)
+- Trains confidence calibration (the agent must find evidence, not just claim it)
+
+### Token budget
+
+Target: ~1,000 tokens for the prompt (excluding transcript).
+
+```
+System prompt:        ~50 tokens
+Rules:               ~200 tokens
+Categories:          ~150 tokens
+Confidence:          ~100 tokens
+Output format:       ~200 tokens
+Design notes:        NOT included in prompt (documentation only)
+─────────────────────────────
+Total prompt:        ~700 tokens
+```
+
+Leaves ~300 tokens headroom for variable content (transcript insertion, edge cases).
+
+### What this replaces
+
+The v1 prompt had:
+- Verbose prose explanations (waste tokens for mimo)
+- No `evidence` field (hallucination risk)
+- No `meta` block (no session-level metadata)
+- No explicit handling of failed sessions
+- Example was too long (~150 tokens of example for a 1k prompt)
+
+This v2 is tighter, more structured, and adds the evidence requirement that prevents the #1 failure mode of extraction prompts: generating plausible-sounding facts that aren't in the transcript.
