 ## Project Overview

-**What:** A system that turns 1B+ daily agent tokens into durable, compounding fleet intelligence.
+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.

-**Why:** Every agent session starts at zero. The same mistakes get made repeatedly — the same HTTP 405 is rediscovered as a branch protection issue, the same token path is searched for from scratch. Intelligence evaporates when the session ends.

-**How:** Three pipelines form a compounding loop:

-### Pipeline 1: Harvester
+## Entry Points

-**Status:** Prompt designed. Script not implemented.
+### Core Pipelines

-Reads finished session transcripts (JSONL). Uses `templates/harvest-prompt.md` to extract durable knowledge into five categories:
+| 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` |

-| Category | Description | Example |
-|----------|-------------|---------|
-| `fact` | Concrete, verifiable information | "Repository X has 5 files" |
-| `pitfall` | Errors encountered, wrong assumptions | "Token is at ~/.config/gitea/token, not env var" |
-| `pattern` | Successful action sequences | "Deploy: test → build → push → webhook" |
-| `tool-quirk` | Environment-specific behaviors | "URL format requires trailing slash" |
-| `question` | Identified but unanswered | "Need optimal batch size for harvesting" |
+### Analysis & Quality

-Output schema per knowledge item:
-```json
-{
-  "fact": "One sentence description",
-  "category": "fact|pitfall|pattern|tool-quirk|question",
-  "repo": "repo-name or 'global'",
-  "confidence": 0.0-1.0
-}
-```
+| 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 |
+| `diff_analyzer.py` | Analyze code diffs for improvement signals |
+| `improvement_proposals.py` | Generate ranked improvement proposals |
+| `priority_rebalancer.py` | Rebalance priorities across proposals |
+| `automation_opportunity_finder.py` | Find manual steps that can be automated |
+| `dead_code_detector.py` | Detect unused code |
+| `dependency_graph.py` | Map dependency relationships |
+| `perf_bottleneck_finder.py` | Find performance bottlenecks |
+| `refactoring_opportunity_finder.py` | Identify refactoring targets |
+| `gitea_issue_parser.py` | Parse Gitea issues for knowledge extraction |

-### Pipeline 2: Bootstrapper
+### Automation

-**Status:** Not implemented.
+| Script | Purpose |
+|--------|---------|
+| `session_pair_harvester.py` | Extract training pairs from sessions |

-Queries knowledge store before session start. Assembles a compact 2k-token context from relevant facts. Injects into session startup so the agent begins with full situational awareness.
-
-### Pipeline 3: Measurer
-
-**Status:** Not implemented.
-
-Tracks compounding metrics: knowledge velocity (facts/day), error reduction (%), hit rate (knowledge used / knowledge available), task completion improvement.

+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

 ## Key Abstractions

-### Knowledge Item
-The atomic unit. One sentence, one category, one confidence score. Designed to be small enough that 1000 items fit in a 2k-token bootstrap context.
+### Knowledge Item (fact/pitfall/pattern/quirk/question)
+```json
+{
+  "fact": "Gitea token is at ~/.config/gitea/token",
+  "category": "tool-quirk",
+  "repo": "global",
+  "confidence": 0.9,
+  "evidence": "Found during clone attempt",
+  "source_session": "2026-04-13_abc123",
+  "extracted_at": "2026-04-13T20:00:00Z"
+}
+```

-### Knowledge Store
-A directory structure that mirrors the fleet's mental model:
- `global/` — knowledge that applies everywhere (tool quirks, environment facts)
- `repos/` — knowledge specific to each repo
- `agents/` — knowledge specific to each agent type
+### SessionSummary (session_metadata.py)
+Extracted metadata per session: duration, token count, tools used, repos touched, error count, outcome.

-### Confidence Score
-0.0–1.0 scale. Defines how certain the harvester is about each extracted fact:
- 0.9–1.0: Explicitly stated with verification
- 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
+### Gap / GapReport (knowledge_gap_identifier.py)
+Structured gap analysis: untested functions, undocumented APIs, missing tests. Severity: critical/high/medium/low.

-### Bootstrap Context
-The 2k-token injection that a new session receives. Assembled from the most relevant knowledge items for the current task, filtered by confidence > 0.7, deduplicated, and compressed.
+### Knowledge Index (knowledge/index.json)
+Machine-readable fact store. 12KB, populated with real data. Categories: fact, pitfall, pattern, tool-quirk, question.

---

 ## API Surface

-### Internal (scripts not yet implemented)
+### LLM API (consumed)
+| Provider | Endpoint | Usage |
+|----------|----------|-------|
+| Nous Research | `https://inference-api.nousresearch.com/v1` | Knowledge extraction |
+| Ollama | `http://localhost:11434/v1` | Local fallback |

-| Script | Input | Output | Status |
-|--------|-------|--------|--------|
-| `harvester.py` | Session JSONL path | Knowledge items JSON | PLANNED |
-| `bootstrapper.py` | Repo + agent type | 2k-token context string | PLANNED |
-| `measurer.py` | Knowledge store path | Metrics JSON | PLANNED |
-| `session_reader.py` | Session JSONL path | Parsed transcript | PLANNED |
-
-### Prompt (templates/harvest-prompt.md)
-
-The extraction prompt is the core "API." It takes a session transcript and returns structured JSON. It defines:
- Five extraction categories
- Output format (JSON array of knowledge items)
- Confidence scoring rubric
- Constraints (no hallucination, specificity, relevance, brevity)
- Example input/output pair
-
---
+### 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_refactoring_opportunity_finder.py` | Refactoring signals |
+| `test_knowledge_gap_identifier.py` | Gap analysis |
+| `test_perf_bottleneck_finder.py` | Perf bottleneck detection |

-### What's Missing
+### Coverage Gaps

-1. **Harvester integration test** — Does the prompt actually extract correct knowledge from real transcripts?
-2. **Bootstrapper test** — Does it assemble relevant context correctly?
-3. **Knowledge store test** — Does the index.json maintain consistency?
-4. **Confidence calibration test** — Do high-confidence facts actually prove true in later sessions?
-5. **Deduplication test** — Are duplicate facts across sessions handled?
-6. **Staleness test** — How does the system handle outdated knowledge?
-
---
+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

-1. **No secrets in knowledge store** — The harvester must filter out API keys, tokens, and credentials from extracted facts. The prompt constraints mention this but there is no automated guard.
+### 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

-2. **Knowledge poisoning** — A malicious or corrupted session could inject false facts. Confidence scoring partially mitigates this, but there is no verification step.
+### 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

-3. **Access control** — The knowledge store has no access control. Any process that can read the directory can read all facts. In a multi-tenant setup, this is a concern.
+### 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

-4. **Transcript privacy** — Session transcripts may contain user data. The harvester must not extract personally identifiable information into the knowledge store.

-```
-Month 1:  15,000 facts, sessions 20% faster
-Month 2:  45,000 facts, sessions 40% faster, first-try success up 30%
-Month 3:  90,000 facts, fleet measurably smarter per token
-```
-
-Each new session is better than the last. The intelligence compounds.

+## Design Principles
+
+1. **Local-first**: Connectors operate on user-owned exports or explicit API credentials.
+2. **Incremental**: Checkpoint files (~/.cache/connectors/) allow resumable processing.
+3. **Consent-gated**: Default `consent_scope=memory_only` — explicit opt-in for broader use.
+4. **Provenance-preserving**: `metadata` retains all raw fields; `hash` enables deduplication.
+5. **Sovereign**: No ambient scraping. No cloud dependency unless user explicitly configures tokens.
+
+## Writing a New Connector
+
+Subclass `BaseConnector` from `connectors/base.py` and implement:
+
+- `discover_sources(root: Path) -> Iterator[Path|str]` — find source files or IDs
+- `parse_source(source) -> Iterator[SourceEvent]` — emit normalized events
+
+Register in `connectors/__init__.py` `_REGISTRY` dict.
+
+See `connectors/twitter_archive.py` for a complete example.

+Knowledge Freshness Cron — Detect stale entries from code changes (Issue #200)
+
+Automatically detects when knowledge entries become stale due to code changes.
+
+Detection Method:
+1. Track source file hash alongside knowledge entry
+2. Compare current file hashes vs stored
+3. Mismatch → flag entry as potentially stale
+4. Report stale entries and optionally re-extract
+
+Usage:
+    python3 scripts/freshness.py --knowledge-dir knowledge/
+    python3 scripts/freshness.py --knowledge-dir knowledge/ --json
+    python3 scripts/freshness.py --knowledge-dir knowledge/ --repo /path/to/repo

Timmy	55adcb31dc	fix: implement refactoring_opportunity_finder API (#210 ) Some checks failed Test / pytest (pull_request) Failing after 30s Details The test file expects compute_file_complexity(), calculate_refactoring_score(), and FileMetrics from the script, but only a stub generate_proposals() existed. Implemented: - compute_file_complexity(): AST-based cyclomatic complexity analysis - calculate_refactoring_score(): weighted scoring (complexity, size, churn, coverage) - FileMetrics: dataclass with all required fields - Full generate_proposals() that scans directories and produces scored proposals All 10 tests pass. py_compile succeeds.
