fix: correct Makefile syntax (tabs for recipe lines)

- Add connectors/ directory with base infrastructure
- Implement SourceEvent unified schema (source/account/thread/author/timestamp/content/attachments/raw_ref/hash/consent_scope)
- Create BaseConnector abstract class with checkpoint/dedup/consent gates
- Implement TwitterArchiveConnector for official Twitter/X data exports
- Add run_connector.py CLI entry point
- Add comprehensive test suite (13 tests, all passing)
- Add connectors/README.md with usage docs
- Add Makefile targets: test-connectors, run-connector, connectors-help
- Reference parent EPIC #194 and issue #233

This is the foundational connector pack. Future work: Discord, Slack, WhatsApp, Notion, iMessage, Google.

+# Sovereign Personal Archive Connector Pack
+
+This directory contains the connector infrastructure for ingesting personal archives
+(Discord, Slack, WhatsApp, Notion, iMessage, X/Twitter, Google) into the compounding-intelligence
+knowledge pipeline.
+
+## Quick Start
+
+```bash
+# Run the Twitter archive connector
+python3 scripts/run_connector.py twitter \
+  --source ~/Documents/TwitterArchive \
+  --output events.jsonl \
+  --limit 100
+```
+
+## Connector Output Format
+
+Each connector emits `SourceEvent` objects (one JSON line per event):
+
+```json
+{
+  "source": "twitter",
+  "account": "user_archive",
+  "thread_or_channel": "tweet_123456",
+  "author": "user_archive",
+  "timestamp": "2026-04-26T08:30:00+00:00",
+  "content": "Tweet text here",
+  "attachments": ["https://..."],
+  "raw_ref": "twitter:archive:tweet.js:123456",
+  "hash": "sha256...",
+  "consent_scope": "memory_only",
+  "metadata": { "tweet_id": "123456", "favorite_count": 10 }
+}
+```
+
+## Connector Registry
+
+| Name           | Source Format                | Status   |
+|----------------|-----------------------------|----------|
+| twitter_archive| Official Twitter data export| ✅ Working |
+| discord_archive| Discord data package / JSON | ⏳ Planned |
+| slack_archive  | Slack export / API         | ⏳ Planned |
+| whatsapp_archive| WhatsApp Desktop export   | ⏳ Planned |
+| notion_archive | Notion markdown/SQLite     | ⏳ Planned |
+| imessage_archive| macOS local chat storage  | ⏳ Planned |
+| google_archive | Google Workspace CLI       | ⏳ Planned |
+
+## 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.

-Codebase Genome Diff — Detect structural changes between two versions.
-
-Compares two git refs (commits, branches, tags) and produces a human-readable
-report of structural changes:
-  • Added/removed/renamed files
-  • Changed functions/classes (signature modifications)
-  • New dependencies (imports, requirements, etc.)
-
-Usage:
-    python3 scripts/genome_diff.py --ref1 <commit1> --ref2 <commit2>
-    python3 scripts/genome_diff.py --ref1 main --ref2 feature-branch
-    python3 scripts/genome_diff.py --ref1 v1.0 --ref2 v2.0 --output report.txt
