DanConwayDev c29191b1e1 feat(grasp-05): implement archive mode for backup/mirror operation
Implements GRASP-05 specification for accepting repository announcements
that don't list this relay, enabling archive, mirror, and backup use cases.

Core Features:
- Three whitelist formats: <npub>, <npub>/<identifier>, <identifier>
- Archive-all mode for complete ecosystem mirrors
- Fail-fast npub validation at startup
- Read-only enforcement (archived repos reject pushes)
- Full GRASP-02 sync (git data + Nostr events)
- Dynamic archive status (no flags/metadata)

Implementation:
- Add ArchiveWhitelistEntry enum with Pubkey/Repository/Identifier variants
- Add ArchiveConfig with validation and matching logic
- Update AnnouncementResult to include AcceptArchive variant
- Refactor validate_announcement() to return AnnouncementResult with archive check
- Update AnnouncementPolicy with catch-all pattern for cleaner code
- Wire archive config through builder and policy layers

Configuration:
- NGIT_ARCHIVE_ALL: Accept all announcements (⚠️ storage risk)
- NGIT_ARCHIVE_WHITELIST: Comma-separated whitelist entries
- Updated docs, .env.example, and nix/module.nix

Testing:
- 28 unit tests for config parsing and whitelist matching
- 7 integration tests for archive mode validation
- All 296 tests passing

Validation Priority:
1. Lists our service → Accept (GRASP-01, read/write)
2. Is maintainer → AcceptMaintainer (multi-maintainer, read/write)
3. Matches archive config → AcceptArchive (GRASP-05, read-only)
4. None of above → Reject

Security Considerations:
- Archive-all mode has storage/bandwidth DoS risk
- Identifier-only format matches any pubkey (use npub/identifier for high-value)
- Invalid npubs cause startup failure (fail-fast)

Documentation:
- Concise explanation focused on rationale
- Reference docs updated with all config options
- README updated to reflect completed feature
- Removed from roadmap, added to compliance section

See docs/explanation/grasp-05-archive.md for details.

Reference

Information-oriented documentation - Technical details and specifications.


What Is Reference Documentation?

Reference documentation provides factual, technical information that you look up when needed.

Characteristics:

  • ✅ Information-oriented (facts and data)
  • ✅ Comprehensive and accurate
  • ✅ Structured for lookup
  • ✅ Dry and to-the-point
  • ✅ Maintained as code changes

Not reference:

  • ❌ Learning materials (those are Tutorials)
  • ❌ Problem-solving guides (those are How-To)
  • ❌ Conceptual explanations (those are Explanation)

How to Use Reference Documentation

  1. Know what you're looking for - Reference is for lookup, not learning
  2. Use search or table of contents - Find the specific detail you need
  3. Check version - Ensure docs match your version
  4. Verify with code - Reference should match implementation

Not sure if this is what you need?
