reconcile: mark 312 archive sources, add 300 bidirectional links
- 131 sources → processed (matched to decisions/entities by proposal hash)
- 72 sources → null-result (test/spam)
- 109 sources → null-result (futardio unmatched, no KB output)
- 91 sources kept unprocessed (genuine backlog: health, ai-alignment, space-dev, etc.)
- 117 decisions get source_archive backlinks
- 131 archive sources get derived_items forward links
- Linking pattern: frontmatter only, file paths as identifiers (Ganymede Option A)
Script: reconcile-sources.py (proposal hash matching + entity name matching)
