# Archival Log: Decisions

**Timestamp:** 2026-03-27T21:42:00Z  
**Agent:** Scribe (Copilot)  
**Trigger:** Automated archival gate

## Task
Archive decisions.md entries older than 7 days to free up context. Decision entries from 2026-02-21 through 2026-03-25 moved to append-only archive.

## Outcome
✅ SUCCESS

## Changes
- **decisions.md**: Trimmed from 385KB → 11.9KB
  - Foundational directives preserved (Type safety, Hook governance, Node.js runtime, etc.)
  - Recent entries (2026-03-26+) preserved
  - 71 dated entries (2026-02-21:2026-03-25) archived
  
- **decisions-archive.md**: Created 365.1KB archive
  - 71 entries preserved append-only
  - Full history intact for reference
  - No data loss

## Verification
- ✅ Archive gate (decisions.md < 20KB): **PASS**
- ✅ All foundational directives present in decisions.md
- ✅ All archived entries present in decisions-archive.md
- ✅ Git commit successful: `b8b4c5ae`

## Measurements
| Metric | Value |
|--------|-------|
| Entries archived | 71 |
| Archive date range | 2026-02-21 : 2026-03-25 |
| decisions.md pre | 385 KB |
| decisions.md post | 11.9 KB |
| decisions-archive.md | 365.1 KB |
| Reduction | 96.9% |
| Context savings | ~373 KB |

## Summary
Successfully archived 71 dated decision entries spanning 33 days of team decisions. The decisions.md file is now below the 20KB archival gate threshold (11.9KB), reducing agent context load while preserving full history in append-only archive. All foundational directives remain in active decisions.md for team reference.

## Impact
- **Agent context efficiency:** All agents now load ~373KB less decision context
- **No functionality loss:** Archived decisions remain accessible via decisions-archive.md
- **Append-only integrity:** Archive file can only grow; merge conflicts impossible
- **Future gate compliance:** Next archival not needed until decisions.md reaches 20KB again
