## Context
History files (.md files tracking decisions, spawns, outcomes) are read cold by future agents. Stale or incorrect entries poison decision-making downstream. The Kobayashi incident proved this: history said "Brady decided v0.6.0" when Brady had reversed that to v0.8.17. Future spawns read the wrong truth and repeated the mistake.
## Patterns
- **Record the final outcome**, not the initial request.
- **Wait for confirmation** before writing to history — don't log intermediate states.
- **If a decision reverses**, update the entry immediately — don't leave stale data.
- **One read = one truth.** A future agent should never need to cross-reference other files to understand what actually happened.
