**Gathered:** 2026-03-27
**Status:** Ready for planning
**Mode:** Auto-generated (infrastructure/testing phase — discuss skipped)

<domain>
## Phase Boundary

Bit-exact oracle tests prove Aion mode correctness before any service integration -- single-day equivalence, multi-day continuity, and gap flag lifecycle

## Implementation Decisions

### Claude's Discretion

All implementation choices are at Claude's discretion — pure testing/validation phase. Use ROADMAP phase goal, success criteria, and codebase conventions to guide decisions.

## Existing Code Insights

Codebase context will be gathered during plan-phase research.
