# Phase 115: Research Taste Contract - Context

**Gathered:** 2026-04-11
**Status:** Implemented and verified
**Mode:** First implementation phase for `v1.61`

<domain>
## Phase Boundary

Open `v1.61` by locking a bounded contract for the runtime-side research taste
surface.

## Implementation Decisions

### Locked decisions

- represent research taste as runtime-side durable state, not canonical
  scientific truth
- make preferred formalisms, physical intuition, and surprise-handling visible
  through one bounded topic surface
- require helper, service, CLI, and schema coverage before production wiring

</decisions>
