# Roadmap: v1.90 Hypothesis Route Transition Authority Surface

## Result

`v1.90` closed successfully.

## Phases

- [x] **Phase 164: Hypothesis Route Transition Authority Surface**

## Target Outcome

- one explicit `route_transition_authority` surface derived from route
  transition commitment plus current route artifacts
- one runtime/read path that shows whether a committed route has become the
  authoritative bounded truth across runtime surfaces
- one bounded acceptance lane proving transition-authority visibility without
  widening into fresh runtime mutation

## Completion Summary

Phase `164` shipped the bounded authority surface on top of the existing route
transition ladder and left fresh runtime mutation deferred.

### Phase 164: Hypothesis Route Transition Authority Surface

**Goal:** Close the next post-`v1.89` gap by turning transition commitment into
one explicit authority surface instead of leaving operators to infer whether a
committed route has become the authoritative bounded truth.
**Requirements:**
- runtime surfaces can materialize a bounded transition-authority summary from
  route transition commitment plus current route artifacts
- replay/read paths expose the authority decision directly
- the transition-authority surface coexists with transition commitment and
  helper mechanisms instead of replacing them
- one isolated acceptance lane proves the bounded transition-authority path on
  an isolated temp kernel root
**Depends on:** v1.89 completion
**Plans:** 1 plan

Plans:
- [x] `164-01` Add route transition-authority summary to runtime/replay
  surfaces and isolated acceptance
