# Roadmap: v1.82 Hypothesis Route Transition Resolution Surface

## Result

`v1.82` is complete.

## Overview

`v1.82` closed the next post-`v1.81` research-control gap around
hypothesis-aware route transition resolution. It derived one bounded
`route_transition_resolution` summary from the current route transition intent,
transition receipt, and active-route state, surfaced the resolved handoff
outcome through runtime status and replay, and proved the bounded coexistence
path with a dedicated isolated acceptance lane.

**Phases:** 156
**Total Plans:** 1
**Total Tasks:** 2
**Shipped:** 2026-04-12

## Phase Details

### Phase 156: Hypothesis Route Transition Resolution Surface

**Goal:** Add one durable route transition-resolution summary for the current
handoff outcome and expose it through runtime/read-path/replay flows without
widening into fresh runtime mutation.

**Plans:** 1 plan

Plans:

- [x] `156-01`: add route transition-resolution summary to runtime/replay
  surfaces and isolated acceptance

**Outcome:**

- landed `route_transition_resolution` payload construction and rendering on
  the runtime/read-path layer
- surfaced pending versus resolved versus none transition resolution through
  runtime status, the runtime protocol note, and replay
- aligned schema, docs, and isolated acceptance coverage for the bounded route
  transition-resolution path

## Milestone Summary

**Key Accomplishments:**

- route transition intent, transition receipt, and active-route alignment now
  join into one explicit transition-resolution summary
- runtime status and replay now keep the resolved handoff outcome visible
  without replacing transition receipt or helper mechanisms
- one isolated acceptance lane now proves pending, resolved, and none
  transition-resolution visibility stays declarative and does not widen into
  fresh runtime mutation

**Issues Resolved:**

- closed the gap where operators could see transition intent and receipt but
  still had to manually reconcile those with the current active-route state
- closed the gap where route-transition surfaces still had to be mentally
  composed to understand the current resolved handoff outcome

**Issues Deferred:**

- explicit route-transition discrepancy surface when resolution and upstream
  artifacts disagree in a way that deserves operator attention
- automatic candidate reactivation and parent-topic reintegration mutation
- automatic branch spawning and multi-branch scheduling

**Technical Debt / Honest Gaps:**

- the first slice makes route-transition resolution visible, but it does not
  yet surface one explicit discrepancy lane for inconsistent transition state
  that should be flagged to the operator

For current planning state after `v1.82`, continue from the next fresh
milestone definition.
