# Roadmap: v1.88 Hypothesis Route Transition Resumption Surface

## Result

`v1.88` is complete.

## Overview

`v1.88` closed the next post-`v1.87` research-control gap around
hypothesis-aware route transition resumption. It derived one bounded
`route_transition_resumption` summary from the current route transition
follow-through plus current route state, surfaced the bounded resumption state
through runtime status and replay, and proved the bounded coexistence path with
a dedicated isolated acceptance lane.

**Phases:** 162
**Total Plans:** 1
**Total Tasks:** 2
**Shipped:** 2026-04-12

## Phase Details

### Phase 162: Hypothesis Route Transition Resumption Surface

**Goal:** Add one durable route transition-resumption summary for the current
post-followthrough re-entry state and expose it through runtime/read-path/replay
flows without widening into fresh runtime mutation.

**Plans:** 1 plan

Plans:

- [x] `162-01`: add route transition-resumption summary to runtime/replay
  surfaces and isolated acceptance

**Outcome:**

- landed `route_transition_resumption` payload construction and rendering on
  the runtime/read-path layer
- surfaced `none`, `waiting_followthrough`, `pending`, and `resumed` state
  through runtime status, the runtime protocol note, and replay
- aligned schema, docs, and isolated acceptance coverage for the bounded route
  transition-resumption path

## Milestone Summary

**Key Accomplishments:**

- route transition follow-through and current route state now join into one
  explicit bounded resumption surface
- runtime status and replay now keep not-started, pending, and resumed state
  visible without replacing transition follow-through or helper mechanisms
- one isolated acceptance lane now proves bounded transition-resumption
  visibility stays declarative and does not widen into fresh runtime mutation

**Issues Resolved:**

- closed the gap where operators could see follow-through but still had to
  infer whether that follow-through had actually resumed on the bounded route
- closed the gap where route re-entry after follow-through still had no explicit
  transition-resumption surface

**Issues Deferred:**

- explicit route-transition commitment after resumption
- automatic route commit and follow-up runtime mutation
- automatic branch spawning and multi-branch scheduling

**Technical Debt / Honest Gaps:**

- the first slice makes route resumption visible, but it does not yet surface
  one explicit commitment lane for whether the resumed route has become the
  durable committed local lane

milestone definition.
