# Roadmap: v1.76 Hypothesis Route Re-entry Surface

## Result

`v1.76` is complete.

## Overview

`v1.76` closed the next post-`v1.75` research-control gap around parked-route
re-entry visibility. It derived one bounded `route_reentry` summary from
deferred-buffer and follow-up return contracts, surfaced deferred waiting
conditions plus ready child-route returns through runtime status and replay, and
proved the bounded coexistence path with a dedicated isolated acceptance lane.

**Phases:** 150
**Total Plans:** 1
**Total Tasks:** 2
**Shipped:** 2026-04-12

## Phase Details

### Phase 150: Hypothesis Route Re-entry Surface

**Goal:** Add one durable route re-entry summary for parked hypotheses and
expose it through runtime/read-path/replay flows without auto-reactivating
deferred candidates or patching the parent topic from child returns.

**Plans:** 1 plan

Plans:

- [x] `150-01`: add route re-entry summary to runtime/replay surfaces and
  isolated acceptance

**Outcome:**

- landed `route_reentry` payload construction and rendering on the
  runtime/read-path layer
- surfaced deferred reactivation conditions plus follow-up return readiness
  through runtime status, the runtime protocol note, and replay
- aligned schema, docs, and isolated acceptance coverage for the bounded
  route re-entry path

## Milestone Summary

**Key Accomplishments:**

- parked hypotheses now surface whether they are still waiting, re-entry-ready,
  or still owe a child-route return contract
- runtime status and replay now keep deferred reactivation conditions and
  follow-up return readiness visible without reconstructing them from separate
  artifacts
- one isolated acceptance lane now proves re-entry visibility stays declarative
  and does not auto-reactivate the deferred route or write a reintegration
  receipt

**Issues Resolved:**

- closed the gap where operators could see parked-route obligations but not the
  exact re-entry conditions or return readiness behind them
- closed the gap where deferred waiting state and child-route return state were
  split across separate artifacts without one hypothesis-level summary

**Issues Deferred:**

- automatic candidate reactivation and parent-topic reintegration mutation
- automatic branch spawning and multi-branch scheduling
- explicit handoff summaries that turn re-entry-ready parked routes into
  concrete next-step candidates

**Technical Debt / Honest Gaps:**

- the first slice makes parked-route re-entry visible, but it does not yet say
  which ready parked route should actually become the next concrete handoff on
  the parent topic

For current planning state after `v1.76`, continue from the next fresh
milestone definition.
