## Plan Intent

This plan executes one bounded next slice:

`G6 host-bridge entry readiness`

## Scope Guardrails

1. do not execute a `G6` real sample
2. do not implement host-runtime directly
3. do not open `G8`
4. do not reopen `G7`
5. do not open `G4 / G5`

## Workstreams

1. `WS1` Freeze entry-readiness scope
2. `WS2` Define bounded readiness criteria
3. `WS3` Publish one bounded readiness result

## Phase 0: Freeze the Boundary

### Objective

Lock the plan to entry-readiness only.

### Tasks

1. freeze `G6` as the only target
2. freeze implementation and real execution as out of scope

### Acceptance Criteria

1. no broader host-runtime work begins under this plan

## Phase 1: Define Readiness Criteria

### Objective

Turn the explicit callback verification model into bounded entry-readiness criteria.

### Tasks

1. define which semantics are required before `G6` entry can open
2. define which semantics remain optional
3. define the minimal readiness threshold

### Acceptance Criteria

1. entry-readiness criteria are explicit and bounded

## Phase 2: Publish the Bounded Result

### Objective

Turn the readiness model into one bounded next artifact.

### Tasks

1. publish the readiness result
2. if needed, publish the next bounded follow-up plan

### Acceptance Criteria

1. the next step remains narrower than direct host-runtime implementation
