## Plan Intent

This plan executes one bounded next slice:

`G6 host-bridge callback state verification`

## 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 callback-state verification scope
2. `WS2` Define verification targets for `ok/partial/blocked/error`
3. `WS3` Publish one bounded verification result

## Phase 0: Freeze the Boundary

### Objective

Lock the plan to callback-state verification 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 Verification Targets

### Objective

Turn the explicit callback states into bounded verification targets.

### Tasks

1. define verification target for `ok`
2. define verification target for `partial`
3. define verification target for `blocked`
4. define verification target for `error`

### Acceptance Criteria

1. callback verification targets are explicit and bounded

## Phase 2: Publish the Bounded Result

### Objective

Turn the callback-state verification model into one bounded next artifact.

### Tasks

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

### Acceptance Criteria

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