> Upstream Spec: [2026-04-19-g6-host-bridge-prerequisites-design.md](D:/data/ideaSpace/rust/sgClaw/claw-new/docs/superpowers/specs/2026-04-19-g6-host-bridge-prerequisites-design.md)

## Plan Intent

This plan executes one bounded next slice:

`G6 host-bridge prerequisites`

## Scope Guardrails

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

## Workstreams

1. `WS1` Freeze the G6 prerequisite boundary
2. `WS2` Isolate the minimum blocked host-bridge capability
3. `WS3` Publish one bounded prerequisite result

## Phase 0: Freeze the Boundary

### Objective

Lock the plan to `G6` prerequisite scoping only.

### Tasks

1. freeze `G6` as the only target
2. freeze `G6` real-sample execution as out of scope

### Acceptance Criteria

1. no other boundary family is touched under this plan

## Phase 1: Isolate the Minimum Blocked Capability

### Objective

Reduce `G6` prerequisite pressure to the smallest explicit capability gap.

### Tasks

1. restate the current `G6` hold condition
2. isolate the minimum host-bridge execution semantic still missing
3. keep that capability separate from broader runtime-platform work

### Acceptance Criteria

1. the blocked capability is explicit and bounded

## Phase 2: Publish the Bounded Result

### Objective

Turn the isolated prerequisite into one bounded next artifact.

### Tasks

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

### Acceptance Criteria

1. the next step is narrower than broad host-runtime implementation
