# G6 Host-Bridge Callback Semantics Report > Date: 2026-04-19 > Plan: [2026-04-19-g6-host-bridge-callback-semantics-plan.md](D:/data/ideaSpace/rust/sgClaw/claw-new/docs/superpowers/plans/2026-04-19-g6-host-bridge-callback-semantics-plan.md) ## Result This bounded slice defines four explicit callback completion states: 1. `ok` 2. `partial` 3. `blocked` 4. `error` ## What Was Formalized The current generated `G6` runtime shape already encodes a state priority: 1. `blocked` 2. `error` 3. `partial` 4. `ok` This slice formalizes that priority instead of leaving it as implicit code behavior. ## Explicit Non-Goal This slice does not broaden into: 1. host-runtime implementation 2. `G6` real-sample execution 3. `G8` work ## Follow-Up The next bounded step is: 1. `G6 host-bridge callback state verification`
