# G6 Real-Sample Entry Preparation And Bounded Execution Design

> Date: 2026-04-19
> Status: Draft
> Replaces Further G6 Micro-Planning: use this design as the single surviving `G6` design reference

## 1. Intent

This design replaces the previous over-split `G6` micro-planning chain with one implementation-oriented bounded design.

The target is:

`G6 real-sample entry preparation and bounded execution`

## 2. Why This Redesign Exists

The prior `G6` work was split too finely into:

1. prerequisites
2. execution semantics
3. callback semantics
4. callback-state verification
5. entry readiness
6. entry gate

That chain produced useful conclusions, but it also created planning recursion.

This redesign stops that recursion.

The older `G6` planning documents are now treated only as input material, not as separate execution tracks.

## 3. Preserved Inputs

The only conclusions preserved from the earlier `G6` planning chain are:

1. `G6` already has classification, family preservation, and a minimum runtime-contract shape
2. the remaining pressure is `host bridge real execution semantics`
3. callback completion states are already explicit:
   - `blocked`
   - `error`
   - `partial`
   - `ok`
4. the future `G6` fail-close reasons are already explicit:
   - `g6_bridge_invocation_semantics_missing`
   - `g6_callback_completion_semantics_missing`
   - `g6_callback_state_targets_missing`

No further `G6` semantic sub-plans should be opened for the same topic.

## 4. Scope Boundary

This design is limited to one bounded `G6` mainline preparation-and-execution slice.

It may include:

1. freezing one final `G6` entry gate
2. implementing one minimum host-bridge execution seam
3. running one fixed `G6` real sample
4. writing back one bounded validation result

It must not include:

1. opening more `G6` semantic sub-plans
2. reopening `G7`
3. opening `G8`
4. opening `G4 / G5`
5. broad host-runtime platform redesign
6. multi-sample `G6` family expansion

## 5. Fixed Target

This design allows only one `G6` fixed real-sample anchor.

The exact sample must remain the existing `G6` representative real sample already referenced by current boundary-family materials.

No second `G6` real sample may be introduced under this design.

## 6. Target Outcome

The bounded target outcome is only one of two states:

1. `executed-pass`
2. `named mismatch`

The design explicitly rejects a third outcome of “write another semantic clarification plan”.

## 7. Stop Conditions

This redesign introduces hard stop conditions:

1. once the fixed `G6` real sample is executed, no new `G6` semantic sub-plan may be created
2. if the result is `mismatch`, only an implementation correction plan may follow
3. if the result is `executed-pass`, the `G6` line closes immediately

## 8. Execution Shape

The single surviving `G6` execution shape is:

1. freeze the final entry gate
2. implement the minimum host-bridge execution seam
3. run the fixed real sample once
4. update validation assets and close

## 9. Exit Condition

This design is complete when one bounded plan exists that:

1. freezes the final `G6` gate
2. moves directly into implementation
3. runs one fixed real sample
4. closes with `executed-pass` or `named mismatch`
