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
