G6 Host Bridge Workflow Plan

Date: 2026-04-18 Status: Initial implementation slice

Plan Intent

Start the G6 line after G1-E second-sample reuse has been validated.

This plan implements the first safe slice only: classification, evidence separation, readiness gates, and fail-closed behavior.

Phase 0: Boundary Freeze

Tasks:

1. keep 电能表现场检验完成率指标报表 as the P0 boundary sample
2. define the repo-local representative fixture
3. keep G6 separate from G1, G1-E, G3, G7, and G8

Deliverables:

1. G6 design doc
2. G6 plan doc
3. repo-local representative fixture

Acceptance criteria:

1. G6 is no longer discussed as a G1 candidate
2. G6 is not treated as a generic localhost-pollution case

Phase 1: Analyzer Classification

Tasks:

1. add host_bridge_workflow as a workflow archetype
2. detect explicit host bridge actions
3. keep localhost:* as supporting host-runtime evidence
4. ensure explicit host bridge signals outrank G1-E
5. ensure ordinary localhost export noise does not become G6

Acceptance criteria:

1. g6_host_bridge_workflow fixture classifies as host_bridge_workflow
2. bootstrap_localhost_pollution remains a non-G6 business scene

Phase 2: Fail-Closed Gate

Tasks:

1. add readiness risks for missing or unsupported G6 contract
2. add g6_host_bridge_detected
3. add g6_fail_closed
4. block generation before runnable output

Acceptance criteria:

1. G6 generation returns a controlled error
2. error message includes host_bridge_workflow
3. no pseudo-runnable skill is produced

Phase 3: Regression

Tasks:

1. run scene generator regression
2. run family regression
3. run family policy regression
4. run canonical regression

Acceptance criteria:

1. all target regressions pass
2. no G1-E/G3/G2 behavior regresses

Next Step

After this safe G6 slice, continue to G7 多接口盘点汇总型 boundary assessment unless G6 runtime implementation becomes the selected priority.
