# G7 Multi Endpoint Inventory First Slice Report

> Date: 2026-04-18
> Scope: `G7` classification and fail-closed safety slice

## Summary

The first `G7` implementation slice is complete.

This round added the `multi_endpoint_inventory` archetype and a repo-local representative fixture for the `计量资产库存统计` boundary family.

The result is intentionally fail-closed: `G7` can now be identified and prevented from falling back into `G1/G1-E`, but runnable aggregation is not implemented yet.

## Assets Updated

1. `src/generated_scene/ir.rs`
2. `src/generated_scene/analyzer.rs`
3. `src/generated_scene/generator.rs`
4. `tests/fixtures/generated_scene/g7_multi_endpoint_inventory/index.html`
5. `tests/scene_generator_test.rs`

## Behavioral Result

The representative fixture validates:

1. `workflowArchetype = multi_endpoint_inventory`
2. inventory endpoint count is at least five
3. inventory endpoint names include `assetStatsQueryMeter`
4. inventory endpoint names include `assetStatsQueryJlGnModule`
5. generation fails closed with `multi_endpoint_inventory`

## Validation

Executed:

```powershell
cargo test --test scene_generator_test -- --nocapture
cargo test --test scene_generator_p1_family_test -- --nocapture
cargo test --test scene_generator_family_policy_test -- --nocapture
cargo test --test scene_generator_canonical_test -- --nocapture
```

All target regressions passed.

## Result

`G7` is now safely separated from `G1/G1-E` at classification time.

The family remains fail-closed until a formal multi-endpoint inventory aggregation contract is implemented.
