# G8 Local Document Pipeline First Slice Report

> Date: 2026-04-18
> Scope: `G8` classification and fail-closed safety slice

## Summary

The first `G8` implementation slice is complete.

This round added the `local_doc_pipeline` archetype and a repo-local representative fixture for the `95598供电服务月报` boundary family.

The result is intentionally fail-closed: `G8` can now be identified and prevented from falling back into `G1/G1-E/G6`, but runnable local storage, SQL analysis, and document-generation orchestration 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/g8_local_doc_pipeline/index.html`
5. `tests/scene_generator_test.rs`

## Behavioral Result

The representative fixture validates:

1. `workflowArchetype = local_doc_pipeline`
2. localhost dependency evidence includes `localhost:13313`
3. local pipeline actions include `definedSqlQuery`
4. local pipeline actions include `docExport`
5. local pipeline actions include `selectData`
6. generation fails closed with `local_doc_pipeline`

## Boundary Correction

The first test run showed that `G8` could be captured by `G6` because the fixture also contains host bridge actions.

The classifier now prioritizes local document pipeline evidence over generic host bridge evidence. This preserves the intended family boundary:

1. `G6`: host bridge driven query progression
2. `G8`: local persistence, SQL analysis, and document production after data capture

## 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

`G8` is now safely separated from `G1/G1-E/G6` at classification time.

The family remains fail-closed until a formal local document pipeline runtime contract is implemented.
