# 102 Scene Ledger Alignment Report

## Scope

This round does not attempt full `102`-scene migration.

It freezes the workbook snapshot `docs/2026-04-18-102-scenes-validation-overview.xlsx` into repo-local assets so the current code-backed family baseline can be compared against a concrete ledger snapshot.

## Delivered

Added:

1. `tests/fixtures/generated_scene/scene_ledger_snapshot_2026-04-18.json`
2. `tests/scene_ledger_snapshot_test.rs`

## Snapshot Facts

From the workbook snapshot generated at `2026-04-18 16:48:05`:

1. total scenes: `102`
2. validated scenes: `9`
3. not yet validated scenes: `93`
4. passed real sample: `1`
5. failed real samples: `3`
6. fail-closed scenes: `2`
7. reassigned boundary scenes: `3`

## Alignment With Current Family Assets

The frozen ledger snapshot now explicitly aligns with the repo-local family baseline on these points:

1. `G1-E`
   - `高低压新增报装容量月度统计表` is the only passed real sample in the snapshot
2. `G2`
   - three validated line-loss samples remain recorded as first-round failed runs
3. `G6`
   - `电能表现场检验完成率指标报表` is recorded as a reassigned boundary scene
4. `G7`
   - `计量资产库存统计` is recorded as a reassigned boundary scene
5. `G8`
   - `95598供电服务月报` is recorded as a reassigned boundary scene

## Interpretation

The workbook remains a mid-run ledger snapshot, not the final latest state of same-day markdown execution.

That distinction is now preserved in repo assets:

1. ledger snapshot = frozen workbook state
2. family assets = current code-backed baseline
3. markdown reports = later execution progress on the same day

## Validation

Passed:

- `cargo test --test scene_ledger_snapshot_test -- --nocapture`

## Outcome

Track D / Track E now have a repo-local bridge between:

1. family-level code-backed baselines
2. the original `102`-scene workbook snapshot

This gives the next expansion round a stable ledger anchor without forcing full Excel-driven workflow into the compiler path.
