# G2-D Prediction Compute Report

> Status: Completed
> Date: 2026-04-18
> Plan: [2026-04-17-scene-skill-60-to-90-roadmap-plan.md](D:/data/ideaSpace/rust/sgClaw/claw-new/docs/superpowers/plans/2026-04-17-scene-skill-60-to-90-roadmap-plan.md)

## Intent

Within the existing `G2` line-loss family contract, promote the last deferred `G2-D` candidate into a repo-local reusable expansion baseline without crossing into new runtime families or login/transport scope.

## Scope

This slice only adds:

1. a deterministic `G2-D` fixture
2. subtype classification for `g2_d_prediction_compute`
3. a minimal reusable `prediction` mode recovery path
4. regression coverage
5. Track D / Track E asset synchronization

It does not introduce:

1. file-input runtime support
2. local compute engine execution
3. new family boundaries outside `G2`

## Delivered

1. Added fixture: `tests/fixtures/generated_scene/g2_prediction_compute`
2. Added analyzer subtype: `G2FamilyVariant::G2D`
3. Added generator mode recovery: `prediction`
4. Added deterministic and generation regressions
5. Promoted `predicted_compute_variant` into the `G2` batch expansion baseline
6. Synchronized candidate batch, family manifest/results, ledger status overlay, and roadmap execution status

## Acceptance

1. `G2-D` now compiles through the existing `multi_mode_request` family path
2. generated default mode is `prediction`
3. generated report contains `lineId`, `lineLossRate`, and `powerLoss`
4. Track A no longer keeps `deferred-g2-d-candidate` as an outstanding item

## Notes

This promotion stays inside the roadmap boundary because it only consumes the remaining queued/deferred `G2` family item and does not open new archetype scope.
