G2-D Prediction Compute Report

Status: Completed Date: 2026-04-18 Plan: 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.
