+# Scene Skill 102 Final Materialization Plan
+
+> Date: 2026-04-19
+> Parent Framework: `2026-04-19-scene-skill-102-full-coverage-framework-plan.md`
+> Parent Layer: final asset materialization before validation
+> Status: Draft
+
+## Plan Intent
+
+Generate and freeze a single canonical `102` skill package set for later static, mock, and production-like validation.
+
+This plan answers whether all 102 scenes have materialized skill assets, not just framework auto-pass status.
+
+## Fixed Inputs
+
+1. `tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json`
+2. `tests/fixtures/generated_scene/scene_skill_102_framework_closure_rollup_2026-04-19.json`
+3. scene source root: `D:/desk/智能体资料/全量业务场景/一平台场景`
+
+## Output Root
+
+`examples/scene_skill_102_final_materialization_2026-04-19`
+
+## Allowed Files
+
+1. `examples/scene_skill_102_final_materialization_2026-04-19/**`
+2. `tests/fixtures/generated_scene/scene_skill_102_final_materialization_manifest_2026-04-19.json`
+3. `tests/fixtures/generated_scene/scene_skill_102_final_materialization_failures_2026-04-19.json`
+4. `docs/superpowers/reports/2026-04-19-scene-skill-102-final-materialization-report.md`
+
+## Forbidden Files
+
+1. `src/generated_scene/analyzer.rs`
+2. `src/generated_scene/generator.rs`
+3. `src/generated_scene/ir.rs`
+4. `tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json`
+5. existing `examples/*` follow-up roots outside the output root
+
+## Phase 0: Freeze Materialization Boundary
+
+### Tasks
+
+1. Confirm framework rollup is `102 / 102`.
+2. Confirm materialization does not delete existing `examples/*`.
+3. Confirm this plan does not perform static/mock/production validation.
+
+### Acceptance Criteria
+
+1. Scope is materialization only.
+2. Output root is isolated.
+
+## Phase 1: Build Materialization Input Manifest
+
+### Tasks
+
+1. Load official board or fallback source-list assets.
+2. Produce exactly 102 materialization input rows.
+3. Validate unique scene ids.
+4. Resolve source directory for each scene.
+5. Sanitize manifest-only string fields for control characters.
+
+### Acceptance Criteria
+
+1. Input manifest has 102 rows.
+2. No missing source directory remains.
+3. No duplicate scene id remains.
+
+## Phase 2: Generate 102 Skill Packages
+
+### Tasks
+
+For each manifest row, run:
+
+```powershell
+cargo run --bin sg_scene_generate -- `
+  --source-dir "<sourceDir>" `
+  --scene-id "<sceneId>" `
+  --scene-name "<sceneName>" `
+  --scene-kind report_collection `
+  --output-root "D:/data/ideaSpace/rust/sgClaw/claw-new/examples/scene_skill_102_final_materialization_2026-04-19"
+```
+
+### Acceptance Criteria
+
+1. Every row is attempted.
+2. No single scene failure stops the full batch.
+3. stdout/stderr/result status are captured.
+
+## Phase 3: Verify Materialized Package Presence
+
+### Tasks
+
+For each scene, check:
+
+1. `SKILL.toml`
+2. `SKILL.md`
+3. `scene.toml`
+4. `references/generation-report.json`
+5. at least one script under `scripts/`
+
+### Acceptance Criteria
+
+1. All successful rows have required files.
+2. Failures are explicit in the failures asset.
+
+## Phase 4: Publish Manifest And Report
+
+### Tasks
+
+1. Publish final materialization manifest.
+2. Publish final materialization failures.
+3. Publish superpowers report.
+
+### Acceptance Criteria
+
+1. Manifest row count is 102.
+2. Report states generated count, failure count, readiness distribution, and next validation input.
+3. The report explicitly states that old `examples/*` roots were not cleaned.
+
+## Expected Delta
+
+No framework coverage delta. Expected asset delta is:
+
+1. `102` canonical final skill package rows;
+2. one stable manifest for later validation.
+
+## Stop Statement
+
+Stop after final materialization manifest, failures asset, and report are published. Do not start static, mock, or production validation under this plan.
