# Generated Scene Runtime Semantics Post-Refresh Residual Closure Report
Date: 2026-04-21
Plan:
- `docs/superpowers/plans/2026-04-21-generated-scene-runtime-semantics-post-refresh-residual-closure-plan.md`
## Scope
This closure handled only the two post-refresh residuals exposed by the 2026-04-21 validation refresh:
1. deterministic suffix regression in rematerialized `scene.toml`
2. invalid TOML generation for `sweep-078-scene`
No rematerialization refresh, validation refresh, pseudo-production execution, runtime change, service-console change, or board update was executed.
## Changes
### Deterministic suffix regression
`render_scene_toml` now emits:
```toml
suffix = "。。。"
```
instead of using the scene name as the deterministic suffix.
### TOML string escaping
`escape_toml` now escapes:
1. backslash
2. double quote
3. newline
4. carriage return
5. tab
6. remaining control characters
This prevents request mapping fields or other generated scalar strings from breaking TOML syntax when source evidence contains comments, embedded line breaks, or malformed text fragments.
## Files Changed
- `src/generated_scene/generator.rs`
- `tests/scene_generator_test.rs`
## Route-Local Asset
- `tests/fixtures/generated_scene/generated_scene_runtime_semantics_post_refresh_residual_closure_followup_2026-04-21.json`
## Validation
Passed:
```powershell
cargo test --test scene_generator_test generator_writes_real_sweep_030_org_dictionary_from_embedded_source -- --nocapture
cargo test --test scene_generator_test generator_escapes_request_mapping_fields_for_valid_toml -- --nocapture
```
The first test proves the generated `sweep-030-scene` `scene.toml` now preserves the hardened facts and emits `suffix = "。。。"`.
The second test proves the generated `sweep-078-scene` `scene.toml` parses as TOML after escaping.
## Residuals Not Closed Here
The `6` `local_doc_pipeline` rematerialization residuals were not addressed in this plan:
1. `sweep-025-scene`
2. `sweep-047-scene`
3. `sweep-050-scene`
4. `sweep-052-scene`
5. `sweep-062-scene`
6. `sweep-087-scene`
They require a separate bounded route if they remain in scope.
## Next Step
Rerun the runtime-semantics rematerialization execution plan, then rerun validation refresh against the newly generated bundle.
Do not proceed directly to pseudo-production from the previous 2026-04-21 refreshed bundle.
