Generated Scene Parameter Default Semantics Hardening Report

Scope

Executed the first reusable slice defined by 2026-04-20-generated-scene-parameter-default-semantics-hardening-plan.md.

Bounded scope:

• source-side recovery of default period semantics for parameterized monthly/weekly scenes
• generator-side preservation of recovered default strategy in param metadata
• route-local validation on the sweep-030-scene anchor

Out of scope:

• runtime resolver logic changes
• materialized skill refresh under examples/
• 102-scene rematerialization
• validation refresh

Outcome

This route now preserves source-derived default period semantics in generated parameter metadata.

The first reusable slice is closed for the route anchor:

• extract_deterministic_scene_facts(...) now emits period_default_strategy
• line-loss style month/week source evidence recovers lineloss_page_semantics
• generated month_week_period params now write resolver_config.default_strategy
• real sweep-030-scene generation writes default_strategy = "lineloss_page_semantics" into scene.toml

Files Changed

• src/generated_scene/analyzer.rs
• src/generated_scene/generator.rs
• tests/scene_generator_test.rs

Verification

Passed:

cargo test --test scene_generator_test analyzer_recovers_lineloss_period_default_strategy_from_source -- --nocapture
cargo test --test scene_generator_test generator_writes_real_sweep_030_org_dictionary_from_embedded_source -- --nocapture
cargo test --test scene_generator_modes_test -- --nocapture

Route-Local Notes

• The route preserves generation metadata only; runtime period resolution logic was not modified here.
• The first slice is intentionally limited to the recovered line-loss page semantics pattern.
• Existing repository warnings remain unchanged, including dead_code warnings in callback-host/openxml code and an existing unreachable_code warning in tests/scene_generator_test.rs.
