# Deterministic Keyword Scoring Refinement Design

> Date: 2026-04-20
> Parent Plan: `2026-04-20-scene-skill-102-deterministic-invocation-readiness-plan.md`

## Intent

Resolve the 9 deterministic dispatch ambiguity gaps found after normalizing the final materialized scene skills for `。。。` invocation.

The previous readiness pass proved that 92 complete packages can be selected by full-scene-name samples, but 9 scenes collide because generated include keywords are too broad for current score rules.

## Fixed Gap Set

1. `sweep-026-scene / 县区公司故障明细`
2. `sweep-034-scene / 售电收入日统计排程预测`
3. `sweep-037-scene / 嘉峪关可靠性分析报告`
4. `sweep-038-scene / 嘉峪关周报`
5. `sweep-039-scene / 嘉峪关故障明细`
6. `sweep-040-scene / 嘉峪关日报`
7. `sweep-041-scene / 嘉峪关月报`
8. `sweep-044-scene / 国网金昌供电公司指挥中心生产例会报告`
9. `sweep-045-scene / 国网金昌供电公司营商环境周例会报告`

## Scope

Allowed:

1. Refine deterministic include/exclude keywords for the fixed 9 scenes and direct collision partners when needed.
2. Run dispatch dry-run checks without browser execution.
3. Publish refinement decisions and readiness delta.

Forbidden:

1. Do not execute browser scripts.
2. Do not repair `sweep-012-scene`.
3. Do not change generated scripts.
4. Do not update official execution board.
5. Do not modify runtime dispatch code unless this design is superseded by a separate runtime-scoring implementation plan.

## Strategy

Prefer manifest-level disambiguation first:

1. keep full scene names as primary keywords;
2. remove overly broad standalone tokens from colliding scenes where they create ties;
3. add distinctive phrase keywords only when present in the scene name;
4. use `exclude_keywords` only for direct mutually exclusive cases.

Runtime scoring changes are out of scope for this plan unless manifest refinement cannot make all 9 gaps uniquely selectable.

## Completion Criteria

1. All 9 fixed gaps have final decisions.
2. Full-scene-name dispatch dry-run uniquely selects the expected scene for each fixed gap.
3. No new ambiguity is introduced for the complete 101-package set.
4. `sweep-012-scene` remains excluded.
