# AD-566f Qualification to Skill Bridge Build Report

**Date:** 2026-04-30
**Status:** Complete
**Prompt:** `prompts/ad-566f-qualification-skill-bridge.md`

## Summary

Implemented `QualificationSkillBridge` to connect qualification test outcomes to skill proficiency updates. Passing a mapped qualification with a sufficient score advances the matching skill by one `ProficiencyLevel` through `AgentSkillService.update_proficiency()`, records an in-memory `SkillAdvancement`, and leaves unmapped, failed, below-threshold, missing-skill, or max-level outcomes unchanged.

`QualificationStore`, `AgentSkillService`, qualification execution, proficiency decay, `ProficiencyLevel`, automatic test triggering, and persistence for advancement history were not changed.

## Files Changed

- `src/probos/cognitive/qual_skill_bridge.py`
  - Added `SkillAdvancement`, `DEFAULT_SCORE_THRESHOLDS`, and `QualificationSkillBridge`.
- `src/probos/runtime.py`
  - Wired `QualificationSkillBridge` after `skill_service` assignment when `_qualification_store` is available.
  - Registered the prompt's three default qualification-test mappings.
- `tests/test_ad566f_qual_skill_bridge.py`
  - Added 7 focused bridge tests.
- `PROGRESS.md`, `docs/development/roadmap.md`
  - Updated AD-566f tracking.

## Sections Implemented

- `### Section 1: Create QualificationSkillBridge`
  - Implemented in `src/probos/cognitive/qual_skill_bridge.py`.
- `### Section 2: Wire bridge in startup`
  - Implemented in `src/probos/runtime.py`.
- `## Tests`
  - Implemented in `tests/test_ad566f_qual_skill_bridge.py`.
- `## Tracking`
  - Updated `PROGRESS.md`, `docs/development/roadmap.md`, and this build report.

## Post-Build Section Audit

- `### Section 1: Create QualificationSkillBridge` — complete; bridge, mappings, thresholds, advancement processing, and history API exist.
- `### Section 2: Wire bridge in startup` — complete; runtime initializes the bridge after `self.skill_service = comm.skill_service` when `_qualification_store` exists.
- `## Tests` — complete; 7 focused tests added.
- `## Tracking` — complete; tracker and build report updates added.

## Tests

- `d:/ProbOS/.venv/Scripts/pytest.exe tests/test_ad566f_qual_skill_bridge.py -v -n 0`
  - Result: 7 passed.
- `d:/ProbOS/.venv/Scripts/pytest.exe tests/test_skill_framework.py tests/test_runtime_skill_routing.py tests/test_ontology_skills.py -v -n 0`
  - Result: 46 passed, 1 warning.
- `d:/ProbOS/.venv/Scripts/pytest.exe tests/ -q -n 4 --dist=loadfile`
  - Result: 10103 passed, 17 skipped.

## Deviations

- Used `AgentSkillService | None` behind a `TYPE_CHECKING` import on the bridge constructor per approved re-review recommendation while preserving runtime behavior.
