# BF-247 TieredKnowledgeLoader dag_summary Type Build Report

**Date:** 2026-04-29
**Status:** Complete
**Prompt:** `prompts/bf-247-tiered-knowledge-dag-summary-type.md`
**Builder:** GitHub Copilot

## Files Changed

- `tests/test_ad585_tiered_knowledge.py`
  - Added 4 focused tests for dict `dag_summary` handling.
- `PROGRESS.md`
  - Added BF-247 CLOSED tracking entry.
- `docs/development/roadmap.md`
  - Marked BF-247 Closed.
- `prompts/build-reports/bf-247-tiered-knowledge-dag-summary-type-build.md`
  - Added this build report.

## Sections Implemented

- `## Status` - confirmed production fix was already applied in `8be47d5`; no production code changes made.
- `## Problem (for context)` - verified coverage targets the dict `dag_summary` regression described by the prompt.
- `## What Was Fixed` - no code changes required; added tests for the fixed `_load_category` and `load_on_demand` behavior.
- `## Remaining Work: Add Tests` - implemented all 4 requested tests in `tests/test_ad585_tiered_knowledge.py`.
- `## What This Does NOT Change` - preserved all listed boundaries: no dataclass, store, CognitiveAgent, dreaming, or guided reminiscence changes.
- `## Tracking` - updated `PROGRESS.md` and `docs/development/roadmap.md`.
- `## Acceptance Criteria` - targeted BF-247 test file passed with all 36 tests.

## Post-Build Section Audit

- `## Status` - covered by scope: production code was not modified.
- `## Problem (for context)` - covered by regression tests exercising dict `dag_summary` inputs.
- `## What Was Fixed` - covered by tests against the already-fixed code paths.
- `## Remaining Work: Add Tests` - all four named tests were added.
- `## What This Does NOT Change` - confirmed by changed-file list.
- `## Tracking` - trackers updated.
- `## Acceptance Criteria` - test command passed; full serial suite deferred to final sweep gate per 2026-04-29 revised execution instruction.

## Tests

- `d:/ProbOS/.venv/Scripts/pytest.exe tests/test_ad585_tiered_knowledge.py -v -n 0`
  - Result: 36 passed.

## Deviations from Prompt

- None. Full-suite `-n 0` is being reserved for the final sweep gate per the revised execution instruction because xdist is known to produce environmental failures and serial full-suite runs are slow.
