Implement AAII source-validation loader and synthetic fixtures

Objective

Implement AAII source-validation loader and synthetic fixtures.

Notes: Implemented research/aaii_source.py source-agnostic CSV validator and synthetic fixtures/tests: strict month labels, [0,100] allocation range, July 2006+ uniqueness/continuity, SHA-256 and provenance metadata, conservative following-month release floor with injectable exchange calendar. No production observations added; documented non-UI safety-boundary exception.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t332. Summary reconstructed from research/findings/task-history.json entry and git history. Uncertain fields: detailed approach, exact file list, and metrics beyond the task note.

Files / code / data changed

• No commit SHA confidently associated with t332 in sampled log [reconstructed — uncertain].
• Task-history entry: research/findings/task-history.json#t332

Results

Task note: Implemented research/aaii_source.py source-agnostic CSV validator and synthetic fixtures/tests: strict month labels, [0,100] allocation range, July 2006+ uniqueness/continuity, SHA-256 and provenance metadata, conservative following-month release floor with injectable exchange calendar. No production observations added; documented non-UI safety-boundary exception. [reconstructed — uncertain] No quantitative tables recovered for this entry; see git diff and task-history for grounds.

Conclusions

[reconstructed — uncertain] Outcome inferred from status done and task note.
