Goal

Capture enough context for recall without storing repetitive frames or exhausting resources.

Requirements

Configurable interval-based capture.
Trigger capture on meaningful active-window or workspace changes.
Perceptual image hashing and metadata comparison before expensive OCR/model work.
Coalesce near-duplicate frames into duration spans.
Bounded queues, CPU/memory budgets, and configurable drop policy.
Suspend or reduce capture under overload rather than accumulating stale work.

Acceptance criteria

Identical and near-identical frames do not produce redundant stored records.
Window changes can trigger immediate capture while rapid focus churn is debounced.
Load tests demonstrate bounded memory use.
Deduplication never reuses data across different capture sessions or privacy-policy contexts.
