Goal

Retrieve the right encrypted records for natural-language questions while preserving traceability.

Requirements

Parse explicit and relative time ranges using the user’s configured timezone.
Combine time, application, workspace, metadata, keyword, and semantic filters.
Decrypt only the minimum selected records for the duration of a query.
Rank results with source timestamps and confidence.
Carry record IDs, capture timestamps, metadata provenance, and redaction status into downstream answers.
Enforce query-time policy restrictions and remote-provider eligibility.

Acceptance criteria

Queries such as “What was I doing Saturday?” resolve to the correct absolute date range.
Results can be filtered by application, workspace, and time.
Every returned passage maps to an existing encrypted source record.
Decrypted query working sets are discarded after completion or cancellation.
