approve-hld

To formally approve a high-level design (HLD) document, you update its status to Approved and add a version history entry. This sign-off acts as a mandatory gate prior to creating downstream data model specifications and transformation mappings.

Approving an HLD still in draft status triggers pre-approval validation checks that prevent premature sign-off. The system enforces these checks to ensure unreviewed draft documents are not accidentally approved before downstream data engineering work begins.

HLD approval unlocks downstream data artifacts including data model specifications, transformation mappings, data quality checks, low-level designs, and implementation stories. This ensures all downstream data architecture workflows follow proper sign-off procedures.

Audit logging for HLD approval is handled by writing session memory notes that record the action for future reference. Additionally, the metadata table is modified via targeted edits to update Status, Last Modified fields, and Version History.

No, you cannot approve the same HLD multiple times because pre-approval validation checks detect duplicate approved statuses. This prevents redundant sign-offs and maintains accurate version history for your data architecture workflows.
