What problem does it solve? Completed feature work often leaves durable decisions and knowledge trapped in archived folders, while living ledgers that teams rely on for current operational truth become stale. This Skill moves durable knowledge from completed, published feature archives into the correct ledgers without erasing the permanent feature history. ## Core Features & Use Cases - Promotion Planning and Apply: Builds a promotion plan separating direct ledger updates, new ledger entries, deferred items, and blocked items, with a dry-run default in headless mode unless --apply is passed. - Provenance Preservation: Adds source_feature references and stable IDs to every promoted entry so ledger content stays traceable to its feature archive. - Blocking and Advisory Classification: Flags missing stable IDs, conflicting parent references, duplicate identities, and blocked Lens preflight status before any write occurs. - Use Case: After closing out a feature in docs/features, run a promotion review to move its durable decisions into the relevant service ledger and receive a report with an APPLIED, PLANNED, PARTIAL, or BLOCKED verdict. ## Quick Start Ask the assistant to run lens ledger promotion for the completed feature folder and produce a promotion plan and report.
