Side A implements a concrete user-facing capability by making pinned child-group icons submit the existing `set_garden_pin` unpin flow, wiring the required navigation path through rendering, updating styles, and adding comprehensive browser tests that verify unpin behavior from the ranked list and HUD. Side B is largely a CLI command reshaping and documentation update (`ingest`/`forum` command structure, help text, test adjustments) with limited underlying functionality beyond reorganizing the interface.
