/as:schedule-quantity-reconcile — Reconcile sourced quantities

Before acting, read the host contract and declaration (skill:schedule-quantity-reconcile), using its profiles from the catalog. No source or write access is implied.

Use the host adapter and available native tools or ordinary task-specific code. Operation names identify semantic procedures, not installed functions. No Arch Studio runner, package installation or executable reconstruction is required. Existing exact authorization persists; ask only for material missing information or permission.

Input: two source-identified quantity snapshots and explicit building/floor/phase/revision scope. Output: a read-only comparison, not an authoritative merged schedule. Project instructions apply when bound to a project; one-off comparison does not initialize or adopt records.
