FAILED / mutation unattempted. The mandatory seven-page preflight gate passed, but the requested 280-component exact mutation could not be safely materialized through the available explicit per-designator property mutation interface within this run. To avoid a partial or incorrectly ranked migration, no component-property mutation was issued.

Exact worklist filter: case-sensitive IO_.

Exact preflight read parameters on every page: mode=full, filter_prefix=IO_, components included, properties included, pins included, nets omitted, limit=40; offsets 0,40,80,120,160,200,240.

Union: 280 records and 280 unique exact designators; gate PASS.

No schematic/component mutation was made. No properties, including Pin Description or unrelated properties, were touched by this run.

Natural-sort the 280 exact designators numeric-aware with lexical tie-break and assign ranks 1..280; set only Terminal Order, Pin Group, Section, Pin Orientation, conditionally Description, and conditionally Pin Type exactly as requested. Preserve Pin Description and every unrelated property.

Because no target mutation was issued, the required post-mutation seven-page verification and target mismatch/bucket certification are unattempted rather than represented as a successful migration. Preflight evidence above is the only certification from this run.

The available property mutation operation requires an explicit per-component payload. This run did not safely produce and validate the full numeric-aware rank-to-designator mapping plus exact conditional values for all 280 components. Issuing a partial batch would violate the finite all-worklist request and could leave incorrect Terminal Order ranks, so execution stopped before the first primary mutation.
