Execute this scoped task fully in the current part project: Complete the finite IO-terminal migration. Treat fresh state as continuation baseline, initialize cumulative accounting prior writes=5 and prior mutation calls/batches=1, preserve continuation-start initial mismatch metric=5 exactly. There are 676 Terminal components and exactly 280 targets with exact designator prefix IO_ (exclude contains-only like VCCINT_IO_*). Desired state by natural-sort rank of target designators: Terminal Order unique 1..280; Pin Orientation Right; Pin Group User I/O; Section User I/O. Preserve unrelated properties and non-targets. Concurrent writers are expected: repeatedly fresh direct snapshot/audit until one simultaneous fresh all-676 snapshot clean. Before each sequential mutation batch <=10 targets, immediate full-property guard-read exactly those terminals and only write still mismatched. Track actual terminal writes and mutation calls cumulatively including prior 5/1, and audit passes. Verify full 676 fresh snapshot target count 280 mismatches 0, then focused all 280 fresh full-property clean orders 1..280 exact. Locate existing project file whose URL short-id begins e1 even if renamed; do not create file; preserve content and append concise audit section with exact metrics and verification. Update only that existing file. Return final title/slug/short-id/link and metrics. Do not stop due concurrency.
