i1..i5 are emitted by an `i%d=` loop rather than literal per-key sendf calls,
which made a grep-based audit conclude they were missing from the get path.
Live IpcSet -> IpcGet round-trip proves all 16 are reported; unset I-slots
(i2/i4) stay absent. See SPECS/TASKS/031-AWG_PARITY_AUDIT_ADVANCED_SECURITY.
