BKU012 / EVIDENCE FRESHNESS
Reverify the source. Do not rewrite the history.
The queue separates source maintenance from claim mutation. Current records stay scheduled, blocked records explain what evidence is absent, and scope-review-needed records stay identity questions rather than fabricated stale or conflicting claims.
FRESHNESS BOUNDARY
A queue state describes evidence maintenance only. It does not say a product is compatible, recommended, purchasable, correctly installed or safe to ride.

01 / QUEUE
Every maintenance row points to an exact evidence or field identity.
No record is marked due merely to demonstrate the state. The current 90-day field window places the selected current records ahead of future reverification dates; blocked and scope-review-needed are separate maintenance states.

02 / REVERIFICATION WORKFLOW
Completed checks append events. They do not erase evidence history.
Reopen the exact manufacturer or institutional source already tied to the record.
Check whether the same exact field is still supported, changed, unavailable or scope-divergent.
Record the recheck in source-change history instead of overwriting the prior evidence row.
Freshness review never becomes a compatibility, purchase, service or safety verdict.
Three exact-source rechecks completed in BKU012
The exact 2020 page still supports the stored E5 frame, Claris 8-speed and 700x35 mm Roadsport fields.
The Shimano page still supports 12-speed, 11-34/36T, 42T capacity and the stored range fields.
The SRAM service record still supports 12-speed, Road Flattop D1/E1, PowerLock D1 and E-Bike Approved No.
03 / STATE DISCIPLINE
Zero due is different from zero maintenance.
The queue already identifies what is next without prematurely aging fresh records. Two scope warnings need identity review, and two unknown fields are blocked because the exact sources do not state the requested values.

NO FABRICATED AGING
The field lifecycle still contains 66 current assertions, 3 unknown states, 2 scope warnings, 0 stale and 0 conflicting. BKU012 adds maintenance scheduling beside those states rather than forcing a stale example.

The ICU-wide adapter preserves BKU’s local distinctions: blocked and scope-review-needed do not become stale, and freshness never becomes a compatibility, purchase, service, or safety verdict.
