BKU010 / APPEND-ONLY EVIDENCE

Resolve the row. Keep the history.

BKU010 records what happened after a missing or unknown requirement was researched. A later exact source may establish one narrow requirement, but the earlier audit row remains historical evidence and the wider bicycle system receives no automatic verdict.

HISTORY LOCK

R000009 remains 11 missing + 3 unknown. BKU010 writes resolution events beside that snapshot; it rewrites 0 historical rows.

01 / LEDGER

Events append. They do not erase.

Two new exact SRAM evidence records establish two narrow XPLR research requirements. Four additional review events explicitly preserve unresolved states.

Each event names its gap path, evidence IDs, claim scope, and state after the event.

02 / SESSION HANDOFF

Carry the open questions forward.

Choose one of the three audited research sets. The handoff summarizes later evidence events and unresolved questions without telling the visitor what to buy, install, adjust or ride.

NO TRANSITIVE INFERENCE

A↔B and B↔C never creates A↔C. A resolution event establishes only the named requirement at its cited scope.

03 / PROVENANCE

One narrow resolution does not close neighboring gaps.

RD-RIV1-E-D1 ↔ CS-XG-1251-D1

Resolution event bku.resolution_event.001 points to exact SRAM compatibility-map evidence. It does not certify the hub, chain, installation context, or the rest of the bicycle.

Exact hub / wheel identity

The XDR driver-body evidence still leaves the surrounding implementation unidentified. That historical missing requirement remains open in the current overlay.

04 / AUTHORITY GATE

Research handoff ends before prescription.

NO HISTORY REWRITEOriginal missing/unknown rows remain immutable.

NO PROCEDURE / TORQUEExact manufacturer documentation remains authoritative.

NO SYSTEM VERDICTResolved requirements do not certify compatibility, completeness or safety.
