Subject: [PATCH] Record the reconciled backend composition tip (da1d9fa)

Why: the L1 backend pin advances to the reconciled tip (association/
explanation tests reconciled to the narrowed role model, catalog test
brace restored, full filtered suites green).

Impact: backend gitlink pin.

Refs: PR #634.
