Research direction

The issue mentions the file crates/registry-breg/src/startup.rs where binding checks for candidate and rehearsal flows currently report a generic Binding refusal. Start by examining the #1364 fix to understand how bregctl apply reports mismatches with the differing runtime key (e.g., identity.databaseId). Then, locate the binding checks in the startup.rs file and update them to use the same field-naming logic, ensuring no values are exposed. Run any existing tests related to binding refusals to verify the changes.

Written by the indexing model from the issue text.

Description

area:breg enhancement

Gap

The #1364 fix makes bregctl apply report a binding mismatch as apply.package.binding_mismatch, with the differing runtime key as the diagnostic path (for example identity.databaseId or package.activeSequence) and no values. The binding checks in crates/registry-breg/src/startup.rs for candidate and rehearsal flows still report the generic Binding refusal, so an operator there still can't tell which field differs.

Request

Route those checks through the same field-naming mismatch so every binding refusal names the key, and never the values.

Follow-up from #1364.
