Research direction

Start in crates/registry-bregctl/src/lib.rs at the usage.invalid path in main, and compare the existing value-free diagnostic pattern used by evidencectl and the caseworkctl/schedulingctl fixes. Add a bregctl test using a sentinel rejected for --operator-reference, then verify the sentinel appears in neither stdout nor stderr for the human and JSON error paths.

Description

area:breg bug criticality:p3 triage:needs-implementation

bregctl builds its usage-error diagnostic from clap's rendered error (crates/registry-bregctl/src/lib.rs, the usage.invalid path in main), in both human and JSON output. Clap's rendering quotes the rejected value, so a refused or misspelled --operator-reference=VALUE is written back to stdout or stderr in clear. Everywhere else, that value is kept only as a keyed hash.

Exposure is limited to the operator's own terminal and anything capturing its output, such as CI logs. It is still a gap in data minimization.

evidencectl on main already uses a fixed message. The WP3 Casework and Scheduling PR fixes caseworkctl and schedulingctl by building the message from the error kind and the argument name, while keeping our own value-free validator reasons.

Fix: apply the same pattern in bregctl. Add a test that passes a sentinel value clap rejects for --operator-reference and asserts the sentinel appears in neither stdout nor stderr.

Planned with the bregctl half of #1412, which moves bregctl onto the shared ctl report contract.
