Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to The PR prevents delegated credential re-mint from being redirected through a broker-shaped relay binary while preserving the intended refresh and Cloud fallback behavior; no actionable merge-blocking risk remains after normal checks.

When delegated refresh fails because the canonical Cloud session is missing or its refresh token has expired, automatic retries cannot restore the credentials without a login; malformed or insufficient scopes likewise require human intervention. Replacing the persisted stall reason with a blanket “relayfile will retry” hides that required action, so an affected mount can remain read-only indefinitely while relayfile status suggests it will self-heal. Preserve the underlying re-mint cause/remedy here, or reserve this retry message for genuinely transient failures.
Useful? React with 👍 / 👎.
The previous commit replaced "re-authenticate" with a single fixed "relayfile will retry" sentence. That trades one blanket message for its mirror image: a fully expired Cloud session, or scopes Cloud refuses to mint, cannot be restored by retrying, so promising self-healing leaves the mount read-only indefinitely while `relayfile status` claims it is recovering. Derive the stall reason from the error that caused it. Transient re-mint failures name the underlying error and state that relayfile will retry; expired-session and scope failures say plainly that automatic re-mint cannot recover them and what a human has to do. Keep the recorded cause current while the mount stays degraded, so a stall that begins transient and later becomes unrecoverable stops advertising a retry. Also drop the local username and workstation path from the trajectory record this branch added, matching the repository identifier the other records use.
