📝 WalkthroughWalkthroughThe CLI now classifies delegated credential failures, preserves Cloud re-mint errors, and reports the current degraded-state cause. Tests cover refresh paths, broker-shaped binaries, re-mint behavior, and failure classification. Changelog and trajectory records document the work. ChangesDelegated credential recovery
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to Delegated mount recovery can continue showing an outdated needs-human cause after a later transient re-mint failure, which may mislead operators about whether retrying can help. The change is otherwise mergeable with explicit owner follow-up to refresh the degraded cause after every failed recovery attempt. Sequence Diagram(s)sequenceDiagram

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.

Do not merge — two independent P1s converge on the same defect, and it is the one this PR exists to fixAll 8 CI checks are green. Four inline findings from three reviewers, and the two P1s agree from different angles, which makes them credible rather than noise. The irony, stated plainlyThis PR exists because an error message misdiagnosed a healthy system. The old text said "re-authenticate with The fix introduces a new misdiagnosis in the opposite direction.
So the old message told an operator to act when no action was needed; the new one tells them to wait when action is required. Both are wrong, in opposite directions. A message that says "retrying" while a mount is permanently degraded is the worse of the two, because nothing prompts anyone to look. The other two
What is genuinely good here, and should survive the revisionVerified independently:
What is neededAddress both P1s — the classification must distinguish retryable from requires-human-action, and the message must say which. That is the whole point of the change. The P2 and the trajectory path are cheap and worth doing in the same pass.

A session supplied through CLOUD_API_* cannot run an interactive login, but the refresh-rejected branch returned ErrCloudRefreshExpired unmodified, whose text prescribes 'agent-relay cloud login'. The missing-session branch already names the CLOUD_API_* alternative; this one did not, so a non-interactive caller was misdirected to a command it cannot run. refreshAgentRelayStoredAuth cannot tell whether auth came from the stored file or the environment, so name both recovery paths rather than distinguish the source. Addresses the cubic P3 on #426. Same defect class as the two P1s this PR already fixes: an error prescribing an action that cannot work in the caller's context.
