Tirith redacts its own findings, but the approval-request callbacks built the
operator prompt from the RAW command string, so a credential-shaped value
Tirith flagged was sent verbatim to clients, undoing the redaction one layer up.
Two egress transports carried the leak; both are fixed via a shared
module-level seam _redact_approval_command() (redact_sensitive_text force=True):
1. chat platforms — _approval_notify_sync (gateway/run.py): redact before
both the button path (send_exec_approval) and the plain-text /approve
fallback.
2. SSE/API stream — _approval_notify (gateway/platforms/api_server.py):
redact event['command'] before it is enqueued to API/desktop clients.
(whole-bug-class: sibling call path on a separate transport.)
force=True so the prompt — a hard secret-egress boundary — honors redaction
even when security.redact_secrets is off. Clean commands pass through unchanged.
Tests bind the seam (synthetic credential-format fixtures, force-when-disabled) AND assert
BOTH callbacks ASSIGN the redacted result before the send/enqueue sink, via an
AST contract that rejects a discarded-result call. All mutation-checked.
