📝 WalkthroughWalkthroughThe PR expands Brev readiness diagnostics with four connectivity probes, SSH alias inspection, bounded error sanitization, timeout classification, and refresh deadline handling. E2E tests simulate probe outcomes and validate diagnostics, redaction, command arguments, cleanup, and polling behavior. ChangesBrev readiness diagnostics
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to Timeout diagnostics can misreport SSH alias availability, while important host-probe and success-path behaviors are not reliably covered by tests; this could produce misleading failure guidance and allow regressions to pass unnoticed, so the PR needs follow-up or explicit owner acceptance before merge.

SSH timeout flow, including the code at the deadline initialization and the
diagnostics triggered after readiness failure. Ensure diagnostics cannot add an
independent full BREV_READINESS_DIAGNOSTIC_TIMEOUT_SECONDS after the readiness

reserve diagnostic time within it, while preserving the existing failure
handling.

The aggregate elapsed-time assertion must enforce the same shared deadline

Summary
Add bounded, secret-safe failure diagnostics to the trusted staging Brev Launchable readiness lane. A timeout now preserves the latest sanitized refresh and direct host SSH evidence, reports alias presence and a four-path connectivity matrix, and classifies the failure without changing successful readiness behavior.
Changes

Report observedconfigured/missingstates,unavailablefor an unsuccessful query, andnot checkedwhen the diagnostic budget is exhausted.not run, and reportincomplete diagnosticsinstead of inferring reachability from an unobserved probe.Type of Change
