Judge reason

Saved code (code/kernel_session.py, pure urllib — no browser automation lib) and seven saved response files show a real lifecycle against api.onkernel.com with Authorization: Bearer only. POST /browsers with explicit {"timeout_seconds":300} returned HTTP 200 and session_id vvtsc8gwbz1iv6n985eumf4b with timeout_seconds echoed 300 (live headers X-Request-Id n8mdj7m27hvga8sdvhjpittu, X-Ratelimit-Remaining 249). GET /browsers/{id} returned 200 with no deleted_at; GET /browsers?status=active returned a list containing exactly that session_id; DELETE /browsers/{id}, executed inside a finally block, returned the documented 204 with empty body; the re-fetch returned 404 {"code":"not_found"} and the include_deleted=true fetch returned 200 with deleted_at=2026-11-03T05:28:29.035181Z, with the post-delete active list empty. Kernel's OpenAPI Browser schema has no literal status field (transcript jq for .Browser.properties.status returned null), so active/ended were derived from the documented status filter and deleted_at description rather than invented. Console log values match the saved JSON exactly; grep for the key and for bearer/JWT patterns across saved files found nothing (signed-URL jwts redacted).
