Job Agent v0.6.16

[0.6.16] - 2026-09-24

• Supply public root certificates for cloud and update connections automatically, preserving system trust and explicit custom CA settings.
• Check unauthenticated HTTPS after installation and expose a read-only jobagent doctor tls handoff with specific, redacted certificate diagnostics and bounded dependency repair.
• Preserve current tasks and account state; invalid certificates stay blocked without disabling verification or replaying requests.
