I’ve set the routing constraints you asked for.
Applied:
  • Q1, D1, T1: traceWidth = 1.0mm and minTraceWidth = 1.0mm
  • J1, J2, C3: minKeepOut = 6.0mm
What this means:
  • Your primary switching loop now carries a hard 1.0 mm routing constraint on the critical cluster, so when you route those airwires manually, Flux will enforce the wider copper on that section.
  • The secondary/output section now has a 6.0 mm isolation buffer around J1/J2/C3 to help maintain physical separation from the primary side.
One limitation:
  • I did not physically draw the copper traces. I was able to apply the DRC/layout constraints, but the primary loop still needs to be routed on the PCB canvas.
Current status:
  • Airwires are still present, so the board is not routed yet. That matches the expected workflow after constraint setup. The recommended verification pattern is to apply exact-width rules first, then route, then re-check airwires/DRC.
Recommended manual routing order:
  1. Route +12V → T1 primary → Q1/D1 loop first, keeping it as short and compact as possible.
  2. Keep that loop entirely on Top Layer if possible.
  3. Do not route primary copper into the 6 mm keepout region around J1/J2/C3.
  4. After that, route the low-power NE555 section.
  5. Re-run DRC and check for remaining airwires.
Also, the rule syntax requires exact metric values like 1.0mm and 6.0mm, which is why I used those explicit numbers.
If you want, I can next help you define:
  • a clearance rule for the primary loop, or
  • a step-by-step manual routing plan for the critical traces.
