Project Start Prompt
Received notification from "Mid-Layer 4 Router Fix" that it finished — picking the work back up.
Thought for 9 sec

The workaround executor has settled. I’m reconciling its exact retained/reverted result against a fresh live DRC and targeted-routing canary now; I’ll continue only from the verified state.

I exhausted the safe project-side workarounds. This is conclusively a Flux targeted-router backend defect, not a malformed project layer reference:
- Active stackup canonically defines
Mid-Layer 4. - Existing copper correctly serializes as
routeSegment.layer="Mid-Layer 4". - The targeted router rejects that valid value before pathfinding.
- Normalizing the stackup broke via connectivity.
- Migrating copper to Mid-Layer 2 created shorts, airwires, and floating copper.
- All experiments were atomically reverted: checkpoint
#81f819bf, revert#ba5278cf. - Fresh state: 63 airwires, 2 protected USB-C warnings, 0 other DRC findings.
I filed an updated engineering escalation containing the serialized field, node counts, commits, reproduction steps, and failed workarounds.
Practical paths forward
- Use explicit copper primitives for each remaining connection; this bypasses the targeted router but is effectively manual routing.
- Export the design to KiCad or another EDA tool and complete placement/routing there.
- Wait for Flux to correct the backend layer importer, then resume targeted routing here.
Given the repeated failures and the unresolved VCAP/SDRAM placement redesign, exporting to KiCad is currently the lowest-risk path to completing this board. Flux support can be reached at https://docs.flux.ai/Introduction/getting-support.
