Zeta3 input is missing current-file editable context at curs

Error message

Zeta3 input is missing current-file editable context at cursor

What it means

The Zeta3 prompt input did not include an editable excerpt of the current file at the cursor, which the v0318 seed multi-region output parser requires to locate and apply marker spans. The input assembly step omitted or failed to produce current-file context.

Solutions

1. Ensure the prompt input is built with the current file's editable region around the cursor before parsing output
2. Skip the edit gracefully and log that input context was missing rather than treating it as a model failure
