# Resource optimization for low-end systems

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Firmware exceeds its flash or RAM budget, a stack overflows in production, a linker map needs reading, or `-Os` versus `-O2` needs deciding per file. |
| Authority | Read-only. Emits analysis and commands for the operator to run; no file writes, no rollback needed. No remote mutation. |
| Side effect | Measurement commands and a size verdict in chat. Nothing is written. |
| Done | The largest flash or RAM consumers are named from the map file, and each has a stated reduction tactic. |

## Inputs

1. Firmware ELF and map file (required): the linked image plus the `-Wl,-Map=` output.
