Firmware Debug from Evidence Agent

Embedded bugs are hard because the only evidence may be a watchdog reset, a stuck output or a wrong reading. This agent gathers the evidence, such as fault registers, logs, memory dumps and recent code changes, and forms a ranked list of likely causes, like a stack overflow, a race condition or a misconfigured peripheral. It proposes a safe way to test the top cause, such as adding a log point or reading a register, and interprets the result. If the result rules the cause out, it moves to the next one. Once a cause is confirmed, it proposes a fix and a test that reproduces the original conditions. You approve flashing any change to a device. Edge case: a crash that happens only when the device is cold is traced to startup timing, not treated as random.
