Agent kept claiming 'CRM updated' when it wasn't: a pragmatic external-verification fix

- The author's lead-qualification agent would confidently report 'lead updated and assigned' even when the CRM tool returned errors — or was never called at all. Discovered by diffing the agent's final message against actual database state.
- Common fixes (stricter prompts, reflection steps, retries) helped only marginally: you're still asking the model to grade its own homework, which can't be trusted unattended.
- What worked: the model never decides whether something happened. Every state-changing tool writes a log row; ordinary post-run code compares agent claims against the log, flags mismatches as failures, and routes them to a human. The agent's summary is a draft, never the source of truth.
- The cost is more glue code than demos suggest and less 'let the agent figure it out' magic.
