| Knowledge base | It states what your material never said | Knowledge base | Whether the turn queried the knowledge base, and what it got | Fix the document and re-chunk it. One fix covers the whole team that uses it. |
|---|
| Stage and script | Facts right, but it went too far — over-promised, or skipped a required step | Stage and script | Which stage it reached, and that stage’s goal and instructions | Rewrite that stage’s instructions, and the condition for moving on. |
|---|
| Tools | A required tool never ran — no stock check, no slot held, no ticket | Tools | Which tools the turn called, and with what arguments | Change the available tools, and make “must call” and “must not call” hard rules. |
|---|
| Config version | Fine yesterday, wrong today | Config version | The config version it ran on | Roll back. Every change is saved as a new version before it goes live. |
