The first audit pass: everything from 0.8.1 to 0.9.8 read as a whole rather than one feature at a time, starting with what a model is actually told. Four of these had shipped as correct. The date line carried a timezone variable that resolves to nothing until somebody chooses one -- so every default account was told times were "in unless they say otherwise", while two comments asserted the line disappeared instead. The prompt preview built its variables without a chat, which is what eleven fragments are gated on, so the whole agent surface was absent from it whatever was ticked. Plan mode was instructed to keep its plan current with a tool that mode withdraws. And knowledge_get returned a document whole where every sibling reader caps and says so, its description promising exactly that. The subagent guidance was wrong in both directions at once: it denied a documented parameter and named seven of twenty-three allowed commands. Both halves are pinned by tests against the real list and the real schema now, because prose and a constant drift the moment one is edited alone. docs/notes/audit-0.9.md carries the findings that are not fixed here, with why -- the ones whose fix would change what a feature does are the user's call, not this pass's.

"""Delegating a piece of a reply to a second, unattended model.

|
|
|
The whole risk of this feature is that the helper runs with nobody watching, so
|
|
almost every test here is about what it is *not* given. Restriction happens at
|
|
tool resolution, never in the prompt — so what these assert is the resolved set
|
|
and the row it comes from, not the wording that describes it.
|
|
|
|
The generation loop itself is stubbed. What it does with a chat is covered by
|
|
`test_generation.py`; what matters here is which chat it is handed.
