# Context engineering

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Long session has accumulated stale or conflicting context, or the user asks to refresh or recheck context before continuing. |
| Authority | Reversible local: writes only an optional scratch state note; rollback is undo. No remote mutation. |
| Side effect | Optional scratch state note only; no project files touched. |
| Done | Acting context is provably current and minimal; stale items are dropped with the user informed. |

## Inputs

- The current acting context present in the session: stated facts, assumptions, inferred file state, and prior decisions.
