Three lines. One boundary.
DETAIL · THREE LINES · REDACTION ENGINE · INTEGRATION

General notes
- 01Redaction at the prompt boundary fits in three lines: redact on the way out, call the model, restore on the way back.
- 02The model reads a sentence that still makes sense. The real details never left. The reply comes back with the originals in place.
- 03Everything else in the engine exists to make those three lines safe under streaming, across chunk boundaries.

Three lines. One boundary.
Redact on the way out. Call the model. Restore on the way back.
The model reads a sentence that still makes sense. The real details never left. The originals return in the reply.
The rest exists to make those lines safe under streaming. Sheet 041.
