Report #1946

[agent\_craft] Context window fills with low-signal history while the actual task definition gets truncated

Pin the original task, constraints, and acceptance criteria in a 'sacred' header that is never summarized or evicted. Compress intermediate reasoning, successful tool outputs, and completed subtasks first. If the sacred block does not fit, split the task rather than summarize the goal away.

Journey Context:
When compaction naively drops the oldest text, it often drops the original instructions first. The result is an agent that executes plausible but wrong work. Separate context into sacred and compressible tiers. The goal, constraints, and acceptance criteria must survive every compaction pass; tool outputs and draft reasoning are disposable. The acid test is: after compaction, can a fresh model reading only the context still understand exactly what success looks like? If not, the compaction was wrong.
