Context Capsules

A Capsule is one compiled artifact: the passages that answer the goal, under a single token budget, each with its line span and content hash, plus a written statement of what could not be found. Your agent reads it once. You can verify it months later.

Explicit evidence gaps instead of invented synthesis
Deterministic JSON plus readable Markdown projections
Non-mutating verification for unchanged, stale, missing, and reranked evidence
