Use this **instead of `git diff <ref>..<ref>`** when reviewing a PR,
auditing a refactor, or assessing merge safety — it answers "what
changed and what might break" in one tool invocation, with structured
JSON and per-function blast radius scores instead of raw diff text.
Replaces the common two-step workflow:
1. `get_change_manifest` — what changed
2. `get_function_context` — blast radius and callers
with a single call that runs both internally and splits the token
budget 40/60 (manifest / function_context). Two independent cursors
(`manifest_cursor`, `function_context_cursor`) let you page each half
separately without resetting the other.
