Scope, effects & release evidence

Source status: Source and release references. Read the linked release record for publication evidence.
What changes: Discovery and skill inspection read evidence; browser actions and data collection can make changes. Each tool keeps its own contract.
Recovery: Inspect a tool before installation; use its own stop and recovery instructions.

Opening a guide does not install a tool or connect an account. Compare runtime requirements and exact release records.
