including diagnostics, telemetry, search indexing, design sync, link preview,
translation memory, calculators, chart rendering, CSV normalization, text
summarization, email draft autosave, and tax estimation.
- Salvage-derived, redacted regression cases from security penetration-test
artifacts, covering historical financial exfiltration paths through MCP tools
such as stock helpers, loan calculators, home search, presentation/graphics
assistants, legal advice, and underwriting/audit logging.
- An unauthorized destructive calendar mutation.
