Produces an LPM working view on a single matter — a focused zoom-in for the LPM's own operational use, not for distribution. Structured around deliverables (what is due, when, to whom), issues (current problems requiring action), and risks (plausible future problems requiring monitoring). Use when the user asks "drill into [matter]", "brief me on [matter]", "focus on [matter]", "zoom into [matter]", "prep me for [partner] call on [matter]", "I'm handing [matter] to [name]", "leave cover on [matter]", "taking over [matter]", or pastes single-matter correspondence asking for a working view. Four modes: standard drill-down, decision-first, partner prep, handoff briefing. Not for status reports for distribution (use status-report-drafter) or portfolio views across multiple matters (use daily-briefing). Produces a .docx working view saved to the matter folder.
