+- Required output: one concise Markdown dossier per client with exact name, one-sentence purpose, systems/clouds, plain-language system meaning, precise client relationship, identified contractor/company and role, direct evidence, confidence, and short gaps.
+- Investigation skill: `client-investigator`; recurring runs must deepen contractor research and patch the skill only with validated reusable practices.
 
 ## Automation
 
 - Cron job `88833e00b4a2` (`VSSA client cloud/system investigation`) runs at `0 */2 * * *` and reports to this channel.
 - Each run audits all 290 records, deeply researches up to 10 missing/weak/stale dossiers, updates the index, commits and pushes evidence-backed changes, and verifies remote state.
 - Research must prefer primary sources and must not infer providers/systems without corroborating evidence.
