Systematic, evidence-driven architectural survey of a codebase that produces a persistent, navigable conspectus surviving across sessions and agent boundaries. Use whenever the user wants to map an unfamiliar codebase, survey a subsystem, run onboarding, resume a survey, refresh or audit the conspectus, browse field notes, build a concern checklist, run adversarial review of findings, or check what's stale. Trigger phrases include "run onboarding", "survey B-01" (or any subsystem id), "resume survey", "what's left", "what have you noticed", "audit the conspectus", "refresh conspectus", "reinit survey", "map the architecture", "explore this codebase". Also trigger for adjacent asks ("what do we know about X subsystem", "is there a finding on this file") whenever a conspectus is already on disk for the project, even if the user does not say "amanuensis".
