Teaches one GRC engineering concept at a time with retrieval and explain-back. USE WHEN learner asks what a term means, misuses a concept, needs a prerequisite before practice, or asks for a plain-language explanation. NOT FOR grading the learner's own explanation; use feynman-explainer.
Translates adjacent-domain patterns into GRC learning frames. USE WHEN learner is stuck, a concept feels abstract, a metaphor would expose structure, or learner needs to transfer a pattern from engineering, product, design, or operations. NOT FOR direct concept teaching when plain explanation is enough; use concept-tutor.
Grades the learner's teach-back explanation and identifies gaps in clarity, assumptions, and transfer. USE WHEN learner says they understand, submits a summary, prepares to explain to a stakeholder, or asks whether their explanation works. NOT FOR first-pass concept teaching; use concept-tutor.
Builds learning-safe mini-labs around toy or sanitized artefacts. USE WHEN learner wants hands-on practice, a portfolio project, build-based understanding, or a small artefact to prove learning. NOT FOR live audit prep, production policies, vendor assessment, control operation, or real programme work.
Designs a custom learning path based on role, gaps, goals, and time available. USE WHEN learner is new, has a goal but needs sequencing, is changing roles, wants credibility-building reps, or asks where to start. NOT FOR curating sources only; use reading-guide.
Creates fictional GRC scenarios and grades learner reasoning, assumptions, and tradeoffs. USE WHEN learner wants judgment practice, interview-style rehearsal, applied case work, or a safe way to try decisions before explanation. NOT FOR analyzing a real vendor, audit, control, policy, or programme.
Runs a lightweight re-check of an existing learner profile and proposes a visible diff. USE WHEN goals changed, several sessions have passed, profile feels stale, or 8-12 weeks have elapsed. NOT FOR cold-start intake; use profile-wizard.
Runs the cold-start learner profile intake and produces learner-owned context. USE WHEN learner is new, wants to seed context, imports learning background, or the Companion lacks enough signal to calibrate teaching. NOT FOR periodic profile updates; use profile-refresher.
