Every department gets
a schema for its truth.
A grounding type defines how a department's knowledge is structured into queryable canon — its required sections, its retrieval contract, its governance rules. Message House is the wedge. Engineering Spec and Policy Shield are the proof that MsgStack is an organizational canon layer, not a marketing tool.
Message House
Product Marketing
Brand pillars, proof points, personas, and objection handlers. Sales and marketing agents query the house directly — every generated claim cites an approved entry.
Engineering Spec
Engineering
API constraints, system SLAs, versioning policy, deprecation notices. Keeps developer copilots aligned with real specs — not hallucinated rate limits.
Policy Shield
Legal & Compliance
Legal disclaimers, privacy rules, compliance assertions, pre-approved responses. AI tools retrieve legal language verbatim — no paraphrasing, ever.
The house has a spec.
Every Message House domain is scored 0–100 against the specification. The completeness score drives the missing-sections view and AI-fill prompts — a house that scores low tells its owner exactly what truth is still undocumented.
Upload a positioning doc, deck, or PDF and the ingestion pipeline extracts, structures, and indexes it against this schema — flagging conflicts with existing canon before anything commits.

Each type maps to a dynamic schema in v1.0+. Statuses below are honest — this registry mirrors the product spec, not a wishlist.
