# CRISPcore

> CRISP conforms many operational sources to one programme model - Conform / Rules / Identity / Span / Publish - with sparse Identity clusters and a governed Publish contract.

This file is the agent entry index for https://crispcore.org. Prefer these files over scraping the marketing homepage.

## Start here

- [Implementer pack (full)](https://crispcore.org/llms-full.txt): Fail-closed checklist, named stage ownership, necessary Rules families (boolean/enum eligibility; silver-first grain/integrity), coalesce, Identity rebuild, extensions, Publish measures - read this before designing schemas.
- [Implementer checklist (HTML)](https://crispcore.org/for-agents/): Same gates in a readable page.
- [Pipeline](https://crispcore.org/pipeline/): Four CORE stages with named ownership (not medallion tiers). Conform is the first enterprise write; the Rules catalogue may also be used on source tables first.

## Non-negotiables (fail-closed)

A design is **not CRISP-shaped** unless all of these hold:

1. C->R->I->S->P named ownership. Conform is the first enterprise write; the Rules catalogue may also run against source tables first. Identity waits until enabled Rules have completed on written facts. CRISP sits after silver; it is not a rename of bronze/silver/gold. Publish is a better gold.
2. Conform = `{SUBJECT}_HEADER` + versioned assertions - no dense masters; no Conform `FACT_*`/`DIM_*`.
3. ROLE/LINK for relationships; Identity clusters **headers**; money/roles do **not** cluster.
4. Tritemporal axes; trusted load stamps `warehouse_*`; do not put warehouse_* on Span/Publish columns.
5. Rules = Catalogue + Map (`row_kind`) keyed by `source_system`, plus specialised families only when the join is not a simple code swap (sign, lifecycle, measure eligibility, expansion, integrity) - not one global map, not a family per KPI.
6. `consume_key = COALESCE(cluster, header)`; Span AS_IS / AS_WAS / AS_WAS_AT (AS_WAS uses **current** clusters).
7. Publish = consumer semantic contract + named KPIs; optional thin format projector **after** Publish.
8. Adaptors per source; lane variance in `extensions`; land/clean upstream of Conform. Prefer to split one source row into several, and to check across rows, in silver (source keys still visible). When silver cannot, those instructions live in CONFORM_RULE; the adaptor may apply them against queryable source tables before writing Conform.

## Out of scope on this site

Industry models (ACORD, FHIR, ...), cloud glue tooling, and org politics are **programme** concerns. CRISP owns *how* sources become Publish; industry packs are optional lenses - not a wholesale copy into CORE.
