Twenty Crm Foundation

Use when building a multi-tenant application or CRM with dynamic schema — upgrade-aware repository proxies and cursor-driven metadata adapters, RLS predicate rewriting, normalized Postgres error taxonomies with duplicate-key diagnostics, workspace DDL managers, SQL identifier escaping, generation-stamped promise memoizers, integer-gap record ordering, metadata-driven upsert engine, tool-facing CRUD validation envelopes, ORM update-event fidelity contracts (id-keyed pairing, authoritative timestamps, snapshot clone discipline), timeline activity routing/coalescing kernel (hash-keyed routing plans, dual-emission junction repoints, sorted advisory-lock funnels), the GraphQL record-filter compiler (bracket-composition walker, where/andWhere first-entry semantics, permission-gated field parsing, depth-capped join-based MANY_TO_ONE sub-filters, composite sub-field flattening, ~18-operator parameterized SQL ladder with randomized param namespacing, null-equivalent widening vs strict eqStrict/isStrictly…

twenty-crm: Multi-Tenant CRM & Dynamic Schema Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: twenty-crm; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@9e4717278c29efa3ba0c147f6acf0d68e99a625c.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Zero-Downtime Upgrade Plane; Multi-Tenant ORM & Security; Error Handling & Diagnostics; Dynamic Schema & DDL Engine; Caching & Hydration; Record Ordering & Position; Upsert Engine; Tool-Facing CRUD Surface.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
