Most of the corpus — FindSet/SetLoadFields/CalcFields patterns, permission sets, SingleInstance codeunits, DataClassification, IsolatedStorage, transaction scope, SecretText — describes BC platform behaviour that is identical across supported versions. The seed [26..28] range on every file implied a version-specificity the content does not actually have, and there was no way to express "applies to every version" in the schema the way [w1] and [all] already do for countries and application-area. Extend the v1 schema with a universal sentinel for bc-version, parallel to the sentinels already defined for the other dimensions: bc-version: [all] # applies to every BC version [all] is mutually exclusive with explicit versions. Range shorthand ([26..28]) and explicit lists ([26, 27, 28]) continue to work for files genuinely tied to a version-gated API or deprecation. Update read.md (field definition, matching semantics, partial-context rule), write.md (default to [all], use ranges only with a concrete reason), README.md (frontmatter example), and the CI validator. All forty existing knowledge files and the three action skills convert to [all]; none of the current content is version-gated. Validator passes.

Add SIFT keys for FlowField aggregations
Description
CodeCop rule AA0232 checks that FlowFields backed by CalcSums or aggregation CalcFormula are supported by a key whose SumIndexFields include the summed field and whose key prefix matches the formula's filter fields. Without a SIFT key the platform falls back to a full aggregation on every read — typically invisible in development and catastrophic in production.
Best Practice
For each Sum-style FlowField, ensure the source table has a key whose leading fields match the FlowField's CalcFormula WHERE clause and whose SumIndexFields list includes the summed field. Table extensions adding new FlowFields are responsible for adding the supporting key.
See sample: add-sift-keys-for-flowfields.good.al.
Anti Pattern
Declaring a FlowField on a hot table without checking whether a supporting SIFT key exists ships a latent scan into every list page and report that touches the field.
