Jesper Schulz-Wedde 9a4198eb28 Add [all] sentinel to bc-version; apply to version-agnostic knowledge
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.

Choose Insert, Modify, and Delete parameters deliberately

Seed article. Converted from an existing performance-review prompt to bootstrap the BCQuality performance corpus. Domain stewards should expand, restructure, and refine as needed.

Description

Insert, Modify, and Delete accept a boolean that controls whether the table's OnInsert / OnModify / OnDelete trigger fires. Running the trigger for scratch or migrated data is often unnecessary work — side effects, posting rules, validations — for rows that were already validated upstream. Running the trigger when application logic depends on it is non-negotiable.

Best Practice

Call Insert(true), Modify(true), or Delete(true) when the table's trigger logic is part of the operation's semantics. Call Insert(false), Modify(false), or Delete(false) when the operation is bulk data movement or temporary-table manipulation and the trigger would duplicate work or fire invalid side effects.

See sample: use-insert-false-when-skipping-triggers.good.al.

Anti Pattern

Blindly passing true everywhere pays for triggers on rows that do not need them. Blindly passing false silently skips validations that the table's author intended to be mandatory.
