Jesper Schulz-Wedde e570d6113f Extract 55 knowledge articles from BC review-agent prompt
Adds 55 articles (plus 76 code samples) spanning four new domains and
two existing domains, extracted from the internal Business Central
review-agent prompt. Content was filtered against BCQuality's
remedial-knowledge premise: each article encodes BC-specific behaviour,
a CodeCop rule, a platform API semantic, or an anti-false-positive
guideline that a capable LLM would otherwise get wrong.

New domains:
- privacy (11 articles): DataClassification inheritance semantics, the
  StrSubstNo-defeats-Error-telemetry-classification pitfall, Privacy
  Notice consent for outgoing requests, anti-false-positives for pages
  and in-memory data.
- upgrade (11 articles): upgrade-codeunit structure, upgrade-tag
  lifecycle and registration, protected DB reads, DataTransfer for
  large datasets, InitValue semantics, enum-ordinal preservation,
  obsolete-workflow, first-install detection.
- ui (9 articles): caption capitalization by phrase type, tooltip voice,
  teaching-tip vs tooltip, tour-tip conventions, character limits,
  banned terms, ampersand handling, title punctuation.
- style (11 articles): label-suffix convention, API page naming,
  temporary-variable prefix, label properties (Comment/Locked), named
  invocations, FieldCaption in user messages, OptionCaption pairing,
  Error-parameter passing, `this` keyword, required parentheses, file
  naming.

Gaps in existing domains:
- performance (11 articles): production-scale table catalog (no row
  counts, per internal-data concern), anti-false-positive for bounded
  tables, guard-before-Get ordering, redundant-Get-in-OnAfterGetRecord,
  LockTable in read-only helpers, combined ModifyAll passes, writes in
  OnAfterGetRecord, SetLoadFields heuristics, temporary-table
  regressions, FlowField source-table widening, MaintainSQLIndex
  disabling SIFT.
- security (2 articles): environment-specific hardcoded GUIDs,
  ValidateTableRelation=false on user input.

Intentionally excluded: specific production P95 row-count numbers
(aggregated internal telemetry); rewritten as categorical guidance on
which tables to treat as production-scale without publishing sizes.

All articles use `bc-version: [all]` (applies to every BC version, per
the new schema sentinel). Validator passes with 0 errors / 0 warnings.

API pages follow strict naming and property rules that differ from regular pages

Description

Pages declared PageType = API are exposed through the OData API surface. The platform enforces a set of conventions that regular pages do not share: APIPublisher, APIGroup, EntityName, and EntitySetName must be camelCase alphanumeric only — no spaces, hyphens, or underscores. APIVersion must match the pattern vX.Y (for example v2.0) or the literal beta. EntityName is the singular form (customer); EntitySetName is the plural (customers). DelayedInsert = true is effectively required for the OData insert workflow to behave correctly on composite keys. These rules are platform-enforced and tooling-enforced; violations produce runtime errors or consumer-visible inconsistencies rather than soft warnings.

Best Practice

For every API page: camelCase alphanumeric API properties; APIVersion as vX.Y or beta; singular EntityName and plural EntitySetName; DelayedInsert = true. Keep these properties together near the top of the page definition so reviewers can check the set at a glance.

See sample: follow-api-page-naming-rules.good.al.

Anti Pattern

APIPublisher = 'Contoso-App' (hyphen rejected), EntityName = 'customers' and EntitySetName = 'customer' (swapped), APIVersion = 'v2' (missing minor version), DelayedInsert omitted. Each violation surfaces only when a consumer exercises the endpoint.
