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.

Do not remove SourceTableTemporary or TableType = Temporary without understanding the impact
Description
SourceTableTemporary = true on a page, and TableType = Temporary on a table, mean the underlying record operates in memory — Insert/Modify/Delete mutate the session buffer, not the database. Removing either property converts the same operations to real SQL writes. On an API page that external callers hit at high frequency, on a background task that processes thousands of records, or on a UI page that composes an in-memory list for display, the change from temporary to persistent can turn a lightweight operation into a major source of database load. The refactor is easy to propose ("why is this temporary?") and expensive to regret.
Best Practice
When a diff removes SourceTableTemporary = true or TableType = Temporary, require justification explaining why persistence is now required and what paths still write. Review the callers for unexpected new writes, transaction scope, trigger fires, and contention. Keep the property unless the change genuinely needs persistence; an unused-looking temporary table on a bounded page is usually there for a reason.
Anti Pattern
A cleanup PR that deletes SourceTableTemporary = true from an API page "because the source table already exists". The API now writes to the real table on every call, every consumer's requests reach the database, and the incidental side-effects in the source table's triggers start firing across tenants.
