The previous LLM-generated knowledge files contained factual
hallucinations. The most visible was the claim that `FindFirst` /
`FindLast` "forces a full-table scan" on an unfiltered record - it does
not; those APIs return a single row via the current key.
Other inaccuracies the audit found and fixed:
* `FindSet(true)` was described as "taking a LockTable". The correct
upstream phrasing is that `FindSet(true)` sets
`ReadIsolation::UpdLock` on the read. UpdLock and LockTable are
related but distinct mechanisms.
* The list of production-scale tables had been invented beyond the
upstream source (e.g. "Detailed Cust. Ledg. Entry") without a
citation. The regenerated list matches the ten tables upstream lists
with their P95 row counts.
* `SetLoadFields` guidance had been augmented with an extra mechanism
claim ("the database resolves the filter using the index without
hydrating the value") not present in upstream.
Approach: full regeneration of `microsoft/knowledge/` from the six
upstream BCApps Code Review instruction files, with Microsoft Learn /
the AL language reference as a secondary source. Every claim in every
regenerated file is anchored to a verbatim upstream quote (or a Learn
URL); the audit trail lives in artifacts/trace-<domain>.json on the
session workspace.
The PR #11 transaction/error-handling cluster is preserved verbatim:
* performance/understand-implicit-transaction-boundary.md
* performance/codeunit-run-as-atomic-sub-operation.{md,good.al,bad.al}
* performance/codeunit-run-requires-prior-commit-inside-transaction.{md,good.al,bad.al}
* performance/use-tryfunction-for-error-catching-not-rollback.{md,good.al,bad.al}
* performance/avoid-commit-inside-loops.{md,good.al,bad.al}
* security/commitbehavior-attribute-scopes-explicit-commits.{md,good.al,bad.al}
* testing/transactionmodel-attribute-governs-test-transactions.{md,good.al,bad.al}
These articles already cite Microsoft Learn and were carefully
cross-referenced; the regeneration skips their topics rather than
duplicating them.

Every page field needs a Caption (CodeCop AA0225/AA0226)
Description
CodeCop AA0225 and AA0226 require every field control to expose a Caption property, separately from the field's source name. The caption is what the user sees as the column header or label; the source name is what the code uses to reference the field. Without an explicit Caption, AL falls back to the source field's caption — which may be wrong for the page's context — or to the field name itself in code casing, which surfaces internal naming to users and to translators.
Acceptable exceptions: a field whose caption is inherited via CaptionClass = '3,5,' + CurrencyCode (or another CaptionClass formula) does not need a literal Caption; the formula provides it. API pages and test pages may omit captions because their consumers are not human users. Boolean fields whose name already reads as a sentence — Enabled, Posted, Released — do not need a redundant Caption that repeats the name.
Best Practice
Caption = 'Customer No.'; paired with ToolTip = 'Specifies …';. Captions are short, noun-phrase, title-case for primary labels; sentence-case is allowed for descriptive labels that read as a sentence fragment.
See sample: caption-required-on-page-fields.good.al.
Anti Pattern
A field control with no Caption and no CaptionClass, or Caption = '';. The user sees the internal identifier as the column header and the translation pipeline has nothing to translate.
See sample: caption-required-on-page-fields.bad.al.
