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.

begin goes on the same line as then, else, or do (CodeCop AA0005)
Description
When a compound block follows then, else, or do, the begin keyword must sit on the same line as the preceding keyword, separated by exactly one space. if Condition then begin and for i := 1 to N do begin are correct. The form that puts begin on its own line — common in older AL and in languages like Pascal — is flagged by CodeCop AA0005. The rule does not change indentation of the block body; it only governs the placement of begin relative to then/else/do.
Best Practice
if Condition then begin … end;, else begin … end;, for i := 1 to N do begin … end;. The block body is indented one level below the if/for line, and end; sits at the same indentation as the line that opened the block.
See sample: begin-on-same-line-as-then-else-do.good.al.
Anti Pattern
A line that ends with then (or else, or do) and is followed by a line whose only content is begin. The compiler accepts it but CodeCop AA0005 flags it; the visual cost is a wasted line per block and a layout that looks alien to readers used to current AL style.
