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.

Call objects by name, not by numeric ID
Description
Page.RunModal, Report.Run, Codeunit.Run, and the Page::, Report::, Codeunit::, Table::, XmlPort:: selectors accept either a numeric ID or a named alias. The named form — Page::"Posted Sales Shipment Lines", Report::"Sales - Invoice" — is the one to use. Numeric IDs are an implementation detail that change with renumbering, do not survive a rename, and carry no signal to a reader about what the call actually does. The compiler resolves named aliases at build time, so the named form is no slower than the numeric form.
Best Practice
When invoking an object whose named alias is available in the same app (or in a dependency the current app already references), use the named form: Page.RunModal(Page::"Posted Sales Shipment Lines", SalesShptLine), Report.Run(Report::"Sales - Invoice", true). The same applies to Codeunit.Run, XmlPort.Run, Query.Open, and any platform method that takes an object reference. The named form makes diffs reviewable — a rename is visible — and makes log output and stack traces interpretable.
See sample: named-invocations-not-object-ids.good.al.
Anti Pattern
Page.RunModal(525, …) or Report.Run(206, true). The numeric form is unreadable, fragile across renumbering, and breaks every search that looks for callers of a named object.
