* knowledge(style): allow event subscribers to omit trailing publisher parameters
The article told reviewers to copy the publisher signature exactly and reproduce every parameter verbatim. That contradicts events/add-new-event-parameters-at-the-end, which already states that existing subscribers bind to the leading parameters, and it produced a false positive on BCApps PR 10277 where a subscriber legitimately declared only the leading two of the publisher's three parameters.
Clarify that the name-match rule applies to every parameter the subscriber declares, state that AL binds on a leading prefix so trailing parameters may be omitted, and keep the real defect - a subscriber list that is not a prefix of the publisher's - as the anti pattern. Add the false-positive keyword for retrieval.
* fix: subscribers bind by parameter name, not by leading prefix
The first revision claimed AL binds a subscriber to a leading prefix of the publisher parameter list and that a parameter may not be skipped in the middle. That is wrong. Verified against shipping BCApps code: Test Runner - Mgt publishes OnBeforeTestMethodRun(var CurrentTestMethodLine; CodeunitID; CodeunitName; FunctionName; FunctionTestPermissions; var Skip), and ALTestRunnerResetEnvironment binds to it declaring (CodeunitID; CodeunitName; FunctionName; FunctionTestPermissions; var CurrentTestMethodLine) - omitting Skip and moving the first parameter to last. Binding is by name, so any subset in any order is valid. Detection now targets a parameter whose name or type matches nothing on the publisher.

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.
File counts after regeneration:
performance 35 .md (5 preserved + 30 new)
privacy 17 .md
security 18 .md (1 preserved + 17 new)
style 33 .md
