The requirement to declare DataClassification explicitly in a tableextension
applies to the Normal fields it adds; FlowFields and FlowFilters are
SystemMetadata automatically and are covered by their own article. Being
added by a table extension is also not itself a finding - the finding is a
Normal field added by a table extension that has no valid explicit
DataClassification.

Table-level DataClassification is the effective default only for Normal
fields declared inside that table object. A tableextension cannot set the
property (AL0246) and its added fields do not inherit the base table value,
so AS0016 still requires each of them to classify itself. State this in both
privacy articles so the guidance cannot suppress genuine findings on the
tableextension pattern, which is how most partner code adds fields.
Also narrow the inheritance claim to verified AppSourceCop behaviour rather
than asserting platform-level resolution, and make the sample's table-level
default semantically representative of its fields while keeping a legitimate
field-level override and demonstrating the tableextension boundary.
Verified with alc.exe 18.0.37.11445 + Microsoft.Dynamics.Nav.AppSourceCop.dll:
the revised sample produces no AS0016, and removing the explicit
classification from the tableextension field makes AS0016 fire.

Document that valid table-level classifications are inherited by fields and update the privacy fixture and related guidance accordingly.

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:
