Narrow the relevant files to the subset that applies to the changes under review. For each relevant file, compute overlap against:
- The changed AL object names and types — especially tables, pages with SourceTable bindings, reports, queries, and codeunits performing record iteration.
- The changed procedures and triggers, weighted toward those that perform loops, Find/FindSet/FindFirst calls, CalcFields, CalcSums, FlowField access, or cross-table navigation.
- Tokens extracted from the diff that relate to data access and hot-path costs (`SetRange`, `SetFilter`, `SetLoadFields`, `SetCurrentKey`, `FindSet`, `ReadIsolation`, `LockTable`, `ModifyAll`, `DeleteAll`, `TextBuilder`, `Dictionary`, `temporary`, `repeat`, `until`, `CalcFields`, `CalcSums`).

- Tokens extracted from the diff that relate to data access and hot-path costs (`SetRange`, `SetFilter`, `SetLoadFields`, `SetCurrentKey`, `FindSet`, `ReadIsolation`, `LockTable`, `ModifyAll`, `DeleteAll`, `Modify`, `Delete`, `Copy`, `RecordRef`, `GetTable`, `TextBuilder`, `Dictionary`, `temporary`, `repeat`, `until`, `CalcFields`, `SetAutoCalcFields`, `CalcSums`).
A file enters the candidate worklist when its `keywords` intersect the extracted tokens or its topic (derived from the index entry's `path`, `title`, and `description`) matches a changed object type. Read an article's full file — its `## Best Practice` / `## Anti Pattern` bodies — only after it makes the worklist; candidate selection uses the index alone.
Apply these targeted cues even when simple token overlap would rank the article below the worklist cutoff:
- Worklist `use-setautocalcfields-for-per-row-flowfields.md` when a record loop calls `CalcFields`, or when every row reads the same FlowField for a comparison, branch, or per-record action. Worklist `calcsums-instead-of-calcfields-in-loop.md` instead when the loop only accumulates one set total.
- Worklist `avoid-cloning-records-before-modify-delete-in-loops.md` when an iteration calls `Copy` or `RecordRef.GetTable` before `Modify`/`Delete`, or passes the iterated record without `var` to a helper that writes that record. Do not match a read-only copy, a temporary record, a different target table, or a `RecordRef` opened and iterated directly.
Once the candidate worklist is known, resolve layer-precedence conflicts per READ. Drop lower-precedence files whose normative guidance (`## Best Practice` or `## Anti Pattern`) directly contradicts a higher-precedence candidate, and record each dropped file in `suppressed` with `reason: "layer-precedence"`. Files that would have been candidates but are hidden because their layer is disabled in consumer configuration are recorded with `reason: "configuration"`. Files that never became candidates are NOT recorded in `suppressed`.
When the post-conflict worklist is empty because no applicable performance knowledge exists, or because configuration suppressed every candidate, emit `outcome: "no-knowledge"`. When the worklist is empty because no applicable performance knowledge matched the changes, emit `outcome: "completed"` with an empty `findings` array.
