 Reviews AL source changes against the `data-modeling` knowledge domain in BCQuality and emits a findings report. This is a leaf action skill: it invokes no sub-skills. It is one of the skills composed by `al-code-review`.
 
-An orchestrator invokes this skill with a `pr-diff`, `file-path`, or `folder-path`. Data-modeling findings are narrow by design — they apply when the review scope contains setup or master tables, their card pages, primary keys, number-series assignment, block enforcement, audit fields, document print/email/Post-and-Send actions, `Navigate` page subscribers, Report Selection registration or dispatch, price-calculation/price-source extensibility, `TransferFields`-based posting-cascade field mirroring, barcode/report-layout font-provider usage, dimension wiring, journal-based posting-routine structure, or Item Ledger Entry document-number lookups after a combined sales post. The skill returns `not-applicable` when none of those apply.

 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. When the diff contains no data-modeling changes by any of the above signals, return `outcome: "not-applicable"` without evaluating files.
 
@@ -66,6 +66,7 @@ The following targeted checks cover every current `data-modeling` article. Treat
 - An `enumextension` extends `"Price Calculation Handler"` and implements the `Price Calculation` interface, without a matching `OnFindSupportedSetup` subscriber inserting a `Price Calculation Setup` record naming that implementation as the `Implementation` for a `Method`/`Type`/`Asset Type` — `activate-new-price-calculation-handler-via-onfindsupportedsetup`. `Default := true` is only required on that row when it is meant as the fallback for its `Method`/`Type`/`Asset Type` combination; a row meant to be selected only through an explicit, specific `"Dtld. Price Calculation Setup"` row does not need it, so do not flag a missing `Default := true` by itself — flag the missing setup row/subscriber entirely.
 - An `enumextension` extends `"Price Source Type"` with a new value intended for a sales, purchase, or job price list, without extending the matching document subset enum (`"Sales Price Source Type"`, `"Purchase Price Source Type"`, `"Job Price Source Type"`) with a value at the same numeric ID — `extend-price-source-type-must-sync-document-subset-enum`.
 - A codeunit subscribes to `"Sales Line - Price"`'s `OnAfterAddSources` to register a custom field as a price source via `PriceSourceList.Add`, but that field has no `OnValidate` (or matching `OnAfterValidate`) that triggers recalculation — either `SalesLine.UpdateUnitPrice(<field no.>)`, or the explicit `SalesLine.PlanPriceCalcByField(<field no.>)` followed by `SalesLine.UpdateUnitPriceByField(<same field no.>)`. A bare `UpdateUnitPriceByField` without a preceding `PlanPriceCalcByField` for the same field number does not count as recalculation (it exits without recalculating) — `new-price-source-must-add-candidate-and-trigger-recalculation`.
+- Code reads `Unit Price`, `Direct Unit Cost`, `Line Amount`, `Line Discount Amount`, `Inv. Discount Amount`, or `Prepmt. Line Amount` of a `Sales Line`/`Purchase Line` as a known net or gross value (a net/gross total, a VAT computation, a comparison with `Item."Unit Price"`/`"Last Direct Cost"`, an export), or writes a source price of known basis into `Unit Price`/`Direct Unit Cost`, without reading the document header's `Prices Including VAT` — `document-line-prices-follow-prices-including-vat`. Reads of `Amount`/`Amount Including VAT`, prices returned by the standard price calculation, and copies between lines of the same document are not this anti-pattern.
 - A report hand-constructs a barcode string only where a concrete, independently provable defect is visible: the source value can contain characters outside the symbology's character set and is never validated, a checksum the symbology/setup requires is never applied, or there is concrete evidence of an incompatible font binding. Do not flag manual start/stop delimiters by themselves — `*value*` is a documented, valid Code 39 form for IDAutomation fonts (IDAutomation also accepts parentheses), so delimiter choice alone is never a finding. Also flag module use that does not match the interface: a 1D `"Barcode Font Provider"` path must call both `ValidateInput` and `EncodeFont`; a 2D `"Barcode Font Provider 2D"` path calls `EncodeFont` only (the 2D interface has no `ValidateInput`, so its absence there is not a finding). Separately, flag an otherwise correctly encoded barcode whose report layout names an evaluation/demo font instead of the purchased production font name — `report-barcodes-must-use-barcode-module-and-production-font-name`.
 - A new field is typed `Code`/`Text` and its `OnValidate` calls `DimensionManagement`/`DimMgt`, or a table adds Shortcut Dimension fields, a `Dimension Set ID` field, or `AddDimSource`/`GetDefaultDimID` — `dimension-management-wiring`. A master table calling `SaveDefaultDim` and a document/journal table computing its own `Dimension Set ID` are two different valid shapes; do not flag a master table for lacking a `Dimension Set ID` field or a document for lacking `SaveDefaultDim`.
 - A journal-based posting codeunit is added or changed and validation, Journal-table access, ledger writes, and user-interaction (`Confirm`/dialogs) all occur in one procedure or one codeunit, rather than split across `Check Line`/`Post Line`/`Post Batch`-shaped companions — `check-post-line-batch-pattern`. A document posting routine calling `Post Line` directly without a `Post Batch` companion is not this anti-pattern.
