The same plain-backtick "See sample: \`x.good.al\`." form fixed on
al-methods-limited-during-write-transactions (PR #161) turned up
repo-wide on 15 more of this PR's articles - Knowledge-Retrieval.ps1
requires the markdown-link form to associate a sample with its
article. All 16 fixed; the four local validators (frontmatter,
knowledge-index, knowledge-retrieval, review-fixtures, skill-index)
pass.
- dimension-management-wiring: SaveDefaultDim's third argument is the
shortcut dimension number (1-8), not the field's AL field ID; the
fixture passed FieldNo(...) = 10. GetDefaultDimID's InheritFromDimSetID
must be 0 when recomputing after the linking record changes, not the
document's existing Dimension Set ID (which would retain the previous
customer's leftover dimensions). Verified against
DimensionManagement.Codeunit.al and BankDepositHeader.Table.al in the
BCApps reference clone.
- check-post-line-batch-pattern: "Post Line writes exactly one line to
the ledger" overclaimed - Gen. Jnl.-Post Line alone calls InsertGLEntry
from a dozen call sites (balancing entry, VAT, currency rounding,
deferrals) and can write several G/L Entries per journal line.
Reworded to "posts exactly one journal line" and softened the
"distinct, non-overlapping responsibilities" absolute.
- namespace-must-be-verified-from-source.bad.al: dropped the "resolves
in a local build, fails in VS Code" comment (taught an inherent
compiler/language-server disagreement that isn't real); reframed as
stale/cached symbols, matching the prose fix already made.
- file-datatype-saas.good.al: replaced the deprecated 5-argument
UploadIntoStream overload with the current 2-argument one, and
actually staged through TempBlob as the article's own Best Practice
instructs (the declared TempBlob variable was previously unused).
- test-data-must-be-random-and-complete: no longer treats a
short-but-valid value as defective merely for being "underfilled" -
AL field lengths are maxima, not minimums. Scoped to missing values
or a scenario with an explicit length/format requirement (e.g. a
truncation test). Updated the al-testing-review.md routing cue to
match.
- stored-derived-fields-must-not-be-exposed-directly: stopped mandating
source-field exposure as part of the core pattern: the good fixture
exposed only one of the derived value's two inputs (Hours Used, not
Budgeted Hours), making the claimed "so the consumer can verify it"
impossible. Reframed as an optional, all-or-nothing addition and
fixed the fixture to expose both inputs.
Rebased onto upstream/main to resolve conflicts in
al-breaking-changes-review.md, al-data-modeling-review.md,
al-performance-review.md, and al-style-review.md against merged PRs
#148 and #153; all sides' worklist tokens/cues retained.
- dimension-management-wiring.md/.good.al: split into the two distinct
models the article was conflating - master data (Default Dimension
records via ValidateDimValueCode/SaveDefaultDim) vs. transactional/
document data (a single Dimension Set ID assembled via AddDimSource +
GetDefaultDimID, verified against BCApps' ExchRateAdjmtProcess.Codeunit.al).
Added a compiling document-table example alongside the existing master
table one.
- Deleted api-page-flowfields-must-be-calcfields (.md/.good.al/.bad.al):
Microsoft's own FlowFields documentation states a FlowField used as a
control's direct source expression is automatically calculated on any
page - no API-page exception is documented, and none could be
reproduced.
- prefer-email-module.bad.al/.md: Codeunit Mail has no Send/GetErrorDesc
members; fixed to the real current 7-argument CreateMessage signature,
and corrected the claim that the legacy path "still runs" - its base
implementation no longer sends anything, only raises integration events.
- check-post-line-batch-pattern.md/.good.al: reframed from a universal
invariant to the standard shape, naming the real Gen./Item/CA/Res./Job/
Insurance/Mfg. Item/FA Jnl.-Check Line/-Post Line/-Post Batch codeunits
it's based on. Added the missing Check Line companion codeunit so the
good fixture is internally complete.
- test-data-must-be-random-and-complete.good.al: removed leftover
"collision-free" wording contradicting the already-corrected article text.
- fixed-choice-set-must-use-enum-not-integer.md: removed the reintroduced
state-count heuristic ("the line is the state count"), aligned with
binary-choice-must-be-boolean.md's semantics-based distinction.
- namespace-must-be-verified-from-source.md: removed the false claim that
the compiler and AL Language Server use different namespace-resolution
rules.
- intrinsic-al-functions-must-use-modern-casing.md: removed the unverified
claim that PascalCase is the VS Code formatter's default output.
Worklist completeness: added cues for the 8 rules in data-modeling,
testing, performance, and web-services that had none (Jesper's explicit
ask), plus the same gap in all 7 style rules from this PR (not explicitly
named this round, but the identical systemic issue) - 15 cues total across
al-data-modeling-review.md, al-testing-review.md, al-performance-review.md,
al-web-services-review.md, and al-style-review.md.

al.outputPath setting; reframe as build-artifact hygiene sourced
from ALTool --outfolder / al_build outputPath.

distinguish it from the underlying Sent/Outbox/Draft storage.
- file-datatype-saas.md: File.Open/Create/Read/Write fails to compile
against a Cloud-scoped project, it does not compile and silently
fail at runtime.
- namespace-must-be-verified-from-source.md: narrow to "resolve from
the referenced object's source or symbols," since source-file line
one is not the only authoritative source (symbol packages, comments
before the namespace line).
- test-data-must-be-random-and-complete.md: drop "assume an empty
database" and "collision-free" absolutes; reframe around
independence from unrelated business records and reserving explicit
values for scenario-defining inputs.
- binary-choice-must-be-boolean.md: scope to genuine true/false
semantics, not mechanical two-member-enum-to-boolean conversion.
- document-report-word-layout.md: scope down to a sourced Microsoft
Learn recommendation instead of an unconditional performance
guarantee; cite the three Learn pages.
- Wire the new articles into their review skills' candidate-selection
signals (file-datatype-saas, prefer-email-module,
namespace-must-be-verified-from-source, var-parameters-require-an-
addressable-variable) so they can actually enter a worklist.

* Add Finance posting domain-knowledge pilot
Adds three atomic domain-rule knowledge files under community/knowledge/finance/ as a pilot for Type-A (normative) Business Central domain knowledge: post through the posting engine, treat posted ledger entries as immutable, and treat the Dimension Set ID as the source of truth for dimensions. Includes a good/bad AL sample pair for the posting rule.
These encode BC-specific invariants that LLMs reliably get wrong, fitting the existing remedial/atomic knowledge grain with no schema or contract changes. Passes the repo frontmatter validator and is discovered by the knowledge index.

* Clarify editable operational fields on posted ledger entries
Addresses review feedback from @JeremyVyska on PR #57: the immutability rule applies to financial content, not the whole entry. Reframes the Description around financial content and gives the operational-field exception (payment/application data, on-hold, applies-to, communication fields edited via CustEntry-Edit/VendEntry-Edit and the ledger entry pages) its own paragraph in Best Practice instead of understating it as a narrow set.

New remedial article for spotting when AL calls an endpoint that does not

post-DisableHttpsCheck HTTP) and requires the response to be size-, schema-, and
request/response-integrity-validated before it is trusted. Includes the
BC-specific false-positive clarifications (platform buffers the full body, so an
in-AL size check after buffering is correct; no DNS-rebinding/bounded-read demand;
HTTPS not always enforceable) plus good/bad AL samples.

* knowledge(events): ChangeCompany leaves triggers and trigger-event subscribers running in the calling company
ChangeCompany redirects only the data access of a record variable; Learn states that triggers still run in the current company. The database trigger events are raised on every database operation and only pass RunTrigger to the subscriber, so Insert(false) after ChangeCompany still runs every subscriber in the calling company. Generated code either assumes the record 'becomes' a target-company record, or switches RunTrigger off and hand-copies the trigger logic, leaving the subscribers writing to the wrong company; none of the tested runs reached StartSession with the company parameter.

* knowledge(events): qualify StartSession async semantics and fix concurrency-unsafe sample key
Addresses PR #152 review: StartSession is a fire-and-forget background
session (Ok reports only whether it started, not whether the codeunit
succeeded, and errors inside it do not propagate), so the Best Practice
now scopes the recommendation and calls out the durable status/error
channel a synchronous-success write needs. The good sample's
FindLast()+1 entry-number pattern raced under concurrent background
sessions; switched to AutoIncrement, which the platform guarantees is
unique across concurrent transactions.

* knowledge(events): serialize the setup-counter increment; promote article and wire the review skill
PR #152 round 3 (JesperSchulz):
- The good sample's OnAfterInsertEvent subscriber still raced on the
shared "Transfer Setup Good" singleton (Get/increment/Modify);
AutoIncrement only protected the request key. Added
TransferSetup.LockTable() before Get() to serialize concurrent
background sessions.
- Promoted changecompany-runs-triggers-in-the-calling-company from
community/knowledge/events/ to microsoft/knowledge/events/, and wired
ChangeCompany/StartSession/RunTrigger tokens plus a targeted
detection cue into microsoft/skills/review/al-events-review.md so a
diff containing the anti-pattern reliably worklists this article,
preserving the documented RunTrigger=false hand-off exception.

* Fix bc-version overflow and pathless-row identity in bounded retrieval
Catalog matching compared an Int32 -BCVersion against a bigint range bound.
PowerShell coerces the right operand to the left operand's type, so a bound
wider than Int32 threw a conversion error and failed the whole domain catalog
rather than the single row. Metadata validation already accepts such bounds,
so compare as bigint on both sides.
The shared pager built its oversized-row message with $row.path, which
throws under Set-StrictMode -Version Latest when a row carries no path,
replacing the explicit bound failure with a property-lookup error. Resolve the
path defensively for dictionary and object rows so the offset-based fallback
is reachable.
Both paths gain regression coverage that fails without these fixes.

* Anchor plugin paths at PLUGIN_ROOT and restore the layer-filter caveat
The adapter delegated index preparation to Entry's Preparation step, but that
step is written for the clone model: it runs `pwsh ./tools/Build-KnowledgeIndex.ps1`
from the checkout root. A plugin host's working directory is the user's own
project, so the path does not resolve and the index is never built. Because
knowledge-index.json is gitignored, a fresh install has none, and READ silently
degrades to path-based discovery. The adapter now resolves Entry's repo-relative
paths against PLUGIN_ROOT and names the absolute index build; the generator
resolves its own root, so it indexes and writes the right tree from any cwd.
Entry also asserted that pruning has always happened before it runs, which is
false for an installation that ships the whole tree. Entry now scopes that
guarantee to consumers that actually prune, and the caveat dropped in the
rewrite - that enabled-layers narrows discovery rather than denying access - is
restored in the adapter and summarized in the README.

* Add community knowledge on AL boolean operators not short-circuiting
AL gives no short-circuit (lazy) evaluation guarantee for and/or/xor —
neither the AL operators nor the boolean operators documentation defines a
lazy evaluation order. LLMs trained on C#, JavaScript, or SQL assume the
left operand guards the right, which produces conditions where a guard
does not protect an unsafe subscript or a field read after a failed Get,
and where an expensive operand is paid on every path.
Adds community/knowledge/performance/boolean-operators-do-not-short-circuit.md
with good/bad AL companions. The guidance prefers nested if when one operand
depends on another, while keeping and/or legitimate for operands that are
independently safe and cheap, so a reviewer does not flag harmless bound
checks. This is the first article in a community performance domain; the
Microsoft performance review leaf skill already sources candidates by domain
across every enabled layer, so no skill change is needed to reach it.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* Add case true of pattern for long condition chains
Follow-up from PR review: nested if is the right answer for two or three
dependent conditions, but past that the nesting becomes the problem. AL's
case statement is the flat alternative — the control statements
documentation states a value set "must be an expression or a range" and
that the first matching value set executes, so case true of / case false of
accept boolean expressions and stop at the first match. That is the
laziness the boolean operators do not provide.
Adds case-true-of-for-long-condition-chains.md with good/bad AL companions:
case false of for guard chains where every condition must hold, case true of
for first-match dispatch. The bad sample shows both failure shapes — a
five-level if ladder, and the worse escape of collapsing it into an and
chain, which trades nesting for a real defect.
Cross-links both articles, and adds the threshold to the short-circuit
article's Best Practice so following it does not lead to a deep ladder.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* Comma-group the pure value sets in the case false of sample
Review feedback: the five value sets sharing exit(false) should be comma
separated. Applied to the three that are pure field reads with no order
dependency.
The Get and the Blocked read keep their own value sets. The documentation
guarantees that the first matching value set executes, which orders matching
across separate value sets; it says nothing about evaluation within one
comma-separated set, and the natural lowering of that is an equality-or
chain — where AL's or does not short-circuit. Grouping the Get with the
checks that must precede it would rest the sample's correctness on
undocumented behaviour, which is the defect these two articles exist to
prevent.
Encodes the boundary in the Best Practice section so the grouping is applied
where it is safe and not where it is not, and scopes the repeated-exit
detection signal explicitly to nested chains so the case sample does not read
as its own anti-pattern.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* Use a single exit(false) for the whole case false of chain
Review decision: all five conditions share one action, so they share one
comma-separated value set with a single exit(false).
Aligns the article's Best Practice with the sample — it previously told
authors to keep side-effecting conditions in their own value set, which the
sample no longer does — and drops the now-contradictory wording about listing
the failure action per condition.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* Drop the parentheses from the case false of value sets
Applies NKarolak's review suggestion: a case value set needs no parentheses
around a comparison.
Encodes the rationale in the Best Practice section, since it is a real
advantage of the pattern and is not documented elsewhere in the repo. The AL
operator hierarchy places and/xor above the comparison operators and or just
above them too, so parentheses are mandatory in an and chain — A = B and
C = D misparses without them — while a case value set has no and to bind
tighter and needs none. That inverts the precedence most developers arrive
with from C#.
Also notes in the bad sample that its parentheses are not optional, so the
two samples contrast on parentheses as well as on evaluation.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* Address correctness review: or/xor pattern, case value-set ordering
Fixes two points from JesperSchulz's review on PR #136.
1. boolean-operators-do-not-short-circuit.md gave one fix — nested if — for
and, or, and xor alike. That's only correct for and: nesting if A then if
B then Action drops the A-true/B-false case of A or B, silently changing
the result. Gives or its own early-exit pattern (if A then exit(true);
exit(B)), warns explicitly against applying the and-rewrite to or, and
clarifies that xor is not a short-circuit candidate in any language since
its result always depends on both operands. Adds an or fixture
(IsEligibleForFreeShipping) to both samples so an agent has a concrete
pattern to match instead of extrapolating from the and-only examples.
2. case-true-of-for-long-condition-chains.md derived stop-at-first-match for
one comma-separated value set from the documentation's guarantee about
the first matching value set — plural, i.e. ordering across value sets,
which is not the same claim. The good sample's Item.Get / Blocked pair
depended on the one the docs don't make. Restructures the sample to only
comma-group the three pure, order-independent checks; Get and Blocked
keep their own value sets, in order, relying solely on the guarantee that
is actually documented. Description and Anti Pattern now state that
boundary so it isn't re-collapsed later.
Also carries forward a parenthesis fix (not Item.Blocked in the collapsed
bad sample) that was made two commits ago but never landed.

* knowledge(performance): align SetLoadFields placement with AL Guidelines (#120)
The AL Guidelines mark `SetLoadFields` placed before `SetRange`/`SetFilter`
as bad code and recommend filters first, while the BCQuality samples used
the opposite order — contradictory guidance across two Microsoft repos.
Per Learn (`Record.SetLoadFields`), "fields that are filtered upon are
always loaded", so the two orders produce an identical projection. The
upstream rule is a readability convention: keep `SetLoadFields` adjacent
to the read it governs.
- Reorder filters ahead of `SetLoadFields` in the six affected AL samples.
- State the placement convention in the Best Practice section.
- Record in Description that order does not change the projection, and
that only a fieldless `SetLoadFields()` or a later overwriting call does.
- Add an Anti Pattern note so review agents treat the reverse order as a
readability observation, never a performance defect.

* Clarify partial-record projection changes
Document AddLoadFields, SetBaseLoadFields, and Reset alongside SetLoadFields so the statement-order guidance does not imply those APIs leave the projection unchanged.

The narrowed UI-handler guidance still stated the execution rule without the
qualifier the linked Microsoft reference uses. The article said every listed
handler must execute at least once, and the testing leaf skill asked for
`[HandlerFunctions(...)]` to match the invoked handlers exactly. The reference
says every *nonoptional* listed handler must execute, and that send-notification
and recall-notification handlers can be optional. As written, an agent could
flag a deliberately unused optional notification handler.
The discriminator is narrower than the handler type. Both
`[SendNotificationHandler([HandlerIsOptional: Boolean])]` and
`[RecallNotificationHandler([HandlerIsOptional: Boolean])]` take an explicit
optionality argument, so `[SendNotificationHandler(true)]` is exempt while the
same attribute written without the argument stays nonoptional like every other
handler type. Keying the exemption on the argument rather than the type keeps it
checkable from the diff and avoids the opposite false positive, where an agent
stops flagging genuinely nonoptional notification handlers.
Changes:
- The article now states the nonoptional qualifier, explains that optionality is
declared rather than inferred, and adds an explicit do-not-flag clause. That
clause also forbids proposing removal, because the listed entry is what keeps
the test passing on the runs where the notification does fire.
- The testing leaf skill carries the same boundary in its `ui-handlers-in-tests`
cue, and its mechanical-fix list no longer allows removing a listed optional
notification handler as a one-click suggestion.
- `SendNotificationHandler` and `RecallNotificationHandler` were missing from the
skill's testing token list, so notification handlers were not reliably
surfaced to the relevance step at all. Both are now listed.
- The good sample gains a test that lists an unreached
`[SendNotificationHandler(true)]`; the bad sample gains the mirror image, an
unreached `[SendNotificationHandler]` with no optionality argument. The pair
differs only by that argument, which is the point.
- `evaluation/review-fixtures.json` pins the testing domain to
`ui-handlers-in-tests` so the boundary is exercised: the good sample is the
clean control at `minimumCleanRate` 1.0 and the bad sample is the expected
finding. Keywords were retagged with `notification` and `optional-handler`.

data-modeling: add insert-only-transfer-may-rely-on-caller-cleanup. A filter-and-insert transfer routine was reported for stale rows and duplicate keys even though the field OnValidate trigger calls a sibling cleanup procedure that clears the same range immediately before it. Deciding this requires reading the caller, so the article asks reviewers to trace call sites and keeps uncleared or mismatched-filter paths reportable.
appsource: scope two-level-namespace-replaces-object-affix-not-extension-member-affix to apps that actually configure a mandatory affix. AS0011 only runs when AppSourceCop is enabled with a mandatory affix; a first-party in-box app that ships no such configuration is not subject to it. The member-affix requirement itself is unchanged for apps that do configure one.
testing: allow permission-tests-must-lower-the-execution-context to accept a composed role. The article demanded the exact permission set under test be assigned directly, so a test that lowered permissions through a role including that set and then asserted WritePermission was false was reported as a coverage gap. What matters is the effective context plus a boundary assertion, not which object the test names.

The article was rewritten to say a reset is required only when the value can
carry over, and its H1 was updated to match, but three artefacts still carried
the old "always initialize to false" premise:
- The slug still read `initialize-ishandled-to-false-before-publishing`, which
contradicts the body. The slug is not cosmetic: Build-KnowledgeIndex.ps1
ranks candidates on keywords, frontmatter dimensions, domain, path and title,
so a stale path pushes selection back toward the behaviour this change
narrows. Renamed to `reset-ishandled-only-when-the-value-can-carry-over`,
following the existing precedent for conditional slugs such as
`unreleased-symbol-change-is-not-a-breaking-change`.
- Keywords still listed `initialization` and `deterministic` and omitted
`false-positive`, the tag this repository uses for suppression articles.
Replaced with `carry-over` and `loop-iteration` and added `false-positive`.
- The good sample demonstrated only the "prefer separate fresh locals" clause
and contained no reset at all, so the article's headline case had no positive
example. It was also asymmetric with the bad sample, which gained a loop
procedure showing a local that carries `true` into the next iteration.
Added the matching loop procedure to the good sample: a local declared outside
the loop is reset at the top of each iteration. That case cannot be solved by
introducing another local, because AL has no block scope, so it is the only
shape that demonstrates the reset the article still requires. It also gives the
engine the correct `suggested-code` shape for the loop finding; without it the
one-click fix adapted from the good sample would propose splitting the variable
rather than adding one line.
Also renamed the sample codeunits from "IsHandled Init ..." to
"IsHandled Carry Over ...", and updated the two references to the old slug:
the events leaf skill cue and the events pin in evaluation/review-fixtures.json.
validate_frontmatter.py reports 0 errors; Test-ReviewFixtures.ps1 passes with
32 cases across 16 leaf domains and resolves the events fixture to the renamed
article.
