Jesper Schulz-Wedde 31b9949235 Strengthen al-code-review execution, propagate suggested-code to leaves, two new KB articles
Driven by a parity comparison between BCAppsBCQuality PR #27 and
BCAppsCampAIRHack PR #162 on byte-identical content:

| | BCQuality | AIRHack |
|--|--|--|
| Total findings | 6 | 10 |
| Performance   | 0 | 4 |
| Security      | 0 | 5 |

Standalone runs of al-security-review and al-performance-review against
the SAME diff produced the expected matches (rimd-on-read-only via
inherent-permissions-minimal-grant; redundant-Get via
avoid-redundant-get-when-record-already-loaded). The miss in the live
run is therefore not a knowledge-coverage gap and not a worklist
filtering issue. It is attention dilution inside the al-code-review
super-skill, which the model collapses into one rolled-up generation
pass on real-size PRs.

Changes:

microsoft/skills/review/al-code-review.md
- New 'Execution discipline (mandatory)' subsection in the Action step
  that explicitly forbids collapsing leaves into one shared reasoning
  pass and requires each sub-skill to walk its Source -> Relevance ->
  Worklist -> Action steps as its own iteration before the next leaf
  starts.
- Self-review pass is now described as the final, mandatory iteration
  with a concrete candidate-category checklist (architecture-level
  smells, error-handling gaps, magic constants, privacy/telemetry,
  resource lifecycle). Returning zero agent findings on a real-size
  diff is explicitly defined as a defect.

microsoft/skills/review/al-{security,performance,privacy,style,
                              upgrade,ui}-review.md
- Each leaf skill now states that when an unambiguous .good.al
  companion exists, findings[].suggested-code should carry the
  literal replacement for the source lines. Closes the
  one-click-suggestion gap created when BCQ#19 only updated
  al-code-review.

microsoft/knowledge/security/case-must-handle-unknown-enum-values.{md,
                                                            bad.al,
                                                            good.al}
- New article: case over a security-sensitive enum (Authentication
  Type, Authorization Mode, Identity Provider, Permission Scope,
  Encryption Algorithm) MUST have an else arm. Without it, an unknown
  enum value silently falls through and the security context never
  initialises. The bad sample is lifted from the SharePoint Graph
  helper that triggered the parity finding.

microsoft/knowledge/performance/instream-length-unreliable-for-bc-
                                                   streams.{md,bad,good}
- New article: InStream.Length returns 0 / partial for HTTP-response
  streams and some file-API streams, breaking size-threshold branching
  in upload code. Bad sample is the simple-vs-chunked Graph upload
  pattern; good sample materialises into a Temp Blob first.

Companion change: microsoft/BCAppsBCQuality#28 extends the
orchestrator's bootstrap prompt with the same per-iteration execution
discipline and adds a CI warning when a >5-file PR returns zero agent
findings (regression signal).

# AL UI and accessibility review
Reviews AL page source and control add-in UI files against the `ui` 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`.
UI findings apply to page files — files that declare `PageType = ...`, including `*.Page.al` under the standard file-naming convention — and to JavaScript/CSS/HTML files that render Business Central control add-ins. The skill returns `not-applicable` when the diff contains no page or control add-in UI changes.
An orchestrator invokes this skill with either a `pr-diff` or a `file-path`. The skill produces a single JSON document conforming to the DO output contract.
## Source
Collect all knowledge files under `*/knowledge/ui/**/*.md`, across every enabled layer.
## Relevance
Apply the frontmatter matching rules defined in READ against the task context:
- `bc-version` — the target BC version from the PR branch's `app.json` or the orchestrator-supplied version. If unavailable, the dimension is `unknown`.
- `technologies``[al]` or `[javascript]`.
- `countries` — the countries declared in the consuming app's `app.json`. If absent, `unknown`.
- `application-area` — pass the actual set declared by the changed objects; do not substitute `[all]`.
Discard files that are not applicable. Retain conditionally applicable files only when the orchestrator's configuration permits them; findings derived from those files MUST have `confidence` no higher than `medium` and MUST name the unknown dimensions in `message`.
## Worklist
Narrow the relevant files to the subset that applies to the changes under review.
- **UI-file filter.** UI review applies to files declaring `page`, `pageextension`, or `pagecustomization`, and to control add-in JavaScript/CSS/HTML that changes rendered UI. When the diff contains no such files, return `outcome: "not-applicable"` without evaluating knowledge files.
- For each relevant knowledge file, compute overlap against changed page declarations and control add-in UI files, weighted toward `Caption`, `ToolTip`, `AboutTitle`, `AboutText`, `OptionCaption`, `ShowCaption`, `InstructionalText`, `GridLayout`, `Style`, `StyleExpr`, action definitions, field-level properties, DOM creation, ARIA attributes, and keyboard/focus handlers.
- Tokens extracted from the diff (`Caption`, `ToolTip`, `AboutTitle`, `AboutText`, `PageType`, `ShowCaption`, `InstructionalText`, `grid`, `fixed`, `GridLayout`, `Style`, `StyleExpr`, `Favorable`, `Unfavorable`, `Ambiguous`, `cuegroup`, `controladdin`, `usercontrol`, `aria-`, `tabindex`, `keydown`, `focus`, `innerHTML`, `createElement`, `&`, `Specifies`, `Message(`, `Confirm(`, `Error(` in a page context, `Disabled`, `Invalid`, `Whitelist`, `Blacklist`, trailing punctuation patterns on captions).
A file enters the candidate worklist when its `keywords` intersect the extracted tokens or its topic matches a changed page element.
Once the candidate worklist is known, resolve layer-precedence conflicts per READ and record suppressions.
When the post-conflict worklist is empty because no applicable UI knowledge exists, or because configuration suppressed every candidate, emit `outcome: "no-knowledge"`. When the worklist is empty because no applicable UI knowledge matched the page changes, emit `outcome: "completed"` with an empty `findings` array.
## Action
For each worklist entry, evaluate the diff against the file's `## Best Practice` and `## Anti Pattern` sections. UI text findings are generally `minor` — they affect localization and polish rather than correctness. Accessibility findings for missing labels, broken grid semantics, semantic color without text meaning, or UI-rendering control add-in changes can be `major`; use `minor` for low-risk manual-review reminders and polish issues.
Set `confidence` to:
- `high` when the detection is based on an unambiguous pattern match (banned term literal, missing "Specifies" opener on a field tooltip, caption exceeding documented limit).
- `medium` when detection relies on heuristics (judging whether a caption is a noun phrase or a sentence phrase) or when any frontmatter dimension was `unknown`.
- `low` when the finding is an advisory derived only from applicability.
When the knowledge file ships an unambiguous `.good.al` companion that names exactly the correction the finding requires (and the diff context makes the substitution mechanical), set `findings[].suggested-code` to the literal replacement for the source lines indicated by `location`. The payload must be a verbatim replacement — no diff markers, no fences, no commentary — that the consumer can render as a one-click suggestion. Skip the field when the appropriate fix depends on context the skill cannot determine, or when more than one defensible replacement exists. See `skills/do.md` for the full contract.
Outcome selection:
- `completed` — the skill evaluated every worklist item.
- `no-knowledge` — no applicable UI knowledge survived filtering.
- `not-applicable` — the diff contains no page, pageextension, pagecustomization, or control add-in UI files.
- `partial` — a budget was hit before the worklist was exhausted.
- `failed` — an unrecoverable error occurred.
