The /samples/ top-level tree is replaced with sibling files in each
knowledge-layer folder. An article and its demonstrations now live
side-by-side:
microsoft/knowledge/<domain>/<slug>.md
microsoft/knowledge/<domain>/<slug>.good.al
microsoft/knowledge/<domain>/<slug>.bad.al
Rationale:
- Proximity. An article and its paired samples are one unit; the
filesystem now reflects that.
- Layer ownership. Samples inherit layer precedence for free -- a
/custom/ fork can override an article and its samples atomically,
which the shared /samples/ tree previously made awkward.
- Trivial migration path. Action-skill source globs
(*/knowledge/<domain>/**/*.md) are unchanged; sample discovery is a
sibling-filename lookup.
Changes:
- git mv of all 65 sample files from samples/<domain>/<slug>/{bad,good}.al
to microsoft/knowledge/<domain>/<slug>.{bad,good}.al (history preserved).
- Update See-sample references in all 37 articles that ship samples.
- skills/read.md: replace the no-code-blocks bullet with a pointer to a
new Sample files section that fully specifies the sibling convention,
the kinds (good/bad + forward-compatible), multi-technology rules,
demonstration-only status, and layer-precedence behaviour.
- skills/write.md: update the samples pointer to match.
- README.md: annotate the knowledge tree with the sample sibling shape.
- samples/README.md deleted; content lifted into skills/read.md.
- Both generators (C:\temp\gen_performance_knowledge.py,
C:\temp\gen_security_knowledge.py) updated to emit at the new paths
and to stop writing samples/README.md. Re-running them is idempotent
against the committed layout.

Prefer direct record access over RecordRef where possible
Seed article. Converted from an existing performance-review prompt to bootstrap the BCQuality performance corpus. Domain stewards should expand, restructure, and refine as needed.
Description
RecordRef and FieldRef are the platform's reflection API: they work across tables the compiler does not know at authoring time. That flexibility costs per-operation overhead — every field access goes through a lookup — and loses compile-time type checking. For operations where the table is known, a strongly-typed Record variable is simpler and faster.
Best Practice
Use Record variables for code paths that target a known table. Reach for RecordRef and FieldRef only when the table is genuinely dynamic (generic export/import, field-agnostic utilities, cross-table integrations).
See sample: prefer-direct-record-over-recordref.good.al.
Anti Pattern
Using RecordRef as a habit, even when the target table is hardcoded two lines earlier, costs performance and hides intent from reviewers.
See sample: prefer-direct-record-over-recordref.bad.al.
