+# Classify every field with DataClassification
+
+## Description
+
+Every field on every AL table and table extension must have a resolved `DataClassification` value, either declared directly on the field or inherited from a table-level default. The value drives GDPR tooling, data-subject requests, retention policies, and audit reporting — all of which rely on the field metadata to know what data to include, anonymize, or delete. A field with no field-level property and no table-level default resolves to `ToBeClassified`, which is a compliance gap, not a neutral state.
+
+## Best Practice
+
+Choose the narrowest value that accurately describes the field's content: `EndUserIdentifiableInformation` for data that directly identifies a person, `EndUserPseudonymousIdentifiers` for indirect identifiers, `CustomerContent` for business operational data, `SystemMetadata` for system-generated housekeeping, `AccountData` for tenant/billing, `OrganizationIdentifiableInformation` for organization-level identifiers. Use a table-level default for homogeneous tables, and override individual fields whose content differs from that default. When uncertain between two values, pick the stronger protection.
+
+See sample: `classify-every-field-with-dataclassification.good.al`.
+
+## Anti Pattern
+
+Leaving `DataClassification = ToBeClassified` on a field, omitting classification when the table has no default, or relying on a table-level default that understates a field's actual content. Code in this state fails compliance audits and breaks the subject-access-request and retention tooling that depends on the property being set correctly.
+
+See sample: `classify-every-field-with-dataclassification.bad.al`.

+
+> Contributions welcome — open a PR to refine or extend this article.
+
+## Description
+
+The `IncludedPermissionSets` property lets one AL permission set reference another, composing rights out of smaller building blocks. Combined with `Assignable = false` on the building blocks, an extension can ship focused per-module units (a table-data cluster, an API-access cluster) and assemble role-shaped sets that include them. Adding an object updates one building block, and every role-shaped set that includes it inherits the change automatically — instead of drifting apart across duplicated definitions.
+
+## Best Practice
+
+Break permission grants into small, focused building blocks, one per cohesive concern. Mark the building blocks `Assignable = false` so administrators do not accidentally assign a fragment. Build role-shaped, `Assignable = true` sets that reference the relevant building blocks through `IncludedPermissionSets`. When the extension grows, the structure absorbs the growth without duplicated edits.
+
+See sample: `compose-permission-sets-with-included-sets.good.al`.
+
+## Anti Pattern
+
+Declaring several role-shaped permission sets that each re-enumerate the same object lists. Adding a new table means touching every set by hand; the sets drift apart over time, and subtle authorization bugs appear where one role was updated and a sibling role was not.
+
+See sample: `compose-permission-sets-with-included-sets.bad.al`.

+# Do not widen access to expose sensitive data through a public API
+
+## Description
+
+Every member you make publicly reachable becomes a contract you must keep — and when that member returns a secret, the contract leaks the secret. Widening access to a credential happens in several shapes: a public getter that returns a raw token or password, an event whose parameter carries a secret to every subscriber, or a global variable holding a key that an extension can read. Once such a surface ships, removing it is itself a breaking change, so the exposure is hard to walk back. Sensitive material — tokens, passwords, connection secrets, `SecretText` values, security internals — must stay inside `internal` or `local` members. Public surfaces should expose only non-sensitive business data. LLMs often add a convenient `GetToken()` getter without recognizing it as a permanent security boundary breach.
+
+## Best Practice
+
+Keep secrets in `internal` or `local` members, and prefer the `SecretText` type so the value cannot be read back or logged. Where callers genuinely need a credential, pass it inward (a setter) rather than handing it outward (a getter). Public API should return only non-sensitive data — a masked reference, a status, a business identifier — never the raw secret. Treat each public member as a lasting commitment and keep the security-sensitive surface as small as possible.
+
+See sample: `do-not-expose-sensitive-data-through-public-api.good.al`.
+
+## Anti Pattern
+
+A public `GetAccessToken()` that returns the raw token (or an event parameter carrying a credential to all subscribers), turning a secret into a de-facto public API any dependent can consume. Detection: a non-`local` procedure, event parameter, or global variable that surfaces a token, password, key, or other credential. Keep the secret internal and expose only non-sensitive data.
+
+See sample: `do-not-expose-sensitive-data-through-public-api.bad.al`.
