Cause

IntentParser.validateRelatedShow checked every show: name against the source's authored fields and relations only. The audit columns audit: true adds (CreatedAt, CreatedBy, UpdatedAt, UpdatedBy) were refused:

entity [Customer] related [SupportTicket] show references [CreatedAt] which is not a field or relation of [SupportTicket]

The generator already handled them: EdmIntentGenerator.relatedColumns resolves show: against the source's built properties, which include the audit properties, and the source's /search (what the register reads) returns them.

Change

• IntentParser.validateRelatedShow: when the source is audit: true, the four audit names are known show: names, matched case-insensitively like every other entry. On a source without audit: true they are still refused, now with a message that names the flag: [CreatedAt] is an audit column, and [SupportTicket] is not audit: true.
• No generation change. An audit timestamp property carries TIMESTAMP / DATETIME-LOCAL, and ModelParameterProcessor.relatedColumn derives the register's date: true from the type (TIMESTAMP → Date), so the column renders as a date-time. CreatedBy / UpdatedBy (VARCHAR) render as text. Models that show no audit column generate exactly as before.
• Cross-model registers (model:): the parser never validates their show: names, because the source lives in another model it cannot see. The generator resolves them against the owner model's .model, which carries the audit properties when that source is audited. Nothing to change there.
• intent-assistant-guide.md: the related rules now say an audit source's four audit columns may be shown.

Verification

• New parser tests (IntentParserTest): anAuditSourcesCreatedAtAndCreatedByMayBeShown, anAuditColumnOfANonAuditSourceIsRejected (asserts the message), anUnknownShowEntryIsStillRejected (only the unknown name is reported).
• New EDM test relatedShowCarriesTheAuditColumnsOfAnAuditSource: the register's CreatedAt column is TIMESTAMP / DATETIME-LOCAL, and CreatedBy is VARCHAR / TEXTBOX.
• New ModelParameterProcessorTest.aRegisterColumnOverAnAuditTimestampRendersAsADate: the audit timestamp column gets date: true, and the audit user column gets no date, number or lookup flag.
• IntentEmissionCoverageIT (generates, compiles and runs the app) gains a Person → Claim register over the audited Claim with show: [note, CreatedAt, CreatedBy]. It asserts the generated Person.related.js columns (CreatedAt has date: true, CreatedBy is plain text) and that the register's own call, POST ClaimController/search with equals: { Person: 2 }, returns the delegated claim with CreatedAt set and CreatedBy = admin. Green locally on H2.
• Full engine-intent (1797) and ide-template (310) unit suites green; mvn -T 1C formatter:validate green with the formatter cache wiped.
