What Changed

• Adds metamodel vocabulary across the ports: validator.exactlyOne, @constraintName, @condition, field.duration, @sequenceStart (the counter is never moved on an existing sequence), @dbSetName (C#-only, via a new port-scoped ports field in the registry), and the pascal column rule. validator.atLeastOne no longer takes @max; upgrading adopters must switch to validator.exactlyOne and remove the @max.
• Lets an @intValueMap enum be an array (ERR_ENUM_INT_VALUE_MAP_ARRAY removed). TypeScript and Python map elements on write and read; C# emits working array converters; Java and Kotlin refuse or defer the case, recorded in KNOWN_GAPS.md. C# durations need "wire": { "durations": "iso" } to keep ISO-8601 output.
• Adds named naming strategies ("naming": { "columns": "<name>" }) that each port's application can register, plus shared conformance fixtures and persistence/api-contract scenarios for these changes.

Known limits

• Kotlin: the Exposed table generator emits a scalar column for an enum array, so generated code for an int-backed enum array does not compile yet. The compile gates leave out IntEnumArrayController.kt and its repository files. This gap predates this PR; see KNOWN_GAPS.md.
• The reserved-vocabulary changes are not in this PR. They land in a follow-up together with the Java, Kotlin and Python registry catch-up.

Gate

Validated in 2 no-mistakes runs. Run 1 passed. After it, the hosted csharp check failed: the golden tests found their files through [CallerFilePath], and a CI build (CI=true turns on ContinuousIntegrationBuild) maps source paths to /_/. Run 2 validated that fix (the golden files are now found from the repo root). Run 2's test step ended with an approved exception. Its live scenarios drove TypeScript only. Every port's full suite, including the integration suites, ran to completion locally before the pipeline. Hosted CI re-runs every port on this push.

Validation

Risk Assessment

⚠️ Medium: Re-review found no defect: the only change since the starting head is a wording fix in CHANGELOG.md, and my spot checks of the earlier fix rounds held up. The change is still very large (367 files across five ports), and I read only the paths listed below, so medium reflects scale rather than a known problem.

Testing

Baseline ts-fast and ts-unit passed earlier. Live Postgres scenarios pass in TypeScript: enum @default on create, int-backed enum array round-trip, @Schema on reads and writes (with the same-name table scenario), and @sequenceStart never moving the counter. A runtime mutation dropping @Schema on insert was caught and reverted. Not finished: the full integration-tests regression was stopped before it reported, and C#, Java, Kotlin and Python ports were not driven live. Verdict is inconclusive.

• Live validation: ⚠️ inconclusive - 5 of 9 scenarios driven live against the product

• ℹ️ server/java/codegen-kotlin/src/main/kotlin/com/metaobjects/generator/kotlin/KNOWN_GAPS.md:231 - Admitting @intValueMap + isArray in every port leaves Kotlin with a build-time failure in place of the old load-time error. KotlinExposedTableGenerator.enumColumnSpec emits a scalar column for any enum array, string-backed or int-backed. The generated controller then fails to compile, and the fitness corpus' IntEnumArrayController.kt is left out of the compile gates. Java OMDB refuses an int-backed array at runtime on write and read. KNOWN_GAPS.md and docs/ports/kotlin.md describe this honestly. The CHANGELOG line "Kotlin's Exposed generator emits no enum array column" is looser: it emits a scalar column and the build fails. Fixing it means adding an Exposed array column, which is a feature beyond this replay. Recorded as a known, documented gap, not a blocker.

⚠️ **Test** - 3 issues (1 error, 2 warnings)

• 🚨 server/typescript/packages/integration-tests - Full integration-tests regression (bun test in server/typescript/packages/integration-tests) never completed. I stopped it, so the log has no pass/fail summary and ends with exit=143. A later task notification reported the wrapper as exit code 0, but that is the wrapper's status after the kill, not a test result. Rerun it to a finished summary before deciding.

⚠️ **Document** - 1 info

• ℹ️ Pre-existing C# and Kotlin source comments on main still cite internal rulings by date (e.g. "Owner ruling 2026-09-20" in M2MNavigation.cs, M2MUnpairedJunctionLoadErrorTests.cs, EntityGenerator.cs, requirements ruling in RequirementConstants.cs). This change did not add them, so they are out of scope. Follow-up: one sweep that replaces ruling identifiers with the rule itself across code comments.
