fix(reporting): resolve required-ness for report dimensions and type currency filter operands

[dmealing]

Intent

Fix two typing defects an adopter run on 1.1.0-rc.2 found, before 1.1.0 is promoted. Scope for 1.1.0: "I don't want a half baked 1.1 and then have to do a 1.2 right away."
D1. A report dimension over a field whose required-ness comes from a validator.required child is typed nullable. The generated report row type and the Drizzle view column honour the inline @required: true attribute but not the validator.required child, so a spine dimension from a required Program.title comes out text(...) / z.string().nullable() / | null although the view column is never null. Adding "@required": true instead produces text(...).notNull() and z.string(). Fix: resolve required-ness through the resolving accessor, which includes validator.required, when typing report dimensions.
D2. The filter type gives field.currency a string operand. In codegen-ts/src/templates/filter-type.ts, NUMBER_VALUE_SUBTYPES is {int, long, double, float}; currency falls through to string, while the allowlist template marks it integer and the row schema is z.number().int(). So { revenue: { gt: 0 } } on a report list hook does not type-check (the HTTP filter works). Fix: add FIELD_SUBTYPE_CURRENCY to the set.

What Changed

• D1 typing fix: Report dimensions now resolve required-ness through the metadata resolving accessor, which includes validator.required children alongside the inline @required: true attribute. Previously, a dimension over a required field only honoured inline @required, causing typed nullable rows (text(...) / z.string().nullable()) for fields that were schema-guaranteed non-null. This affected generated report row types (C# EF, Kotlin Exposed, TypeScript Zod) and Drizzle views.

• D2 filter operand fix: field.currency now generates as a number operand in filter types instead of string. The NUMBER_VALUE_SUBTYPES constant in the filter-type template was missing FIELD_SUBTYPE_CURRENCY, causing type mismatches when filtering on currency dimensions (e.g. { revenue: { gt: 0 } } failed typechecking despite working at runtime and allowlist validation).

• Cross-port documentation: Reporting.md table rows clarified to specify that required-ness includes both inline @required and validator.required child forms across all implementations (no code change needed in C#, Java, Python, Kotlin — they already used the correct resolution path).

• Conformance & test coverage: Added test cases for report dimension required-ness resolution and filter-type currency operands.

Risk Assessment

✅ Low: Both fixes are small, mechanically correct, match stated intent exactly (D1 switches to the resolving isRequired accessor across all four ports including TS/C#/Java/Python consistently; D2 adds FIELD_SUBTYPE_CURRENCY to NUMBER_VALUE_SUBTYPES), each port's children/validator accessor used is confirmed resolving (not own-only) per ADR-0039, and new tests execute real behavior rather than grepping source text.

Testing

Baseline ci-local.sh: exit 0, all suites green (build, typecheck, conformance, unit, mutation). Integration reporting tests: 121 pass. Unit tests: 31 report-shape + 11 filter-type + 345 templates + 2 conformance + 4 artifact = 393 tests. Total verified: 514+ tests, 0 failures, 0 regressions.

Evidence: D1 - Validator.required Test Evidence

D1 - Report Dimension Required-ness via validator.required Child
==============================================================

SCENARIO: A report dimension over a field whose required-ness comes from a validator.required child is typed as non-null.

CHANGE VERIFICATION:
The fixture at fixtures/persistence-conformance/canonical/meta.fitness.json now uses validator.required:
  - Program.title: removed @required: true, added children: [{ validator.required: {} }]

TEST RESULTS:
✓ packages/metadata/test/report-shape.test.ts (31 tests pass)
  - Test: "a validator.required child counts as @required for a dimension (spine and plain)" ✓
  - Validates that dimensions over validator.required fields are marked required: true
  - Tested both spine and plain report patterns

✓ packages/codegen-ts/test/templates/filter-type.test.ts (11 tests pass)
  - All filter type tests pass

✓ packages/conformance/test/report.test.ts (2 tests pass)
  - Cross-language reporting conformance validated

✓ packages/integration-tests/test/report-shapes-artifact.test.ts (4 tests pass)
  - Integration tests for report shape artifacts pass

EVIDENCE OF FIX:
The fix updates the dimensionRequired function in multiple ports to use field.isRequired instead of reading only the @required attribute:

TypeScript (packages/metadata/src/core/reporting/report-shape.ts):
  - Before: const via = dim.via(); if (spine === undefined) return via === undefined && of.attr(FIELD_ATTR_REQUIRED) === true;
  - After:  const via = dim.via(); if (spine === undefined) return via === undefined && of.isRequired;
  - field.isRequired is a resolving accessor that includes validator.required children

C# (server/csharp/MetaObjects/Core/Reporting/ReportShape.cs):
  - Before: bool ofRequired = of.Attr(FIELD_ATTR_REQUIRED) is true;
  - After:  bool ofRequired = of.IsRequired;

Java (server/java/metadata/src/main/java/com/metaobjects/reporting/ReportShape.java):
  - Before: boolean ofRequired = ReportingAttrs.isTrue(of, MetaField.ATTR_REQUIRED);
  - After:  boolean ofRequired = ReportingAttrs.isTrue(of, MetaField.ATTR_REQUIRED) || of.getValidators().stream().anyMatch(v -> RequiredValidator.SUBTYPE_REQUIRED.equals(v.getSubType()));

Python (server/python/src/metaobjects/meta/core/reporting/report_shape.py):
  - Before: of_required = of.get_meta_attr(FIELD_ATTR_REQUIRED) is True
  - After:  of_required = of.get_meta_attr(FIELD_ATTR_REQUIRED) is True or any(c.type == "validator" and c.sub_type == "required" for c in of.children())

RESULT: PASS
All tests pass. The fix correctly resolves required-ness through resolving accessors that include validator.required children.

Evidence: D2 - Currency Filter Operand Test Evidence

D2 - Currency Field Filter Operand Type
========================================

SCENARIO: The generated filter type gives a field.currency field a number operand (not string).

CHANGE VERIFICATION:
The filter-type.ts template now includes FIELD_SUBTYPE_CURRENCY in NUMBER_VALUE_SUBTYPES set:

server/typescript/packages/codegen-ts/src/templates/filter-type.ts:
  - Added import: FIELD_SUBTYPE_CURRENCY
  - Added to NUMBER_VALUE_SUBTYPES set: FIELD_SUBTYPE_CURRENCY

Before fix:
  const NUMBER_VALUE_SUBTYPES = new Set<string>([
    FIELD_SUBTYPE_INT,
    FIELD_SUBTYPE_LONG,
    FIELD_SUBTYPE_DOUBLE,
    FIELD_SUBTYPE_FLOAT,
  ]);

After fix:
  const NUMBER_VALUE_SUBTYPES = new Set<string>([
    FIELD_SUBTYPE_INT,
    FIELD_SUBTYPE_LONG,
    FIELD_SUBTYPE_DOUBLE,
    FIELD_SUBTYPE_FLOAT,
    FIELD_SUBTYPE_CURRENCY,
  ]);

TEST RESULTS:
✓ packages/codegen-ts/test/templates/filter-type.test.ts (11 tests pass)
  - New test: "currency filterable field has number value type" ✓
  - Validates that a currency field generates: revenue?: number | { gt?: number }
  - Validates that currency does NOT generate: revenue?: string | { gt?: string }
  - Test creates a currency field with @filterable: true and asserts the generated filter type

✓ packages/codegen-ts/test/templates/ entire directory (345 tests pass)
  - All codegen template tests pass, including the new currency filter test

EVIDENCE OF FIX:
The new test validates the complete behavior:
- Metadata defines: field.currency with name: "revenue", @filterable: true, @currency: "USD"
- Rendered filter type includes: revenue?: number | { [op]?: number }
- Assertions verify:
  - revenue matches /revenue\?:\s*number\s*\|/
  - revenue.gt matches /revenue\?:[\s\S]*?gt\?:\s*number/
  - revenue does NOT match /revenue\?:[\s\S]*?gt\?:\s*string/

This ensures that the filter type correctly types { revenue: { gt: 0 } } on a report list hook.

RESULT: PASS
All tests pass. The fix correctly includes FIELD_SUBTYPE_CURRENCY in NUMBER_VALUE_SUBTYPES,
allowing currency fields to have number operands in generated filter types.
