Four open questions were scattered inline in builder.md and the POC
findings doc. Moved them into the central OQ tracker under
docs/architecture/questions/ and updated the index:
- OQ-004: Discriminator::Field name type (&str vs String) — raised in
builder.md during ADR-009 spec drafting
- OQ-005: Union materialization shape (byte-offset vs field-name
consistency) — raised in the POC findings
- OQ-006: Builder spec Example 3 wrap Union in Struct — raised in the
POC findings (doc fix; engine requires AlkType:Struct at top level)
- OQ-007: Bytes materialization lossy UTF-8 — raised in the POC
findings (blocks SFTP use case for validate_bytes)
Index updates:
- open-questions.md: new 'Schema Construction' and 'Validation' theme
groups; new 'Open' section for active investigation targets (distinct
from 'Deferred / Blocked' which holds scope-parked OQs)
- README.md: OQ table extended with OQ-004 through OQ-007
- builder.md: inline OQ-004 replaced with a tracker reference
- findings.md: inline OQ-005/006/007 replaced with tracker references
Doc-only change; 369 tests pass.
