engine/extensions/struct.py: ext.struct (typed records) — in-text frontmatter parse + ON_WRITE validation (allowed-fields, content-preserving), ON_READ tags PageShape.TYPED_RECORD, ON_PROFILE raises structured-payload. Proves the framework: feature absent when off (opaque prose, honest profile), present + profile-reflected when on; works through InformationSpace edit. SCOPE updated. 6 tests, 107 total, ~97% coverage, pyflakes clean. Marks T6 + SHARD-WP-0014 done. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
