BITESIZE READING LIBRARY V4.5.0 — STANDARDS COVERAGE BUILD STATUS
16 September 2026

IMPLEMENTED
1. Catalogue-driven standards authority.
2. Exact Product ID matching with no standards title inference.
3. Verified-only filtering.
4. Addressed -> Practised -> Assessed hierarchy.
5. Cached catalogue snapshot support through existing live catalogue cache.
6. Generic framework/master-standard ingestion.
7. In-memory indexes for Product ID and standard lookup.
8. Individual-resource standards state and drill-down.
9. My Library Standards Coverage dashboard.
10. Filters by framework, grade, strand/group, alignment level, resource type, text type and standard query.
11. Standard -> installed resource drill-down.
12. Gap recommendations using verified catalogue products not already matched in My Library.
13. Legacy title-derived matches blocked from standards until explicit confirmation.
14. Unknown future frameworks fail safely.
15. Existing V4.4 local standards.js and standards-alignments.js runtime dependency removed.

VALIDATED WITH SYNTHETIC CATALOGUE FIXTURE
- Verified resource contributes coverage.
- not_reviewed product does not contribute.
- Assessed increments Addressed + Practised + Assessed.
- Unconfirmed legacy title match does not count as Product ID standards ownership.
- Missing RI.4.9-like gap can surface a verified non-installed catalogue recommendation.
- Future unknown framework is indexed without crashing.
- JavaScript syntax passes node --check.

LIMITATION OF THIS BUILD SESSION
The published https://bitesize-education.com/updates/catalog.json endpoint could not be reached from the build environment, so the live production schema could not be directly inspected. The reader is intentionally schema-tolerant around the documented fields and should be tested against the next real Catalogue Manager export.

LEFT TO COMPLETE BEFORE PRODUCTION SIGN-OFF
- Test against the actual current Catalogue Manager catalog.json export.
- Confirm exact field names/shapes and adjust adapter aliases if needed.
- Populate/verify real product alignment data in Catalogue Manager.
- Test with a representative installed library containing modern and legacy resource packs.
- Validate Windows/Chromebook/Mac browser behavior, including a successful live sync followed by offline restart.
- Regression-test Discover thumbnails, search, Trending, Recently Added, resource import, Reading Text, Presentation, Reading Framework, Assessment, persistence, update system and UK/US localisation on target devices.
