 ## Implementation Notes
 
-- TB and HAZWOPER recency checks use explicit procedure-code filtering in CQL so the seeded in-memory CQF evaluator can resolve the most recent exam date without relying on unsupported value-set token retrieval.
+- All 8 active CQL measures now use inline code-filter expressions on both the qualifying event (Procedure or Immunization) and the enrollment/exemption Conditions, matching the system/code stamped by `SyntheticFhirBundleBuilder`. This replaces the earlier `exists([Condition])` / `Count([Condition]) > 1` pattern that was semantically correct but not code-scoped. True ValueSet token expansion (resolving `urn:workwell:vs:*` OIDs via the VSAC or a local expansion service) is a known evaluator limitation of the in-memory CQF path; the inline-code pattern is the stable workaround until a resolver is wired.
 - All four HEDIS wellness measures are seeded via `ensureInstanceSeeds()` when `WORKWELL_INSTANCE=ecqm` or `twh`.
 - All 49 CMS eCQM catalog entries (2026 performance period) are seeded via `ensureCmsEcqmCatalogSeed()` for the same instance values. They are Draft-only and do not participate in CQL evaluation runs until CQL is authored and compiled. On re-seed, existing measures are looked up by CMS ID prefix (`LIKE 'CMSNNNv%'`) and updated in-place so version bumps (e.g., v13→v14) do not create duplicate DB rows.
