Cookie reference

The Web SDK uses a different cookie family than AppMeasurement, so your consent banner's cookie inventory needs re-teaching.

AMCV_<org>Legacy, ECID store; read by idMigrationEnabled during transition
s_sqLegacy, Activity Map clicks; retired under Web SDK
demdexLegacy third-party, cross-device / CORE ID
kndctr_<org>_identityWeb SDK, ECID, always first-party on your domain
kndctr_<org>_consentWeb SDK, consent preference; written regardless of choice
kndctr_<org>_clusterWeb SDK, Edge region routing

For your migration: add the kndctr_* family to your CMP[9]'s categorisation and retire the obsolete legacy entries for migrated scopes.
