The per-child entity ids are derived from the child name by Home
Assistant's real slugifier, which transliterates every script through
unidecode; the hand-rolled Latin-only mirror in sensor.py dropped
non-Latin characters instead (slugging 京子 to "unknown"), so the
roster's slugs diverged from the actual entity ids and the
party-board/strategy auto-discovery silently failed for non-Latin
households.
Use homeassistant.util.slugify at runtime, composing the registry's
64-character entity-id cap the roster needs (verified against HA
2024.6: slugify itself does not truncate; the entity registry
truncates the full <domain>.<slug> id). Give the mock harness a
faithful homeassistant.util.slugify stub — python-slugify's frozen
legacy pipeline with unidecode, verified byte-for-byte against real
python-slugify across Latin, Cyrillic, CJK and Greek name shapes —
and cover the non-Latin resolution contract in tests (roster slug ==
the object id HA's entity-id derivation produces).
Feature-review finding (P2): auto-discovery slug must match Home
Assistant's real slugify.
Iterates present children from the Feature 10 presence sensors, lists
what each owes today from the remaining sensor, omits absent children
entirely. Blueprint inputs (time, notify service, send toggle); the
notify target is the household's choice, never hard-coded. PyYAML and
Jinja2 join the dev-only dependencies for blueprint template tests.
