+"""Admin-plane presence route tests (task e4a9d31b).
+
+These tests exercise the admin plane's presence routes against the ASGI
+app with httpx, reusing the shared local-RSA-key/stubbed-JWKS harness
+(:mod:`tests.admin_jwt_harness`) so an admin JWT genuinely
+authenticates — signature, issuer, audience, expiry and the
+nestquest-admins group — with NO network access.
+
+Every done-condition case is proven against the DATABASE and the DOMAIN,
+read through the SAME core copy the app uses (``nestquest_core.*``; see
+the two-copy caveat in api/nestquest_core.py):
+
+- Authentication runs through the router's ONE ``require_admin``
+  dependency: an admin JWT passes, a JWT without the group is 403, an
+  absent credential is 401 — and nothing is written.
+- ``PUT /api/v1/admin/children/{id}/presence-schedule`` UPSERTS: the
+  first set persists the schedule, setting again REPLACES it — one
+  schedule row per child, never a duplicate.
+- ``POST /api/v1/admin/presence-overrides`` creates the override (its
+  ``id`` comes back) and ``DELETE /api/v1/admin/presence-overrides/{id}``
+  removes it again.
+- The child's RESOLVED presence changes accordingly: the pure
+  :class:`~nestquest_core.presence.PresenceEngine` built from the
+  stored rows answers differently before/after each write — a schedule
+  restricts the child's present weekdays, an override beats the pattern
+  for its range, and deleting the override restores the pattern's
+  answer.
+- The regeneration side effect lives in the core layer the route
+  calls: setting an all-absent schedule through the route deletes the
+  child's future open quest instances and they are NOT rebuilt while
+  the child is absent every day — the same proof the HA service test
+  makes, through the API instead.
+
+Error mapping (documented in api/routes_admin.py): a core ValueError
+for a non-existent child (schedule or override create) or override
+(delete) is 404; every other core ValueError — a rejected schedule
+(cycle length, pattern coverage, anchor date) or override (malformed or
+inverted dates, an overlapping range) — is 422, the same failure class
+FastAPI reports for malformed bodies.
