Subject: [PATCH 1/3] Add Utah CCAP Table 4 copay and income limits effective
 October 1, 2026

Encode the DWS Table 4 "Child Care Income Eligibility and Co-Payment"
edition effective October 1, 2026 as a 2026-10-01 layer in the copay
amount and income group upper-bound parameters (household sizes 2-12+,
income groups 1-16, all child-count columns). The existing 2020-01-01
layer keeps the April 1, 2026 edition at the backdating floor.

The October edition prints 0 (previously n/a) in the structurally
impossible child-count cells; the repeat-padding convention is retained.
The size 10 group 16 bound is encoded as published (12,846) with a
comment noting the apparent typo for 12,486; it has no behavioral
effect. The new entry/exit eligibility structure (groups 6/10/16) is
noted but not modeled here.

Part of #9365.

 # Each value is the inclusive upper bound of a countable income group;
 # income above a group's upper bound falls in the next group. Household
 # sizes run from 2 (the smallest possible unit, one parent and one child)
 # through 12, where the size 12 column covers households of 12 or more.
 # Group 16 is the maximum income range to qualify for child care
-# assistance (85% of the state median income). The published lower bound
-# of household size 5 group 3 reads 3,644.01, an apparent typo for
-# 3,664.01, since the size 5 group 2 upper bound is 3,664; only upper

+# published lower bound of household size 5 group 3 reads 3,644.01, an
+# apparent typo for 3,664.01, since the size 5 group 2 upper bound is
+# 3,664; only upper bounds are encoded here (the October 2026 edition
+# similarly prints the size 6 group 16 range as 10,940-11,445, omitting
+# the usual .01 lower-bound offset). The October 2026 size 10 group 16
+# bound is encoded as published (12,846), although the uniform steps of
+# the surrounding sizes (size 9: 12,225, size 11: 12,746, size 12:
+# 13,006) suggest 12,486 was intended; the group 16 bound only separates
+# group 15 from group 16 in ut_ccap_income_group, so the discrepancy has
+# no behavioral effect.
+#
+# The October 2026 edition also introduces entry and exit eligibility
+# thresholds (entry at group 6 for applications, exit at group 10 for
+# reviews, and open child care at group 16 between review cycles); that
+# structure is not yet modeled in ut_ccap_income_eligible.

Subject: [PATCH 2/3] Update UT annual subsidies test for the October 2026
 copay layer

The 2026 annual case now spans two Table 4 editions: nine months at the
April 2026 copay (791/month) and three at the October 2026 copay
(826/month, since the uprated bounds move the household from income
group 5 to 4), totaling 9,597.

Subject: [PATCH 3/3] Address UT Table 4 review nits

Adds the reviewer-requested October-layer tests (padded n/a cell,
size 12 group 16 far corner, size 4 and size 10 group 15/16 boundary
pairs documenting the as-published 12,846 bound), tightens the n/a-cell
header comment in amount.yaml, and swaps the April 2026 citation to an
archived capture of the Infosource page (verified to show the April
edition), since Utah overwrites the live page at each reissue and
publishes no date-stamped April PDF. The entry/exit eligibility tiers
are tracked in #9372.
