Use the exact 2016 poverty-guideline rows for SNAP's FY2017 income standards. The USDA original, pages 1–2 covers October 1, 2016–September 30, 2017. For three people in the contiguous states, the ordinary monthly gross/net standards become $2,184/$1,680 rather than $2,189/$1,684 from the linear approximation.

The SNAP total now calls #10886's shared table-aware helper inside its enabled window. The October selector, Guam/VI mapping, two-value increment interface and income-standard comparison/rounding logic remain. Above eight people, the existing separately rounded increments still apply. Other guideline years and unsupported sizes retain their original monthly arithmetic; overriding snap_fpg continues to determine the standards.

Validation:

• Genuine source-boundary and actual-wage gross-test failures preceded the production change. The corrected gross-only RED is separately recorded from the first vector-fixture error.
• All 60 focused cases passed in one capped process (26.53 seconds): 42 original owned cases, nine unchanged TANF-noncash consumer cases and nine new cases. The new vectors cover all 48 published base standards, six increments, boundaries, cutoff dates and geography/fallback controls.
• make format passed with all six frozen hashes unchanged. No partner test changed.

The actual-wage case checks the ordinary gross predicate at $2,185 monthly; it does not establish final SNAP loss through every categorical or exemption route. This verifies the stated FY2017 ordinary standards, not all historical SNAP or state BBCE rules.

WIP: stacked on #10886. Required independent Opus Subfleet review is queued as 20261113-201535-history-snap-fpg2017; no completed review is claimed. Parent merge and current-head CI remain.

axiom: TheAxiomFoundation/rulespec-us#2224 — queued; source admission, authorized signed encoding and parity execution remain pending. Related to #10888's broader consumer audit; this addresses its SNAP subset only.
