Ex parte share measures how much of the renewal burden the state carries instead of the beneficiary. It trends with data-matching infrastructure, which improves in vendor-release steps rather than smoothly.
Latest 74.2 (02/26); mean monthly change over trailing window 0.19pp; damped six-month projection = 74.8.
Half-weight trend continuation with volatility-scaled uncertainty; renewal cohorts differ month to month, so the interval is wider than the point trend alone would suggest.

Draft is publishable after tightening one resolver ambiguity and addressing the circularity risk from using the registered prior values as evidence.
- warning coherence: The reasoning says repo lookup fetched the registered prior point and interval, which exactly match the final forecast, creating a circularity concern even though the later calculation is independently described.
- warning resolver: The resolution rule adds an exception for CMS corrections before the same release day ends, which slightly weakens the canonical first-print rule and may create timezone or cutoff ambiguity.
- info optional_suggestion: Mention whether March 2026 was unavailable for this exact ex parte field or intentionally excluded, since the official release page had March 2026 preliminary data.
disposition accepted: Review disposition: accepted the critique to remove circular use of catalog prior point and interval by treating the repo lookup only as target registration, and accepted the resolver critique by removing the same-day correction exception. Also clarified that the interval width is a judgmental widening from observed moves and that March 2026 was not used as an exact-series point.

The resolver is a Colorado state row, not a national weighted average: the original first-publication August 2026 reporting-period row in the CMS eligibility processing dataset. The target is the share of completed renewals processed ex parte, reported in percent and rounded to one decimal.
Base-rate/reference-class anchor: the most relevant outside view is Colorado's own post-unwinding first-print run from July 2025 through February 2026. The five inspected points average 74.82 percent and stay within a 73.1 to 76.9 range, so I use state-level persistence rather than a national ex parte average.
March 2026 note: the official Medicaid.gov release page had preliminary March 2026 release context, but the exact Colorado original ex parte renewal-share field used for this target was not included in the inspected local first-print history, so I did not add a March 2026 exact-series point.
Level, momentum, one-off, and mechanism split: level is a mid-70s state process; momentum is nearly flat after alternating monthly moves; one-off renewal cohort mix can shift the share several points; mechanism is stable data-match and eligibility-system automation, with no checked Colorado-specific shock implying a step change by August 2026.
Prior/update/interval: prior model is Colorado latest-value persistence blended with the local historical mean, using the available inspected first-print sample 2025-07, 2025-09, 2025-11, 2026-01, and 2026-02. Starting from latest 74.2, I add +0.3 pp for reversion toward the 74.82 sample mean and +0.3 pp for mild CMS compliance/automation drift, giving 74.8. The 80% interval is judgmentally widened from realized inspected first-print moves up to 3.8 pp to about +/-6.3 pp for six-month cohort, missing-month, and reporting uncertainty.
Counter-consideration: upside outside the interval would require a real Colorado data-match or eligibility-system improvement that lifts the ex parte share above 81 percent. Downside outside the interval would require a manual-heavy renewal cohort, data-source outage, or operational regression pushing the share below 68.5 percent.
Point calculation: latest 74.2 percent plus +0.3 pp mean reversion toward the 74.82 percent local sample average plus +0.3 pp for mild policy/automation drift equals 74.8 percent after rounding. Interval calculation: 74.8 - 6.3 = 68.5 and 74.8 + 6.2 = 81.0, rounded to one decimal.
Resolution-date note: the official CMS page verified the monthly release vehicle and the June 26, 2026 current update, but did not expose a future dated August 2026 state-row placeholder during this fast run. I keep the forecast tied to the canonical ledger date 2026-12-15 and bind resolution to the first official CMS dataset print.
