§Eurostat August 2026 unemployment first print
Resolution target is Eurostat une_rt_m/M.SA.TOTAL.PC_ACT.T.EA21: monthly, seasonally adjusted, total age, percentage of the labour force, total sex, euro area 21 countries. The ledger expected release window is 2026-09-27 to 2026-10-05; the official Eurostat calendar fetch this run gives the August 2026 Unemployment event on 2026-10-01, so I keep the forecast tied to the registered target while using the ledger contractual outer date 2026-10-05 as resolutionDate.

The 23 successive changes have mean -0.004 pp, range -0.1 to +0.1 pp, and 18 of 23 changes are exactly 0.0 pp, so last-print persistence is the strongest simple prior.
Model candidates under thesis_model_candidate_v1: persistence candidate point 6.3, p10 6.2, p50 6.3, p90 6.4, 80% interval [6.2, 6.4], 90% interval [6.2, 6.4], interval_method residual-change sigma rounded to published 0.1 pp, calibration_n 23, train_cutoff 2026-06, walk_forward_MAE 0.022 pp. A trailing-3-month-mean candidate also rounds to 6.3 but has walk_forward_MAE 0.030 pp, so persistence is selected.
Prior/update/interval: prior is last-print persistence at 6.3 from the 2024-07 through 2026-06 official history. Adjustment components: momentum 0.0 pp because the latest four prints are 6.3 after a 6.4 in 2026-02, one-off/policy/current-signal adjustment 0.0 pp because no direct August-specific signal was fetched, weights 100% persistence prior and 0% inside-view adjustment. For the interval, successive changes have sigma = 0.047 pp, so the normal 80% half-width is 1.28*sigma = 0.061 pp; rounding to Eurostat's one-decimal publication precision gives a practical half-width of 0.1 pp and implied bounds 6.2 to 6.4.
Counter-consideration: upside risk would land above the interval if July and August labor-force survey inputs show a genuine deterioration large enough to lift the unemployment rate by more than 0.1 pp from the June persistence level. Downside risk would land below the interval if summer employment gains or denominator effects push the rate below 6.15 before rounding.
Review disposition: accepted the blocking resolver critique by using the registered ledger window end, 2026-10-05, as the contractual resolutionDate while separately preserving the official 2026-10-01 Eurostat calendar event in the reasoning and resolution rule; also clarified that interval bounds are after one-decimal publication rounding.
