SnowSignal
+
Know before the bell.
+
+
+ A transparent, deterministic snow-day and school-delay estimator. Client-only,
+ no tracking — weather by Open-Meteo, US winter alerts by NWS. Every result is an
+ estimate, never an official closure announcement.

Subject: [PATCH 3/3] Prepare SnowSignal v1.0.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Bump the version to 1.0.0 in package.json, the in-app About tab, and the test
guard; add the v1.0.0 changelog entry (keeping all beta history); move README
and ROADMAP from beta wording to stable-release wording; add favicon/manifest
and no-debug-log regression guards. Stable still means estimate — never
official closure data.

+All notable changes to SnowSignal are documented here. Versions follow
+[semantic versioning](https://semver.org).
+
+## [1.0.0] — 2026-07-04
+
+The first **stable release**. SnowSignal remains what it has been through the betas —
+a transparent, deterministic, fully static, client-only estimator with no tracking —
+now with a smarter engine, a finished UI, and a full accessibility and compatibility pass.
+Every result is still an estimate, never an official closure announcement.
+
+### Engine
+- **Refreeze detection** — a wet prior evening followed by a below-freezing commute now
+ registers as black-ice risk: it raises the closure estimate, feeds the delay profile
+ strongly (the textbook "2-hour delay to let crews treat roads"), and counts as a real
+ winter hazard in the plausibility gate.
+- **Trend into school start** — a storm winding down before buses roll now *lowers* the
+ closure estimate (crews get a clearing window) and nudges toward a delay instead; one
+ ramping up into the commute raises it. Gated by storm presence so clear days are unaffected.
+- **Snowfall intensity** — heavy hourly bursts (approaching 1"/hr) score higher than the
+ same total spread thinly, because plows can't keep up with bursts.
+- **Sharper confidence** — confidence now drops when the precipitation type is genuinely
+ ambiguous near the freezing line, and rises when several independent strong signals
+ (snow totals, ice, an official alert, dangerous cold) agree. Tooltips explain what each
+ confidence label means.
+- **Plain-language drivers** — each result surfaces the top 2–4 reasons behind the number,
+ including the biggest factor holding it *down*.
+- **Window fix** — the 5 AM and 9 AM boundary hours were counted in two forecast windows
+ at once; buckets are now disjoint (overnight 6 PM–4:59 AM, commute 5–8:59 AM, daytime
+ 9 AM–5 PM).
+
+### UI
+- Factor breakdown is now grouped under **"Raising the estimate" / "Lowering the
+ estimate"** headings, so direction never relies on color alone.
+- Probability dials gained a subtle halo; the wordmark a restrained accent sweep.
+- Settings modal: more breathing room between groups, clearly marked selected pills
+ (check mark + stronger ring), a separated **"can't be undone"** zone for destructive
+ actions, and a finished About tab with the app mark, tagline, and description.
+- The hourly timeline is keyboard-focusable and scrollable.
+- Added a static `manifest.webmanifest` + theme-color and social-sharing meta tags, a
+ `
