 - The Serene adapter uses Serene's internal saved season state because there is no public per-dimension season-freeze API. The real-client behavior above, including each eternal mode and No Seasons, still needs player verification. Serene's [temperature and precipitation hooks](https://github.com/Glitchfiend/SereneSeasons/blob/1.21.1/common/src/main/java/sereneseasons/season/SeasonHooks.java) only cool eligible biomes.
 - Serene Seasons' [season tick](https://github.com/Glitchfiend/SereneSeasons/blob/1.21.1/common/src/main/java/sereneseasons/season/SeasonHandler.java) advances from a dimension's day-time changes. A Rivencraft Age with a stopped celestial cycle may also have a stopped season; this needs an in-game check.
-- Rivencraft's non-Normal weather modes currently control weather in each Age independently. Their timing can conflict with Serene Seasons' weather-frequency changes. Ecliptic Seasons integration remains issue #39; simultaneous installation is not a supported target.

Ecliptic Seasons integration was closed as unsupported for live dynamic Ages in issue #39; simultaneous installation is not a supported target.
 
 ## Verification so far
 
 `./gradlew build` passed for candidate 0.4.9.2, and the baseline plus archived environment GameTests passed (35 required tests). The archive now covers seasonal page visibility, exclusivity, and saved-plan persistence without Serene installed. With Serene Seasons 10.1.0.8 and GlitchCore 2.1.0.2 in the optional local runtime, the GameTest server previously crashed when Serene Seasons sent `sereneseasons:sync_season_cycle` to a GameTest mock player that had not negotiated its client payload channel. The stack trace originates in Serene Seasons' `SeasonHandler.sendSeasonUpdate`, through GlitchCore's packet handler and NeoForge's packet check. This is a GameTest mock-network limitation, not a completed absent/present compatibility check. Do not keep rerunning that suite with Serene Seasons; use the real-client test path above instead.
 
 For candidate 0.4.10.1, `./gradlew build --offline` and the focused environment archive passed (36 required GameTests). The new regression check covers omitted-page selection, explicit-page precedence, no-Serene behavior, and save/reload. Actual Serene weather, whitelisting, and eternal-season visuals still require the real-client steps above.

+The user subsequently reported an in-game pass for issue #38, recorded in its Gitea comment and release V0.4.9.2. The earlier candidate notes above describe the historical automated checks; the real-client matrix remains useful when upgrading Serene Seasons or GlitchCore.
