KrepAPI (Mod)

Added

Client update checks, download flow, and in-game update UI

• UpdateChecker (both fabric-1-21 and fabric-26-1): On client startup, asynchronously fetches .system/mod/versions.json from GitHub, resolves the latest mod version and the JAR filename for the running Minecraft version, compares semver against the installed mod using KrepapiBuildVersion (:protocol), and loads every listed version’s changelog markdown from .system/mod/changelog/{version-with-dashes}.md into versionList + allChangelogs for the menu.
• UpdateDownloader: On explicit user action only, downloads the update JAR over HTTP into mods/KrepAPI-update-{latestVersion}.jar with a volatile progress field; guards against overlapping downloads; surfaces errors without crashing the client.
• /krepapi menu: Client command to open the update / changelog screen at any time.
• KrepapiUpdateToast: One-time toast when an update is available; opens the menu (no direct download from the toast).
• KrepapiUpdateHud: Optional [KrepAPI ↑] indicator when an update is available; click opens the menu (no direct download from the HUD).

Fabric 1.21.x — MoulConfig update menu

• MoulConfig (modern-1.21.11) is bundled via GradleUp Shadow: dependency is relocated to net.shik.krepapi.deps.moulconfig, kotlin-stdlib is included for MoulConfig’s Kotlin internals, and a hand-authored META-INF/services/...IMinecraft entry points at the relocated platform class (Shadow does not rewrite service files by default).
• Access widener (krepapi.accesswidener): Merged the subset of MoulConfig widener entries that validate on Minecraft 1.21.11 with official Mojang mappings so the shaded UI can render without IllegalAccessError.
• Screen: KrepapiMenuScreen builds a MoulConfig GuiComponent tree (outer VANILLA panel, light header strip, full-width rule, two DARK_RECT columns). Left: “Changelogs” header, magenta underline, dashed separator, clickable version rows (cyan + underline when selected). Right: gray subtitle, scaled headline “Changelog entries for v…”, and formatted markdown body (yellow #, magenta ##, green ###, gray bullets; first top-level bullet after a ## section highlighted in white to match the reference layout).
• Headline scaling: Dynamic min(2×, fit-to-width) so long titles are not clipped inside the scroll viewport (fixes truncated v1. style glitches).
• ModMenu: modImplementation ModMenu 17.0.0-beta.2, dedicated KrepapiModMenuEntry → KrepapiModMenuIntegration config screen factory; fabric.mod.json extended with custom.modmenu (homepage, issues, GitHub link, update_checker).
• Helper UI types in net.shik.krepapi.client.ui.KrepapiMenuComponents: FullWidthRuleComponent, VersionNavRow, ChangelogHeadlineComponent, StatusBadgeComponent.

Fabric 26.1.x — Vanilla update menu

• KrepapiMenuScreen26: Same update semantics and markdown presentation using vanilla Screen widgets (no MoulConfig / Shadow on this loader).

Structured debug logging (optional)

• Paper (KrepapiPaperPlugin) and Fabric server networking: when debug-logging / JVM flag / marker file enables it, append NDJSON-style lines for handshake, disconnects, version kicks, and mouse/key events to a timestamped file under the server’s KrepAPI data folder.

Fixed

• Menu state: selectedVersion is only reset when missing from the remote versionList (or initially unset), so reopening the menu keeps the user’s chosen changelog version.
• Changelog headline: Avoids fixed 2× scale that exceeded the scroll clip and cut off the version suffix; headline now scales to the available width (up to 2×).
• Layout: Header row width accounts for panel insets so the top bar, rule, and body columns stay aligned at the designed inner width.

Changed

• fabric-1-21/build.gradle: GradleUp Shadow plugin, shadowModImpl / shadowImpl configurations, remapJar input from shadowJar; Maven Central for Kotlin; ModMenu and MoulConfig coordinates as used at build time.
• fabric.mod.json (1.21): contact, custom.modmenu, entrypoints.modmenu via KrepapiModMenuEntry; mixin / client resource layout adjusted (e.g. consolidated krepapi.mixins.json, removed redundant client mixin descriptor where applicable).
• fabric-26-1: Aligns fabric.mod.json, mixin config, and access widener with the split client/main setup used for the update UI.
• gradle.properties: mod_version set to 1.3.0 for this release line.
• Paper: Minor config.yml / KrepapiPaperVersionGate / KrepapiPaperPlugin tweaks for default minimum mod build alignment with the published mod.
• :protocol tests: KrepapiBuildVersionTest, KrepapiVersionPolicyTest, KrepapiVersionRequirementTest updated for current version policy behavior.
• Repository hygiene: .gitignore entries for editor-generated *Edit conflict* / *Name clash* duplicate source files.

Documentation

• Remote versions.json and changelog paths remain documented in-repo under .system/mod/ for the update checker URLs used by the client.
