REM IridescentCraft Server - Unified Installer + Launcher (Windows)
REM Forge 1.20.1-47.4.6 with 420+ mods
REM
REM First run:  Installs Forge, downloads mods, then starts the server
REM Later runs: Skips install (mods already present), starts the server
REM
REM Requirements:
REM   - Java 17 (e.g., Adoptium/Temurin JDK 17)
REM   - RAM: 12 GB base + ~2 GB per concurrent player
REM     (16 GB for 2 testers; 22 GB for 5; 14 GB single-tester floor)
REM
REM Service mode (set ICRAFT_SERVICE_MODE=1 in env):
REM   - Skips Phase 0 GitHub sync (Z: mirror is authoritative)
REM   - Skips all `pause` calls so the bat can exit cleanly under NSSM
REM   - Recommended when launched via Windows service (e.g., NSSM IridescentMC)

title IridescentCraft Server

REM One-click bootstrap: when the bat is run from a folder that doesn't
REM contain the install marker (.icraft_server), set up a clean subfolder
REM `IridescentCraft Dedicated Server\`, copy the bat there, and relaunch
REM from there. Marker check is on the *current* folder so the relaunched
REM instance (which lives inside the subfolder, with marker present) falls
REM through to the rest of the script instead of creating a nested folder.
REM
REM Single source of truth: .icraft_server. Earlier versions had a separate
REM "system folder detection" branch (Downloads/Desktop/etc.) with its check
REM pointed at the nested subfolder's marker, which caused infinite folder
REM nesting when the relaunched instance still saw \Downloads\ in its path.

REM Phase -1: Z:-mounted dev-PC mirror (preferred when reachable)
REM -------------------------------------------------------------------
REM sync_from_repo.bat copies the whole server_distribution/ tree from
REM Z: (dev PC's repo working tree). When Z: is mounted this is
REM faster + more reliable than phase0_sync's GitHub diff-API:
REM   - no GitHub API rate limits
REM   - no truncated-diff edge cases (>=300 changed files -> full zip)
REM   - sees uncommitted local edits the dev PC has on the working tree
REM Falls back internally to a GitHub zip download if Z: isn't mounted.
REM
REM Service mode skips Phase -1 entirely:
REM   - Z: is per-user-session, not visible to LocalSystem service ->
REM     sync would always fall through to slow GitHub download
REM   - GitHub download takes 5-15 min per restart (hundreds of MB)
REM   - Service-mode deployed state IS authoritative; no need to pull
REM     from anywhere on service start. Dev-box pushes go through the
REM     interactive bat invocation OR a manual restart after editing.

REM Phase 0: Self-Update from GitHub (diff-based)
REM -------------------------------------------------------------------
REM Uses phase0_sync.ps1 for diff-based updates: compares commit SHAs,
REM then downloads ONLY the changed files via GitHub compare API +
REM raw.githubusercontent.com. Typical sync: 5-10 seconds for 3-10 files.
REM Falls back to full zip download on first run or when >=300 files changed.
REM
REM If phase0_sync.ps1 doesn't exist yet (first ever deploy), download it
REM from raw.githubusercontent.com before calling it.

REM -Force flag: delete the SHA marker to trigger a full re-sync. Use this
REM when the server state doesn't match the repo despite the marker saying
REM "up to date" (e.g., after a diff-sync missed files silently).
if /i "%1"=="-Force"     set "FORCE_SYNC=1"

REM Service mode skips Phase 0 GitHub sync. Two reasons:
REM   1. Avoids the auto-overwrite footgun where the GitHub state reverts
REM      local server-side edits that haven't been pushed yet.
REM   2. Phase 0's HTTP downloads + child PowerShell hung indefinitely under
REM      non-foreground scheduled-task execution. Skipping bypasses both.
REM Z: sync (Phase -1) above is authoritative in service mode.
