Stage 5 of Deploy-Brass.ps1 was gated only on \$shouldRunLauncher, so a "-Stage Pack" run regenerated the manifest locally + mirrored pack/overrides/ to the share, but never copied the new manifest.json itself. Result: tweak jars/configs landed on the share, but clients fetching the (still-old) manifest never knew about the new SHA-1s and skipped the re-sync. Caught when fixing the brassandsigil_tweaks jar: the public manifest stayed at 0.9.2 even though local was 0.9.3. Split into two stages -- launcher exe stays gated on \$shouldRunLauncher, manifest.json now publishes whenever \$shouldRunPack (so any Pack, All, or Launcher deploy includes it).

.SYNOPSIS
|
|
One-shot deploy: build launcher + server, regenerate manifest, mirror the
|
|
deploy share, scp the server binary.
|
|
|
|
.DESCRIPTION
|
|
Reads `deploy.config.ps1` (sibling file, gitignored) for local paths +
|
|
SSH details. Stages run in order; -Stage limits which stages run.
|
|
|
|
The script does NOT auto-restart the production daemon. After a server
|
|
binary deploy it prompts you to do that yourself.
|
|
|
|
.PARAMETER Stage
|
|
All | Launcher | Server | Pack. Defaults to All.
|
|
|
|
Launcher = build launcher + regenerate manifest + push to deploy share
|
|
Server = build server + scp binary (atomic swap)
|
|
Pack = regenerate manifest + mirror pack/overrides/* to share
|
|
All = everything, in order
|
|
|
|
.PARAMETER SkipBuild
|
|
Skip dotnet publish steps. Use when you've already built and just want
|
|
to push artifacts.
|
|
|
|
.PARAMETER DryRun
|
|
Print each action without executing. No files copied, no SSH, no build.
