Import march-2020-03-10 from private repo (scrubbed 2026-05-27)

Targets Rec Room 2020.03.10 client (also serves 2020.03.06).

Re-import after adding:
- DorkNet.ClientMod/dorknet-clientmod.json.template — config schema
  the launcher's manifest-driven patcher renders into UserData/.
- tools/build-patcher-zip.ps1 — produces dorknet-clientpatch-{key}.zip
  for v1-march-* Release uploads.
- .github/workflows/release.yml — on tag push publishes both
  dorknet-server-march_2020_03_10-win-x64.zip and
  dorknet-clientpatch-march_2020_03_10.zip as Release assets.

Same scrub rules as december; tools/build-patcher-zip.ps1 added to
the maintainer-side allow-list so it survives.

+# DorkNet — `march-2020-03-10`
+
+This is the **March 2020.03.10** branch of DorkNet — a self-hostable
+reimplementation of the Rec Room backend tuned to the wire protocol of
+the **Rec Room 2020.03.10** client build (also serves 2020.03.06).
+
+> ⚠️ **Not affiliated with Rec Room Inc. or Against Gravity.**
+> See [DISCLAIMER](../../blob/main/DISCLAIMER.md). DorkNet ships no Rec
+> Room game assets or modified binaries — you supply your own
+> legally-acquired Rec Room install.
+
+If you're not sure which DorkNet branch you want, start at the
+[main branch's chart](../../blob/main/BRANCHES.md). The launcher on
+main also auto-detects your install.

+
+## What this branch targets
+
+| | |
+|---|---|
+| **Client build** | Rec Room 2020.03.10 (also 2020.03.06) |
+| **Schema** | Multi-step EF migrations (~34 phases) |
+| **Diverges from `december-2020-12-18` by** | ~170 files |
+
+Subsystems **NOT** present on this branch (these landed in December):
+
+- Clubs surface
+- Playlists (curated + user-created)
+- Group DMs / chat threads
+- Weekly challenges
+- Room keys (purchasable room access)
+- Per-room co-owner / moderator / host roles
+- Late-2020 store catalog additions
+
+If you need any of those, you're on the wrong branch — see
+[`december-2020-12-18`](../../tree/december-2020-12-18).
+
+---
+
+## Quickstart
+
+**1. Install .NET 9 SDK** and (optionally) `dotnet-ef`:
+
+```pwsh
+dotnet tool install --global dotnet-ef
+```
+
+**2. Clone this branch:**
+
+```pwsh
+git clone --branch march-2020-03-10 https://github.com/DorkSquadRR/DorkNet
+cd DorkNet
+```
+
+**3. Configure secrets.** Drop in `DorkNet.Server/appsettings.Local.json`
+(gitignored) or export environment variables:
+
+| Config key | Env var | Required | Notes |
+|---|---|---|---|
+| `Jwt:Secret` | `Jwt__Secret` | yes | ≥64 random chars |
+| `Photon:AppId` | `Photon__AppId` | yes | Photon Realtime AppId (free at dashboard.photonengine.com) |
+| `Photon:VoiceAppId` | `Photon__VoiceAppId` | no | only if voice chat |
+| `Photon:CloudRegion` | `Photon__CloudRegion` | no | defaults to `us` |
+| `Database:Provider` | `Database__Provider` | no | `sqlite` (default) or `postgres` |
+| `ConnectionStrings:Default` | `ConnectionStrings__Default` | postgres-only | full Npgsql connection string |
+| `ConnectionStrings:Redis` | `ConnectionStrings__Redis` | no | enables SignalR backplane |
+| `Domain:Apex` | `DORKNET_DOMAIN` | no | defaults to `localhost`; set for production |
+
+**4. Boot:**
+
+```pwsh
+dotnet run --project DorkNet.Server
+```
+
+First boot creates `bin/Debug/net9.0/data/dorknet.db`, applies all EF
+migrations under `DorkNet.Server/Migrations/`, seeds canonical rooms +
+store catalog, and starts listening. You should see `Application
+started.` in the log; `curl http://localhost:8080/healthz` returns 200.
+
+For Docker / VPS, see [docs/deploy.md](docs/deploy.md).
+
+---
+
+## Patching your client
+
+```pwsh
+.\tools\install-plugin.ps1 `
+  -RecRoomPath "C:\Path\To\Recroom_Release_Data" `
+  -PhotonAppId "<your-photon-realtime-app-id>" `
+  -PhotonVoiceAppId "<your-photon-voice-app-id>"
+```
+
+This installs the BepInEx 6 plugin into the client's `BepInEx/plugins/`
+and writes its config under `BepInEx/config/`. The plugin rewrites all
+`*.rec.net` URIs to your configured DorkNet apex, swaps the Photon
+AppIds, and bypasses TLS verification on the client's HTTPS calls so
+self-signed certs work.
+
+If BepInEx isn't installable on the user's machine, the legacy
+`tools/install-legacy-client.ps1` does the same patches via direct
+byte-edits of `resources.assets` + `GameAssembly.dll`. Slower setup,
+no Harmony runtime needed.
+

+
+## Code map
+
+| Folder | Purpose |
+|---|---|
+| `DorkNet.Server/` | ASP.NET Core backend (controllers, services, data, hubs, middleware) |
+| `DorkNet.Server/Migrations/` | EF Core schema migrations applied at boot |
+| `DorkNet.Models/` | DTOs shared between server and client mod |
+| `DorkNet.ClientPatch/` | BepInEx IL2CPP plugin (production patcher) |
+| `DorkNet.ClientMod/` | MelonLoader port (alternative patcher) |
+| `tools/` | Installers + Cloudflare tunnel templates |
+
+Compared to `december-2020-12-18`, this branch's server is closer to
+the original 2020-Q1 wire shape — fewer endpoints, simpler entities,
+and the multi-step migrations haven't been consolidated.

+## Contributing
+
+See [main's CONTRIBUTING guide](../../blob/main/CONTRIBUTING.md) for
+the project-wide rules.
+
+Branch-specific:
+
+- Schema changes on this branch don't flow to `december-2020-12-18`
+  automatically. If a fix applies to both, cherry-pick it across.
+- Don't rebase across branches — they're independent forks.
+- New EF migrations: `dotnet ef migrations add <Name> --project DorkNet.Server`.
+  `Migrate()` runs on boot; don't run `database update` manually.
