+# Dotcom Arcade: notes for agents
+
+Dotcom Arcade is a heavily modified fork of
+[flashpoint-web](https://github.com/darkraise/flashpoint-web) by darkraise
+(GPL-3.0), with game streaming added under `streaming/`. Coding standards and
+architecture notes are in `CLAUDE.md`; feature and deployment docs are in
+`docs/`.
+
+## Upstream
+
+- **Upstream** is https://github.com/darkraise/flashpoint-web, branch `master`.
+  It's read-only from here: don't push to it or open pull requests there unless
+  asked.
+- **Most of upstream's code is still used:** the backend, the frontend's data
+  layer, the player, and the account and admin pages. Fixes to these should come
+  in from upstream rather than being rewritten here.
+- **To see what upstream has changed** since it was last merged, and how each
+  touched file stands here, run `scripts/upstream-status.sh`.
+- **To pull changes in**, follow `docs/08-development/upstream-sync.md`. In
+  short:
+  - merge upstream's `master` on a branch (don't cherry-pick);
+  - keep files removed here removed;
+  - keep the Dotcom Arcade branding;
+  - keep upstream's migration file names;
+  - have the pull request merged with a merge commit, never squashed, so the
+    next sync starts from the right place.
+- **Parts that are only ours:**
+  - `streaming/`;
+  - `scripts/`;
+  - `frontend/src/components/portal/`;
+  - `views/GamePage.tsx`;
+  - `lib/saves/flashSaves.ts`;
+  - the discovery backend;
+  - `.gitea/`;
+  - migrations upstream doesn't have.
+
+## GitHub mirror
+
+`mirror/` publishes `main` to a read-only GitHub mirror from the operator's
+host, never from a session; see `docs/08-development/github-mirror.md`. GitHub
+runs `.github/workflows`, the forge `.gitea/workflows`; keep the two image
+workflows in step.
+
+## CI
+
+Workflows are in `.gitea/workflows`. Jobs that run docker builds use the
+`dejima-privileged` runner label; anything else uses `dejima-confined`. The
+privileged job image has no Docker client, so install `docker-ce-cli` first.
+Never hardcode the forge's host name: read it at run time, or take it from the
+`REGISTRY_HOST` repository variable.

+# GitHub mirror
+
+Dotcom Arcade is developed on a private forge. `mirror/github-mirror.sh`
+publishes its `main` and the tags on `main` to
+[github.com/branderson/dotcom-arcade](https://github.com/branderson/dotcom-arcade),
+hourly, from a host that can push to GitHub. Issues and pull requests are off
+there. Actions stays on, since it builds the images that `ghcr.io/branderson/`
+serves (see [publishing images](../09-deployment/docker-deployment.md#publishing-images)).
+
+The mirror's `main` is the forge's plus one commit, which adds a read-only notice
+under the README's title. Every forge commit is in the mirror unchanged, and
+each sync fast-forwards. If the README loses its `# ` title, the sync stops
+instead of publishing without the notice.
+
+## Setup
+
+1. Set up the timer as described at the top of
+   `mirror/dotcom-arcade-github-mirror.service`. Give it a deploy key with write
+   access to the GitHub repository.
+2. Run `github-mirror.sh --dry-run` to build what a sync would publish without
+   pushing it.
+3. Once the first sync has pushed, run `github-mirror.sh --settings` (needs
+   `gh`). It turns off issues, pull requests, projects, wiki and discussions.
+4. The first image build creates its packages as private. In each package's
+   settings on GitHub, set its visibility to public.
+
+The timer runs a copy of the script, not the checkout's. Reinstall it after
+reviewing a change to `mirror/`.

+# Syncing with upstream flashpoint-web
+
+Dotcom Arcade is a heavily modified fork of
+[flashpoint-web](https://github.com/darkraise/flashpoint-web) by darkraise
+(branch `master`). Most of upstream's code is still used here: the backend, the
+frontend's data layer, the player, and the account and admin pages. Upstream's
+fixes and features to those parts should keep coming in, so the two projects
+don't drift apart.
+
+## What's whose
+
+Comparing this repository with the last upstream commit merged into it:
+
+- **Unchanged here:** most of the backend, the API client, hooks, stores and
+  types, the player, the account and admin views, and most docs. Upstream
+  changes to these merge as they are.
+- **Changed here:** files upstream also owns that this project has modified.
+  The main ones:
+  - `GameService` (mature filter, release ranges, shuffle, related games);
+  - `server.ts` and `config.ts` (stream proxy, update check);
+  - `App.tsx` (portal routes);
+  - `GamePlayer` (streaming, saves);
+  - the browse layout and filters;
+  - the rebrand across names and docs.
+
+  Upstream changes to these need merging by hand.
+- **Removed here:**
+  - the Flash and HTML5 sections;
+  - the GitHub stars endpoint;
+  - the old homepage pieces;
+  - the dev compose file;
+  - upstream's CI workflow and design notes.
+
+  These stay removed.
+- **Only here:**
+  - `streaming/`;
+  - `scripts/`;
+  - `frontend/src/components/portal/`;
+  - `views/GamePage.tsx`;
+  - `lib/saves/flashSaves.ts`;
+  - `.gitea/`;
+  - the discovery backend;
+  - migrations upstream doesn't have.
+
+  Upstream never touches these, but a change elsewhere can still need matching
+  work here.
+
+`scripts/upstream-status.sh` lists upstream's new commits and puts every file
+they touch in one of these groups, so this list doesn't need keeping up to date
+by hand.
+
+## When
+
+Run `scripts/upstream-status.sh` when upstream publishes a release, and at
+least monthly. Sync when it shows new commits.
+
+## How
+
+1. On a branch from `main`, merge upstream:
+
+   ```sh
+   scripts/upstream-status.sh
+   git checkout -b upstream-sync-$(date +%Y-%m-%d) origin/main
+   git merge refs/remotes/upstream/master
+   ```
+
+2. Resolve conflicts by group:
+   - **Changed here:** keep this project's behavior and take upstream's fix or
+     feature with it. Where they truly conflict, prefer this project's
+     behavior, and note what was left out in the pull request.
+   - **Removed here:** keep the file deleted
+     (`git rm <file>`). If upstream's change matters elsewhere, such as a bug
+     fix in shared logic, port that part to where the code lives now.
+   - **New upstream:** take it, unless it belongs to something removed here.
+     New UI usually lands in the old application layout. Decide whether it
+     belongs in the portal, and if so, follow up with a portal version.
+   - **Branding:** keep "Dotcom Arcade", our image and container names, and our
+     update check (`APP_UPDATE_URL`); don't take back upstream's.
+3. Migrations: keep upstream's migration files under their own names, even
+   when a number clashes with ours. The migrations table records full names,
+   so `009_app_tagline` and an upstream `009_something` both run, in name
+   order. Renaming an upstream migration would run it a second time on
+   databases that already applied it. Check that ours and theirs don't depend
+   on each other's order.
+4. Check the result:
+   - backend and frontend typecheck, tests and build;
+   - the session manager's tests if `streaming/` was affected;
+   - `docker compose up -d --build` with and without the `streaming` profile;
+   - the docs, for anything the merge made inaccurate.
+5. Open a pull request listing upstream's commits and how each conflict was
+   resolved. **Merge it with a merge commit, not squash or rebase.** The merge
+   records how far upstream has been synced, so the next run of
+   `scripts/upstream-status.sh` starts from the right place.
+
+## Sending changes upstream
+
+Fixes made here to code upstream still shares, such as backend bugs, may be
+worth offering upstream. Do that separately, from a branch based on upstream's
+`master`, and only when the project's maintainer decides to.

+## Ruffle and the original Flash Player
+
+A Flash game's saves carry over when switching between Ruffle and the original
+Flash Player (streamed). Both store SharedObjects in the same `.sol` format,
+under different names:
+
+- Ruffle keeps them in localStorage, keyed by the site's host and the path it
+  loaded the SWF from.
+- Flash Player keeps them as files under `Flash_Player/#SharedObjects/` in the
+  streamed game's saves, keyed by the SWF's own host and path.
+
+Starting the original Flash Player adds the game's Ruffle saves to the files the
+stream starts with. While it plays, its saves are copied back into Ruffle's
+storage as they change. Saves made with a `localPath` of `/` are shared by
+every game in Ruffle, so only those seen changing while this game ran are
+carried over.
+
+Ruffle's copy of a save is kept up to date in both directions, so it's the one
+the stream starts with:
+
+- Before Ruffle starts a game, it's given any of the stream's saves it doesn't
+  have yet, such as progress made only in the stream. The game then loads that
+  progress instead of starting a fresh save, which would otherwise replace the
+  stream's progress on the next switch. Saves Ruffle already has are left alone.
+- While the stream plays, the saves it changes are copied into Ruffle.
+
+Some games save under a different path in each player. A SWF that a wrapper
+(such as MochiAds) loads from memory saves under its loader's path plus
+`[[DYNAMIC]]/<n>`, and a wrapper may do that in Ruffle but not in the
+standalone Flash Player. Bloons, for example, keeps its progress under
+`bloons.swf/[[DYNAMIC]]/1/` in Ruffle and under `bloons.swf/` in Flash Player.
+Saves that differ only by that step are treated as one save:
+
+- When the stream starts, a save is written to every path the stream has for
+  it. If Ruffle has both a dynamic and a plain copy, the dynamic one is used.
+- A save the stream changes is copied to every key Ruffle has for it.
+
+A stream save replaced this way is still in the account's backups.

 ## Sync
 
 Before a game starts, the app compares the browser's save with the account's
