+# Flathub submission
+
+These files publish CodeBurn Desktop on Flathub. The manifest repacks the
+Linux deb from GitHub Releases, so no source build is needed.
+
+## First-time submission
+
+1. Fork `https://github.com/flathub/flathub` (uncheck "fork only master").
+2. Create a branch off `new-pr` named `org.agentseal.CodeBurn`.
+3. Copy the three `org.agentseal.CodeBurn.*` files from this directory into the
+   repo root of that branch.
+4. Open a pull request against the `new-pr` branch of `flathub/flathub`.
+5. A reviewer responds on the PR. After approval Flathub creates a dedicated
+   `flathub/org.agentseal.CodeBurn` repo; future updates are PRs there.
+
+## Local test build (any Linux machine or VM)
+
+```sh
+flatpak install flathub org.flatpak.Builder
+flatpak run org.flatpak.Builder --force-clean --user --install \
+  --install-deps-from=flathub --repo=repo builddir org.agentseal.CodeBurn.yaml
+flatpak run org.agentseal.CodeBurn
+```
+
+## Each desktop release
+
+Update in `org.agentseal.CodeBurn.yaml`:
+- the deb `url` (new `desktop-vX.Y.Z` tag)
+- its `sha256` (`gh api repos/getagentseal/codeburn/releases/tags/desktop-vX.Y.Z -q '.assets[] | select(.name | endswith(".deb")) | .digest'`)
+
+and add a `<release>` entry in `org.agentseal.CodeBurn.metainfo.xml`.
+Then PR the `flathub/org.agentseal.CodeBurn` repo; merging publishes.

+    <p>
+      AI coding assistants have become a real cost, but the invoice is one line.
+      CodeBurn reads the session logs your AI coding tools already write on your
+      machine and turns them into itemized cost analytics: by project, model,
+      session, day, and pull request.
+    </p>
+    <p>
+      Everything runs locally. No API keys, no account, no data leaving your
+      machine.
