+# Tessera
+
+Tessera is a clean desktop rendering host. It starts with an empty page. Coding agents submit source code to a namespace through a local CRUD API; Tessera parses that code, builds its architecture tree, compiles it to drawing commands, and renders the result.
+
+## Start
+
+```bash
+cargo run --release
+```
+
+Tessera listens only on `127.0.0.1:4737`.
+
+Start every agent integration by reading the live Markdown guide:
+
+```bash
+curl http://127.0.0.1:4737/agent
+```
+
+## Namespace code API
+
+The initial active namespace is `app.main`. Tessera has no file concept.
+
+```text
+GET    /v1/namespaces/app.main/code
+PUT    /v1/namespaces/app.main/code
+DELETE /v1/namespaces/app.main/code
+```
+
+Submit code as plain text:
+
+```bash
+curl \
+  --request PUT \
+  --header 'Content-Type: text/plain; charset=utf-8' \
+  --data-binary @- \
+  http://127.0.0.1:4737/v1/namespaces/app.main/code <<'TESSERA'
+namespace app.main
+
+use tessera.ui::{Column, Text}
+
+export scene Main {
+    render {

+Updates are atomic. Invalid code returns diagnostics with HTTP 422 and preserves the last successfully rendered revision.
+
+## Developer tools
+
+The developer sidebar is closed by default.
+
+- macOS: `Command-Option-I` or `F12`
+- Windows/Linux: `Control-Shift-I` or `F12`
+
+The upper section displays the compiler-produced architecture tree. Selecting a node shows the corresponding source range below it.
+
+## Current syntax experiment
+
+The first parser intentionally supports only enough syntax to test the architecture:
+
+- `namespace`
+- namespace-only `use`
+- one `export scene`
+- one `render` root
+- `Column`, `Row`, `Spacer`, and `Text`
+- `gap`, `padding`, and `.title`
+
+There are no files, HTML, CSS, JavaScript, DOM, or resource-network concepts in the runtime.

+
+Tessera stores code by namespace. It has no files. Submit code only; Tessera parses,
+checks, compiles, and renders it.
+
+## Code CRUD
+
+- Read: `GET http://{address}/v1/namespaces/{name}/code`
+- Create or update: `PUT http://{address}/v1/namespaces/{name}/code`
+- Delete: `DELETE http://{address}/v1/namespaces/{name}/code`
+
+Send PUT bodies as `text/plain; charset=utf-8`.
+
+## Minimal syntax
+
+```tessera
+namespace {name}
+
+use tessera.ui::{{Column, Row, Spacer, Text}}
+
+export scene Main {{
+    render {{
+        Column(gap: 12, padding: 24) {{
+            Text("Hello", role: .title)
+            Text("Rendered by Tessera")
+        }}
+    }}
+}}
+```
+
+Supported by this syntax experiment: one exported scene, one render root,
+`Column`, `Row`, `Spacer`, `Text`, `gap`, `padding`, and `.title`.
+Compilation errors reject the update and preserve the last rendered revision.
