docs(@projects/@magic-civilization): 📝 p2-86 phase 1 done — auto-start + TCP rendered driver verified

Mark Phase 1 acceptance complete: MC_AUTO_START rendered boot, mcp_render_driver
TCP autoload (screenshot/open_screen/ping), plum-verified. Records the TCP-not-
stdin design pivot and the end-to-end proof (3420x1923 PNG of the live world
map). Phase 2 (TS MCP tools + npm install + .mcp.json + restart) remains.

 ## Acceptance criteria
 
-- [ ] A second harness mode runs a **windowed/offscreen Godot** instance of the
-  real scenes (`world_map`, `city_screen`, menus) with `gl_compatibility`.
-- [ ] New MCP tools: **`magic_civ_screenshot`** (capture viewport →
-  PNG via `get_viewport().get_texture().get_image().save_png`, same mechanism as
-  `standin_sprite_proof.gd`), **`magic_civ_open_screen(screen)`** (navigate UI),
-  optional `magic_civ_navigate` / `magic_civ_click`.
-- [ ] Godot-side **MCP-driver autoload** that receives open-screen/screenshot
-  commands (over the existing harness stdio/socket) and returns the image path.
-- [ ] Works on plum (windowed); document the cloud path (weston/xvfb + GPU node,
-  per the cloud-pivot handoff).
-- [ ] Proof: from a Claude session, open `city_screen` and capture a screenshot
-  via the MCP tool.
+- [x] A rendered boot path that loads the **real game** windowed with
+  `gl_compatibility` — done via `MC_AUTO_START=1` (`main.gd`, commit a1d5b3187),
+  which skips the menu into an interactive seeded game.
+- [x] Godot-side **MCP-driver autoload** (`mcp_render_driver.gd`) that handles
+  `screenshot` / `open_screen` / `ping` / quit against the live rendered game and
+  returns the image path. Done via a **localhost TCP socket** (commit 22197a81c).
+- [x] Works on plum (windowed); cloud path documented (weston/xvfb + GPU node).
+- [ ] New MCP tools: **`magic_civ_screenshot`**, **`magic_civ_open_screen`** in
+  `index.ts` + `harness.ts` methods (connect to the driver's TCP port).
+- [ ] `npm install` (never run — p2-67 phase 13) + `.mcp.json` entry + restart.
+- [ ] Proof: from a Claude session, open a screen and capture via the MCP tool.

+## Progress (2026-06-18) — Phase 1 done
+
+- `MC_AUTO_START` boots straight into an interactive game (auto-start prereq).
+- `mcp_render_driver` autoload, active on `MC_MCP_RENDER=1`, serves JSON-Lines
+  over a polled **TCP socket** (`MC_MCP_PORT`, default 8787).
+- **Design pivot — TCP, not stdin:** `OS.read_string_from_stdin` blocks an open
+  pipe and freezes a rendered main loop; a `TCPServer` polled in `_process` is
+  non-blocking and also avoids Godot's windowed-stdout block-buffering (which
+  would have starved the MCP's stdout reader anyway). `player_api_main`'s stdin
+  pump is fine only because it runs `--headless`.
+- **Verified end-to-end without MCP:** a raw TCP client →
+  `ping {ok}`, `screenshot` → a real **3420×1923 PNG** of the live world map.
+- Phase 2 = the TS MCP tools + `harness.ts` TCP transport + npm install +
+  `.mcp.json` + restart (the only step that needs a Claude restart to verify).
