-Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+# ⚔️ Parry
+
+Duel a small language model that runs **entirely in your browser** (WebGPU), reads your
+patterns mid-match, **tells you what it learned about you**, and adapts — inside a
+sub-100ms reaction loop no cloud API can physically serve.
+
+- **Local-first:** the opponent's brain is a Qwen2.5-1.5B decoding one grammar-constrained
+  intent token every ~100ms on YOUR GPU. Pull your Wi-Fi out mid-match — nothing changes.
+- **Observable adaptation:** the Analyst's live read of you is rendered on screen, and the
+  debug panel lets you EDIT its read and watch the Tactician's play flip in real time.
+- **No WebGPU? You still play:** transparent server fallback (same model, same grammar)
+  served via Modal.
+
+Controls: ←/→ move · J strike · K feint · L parry · 1–5 switch opponent · Enter rematch.
+
+*(This Space is a `gradio.Server` app — Gradio's engine serves the custom canvas at `/`,
+and the Analyst endpoint runs through Gradio's queue, callable with `gradio_client`.)*
+
+NOTE deploy: copy the built client (`npm run build` → `dist/`) into `static/` before
+pushing; `app.py` serves `static/index.html` at `/`.

+PARRY — compliant Gradio hosting layer (C8) + server-side inference relay.
+
+Primary posture (per the verified research): `gradio.Server` (Gradio 6.x) on
+`sdk: gradio` — a FastAPI subclass running Gradio's engine, with our custom
+canvas served at GET / (custom routes take priority over the default UI; this
+is the official `ysharma/text-behind-image` pattern, and the custom-UI award
+text says "gr.Server is your friend").
+
+Defensive: if the pinned Gradio somehow lacks `Server`, we degrade to
+FastAPI + gr.mount_gradio_app so the Space still boots while we consult the
+hedge ladder (docker swap / gr.Blocks+gr.HTML — see ../space/app_blocks.py).
+
+Endpoints
+  GET  /            → static/index.html (the game)
+  GET  /static/*    → built Vite bundle (immutable assets)
+  POST /infer       → stateless Tactician relay → Modal vLLM {prompt, grammar_id, tier} → {token, t_ms}
+  POST /analyst     → stateless Analyst relay (raw fallback path)
+  api  "analyst"    → same, through Gradio's queue (compliance centerpiece; gradio_client-callable)
+  api  "about"      → build/model/grammar info via the queue
+  POST /funnel      → enum-validated JSONL beacons (+ optional CommitScheduler → private HF Dataset)
+  GET  /healthz     → {ok, modal, version, grammar_id}
+
+Secrets (Space settings): MODAL_INFER_URL, MODAL_INFER_KEY, HF_TOKEN (funnel dataset, optional),
+FUNNEL_DATASET (e.g. "user/parry-funnel", optional).
