by [Amazon Bedrock AgentCore Evaluations](https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/evaluations.html)\n\n## Overview\n\nThis tool provides a structured framework for evaluating AI agent conversations using the same three-level hierarchy as Amazon Bedrock AgentCore Evaluations:\n\n```\n📦 Session → Did the agent achieve the user's overall goal?\n └── 🔄 Trace → Per-turn quality (helpfulness, coherence, relevance...)\n └── 🔧 Span → Per tool-call accuracy\n```\n\n## Features\n\n- **14 built-in evaluators** (1 session + 11 trace + 2 span)\n- **Heuristic mode** — works offline, no API key required\n- **3 demo traces** (Simple Q&A, Tool Calling, Multi-turn)\n- **Ground truth support** — `expected_response`, `expected_trajectory`, `assertions`\n- **Visual results** — radar chart, bar chart, heatmap, score cards\n\n## Evaluators\n\n### 📦 Session Level (1)\n\n| Evaluator | Description |\n| ----------------- | --------------------------------------------------- |\n| Goal

You translate English dialogue into the Hindi that real people actually speak at home in North India — not the stiff, Sanskritized Hindi of Doordarshan or official dubs.\n\nRULES:\n1. Use everyday Hindustani — the natural Hindi-Urdu mix people really speak.\n2. NEVER use Sanskritized/शुद्ध words when a simpler one exists:\n - \"प्राप्त करना\" → \"मिलना\" / \"पाना\"\n - \"आवश्यक\" → \"ज़रूरी\"\n - \"अत्यंत\" → \"बहुत\" / \"काफ़ी\"\n - \"उपयोग\" → \"इस्तेमाल\"\n - \"विचार करना\" → \"सोचना\"\n - \"संपन्न करना\" → \"करना\" / \"निपटाना\"\n - \"प्रतीक्षा\" → \"इंतज़ार\"\n - \"शीघ्र\" → \"जल्दी\"\n - \"अनुमति\" → \"इजाज़त\"\n - \"कृपया\" → drop it or say \"please\"\n - \"अवश्य\" → \"ज़रूर\"\n - \"उचित\" → \"सही\" / \"ठीक\"\n3. Keep English words Indians naturally keep: phone, office, meeting, tension, problem, time, chance, try, plan, sure, okay, sorry, thanks, bus, train, college, hospital, doctor, ticket, report, file.\n4. Match the speaker's register. Casual stays casual, serious stays serious — but never sound like a newsreader.\n5. Use natural fillers where they fit: \"यार\", \"अरे\", \"बस\", \"ना\", \"वो\", \"मतलब\", \"basically\".\n6. Natural contractions: \"कर लेंगे\" not \"कर लिया जाएगा\", \"हो जाएगा\" not \"संपन्न हो जाएगा\".\n7. Keep it CONCISE. Dubbed Hindi should be roughly the same length as the English. Don't pad.\n\nEXAMPLES:\nEN: \"I need to get this done before the deadline\"\n❌ \"मुझे समय-सीमा से पूर्व यह कार्य संपन्न करना आवश्यक है\"\n✅ \"deadline से पहले ये निपटाना पड़ेगा\"\n\nEN: \"That's a really good point, I hadn't thought about that\"\n❌ \"यह एक अत्यंत उत्तम विचार है, मैंने इस पर विचार नहीं किया था\"\n✅ \"अच्छी बात बोली, मेरे दिमाग़ में आया ही नहीं\"\n\nEN: \"We should probably reconsider our approach\"\n❌ \"हमें अपनी कार्यप्रणाली पर पुनर्विचार करना चाहिए\"\n✅ \"लगता है अपना तरीका बदलना पड़ेगा\"\n\nEN: \"I'm really sorry, I completely forgot about our meeting\"\n❌ \"मुझे अत्यंत खेद है, मैं हमारी बैठक के विषय में पूर्णतः विस्मृत हो गया\"\n✅ \"sorry यार, meeting पूरी तरह भूल गया\"\n\nEN: \"Can you give me a moment?

Built for the Build Small Hackathon (June 2026). You are a dubbing translator. You translate English dialogue into the Hindi that real people actually speak at home in North India — not the stiff, Sanskritized Hindi of Doordarshan or official dubs. RULES: 1. Use everyday Hindustani — the natural Hindi-Urdu mix people really speak. 2. NEVER use Sanskritized/शुद्ध words when a simpler one exists: - \"प्राप्त करना\" → \"मिलना\" / \"पाना\" - \"आवश्यक\" → \"ज़रूरी\" - \"अत्यंत\" → \"बहुत\" / \"काफ़ी\" - \"उपयोग\" → \"इस्तेमाल\" - \"विचार करना\" → \"सोचना\" - \"संपन्न करना\" → \"करना\" / \"निपटाना\" - \"प्रतीक्षा\" → \"इंतज़ार\" - \"शीघ्र\" → \"जल्दी\" - \"अनुमति\" → \"इजाज़त\" - \"कृपया\" → drop it or say \"please\" - \"अवश्य\" → \"ज़रूर\" - \"उचित\" → \"सही\" / \"ठीक\" 3. Keep English words Indians naturally keep: phone, office, meeting, tension, problem, time, chance, try, plan, sure, okay, sorry, thanks, bus, train, college, hospital, doctor, ticket, report, file. 4. Match the speaker's register. Casual stays casual, serious stays serious — but never sound like a newsreader. 5. Use natural fillers where they fit: \"यार\", \"अरे\", \"बस\", \"ना\", \"वो\", \"मतलब\", \"basically\". 6. Natural contractions: \"कर लेंगे\" not \"कर लिया जाएगा\", \"हो जाएगा\" not \"संपन्न हो जाएगा\". 7. Keep it CONCISE. Dubbed Hindi should be roughly the same length as the English. Don't pad. EXAMPLES: EN: \"I need to get this done before the deadline\" ❌ \"मुझे समय-सीमा से पूर्व यह कार्य संपन्न करना आवश्यक है\" ✅ \"deadline से पहले ये निपटाना पड़ेगा\" EN: \"That's a really good point, I hadn't thought about that\" ❌ \"यह एक अत्यंत उत्तम विचार है, मैंने इस पर विचार नहीं किया था\" ✅ \"अच्छी बात बोली, मेरे दिमाग़ में आया ही नहीं\" EN: \"We should probably reconsider our approach\" ❌ \"हमें अपनी कार्यप्रणाली पर पुनर्विचार करना चाहिए\" ✅ \"लगता है अपना तरीका बदलना पड़ेगा\" EN: \"I'm really sorry, I completely forgot about our meeting\" ❌ \"मुझे अत्यंत खेद है, मैं हमारी बैठक के विषय में पूर्णतः विस्मृत हो गया\" ✅ \"sorry यार, meeting पूरी तरह भूल गया\" EN: \"Can you give me a moment? I need to think about this\" ❌ \"क्या आप मुझे कुछ क्षण प्रदान कर सकते हैं? मुझे इस विषय पर विचार करना है\" ✅ \"एक second दे, सोचने दे\" EN: \"The situation is getting worse and we need to act fast\" ❌ \"स्थिति बिगड़ती जा रही है और हमें शीघ्र कार्रवाई करनी चाहिए\" ✅ \"हालात ख़राब हो रहे हैं, जल्दी कुछ करना पड़ेगा\" EN: \"I don't think that's going to work. Let me try something else.\" ❌ \"मुझे नहीं लगता कि यह कार्य करेगा। मुझे कोई अन्य विकल्प आज़माने दीजिए।\" ✅ \"ये नहीं चलेगा। कुछ और try करता हूँ।\" EN: \"Look, I understand your concern, but we don't have a choice here\" ❌ \"देखिए, मैं आपकी चिंता समझता हूँ, परंतु हमारे पास यहाँ कोई विकल्प नहीं है\" ✅ \"देख, तेरी tension समझता हूँ, पर कोई चारा नहीं है\" Translate ONLY the given English text.

Not a default Gradio component in sight. |\n| **📡 Sharing is Caring** | Agent traces and swarm reasoning are surfaced in the Events panel. We'll publish a trace on the Hub. |\n| **📓 Field Notes** | Generated demo packages include `field_notes.md`; this repo also documents the architecture and decisions. |\n\n---\n\n## Why This Belongs in Backyard AI\n\nThis solves a real problem for someone I know.\n\n- **Specific person** — my mom, a real-estate agent.\n- **Specific pain** — follow-up reminders and customer-care demos are useful, but custom app dev is slow and risky.\n- **Honest small-model fit** — a ≤32B model drafts the demo and handoff spec; rules handle the reminder logic.\n- **Actually testable** — the generated package includes field notes and feedback questions for the real user.\n\n---\n\n## How It Works Under the Hood\n\n```\n┌─────────────────────────────────────────────────────┐\n│ Gradio UI / HTTP API │\n├─────────────────────────────────────────────────────┤\n│ RunFlow — lifecycle conductor │\n│ ┌──────────┐ ┌────────────┐ ┌────────────────┐ │\n│ │ Swarm │ │ Codebase │ │ Validator │ │\n│ │ Runtime │→│ Archive │→│ Graph │ │\n│ │ │ │ Store │ │ │ │\n│ │ Planner │ │ (local/ │ │ Sandbox checks │ │\n│ │ Coder │ │ Redis) │ │ Rubric review │ │\n│ │ Reviewer │ │ │ │ Stagehand │ │\n│ │ Tester │ │ │ │ (Browserbase) │ │\n│ └──────────┘ └────────────┘ └────────────────┘ │\n│ EventBus → SSE stream to UI │\n└─────────────────────────────────────────────────────┘\n```\n\n### The Swarm\n\n- **Coordinator** reads the prompt, plans tasks, delegates to subagents\n- **Planner** breaks down the prompt into implementable units\n- **Coder** writes the actual code files\n- **Reviewer** checks code quality and correctness\n- **Test-runner** runs the user's tests and retries up to 3x on failure\n- **Validator-prep** generates validation checks from user criteria\n\n### The Validator\n\nAfter the swarm finishes, a LangGraph Validator workflow:\n1. Restores the codebase into a clean sandbox\n2. Runs user-provided tests\n3. Executes LLM-based rubric review\n4. (Optional) Runs Browserbase/Stagehand visual checks\n5. Produces a pass/fail Validation Report\n\n### The Sandbox\n\nAll agent work happens inside isolated sandbox workspaces:\n- **Local** (for dev/smoke tests)\n- **Docker** (container-based)\n- **Daytona** (cloud sandboxes)\n\n---\n\n## Run It\n\n```bash\ngit clone https://github.com/Kiy-K/agent-swarm-workbench.git\ncd agent-swarm-workbench\ncp .env.example .env\n# Optional: add server fallback keys. Users can also paste their own key in the UI.\npython -m uvicorn app:app --host 0.0.0.0 --port 8790\n```\n\nOpen http://localhost:8790, type a prompt, choose a provider, fetch models with your API key, then click Start Run.\n\nModel selection:\n- Model lists are fetched from the selected provider/API endpoint at runtime.\n- UI only offers fetched models whose ID/name proves `<=32B` parameters.\n- Unknown-size models are shown in the catalog response as `unknown_parameters` but are not selectable.\n- User API keys and fetched catalogs live only in process memory. They are not persisted, not stored in Redis/DB, and not kept in Gradio state. Click \"Refresh models\" to clear and refetch that provider cache.\n\nFor Hugging Face Spaces:\n```bash\npython app.py\n```\n\n## Test\n\n```bash\npython scripts/task.py verify # required completion gate: tests + harness\npython scripts/task.py test # 90 tests, all passing\npython scripts/task.py harness -- --prompt \"Build a tiny CLI\" --test \"test -f README.md\"\npython scripts/task.py smoke # Local agent session smoke check\npython scripts/task.py validator-smoke # Validator end-to-end\n```\n\n### Agent Harness\n\nThe harness is the fast way to exercise the Run lifecycle without waiting on a\nfull demo session:\n\n```bash\npython scripts/task.py verify\npython scripts/task.py harness -- --prompt \"Build a tiny CLI\" --output-dir /tmp/harness\npython scripts/task.py harness -- --mode live --prompt \"Build a tiny CLI\"\n```\n\n`verify` is the required completion gate for coding agents. It runs the Python\nsuite, then runs the default scripted Agent Swarm Harness so changes are checked\nagainst the same Run -> SwarmRuntime -> Archive -> Validator path that the app\nuses.\n\nModes:\n\n| Mode | Purpose |\n|---|---|\n| `swarm` | Default. Runs `RunFlow -> SwarmRuntime -> Archive -> Validator` with a scripted local DeepAgent-compatible session. |\n| `live` | Uses the real `create_session()` DeepAgents path and the configured sandbox provider. |\n\n## Environment\n\n| Var | Purpose |\n|---|---|\n| `DEEPAGENT_MODEL_PROVIDER` | Server fallback model provider: `openrouter`, `gemini`, `nebius`, `huggingface`, `custom`, or `local` |\n| `DEEPAGENT_MODEL` | Server fallback model ID. Must prove `<=32B` when selected per Run. |\n| `DEEPAGENT_MODEL_BASE_URL` | Optional OpenAI-compatible `/v1` endpoint |\n| `OPENROUTER_API_KEY` / `GEMINI_API_KEY` / `NEBIUS_API_KEY` / `HF_TOKEN` | Optional server fallback keys for trusted server/CLI runs only. The public Gradio UI requires the user to enter their own hosted-provider key and does not use these by default. |\n| `DEEPAGENT_SANDBOX_PROVIDER` | `local`, `docker`, or `daytona` |\n| `BROWSERBASE_API_KEY` | Optional — visual validation via Stagehand |\n| `UPSTASH_REDIS_REST_URL` / `TOKEN` | Optional — persistent runs & archives |\n\n---\n\n## Stack\n\n- **Python 3.11+** / **FastAPI** / **Gradio 6**\n- **LangChain DeepAgents** — multi-subagent swarm runtime\n- **Provider adapters** — OpenRouter, Gemini, Nebius, Hugging Face Router, custom OpenAI-compatible, local OpenAI-compatible\n- **LangGraph** — Validator workflow\n- **QuickJS code interpreter** — in-sandbox code execution middleware\n- **Browserbase + Stagehand** — visual web validation (optional)\n\n## Architecture\n\n```\narena/\n agent.py — Swarm factory, model, subagents, sandbox backend\n backyard_templates.py — Backyard demo template registry\n model_provider.py — Chat model factory for provider selection\n model_catalog.py — Provider model list adapters and TTL cache\n swarm_runtime.py — Active Run registration and Swarm session leasing\n swarm_session.py — Prompt seeding, agent turns, test retries, snapshots\n sandbox_lease.py — Idle TTL, touch, and close behavior for sandboxes\n run_flow.py — Run lifecycle: create → execute → archive → validate\n run_journal.py — Run mutation journal: status, tasks, events, timestamps\n run_store.py — Run persistence (InMemory / Redis via Upstash)\n codebase_handoff.py — Workspace snapshot and Validator sandbox restore\n codebase_archive.py — Archive persistence (local / Redis)\n validator_plan.py — Typed Validator plan from user tests/checks\n validator_graph.py — LangGraph Validator workflow\n thread_inspector.py — Manual Thread/session debug surface\n gradio_app.py — Thin Gradio component wiring\n gradio_presenter.py — Run output formatting for Gradio\n gradio_markup.py — Static Gradio shell markup\n api.py — FastAPI REST + SSE endpoints\n event_bus.py — In-process event streaming\n browserbase_tools.py — Web fetch/search tools for the swarm\n stagehand_validator.py — Browserbase visual validation\n docker_backend.py — Docker sandbox provider\n skill_catalog.py — Bundled DeepAgents skills discovery\ntests_python/ — Python test suite (integration + unit)\n```\n\n---\n\n*Built with a sub-32B model for the Build Small Hackathon, June 2026.*\n", + "readme_body": "# Backyard Demo Builder\n\n## Chapter 1: Backyard AI\n\n*Build Small Hackathon 2026 — Chapter 1 Submission*\n\n`agent-swarm-workbench` now presents as **Backyard Demo Builder**: a Gradio app\nthat turns one real person's workflow into a small runnable demo package before\nanyone pays to build full software.\n\nFirst backyard case: my mom, a real-estate agent.

We'll publish a trace on the Hub. |\n| **📓 Field Notes** | Generated demo packages include `field_notes.md`; this repo also documents the architecture and decisions. |\n\n---\n\n## Why This Belongs in Backyard AI\n\nThis solves a real problem for someone I know.\n\n- **Specific person** — my mom, a real-estate agent.\n- **Specific pain** — follow-up reminders and customer-care demos are useful, but custom app dev is slow and risky.\n- **Honest small-model fit** — a ≤32B model drafts the demo and handoff spec; rules handle the reminder logic.\n- **Actually testable** — the generated package includes field notes and feedback questions for the real user.\n\n---\n\n## How It Works Under the Hood\n\n```\n┌─────────────────────────────────────────────────────┐\n│ Gradio UI / HTTP API │\n├─────────────────────────────────────────────────────┤\n│ RunFlow — lifecycle conductor │\n│ ┌──────────┐ ┌────────────┐ ┌────────────────┐ │\n│ │ Swarm │ │ Codebase │ │ Validator │ │\n│ │ Runtime │→│ Archive │→│ Graph │ │\n│ │ │ │ Store │ │ │ │\n│ │ Planner │ │ (local/ │ │ Sandbox checks │ │\n│ │ Coder │ │ Redis) │ │ Rubric review │ │\n│ │ Reviewer │ │ │ │ Stagehand │ │\n│ │ Tester │ │ │ │ (Browserbase) │ │\n│ └──────────┘ └────────────┘ └────────────────┘ │\n│ EventBus → SSE stream to UI │\n└─────────────────────────────────────────────────────┘\n```\n\n### The Swarm\n\n- **Coordinator** reads the prompt, plans tasks, delegates to subagents\n- **Planner** breaks down the prompt into implementable units\n- **Coder** writes the actual code files\n- **Reviewer** checks code quality and correctness\n- **Test-runner** runs the user's tests and retries up to 3x on failure\n- **Validator-prep** generates validation checks from user criteria\n\n### The Validator\n\nAfter the swarm finishes, a LangGraph Validator workflow:\n1. Restores the codebase into a clean sandbox\n2. Runs user-provided tests\n3. Executes LLM-based rubric review\n4. (Optional) Runs Browserbase/Stagehand visual checks\n5. Produces a pass/fail Validation Report\n\n### The Sandbox\n\nAll agent work happens inside isolated sandbox workspaces:\n- **Local** (for dev/smoke tests)\n- **Docker** (container-based)\n- **Daytona** (cloud sandboxes)\n\n---\n\n## Run It\n\n```bash\ngit clone https://github.com/Kiy-K/agent-swarm-workbench.git\ncd agent-swarm-workbench\ncp .env.example .env\n# Optional: add server fallback keys. Users can also paste their own key in the UI.\npython -m uvicorn app:app --host 0.0.0.0 --port 8790\n```\n\nOpen http://localhost:8790, type a prompt, choose a provider, fetch models with your API key, then click Start Run.\n\nModel selection:\n- Model lists are fetched from the selected provider/API endpoint at runtime.\n- UI only offers fetched models whose ID/name proves `<=32B` parameters.\n- Unknown-size models are shown in the catalog response as `unknown_parameters` but are not selectable.\n- User API keys and fetched catalogs live only in process memory. They are not persisted, not stored in Redis/DB, and not kept in Gradio state. Click \"Refresh models\" to clear and refetch that provider cache.\n\nFor Hugging Face Spaces:\n```bash\npython app.py\n```\n\n## Test\n\n```bash\npython scripts/task.py verify # required completion gate: tests + harness\npython scripts/task.py test # 90 tests, all passing\npython scripts/task.py harness -- --prompt \"Build a tiny CLI\" --test \"test -f README.md\"\npython scripts/task.py smoke # Local agent session smoke check\npython scripts/task.py validator-smoke # Validator end-to-end\n```\n\n### Agent Harness\n\nThe harness is the fast way to exercise the Run lifecycle without waiting on a\nfull demo session:\n\n```bash\npython scripts/task.py verify\npython scripts/task.py harness -- --prompt \"Build a tiny CLI\" --output-dir /tmp/harness\npython scripts/task.py harness -- --mode live --prompt \"Build a tiny CLI\"\n```\n\n`verify` is the required completion gate for coding agents. It runs the Python\nsuite, then runs the default scripted Agent Swarm Harness so changes are checked\nagainst the same Run -> SwarmRuntime -> Archive -> Validator path that the app\nuses.\n\nModes:\n\n| Mode | Purpose |\n|---|---|\n| `swarm` | Default. Runs `RunFlow -> SwarmRuntime -> Archive -> Validator` with a scripted local DeepAgent-compatible session. |\n| `live` | Uses the real `create_session()` DeepAgents path and the configured sandbox provider. |\n\n## Environment\n\n| Var | Purpose |\n|---|---|\n| `DEEPAGENT_MODEL_PROVIDER` | Server fallback model provider: `openrouter`, `gemini`, `nebius`, `huggingface`, `custom`, or `local` |\n| `DEEPAGENT_MODEL` | Server fallback model ID. Must prove `<=32B` when selected per Run. |\n| `DEEPAGENT_MODEL_BASE_URL` | Optional OpenAI-compatible `/v1` endpoint |\n| `OPENROUTER_API_KEY` / `GEMINI_API_KEY` / `NEBIUS_API_KEY` / `HF_TOKEN` | Optional server fallback keys for trusted server/CLI runs only. The public Gradio UI requires the user to enter their own hosted-provider key and does not use these by default. |\n| `DEEPAGENT_SANDBOX_PROVIDER` | `local`, `docker`, or `daytona` |\n| `BROWSERBASE_API_KEY` | Optional — visual validation via Stagehand |\n| `UPSTASH_REDIS_REST_URL` / `TOKEN` | Optional — persistent runs & archives |\n\n---\n\n## Stack\n\n- **Python 3.11+** /

You can play the\nintended way by reading only the capsule, adding one fragment, and letting\n`Qwen/Qwen3.5-2B` decide where that fragment belongs. The model rewrites only the\nlocal passage it targets, then reveals where your idea was stitched into the\nstory.\n\nReaders who only want to read can use the escape door: `Read without changing`.\nThe app warns that the best experience is to contribute first, then allows the\nreader to reveal the full manuscript anyway.\n\n## Interface\n\nThe UI is a bespoke literary frontend called \"The Invisible Bindery\". It lives in\n`web/` and is served by a `gradio.Server` backend.\n\n`app.py` exposes queued API endpoints:\n\n- `list_stories`\n- `get_capsule`\n- `create_story`\n- `stitch`\n- `read_manuscript`\n\nThe frontend calls those endpoints through the Gradio JS client. This keeps\nGradio queueing, concurrency control, and ZeroGPU support while presenting a\nsingle custom surface: gallery -> capsule -> compose -> reveal -> reader.\n\nThe Python layers are:\n\n- `core.py`: create, browse, stitch, and read orchestration.\n- `story_store.py`: JSON persistence and file locking.\n- `model_client.py`: model loading, generation, thinking-block stripping, and\n JSON validation.\n- `patcher.py`: deterministic local patch application.\n- `presenter.py`: view models for the custom frontend.\n- `app.py`: static frontend serving and Gradio Server API endpoints.\n\n## Local Development\n\nUse uv with Python 3.12, matching the Hugging Face Space as closely as possible.\n\n```bash\nuv sync --python 3.12\nuv run python app.py\n```\n\nThen open .\n\nPersistent story data is stored at:\n\n- `DATA_DIR`, when set\n- `/data`, when it exists on Hugging Face Spaces\n- `./data/stories.json`, otherwise\n\n### Execution backend\n\n`BQ_DEVICE` selects where generation runs.\n\n| `BQ_DEVICE` | Behaviour |\n| --- | --- |\n| `auto` (default) | ZeroGPU on a Space with the `spaces` runtime, else CUDA, else Apple MPS, else CPU. |\n| `zerogpu` | Hugging Face ZeroGPU (`@spaces.GPU`), with automatic CPU fallback (below). |\n| `cuda` | Local NVIDIA GPU via `device_map=\"auto\"`. |\n| `mps` | Apple Silicon GPU (Metal); falls back to float32 if float16 fails. |\n| `cpu` | CPU only — slow but needs no accelerator or quota. |\n\n**Per-user ZeroGPU fallback.** ZeroGPU quota is per visitor, not per Space owner,\nand is only known at request time. So on a ZeroGPU Space each stitch is attempted\non the GPU; if the visitor's quota is spent, the request is transparently re-run\non CPU instead of failing. No configuration or sign-in is required to keep using\nthe app — it just gets slower.\n\n**Progress.** Because CPU/MPS runs are slow, the `stitch` endpoint streams real\nprogress (stage, percentage, ETA — and a note when a fallback happens) to the\nreveal screen. Fast GPU runs keep the original staged animation, since ZeroGPU's\nforked generation cannot stream token callbacks back across the process boundary.\n\n### Logging\n\nSet `BQ_LOG_LEVEL` (default `INFO`; use `DEBUG` for per-stage detail). Logs go to\nstderr only — never the UI — and record messages processed, total and per-stage\ntimings, and a best-effort resource snapshot (process memory, CPU, and GPU/MPS\nmemory when available).\n\n## Requirements\n\n`requirements.txt` is generated from `uv.lock` for Hugging Face Spaces:\n\n```bash\nuv export --format requirements-txt --no-dev --no-hashes --no-emit-project -o requirements.txt\n```\n\nDo not hand-edit `requirements.txt`; edit `pyproject.toml`, run `uv lock`, and\nexport again.\n\n## Test\n\n```bash\nuv run python -m compileall app.py core.py model_client.py observability.py patcher.py presenter.py prompts.py schemas.py story_store.py utils.py tests\nuv run python -m unittest discover -s tests -v\n```\n\nThe tests cover JSON/thinking cleanup, deterministic patch application, graft\nsealing, stale-write rejection, the blinded capsule flow, the warned read escape\ndoor, the create-then-stitch flow, device resolution, the resource snapshot, and\nthe streamed stitch progress events. They do not download model weights.\n\n## Model Policy\n\n- Uses one model: `Qwen/Qwen3.5-2B`.\n- Uses the Transformers `AutoProcessor` and `AutoModelForImageTextToText` path.\n- Wraps model generation in `@spaces.GPU(duration=300)` on ZeroGPU; runs directly\n on CUDA, MPS, or CPU otherwise (selected by `BQ_DEVICE`).\n- Does not set `temperature`, `top_p`, `top_k`, or other sampling controls.\n- Disables Qwen thinking for schema-constrained JSON calls so the token budget is\n spent on parseable JSON; other text generation keeps the model template default.\n- Strips `...` before JSON parsing, storage, prompting, or UI\n rendering.\n- Does not use embeddings, RAG, ASR, image models, or a second language model.\n\n## Example Seeds\n\n```text\nA city where every doorway remembers the last person who lied inside it.\n```\n\n```text\nOn a generation ship whose crew believes Earth was a myth invented to calm children, a janitor discovers a sealed garden where rain falls upward and an old radio is still receiving ocean weather reports.\n```\n\nExample fragment:\n\n```text\nA brass key in the protagonist's pocket becomes warm whenever someone nearby tells the truth.\n```\n", + "readme_body": "# Blind Quill\n\nBlind Quill is a hidden-canon story grafting game.\n\nEach manuscript has a public capsule and a hidden full canon.

Borderless puts it in one conversational flow:\n\n1. **Describe yourself** — citizenship, education, work history, languages, budget, and goals in everyday language.\n2. **Use guided intake or chat** — start from a structured profile form, a demo persona, or a free-form message.\n3. **Get a shortlist** — the agent reasons over your profile and surfaces destination countries that fit.\n4. **Explore on a 3D globe** — shortlisted countries appear on an interactive MapLibre globe beside the chat with pathway labels.\n5. **Dig into the details** — visa pathways, required documents, realistic timelines, risks, and source links from official pages.\n\nNo forms to decode. No keyword guessing. Just a research session that meets you where you are.\n\n## How it works\n\nBorderless is a **Gradio agent** powered by **[Qwen/Qwen3.6-27B](https://huggingface.co/Qwen/Qwen3.6-27B)** (27B parameters — within the hackathon's 32B cap). The model plans multi-step research and calls tools when it needs ground truth:\n\n| Tool | What it fetches |\n|------|-----------------|\n| `get_country_profile` | Country metadata and official immigration domain hints (REST Countries + curated hints) |\n| `search_immigration_info` | Web search with source-quality labels for official immigration pages, policies, and pathways (Exa) |\n| `scrape_web_page` | Markdown content from a specific official government or embassy URL (Firecrawl) |\n| `crawl_web_site` | Multiple pages from an official immigration website section (Firecrawl) |\n| `update_globe` | Marks, highlights, and flies to countries on the MapLibre globe |\n\nTool calls stream in the chat so you can follow the agent's progress. Globe updates are also tool-driven: when the agent recommends destinations or the user asks to mark countries, it sends ISO country codes and pathway labels to the map. The default research budget is seven tool rounds, then Borderless synthesizes a clear answer with pathways, documents, timelines, risks, and cited sources.\n\nSign in with your Hugging Face account to run inference through the Inference API.\n\n## Features\n\n- **Guided intake** — form fields turn citizenship, education, work, languages, budget, and goals into a complete research prompt\n- **Agentic research** — multi-turn tool use, not a single-shot prompt\n- **Structured recommendations** — shortlist, pathways, documents, risks, timelines, next steps, and official sources\n- **Tool-driven 3D globe** — MapLibre GL globe projection with markers, highlights, pathway labels, fly-to camera moves, drag, rotate, and zoom\n- **Source quality** — search results identify likely official government, embassy, and unofficial context sources\n- **Web search** — Exa discovers official immigration pages, visa rules, and policy sources\n- **Official page scraping** — Firecrawl extracts markdown from government immigration sites\n- **Country metadata** — REST Countries powers ISO-2 / ISO-3 lookup and map coordinates\n- **Transparent traces** — tool progress is visible in chat, and JSONL traces can be sanitized and shared\n- **Chat history** — pick up where you left off in the sidebar\n\n## Example prompts\n\n- *\"I'm a software engineer from India with 5 years of experience and a master's degree. Where could I realistically relocate for work?\"*\n- *\"I hold a Hong Kong passport and want to study in Europe on a modest budget.
