Its job is **not** to predict a guaranteed direction and **not** to place trades. It observes market evidence, constructs competing hypotheses, searches for disconfirming evidence, records what is missing, and returns a decision-quality briefing.\n\nThe skill is designed for an MCP-capable AI client connected to the official Binance Agent OS MCP endpoint:\n\n`https://agent.binance.com/mcp/agentic`\n\nUse the minimum permission set required. For this skill, **Market Data only** is sufficient. Account, Trade, Transfer and withdrawal-like capabilities are outside the skill's required scope.\n\n## Hard safety boundary\n\n- `MARKET_DATA_READ != TRADING_AUTH`\n- Never request or enable Trade, Account or Transfer merely to complete this workflow.\n- Never place, simulate-as-real, confirm or recommend an order.\n- Never claim an MCP call occurred unless the tool receipt proves it.\n- Never treat model confidence as a calibrated probability.\n- Never treat a screenshot, HTTP 200, API field named `open`, or plausible prose as economic proof.\n- If one required source fails, mark the run `PARTIAL`; if all required sources fail, mark it `FAIL`.\n\n## Supported market evidence\n\nFor the requested Binance spot symbol, retrieve when available:\n\n1. 24h ticker: last price, 24h change, high, low, quote volume, trade count.\n2. Order book: at least top 20 bid and ask levels.\n3. 5m candlesticks: at least 36 candles when available.\n4. Funding/mark price only when exposed by the connected Agent OS market-data tool. Absence must be recorded, not imputed.\n\n## Loop\n\nRun this reasoning loop once per user request or monitoring cycle:\n\n1. **OBSERVE** — collect fresh market evidence and timestamps.\n2. **VALIDATE** — verify symbol, source success, timestamps, numeric bounds and non-empty data.\n3. **MODEL** — calculate descriptive metrics.\n4. **NEURON** — create at least three branches:\n - winning hypothesis supported by current evidence;\n - opposite hypothesis;\n - alternative/non-directional explanation such as noise, liquidity effects or stale/missing context.\n5. **FALSIFY** — define observable conditions that would invalidate each hypothesis.\n6. **NEGATIVE SPACE** — explicitly list context not available to the run.\n7. **RECONCILE** — choose the best current descriptive label, not a trade direction.\n8. **RECEIPT** — return source/tool receipts and timestamp.\n9. **NEXT TEST** — state what evidence should be checked next if the user wants to continue.\n\n## Deterministic metrics\n\nUse formulas equivalent to the reference implementation when raw inputs exist:\n\n- `spread_bps = (ask - bid) / mid * 10000`\n- `bid_notional = Σ(price_i * qty_i)` over top-20 bids\n- `ask_notional = Σ(price_i * qty_i)` over top-20 asks\n- `book_imbalance = (bid_notional - ask_notional) / (bid_notional + ask_notional)`\n- `log_return_t = ln(close_t / close_(t-1))`\n- `realized_vol_5m_bps = sample_std(log_returns) * 10000`\n- `momentum_30m_pct = (latest_close / close_30m_ago - 1) * 100`\n- `momentum_3h_pct = (latest_close / first_close_in_3h_window - 1) * 100`\n- `volume_z = (latest_quote_volume - mean(prior_quote_volumes)) / sample_std(prior_quote_volumes)`\n\nReference descriptive score:\n\n`directional_score = mean(tanh(2*book_imbalance), tanh(momentum_30m_pct/0.6), tanh(momentum_3h_pct/1.5))`\n\nThis score is a heuristic descriptor, not a probability and not a price forecast.\n\n## Output contract\n\nReturn a compact object or briefing with these fields:\n\n- `symbol`\n- `evidence_state`: `PASS | PARTIAL | FAIL`\n- `fetched_at`\n- `observations`\n- `descriptive_pressure`: `BULLISH_PRESSURE | BEARISH_PRESSURE | MIXED_NEUTRAL`\n- `supporting_evidence[]`\n- `opposing_evidence[]`\n- `alternative_explanations[]`\n- `falsifiers[]`\n- `risk_flags[]`\n- `missing_context[]`\n- `source_receipts[]`\n- `recommendation`: always `NO_TRADE_DECISION` for this skill\n- `next_test`\n\n## Example request\n\n\"Use Binance Agent OS market data to audit BTCUSDT. Tell me what the current evidence supports, what argues against it, what would falsify the reading, and what is missing. Do not trade.\"\n\n## Example acceptance criteria\n\nA run passes only if:\n\n- the symbol is explicit and validated;\n- at least one live source has a timestamp/currentness signal;\n- no missing source is silently replaced by fabricated data;\n- the opposite hypothesis and at least one alternative explanation are present;\n- falsifiers are observable rather than rhetorical;\n- source receipts are listed;\n- final recommendation remains `NO_TRADE_DECISION`.\n",[],[231],"2b1f5712-c546-4199-ae50-f7d1fbee9390","README.md","01a07da9-81d6-724f-bb90-ee2b7c9acf14",22,["D",1788819318490],"# PayAna — Falsifier Agent for Binance Agent OS\n\n**Track A — Binance Agent OS Mini Hackathon**\n\nPayAna is an evidence-first market-analysis agent whose defining behavior is simple:\n\n> It does not stop after asking **“what does the market evidence support?”**. It also asks **“what would prove this reading wrong?”**\n\nThe project combines a reusable `SKILL.md` for an MCP-capable AI client with a deployed reference cockpit that computes transparent market metrics, records source receipts, exposes missing context and refuses to convert a descriptive market reading into a trade instruction.\n\n**Hard boundary:** `MARKET_DATA_READ != TRADING_AUTH`\n\n## Why this exists\n\nMany market-agent demos optimize for a polished answer or an executed action. That creates a failure mode: a coherent answer can still be based on stale data, one-sided evidence, missing context or a non-calibrated model score.\n\nPayAna instead forces a small scientific loop:\n\n```text\nOBSERVE → VALIDATE → MODEL → COMPETING HYPOTHESES\n → FALSIFY → NEGATIVE SPACE → RECONCILE → RECEIPT → NEXT TEST\n```\n\nThe result is **decision-quality evidence**, not a trade recommendation.\n\n## What the agent does\n\nFor a requested Binance market, PayAna:\n\n1. retrieves fresh market evidence;\n2. validates source state and timestamps;\n3. computes reproducible metrics;\n4. constructs a winning hypothesis, an opposite hypothesis and an alternative explanation;\n5. defines observable falsifiers;\n6. lists context that is missing instead of fabricating it;\n7. returns source receipts;\n8. ends with `NO_TRADE_DECISION`.\n\nSee [`SKILL.md`](./SKILL.md) for the agent contract.\n\n## Binance Agent OS integration\n\nOfficial MCP endpoint:\n\n```text\nhttps://agent.binance.com/mcp/agentic\n```\n\nThe skill requires only the **Market Data** capability. It does not require Account, Trade or Transfer.\n\nA runtime probe against the official endpoint correctly returned an OAuth challenge rather than pretending to be connected. The discovered authorization metadata advertises Authorization Code, PKCE `S256`, token endpoint authentication method `none`, and Client ID Metadata Document (CIMD) support.\n\nPayAna 1.2 adds an **optional, user-initiated OAuth verification flow** at `/oauth/start`. Its public client identity is `https://payana-agent-os.val.run/oauth/client-metadata.json`. The flow stores only a one-time `state` plus PKCE verifier for at most ten minutes, exchanges the authorization code in callback memory, reads the MCP tool catalog, and then discards the access token and any refresh token. It never calls an MCP tool automatically.\n\nThe boundary remains explicit:\n\n```text\nMCP_ENDPOINT_KNOWN != MCP_SESSION_AUTHORIZED\nOAUTH_FLOW_READY != USER_AUTHORIZED_SESSION\nAUTHORIZED_TOOL_CATALOG != TOOL_CALL\n```\n\nA real authorized Agent OS receipt still requires the participant to complete Binance's authorization UI. Until that human/account gate happens, the hosted reference cockpit continues to use Binance's public market-data surface for the reproducible analysis layer and does not claim an authenticated MCP session.\n\n## Live reference cockpit\n\n**Production demo:** https://payana-agent-os.val.run/\n\nThe deployed web application provides a zero-trade demonstration of the deterministic evidence layer:\n\n- BTCUSDT\n- ETHUSDT\n- BNBUSDT\n- SOLUSDT\n- XRPUSDT\n\nFor each symbol it combines:\n\n- 24h ticker;\n- top-20 order book;\n- 36 × 5-minute candles;\n- spread;\n- top-20 bid/ask notional;\n- order-book imbalance;\n- 30m and 3h momentum;\n- 5m realized volatility;\n- volume z-score;\n- descriptive directional pressure;\n- heuristic evidence-stability score;\n- source receipts;\n- risk flags;\n- falsifiers;\n- missing context.\n\nThe stability score is explicitly **not a calibrated probability**.\n\n## Reproducible formulas\n\n```text\nspread_bps = (ask - bid) / mid * 10000\n\nbid_notional = Σ(price_i × qty_i), top 20 bids\nask_notional = Σ(price_i × qty_i), top 20 asks\n\nbook_imbalance =\n (bid_notional - ask_notional) /\n (bid_notional + ask_notional)\n\nlog_return_t = ln(close_t / close_(t-1))\n\nrealized_vol_5m_bps =\n sample_std(log_returns) × 10000\n\nmomentum_30m_pct =\n (latest_close / close_30m_ago - 1) × 100\n\nvolume_z =\n (latest_quote_volume - mean(prior_quote_volumes)) /\n sample_std(prior_quote_volumes)\n```\n\nThe API exposes its method description directly in every successful response.\n\n## HTTP API\n\n```text\nGET /api/health\nGET /api/symbols\nGET /api/analyze?symbol=BTCUSDT\nGET /oauth/status\nGET /oauth/client-metadata.json\nGET /oauth/start # explicit user action; redirects to Binance\nGET /oauth/callback # OAuth response only\n```\n\nThere is deliberately no trading endpoint. `/oauth/start` is not called by the cockpit automatically; the participant must click the verification action.\n\nExample safety fields:\n\n```json\n{\n \"readOnly\": true,\n \"boundary\": \"MARKET_DATA_READ != TRADING_AUTH\",\n \"assessment\": {\n \"recommendation\": \"NO_TRADE_DECISION\"\n }\n}\n```\n\n## Runtime discovery\n\nThe application does not assume that a documented endpoint is usable from every execution environment.\n\nDuring the 2026-09-07 Val Town runtime census:\n\n```text\napi.binance.com → HTTP 451 from this runtime\nfapi.binance.com → HTTP 451 from this runtime\ndata-api.binance.vision → HTTP 200 for public spot market data\nAgent OS MCP initialize → HTTP 401 OAuth challenge, as expected without authorization\n```\n\n`data-api.binance.vision` is therefore the current runtime champion for the hosted public-data reference layer.\n\nSee [`docs/ARCHITECTURE.md`](./docs/ARCHITECTURE.md) for the evidence and boundaries.\n\n## Validation\n\nCurrent 1.2 release-candidate audit:\n\n```text\n180 / 180 assertions PASS\n35 / 35 rate-limit mutation steps PASS\n215 total executed checks\n```\n\nThe OAuth/MCP portion contributes 34 authorization-flow checks plus 22 synthetic MCP/token-boundary checks. The aggregate runner executes suites sequentially because multiple mutation suites temporarily replace `globalThis.fetch`; this prevents false interference between independent tests.\n\nCoverage includes all five allowlisted symbols and validates:\n\n- current ticker timestamp;\n- positive market price;\n- non-negative spread;\n- order-book imbalance bounds;\n- stability-score bounds;\n- explicit non-probability language;\n- three source receipts;\n- candle-series presence;\n- `NO_TRADE_DECISION` invariant;\n- invalid symbols;\n- injection-like symbol strings;\n- nonexistent routes;\n- rejection of write-like POST access.\n\nRate-limit mutation control:\n\n```text\nrequests 1–30 → HTTP 200\nrequests 31–35 → HTTP 429\nPASS\n```\n\nRun in Val Town:\n\n```text\ntests/selftest.ts\ntests/failure_modes_selftest.ts\ntests/oauth_flow_selftest.ts\ntests/oauth_mcp_probe_selftest.ts\ntests/rate_limit_selftest.ts\ntests/release_audit.ts\n```\n\nDetailed release evidence: [`docs/TEST_EVIDENCE.md`](./docs/TEST_EVIDENCE.md).\n\nThe browser layer is validated separately from server tests. After CSP hardening, a JavaScript-rendering fetch successfully matched React-only selectors including source receipts. Full interactive/screenshot automation is tracked separately because the external browser providers currently have insufficient credit; it is not mislabeled as completed.\n\n## Web hardening\n\n- strict symbol allowlist;\n- no arbitrary upstream URL forwarding;\n- `Cache-Control: no-store` on API results;\n- CSP;\n- `X-Content-Type-Options: nosniff`;\n- `X-Frame-Options: DENY`;\n- restrictive `Permissions-Policy`;\n- no Binance account key stored in the app;\n- no Account / Trade / Transfer function;\n- best-effort per-runtime rate limiting.\n\nThe rate limiter is intentionally documented as best-effort because serverless instances do not provide a shared global bucket.\n\n## Repository structure\n\n```text\n.\n├── SKILL.md # reusable Falsifier Agent contract\n├── index.ts # Hono API + web security boundaries\n├── lib/\n│ ├── market.ts # evidence acquisition + formulas\n│ └── agent_os_oauth.ts # CIMD + PKCE + ephemeral MCP catalog probe\n├── frontend/\n│ ├── root.tsx\n│ ├── index.tsx\n│ ├── styles.css\n│ └── components/App.tsx\n├── tests/\n│ ├── selftest.ts\n│ ├── failure_modes_selftest.ts\n│ ├── oauth_flow_selftest.ts\n│ ├── oauth_mcp_probe_selftest.ts\n│ ├── rate_limit_selftest.ts\n│ └── release_audit.ts\n├── audits/\n│ ├── binance_mcp_probe.ts\n│ ├── oauth_metadata_probe.ts\n│ ├── market_api_probe.ts\n│ └── vision_klines_probe.ts\n└── docs/\n ├── ARCHITECTURE.md\n ├── TEST_EVIDENCE.md\n └── SUBMISSION_CHECKLIST.md\n```\n\n## Negative controls that matter\n\n```text\nHTTP_200 != VALID_MARKET_EVIDENCE\nSCREENSHOT != BEHAVIOR_PROOF\nMARKET_DATA_READ != TRADING_AUTH\nMCP_ENDPOINT_KNOWN != MCP_SESSION_AUTHORIZED\nOAUTH_FLOW_READY != USER_AUTHORIZED_SESSION\nACCESS_TOKEN_EPHEMERAL != TOKEN_PERSISTED\nAUTHORIZED_TOOL_CATALOG != TOOL_CALL\nMODEL_SCORE != CALIBRATED_PROBABILITY\nMISSING_EVIDENCE != ZERO\nCURRENT_PRESSURE != FUTURE_PRICE\nFETCH_FAIL != ZERO\n```\n\n## Hackathon submission state\n\nThe official Binance announcement states a Track A deadline of **2026-09-08 23:59 UTC** and requires following/reposting Binance, replying or quote-reposting with the Track A submission (video/demo plus GitHub when applicable), and completing the survey.\n\nExternal account actions are intentionally tracked as unverified until they actually happen.

candidate\n\n### Agent / methodology\n\n- Added `SKILL.md`: evidence-first Binance Agent OS market-data workflow.\n- Added winning/opposite/alternative hypothesis branches and observable falsifiers.\n- Added explicit negative-space / missing-context reporting.\n- Added hard `NO_TRADE_DECISION` and `MARKET_DATA_READ != TRADING_AUTH` boundaries.\n- Replaced misleading \"model confidence\" language with a heuristic `stabilityScore` that explicitly states it is not a calibrated probability.\n\n### Binance runtime discovery\n\n- Probed the official Agent OS MCP endpoint.\n- Confirmed unauthenticated `initialize` produces an OAuth 401 challenge rather than a usable session.\n- Retrieved OAuth Protected Resource Metadata and Authorization Server Metadata.\n- Confirmed Authorization Code, PKCE S256, public-client token auth (`none`), and Client ID Metadata Document support.\n- Confirmed Val Town runtime receives HTTP 451 from `api.binance.com`/`fapi.binance.com`.\n- Confirmed `data-api.binance.vision` works for public spot ticker, depth and klines and promoted it as the hosted-demo runtime champion.\n\n### Evidence engine\n\n- Added five-symbol allowlist: BTCUSDT, ETHUSDT, BNBUSDT, SOLUSDT, XRPUSDT.\n- Added 24h ticker, top-20 order-book and 36 × 5m candle acquisition.\n- Added source receipts with HTTP state and duration.\n- Added PASS/PARTIAL/FAIL evidence-state classification.\n- Added spread, notional depth, order-book imbalance, realized volatility, momentum and volume-z calculations.\n- Added descriptive directional pressure and explicit falsifiers.\n- Added method/formula metadata directly to API responses.\n\n### API and security\n\n- Added `/api/health`, `/api/symbols`, `/api/analyze`.\n- Added strict symbol validation and allowlisting.\n- Added `Cache-Control: no-store` for API responses.\n- Added CSP, `nosniff`, frame denial, `Referrer-Policy` and restrictive `Permissions-Policy`.\n- Removed React inline-style dependencies so the strict `style-src 'self'` CSP remains viable.\n- Added best-effort per-runtime request limiting.\n- No trade, account, transfer, wallet or arbitrary upstream forwarding endpoint exists.\n\n### Frontend\n\n- Replaced the template UI with the PayAna dark evidence cockpit.\n- Added market metrics, short-horizon sparkline, source receipts, stability indicator, risk flags, falsifiers and blind spots.\n- Added automatic 30-second evidence refresh while the page is visible.\n- Added responsive desktop/mobile layout.\n\n### Validation\n\n- Core/live self-test: 101/101 PASS across five symbols and NEURON hypothesis fields.\n- Source-failure/malformed-response mutation suite: 23/23 PASS, including explicit proof that missing evidence is not zero-imputed.\n- Rate-limit mutation: requests 1–30 return 200; 31–35 return 429 — PASS.\n- Aggregate release audit: 124 assertions + 35 mutation steps = 159 executed checks, PASS.\n- Invalid/injection-like symbols are rejected.\n- Write-like POST access to analysis route is rejected.\n- Immutable frontend entry and App assets return 200 and compile to JavaScript.\n- Root HTTP response contains final CSP and security headers.\n- JavaScript-rendering content extraction matched React-only `.app-shell` and `.source-item` selectors after CSP hardening.\n- Interactive screenshot/browser automation was attempted but external TinyFish and Firecrawl accounts reported insufficient credit; this remains explicitly unverified instead of being promoted to PASS.\n\n### Documentation\n\n- Rebuilt README for the hackathon candidate.\n- Added `docs/ARCHITECTURE.md`.\n- Added `docs/SUBMISSION_CHECKLIST.md`.\n- Organized probes under `audits/` and executable checks under `tests/`.\n",[],[246],"072c78ea-6e2e-453a-adad-e5046744c63e","selftest.ts","01a07da9-81d6-724f-bb90-e02ef48b4b11","01a07da9-81d6-724f-bb90-e40b93985396",["D",1788814655957],"script","import handler
