Binance says Track A means a video or demo plus GitHub **if applicable**.\n- The event page explicitly excludes the US, UK, EEA, Hong Kong, Singapore and Binance-prohibited jurisdictions. **Brazil is not explicitly named in that exclusion sentence, but participant/account eligibility is still UNVERIFIED until the logged-in Binance flow accepts the account.**\n- Official MCP docs classify Market Data as **public, no auth** at the capability level, but the supported-client MCP server connection still has an authentication step. Do not equate public data capability with an anonymously usable MCP catalog.\n- Official supported clients include ChatGPT on the web, ChatGPT/Codex Desktop, Codex CLI, Claude Code/Desktop, VS Code and Grok Bot.\n- Binance's official connection check is: ask the client to use the Binance MCP Server for current BTCUSDT price + 24-hour change, then verify that the response visibly shows the Binance MCP tool and live market data.\n- The official docs say **do not paste the MCP endpoint into a chat and ask the model to install it**, and do not open the MCP endpoint directly in a browser; use the client's MCP/plugin setup flow.\n- Market-data reads run without a trading confirmation; every trade/transfer requires confirmation, and withdrawal scope is never available. PayAna does not need Trade, Account or Transfer for the Track A read-only demo.\n\nOfficial references:\n\n- Hackathon: `https://www.binance.com/en/blog/community/8802181509900814931`\n- Agent OS: `https://www.binance.com/en/agent-os`\n- MCP docs: `https://developers.binance.com/en/docs/agent-native/mcp-server/agentic`\n\n## What differentiates PayAna\n\n1. **Falsification instead of answer-only confidence.** Every market briefing contains a winning/current hypothesis, the opposite hypothesis, an alternative mechanism, supporting evidence, opposing evidence, observable falsifiers and a next discriminating test.\n2. **Missing evidence is not fabricated evidence.** Failed or malformed sources become `null` and are excluded from aggregation; they never silently become zero.\n3. **Traceable evidence.** Ticker, top-20 order book and 5-minute candle reads produce explicit source receipts with HTTP state and latency.\n4. **Currentness-aware.** Live timestamps are checked and the UI automatically refreshes while visible.\n5. **No trading authority required.** The reference cockpit uses read-only Binance market evidence and has no Trade, Account, Transfer, wallet or arbitrary upstream action endpoint.\n6. **Agent OS integration is fail-closed.** The optional MCP/OAuth verification path uses CIMD + Authorization Code + PKCE S256, one-time state, no persistent Binance token and no automatic `tools/call`.\n7. **Negative controls are part of the product.** Invalid symbols, malformed HTTP-200 responses, total/partial provider failure, replay, concurrent OAuth state consumption, MCP dangerous-tool classification and rate limiting are executable tests, not documentation-only claims.\n\n## 75–90 second video plan\n\n### 0–8s — problem\n\nScreen: PayAna landing view.\n\nNarration:\n\n> Most market agents optimize for producing an answer.

Missing or malformed evidence never becomes zero, and a partially available market does not receive fabricated certainty.

If the resulting post is too long, use this compact version:\n\n> Track A — Binance Agent OS Mini Hackathon\n>\n> PayAna is an evidence-first Falsifier Agent: live Binance evidence, competing hypotheses, source receipts, observable falsifiers and NO_TRADE_DECISION.\n>\n> Demo: https://payana-agent-os.val.run/\n> Video: [VIDEO_URL]\n> GitHub: [GITHUB_URL]\n>\n> @Binance #BinanceAgentOS\n\n## Survey answer draft\n\n### Project name\n\nPayAna — Falsifier Agent for Binance Agent OS\n\n### Project description\n\nPayAna is an evidence-first market-analysis agent built around falsification rather than answer-only confidence. It collects current Binance market evidence, validates source state and timestamps, computes reproducible microstructure and momentum metrics, and then produces competing hypotheses instead of one narrative. Every briefing includes supporting and opposing evidence, alternative explanations, observable falsifiers, missing context and a concrete next test. The reference cockpit is intentionally read-only and ends with NO_TRADE_DECISION.\n\n### What problem does it solve?\n\nAI market analysis can sound coherent even when it is based on stale, incomplete or malformed data. PayAna makes these failure modes visible. Missing evidence is never silently converted to zero, partial evidence is explicitly labeled, source receipts are exposed and each conclusion is paired with conditions that could invalidate it.\n\n### How does it use Binance / Agent OS?\n\nPayAna is designed around Binance Agent OS Market Data as the market-evidence capability. The hosted reference implementation uses Binance's public Spot market-data surface for reproducible live analysis. An optional Agent OS connection-verification path implements current OAuth/CIMD/PKCE boundaries without persisting Binance tokens or invoking tools automatically. If the final supported-client MCP proof is completed, add the exact client/tool evidence here rather than making a generic claim.\n\n### Safety / permissions\n\nPayAna does not need Account, Trade or Transfer authority for its Track A workflow. The hosted reference has no trade endpoint, no wallet action and no persistent Binance access token. Its hard boundary is `MARKET_DATA_READ != TRADING_AUTH`.\n\n### Demo URL\n\nhttps://payana-agent-os.val.run/\n\n### Source URL\n\n[GITHUB_URL if created; otherwise use the public Val Town source link if the form accepts it]\n\n### Video URL\n\n[VIDEO_URL]\n\n## Minimal supported-client MCP proof — exact witness\n\nUse the official Binance MCP setup flow in a **desktop** supported client. Keep the PayAna proof read-only and permission-minimized.\n\n1. In the client's MCP/plugin settings, add the official Binance MCP server using the documented client flow. Do not paste the endpoint into the normal chat as an instruction.\n2. Authenticate the server through the Binance browser flow.\n3. Grant only the minimum capability required for the witness. For PayAna, the target is Market Data; do not enable Trade or Transfer merely for the demo.\n4. Return to the client and ask exactly: `Use the Binance MCP Server to show the current BTCUSDT price and 24-hour change.`\n5. Capture one screenshot or short clip where the **Binance MCP tool attribution is visible** and live BTCUSDT market data is returned.\n6. Record client name, UTC timestamp and the visible tool/result in the PayAna receipt ledger. Never record authorization codes, cookies, access/refresh tokens or account secrets.\n7. If the client forces creation/selection of an Agentic sub-account during authentication, complete only the required account onboarding; **do not fund it for Track A read-only evidence unless Binance explicitly requires funding for eligibility**. Official docs only require funding before trading.\n\nExpected classification after a clean witness:\n\n```text\nSUPPORTED_CLIENT_MCP_CONNECTION = VERIFIED\nMARKET_DATA_TOOL_USE = VERIFIED\nACCOUNT_SCOPE = NOT_REQUIRED_FOR_PAYANA\nTRADE_SCOPE = NOT_GRANTED\nTRANSFER_SCOPE = NOT_GRANTED\nNO_TRADE_DECISION = TRUE\n```\n\n## Human/account gates — do not mark complete without receipt\n\n- [ ] Confirm participant/account eligibility for the hackathon.\n- [ ] Connect Binance Agent OS in a supported MCP client and capture a real Market Data tool proof if feasible.\n- [ ] Record the final video/demo.\n- [ ] Create/publish GitHub mirror if desired/applicable and verify its URL.\n- [ ] Follow `@Binance` on X.\n- [ ] Repost the official hackathon announcement.\n- [ ] Reply or quote-repost with the Track A submission.\n- [ ] Complete the official Binance survey.\n- [ ] Preserve the final X post URL, survey completion receipt, video URL and GitHub URL in PayAna's durable receipt ledger.\n\n## Final anti-overclaim checklist\n\nBefore submission, the language must satisfy all of these:\n\n```text\nPUBLIC_API_PASS != MCP_CONNECTION_PROOF\nMCP_ENDPOINT_KNOWN != MCP_SESSION_AUTHORIZED\nAUTHORIZATION_SURFACE_REACHABLE != CIMD_ACCEPTED\nMODEL_SCORE != CALIBRATED_PROBABILITY\nCURRENT_PRESSURE != FUTURE_PRICE\nMISSING_EVIDENCE != ZERO\nSCREENSHOT != BEHAVIOR_PROOF\nNO_TRADE_DECISION remains true\n```\n\nThe submission is ready when the technical package remains green and each required external account step has an actual receipt, not merely a planned action.\n","# PayAna — Track A Submission Package\n\nStatus checkpoint: **2026-09-07 19:35 BRT**\n\nOfficial Track A deadline: **2026-09-08 23:59 UTC / 20:59 BRT**.\n\nThis document is the final handoff package for the human/account steps that cannot be truthfully automated from the PayAna runtime.\n\n## Submission identity\n\n**Project:** PayAna — Falsifier Agent for Binance Agent OS\n\n**Track:** A — Build an AI agent using Agent OS\n\n**One-line pitch:** PayAna is an evidence-first market-analysis agent that does not merely state what the market appears to support; it exposes the evidence against its own conclusion, explicit falsifiers, missing context and the next test that could prove it wrong.\n\n**Live demo:** https://payana-agent-os.val.run/\n\n**Machine-readable submission evidence:** https://payana-agent-os.val.run/api/submission-evidence\n\n**Technical release:** `payana-market-sentinel-1.2.0-rc1`\n\n**Validation receipt:** 189 assertions + 35 rate-limit mutation steps = **224 executed checks PASS**.\n\n**Safety boundary:** `MARKET_DATA_READ != TRADING_AUTH` and every analysis ends with `NO_TRADE_DECISION`.\n\n## Official currentness checkpoint — 2026-09-07\n\nVerified against the Binance Mini Hackathon announcement and the Binance Developer MCP page, which was last modified on 2026-09-07:\n\n- Track A closes at **2026-09-08 23:59 UTC / 20:59 BRT**.\n- Track A entry requires following `@Binance`, reposting the announcement, replying or quote-reposting with the submission, and completing the official survey.

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.

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 direct unauthenticated MCP transport probe also found that the deployed Agent OS server currently returns JSON-RPC `Method not found` for modern `server/discover` and HTTP 401 + OAuth resource metadata for `tools/list`. So Binance's \"Market Data: public, no auth\" capability should not be confused with an anonymously accessible MCP tool catalog: the connection is still authorization-gated in this runtime. A real Agent OS connection receipt therefore still requires the participant to complete the supported MCP-client connection/authentication flow. Until that gate happens, the hosted reference cockpit continues to use Binance's documented public market-data API surface for the reproducible analysis layer and does not claim an authenticated MCP session.\n\nCurrent Binance Developer documentation lists supported MCP clients including ChatGPT on the web, ChatGPT/Codex Desktop, Codex CLI, Claude Code/Desktop, VS Code and Grok Bot. Its own connection witness is a read-only request for current BTCUSDT price and 24-hour change, with the Binance MCP tool attribution visibly present in the client response. PayAna uses that exact witness as the remaining MCP proof gate; Account, Trade and Transfer are not needed for the Track A read-only workflow.\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/submission-evidence # machine-readable Track A evidence manifest\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\n189 / 189 assertions PASS\n35 / 35 rate-limit mutation steps PASS\n224 total executed checks\n```\n\nThe OAuth/MCP portion contributes 34 authorization-flow checks, 25 synthetic MCP/token-boundary checks and 6 OAuth-state storage/replay 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/oauth_state_storage_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│ ├── oauth_state_storage_selftest.ts\n│ ├── rate_limit_selftest.ts\n│ └── release_audit.ts\n├── audits/\n│ ├── binance_mcp_probe.ts\n│ ├── binance_mcp_public_market_probe.ts\n│ ├── oauth_authorization_acceptance_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 └── SUBMISSION_PACKAGE.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.

RETURNING`, bounded busy retry and best-effort expiry pruning.\n- OAuth-state concurrency suite passed five consecutive executions after the fix; full 224-check release audit passed again at 2026-09-07T22:31:20Z.\n\n\n### Release validation\n\n- Core/live market suite: 101/101 PASS.\n- Source failure/malformed-response suite: 23/23 PASS.\n- OAuth flow suite: 34/34 PASS.\n- OAuth token/MCP suite: 25/25 PASS.\n- OAuth state storage suite: 6/6 PASS.\n- Rate-limit mutation: 35/35 expected transitions PASS.\n- Aggregate: **189 assertions + 35 mutation steps = 224 executed checks PASS**.\n- A test-harness race was discovered when global fetch mutation suites were statically imported; aggregate execution now imports mutation suites sequentially.\n\n### Submission readiness\n\n- Updated README, architecture, evidence and submission checklist to distinguish public Market Data from MCP connection authorization.\n- Current technical blockers are external proof gates: real supported-client MCP connection, final screen recording, GitHub mirror if used, X submission and Binance survey.\n\n## 2026-09-07 — PayAna Market Sentinel 1.0 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
