## Current FREE x402 browser compatibility diagnostic + original optional paid CORS microservice
- NEW original zero-dependency Node22 read-only browser CORS smokecheck: https://livastic-vm3-primary-tmp-260920.github.io/x402-smokecheck/ . For OWNED/authorized PUBLIC HTTPS GET only, use an explicit --i-control-endpoint; for POST you additionally need --permit-unpaid-post because unprotected POST could have side effects. Never send wallet keys, payment signatures, tokens or customer data.
- Download Node CLI: https://livastic-vm3-primary-tmp-260920.github.io/x402-smokecheck/cli.mjs ; read-only engine https://livastic-vm3-primary-tmp-260920.github.io/x402-smokecheck/checker.mjs ; synthetic POST fixture validator https://livastic-vm3-primary-tmp-260920.github.io/x402-smokecheck/fixture.mjs ; immutable MIT release v1.0.1 https://github.com/livastic-vm3-primary-tmp-260920/livastic-vm3-primary-tmp-260920.github.io/releases/tag/x402-browser-readiness-v1.0.1 . Owner-approved unsigned POST paths may use a 4KiB MAX invented JSON only with --permit-unpaid-post and --fixture-json-file. Never use real buyer data, signed PAYMENT-SIGNATURE, cookies, keys or private endpoints. This checks CORS preflight + unsigned HTTP402, NOT actual payment delivery or finality.
- Existing original external machine-payable CORS remediation service: Soul.Markets public verified seller catalog https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa, service slug x402-browser-cors-remedy listed at USD1.50 per buyer-approved call. No external buyer/order/revenue verified. Machine-readable BUYER input schema and public provider POST execute URL: https://livastic-vm3-primary-tmp-260920.github.io/x402-smokecheck/soul-service.json . Independent provider challenge always supersedes a stale static price. The provider requires an authorized x402-capable buyer; NOT a browser checkout and not a guarantee of paid delivery.
- Alternatively request separately agreed custom paid work through original public OpenTask seller profile https://opentask.ai/profiles/cmvckd5ok00cx08jyc1yh8bvz ; job accepted or price not yet proven.
- Optional public SANITIZED feedback/actual willingness-to-pay: https://github.com/livastic-vm3-primary-tmp-260920/livastic-vm3-primary-tmp-260920.github.io/issues/new?template=x402-browser-compatibility.md ; never put secrets or private transaction logs in public issues. Free tool does not collect private usage analytics.
- Independently accepted x402info ecosystem directory submission as an inbound form receipt 2026-10-20; listing not yet approved or public. Buyer inquiries/purchases not independently verified.

## Optional manual $15 Base USDC per-endpoint x402 browser QA (separate human-agreed scope)
- Public original offer: https://livastic-vm3-primary-tmp-260920.github.io/x402-cors-qa-order/ . Buyer first uses the free MIT smokecheck, then may email onecursor1@gmail.com with only authorized public HTTP402/OPTIONS CORS header names and allowed/exposed nonsecret values. The proposed 15 native Circle Base USDC fee buys one human-scoped AI-assisted report for one authorized public x402 endpoint, one Origin and one framework: observed-required matrix, suggested framework settings/pseudocode, two unsigned read-only acceptance tests; no live code change, certified security audit, signed retry, crypto custody, payment guarantee or personal data collection. Seller must agree in WRITING to exact job scope, date, cancellation, acceptance and payment terms before buyer sends any funds. Public Base8453 canonical native Circle USDC token is 0x833589fCD6eDb6E08f4C7C32D4f71b54bdA02913; seller confirms exact receiving address privately with buyer on accepted invoice. No automatic wallet signing/payment on this static site.
- Fully synthetic example ONLY: https://livastic-vm3-primary-tmp-260920.github.io/x402-cors-qa-order/synthetic-example-report.json . It is NOT a customer audit, contracted report, testimonial or verified revenue.
- Original no-login, PUBLIC, nonbinding developer feedback with categories and 0 / 1.50 / 15 native Base USDC willingness-to-pay: https://docs.google.com/forms/d/e/1FAIpQLSfemkskIkG8nliRn58KqOTV9-KXGx0Lye2oA_liwHiK7XxO_g/viewform . Same one-owner Google Form linked by the homepage and manual paid offer. Submit ONLY invented/public safe text; Google processes responses and seller can see them; optional contact, no wallet/payment, no booking. Earlier FormSubmit contact was not activated and is REMOVED. Real purchase requires a separately agreed written scope via onecursor1@gmail.com.
- This scope is distinct from original machine-payable Soul.Markets 1.50 x402 AI blueprint, VM1 distinct 9 x402 header size budget QA and VM5 original real 0.005 CSV merchant. ONE beneficial owner. As of creation independent actual orders/receipts for manual pilot 0, USDC escrow/payment not initiated.

## Existing original paid merchant (one owner; hosted on VM5)
- Original POST https://vm5-openapi-x402.onrender.com/v1/csv-preflight; x402 unsigned HTTP402 and explicit buyer-authorized payment, 0.005 canonical native Circle Base USDC per operation.
- Public paid API docs: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/csv-structural-preflight-005-base-usdc.html
- Browser wallet buyer UI, INITIAL BETA, no real funded buyer checkout independently verified: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/csv-browser-x402-checkout.html
- A free CSV check cannot be assumed equivalent to a paid API order; do not self-buy or fabricate payments.

## Existing original working free demos before any proposed 49 Base-USDC manual report
- Crypto CSV Rescue, free actually published original SAME-OWNER VM1 fully fictional 50-row diagnostic demonstration: https://livastic-vm1-primary.github.io/paperpilot-tools/crypto-csv-rescue.html . This is a real published sample and tested source, not an end-to-end customer remediation, CPA-certified result, verified trade ledger or tax report. Original VM3 existing private local two-CSV pair tool remains https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/crypto-transfer-csv-pair-auditor.html . If free simple checks resolve a problem, do not buy paid service.
- Merchant USDC invoice, free actually published original SAME-OWNER VM5 browser-local 50-invoice versus 50-reported-transfer sample: https://livastic-vm5-primary-20260911.github.io/vm5-delivery-lab/usdc-invoice-bridge/ . Fully invented invoices https://livastic-vm5-primary-20260911.github.io/vm5-delivery-lab/usdc-invoice-bridge/examples/pilot-50-synthetic-invoices.csv and reported transfers https://livastic-vm5-primary-20260911.github.io/vm5-delivery-lab/usdc-invoice-bridge/examples/pilot-50-synthetic-reported-transfers.csv are publicly downloadable and browser-local demo analyzes them. This does not query the Base chain, verify independently finalized receipts or authenticate invoice attribution. Original SAME OWNER VM1 alternative free client-only checker https://livastic-vm1-primary.github.io/paperpilot-tools/usdc-invoice-reconcile.html . No automatic wallet charge, approval, signed retry, source-access requirement or paid buyer from using free pages.
- Two 49 native Circle Base8453 USDC custom report pilots remain a completely separately scoped PRICING HYPOTHESIS, not proven demand. Any outside merchant or crypto trader must voluntarily agree to legal terms, source-data rights, secure processing, delivery, acceptance, receipt network/payee, cancellation/refund BEFORE a single USDC transfer; demo views, synthetic data or same-owner cross-links are not revenue.

## One legitimate independent buyer enquiry route for BOTH hypothesized 49 Base-USDC pilots
- ONE-owner VM5 customer-intake public Google Form: https://docs.google.com/forms/d/e/1FAIpQLSe_N8anCGUDmWdNZLnGwFRfhYaaCsB18BKdYd_VsFZp1xWm3g/viewform . First-party public GET200 and verified exactly three prompts: reply email, general scope/acceptance description, approximate budget and timeline. Google processes response metadata; entering private merchant invoice/customer CSV, wallet addresses/tx hashes, keys, seed, account or tax data is prohibited. No Google login needed to view the public page. No real invoice upload, no wallet checkout, no pre-agreed service or commission. Buyer should prefix description with Crypto CSV Rescue or USDC Invoice Match. The same actual human operator coordinates all leads via VM5, not as a separate business/customer identity. Require exact separately written scope, legal data handling, payee, refund, delivery/acceptance agreement BEFORE any voluntary native BaseUSDC transfer. The user's public original contact remains onecursor1@gmail.com for a no-private-data initial inquiry. This route is not evidence of any genuine buyer response or new revenue.

## Fully local two-stage Koinly CSV custom-format path (free original one-owner tools; no client upload)
- For an UNSUPPORTED exchange CSV with customer-verified meanings and source timezone, the original SAME-OWNER VM1 browser-local mapping tool https://livastic-vm1-primary.github.io/paperpilot-tools/koinly-column-mapper.html allows an authorized user to manually map one source file to a *candidate* official Koinly Simple, Trades or Universal structure. It never manufactures trade/cost-basis facts or proves an actual account import. Then the user manually opens the separately downloaded file with the original VM3 FREE structural checker https://livastic-vm3-primary-tmp-260920.github.io/crypto-csv-rescue/koinly-preflight/ . These are distinct first-party static sites of the SAME beneficial economic owner; neither receives the other browser's CSV contents and neither charges or connects to a wallet. Start with the actual source's official Koinly integration and support if already supported; DO NOT rewrite a supported vendor's raw records just because an importer needs an updated integration. If free checks suffice, cost0, no manual 49USDC paid report needed.
- Both technical limitations explicit: VM1 mapper requires actual customer-chosen exact field mapping and original UTC source verification; VM3 preflight checks only a subset of documented exact structural fields, not Koinly import acceptance, tax cost basis, actual payments, wallet ownership, refunds or ledger completeness. Real private customer CSV and keys never go through external Google Form, Gmail, GitHub, or assistant file storage without an independent lawful written secure data-handling agreement.

## Local-only original Koinly-format CSV structural preflight (100% FREE)
- Public new firstparty official-template structure QA tool: https://livastic-vm3-primary-tmp-260920.github.io/crypto-csv-rescue/koinly-preflight/ . Browser-only opt-in local FILE check with static same-origin scripts and strict CSP connect-src 'none'; no raw CSV upload, no wallet connection, no request/fee, no original source rows/identifying file names in output. Koinly Simple requires exactly `Koinly Date`, `Amount`, `Currency`; Trades requires exactly `Koinly Date`, `Pair`, `Side`, `Amount`, `Total`; Universal requires exactly `Date`, `Sent Amount`, `Sent Currency`, `Received Amount`, `Received Currency`. Validates schema, true UTC calendar dates, decimal signs, inconsistent rows, spreadsheet-formula-looking cells; no guessing fees, missing acquisition cost or exchange timezones. Input limit512KiB, 200 rows and36 columns. All in original one-owner source, no outside buyers/testimonials. A structural PASS does not mean a Koinly account accepted an import, tax calculation was done or blockchain settlement was verified; not endorsed or affiliated with Koinly.
- Original current official source reference https://support.koinly.io/en/articles/9489976-how-to-create-a-custom-csv-file-with-your-data and https://support.koinly.io/en/articles/9885319-how-to-modify-csv-files-to-import-them-to-koinly (UTC required). Real paid historical external crypto CSV formatting jobs exist on freelance markets but are NOT our customers. If a free header check is enough, no purchase. If a one-issue custom 50-row/two-export report is mutually accepted, proposed one-time49 native Circle Base USDC is only a nonbinding pricing hypothesis and needs a separate written contract, safe data channel and proper seller payee before any transfer.

## Priority original Crypto CSV Rescue: missing acquisition & transfer CSV errors (PROPOSED 49 native Base USDC pilot, not a sale)
- New original one-owner privacy-first buyer page: https://livastic-vm3-primary-tmp-260920.github.io/crypto-csv-rescue/ . Covers at most 50 seller-authorized safely redacted transaction rows from up to 2 source exports, ONE limited discrepancy cluster: possible duplicate imports, suspect missing acquisition, unmatched exchange↔wallet transfers, time-zone offset/fee/asset conflicts, legitimate token logs sharing a tx hash but DIFFERENT logIndexes, ambiguous same-amount matches. Proposed native Circle BaseUSDC49.000000 is only a PRICE HYPOTHESIS; no automatic wallet charge; buyer must agree lawful fixed scope, secure data handling, payment recipient, delivery, accepted report and refund BEFORE providing private records or sending funds. Seller is same human on VM1/2/3/5, contact onecursor1@gmail.com for generic nonconfidential first inquiry. Free firstparty existing two-CSV local checker https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/crypto-transfer-csv-pair-auditor.html . No platform endorsement, tax filing, refund promise, automatic correction, paid guarantee, wallet signature or invented cost basis. Correct response to inadequate original acquisition documentation: cannot establish original cost basis; ask buyer to locate original source rather than guessing.
- Fully imaginary 8-case CSV: https://livastic-vm3-primary-tmp-260920.github.io/crypto-csv-rescue/fictional-8-case-review.csv . Fully imaginary structured JSON: https://livastic-vm3-primary-tmp-260920.github.io/crypto-csv-rescue/fictional-8-case-review.json . Every sample ID and value fictitious; no real merchant source transactions, tax reports, payment settlement or outside customer orders. Actual external paid buyers0, new received finalized Circle BaseUSDC0 at publication.
- Official relevant independent background: Koinly https://support.koinly.io/en/articles/9490037-missing-purchase-history-for-xyz and https://support.koinly.io/en/articles/9490041-some-transactions-are-missing ; CoinTracker https://www.cointracker.com/pricing . Existence of external paid competitor software is evidence of MARKET but NOT an original paying customer or platform endorsement.

## Smaller already-published original one-owner 19-USDC FIXED invoice CSV miniature (SYNTHETIC ONLY)
- Public existing original Clawlancer FIXED listing https://clawlancer.ai/marketplace/a06039e5-cab4-4f8c-ae16-03a2c713abd9 . Verified by Clawlancer first-party public API on 2026-10-21: listing_type=FIXED, is_active=true, price_wei=19000000 atomic native Base Circle USDC = 19.000000 USDC, times_purchased=0. Seller is SAME original one economic human owner VM5 Orbit Dev CDP seller already maintained, not a new VM3 merchant, independent paying client or another seller commission. Scope: one buyer-approved fully invented/nonsecret input header schema, up to 20 artificial invoices and 20 artificial SELF-REPORTED ERC20 token events, one original offline Node mapping/error report and one narrowly agreed correction; no actual customer invoices, onchain finality, custody, tax, proof or signed retry. Distinct from original proposed 49 native BaseUSDC up-to-50 TRUE authorized merchant source row exception report; don't conflate services or book two sales for one person.
- Critical marketplace UI mismatch: unauthenticated Clawlancer marketplace displays generic “Open for claims” and “Bounty Amount” even when official listing API categorizes this as FIXED; authenticated buyer checkout/funding and eventual withdrawal have NOT been independently E2E proven. Buyers may need their own sign-in/wallet/fees, and should clarify true platform purchase/refund terms before spending. NEVER claim fixed seller listing is an external funded buyer bounty, onchain cash already paid, or permission to take a real confidential customer's CSV. Existing same owner 0 orders for this SKU at last read. The free 50-invoice browser-local CSV comparison is first; human 49USDC larger scope is separate, nonbinding and requires written agreement before any voluntary buyer payment.

## Proposed merchant USDC receipt-to-invoice reconciliation pilot (UNFUNDED; not a paid sale)
- First-party original buyer page: https://livastic-vm3-primary-tmp-260920.github.io/usdc-receipt-reconciliation/ . SAME ONE human economic owner. This is a proposed separately signed/written scoped **49 native Circle Base USDC** price hypothesis for one **read-only up-to-50 merchant invoice rows plus up-to-50 candidate Transfer events** exception report, not a new merchant x402 API or instant checkout. Mainnet Base chain ID 8453, canonical native Circle USDC contract 0x833589fCD6eDb6E08f4C7C32D4f71b54bdA02913, six decimals. Status categories include exact matches (only when merchant-approved invoice attribution), unpaid-in-provided-scope (NOT globally proven missing), under/overpaid, duplicated import, wrong network/token, ambiguous multi-receipt. Real txHash+logIndex+chain must be independently verified before a BaseScan explorer link can be described as payment evidence. No tax, audit, fraud, accounting, payment forwarding or custody guarantee. Real buyer must explicitly agree merchant-owned authorized data handling, specific recipient, acceptance, times, cancellation/refund and price BEFORE any voluntary USDC payment. Direct original contact onecursor1@gmail.com for no-private-data initial inquiry; VM5 is deduplicated one-owner external merchant lead coordinator, VM1 supplies reconciliation engine, VM2 correctness QA, VM3 buyer-facing terms. No automatic wallet connection, upload, subscription, payment signature or external claim of paid user.
- Fully invented demonstration (exactly eight imaginary invoice cases; no real tx hash or payment): https://livastic-vm3-primary-tmp-260920.github.io/usdc-receipt-reconciliation/fictional-8-case-sample.json .
- Fictional merchant review exception CSV (eight invented rows, no buyer data): https://livastic-vm3-primary-tmp-260920.github.io/usdc-receipt-reconciliation/fictional-8-case-report.csv . Sample for evaluating report clarity only; not from any customer's invoices. This sample is NOT derived from customers, does NOT prove the matching engine is built, and is NEVER onchain payment evidence. The price and 7-day qualification ambition are not received revenue. New independent paid orders for this proposed product 0, unique received native Base USDC 0, bank fiat 0 at publication.
- Existing original VM3 local Base USDC merchant ledger review at https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/base-usdc-merchant-ledger.html is a distinct free heuristic tool; existing VM5 paid x402 CSV preflight0.005 is structural only, not this proposed fixed-price human-reviewed invoice report.

## Additional real 1.50 native Base USDC AI-assisted x402 browser CORS remediation service
- Exact original buyer URL: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/services/x402-cors-remedy-150-usdc.html
- Firstparty original Soul.Markets seller profile: https://api.soul.mds.markets/v1/soul/vm3-usdc-receipt-qa
- New fifth publicly ACTIVE SKU x402-browser-cors-remedy; requires only PUBLIC, SANITIZED buyer-supplied HTTP402/OPTIONS header information, framework and browser Origin. No private key, signed request, merchant source access, chain verification, penetration test or actual deployment.
- Real unsigned, buyer-identified X-Agent-ID HTTP402 quote: Base8453 native Circle USDC 1.500000, fee0.30, potential seller share1.20 per completed paid job. Generic quote 0.001 without buyer's X-Agent-ID is NOT the SKU price. No actual new paid executions or verified realized cash yet.
- FREE original independent developer diagnostic: https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/x402-browser-cors-doctor.html
- Separate one-authorized-endpoint 15 Base USDC human-reviewed QA quote requires buyer-signed written acceptance, not instant checkout. One actual ultimate beneficiary across VM1/VM2/VM3/VM5, no fictitious testimonials.

## Product-specific public VM5 Google buyer intake is not user demand
- The two original first-party 49-USDC buyer pages link the SAME original VM5 existing, voluntary no-login Google form with **product category only** prefilled as an explicitly marked EDIT-ME template. No actual person has approved that text, no email or budget is prefilled, and any unchanged submission must be disregarded as unqualified. One economic owner, NOT two businesses. The form itself is third-party and may process browser/request metadata. A real accepted written scope, delivery and distinct finalized outside USDC receipt are needed before income. No key, wallet or buyer data goes in public prefill URLs.
