What this preview is

A fixed synthetic demonstration of how a future decision-support product could communicate a potential deal and its limitations. It does not query a marketplace, private engine, subscriber archive, account, payment provider, or Telegram account.

No purchase contract

There is no price, checkout, trial, renewal, entitlement, paid channel, refund balance, or service-level commitment in this preview. Pressing a link cannot create a subscription. A future paid pilot needs separate reviewed commercial terms, support, cancellation, tax, refund, and delivery controls before it opens.

Telegram boundary

The test webhook can answer a small allowlisted command set only when its server-side fixture mode and Telegram webhook secret are configured and an operator attests that the bot is new, invoice-free, has dropped pending updates, and has its privacy URL wired. Telegram and Cambridge TCG's Vercel-hosted route process the bounded update needed to answer, including Telegram/user and private-chat identifiers and command text; Cambridge stores no application update, account link, entitlement, or payment record, while provider infrastructure logs and Telegram's own records can still exist. Read the detailed Telegram preview privacy notice. Any future digital purchase completed inside Telegram must use Telegram Stars and verified payment evidence; an external web rail is not smuggled into the bot.

Pre-checkout is rejected. If a payment or refund update reaches this non-payment preview anyway, the route returns a retryable non-success response instead of acknowledging, discarding, or pretending it can fulfil the provider receipt. Do not connect the preview to a bot with invoice or payment history.

The exact private-chat command allowlist is /demo, /terms, /privacy, /support, /paysupport. The deep-link command replies only to /start demo_prism_v1. Other text, commands, and start parameters receive no reply.

The signal's refusals

• No executable exit quote
• No listing reservation
• No profit guarantee
• No authenticity or condition verification
• No financial or tax advice
• No source rows or model parameters

A potential-deal label is not guaranteed arbitrage. Confidence is evidence quality, not profit probability. Liquidity may remain unknown. Availability, condition, authenticity, fees, tax, shipping, and time to sell can differ from any evidence later admitted by a live product.

Data rights stay upstream

Payment, transformation, secrecy, and channel access do not create permission to use or redistribute source data. No real evidence enters until a purpose-specific decision permitssubscriber_derived_signalfor that evidence bundle.
