The criteria, in detail
The five tests exist because the chat-app signal market is thick with assertions an outsider has no way to confirm. Three of them carry their own page, because they are the ones channels most often fail. The full five-test method is on the method page.
What the five tests are really sorting
Start with the evidence chain for the service you are actually considering: first-version message, edits and cancellations, subscriber receipt time, first tradable quote, and a complete count of outcomes. A Telegram channel can preserve that chain; a glossy platform can omit it. Neither format deserves a category-wide pass or fail.
The message audit tests what changed in the chat. The delivery test measures what a subscriber could receive. The provider directory then compares named products on evidence and use case.
Why these two columns decide most cases
For a published trade call, original-message integrity and a complete denominator answer different questions. A verified timestamp supports the covered bytes by its confirmed block time. The denominator tests whether all calls, including losing, edited and expired ones, remain in view. Neither tells you when a subscriber saw the post or what price was executable. Public pricing, grading rules and commercial incentives add useful context after those records are collected.
The three tests with their own page
Use the original five questions to organise the available record. This edition did not open paid channels or perform subscriber tests. Evidence states distinguish documented features, represented originals and unresolved populations. A timing question cannot replace complete history, label calibration, the selected offer or the relationship register.
Retained source trail: sealed before the outcome / auditable record / grades that are measured
Sealed before the outcome
Why a public timestamp is the one test a chat-app channel cannot wriggle around.
An auditable record
What a real track record contains, and what a pinned highlight reel leaves out.
Grades that are measured
How to investigate a frozen A-D definition without treating an unprovided calibration report as verified evidence.
Pricing and incentives are covered on the method page. Record the actual subscription terms and any affiliate relationship for the named channel; neither substitutes for a usable alert archive.
Use evidence states rather than invented pass totals
The five original questions remain: publication timing, complete history, label definition, actual commitment and incentives. Their role is to organise investigation, not assert that every provider was privately tested. A documented feature, a represented original, an unresolved sample and an inapplicable category deserve different states rather than a forced positive or negative score.
A fictional scanner review can document an alert feature while leaving Telegram forwarding unknown. A fictional room review can retain a complete message format while lacking the expected outcome population. Neither result justifies a universal rank. Current access and commercial relationships need their own source records; charging subscribers alone does not prove aligned incentives.
