What Is an Evidence Pack?
Category: Transmission chainsChinese: 证据包
Short definition
An evidence pack is the per-hop bundle a chain note exposes to readers — verbatim quote, source link and category, magnitude with basis and track, supports-yes and supports-no lists, entailment verdicts and an as-of date — so any hop can be audited without leaving the page.
What it means
A chain is only as trustworthy as its least-inspected hop, and readers do not inspect what is inconvenient to inspect. The evidence pack is the answer: every hop opens into one panel that holds the whole audit trail. Nothing in it is new information — it is the material the hop was built from — but gathering it in one place is what turns "trust me" into "check me".
The pack has a fixed shape. The quote, verbatim and in the source's language. The source, with a link and a category (filing, company statement, first-party documentation, press report). The magnitude, with the basis it was computed on and its track. Two brief lists — what this evidence supports, and what it does not. The entailment verdicts for relationship and magnitude, with reasons. The as-of date. A hop whose pack is missing a required element is not publishable.
The supports-no list is the part that distinguishes the pack from a citation. A citation says "this is where I got it"; supports-no says "here is what you might assume this proves, and it does not." It is where the author writes down the limits of the evidence before a reader has to find them, and it is the single most useful line for a learner deciding how much weight to put on a hop.
What a complete evidence pack contains
Open any hop; the pack should show all of these:
- A quote that can be searched for verbatim in the linked source.
- A source category, so a filing is not mistaken for a press summary.
- A magnitude, its unit, its basis line and its track colour.
- At least one supports-yes line and, for estimated hops, at least one supports-no line.
- Relationship and magnitude verdicts, each with a reason that quotes the passage.
- An as-of date drawn from the source, not from the note.
Using an evidence pack as a reader
The pack is built for a five-minute audit; this is the audit:
- 1.Open the source and find the quote; if you cannot, stop trusting the hop.
- 2.Check the magnitude against the quote — is the number there, or are both numbers behind it there?
- 3.Read supports-no before supports-yes; it tells you what the author already knows the hop cannot carry.
- 4.Compare the as-of date with the event date; decide whether this was knowable when the event happened.
- 5.Write one sentence on whether you would weight this hop more or less than the author did, and why — that sentence is the learning.
Frequently asked questions
Why show all of this to a reader who only wants the summary?
Because the summary is not the product; the checkable chain is. A reader who never opens a pack loses nothing, and a reader who does can catch an error the author missed. Keeping the packs visible is how the method stays honest under scrutiny.
How is an evidence pack different from a footnote?
A footnote locates a source. A pack locates the source, quotes the exact passage, states the magnitude's basis and track, records what the evidence does and does not support, gives the entailment verdicts and dates the fact. It is a footnote that has been made auditable.
What if the quote is in a language I do not read?
The quote stays in the source's language on purpose — translating it would put a step between the reader and the evidence. The evidence note beside it describes what the passage establishes; the verbatim text is there so anyone who does read the language can confirm the description.
