 "title": "Detect any edited forecast in a ledger file",
 "page_title": "How to detect any edited forecast in a ledger file with Brier",
 "summary": "Run the verify command to find the exact line where a sealed probability was changed.",
 "who": "Someone who received a forecast ledger from another person or team and needs to confirm no answer was edited after it was sealed.",
 "problem": "A forecast file can be quietly altered after the fact, which makes past accuracy claims impossible to trust.",
 "outcome": "A verification result confirming the chain is intact, or naming the first line where the hashes stop matching.",
 "steps": [
  "Place the ledger file in the Brier project folder.",
  "Run `brier ledger --verify`.",
  "If it reports a break, note the line number it names.",
  "Compare that line against the original source you trust before drawing any conclusion."
 ],
 "agent_prompt": "In the Noisyxl/brier repo, run `brier ledger --verify` on the ledger file at <path-to-ledger>. Report whether the chain is intact, and if not, the exact line the command names. Verify the output text before stating a result.",
 "agents": [
  "any"
 ],
 "difficulty": "Beginner",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "The hash chain proves the file was not edited, but it does not by itself prove when a forecast was sealed, which is what anchoring is for.",
 "category": "Research",
 "tags": [
  "Research"
 ],
 "lang": "html",
 "requirements": [
  "A terminal with Node.js and npx, since the README's commands run through npx",
  "An API key in a .env file, only if you want your own models on the board",
  "A wallet you control, only if you want to anchor the head hash on Robinhood Chain"
