 "title": "Replace an outdated decision without losing history",
 "page_title": "How to replace an outdated decision without losing history with Encephalon",
 "summary": "Supersede an old record with a new one so agents see the current choice and the past.",
 "who": "A maintainer whose earlier decision no longer matches how the project works.",
 "problem": "Editing or deleting an old decision would erase history, while leaving it active would mislead agents.",
 "outcome": "A new active record replaces the old head, and the old record stays readable as superseded history.",
 "steps": [
  "Run `npx --no-install encephalon search --compact 'authentication tokens'` to find the current subject and active record.",
  "Run `npx --no-install encephalon add --id auth-tokens-v2 --kind decision --subject api.authentication --source agent --supersedes auth-tokens --data '{\"summary\":\"Use short-lived signed bearer tokens\"}' --text 'authentication tokens'` to add the replacement.",
  "Run `npx --no-install encephalon search --compact --include-superseded authentication` to confirm both records are visible with their status.",
  "Run `npx --no-install encephalon show --id auth-tokens --active-only` to confirm the old record is no longer returned as active."
 ],
 "agent_prompt": "In the repository <repo-path>, find the active decision for <subject>, then add a replacement record that supersedes it. Expected output: the add result and a compact search that includes superseded records. Verify that the old record ID is not returned by show with --active-only.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "A replacement must supersede every active head with the same kind and subject, so search the subject first.",
