# Checkpoint the active task

Update `.claude/work/active.md`. If it does not exist, create it from the template only when a substantial
task is actually active.

Verify the current conversation's claims against:

- `git status --short`
- `git diff --stat` and the relevant diff
- files and symbols referenced by the task packet
- exact observed command output for verification claims

Preserve the goal, authority surface, invariants, decisions with reasons, exact evidence, changed files,
completed work, failed approaches, exact test outcomes, discovered follow-ups, remaining work, and one
next action. Remove superseded hypotheses, raw logs, conversational narration, completed plans, and
machine-specific paths.

Reconcile every discovered soundness defect: it must be fixed in scope, linked to an existing or newly
created issue, or marked `authorization required` with an explicit user request. Do not mark the task
complete while such a finding exists only in chat, review output, or agent memory.

Do not claim a test passed because it was planned, started, or passed in an earlier tree state. Do not use
the checkpoint to introduce a new design decision or expand scope silently.
