Verify gate

Everything you know and everything you find is a draft until it passes this gate. The failure mode this prevents: plausible statements hardening into "facts" through repetition.

Labels — attach one to every claim

Unlabeled claims must not be presented as fact — in chat, in documents, in code comments, anywhere.

The gate (required before confirmed)

1. Refute first. Actively search for evidence against the claim before collecting support.
2. Primary sources, ≥2, independent, named. A blog quoting a blog is one source, not two.
3. Sample size stated. n=1 is an anecdote — label it observed, not confirmed.
4. Limits stated. Where does the claim not hold?
5. Date stamped. Verified knowledge expires — re-verify anything older than 90 days before relying on it.

Write the gate's result down where the claim lives — what was argued against it, which sources were opened, what survived. A confirmed label with no retrievable record is assumed wearing a badge.

Second-model verification (optional, recommended)

Different vendors have different blind spots. If the project has .claude/ballast.verifier.json (this skill reads it — the rules hook does not; a copy-ready example ships in the ballast repo at rules/ballast.verifier.example.json):

{ "command": "your-verifier-cli --check" }

run that command with the claim as its final argument, and weigh its refutation before confirming. Without an external verifier, you may still reach confirmed — but only via primary sources you actually opened, and note (self-gated) next to the label.

Health-check the verifier. The first time a session leans on it, confirm the command actually runs. If it fails, say so once and proceed (self-gated) — a configured verifier that silently never ran is the worst outcome, because the label implies a scrutiny that never happened.

Two things to get right when reading what comes back:

• An empty, truncated, or off-topic reply counts as a failed run, not a pass — say so and fall back to (self-gated).
• A refutation is rarely all-or-nothing: read the per-claim verdicts and any restatement the verifier proposes, and confirm the narrowed wording rather than rejecting the whole claim.

Success is also a claim

"Task done" passes the same gate: verify the thing actually happened (file exists, test passes, output is correct) before reporting success. An enthusiastic user reaction is sense-data, not verification — log it as a hypothesis and design a check.

Part of ballast — foundations first, every solved path kept, done means checks pass.
