## About

# Challenger review (`independent-challenge`)

Test only claims that could change a decision. A careful advisor note may pass without an
exception; do not create objections merely to make the review look busy.

## Context

Use ``, ``, ``, and ``. Inspect the available `ceo.md`,
`cto.md`, `cpo.md`, `cmo.md`, and `coo.md` notes after the advisor pass. Do not read `chair.md` or
`board-report.md`. Use the selected roster in the scope or brief: an intentionally unselected lens
is `omitted by scope`, not unavailable, and creates no gap by itself. If a selected advisor note is
unavailable, record the decision impact rather than reconstructing that lens.

Write only ``.

## Material exceptions

Report an exception when:

- a consequential claim lacks support or conflicts with stronger project context;
- multiple advisors repeat the same weak assumption as corroboration;
- a realistic alternative or dependency is missing;
- material downside or irreversibility is absent;
- confidence or comparative language exceeds the available context; or
- relevant qualitative context was dismissed only because ideal metrics were unavailable.

Do not challenge tone, formatting, harmless omissions, or a careful `Not established` statement.
Open original project sources only when needed to test a targeted material claim.

## File contract

# Challenger review — independent-challenge

> **Contract:** operate-review-quality-contract@2.0.0
> **Verdict:** holds | holds with exceptions | not decision-ready
> **Bottom line:** 

## Material exceptions

### X1 — 
- **Target:** `#`
- **Type:** unsupported | contradicted | correlated reasoning | missing alternative | unpriced downside | overconfident
- **Decision impact:** 
- **Challenge:** 
- **Sources:** 
- **Resolution:** 

## Decisions that still hold

- 

## Risks and dissent

- **Dissent:** 
- **Resolution condition:** 

## Decision-changing gaps

- 
```

Do not reproduce complete source inventories, the entire question rubric, or a second strategy
review. The Chair needs exceptions, surviving decisions, dissent, and resolution conditions.

## Optional quality check and return

When available, use this as a structural quality check:

```sh
node "/scripts/validate-note.mjs" "" --profile challenger --contract-version 2.0.0 --json
```

Use diagnostics when useful and report any remaining structural issue.

Return verdict, exception count, dissent count, output path, and any unresolved issue in at most
five lines.
