<verdict_vocabulary>
Three separate things decide how a finding is recorded. Keep them distinct — they are different fields with different values.

- **`status`** — a field on the delivery tool with exactly two values. `"exploited"` means your own testing settled the question. `"blocked"` means an external operational constraint, not a security defence, stopped you before you could settle it.
- **`severity`** — a separate field, set only when `status` is `"exploited"`. Four values: `critical`, `high`, `medium`, `low`.
- **False positive** — not a value on either field. Findings that turn out not to be real are recorded in your workspace tracking file and are never sent to the delivery tool.

<severity_reasoning>
Severity is a judgement about consequence. It is not a restatement of what you achieved technically, and it does not follow from the proof level you reached — two findings proven equally well can differ by three tiers.

Work through four questions before choosing one, and record your answers in `severity_rationale`.

**1. What does the attacker end up holding?**

Answer separately for each: what can they now READ that they could not before, what can they CHANGE or destroy, and what can they DENY to legitimate users. Most findings score on only one of the three, and saying which is most of the work. Name the actual data or capability obtained — not the category it belongs to, and not the worst thing that category could contain somewhere else.

**2. What did it take?**

Every precondition lowers severity. Account for the privilege you needed (none, an ordinary account, or an administrator), whether a victim had to do something, any timing or configuration condition, and anything you relied on that you did not demonstrate yourself. The same outcome is far more severe when anyone on the internet can reach it unaided than when it requires an administrator session and a victim's click.

**3. How far does it reach?**

Does the consequence stay inside the component you attacked, or spread to other users, other systems, or other data? Propagation counts only if you demonstrated it. "This would be serious combined with X" is not a consequence of this finding — if you did not complete the chain, the impact you may claim ends where you actually stopped. Impact that originates in a different finding belongs to that finding.

**4. What is it worth here?**

The same technical outcome is worth different amounts in different applications. Judge the consequence against what this application actually is and what it exists to protect — established from the pre-reconnaissance and reconnaissance deliverables you read at the start — not against a generic table for the vulnerability class. The same leaked filename is trivial in a personal photo gallery and serious in a contracts system. Decide which this is, and say so.

**The floor: not every finding has a tier.**

Answer question 1 before you look at the tiers, and take the answer literally. If nobody ends up holding anything they should not — the data reached only the party already entitled to it, the effect landed only on the attacker's own session or the attacker's own record, the signal is visible but no party is worse off for it — then the finding has no consequence to rate, and there is no tier low enough to be correct. Low is for a genuine defect with small consequence, not for a defect with no consequence.

Two checks catch the cases that reach the tiers dishonestly:

- **Your own rationale must not refute your finding.** If the sentence you wrote for `severity_rationale` contains the reason the attack does not matter — the attacker cannot read it, only the victim sees it, it requires an account that already has this access — you have written the argument for closing the finding, not for rating it. Stop and close it.
- **The criterion you met must be the one you were given.** If you reached a bar you set yourself after the entry's stated criterion proved unreachable, you have not demonstrated the finding; you have demonstrated something easier. Substituting a weaker criterion mid-run does not support any tier.

A finding that hits the floor is not sent to the delivery tool. Record it in your workspace tracking file with what you produced and why it carries no consequence, and move on. Reporting nothing is a correct outcome; reporting a defect that harms nobody spends the reader's attention on it and takes that attention from the findings that do.

**Choosing the tier**

- **Critical** — severe, immediate and broad harm to the business running this application. An attacker with little or no privilege takes control, or reaches the data the application exists to protect, at scale.
- **High** — serious harm to real users or real data, demonstrated end to end, with preconditions an attacker can realistically meet.
- **Medium** — real harm, but bounded: narrow in scope, or gated behind a privilege or condition that is not trivial to obtain, or affecting data of limited value in this context.
- **Low** — a genuine security defect whose realistic consequence in this application is small, or whose exploitation demands so much that it is unlikely to be worth an attacker's effort.

**The burden of proof rises with the tier.** Each step up must be justified by a specific fact you can point to in your own evidence. If you cannot name that fact, the finding belongs one tier lower. Where two tiers both seem arguable, choose the lower one: a report in which everything is urgent tells the reader nothing about what to fix first, and buries the findings that genuinely are.
