# Confidence

> How confident Tumban is in a recommendation.

Every triage report includes a `confidence` field with one of three
values:

| Value    | What it means                                                                                                                   |
| -------- | ------------------------------------------------------------------------------------------------------------------------------- |
| `high`   | Tumban has strong, corroborated evidence backing the recommendation. Act on it without further qualification.                   |
| `medium` | Tumban has solid signal but less corroboration. Useful, but a manual reviewer may want to spot-check on edge cases.             |
| `low`    | Tumban surfaced something worth looking at, but the signal is thin or borderline. Treat as a review-worthy lead, not a verdict. |

A `no_flags` recommendation does **not** guarantee `high` confidence.
A profile that is clear except for a single thin signal can come back
`no_flags` with `medium` or `low` confidence, and a scan that hit an
infrastructure fallback (see [`ANALYSIS_ERROR`](/reference/reason-codes),
a neutral score) can return `no_flags` at `low` confidence. Only a
profile with no signal at all is guaranteed `high`. Read `confidence`
directly — never infer it from the recommendation tier.

## When to use it

Use `confidence` to weight review priority **within** a recommendation
tier. A `review_high` with `confidence: "high"` is worth processing
before a `review_high` with `confidence: "low"`. Within a queue sorted
by `risk_score`, breaking ties on `confidence` is a reasonable second
key.

How Tumban arrives at each level is not part of the public contract —
the exact triggers may change as detection is tuned. Treat `confidence`
as an interpretation of the same evidence summarised by `reason_codes`
and `evidence_index`, not as an independent signal.
