Evidence index

evidence_index is an array of structured entries representing the URLs and external context the triage report cites. Use it to render reviewer-facing panels without parsing the free-text reason_summary.

Entry shape

Every entry has:

string

required

The cited URL.

string

required

One of traversed_link, external_mention, direct_link, or unknown.

string

When Tumban cited the entry by reference (link_3, external_mention_2, …), this field correlates the entry to the matching token inside reason_summary — use it to highlight the cited URL alongside the prose summary.

Type-specific fields:

traversed_link
external_mention
direct_link
unknown

Includes domain. The URL was followed from the profile page or matched via referrer cross-reference.

Includes platform_type and risk_level. The URL is a site elsewhere on the web that mentions the profile.platform_type is one of:

adult_content_site
cam_site
social_media
unknown

risk_level is HIGH, MEDIUM, or LOW — derived directly from platform_type (e.g. adult_content_site and cam_site are HIGH; unknown is MEDIUM; everything else is LOW). Treat it as a convenience field, not an independent signal.

Includes domain and category. The URL appears directly in the profile bio.category is a human-readable string drawn from a fixed set:

PROHIBITED (P0 Adult Content Platform)
PROHIBITED (P1 Gambling Platform)
Social Media (Neutral)
Link Aggregator (Review Links)
Personal/Unknown

Match on the leading PROHIBITED prefix if you want to lump P0 and P1 together.

Rare fallback. Includes a derived domain. The entry didn’t match any of the buckets above.

Example

"evidence_index": [
  {
    "ref": "link_2",
    "url": "https://prohibited-platform.example/username",
    "type": "traversed_link",
    "domain": "prohibited-platform.example"
  },
  {
    "ref": "external_mention_1",
    "url": "https://forum.example/posts/12345",
    "type": "external_mention",
    "platform_type": "adult_content_site",
    "risk_level": "HIGH"
  },
  {
    "url": "https://aggregator.example/username",
    "type": "direct_link",
    "domain": "aggregator.example",
    "category": "Link Aggregator (Review Links)"
  }
]

Empty array

evidence_index can be [] even on a flagged scan — Tumban may reach a decision from signals that don’t have a per-URL citation to surface. Treat an empty array as “no per-URL evidence to render”, not as a feature failure.
