Two axes, not one. Every Unmai entry carries both a confidence level and a source-tier composition. This is how the discipline is audited from outside.
Confidence — Three Levels
Modelled on the Mnemonic / Syrian Archive practice. Fewer levels, clearer thresholds.
Verified
Two or more independent sources from at least two different tiers, plus a preserved artefact with a recorded hash. Geolocation and chronolocation confirmed where applicable.
Probable
Two independent sources, or one Tier A source with strong contextual corroboration. Artefact preserved. Geolocation or chronolocation partially confirmed.
Possible
Single credible source, or multiple sources without independence. Logged so a future signal can connect — never published as a finding on its own.
Source Taxonomy — Four Tiers
A Verified entry must draw on at least two different tiers. Tier D never stands alone.
A
Accredited bodies
UN OHCHR, UN Panel of Experts, ICRC, ICG, ICJ filings, recognised international tribunals.
Tamil-language local press, named community reporters, recognised diaspora outlets. Treated as leads requiring Tier A/B corroboration.
D
Open social signals
Public posts, videos, images from named accounts. Useful for geolocation and pattern-spotting. Never sufficient alone.
Response Windows (SLA)
Within 1 hour
Triage: is this in scope, is the source live, is the artefact captured and hashed?
Within 24 hours
Two-person review for Probable / Verified candidates. Possible signals logged to the pattern table.
Within 7 days
Cross-link with prior signals. Update the pattern view. If a Tier A body has published, defer to them and cite.
Always
If safety concerns exist for sources, named regions, or witnesses — we hold. There is no SLA on harm.
Redaction Defaults
·Names of survivors, witnesses, family members — never published.
·Names of alleged perpetrators — never published. That is the work of courts and accredited bodies.
·Precise locations that could identify a household — generalised to district level.
·Children's identities — full redaction, no exceptions.
·Operational security details for active workers — never published.
UK Online Safety Act Posture
Unmai operates from the United Kingdom. The Online Safety Act 2023, and Ofcom's illegal-content codes (live since March 2025), apply to any UK service that lets users share content with each other.
Unmai is therefore designed, deliberately, not to be a user-content service:
· No public body field for survivor testimony.
· No public file upload.
· No publication of third-party content under a user's name.
· No DMs, no comments, no forum.
Signals come from the open web — captured, hashed and reviewed by named investigators. Direct survivor intake is routed to bodies built for it: OHCHR, ITJP, PEARL, Mnemonic, and UK emergency services.
The HRDAG Humility Line
The Human Rights Data Analysis Group is explicit: when underlying datasets are gathered by adversarial parties, the assumptions behind multiple-systems estimation break and counts mislead. Unmai therefore does not publish casualty totals, victim counts or aggregate incident numbers. Counting is the work of accredited bodies — OHCHR, ITJP, PEARL, HRDAG. We cite them. We do not duplicate them.
