Provable-first exposure work, run on the FAFO eight-step order.

Register a subject’s selectors, run the eight-step order, and produce a provenance-logged, chain-of-custody-clean evidence trail. Provable-first OSINT: every hit cited, timestamped, chain-of-custody clean.

Case label

FAFO eight-step order

The methodology every case runs on.

1
Scope & authorization
Confirm lawful basis and the bounds of the engagement before any collection.
2
Define subject surface
Register the selectors — emails, names, handles, domains, BINs.
3
Passive collection
Ingest from lawful feeds only. No scraping into legal gray zones.
4
Match against surface only
Confirm exposure of the registered selectors; discard everything else.
5
Provenance & confidence
Attach source + timestamp + confidence to every corroborated hit.
6
Pivot
Use confirmed hits to register adjacent selectors, then re-run — never broaden blindly.
7
Chain-of-custody packaging
Seal findings under a SHA-256 integrity receipt for a clean handoff.
8
Referral / handoff
If a walled-off class appears, route to NCMEC / IC3. Perimeter never handles that content.
