Specialities organised by the technical question and the object under analysis.

Installations, energy, power quality, machinery, equipment, electrical or electronic failures and automation are examined according to the technical question and the available records.

Software, firmware, embedded systems, IoT, integrations, logs and system behaviour require a joint reading of architecture, versions, configuration and operating context.

Physical documents, substrates, alterations, erasures, compositions, handwritten signatures and comparison standards are analysed using methods appropriate to each object.

PDFs, metadata, document structure, electronic contracts, certificates, signature platforms and authentication journeys are assessed without treating an isolated indicator as automatic proof.

Logs, files, timelines, system records, electronic operations, hashes, preservation and chain of custody are correlated according to origin, integrity and availability.

On-chain transactions, smart contracts, wallets as technical identifiers, tokens and off-chain sources may form part of the analysis. A wallet does not by itself identify a person, establish authorship or enable promises of asset recovery.
