Methodology white paper.

[FOUNDER-EDIT] The team's published methodology — extended from the how-it-works page with full source register and failure-mode analysis. This is the document our auditors and pilot customers reference. The methodology in effect at the time of any record's issuance is captured by version reference on the record itself.

What an attestation means

The lawyer's signature on a trust letter attests that the diligence steps described were performed by Trust Letter Service personnel using the methodology published here as of the issue date, and that the supporting evidence (source URLs, retrieval timestamps, content hashes) is on file with the team. The signature is not a legal opinion on the subject charity's status under any tax, regulatory, or other regime, and it is not a recommendation that any grant be made. Use of the service does not create an attorney-client relationship.

Sources by jurisdiction

[FOUNDER-EDIT] Per-jurisdiction listing of the primary register, sanctions feeds, financial-disclosure source, governance-disclosure source, and any known gaps.

Confidence, refusal, and rescission

[FOUNDER-EDIT] When we decline to issue a record (sanctions match, primary register not reachable, charity cannot be matched), refund, escalate to manual review, or rescind a previously-issued record.

LLM-assisted extraction

[FOUNDER-EDIT] Where we use LLM-assisted extraction (jurisdictions and data categories), the model and version, the human-review threshold, and the audit trail captured for every call. LLM-extracted findings are flagged in the record alongside the source URL, and any check below a configured confidence threshold is mandatorily reviewed by a human before signing.
