Content assembly (BuildContent) is separate from PDF drawing (Render), so the actual business logic — what goes into the evidence dossier, in what form, with which mandatory fields — is unit-testable without parsing PDF bytes. BuildContent refuses to produce a dossier missing its evidentiary fields (timestamp token, asset/metadata hash, platform) rather than emitting one with silently empty proof sections. Every dossier carries the "this is not legal advice" disclaimer required by CLAUDE.md's guardrails. Uses github.com/go-pdf/fpdf (actively maintained fork of jung-kurt/ gofpdf, no dependencies beyond the Go stdlib) for rendering. Its core fonts use cp1252 internally, so a small cp1252.map (copied from the fpdf module, embedded via go:embed) drives UnicodeTranslator — German umlauts render correctly without needing an external font file at runtime, keeping Deklarix a single binary. Verified visually with pdftotext/pdfinfo against a generated sample. Tests build a real, structurally valid RFC-3161 token offline (a throwaway self-signed cert + timestamp.Timestamp.CreateResponse), so BuildContent/Render/Generate are fully tested without hitting a real TSA — unlike the network-gated integration test in internal/evidence. Also adds evidence.TimestampTime(), extracted from the parsing logic already used by the TSA client, since the dossier needs to show the timestamped time to a human reader.
