This is the piece that turns a Pre-Publish-Prüfung into an actual
archived, provable record instead of a one-off form response.
extract.Client.Extract now returns Result{Facts, RawJSON} instead of
just Facts — RawJSON is the model's exact, unmodified JSON, which is
what belongs in extraction.payload (the audit trail), not a re-encoded
view through our own Facts struct. extract.ParsePayload reconstructs
Facts from a stored payload later, reusing the same parsing/validation
path Extract uses (including the enum guard), so a previously-saved
extraction can be read back exactly as it would have been the first
time.
internal/dossier.BuildContent no longer requires AssetHash: most checks
right now are caption-only (no image/video upload wired yet), and
inventing a placeholder hash for a nonexistent asset would itself be an
integrity problem in an evidence tool. Content shows "kein Asset
hinterlegt" instead.
internal/web gains a narrow Store interface (mirroring the Extractor
pattern — only the methods these handlers use, not the full
*store.Store) so its test suite stays network/DB-free via an in-memory
fake:
- POST /pruefen persists submission + extraction + findings and marks
the submission "checked". A needsClarification result persists the
extraction (there's something worth keeping) but no findings and no
status change, and the template omits the archive option entirely.
- POST /veroeffentlichen re-derives Facts from the stored payload, hashes
the canonical submission+facts+findings metadata, gets an RFC-3161
timestamp, generates the PDF dossier to disk, and persists the
evidence_package row before marking the submission "published".
- GET /dossier/{id} serves the generated PDF.
Tested end-to-end offline: a fake Timestamper builds a real, structurally
valid self-signed RFC-3161 response so the full check→archive→download
flow runs against an in-memory store, verifying the downloaded bytes are
an actual PDF and the dossier file lands on disk — without hitting a
real database, TSA, or the Claude API.
cmd/deklarix/main.go now wires store.Store, evidence.NewHTTPTimestamper
(TSA_URL, default FreeTSA), and DOSSIER_DIR (default "dossiers") into
web.NewServer alongside the extractor and rule set.

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.
