Separate HTML adapter for the cosinex Vergabemarktplatz (DTVP) satellite
(sourceType='cosinex-dtvp'), distinct from the NetServer adapter since
cosinex markup differs structurally. Live inspection (2026-07-23) found
the "Aktuelle Bekanntmachungen" results table is fully server-rendered
(not JS-dependent as D-01 anticipated), so selectors are fully populated
rather than falling back to a needs-JS stub — parses publish date,
deadline (or "nv"), title, legal framework/procedure type, buyer name,
and a real per-notice deep link (pid) into RawTenderRecord[].
Rule 1 fix: cosinex serves charset=ISO-8859-1 with raw Latin-1 bytes for
umlauts (not HTML entities); Response.text() always UTF-8-decodes per
the Fetch spec, so the adapter reads arrayBuffer() and decodes explicitly
via TextDecoder('iso-8859-1') to avoid mojibake.
16 spec tests pass against a live-captured fixture (20 rows, transcoded
to UTF-8 on disk): full-fixture parse, deadline/publish date parsing,
nested-<abbr> procedure-type extraction, umlaut decoding, empty/broken
HTML and missing-pid row fallback, fetch-throw/non-2xx fallback, no-axios
and no-input-interpolated-URL guards.
