Last link of the ten-link import-format stack. Links 1-9 deliberately wrote
no changelog and no documentation, to avoid a conflict at every level of a
linear pile; this link owes all of it.
- ADR 0019 records the structuring decision: the import format is a fully
persisted value, never re-inferred. It documents the three independent paths
by which it used to be lost (hardcoded restore, header drift, data export),
and why a single codec with a completeness test closes the class rather than
a composed type -- the two carriers are structurally incompatible
(`has_header` is boolean on one and number on the other). `template_id` is
recorded as a provenance label, never re-read as format.
- `docs/architecture.md` gains a dedicated "Import CSV" section covering the
codec, the lexical detection layer and its separate dictionary module, the
bank signatures, the now-mandatory preview step, and sources/templates in
the SREF envelope. Migration v17 and its four CHECK-guarded columns are
listed in the migrations table.
- Stale counts corrected against the tree, not by arithmetic: 16 -> 17
migrations (both files), `src/components/import/` 13 -> 14, `src/utils/`
4 -> 13. Tables (20) and indexes (24) were re-measured and are NOT stale --
v17 is an ALTER TABLE only -- so they are left as they are, with the reason
written down. ADR 0018, missing from the ADR table, is added.
- The user guide and the `docs.*` keys in both locales carry the same new
import journey: automatic detection, confidence score, mandatory preview
with its signed recap, sign inversion, recognised bank formats, drift panel,
and the safe repair path.
- Both changelogs carry the same entries, translated, verified section by
section including issue references. The `public/` copies sync automatically
via `syncChangelogs()`.
