From 27.1 the store layout is inbuxa's own, and Stalwart is a migration
source. The one Stalwart format inbuxa keeps reading is 0.16.27's, by
export and import. docs/spec/import-0.16.md says what carries over, what
changes on first start, and what the operator has to change.
tests/resources/import-0.16.27 is a real 0.16.27 export (84K): accounts,
a group, a custom role, a tenant, mail with threads and an attachment,
sharing, calendars, contacts, Sieve and a vacation response, plus a
snapshot of what 0.16.27 served. tools/import-check/check.sh imports it
into an image, compares what that serves against the snapshot, less the
known differences (inbuxa's own role and permissions), then checks
delivery through the imported filter, search after the reindex, and
re-saving a pre-rename filter. It passes on 27.1-rc.4.
make-fixture.sh rebuilds the fixture from the pinned 0.16.27 image, with
no internet, so no upstream download ends up in it.
SPEC.md and migration.md no longer promise an unchanged store format.
