Spec section 8.2: a record whose kind this build does not understand -- one
written by a newer build, or by another application sharing the vault, such
as a future BitLogin namespaced kind -- must be carried through untouched,
never dropped, and must not brick the whole index. TS previously failed the
entire parse on the first unrecognized kind, stranding any shared vault on
older SeedPass builds.
The entry schema is now a union: known kinds validate strictly against the
discriminated union exactly as before, and anything else parses as an opaque
loose record. The refine on the opaque branch is the load-bearing detail --
a malformed record of a KNOWN kind must still fail its own schema, never
fall through and escape validation. Records with no kind or type at all
remain rejected as garbage. Statically the entries map stays typed to the
known kinds (exhaustive switches keep their meaning); the module comment
states the runtime widening plainly.
At the CLI surface, foreign records list with unrecognized fields redacted
to has_* flags -- another application's data is not ours to hand out -- and
reveal refuses with "unsupported entry kind" instead of guessing. Allocation
counts foreign ids, so neighbours never collide with them.
Python's natural tolerance is now pinned by test, which surfaced a real
nuance: Python backfills base-field defaults (tags, links, date_modified)
onto foreign records on load, where TS carries them verbatim. No data is
lost, so both conform to the preservation rule as now worded (no loss, no
reinterpretation; base-field normalization permitted) -- but the two produce
different canonical bytes for the same foreign record, which matters once
foreign kinds sync. Recorded in the spec's gap ledger to align before any
application ships them.
Verified: 4 of the 6 new TS tests fail against the previous schema; 230
core + 152 CLI tests and the cross-impl suite pass with the change.

This was the one remaining gap that could strand a real user: TS refused
any index below schema_version 4, which is every profile written before
tags were added.
- core/schema/migrations.ts ports seedpass.core.migrations exactly,
including the quirks: v1->v2 copies `website` to `label` and drops it
only for password entries; `kind` is NOT backfilled (Python leaves
pre-v2 entries `type`-only and falls back on read). Migration works on a
copy, so a failure can never leave a half-converted vault.
- parseVaultIndex now migrates on open and still refuses future versions;
pass {migrate:false} where silent upgrades are unwanted.
- Two bugs this surfaced: the version probe could not read a v0 index (no
schema_version field at all), and migrated legacy entries failed schema
validation because the discriminator `kind` was missing. The parser now
fills `kind` from `type` at validation time -- the same shape Python
writes for new entries, documented in the matrix.
Evidence: fixtures generated by running Python's own apply_migrations over
v0/v1/v2/v3 payloads, plus cross-impl phase E, which writes a real legacy
v2 index into a Python profile, opens it with the TS CLI, reveals a
migrated secret, and confirms Python still reads the profile afterwards.
162 core + 46 CLI tests green; 16/16 cross-implementation checks green.
