test(dynamodb): prove protect-dynamodb 6.0.1 items read and query under Stack 1.x - #1436
Turns the claims in our Protect.js → Stack 1.x DynamoDB migration write-up into tests.
Until now, every v2 test minted its "v2" fixtures with today's protect-ffi running in v2 mode. Compatibility with ciphertext written by the old native client (protect-ffi 0.18.1 / cipherstash-client 0.28) was argued from source, and no test pinned it.
Credentialed e2e: e2e/tests/protect-dynamodb-compat.e2e.test.ts (24 tests, green against live ZeroKMS)
This suite mints items with the real @cipherstash/protect@10.2.1 + @cipherstash/protect-dynamodb@6.0.1, added as exact-pinned devDependencies of the private @cipherstash/e2e package. It then reads them with the in-tree stack and checks:
Q1 decrypt: reads with storedEqlVersion: 2 and with no version, on both the single and bulk paths. Results agree with protect-dynamodb's own decrypt. A bigint column comes back as a JS bigint from Stack and a number from Protect, with the same value. Tampered ciphertext fails rather than returning wrong plaintext.
Q2 __hmac:encryptQuery(...).hm equals the stored HMAC for TextEq, IntegerEq, BigintEq and DoubleEq, and it equals legacy createSearchTerms. Negative cases: IntegerOrd emits no hm, a v3 Boolean writes no __hmac, and a downcase filter only matches when the input is lowercased first.
Q3 binding: items decrypt under a renamed table and renamed DB column names, and the HMAC is bound to neither.
Rollback: an item written by Stack 1.x reads back through protect-dynamodb 6.0.1 and carries the same __hmac.
Legacy dataType('json'): it is stored as a scalar string, encryptedDynamoDB + types.Json fails on it (the known gap), and client.decrypt() on a rebuilt v2 scalar envelope reads it.
What protect 10.2.1 could actually write (found while building the fixture, now pinned):
A dataType('bigint') column takes only a JS number. A JS bigint throws Do not know how to serialize a BigInt, and a string is rejected. So no legacy bigint value exceeds Number.MAX_SAFE_INTEGER exactly.
A dataType('date') column rejects every form: ISO strings, Date, epoch numbers and objects all fail with Unsupported conversion … to Date. So no protect 10.2.1 item carries a date, and there is no legacy date HMAC to match.
Booleans encrypt fine.
Items are minted at test time rather than committed, because ciphertext and HMACs are bound to the keyset (the same trap as #1200). No DynamoDB is needed.
CI wiring (tests.yml, e2e-tests job)
The existing turbo run test:e2e step runs under turbo's strict env mode, which filters out the CS_* variables, so every credentialed e2e suite in that job has been skipping. This PR adds a dedicated step that runs the compat suite with plain vitest, with CS_E2E_REQUIRE_AUTH=1 so missing credentials fail instead of skipping.
The old client doesn't derive its endpoints from the workspace CRN, and the job pins ap-southeast-2 hosts while the CI workspace is in us-east-2. The suite sets CS_CTS_HOST / CS_ZEROKMS_HOST from the CRN's region before creating the protect client.
I didn't switch the turbo step to --env-mode=loose. That un-skips prisma-example-readme.e2e.test.ts, which is broken on main (ERR_PACKAGE_PATH_NOT_EXPORTED ./control from stack-prisma) and is out of scope here.
A legacy scalar JSON item: the adapter drops the stored ciphertext and the read fails. This pins the gap.
A renamed property key: decryptModel returns the raw ciphertext inside a successful { data }.
Supply chain note
This adds @cipherstash/protect@10.2.1, @cipherstash/protect-dynamodb@6.0.1, @cipherstash/schema@2.0.2 and @cipherstash/protect-ffi@0.18.1 (with its platform packages) to the lockfile, all first-party. Only the private e2e package depends on them. None has an install script, and onlyBuiltDependencies is unchanged.
No changeset: the change is test-only, and the e2e package is private.
Expanded compatibility coverage for protected DynamoDB data across legacy and current versions, including reads, writes, queries, migration and backfill flows, and rollback reads.
Added checks for legacy JSON data, renamed attributes, HMAC behavior, tampered data, and cases where older data cannot be read or behaves differently across versions.
The authenticated compatibility test now runs in the end-to-end workflow and requires credentials.

Walkthrough
The pull request adds authenticated end-to-end tests for Protect and Stack DynamoDB compatibility. It adds Stack tests for legacy scalar JSON and renamed-property reads. CI removes fixed service-host overrides and runs the compatibility test with authentication required.
The E2E package adds Protect dependencies. The test loads credentials and defines schemas and helpers. CI removes fixed service-host settings and runs the test with authentication required.
Test legacy item creation and reads e2e/tests/protect-dynamodb-compat.e2e.test.ts, languages/typescript/packages/stack/__tests__/dynamodb/v2-type-coverage.test.ts
The compatibility suite checks legacy item fields, Stack and Protect reads, bulk reads, tampered ciphertext, and renamed mappings. Stack tests cover legacy scalar JSON failure and renamed-property pass-through.
Test HMAC mappings and migration paths e2e/tests/protect-dynamodb-compat.e2e.test.ts
The suite compares HMAC behavior across values and domains, checks downcase behavior and rollback reads, and exercises partial updates, backfill, mixed-generation reads and queries, and stale HMAC removal.
Test legacy JSON and Stack 0.19 bridge e2e/tests/protect-dynamodb-compat.e2e.test.ts
The suite tests legacy scalar JSON handling, re-encryption and readback, and the deprecated Stack 0.19 bridge.
This change adds compatibility tests and a CI step that exercise legacy protect-dynamodb items under Stack 1.x. It does not alter shipped runtime behavior. No actionable merge-blocking risk remains.

Use a real DynamoDB path for the persistence assertion.
The test exercises the real encryptModel and decryptModel transformations, but the stale-Boolean assertion uses a Map for SET, REMOVE, and query behavior. It therefore does not cover DynamoDB update or query operations.
Move this scenario to a unit suite, or use real DynamoDB update and query operations in this e2e test. This is a test-coverage refactor, not a major product defect.

…rough
Offline coverage in the stack package: a Protect dataType("json") column was
stored as a scalar ciphertext, which encryptedDynamoDB cannot read as
types.Json, and a renamed property key passes raw ciphertext through rather
than failing.

…ack 1.x
Mints items with the real @cipherstash/protect 10.2.1 and
@cipherstash/protect-dynamodb 6.0.1 (pinned devDependencies) at test time and
checks them against the in-tree Stack:
- only __source and __hmac are stored; no EQL version is on disk
- Stack 1.x decrypts them, with or without storedEqlVersion: 2, agreeing with
Protect (bigint now comes back as a native bigint)
- which v3 domains keep the stored __hmac (TextEq, IntegerEq, BigintEq) and
which lose it (IntegerOrd, Boolean), plus the downcase rule v3 leaves to the
application
- Stack-written items still read under Protect, for rollback
- a customer-shaped acceptance run: legacy write, mixed partial update,
backfill, query and rollback, including the stale __hmac a Boolean partial
update must REMOVE
- Protect's scalar dataType("json") values, readable via client.decrypt and
backfillable to types.Json
cipherstash-client 0.28 does not derive service hosts from the CRN, so the
suite points CS_CTS_HOST / CS_ZEROKMS_HOST at the CRN's region while Protect's
client is built, then restores them. It needs all four CS_* credentials and
throws, rather than skipping, when CS_E2E_REQUIRE_AUTH=1 and any is missing.

turbo's strict env mode hides CS_* from turbo run test:e2e, so the suite runs
in its own vitest step with CS_E2E_REQUIRE_AUTH=1. The region-pinned
CS_ZEROKMS_HOST / CS_CTS_HOST overrides are dropped: the suite scopes its own
override to Protect's client, and Stack derives its hosts from the CRN.

Earlier guidance routed Protect apps through @cipherstash/stack@0.19.0 before
Stack 1.x. The direct path is proven above, so that hop is no longer
required. This clearly marked DEPRECATED block shows that anyone who did take
it lands in the same place: 0.19 reads Protect's items, re-writes the same
__hmac values, and Stack 1.x reads and queries the result exactly as it does
the Protect item.
0.19.0 is pinned as the npm alias @cipherstash/stack-0.19 (no install
scripts; its protect-ffi 0.28.0 and auth 0.41.0 have none either).
