In `@crates/dpp-dal/src/pg/repo_successor.rs`:
- Line 51: Add id DESC as a secondary sort key to the successor lookup's ORDER
BY clause so rows with equal published_at values are selected deterministically,
and add an integration test covering equal timestamps that asserts the expected
successor is returned.
- Line 50: Update PgSuccessorRepo::successor_of and the public-read lookup flow
to traverse successor links through superseded intermediate records until
reaching the current active descendant, rather than requiring the first matching
row to be active. Preserve the SuccessorLookup contract so a printed carrier
resolves to the current passport, and add a committed A → B → C integration test
asserting that a public read of A returns C.
In `@crates/dpp-node/tests/smoke.rs`:
- Line 2447: Update the smoke test around publish_layered_battery to use a
no-GTIN passport fixture, capture the carrier URL produced during publication,
and request that exact URL for the public read after amendment instead of
constructing /vault/public/dpp/{original_id} directly. Ensure the test follows
the no-GTIN /dpp/{id} carrier path through the amendment flow.

Use a no-GTIN passport and follow its carrier URL.
build_carrier_url uses a GS1 /01/... route when ProductGroupData::gtin() is present and /dpp/{id} only when it is absent. publish_layered_battery supplies GTIN 09506000134352. The smoke test calls /vault/public/dpp/{original_id} directly, so it does not exercise the printed carrier path or detect a no-GTIN carrier regression. The existing no-GTIN fixture only captures source data and does not perform a public read.
Publish a no-GTIN passport, capture its carrier URL, and request that same URL after amendment.

All three taken. The first was a real bug and the best kind of catch — my fix worked once and broke again on the second amendment. @coderabbitai review 1. The chain is now walked, not stepped
Each hop now takes whatever row names the previous one, active or not, and stops at the first that is published. Two consequences worth stating rather than leaving to be found:

Exercise the captured carrier URL in the smoke test. The no-GTIN publish path builds qrCodeUrl from the service resolver base, which defaults to https://id.odal-node.io. The test instead reads {base}/vault/public/dpp/{original_id} through a separately constructed scan URL, so it can pass without testing the generated carrier host or public-route prefix. Configure the smoke service resolver base to the local public endpoint, then use carrier for both public reads.

Closes the reachable half of #236, and takes a different route to it than the issue proposed.
✅ ESPR Art. 9(1): the data carrier links to the digital product passport for the product. A carrier is printed on a physical thing and cannot be recalled, so the record it lands on has to stay the current one across an amendment.
The door that answered differently from the one beside it
A passport carrying a GTIN gets a GS1 Digital Link carrier, and every
/01/{gtin}route resolves on the GTIN alone — so an amended product's printed label already landed on the successor. A passport with no GTIN falls back to/dpp/{id}(build_carrier_url), and that door served the predecessor: a document describing the superseded product, saying"status": "active", pointing nowhere.The
activeis not a bug in the status field. The body this route serves is the decoded payload ofpublicJwsSignature, verbatim — that is what makes it verify against the proof re-attached beside it. Every field in it was frozen at publish,statusincluded, whatever happened to the passport afterwards.Why the successor's body, and not the
statusJwsSignature#236 proposed#236 recommends a second nested proof over
{ id, status, asOf }, on the grounds that a fresher claim on this page has to be authenticated to be safe. That reasoning is right and I am not disputing it — but for a superseded passport there is already a document that satisfies it, and we were not serving it.The successor is published, separately signed, current, and its own
supersedesIdnames the passport that was scanned. So the reader gets the pointer #236 says is missing as part of a document they can verify, with:statusand a fresher one — there is only one document and everything in it is true of it;currentStatuswas partly that it could not survive the trip: the resolver re-attaches exactly one named field from the served body and drops the rest. A different body needs nothing re-attached, so this reaches the HTML, JSON-LD and AAS doors by itself.What is not reached, and is still #236
A passport retired with no successor —
archivedat the end of its retention,deactivatedat end of life. Those keep serving their own frozen view, whosestatusreads as it did at publish. There is nowhere to send a reader and no authenticated way to say "this is over" inside a payload that was signed before it was. That residue is genuinely the nested-proof question, and leaving it stated beats papering it over with a claim a consumer could not check.So I have left #236 open and narrowed rather than closing it.
What this adds
dpp_types::successor::SuccessorLookupPgSuccessorRepoPassportService::successors+with_successorsNonekeeps the old behaviourSupersededarm inpublic_read_handlerNo migration.
supersedes_idhas been a real column onodal.passportsince0004, withidx_passport_supersedesover it. The lookup was a query nobody had written, not data nobody had kept.The port is in
dpp-types, notdpp-domain.PassportRepositoryis core's, and core is deliberately product-agnostic: which record should a scanned carrier land on now is about how a deployment serves passports, not what one is. The archived-version store and the seal inspector already sit on this side for the same reason.Two decisions worth arguing with
An unpublished successor is not an answer. The lookup filters
status = 'active', and that is not an optimisation: an unpublished passport has no public view, so sending a scan there would move the404one step along and make the successor look broken rather than unfinished. Until it publishes, the predecessor's own view is the best there is — which is what this route served before, so the fallback is the old behaviour rather than a new failure.A tie resolves to the newest.
ORDER BY published_at DESCdecides nothing in a healthy estate — the supersede route checks that the successor names this passport, and amend mints exactly one — but a tie has to resolve somewhere and the newest is the only answer that is not arbitrary.Tests
Through the assembled node (
smoke.rs): publish, read the public door and get the passport, amend, then read the same URL again — a carrier printed on a product that has not changed. It must return200with the successor'sid, the successor's correctedproductName,supersedesIdnaming the passport that was scanned, its ownpublicJwsSignature, andstatus: active— which is now true of the record being served. Confirmed to bite: disabling the branch returns the predecessor's id.Against Postgres (
pg_successor.rs): the published successor is found; a draft successor is not (theWHEREclause, which is why this is a Postgres test); and a passport nothing replaced returnsNonerather than an error.The smoke harness wires
