Closes #554 and #562. dpp-core 0.23.0 is published (from e1e1e60b, tagged v0.23.0), and this builds against it from crates.io.

This is the repin to dpp-core 0.23.0. Before core published, it was the consumer check dpp-core's release checklist asks for: built against the core release commit (e1e1e60b) through a [patch.crates-io] that was never committed, and run on CI with .github/workflows/core-candidate.yml. The patch is gone now: Cargo.lock resolves the published 0.23.0 crates, whose checksums match the uploads.

main is merged in after the 0.15.0 release (#560) and #575, and so is #574's branch: the v0.15.0 upgrade fixture and one upgrade test per captured release.

What changes

  • The pins. Cargo.toml (9 crates), fuzz/Cargo.toml (dpp-domain, dpp-vc) and the plugin SDK ABI guest (crates/dpp-plugin-host/tests/fixtures/abi-echo/Cargo.toml) move to 0.23.0.
  • The enum check. CORE_VERSION_VERIFIED in openapi_contract.rs moves to 0.23.0 after the six enums it lists were compared at v0.22.0 and e1e1e60b: none gained or lost a variant.
  • The new core fields. FacilitySnapshot and ResponsibleOperator gain identifier, and BatteryData gains due_diligence_operator_scope. Every literal sets them to None. actor_identifier() reads the legacy scheme and value when identifier is unset, and leaving it unset keeps stored documents byte for byte.
  • Transfer notifications answer with a TransferReport. It is feat: type registry outcomes, recover handles #484's transfer code unchanged, apart from one identifier: None: the adapter sends the transfer's own id as the Idempotency-Key and reads a 409 naming that key as already held; the drain closes the row on Accepted or AlreadyHeld, records a Refused with the registry's reasons, and sends Processing and anything unrecognised again under the same key.
  • The battery content table takes BatteryFacts. The template gates ask it with the facts of a battery placed on 18 February 2027, the demo-passport gate with each file's own placing date, and the OpenAPI contract test with one count before 18 August 2027 and one from that date.
  • Registration needs an EN 18219 clause 6 route. The registry adapter's fixtures use an LEI, and a test checks that a VAT number and a DID are refused before anything is sent.
  • Publish refuses an identifier a registration cannot carry, for a passport that has never queued one (A VAT or EORI primary identifier queues registrations refused on every attempt #562). Publish reads the primary identifier's scheme and the facility's identifier through core's ActorIdentifier::from_legacy and FacilitySnapshot::actor_identifier. Where the obligation is live and the passport has no registration row yet, it refuses with 422 and the reason unregistrable_identity. A passport that already has a row is not refused: its identifier cannot change, and refusing would only keep a suspended passport from being re-activated. Its registration is queued as before, which leaves a pending or registered row alone and queues a rejected one again, for the drain to reject again with its reason.
  • A draft is published under the operator's primary identifier as it stands at publish. It kept the one stamped at create, and an amendment's successor its predecessor's. After an operator moved its primary from a VAT number to an LEI, as the migration says to, it went on publishing under the VAT number with a registration that named no scheme. A re-publish keeps the identifier it was signed with.
  • The registration drain rejects a payload the adapter refuses before sending (A VAT or EORI primary identifier queues registrations refused on every attempt #562), instead of retrying it with no end. Network and registry failures are still retried.
  • The upgrade test applies the documented migration. After booting over a captured release, operator_paths.rs makes an LEI primary where the fixture's primary is a VAT or EORI number, as the Breaking entry tells an operator to, and then requires every passport to suspend, re-activate and amend, with the successor under the LEI.
  • Test identities, the JSON-LD tests, the battery placing date, the 2.10.0 and 1.5.0 fixtures and PublishReadiness, as before.
  • CHANGELOG.md: three Breaking entries and four Fixed entries under [Unreleased], each citing this pull request or A VAT or EORI primary identifier queues registrations refused on every attempt #562.

The consumer check found two defects here, not in core

Run against e1e1e60b with both captured releases, the upgrade test failed:

  1. A passport published before the upgrade could not be re-activated. Both fixtures have a VAT primary identifier and pending registrations, as any 0.14 or 0.15 node may. The first version of the A VAT or EORI primary identifier queues registrations refused on every attempt #562 refusal turned every re-publish down. Fixed as above. an_unregistrable_identity_is_refused_only_before_a_registration_was_queued covers a pending and a rejected row.
  2. An amendment after the migration was published under the old identifier. Fixed by the re-stamp above. a_draft_is_published_under_the_operators_current_primary_identifier covers it, and failed before the fix.

Checked, with the local patch to core e1e1e60b

  • just check: 1647 tests, cargo audit and cargo deny clean.
  • Integration tiers: dpp-dal 124, dpp-vault 520, dpp-plugin-host 71, dpp-node 385, including the upgrade from v0.14.0 and v0.15.0.
  • core-candidate.yml on this branch with core_ref e1e1e60b: green in every step, in the run linked below. Its log shows every core crate, dpp-plugin-sdk among them, compiled from the candidate checkout at 0.23.0. The first run found the override missing dpp-plugin-sdk (fixed in 840c1d7d), and the second hit a flaky test on main (fixed in test(node): point the unreachable registry at port 1 #575).

Found here, not fixed

Against the published crates

  • Cargo.lock re-resolved from crates.io with no patch: the ten core crates move to 0.23.0 and the jsonschema family to 0.60.2, which core 0.23.0 requires. Nothing else moves. fuzz/ and the ABI guest keep untracked locks.
  • With no patch and --locked: just check 1647 tests; integration tiers dpp-dal 124, dpp-vault 520, dpp-plugin-host 71, dpp-node 385; and the plugin SDK ABI test with dpp-plugin-sdk 0.23.0 resolved from crates.io.
  • main (with test(node): point the unreachable registry at port 1 #575) and test(node): capture the v0.15.0 upgrade fixture #574's branch are merged in, so the upgrade runs as one test per captured release (v0_14_0_upgrades_to_this_build, v0_15_0_upgrades_to_this_build), each under the slow-test budget. After the merge: just check 1648 tests, and onboarding plus both upgrades pass against the published crates. When test(node): capture the v0.15.0 upgrade fixture #574 lands on main, taking it again changes no file here.

Summary by CodeRabbit

  • Breaking Changes
    • When product-group registration is required, publishing now requires an operator identifier with a supported registration route. Without a live registration obligation, publishing can proceed without registration.
    • Battery passports now require a placing-on-market date. From 18 August 2027, due-diligence scope may also be required unless the battery is exempt.
    • Anonymous access to critical-material weights and origins is restricted for newer battery and electronics passport versions.
  • Bug Fixes
    • Transfer notifications now handle duplicate submissions consistently, and registry responses are reflected more accurately.
    • Invalid registration details are rejected before submission, with clearer outcomes.
    • Publishing uses the current primary operator identifier when appropriate.
  • Documentation
    • Updated setup and quick-start examples to use LEI identifiers.

Walkthrough

The pull request updates the workspace to dpp-core 0.23.0 and adapts battery requirements, operator registration, and transfer notification handling. It also updates registry and resolver tests, fixtures, examples, and documentation.

Changes: Core Repin and Battery Requirements

Layer / File(s) Summary
Core version and data-shape updates
Cargo.toml, fuzz/Cargo.toml, .cargo/config.toml.example, crates/dpp-plugin-host/..., crates/dpp-dal/..., crates/dpp-node/tests/openapi_contract.rs, crates/dpp-vault/..., crates/dpp-integrator/...
Workspace and fuzz dependencies move from 0.22.0 to 0.23.0. The plugin ABI fixture uses the sibling dpp-core checkout. Fixtures initialize added fields, including FacilitySnapshot.identifier and BatteryData.due_diligence_operator_scope.
Battery facts and publish requirements
api/components/schemas/passport/PublishReadiness.yaml, crates/dpp-integrator/..., crates/dpp-vault/tests/battery.rs, crates/dpp-vault/tests/demo_passports_publish.rs, crates/dpp-node/tests/openapi_contract.rs, CHANGELOG.md
Battery rule checks now receive placement-date facts. Tests cover required fields before and at the due-diligence threshold. The API description and changelog record the placement-date and due-diligence requirements.

Operator Identity and Registration

Layer / File(s) Summary
Publish-time identity and registration eligibility
crates/dpp-vault/src/domain/service/publish.rs, crates/dpp-vault/tests/facility_operator_stamping.rs, crates/dpp-node/tests/operator_paths.rs, crates/dpp-vault/tests/*, crates/dpp-node/tests/smoke.rs, docs/guides/*, README.md, cli/README.md, scripts/capture-upgrade-fixture.sh, CHANGELOG.md, docs/ops/METRICS-PLAN.md
Drafts publish under the current primary identifier when one is available. When registration is owed, publishing checks whether operator and facility identities are registrable and handles existing registration rows. Tests and examples use LEI identifiers; the metrics plan adds unregistrable_identity.
Registration adapter and outbox validation
crates/dpp-node/src/infra/registry/{mapping,tests}.rs, crates/dpp-node/src/infra/registry_drain.rs, crates/dpp-node/tests/registry_outbox.rs, CHANGELOG.md
Registration tests cover supported operator schemes. Adapter validation errors reject outbox rows with a recorded reason. If rejection recording fails, the row is retried.

Transfer Notification Idempotency

Layer / File(s) Summary
Transfer reports and idempotent requests
crates/dpp-node/src/infra/registry/{client,mapping,tests}.rs, crates/dpp-node/tests/registry_outbox.rs, CHANGELOG.md
Transfer requests send the transfer ID as the idempotency key. Registry responses map to TransferReport outcomes, including AlreadyHeld for a matching replay-key conflict.
Transfer outbox outcomes and retries
crates/dpp-node/src/infra/transfer_drain.rs, crates/dpp-node/tests/transfer_outbox.rs, crates/dpp-node/tests/registry_outbox.rs
The drain marks accepted and already-held notifications as notified, records refusals, and retries processing or unrecognized replies. Adapter validation errors are recorded as rejections.

Resolver Access Checks

Layer / File(s) Summary
Context-aware restricted-field checks
crates/dpp-resolver/src/jws_verification_tests.rs, crates/dpp-resolver/tests/resolver_e2e.rs, crates/dpp-dal/tests/fixtures/passport_docs/*, CHANGELOG.md
Resolver assertions remove the top-level @context before checking response fields. New battery and electronics passport fixtures are added. The changelog records the access classifications for the newer schema versions.

Merge Risk: Low · up to dd92f

The update is mergeable with awareness of narrow identity and retry-handling gaps. Transfers can omit a supplied typed identifier, and an unusual publish path can queue an unusable registration. Battery CSV support for the August 2027 requirements remains deferred.

Full details: Title check

Explanation

The title "chore!: repin dpp-core 0.23.0" matches the main change: the workspace and fuzz dependency pins move from dpp-core 0.22.0 to 0.23.0, with the compile fixes that follow from it. It is short, specific, and follows the conventional-commit style. The breaking marker (!) fits the changelog's Breaking entries.

Full details: Description check

Explanation

The description follows the template. It has a Summary, a Related issue section (Closes #554 and #562), a Changes section with bullets, and a Checklist. It covers the repin, the new core fields, the TransferReport change, the BatteryFacts change, the registration and publish handling, and the drain behaviour. It also gives detailed validation results and an open item (#563). Some checklist items are not confirmed in the text. The description does not say that a Docker integration run was done for the 0.23.0 pins without the patch, and the objectives note the same gap. The changelog entry and the no-changelog state are described in the Changes section, but the checklist is not ticked.

Full details: Out of Scope Changes check

Explanation

The dependency pins, core-field adaptations, BatteryFacts changes, registry transfer handling, JSON-LD test updates, fixtures, upgrade tests, and documentation support the dpp-core 0.23.0 repin and its stated compatibility work. The identifier and registration changes are stated PR objectives and have focused tests. No demonstrated unrelated change is present.

Full details: Docstring Coverage

Explanation

Docstring coverage is 83.33% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 30 functions across 33 files. (14 skipped: 14 unsupported.)

Full details: New Dependency Is Justified

Explanation

No new direct dependency is added. The reviewed Cargo.toml changes only repin existing dependencies from 0.22.0 to 0.23.0, including the fuzz manifest and the ABI fixture. This check therefore passes trivially.

Full details: Linked Issues check

Explanation

[#554] The dependency pins and core 0.23.0 compatibility changes are present. The PR reports passing just check and published-crate integration tiers. The Docker integration-tier result is not reported, so that part remains unverified.

[#563] The requirement is not met. columns_for has no dueDiligenceUrl or dueDiligenceOperatorScope columns. The importer does not parse DueDiligenceOperatorScope. The PR adds only documentation of this gap. No test proves publication of an imported battery from 18 August 2027 with both fields.

Resolution

Add both due-diligence columns to all three battery CSV templates. Parse and validate DueDiligenceOperatorScope, including an error for unknown values that names the row. Add template-gate coverage before and from 18 August 2027. Add an integration test that imports and publishes a qualifying battery with both fields. Provide the #554 Docker integration-tier result to resolve the remaining verification gap.

Full details: Publication Boundary

Explanation

The reviewed diff contains no detected prohibited item. It only adds the permitted dpp-core repository path and synthetic fixture identities using .example domains. However, the supplied pull request description is truncated after “Test identities, the JSON-LD”. The check explicitly covers the pull request description, and the full text is not available in the checkout or through the available tools.

Resolution

Provide the complete pull request description. Review the omitted text for ADR references, non-public repository names or paths, commercial terms, vendor negotiation data, or real company or individual names in non-public arrangements. If none occur, record PASS.

Populate identifier in the ResponsibleOperator maximal fixture.

responsible_operator() sets identifier: None. The module header requires every Option in a maximal fixture to be Some, because the key-set check cannot observe a field that serializes to nothing. A populated identifier would be compared with the ResponsibleOperator schema, which does not declare that property. Confirm how the pinned dpp-core serializes identifier before changing the fixture or the schema.

Assert the field added at the threshold by name, not only the count.

The owing-date assertion checks only that the number of mandatory fields rises by one. A rules change could add a different field at the threshold and keep the count at count + 1. The assertion would still pass, even though PublishReadiness attributes the added data point to the due diligence report.

Collect the mandatory fields before the threshold and the fields owed from 18 August 2027 as sets. Assert that their difference is the due diligence report field from dpp-rules. Use the field name from the dpp-rules mandatory-field list. The count check can then follow from the set difference.

This is a test-coverage gap. The current implementation is not shown to be wrong.

Add a suspended re-publish case under a VAT primary.

The existing loop publishes only new drafts and never suspends a passport. The upgrade test switches the primary to an LEI before its suspended re-publish. A change that refuses suspended passports under a VAT primary would pass both tests.

Extend the existing VAT-primary setup with this sequence:

  1. Create a draft with POST /api/v1/dpp and insert a pending registry_sync row for it.
  2. Publish it with POST /api/v1/dpp/{id}/publish. Assert 200.
  3. Suspend it with POST /api/v1/dpp/{id}/suspend and an empty JSON body. Assert 200.
  4. Publish it again. Assert 200, and assert that the pending row keeps its status and payload.

Panic on a non-string placedOnMarketDate in the demo helper.

battery_facts maps a number or object placedOnMarketDate to None. The create request deserialises this field as Option<chrono::NaiveDate>, which refuses a non-string value. A demo file with such a value can pass this content test while the create request rejects it. No other test posts the full envelope of the other demo files. All current demo files use string dates, so this is a latent gap in test coverage, not a current production failure. Panic on a non-string value, and keep an explicit null as absent.

Assert the response status in the access-tier loop.

The loop reads each response body and checks only that two field names are absent. A non-success JSON problem response contains neither name, so each iteration passes without a passport being served. Add a status assertion before the body is read, so the test also confirms that the passport is served.

Check each upgrade test body against its fixture argument.

The guard confirms that each v<X>_<Y>_<Z>_upgrades_to_this_build function exists and that its release has a fixture directory. It does not read the function body. A test named for v0.15.0 that calls upgrade_from(&fixture("v0.14.0")) passes this guard, and the v0.15.0 fixture is never upgraded. The doc comment says a fixture without a test is caught here. Extend the check to confirm that each body calls fixture("<release>") with its own release.

Match only enabled upgrade tests when checking fixture coverage.

The contains check at lines 147-149 searches raw source text. A declaration that is commented out, or that lacks #[tokio::test], still matches. A future edit can therefore leave a fixture without a runnable upgrade test while the check passes. CI does not catch this, because --no-tests=fail passes when any other upgrade test runs.

Match only an uncommented declaration that directly follows a #[tokio::test line:

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The drain treats AlreadyHeld as terminal notified even though its preceding Processing report explicitly means received but not applied. A replay conflict might prove only that the key was received, not that processing reached a final decision.

The row remains notified and the eventual refusal is never recorded.

This can occur when: The first POST returns pending, its retry returns a reused-key 409 while processing continues, and the registry later refuses the handover.

129-129: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

transfer_report_for treats a record status of registered as proof that the transfer notification was accepted. The comment says the reply has a record-status shape, so registered may instead describe an already-registered record without establishing that its handover was taken.

The drain permanently marks the transfer notified although the registry has not taken it.

This can occur when: The transfer endpoint returns 200 with status registered for the existing record but does not accept the handover.

601-601: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The newly adapted transfer path still builds its operator IDs through operator_identifier_for, which reads the legacy eu_operator_id fields and ignores the new ResponsibleOperator.identifier field shown in the changed fixtures. A transfer whose typed identifier is its only registry identifier may be sent as a DID instead.

The registry receives the wrong legal-entity identifier and may reject or misattribute the handover.

This can occur when: A completed transfer contains an operator with identifier set to a registrable LEI but eu_operator_id and eu_operator_id_scheme unset.

Add the due diligence declaration to the battery CSV import.

A battery placed on or after 18 August 2027 imports without its due diligence declaration. validate_battery_row sets due_diligence_operator_scope to None (battery.rs:282), and no template column supplies it. dpp-core 0.23.0 refuses to publish that battery, so the imported draft cannot publish. Add dueDiligenceUrl and dueDiligenceOperatorScope columns to the battery templates, and parse the scope in validate_battery_row.

Confirmed, and already tracked as #563 (milestone v0.17.0): the battery templates need dueDiligenceOperatorScope and dueDiligenceUrl columns, and the template gate needs a decision on allowing a column that applies only from a placing date. It stays out of this pull request, which is the repin; the gap is stated in this pull request's Breaking entry.

@LKSNDRTMLKV Understood. The CSV columns and the placing-date template gate decision remain follow-up work in #563 for v0.17.0. Given the documented Breaking entry and the repin scope, I am not requesting those changes in this pull request. The gap remains deferred, not fixed.

Minor · Refuse an empty operator scheme at publish when the passport has no queued… · publish.rs:707-710

crates/dpp-vault/src/domain/service/publish.rs:707-710
Minor · Functional Correctness · Quick win

Refuse an empty operator scheme at publish when the passport has no queued registration.

The gate skips the operator check when operator_scheme is empty, and the doc comment exempts that case. Publish reaches the empty scheme when the operator has no primary identifier, or when the stamped value is no longer the primary one. A draft that keeps its stamp then queues a registration with an empty scheme, and the registry adapter refuses that scheme later. The doc comment says the gate and the adapter must not answer differently, so the publish succeeds for a live-obligation passport that the registry will refuse.

The refused check already keeps passports that have a registration row, so the correction applies only to passports with no row.

so a passport with an operator_identifier and an empty operator_scheme is
refused when it has no queued registration. Keep the existing behavior for
absent identifiers and passports with a registration row, and ensure the refusal

Use the typed identifier when building transfer notifications.

operator_identifier_for in crates/dpp-node/src/infra/registry/mapping.rs reads only the legacy eu_operator_id and eu_operator_id_scheme pair. It never reads the typed identifier field that dpp-domain 0.23.0 adds to ResponsibleOperator. When the legacy pair is absent, the function sends scheme did with the operator DID.

This can occur when a transfer request contains an operator with identifier set and no populated legacy pair. The notification then identifies that operator by its DID, not by the identifier the operator stated. The function's doc comment says it prefers the EU-assigned identifier over the DID.

The fix belongs in operator_identifier_for. It must map the typed identifier to the scheme names that the registry accepts for transfers, and this change does not establish those names.

Review comment at @Cargo.toml at line 55:
Update operator_identifier_for to consider ResponsibleOperator’s typed
identifier when the legacy EU identifier pair is absent, while preserving the
existing preference for the EU-assigned identifier. Establish the
registry-accepted transfer scheme names for typed identifiers before mapping
them; do not guess scheme names.

Log the failed fallback write, and correct the backoff comment.

When mark_rejected fails, the fallback mark_attempt_failed result is discarded. If that write also fails, the row keeps its state and stays due. The comment says the row "backs off like any failure", which is not true in that case. The branch also logs nothing about the fallback failure. Recording a backoff is not possible here, because that record requires the write that just failed.

Update the `mark_rejected` failure branch in the registry drain flow: correct
its comment to state that the row is retried later but may remain due if the
fallback write fails, and log a warning with the passport ID and error when
`mark_attempt_failed` returns an error. Preserve the existing retry accounting.

Handle a failed rejection write in the refusal arm.

The result of mark_rejected is discarded. If the write fails, the row stays pending and its next_attempt_at does not change. The next drain pass can select it again and send it to the registry without backoff. No log entry records the failed write, but stats.rejected still counts the refusal.

The Validation arm in the same match already handles this case. It logs the write error and calls mark_attempt_failed, so the row backs off. Apply the same handling here.

Update the refusal arm handling of mark_rejected so a failed write is logged and
followed by mark_attempt_failed to apply backoff; count the refusal as rejected
only when mark_rejected succeeds, and count the failure through the same
retry-stat behavior as the Validation arm.
