fix(plugins): follow the identifier the schemas moved to

[LKSNDRTMLKV]

Found auditing what #295 left behind. It migrated the schemas, the Rust types,
the catalog and the stored-data lens to productIdentifier — and touched
zero files under plugins/.

What was broken

Nine of the ten plugins still called require_gtin("gtin"). That reads a flat
top-level key (present() is input.get(key), no path traversal), and the GTIN
now lives one level down:

{ "productIdentifier": { "scheme": "gs1", "gtin": "09506000134352" } }

Proven rather than argued — the battery plugin, fed the exact shape dpp-domain
serialises today:

Err(ValidationErrors([PluginFieldError {
    field: "/gtin", code: "missing", message: "gtin is required" }]))

🚨 It failed silently, which is the part that matters

Both consumers of a determination discard the error. The publish-time gate:

if passport_obligation_live(...)
    && let Ok(determination) = self.compliance.compute(...)   // Err -> short-circuits
    && determination.has_violations()

An Err makes the whole condition false, so the gate that blocks a passport
carrying binding violations does not fire. Passports published with no
compliance determination at all, across nine product groups. Nothing logged a
failure because nothing treated it as one.

The two fail-open call sites are in the consumer, not here, and are being fixed
separately along with dispatch-time schema enforcement.

Why five gates all missed it

• plugins/* are excluded from the workspace — cargo check --workspace
  never compiled them against the new shape.
• Their own tests passed because the fixtures still carried
  "gtin": "12345678901231". A test pinned to a shape that no longer ships —
  the same defect class as the stale schema version literal fixed in fix(tests): point the leak guard at the shipping schema #317.
• The catalog↔schema parity test compares those two records to each other. It
  never asks what a plugin requires.
• Every plugin declared a stale schema_version_range, but it is dead metadata:
  the host calls check_compatibility(…, None, …) and None skips the schema
  check entirely.
• Both call sites swallow the error.

The change

Validator::require_product_identifier picks the branch by declared scheme:
scheme 1 keeps the GTIN check-digit test the bare field used to get, scheme 2
requires an absolute url, scheme 3 a did under one of the three methods
clause 5 names. The three are alternatives, not a hierarchy — asking every
record for a GTIN is what made schemes 2 and 3 unusable.

An unmapped scheme is refused rather than skipped. "passport_id" is
exactly the invented scheme that otherwise passes unexamined, so it now fails at
the plugin tier too:

PROBE gs1      -> Ok(())
PROBE did      -> Ok(())
PROBE invented -> Err([/productIdentifier/scheme: unknown])

require_gtin stays — it is still correct for a bare GS1 field, and
require_product_identifier uses it internally for the scheme 1 branch.

Ten stale version ranges bumped to the versions their product groups serve.

Verification

just check green, 1561/1561. The six new SDK tests were mutation-tested,
not just run: breaking the check-digit branch fails
a_malformed_branch_value_is_refused_per_scheme, so the guard is real.

The plugin diffs are deliberately pure substitution — no cargo fmt reflow
rode along, since plugins/* are not covered by fmt-check and had drifted.

Not in scope

Two pre-existing gaps found in the same audit are filed separately: battery
never validates batteryType despite it being schema-required, and no plugin
validates productIdentifier beyond what this PR adds (textile, which never
required a GTIN, still does not check it).

📝 Walkthrough

Walkthrough

The SDK adds Validator::require_product_identifier with scheme-specific validation. Product-group plugins now require structured productIdentifier values, update fixtures, and extend supported schema ranges. The changelog documents the migration.

Changes

Product identifier migration

Layer / File(s)	Summary
Product identifier validation crates/dpp-plugin-sdk/src/validate.rs, crates/dpp-plugin-sdk/src/tests.rs	The SDK validates GS1, identification-link, and DID identifiers. It reports nested validation paths and covers missing, malformed, and unknown schemes.
Plugin validation and schema updates plugins/product-group-*/src/lib.rs	Product-group plugins require productIdentifier instead of top-level gtin. Supported schema maximums and valid test fixtures are updated. Battery tests also migrate related fixtures.
Migration documentation CHANGELOG.md	The changelog documents the identifier migration, schema range updates, and Validator::require_product_identifier behavior.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 8d33e

Malformed product identifiers can pass validation across the migrated plugins, undermining compliance checks. This should be corrected before merge.

replace the claim that it calls require_gtin internally with wording that it
applies the same validation checks for the scheme 1 branch.

In `@crates/dpp-plugin-sdk/src/validate.rs`:
- Around line 204-223: Strengthen require_product_identifier URL and DID
validation to match ProductIdentifier::identification_link and
ProductIdentifier::did, rejecting malformed values such as https:///path and
did:web: with whitespace rather than relying only on prefixes and non-empty
remainders. Update the visible URL and did validation branches while preserving
valid absolute URLs and supported DID methods, and add regression tests covering
these malformed values.

In `@plugins/product-group-battery/src/lib.rs`:
- Line 52: Update the supported-range comment associated with the max_version
configuration to state that the battery schema is supported through v2.7.0,
matching the "2.7.0" value assigned to max_version.

[LKSNDRTMLKV]

All three findings were valid against the code and are fixed in f9cfbfa.

The major one is fixed one level up rather than in place. require_product_identifier did accept https:///acme/1 and did:web: , and the reason it did is that the rule existed twice — dpp_domain::identifier::ProductIdentifier tested the authority and the W3C DID grammar, the SDK tested a prefix and a non-empty remainder. Patching the SDK copy to match would have left two copies to disagree again, and the domain already carried a comment naming the exact https:///p/1 case that the SDK copy did not inherit.

So the syntax now has one home: dpp_rules::common::identifier (is_absolute_web_url, check_did, DID_METHODS). dpp-rules is no_std, zero-dependency, and already a dependency of both tiers precisely so neither has to depend on the other. DidRejection carries the method name so the domain keeps its three distinct error variants and a plugin gets one field message.

Regression tests added at both tiers, and mutation-tested: reverting the predicates to the prefix-and-remainder logic fails a_carrier_shaped_value_with_nothing_to_resolve_is_refused, so the guard bites rather than merely existing.

The two minor findings: the battery range comment now reads v2.7.0 (the real max — every other plugin was checked, only battery carried such a comment), and the CHANGELOG no longer claims require_product_identifier calls require_gtin internally.

just check green, 1564/1564 (was 1561).

Note dpp_rules::common::identifier carries a LAYOUT-DEVIATION: rule 15 counts a shared bucket's users among its in-crate siblings, and this module's two users are other crates, so the count it can see is zero. The sharing is real, just not the kind that rule can observe.
