refactor: always include plugin component ordinals - #886
Conversation
Signed-off-by: Bryan Bednarski <bbednarski@nvidia.com>
WalkthroughPlugin component namespaces now use versioned, percent-encoded names with one-based ordinals. Initialization no longer calculates total component counts. Runtime registration identity parsing, middleware qualification, tests, and documentation use the new format. ChangesPlugin namespace ordinal
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change makes singleton plugin names include ordinal 1. A bounded merge-readiness risk remains because non-plugin registrations may be able to use the same namespace prefix and receive misleading plugin ownership metadata; merge is reasonable with explicit owner follow-up to reserve that prefix or document ownership as advisory. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)
Full details: Description checkExplanation The description includes all required template sections, both confirmation checkboxes, implementation details, reviewer guidance, and a related-issues entry. It clearly describes the ordinal namespace change and breaking behavior. Full details: Docstring CoverageExplanation Docstring coverage is 51.11% which is insufficient.

- Around line 4066-4074: Refactor the qualified-name construction in
PluginRegistrationContext::qualify_name and this native guardrail path to share
one small qualification value/helper with a single qualify method. Preserve both
encode_local_names behaviors byte-for-byte, including namespace concatenation
and encode_plugin_component_field handling, so registry decoding and all plugin
registrations remain identical.

2848-2894: 🗄️ Data Integrity & IntegrationNo legacy namespace migration issue
The legacy string appears only in tests as an arbitrary global registration and as a decoder rejection case. Component construction uses
nemo-relay-plugin.v1, while bindings and worker SDKs forward effective names without parsing them. Theplugin::0::targetvalues are test fixtures, not namespace producers.> Likely an incorrect or invalid review comment.crates/core/tests/unit/plugin_tests.rs (2)

The profile prefix was already percent-encoded under plugin-component namespaces. This change preserves the existing effective profile namespace.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win
Reuse one qualification helper instead of duplicating qualify_name.
This block duplicates both branches of PluginRegistrationContext::qualify_name. The two copies must stay byte-identical, otherwise native guardrail names stop matching registry decoding and the plugin's other registrations. Extract the namespace plus mode into a small value with one qualify method and use it in both places.

In `@crates/core/src/plugin/dynamic/native.rs` around lines 4066 - 4074, Refactor
the qualified-name construction in PluginRegistrationContext::qualify_name and
this native guardrail path to share one small qualification value/helper with a
single qualify method. Preserve both encode_local_names behaviors byte-for-byte,
including namespace concatenation and encode_plugin_component_field handling, so
registry decoding and all plugin registrations remain identical.

#### Overview
Relay creates effective names for dynamically registered plugin components so runtime discovery and middleware gates can unambiguously identify their owner. This change replaces the ambiguous dunder naming with a versioned, parsed format that carries the plugin kind, an always-present one-based component ordinal, and the local registration name. It makes singleton and multi-component registrations follow the same contract while retaining structured discovery as the stable client-facing identity.

- [x] I searched existing issues and open pull requests, and this does not duplicate existing work.
#### Details
- Replace the ambiguous dunder key with the versioned v1 grammar: `nemo-relay-plugin.v1.{percent-encoded-kind}:{one-based-ordinal}:{percent-encoded-local-name}`.
- Percent-encode UTF-8 component kinds and local names using RFC 3986 unreserved-character rules, and strictly decode only canonical v1 names. Invalid, legacy, and ordinary global names retain the global-API fallback.
- Preserve the existing discovery, worker, FFI, Python, Node, and Go owner transport. Relay-created plugin-component discovery now consistently reports `component_ordinal: Some(1)` for a singleton.
- Preserve encoding for PII child contexts and native runtime-created conditional-middleware gate names.
- Update exact cross-language expectations and the conditional-middleware guide.
Breaking behavior: effective names for Relay-created plugin components change from the unmerged dunder format to the v1 format. The structured discovery identity remains the public contract; clients must discover effective names and must not construct or persist them.
#### Where should the reviewer start?
Start with `crates/core/src/plugin.rs` for the namespace encoder/decoder, then `crates/core/src/api/registry.rs` for strict ownership discovery and `crates/core/tests/unit/plugin_tests.rs` for encoded-field and global-fallback coverage.
