#### Overview Align the Claude Code and Codex plugin E2E fixtures with the documented persistent Relay gateway lifecycle, current sidecar-reuse behavior, and their test-owned observability output. - [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license. - [x] I searched existing issues and open pull requests, and this does not duplicate existing work. #### Details - Run both plugin E2E fixtures against the default persistent gateway port, `127.0.0.1:47632`, rather than generating an MCP-only test port. - Update Codex to expect verified live-sidecar reuse across persistent configuration changes; force reinstall still retires the old sidecar and verifies the rotated provider key. - Keep ATOF output under each test workspace, ignore Codex's known post-terminal rollout-flush warning, and reliably terminate the Claude process group on timeout. #### Where should the reviewer start? Review `scripts/test-claude-plugin-e2e.sh` and `scripts/test-codex-plugin-e2e.sh`, focusing on endpoint setup, sidecar lifecycle, and test-owned ATOF paths. #### Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to) - Relates to: RELAY-858 ## Summary by CodeRabbit - **Tests** - End-to-end testing now uses consistent gateway connections and shared event workspaces for more predictable validation. - Plugin address checks verify the configured connection directly. - Provider-request checks are less dependent on a specific API key value. - Test cleanup now reliably terminates related processes, including forced termination when necessary. - Sidecar tests validate reuse after credential rotation and retirement after forced reinstall. - Known transient Codex rollout errors are handled during testing.

#### Overview Advance the development version from 0.9.0 to 0.10.0, reset the 0.10 release documentation, and keep every current project-owned package reference on 0.10.0 ahead of publication. - [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license. - [x] I searched existing issues and open pull requests, and this does not duplicate existing work. #### Details - Update project-owned Rust, Python, Node.js, OpenClaw, coding-agent plugin, documentation, and checked-example version references to 0.10.0. - Reset the release notes and migration guide to the established 0.10 development skeleton. - Keep fixture lockfiles limited to their internal NeMo Relay package-version changes; no transitive dependency updates are included. - Link the checked Node language-binding example to the local 0.10.0 workspace package until the npm package is published. This removes the stale 0.9 registry artifacts from the lockfile and regenerates the Node attribution inventory. - Extend `just set-version` to cover checked-example SDK pins and refresh their local lockfile records without third-party dependency upgrades. - Validation: `just set-version 0.10.0`, `npm ci --ignore-scripts`, `cargo check --manifest-path examples/language-binding-plugin/rust/Cargo.toml --locked`, `uv lock --locked` for both Python examples, `just docs`, and `uv run pre-commit run`. #### Where should the reviewer start? Start with `Cargo.toml` and `justfile` for the unified version bump and ongoing automation, then `package-lock.json` for the pre-publication Node example resolution, and finally the release notes and migration-guide reset. #### Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to) - Relates to: none ## Summary by CodeRabbit * **Release** * Updated NeMo Relay packages, plugins, integrations, examples, and installation commands to version 0.10.0. * Updated workspace and example dependencies to align with the 0.10.0 release. * **Documentation** * Updated getting-started, integration, worker, and native plugin documentation for 0.10.0. * Added 0.10 release notes and migration guide placeholders; no known issues or migration actions are currently recorded. * Improved documentation for automated example version updates.

#### Overview Adds automatic OTLP exporter creation from OpenTelemetry environment configuration. - [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license. - [x] I searched existing issues and open pull requests, and this does not duplicate existing work. #### Details - Delegate OTLP endpoint, transport, timeout, compression, headers, and resource handling to the Rust OpenTelemetry SDK where applicable. - Preserve Relay endpoint isolation and add strict automatic-export activation and opt-out behavior. - Document supported OTEL variables in a sticky searchable table and add regression coverage. #### Where should the reviewer start? Start with `crates/core/src/observability/plugin_component.rs` for automatic activation and `docs/configure-plugins/observability/opentelemetry.mdx` for the public contract. #### Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to) - Closes RELAY-888 ## Summary by CodeRabbit - **New Features** - Added automatic OpenTelemetry setup through standard OTLP environment variables for traces, logs, and metrics. - Supports signal-specific endpoints, headers, HTTP/gRPC transports, compression, and SDK resource detection. - Honors per-signal settings and SDK-wide telemetry disablement. - Explicit configuration retains transport, batching, resource, and timing controls. - Prevents redirects for Relay-configured OTLP/HTTP exporters. - **Documentation** - Documented automatic configuration, precedence, defaults, and limitations. - Updated observability configuration requirements to version 4; version 3 configurations are no longer supported.

Learning: Within the observability Rust modules, keep signal-generic helpers such as `build_grpc_metadata`, `record_signal_runtime_diagnostic`, and `resolve_http_signal_endpoint` in `otel_signal`. The `otel_logs`, `otel_metrics`, and plugin-routing consumers should depend on these shared helpers without introducing a metrics-to-logs module dependency.

Bound the number of dynamic log pipelines.
Each unique promoted resource key creates an OS thread, a Tokio runtime, a provider, and a logger. The map retains each pipeline for the subscriber lifetime. High-cardinality root metadata can therefore exhaust thread or memory limits and stop log delivery.
Set a maximum pipeline count. Route excess resource keys through the configured-resource fallback and record a bounded diagnostic.

I reproduced the growth behavior locally at 8f644d1c: eight distinct promoted root values created eight retained dynamic log pipelines. Since each pipeline owns a provider and dedicated runtime thread, I agree we need a cap, base-resource fallback, and saturation coverage.

@mnajafian-nv, thank you for reproducing this.
The fix should cap DynamicLogPipeline entries before build_in_owned_runtime runs. Existing routes must remain usable. New routes beyond the cap must use the base provider and emit a bounded saturation diagnostic. Tests should verify the cap, fallback routing, and retained pipeline count.

Bound the number of dynamic metric pipelines.
Each unique promoted resource key creates a provider, processor, and dedicated runtime thread. The map retains every pipeline until the subscriber is dropped. A high-cardinality metadata value can therefore exhaust threads and memory even after its lineage expires.
Add a pipeline limit. If the limit is reached, record a diagnostic and route the event through the base processor.
As per path instructions, review event lifecycle regressions in crates/core/**/*.rs.

Preserve the inherited route when an end event has no active entry.
existing_route can recover an end event's route from its active or completed parent. The signal routers pass that route as root_route to SignalResourceLineage::process.
The End branch removes only the event's own active entry. If that entry is absent, the branch returns None, so the event uses the configured-resource fallback. It also does not archive the recovered route for late child events.
Proposed fix
- let route = self.active.remove(&event.uuid());
+ let route = self.active.remove(&event.uuid()).or(root_route);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

ensure_dynamic_metric_pipeline so build_in_owned_runtime runs before acquiring
the pipelines mutex. Re-acquire the mutex after construction, re-check whether
the pipeline key was inserted by another caller, and insert only when still

Learning: Within the observability Rust modules, keep signal-generic helpers such as `build_grpc_metadata`, `record_signal_runtime_diagnostic`, and `resolve_http_signal_endpoint` in `otel_signal`. The `otel_logs`, `otel_metrics`, and plugin-routing consumers should depend on these shared helpers without introducing a metrics-to-logs module dependency.

746-746: 🗄️ Data Integrity & Integration | ⚡ Quick winThe
Endbranch still discards the inherited route.
existing_routecan recover an end event's route from an active or completed parent, and the routers pass it asroot_route. This branch only removes the event's own active entry. When that entry is absent, the branch returnsNone, so the event falls back to the configured resource and no route is archived for late child events.Proposed fix
- let route = self.active.remove(&event.uuid()); + let route = self.active.remove(&event.uuid()).or(root_route);

Each unique promoted resource key creates an OS thread, a Tokio runtime, a provider, and a logger, and the map retains it for the subscriber lifetime. High-cardinality root metadata can exhaust thread and memory limits.

Each unique promoted resource key creates a provider, a processor, and a dedicated runtime thread, and the map retains it until the subscriber drops. High-cardinality metadata can exhaust threads and memory even after the lineage route expires.
Add a pipeline limit. When the limit is reached, record a diagnostic and route the event through the base processor.

Build dynamic providers outside the pipelines mutex. Both ensure_dynamic_log_pipeline and ensure_dynamic_metric_pipeline hold the pipelines mutex while build_in_owned_runtime waits for provider construction to finish. Subscriber dispatch, route lookups, and provider snapshots can wait for this setup.
The build does not wait for exporter network readiness, so this is transient lock contention rather than a blocking export operation. Build outside the mutex, then re-acquire it and check the key again before insertion. If another caller inserted the key, shut down the unused provider before dropping its runtime.

| Use this page to plan an upgrade to NeMo Relay 0.10. It will collect required | ||
| upgrade actions as they are identified during the 0.10 development cycle. | ||
|
|
||
| If you skip releases, read each release's migration guide and release notes | ||
| in order. | ||
| ## Upgrade to NeMo Relay 0.10 | ||
|
|
||
| ## Upgrade to NeMo Relay 0.9 | ||
|
|
||
| ### Refresh Relay-Managed Coding-Agent Integrations | ||
|
|
||
| After upgrading the CLI, refresh personal Relay-managed integrations before | ||
| starting new sessions: | ||
|
|
||
| ```bash | ||
| nemo-relay integrations refresh | ||
| ``` | ||
|
|
||
| To repair only Codex, use `nemo-relay install codex --force`. It can repair | ||
| Relay-owned marketplace entries that point to missing files. These commands | ||
| apply to personal integrations. | ||
|
|
||
| For daemon bundles managed by an administrator, follow the | ||
| [daemon upgrade workflow](/daemon/operations#upgrade-and-roll-back). Close | ||
| sessions and let workers finish pending requests. Then stop the service and | ||
| replace the binary at the same path. Keep the saved identity state and | ||
| existing bundle files. | ||
|
|
||
| ### Pass Tool Execution Context to Intercepts | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| Tool callbacks use a context object because Relay now provides the optional | ||
| provider tool-call ID with the tool name and arguments. Existing callbacks no | ||
| longer match the public API and must be updated. | ||
| </Warning> | ||
|
|
||
| Tool execution intercepts now receive `ToolExecutionContext` and a | ||
| continuation. The context holds the tool name, arguments, and optional | ||
| provider-issued tool-call ID. The continuation calls the next intercept or | ||
| the tool itself. | ||
|
|
||
| Change Rust, Python, and Go callbacks from `(tool_name, args, next)` to | ||
| `(context, next)`. For Node.js and public C callbacks, replace the argument | ||
| payload with the context. Pass the context's arguments to the continuation. | ||
|
|
||
| Read the name and call ID from the context. Node.js uses `toolName`, `args`, | ||
| and `toolCallId`. Public C callbacks receive `tool_name`, `args`, and | ||
| `tool_call_id` in `context_json`. | ||
|
|
||
| Native and worker plugins that register this callback must exclude Relay 0.8 | ||
| from their supported version range. Set `compat.relay = ">=0.9,<1.0"` or | ||
| another range that meets this rule. Native plugins use version 5 of the | ||
| application binary interface (ABI) for this callback. For binding details and examples, refer to | ||
| [Tool Execution Context](/reference/tool-execution-intercept-outcomes#tool-execution-context). | ||
|
|
||
| ### Retain the Plugin Host Activation | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| NeMo Relay 0.9 uses one plugin host to control when plugins start and stop. Global clear and report functions and | ||
| explicit dynamic activation-spec APIs are removed. Update startup, report | ||
| handling, and shutdown together in each application that hosts plugins. | ||
| </Warning> | ||
|
|
||
| `initialize` now returns a `PluginHostActivation` handle for static and dynamic | ||
| plugins. This handle keeps the plugins active. Keep it for as long as your | ||
| application needs them. | ||
|
|
||
| A process can have only one active handle. Close it before starting another. | ||
| If close fails, keep the handle and try closing it again. | ||
|
|
||
| Use the following APIs to manage the handle in each binding: | ||
|
|
||
| | Binding | Initialize | Read the Report | Close | | ||
| |---|---|---|---| | ||
| | Rust | `nemo_relay::plugin::dynamic::initialize(config, path).await?` | `activation.report()` | `activation.close()?` | | ||
| | Python | `await plugin.initialize(config, path)` | `activation.report` | `await activation.close()` | | ||
| | Node.js | `await plugin.initialize(config, path)` | `activation.report` | `await activation.close()` | | ||
| | Go | `Initialize(config, path)` | `activation.Report()` | `activation.Close()` | | ||
| | C | `nemo_relay_plugin_initialize` | `nemo_relay_plugin_host_activation_report_json` | `nemo_relay_plugin_host_activation_close` | | ||
|
|
||
| Replace global clear calls with the handle's close operation. This includes | ||
| Python `clear()` and `clear_async()`, Node.js `clear()`, Rust | ||
| `clear_plugin_configuration()`, and the matching Go and C calls. Read reports | ||
| from the handle instead of a global report function. | ||
|
|
||
| Apply the following cleanup rules for your binding: | ||
|
|
||
| - In Python, use `async with plugin.activate(config, path)` to close the handle | ||
| when the block ends. | ||
| - In Node.js, call `await relay.flushSubscribers()` before closing the handle. | ||
| This lets queued subscribers finish. For existing dynamic-plugin handles, | ||
| replace the `active` property with `isActive`. | ||
| - In C, inspect the report after closing the handle. Then release the handle | ||
| with `nemo_relay_plugin_host_activation_free`. | ||
|
|
||
| Replace explicit dynamic-plugin setup with file-based setup: | ||
|
|
||
| 1. Move `DynamicPluginActivationSpec` entries to `[[plugins.dynamic]]` records | ||
| in `plugins.toml`. | ||
| 2. Replace `initialize_with_dynamic_plugins` or `initializeWithDynamicPlugins` | ||
| with `initialize`, and pass the file as its optional path. | ||
| 3. Remove calls to Python `load_dynamic_plugin_activation_specs`. The host now | ||
| reads those records from the file. | ||
|
|
||
| In Rust, replace `initialize_plugins` with | ||
| `nemo_relay::plugin::dynamic::initialize`. | ||
|
|
||
| For complete examples, refer to | ||
| [Configure and Initialize Plugins](/configure-plugins/initialize-plugins). | ||
| For dynamic-plugin records, refer to | ||
| [Configure Discoverable Plugins](/configure-plugins/discoverable-plugins). | ||
|
|
||
| ### Validate the Effective Plugin Configuration | ||
|
|
||
| `validate` now checks the same settings, dynamic manifests, version rules, and | ||
| trust policy as `initialize`. It does not load plugin code. | ||
|
|
||
| If you pass a `plugins.toml` path, Relay uses it instead of searching for a | ||
| user file. Relay then merges the system file and applies settings from your | ||
| application code. Check `config_paths` and the redacted `resolved_config` in | ||
| the report to confirm which settings Relay used. | ||
|
|
||
| Use exact validation to check only a complete static document in memory. | ||
| It does not read files. Choose the API for your binding: | ||
|
|
||
| | Binding | Exact Validation | | ||
| |---|---| | ||
| | Rust | `nemo_relay::plugin::dynamic::validate_exact(config)` | | ||
| | Python | `plugin.validate_exact(config)` | | ||
| | Node.js | `plugin.validateExact(config)` | | ||
| | Go | `ValidateExact(config)` | | ||
| | C | `nemo_relay_plugin_validate_exact` | | ||
|
|
||
| Both forms return `PluginHostReport`. Read `diagnostics` and | ||
| `runtime_diagnostics` under `config` instead of at the top level. | ||
| Check `dynamic_plugins` separately for errors in manifests, version rules, | ||
| file integrity, environments, signatures, and policy. Exact validation does | ||
| not check dynamic plugins. | ||
|
|
||
| ### Review Layered Dynamic Plugin Declarations | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| When the explicit-or-user and system `plugins.toml` files declare dynamic | ||
| records with the same manifest plugin ID, the higher-precedence record now | ||
| replaces the lower-precedence record. Relay no longer fails with a duplicate-ID | ||
| error, and it does not merge the lower record's `config` into the effective | ||
| plugin. This allows layered configuration, but a needed lower-precedence | ||
| setting can no longer take effect by itself. | ||
| </Warning> | ||
|
|
||
| If a system deployment repeats a user's dynamic-plugin ID, copy every setting | ||
| needed at runtime into the system record. The system manifest reference and its | ||
| lifecycle state also become authoritative. This applies to CLI gateway, | ||
| wrapper, persistent gateway, daemon broker, and every binding that uses the | ||
| normal `initialize(config, path)` API. | ||
|
|
||
| #### Python-Specific Errors | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| Python plugin APIs use more specific error types so applications can tell an | ||
| invalid setting from a missing file. Code that only catches `RuntimeError` can | ||
| miss these failures after the upgrade. | ||
| </Warning> | ||
|
|
||
| `nemo_relay.plugin.initialize()` and `nemo_relay.plugin.activate()` now raise | ||
| `ValueError` for invalid static settings. They raise `FileNotFoundError` when | ||
| a referenced configuration or resource is unavailable. Earlier releases | ||
| reported these failures as `RuntimeError`. | ||
|
|
||
| Update your exception handlers for these errors. Keep `RuntimeError` handling | ||
| for failures to acquire the plugin host or register a plugin. To inspect | ||
| static settings without starting plugins, use `validate` or `validate_exact`. | ||
|
|
||
| ### Verify Dynamic-Plugin Trust | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| Dynamic plugins now go through trust checks in every embedding API. By default, | ||
| Relay requires a signature, so an unsigned plugin that started on 0.8 can fail | ||
| to start on 0.9. Choose and validate a trust policy before deployment. | ||
| </Warning> | ||
|
|
||
| The core host now checks dynamic-plugin attestation through every embedding | ||
| API. Attestation checks the plugin artifact against the configured trust | ||
| policy. In 0.8, only CLI lifecycle commands enforced this policy. | ||
|
|
||
| If `[plugins.policy.defaults]` omits the policy fields, Relay uses | ||
| `startup = "required"` and `attestation = "signature_required"`. | ||
| An unsigned plugin that started on 0.8 can therefore fail to start on 0.9. | ||
|
|
||
| Choose a trust policy before you deploy: | ||
|
|
||
| - Sign the artifact and configure `trusted_public_keys` to use the default | ||
| signature requirement. | ||
| - If your trust policy permits it, explicitly set `attestation` to | ||
| `"integrity_only"` or `"signature_if_present"` under | ||
| `[plugins.policy.defaults]`. | ||
|
|
||
| Use `nemo-relay plugins validate <plugin-id>` and your embedding's `validate` | ||
| API to check the chosen policy and artifact before deployment. | ||
|
|
||
| Embedding `validate` calls return a report for every lifecycle-selected plugin, | ||
| including a plugin with a trust failure. They do not raise for that failure. | ||
| Check the matching `dynamic_plugins` entry's `status.integrity`, | ||
| `status.authenticity`, and `failure` before deployment. A failed trust report | ||
| has `selected = false` because Relay does not activate that plugin. With | ||
| `startup = "required"`, `initialize` rejects the same failure before it loads | ||
| plugin code. | ||
|
|
||
| `integrity_only` skips signature checks. It still requires a valid | ||
| `source.artifact` and a matching `integrity.sha256` digest. | ||
|
|
||
| ### Choose Trace Boundaries Explicitly | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| Propagation now keeps the Relay root by default so related work stays in one | ||
| trace. This changes which events share a trace and changes the meaning of the | ||
| exported ATIF `session_id`. | ||
| </Warning> | ||
|
|
||
| Default propagation capture and scope-stack forks now keep the Relay root | ||
| when one is available. This root identifies the trace shared by related work. | ||
| When you import a context with a root, work continues in the parent's | ||
| OpenTelemetry trace. Without a propagated root, the first local Agent scope | ||
| creates one. | ||
|
|
||
| To start a separate trace in the receiver, use the rootless capture API for | ||
| your binding: | ||
|
|
||
| | Binding | Rootless Capture | | ||
| |---|---| | ||
| | Rust | `capture_rootless_propagation_context()` | | ||
| | Python | `nemo_relay.capture_rootless_propagation_context()` | | ||
| | Node.js | `captureRootlessPropagationContext()` | | ||
| | Go | `CaptureRootlessPropagationContext()` | | ||
| | C | `nemo_relay_capture_rootless_propagation_context_json` | | ||
|
|
||
| A rootless context still links Relay events to their immediate parent. | ||
| The receiver's first local Agent scope creates a new root. Use explicit root | ||
| capture when your application supplies a stable run UUID. Authenticate the | ||
| source of an incoming context before you trust and import it. For details, refer to | ||
| [Scope Concepts](/about-nemo-relay/concepts/scopes). | ||
|
|
||
| In ATIF, use `trajectory_id` as the unique ID for each exported trajectory. | ||
| The exported `session_id` now uses the propagated root when one is present. | ||
| Several trajectories can share this ID. Update data joins or rules that | ||
| assume `session_id` and `trajectory_id` are the same. | ||
|
|
||
| Filenames, remote storage keys, and remote session headers still use the | ||
| trajectory scope UUID. The historical `{session_id}` filename placeholder | ||
| also uses that UUID. For details, refer to | ||
| [Run-Scoped Session IDs](/configure-plugins/observability/atif#run-scoped-session-ids). | ||
|
|
||
| ### Secure Trace Export and Review Tool Content | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| All `full`, `gen_ai`, and `openinference` trace endpoints require HTTPS for | ||
| remote collectors, with either HTTP or gRPC transport. Plain HTTP works only | ||
| with localhost and loopback IP addresses. OTLP/HTTP trace exporters no longer | ||
| follow redirects, even between HTTPS endpoints. This keeps trace data from | ||
| being sent to an insecure or unexpected destination. | ||
| </Warning> | ||
|
|
||
| Replace remote `http://` trace endpoints with the collector's final `https://` | ||
| URL, or use a loopback collector. Do not use an endpoint that requires a | ||
| redirect. These rules apply to plugin-managed endpoints and direct | ||
| subscribers, even when you redact the data. | ||
|
|
||
| Log and metric exporters keep their existing transport rules. The redirect | ||
| change does not apply to gRPC. | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| The `gen_ai` output now includes sanitized tool arguments, successful tool | ||
| results, and tool definitions. This gives collectors more useful trace data, | ||
| but it can also send tool content that they did not receive before. Review | ||
| collector access and redaction settings before you upgrade. | ||
| </Warning> | ||
|
|
||
| The `gen_ai` output format adds the following fields after sanitization: | ||
|
|
||
| | Field | Content | | ||
| |---|---| | ||
| | `gen_ai.tool.call.arguments` | Tool arguments that are JSON objects | | ||
| | `gen_ai.tool.call.result` | Successful tool results that are JSON objects | | ||
| | `gen_ai.tool.definitions` | Tool-definition identities | | ||
|
|
||
| Review who can access your collector and how you redact data before upgrading. | ||
| Setting `enable_full_payloads = false` does not disable tool-content export. | ||
| It controls how much LLM request history is kept. Use event sanitizers or | ||
| the PII `trajectory_context` preset to remove opaque tool payloads. These are | ||
| payloads whose structure Relay cannot safely interpret. For details, refer to | ||
| [GenAI Projection](/configure-plugins/observability/opentelemetry#genai-projection). | ||
|
|
||
| Direct subscribers can now read header values from environment variables | ||
| through `header_env`, or `headerEnv` in Node.js. Set each variable before | ||
| creating the subscriber. Creation fails if a referenced variable is unset, | ||
| empty, or contains only whitespace. Values with leading or trailing whitespace | ||
| also cause failure. Create a new subscriber to use a changed value. | ||
| Do not define the same header in both `headers` and `header_env`. Relay ignores | ||
| ASCII case when it compares header names. For details, refer to | ||
| [Direct Subscribers](/configure-plugins/observability/opentelemetry#direct-subscribers). | ||
|
|
||
| ### Configure Rotating Exporter Headers | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| Rust observability configuration structs now include `header_file`. Rust code | ||
| that uses a struct literal must set this field, usually to an empty map. Go code | ||
| that uses an unkeyed composite literal must use keyed fields instead. Also, | ||
| remote exporters with any header source must use HTTPS or WSS, except on | ||
| localhost or a loopback IP address. These changes keep rotated credentials from | ||
| being sent to an insecure or redirected destination. | ||
| </Warning> | ||
|
|
||
| Use `header_file` when a separate process writes a complete credential to a | ||
| file, such as a projected token file. Relay reads it for every HTTP delivery. | ||
| For ATOF, HTTP POST reads it for each event, WebSocket reads it when it connects | ||
| or reconnects, and NDJSON reads it when the sink starts. Use it for ATOF | ||
| streams, ATIF HTTP storage, and OpenTelemetry trace, log, and metric exporters. | ||
|
|
||
| For Rust struct literals, add an empty `HashMap` when you do not use file-based | ||
| headers. For Go, change an unkeyed literal to a keyed literal and omit | ||
| `HeaderFile` unless you need it. Keep each header name in only one of | ||
| `headers`, `header_env`, and `header_file`. | ||
|
|
||
| For a remote endpoint with configured headers, replace `http://` with the | ||
| collector's final `https://` URL. Use `wss://` for a remote ATOF WebSocket | ||
| destination. Relay does not follow redirects when headers are set. For details, | ||
| refer to [OpenTelemetry Exporter Headers](/configure-plugins/observability/opentelemetry#trace-endpoint-fields), | ||
| [ATIF HTTP Storage](/configure-plugins/observability/atif#http-endpoint-storage), and | ||
| [ATOF Streaming](/configure-plugins/observability/atof#stream-sinks). | ||
|
|
||
| ### Review Trajectory Redaction and Metric Dimensions | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| The `trajectory_context` preset now removes more opaque data and metric | ||
| attributes to limit data exposure. Dashboards or data jobs that use those | ||
| fields need to change. | ||
| </Warning> | ||
|
|
||
| The PII `trajectory_context` preset now removes opaque payloads and unknown | ||
| fields. It builds minimal provider payloads from recognized, sanitized | ||
| annotations in Relay's standard format. Runtime and opaque codecs produce | ||
| empty objects. | ||
|
|
||
| Application IDs are replaced with the same redaction marker. Use Relay | ||
| lifecycle IDs to link related events. | ||
|
|
||
| Typed metrics keep their required measurements. Their attributes are dropped | ||
| unless an exact string name and value match `metric_string_attribute_allowlist`. | ||
| The preset also drops numeric and boolean attributes. Add only fixed values | ||
| or values from a limited list that your dashboards need. A string array is | ||
| kept only if every value is allowed. | ||
|
|
||
| Set `builtin.preset = "trajectory_context"` before using | ||
| `metric_string_attribute_allowlist` or `custom_mark_payload_policy`. | ||
| Do not combine `builtin.preset` with `action`, `detector`, `pattern`, | ||
| `target_paths`, `target_path_globs`, `mask_char`, `unmasked_prefix`, or | ||
| `unmasked_suffix` in the same `builtin` settings. | ||
|
|
||
| Review code that reads opaque custom-mark payloads, routing metadata, or | ||
| detailed records of how prices were determined. The stricter preset removes | ||
| these fields by default. For details, | ||
| refer to [Trajectory Context Preset](/configure-plugins/pii-redaction/configuration#trajectory-context-preset). | ||
|
|
||
| ### Update Rust Cache Configuration | ||
|
|
||
| <Warning title="Breaking Change"> | ||
| The Rust response-cache API now uses an enum instead of a string so cache key | ||
| choices are checked at compile time. Existing Rust source that assigns a string | ||
| or uses the removed constant no longer builds. | ||
| </Warning> | ||
|
|
||
| `ResponseCacheConfig.key_strategy` is now a `ResponseCacheKeyStrategy` enum. | ||
| Replace string assignments and the removed `KEY_STRATEGY_EXACT_REQUEST` | ||
| constant with `ResponseCacheKeyStrategy::ExactRequest` or | ||
| `ResponseCacheKeyStrategy::Logical`. Import the enum from `nemo_relay_adaptive`. | ||
|
|
||
| Existing TOML and JSON `"exact_request"` values remain valid. The `"logical"` | ||
| strategy uses a separate set of cache keys. It ignores tool descriptions and | ||
| tool order. Use it only if you want requests with those differences to share | ||
| cached results. | ||
|
|
||
| ### Align Coding-Agent Versions and Deployment Modes | ||
|
|
||
| Upgrade OpenClaw to 2026.9.3 before installing the 0.9 Relay OpenClaw plugin. | ||
| The plugin's minimum gateway version is now 2026.9.3. | ||
|
|
||
| For new Pi integrations, use Pi 0.84.x and install one Relay extension copy. | ||
| Relay accepts later minor versions but marks them as unverified. Check that | ||
| hooks still work after an upgrade. | ||
|
|
||
| Personal extension installs and daemon bundles managed by an administrator | ||
| use different setup steps. Follow [Pi](/nemo-relay-cli/pi) or | ||
| [Daemon](/daemon/about) for your deployment mode. | ||
|
|
||
| Managed daemons require system-owned settings and a route credential for each | ||
| user on each computer. They also need persistent WebSocket control connections. | ||
| For remote deployments, use HTTPS and ensure that the daemon can reach client | ||
| workers. Set reverse proxies to pass WebSocket upgrades and ping/pong traffic | ||
| under `/_nemo-relay/control/`. | ||
|
|
||
| Confirm that worker plugins enforce policy or produce exporter output. | ||
| If a worker fails to start, an authenticated route can enter pass-through | ||
| mode and forward requests without those plugins. For details, refer to | ||
| [Daemon Operations](/daemon/operations) and | ||
| [Reverse Proxy Configuration](/daemon/reference#configure-a-trusted-reverse-proxy). | ||

| Use this page to plan an upgrade to NeMo Relay 0.10. It will collect required | |
| upgrade actions as they are identified during the 0.10 development cycle. | |
| If you skip releases, read each release's migration guide and release notes | |
| in order. | |
| ## Upgrade to NeMo Relay 0.10 | |
| ## Upgrade to NeMo Relay 0.9 | |
| ### Refresh Relay-Managed Coding-Agent Integrations | |
| After upgrading the CLI, refresh personal Relay-managed integrations before | |
| starting new sessions: | |
| ```bash | |
| nemo-relay integrations refresh | |
| ``` | |
| To repair only Codex, use `nemo-relay install codex --force`. It can repair | |
| Relay-owned marketplace entries that point to missing files. These commands | |
| apply to personal integrations. | |
| For daemon bundles managed by an administrator, follow the | |
| [daemon upgrade workflow](/daemon/operations#upgrade-and-roll-back). Close | |
| sessions and let workers finish pending requests. Then stop the service and | |
| replace the binary at the same path. Keep the saved identity state and | |
| existing bundle files. | |
| ### Pass Tool Execution Context to Intercepts | |
| <Warning title="Breaking Change"> | |
| Tool callbacks use a context object because Relay now provides the optional | |
| provider tool-call ID with the tool name and arguments. Existing callbacks no | |
| longer match the public API and must be updated. | |
| </Warning> | |
| Tool execution intercepts now receive `ToolExecutionContext` and a | |
| continuation. The context holds the tool name, arguments, and optional | |
| provider-issued tool-call ID. The continuation calls the next intercept or | |
| the tool itself. | |
| Change Rust, Python, and Go callbacks from `(tool_name, args, next)` to | |
| `(context, next)`. For Node.js and public C callbacks, replace the argument | |
| payload with the context. Pass the context's arguments to the continuation. | |
| Read the name and call ID from the context. Node.js uses `toolName`, `args`, | |
| and `toolCallId`. Public C callbacks receive `tool_name`, `args`, and | |
| `tool_call_id` in `context_json`. | |
| Native and worker plugins that register this callback must exclude Relay 0.8 | |
| from their supported version range. Set `compat.relay = ">=0.9,<1.0"` or | |
| another range that meets this rule. Native plugins use version 5 of the | |
| application binary interface (ABI) for this callback. For binding details and examples, refer to | |
| [Tool Execution Context](/reference/tool-execution-intercept-outcomes#tool-execution-context). | |
| ### Retain the Plugin Host Activation | |
| <Warning title="Breaking Change"> | |
| NeMo Relay 0.9 uses one plugin host to control when plugins start and stop. Global clear and report functions and | |
| explicit dynamic activation-spec APIs are removed. Update startup, report | |
| handling, and shutdown together in each application that hosts plugins. | |
| </Warning> | |
| `initialize` now returns a `PluginHostActivation` handle for static and dynamic | |
| plugins. This handle keeps the plugins active. Keep it for as long as your | |
| application needs them. | |
| A process can have only one active handle. Close it before starting another. | |
| If close fails, keep the handle and try closing it again. | |
| Use the following APIs to manage the handle in each binding: | |
| | Binding | Initialize | Read the Report | Close | | |
| |---|---|---|---| | |
| | Rust | `nemo_relay::plugin::dynamic::initialize(config, path).await?` | `activation.report()` | `activation.close()?` | | |
| | Python | `await plugin.initialize(config, path)` | `activation.report` | `await activation.close()` | | |
| | Node.js | `await plugin.initialize(config, path)` | `activation.report` | `await activation.close()` | | |
| | Go | `Initialize(config, path)` | `activation.Report()` | `activation.Close()` | | |
| | C | `nemo_relay_plugin_initialize` | `nemo_relay_plugin_host_activation_report_json` | `nemo_relay_plugin_host_activation_close` | | |
| Replace global clear calls with the handle's close operation. This includes | |
| Python `clear()` and `clear_async()`, Node.js `clear()`, Rust | |
| `clear_plugin_configuration()`, and the matching Go and C calls. Read reports | |
| from the handle instead of a global report function. | |
| Apply the following cleanup rules for your binding: | |
| - In Python, use `async with plugin.activate(config, path)` to close the handle | |
| when the block ends. | |
| - In Node.js, call `await relay.flushSubscribers()` before closing the handle. | |
| This lets queued subscribers finish. For existing dynamic-plugin handles, | |
| replace the `active` property with `isActive`. | |
| - In C, inspect the report after closing the handle. Then release the handle | |
| with `nemo_relay_plugin_host_activation_free`. | |
| Replace explicit dynamic-plugin setup with file-based setup: | |
| 1. Move `DynamicPluginActivationSpec` entries to `[[plugins.dynamic]]` records | |
| in `plugins.toml`. | |
| 2. Replace `initialize_with_dynamic_plugins` or `initializeWithDynamicPlugins` | |
| with `initialize`, and pass the file as its optional path. | |
| 3. Remove calls to Python `load_dynamic_plugin_activation_specs`. The host now | |
| reads those records from the file. | |
| In Rust, replace `initialize_plugins` with | |
| `nemo_relay::plugin::dynamic::initialize`. | |
| For complete examples, refer to | |
| [Configure and Initialize Plugins](/configure-plugins/initialize-plugins). | |
| For dynamic-plugin records, refer to | |
| [Configure Discoverable Plugins](/configure-plugins/discoverable-plugins). | |
| ### Validate the Effective Plugin Configuration | |
| `validate` now checks the same settings, dynamic manifests, version rules, and | |
| trust policy as `initialize`. It does not load plugin code. | |
| If you pass a `plugins.toml` path, Relay uses it instead of searching for a | |
| user file. Relay then merges the system file and applies settings from your | |
| application code. Check `config_paths` and the redacted `resolved_config` in | |
| the report to confirm which settings Relay used. | |
| Use exact validation to check only a complete static document in memory. | |
| It does not read files. Choose the API for your binding: | |
| | Binding | Exact Validation | | |
| |---|---| | |
| | Rust | `nemo_relay::plugin::dynamic::validate_exact(config)` | | |
| | Python | `plugin.validate_exact(config)` | | |
| | Node.js | `plugin.validateExact(config)` | | |
| | Go | `ValidateExact(config)` | | |
| | C | `nemo_relay_plugin_validate_exact` | | |
| Both forms return `PluginHostReport`. Read `diagnostics` and | |
| `runtime_diagnostics` under `config` instead of at the top level. | |
| Check `dynamic_plugins` separately for errors in manifests, version rules, | |
| file integrity, environments, signatures, and policy. Exact validation does | |
| not check dynamic plugins. | |
| ### Review Layered Dynamic Plugin Declarations | |
| <Warning title="Breaking Change"> | |
| When the explicit-or-user and system `plugins.toml` files declare dynamic | |
| records with the same manifest plugin ID, the higher-precedence record now | |
| replaces the lower-precedence record. Relay no longer fails with a duplicate-ID | |
| error, and it does not merge the lower record's `config` into the effective | |
| plugin. This allows layered configuration, but a needed lower-precedence | |
| setting can no longer take effect by itself. | |
| </Warning> | |
| If a system deployment repeats a user's dynamic-plugin ID, copy every setting | |
| needed at runtime into the system record. The system manifest reference and its | |
| lifecycle state also become authoritative. This applies to CLI gateway, | |
| wrapper, persistent gateway, daemon broker, and every binding that uses the | |
| normal `initialize(config, path)` API. | |
| #### Python-Specific Errors | |
| <Warning title="Breaking Change"> | |
| Python plugin APIs use more specific error types so applications can tell an | |
| invalid setting from a missing file. Code that only catches `RuntimeError` can | |
| miss these failures after the upgrade. | |
| </Warning> | |
| `nemo_relay.plugin.initialize()` and `nemo_relay.plugin.activate()` now raise | |
| `ValueError` for invalid static settings. They raise `FileNotFoundError` when | |
| a referenced configuration or resource is unavailable. Earlier releases | |
| reported these failures as `RuntimeError`. | |
| Update your exception handlers for these errors. Keep `RuntimeError` handling | |
| for failures to acquire the plugin host or register a plugin. To inspect | |
| static settings without starting plugins, use `validate` or `validate_exact`. | |
| ### Verify Dynamic-Plugin Trust | |
| <Warning title="Breaking Change"> | |
| Dynamic plugins now go through trust checks in every embedding API. By default, | |
| Relay requires a signature, so an unsigned plugin that started on 0.8 can fail | |
| to start on 0.9. Choose and validate a trust policy before deployment. | |
| </Warning> | |
| The core host now checks dynamic-plugin attestation through every embedding | |
| API. Attestation checks the plugin artifact against the configured trust | |
| policy. In 0.8, only CLI lifecycle commands enforced this policy. | |
| If `[plugins.policy.defaults]` omits the policy fields, Relay uses | |
| `startup = "required"` and `attestation = "signature_required"`. | |
| An unsigned plugin that started on 0.8 can therefore fail to start on 0.9. | |
| Choose a trust policy before you deploy: | |
| - Sign the artifact and configure `trusted_public_keys` to use the default | |
| signature requirement. | |
| - If your trust policy permits it, explicitly set `attestation` to | |
| `"integrity_only"` or `"signature_if_present"` under | |
| `[plugins.policy.defaults]`. | |
| Use `nemo-relay plugins validate <plugin-id>` and your embedding's `validate` | |
| API to check the chosen policy and artifact before deployment. | |
| Embedding `validate` calls return a report for every lifecycle-selected plugin, | |
| including a plugin with a trust failure. They do not raise for that failure. | |
| Check the matching `dynamic_plugins` entry's `status.integrity`, | |
| `status.authenticity`, and `failure` before deployment. A failed trust report | |
| has `selected = false` because Relay does not activate that plugin. With | |
| `startup = "required"`, `initialize` rejects the same failure before it loads | |
| plugin code. | |
| `integrity_only` skips signature checks. It still requires a valid | |
| `source.artifact` and a matching `integrity.sha256` digest. | |
| ### Choose Trace Boundaries Explicitly | |
| <Warning title="Breaking Change"> | |
| Propagation now keeps the Relay root by default so related work stays in one | |
| trace. This changes which events share a trace and changes the meaning of the | |
| exported ATIF `session_id`. | |
| </Warning> | |
| Default propagation capture and scope-stack forks now keep the Relay root | |
| when one is available. This root identifies the trace shared by related work. | |
| When you import a context with a root, work continues in the parent's | |
| OpenTelemetry trace. Without a propagated root, the first local Agent scope | |
| creates one. | |
| To start a separate trace in the receiver, use the rootless capture API for | |
| your binding: | |
| | Binding | Rootless Capture | | |
| |---|---| | |
| | Rust | `capture_rootless_propagation_context()` | | |
| | Python | `nemo_relay.capture_rootless_propagation_context()` | | |
| | Node.js | `captureRootlessPropagationContext()` | | |
| | Go | `CaptureRootlessPropagationContext()` | | |
| | C | `nemo_relay_capture_rootless_propagation_context_json` | | |
| A rootless context still links Relay events to their immediate parent. | |
| The receiver's first local Agent scope creates a new root. Use explicit root | |
| capture when your application supplies a stable run UUID. Authenticate the | |
| source of an incoming context before you trust and import it. For details, refer to | |
| [Scope Concepts](/about-nemo-relay/concepts/scopes). | |
| In ATIF, use `trajectory_id` as the unique ID for each exported trajectory. | |
| The exported `session_id` now uses the propagated root when one is present. | |
| Several trajectories can share this ID. Update data joins or rules that | |
| assume `session_id` and `trajectory_id` are the same. | |
| Filenames, remote storage keys, and remote session headers still use the | |
| trajectory scope UUID. The historical `{session_id}` filename placeholder | |
| also uses that UUID. For details, refer to | |
| [Run-Scoped Session IDs](/configure-plugins/observability/atif#run-scoped-session-ids). | |
| ### Secure Trace Export and Review Tool Content | |
| <Warning title="Breaking Change"> | |
| All `full`, `gen_ai`, and `openinference` trace endpoints require HTTPS for | |
| remote collectors, with either HTTP or gRPC transport. Plain HTTP works only | |
| with localhost and loopback IP addresses. OTLP/HTTP trace exporters no longer | |
| follow redirects, even between HTTPS endpoints. This keeps trace data from | |
| being sent to an insecure or unexpected destination. | |
| </Warning> | |
| Replace remote `http://` trace endpoints with the collector's final `https://` | |
| URL, or use a loopback collector. Do not use an endpoint that requires a | |
| redirect. These rules apply to plugin-managed endpoints and direct | |
| subscribers, even when you redact the data. | |
| Log and metric exporters keep their existing transport rules. The redirect | |
| change does not apply to gRPC. | |
| <Warning title="Breaking Change"> | |
| The `gen_ai` output now includes sanitized tool arguments, successful tool | |
| results, and tool definitions. This gives collectors more useful trace data, | |
| but it can also send tool content that they did not receive before. Review | |
| collector access and redaction settings before you upgrade. | |
| </Warning> | |
| The `gen_ai` output format adds the following fields after sanitization: | |
| | Field | Content | | |
| |---|---| | |
| | `gen_ai.tool.call.arguments` | Tool arguments that are JSON objects | | |
| | `gen_ai.tool.call.result` | Successful tool results that are JSON objects | | |
| | `gen_ai.tool.definitions` | Tool-definition identities | | |
| Review who can access your collector and how you redact data before upgrading. | |
| Setting `enable_full_payloads = false` does not disable tool-content export. | |
| It controls how much LLM request history is kept. Use event sanitizers or | |
| the PII `trajectory_context` preset to remove opaque tool payloads. These are | |
| payloads whose structure Relay cannot safely interpret. For details, refer to | |
| [GenAI Projection](/configure-plugins/observability/opentelemetry#genai-projection). | |
| Direct subscribers can now read header values from environment variables | |
| through `header_env`, or `headerEnv` in Node.js. Set each variable before | |
| creating the subscriber. Creation fails if a referenced variable is unset, | |
| empty, or contains only whitespace. Values with leading or trailing whitespace | |
| also cause failure. Create a new subscriber to use a changed value. | |
| Do not define the same header in both `headers` and `header_env`. Relay ignores | |
| ASCII case when it compares header names. For details, refer to | |
| [Direct Subscribers](/configure-plugins/observability/opentelemetry#direct-subscribers). | |
| ### Configure Rotating Exporter Headers | |
| <Warning title="Breaking Change"> | |
| Rust observability configuration structs now include `header_file`. Rust code | |
| that uses a struct literal must set this field, usually to an empty map. Go code | |
| that uses an unkeyed composite literal must use keyed fields instead. Also, | |
| remote exporters with any header source must use HTTPS or WSS, except on | |
| localhost or a loopback IP address. These changes keep rotated credentials from | |
| being sent to an insecure or redirected destination. | |
| </Warning> | |
| Use `header_file` when a separate process writes a complete credential to a | |
| file, such as a projected token file. Relay reads it for every HTTP delivery. | |
| For ATOF, HTTP POST reads it for each event, WebSocket reads it when it connects | |
| or reconnects, and NDJSON reads it when the sink starts. Use it for ATOF | |
| streams, ATIF HTTP storage, and OpenTelemetry trace, log, and metric exporters. | |
| For Rust struct literals, add an empty `HashMap` when you do not use file-based | |
| headers. For Go, change an unkeyed literal to a keyed literal and omit | |
| `HeaderFile` unless you need it. Keep each header name in only one of | |
| `headers`, `header_env`, and `header_file`. | |
| For a remote endpoint with configured headers, replace `http://` with the | |
| collector's final `https://` URL. Use `wss://` for a remote ATOF WebSocket | |
| destination. Relay does not follow redirects when headers are set. For details, | |
| refer to [OpenTelemetry Exporter Headers](/configure-plugins/observability/opentelemetry#trace-endpoint-fields), | |
| [ATIF HTTP Storage](/configure-plugins/observability/atif#http-endpoint-storage), and | |
| [ATOF Streaming](/configure-plugins/observability/atof#stream-sinks). | |
| ### Review Trajectory Redaction and Metric Dimensions | |
| <Warning title="Breaking Change"> | |
| The `trajectory_context` preset now removes more opaque data and metric | |
| attributes to limit data exposure. Dashboards or data jobs that use those | |
| fields need to change. | |
| </Warning> | |
| The PII `trajectory_context` preset now removes opaque payloads and unknown | |
| fields. It builds minimal provider payloads from recognized, sanitized | |
| annotations in Relay's standard format. Runtime and opaque codecs produce | |
| empty objects. | |
| Application IDs are replaced with the same redaction marker. Use Relay | |
| lifecycle IDs to link related events. | |
| Typed metrics keep their required measurements. Their attributes are dropped | |
| unless an exact string name and value match `metric_string_attribute_allowlist`. | |
| The preset also drops numeric and boolean attributes. Add only fixed values | |
| or values from a limited list that your dashboards need. A string array is | |
| kept only if every value is allowed. | |
| Set `builtin.preset = "trajectory_context"` before using | |
| `metric_string_attribute_allowlist` or `custom_mark_payload_policy`. | |
| Do not combine `builtin.preset` with `action`, `detector`, `pattern`, | |
| `target_paths`, `target_path_globs`, `mask_char`, `unmasked_prefix`, or | |
| `unmasked_suffix` in the same `builtin` settings. | |
| Review code that reads opaque custom-mark payloads, routing metadata, or | |
| detailed records of how prices were determined. The stricter preset removes | |
| these fields by default. For details, | |
| refer to [Trajectory Context Preset](/configure-plugins/pii-redaction/configuration#trajectory-context-preset). | |
| ### Update Rust Cache Configuration | |
| <Warning title="Breaking Change"> | |
| The Rust response-cache API now uses an enum instead of a string so cache key | |
| choices are checked at compile time. Existing Rust source that assigns a string | |
| or uses the removed constant no longer builds. | |
| </Warning> | |
| `ResponseCacheConfig.key_strategy` is now a `ResponseCacheKeyStrategy` enum. | |
| Replace string assignments and the removed `KEY_STRATEGY_EXACT_REQUEST` | |
| constant with `ResponseCacheKeyStrategy::ExactRequest` or | |
| `ResponseCacheKeyStrategy::Logical`. Import the enum from `nemo_relay_adaptive`. | |
| Existing TOML and JSON `"exact_request"` values remain valid. The `"logical"` | |
| strategy uses a separate set of cache keys. It ignores tool descriptions and | |
| tool order. Use it only if you want requests with those differences to share | |
| cached results. | |
| ### Align Coding-Agent Versions and Deployment Modes | |
| Upgrade OpenClaw to 2026.9.3 before installing the 0.9 Relay OpenClaw plugin. | |
| The plugin's minimum gateway version is now 2026.9.3. | |
| For new Pi integrations, use Pi 0.84.x and install one Relay extension copy. | |
| Relay accepts later minor versions but marks them as unverified. Check that | |
| hooks still work after an upgrade. | |
| Personal extension installs and daemon bundles managed by an administrator | |

Validate all replacements before writing any manifest.
The current manifests match each pattern exactly once. However, replace_one writes each file immediately, and set_example_package_versions invokes it sequentially. If a later pattern fails, earlier version updates remain in the working tree. Validate all replacements first, then write the files.

Use an invocation-specific gateway port.
Both E2E scripts bind relay to 127.0.0.1:47632. When the scripts run concurrently, one relay process cannot bind the port and its test fails.
scripts/test-claude-plugin-e2e.sh#L59-L59: allocate or receive a unique port and use it for relay configuration and assertions.scripts/test-codex-plugin-e2e.sh#L115-L115: use the same per-invocation allocation strategy.
As per path instructions, automation changes must preserve reproducibility.

Overview
Extend
promote_resource_metadata_prefixesfrom traces to OTLP logs and metrics so all three signals can project root-scope metadata into their OpenTelemetryResource.Details
promote_resource_metadata_prefixesto explicit log and metric endpoint configuration. Derived log and metric endpoints inherit the trace endpoint's prefixes.Behavioral and compatibility changes:
service_name,service_namespace,service_version, andresource_attributescontinue to win over promoted metadata with the same key.OpenTelemetrySignalEndpointConfigstruct is source-breaking for downstream Rust callers that construct it with exhaustive literals. Serde-based TOML and JSON configuration remains backward compatible.Validation:

Start with the shared promotion and lineage behavior in
crates/core/src/observability/otel_signal.rs, then review provider selection inotel_logs.rsandotel_metrics.rs. The export-level log-and-metric inheritance test incrates/core/tests/unit/observability/otel_metrics_tests.rsdemonstrates configured precedence and child-scope routing.Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to)
