chore(template): clean-slate template snapshot from bb4a0c7

Curated, product-agnostic snapshot of the post-story-04 tree: demo
content deleted, auth-only reference feature, web-next shell, all gates
green. Product-specific docs, ADRs 027-029, PRDs/epics/archive, editor
library traces, and product naming are curated out; generic template
repairs (coverage provider devDeps, root test:coverage script, live
lint fixes, root-only release-please) are kept. See TEMPLATE.md for
provenance, curation list, and usage.

+## Filter: license
+
+<!-- Result: Apache-2.0 -->
+
+`npm view @opentelemetry/resources license` returns `Apache-2.0`. Apache-2.0 is on the allowlist.
+
+## Filter: types
+
+<!-- Result: native -->
+
+`@opentelemetry/resources` is authored in TypeScript and ships its own `.d.ts` declaration files. No separate `@types/` package is needed.
+
+## Filter: maintenance
+
+<!-- Result: active -->
+
+Actively maintained by the OpenTelemetry community. The 1.27.x line is on the stable 1.x track and receives regular releases. Stable versioning reflects the maturity of the resources specification.
+
+## Filter: boundary-fit
+
+<!-- Result: pass -->
+
+ADR-017 §8 restricts `@opentelemetry/resources` to `**/instrumentation/otel/**` and app init paths. The `Resource` class is used in `initOtelServerNode` to attach service name, version, and environment attributes to all telemetry signals. Feature packages never import it directly.
+
+## Filter: shadow-check
+
+<!-- Result: pass -->
+
+`@opentelemetry/resources` is the standard OTel resource detection package. No competing resource attribution mechanism is present in the workspace.
+
+## Filter: eu-residency
+
+<!-- Result: n/a -->
+
+`@opentelemetry/resources` is a pure configuration package that attaches static metadata to telemetry signals. It has no network communication or data transmission. EU residency does not apply.
+
+## Filter: cve-scan
+
+<!-- Result: clean -->
+
+`pnpm audit --audit-level=moderate` reports no advisories against `@opentelemetry/resources` at the time of this trace.
+
+## Filter: named-consumer
+
+<!-- Result: pass -->
+
+`packages/core-shared/src/instrumentation/otel/init-otel-server-node.ts` uses `Resource` to tag all OTel signals with `service.name`, `service.version`, and `deployment.environment` attributes, enabling filtering by service in Sentry and future backends.
+
+## Prompt: replaces
+
+Manual tag propagation that would otherwise require attaching service metadata to every span and log record individually. `Resource` is set once at SDK init time and propagates to all signals automatically.
+
+## Prompt: migration-cost-out
+
+Low. `@opentelemetry/resources` is used in one SDK init file. Removing it means losing automatic service metadata on signals — signals would still be emitted but lose `service.name` attribution unless manually added to each span.
+
+## Prompt: alternatives-considered
+
+1. **Manual span attributes** — Set `service.name` on every `startSpan()` call. Rejected: error-prone at scale; resources are a first-class OTel concept designed for this exact purpose.
+2. **Sentry release/environment config** — Sentry SDK accepts `release` and `environment` directly. Rejected: Sentry-specific; OTel Resource is the vendor-neutral mechanism that works with any exporter.
