docs: add otel-scrape VRS by schickling-assistant · Pull Request #867 · overengineeringstudio/effect-utils

schickling-assistant · 2026-06-29T07:15:39Z

Problem

Build and development tools expose useful timing/profile data through tool-specific structured output, but effect-utils needed one public wrapper contract and source of truth for reusable build/dev telemetry.

Goal

Land the otel-scrape implementation and VRS as the effect-utils-owned process-wrapper telemetry substrate, while keeping privileged platform helper realization outside the public package.

Decisions

Implement otel-scrape in Rust with Nix/devenv integration.
Keep wrapper facts, OTLP span construction, adapter semantics, CAS profile links, and helper-stream protocol in effect-utils.
Reuse generated telemetry registry infrastructure as the shared SSOT across Rust and TypeScript.
Keep Rust CAS private to otel-scrape until there is a second Rust consumer or generated cross-language contract.
Treat exact process observation as capability-gated by backend and runner class.
Require Linux release exactness to use cgroup-scoped authority or an equivalently strong kernel-owned boundary.
Keep macOS ARM degraded by default until an Endpoint Security-style helper proves entitlement, approval, lifecycle, event-loss, and runner-class fixture behavior.

Verification

devenv tasks run check:all --no-tui --show-output passed in effect-utils on 2026-06-30.
Latest pushed effect-utils commit: e9888aae (docs: record definitive macos es probe).
macOS ARM runner-class probes validated SDK/toolchain availability and the degraded baseline. The definitive probe compiled and linked a minimal Endpoint Security client, but ordinary task execution returned ES_NEW_CLIENT_RESULT_ERR_NOT_PRIVILEGED, rejecting the unprivileged exact-wrapper path.
Focused Rust tests passed for helper-stream exact/degraded behavior, OTLP env vars, compression handling, nested wrapper ownership, CAS profile artifacts, and adapter records.
git diff --check passed.
Public leak scan over touched public docs found no private paths, machine identities, credentials, raw argv, raw output, or private topology.
Dotfiles helper rollout spec is tracked separately in draft PR schickling/dotfiles#1224.

Complexity

The public wrapper is intentionally split from privileged helper realization. The package can produce degraded telemetry everywhere today and exact helper-stream telemetry only when a validated platform helper supplies complete evidence.

Concerns

Linux and macOS exactness are not release claims yet. macOS is definitively narrowed to a signed/entitled Endpoint Security helper; the public wrapper must remain degraded without that helper.

Friction & bottlenecks

Dotfiles validation for the stacked helper spec hit unrelated generated-workflow and broad package-graph noise; the effect-utils gate itself passed.

Follow-ups

Prototype Linux cgroup-scoped helper realization.
Prototype signed/entitled macOS Endpoint Security helper realization, approval/supervision, loss handling, and runner-class validation.
Enable helper-stream dogfooding only behind helper health checks that can prove exact/degraded/unavailable state.

These rows had compatible baseline data, but their semantic impact rounded to 0.00x because the movement was below the configured budget, below the noise floor, or inside the robust noise band.
