Implementation Spec: Round 10 — COMPLETE

Goal

Auto-integration + ergonomics: rate-limit workers, auto-metrics on service calls — reduce manual wiring/boilerplate.

New Features

1. AutoMetricsServiceBuilder (mytheclipse-core, observability)

File: crates/mytheclipse/src/auto_metrics_service.rs

• Composes ServiceBuilder + MetricsCollector (+ MetricsBridge when resiliency)
• .run() auto-records: calls_total counter (labelled by outcome ok/err/timeout/ circuit_open/rate_limited) + duration histogram; emits bridge when attached
• Chainable .with_collector/.with_bridge/.with_builders
• 1 test

2. RateLimitedWorkerPool (mytheclipse-queue, in-memory)

File: crates/mytheclipse-queue/src/worker_rate_limited.rs

• Wraps WorkerPool with RateLimitedQueue — token-bucket back-pressured dequeue, prevents workers hammering upstream beyond rate limit
• new(queue, worker_cfg, rate_per_sec, burst) + start(topic, handler)
• 1 test (construction)

Files

• new: core/src/auto_metrics_service.rs, queue/src/worker_rate_limited.rs
• core/lib.rs: +module+export AutoMetricsServiceBuilder
• queue/lib.rs: +module+export RateLimitedWorkerPool (rewrote export block)

Build: exit 0. Tests: 0 FAILED (86 core pass). Clippy: 0 new warnings.
