ADR-0002 step-aware retry: withRetry exists and is tested but never wired into the pipeline

[Alimedhat000]

Summary

withRetry (packages/worker/src/infrastructure/retry.ts) implements per-step retry classification per ADR-0002 and is unit-tested, but no production code calls it.

Evidence

• Only references to withRetry: infrastructure/retry.ts itself and test/unit/infrastructure/retry.test.ts.
• packages/worker/src/deployments/pipeline.ts has no retry logic; the only inline retry is the port-conflict loop in strategies/dockerfile.ts:23.

Scope

Wire withRetry into the pipeline steps per ADR-0002:

• git clone — retry on timeout, fail fast on auth errors (exit 128).
• npm install / build — retry on network blips, fail fast on 404 / non-zero build.

Or, if the classification isn't wanted, soften the ADR / resume wording instead.
