Error-Handling & Observability Audit + Fix Plan

Degree of freedom: HIGH — map silent paths, score, plan. Stay plan-only. No code or SDK edits until each phase is approved.

This skill vs neighbors

How to reason (every plan item)

1. Propose — report, init, redact, or wrap a silent path
2. Risk — what fails in prod with no signal (or PII leaving the env)
3. Keep-working — surfaces that already capture and sanitize
4. Phase — swallows → coverage → redaction → LLM traces (do not execute)
