Explicit Identity Across Boundaries

Never rely on "latest" or "current" when crossing process or async boundaries.

Pattern

Pass explicit identifiers through the entire pipeline. "Most recent" is a race condition.

DO

• Pass --session-id $ID when spawning processes
• Store IDs in state files for later correlation
• Use full UUIDs, not partial matches
• Keep different ID types separate (don't collapse concepts)
