role-proof-duration — Routing proof: format elapsed time

Plan: sha256:586c3bec4e9092d582c79d5f049e2fc01b8e62cd002daa2b1e4a0cee49d47a02
Cycle: 2026-W37
Priority: 0
Risk: low
Token ceiling: 150000

Goal

Prove Astra high Scout/Review and medium Implement using two independent sandboxed tasks and protected auto merge

Problem

acceptance/routing/duration.ts is an unimplemented fixture

Desired outcome

Implement formatDuration: null/nonfinite -> Unavailable, negative -> 0s; floor milliseconds to seconds; below60 -> Ns, below3600 -> Nm Ns, otherwise Nh Nm Ns with hours unbounded. Match the unchanged check-duration.ts cases.

Scope

• acceptance/routing/duration.ts

Non-goals

• Only edit the named implementation file. Do not change acceptance scripts, workflows, dependencies, or other code. Do not commit or push manually; Roc handles commits and PRs.

Acceptance criteria

• bun acceptance/routing/check-duration.ts passes unchanged

Validation

• bun acceptance/routing/check-duration.ts
• bunx --no-install biome check acceptance/routing/duration.ts

Dependencies

• None
