Task brief

<!-- The orchestrator fills this in for every task. Reviewers check tier, runtime and model against model-policy.md and botgumi.config.ts. -->

• Issue: #n (labels track:*, tier:*, runtime:*; gate for human gates)
• Blocked by: #n, or none
• Track: backend | ios | android | landing | dashboard | design | docs
• Tier: high | mid | low
• Why this tier: one line
• Worker: runtime + model, for example claude · claude-sonnet-5-5
• Reviewers: one (mid, low) or both (high), each on a different runtime from the worker
• Branch: <track>/<topic>

#Goal

What is true when this is done, in one or two sentences.

#Inputs

• ADRs, contract paths, hi-fi screens, tracking-plan events this task touches.

#Out of scope

#Contract changes

None, or the change request and which tracks need a follow-up.

#Done when

• The track's CI passes, output pasted in How tested.
• Strings in en and zh-Hans. All four states handled.
• Docs: the module's pages updated if behaviour, a contract or a design changed; pnpm docs:check passes.
• No blocking review findings open; botgumi/review is success.
• Merge: by the orchestrator if merge-policy.md allows it, otherwise by a human.
