fix(usage): say resets momentarily in the final minute

[extoci]

Problem

During the final minute before a usage window resets, the label says resets in 0m even though the reset has not happened. This makes the allowance look ready early.

Change

Show Resets momentarily for positive durations below one minute. The shared formatter covers web, desktop, and mobile account rows. Mobile's pooled refill label now uses that formatter too.

Time until reset	Before	After
2 hours	resets in 2h 0m	resets in 2h 0m
1 minute	resets in 1m	resets in 1m
45 seconds	resets in 0m	Resets momentarily
1 second	resets in 0m	Resets momentarily
Reset reached	resets now	resets now

Scope and approval

Refs #16973 for the misleading final-minute wording. This is a small, focused correction to an obvious labeling bug, limited to wording.

Verification

• vp test run packages/shared/src/usageLimits.test.ts: 46 tests passed after rebasing onto current main. The regression cases cover the one-minute boundary, positive sub-minute durations, exact and past reset times, and invalid timestamps.
• Targeted lint and formatting checks passed for all three changed files.
• Mobile tsc --noEmit passed.

Before/after evidence is the example table above, as requested. Browser and native visual verification were not performed.

Implemented with GPT-6.1-Sol in the Codex harness.

Approvability

Verdict: Approved at ed5de7f

Macroscope's review found this PR approvable — This is a narrowly scoped usage-label correction: positive sub-minute resets now say they are momentary, while existing reset behavior remains unchanged. The shared formatter and boundary tests cover the affected displays, with no schema, deployment, security, billing, or static-analysis impact.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.

📝 Walkthrough

📝 Walkthrough

Walkthrough

The shared reset formatter now distinguishes resets less than one minute away. The pooled usage screen uses this formatter for its next-refill label. Tests cover countdown boundaries and invalid reset timestamps.

Changes

Refill timing

Layer / File(s)	Summary
Format and display refill timing packages/shared/src/usageLimits.ts, packages/shared/src/usageLimits.test.ts, apps/mobile/src/features/usage/UsageLimitsPooled.tsx	formatResetsIn returns “Resets momentarily” for future resets less than one minute away. Tests cover countdown boundaries and invalid timestamps. The pooled usage screen uses the formatter on the refill member’s window and adjusts the label text.

Merge Risk: ⚪ Minimal · up to ed5de

Resets under one minute now display “Resets momentarily”; longer and completed resets retain their existing wording, and invalid timestamps do not show a misleading label. No actionable merge-blocking risk remains.

Review details

Systems and components

• observed — packages/shared (library) was modified; 2 changed files map to changed impact.
• observed — apps/mobile (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in apps/mobile/src/features/usage/UsageLimitsPooled.tsx: Removed the formatDuration import; refill timing no longer formats a duration calculated from nextRefill.at.
• observed — Modified behavior in apps/mobile/src/features/usage/UsageLimitsPooled.tsx: The next-refill text now formats the refill member’s window with formatResetsIn, replacing its “resets in ” prefix with “in ” and “resets now” with “now”; previously it displayed “now” when nextRefill.at <= now, otherwise a duration from the timestamp difference.
• observed — Modified behavior in packages/shared/src/usageLimits.ts: formatResetsIn adds a "Resets momentarily" result for future resets less than MINUTE away, while keeping "resets now" for reset times at or before now and the existing countdown for later resets.
• observed — Modified behavior in packages/shared/src/usageLimits.test.ts: Added parameterized reset-boundary expectations and an assertion that formatResetsIn produces the corresponding countdown or reset label.

Note

This comment is posted by Julius' dot

Closing because the changed usage labels have no before/after screenshots. The example table and formatter tests do not show the rendered web and mobile labels required by the verification policy. Add screenshots of the final-minute account and pooled-refill labels before and after this change, then request reconsideration.
