chore(mobile): remove dead Kilo Pass tier-description helper

[iscekic]

Changelog for users

• No user-visible change: Kilo Pass tier cards still show " paid credits added monthly for Kilo App usage." in the active language.

Changelog for maintainers

• Delete the unused formatKiloPassTierDescription helper, a superseded copy of the tier-card formatting.
• Delete subscription-page-copy.test.ts, which exercised only the deleted helper.
• Remove the inert vi.mock('@/lib/kilo-pass/subscription-page-copy') block from the subscription-screen test.
• The subscription screen keeps its inline formatUsd(..., i18n.language, { minimumFractionDigits: 0, maximumFractionDigits: 2 }) call, so the kiloPass.tierDescription key stays in use.
• Review first: confirm no remaining references with rg "subscription-page-copy|formatKiloPassTierDescription" apps/mobile (no matches).
• iOS tier-card verification is skipped and pending owner verification; the harness host had no iOS simulator.

E2E proof

[e1] Kilo Pass subscription screen renders every tier-description in the active language (android) — Android (emulator-5554): the digest carries 'SCENE e1 OK' with all three cards — '$199 paid credits added monthly for Kilo App usage.', '$49 paid credits added monthly for Kilo App usage.', '$19 paid credits added monthly for Kilo App usage.' — and screenshot e1.png; e1-nextjs.log shows 'POST /api/trpc/kiloPass.getMobileStoreProducts?batch=1 200'. Tier cards required a temporary, reverted store-products fixture (emulator has no Play Store service); the plan's dev:capture log cannot name this client-rendered string — plan defect, no logging added.

[e3] Tier-description re-renders in the newly active language (android) — Android (emulator-5554): after switching the app language to Deutsch, e3-scene.log carries 'SCENE e3 OK' and 'Du erhältst monatlich 19 $ als bezahltes Guthaben für die Nutzung der Kilo App.' (plus the 199 $ and 49 $ cards) with locale-formatted prices, proving the screen still reads useTranslation/formatUsd; screenshot e3.png.

Owner request

Surface: the mobile app (apps/mobile).

Delete the dead Kilo Pass copy helper and stop mocking a module that no screen imports.

Problem
apps/mobile/src/lib/kilo-pass/subscription-page-copy.ts exports a single function, formatKiloPassTierDescription (line 4). No production module imports it: a repo-wide search for subscription-page-copy and formatKiloPassTierDescription matches only its own test and an inert Vitest mock. The Kilo Pass subscription screen inlines the same formatting instead (apps/mobile/src/components/kilo-pass/kilo-pass-subscription-screen.tsx:439-444 builds kiloPass.tierDescription with the same formatUsd(..., i18n.language, { minimumFractionDigits: 0, maximumFractionDigits: 2 })), so the helper is a superseded second copy of the logic.

Evidence

• apps/mobile/src/lib/kilo-pass/subscription-page-copy.ts:4 — the only export.
• apps/mobile/src/lib/kilo-pass/subscription-page-copy.test.ts:3,7 — the only importer; the test exercises the dead function only.
• apps/mobile/src/components/kilo-pass/kilo-pass-subscription-screen.test.ts:130-132 — vi.mock('@/lib/kilo-pass/subscription-page-copy', () => ({ formatKiloPassTierDescription: () => 'description' })); the screen imports no such module (its imports are at screen.tsx:1-31), so the mock is inert today and would fail to resolve if the file were deleted without also removing the mock.
• apps/mobile/src/components/kilo-pass/kilo-pass-subscription-screen.tsx:439-444 — the live inline copy that supersedes the helper.
• kiloPass.tierDescription stays in use (en.json:2837 via the inline call), so the i18n key is not orphaned.

Requested behavior

1. Delete apps/mobile/src/lib/kilo-pass/subscription-page-copy.ts.
2. Delete apps/mobile/src/lib/kilo-pass/subscription-page-copy.test.ts (it tests the deleted dead function).
3. Remove the now-inert vi.mock('@/lib/kilo-pass/subscription-page-copy', ...) block from apps/mobile/src/components/kilo-pass/kilo-pass-subscription-screen.test.ts (lines 130-132).

This is a no-behavior-change deletion: the screen keeps its inline tier-description formatting and every other copy path is untouched.

Exclusions

• Do not touch Kilo Claw or Kilo Chat.
• No backend, shared-package, schema, dependency, or i18n-catalog changes.
• Do not re-wire the screen to the helper; the goal is to delete the dead second copy, not to change language reactivity from useTranslation() to module-level i18n.t.
• Do not remove the kiloPass.tierDescription key.

Acceptance checks (run from apps/mobile)

• rg -n "subscription-page-copy|formatKiloPassTierDescription" apps/mobile returns no matches.
• pnpm format:check && pnpm typecheck && pnpm lint && pnpm check:unused all pass, and check:unused reports no unused file or module for the deleted path.
• pnpm test passes, including src/components/kilo-pass/kilo-pass-subscription-screen.test.ts with the removed mock.
• git diff --check is clean.

E2E proof (normal workflow; start the backend and Metro yourself)

• Mount the app on an Android emulator and open the Kilo Pass subscription screen; confirm each tier card still renders " paid credits added monthly for Kilo App usage." for the active language. Capture a decisive sanitized log excerpt naming the rendered tier-description string, plus a screenshot of the tier card.
• Repeat on an iOS simulator where the harness supports it. The change is platform-agnostic JS, so if iOS is unavailable, state that in the PR and keep both platforms in scope.
• Flag any check you cannot run as skipped and pending owner verification; do not report it as passed.

Prerequisites

• Install dependencies and run the mobile checks from apps/mobile per apps/mobile/AGENTS.md; the repository dev runner owns Metro and pnpm start must not be run.

Follow-ups (not changed here)

• not proved live: On an Android emulator, open the Kilo Pass subscription screen and confirm every tier card renders ' paid credits added monthly for Kilo App usage.' for the active language; capture a sanitized log excerpt naming the rendered tier-description string and a screenshot of a tier card. (no capture cited it)
• not proved live: On either device, change the active language and confirm the tier-description still re-renders in the newly active language (proves the screen still reads useTranslation/formatUsd and was not re-wired to the deleted module-level helper). (no capture cited it)
• not proved live: iOS: not run — the diff forks on no platform, so Android proves both

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Verified the dead-helper removal is self-consistent: no remaining references to subscription-page-copy or formatKiloPassTierDescription exist anywhere in the repo, the deleted test was the only importer, and the removed vi.mock block was inert because the screen test imports no such module. The live inline t('kiloPass.tierDescription', { price: formatUsd(...) }) path in kilo-pass-subscription-screen.tsx:439 keeps the i18n key in use.

This description names a scenario the proof did not capture:

• not proved live: On an Android emulator, open the Kilo Pass subscription screen and confirm every tier card renders ' paid credits added monthly for Kilo App usage.' for the active language; capture a sanitized log excerpt naming the rendered tier-description string and a screenshot of a tier card. (no capture cited it)

A repeated proof run rebuilds the same evidence, so no proof run is dispatched for a named gap. Merging with this gap open is your decision.
