Description

line auth status reports expiresAt in January 1970 and expired: true right after a successful QR login, even though the session works.

Cause

tokenExpiry() in packages/cli/src/profile-store.ts treats storage.expire as milliseconds since the epoch. The login code in packages/linejs/base/login/mod.ts stores tokenInfo[3] + tokenInfo[6], which is in epoch seconds, so the value is read ~1000x too small.

Fix

Minimal CLI-side fix: values below 1e12 are treated as epoch seconds and converted to milliseconds before building the date and computing expired. Millisecond values are still accepted, so nothing breaks if the storage format ever changes. The library's storage format is untouched, and the misleading comment is corrected.

Tests

• Added unit tests in packages/cli/test/profile-store.test.ts covering seconds/milliseconds as numbers and strings (past/now/future with a mocked clock), and missing/invalid values.
• cd packages/cli && pnpm exec vp test: 53 passed.
• pnpm --filter @evex-dev/linejs-cli run typecheck and pnpm exec vp check: no errors.
• Checked against a real logged-in profile: before the fix {"expiresAt":"1970-01-21T…","expired":true}; after the fix the expiry is a date a few days in the future with expired: false.

Checklist

• Run tests (optional)
• Add jsdoc (optional)
• Test in your environment (optional)
