WalkthroughThe change adds a shared ChangesStorage centralization
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The refactor routes cached data and credentials through a shared utility, but malformed stored values can cause UI failures and hidden storage errors can leave a cleared credential persisted. These concrete current-head correctness and credential-lifecycle risks should be fixed or explicitly accepted before merging. Suggested reviewers: Poem

In `@src/context/AppContext.jsx`:
- Around line 133-135: Update the recent-search readers in
ContributorProfilePage and HomePage to replace direct localStorage access and
the literal oe_recent key with storage.get(STORAGE_KEYS.RECENT_SEARCHES).
Preserve each reader’s existing behavior while routing key lookup and JSON
handling through the shared storage utility.
- Line 10: Update getStoredRateLimit to use the object returned by storage.get
directly, removing the redundant JSON.parse while preserving its existing
validation and fallback behavior.
In `@src/utils/storage.js`:
- Around line 10-16: Update the storage get flow for STORAGE_KEYS.PAT so a raw
legacy oe_pat value that is not JSON-encoded is returned as the PAT instead of
falling through to null after JSON.parse fails. Preserve JSON parsing for the
current storage format and ensure the migration or fallback is one-time and does
not alter behavior for other keys.

Keep non-PAT storage reads type-safe.
storage.get returns arbitrary parsed or raw values. For a malformed or wrong-shaped oe_rate_limit, src/context/AppContext.jsx returns the value because stored.reset at Line 16 is undefined. For a malformed or wrong-shaped oe_recent, src/pages/HomePage.jsx calls recent.map at Line 109 on a non-array and throws during render. Preserve the raw legacy fallback only for STORAGE_KEYS.PAT, and validate the rate-limit object and recent-search array for other keys.
Proposed fix
} catch {
- return value
+ return key === STORAGE_KEYS.PAT ? value : null
}Also validate the expected shapes at the rate-limit and recent-search read sites.
