fix(cache): incorporate auth state into cache key to prevent stale responses (#228) - #347
In src/services/github.js, fetchWithCache() previously cached API responses using only the normalized URL as the cache key, ignoring the authentication state (pat).
Since fetchContributors, fetchIssues, and fetchPulls paginate deeper when authenticated (maxPages = pat ? 10 : 1), page=1 shares the exact same URL whether a PAT is used or not. When a user initially explored an organization without a PAT, page 1 was cached anonymously. Later adding a PAT silently served the stale unauthenticated page 1 from the cache instead of issuing an authenticated request to GitHub (#228).
Furthermore, switching between different access tokens could potentially leak cached data fetched under a different PAT.
Updated normalizeCacheKey(url, pat) to namespace cache keys by authentication state and token identity (anon:<url> vs auth_<tokenHash>:<url>).
Uses a lightweight non-reversible hash (hashToken) for tokens to ensure each PAT receives its own isolated cache namespace without storing sensitive credentials in plain text.
Verified that switching between different PATs isolates responses and never returns stale data from a previous token.
Verified that repeating requests within the same auth state hits the cache (zero extra network calls).

Summary by CodeRabbit
Bug Fixes
GitHub request caching now keeps authenticated and unauthenticated results separate. Results from different personal access tokens are also isolated, while repeated requests with the same authentication context can reuse cached results.

Walkthrough
GitHub cache keys now distinguish anonymous requests, authenticated requests, and requests using different PATs. Cache reads and writes use the PAT scope. Tests verify separate entries and cache reuse.

Summary
Scope cache reads and writes by authentication state src/services/github.js, src/services/github.cacheKey.test.js
normalizeCacheKey adds an anonymous or authentication scope, with a token-specific hash when a PAT is provided. cacheGet, cacheSet, and fetchWithCache pass the PAT through cache reads and writes. Tests check key normalization, separate entries for anonymous requests and different PATs, authorization headers, and cache reuse.
The change separates cached GitHub responses by anonymous state and by PAT, so adding or switching a PAT fetches fresh data. No concrete merge-blocking risk was identified.

Explanation
The title states the main change: cache keys now include authentication state, which prevents stale responses after a PAT is added. The raw summary and objectives both confirm that normalizeCacheKey, cacheGet, and cacheSet now take the token and separate entries by auth scope and PAT hash. The title is specific and matches the changeset. The '(#228)' suffix refers to the linked issue and does not reduce the match.
Full details: Linked Issues check
Explanation
Issue #228 requires that fetchWithCache() keep authenticated and anonymous cache entries separate, so that adding a PAT triggers fresh requests for page 1. At the reviewed head, normalizeCacheKey(url, pat) prefixes keys with anon: or auth: / auth_<hash>:. cacheGet(key, pat), cacheSet(key, value, pat), and fetchWithCache pass pat through. The affected callers (fetchOrg, fetchRepos, fetchContributors, fetchIssues, fetchPulls) use fetchWithCache, so they inherit this scoping. The new unit tests in src/services/github.cacheKey.test.js cover anonymous-to-authenticated freshness and per-PAT isolation. The author reports the test results, but this assessment does not verify them.
Full details: Out of Scope Changes check
Explanation
The previous assessment reported added HTTP 204/409 empty-response caching as out of scope. The diff of src/services/github.js from the merge base to the reviewed head shows that this block already exists at the base. This PR only changes its call from cacheSet(url, empty) to cacheSet(url, empty, pat). The 204/409 behavior is therefore not introduced by this PR, and the previous FAIL is not supported. The remaining changes (hashToken, the normalizeCacheKey scoping, the pat parameter on cacheGet and cacheSet, and the related tests) implement the cache-key requirement of #228.

- Around line 20-21: Update the cache-key construction in the code using
`isAuth` and `scope` so authenticated requests include a stable, non-reversible
identifier derived from the PAT, while anonymous requests retain their existing
cache-key behavior. Add a test that switches between two PATs and verifies each
receives its own response.
