📝 Walkthrough

Walkthrough

In src/lib/api.ts, the safeFetch catch block's condition for showing the "Unable to connect to the server" toast is updated from a TypeError-only check to also match errors whose string representation includes "fetch", while still gating on !options?.silent.

Changes

safeFetch Silent Flag for Fetch Errors

Layer / File(s)	Summary
safeFetch catch: silent + fetch error detection src/lib/api.ts	The single-line condition now combines !options?.silent with (error instanceof TypeError || error.toString().includes("fetch")), so background calls passing { silent: true } suppress the connection error toast for both TypeError and other fetch-related errors.

Poem

🐇 A silent hop through offline night,
No toast to startle, all is right.
The fetch may fail, the network gone,
But freshness scores still carry on.
silent: true — the bunny's delight! 🌿

Thank you for the fix in src/lib/api.ts—that logic is exactly what we needed to silence the toast!

However, I cannot merge this PR because your branch is severely out of sync and contains unrelated, destructive changes. Your commit is attempting to:

Delete a critical ci.yml rate-limiting fix we just merged to main.
Delete all the UI badges from the README.md.
Please run git fetch upstream && git rebase upstream/main (or sync your fork) and remove all changes to ci.yml, README.md, and scripts/start-backend.bat. This PR should ONLY contain the 3 lines of code changed in src/lib/api.ts. Let me know when the diff is clean!

[BHOGALA-SRIKA]

Okay, I apologize for the messy commits and the accidental changes to ci.yml and README.md. I will check into it.

[BHOGALA-SRIKA]

I have rebased my branch onto the latest upstream/main and cleaned up the PR. All accidental changes to ci.yml, README.md, and the backend scripts have been removed. The PR now contains only the intended fix for suppressing silent error toasts in src/lib/api.ts. You can look into the FilesChanged Tab. Thank you
