 - **Per-student detail page (ENH-021, #66):** new `GET /mahasiswa/detail/(:any)` → `Mahasiswa::detail()` renders a single student's full biodata record (all columns from `GetBiodataMahasiswa`) read-only, with a "Detail" button added to each row in the Mahasiswa list. Reuses the `fetchBiodata($id)` single-record fetch shared with `edit()`.
 - **Pagination & UI/UX refinements on menu pages (ENH-022, #68):** the three NeoFeeder menu pages (Mahasiswa, Aktivitas Kuliah, Mahasiswa Lulus/DO) gained a page-size selector (10/20/50/100), a "Halaman X dari Y" indicator with total count (via `GetCount*` endpoints), First/Prev/Next/Last links, and accessible `<nav>` markup; list headers now use human-readable column labels. Also fixes a latent bug where typed filters were stripped before reaching the API (filter is now built as a SQL-string).
 - **Fill missing thesis grade (ENH-010, #110):** the Excel template gains an optional `nilai_skripsi` letter-grade column; at submission (`finish()`) the graduation wizard fills a thesis/skripsi course that is registered but still has no grade (via `UpdateNilaiPerkuliahanKelas`, composite key `id_registrasi_mahasiswa` + `id_kelas_kuliah` from the cloud transcript row) using the Excel value — only when the grade is currently missing and a value was provided. Card 3 shows the value and tags the row "(akan diisi)".
+- **Verifikasi IPK menu (ENH-011, #115):** a dedicated `/verifikasi-ipk` bulk check/correct menu. Upload an Excel (nim + ipk), and the app compares each student's Excel IPK against their last active semester's IPK in Neo Feeder, showing NIM/name/Neo IPK/Excel IPK/semester/cocok-beda and a checkbox only for rows with a live active last semester. Checked rows push the Excel IPK to Neo Feeder (`UpdatePerkuliahanMahasiswa`) and the per-row results (success/failure with reason) are shown on a summary page. Uses a separate cache store + resume cookie so it never clobbers the graduation WizardProgress.

 - **Actual Implemented:** Added a `nilai_skripsi` column (letter grade) to the Excel template — `EXCEL_HEADERS`, `downloadTemplate()` (header + example `A`), and `parseExcel()` (stored uppercased on each student record). Added `NeoFeeder::updateNilaiPerkuliahanKelas($token, $idRegistrasi, $idKelas, $record)` using `sendMutation('UpdateNilaiPerkuliahanKelas', ...)` with composite key `id_registrasi_mahasiswa` + `id_kelas_kuliah` (key schema verified live via GetDictionary: key `id_registrasi_mahasiswa` + `id_kelas_kuliah`, record `nilai_huruf`/`nilai_angka`/`nilai_indeks`). In `Graduation::finish()`, for each saved student with a non-empty `nilai_skripsi`, the thesis/skripsi course is re-resolved via `getCekTranskripMahasiswa`; a new private helper `findMissingGradeThesis()` finds the thesis row whose grade is currently missing (`hasGrade == false` — `nilai_huruf`/`nilai_angka` empty) and returns its `id_reg_pd`/`id_kls` from the cloud row (both verified live on real data), then `updateNilaiPerkuliahanKelas` is called with only `record.nilai_huruf` = the Excel value. The push happens only when the grade is still missing; noise results are reported in the finish guidance. In `wizard.php` card 3, a thesis row without a grade now shows the Excel value with a "(akan diisi)" tag instead of a bare "Belum ada nilai" when a value was provided.
 - **Changes:** The Excel template now carries an optional `nilai_skripsi` letter-grade column. A registered-but-ungraded thesis/skripsi course is filled in with the Excel letter grade at submission (`finish()`), only when it currently has no grade; students without a value in that column are left untouched. Card 3 indicates which thesis rows will be filled in.

+### ENH-011 — Verify and fix last-semester IPK in bulk via Excel
+- **Status:** `implemented`
+- **Issue:** #115
+- **Recorded:** 2026-08-31
+- **Implemented:** 2026-08-31
+- **Problem:** Several (possibly all) students have a last-semester `ipk` that is not up to date in Neo Feeder. The graduation wizard only surfaces the last-semester IPK for the students being processed one at a time; there is no dedicated screen to bulk-verify and correct the last-semester IPK across many students against an external source.
+- **Possible Fix:** Add a dedicated read-only "Verifikasi IPK" menu that takes an Excel file (Graduation template: `nim` + `ipk` columns), reads each student's last-semester `ipk` from Neo Feeder (`getAktivitasKuliahMahasiswa`, largest `id_semester`), shows a comparison (Neo Feeder IPK vs Excel IPK, cocok/beda) batch-by-batch, lets the admin tick the rows to fix, and pushes `updatePerkuliahanMahasiswa(['ipk' => ...])` only to the **active** last semester (`a_periode_aktif=1`, ENH-007 rule). State stored in a cache + resume cookie separate from the graduation `WizardProgress` so the two do not collide. Processing is batch-by-batch (one `getAktivitasKuliahMahasiswa` call per student) to avoid the 60 s PHP time limit.
+- **Actual Fix:** Added `VerifikasiIpk` controller (`/verifikasi-ipk`, batch-by-batch comparison) + `VerifikasiIpkStore` library (cache prefix `ipk_verif_`, resume cookie `ipk_verif_resume`), routes, sidebar menu, and views (`index`/`verification`/`results`). The push uses a full `UpdatePerkuliahanMahasiswa` record — the whole active last-semester row from `getAktivitasKuliahMahasiswa` (minus the key) plus `id_pembiayaan` resolved via `GetListRiwayatPendidikanMahasiswa` and the `ipk` overridden with the Excel value — because Neo Feeder rejects partial records (`id_status_mahasiswa`, `biaya_kuliah_smt`, `id_pembiayaan` all demanded even though the GetDictionary schema lists only `id_status_mahasiswa` as NOT NULL). Per-row results (success/failure with the Neo Feeder error message) are shown on the `results` page. `apply()` uses `set_time_limit(0)` for large batches.
+- **Actual Implemented:** 2026-08-31
+- **Changes:** New `app/Controllers/VerifikasiIpk.php`, `app/Libraries/VerifikasiIpkStore.php`, `app/Views/verifikasi_ipk/*`; `NeoFeeder.php` gained `getListRiwayatPendidikanMahasiswa()`; routes + sidebar menu added.
