What changes

• ConexCoreDataSource.postImportItem uses a dedicated 15 min read timeout (IMPORT_READ_TIMEOUT_MS), passed through postJson. Other calls keep the 20 s default.

Why

• A Kolibri channel import on the box takes 35-141 s. At 20 s the app reported those items as failed while the box finished them ("Imported 18 of 21 items").

Verifications

• Reproduced on the OnePlus 7T through the app: the 3 Kolibri channels false-failed at 20 s; Calibre and Kiwix items imported.
• Backend battery OnePlus -> Samsung: 22/22 items imported; the largest Kolibri import took 141 s.
• APK builds and is installed on the OnePlus. A UI re-run with the fix is still pending.
  • Deferred: make import a prepare/poll long operation like export (K2GO-507). A fixed timeout has a ceiling for very large channels.

Notes

• Delete already uses a dedicated 120 s timeout for the same reason.

Update (d61893b): adds the box half of the fix. The app reaches conex-core through nginx /k2go-api/ and the dash-node relay. That location had no read timeout, so nginx returned 504 after 60 s on a Kolibri import. It now waits up to 3600 s. dash-node 1.4.8 (+CHANGELOG), so deployed boxes get it on self-update.

Device (OnePlus 7T, nginx live-patched with the same lines): import from disk 21 of 21, two runs.

Update (613386b..8054cdc): import is now a long operation, so no fixed timeout sits on its path.

• conex-core 0.3.4: POST /v1/import/item starts the import and returns an opId. GET /v1/import/status/{op} polls it. DELETE /v1/import/{op} cancels it. Import and export share one op registry and one abandonment sweep.
• • A liveness watchdog supervises the Kolibri import and export CLIs. Moving bytes = alive, with no limit. CPU only = a longer window. No progress = stalled: the op is cancelled and reported. The window is relative to the task. A signal-9 exit is reported as a likely out-of-memory kill. The rule is in ADR-long-running-operation-contract.
• • App: ContentImportService starts the op and polls it, like the export. The 15-min read timeout from 4befb14 is removed.
• • 213 conex-core tests pass. Two review passes done.
    Device (OnePlus 7T, real relay path nginx -> dash-node -> conex-core): the POST returns in 0.02-0.04 s. A 3.3 GB Kolibri channel completes in 55 s. It also completes with nginx at its default 60 s.

Update (d70e2f5): a fully successful import now confirms and returns to the Library.

UI changes:

• The settled message "Imported N items." shows in green (k2go_leaf) on full success. It stays ink on a partial result or an error.
• • Below it: "Opening your library in 3 s..." counts down, then the app opens the Library tab. A "Cancel" link stops the countdown and keeps the screen (Finish stays).
• • No new strings: reuses k2go_clone_exit_redirecting and k2go_setup_cancel (already in all locales).
• • Same screen for import from a drive and for receive over Wi-Fi.
