Superseded by #23918 (refreshes against current next).

This PR's investigation is correct (stale pinned Chonk inputs → debug-only kernel_return_data_match assert in the nightly debug build), but it stalled: claudebox opened it as a draft, so the ci-refresh-chonk refresh CI never ran (no ci workflow executed on the head sha — only Netlify previews), and its base (81ecf81, 2026-06-02) has since gone stale while more breaking protocol-layout changes landed on next. Re-opened fresh as #23918 against current next. Closing to avoid two competing refresh PRs.


Original description below.

Problem

The Nightly Debug Build failed on next. The single failing test is bbapi_tests ChonkPinnedIvcInputsTest.AllPinnedFlows (flow deploy_ecdsar1+sponsored_fpc), which crashes with a debug-only assertion (kernel_return_data_match, chonk.cpp:167). Just before the crash the final hiding_kernel reports Pub inputs offset mismatch: 669 vs 673 and a VK commitment mismatch.

Root cause

Stale pinned Chonk inputs (last re-pinned 2026-05-21, 209dde8e69a27c9f), now out of sync with breaking protocol-layout changes on next (#23197, #23218, #23217, #23106, #23510, #23764). Debug-only assert + verbose VK check, which is why release CI is green and only the nightly debug build catches it.
