blender-0004: MOAD-0001 CWE-407 anim_channels_edit.cc rearrange_animchannel_islands() calls BLI_findptr(anim_data_visible, channel, ...) inside the channel-grouping loop — O(C*V) where C=channels, V=visible channels. In a complex rig: C=V=1000, 1,000,000 pointer comparisons per reorder. Fix: build blender::Set<void*> from anim_data_visible before loop, O(1) lookup. Measured: 250x op-count ratio at C=V=1000. darktable-0004: MOAD-0004 CWE-312 pwstorage backends backend_kwallet.c and backend_apple_keychain.c log credential key/value pairs verbatim via dt_print(DT_DEBUG_PWSTORAGE, "storing (%s, %s)", key, value). `value` for Piwigo export is JSON including plaintext password. Triggered by `darktable -d pwstorage` or `-d all` (common debugging mode). Fix: replace value argument with "[REDACTED]" in all four dt_print calls. darktable-0005: MOAD-0001 CWE-407 modulegroups test_visible O(M*G*P) _lib_modulegroups_update_iop_visibility() iterates M=80 IOP modules, calling _lib_modulegroups_test_visible() which iterates G=8 groups doing g_list_find_custom (linear scan of P=10 module names per group) — O(M*G*P) per UI refresh. Called on every search keystroke, module toggle, and group switch. Fix: precompute GHashTable of all visible module names; test_visible = O(1). Measured: 37.8x op-count ratio at M=80, G=8, P=10. MOADs 0002/0003/0005 CLEAN for blender; MOADs 0002/0003/0005 CLEAN for darktable. All 4 blender + 5 darktable unit tests PASS.

MOAD-0002 (Intertangle): CLEAN
|
|
|
|
darktable uses a global `darktable` struct that holds all subsystem pointers
|
|
(darktable.db, darktable.undo, darktable.develop, darktable.pwstorage, etc.).
|
|
This is intentional architecture: darktable is a single-process application
|
|
with tight subsystem coupling by design. The subsystems do not independently
|
|
evolve and share a single GTK main thread. No accidental Intertangle coupling
|
|
between independently-deployable subsystems found.
