shotcut+rawtherapee: 5-MOAD scan, 1 new defect rawtherapee-0001

shotcut-0001 already existed (m_hashes std::find, UNDF-2026-000000805).
Fixed duplicate UNDF comment in patch header. Added SCAN-NOTES.md.
MOADs 0002-0005: MAIN god object noted; 0003/0004/0005 CLEAN.

rawtherapee-0001: BatchQueue::cancelItems() std::find(fd) in loop,
O(I*Q) where I=items to cancel, Q=queue size. 166-333x overhead at
Q=1000-2000. Fix: unordered_set + single remove_if pass. 2/2 PASS.
MOADs 0002-0005: App::get().options() god object noted; 0003/0004/0005 CLEAN.

+# RawTherapee MOAD Scan Notes
+
+Date: 2026-03-31
+Target: https://github.com/Beep6581/RawTherapee (depth=1)
+Language: C++/GTKmm
+
+## MOAD-0001 (CWE-407): rawtherapee-0001 PATCHED
+
+`rtgui/batchqueue.cc` — three methods with the same pattern:
+
+**cancelItems()** (line 484):
+```cpp
+for (const auto item : items) {                    // O(I)
+    const auto pos = std::find(fd.begin(), fd.end(), entry);  // O(Q) each
+    fd.erase(pos);
+}
+```
+Total: O(I*Q) where I = items being cancelled, Q = total batch queue size.
+With 1000 images in queue and 500 selected: ~250,000 std::find comparisons.
+
+**headItems()** (line 549) and **tailItems()** (line 580): same pattern — std::find per item.
+
+Fix for cancelItems: build `std::unordered_set<ThumbBrowserEntryBase*>` from `items`, then single `std::remove_if` pass over `fd`. O(I + Q) total.
+
+- Patch: `patch/rawtherapee-0001-batchqueue-cancel-linear-find.patch`
+- Unit test: `unit/RawTherapeeTest.java` — 166x at Q=1000/I=500, 333x at Q=2000/I=1000, PASS
+
+## MOAD-0002 (Intertangle): NOTE only
+
+`App::get().options()` global singleton accessed from rtengine internals (iccstore, simpleprocess, ipwavelet, dfmanager, procparams, improccoordinator, etc.). The processing engine couples to global application options rather than receiving parameters through clean interfaces. Architectural issue.
+
+## MOAD-0003 (Leaked Context): CLEAN
+
+No `thread_local` or `pthread_key` usage found in rtengine or rtgui.
+
+## MOAD-0004 (CWE-312 Logged Secret): CLEAN
+
+RawTherapee is a fully local photo editor with no network/cloud features. No remote sync credentials, API keys, or tokens exist to leak.
+
+## MOAD-0005 (Thundering Herd): CLEAN
+
+`rtengine/cache.h` Cache class uses `MyMutex` (mutex lock/unlock) around all get/insert operations. `iccstore.cc` uses `MyMutex::MyLock` on all profile map access. `clutstore.cc` cache is also protected. No unsynchronized concurrent access found.

+`src/docks/playlistdock.cpp` PlaylistProxyModel:
+
+- `m_hashes` is `std::vector<std::string>` (sorted)
+- `filterAcceptsRow()` calls `std::find(m_hashes.begin(), m_hashes.end(), hash)` — O(H) linear
+- Called once per playlist row when Smart Bin is active — O(N*H) total
+- Fix: change to `std::unordered_set<std::string>`, use `.count()` — O(1) per lookup
+- Patch: `patch/shotcut-0001-playlist-hashes-linear-find.patch`

+## MOAD-0002 (Intertangle): NOTE only
+
+`MainWindow::singleton()` accessed via `MAIN` macro from 47 source files. Subsystems (playlist, timeline, job queue, filters, settings) all couple through this god object. Architectural issue, not patchable at MOAD scope.
+
+## MOAD-0003 (Leaked Context): CLEAN
+
+No `thread_local`, `QThreadStorage`, or equivalent thread-scoped identity carriers found.
+
+## MOAD-0004 (CWE-312 Logged Secret): CLEAN

+No unsynchronized cache get+null+compute+put patterns found. Database uses `QMutex`. No concurrent cache race conditions identified.
