+# kdenlive-0010 — CWE-407: KeyframeModelList::checkConsistency() QList::contains() O(P*K^2)
+
+## Target
+Kdenlive (KDE video editor) — `src/assets/keyframes/model/keyframemodellist.cpp`
+
+## MOAD
+0001 — The Sedimentary Defect (CWE-407)
+
+## Severity
+LOW-MEDIUM
+
+## Complexity
+O(P * K^2) where P = number of linked parameters, K = number of keyframe positions
+
+## Description
+
+`KeyframeModelList::checkConsistency()` is called at clip load time when a clip
+has a multi-parameter keyframe model (e.g., a position/transform effect with
+linked X, Y, scale, and rotation parameters). It performs two O(P * K^2) sweeps:
+
+**Phase 1 — building union keyframe list:**
+```cpp
+QList<GenTime> fullList;
+for (const auto &param : m_parameters) {        // O(P)
+    QList<GenTime> list = param.second->getKeyframePos();
+    for (auto &time : list) {                    // O(K)
+        if (!fullList.contains(time)) {          // O(K) — QList linear scan!
+            fullList << time;
+        }
+    }
+}
+```
+
+**Phase 2 — checking each param has all positions:**
+```cpp
+for (const auto &param : m_parameters) {        // O(P)
+    QList<GenTime> list = param.second->getKeyframePos();
+    for (auto &time : fullList) {               // O(K)
+        if (!list.contains(time)) {             // O(K) — QList linear scan!
+            // re-add missing keyframe
+        }
+    }
+}
+```
+
+`QList<GenTime>::contains()` is a linear scan — O(K) per call. Both phases are
+O(P * K^2). P is small (2-10 parameters), but K grows with clip duration and
+keyframe density. A motion-tracked clip, a clip with per-frame opacity changes,
+or a clip exported from animation software can have 1000+ keyframes.
+
+`GenTime` uses floating-point delta equality (`fabs(m_time - op.m_time) < s_delta`),
+which is incompatible with hash-based sets. However, `GenTime` has `operator<`
+(strict weak ordering), making `std::set<GenTime>` a correct O(log K) alternative.
+
+## Hot Path
+
+Called from `AssetParameterModel::setParameter()` (line 254) for every clip
+with a linked keyframe model during project load, paste, or undo/redo. On a
+timeline with 50 clips each having 500 keyframes on 3 linked parameters:
+- Defect: 50 * 750,000 = 37.5M comparisons at load
+- Fixed: 50 * 3,000 = 150,000 comparisons at load
+- Speedup: 250x
+
+## Fix
+
+Replace `QList<GenTime> fullList` deduplication with `std::set<GenTime>` using
+`fullSet.insert(time).second` (returns true if inserted), and build a per-param
+`std::set<GenTime> listSet` for the membership check in phase 2:
+
+```cpp
+#include <set>
+
+void KeyframeModelList::checkConsistency()
+{
+    if (m_parameters.size() < 2) return;
+
+    std::set<GenTime> fullSet;
+    QList<GenTime> fullList;
+    for (const auto &param : m_parameters) {
+        QList<GenTime> list = param.second->getKeyframePos();
+        for (auto &time : list) {
+            if (fullSet.insert(time).second)   // O(log K), true if newly inserted
+                fullList << time;
+        }
+    }
+    Fun local_update = []() { return true; };
+    auto type = KeyframeType::KeyframeEnum(KdenliveSettings::defaultkeyframeinterp());
+    for (const auto &param : m_parameters) {
+        QList<GenTime> list = param.second->getKeyframePos();
+        const std::set<GenTime> listSet(list.begin(), list.end());  // O(K log K) once
+        for (auto &time : fullList) {
+            if (listSet.find(time) == listSet.end()) {   // O(log K)
+                // re-add missing keyframe
+            }
+        }
+    }
+}
+```
+
+## Benchmark
+
+| P | K    | Before (ops) | After (ops) | Speedup |
