+# McRogueFace Issue Triage — April 2026
+
+**46 open issues** across #53–#304. Grouped by system, ordered by impact.
+
+---
+
+## Group 1: Render Cache Dirty Flags (Bugfix Cluster)
+
+**4 issues — all quick-to-moderate fixes, high user-visible impact**
+
+These are systemic bugs where Python property setters bypass the render cache invalidation system (#144). They cause stale frames when using `clip_children` or `cache_subtree`. Issue #291 is the umbrella audit; the other three are specific bugs it identified.
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #291 | Audit all Python property setters for missing markDirty() calls | Medium — systematic sweep of all tp_getset setters |
+| #290 | UIDrawable base x/y/pos setters don't propagate dirty flags to parent | Quick — add markCompositeDirty() call in set_float_member() |
+| #289 | Caption Python property setters don't call markDirty() | Quick — add markDirty() to text/font_size/fill_color setters |
+| #288 | UICollection mutations don't invalidate parent Frame's render cache | Quick — add markCompositeDirty() in append/remove/etc |
+
+**Dependencies:** None external. #291 depends on #288–#290 being fixed first (or done together).
+
+**Recommendation: Tackle first.** These are correctness bugs affecting every user of the caching system. The fixes are mechanical (add missing dirty-flag calls), low risk, and testable. One focused session can close all four.
+
+---
+
+## Group 2: Grid Dangling Pointer Bugs
+
+**3 issues — moderate fixes, memory safety impact**
+
+All three are the same class of bug: raw `UIGrid*` pointers in child objects that dangle when the parent grid is destroyed. Part of the broader memory safety audit (#279).
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #270 | GridLayer::parent_grid dangling raw pointer | Moderate — convert to weak_ptr or add invalidation |
+| #271 | UIGridPoint::parent_grid dangling raw pointer | Moderate — same pattern as #270 |
+| #277 | GridChunk::parent_grid dangling raw pointer | Moderate — same pattern as #270 |
+
+**Dependencies:** These are the last 3 unfixed bugs from the memory safety audit (#279). Fixing all three would effectively close #279.
+
+**Recommendation: Tackle second.** Same fix pattern applied three times. Closes the memory safety audit chapter.
+
+---
+
+## Group 3: Animation System Fixes
+
+**2 issues — one bugfix, one feature**
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #256 | Animation system bypasses spatial hash updates for entity position | Moderate — hook animation property changes into spatial hash |
+| #218 | Color and Vector animation targets | Minor feature — compound property animation support |
+
+**Dependencies:** #256 is independent. #218 is a nice-to-have that improves DX.
+
+---
+
+## Group 4: Grid Layer & Rendering Fixes
+
+**2 issues — quick fixes**
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #257 | Grid layers with z_index of zero are on top of entities | Quick — change `>=0` to `>0` or similar in draw order |
+| #152 | Sparse Grid Layers | Major feature — default values + sub-grid chunk optimization |
+
+**Dependencies:** #257 is standalone. #152 builds on the existing layer system.
+
+---
+
+## Group 5: API Cleanup & Consistency
+
+**1 issue — quick, blocks v1.0**
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #304 | Remove camelCase module functions before 1.0 | Quick — delete 4 method entries from mcrfpyMethods[], update tests |
+
+**Dependencies:** Snake_case aliases already added. This is a breaking change gated on the 1.0 release.
+
+---
+
+## Group 6: Multi-Tile Entity Rendering
+
+**5 issues — parent + 4 children, all tier3-future**
+
+Umbrella issue #233 with four sub-issues for different approaches to entities larger than one grid cell.
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #233 | Enhance Entity rendering and positioning capabilities (parent) | Meta/tracking |
+| #234 | Entity origin offset for oversized sprites | Minor — add pixel offset to entity draw position |
+| #235 | Texture display bounds for non-uniform sprite content | Minor — support non-cell-aligned sprite regions |
+| #236 | Multi-tile entities using oversized sprites | Minor — render single large sprite across cells |
+| #237 | Multi-tile entities using composite sprites | Major — multiple sprite indices per entity |
+
+**Dependencies:** #234 is the simplest starting point. #236 and #237 build on #234/#235.
+
+---
+
+## Group 7: Memory Safety Audit Tail
+
+**9 issues — testing/tooling infrastructure for the #279 audit**
+
+These are the remaining items from the 7DRL 2026 post-mortem. The actual bugs are mostly fixed; these are about preventing regressions and improving the safety toolchain.
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #279 | Engine memory safety audit — meta/tracking | Meta — close when #270/#271/#277 done |
+| #287 | Regression tests for each bug from #258–#278 | Medium — write targeted test scripts |
+| #285 | CI pipeline for debug-test and asan-test | Medium — CI/CD configuration |
+| #286 | Re-enable ASan leak detection | Tiny — remove detect_leaks=0 suppression |
+| #284 | Valgrind Massif heap profiling target | Tiny — add Makefile target |
+| #283 | Atheris fuzzing harness for Python API | Major — significant new infrastructure |
+| #282 | Install modern Clang for TSan/fuzzing | Minor — toolchain upgrade |
+| #281 | Free-threaded CPython + TSan Makefile targets | Minor — Makefile additions |
+| #280 | Instrumented libtcod debug build | Minor — rebuild libtcod with sanitizers |
+
+**Dependencies:** #286 depends on #266/#275 (both closed). #287 depends on the actual bugs being fixed. #283 depends on #282.
+
+---
+

+
+**3 issues — foundation work for game data**
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #293 | DiscreteMap serialization via bytes | Minor — add bytes() and from_bytes() to DiscreteMap |
+| #294 | Entity.gridstate as DiscreteMap reference | Minor — refactor internal representation |
+| #149 | Reduce the size of UIGrid.cpp | Refactoring — break 1400+ line file into logical units |
+
+**Dependencies:** #294 depends on #293. #149 is independent refactoring.
+
+---
+
+## Group 9: Performance Optimization
+
+**4 issues — significant effort, needs benchmarks first**
+
+| Issue | Title | Difficulty |
+|-------|-------|------------|
+| #255 | Tracking down performance improvement opportunities | Investigation — profiling session |
+| #117 | Memory Pool for Entities | Major — custom allocator |
+| #145 | TexturePool with power-of-2 RenderTexture reuse | Major — deferred from #144 |
+| #124 | Grid Point Animation | Major — per-tile animation system, needs design |
+
+**Dependencies:** #255 should be done first to identify where optimization matters. #145 builds on the dirty-flag system (#144, closed). #124 is a large standalone feature.
+
+---
+

+## Summary by Priority
+
+| Priority | Groups | Issue Count | Session Estimate |
+|----------|--------|-------------|-----------------|
+| **Do now** | G1 (dirty flags), G2 (dangling ptrs) | 7 | 1 session |
+| **Do soon** | G3 (animation), G4 (grid fixes), G5 (API cleanup) | 5 | 1 session |

+| **Future** | G11 (LLM), G12 (demos), G13 (platform), G14 (concurrency) | 10 | unbounded |
+
+## Recommended First Session
+
+**Groups 1 + 2: Dirty flags + dangling pointers (7 issues)**
+
+Rationale:
+- All are correctness/safety bugs, not features — fixes don't need design decisions
+- Dirty flag fixes (#288-#291) share the same mechanical pattern: add missing `markDirty()` or `markCompositeDirty()` calls
+- Dangling pointer fixes (#270, #271, #277) share the same pattern: convert `UIGrid*` to `weak_ptr<UIGrid>` or add invalidation on grid destruction
+- Closing these also effectively closes the meta issue #279
+- High confidence of completing all 7 in one session
+- Clears the way for performance work (Group 9) which depends on correct caching
