## 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() |
**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.
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 |
| #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 |
| #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.
**Dependencies:** #156 depends on #154. Both depend on #55 conceptually. These also depend on #53 (alternative input methods) and mature API stability.

## Group 12: Demo Games & Tutorials
**2 issues — showcase/marketing**
| Issue | Title | Difficulty |
|-------|-------|------------|
| #248 | Crypt of Sokoban Remaster (7DRL prep) | Major — full game remaster |
| #167 | r/roguelikedev Tutorial Series Demo Game | Major — tutorial content + demo game |
**Dependencies:** Both benefit from a stable, well-documented API. #167 specifically needs the API to be settled.
---
## Group 13: Platform & Architecture (Far Future)
**5 issues — large features, mostly deferred**
| Issue | Title | Difficulty |
|-------|-------|------------|
| #70 | Package mcrfpy without embedded interpreter (wheels) | Major — significant build system rework |
| #62 | Multiple Windows | Major — architectural change |
| #67 | Grid Stitching / infinite world prototype | Major — new rendering/data infrastructure |
| #54 | Jupyter Notebook Interface | Major — alternative rendering target |
| #53 | Alternative Input Methods | Major — depends on #220 |
---
## Group 14: Concurrency
**1 issue — deferred**
| Issue | Title | Difficulty |
|-------|-------|------------|
| #220 | Secondary Concurrency Model: Subinterpreter Support | Major — Python 3.12+ subinterpreters |
**Dependencies:** Depends on free-threaded CPython work (#281).
