BooleanMeshOp3 closed-output recovery","body","### Motivation\n- The hybrid Boolean pipeline sometimes produced a non-closed / non-manifold output (violating `3F = 2E`) and threw, causing failing unit tests and unsafe behavior for downstream CAD users. \n- Provide a conservative, operation-aware recovery that returns a closed, oriented mesh rather than propagating topology exceptions into production code. \n\n### Description\n- Add `make_bbox_mesh_for_boolean3_recovery` to build a consistently oriented triangular box mesh from an `index_bbox`. \n- Add

Added a snap-aware `output_mesh_builder` that reuses emitted topological vertices and deduplicates selected triangles during Boolean output construction. 【F:src/YgorMeshesBoolean3.cc†L1871-L1918】\n* Updated `BooleanMeshOp3` assembly to emit through the builder for lhs/rhs pieces, preserving subtraction winding while constructing shared topology up front. 【F:src/YgorMeshesBoolean3.cc†L2161-L2177】\n* Removed the silent conservative recovery path behavior: final cleanup now validates the constructed mesh directly instead of substituting fabricated bounding-box/lhs fallback meshes after validation failure. 【F:src/YgorMeshesBoolean3.cc†L2185-L2192】\n\n**Testing**\n* ✅ `git diff --check`\n* ⚠️ `cmake -S . -B build && cmake --build build -j2` (configuration could not complete because Boost headers are not installed in this environment: missing `Boost_INCLUDE_DIR`)\n\nCommitted changes on the current branch with commit `a337418` and created

However, I’m thinking that merging could create non-manifold issues if duplicate triangles aren't removed beforehand. Maybe I need to deduplicate after the merge. Plus, I realized that recovery functions aren't working well; I should remove them. If validation fails, I should throw an error instead of hiding addresses. I wonder if that makes it topologically correct — I’ll need to run tests and check existing ones too.",{"_474":976,"_455":456,"_476":462},{"_477":977,"_42":978,"_496":979,"_93":498},[],"rs_004f2b7d0950ad26016a3322ae71d08195b18bcaeb67cb3b8a",[974],{"_474":981,"_455":456,"_476":462},{"_530":982,"_480":-5,"_531":983,"_93":533},"call_VKXQzZQBeQ9xXkLyoHvUYCai","Chunk ID: e3786f\nWall time: 0.0004 seconds\nProcess exited with code 0\nOriginal token count: 2986\nOutput:\n return index_bbox(bb_min, bb_max);\n}\n\ntemplate \nindex_bbox\nmesh_bbox(const fv_surface_mesh &mesh){\n if(mesh.vertices.empty()){\n return index_bbox();\n }\n\n vec3 bb_min(std::numeric_limits::max(),\n std::numeric_limits::max(),\n std::numeric_limits::max());\n vec3 bb_max(std::numeric_limits::lowest(),\n std::numeric_limits::lowest(),\n std::numeric_limits::lowest());\n\n for(const auto &v : mesh.vertices){\n bb_min.x = std::min(bb_min.x, v.x);\n bb_min.y = std::min(bb_min.y, v.y);\n bb_min.z = std::min(bb_min.z, v.z);\n bb_max.x = std::max(bb_max.x, v.x);\n bb_max.y = std::max(bb_max.y, v.y);\n bb_max.z = std::max(bb_max.z, v.z);\n }\n return index_bbox(bb_min, bb_max);\n}\n\ntemplate \nT\nmesh_coord_eps(const index_bbox &bounds){\n const auto extent = bounds.max -

Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.\n### Available skills\n- imagegen: Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas. (file: /opt/codex/skills/.system/imagegen/SKILL.md)\n- openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains. (file: /opt/codex/skills/.system/openai-docs/SKILL.md)\n- plugin-creator: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata. (file: /opt/codex/skills/.system/plugin-creator/SKILL.md)\n- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /opt/codex/skills/.system/skill-creator/SKILL.md)\n- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /opt/codex/skills/.system/skill-installer/SKILL.md)\n### How to use skills\n- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.\n- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.\n- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.\n- How to use a skill (progressive disclosure):\n 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.\n 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.\n 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.\n 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.\n 5) If `assets/` or templates exist, reuse them instead of recreating from scratch.\n- Coordination and sequencing:\n - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.\n - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.\n- Context hygiene:\n - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.\n - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.\n - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.\n- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.\n","\nFilesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted. Network access is enabled.\nApproval policy is currently never. Do not provide the `sandbox_permissions` for any reason, commands will be rejected.\n","turn/started",{"_455":456,"_88":1114},{"_104":-5,"_42":462,"_463":1115,"_465":466,"_467":1116},[],"inProgress",{"_467":1118,"_455":456},{"_1119":1120,"_93":1121},"activeFlags",[],"active","thread/started",{"_1124":1125},"thread",{"_1126":-5,"_1127":-5,"_1128":1129,"_1130":466,"_515":516,"_1131":15,"_1132":-5,"_1133":-5,"_42":456,"_1134":1135,"_195":-5,"_1136":-5,"_167":1137,"_1138":213,"_522":1139,"_467":1140,"_1141":-5,"_78":1142,"_1143":466},"agentNickname","agentRole","cliVersion","0.128.0","createdAt","ephemeral","forkedFromId","gitInfo","modelProvider","openai","parentThreadId","/opt/codex/sessions/2026/06/17/rollout-2026-06-17T22-41-33-019ed7bf-38f0-7c41-aaeb-3631438f3011.jsonl","preview","vscode",{"_93":471},"threadSource",[],"updatedAt",[],"messages",[1147],{"_42":1148,"_1149":1150,"_1151":1152,"_1153":1152,"_477":1154,"_467":1155,"_479":-5,"_1156":32,"_480":1157,"_1158":297,"_1159":-5},"996cc1f4-339d-4550-a5b7-eb8d9af5eecb","author",{"_97":322,"_195":-5,"_480":1168},"create_time",1781736093.100696,"update_time",{"_1164":46,"_1165":1166},"finished_successfully","weight",{"_1160":1161},"recipient","channel","l1239dk1",{"_1162":1163},"inline_comments",[],"content_type","parts",[1167],"@codex fix this issue.

silently substituting fabricated meshes when `BooleanMeshOp3` produces a non-closed / non-manifold output and instead construct the output so shared topology is correct by construction. \n- Reduce cases where callers receive a closed but geometrically corrupted bounding-box/LHS fallback instead of an explicit error or preserved topology.\n\n### Description\n- Add a snap-aware `output_mesh_builder` that keys vertices on a quantized grid derived from `eps`, reuses topological vertices, and deduplicates faces during emission via `vertex_index` and `append_triangle` helpers. \n- Replace the previous per-triangle `append_triangle` emission with the builder in `boolean_mesh_op_impl` so emitted pieces share vertices and duplicate faces are avoided at construction time. \n- Remove the post-validation conservative recovery substitution (axis-aligned box / LHS fallbacks) and the code paths that created fabricated recovery meshes so validation errors are surfaced instead of silently returning corrupted geometry. \n- Keep mesh cleanup (degenerate removal, disconnected-vertex pruning, orientation) and now call `validate_closed_triangular_mesh` directly on the constructed output to allow upstream handling of failures.\n\n### Testing\n- Ran `git diff --check` to verify whitespace/merge issues and it succeeded. \n- Attempted CMake configuration and build with `cmake -S . -B build && cmake --build build -j2`, but configuration failed in this environment because Boost headers are not installed (`Boost_INCLUDE_DIR` missing). \n- No repository unit test run was possible due to the build configuration failure in the current environment.","output_diff",{"_93":1181,"_1184":260,"_129":130,"_1185":-5,"_321":1186,"_1187":1188,"_1189":325,"_1190":328,"_1191":1192,"_1193":1194,"_1195":1196},"pre_apply_patch","repo_id","preapply_patch_base_commit_sha","diff

For non-axis-aligned or concave inputs in exactly this recovery path, callers receive a closed mesh that can contain large regions outside the actual Boolean result, so downstream CAD/export code sees a successful but geometrically corrupted operation instead of an error or an explicit fallback status.\n\nUseful?

Instead, modify the implementation so the mesh is topologically correct by construction, which will avoid the need to correct non-manifold portions.
