Private temporary binaries and reports are retained for diagnosis, not deleted; their path is printed before the build. kcov reports line coverage only; branch coverage is not available from this setup. It requires a runner that permits ptrace and can trace the test ELF/DWARF; incompatibility is a tooling failure, not zero-percent or successful coverage. + +The collector traces private LLVM-built ELF copies using the Nix runtime library search path. For dynamic ELFs it uses `patchelf` to select `ZIGCRAFT_DYNAMIC_LINKER`, when configured, before invoking kcov. Cached originals and production/integration builds are untouched. This matters on Ubuntu: `zig build test` invokes the Nix loader explicitly, but kcov executes the ELF using `PT_INTERP`; a host glibc loader combined with newer Nix libc can crash before any tests run. `LD_LIBRARY_PATH` alone cannot select a compatible loader. Rewriting Zig's native Debug ELF layout previously aborted; this collector explicitly builds with LLVM instead. A link-time override was also tested, but Zig 0.16's runtime-library subcompilations rejected it with `LldCannotSpecifyDynamicLinkerForSharedLibraries`. + +The collector requires `readelf` and `patchelf`, retains original and final program headers and dynamic dependencies beside each private ELF, and prints its original interpreter before collection. It verifies that an interpreter patch applied exactly; this is not an ABI-equivalence test based on store-path names. Static ELFs need no interpreter. Inspection, patching, and collector failures still fail immediately. A successful test process or kcov exit code is insufficient: the merged report must contain instrumented lines in both `src/` and `modules/`; bridge-only or partial-scope data is not full-suite coverage. In particular, unsupported DWARF/collector combinations can execute every test while reporting zero lines; this remains coverage unavailable. + +The audit A/B verification isolated the missing lines to Zig 0.16.0's default x86_64 Debug backend (`stage2_x86_64`) and kcov 43: the embedded source paths matched the include prefixes, but native-backend reports omitted `src/`. Setting `std.Build.TestOptions.use_llvm = true` produced usable line maps with the same paths and filters. The explicit `-Dtest-llvm` option applies only to direct unit-test executables; leaving it unset preserves Zig's normal backend selection, and it does not change application, benchmark, or integration builds. The collector requests it explicitly rather than weakening validation. + +The verified LLVM Debug collection ran all 31 executables (1,917 tests passed) and validated 21,485 hit lines out of 27,431 instrumented project lines. These counts include test code and only source lines emitted into the test ELFs; they are not a percentage of every maintained source line or a branch-coverage claim. The native-backend failure and LLVM success evidence were both preserved. + +The PR981 loader regression was reproduced in an Ubuntu 24.04 container with glibc 2.39 and the Nix glibc 2.42 runtime search path. A private LLVM `engine-core-tests` copy using `/lib64/ld-linux-x86-64.so.2` exited under kcov with signal 11 before test output; selecting the Nix interpreter passed all 18 tests. The patched application ELF passed all 279 tests, and their merged report validated 6,053/7,066 project lines hit across both required source scopes. A subsequent fresh full collection with the updated script passed all 31 executables and validated 21,513/27,459 project lines hit across 282 files. The container experiment used local ELFs with a controlled host-interpreter copy, not the unavailable failed CI ELF; the Ubuntu CI rerun remains the final end-to-end workflow confirmation. ## Sanitizer Nightly The `Sanitize` workflow runs nightly and on `workflow_dispatch` with: ```bash -devenv shell zig build -Dsanitize=address test +devenv shell zig build -Dsanitize=c test ``` -The project is pinned to Zig 0.16.0. That compiler exposes `-fsanitize-c` and `-fsanitize-thread`, but not an LLVM AddressSanitizer build flag through `std.Build`. The repository keeps `-Dsanitize=address` as the CI entrypoint requested by the audit, and currently maps it to Zig's full C undefined-behavior sanitizer support. Failures fail the scheduled workflow check and should be triaged from the uploaded log artifact. +The project is pinned to Zig 0.16.0. This mode sets `std.Build.Module.sanitize_c = .full`, C undefined-behavior sanitization (UBSan), **not LLVM AddressSanitizer**. The canonical build spelling is `c-undefined`; `c` is the supported short alias used in CI. The old `address` alias is deprecated and warns; it never provided ASan. This does not imply memory-error instrumentation of all Zig code or prebuilt C/C++ dependencies. Debug/ReleaseSafe checks and testing allocators provide separate safety signals. Failures fail the scheduled workflow and should be triaged from its log artifact. + +## Deterministic Corpus Versus Fuzz Campaign + +Tests named `fuzz corpus` run fixed malformed inputs, boundary coordinates, or deterministic pseudo-random samples in ordinary CI. Passing them is regression evidence only. A coverage-guided campaign needs explicitly fuzz-enabled targets, a seed/corpus, a bounded runtime budget, retained crashing inputs, and recorded compiler/runner versions. No scheduled coverage-guided campaign or ASan campaign is claimed by the current workflows. Preserve discovered inputs as regression fixtures rather than deleting diagnostics. + +## Shader Freshness + +Ordinary builds and tests compare compiled GLSL against tracked runtime SPIR-V without overwriting it. `devenv shell zig build shaders` is the explicit regeneration step; `devenv shell zig build test-shaders` checks freshness, size baselines, and shadow ABI. A stale artifact must fail before regeneration, not be silently repaired by the test under evaluation. ## Vulkan Validation -The integration and world-smoke CI steps run under Lavapipe with `VK_LAYER_KHRONOS_validation`, core validation, and best-practices validation enabled.

Missing output, stale checkout screenshots, timeout, decoder/comparison errors, or skipped comparison cannot turn the job green. Artifacts remain available for human diagnosis; the capture job receives no provider token or PAT and does not run an AI agent. + ## Current Baseline Status The tracked `golden/menu.png` is known to be black and is therefore intentionally **not a valid baseline**.

None of the corrections retunes terrain, +climate noise, biome ranges, priorities, surfaces, or the Voronoi algorithm. +The sole production change is a separate water-coverage reporting metric. +All original tests remain; the coastal transition fixture now exercises edge +injection rather than expecting an edge-only biome from natural selection. + +## Failure Causes + +1. **Low ridge mask:** `50728aec` (#679) deliberately changed ordinary mountains' + minimum ridge mask from `0.1` to `0.0`. Test rejection on `jagged_peaks`, which + still requires a ridge, immediately below and exactly at its minimum. Also + protect ridge-free ordinary mountains with an accepted zero-mask sample. +2. **Baseline wet biome:** `a408e2d3` (#671) changed constrained selection from + heat/humidity Voronoi points to the authoritative biome definitions. The old + swamp point accepted continentalness `0.45`; the current definition requires + at least `0.48`. Move the wet fixture inland to `0.6`, retaining expected + `swamp`. The same test also contained an unreachable `coastal_plains` natural + selection expectation: that definition is explicitly edge-injection-only. + Preserve its original inputs in the transition test and call + `BiomeSource.selectBiomeWithEdge`, checking both edge and no-edge behavior. +3. **Structural swamp edge:** The same invalid `0.45` fixture meant even the + supposed positive control was structurally ineligible. Use `0.6`, accept the + maximum allowed slope, reject one block steeper, and retain `0.45` as a + negative control for the inland constraint. +4. **Coast boundary:** #679 moved the ocean boundary from `0.35` to `0.37`; + `3fc9502b` (#681) narrowed beaches to continentalness `0.37..0.41` and height + at most `68`. Exercise the current named bounds, including ocean immediately + below the beach, both beach endpoints, inland immediately beyond it, and + slope/height exclusion. Inland water remains a non-beach control. +5. **Migrated Voronoi point:** `85d4f517` (#674) defines elevation centers at + explicit sites or structural height limits, not necessarily range midpoints. + The fixture sampled snowy mountains at height `184`, although its site is + at `112`. Convert each point's actual elevation center back to block height, + check eligibility, and require every point to select its own biome. +6. **Inland-high zone:** #679 moved the exclusive upper bound from `0.75` to + `0.72`. Exercise the current lower/upper bounds and their immediate outside + values instead of treating `0.72` as inland-high. The exact upper bound must + enter `mountain_core`. +7. **Coastal filler:** #681 deliberately reduced the minimum coastal layer from + six blocks to three, including the surface, and limited structural beaches + to three blocks above sea level. The old fixture forced a beach at height + `70` and expected sand five blocks below it. Obtain a real beach classification + at height `67`; check all layers for filler depths `1`, `3`, and `5`, the first + stone beneath them, and preservation of air, water, bedrock, and non-beach dirt. +8. **Shallow ocean floor:** #681 narrowed sand from water depth `<=12` to `<=5`; + the old depth-nine fixture is medium-depth clay by design. Check sand at + depths one and five, its filler extent, clay at six and thirty, and gravel + at thirty-one. No surface rule changes are needed. +9. **Representative spawn regions:** #681 deliberately lowered the broad + continental lowland base to `sea + 2.5` and introduced blended terrain + modifiers. The test conflated dry sea-level ground with water and demanded + climate-scale diversity from five origin-centered `256x256` windows. In the + original fixture, seed 42 has `0.305557` at-or-below-sea-level coverage; all + five windows contain zero dry-biome and mountain samples. That locality is + smaller than the configured 900-block continental and 1400-block macro-climate + spreads. Seeded Perlin fields also share zero noise at the origin, so changing + seeds does not make this small origin sample a broad climate survey. + +## Report Semantics + +`sea_level_coverage` retains its existing meaning: integer surface height at or +below sea level. New `water_coverage` counts surface heights strictly below sea +level, where surface placement has room for water above the terrain. A surface +at sea level is solid, dry ground, including sea-level-clamped wetlands. + +The new regression compares both report metrics to real `SurfaceBuilder` +placement over the original seed-42 region, requires wet and dry sea-level +columns to be present, and verifies the formatted report distinguishes them. + +The representative-seed test retains all five seeds and all numerical limits: + +- Local `256x256` origin regions: ocean `<=0.30`, water `<=0.30`, mountain `<=0.12`. +- Diversity survey: ocean `>=0.03`, forest `>=0.08`, wetlands `>=0.005`, dry biomes + `>=0.003`, mountains `>=0.002` across the same 327,680 survey samples. + +The diversity fixture samples a fixed `2048x2048` square from `(-1024,-1024)` at +eight-block intervals with reduction zero. It uses the existing climate capture +for full-detail columns, then reselects through `BiomeSource` using actual +one-block neighbor slopes. It does not use the snapshot's flat-slope assumption +or differences between distant survey points. No seed-specific coordinate search, +adaptive retries, expectation snapshots, or reduced thresholds are used. + +These are deterministic column/report tests, not a rendered-world or complete +chunk-decoration verification. diff --git a/modules/worldgen-overworld/src/biome_registry_tests.zig b/modules/worldgen-overworld/src/biome_registry_tests.zig index a26c17ff..0f77b2ad 100644 --- a/modules/worldgen-overworld/src/biome_registry_tests.zig +++ b/modules/worldgen-overworld/src/biome_registry_tests.zig @@ -103,8 +103,12 @@ test "BiomeDefinition fails continentalness out of range" { } test "BiomeDefinition fails ridge_mask too low" { - const def = getBiomeDefinition(.mountains);
