Доступны Inspector, диагностика и явный lifecycle development reload; сохранение состояния при reload проектируется отдельно. [Проверка Lua-модуля](docs/validation/lua-module.md) подтверждает Linux CPU-контракты и отключение модуля для C++-only проекта; Windows и независимый graphical/release профиль модуля остаются отдельными проверками.

+отделяет Debug от Release и
+запоминает версионированный fingerprint рецепта, исходников, Lua-деклараций,
+toolchain, шейдерных и runtime-входов. Повторное использование schema/package
+разрешено лишь после проверки полного manifest и схемы; испорченная или устаревшая
+генерация не выдаётся за cache hit. Переключение указателя на успешную генерацию
+атомарно; сбой сборки оставляет предыдущую доступной, но Inspector помечает
+метаданные устаревшими. Исходный каталог и копия повторно хешируются после native
+build и перед повторным использованием кэша или публикацией. Это обнаруживает сохранившееся изменение;
+запись и восстановление прежних байтов другим процессом того же пользователя во
+время чтения компилятором не исключены. Экспорт отдельно проверяет asset generations.

+Структурированные сообщения компилятора/Lua дополняют сырой лог. Для исходников

+позициями; внешний редактор запускается аргументами без shell. Четыре стартовых
+проекта комбинируют C++/Lua и 2D/3D. C++ остаётся rebuild-and-restart, а Lua
+development reload проверяет candidate и перезапускает script/world state, не
+сохраняя произвольное runtime-состояние.
+
+Autosave относится только к именованным dirty сценам Editor после двух секунд
+покоя. Он использует ревизию документа и прежний disk-hash conflict check, не
+перезаписывает внешний файл и не создаёт Undo-операцию. Неназванная сцена требует
+Save As; recovery journal работает независимо от autosave. Статусы видны в UI и
+через Editor MCP. Player и экспортная игра по-прежнему не имеют MCP.

+## Post-MVP checkpoint — P1 gameplay iteration
+
+P1 adds a complete-input native build stamp and a content-addressed `Scripts` copy.
+The package key binds configuration, recipe, source, Lua declaration, toolchain,
+shader and runtime artifacts. A second unchanged build reuses a verified schema
+and package generation without invoking SchemaExporter; CMake/Ninja still verify
+the native graph. Malformed/corrupt generations, modified headers/tools and
+detected source mismatches cannot publish a false hit. The live tree and staged
+copy are rehashed after native build and before reuse/publication; a same-user
+write-and-restore during compiler reads remains outside this check. Failed jobs
+preserve the previous successful pointer, while Inspector metadata becomes stale.
+
+Compiler and Lua output now produce bounded structured Console diagnostics with
+raw logs retained. Source opening accepts only project `Scripts` files and passes
+literal file/line/column arguments to the configured external editor. A real
+compile failure revealed that compiler paths pointed to the staged copy;
+`d7a7a7c` maps only the verified snapshot subtree back to project-relative
+source. The same correction retains a later actionable error after 250 unrelated
+warnings. Four runnable C++/Lua × 2D/3D starters are available in launcher and
+CLI; the existing scaffold default remains compatible. Named dirty scenes
+autosave after two idle seconds by default; unnamed scenes require Save As, and
+disk/revision conflicts retain the journal and never overwrite external edits.
+
+The [P1 dated dossier](validation/p1-iteration-2026-09-24/README.md) retains a
+clean-revision `6c2e8fa` Debug workflow with every raw command/profile. On the
+Ryzen 7 1700/RTX 2080 Ti Linux host, five unchanged builds had median 11.53 s,
+five changed-C++ builds 28.16 s, five changed-header builds 23.89 s, and five
+watched Lua reloads 0.502 s. All five unchanged builds reported a verified
+generation reuse. The 3,000-frame profile showed no growth in the explicit
+Vulkan allocation counter (15,787,008 bytes). A seeded 527-object synthetic
+scene reached 149.39 ms p95 wall time, dominated by CPU simulation/snapshot;
+this is a visible scalability issue, not a tiny-demo Release budget comparison.
+The historical exact-scene Release budgets were met in the earlier 2026-09-18
+record, but that evolving working-tree baseline does not certify the current
+revision. A quiet-host current Release rerun is pending.
+
+Linux focused cache, diagnostics, schema and workflow-math tests pass; a real
+failed-build replay now reports navigable `Scripts/Gameplay.cpp:73:2`. The
+[Lua-only Release result](validation/lua-release-2026-09-24/README.md) validated

+Release package validated and rendered 120 frames each after relocation with
+source paths unavailable; the [raw Windows report](validation/p1-iteration-2026-09-24/windows-4ac02ee/playable-report.json)
+records hashes and software Vulkan device identity. The later `d7a7a7c`

-# Add lights to a 3D scene
-
-Add a **Light** component to a scene entity. The entity's transform places a point
-or spot light; its rotation aims a spot light along local negative Z. A directional
-light uses the entity's orientation. Light colors and intensity contribute to the
-mesh's linear PBR illumination before tone mapping. Sprites and UI retain their
-unlit tint.
-
-The version-1 `faset.light` component has three `kind` values:
-
-| Kind | Position and direction | Useful fields |
-| --- | --- | --- |
-| `directional` | Direction from the entity transform | `color`, `intensity`, `casts_shadow` |
-| `point` | Position from the entity transform; illuminates every direction | `color`, `intensity`, `range` |
-| `spot` | Position and local negative-Z direction | `color`, `intensity`, `range`, `inner_angle`, `outer_angle` |
-
-Angles are radians. A spot's inner angle must not exceed its outer angle. Intensity
-must be nonnegative and range positive. `enabled: false` keeps the component in the
-scene without contributing light. The `shadow_priority` integer is reserved for the
-bounded local-shadow scheduler; it does not change brightness.
-
-In the current rendering checkpoint, one enabled directional light can cast the
-existing single-map shadow. Point and spot lights illuminate meshes but do not yet
-cast shadows. The [P3 lighting plan](https://github.com/emil28092005/Faset_Engine/blob/main/docs/superpowers/plans/2026-09-24-p3-lighting.md)
-tracks cascades and the bounded local-shadow atlas. A scene with no Light component
-keeps the legacy white sun so older projects retain their appearance. Adding any
-Light component, even a disabled one, turns off that compatibility fallback. If
-several directionals are enabled, Faset chooses the one with the smallest stable
-entity ID and reports a diagnostic for the others.
-
-## Author a point light through MCP
-
-Use `faset_schema` to inspect the current field IDs, then send a `faset_scene_edit`
-batch with the document ID, current revision, and target entity ID. For example:
-
-```json
-{
-  "document": "REPLACE_WITH_DOCUMENT_ID",
-  "revision": 4,
-  "idempotency_key": "add-red-point-light",
-  "operations": [{
-    "op": "component.add",
-    "entity": "REPLACE_WITH_ENTITY_ID",
-    "type": "faset.light",
-    "fields": {
-      "kind": "point",
-      "color": [1, 0.15, 0.1, 1],
-      "intensity": 8,
-      "range": 6
-    }
-  }]
-}
-```
-
-Move the entity with its Transform component. `component.add` fills any omitted
-light fields from the version-1 schema; use `component.set` for later edits. See
-[MCP and command line](mcp.md) for revision and retry handling.
-
-## Supply lights directly from C++
-
-When building a `faset::render::Snapshot` yourself, set
-`authored_lights_present` to suppress the compatibility sun in a local-only scene.
-Provide a stable ID for each light so future shadow scheduling remains independent
-of submission order.
-
-```cpp
-faset::render::Snapshot snapshot;
-snapshot.authored_lights_present = true;
-
-faset::render::LocalLight point;
-point.kind = faset::render::LocalLight::Kind::Point;
-point.stable_id = "level/torch";
-point.position = {-2, 1.5f, 0};
-point.color = {1, 0.3f, 0.1f, 1};
-point.intensity = 8;

Thus an old scene without light components keeps its previous appearance, while a local-only scene or explicitly disabled sun does not receive an unintended directional light. Low-level callers may set the flag to request a dark scene without authoring metadata. Local lights are ordered by stable ID to prevent reordering from changing atlas allocation or results.

 headers and cached Slang, with SDL X11/Wayland disabled. No system graphics packages
 were installed. This proves linkage and CPU validation, not graphics compatibility.

+The [Release execution record](lua-release-2026-09-24/README.md) closes the
+Linux offscreen export gap above. At source commit `4331857`, a Release Editor
+exported the checked-in Lua-only sample into a disposable Unicode-path project.
+The package was relocated, the source project path was hidden, and its Player
+validated and rendered 120 frames on an NVIDIA GeForce RTX 2080 Ti with driver
+595.84 and Khronos validation enabled; zero validation errors were reported.
+The package manifest has `lua_enabled: true`, declared Lua source and its license,
+and no project C++ gameplay source. The five focused Release Lua/schema tests
+passed. This verifies an offscreen run on Linux; a separate physical Windows GPU
+and manual window interaction have not been tested by this record. Windows
+SwiftShader execution is configured in CI and needs a passing run before it is
+claimed as covered.

+# Lua-only Release game: relocated execution
+
+This is a local Linux result for source revision
+`433185717e1f324acb6eaf186818589d11697453` on 2026-09-24. The
+[machine-readable report](report.json) records the exact source input hashes,
+Release package, Editor binary hash, command arguments and elapsed times. The
+Editor itself was built with the `linux-release` preset. The exported Player
+and package also identify their configuration as Release.
+
+| Check | Observed result |
+|---|---|
+| Disposable source | `examples/lua` copied to a Unicode-path temporary project outside the engine tree |
+| Package | `lua_enabled: true`; 32 hash-checked files, including Lua gameplay source and `Notices/lua/LICENSE.txt`; no project `Gameplay.cpp` or `.hpp` |
+| Relocation | Generation copied outside the project/engine; original project path hidden before Player launch |
+| CPU validation | Packaged Player `--validate` succeeded from an unrelated empty working directory |
+| GPU execution | 120/120 headless 1280×720 frames, 0 validation errors |
+| Device | NVIDIA GeForce RTX 2080 Ti; proprietary driver 595.84, Vulkan 1.4.329; selected-device details in the report and [Vulkan probe](vulkaninfo-summary.txt) |
+| Image | Four expected scene colors, including cyan player and gold collectible; raw [PPM](lua.ppm) SHA-256 `e2f4c3b84de75dadd2e31d388d0ba51abc1861f1ec76eb7ba51a4a2dcac720a7` |
+| Focused Release CTest | 5/5: `lua_contracts`, `lua_safety_contracts`, `lua_cli_contracts`, `lua_player_reload`, `build_schema_publication` |
+
+The [manifest](lua-manifest.json) binds the package file checksums. The
+[Player profile](lua-profile.json) contains all 120 per-frame samples and
+resource/timing definitions; the [validate](lua-validate.json),
+[render](lua-run.json) and [export](lua-export.json) logs retain raw process
+results. The [PNG preview](lua.png) is a lossless conversion of the checked
+PPM.
+
+The verifier also confirmed a clean Git source tree, rejected undeclared
+package files and unexpected C++ script files, classified the selected device
+as physical, and found the sample Lua `on_start` log in the relocated run.
+
+To repeat this check from a built checkout, choose a **new, empty** output
+directory:
+
+```sh
+cmake --preset linux-release
+cmake --build --preset linux-release --target faset_editor --parallel 4
+python3 tools/verify_playable_exports.py --editor build/linux-release/faset_editor \
+  --output .cache/lua-release-check --only-lua
+cmake --build --preset linux-release --target faset_player faset_schema_exporter \
+  faset_lua_tests faset_lua_safety_tests faset_build_schema_tests --parallel 4
+ctest --test-dir build/linux-release --no-tests=error --output-on-failure \
+  -R '^(lua_contracts|lua_safety_contracts|lua_cli_contracts|lua_player_reload|build_schema_publication)$'
+```
+
+The render used the Player's synthetic fixed timestep and offscreen Vulkan
+presentation. It does not establish manual window interaction or physical
+Windows GPU compatibility. The separate
+[Windows graphics run at `4ac02ee`](https://github.com/emil28092005/Faset_Engine/actions/runs/35937433040)
+passed 61/61 CTests and relocated all three Release games under pinned SwiftShader.
+The Lua-only package validated and completed 120 offscreen frames with its source
+project paths hidden. Its device is a **software** Vulkan implementation; the
+Khronos validation layer was not active on that Windows worker. The
+[P1 dossier's Windows report](../p1-iteration-2026-09-24/windows-4ac02ee/playable-report.json)
+retains the source/package identities and result. This does not establish
+physical Windows GPU compatibility.

+# P1 gameplay iteration: measured Linux workflow
+
+The [unaltered version 2 workflow report](report.json) was produced by a clean
+`6c2e8fa80036315a695f67f3c53524165fb4b10a` checkout on 2026-09-24.
+It used disposable copies of the checked-in `collect-3d` and `examples/lua`
+projects. Every sample, process log and Player profile is retained under `raw/`;
+[the run log](workflow.log) shows the order and completion. The report identifies
+each input revision by SHA-256, and records all command arguments, phase labels,
+configuration and dirty-tree state. Its SHA-256 is
+`fd463c0cd12eed0a22143aa68bd732386804b0df4ecb2a3d9caa26f59dcfe6e2`.
+
+The original report's `toolchain.slang` is `null` because that version looked
+for `slangc` on `PATH`, while CMake used a configured executable. A **separate**
+[post-run provenance supplement](provenance.json), generated after commit
+`abd8c21` from the surviving disposable [compressed CMake cache](CMakeCache.txt.gz), hashes
+the selected CMake, Ninja, C/C++ compiler, Slang, Editor and UI-probe binaries.
+It binds to the original report hash and records both script revisions. The
+measured report was not rewritten. Subsequent workflow runs include these
+identities in their report directly. `4ac02ee` changed only the Windows CI export
+fixture location; neither follow-up is presented as the measured code revision.
+
+## Measurement conditions and results
+
+The host ran Linux 7.0, Ryzen 7 1700, 32 GiB RAM, RTX 2080 Ti and NVIDIA 595.84.
+The disposable project used Debug, Clang 21.1.8, CMake 4.2.3, Ninja 1.13.2 and
+Slang 2026.18. The Player rendered offscreen Vulkan at 1280×720 with validation
+active and full-frame readback. The run did not overlap the separate P3 GPU sweep.
+Build times still depend on ambient CPU load, filesystem cache and prepared
+dependencies. The `cold` row means an empty project `.faset` cache, **not** a cold
+OS page cache or a first dependency download.
+
+| Observation | Samples | Median | Nearest-rank p95 | Scope |
+| --- | ---: | ---: | ---: | --- |
+| Initial configure and native build | 1 | 106.01 s | — | Disposable Debug project |
+| Unchanged build | 5 | 11.53 s | 13.12 s | All five reused the verified schema/package generation |
+| Changed `Gameplay.cpp` build | 5 | 28.16 s | 30.33 s | One warm-up edit excluded |
+| Changed `Gameplay.hpp` build | 5 | 23.89 s | 25.51 s | One warm-up edit excluded |
+| Watched Lua edit to reload log | 5 | 0.502 s | 0.504 s | Persistent Player; includes watcher polling |
+| First completed offscreen Player frame | 5 | 0.284 s | 0.333 s | From `main()`; excludes OS loader and window presentation |
+| Synthetic Editor input to rendered state | 100 | 13.97 ms | 18.03 ms | Ten warm-ups; offscreen retained-UI frame, not input-to-photon |
+
+The intentional C++ compile failure took 10.00 s and the corrected recovery
+build 19.93 s. The failed job preserved its prior successful build pointer.
+The run also imported the small Blender bundle cold and cached in 49 and 52 ms,
+respectively; Editor process startup dominates that tiny asset sample, so those
+two values do not establish import-cache speedup. The raw
+[failed-build job](raw/build_failure-01-stdout.txt) exposed a navigation defect:
+the compiler named the staged source copy, and the original structured
+diagnostic omitted `file`. A later fix maps only the verified staged `Scripts`
+subtree to project-relative source. A [real failed-build replay](diagnostic-replay.json)
+with the corrected Editor returns `Scripts/Gameplay.cpp`, line 73, column 2.
+The `build_diagnostics` test also covers project-contained snapshot paths and
+Windows drives; `build_schema_publication` verifies that an error after 250
+third-party warnings survives the 200-row diagnostic limit. These are separate
+from this unmodified measurement.
+
+Follow-up `54d1bae` rehashes both the live source and the staged copy after
+native build and before reuse/publication. A fixture changes the staged C++
+header during schema export; the build fails and retains the last-good pointer.
+The copy is content-verified at those boundaries, not sealed against a same-user
+write-and-restore during compiler reads.
+
+The [3,000-frame lifecycle profile](raw/cpp-3000-frame-lifecycle.json) completed
+with zero Vulkan validation errors. Maximum explicit Vulkan allocation was
+15,787,008 bytes in both frames 101–200 and 2901–3000, a measured growth of zero;
+the live texture count remained one. These counters exclude driver-internal
+memory and do not prove absence of all resource leaks.
+
+The generated [527-entity scene](raw/generated-512.scene.json) adds 512 seeded
+copies to the 15-entity source and ran for 240 offscreen frames with zero Vulkan
+validation errors. Its [raw profile](raw/generated-512-profile.json) reports p95
+frame wall 149.39 ms, simulation 48.19 ms, scene snapshot 68.12 ms, renderer call
+36.51 ms and GPU timestamp 0.911 ms. It exposes a significant CPU scaling cost
+in this synthetic content; it is not a typical-game benchmark or a Release budget
+failure for the tiny checked-in sample.
+
+## Reference budgets and coverage
+
+The [2026-09-18 Release reference baseline](../linux-release-2026-09-18/README.md)
+measured the **exact** `collect-2d` and `collect-3d` packaged scenes on this host,
+at 1280×720 with validation/readback. Its 240-frame p95s met the initial tracking
+budgets: frame 2.684/2.732 ms versus ≤4; GPU 0.579/0.600 ms versus ≤1; readback
+0.633/0.608 ms versus ≤1; simulation 0.258/0.300 ms and snapshot 0.215/0.257 ms
+versus ≤0.5 each. Explicit allocations were about 15.02/15.06 MiB versus
+≤20 MiB; first-frame startup from `main()` was 265.5/260.8 ms versus ≤500 ms.
+That baseline was an evolving earlier working tree. Its values are **historical**
+and are not compared with this Debug workflow's timing.
+
+The [fresh clean combined P1/P3 Release reference](final-release/README.md) at
+`4a3453e` repeats these exact scenes on the same physical RTX 2080 Ti, now with
+120-frame source-hidden relocation checks for C++ 2D/3D and Lua-only, plus
+sequential 240-frame C++ 2D/3D profiles. The frame, GPU, readback, simulation,
+snapshot and startup tracking budgets all pass. Explicit allocations instead
+reach **43.022/43.118 MiB**, above the former ≤20 MiB budget because the new
+renderer eagerly retains a 16 MiB sun atlas and a 16 MiB local atlas in both
+scenes. The 2D sample casts no sun shadows and neither sample uses local shadow
+faces. This is a measured tracking-budget miss, not a failed export or a reason
+to redefine the counter silently. The linked dossier retains exact values,
+atlas breakdown, raw profiles and source/toolchain provenance.
+
+The [Lua-only Linux Release dossier](../lua-release-2026-09-24/README.md) separately
+records a relocated package that validated and rendered 120 frames after hiding
+its source project, with 0 validation errors. The final fixture placement was
+checked in clean-revision [`4ac02ee` Windows graphics CI](https://github.com/emil28092005/Faset_Engine/actions/runs/35937433040):
+61/61 CTests passed on pinned SwiftShader, the real 2D/3D Release export
+integration passed, and **all three** relocated Release games (`collect-2d`,
+`collect-3d`, Lua-only) validated and rendered 120/120 frames with source paths
+unavailable. The [Windows playable report](windows-4ac02ee/playable-report.json)
+contains package and source hashes, device identity, result details and capture
+checksums; [integration results](windows-4ac02ee/integration-result-2.json),
+[integration manifests](windows-4ac02ee/integration-manifest-2.json),
+[Vulkan probe](windows-4ac02ee/vulkan-probe.json) and
+[toolchain record](windows-4ac02ee/toolchain.json) preserve representative raw
+evidence. The parallel [native/manual CI](https://github.com/emil28092005/Faset_Engine/actions/runs/35937433211)
+passed on Linux and Windows. This is **software** Vulkan; Windows did not have an
+active Khronos validation layer (`validation_enabled: false`), and no physical
+Windows GPU/driver performance claim follows. The later [combined P1/P3 Windows
+graphics CI](https://github.com/emil28092005/Faset_Engine/actions/runs/35942307579)
+at `87230f3` passed 74/74 CTests, including real diagnostic navigation, real
+Release export integration and all three relocated games. The physical-GPU
+Linux reference above had active validation.
+
+## P1 acceptance record
+
+| Area | Evidence and current limit |
+| --- | --- |
+| Lua | Linux native and Release [relocated Lua result](../lua-release-2026-09-24/README.md), repeated in the [clean combined three-game Release reference](final-release/README.md); Windows CPU/SwiftShader [combined 74-test suite](https://github.com/emil28092005/Faset_Engine/actions/runs/35942307579) and [relocated Lua-only Release report](windows-4ac02ee/playable-report.json), 120 completed frames. |
+| Cache and rollback | [Five verified hits](report.json), `build_cache` and `build_schema_publication` contracts for headers, toolchain, schema/shader corruption and source races; the raw failed/recovered build retains the previous pointer. |
+| Diagnostics | `build_diagnostics` fixtures cover Clang, clang-cl, Lua, Unicode and unparseable output. The raw real failure above found a staged-source mapping gap; [the replay](diagnostic-replay.json), parser case, warning-flood case and real BuildService integration assertion cover the correction. |
+| Starters/navigation | [Four runnable C++/Lua × 2D/3D starters](../p1-starters-linux-2026-09-24.md) plus launcher/CLI and source-open tests. |
+| Autosave | `editor_session_settings`, UI tests and [workspace behavior](../../manual/editor/workspace.md#create-and-save-a-scene): idle coalescing, unnamed Save As, external/revision conflicts, Undo and recovery. |
+| Iteration | This Debug report, 179 raw files, 3,000-frame and seeded larger-scene profiles, plus the [clean combined Release reference](final-release/README.md) with three relocated games and exact 2D/3D budgets. The allocation budget miss is recorded; no CI timing gates. |
+| Documentation | The English Manual describes build/reload, templates, navigation, autosave and profile interpretation; strict MkDocs and full platform test totals are recorded in the implementation journal. |
+
+The [profiling guide](../../manual/editor/profiling.md#measure-editor-c-and-lua-iteration)
+documents how to repeat the run and interpret its deliberately distinct timing
+labels. C++ hot reload, state-preserving Lua reload and Player-world MCP are not
+part of this P1 contract.

+`4a3453e2b1868555d833f578d43f48b8bc47d41a`. The real Release Editor

+[3D manifest](evidence/collect-3d-manifest.json), and
+[Lua manifest](evidence/lua-manifest.json) retain input, package and binary
+hashes. The [toolchain supplement](provenance.json) binds the unmodified report
+and 240-frame summary to the exact Editor, CMake, Ninja, Clang and Slang
+binaries. The verifier recorded a clean checkout at its start, and the second
+profiles used the same relocated Player binaries.
+
+| Relocated package | Runtime | Frames | GPU validation | Source paths hidden |
+| --- | --- | ---: | --- | --- |
+| `collect-2d` | C++ | 120/120 | active, 0 errors | yes |
+| `collect-3d` | C++ with Blender asset | 120/120 | active, 0 errors | yes |
+| `lua` | Lua-only | 120/120 | active, 0 errors | yes |
+
+The two **same relocated C++ executables** then ran a second, sequential
+240-frame profile. For each run, the disposable source-project paths were again
+hidden and restored afterward. These exact 2D/3D samples used default Direct
+visibility and temporal Off, 1280×720 offscreen Vulkan, synchronous readback,
+the active Khronos validation layer and synthetic fixed-step simulation. No
+frame was discarded as a warm-up: the table uses nearest-rank p95 over all 240
+completed frames, including the first. Both profiles report zero validation
+errors. Raw [2D](reference-240/collect-2d-profile-240.json) and
+[3D](reference-240/collect-3d-profile-240.json) profiles, exact
+[2D invocation](reference-240/collect-2d-run-240.json) and
+[3D invocation](reference-240/collect-3d-run-240.json), and the
+[machine-readable budget comparison](reference-240/reference-summary.json)
+support every value below.
+
+| Exact-scene observation | Initial P1 tracking budget | 2D | 3D |
+| --- | ---: | ---: | ---: |
+| Frame wall p95 | ≤4 ms | 2.694 ms | 3.036 ms |
+| GPU timestamp p95 | ≤1 ms | 0.573 ms | 0.617 ms |
+| Readback CPU p95 | ≤1 ms | 0.559 ms | 0.561 ms |
+| Simulation p95 | ≤0.5 ms | 0.242 ms | 0.300 ms |
+| Scene snapshot p95 | ≤0.5 ms | 0.197 ms | 0.288 ms |
+| `main()` to first frame | ≤500 ms | 295.4 ms | 248.3 ms |
+| Maximum explicit Vulkan allocation | ≤20 MiB | **43.022 MiB — miss** | **43.118 MiB — miss** |
+
+The memory miss is real, not a profile rounding artifact: 2D used 45,112,032
+bytes and 3D used 45,212,272 bytes, while the earlier threshold was 20,971,520
+bytes. Each run counted a **16 MiB sun atlas and a 16 MiB local-light atlas**
+inside the live Vulkan allocation total. The 2D sprites produced no sun-shadow
+raster work; the 3D meshes rendered four sun cascades. Neither sample used a
+local shadow face. Both 2048² D32 atlases are currently allocated when the
+Renderer is created, even when the scene never uses them. The remaining explicit
+allocations were 11.022 MiB (2D) and 11.118 MiB (3D). Lazy local-atlas
+allocation is a sensible follow-up, but alone it would still leave the 3D
+scene above 20 MiB with its current 2048² sun atlas. We have kept the physical
+counter and shadow resolution intact and recorded the miss rather than silently
+changing either to satisfy an older threshold. The 20 MiB value is an initial
+**tracking budget** for tiny pre-P3 scenes, not a functional export gate; any
+revised shadow-memory budget needs its own measured baseline.
+
+The Lua run establishes relocated Release execution, not a 2D/3D latency
+budget. The [2026-09-18 Release reference](../../linux-release-2026-09-18/README.md)
+used these scenes on the same GPU but an evolving earlier working tree; its
+numbers are historical context, not this clean combined revision. This run
+measures small scenes on one active Linux desktop and one driver (NVIDIA
+595.84). GPU timestamps exclude CPU work, `renderer_readback_cpu` is a
+map/copy/unmap duration inside the renderer call, and the explicit allocation
+counter excludes driver-internal memory. It does not establish production-game
+scaling, whole-process VRAM usage, display-paced FPS, physical Windows GPU
+performance or absence of all leaks.
+
+## Reproduce and inspect
+
+From this repository with the dependencies configured:
+
+```sh
+cmake --preset linux-release
+cmake --build --preset linux-release --target faset_editor --parallel 2
+python3 tools/verify_playable_exports.py \
+  --editor build/linux-release/faset_editor \
+  --output /tmp/faset-p1-release-new \
+  --standalone-root /tmp/faset-p1-packages-new \
+  --include-lua
+python3 docs/validation/p1-iteration-2026-09-24/final-release/profile_exact_scenes.py \
+  --verification /tmp/faset-p1-release-new/report.json \
+  --output /tmp/faset-p1-release-new/reference-240
+```
+
+Use **new, empty** output and standalone directories. The second helper
+refuses an incomplete or dirty-tree verifier report, hides the disposable
+source projects during each 240-frame run, checks exact settings and validation,
+then restores them. The original [verifier log](verifier.log),
+[240-frame log](reference-240.log), raw 120-frame profiles for
+[2D](evidence/collect-2d-profile.json),
+[3D](evidence/collect-3d-profile.json) and
+[Lua](evidence/lua-profile.json), PPM captures, and the
+[SHA-256 file list](SHA256SUMS.txt) are retained here. The
+large disposable native build directories and relocated executable packages
+remain under `/tmp`; their input, manifest and executable hashes are in the
+reports.
