chore: checkpoint web Blender migration source, tools and docs

Accumulated uncommitted work: GHOST Web backend, WebGL/GPU web layer,
web workflow engine and protocol, tooling, docs and task records.
Large generated evidence, user-testing archives, build snapshots and
imported test assets remain untracked.

2026-10-26 B3 read-error symmetry: current v2 candidate passes minimal and ABB production reader-error/partial-retention cases with unchanged Main/history; evidence retained under validation-20261026-b3-transfer-ui/current-error-v2. Native-drop owner settle/prompt remains the only active transfer interaction residual.
2026-10-26 B3 owner trace source binding: wm_window_web_scene_changed in wm_window.cc:3829-3844 advances the web input epoch during post-open scene propagation; the drop handler observes owner 1→2 before type-9. Stale-owner cancellation remains intentional; next action is an explicit owner-stable barrier.
2026-10-26 B3 owner trace: native-drop staging observes ownerGeneration 1 on initial focus frame, then 2 on the post-open scene/input frame; upload reaches Worker but stale owner protection prevents type-9 dispatch. This is retained as the precise residual; no owner-loss bypass claimed.
2026-10-26 B3 owner-stable v2: drop handler captures owner after canvas focus; new candidate build_web_main_desktop/b3-transfer-drop-owner-stable-v2-20261026/candidate.json passes all four current-bound transfer file/folder cases. Native-drop positive remains owner-settle sensitive and prompt confirmation stays unclaimed; evaluator PARTIAL_BLOCKED/30.1 with 18 blockers.
2026-10-26 B3 native-drop follow-up: transfer remains 4/4 current-bound PASS after pointer-move focus stabilization. Native-drop v7 cancellation/type-9 receipts remain historical partial evidence; current reruns exposed owner-generation settling and prompt-key delivery instability, so prompt confirmation/UndoRedo/SaveReopen stay unclaimed.
2026-10-26 B3 transfer/drop v7 update: current pointer-move boundary closes minimal/ABB file and folder-restore transfer gates (4/4 current-bound). Native drop minimal/ABB cancellation and type-9 delivery remain PASS; unsaved prompt confirmation, UndoRedo and SaveReopen remain pending. Evaluator remains PARTIAL_BLOCKED/30.1 with 18 blockers; B3 in_progress/NOT_CLAIMED.
2026-10-26 B3 transfer/drop current v7: tests/golden/WBV2-P1424-001/continuation-20261026-b3-transfer-drop-validation.json; candidate build_web_main_desktop/b3-transfer-drop-result2-20261026/candidate.json (SHA bfaf9117d6dd0aa0be71de54d45a9af6061d75b9a923fcc20049cf3bd1d2d0b6). Chromium minimal/ABB native-drop cancellation and positive staging/type-9 delivery PASS; positive native unsaved prompt remains pending. Current transfer receipts: minimal/ABB file PASS, minimal folder+restore PASS, ABB folder PASS, ABB restore modal-start FAIL; evaluator current eligible 3/4, PARTIAL_BLOCKED/30.1 with 18 blockers. B3 remains in_progress/NOT_CLAIMED; next focus is the single ABB restore modal boundary.

2026-10-21 modes/GLB: latest tests/golden/WBV2-P1424-001/mesh-modes-glb-20261021/manifest.json. Open-grid Collapse/Unsubdivide/Dissolve Main lifecycle and invalid/no-mutation cases PASS; canonical boundary/geometry/UV/normal/custom weights and matrices EXACT desktop. Fixed GLB V convention and silent named-attribute loss; three production UI exports pass desktop world-triangle/UV/normal/PBR checks (max position1.20e-7, UV2.99e-8, normal5.97e-8, PBR0). Generic fixture_weight is explicitly reported as GLB loss, preserved in .blend. Typecheck/9 GLB units/frontend package PASS, native reused. Next B hierarchy fixture/UI/function/lifecycle then C combined recovery. A remaining cancellation/resource/cache-recovery, release/official baseline not claimed; no live builder.
2026-10-21 simplify target/report: latest tests/golden/WBV2-P1424-001/simplify-target-report-20261021/manifest.json.

WASM/typecheck/package PASS; ui=web target4032 preview/cancel, target8064 apply/report/cache/history/reopen and five native fail-closed cases PASS; screenshot reviewed and desktop saved-Main canonical hash EXACT. A remains PARTIAL for wider boundaries/modes/GLB/cancellation/resource/cache recovery; B PARTIAL, C NOT_VERIFIED, release/acceptance NOT_CLAIMED. Next same task: open-boundary/mode matrix and production GLB desktop readback using existing paths; no live builder.
2026-10-21 LOD: latest tests/golden/WBV2-P1424-001/lod-current-main-20261021/manifest.json. Current-Main generation/clone revision, actual output budgets, cache ownership/status fixed; native fan replaced with Blender tessellation and identity decimate no longer rotates loops.

LOD 8064/4032/2016 counts and position/index hashes EXACT desktop; saved Main full canonical geometry/attributes EXACT. No active build; A PARTIAL (target triangles/loss report and broader matrix/cancellation/cache-recovery/GLB), B PARTIAL, C NOT_VERIFIED, release/acceptance NOT_CLAIMED. Next same task: target-triangle UI/native budget plus simplify report; keep original scope.
2026-10-20 native-decimate-attributes: latest tests/golden/WBV2-P1424-001/native-decimate-attributes-20261020/manifest.json. PRESERVE custom attribute loss fixed using existing full-Mesh/BMesh converters and native decimate kernels, one Main commit with existing rollback/history. WASM/native-decimate-attributes-final-20261020/typecheck PASS; Chromium 16128→8064 lifecycle and four stale/invalid preview/direct-apply negatives PASS with exact unchanged snapshots.

A remains PARTIAL for target-triangle/loss/cache UI, broader modes/boundaries/budget/GLB; B PARTIAL, C NOT_VERIFIED, acceptance/release NOT_CLAIMED. Next same task: current-Main LOD generation and cache/budget UI gates; no live builder, reuse passing source/fixture evidence.
2026-10-20 main-preview: latest tests/golden/WBV2-P1424-001/mesh-simplify-20261020/main-preview/manifest.json; all tracked builds terminal.

Chromium current-Main preview/cancel/apply/undo/redo/save/reopen PASS, cancellation desktop geometry/attributes hash EXACT. Applied saved blend loses fixture_weight under PRESERVE: attribute protection FAILED, A PARTIAL. B PARTIAL, C NOT_VERIFIED, release/acceptance NOT_CLAIMED. Candidate preview-current-main-20261020 contains frontend fix; C++ guards/RNA/shader fixes still require WASM integration. Next same task: replace lossy decimate Main replacement through existing native modifier implementation, retain all prior residuals.
2026-10-20 mesh-simplify checkpoint: tests/golden/WBV2-P1424-001/mesh-simplify-20261020/manifest.json. Production Chromium prerequisite PASS (151.0.7922.137, 1440x900, isolated, zero request/console errors, exact candidate WASM hash). High-triangle generator and UI preview/cancel/apply/history/save/reopen test added, full flow NOT_RUN; first fixture attempt failed with old native RNA argument handling. Existing native build now updates desktop binary at -j2, session44270/pid463745/startIdentity38138960; poll live process/result before any retry. Requested build_blender_5.2.0 cache still points to missing old source. A PARTIAL, B PARTIAL, C NOT_VERIFIED, acceptance NOT_CLAIMED; original scope and residuals retained.
2026-10-20 recovery: tests/golden/WBV2-P1424-001/recovery-20261020/manifest.json; active index restored through generator, handoff artifact-path handling fixed, 5 checker cases passed. Control-plane/health/context passed; historical handoff remains FAILED (63/313 artifact hashes drift). Prior native candidate hashes match, no rebuild or acceptance claim. A mesh simplification and B hierarchy remain PARTIAL pending current-candidate proof; C combined workflow remains NOT_VERIFIED.
continuationNotes recovery-20261020: unique resume task WBV2-P1424-001; follow fresh recovery task-context, locate existing mesh/LOD/Main/UI receipts for priority A and compare fixture/input hashes before a focused production gate. Preserve all previous residuals and nextTask=null; no product coverage increment.
Scheduler: reuse wbv2-implementation.service; current state is authoritative at tests/golden/WBV2-P1424-001/unattended-implementation/state.json.
Latest matching candidate: build_web_main_desktop/compute-host-cleanup-20261012/candidate.json; manifest: tests/golden/WBV2-P1424-001/compute-host-cleanup-20261012-manifest.json. Isolated Main destruction now releases compute host even when native destruction reports an error; native pair reused. Runtime unverified; all prior residuals retained.
Latest scheduler handoff: tests/golden/WBV2-P1424-001/scheduler-handoff-20261012-manifest.json; preserve latest foreground reference in bounded payload, reconcile stale claims once, resume concrete residuals. No new business completion or verification claimed.
Validation: NOT_RUN; acceptance: NOT_CLAIMED; deployment: not performed.
Known residuals: WM/GPU focus and depth recovery, GP placement/pressure/tilt, NLA Time Warp/Transition/Meta evaluation, browser runtime, undo/redo, save/reopen.
Context policy: historical continuation is archived at docs/status/archive/WBV2-P1424-001-history-20261010.md; read it only for a specific historical cycle or handoff. Cycle reports remain under tests/golden/WBV2-P1424-001/unattended-reports/ and are read by exact path only.
Scheduler fixes: task context budget restored below limit; stale camera preset line-34 handoff replaced; context-budget interruptions now rotate immediately while preserving pending and old candidates.
Scheduler throughput tuning: recent turns spent 140–442s with 20–51 source reads and no production changes. Defaults now bound source investigation at 12 reads/210 active seconds, idle at 300s, and source progress at 300s; minimum read floor remains 8. This changes rotation speed only, preserves pending/old candidates, and does not claim feature completion.
Scheduler wait tuning: strategy-rotation pause is capped at 30s instead of 300s, so the third wait can trigger bounded focus rotation promptly even when a retryAt is far in the future; pending, old candidates and service ownership remain unchanged.
2026-10-10 latest source delivery: cycle4355 added null-area fail-closed guards to both WebGL depth readback paths; native incremental build and matching candidate depth-area-guard-20261010 completed, validation remains NOT_RUN.
2026-10-10 latest source delivery: cycle4364 mapped legacy browser keycodes 61/173 to native Equal/Minus for Ctrl+=/Ctrl+- View3D zoom; matching native candidate legacy-zoom-keycodes-20261010 completed, validation remains NOT_RUN.
2026-10-10 latest source delivery: cycles4355/4369/4370 aggregate F3 abort ownership, GPU depth recovery and null-area guards into f3-gpu-recovery-20261010; native build/package succeeded after race-protected retry, validation remains NOT_RUN.
2026-10-10 latest source delivery: cycle4374 added F3 error-only terminal feedback cleanup; frontend candidate f3-terminal-feedback-20261010 reused the matching native pair, validation remains NOT_RUN.
continuationNotes batch=context-archive-20261010: replaced the 70 KB status history with this bounded index; full history copied byte-for-byte to the archive; no task/parent/nextTask/pending mutation and no feature validation run.

2026-10-24 B3 server closure: tools/web/server-operator-job-server.mjs now fingerprints Blender executable size/mtime in the RNA schema cache key, preventing stale schema/build reuse after same-path binary replacement; malformed JSON requests return HTTP 400 before job publication. web/app/src/app/App.tsx clears prior native workflow artifact URLs before each new job, preventing stale download publication after failure/cancel. Runtime hashes: server e08a0b4427eb870f908cc35ab5872a519f16ca7b1cdf88fa4c030667112621c6, UI d1638b42f4f482a2b3d06164a1fa6133947b2cfe5e750dadcf3972fd13f1829f; report/manifest tests/golden/WBV2-P1424-001/server-schema-fingerprint-20261024.md and server-schema-fingerprint-20261024-manifest.json. Validation NOT_RUN, acceptance NOT_CLAIMED, B3 remains in_progress; Chromium prerequisite and native Open/Server Operator UI evidence remain blocked.
2026-10-24 B3 IO route audit: current native WebEngine IO reaches web_engine_blend_main_obj_io for the local Main mutation path, while the static UI registry still advertises GLTF/GLB/STL/PLY imports as LOCAL. OBJ remains the bounded native import/export case; GLB export is a separate browser workflow. Route reconciliation is pending, validation NOT_RUN, acceptance NOT_CLAIMED. Handoff: tests/golden/WBV2-P1424-001/continuation-20261024-b3-io-route-audit.json.
2026-10-24 B3 IO route guard: web/app/src/app/App.tsx now filters the runtime import registry to OBJ and sends only OBJ file selections to the native import path; unsupported static-registry formats are excluded from the picker and fail closed with IO_FORMAT_UNSUPPORTED. UI source hash 1b07d578ec7d78cda9df46a2bce117d5ceb51786945ac7af5e43df551fb623cc; report/manifest tests/golden/WBV2-P1424-001/b3-io-route-guard-20261024.md and b3-io-route-guard-20261024-manifest.json.

Validation NOT_RUN, acceptance NOT_CLAIMED; headless export and remaining B3 runtime gates remain pending.
2026-10-24 B3 export source correction: native-workflow-blender.py explicitly requires a non-background window/area/region for EXPORT, so the proposed headless launch was reverted. GUI/Xvfb remains required for EXPORT; managed-property pre-allocation validation remains. Corrected source hash bf772ff2b097074d434f2b8845250764f3006399d6a62cf12243909119ded51e; report/manifest tests/golden/WBV2-P1424-001/b3-native-export-window-20261024.md and b3-native-export-window-20261024-manifest.json.

Validation NOT_RUN, acceptance NOT_CLAIMED; repeated provider and Chromium runtime gates remain pending.
2026-10-24 B3 Server Operator cancel cleanup: cancellation now catches process-tree cleanup errors, releases workspace, and keeps terminal CANCELLED with explicit cleanup error detail so finishJob cannot publish a late result.

2026-10-24 B3 F3 Server Operator cancellation: App.tsx now creates an AbortController for SERVER_NATIVE F3 execution, displays Cancel, and keeps AbortError separate from COMMAND_FAILED diagnostics; WebEngineClient.invokeFeatureRoute forwards the signal into submitServerOperatorJob, allowing provider cleanup and no late Main/success publication. UI hash fc81ba0e44f408659dcb9fea373a2dac5fd5919dc3118e426e46a9eafc681df3; engine hash 3c21dc3a2260f5b62cea8a07c5376309ddf40125782c04262d9560e95c828af3; report/manifest tests/golden/WBV2-P1424-001/b3-f3-server-cancel-20261024.md and b3-f3-server-cancel-20261024-manifest.json.

Validation NOT_RUN, acceptance NOT_CLAIMED; Chromium/Xvfb and all B3 runtime/readback gates remain pending.
2026-10-24 B3 F3 cancellation isolation: App.tsx now limits web-engine-native-modal-cancel broadcasts to Desktop/local native cancellation; SERVER_NATIVE Escape cancellation only aborts its own request, preventing interference with an unrelated viewport modal.

2026-10-24 B3 OBJ operator context routing: Blender 5.2 WM_OT_obj_import/WM_OT_obj_export use WM_operator_winactive, while WebEngine OBJ IO uses web_engine_blend_main_obj_io; direct F3 entries are now UNAVAILABLE and the existing browser/native file workflows remain the supported route.

Validation NOT_RUN, acceptance NOT_CLAIMED; browser OBJ evidence and remaining B3 runtime/readback gates remain pending.
2026-10-24 B3 OBJ browser-equivalent correction: direct WM_OT_obj_import/WM_OT_obj_export calls remain blocked by Blender's WM_operator_winactive, but the catalog now registers them as BROWSER_EQUIVALENT OPEN/SAVE routes so F3 invokes the existing browser-owned file workflows. Catalog hash 2504fd10de825281799ef8959beafbda28bdaccc2d056076fc38fe1cb9833138; report/manifest tests/golden/WBV2-P1424-001/b3-io-operator-browser-equivalent-20261024.md and b3-io-operator-browser-equivalent-20261024-manifest.json; it supersedes the prior UNAVAILABLE classification. Validation NOT_RUN, acceptance NOT_CLAIMED; browser OBJ and remaining B3 runtime/readback gates remain pending.
2026-10-24 B3 OBJ browser action binding: F3 WM_OT_obj_import now invokes the existing file picker/native import path, while WM_OT_obj_export invokes a dedicated file.export-obj command that opens the Native Export dialog with OBJ selected; generic .blend save is no longer used for OBJ export.

2026-10-24 B3 schema cancel cleanup: server-operator-job-server.mjs now propagates HTTP request aborted to the bounded describe child and preserves normal workspace cleanup, so cancelling a first-use F3 schema request cannot leave the provider process running to timeout.

2026-10-24 B3 submit disconnect cleanup: server-operator-job-server.mjs now listens for submit request aborted; if the client disconnects before receiving 202, the provider publishes terminal CANCELLED, kills the bounded process tree and retains no late result.

Incremental web_engine build and r2 frontend/Worker packaging exited 0. First package attempt failed on a pre-existing extra parenthesis in the Server Operator property gate; fixed and retained its failure log.

2026-10-25 B3 OBJ companion import: local File/F3 and single-OBJ selection share a bounded folder/file panel, preserve relative OBJ/MTL/texture paths, persist/remount resources under project ownership, and hand confirmation/cancellation to native wm.obj_import. Web-owned model images are packed via BKE_image_packfiles. Added a three-file deterministic textured fixture. Incremental native build and candidate packaging exited 0: build_web_main_desktop/b3-obj-bundle-import-20261025/candidate.json, SHA-256 ee1cf5e073316b34696caf5d7c1e3f05aab36368c325cfecdab768ccbedd3765.

2026-10-25 B3 Save Copy ownership: corrected the Web menu/dialog previously bound to Save As. Copy-only serialization uses the existing native writer, frame pause, SAVE lock and download while bypassing project metadata commit; original project/name, committed hash/revision and dirty state remain current. Autosave is rearmed after copy completion/failure. App source SHA-256 908e6f34afd903b5b99c1f307cafa65657701d01a749e1e56196b753f13bf5d5.

2026-10-25 B3 F3 Save As: exact WM_OT_save_as_mainfile dispatch now opens the existing filename dialog via file.save-as instead of immediately running generic saveBlend; added the searchable Save As command. Opening/cancelling stays before the save transaction, while confirmation uses the existing new-project/download path. App source SHA-256 2e8a8d1817f67d21d6365f4457c7a03084b288e11d4059f5a3b0eb9036876f21.

2026-10-25 B3 native save readback: WM/gpuFrame now forwards optional Save As copy flag and completion revision through Worker/client/Canvas. Non-copy delivery commits actual downloaded bytes via the existing project transaction under SAVE lock, frame pause and owner/revision guards; copies/legacy receipts only download, and newer edits are not marked saved on conflict. Canvas delivery remains asynchronous for scheduler progress. Native build and candidate packaging exited 0: build_web_main_desktop/b3-native-save-readback-20261025/candidate.json, SHA-256 e0966e036d6d46a4a9faf7fd7192ed96ccde3aa60c58df908624609cf28fdf38.

2026-10-25 B3 native Ctrl+S delivery: the successful native writer now publishes Save/Save As/Copy receipts outside the file selector; selector-owned .blend notification removed to prevent duplicates. Explicit save_as travels through GPU/Worker/client/Canvas so ordinary Save commits exact delivered bytes/name to the current browser project, while Save As creates a project and Copy only downloads. Same-project persistence skips resource self-copy. Native build and candidate packaging exited 0: build_web_main_desktop/b3-native-save-delivery-20261025/candidate.json, SHA-256 af58ff8dac17e7fbf949249e74dfd3621651de91a14c2da7eb1a1b10d00cac7c.

2026-10-25 B3 native file recovery: failed deliveries retain original client/project/revision, stable Save As destination, cached bytes and download-request phase. Retry preserves existing guards and serializes each receipt; project-sync retries skip prior requested downloads. Added independent Retry/download-cached-file-only/Dismiss controls and URL cleanup on failure; Canvas avoids duplicate retained-error notices. Frontend candidate generated from unchanged native artifacts: build_web_main_desktop/b3-native-file-retry-20261025/candidate.json, SHA-256 b06a0e4d7b0b0d2406b4cb0f643e2a0fa10f127318832091465ab9d56499087f.

2026-10-25 B3 recent-project confirmation: recent menu/select now use committed-only open, distinct from explicit autosave restore and Worker restart. User routes reuse Save/Discard/Cancel before reset/replacement, allow approved draft discard only at successful replacement, read target data/resources before Python reset, check owner identity, and rearm autosave on exit. Restart keeps its recovery path.

2026-10-25 B3 native drop cancellation: existing .blend drop popup/Open INVOKE_DEFAULT unsaved confirmation confirmed in source and retained. Canvas staging now supplies AbortSignal to the existing byte reader, offers button/Escape cancellation, aborts on ownership/surface/lifecycle loss, and closes its cancel boundary before native type-9 dispatch. Partial files remain isolated and retained. Frontend candidate generated from unchanged WASM: build_web_main_desktop/b3-native-drop-cancel-20261025/candidate.json, SHA-256 8a03bf8639f7a97411f6011e748e0423e57fea4be6c008f182507863892116c5.

2026-10-25 B3 panel transfer cancellation: each DesktopFileTransfer task now owns AbortController; file/folder uploads and saved-folder restore forward its signal into the existing cancellable reader. Cancel/unmount/session changes abort reads; cancellation reports retained completed-file details as status, actual errors remain errors, and busy ownership is released only after settlement. Dispatched uploads may complete and are not rolled back. Frontend candidate generated from unchanged WASM: build_web_main_desktop/b3-panel-transfer-cancel-20261025/candidate.json, SHA-256 f69652b00bf51bcb463899e3af5a32ec9cf410a8cbc90158df1e123b083cbb77.

2026-10-29 B6 三段式落盘与段2修复：段1 600s production 失败归属为测试预算耗尽（最后点击 595.0s、上限 600000ms、trace 显示分发等待在超时内开始），非独立功能缺陷，unverified；段2 原生 Outliner 展开「返回 ok 但 aria-expanded 不变」定为 missing 并已修复（web_engine_main_state.cpp:4121-4126，展开前后用 TSELEM_OPEN 比较，状态未变时置 changed=false 并返回 "Outliner row has no expandable children"，前端经既有 commandChanged===false 分支显示原因），before sha256 658cd11e… after c7c574bb…，新增 5 行删除 0 行，NOT_RUN；段3 相机后工作区切换在 minimal 已通过、production 未推进到该段，unverified，未改动代码。记录 tests/golden/WBV2-P1424-001/b6-composite-three-segment-20261029.json sha256 e335c27087d718a74c79ae72283efa78749eb3d4c02427c59bbfed658476869f；未编译、未运行、acceptance NOT_CLAIMED。下一动作：增量编译 web_engine 后在 900s 计划下采集 production 单案例。
2026-10-29 B3 ExternalImage 自动保存黑图：定位为 WASM 侧 PNG 编码在 libpng tEXt: invalid keyword 处中止（OIIO 把每条字符串 ImageSpec 属性写成文本块，键名净化后无可保留字节即 png_error），导致无 IDAT、memory save for pack error、自动保存不含像素、恢复回落磁盘黑图；桌面控制组同一资产 exit=0 通过。已按 libpng 自身的可保留字节规则（33-126 或 >=161）在 imb_create_write_spec 增加 PNG-only 守卫，丢弃不可用键名而不是丢掉整幅图像（openimageio_support.cc:499-510，before 6cf1ff47… after ffbbe5ad…，+12/-0）。增量构建 exit=0、0 error、补丁文件 0 warning，产物 web_engine.wasm f856f4c6…；候选 build_web_main_desktop/b3-png-keyword-guard-20261029 candidate.json 7a8c0ce8…。功能测试 NOT_RUN、acceptance NOT_CLAIMED，单案例采集已发起但结果不构成通过。
2026-10-30 B3 ExternalImage 黑图更正：上一批的 PNG 键名守卫（openimageio_support.cc:499-510）无效并已回退到基线 6cf1ff47…；该守卫随行的 wasm f856f4c6… 实际已上产物，错误依旧，证明假设错误。重新取证后定位为两条打包路径的差别：image_memorypack_imbuf（普通打包，image.cc:1486-1491）无重试，而上一批只给 image_memorypack_imbuf_for_autosave 加了重试；G_FILE_AUTOPACK 下 save_as_mainfile 走 wm_files.cc:2249 → BKE_packedfile_pack_all → BKE_image_pack → BKE_image_memorypack → 普通路径，因此打包失败、自动保存不含像素、恢复回落黑图。本批给普通路径补同样的元数据摘除重试（image.cc:1486-1497，before 79b1bb1d… after fe2e3632…，+9/-0），两条路径日志文本仍相同。功能测试 NOT_RUN、acceptance NOT_CLAIMED。
2026-10-30 B3 会话退出/自动保存主案例转 PASS（Chromium，候选 build_web_main_desktop/b3-resunit-v6-20261030，wasm afc18ee7…，用例 tests/e2e/upstream-blendfile-autosave.spec.ts 第 1 条，10.98s）。根因链：源资产自带非法 tEXt 关键字 → 首次 PNG 编码中止；上一批的元数据摘除重试本可救回，但 imb_create_write_spec 对 PNG 还无条件写入字符串属性 ResolutionUnit，摘除元数据后第二次编码仍被 libpng 拒绝（v5 日志 meta=0 text=[\u000f] 证实）。修复：PNG 不再写该字符串属性（openimageio_support.cc:516-531，+4/−1，after bc3064f1…），X/YResolution 数值仍保留。v6 日志只剩 meta=1 text=[…] 一次失败 + autosave pack: retry without metadata 一次重试，memory save for pack error 与 retry failed 全部消失。同一用例另两条子测试仍失败（?ui=web 等 OPEN=SUCCEEDED 超时；spec:90 误用 queryNativeJSON 的 changed===false 断言，已改为 nativeRequest+pythonReply），两处与图像打包无关。validation 记 PASS（单条源案例）、acceptance 仍 NOT_CLAIMED。

2026-11-01 作者态案例改走真实入口并修正证据漂移

metaball / sculpt / fcurve 三个案例由自建 WebEngineClient 改为驱动应用自身 __nativeWorkflowEngine，并以 blend-file-input 真实加载、保存项目 下载后重开；三例 Chromium 均通过，acceptance=NOT_CLAIMED，回执存于 tests/golden/WBV2-P1424-001/artifacts/authoring-green-20261101-rerun/。
期间发现并修复两处自有缺陷造成的偏差：直接对应用 worker 发 openBlend 会与 App 启动时的自身打开竞争，导致快照在无 snapshot 调用时也被替换；setFrame 在桌面属非历史命令，fcurve 案例的可撤销编辑改用 deleteObjectKeyframe。
证据哈希修复：三份已绑定 production receipt 曾被重跑覆盖成 DRIFT，现按归档副本恢复为绑定值（288892aa…/5c2e3933…/e471df93…），并把 P1137/P1142 manifest 内的引用同步到现文件。
B3 spec:133 缺口经 b3-cleanfix3-20261101-run 证据确认已闭合：quit.blend 缺失与损坏时 NATIVE_INVOKE_FAILED 均带原生报告文本。剩余为聚合验收与冻结候选，仍未 CLAIMED。

2026-11-01 浏览器会话内 Python 编辑后撤销被守卫误拒

案例：fx_comp.blend（tests/files/sequence_editing/effects）执行一次 Python 后按 applyCommand {type:'undo'}，桌面可正常撤销，Web 返回 BLEND_READ_FAILED: PYTHON_RESET_MAIN_CHANGED。

源码定位：web_engine_api.cpp:1128-1200 的 reset_python_before_main_replacement 在重置前后各写一次 Main 并逐字节比对；web_engine_main_state.cpp:3708 的 web_engine_blend_main_context_refresh 在首次路径上通过 WM_msgbus_create 补建消息总线并绑定编辑器区域，属一次性运行期初始化。

证据：同一会话内第一次 pythonReset 必改字节（changed:true），第二次 changed:false；不跑 Python 时连续重置字节完全稳定；jsonCommand undo 成功而 applyCommand undo 失败，差异在于后者经 restore_history_entry 走守卫。

改动：web_engine_api.cpp 中守卫在首轮比较判定为变更后再做一次重置与写出，以相邻两次重置的差异作为最终判定。

复测（NOT_CLAIMED）：exec -> applyCommand undo 成功，redo 回到编辑态；handler 析构在重置期间真实改写场景名时守卫仍拒绝替换，场景名保持 CleanupHandlerScene。

2026-11-01 桌面案例补缺与候选验收

修复旧版文件迁移被 Web 跳过，以及原生文件读入后路径缓存覆盖真实路径；已增量构建并规范同步。
候选 build_web_main_desktop/versioning-filepath-20261101：四个原始资产工作流、两个真实后端操作工作流、两个自动保存项及一个退出恢复项通过；原生自动保存选择器重启后案例失败。独立 release 入口检查通过。
阻塞：恢复文件行双击后读回遇到 NATIVE_GESTURE_ACTIVE（gizmo=1）；继续定位 upstream-blendfile-autosave.spec.ts:217-228 与 web_engine_gpu_ui.cpp:394 的事件队列/Main 切换边界，不放宽守卫。其他模块、backend quit、异常掉电与全局发布门禁仍保留。
结论 BLOCKED / NOT_CLAIMED，未生产发布、未推进任务指针、源码覆盖增量不计；完整结果和未采集 inventory 字段见 tests/golden/WBV2-P1424-001/desktop-case-release-assessment-20261101.json，断点见最新 continuation。

2026-11-02 后端原生退出恢复补缺

保留会话槽工作区及 quit.blend，独占 owner 并隔离 peer 工作区；修复重复键时间戳、只读 Main 观察和 checkpoint 持久化期间的按钮状态。
Chromium 正式候选真实改名、取消退出、退出保留、同槽重连与 Recover Last Session 通过；同槽并发拒绝、旧 token、peer、普通文件与 checkpoint 不变均有证据。回执：goal-backend-workspace-reconnect-20261102/B3/source/attempt-kgYm5A/receipt.json。
当前候选 goal-backend-checkpoint-20261101；后端通过不替代 WASM、外部资源、异常终止、存储及全局门禁。整体 active / NOT_CLAIMED，源码 inventory 本批未采集、不计覆盖增量；继续见 continuation-20261102-goal-backend-workspace.json。

2026-11-02 后端六案例连续回归

正式候选 goal-backend-checkpoint-20261101 的 Chromium 后端六案例全部通过：exit 0、6 passed、0 skipped/unexpected/flaky；回执 goal-backend-six-case-live-scan-20261102/B3/source/attempt-YBq0LV/receipt.json。
验证原始文件打开导出、普通/带图片退出恢复、撤销重做、取消、检查点重开、真实 SIGKILL 后自动保存恢复、自动保存驱逐回退、真实保存失败保留与重试，以及原生 peer 工作区不可见。
修复可移植副本改变图片打包状态、键盘逻辑字符、恢复目录覆盖，以及预算扫描撞上截图原子重命名导致的误关闭。错误、预算和危险操作守卫均保留。

2026-11-02 原始 PackedImage WASM 补缺断点

后端六案例通过保持有效，但不替代 WASM 验收。原始 autosave_image_test.blend 的嵌入图像已绑定桌面对照：4×4、260 字节、SHA 一致性及保存重开断言。
已实施 RGBA8 存储适配、sRGBA/UNORM 原字节复制、mipmap 分支/同步兼容、UV 参数类型、图片坐标声明及 ImagePrepass 全局 UBO 绑定；未隐藏覆盖层、未清空数据、未延长截止时间。
最新候选 goal-packed-image-gpu-phase-20261102，WASM 7145ac11…；最新失败 goal-packed-image-gpu-phase-20261102/B3/source/attempt-mZ5ljA/receipt.json 定位到 GPU readback mapping，尚未获得该工作流通过。
完整断点/下一动作见 continuation-20261102-goal-packed-image.json；目标 active / in_progress / NOT_CLAIMED，未生产部署、未推进队列、未新增源码覆盖声明。

2026-11-02 GPU 读回阻塞定位续接

已确认请求串行且实际工作量很小：visibility 单工作组，五个缓冲区合计 42,016 字节；超时发生于提交后的 mapAsync，未改变截止时间。
显式 glFlush 实验无改善，已撤回并完成增量构建与规范同步；当前本机构件 WASM 9df8b019…，下一验证须冻结新的候选并绑定身份。
Chromium 需要强制关闭，但未捕获 device-lost 日志；空进程采样不足以证明 GPU 闲置。下一步按精确交接捕获实际进程树或原始计算请求，禁止盲重跑。
目标 active / in_progress / NOT_CLAIMED，原始图片工作流仍失败，后端六案例通过不外推为整体验收；未部署、未推进队列。
2026-11-02 模块级实测（Chromium，候选绑定）：冻结候选 build_web_main_desktop/versioning-filepath-20261101（candidate.json 6ba7b22c…、wasm d6c90802…）与当前工作树重打包候选 build_web_main_desktop/modules-candidate-20261102（candidate.json 0bbdce9a…、wasm 9df8b019…、App-Hkpp0JpV 6f3d552f…）分别按 7 个模块跑候选可跑 spec，结果写入 tests/golden/WBV2-P1424-001/candidate-modules-20261101/manifest.json。通过：材质/属性 2/2、sequencer 1/1、device-loss（?ui=web）。失败但定性为测试口径：worker-crash 期望对象名 Cube（fixture 为 BasicCube）、smoke.spec.ts 与 215 个 spec 依赖 /src/* 无法对静态候选执行。真实或待定缺口：recent-project modalActive false（dev 同样失败）、blender-app 导入路由仅 OBJ（2026-10-24 既定守卫）、对象编辑 selected 断言、viewport 入口敏感。关键发现：main.tsx（未提交，HEAD 为 <App />）把 / 渲染为 localOnly=true 桌面态，?ui=web 才是 Web 工具界面；71 个候选可跑 spec 中 26 个仍走 /。原生 setDriverExpression 经产品入口实测 ok:true 且 frame*2 在帧 1 得 [2,0,0]，动画缺口在 UI 侧命令未发出而非内核。门禁：部署 HTTP/缓存/契约/发布包/性能通过；check-chromium-release-freeze 绑定 2026-08-19 归档报告（single/js 25aa5136… vs 实物 79647f65…），engine-manifest.json 已按实物重生成；check-rc-release-recovery 断言字面量 anchor.download = "blender-web.blend"，源码已改为 downloadName（回退同名）。validation PARTIAL / acceptance NOT_CLAIMED；未执行部署。
2026-11-02 入口口径复核：web/app/src/main.tsx（未提交；HEAD 为 <App />）把 / 渲染成 <App localOnly={ui!=='web'}/>，即根入口是桌面原生工作面、?ui=web 才是 Web 工具界面。以此口径重跑同一批 spec（未改断言）：action-marker、device-loss、worker-crash 转 PASS（worker-crash 同时把对象名 Cube 修正为 fixture 实际名 BasicCube，属测试缺陷修正）；viewport 3/8 通过；b5-animation 仍失败于 waitNativeModal 空；recent-project 三条超时于等待 桌面 按钮（该按钮只在根入口渲染，属入口依赖）。对象编辑 selected 断言经桌面验证为过期：桌面 collection.hide_viewport=True 后 select_get() 为 False，恢复可见后仍为 False。结论：入口口径可解释本轮大部分失败，剩余真实项为 b5 waitNativeModal、recent-project 的 modalActive 与入口耦合、以及 App.tsx 导入路由仅 OBJ（2026-10-24 既定守卫，但 WASM 内 import_scene.gltf/stl/ply 均可用，属可选扩展缺口）。acceptance 仍 NOT_CLAIMED。
2026-11-02 模块补跑收口：在 ?ui=web（Web 工具入口）下补跑导入导出、序列与上游 blendfile_io：io-format-ui-gate 仍因 accept 仅 .blend,.obj（2026-10-24 OBJ 守卫）失败，两个入口一致；sequencer 改走 ?ui=web 后失败于等待 native-web-tools-toggle（该控件只在根入口渲染）；upstream-blendfile-io 超时于等待 Python 输入 标签。材质/属性模块在当前工作树候选 modules-candidate-20261102（wasm 9df8b019…）上 2/2 通过，与冻结候选一致。?ui=web 下未观察到 gpuUI 帧（__nativeWorkflowGPU 为空），因此 waitNativeModal 类断言在该入口不适用。阶段性结论：模块可跑项已全部实测，失败分为三类——入口口径（26 条根入口 spec、sequencer、recent-project）、既定守卫（导入仅 OBJ）、测试与夹具口径（worker-crash 对象名已修正、viewport 修订号断言、/src/ 依赖 spec 不可对静态候选执行）。真实待决项：/ 与 ?ui=web 哪一个是产品入口（需产品决策）、App.tsx 导入路由是否放开 glTF/GLB/STL/PLY（WASM 内 import_scene 均已可用）。acceptance 仍 NOT_CLAIMED，未执行部署。
2026-11-02 dev 服务器对照：对依赖 /src/* 的 spec 改在 Vite dev 服务器执行，作为静态候选不可用的补偿证据。save-interruption（M7-05 存储中断后 revision/hash/bytes 还原）通过；storage-budget、io-format-ui-gate（OBJ 守卫）、recent-project（modalActive）在 dev 上同样失败，说明这些不是候选漂移而是源码现状；object-editor 在 dev 上失败于保存步骤（候选上失败于工作台点击），差异来自入口口径而非候选质量。结论与残余登记在 tests/golden/WBV2-P1424-001/candidate-modules-20261101/manifest.json 的 devServerCrossChecks。
2026-11-02 恢复与守卫复验：upstream-blendfile-autosave.spec.ts 三条在冻结候选上全部通过（2.2m），此前记录的 NATIVE_GESTURE_ACTIVE 失败绑定于旧 revision（当时 spec sha 7ddcb5d4…，现 e549f175…，文件为未提交状态且 2026-11-01 20:25 修改），不可与本次直接比较；native-active-gesture-guard.spec.ts 同候选通过，真实拖拽进行中危险操作仍被拒绝，Main 与 history 不变，说明守卫未被绕过。入口口径补充：main.tsx 只在 ui==='desktop' 时渲染 DesktopWorkspace，其余（含 / 与 /?ui=native）都是 localOnly 的桌面原生工作面，?ui=web 才是 Web 工具界面；实测两个原生入口 DOM 一致。
2026-11-02 后端会话归属模块 PASS：backend-session-ownership.spec.ts 在冻结候选上 6/6 通过（2.0m），覆盖跨会话资产归属隔离、原生退出恢复未保存 Main、外部图像资源恢复、异常进程丢失只回退到最后自动保存、被驱逐的自动保存仅保留浏览器检查点回退、检查点写入失败保留 Main 并重试恢复。前置条件如实记录：WEB_BLENDER_PROFILE_ROOT 必须位于 tests/golden/ 之下（spec 内断言），BLENDER_BIN 指向 build_blender_native/bin/blender；首次运行失败即因我把 profile root 放在 web/ 下，属测试前置错误而非产品缺陷。同模块的 recent-project-native-production 仍为 1 通过 / 2 失败（modalActive 期望 true 实得 false），dev 服务器同样失败。
2026-11-02 门禁与发布入口收口：通过的门禁为 deployment-http、deployment-cache、deployment-contract、deployment-runbook、release-package（57 文件 / 509816409 字节）、release-performance（默认预算：100k=62239ms，1M=407ms）、release-evidence（17 条记录 0 缺失）、malicious-archive-fixtures、rc-known-limitations、rc-release-notes、io-format-receipt-freshness（14 条回执，伪造/过期/跨版本均拒绝）。失败的四项均为验证产物过期或与契约漂移，不是产品行为缺陷：check-rc-manifest（清单提交 122142c2… 与 HEAD a081c68c… 不符）、check-chromium-release-freeze（绑定 2026-08-19 的 M14-01A 报告 single/js 25aa5136…，实物 79647f65…）、check-rc-release-recovery（断言字面量 anchor.download = "blender-web.blend"，工作树改为 downloadName，回退值同名、HEAD 仍是字面量）、check-csp-resource-policy（工作树契约给 img-src/media-src 加了 blob:，产品确有 <img src=blob:>、CSS cursor:url(blob:) 与序列媒体用途，检查器早于该契约变更）。发布入口在冻结候选上 7 条中 4 条通过（upstream-blendfile-versioning 四条原始资产打开全过），3 条 cross-browser 失败中 1 条是 / 桌面浮层拦截 添加立方体（切换 Web 工具后同一点击成功，已实证），2 条依赖 /src/storage/StorageClient.ts 只能由 dev 服务器提供。acceptance 仍 NOT_CLAIMED，未部署。
2026-11-02 缺陷定性收尾：/ 渲染桌面原生面（带 WebGPU 参数时原生画布 data-native-input-ready=true，属性区为空），Web 工具界面只在 ?ui=web；native-web-tools-toggle 能在 / 放出 Outliner 并让工具栏可点，但属性 workbench 不会出现，属既有入口设计而非新缺陷。据此定性：真实缺陷三项——recent-project 变换后 modalActive 恒为 false（dev 与 ?ui=native 同样失败）、?offscreen=1 下 data-renderer-pixels 始终缺失（24 秒 12 次采样全空，worker frame 消息本身带 visiblePixels）、导入选择器仅 OBJ（既定守卫，import_scene.gltf/glb/stl/ply 在 WASM 内可用，属可选扩展）。测试口径问题——object-editor 第 201 行期望集合隐藏后仍 selected:true（桌面实测隐藏会清除选择且不恢复）、b5 的 read() 在 changed=false 后仍等新帧（空闲画布不再出帧）、26 条 spec 仍以 / 为入口。已实施的测试修正仅 worker-crash 对象名 Cube→BasicCube。候选结论：BLOCKED / acceptance NOT_CLAIMED，未部署。
2026-11-02 失败收窄：native-active-gesture-guard 以 focusNativeViewport → 'g' → waitNativeModal(true) 的相同路径在冻结候选通过，说明原生模态链路正常。因此 b5 的失败点在于 exposeWebTools 之后画布转入非活跃、绘制循环空闲、不再产生新的 gpuUI 帧，waitNativeModal(false, afterId) 自然超时（测试口径）；recent-project 的 modalActive 失败发生在其自身的项目替换/重启流程内（dev 与 ?ui=native 同样复现，保留为真实待查项）；offscreen 的 visiblePixels 在 render() 内采样，只在场景/相机变化时重绘，属性值反映最后一次空闲帧而非渲染损坏。候选仍 BLOCKED，acceptance NOT_CLAIMED，未部署。
2026-11-02 机制定案：native-web-tools-toggle 的 onClick 直接 setGPUSurfaceOpen(false)，原生浮层随即 pointer-events:none、z-index:-1，此后不再产生新的 gpuUI 帧。b5 正是在 exposeWebTools 之后等新帧，必然超时（测试口径）；native-active-gesture-guard 无此切换，故同一模态链在该候选上通过。recent-project 的失败等待位于 transformNative 内部、早于 exposeWebTools（spec 第 24 行），不受该机制影响，modalActive false 对 true 仍保留为真实待查项。另记：脱离 observeNative 夹具的独立探针无法复现 focusNativeViewport 的 VIEW_3D 区域聚焦路径，其按键投递结果不作为推翻夹具证据使用。
2026-11-02 modalActive 根因确认：对照组 modeling-native-modal-production.spec.ts 在冻结候选与 Vite dev 服务器上以同样方式失败（期望 active:true 实得 false），说明 gpuUI 调用后 modalActive 从不置真，属既有原生与 UI 之间的模态状态缺口，不是候选漂移，也与 Web 工具切换无关。受影响范围：recent-project-native-production 两条、b5 的 read()（叠加切换关闭画布）、以及任何 waitNativeModal(page, true)；native-active-gesture-guard 通过是因为它断言守卫拒绝变更而非模态置真。未完项与证据见 tests/golden/WBV2-P1424-001/candidate-modules-20261101/manifest.json，候选 BLOCKED / acceptance NOT_CLAIMED，未部署。

2026-11-03 本地执行恢复与原始案例补缺

当前任务与 parent nextTask 仍为 WBV2-P1424-001；完整目标继续，未推进队列、未部署、未宣称全产品通过。
原生自动保存重启恢复已在 modules-candidate-20261102 实跑 PASS，并在新 71bb0079 候选复测 PASS（goal-autosave-load-20261103/B3/source/attempt-14NgjH）；旧 gizmo 阻塞记录不可直接套用当前构件。
真实 G 键失败的 trace 证明 helper 在 input-ready=false 时先移动指针，导致没有原生鼠标事件；已把原有就绪断言前移，完整拖拽/危险操作拒绝/Escape/历史断言未放宽，纠正此前模态从不置真的笼统结论。
补齐加载后原生依赖图求值（在 staged filepath 建立后调用 BKE_scene_view_layer_graph_evaluated_ensure）：71bb0079 的完整建模、保存重开世界坐标、撤销重做与损坏文件保留均 PASS；桌面对照及回执见 continuation-20261103-goal-resume.json。
a1524c4a / App-C0CdXFIz 新候选接通 STL 产品文件入口与现有 STL_import；原始 empty.blend + all_quads.stl 的桌面几何、真实视图、撤销重做、截断输入数据/历史保留及保存重开 PASS（goal-stl-route-after-20261103/B3/source/attempt-AF8i54）。
打包图像仍在 draw_visibility_compute 的 GPU 读回超时（goal-packed-image-load-20261103/B3/source/attempt-T0XfCM）；OBJ 材质包回归正在按 ViewLayer 活动对象修正读回口径后复跑。PLY/GLTF/GLB、其余业务与全局发布门禁全部保留，整体 acceptance=NOT_CLAIMED。
后续：OBJ 材质包在原始空 Main 与已有 all_quads Main 两种变体均 PASS（goal-obj-main-reader-20261103）；读回改用 ViewLayer.objects.active，保留数据/历史/取消/导出断言。
PLY 已接通原生 PLY_import；b2e64510 / JS 39784d76 候选的原始 cube_ascii.ply 与强化 STL 回归均 PASS，含原始 io_report.fmtf 精度的 UV/颜色/法线、撤销重做、失败保留和保存重开。其余范围与 GPU 图像失败继续保留，仍未整体验收。

2026-11-03 当前候选有界结果

当前冻结候选：build_web_main_desktop/goal-native-mesh-export-20261103；WASM e75c6c6188acbb7d18cde4fb6df2b31b9973f315cd61da8c1156e2ddf7e4e87e，JS 39784d76a1ddbec359057586668fc7002fa0683478e5dfbfc3ab2092c879e060。
补齐原生操作搜索弹窗布局、隐藏画布的交互调度，以及 STL/PLY 原生导出准备/完成通知/浏览器交付；非法文件名、取消、桌面重导入对照和 Main/history 保留通过。
当前选定本地 WASM 8 项与后端 6 项通过；含真实拖拽守卫、重启自动保存、原生退出生产/持久化失败与回退、engine/storage Worker 终止恢复、实际源站存储删除与外部备份恢复。模式分开，数量不是整产品完成度。
可复现计划、退出码、哈希及回执：tests/golden/WBV2-P1424-001/goal-current-scoped-assessment-20261103.json。自然驱逐触发、整浏览器/物理掉电不在上述保证内。
图像 GPU 工作流仍未解决；导出覆盖/原生写失败变体、GLTF/GLB、其余已承诺模块及全局发布门禁继续保留。未部署，目标 active / acceptance NOT_CLAIMED；下一步见 continuation-20261103-goal-recovery-boundaries.json。
2026-11-03 导出边界：同一 e75 候选的 STL/PLY 原生覆盖取消/确认、真实只读目标打开失败与恢复权限重试均 PASS；旧文件/Main/history 保留、实际下载/原生哈希/桌面对照一致。路径输入后的焦点处理遵循原始 file_directory_enter_handle 与 UI 文本编辑语义，没有更改超时或放宽断言。
明确保留中途短写/ENOSPC 未验证项，不以 fopen 权限拒绝替代。新增 GLB 产品入口实际复现拒绝：插件源码已嵌入，但 NumPy 缺失且导入操作未注册；Linux NumPy 二进制不能冒充 WASM 依赖。后续见 continuation-20261103-goal-glb-import.json；整体仍 active / NOT_CLAIMED，未部署。
2026-11-03 GLB 原生依赖：按 Blender 指定 NumPy 2.3.4 构建 13 个 CPython 3.13/Emscripten 静态扩展与原始 Python 包；修正主机头文件误选及旧版随机模块静态符号隔离，未改算法。构件身份见 build_web_numpy/build.json。
Chromium 已实际导入 NumPy；GLB 导入随后暴露工程重置后的插件路径缺口，已补原生 refresh_script_paths，正在重建。attempt-PXS6zh 使用 Vite 前端，仅为诊断；下一轮显式验证冻结 app。目标仍 active / NOT_CLAIMED，GPU 图像和其余模块/门禁保留，未部署。
2026-11-03 普通 GLB 静态候选案例 PASS：goal-native-glb-node-fix-20261103（WASM ed97b858…），桌面对照、真实入口、原生 Main、撤销/重做、损坏文件数据/历史保留及保存重开通过；attempt-tMnS3N，退出码 0，无跳过/重试。见 goal-original-glb-assessment-20261103.json。
修复 WITH_WEB UString 临时引用导致 ShaderNodeOutputMaterial 创建损坏字符串；原始 Meshopt/Draco 解码器仅在真实压缩分支加载。压缩依赖、资源/动画变体、GPU 图像和发布门禁仍保留，正按共享 IO 上下文改动复测 STL/PLY。整体 NOT_CLAIMED，未部署。
2026-11-03 glTF 资源/骨骼案例收口：修正导入临时上下文受 Properties 编辑器钉选、插件重复启动注册及无权重分组读取分配空变形层；保留类型替换/手势保护。原始 2 动作、66 F 曲线、骨骼/权重、材质/贴图与桌面一致，撤销重做、失败保留和保存重开通过。
当前 goal-native-gltf-readonly-20261103（WASM 382c70ea…）的 5 个选定 Chromium 静态候选案例通过，均退出 0、无跳过/重试；回执与哈希见 goal-gltf-current-scoped-assessment-20261103.json。整体仍 NOT_CLAIMED；下一真实缺口为原生 GLB 导出交付，压缩/多文件 glTF、动画/材质渲染、GPU 图像及全局门禁继续保留，未部署。
