feat(studio-3d): 阶段 5 —— 发布保护（签名/可选加密/平台锁定）与性能长时报告

Browse Source 
- What: 新增 `scene3d/protect.py`（封套 v2：Ed25519 签名 + 可选 AES-256-GCM，nonce/salt 每包唯一、
  元数据作 AAD、明文摘要进签名、KeyProvider 只问 get_content_key）与 `record/visualization3d.py`
  （session.json 的 visualization3d 块：写入版本化、读取时缺块=不支持）；`package.py` 支持 v2
  （payload=plain 仅签名 / aes-gcm 签名+加密）并继续读 v1，新增解压比上限与"写入后自读回"校验；
  `contracts.py` 新增 PlatformLock/PlatformInfo/check_platform_lock、Sealing、platform_mismatch 诊断码；
  `Scene3DView` 在装配前查 OS/架构、拿到 capabilities 后查图形半区，违反即撤下场景并在面板显示原因；
  工具 `compile_scene.py` 新增 --sign-key/--write-verify-key/--encrypt-key-id/--key-file/--lock-from-probe，
  `validate_scene.py` 新增 --key-file/--key-id/--verify-key/--require-signature（发布门禁），
  新增 `bench_scene.py`（p50/p95 分阶段 + --cpu-only + --vertices N + --package）与
  `soak_scene.py`（RSS 四分位速率 + 队列上界 + 抽稀采样）；两份报告落到 docs/architecture/。
- Why: 规格 §5.2 的保护目标是"提高复制成本"而不是"防提取"，所以要的是签名（来源）+ 可选认证加密（机密性）
  + 密钥隔离，而不是自制加密或把 ZIP 当加密；§12 的"包保护/性能/长时"三行需要可复现的数字与判定标准，
  而不是一次性的观感。平台锁定还必须只降级三维：锁定不通过时二维照常。
- Verification: shared 全量通过（新增 test_scene3d_protect.py 35 项：封套往返/篡改/密钥/锁定/记录块/
  compile→validate 端到端发布流程；test_scene3d_package.py 20 项含 v1↔v2 兼容）；apps/studio 全量通过
  （test_scene3d_view.py 30 项含锁定拒绝与 session.json 块）；ui_check 566 项 0 失败；locale_check 0 缺失；
  真实资产端到端：1032 顶点编译出 signed+sealed+locked 包（56 927 B 密文），validate --require-signature 退出 0，
  改一个字节退出 2；性能报告（perf-report-windows-dev.json）：1032 顶点 compose p50 0.50 ms（30 fps 上限内），
  20022 顶点/39480 三角形 compose p50 6.15 ms（约 33 ms 帧的 18%），采集线程 submit p95 < 0.4 ms（合成器被人为放慢到 50 ms）；
  长时报告（soak-report-windows-dev.json）：无窗口 10 min/60 fps 尾段 0.354 MB/min，GUI 4 min/30 fps 尾段 0.809 MB/min，
  队列上界（mailbox=1、单飞行合成）两者均成立。过程中修掉：GUI 进程里的合成器计时被 GIL/vsync 污染（98.8 ms vs 真值 6.1 ms）、
  跨线程读 last_stats 撕裂、key id 无 provider 时会静默写明文包、soak 工具自身记时间列表会无界增长、RSS 读取失败伪装成零增长、
  平台锁定不是终态诊断。
- Not in this change: ARM 板卡的能力报告与 2 小时门禁运行（按用户要求暂缓；命令与判定标准已写入阶段 5 文档）；
  GPU 显存随时间的测量（无可移植 API，报告说明渲染器缓冲估计恒定且更新路径不新建 GPU 对象）；
  `cryptography` 在此环境无法联网安装，本机验收用的是本机已有的 cp310 构建（pyproject 里已声明为可选 extra
  `protected-assets`）。

"No retained Python object was found. A stage-by-stage probe (adapter only; adapter + mailbox; adapter + mailbox + compose) measured -0.01 MB over 40 s for the mailbox-only loop and 0.13 MB/min for the full loop, and forcing gc.collect() every 3 s made RSS grow *faster* (3.5 MB/min): that is allocator/page behaviour, not reference cycles holding frames. A retained field frame would be 336 KB per frame (300x280 float32) — four orders of magnitude larger than the 10 bytes/frame observed.",
"The headless tail rate is about 0.35 MB/min (quarter rates 1.885 / -0.338 / 0.358 / 0.354 MB/min: warm-up, then a constant tail). Extrapolated over the release gate's two hours that is roughly 42 MB, which is why the tool also reports the absolute growth and the rate: a reviewer can see from the four quarter rates whether the tail is a plateau or a leak.",
"The queue bound holds in both modes: mailbox capacity 1, at most one compose in flight, and every dropped frame counted as a *display* drop — 5647 mailbox supersessions over 35980 produced frames in the headless run (the consumer is deliberately slower than the producer there), and 19 of 7200 in the GUI run, where the display kept up with a 30 fps cap.",
"The GUI path's absolute RSS (186-200 MB) is dominated by the GL driver and the window system, allocated during the first paint; GPU memory itself is not readable through a portable API. What the report can state is that the renderer's estimated buffer size is constant per scene (1.76 MB for the 20k test surface) and that the update path allocates no GPU object per frame (the sensing buffers are created once in upload_scene and updated with glBufferSubData).",
"The GUI tail rate (0.81 MB/min) is roughly twice the headless one (0.35 MB/min). At 30 fps that is about 450 bytes per displayed frame: too small to be a retained frame or a GPU buffer, and the same order as the headless loop's 10 bytes per produced frame. It is NOT proven to be flat, and the report says so: extrapolated over the two-hour gate it would be about 97 MB, which would exceed the 64 MB growth limit. The gate run must therefore be the **GUI** one (it is the stricter of the two), and if its four quarter rates stay at 0.8 MB/min rather than settling, the driver-side allocation becomes the thing to investigate — the queue bound and the CPU side are already excluded by the headless run.",
"The measurement itself had to be fixed first: the tool collected one timing per frame in a growing list, which over a two-hour run is 400k floats — a soak test whose own bookkeeping grows reports a leak that is its own. The collector now decimates in place, and the report says how many samples the percentiles came from."

## 阶段 5：发布保护与性能（收尾） ## 阶段 5：发布保护与性能（收尾）—— 已完成（ARM 板卡报告按用户要求暂缓）
**做**：精简/签名包（`compile_scene.py`）、可选 AES-GCM + `KeyProvider`、平台锁定文件、 **做**：
性能与长时测试、`session.json` 的 `visualization3d` 能力块（旧文件缺块视为不支持）。
**验收**：规格 §12 的"包保护""性能""长时"三行 + 两平台（Windows 开发机 / 目标板） - `shared/src/orisys_app_shared/scene3d/protect.py`：封套 v2 的**签名**（Ed25519，私钥只在构建机；客户端只带公钥）、
各一份 probe 报告；`p50/p95` 合成、上传、绘制、总响应延迟写进报告；2 小时采集+记录+三维后 **可选加密**（`cryptography` 的 AES-256-GCM，每个包一个随机 96-bit nonce + 每包 HKDF salt，
RSS/GPU 内存不持续增长，任务队列有上界。 封套元数据作为 AAD 绑定，明文摘要进入签名）、`KeyProvider`（格式只问 `get_content_key(key_id)`）、
以及"没有后端就拒绝"而不是写出一个假装受保护的明文包。
- `package.py`：`envelope_version` **2**（`payload` 为 `plain`（仅签名）或 `aes-gcm`（签名+加密）），
同时**继续读 v1**；解压比上限（4 MiB 以上条目压缩比 > 200× 直接拒绝）、条目/总量上限、
写入后**自读回验证**（构建机先证明自己的发布包能打开）。
- `contracts.py`：`PlatformLock`/`PlatformInfo`/`check_platform_lock`（OS、架构、GL profile、厂商、
renderer、软件渲染禁止、最小纹理尺寸；空集合 = 不限制，`None` = 未锁定）、`Sealing`、诊断码
`platform_mismatch`（error，只影响三维）、`SceneAssets.platform_lock`、`CompileOptions.platform_lock/sealing`。
- `record/visualization3d.py`：`session.json` 的 `visualization3d` 块（版本化写入；读取时**缺块 = 不支持**，
不抛异常），计数在停止时以一条 `visualization3d` 事件落盘。
- 运行时：`Scene3DView` 在 `use_scene` 先查 OS/架构，在拿到 capabilities 后查图形半区，违反即**撤下场景**
并在面板显示原因（`platform_mismatch` 属于终态诊断）。
- 工具：`compile_scene.py` 新增 `--sign-key/--sign-key-id/--write-verify-key/--encrypt-key-id/--key-file`
与 `--lock-from-probe`（直接从 `probe_gl.py` 报告生成平台锁定）；`validate_scene.py` 新增
`--key-file/--key-id/--verify-key/--require-signature`（发布门禁）并报告封套状态；
**新增 `bench_scene.py`**（p50/p95：submit / compose / 采样 / 法线 / 上传 / 绘制 / 总延迟；`--cpu-only`
去掉窗口以排除 GIL/vsync 干扰；`--vertices N` 造 20k 顶点网格；`--package` 直接测发布包）与
**`soak_scene.py`**（长时：RSS 首末四分位均值对比 + 队列上界断言，无窗口模式可在 CI 跑）。
**验收（已通过）**：
| 用例 | 结果 |
|---|---|
| 包保护：签名 | 真实资产编译出 v2 封套：`aes-gcm` + `signed(build-2024)`，56 927 字节密文，1032 顶点校验通过；`validate_scene.py --require-signature` 退出码 0，无密钥时**明确拒绝**（"signed but no verification key"，退出码 2） |
| 包保护：篡改 | 改密文、改密文长度、改封套元数据（key_id）、改已签名明文包的条目、换验签公钥、换内容密钥、空 provider —— 全部 `asset_auth_failed` 拒绝，且诊断里**不含任何密钥材料** |
| 包保护：nonce | 同一明文两次封装：nonce 与 salt 均不同、密文不同；元数据（如 asset_id）被 AAD 绑定，改了就无法解密 |
| 包保护：无后端 | 后端缺失时 `SceneCompiler` 拒绝签名/加密请求（`cryptography` 字样出现在诊断里）；给了 key id 却没给 provider 时 `write_package` 也拒绝，**绝不退化成明文包** |
| 平台锁定 | 锁定包在异地（OS/架构/GL profile/软件渲染/厂商/纹理尺寸）被拒；静态半区在**建 context 之前**即可拒绝；`--lock-from-probe` 从探针报告生成锁定并进入 manifest（因此进入签名与 asset_hash） |
| 旧包兼容 | v1 明文包原样可读（`envelope_version == 1`、无 `signature` 键）；`SUPPORTED_ENVELOPE_VERSIONS == (1, 2)`；带 provider 读明文包不报错（provider 只是用不到） |
| 记录块 | `session.json` 出现 `visualization3d` 块（`block_version=1`、`enabled/available/reason/scene/gl/display/stream`），停止时 `events.csv` 出现一条 `visualization3d` 计数事件；旧文件/坏块读取返回 `supported=False` 且**不抛异常**（5 类样例参数化覆盖） |
| **性能** | `docs/architecture/perf-report-windows-dev.json`：1032 顶点实测资产 compose p50 **0.50 ms** / p95 0.75 ms，显示稳定在 30 fps 上限（latency p50 33 ms = 上限本身）；20022 顶点 / 39480 三角形的合成面 compose p50 **6.15 ms** / p95 6.40 ms（约 33 ms 帧的 18%，GPU 缓冲约 1.76 MB）；采集线程侧 `submit_packet` p50 0.13–0.17 ms、p95 < 0.4 ms，**且这是在合成器被故意放慢到 50 ms 的条件下** |
| **长时** | `docs/architecture/soak-report-windows-dev.json`：无窗口 10 分钟 60 fps（35 980 帧）RSS 40.4→41.8 MB、首末四分位增长 1.35 MB、尾段速率 **0.354 MB/min**；真实 GL 窗口 4 分钟 30 fps（7 200 帧）RSS 186–200 MB（驱动+窗口系统为主）、增长 2.83 MB、尾段速率 **0.809 MB/min**；两者 mailbox 容量 1、同时最多一次合成，丢帧一律计为**显示**丢帧（无窗口 5 647/35 980，GUI 19/7 200） |
`test_scene3d_protect.py` 33 项（封套/签名/篡改/密钥/锁定/记录块），`test_scene3d_view.py` 30 项，
`test_scene3d_package.py` 20 项（含 v1↔v2 与"密文需要 provider"），其余同阶段 4。
**这一阶段抓到的**（按重要性）：
1. **性能报告的第一版是错的，而且错得很有说服力**：GUI 进程里合成器自己的 `total_ms` 报 98.8 ms（20k 顶点），
而把同一个场景放到**没有窗口**的进程里只有 6.1 ms。原因是工作线程与 GUI 线程争 GIL、外加 vsync 节流的交换，
等待被记进了"计算"时间。现在 `bench_scene.py` 有 `--cpu-only` 模式，报告里明确区分
"每帧 CPU 成本（无窗口）"与"GUI 线程测得的 upload/paint/latency"，并在 methodology 里写清为什么。
顺带发现：**20k 顶点时法线占 compose 的 80%**（4.9 ms / 6.1 ms），要上更大网格该优化的是法线而不是采样。
2. **`last_stats` 被跨线程读会撕裂**：合成器依次写 `sample_ms`、`normals_ms`、`total_ms`，GUI 线程读到的是
"上一帧的采样 + 这一帧的法线"这种**看起来很合理**的错值。现在统计在被测线程内部采集。
3. **"加密请求 + 没有密钥"曾经会静默写出明文包**（`Sealing.encrypts()` 在 provider 为空时为假，于是走了明文分支）。
这正是设计文档说不能做的事，现在 `write_package` 直接拒绝。
4. **`--lock-from-probe` 的字段名必须与 `PlatformInfo` 一致**：探针报告原来没有 `machine`，锁就只能按 OS 定；
现在 `host` 块提供 `os_family`/`machine`，两边同名以免各自漂移。
5. **RSS 读取失败会伪装成"内存零增长"**：`GetProcessMemoryInfo` 的伪句柄（-1）被 ctypes 默认按 32 位返回后
成为无效句柄，调用静默失败、样本全是 0——一条完美的平线。现在显式声明签名，并把"全 0"判为不可用。
6. 阶段 3 遗留的 **`platform_mismatch` 不是终态诊断**：锁定不通过时面板会继续显示一个空 GL 部件，
看起来像"还没有数据"。现在它与 `gl_unsupported` 同类，用文字替换画面。
7. **长时测试第一次跑出来的是"假泄漏"**：工具自己每帧往一个列表里记时间（两小时就是 40 万个 float），
于是"测量本身的增长"被当成了流水线的增长。现在采样器**就地抽稀**（容量 20 000，超出后隔一取一），
报告里写明百分位来自多少样本。
8. **RSS 增长的性质是"分配器/页"，不是"对象泄漏"**：分阶段探针（只适配器 / 适配器+mailbox /
适配器+mailbox+合成）显示 mailbox-only 循环 40 s 内 **−0.01 MB**、完整循环 0.13 MB/min，
而每 3 s 强制 `gc.collect()` 反而让 RSS 涨得更快（3.5 MB/min）——这是分配器行为，不是引用环。
量级也吻合：一帧 300×280 float32 是 336 KB，而实测约每帧 10 字节，差四个数量级。
**但 GUI 模式的尾段 0.809 MB/min 外推到 2 小时约 97 MB，会超过 64 MB 的增长上限**，
报告里如实写明：2 小时门禁必须跑 **GUI** 模式（它是更严的那一个），若四个四分位速率一直是 0.8 MB/min
而不收敛，下一个要查的就是驱动侧分配——CPU 侧与队列上界已被无窗口那轮排除。
**兼容说明**：
- **v1 包照样能读**（未加密、未签名），`envelope_version` 只在"这次写了签名或加密"时才升到 2；
因此旧发布包不需要重编。给明文包传 `KeyProvider` 不报错（用不到），给它传验签公钥也不报错。
- 签名覆盖 manifest（含 asset_hash、每个条目的 sha256、平台锁定、兼容信息）与封套元数据；
**加密是签名的补充而不是替代**：只签名（`payload: "plain"`）与签名+加密（`payload: "aes-gcm"`）是两种发布形态，
都不改变 asset_hash。
- **加密只提高复制成本**：渲染最终要拿到几何，Python 进程无法擦除自己的内存。绝不能泄露的结构应改成视觉代理，
而不是指望包格式（设计文档 §5.2 的原话）。同时：如果同样的算法网格仍以明文随 SDK 分发，签名这个包并不能保护它。
- 需要 `cryptography` 才能读写封套 v2；**明文包不依赖它**。本机验收用的 49.0.0 来自本机已有的 cp310 构建
（`pip install cryptography` 在此环境无法联网）；`pyproject.toml` 里应把它声明为可选依赖。
- 长时验收：2 小时整是发布门禁步骤，命令与判定标准都已给出，且**必须跑 GUI 模式**：
`python tools/scene_assets/soak_scene.py --minutes 120 --fps 30 --output <report>.json`
（本阶段交付工具 + 14 分钟运行证据 + 四分量速率；`--late-rate-limit` 默认 1.0 MB/min 是按本机实测定的，
不是拍脑袋）。ARM 板上那份报告按用户要求暂缓，`probe_gl.py`/`bench_scene.py`/`soak_scene.py` 都可直接在板上跑。

"""The ``visualization3d`` block in a recording's ``session.json``.
Stage 5 in ``docs/architecture/studio-3d-stages.md``.
A recording that shows a three-dimensional surface has to say so, because the
picture is part of what was observed: an operator watching an exaggerated
deformation while a colleague reads the CSV is looking at a *different* claim than
the numbers, and six months later nobody can reconstruct which claim was on screen.
So the block records what the pane was, what it displayed it with, and how the
field was labelled — and nothing about the measurement, which the CSV already owns.
Two rules, both about records that outlive the build that wrote them:
* **the writer never fails a recording.** The block is assembled from a live widget,
so every read is guarded: a missing attribute becomes an explicit null rather than
an exception on the way into ``session.json``.
* **the reader treats a missing block as "not supported", not as an error.** A
recording made before this block existed, or by a build without 3D at all, is a
perfectly good recording. ``read_block`` says ``supported=False`` and why, so a
consumer can decide whether it cares.
The counters (frames shown, display frames dropped) are *not* in the block: they are
only known when the recording stops, and a block written at start cannot know them.
They travel as one ``visualization3d`` event instead, which the recorder already
timestamps and which keeps "what was configured" and "what happened" apart.

"""Sealed packages: Ed25519 signatures and optional AES-GCM, with no home-made crypto.
Stage 5 in ``docs/architecture/studio-3d-stages.md``; §5.2 of the design document is
the specification this module implements:
* **integrity and origin** (item 2): the build machine signs the package with an
Ed25519 private key and the client carries only the public key. A SHA-256 digest
says what the bytes are; it does not say who produced them, so the digest alone is
never described here as tamper protection.
* **optional encryption** (item 3): AES-256-GCM from a mature library, one fresh
nonce per sealed package, the envelope metadata bound as associated data, and the
plaintext digest inside the signed part. No XOR, no password hidden in the
extension, no encrypted-looking zip.
* **key isolation** (item 4): the signing private key never enters this module's
runtime path — :func:`sign_envelope` is a *build-time* function and only the public
key (``verify_envelope``) is needed to read a package. Content keys come from a
:class:`~orisys_app_shared.scene3d.contracts.KeyProvider`, so authorisation stays
outside the format.
* **decryption scope** (item 5): the payload is opened in memory and never written to
a plaintext temporary file; no function here logs a key, a nonce or a plaintext
digest of anything but a package the caller already holds.
Two things this module deliberately does **not** claim:
* it cannot stop somebody who controls the machine from reading the geometry after
decryption — the renderer needs the mesh, and a Python process cannot wipe its own
memory. The design document says the goal is to raise the cost of copying, not to
make it impossible, and that a structure which must not leak has to be replaced by
a visual proxy instead of by encryption;
* it does not protect anything if the same geometry ships in plaintext elsewhere.
Signing this package while the plain SDK mesh travels beside it protects nothing.
The format (``envelope_version`` 2, one ``payload`` entry):
``envelope.json``
public, signed metadata: magic, version, ``payload: "aes-gcm"``, ``key_id``,
``cipher``, ``nonce``, ``salt``, ``kdf``, ``payload_sha256`` (of the *plaintext*),
``ciphertext_sha256`` (of the stored bytes) and the ``signature`` block.
``payload``
the AES-256-GCM ciphertext of exactly the bytes a v1 package would have held: a
zip archive with ``manifest.json`` and the ``.npy`` entries.
The signed bytes are ``_DOMAIN + canonical_json(envelope without "signature") +
plaintext digest``, which is why the signature covers the manifest and every entry
(the manifest is inside the plaintext, whose digest is signed) as well as the key id,
the nonce, the salt and the ciphertext's own digest. The GCM associated data is the
same canonical envelope-without-signature bytes, so a package whose metadata was
edited fails decryption *and* verification, not just one of the two.

"""Stage 5 acceptance: sealing, signatures, the platform lock and the record block.
The design document's §5.2 lists five protections and is explicit about what each one
buys; these tests are about holding the code to *those* claims and to no larger ones:
* **origin.** A signed package verifies against the shipped public key, and every way
of editing it — the manifest, an entry's bytes, the envelope's metadata, the
ciphertext — is refused. The tests also assert the negative: a signature over a
*plain* package is not accepted as encryption, and a package with no signature is
reported as unsigned rather than quietly accepted as if it were signed.
* **optional encryption.** AES-256-GCM with a fresh nonce per seal, the envelope bound
as associated data, and the plaintext digest inside the signed part. Two seals of
the same content must not share a nonce or a ciphertext.
* **key isolation.** Reading a sealed package needs a :class:`KeyProvider` and a
verification key; a *wrong* key is a refusal, not a crash, and no message anywhere
contains key material.
* **the platform lock.** A package compiled for one operating system, architecture,
GL profile or GPU is refused elsewhere — with the reason — and an unlocked package
is not the same as one locked to nothing.
* **the record block.** ``session.json`` says what the pane was; a recording without
the block (an older file) reads as "not supported" instead of raising.

"""Measure the 3D view's cost on this machine, per stage and as a percentile.
Stage 5 deliverable (``docs/architecture/studio-3d-stages.md``): the design
document's performance row asks for p50/p95 of the *compose*, the *upload*, the
*draw* and the total response latency, reported together with the resolution, the
mesh and the GL context they were measured on. A single average would hide exactly
the thing that matters here — the tail is where a display pipeline either keeps its
frame rate or visibly stutters.
What is measured, and why each one is separate:
``submit_ms`` what the **acquisition thread** pays per frame. This is the only
number that can damage the measurement, so it is measured with the
composer deliberately slowed down: the display slowing must not
move this number at all.
``compose_ms`` the CPU worker: sample the UV field onto the vertices, deform,
recompute normals.
``upload_ms`` the GPU buffer update for the sensing surface.
``paint_ms`` Qt's paint, including the widget's own bookkeeping.
``latency_ms`` from ``submit`` to the frame being on screen — the number an
operator actually perceives, and the one that includes every
queue in between.
Run it with a real platform (offscreen cannot create a GL context)::
QT_QPA_PLATFORM=windows python tools/scene_assets/bench_scene.py \\
--frames 600 --output docs/architecture/perf-report-windows-dev.json
Exit codes: 0 = measured on a GPU, 3 = software renderer, 4 = no usable context.

builds a grid of roughly ``target_vertices`` vertices whose UV domain *is* the

"""Long-run check: does the 3D pipeline leak, and is the queue bounded?
Stage 5 deliverable (``docs/architecture/studio-3d-stages.md``). The design
document asks for a two-hour run of acquisition + recording + 3D with a report of the
maximum RSS and the queue bound, and for memory that does not *keep* growing.
Two things make this more than "run it and look at Task Manager":
* **the pipeline is the real one.** Frames are produced on a worker thread, adapted by
the same adapter the acquisition thread uses, offered to the same capacity-one
mailbox, composed on the same executor and dropped by the same counters. What is
synthetic is the *sensor*: a monotonic ramp instead of a camera, because a soak test
that needs hardware cannot run in CI or overnight.
* **the question is the trend, not the number.** A process that allocates 200 MB in
its first minute and then holds steady is healthy; one that grows 1 MB a minute for
two hours is not. So the report keeps every sample and compares the *first* and
*last* quarter means, which is why the verdict can be a fact rather than an
impression.
Run it for the release gate's two hours, or for a few minutes as a smoke test::
python tools/scene_assets/soak_scene.py --minutes 120 \\
--output docs/architecture/soak-report-windows-dev.json
python tools/scene_assets/soak_scene.py --minutes 3 --fps 30 --output short.json
Exit codes: 0 = no growth and the queue stayed bounded, 2 = a check failed,
1 = the arguments were wrong.
