metadata-protocol: admit a package beside the one owner of an App pair row only once the by-name read follows the registry binding (withdrawn row 12 of #32408) #32899

Follow-up of #32408 (PR #32815). Epic ruling 6838245909 (B, chosen by the seat in 6838268615): row 12 is withdrawn from PR #32815, so the doors and the cold seal keep main's answer (refuse the arriving package W and report it). This card carries the admission, gated on the by-name read. Source: epic red-line read 6838271054, "For the epic seat" item 2 and must-fix 2.

维护者速读

• 改什么：App 的 pair 行只能归 X（声明了 X，或 X 是唯一持有者）时，另一个也发同一 locale 的包 W 到来，门和 seal 现在拒绝并报告。本卡在按名读（protocol 的 getMetaItem）跟随注册表绑定之后，再放行 W。
• 为什么：在 W 被放行的状态下，注册表在每种顺序都把这行答给 X、把 W 自己的成员答给 W，但按名读按注册顺序作答：X 的精确地址把行记到先注册的 W 名下；W 停用时 X 的地址和裸读被扣下；两个到来者 W、V 时答案随顺序变（专题红线 2）。
• 风险：放宽一处安装拒绝，必须声明为 widening；按名读的改动在另一个包。
• 先看：packages/metadata-protocol 的按名读路径，以及 fix(objectql)!: every reader of the registry's overlay slot binds a row of an App's customization pair by the exact read's owner rule (ADR-0150 D4) #32815 的 registeredBundleHolding / BundleArrival。
• 验证：按名读的四格（6838271054 第 2 项）在两种注册顺序下都跟随注册表；之后放行 W（declared X，或 X 唯一所有者且 W 在 App 外），两道门和 seal 各钉；反向顺序（W 先、X 后）也放行 X，作为声明的 widening。
• 需要你做的：无，p2，席位落地。

Do

1. Make the by-name read follow the registry binding in this state; pin the four cells in both registration orders.
2. Then admit W at both doors and stop the seal report, for the row that binds to X either way (declared X, or X the one owner with W outside the App), and admit X in the reverse order; declare every move as a widening row with pins in each order.

Clause-②: yes (widening) expected. Metadata-protocol: the dev measures.
