Make the kernel context own an aligned heap and packed runtime arena, including Definition and scheduler regions. Prepare capacity once and freeze it explicitly; launch binding only validates identity and sizes before borrowing existing addresses. Preserve ownership on failed allocation rollback or close for retry, and retain platform allocator accounting. Distinguish dedicated AICPU and hidden AICore stream creation and their completion events. Test capacity boundaries, lifecycle, allocator failures, close retry and concurrent preparation on both HBG architectures. Include the kernel-mode C ABI, state and invocation headers required by this implementation. Retain the preceding HBG resource and packet changes present in this draft where applicable. Public kernel launch integration remains pending. Co-authored-by: sunkaixuan2018 <baiyi@mail.ustc.edu.cn>

关闭：交付路线已替代（superseded）根据维护者确认，关闭这份旧 kernel-mode PR。 **原因：**这份累计的 HBG prepare/freeze 旧栈已被 #2216 的集成线吸收；后续资源与初始化合同又在那里继续演进。当前 main 的执行与发布边界已经不同，不继续将此累计快照作为独立合入单元。 **仍需保留／迁移：**保留资源规划、对齐/容量预检、冻结地址及失败后保有资源的机制和测试；后续接当前共同执行层的 owner、容量与退休合同。 当前确定路线是 Pipeline A → kernel eager → capture/replay：两种资源模式接共同执行与退休层，每次 eager 重新准备并提交一次。集成分支中的采用不等于已合入 main，也不代表本 PR 的全部目标已交付。 本次只关闭旧 PR，保留分支、提交、作者贡献、测试及实验记录，供后续按能力迁移。 本次核查 head： |

Move kernel device capacity ownership into context resource preparation. Allocate one aligned heap and one packed runtime arena, with Definition and scheduler slices, then freeze their addresses and capacities. Launch binding only checks context identity and required sizes before borrowing existing addresses.
Preserve platform allocator accounting and retain ownership after rollback or close failures so cleanup can be retried. Context stream creation distinguishes dedicated non-hidden AICPU from hidden AICore; caller remains a separate borrowed stream.
Validation
mkdocs build --strictpassed separately at all five PR heads. The HBG contract page is included in navigation from H1; the execution-slot page is included from H3.Public K1 owner integration remains pending. Context close requires external quiescence and captured-graph lifetime ordering; these resource helpers do not introduce hidden synchronization.
Dependency and review scope
Draft 3/5: Context prepare/freeze. Depends on #2172.
5e8cbf85.This draft is rebased onto
mainata1aa7fddf42b2d28849bc3fb6fe1eb50ab891324and squashed to one commit. The rebase retains the upstream documentation-theme update. Source and test files match the previous PR head exactly; the squash preserves the complete rebased tree. Applicable pre-commit checks passed again.All five HBG drafts target
main. Each PR has exactly one commit, containing K1 plus all HBG milestones through the stage in its title. Squashing changes commit history, not the cumulative code scope. The original isolated diff above remains available to review this stage alone. Rebase in dependency order after prerequisites land.The K1 snapshot originally carried from
21fb15c0is included in this squashed commit, with its human author retained as co-author. Upstream #2064 remains open and has advanced; alignment with its final version remains public execution integration work.No idle onboard devices were available. Simulation golden checks cover existing program-mode regression; mixed ACLGraph capture/replay, DSV4 CSA device accuracy and comparative performance remain unvalidated.
