Bind continuation claims to accepted workspace heads

[zhiiw]

Summary

Bind durable continuation claims to both the immutable RuntimeEvent replay boundary and the exact accepted managed-workspace head.

Primary invariant

A workspace-bound continuation claim is valid only when SQLite can atomically re-derive the same storage-root binding, workspace epoch, accepted version, Git object identity, and RuntimeEvent prefix. The v1 authority cannot consume v2 claims.

Scope

• ContinuationClaimV2 and continuation_source_v3
• schema 15 workspace-bound continuation authority
• strict rebuild/tamper validation
• schema 14 -> 15 populated migration
• real-process claim transaction crash coverage

This remains a stacked Draft. It does not expose a Desktop/CLI product entry.

中文说明

本切片只证明 workspace-bound continuation claim 的持久化权威：SQLite 必须在同一事务中重建并校验 RuntimeEvent 前缀、storage root、workspace epoch/head/version 与 Git 对象身份。v1 authority 无权消费 v2 claim。

包含 schema 15、严格重建/篡改拒绝、schema 14→15 populated migration 与真实子进程 claim 崩溃测试。当前保持 stacked Draft，不开放 Desktop/CLI 产品入口。

Closed as an obsolete extraction/integration slice. The current delivery path is the merged Gitoxide foundation followed by #40 -> #41 -> #42. This PR remains available as design and implementation history.

该 PR 属于旧 extraction/integration 栈，现已失去独立合并价值。当前交付路径是已合并的 Gitoxide 基础，然后依次审查 #40 → #41 → #42。这里继续保留设计、实现与审查历史。
