跨文件状态任务的稳定路径只有文件级拆解

当前没有模型能替代端到端自治迁移。应拆分：Opus 4.8 做规划和常规批处理，确定性测试套件做验证，疑难点进入人工门禁。

决策栈
使用
tasks can be decomposed to file-level, external test suite exists
claude/opus-4.8使用
simple text/syntax transformations at scale, cost-sensitive
claude/sonnet-4.6拆解
task requires multi-file state coherence across >50K tokens
multi-model人工门禁
output must be directly mergeable patch
human认知转移
模型层| ID | 关系 | 执行体 | 结果 | 输出 |
|---|---|---|---|---|
| CT-D2-001 | locate@cross_file_state | claude/opus-4.8 | 有边界 | 约 5 万 token 后退化；Dynamic Workflows 可提升吞吐 |
| CT-D2-002 | repair@large_repo | claude/opus-4.8 | 有边界 | effective for routine batch repair when decomposed to file-level; 不能替代端到端自治迁移 |
| CT-D2-003 | repair@large_repo | claude/sonnet-4.6 | 拒绝 | 长程多文件任务会失去一致性; use for simple batch transformations only |
| CT-D2-004 | generalize@stop_condition | claude/opus-4.8 | 有边界 | recognizes completion earlier than Fable 5; resource consumption more predictable |
E-D2-001有边界
Stripe reported Fable 5 compressed months of engineering into days on large codebase migration
Anthropic Fable 5 launch, June 2026E-D2-002不确定
Opus 4.8 cross-file state tracking degrades after ~50K tokens
根据相邻证据推断： SWE-Bench Pro results + community reportsE-D2-003有边界
Opus 4.8 Dynamic Workflows feature enables parallel agentic coding
Anthropic Opus 4.8 release, May 2026
