Why: I2 switches the direct path to the kernel transcript as the authoritative
context; the backend head carries that switch plus the nested kernel pin.
Evidence: SELF - gitlinks equal the pushed branch heads; combined make test
recorded on the task card after this commit.
Impact: Pointer only.
Why: Backend #115 merged the transcript-authoritative switch; the Dev
combination must test the merged head (with main's concurrent EXT-14).
Evidence: SELF - gitlink equals backend origin/main head.
Impact: Pointer only.
Why: include the current integration baseline before verification.
Evidence: fetched origin/main=6c763cc1cf4b3e980835de0ad864220f97f3c93c.
Impact: integrate upstream changes without rewriting task history.
Refs: task-sync
Why: Squad #49 aligned its nested agent-native pin with the Dev top-level
pointer; the Dev worktree records the merged head.
Evidence: SELF - gitlink equals Agent-Squad main head.
Impact: Pointer only.
Why: Backend #115 (transcript-authoritative switch) and #118 (squad pin
alignment) merged; the Dev combination tests the merged head.
Evidence: SELF - gitlink equals backend origin/main head; make test recorded
on the task card after this commit.
Impact: Pointer only.
Why: Backend #114 (EXT-14, commands-as-tools) added the runmgr -> cmdbus
production import but its Dev-side ratchet update went missing, so make test
fails on any Dev head combining it (backend CI does not run the Dev
architecture check). Recorded here with the merge that surfaces it.
Evidence: SELF - lint-boundaries passes after the entry; the edge exists in
backend main (internal/runmgr/runmgr.go imports cmdbus).
Impact: Ratchet baseline only; unblocks the Dev combination for all in-flight
work.
Why: include the current integration baseline before verification.
Evidence: fetched origin/main=13e03ab15d89d13e0b1cc6848d76776c723a6f96.
Impact: integrate upstream changes without rewriting task history.

摘要
P2 上下文保真 · 增量 I2 的 Dev 组合 PR（P2 收口）。组件均已合入：
Agent-Native #41（思考捕获/回放）、Backend #115（转录为权威上下文）、
Backend #118 + Agent-Squad #49（嵌套指针对齐）。I1 已随 Dev #280 合入。
I2 内容：首轮整段组装一次性播种内核会话转录；后续轮只传当前用户消息，完整
工具结果/参数/附件原文由转录承载；结构分歧（排除/变体/重新生成，指纹判定）
→ 重播种（等价映射，单测覆盖）；动态上下文（尾注/环境/新命中模块）经 Reminders
逐轮刷新；接近窗口触发 9 段压缩；MiniMax 思考随转录持久并回放。
本 PR 另含：架构棘轮补 runmgr→cmdbus 边（Backend #114 遗漏的 Dev 侧更新，
main 此前组合即红；本 PR 修复）。
真实模型三方对照（同 golden 集，plan-followup 3 轮）
pm-tool 检查失败 4→0→0；终稿声称缺章节 0→3→0。读原件归零属设计使然
