Why

Q3 WP1：core.WorkflowDef 编译为 squad 图执行（P4 上限与 DeniedTools 在编译入口强制），为 WP2 退役 legacy SpawnSubagent 压缩执行器铺路。

What

internal/wfcompile（新包）：
- 编译器：六类步骤映射（prompt→角色步 Brief；hitl/tool/artifact/card/script→宿主 intent 步 wf.；critic→wf.critic 评审步 + evaluator-optimizer Loop，预算=maxRetries+1）；{{input}}/{{slots.}} 编译期渲染；{{steps.X.output}} 哨兵保护——人读字段编译为文件指引、机器字段还原 token 运行期解析
- 宿主 IntentRunner + 合成目录：AskHITL/ExecuteTool/WriteArtifact/CreateCard/codeorch 脚本宿主（限额 50/1MB/600/1800s 同款）/judgeStep 移植（无法解析=不通过 fail-closed；评审预算耗尽=步骤失败）
- RunCompiled 驱动：槽位 HITL 收齐 → 编译 → squad 引擎（compiledPlanner，动态工作流强制计划确认）→ 步进循环 → critic 终判 → legacy 同款 outcome 汇总
- P4 语义：插件脚本免确认、模型脚本必须确认、runtime.workflowScripts 默认关、动态 ≤8 步禁 script、声明式 ≤20 步
嵌套 deps/agent-squad pin 06934bc → 633e853（StepSpec.Brief，Squad #46）
legacy 执行器本 WP 不动（WP2 退役切换）

Why: Q3 WP1 requires core.WorkflowDef workflows to run as compiled squad
graphs (P4 limits and DeniedTools enforced at the compile entry) so the
legacy SpawnSubagent-compression executor can be retired in WP2.

Evidence: internal/wfcompile conformance (zero model, zero network; script
step runs the real codeorch host like the legacy tests): demo.brief shape
(hitl/prompt+critic/artifact/card mapping, evaluator-optimizer loop budget
= maxRetries+1, needs chain), P4 limits (dynamic >8 rejected, dynamic
script rejected, DeniedTools, critic >3, workflow retries >6), demo.brief
E2E (critic fail->retry->pass, drops record, artifact from step-ref file,
card, hitl sequence without plan confirmation for registered workflows,
BB out_length visible in the draft task brief), critic exhaustion fails
closed, demo.script E2E (plugin script exempt from confirmation, wf.tool/
ask/artifact/step callbacks), workflowScripts off fails, model script
double confirmation with reject paths. Full backend suite green (SELF);
CI authoritative (GATE).

Impact: new package internal/wfcompile (compiler + host IntentRunner +
RunCompiled driver); nested deps/agent-squad 06934bc -> 633e853 (StepSpec
.Brief). No existing backend behavior changes (legacy executor untouched
until WP2).
