 ### What Is Missing
 
+#### Heartbeat and Turn Envelope convergence
+
+Under existing M7.4 and roadmap S2/S3/S6/S8, converge the **execution facts**
+used by heartbeat and Turn hosts, while keeping host effect ownership separate.
+Neither today's large quota packet nor the smaller TurnEnvelope is a target
+shape merely because of its size. Optional memory participation now has one
+compact, signed envelope projection; the Codex CLI adapter preserves default-off
+isolation. This does not qualify installed heartbeat/App adoption or model value.
+
+Remaining implementation Todos, in dependency order:
+
+| Todo | Observable outcome and decisive acceptance |
+|---|---|
+| Reconcile execution/context requirements across heartbeat and TurnEnvelope | Same captured authoritative decision preserves actor/Goal/Todo, required full reads, claim/lease, action selection, replan/closure, conditional settlement and scheduler ownership. Inventory omitted/duplicated facts before deleting render branches. Include optional capabilities off, recall-only, ingest-only, stale binding and provider failure; private detail is accessed only through authorized references. |
+| Adopt one typed projection in real host renderers | Heartbeat full/thin and Turn host consume the same execution facts and per-Turn capture/detail route. Keep host-specific notification and scheduler transport explicit. Real File/SQLite CLI plus packaged Codex App tests cover reentry, source loss, refusal before required reads, late results, backoff and exactly-once settlement; no second admission from a detail read. Retire the replaced projection only after its last caller moves. |
+| Qualify the context shape and migration default | Compare the same normal, replan, wait/recovery and optional-capability workloads against both current full and compact paths. Measure payload/model tokens, detail IO, latency, resource growth, omissions and decision/outcome quality. Keep data loss, duplicate effects, identity and settlement errors as hard constraints. Preserve supported saved prompts/receipts and reversible rollout; change budgets or defaults only with that evidence. |
+
+Do not add a generic executor or lower an acceptance threshold to make a short
+packet pass. Preserve unsatisfied requirements and distinguish transport parity,
+installed host adoption and useful model outcomes. See the
+[current envelope contract](../../reference/protocols/turn-envelope-v0.md#optional-memory-participation).
+
 - A generic shared executor is deliberately absent. The current adapters share
   plan/receipt algebra but have different execution ownership, so M7.3
   is closed with no follow-up rather than filled with a speculative framework.

 ### 还缺什么
 
+#### Heartbeat 与 TurnEnvelope 收敛
+
+沿用既有 M7.4 与 roadmap S2/S3/S6/S8，统一 heartbeat 和 Turn host 消费的
+**执行事实**，宿主效果的所有权仍分别保留。现有大 quota packet 与小 TurnEnvelope
+都不是仅凭大小就合理的目标形态。可选 memory 参与事实现进入一个有界、签名覆盖的
+envelope 投影，Codex CLI 保持关闭隔离；这不代表安装态 heartbeat/App 或模型收益
+已验收。
+
+后续实施 Todo 按依赖顺序推进：
+
+| Todo | 可观察结果与决定性验收 |
+|---|---|
+| 核对 heartbeat 与 TurnEnvelope 的执行和上下文要求 | 同一捕获的权威决策保留 actor/Goal/Todo、必读全文、claim/lease、选择、replan/收尾、带条件结算和 scheduler 所有权。删除渲染分支前列明遗漏与重复事实。覆盖可选能力关闭、仅 recall、仅 ingest、绑定失效和 provider 失败；私有详情只经有权限的引用访问。 |
+| 在真实宿主 renderer 采用同一 typed 投影 | heartbeat full/thin 与 Turn host 消费同一执行事实及同 Turn 捕获/详情入口；显式保留通知和 scheduler 的宿主传输。真实 File/SQLite CLI 与打包 Codex App 覆盖重入、来源丢失、必读前拒绝、迟到结果、backoff 和一次结算；补读不触发第二次准入。最后调用方迁移后才退役旧投影。 |
+| 核验上下文形态及迁移默认 | 将相同的正常、replan、等待/恢复与可选能力负载同时对照当前完整和短包路径，测量载荷/model token、详情 IO、延迟、资源增长、遗漏、决策与结果质量。数据丢失、重复效果、身份和结算错误保持硬约束；保留受支持的已保存 prompt/回执与可逆 rollout，根据证据再改预算或默认。 |
+
+不引入通用 executor，也不降低验收门槛来让短包通过。保留未满足要求，分别记录
+传输等价、安装态宿主采用和有效模型结果。见
+[当前 envelope 契约](../../reference/protocols/turn-envelope-v0.md#optional-memory-participation)。
+
 - 通用共享 executor 被有意保留为空。当前 adapter 共享 plan/receipt algebra，却拥有不同的执行边界，因此 M7.3 应以 no-follow-up 关闭，而不是用推测性 framework 填充。
 - 常规 LoopX 核心路径仍需逐条做有界采用判断。只有当路径包含多步 external effect、单一稳定 identity、durable receipt、replay 要求，并且变更能删除重复 settlement truth 时，才应该使用这套 algebra。
 - Race/CAS qualification 推迟到真实并发执行入口出现后；同步 adapter 本身不足以证明需要并发基础设施或测试。

+### Optional memory participation
+
+The compact boundary retains the verified Goal/Agent Reward Memory automation
+facts in `boundary.capabilities.reward_memory`: `automatic_recall` and
+`automatic_ingest`. Unconfigured, disabled or unavailable bindings omit this
+projection. It carries neither private provider configuration nor memory content
+and grants no action authority. Existing action-signature coverage includes it.
+
+Codex CLI host requests use these facts together with the fresh runtime binding
+readback. Recall guidance is added only with enabled recall and actual context;
+the reflection instruction and output-schema field appear only with enabled
+ingest. A disabled or stale recall packet cannot activate either operation.
+Older/custom hosts may still return a reflection field: while ingest is off the
+adapter ignores it before validation and journaling, preserving ordinary work.
+When enabled, bounded reflection validation, exact independent attestation and
+post-settlement ingest retain their existing rules. Provider failure remains
+fail-open. The host adapter is Python IO transport over the existing capability
+resolver and TypeScript envelope owner, not a new enablement policy.
+
+This is a bounded shared-facts step. Heartbeat still has its existing full and
+compact rendering paths; it is not yet the same installed host journey. The
+remaining convergence work is tracked in the existing
+[effect-interpreter RFC](../../architecture/rfcs/agent-loop-effect-interpreter-v0.md#heartbeat-and-turn-envelope-convergence).
