[Unreleased]

[0.6.0] - 2026-06-01

Minor release — Core 0.6 gateway protocol upgrade, AgentOps event surface and release hardening.

Published to hex.pm and hexdocs.pm, checksum 8674905211ab7612d388dbc2ee7fd034bffc9acc8b67db545c2b8eaa6f273e60.

Added

Core 0.6 session/control surface:
- POST /v1/sessions now accepts a safe whitelist of v0.6 fields including groupId, hibernateAfterMs, eventBufferSize, memory, subagents, interruptImmuneTools and responseFormat with camelCase/snake_case compatibility.
- POST /v1/sessions also accepts bounded safe messages JSON import for user / assistant / tool_result history continuation and rejects public JSON skillSelector module injection.
- GET /v1/sessions/:id/events supports session replay via since, types and Last-Event-ID; status/stats expose lastEventIndex and eventBufferCount.
- GET /v1/groups/:group_id/events streams group-level SSE events via CMDC.EventBus.subscribe_group/1, adding sessionId to each event data payload.
- POST /v1/sessions/:id/tools/batch exposes allowlisted atomic attach/detach/replace for core batch tool APIs and surfaces tools_updated to SSE/WS clients.
- PATCH /v1/sessions/:id/plugins/:plugin/opts calls CMDC.update_plugin_opts/3 behind :plugin_opts_allowlist and translates plugin_opts_updated.
- POST /v1/sessions/:id/checkpoints and POST /v1/sessions/resume expose checkpoint/resume without accepting client-supplied checkpoint backend modules.
- Admin-only /v1/provider_profiles endpoints and startup :provider_profiles config register Provider Registry profiles without accepting JSON resolverFn; responses expose option keys only.
EventTranslator v0.6 event surface:
- Current core shapes for model_switched and tool_call_unknown are now first-class while legacy shapes remain accepted.
- Control/runtime events now include model switch failures, batch tool updates, tool metrics/blocks, stream errors, context overflow, prompt queue/drop/reject, agent resume, abort tool kills, compaction and subagent events.
- Persistence/memory events now include auto_checkpoint_saved and episodic memory plugin events.
- SSE supports ?mode=audit, projecting covered core events through CMDC.AuditEvent into audit_event payloads while skipping noisy token delta events.
Workflow / AgentOps event adapter:
- CMDCGateway.WorkflowEventAdapter translates cmdc_orchestrator 0.6 RunEvent/human_task ledger shapes from plain maps, tuples or structs without depending on CMDCOrchestrator at compile time.
- Standard workflow events now cover run/node lifecycle, fork/join node lifecycle, signal edges and human_task create/progress/decision/ complete/timeout/fail events.
- GET /v1/workflows/runs/:run_id/events provides read-only paginated replay from a server-configured :workflow_event_source; without a source it returns workflow_event_source_not_configured.

Changed

Phase 20 upgrade path targets cmdc_gateway 0.6.0 directly. The A2A terminal/webhook fixes are folded into the minor release; publish a 0.5.1 hotfix only if an existing production deployment needs the A2A fix before the full core 0.6 surface is ready.
Hex dependency baseline moves to cmdc ~> 0.6; :telemetry is now declared directly because gateway emits webhook dead-letter telemetry itself.
Agent Card now advertises core 0.6 group events, plugin opts update, checkpoint/resume, Provider Registry control-plane endpoints and audit projection plus A2A JSON-RPC, webhook, task polling, workflow replay, session replay, batch tool control and safe message import capabilities.
Session/status/stats JSON includes group/workspace metadata and core token_usage / cost_usd summaries while preserving existing dashboard fields.
REST/WS control calls now preserve explicit autoResume: false; model switch accepts strict providerOpts; abort accepts snake_case kill_tools and clear_queue.
README/API docs now document the cmdc ~> 0.6 install baseline, 0.6 session options, SSE replay, group SSE, workflow replay, plugin opts, checkpoint/ resume, Provider Registry, A2A/webhook endpoints and SDK compatibility notes.

Compatibility

Existing REST/SSE/WebSocket clients remain compatible with 0.5-era fields and status codes; 0.6 additions are new fields or new endpoints.
/v1/sessions/:id/tools remains callback tool registration. Core Tool batch attach/detach/replace lives at /v1/sessions/:id/tools/batch.
Public JSON still rejects module/resolver/backend injection paths; SDKs should move those concerns to server-side Elixir configuration.

Security

Session creation now validates workingDir against a server-side CMDCGateway.WorkingDirPolicy root before starting an Agent. The gateway rejects .., ~, filesystem-root escape, non-directory targets and symlink path segments, so cmdc 0.6 Sandbox.Local virtual mode cannot be bypassed by choosing an unsafe sandbox root.
Batch tool control is guarded by :tool_module_allowlist; attach/replace do not accept unknown modules or arbitrary JSON-created atoms.
Gateway deliberately does not expose public JSON for skill_selector, global telemetry audit streams, group replay, or CMDC.monitor/1 process monitors.

Fixed

A2A translate_event/2 now handles the current EventTranslator.translate/1 return shape ({:ok, event_type, data}) and maps terminal {:agent_end, messages, usage} events correctly for sendSubscribe / webhook completion.
REST and WebSocket respond now call CMDC.user_respond/3, preserving the core agent_resumed event instead of broadcasting :user_responded by hand.
Router JSON field lookup now preserves explicit false values instead of treating them as missing.

[0.5.0] - 2026-05-31

Minor release — Phase 18F RAG / GraphRAG AgentOps trace sync。

已发布到 hex.pm + hexdocs,checksum e67f19ad3a68454057fe7798d3779735ae947493902fc7ed9a96664a7810bef2。

Added

CMDCGateway.EventTranslator 支持 cmdc_rag_arcana Phase 18 三元 plugin events，并映射为标准 SSE/WebSocket event： rag_acl_blocked、rag_retrieved、rag_answered、 rag_citation_used、rag_pipeline_step、rag_ingestion_progress、 rag_reembed_progress、rag_graph_progress、rag_graph_audit、 rag_eval_progress。
RAG tool 成功结束时，tool_execution_end 继续保留兼容字段 result，同时新增 rag 结构化摘要，覆盖 citation、grounding、 pipelineRunSummary、graphEvidence、graphStatus 与 ingestStatus。

Security / Privacy

RAG trace payload 默认移除 text / chunk_text / content / prompt / chunks / raw_results / results 等正文或 chunk 字段，只保留 provenance、计数、状态与治理摘要。

Changed

Hex 依赖基线升级为 cmdc ~> 0.5。

[0.4.2] - 2026-05-18

Patch release — repository URL normalization + documentation cleanup. No code changes, no behavior changes.

Repository URL → https://github.com/tupleyun/cmdc_gateway
Module moduledoc + inline comments rewritten to neutral technical descriptions (removed internal task numbering)

[0.4.1] - 2026-05-16

Patch release — webhook 可靠性闭环 + A2A 协议补全。纯加性变更，与 v0.4.0 完全向后兼容。

主库 cmdc 在 v0.4.1 不变（保持 0.4.0 为最新），本 patch 仅升级 Gateway。{:cmdc_gateway, "~> 0.4"} 自动拉到 0.4.1。

Added — A2A `tasks/get` 兜底查询

补全 v0.4 留尾的「webhook 派发失败 / 客户端漏接收时无法查询 task 状态」痛点：

GET /v1/a2a/tasks/:task_id 新端点：返回 task 当前 status / last_event / payload / updated_at / ttl_until
CMDCGateway.TaskStore 新模块：ETS-backed 短期缓存（默认 TTL 10 分钟），由 CMDCGateway.A2A 在每次 webhook 派发时同步刷新
- put/4、get/1、delete/1、list_recent/1、gc_now/0 公共 API
- 后台 GenServer 每 60s GC 过期条目
- 不持久化（重启即清，仅做"短期兜底"，与 12M.1 dead-letter 职责正交）
A2A dispatch_webhook/5 内部每次派发同步 TaskStore.put，让 GET 端点能立即拿到 accepted / status_update / artifact_update / completed / failed 5 类状态

Added — Webhook Dead-Letter 持久化

把 v0.4.0 「webhook 派发失败仅 log」升级为「失败 → 持久化 → BEAM 重启后自动重试」的可靠性闭环：

CMDCGateway.Webhook.DeadLetter behaviour — 4 callback： init/1 / save_failed/2 / list_pending/1 / delete/2 / mark_retried/3。任意 backend 实现统一接口
CMDCGateway.Webhook.DeadLetter.DETS —— 默认 backend：DETS 文件持久化，BEAM 重启后自动 reload；零外部依赖；auto_save: 5_000ms 保护
CMDCGateway.Webhook.Dispatcher —— 调度器 GenServer：
- 启动时按 enabled? opt 决定是否开始调度（默认 true，可通过 WEBHOOK_DLQ_ENABLED=false 关闭）
- 每 tick_interval_ms（默认 30s）扫一遍 pending → 到时间的条目重新调 Webhook.dispatch
- 派发成功 → DeadLetter.delete 清除
- 派发失败 → DeadLetter.mark_retried 推后下一次重试（指数退避， base 30s / cap 1h / 默认 max 10 retries）
- 达到 max_retries → 永久放弃 + Logger.error + emit telemetry [:cmdc_gateway, :webhook, :dead_letter, :permanent_failure]
- 公共 API：enqueue/4、tick_now/0、stats/0（含 pending_count / total_retries / total_succeeded / total_permanent_failures）
A2A.dispatch_webhook/5 自动入队：3 次同步重试失败后 → 调 Dispatcher.enqueue 入 dead-letter。Dispatcher 未启动 / 不可用时退化为原始 error tuple（无 regression）

Added — Webhook Receiver 客户端示例

cmdc_gateway/examples/a2a/ 新增两个开箱即用的 webhook 接收端示例，含 HMAC-SHA256 验签与 5 类 event payload 解析：

webhook_receiver.exs —— Elixir Plug.Cowboy 实现
- 自包含 Mix.install([{:plug_cowboy, ~> 2.7}, {:jason, ~> 1.4}]), 单文件即可跑
- 自定义 body_reader 缓存 raw bytes 给签名校验用
- :crypto.hash_equals/2 常数时间比较（OTP 25+），老 OTP 自动降级
webhook_receiver.mjs —— Node.js Express 实现
- crypto.timingSafeEqual 防 timing attack
- JSDoc 类型定义覆盖 5 类 payload
- --self-test 内置签名算法验证
examples/a2a/README.md —— 协议演进时间线表 + 各 receiver 运行命令 + 端到端测试 curl 示例

Changed — `examples/a2a/README.md` 协议速查表

端点	阶段	说明
`POST /v1/a2a/tasks/send`	11C	JSON-RPC 同步
`POST /v1/a2a/tasks/sendSubscribe`	11C	JSON-RPC + SSE 流式
`POST /v1/a2a/tasks/sendWithWebhook`	v0.4.0	JSON-RPC + webhook 异步
`GET /v1/a2a/tasks/:task_id`	12M v0.4.1	兜底查询（ETS 10min）

配置参考

# config/runtime.exs（推荐）
config :cmdc_gateway, CMDCGateway.Webhook.Dispatcher,
  enabled?: true,
  backend: CMDCGateway.Webhook.DeadLetter.DETS,
  backend_opts: [file: ~c"/var/cmdc/webhook_dlq.dets"],
  tick_interval_ms: 30_000,
  max_retries: 10

环境变量快速配置：

WEBHOOK_DLQ_ENABLED=false — 关闭 dead-letter 调度
WEBHOOK_DLQ_FILE=/path/to/dlq.dets — DETS 文件路径
默认值：enabled?=true，文件位置 System.tmp_dir!()/cmdc_gateway_webhook_dlq.dets

Tests

test/cmdc_gateway/task_store_test.exs — 14 测试（put/get/TTL/GC/ delete/list_recent + event → status 推导）
test/cmdc_gateway/webhook/dead_letter_test.exs — 5 测试 （build_entry + next_retry 指数退避）
test/cmdc_gateway/webhook/dead_letter_dets_test.exs — 8 测试 （DETS round-trip + 持久化 reload + 幂等删除）
test/cmdc_gateway/webhook/dispatcher_test.exs — 4 测试（init 降级 + enqueue + stats + tick 未到期跳过）
test/cmdc_gateway/a2a_test.exs — +4 新测试（GET tasks/:id TaskStore 命中 / 404 / TTL 过期 / status 推导）
全量 160 tests / 0 failures（v0.4.0 125 → v0.4.1 160，+35 新增）
mix compile --warnings-as-errors / mix format --check-formatted / mix credo --strict 路径全通

留给 v0.4.2 / v0.5

webhook artifact_update（message_delta）throttle 机制（v0.4 全归并为 status_update 避免风暴；v0.4.2 可选 throttle 后开启 artifact_update）
A2A 多轮对话 sessionId 默认复用（v0.4.0 起步阶段每次 task 是独立 session，v0.5 计划补 sessionId 复用语义）
A2A Push notifications 完整模式（v0.5）

[0.4.0] - 2026-05-16

Minor release — A2A Protocol 第 4 种交互机制 webhook 模式落地，补齐 sync / SSE / webhook 三大长任务交互入口；依赖升级到 cmdc ~> 0.4，自动获得核心库 v0.4 全部能力（Checkpoint / Backend / Skill v2 / 3 新内置 Plugin / Telemetry）。No breaking changes against v0.3.x。

Added — A2A Webhook 异步交互模式

A2A 协议 4 种交互机制中，v0.3 已实现 sync (/tasks/send) + SSE (/tasks/sendSubscribe)，唯独缺 webhook。SSE 在家庭路由器 / NAT 环境下普遍被 60 ~ 300 秒空闲超时杀连接，对 deep_research / ralph_mode 这种 >5 分钟的长任务是硬伤。v0.4 补齐：

POST /v1/a2a/tasks/sendWithWebhook — JSON-RPC 2.0 扩展端点：接收 callbackUrl（必填）+ webhookSecret（可选，用于 HMAC 签名）+ id / message / sessionId / timeout_ms；立即返回 {taskId, status: "accepted"}，Agent 任务在后台 Task 进程内异步执行
CMDCGateway.Webhook 新模块：HMAC-SHA256 签名 + 派发 + 指数退避重试
- sign_payload/2 + verify_signature/3 —— 用 :crypto.hash_equals/2 （OTP 25+，常数时间比较防 timing attack；老 OTP 自动降级到 byte_size
  - 逐字符）
- build_payload/3 —— 标准 payload schema（event / taskId / timestamp / schemaVersion: 1 + extra）
- dispatch/3 —— 同步 POST + 3 次指数退避（1s / 2s / 4s），失败 log error；HTTP 客户端用 Erlang 内置 :httpc（零额外依赖）
CMDCGateway.A2A.start_with_webhook/3 —— Webhook lifecycle 编排：
- 立即派发 task.accepted webhook
- subscribe EventBus；翻译 5 类 A2A 生命周期事件回调：
  - task.accepted —— Task 接受，session 已创建
  - task.statusUpdate —— Agent 状态变化（working / tool_calling 等）
  - task.artifactUpdate —— 流式 message_delta（可选）
  - task.completed —— Agent 正常结束 + 完整回复
  - task.failed —— Agent abort / timeout / error
- 派发失败：3 次指数退避后仅写 log（v0.4.0 不持久化重试，留 v0.4.1）

Signature 验签示例

# 客户端发起
curl -X POST https://your-gateway/v1/a2a/tasks/sendWithWebhook \
  -H "X-API-Key: $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0", "id": 1, "method": "tasks/sendWithWebhook",

      "webhookSecret": "shared-secret-123",
      "message": {"role": "user", "parts": [{"type": "text", "text": "..."}]}
    }
  }'

# 立即返回

Changed — 依赖升级

{:cmdc, "~> 0.4"} —— 升级到核心库 0.4.0，Gateway 自动获得 cmdc 0.4 全部能力：
- CMDC.Checkpoint —— 配 Backend.DETS 可让 Session 在 BEAM 重启 / Gateway 滚动更新后无缝恢复
- CMDC.Backend.Composite —— prefix 路由后端，Gateway 单 Session 可同时挂 Sandbox.Local (默认) + Memory.PG (/memories/*) + ETS (/conversation_history/*)
- 3 新内置 Plugin —— LargeResultOffload（200KB+ tool result 写 /large_tool_results/* 不污染 message history）、ContentPolicy （LLM-as-Judge 越狱 / 离题拦截）、EpisodicMemory（成功 session 自动转 few-shot 复用）
- CMDC.Telemetry —— 标准 :telemetry 事件契约（[:cmdc, :llm, :request, :start/:stop] 等 6 个事件），无侵入接 Langfuse / LangSmith / Tempo
- CMDC.Skill v2 —— 加 license / compatibility / metadata Anthropic spec 字段；Skill 文件 10MB 上限防 DoS

tasks/get REST 端点 + ETS 缓存最近 10 分钟 task 状态（webhook 派发失败时给客户端兜底查询）

[0.3.0] - 2026-05-16

Minor release — A2A Protocol Task endpoints + Gateway-level Guardrails

alignment with cmdc 0.3.0 core. No breaking changes against v0.2.x.

Added — A2A Protocol Task Endpoints

Implement A2A (Agent-to-Agent) JSON-RPC 2.0 Task protocol, making CMDC Gateway a first-class A2A-compliant Agent runtime callable from any ADK / LangGraph / CrewAI / external Agent that speaks A2A.

POST /v1/a2a/tasks/send — synchronous JSON-RPC Task invocation; idempotent on taskId; returns final Task result map; goes through Auth → RateLimit → Guardrails Plug chain
POST /v1/a2a/tasks/sendSubscribe — SSE streaming variant emitting TaskStatusUpdateEvent / TaskArtifactUpdateEvent with heartbeats
CMDCGateway.A2A — new module: JSON-RPC handler + Task lifecycle (handle_send / start_subscribe); maps A2A Task semantics onto existing Session API
CMDCGateway.SSEHandler.stream_a2a/3 — A2A-flavored SSE stream that translates CMDC events to A2A Task lifecycle event schema

Added — Gateway Guardrails

CMDCGateway.Plugs.Guardrails — HTTP-layer input/output filter: denylist keywords, max prompt size, sensitive content rejection; mounted in the Router Plug chain after Auth + RateLimit, before dispatch; pluggable via application config

Added — A2A Client SDK Examples

Three runnable client samples proving external A2A agents can call this gateway end-to-end (discover → send → subscribe):

examples/a2a/curl_examples.sh — raw HTTP / SSE walkthrough
examples/a2a/elixir_send.exs — Mix-runnable Elixir Req client
examples/a2a/node_send.mjs — Node.js fetch-based client
examples/a2a/README.md — quickstart with environment setup

Added — Performance Baselines

benchmark/event_translator.exs — Benchee suite for CMDC.Event.t() → A2A TaskStatusUpdateEvent translation throughput
:benchee ~> 1.3 added as :dev / :test dependency

Changed — Dependency Upgrade

{:cmdc, "~> 0.3"} — pick up all 13 RFC items from cmdc 0.3.0 core (most notably: :tool_execution_metrics event, :after_turn Plugin hook, batch attach_tools/2, error-tuple public API #B21)

Quality

mix credo --strict — 0 issues (clean)
All A2A endpoints covered by test/cmdc_gateway/a2a_test.exs
Existing 107 tests + new A2A coverage all green

[0.2.0] - 2026-04-24

Added — A2A Inter-Agent Communication

CMDCGateway.AgentCard — 生成 A2A 兼容的 Agent Card JSON（capabilities + endpoints）
GET /.well-known/agent.json — 免认证暴露 Agent Card，供其他 A2A Agent 发现

Added — Guardrails & Safety Control Plane

POST /v1/sessions/:id/switch_model — 运行时切模型（RFC C8，async 202）
POST /v1/sessions/:id/attach_tool — 运行时加载工具（RFC C9）
DELETE /v1/sessions/:id/tools/:name — 运行时卸载工具（RFC C9）
POST /v1/sessions/:id/steer — 中段注入指令
POST /v1/sessions/:id/abort — 结构化 abort，支持 reason/kill_tools（RFC B6，async 202）
GET /v1/sessions/:id/status — 扩展 session status（pending + queue_sizes，RFC C11）
POST /v1/sessions 新增 userData + promptMode 透传

Fixed — Meter 自动订阅修复（P0）

Meter.init/1 启动时 EventBus.subscribe_all/0 全局订阅
自动 record_token_usage/2 on {:agent_end, _, %CMDC.TokenUsage{}} 事件（支持 cached/reasoning/cost_usd 细粒度字段）
移除对 {:prompt_received} 的订阅，避免与 Router 手动 record_prompt/1 重复计数

Changed — EventTranslator 白名单扩容

新增 7 种事件翻译：model_switched、tool_attached、tool_detached、 tool_call_unknown、memory_flushed、plugin_event、steering

Changed — 依赖与质量

{:cmdc, "~> 0.2"} 依赖升级
新增 excoveralls 开发依赖
Router 的 CMDC.steer/2 返回值修正（移除永不匹配的 :ok 子句）
switch_model/abort 改为 202 Accepted + async: true（cast 语义）
