+## opencode {VERSION}
+
+{Prerelease/Stable} release from `{branch}` branch. Session todo reminders, per-series release notes, truthful MEMORY state, and DAG output-duplication fixes.
+
+---
+
+### 🎯 Features
+
+- **Stale todo reminders (PR #394)**: sessions with uncompleted todos now inject a one-shot synthetic reminder on every model step, including steps without tool calls, so stale items stay visible to the model until they are completed or cancelled; sub-agent sessions track their own todos, and a freshness guard skips the reminder right after a successful todowrite call.
+- **Per-series release notes (PR #394)**: each release series renders its GitHub Release body from `.github/releases/vX.Y.Z.md` with fail-closed validation before `gh release create`; a missing or invalid series file stops the release instead of shipping placeholder notes.
+- **/dag-auto as pure workflow routing (PR #393)**: `/dag-auto` no longer embeds orchestration logic of its own and only routes to workflows; `/dag-init`, `/dag-flow`, and `/dag-template-update` are retired.
+
+---
+
+### 🐛 Bug Fixes
+
+- **DAG prompt and structured-output duplication, #386-388 (PR #390)**: schema-node prompts and the `submit_result` tool description now state a single authority contract (summary only in the payload, no restating in the body, end the turn after a successful submit); block compilation drops instructions that merely duplicate the objective; crash recovery reuses the live output-file-reference capture so durable receipts match between live and recovered runs.
+- **MEMORY silent-failure cluster, #395-397 (PR #398)**: the response schema is now rendered into the system prompt for schema-blind providers whose `response_format` downgrade made every topic commit fail validation; `/memory` replies report the true state instead of a hardcoded "Memory remains off"; `statusReason` surfaces the model gate so an enabled config whose model no longer resolves reads as unavailable instead of "on" and inert.
+- **CI acceptance workflow rollback (PR #400)**: the specgit-accept pnpm rewrite that broke `Setup pnpm` on the first main-target PR was rolled back to the verified node22 + `npm i -g specgit@^0.5.0` install, keeping the main-only trigger.
+
+---
+
+### 🧪 Test Summary
+
+```
+CI gates on the dev-to-main promotion (PR #399):
+Typecheck:           pass
+Unit Tests (linux):  pass
+E2E Tests (linux):   pass
+E2E Tests (windows): pass
+SpecGit Acceptance:  pass
+```
+
+---
+
+### 🔍 Verification
+
+- Provider wire behavior behind the MEMORY fixes is pinned by `test/memory/model-wire.test.ts`; the todo-reminder run-loop guarantees are pinned by `test/session/todo-reminders.test.ts` (empty-list skip, settled-list skip, freshness guard, failed-write guard).
+- MEMORY was verified end-to-end against the live provider: a checkpoint run over an initialized git project committed a real memory topic; topic id, Memory home path, and timings are recorded in the release-remediation workflow evidence.
+- Every delivery in this batch (PRs #390, #393, #394, #398, #400) shipped through the specgit harness with an accepted verdict, and all promotion gates are green on PR #399.

+# Release Train（发布列车）
+
+一条从 issue 清理到正式发版的批次交付循环。全程 SpecGit 化：issue → delivery PR → CI 门禁 → 合并 → 发版。所有条目先处理完，再统一处理 PR 问题——batch 住操作，不逐个排队。
+
+## Trigger
+
+人工发起：用户说"发版 / 跑一趟发布列车"，且满足发车条件——dev 上无开放 delivery PR。
+
+## Steps
+
+1. **验车**：确认 dev 分支 CI 全绿（push 触发的 Typecheck + 全量测试），open issue 与已合入 dev 的交付一一对应。注意：issue 只在 dev→main PR body 含 closing keywords（`Closes #N`）时才自动关闭——开升级 PR 时必须带上本班次的全部 closing 行。
+2. **复盘**：对目标子系统做完整性复盘（每次发车指定一个；本轮为 MEMORY ON：`/init` 盖章 `project.time_initialized` → `/memory on` → `memory_search` 可用的启用链路，外加写入路径验证）。发现按 specgit 粒度开 issue——一个独立可验证的 WHY 一个 issue。
+3. **Checkpoint（唯一的阻塞确认）**：呈现复盘报告——发现清单、新建 issues、修复计划、本班车范围——一次确认。确认后连续执行到发版，不再打断。
+4. **修复班车**：`specgit issue <n> <n> ...` 把全部新 issue 绑进一个 delivery（多 issue 一 PR），从 dev 切出 `fix/**` 分支，TDD 修复，PR → dev。PR 上 CI/TDD 失败 → 原 delivery 内追加 commit 修复；已合入 dev 后才暴露的回退 → 开新 fix issue 进下一班车。
+5. **升级**：修复 PR 合并、dev push 全量绿后，立即开 dev → main PR（protect-main 全量门禁：Typecheck + Unit Tests + E2E 双平台），body 带本班次全部 closing keywords。全程监控，失败即修。
+6. **发版**：main 合并后、触发 `release-fork` 前，先写 series 文件——按 `.github/RELEASE_NOTES_TEMPLATE.md` 渲染并提交 `.github/releases/vX.Y.Z.md`。版本号是 `release-version.ts` 的机械推导（`graphagent-v*` 标签上的 patch+1，不读 commit 类型），系列文件必须以推导出的版本命名；渲染 fail-closed，失败即阻断发版。随后 `release-fork` 触发正式版。
+7. **Brief**：一趟车一份收尾汇报——本班次 issue 清单、PR、CI 结论、版本号与 release 链接、遗留（进下一班车的条目）。
+
+## Rules
+
+- SpecGit 铁律优先：`specgit finish` 非 0 不请求合并；不削弱 policy；只认 `--json`。
+- 发布已由步骤 3 的确认授权，正式版不再二次询问。
+- 回退（合并后 CI 挂）永不静默：开 issue、进下一班车、在 Brief 中显式列出。
