+## [Unreleased]
+
+### ✨ 新功能
+
+- **Codex adapter**：新增独立 `codex-plugin/` 适配层，覆盖 Codex CLI 与 Codex App 的生命周期 hook、MCP 检索工具、历史 JSONL 导入、工具输出 offload 与本地 Gateway 自动启动，并包含 Codex App 的额外适配与验证。
+
+### 🔒 安全增强
+
+- Gateway 默认要求 tokenized POST；无 token 时仅保留 loopback GET 探活，loopback tokenless POST 必须显式启用开发开关。
+- Codex adapter 默认拒绝非 loopback Gateway URL，MCP 默认不暴露跨项目检索或完整 offload 内容。
+- Gateway token 文件改为私有权限、owner 校验、atomic create；并发 autostart 不再可能生成互相覆盖的 token。
+- Codex hook 诊断写入私有 `hook.log`，日志内容先经过敏感字段 redaction。
+
+### 🐛 修复
+
+- scoped memory/conversation search 会扩展候选窗口到 store 记录总数，避免当前项目结果被其他项目的前 500 个候选挤掉。
+- `prepack` 不再因为已缺失的历史可选 bin-script 源目录而失败；存在对应 `tsconfig.json` 时仍会构建这些脚本。
+

+# TencentDB Agent Memory Codex Adapter
+
+Codex adapter for the **memory-tencentdb** four-layer memory system
+(L0 conversation capture -> L1 episodic extraction -> L2 scene blocks -> L3
+persona synthesis).
+
+The heavy lifting runs in the Node.js **Gateway** sidecar used by the other
+TencentDB Agent Memory integrations. This adapter is a thin Codex plugin layer:
+it translates Codex hooks and MCP tool calls into the Gateway API, keeps
+Codex-specific state under the adapter data directory, and leaves the OpenClaw
+and Hermes paths unchanged.
+
+The adapter targets Codex as a host, including Codex CLI and Codex App.
+It also includes extra Codex App adaptation and validation for App session
+history, archived JSONL import, plugin-cache loading, and App-observed hook
+behavior.
+
+## Architecture
+
+```text
+Codex (CLI and App)
+  +-- Hooks
+  |   +-- SessionStart        -> scripts/session-start.mjs
+  |   +-- UserPromptSubmit    -> scripts/user-prompt-submit.mjs
+  |   +-- PreToolUse          -> scripts/pre-tool-use.mjs
+  |   +-- PermissionRequest   -> scripts/permission-request.mjs
+  |   +-- PostToolUse         -> scripts/post-tool-use.mjs
+  |   +-- PreCompact          -> scripts/pre-compact.mjs
+  |   +-- PostCompact         -> scripts/post-compact.mjs
+  |   +-- Stop                -> scripts/stop.mjs
+  +-- MCP
+      +-- scripts/mcp-server.mjs
+             +-- tdai_memory_search
+             +-- tdai_conversation_search
+             +-- tdai_offload_lookup
+                    |
+                    v  HTTP (127.0.0.1:8420 by default)
+             memory-tencentdb Gateway
+                +-- POST /recall
+                +-- POST /capture
+                +-- POST /search/memories
+                +-- POST /search/conversations
+                +-- POST /session/end
+                +-- POST /seed
+```
+
+The Codex-specific integration lives in this directory. The shared changes
+outside `codex-plugin/` are limited to host-neutral Gateway and seed support
+used by sidecar clients: a lightweight root metadata endpoint, optional
+`started_at` capture metadata, and opt-in full-pipeline waiting for `/seed`.
+
+## Lifecycle Mapping
+
+| Codex surface | Gateway or local path | Behavior |
+| --- | --- | --- |
+| `SessionStart` | `/recall`, `/search/memories`, selective `/search/conversations` | Restores project/session context and returns Codex `additionalContext` when useful context exists. |
+| `UserPromptSubmit` | Local turn state, `/recall`, `/search/memories`, selective `/search/conversations`, local L0 JSONL fallback | Starts a pending turn, recalls relevant memory, and injects bounded context; if Gateway recall/search has no useful context, scans project-scoped local L0 JSONL as a last resort. |
+| `PreToolUse` | Local turn state | Records tool intent and returns a compact memory/offload hint. |
+| `PermissionRequest` | Local turn state | Records permission activity for the current turn. |
+| `PostToolUse` | Local turn state, context-offload files | Records tool results and can replace large tool output with compact hook feedback plus a lookup reference. |
+| `PreCompact` | `/capture` | Captures pending turn state before compaction. |
+| `PostCompact` | `/session/end` | Flushes pending Gateway pipeline work after compaction. |
+| `Stop` | `/capture`, periodic `/session/end` | Captures the completed Codex turn and flushes every `TDAI_CODEX_FLUSH_EVERY_N_TURNS` captured turns. |
+| MCP `tdai_memory_search` | `/search/memories` | Searches L1 structured memory. |
+| MCP `tdai_conversation_search` | `/search/conversations` | Searches L0 raw conversation history. |
+| MCP `tdai_offload_lookup` | Local context-offload index | Retrieves exact redacted tool results by `node_id`, `tool_call_id`, or query. |
+
+## Reliability Features
+
+- **Gateway supervision** - the adapter can auto-discover and start the Gateway
+  from a local TencentDB Agent Memory checkout, then poll `/health` before use.
+- **Circuit breaker** - repeated Gateway failures pause calls for a short
+  cooldown instead of slowing every hook invocation.
+- **Bounded prompt injection** - empty Gateway search responses are not injected,
+  recall output is capped by `TDAI_CODEX_CONTEXT_MAX_CHARS`, and tool hints are
+  intentionally compact.
+- **Injected-context cleanup** - adapter-controlled capture, import, transcript,
+  and Gateway L0/L1 write paths strip TencentDB/Codex injected blocks before
+  persistence to avoid recall feedback loops.
+- **Local L0 fallback** - when Gateway recall/search is unavailable or empty,
+  automatic prompt recall can stream recent local L0 JSONL and filter by the
+  current Codex project session-key prefix.
+- **Short-term offload lookup** - large `PostToolUse` output can be stored under
+  local JSONL/ref/Mermaid artifacts and retrieved later even if the Gateway is
+  temporarily unavailable.
+
+## Installation Location
+
+This directory (`codex-plugin/`) is the source of truth for the Codex adapter.
+Codex loads it as a local plugin or from a local marketplace/cache copy.
+
+The plugin manifest is:
+
+```text
+codex-plugin/.codex-plugin/plugin.json
+```
+
+It declares the Codex skill, bundled hook config, and bundled MCP server config.
+The adapter also ships a machine-readable reuse contract:
+
+```text
+codex-plugin/adapter-profile.json
+codex-plugin/hooks/hooks.codex.json
+codex-plugin/.mcp.json
+```
+
+Codex can load these hooks as plugin-bundled hooks when `plugin_hooks` is
+enabled, or as user-level hooks from `~/.codex/hooks.json`. When mirroring the
+hook file into a user-level config, replace the plugin-root variable with the
+installed adapter path because user-level hooks do not receive plugin-specific
+environment variables. The bundled MCP config exposes memory search and offload
+lookup tools; the manual `codex mcp add` command below is a fallback for local
+development or older Codex builds.
+
+## Reuse Contract
+
+The adapter is intended to be installable from a copied plugin directory, a
+Codex plugin cache, a package release, or a forked source checkout without
+editing script files. The stable contract is:
+
+- `adapter-profile.json` describes the adapter ID, host, entrypoints,
+  runtime requirements, environment variables, and extension points.
+- Hook and MCP configs refer to the plugin root through Codex-provided root
+  variables instead of machine-specific absolute paths.
+- Per-user state lives under `TDAI_CODEX_DATA_DIR` or the default
+  `~/.memory-tencentdb/codex-memory-tdai`; copied adapters do not share state
+  unless that directory is explicitly shared.
+- Gateway autostart uses the package binary by default, so a copied adapter can
+  run without importing dependencies from the plugin directory.
+- Source-tree development is still supported by setting `TDAI_CODEX_TDAI_ROOT`
+  to a local checkout.
+- Fork, release, and tarball validation can override
+  `TDAI_CODEX_GATEWAY_PACKAGE` without changing the adapter scripts.
+
+Run the doctor before publishing, copying, or handing the adapter to another
+Codex environment:
+
+```bash
+node codex-plugin/scripts/doctor.mjs
+node codex-plugin/scripts/doctor.mjs --start --require-healthy --strict
+node codex-plugin/scripts/query.mjs doctor --json
+```
+
+The doctor checks that manifest entrypoints exist, hook/MCP configs are
+portable, adapter state is writable with private adapter-owned subdirectories,
+the Gateway URL is loopback unless explicitly allowed, and the Gateway can be
+launched from either a source checkout or package binary.
+
+## Setup
+
+From the TencentDB-Agent-Memory repository root:
+
+```bash
+npm install
+```
+
+Optional Codex adapter environment:
+
+```bash
+export TDAI_CODEX_TDAI_ROOT="/path/to/TencentDB-Agent-Memory"
+export TDAI_CODEX_DATA_DIR="$HOME/.memory-tencentdb/codex-memory-tdai"
+export TDAI_CODEX_GATEWAY_URL="http://127.0.0.1:8420"
+export TDAI_CODEX_AUTOSTART=true
+export TDAI_CODEX_FLUSH_EVERY_N_TURNS=5
+# Tool-output offload is enabled by default; uncomment to disable it.
+# export TDAI_CODEX_TOOL_OFFLOAD=false
+```
+
+When the adapter autostarts the Gateway it keeps the service on loopback by
+default, creates a private bearer token under
+`$TDAI_CODEX_DATA_DIR/codex-adapter/gateway-token`, and sends that token on
+Gateway requests. The token is passed to the daemon through `TDAI_TOKEN_PATH`
+instead of a generated token environment variable. Set `TDAI_CODEX_GATEWAY_TOKEN`
+or `TDAI_TOKEN_PATH` if you want to manage the token yourself. Autostart refuses
+non-loopback hosts unless `TDAI_CODEX_ALLOW_NON_LOOPBACK=true` is set explicitly.
+
+By default autostart uses the package bin
+(`npx --yes --ignore-scripts --package @tencentdb-agent-memory/memory-tencentdb tdai-memory-gateway`),
+so the copied Codex plugin does not need to import package dependencies from the
+plugin directory and daemon launch does not run npm lifecycle scripts. For
+source-tree development, set `TDAI_CODEX_TDAI_ROOT` to use
+`npx tsx src/gateway/server.ts` from a local checkout, or set
+`TDAI_CODEX_GATEWAY_PACKAGE` to override the package spec, including a pinned
+version or tarball during release validation. Package-bin launch does not
+hydrate additional shell-only LLM secrets unless
+`TDAI_CODEX_HYDRATE_ENV_FOR_PACKAGE_GATEWAY=true` is set explicitly.
+
+The Gateway also rejects non-loopback browser origins by default and blocks
+credential-bearing `/seed config_override` keys, so imported Codex history cannot
+redirect configured LLM, embedding, TCVDB, or backend credentials to a different
+network endpoint.
+
+When no Gateway token is configured, unauthenticated loopback access is limited
+to `GET` routes such as `/health`. Tokenless `POST` routes require the explicit
+loopback-only development flag `TDAI_GATEWAY_AUTH_DISABLED=true`; non-loopback
+tokenless access is always rejected.
+
+Adapter requests also refuse non-loopback `TDAI_CODEX_GATEWAY_URL` values unless
+`TDAI_CODEX_ALLOW_NON_LOOPBACK=true` is set explicitly. This prevents hooks from
+sending local bearer tokens or captured memory to an unexpected remote URL.
+
+For L1/L2/L3 extraction, configure an OpenAI-compatible LLM for the Gateway:
+
+```bash
+export TDAI_LLM_BASE_URL="https://api.openai.com/v1"
+export TDAI_LLM_API_KEY="..."
+export TDAI_LLM_MODEL="gpt-4o-mini"
+```
+
+The example Gateway config is `tdai-gateway.example.json`. Copy it to:
+
+```bash
+$TDAI_CODEX_DATA_DIR/tdai-gateway.json
+```
+
+or use environment variables only. During autostart the adapter sets
+`TDAI_GATEWAY_CONFIG=$TDAI_CODEX_DATA_DIR/tdai-gateway.json`, because the Gateway
+normally discovers config files from the current working directory or its
+default data directory unless this variable is explicit.
+
+## Register MCP Tools
+
+The plugin bundles `codex-plugin/.mcp.json`, so normal Codex plugin installation
+can register the MCP server from the plugin manifest. For local development,
+or if a Codex build does not load plugin-bundled MCP config, register it
+manually:
+
+```bash
+codex mcp add tdai-memory \
+  --env TDAI_CODEX_TDAI_ROOT="/path/to/TencentDB-Agent-Memory" \
+  --env TDAI_CODEX_DATA_DIR="$HOME/.memory-tencentdb/codex-memory-tdai" \
+  --env TDAI_CODEX_GATEWAY_URL="http://127.0.0.1:8420" \
+  --env TDAI_CODEX_AUTOSTART="true" \
+  -- node "/path/to/TencentDB-Agent-Memory/codex-plugin/scripts/mcp-server.mjs"
+```
+
+MCP search tools are scoped to the current Codex project path by default. Pass
+`all_projects: true` only when you intentionally want cross-project memory or
+offload lookup.
+
+For model-facing MCP safety, cross-project search and exact offload content are
+not exposed by default. To opt in from outside the model context, set:
+
+```bash
+export TDAI_CODEX_MCP_ALLOW_ALL_PROJECTS=true
+export TDAI_CODEX_MCP_ALLOW_OFFLOAD_CONTENT=true
+```
+
+## Diagnostics
+

+```
+
+Logs:
+
+```text
+$TDAI_CODEX_DATA_DIR/codex-adapter/logs/gateway.stdout.log
+$TDAI_CODEX_DATA_DIR/codex-adapter/logs/gateway.stderr.log
+$TDAI_CODEX_DATA_DIR/codex-adapter/logs/hook.log
+```
+
+## Import Existing Codex History
+
+The Gateway supports historical seeding through `POST /seed`. The Codex adapter
+adds a host-specific importer that converts local Codex JSONL rollouts into
+that seed format.
+
+By default it reads:
+
+```text
+~/.codex/sessions/**/*.jsonl
+~/.codex/archived_sessions/**/*.jsonl
+```
+
+The importer is opt-in and runs as a dry run unless `--yes` is provided:
+
+```bash
+node codex-plugin/scripts/import-codex-history.mjs --dry-run --since 30d
+node codex-plugin/scripts/import-codex-history.mjs --yes --since 30d --cwd "/path/to/project"
+```
+
+It skips Codex-generated context scaffolding such as `AGENTS.md` injections and
+imports only paired user/assistant rounds. Use `--no-archived` to exclude
+archived sessions, `--limit` for a small trial import, and `--out` to inspect
+the generated `/seed` payload before writing.
+
+By default, a real import requests `wait_for_full_pipeline`, so Gateway `/seed`
+records L0, waits for L1, flushes L2 scene extraction, and waits for L3 persona
+generation before returning. Use `--no-full-pipeline` when the faster L0/L1-only
+seed behavior is preferred. For large trusted local imports, `--l1-concurrency`
+or `TDAI_CODEX_IMPORT_L1_CONCURRENCY` can raise bounded L1 extraction
+parallelism without changing the live host default. The importer also sends
+`l2_batch_size` by default, which lets Gateway coalesce many short historical
+Codex sessions into larger L2 scene-extraction batches while keeping live
+runtime L2 scheduling unchanged.
+
+## Short-Term Context Offload
+
+Codex does not expose OpenClaw's `slots.contextEngine`, so the adapter uses the
+official Codex hook surface as the equivalent control point:
+
+1. `PostToolUse` evaluates tool-result size against mild, aggressive, and
+   emergency thresholds.
+2. When offload is triggered, the full redacted result is written under
+   `$TDAI_CODEX_DATA_DIR/codex-adapter/context-offload/<session>/refs/`.
+3. A structured `offload-<session>.jsonl` entry is appended with `node_id`,
+   `tool_call_id`, summary, score, policy, and `result_ref`.
+4. The deterministic L2 canvas at `mmds/001-codex-tool-offload.mmd` is rebuilt
+   and injected on later `SessionStart` / `UserPromptSubmit` hooks.
+5. The model can drill down by calling `tdai_offload_lookup`; humans can use
+   `query.mjs offload node ... --content`.
+
+Thresholds are configurable:
+
+```bash
+export TDAI_CODEX_TOOL_OFFLOAD_MIN_CHARS=20000
+export TDAI_CODEX_TOOL_OFFLOAD_AGGRESSIVE_MIN_CHARS=80000
+export TDAI_CODEX_TOOL_OFFLOAD_EMERGENCY_MIN_CHARS=250000
+export TDAI_CODEX_TOOL_OFFLOAD_PREVIEW_CHARS=2000
+export TDAI_CODEX_TOOL_OFFLOAD_AGGRESSIVE_PREVIEW_CHARS=800
+export TDAI_CODEX_TOOL_OFFLOAD_EMERGENCY_PREVIEW_CHARS=240
+```
+
+## Codex Host Notes
+
+OpenClaw- or Claude Code-only interfaces such as host-specific slot APIs are not
+applicable to Codex; this adapter uses Codex hook, MCP, JSONL history, and
+context-injection surfaces instead. Codex can gate plugin-scoped hooks or omit
+optional transcript fields in some builds; the adapter provides Codex-native
+fallbacks through user-level hooks, local session state, tool-event summaries,
+and history import.
+
+## Security Notes
+
+- Adapter-owned session state, gateway tokens, and offloaded tool-result files
+  are written with private owner-only permissions on POSIX filesystems.
+- Tokenized Gateways require `Authorization: Bearer ...` for all routes. A
+  tokenless Gateway exposes only loopback `GET` probes by default; loopback
+  tokenless `POST` routes require explicit development opt-in, and non-loopback
+  tokenless access is rejected.

+description: Use TencentDB Agent Memory from Codex for manual inspection, explicit remembering, and diagnostics. Automatic hooks are the primary path; use this skill only when the user asks about memory state, recall, or saving a specific note.
+---
+
+# TDAI Memory For Codex
+
+This plugin is designed to be automatic:
+
+- `SessionStart` injects project memory and recent raw-conversation hints.
+- `UserPromptSubmit` starts a turn, recalls relevant L1/L2/L3 memory, and injects it as context.
+- If Gateway recall/search has no useful context, prompt recall falls back to a project-scoped local L0 JSONL scan.
+- `PreToolUse` injects a lightweight model-visible memory hint and collects tool activity.
+- `PermissionRequest` / `PostToolUse` collect permission and tool result activity.
+- Large `PostToolUse` results are offloaded into `context-offload/<session>/offload-*.jsonl`, `refs/*.md`, and `mmds/001-codex-tool-offload.mmd`; later prompts inject the compact canvas.
+- `PreCompact` captures pending turn state before compaction.
+- `PostCompact` flushes session-scoped memory pipeline work through `/session/end`.
+- `Stop` captures the completed turn through the TencentDB Agent Memory Gateway and flushes every `TDAI_CODEX_FLUSH_EVERY_N_TURNS` turns.
+- Adapter-controlled capture and import paths strip injected TencentDB/Codex memory tags before persistence, matching the original `before_message_write` cleanup goal even though Codex does not expose that exact hook.
+- `tdai_memory_search` / `tdai_conversation_search` / `tdai_offload_lookup` are available as Codex MCP tools when `scripts/mcp-server.mjs` is registered.
+
+Manual commands are only for inspection or explicit notes:
+
+```bash
+node "${PLUGIN_ROOT}/scripts/query.mjs" status
+node "${PLUGIN_ROOT}/scripts/query.mjs" memory "query terms"
+node "${PLUGIN_ROOT}/scripts/query.mjs" conversation "query terms"
+node "${PLUGIN_ROOT}/scripts/query.mjs" remember "durable note to save"
+node "${PLUGIN_ROOT}/scripts/query.mjs" flush
+node "${PLUGIN_ROOT}/scripts/query.mjs" seed ./historical-conversations.json
+node "${PLUGIN_ROOT}/scripts/query.mjs" offload list --all --limit 10
+node "${PLUGIN_ROOT}/scripts/query.mjs" offload node Cxxxxxx_N001 --content
+```
+
+When memory is retrieved, use it as operating context. Verify path- and data-dependent claims against the current filesystem before acting. If current evidence contradicts memory, trust the current evidence and save the correction.
