release: 0.18.1 (0.18.0 had ghost-frame bug, deprecated)

`debug:true` does NOT force full-frame writes — Ink's docs are explicit that
each update is rendered as a SEPARATE output without overwriting the previous
one. Every keystroke triggered a React rerender → a fresh frame appended to
scrollback. After a session, dozens of stale PromptInput frames remained
above; relaunching reasonix made the new session's typing look like it was
"syncing" with the ghost frames above.

The original justification ("log-update drops frames on Windows ConPTY") was
my speculative misread — never seen in practice. Default log-update diff
mode is correct here.

+# Contributing to Reasonix
+
+Thanks for showing up. Reasonix is a small, opinionated codebase
+maintained primarily by [@esengine](https://github.com/esengine);
+PRs are welcome, but read this first so the round-trip is short.
+
+## Setup
+
+```sh
+git clone https://github.com/esengine/reasonix
+cd reasonix
+npm install
+npm run dev          # tsx src/cli/index.ts — live source
+```
+
+Node ≥ 20.10. No global install needed during development.
+
+For stack, layout, scripts, see [`REASONIX.md`](./REASONIX.md).
+
+## Proposing changes
+
+- **Bug fixes** — go ahead and open a PR. Include a reproduction.
+- **New features / behavior changes** — open an issue first to align
+  on scope and approach. Reasonix tries to stay small; "we could add
+  X" PRs that arrive cold are usually rejected or scoped down.
+- **External MCP servers, plugins, presets** — a thin wrapper is
+  fine; a sprawling integration is better hosted as a separate
+  package that depends on `reasonix`.
+
+## Code rules
+
+These are enforced by review and (where possible) by
+`tests/comment-policy.test.ts` — which runs under `npm run verify`
+and gates pre-push.
+
+### Comments — default is none
+
+Write a comment ONLY when **why** is non-obvious and removing the
+comment would confuse a future reader. Justified examples:
+
+- a hidden constraint (`// Yoga miscounts wrap → must clamp to width-1`)
+- a workaround for a specific bug
+- a subtle invariant the type system can't express
+
+Don't write:
+
+- **What the code does.** Names already say it. No `// when x is positive`
+  above `if (x > 0)`.
+- **Module-level essays.** Multi-paragraph docstrings at the top of a
+  file are dead weight. Two short lines max.
+- **Conversation history.** No "user reported X", "screenshot showed
+  Y", "v0.13.2 introduced Z". That belongs in commits / PR text.
+- **Section banners.** `// ─── helpers ───` is noise; group by export.
+- **Restated parameter docs.** If `function pad(f, top, right, bottom,
+  left)`, no `@param top - top padding`.
+
+If a comment is justified, **one line is almost always enough**.
+Comments needing 4+ lines usually mean the code itself needs to be
+clearer (rename, extract, simplify) before any comment is added.
+
+### TypeScript
+
+- Strict mode. No `any` without a `// biome-ignore` and a reason.
+- Prefer narrow types over option bags; if a function takes 5+
+  optional flags, split the responsibilities.
+- Don't re-export types just so two files can share them — move the
+  type to the file that owns the concept.
+
+### Libraries over hand-rolled
+
+If a problem has a well-maintained npm library, use it. Specific
+landmines this project has hit:
+
+- Visual width / unicode width → `string-width`
+- Grapheme segmentation → `Intl.Segmenter`
+- ANSI strip → use what `string-width` ships with
+- Color → use `theme.ts` constants, not raw hex in component code
+
+If a lib is missing a case, file the issue upstream and add a thin
+wrapper — don't fork a local table.
+
+### Files
+
+- One responsibility per file. New code goes in new files when an
+  existing one is already large.
+- File header comment: zero or one line.
+- No `index.ts` re-exports unless they meaningfully shrink the
+  public surface.
+- Don't create new `*.md` documentation files unless explicitly
+  asked.
+
+### Errors / fallbacks
+
+- Don't add try/catch for "internal" errors. Trust your own code.
+- Don't validate things the type system already proves.
+- Boundary code (user input, network, FS) does validate; everything
+  else trusts.
+- No "graceful fallback" silently masking bugs. Log + crash >
+  silent wrong output.
+
+### Tests
+
+- Test what's hard to verify by reading the code: invariants, edge
+  cases, regressions.
+- Don't test type signatures or that `function returns X` (the type
+  system does that).
+- Don't write tests just to bump coverage.
+
+### Git / commits
+
+- Imperative mood, scope tag, why-not-what. See recent `git log`
+  for the pattern (`feat(ui): …`, `fix(loop): …`, `chore(release):
+  …`).
+- One logical change per commit; refactors land separately from
+  features.
+- No `Co-Authored-By: Claude` trailer.
+
+## PR expectations
+
+- Branch off `main`. One logical change per PR.
+- `npm run verify` must pass locally (lint + typecheck + tests +
+  comment-policy gate). Pre-push hook runs this; CI runs it on
+  Node 20 and 22.
+- Update `CHANGELOG.md` under `## [Unreleased]` if user-visible.
+  Maintainers move it under a versioned section at release time.
+
+## Code review
+
+Reasonix prefers blunt, fast review. Expect:
+
+- Line-level pushback on comments that explain *what* instead of *why*.
+- Pushback on new abstractions / flags introduced before there are
+  two real call sites.
+- Pushback on hand-rolled implementations of problems a maintained
+  npm library already solves.
+
+None of this is personal — it's how the codebase stays small.
+
+## Releasing (maintainers)
+
+1. Bump `package.json` version.
+2. Move `## [Unreleased]` → `## [X.Y.Z] — <date>` in `CHANGELOG.md`.
+3. `chore(release): X.Y.Z — <one-line summary>` commit.
+4. `git tag -a vX.Y.Z -m "..."`, push commit + tag.
+5. Wait for CI green, then `npm publish`.
+
+## Reporting security issues
+
+Don't open a public issue. Email <359807859@qq.com> with details and
+a reproduction; we'll respond within a few days.

+
+## Why Reasonix? (vs Cursor / Claude Code / Cline / Aider)
+
+Three things you'd come to Reasonix for, that nothing else combines:
+
+- **Cost economics that land in your bill.** DeepSeek V4 is ~30×
+  cheaper than Claude Sonnet per token. Cheap tokens alone isn't the
+  win — *cheap tokens with a 90%+ prefix-cache hit* is. Reasonix's
+  loop is engineered around append-only prompt growth so the
+  cache-stable prefix survives every tool call. The benchmarks
+  section verifies this end-to-end: 90.2% live cache hit, versus
+  32.8% for a generic harness on the same workload. The `/stats`
+  panel surfaces "vs Claude Sonnet 4.6" savings on every turn.
+
+- **It lives in your terminal.** Pure CLI — no Electron, no VS Code
+  extension, no IDE plugin to wedge into your editor. Sits next to
+  git, tmux, and your shell history. macOS / Linux / Windows
+  (PowerShell, Git Bash, Windows Terminal all tested). The only
+  network call is to the DeepSeek API itself; no vendor server in
+  the middle.
+
+- **Open source and hackable, end to end.** MIT-licensed TypeScript.
+  The entire loop, tool registry, cache-stable prefix, TUI, MCP
+  bridge — all in `src/` under 30k lines. Fork it, ship a private
+  build, drop it into CI. No SaaS layer, no enterprise tier, no
+  feature gates.

+<summary><strong>When reasonix is the wrong choice · DeepSeek/Anthropic-compat caveats · vs Aider/Cline/Continue</strong></summary>
+
+### Pick something else when
+
+- **You want multi-provider flexibility** (mix Claude / GPT / Gemini /
+  local Llama in one tool). Try [Aider](https://aider.chat) or
+  [Cline](https://cline.bot). Reasonix is DeepSeek-only on purpose —
+  every layer (cache-first loop, R1 harvesting, JSON-mode tool repair,
+  reasoning-effort cap) is tuned against DeepSeek-specific behavior
+  and economics. Coupling to one backend is the feature, not a
+  limitation we'll grow out of.
+- **You want IDE integration** (inline diff in your gutter,
+  multi-cursor, ghost text, refactor previews). Try
+  [Cursor](https://cursor.com) or Claude Code's IDE mode. Reasonix
+  is terminal-first; the diff lives in `git diff`, the file tree
+  lives in `ls`, the chat lives in your shell.
+- **You're chasing the hardest reasoning benchmarks.** Claude Opus
+  4.6 still wins some leaderboards. DeepSeek V4-pro is competitive
+  on most coding tasks but doesn't lead every benchmark. If your
+  task is "solve this PhD-level proof" rather than "fix this auth
+  bug," start with Claude.
+- **You need fully-local / fully-free**. DeepSeek's API has free
+  credit on signup, but isn't free forever. For air-gapped or
+  always-free, look at Aider + Ollama or [Continue](https://continue.dev).
+
+### "But DeepSeek now has an Anthropic-compatible API — can't I just point Claude Code at it?"
+
+You can. DeepSeek ships an official Anthropic-compatible endpoint at
+`https://api.deepseek.com/anthropic`, and Claude Code (or any Anthropic
+SDK client) talks to it without modification. The protocol works. The
+**caching economics** don't transfer, and that's the whole point.
+
+Look at DeepSeek's [own compatibility table](https://api-docs.deepseek.com/guides/anthropic_api):
+
+| Field | Status on DeepSeek's compat endpoint |
+|---|---|
+| `cache_control` markers | **Ignored** |
+| `mcp_servers` (API-level) | Ignored |
+| `thinking.budget_tokens` | Ignored |
+| Images / documents / citations | Not supported |
+
+`cache_control: Ignored` is the load-bearing line. Two completely
+different cache mechanics are colliding here:
+
+| | Anthropic native | DeepSeek auto-cache |
+|---|---|---|
+| Model | **Marker-based.** You put `cache_control` on a message; Anthropic caches "everything up to this marker" as a content-addressed unit. Multiple markers = multiple independent breakpoints. | **Byte-stable prefix.** The cache fingerprints the literal byte stream from byte 0. |
+| Claude Code's design | Built around this. Markers on system prompt + tool defs let the loop reorder, compact, or insert metadata after the markers without losing the cache. | n/a — Claude Code wasn't designed for byte-stable prefixes. |
+| What happens when Claude Code → DeepSeek compat | Markers stripped (ignored). Claude Code's main caching strategy disappears. | Falls back to auto-cache. But Claude Code's prefix isn't byte-stable (markers were the *substitute* for byte-stability), so auto-cache misses too. |
+
+Net effect: **Claude Code's loop, redirected at DeepSeek, gets the
+cheap tokens and loses the cache hit it depended on.** A loop running
+at 80%+ cache hit on Anthropic's marker cache lands somewhere in the
+40-60% range on DeepSeek's auto-cache (matches the generic-harness
+baseline in our benchmarks). Same model, same API, same workload —
+the loop's invariants don't fit the cache mechanic it's now talking
+to.
+
+Reasonix's loop was designed around byte-stable prefix from line one.
+No markers, no breakpoints — append-only is the invariant. That's why
+the same τ-bench workload lands at **90.2% cache hit** on Reasonix
+and **32.8%** on a cache-hostile baseline (committed transcripts;
+benchmarks section below). At DeepSeek's pricing — $0.07/Mtok
+uncached, ~$0.014/Mtok cached — the difference between 50% and 94%
+hit is **roughly 2.5× on input cost alone**.
+
+### "What about Aider / Cline / Continue?"
+
+They support DeepSeek natively (no compat layer needed) and you do
+get the cheap token price. What you don't get is the DeepSeek-
+specific loop work — those tools' loops support every backend
+generically (OpenAI / Anthropic / local Llama / ...) and use
+compaction + summarization patterns that destroy byte-stability. They
+land in the same 40-60% cache-hit range as the baseline. Plus a
+handful of DeepSeek-specific quirks generic loops don't handle:
+
+| Generic loops assume | DeepSeek actually does | Reasonix's fix |
+|---|---|---|
+| Reasoning emitted as a structured `thinking` block | R1 sometimes leaks tool-call JSON inside `<think>` tags | a `scavenge` pass that pulls escaped tool calls back out, otherwise the model thinks it called and waits for output that never comes |
+| Tool schemas validated strictly | DeepSeek silently drops deeply-nested object/array params | auto-flatten — nested params get rewritten to single-level prefixed names so the model sees them at all |
+| Tool-call args are well-formed JSON | DeepSeek occasionally produces `string="false"` and other malformed fragments | dedicated `ToolCallRepair` heals the common shapes before they hit dispatch |
+| Reasoning depth tuned via system-level switches | V4 exposes a `reasoning_effort` knob (`max` / `high`) | `/effort` slash + `--effort` flag, so users can step down for cheap turns |
+| Old tool results kept in full forever | 1M context — don't compact pre-emptively, but most agents do | call-storm breaker + result token cap, but the prefix is *never* rewritten; compaction lands as new turns at the tail |
+
+> Cache-stability isn't a feature you turn on; it's an invariant
+> the loop is designed around. Reasonix isn't yet-another agent
+> CLI — it's an agent CLI built around DeepSeek's specific cache
+> mechanic and pricing model.

+**1. 获取 DeepSeek API Key。** 注册即送免费额度：
+<https://platform.deepseek.com/api_keys>
+
+**2. 切到项目目录运行。** 无需安装。
+
+```bash
+cd my-project
+npx reasonix code

+
+首次运行会走 30 秒向导（粘贴 API key → 选预设 → 多选 MCP 服务器）。
+之后每次直接进入。
+
+**3. 让它改代码。** 模型会以 SEARCH/REPLACE 块的形式提出编辑——
+你不 `/apply`，磁盘不会被改。

+
+---
+
+## 为什么选 Reasonix？（vs Cursor / Claude Code / Cline / Aider）
+
+三件事，别家不会同时都给你：
+
+- **成本节省落到账单上。** DeepSeek V4 的 token 单价大约是 Claude Sonnet
+  的 1/30。光便宜还不够 —— *便宜的 token 配上 90%+ 的前缀缓存命中*才是关键。
+  Reasonix 的循环按 append-only 增长设计，缓存稳定的前缀在每次工具调用之间
+  都活着，下面的 benchmark 章节端到端验证过：实测 90.2% 缓存命中，对照组通用
+  框架只有 32.8%。`/stats` 面板每轮都跟踪 "vs Claude Sonnet 4.6" 的节省额。
+
+- **它住在终端里。** 纯 CLI —— 没有 Electron，没有 VS Code 插件，没有要
+  塞进编辑器的 IDE 插件。和 git、tmux、shell 历史并排。macOS / Linux /
+  Windows（PowerShell、Git Bash、Windows Terminal 都测过）。唯一的网络
+  请求就是 DeepSeek API 本身，中间没有厂商服务器。
+
+- **开源且彻底可改。** MIT 许可的 TypeScript。整个循环、工具注册表、
+  缓存稳定前缀、TUI、MCP 桥接 —— 全部在 `src/` 下，不到 3 万行。Fork
+  它、做私有构建、塞进 CI 都可以。没有 SaaS 层，没有企业版，没有功能闸门。

+<details>
+<summary><strong>什么时候 reasonix 不适合 · DeepSeek/Anthropic-compat 细节 · vs Aider/Cline/Continue</strong></summary>
+
+### 这些情况下应该选别的
+
+- **你想要多模型混用**（在一个工具里同时切 Claude / GPT / Gemini / 本地 Llama）。
+  试试 [Aider](https://aider.chat) 或 [Cline](https://cline.bot)。Reasonix
+  故意只绑 DeepSeek —— 每一层（缓存优先循环、R1 harvest、JSON 模式的工具
+  调用修复、reasoning_effort 上限）都是为 DeepSeek 的具体行为和经济模型
+  调出来的。绑死后端是设计选择，不是早晚要解决的限制。
+- **你想要 IDE 集成**（编辑器侧边栏 inline diff、多光标、ghost text、重构
+  预览）。试试 [Cursor](https://cursor.com) 或 Claude Code 的 IDE 模式。
+  Reasonix 是终端优先的：diff 在 `git diff` 里、文件树在 `ls` 里、对话
+  在 shell 里。
+- **你在追最难的推理 benchmark**。Claude Opus 4.6 还是赢一些榜单的。
+  DeepSeek V4-pro 在大多数编程任务上都很有竞争力，但不是每个 benchmark
+  都领先。如果你的任务是"证明这个 PhD 级别的数学命题"而不是"修这个
+  auth bug"，从 Claude 起步更合适。
+- **你需要完全本地 / 永远免费**。DeepSeek API 注册送额度，但不是永久
+  免费。要真正离线/永久免费，看看 Aider + Ollama 或者
+  [Continue](https://continue.dev)。
+
+### "DeepSeek 现在有 Anthropic 兼容 API 了，我直接拿 Claude Code 接上不就行？"
+
+可以接。DeepSeek 官方提供了 Anthropic 兼容端点
+`https://api.deepseek.com/anthropic`，Claude Code（或任何 Anthropic SDK
+客户端）不改一行代码就能连上去。**协议跑得通，缓存经济学跑不通** ——
+而后者才是关键。
+
+看 [DeepSeek 自己的兼容性表](https://api-docs.deepseek.com/guides/anthropic_api)：
+
+| 字段 | 在 DeepSeek 兼容端点上的状态 |
+|---|---|
+| `cache_control` 标记 | **Ignored（被忽略）** |
+| `mcp_servers`（API 层）| Ignored |
+| `thinking.budget_tokens` | Ignored |
+| 图像 / 文档 / 引用 | 不支持 |
+
+`cache_control: Ignored` 就是杀手级的那一行。这里有**两套完全不同的缓存
+机制在打架**：
+
+| | Anthropic 原生 | DeepSeek 自动缓存 |
+|---|---|---|
+| 模型 | **Marker 驱动。** 你在某条消息上打 `cache_control`，Anthropic 把"到此 marker 为止"的内容做内容寻址缓存。多个 marker = 多个独立断点。 | **Byte-stable prefix。** 缓存对字面字节流从第 0 字节起做指纹。 |
+| Claude Code 的设计 | 围绕这个设计的。在 system prompt + tool 定义上插 marker，让 loop 在 marker 之后做重排、压缩、插元数据都不丢缓存。 | n/a —— Claude Code 不是为 byte-stable prefix 设计的。 |
+| Claude Code 接 DeepSeek 兼容端点之后 | Marker 被 strip（忽略）。Claude Code 的主缓存策略消失。 | Fallback 到 auto-cache。但 Claude Code 的 prefix 不是 byte-stable 的（marker 本来就是 byte-stability 的*替代*），auto-cache 也命中不了。 |
+
+净效果：**Claude Code 的 loop 重定向到 DeepSeek 之后，便宜 token 拿到了，
+原本依赖的缓存命中没了**。一个在 Anthropic marker cache 上 80%+ 命中的
+loop，到 DeepSeek 的 auto-cache 上大概率掉到 40-60%（跟我们 benchmark 里
+通用 harness 的 baseline 同区间）。同一个模型、同一个 API、同一个负载 ——
+loop 的 invariant 跟它现在对话的缓存机制不匹配。
+
+Reasonix 的 loop 从第一行起就是按 byte-stable prefix 的不变量设计的。没有
+marker、没有断点 —— append-only 就是 invariant。这就是为什么同一份 τ-bench
+负载在 Reasonix 上是 **90.2% 缓存命中**、在 cache-hostile baseline 上是
+**32.8%**（已 commit 的 transcript，见下面 benchmark 段）。按 DeepSeek 的
+单价 —— $0.07/Mtok 非缓存、约 $0.014/Mtok 缓存命中 —— 33% 和 90% 命中之间
+**仅 input 这一侧就大约是 2.5× 的差距**。
+
+### "那 Aider / Cline / Continue 呢？"
+
+它们原生支持 DeepSeek（不需要兼容层），便宜 token 单价你确实拿到了。
+但你拿不到 DeepSeek-specific 的循环工程 —— 这些工具的 loop 是为**通用支持**
+所有后端（OpenAI / Anthropic / 本地 Llama / ...）设计的，用的是那种会破坏
+byte-stability 的通用压缩 / 摘要模式。命中率落在和 baseline 同样的 40-60%
+区间。再加上一堆 DeepSeek 怪癖通用 loop 不处理：
+
+| 通用 loop 假定 | DeepSeek 实际行为 | Reasonix 怎么处理 |
+|---|---|---|
+| 推理通过结构化 `thinking` 块产出 | R1 偶尔把 tool-call JSON 漏到 `<think>` 标签里 | `scavenge` 扫描把漏出的 tool call 拣回，否则模型以为自己已经调用，等不到结果 |
+| tool schema 严格校验 | DeepSeek 静默丢弃深嵌套 object/array 参数 | auto-flatten：嵌套参数被重写成单层 prefixed name，模型才看得见 |
+| tool-call args 是良构 JSON | DeepSeek 偶发 `string="false"` 之类的破碎片段 | 专用 `ToolCallRepair` 在 dispatch 之前修好常见形状 |
+| 推理深度靠系统级开关 | V4 直接暴露 `reasoning_effort` 旋钮（`max` / `high`） | `/effort` slash + `--effort` flag，简单任务可以降到 high 省钱 |
+| 老 tool result 永久保留 | 1M context 不需要主动 compact，但通用工具都会做 | call-storm breaker + 结果 token cap，但前缀**永不重写** —— 压缩作为新 turn 追加在尾部 |
+
+> 缓存稳定性不是一个开关，是 loop 设计之初就要建立的不变量。Reasonix
+> 不是"又一个 agent CLI"，是**围绕 DeepSeek 具体的缓存机制和定价模型
+> 设计的 agent CLI**。
+
+</details>
+

+
+## `reasonix code` — 终端里的结对编程
+
+作用域为启动目录。模型自带 `read_file` / `write_file` / `edit_file` /
+`list_directory` / `search_files` / `directory_tree` / `get_file_info` /
+`create_directory` / `move_file`，全部在沙箱内 —— 任何解析后落到启动根目录之外
+的路径（包括 `..` 或符号链接逃逸）都会被拒绝。再加上带只读白名单的
+`run_command`；任何会修改状态的命令（`npm install`、`git commit` 等）都要走
+确认弹窗。
+
+### 流程演示：先看再改
+
+对于"这段代码做什么用？"这类问题，模型会用读取类工具，然后用散文回答 ——
+不会出 SEARCH/REPLACE 块、也不会写文件。只有你明确要求修改时它才动手：
+
+```
+reasonix code › 这个项目的路由是怎么组织的？
+assistant
+  ▸ tool<directory_tree> → (src/ tree, 47 entries)
+  ▸ tool<read_file> → (src/router.ts, 1.2 KB)
+  ▸ 路由分三层：顶层 AppRouter 注册 tab，每个 tab 用 React Router 的
+    nested routes 写子路径，最后 …
+```
+
+`edit_file` 的 SEARCH 块如果没有按字节精确匹配文件内容，编辑会被显式拒绝
+而不是模糊匹配。模型能看到错误并自行重试 —— 比起"静默改错"，"显式拒绝"
+是更安全的失败方式。
+
+### Plan 模式 —— 执行前先审阅
+
+任何比"改个 typo"更大的改动，模型会被引导先提交一份 markdown 计划。
+你会看到 **批准 / 重做 / 取消** 三选一：
+
+```
+reasonix code › 把 auth 从 JWT 迁移到 session cookies
+
+▸ plan submitted — awaiting your review
+────────────────────────────────────────
+## Summary
+Swap JWT middleware for session cookies, keep user table intact.
+
+## Files
+- src/auth/middleware.ts — replace `verifyJwt` with `readSession`
+- src/auth/session.ts — new file, in-memory store + signed cookie
+- src/routes/login.ts — return Set-Cookie instead of a token
+- tests/auth/*.test.ts — update fixtures
+
+## Risks
+- Existing logged-in users get logged out (no migration).
+- Session store is in-memory; restart clears sessions.
+────────────────────────────────────────
+  ▸ Approve and implement
+    Refine — explore more
+    Cancel
+```
+
+**强制启用** 用 `/plan` —— 进入显式只读阶段：模型必须先提交计划，否则任何
+编辑或非白名单 shell 调用都不会执行。适合那些你想先审一遍再让模型动手的
+高风险改动。`/plan off` 或在弹窗里选 Approve/Cancel 退出。
+
+### 输入前缀 —— `!cmd` 与 `@path`
+
+两个不需要斜杠的内联快捷方式：
+
+**`!<cmd>` —— 在沙箱里跑 shell 命令并把结果喂给模型。** 像 bash 一样在
+prompt 里直接打。输出既会进入可见日志，也会进入会话 —— 模型下一轮会基于它
+推理：
+
+```
+reasonix code › !git status --short
+▸ M src/users.ts
+▸ M src/users.test.ts
+
+reasonix code › 把这两个文件的改动说明一下
+assistant
+  ▸ tool<read_file> → src/users.ts, src/users.test.ts
+  ▸ …
+```
+
+无白名单门 —— 用户主动输入的 shell 命令就是显式同意。60 秒超时、32k 字符
+上限，会话恢复后依然保留。
+
+**`@path/to/file` —— 内联一个文件作为 "Referenced files"。** 输入 `@`
+弹出选择器（↑/↓ 切换、Tab/Enter 插入）。比让模型 `read_file` 后再问更省事：
+"@src/users.ts 这个文件做什么用？"。沙箱限定：仅相对路径、不允许 `..`、单
+文件 64KB 上限。最近用过的文件排在前面。
+
+### `/commit` —— 一步暂存 + 提交
+
+```
+reasonix code › /commit "fix: findByEmail case-insensitive"
+▸ git add -A && git commit -m "fix: findByEmail case-insensitive"
+  [main a1b2c3d] fix: findByEmail case-insensitive
+```
+
+### 一些值得试试的命令
+
+- `/tool 1` —— 打印最后一次工具调用的完整输出（当 400 字内联剪辑不够看时）。
+- `/think` —— 看上一轮模型的完整推理（思考模式：v4-flash / v4-pro / reasoner 别名）。
+- `/undo` —— 回滚上一批已应用的编辑。
+- `/new` —— 在同一目录开新会话，但不丢失旧会话文件。
+- `/effort high` —— 从默认 `max` agent 推理强度降一档，简单任务更省更快。
+- `npx reasonix code --preset pro` —— 整轮锁定 v4-pro，不再自动降级到
+  flash。如果想要 self-consistency 分支，加 `--branch 3` 跑三路投票。
+- `npx reasonix code src/` —— 更窄的沙箱（只有 `src/` 可写）。
+- `npx reasonix code --no-session` —— 临时会话，什么都不存。
+
+### `reasonix stats` —— 你到底省了多少？
+
+每次 `reasonix chat|code|run` 跑完都会往
+`~/.reasonix/usage.jsonl` 追加一条精简记录（token + 成本 + Claude Sonnet
+4.6 同负载下的等价价格）。`reasonix stats` 不带参数会把日志聚合成今日 /
+本周 / 本月 / 历史 四个窗口：
+
+```
+Reasonix usage — /Users/you/.reasonix/usage.jsonl
+
+            turns  cache hit    cost (USD)      vs Claude     saved
+----------------------------------------------------------------------
+today           8      95.1%     $0.004821        $0.1348      96.4%
+week           34      93.8%     $0.023104        $0.6081      96.2%

+all-time      342      94.0%     $0.210881        $5.8934      96.4%
+```
+
+隐私：日志里只有 token、成本和你自己取的 session 名。没有 prompt、没有
+completion、没有工具参数。`reasonix stats <transcript>` 仍兼容老用法
+（按文件出 assistant turn + tool call 摘要）。
+
+### 保持最新
+
+面板顶栏在 `Reasonix` 旁边显示当前版本（如
+`Reasonix 0.12.6 · v4-flash · AUTO · max …`，最后那个 `max` 是推理强度
+徽章 —— `/effort high` 可降一档）。后台每 24 小时静默查询一次 npm
+registry，发现新版会在同一行右侧显示黄色 `update: X.Y.Z`。不阻塞、不烦人，
+每天最多查一次，离线 / 防火墙下静默失败。
+
+```bash
+reasonix update             # 打印当前 vs 最新，并执行 `npm i -g reasonix@latest`
+reasonix update --dry-run   # 只打印计划，不实际安装
+```
+
+通过 `npx` 用？命令会识别这种情况并改为打印 cache 刷新提示 —— npx 在下次
+调用时会自动取最新版本。
+
+### 项目约定 —— `REASONIX.md`
+
+把 `REASONIX.md` 放到项目根目录，每次启动都会被钉进 system prompt。可提交
+的团队记忆 —— 房间约定、领域词表、模型老忘的事情：
+
+```bash
+cat > REASONIX.md <<'EOF'
+# Notes for Reasonix
+- Use snake_case for new Python modules; legacy camelCase modules keep their style.
+- `cargo check` is in the auto-run allowlist; full `cargo test` needs confirmation.
+- The `api/` dir mirrors `backend/` — keep schemas in sync.
+EOF
+```
+
+重启（或 `/new`）后生效；前缀每会话只哈希一次，让 DeepSeek 的缓存保持热。
+`/memory` 打印当前已钉的内容。`REASONIX_MEMORY=off` 在 CI / 离线复现时关闭
+所有记忆来源。
+
+### 用户记忆 —— `~/.reasonix/memory/`
+
+第二层 **私人按用户** 的记忆放在你的 home 目录。不像 `REASONIX.md` 会被
+提交，模型自己也能通过 `remember` 工具往里写。两个作用域：
+
+- `~/.reasonix/memory/global/` —— 跨项目（你的偏好、工具链）。
+- `~/.reasonix/memory/<project-hash>/` —— 限定一个 `reasonix code` 沙箱
+  根目录（决策、本地事实、按仓库的快捷方式）。
+
+每个作用域都维护一个总是加载的 `MEMORY.md` 索引（一行一条）+ 零或多个
+`<name>.md` 详情文件（按需通过 `recall_memory` 加载）。写入立刻生效；钉进
+system prompt 在下一次 `/new` 或重启时生效，以保证当前会话的缓存前缀稳定。
+
+```
+reasonix code › 我用 bun 而不是 npm，请以后都用 bun 跑构建
+
+assistant
+  ▸ tool<remember> → project/bun_build saved
+    "Build command on this machine is `bun run build`"
+```
+
+**斜杠**：`/memory` · `/memory list` · `/memory show <name>` ·
+`/memory forget <name>` · `/memory clear <scope> confirm`。
+**模型工具**：`remember(type, scope, name, description, content)` ·
+`forget(scope, name)` · `recall_memory(scope, name)`。
+
+项目作用域只在 `reasonix code` 里可用（需要真实的沙箱根来计算哈希）；纯
+`reasonix` 只有全局作用域。
+
+### Skills —— 用户自定义的 prompt 包
+
+Skill 就是你写在磁盘上的散文指令块。Reasonix 把它们的名字 + 一行描述钉
+进 system prompt；模型可以在合适时机自动调 `run_skill({name: "..."})`，
+你也可以打 `/skill <name> [args]` 手动触发。
+
+两个作用域，与用户记忆同样的布局：
+
+- `<project>/.reasonix/skills/` —— 按项目（提交进 git 给团队，或加入
+  `.gitignore` 做个人草稿）。
+- `~/.reasonix/skills/` —— 全局，到处可用。
+
+两种文件结构都行：`<name>/SKILL.md`（推荐 —— 可同时打包附带资源）或扁平
+`<name>.md`。

+▸ running skill: review
+assistant
+  ▸ tool<run_command> → git diff --cached
+  ▸ 3 改动，1 个需要回归测试 …
+```
+
+或者让模型自己挑 —— 因为 skill 名字 + 描述都在前缀里，问 "帮我看下未提交
+的改动有没有风险" 就会触发 `run_skill({name: "review"})`，不用你打斜杠。
+
+**斜杠**：`/skill`（列出） · `/skill show <name>` · `/skill <name>
+[args]`（把 body 作为用户轮注入）。
+
+**故意不绑死** 任何其他客户端的目录约定（`.claude/skills` 等等）——
+Reasonix 在对话层是模型无关的。任何 SKILL.md 都能用；body 是散文，所以
+为别的工具写的 skill 多半能直接用（Reasonix 工具名不同 —— `filesystem`
+/ `shell` / `web` —— 但模型读到指令后会挑我们的等价工具）。
+
+### Hooks —— 围绕工具调用与轮次自动化
+
+在 `.reasonix/`（项目或 `~/`）放一个 `settings.json`，Reasonix 会在
+循环里四个常见的点触发 shell 命令：工具运行前、工具返回后、prompt 到达
+模型前、轮次结束后。
+
+```json
+// <project>/.reasonix/settings.json   ← 可提交
+// ~/.reasonix/settings.json           ← 按用户
+{
+  "hooks": {
+    "PreToolUse":       [{ "match": "edit_file|write_file", "command": "bun scripts/guard.ts" }],
+    "PostToolUse":      [{ "match": "edit_file", "command": "biome format --write" }],
+    "UserPromptSubmit": [{ "command": "echo $(date +%s) >> ~/.reasonix/prompts.log" }],
+    "Stop":             [{ "command": "bun test --run", "timeout": 60000 }]
+  }
+}
+```
+
+每个 hook 都是 shell 命令。Reasonix 调用时通过 stdin 传一份 JSON 信封，
+描述事件：
+
+```json
+{ "event": "PreToolUse", "cwd": "/path/to/project",
+  "toolName": "edit_file", "toolArgs": { "path": "src/x.ts", "..." } }
+```
+
+退出码决定走向：
+
+- **0** —— 通过；循环正常继续
+- **2** —— 阻断（仅对 `PreToolUse` / `UserPromptSubmit` 生效）；hook 的
+  stderr 会作为合成工具结果让模型看到，或者整条 prompt 直接被丢弃
+- **其他** —— 警告；循环继续，stderr 渲染为黄色行内提示
+
+`match` 是对工具名的锚定正则；`*` 或省略匹配所有工具。项目 hook 先于全局
+hook 触发。默认超时：阻断类事件 5 秒，日志类事件 30 秒；可在每条 hook 里
+用 `timeout` 覆盖。
+
+**斜杠**：`/hooks`（列出当前生效的 hook）· `/hooks reload`（不丢会话从磁盘
+重读 `settings.json`）。
+
+### 在 TUI 里保持最新
+
+`/update` 在运行中的会话里会显示当前版本、最近一次后台 24h 检查取到的最新
+版本，以及实际安装命令。这条斜杠 **不会** 直接 spawn `npm install` ——
+stdio:inherit 进入正在跑的 Ink 渲染器会把显示搞乱。要真正升级请退出会话，
+在新 shell 里执行 `reasonix update`。
+
+---
+
+## `reasonix` —— 也能当通用聊天
+
+同一套 TUI，没有文件系统工具（除非你通过 MCP 主动接入）。适合起草、问答、
+schema 设计、架构讨论，或者驱动你自己的 MCP 服务器。会话按名字保存在
+`~/.reasonix/sessions/`。
+
+```bash
+npx reasonix                             # 用已保存配置 + 向导选过的 MCP
+npx reasonix --preset pro                # 整轮锁定 v4-pro（不自动降级）
+npx reasonix --session design            # 命名会话 — 之后 --session design 续聊
+```
+
+临时挂 MCP 服务器：
+
+```bash
+npx reasonix \
+  --mcp "fs=npx -y @modelcontextprotocol/server-filesystem /tmp/safe" \
+  --mcp "kb=https://mcp.example.com/sse"
+```
+
+MCP 工具走和原生工具一样的 Cache-First + 修复 + 上下文安全管线 —— 32k
+结果上限、实时进度通知渲染、自动重试。

+## 会话内命令
+
+<details>
+<summary><strong>斜杠命令清单</strong>（点击展开）</summary>

+| `/retry` | 截断并重发上一条消息（重新采样） |
+| `/exit` · `/quit` | 退出 |
+
+**模型**
+

+| `/models` | 列出 DeepSeek `/models` 端点的可用模型 |
+| `/harvest [on\|off]` | 切换 R1 plan-state 提取 |
+| `/branch <N\|off>` | 每轮跑 N 路并行采样，挑最佳（N ≥ 2） |
+| `/effort <high\|max>` | reasoning_effort 上限 —— `max` 是 agent 默认，`high` 更便宜更快 |
+| `/think` | 打印上一轮的完整 thinking-mode 推理 |
+
+**上下文与工具**
+
+| 命令 | 作用 |
+|---|---|
+| `/mcp` | 列出已挂载的 MCP 服务器及其 tool / resource / prompt |
+| `/resource [uri]` | 浏览 + 读取 MCP resource（无参 → 列 URI；`<uri>` → 拉取） |
+| `/prompt [name]` | 浏览 + 拉取 MCP prompt |
+| `/tool [N]` | 打印第 N 次工具调用的完整输出（1 = 最近） |

+| `/stats` | 跨会话成本仪表盘（today / week / month / all-time） |
+| `/keys` | 键盘快捷键 + 输入前缀（`!` / `@` / `/`）速查 |
+
+**记忆与 Skill**
+
+| 命令 | 作用 |
+|---|---|
+| `/memory` | 显示已钉记忆（REASONIX.md + ~/.reasonix/memory） |
+| `/memory list` · `show <name>` · `forget <name>` · `clear <scope> confirm` | 管理记忆库 |
+| `/skill` · `/skill list` | 列出已发现的 skill（项目 + 全局） |
+| `/skill show <name>` | 打印某个 skill 的 body |

+| `/forget` | 从磁盘删除当前会话 |
+| `/setup` | 重新配置（退出后跑 `reasonix setup`） |
+
+**只在 code 模式下** (`reasonix code`)
+
+| 命令 | 作用 |
+|---|---|
+| `/apply` | 把待应用的 SEARCH/REPLACE 块写入磁盘 |
+| `/discard` | 丢弃待应用的编辑块 |

+| `/apply-plan` | 强制批准当前待审计划 |
+
+**键盘**
+
+- `Enter` —— 提交
+- `Shift+Enter` / `Ctrl+J` —— 换行（多行粘贴也行；
+  `\` + Enter 是跨平台兜底）
+- `↑` / `↓` —— 空闲时翻 prompt 历史；在斜杠自动补全里上下选
+- `/foo` 前缀下按 `Tab` / `Enter` —— 接受高亮的建议
+- `Esc` —— 中断当前轮（停 API 调用、取消进行中的工具、拒绝待响应的 MCP 请求）
+- 确认弹窗里的 `y` / `n` —— 快捷接受 / 拒绝
+
+</details>
+
+---
+
+## 会话与安全网
+
+- 会话以 JSONL 形式保存在 `~/.reasonix/sessions/<name>.jsonl`（`reasonix
+  code` 按目录分）。每条消息都原子追加；`Ctrl+C` 不会丢上下文。
+- 工具结果每次调用最多 32k 字符。超大会话加载时自动自愈（缩小并重写文件）。
+- 每次出站 API 调用前会校验 `assistant.tool_calls` / `tool` 的配对，损坏的
+  会话不会一直 400。
+- 上下文仪表 50% 变黄、80% 变红并提示 `/compact`。接近 1M token 上限
+  （V4 flash + pro）会先尝试自动压缩，再退化为强制总结。
+- `reasonix code` 沙箱拒绝任何解析后落到启动目录之外的路径（含符号链接
+  逃逸和 `..` 穿越）。
+
+### 故障排查：重复行 / 鬼影渲染
+
+有些 Windows 终端（Git Bash / MINTTY / winpty 包装的 shell）没完整实现
+Ink 用的 ANSI cursor-up 转义。表现：spinner、流式预览、工具结果行不在原地
+覆盖刷新，反而在 scrollback 里印出多份。
+
+遇到了就用 plain 模式：
+
+```bash
+REASONIX_UI=plain npx reasonix code
+```
+
+Plain 模式抑制了实时 / 动画行，关掉了内部 tick 计时器。代价是失去流式预览
+和 spinner，但 scrollback 稳定。Windows Terminal、Windows Terminal 里的
+PowerShell 7、WezTerm 不需要这个开关。
+
+---
+
+## Web 搜索 —— 默认开
+
+模型一启动就有两个 web 工具：`web_search` 和 `web_fetch`。无 flag、无 API
+key、无注册。当你问到模型训练时没见过的事（新发布、最近事件、冷门 API），
+它会自己决定调 `web_search`；snippet 不够就跟一个 `web_fetch`。
+
+底层是 **Mojeek** 的公开搜索页 —— 独立 web 索引，bot 友好，无 cookie /
+session。冷门或非常新的查询覆盖率比 Google/Bing 薄一些，但脚本里很可靠。
+（DDG 是原始后端，但 2026 年开始上反机器人页。）
+
+**关掉**（离线 / 隐私 / CI）：
+
+```json
+// ~/.reasonix/config.json
+{ "apiKey": "sk-…", "search": false }
+```
+
+```bash
+REASONIX_SEARCH=off npx reasonix code
+```
+
+**接自己的**（Kagi、SearXNG、内部缓存）：实现 `WebSearchProvider` 接口
+然后自己调 `registerWebTools(registry, { provider })`，或通过 `--mcp`
+桥接已有的 MCP 搜索服务器。
+
+---
+
+## MCP —— 自带工具
+
+任意 [MCP](https://spec.modelcontextprotocol.io/) 服务器都能用。向导内置
+目录可选，或用 flag 直接挂：
+
+```bash
+# stdio（本地子进程）
+npx reasonix --mcp "fs=npx -y @modelcontextprotocol/server-filesystem /tmp/safe"
+
+# 同时挂多个
+npx reasonix \
+  --mcp "fs=npx -y @modelcontextprotocol/server-filesystem /tmp/safe" \
+  --mcp "demo=npx tsx examples/mcp-server-demo.ts"
+
+# HTTP+SSE（远程 / 托管）
+npx reasonix --mcp "kb=https://mcp.example.com/sse"
+```
+
+`reasonix mcp list` 显示精选目录。`reasonix mcp inspect <spec>` 不开聊天，
+直接连一次并打印服务器的 tool / resource / prompt。长任务的进度通知
+（2025-03-26 spec）会以进度条形式实时渲染在 spinner 里。
+
+支持的传输：**stdio**（本地命令）和 **HTTP+SSE**（远程，MCP 2024-11-05
+spec）。

+
+## 性能对比 —— 缓存命中率自己也能验证
+
+这里每个抽象都对应 DeepSeek 的一个具体特性 —— 极低 token 价、R1 推理轨
+迹、自动前缀缓存、JSON 模式。通用框架把这些机会全留在桌上。
+
+| | Reasonix 默认 | 通用框架 |
+|---|---|---|
+| 前缀稳定的循环（→ 85–95% 缓存命中） | 是 | 否（每轮重建 prompt） |
+| 自动展平深层 tool schema | 是 | 否（DeepSeek 会丢参数） |
+| 带 jitter 退避的 429/503 重试 | 是 | 否（要自己写回调） |
+| 抢救泄到 `<think>` 里的 tool call | 是 | 否 |
+| 同参数重复爆发熔断 | 是 | 否 |
+| 实时缓存命中 / 成本 / vs Claude 面板 | 是 | 否 |
+
+同一 τ-bench-lite 负载（8 个多轮工具调用任务 × 3 次重复 = 每边 48 次运行），
+实测 DeepSeek `deepseek-chat`，唯一变量是前缀稳定性：
+
+| 指标 | 基线（缓存敌对） | Reasonix | 差值 |
+|---|---:|---:|---:|
+| 缓存命中 | 32.8% | **90.2%** | +57.4 pp |
+| 单任务成本 | $0.000992 | $0.000593 | **−40%** |
+| 通过率 | 100% (24/24) | **100% (24/24)** | — |
+
+**无需消耗 API 额度即可复现：**
+
+```bash
+git clone https://github.com/esengine/reasonix.git && cd reasonix && npm install
+npx reasonix replay benchmarks/tau-bench/transcripts/t01_address_happy.reasonix.r1.jsonl
+npx reasonix diff \
+  benchmarks/tau-bench/transcripts/t01_address_happy.baseline.r1.jsonl \
+  benchmarks/tau-bench/transcripts/t01_address_happy.reasonix.r1.jsonl
+```
+
+提交进仓库的 JSONL 文件每轮带 `usage`、`cost`、`prefixHash`。Reasonix
+的前缀哈希在每次模型调用时都字节稳定；基线则每轮都变。缓存差距是从日志稳
+定性 **机械可推导** 的，不依赖于 prompt 写得不一样。
+
+完整 48 次运行报告：
+[`benchmarks/tau-bench/report.md`](./benchmarks/tau-bench/report.md)。
+用自己的 API key 复现：`npx tsx benchmarks/tau-bench/runner.ts --repeats 3`。
+
+MCP 参考运行（即使两个 MCP 子进程并发，整 5 轮也只有一个前缀哈希）：
+
+| 服务器 | 轮次 | 缓存命中 | 成本 | vs Claude |
+|---|---:|---:|---:|---:|
+| 内置 demo（`add` / `echo` / `get_time`） | 2 | **96.6%**（第 2 轮） | $0.000254 | −94.0% |
+| 官方 `server-filesystem` | 5 | **96.7%** | $0.001235 | −97.0% |
+| **两者并发** | 5 | **81.1%** | $0.001852 | −95.9% |
+
+---
+
+## Non-goals（明确不做）
+
+- **多 agent 编排 / 子 agent**（用 LangGraph）。
+- **工作流 DSL / DAG 调度 / 并行分支引擎** —— skill 是散文，模型靠正常的
+  tool-use 循环串起来。这样保住了单循环 + append-only + cache-first 三大
+  不变量。
+- **多供应商抽象**（用 LiteLLM）。Reasonix 故意只做 DeepSeek —— 每个支柱
+  （cache-first 循环、R1 抢救、tool-call 修复）都针对 DeepSeek 的具体行为
+  和经济性做了调优。绑死一家后端是特性。
+- **RAG / 向量库**（用 LlamaIndex）。
+- **Web UI / SaaS。**
+
+Reasonix 只做 DeepSeek，做到底。

+## Conventions
+
+- **Imports** — explicit `import type` for type-only imports (Biome `useImportType: warn`). Direct relative imports within project, no barrel re-exports.
+- **Exports** — named exports only; no `export default`. Entry: `src/index.ts`.
+- **Tests** — vitest `describe`/`it`/`expect`, no globals. Naming: `<module>.test.ts` flat in `tests/`.
+- **JSX** — `.tsx` for Ink components. `jsx: "react"` in tsconfig.
+- **TypeScript** — `strict`, `noUncheckedIndexedAccess`, `noImplicitOverride`. Tools accept `ToolCallContext` (abort signal).
+- **MCP** — All transports implement `McpTransport` interface. Tools registered via registry at startup.
+- **Changelog** — Keep a Changelog format. Semver.
+
+## Watch out for
+
+- **This IS Reasonix** — edits to `src/loop.ts`, `src/repair/`, `src/tools/`, `src/mcp/` affect every session. Test before publishing.
+- **SEARCH must match byte-for-byte** — the edit-gate in `src/code/edit-blocks.ts` enforces exact match. Trailing whitespace or wrong indent = mismatch.
+- **`dist/`** is generated by `tsup`. Never hand-edit.
+- **`.reasonix/semantic/`** is auto-generated vector index. Never hand-edit.
+- **`sessions/` and `.reasonix/sessions/`** are user-private, git-ignored (per `.gitignore`).

-### Branch-and-Select *(v0.0.5, opt-in, builds on Pillar 2)*
-
-**Why now.** DeepSeek is cheap enough that running N=3 R1 samples is still
-cheaper than a single Claude call. What was research luxury (self-consistency
-sampling) becomes a practical default.
-
-**How.** When `--branch N` (or `{ branch: N }` in code) is passed:
-
-1. The turn is forced non-streaming (N samples must complete before we can
-   compare).
-2. `runBranches` fires N `client.chat` calls in parallel, spreading
-   temperatures across `[0, 1]` to diversify reasoning paths.
-3. Each sample's `reasoning_content` is piped through Pillar 2's harvest.
-4. The default selector picks the sample with the fewest `uncertainties`;
-   ties are broken by shorter answer length (Occam).
-5. The loop emits a `branch_summary` alongside the winning `assistant_final`.

+### Pillar 4 — Cost Control *(v0.6)*
+
+**Problem.** Coding agents that default to the frontier model (v4-pro, ~12×
+flash cost) and accumulate full tool results in context are $150-$250/month
+for active users. Most turns don't need frontier reasoning; most sessions
+re-pay for tool results that were only useful once.
+
+**Solution.** Four complementary mechanisms, none of which require manual
+tuning in the common case:
+
+#### 4.1 Tiered defaults (flash-first)
+
+The three presets now trade only **model tier** and **reasoning effort**:
+
+| Preset | Model | Effort | Harvest | Branch | Cost |
+|---|---|---|---|---|---:|
+| `fast` | `v4-flash` | `high` | off | 1 | 1× |
+| `smart` (default) | `v4-flash` | `max` | off | 1 | ~1.5× |
+| `max` | `v4-pro` | `max` | off | 1 | ~12× |
+
+**Branching and harvest are never in a preset.** Both multiply cost and
+rarely pay back; `/branch N` and `/harvest on` are pure opt-ins. A user can
+run for weeks without ever touching them.
+
+All auxiliary calls — `forceSummaryAfterIterLimit`, subagent spawns,
+truncation repair retries — hard-code `v4-flash + effort=high` regardless
+of the user's preset. There's no reason to pay pro rates for "paraphrase
+these tool results into prose" or for an `explore` subagent's grep chain.
+
+#### 4.2 Turn-end auto-compaction
+
+Every tool result in the log exceeding `TURN_END_RESULT_CAP_TOKENS` (3000)
+is shrunk to that cap when a turn ends. The model had the full text for
+the turn that read it; subsequent turns see a compact summary and can
+re-read if needed. One extra `read_file` call is vastly cheaper than
+dragging 12KB through every future prompt.
+
+A proactive 40% context-ratio threshold runs the same shrink pre-emptively
+inside long multi-iter turns before the 80% emergency threshold fires.
+
+#### 4.3 `/pro` single-turn arming
+
+Users who predict a hard task type `/pro`; the **next** turn runs on
+`v4-pro`, then auto-disarms. No preset churn, no forgotten revert. Armed
+state is visible as a yellow `⇧ pro armed` pill in the header.
+
+#### 4.4 Failure-signal auto-escalation
+
+The loop counts visible "flash is struggling" events per turn:
+- `edit_file` / `write_file` SEARCH-not-found errors
+- ToolCallRepair fires (scavenge / truncation-fix / storm-break)
+
+Once the count hits `FAILURE_ESCALATION_THRESHOLD` (3), the **remainder of
+the current turn** runs on `v4-pro`. Announced via a yellow warning row —
+no silent cost surprises. Counter + escalation flag reset at every turn

+#### Cost transparency
+
+Per-turn and session cost are colored in the StatsPanel:
+- `turn $0.003` — green <$0.05, yellow $0.05–0.20, red ≥$0.20
+- `session $0.12` — same scale ×10

-## Roadmap
+Files kept small by design: the largest module under `cli/ui/` is 2K
+lines (App.tsx), every handler under `slash/handlers/` is ≤200 lines,
+every hook under `cli/ui/` is ≤310 lines. Adding a new slash command
+means editing one handler file and one registry line.
 
-- **v0.0.1** — Pillar 1 end-to-end, Pillar 3 complete, Ink TUI, τ-bench scaffold.
-- **v0.0.2** — First-run key prompt, saved to `~/.reasonix/config.json`.
-- **v0.0.3** — Pillar 2 MVP (opt-in harvest), retry layer, TextInput fix.
-- **v0.0.4** — Schema flatten auto-applied in ToolRegistry (closes Pillar 3).
-- **v0.0.5** — Self-consistency branching (`--branch N`) driven by Pillar 2
-  plan-state uncertainty count.
-- **v0.0.6** — Named session persistence (`--session <name>`), JSONL log
-  stored under `~/.reasonix/sessions/`, restored into the append-only log
-  on resume.
+## Design evolution
+
+- **v0.0.x** — Pillar 1 end-to-end, Pillar 3 complete, Ink TUI scaffold.
 - **v0.1** — τ-bench numbers published, streaming polish, transcript replay.
 - **v0.2** — Self-consistency / branch-budget sampling driven by plan state.
-- **v0.3** — MCP client, session persistence.
+- **v0.3** — MCP client (stdio + SSE), session persistence.
+- **v0.4.x** — `reasonix code` with SEARCH/REPLACE edits, review/auto
+  gate, background jobs, hooks.
+- **v0.5.x** — V4 model support, skills, memory, subagents, actionable
+  error messages.
+- **v0.6** *(current)* —
+  - **Pillar 4 cost control** (flash-first defaults, auto-compaction,
+    `/pro` one-shot, failure-triggered escalation, cost badges).
+  - `deepseek-chat` / `deepseek-reasoner` scheduled for deprecation —
+    all user-facing surfaces updated to `v4-flash` / `v4-pro`.
+  - `branch` + `harvest` removed from every preset; manual opt-in only.
+  - Shared prompt fragments (`TUI_FORMATTING_RULES`, `NEGATIVE_CLAIM_RULE`).
+  - UI refactor: App.tsx split into 6 hooks/components, slash.ts split
+    into 13 per-topic modules.
 
 ## Explicit non-goals
 
-- Multi-agent orchestration.
+- Multi-agent orchestration as a first-class concept (subagents are a
+  cost-reduction mechanism, not a coordination primitive).
 - RAG / vector retrieval.
-- Support for non-DeepSeek backends.
+- Support for non-DeepSeek backends (an OpenAI-compatible shim would
+  work today via `--model` override, but is not tested).
 - Web UI / SaaS.
+- Automatic cost escalation without user-visible announcement. Every
+  pro-tier model call is surfaced; silent escalation was considered
+  and rejected.
