The design docs gained §4.3 (lock --check) and a restructured §5, shifting
apply→§4.4, status→§4.5, exit codes→§4.6, cache commands→§4.7, and
parallelism/fetch/cache/locking→§5.2–§5.5. Many references still used the
old numbering. This aligns everything with the current docs:

- Go comments (source + tests): §4.5→§4.6 exit codes, §4.6→§4.7 cache
  commands, §5.3→§5.1 apply flow, §5.4→§5.2 parallelism, §5.5→§5.3 fetch
  strategy, §5.6→§5.4 cache/store, §5.7→§5.5 project lock; checkSync's
  comment now lists the fields it actually compares (subdir, symlinks)
- design.zh-TW.md / design.md: §5.1 diagram cross-references (5.5→5.3),
  §4.1 cache row now lists `clean`, refreshed the last-updated date
- requirements.md: REQ-EXIT-NET §5.5→§5.3, REQ-PARALLEL-COLLECT and
  REQ-JOBS-FETCHDEFAULT §5.4→§5.2
- CLAUDE.md: §4.5→§4.6, Milestone 5 status (README already has CI
  examples), `make test` no longer claims -v
- READMEs: GRAFT_VERSION example uses a real released tag instead of
  v1.0.0; zh-TW README links the English design doc; normalized stray
  half-width punctuation in zh-TW prose

 A language-agnostic dependency manager for git repositories (Go, single binary) — a replacement for git submodules. Users declare deps in `graft.toml`, graft resolves them go.mod-style (tags or pseudo-versions) and pins exact commit SHAs plus content hashes in `graft.lock`; `graft apply` reconciles the vendor directory to match the lockfile exactly.
 
-**Current status: Milestones 1–4 implemented** — the full CLI (`init`/`add`/`remove`/`apply`/`lock`/`status`/`cache`), parallel apply, the per-project advisory lock, golden output tests, the release pipeline (`.goreleaser.yaml`, `install.sh`), and the global cache layer: the shared bare-repo cache (`internal/repocache`), the content-addressed store (`internal/store`, with reflink + `graft cache verify`/`prune`/`clean`), and link mode (`GRAFT_LINK_MODE`, registered in `internal/links`). Milestone 5 (ecosystem docs) is not implemented yet; the README marks that section as planned. The release pipeline is proven end-to-end (T3.4 done): `v0.0.1-beta.1` is published with multi-platform artifacts + `SHA256SUMS`. The project intentionally stays on a 0.x cadence (v0.0.1, v0.0.2, …) until it is very stable before cutting v1, so breaking changes are still permitted pre-1.0. Homebrew packaging is dropped for now — script install only. The source of truth is the design spec: the normative design (§1–§9) lives in the version-controlled `docs/design.zh-TW.md` (authoritative) with an English translation in `docs/design.md` — read it before implementing anything. Docs that must stay consistent with the spec: `docs/design.md` (English translation — keep in sync with the zh-TW doc), `docs/requirements.md` (the traceability matrix — see below), `docs/testing.md` (black-box testing manual), `README.md`, `README.zh-TW.md`. When changing behavior or design, update all of them.

Milestone 5 (ecosystem docs) is mostly done — the README already has CI usage examples (GitHub Actions, GitLab CI) and a comparison section; the documentation site remains unbuilt. The release pipeline is proven end-to-end (T3.4 done): `v0.0.1-beta.1` is published with multi-platform artifacts + `SHA256SUMS`. The project intentionally stays on a 0.x cadence (v0.0.1, v0.0.2, …) until it is very stable before cutting v1, so breaking changes are still permitted pre-1.0.

When changing behavior or design, update all of them.
 
 Spec ↔ implementation conformance is machine-enforced by two tests:
-- `internal/clierr/spec_test.go` binds the §4.5 exit-code table in both design docs to the `clierr` constants; it fails if spec and implementation (or the two translations) drift.
+- `internal/clierr/spec_test.go` binds the §4.6 exit-code table in both design docs to the `clierr` constants; it fails if spec and implementation (or the two translations) drift.
 - `internal/clierr/spec_coverage_test.go` parses `docs/requirements.md` (a flat table of `REQ-<AREA>-<TOKEN>` normative requirements) and scans `*_test.go` for `REQ-…` references (by convention in a `// spec: REQ-…` comment). It fails if any requirement has no covering test, or any test references an unknown ID. Adding a row to `requirements.md` therefore forces a covering test — this is the ratchet that drives spec coverage. The table currently covers the core install loop; remaining sections are filled in incrementally.

 **Content store。** 一個 store 條目就是某個鎖定檔 `hash` 對應的完整安裝樹：先簽出到 `tmp/`、計算雜湊、驗證，再原子 rename 到定位，所有檔案設為唯讀。因為鍵*就是* `graft.lock` 記錄的雜湊，store 命中不需要任何網路存取。兩個好處自然成立：`graft lock` 在計算雜湊的同時就填好了 store，接下來的 `graft apply` 安裝時完全不必重新下載；而完全相同的內容——即使來自不同的 repo 或版本——在每台機器上只儲存一份。

 - **copy**（預設）— 檔案系統支援時使用 copy-on-write reflink（APFS、btrfs、XFS、ReFS），否則一般複製。可觀察行為與沒有快取的 graft 完全相同，包括提交 `vendor/` 的工作流程，且 `apply` 每次執行仍照常重新驗證 vendor 樹的雜湊；安裝時從 store 具現化的樹在放進 vendor 前也會重新雜湊——損壞的 store 條目以結束碼 4 失敗並被移除（下次執行時重新擷取），永遠不會被安裝。
 - **symlink**（選擇性啟用：`GRAFT_LINK_MODE=symlink`）— `<dest>` 變成單一個指向 store 的目錄 symlink（Windows 上為 junction，不需要管理員權限），並登記到 `links/`。任意數量的專案共用同一份磁碟上的檔案樹。驗證簡化為低成本的連結目標比對：指向 `store/<鎖定雜湊>` 即為 `ok`，目標錯誤為 `modified`，連結懸空為 `missing`。限制：`vendor/` 必須加入 gitignore（提交一個連結對其他機器毫無意義），且 vendor 的完整性此時建立在 store 的不可變性上——檔案為唯讀，因此透過連結的意外編輯會立即失敗。同步時若發現 dest 以另一種模式具現化，視為偏移並以當前模式重寫。
