In @.config/ghostty/config:
- Around line 19-21: Update the Ghostty scrollback configuration to use
scrollback-limit-lines with a value of 1000 instead of the byte-based
scrollback-limit alias, preserving the adjacent iTerm2-equivalent setting.
In `@docs/machine-setup.md`:
- Around line 93-95: Update the restore instructions in the machine-setup
documentation to require stopping Claude Code before modifying any live state
under ~/.claude/ or ~/.claude.json, including merging history.jsonl; explicitly
instruct starting Claude Code only after the entire restore and merge completes.
- Around line 111-123: Update the collection flow documented near the repository
commands by adding an executable script that creates the migration root and
home/workspace directories, stores repository artifacts under git-extras/<repo>
with stashes in their designated subdirectory, generates unpushed-commits.txt,
and creates the final zip archive at the documented path. Ensure all existing
collection commands write directly to those final locations so the restore
commands can find them.
- Line 101: Update the directory tree code fence in the machine setup
documentation to specify the text language, using a text-tagged fence while
preserving the existing tree content.
- Line 11: Reorder the setup steps so GitHub SSH authentication is configured
before the git clone command, or replace the clone with an authentication method
available at that point. Ensure the dotfiles repository can be cloned on a new
Mac before proceeding to the later SSH key setup.
- Around line 136-141: Update the migration guidance in the “ハマりどころ（今回踏んだもの）”
section to require encrypting the archive or container before collecting
sensitive files, not only using an encrypted transfer path. Instruct users to
delete and verify removal of both the encrypted archive and extracted staging
directory after migration.
- Line 13: Update the setup instructions before the brew bundle install command
to initialize Homebrew in the current shell by adding the brew shellenv
evaluation to ~/.zprofile and evaluating it, then run brew bundle install.
- Around line 47-50: Update the Node setup instructions around nodenv install
and nodenv global to initialize nodenv with eval "$(nodenv init - zsh)" before
selecting or installing the Node version, then verify the active executable and
version using command -v node and node --version.
- Around line 27-29: Update the dotfile setup commands for nvim and ghostty to
be safely repeatable: remove or back up each existing destination before
copying, or clear the destination and copy the source contents so nested paths
and stale files cannot remain.
- Around line 129-130: Update the bundle import instructions after git bundle
verify so git fetch stores bundle heads under refs/remotes/migration/* instead
of directly under refs/heads/*. Keep the subsequent workflow explicit: inspect
the imported refs, then create or merge local branches as needed.

Ghostty configuration reference scrollback-limit unit bytes lines
💡 Result:
In Ghostty, you can control the scrollback buffer using two configuration options: scrollback-limit-bytes and scrollback-limit-lines [1][2]. 1. scrollback-limit-bytes: This setting defines the size of the scrollback buffer in bytes [3][4]. It accounts for both the active screen and the saved scrollback content [3][5]. It is important to note that the original configuration option scrollback-limit is still supported for backward compatibility and is treated as an alias for scrollback-limit-bytes [1][2]. 2. scrollback-limit-lines: This option allows you to limit the scrollback buffer by the number of lines instead of memory size [1][2]. These two settings are not mutually exclusive [1][2]. When both are configured, Ghostty applies the limit that is reached first [1][2]. Because lines are affected by viewport size and bytes are influenced by the contents (such as styles and graphemes), using both can be useful for managing memory and scroll history effectively [1][2]. The scrollback buffer is allocated lazily, meaning it does not immediately consume the full amount of memory specified [3][5]. These settings are applied per terminal surface rather than globally across the entire application [3][4], and changes typically only affect new terminal surfaces [3][4].

Homebrew official installation documentation brew shellenv Apple Silicon current shell
💡 Result:
To configure Homebrew on Apple Silicon, you must add the Homebrew directory to your shell's PATH by evaluating the output of the brew shellenv command [1][2]. On Apple Silicon Macs, Homebrew is installed to the default prefix /opt/homebrew [3][1]. Because this path is not included in your shell's default configuration, you must append the following command to your shell's configuration file (e.g., ~/.zprofile for zsh, which is the default shell on macOS) [1][4]: echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile After adding this line to your configuration file, you can apply the changes to your current shell session immediately by running: eval "$(/opt/homebrew/bin/brew shellenv)" The brew shellenv command ensures that Homebrew's bin and sbin directories are correctly added to your $PATH, $MANPATH, and $INFOPATH [2]. It also exports necessary variables like $HOMEBREW_PREFIX to prevent redundant lookups [2]. You can verify that Homebrew is correctly configured by running brew doctor, which will report any configuration issues [4].

macOS BSD cp -R source destination existing directory behavior recursive copy manual
💡 Result:
On macOS, the behavior of the cp command when performing a recursive copy (-r or -R) to an existing directory depends on whether the source path includes a trailing slash [1][2]. 1. Default Behavior (No Trailing Slash): If the source path does not end in a slash, the cp command copies the source directory itself into the destination directory [1][2]. This results in the source directory becoming a subdirectory of the destination (e.g., cp -r source/ dest/ becomes dest/source/...) [3]. 2. Copying Contents Only (With Trailing Slash): If the source path ends with a trailing slash (e.g., cp -r source/ dest/), the command copies only the contents of the source directory into the destination directory [1][2]. The source directory itself is not created within the destination [3]. Note that these behaviors are specific to how cp handles recursive directory structures [1][2]. If the destination directory does not exist, the cp command creates it and copies the source directory's contents into it, effectively renaming the directory during the copy process. [1][2]

site:manpagez.com macOS cp man page -R existing directory source destination
💡 Result:
On macOS, when the cp command is used and the final operand is an existing directory, cp treats that directory as the destination [1][2][3]. In this scenario, cp copies each specified source file into that directory [4][1]. The destination path for each copied file is constructed by appending the final component of the source file's name to the destination directory's path [5][3]. Key behaviors regarding this operation: - Target Directory Treatment: If the last operand is a directory, cp automatically treats it as a target directory, placing the source files inside it rather than overwriting the directory itself [2][3]. - Existing Files: For each destination file that already exists within the target directory, cp will overwrite its contents if permissions allow [1]. - Requirements: The target directory must exist for this behavior to occur [1]. If you provide only one source file and it is a directory, the command may behave differently depending on whether flags like -R (recursive) are used [1]. It is important to distinguish this from the behavior of cp when the destination is not an existing directory; in those cases, cp treats the destination as the name of the new file to be created [1][5].

nodenv official README shell initialization nodenv init zsh
💡 Result:
To initialize nodenv in Zsh, the recommended approach is to add the initialization command to your shell startup file, typically ~/.zshrc [1]. The official way to hook nodenv into your shell is by using the nodenv init command [2][3]. You can do this by adding the following line to your ~/.zshrc file [1]: eval "$(nodenv init - zsh)" This command operates in machine mode, outputting a shell script that is evaluated to configure your environment [2][3]. Specifically, it performs the following tasks: - Adds the nodenv executable to your PATH if necessary [2][3]. - Prepends the ~/.nodenv/shims directory to your PATH, which is the primary requirement for nodenv to function [2][3]. - Regenerates nodenv shims (you can use the --no-rehash flag if this slows down your shell startup) [2][3]. - Installs the shell dispatcher, which enables functionality like the nodenv shell command [2][3]. Note that while the nodenv init command handles most configuration, the Zsh completion script requires separate manual configuration to be discoverable by the shell [2][3]. You can enable it by adding the following to your ~/.zshrc (assuming nodenv is installed in /.nodenv) [2][3]: FPATH=/.nodenv/completions:"$FPATH" autoload -U compinit compinit If you prefer not to use the automated init helper, you can manually set these paths and completions in your shell initialization files [2][3].

Make the collection commands produce the documented archive tree.
Lines 118-122 write unpushed.bundle, stash-N.patch, and stash-list.txt in the current repository directory. The documented tree expects git-extras/<repo>/..., and no command creates unpushed-commits.txt, the stashes/ directory, the migration root, home/, workspace/, or the final zip. The restore commands therefore cannot reliably find the collected files. Add an executable collection script that writes each artifact to its final path and creates the archive.

Git fetch explicit refspec refs/heads current branch non-fast-forward update rules git-scm documentation
💡 Result:
When using an explicit refspec in git fetch, the refspec follows the format [+][]:[], where is the pattern for references on the remote and is the location where those references will be tracked locally [1]. Regarding non-fast-forward updates: - The optional leading plus sign (+) in the refspec acts as a force flag [1][2]. - Without this +, git fetch will refuse to update a local reference if the update is not a fast-forward [1][2]. - When an update is rejected, it is because the new tip being fetched is not a descendant of the existing local tip [1][2]. - You can override this check and force the update by including the + in the refspec or by using the --force command-line option [2][3][4]. - Even with --force, the refs/heads/* namespace will reject non-commit objects [2][3]. Regarding current branch behavior: - When git fetch is run with explicit refspecs on the command line (e.g., git fetch origin master), the command-line refspecs override the default remote..fetch configuration [5][6]. - If you provide a refspec such as master: (with an empty destination), Git interprets this as fetching the master branch without specifying a local remote-tracking branch to update [5][7][6]. - Explicitly fetching into your currently checked-out branch (i.e., a local branch in refs/heads/) is generally discouraged, as git fetch is designed to update remote-tracking branches (in refs/remotes/) [5][6]. Git purposefully refuses to update the head of the currently checked-out branch to prevent unexpected state changes, unless the --update-head-ok flag is used (which is intended for internal use by git pull, not general porcelain usage) [5][7][2]. For scenarios where you know a remote branch is rebased regularly (rewound), you should use the + prefix to allow non-fast-forward updates to your remote-tracking branches [2][3][8].

In `@docs/machine-setup.md` around lines 129 - 130, Update the bundle import
instructions after git bundle verify so git fetch stores bundle heads under
refs/remotes/migration/* instead of directly under refs/heads/*. Keep the
subsequent workflow explicit: inspect the imported refs, then create or merge
local branches as needed.

| ハマりどころ（今回踏んだもの）: | ||
|
|
||
| - **tracked かつローカル変更ありのファイル**を workspace/ に含めると、復元時のコピーで clone 直後の内容を上書きする。RESTORE.md に明示しておき、復元時に個別判断する | ||
| - 旧端末で checkout していた feature ブランチは、マージ後に remote から消えていることがある。未 push コミットが 0 なら消失はないので、RESTORE.md の一覧表で「未 push 数」を残しておくと復元時に切り分けられる | ||
| - zip には env ファイル等の機密が入る。**暗号化した経路で移送し、移行が終わったら旧端末側ともに削除する** | ||
| - venv / node_modules / ビルド成果物は入れない（README の手順で再生成） |

Protect the archive and staging directory.
“暗号化した経路” protects data in transit, not at rest. Require an encrypted archive or container before collecting sensitive files. Delete and verify removal of both the archive and the extracted staging directory after migration.

In `@docs/machine-setup.md` around lines 136 - 141, Update the migration guidance
in the “ハマりどころ（今回踏んだもの）” section to require encrypting the archive or container
before collecting sensitive files, not only using an encrypted transfer path.
Instruct users to delete and verify removal of both the encrypted archive and
extracted staging directory after migration.

概要
2026-08 の端末移行で実際に通した手順を、次回再現できる形で dotfiles に残す。
変更内容
.Brewfile一括インストール、dotfiles 配置、GitHub SSH / gh、nodenv / uv、gcloud（auth loginと ADC の2段階）、Claude Code（プラグイン・引き継ぎ対象・~/.claude.json差し替えの注意）git bundleによる未 push コミットの持ち出し、stash のパッチ書き出し、復元コマンド、今回踏んだハマりどころbrew leaves+ cask に合わせて更新（旧内容は go/node/tree のみで実態と乖離していた）備考
機密情報・業務固有の情報は含めていない（移行 zip の中でのみ扱う方針を手順書に明記）。
