mise dot track now reports each target's file count and size before confirmation, helping users catch large caches or session directories before saving an initial checkpoint. The tracking result also includes the count and size when confirmation is skipped.

mise dot track --dry-run ~/.codex
mise dot paths --preview ~/.codex

Both commands inspect the prospective capture without changing configuration or saving a checkpoint. paths --preview also lists files. Dry runs show exclusions, omitted files, nested repositories, and incomplete scans; long omission lists are summarized after twenty entries.

Trees over 5,000 files or 256 MiB produce a warning with guidance to exclude subdirectories or track individual files. These thresholds are advisory. Incomplete scans are reported before confirmation. Overlapping targets use the same ownership rules as capture, so a nested entry's files are not counted twice.

The preview performs a metadata scan without reading file contents and does not hold the declaration lock during a dry run. The actual baseline capture scans again after enrollment.

Validation: existing CI passed on the reviewed head. Unit and end-to-end coverage includes counts, sizes, overlapping entries, omissions, exclusions, and dry runs leaving configuration unchanged.

Documentation validation: scoped formatting/lint checks, TOML example parsing, and a full site build at the stack tip. The five focused dotfiles end-to-end tests passed locally.

Note

Medium Risk
Changes dotfile enrollment UX and filesystem walk behavior used by track/preview; mistakes could mis-size trees or skip paths, though dry-run avoids writes and actual capture still runs after enrollment.

Overview
Adds mise dot track --dry-run (-n) to walk prospective targets and print per-path file counts, total size, exclusions, omissions, nested repos, and incomplete scans without writing config or holding the declaration lock.

mise dot track now sizes each target the same way before confirmation: prompts and success logs include the summary, large trees (>5,000 files or 256 MiB) get an advisory warning, and overlapping targets use capture-style ownership so nested paths are not double-counted.

mise dot paths --preview shares the new preview_set / walk_selected plumbing and prints count and size in its header (still listing every file). Walk logic also counts symlink/nested-repo bytes correctly and skips re-walking subtrees owned by a more specific entry.

Docs, usage spec, man page, unit tests, and an e2e script cover dry-run, preview, exclusions, and --encrypt affecting the preview.

📝 Walkthrough

Walkthrough

The dotfile tracking commands now support dry-run previews. Previews report captured files, total size, omitted content, and large-tree warnings without writing tracking state. The paths preview uses the same capture calculation.

Changes

Dotfile tracking preview

Layer / File(s)	Summary
Preview sizing and tracked-set construction src/system/history/tracked.rs	Adds shared preview-set construction, file and byte aggregation, formatted summaries, omission handling, large-tree detection, and unit coverage.
CLI preview and tracking integration src/cli/dotfiles/track.rs, src/cli/dotfiles/paths.rs, mise.usage.kdl, man/man1/mise.1	Adds --dry-run, displays preview summaries and omissions, prevents writes during dry runs, includes summaries in prompts and logs, and uses the shared preview set for path previews.
Documentation and end-to-end validation docs/cli/..., docs/dotfiles.md, docs/history.md, e2e/cli/test_dotfiles_track_preview	Documents preview behavior, exclusions, and thresholds. The end-to-end test verifies preview output, omitted credentials, unchanged state, exclusions, and subsequent tracking.

Summary

Adds metadata-only previews for prospective dotfile tracking, including file counts, byte totals, exclusions, omissions, nested repositories, incomplete scans, and advisory large-tree warnings.

• Adds mise dot track --dry-run without configuration or checkpoint writes.
• Adds totals to tracking confirmation, completion output, and mise dot paths --preview.
• Preserves capture ownership for overlapping targets and prunes subtrees owned by nested entries.
• Extends nested-repository filtering to configuration sync and watcher scheduling.
• Adds focused unit, end-to-end, CLI, manual-page, and user-guide coverage.

Keep --dry-run free of declaration locking.

declaration_lock() creates the hashed cache lockfile for the .dotfiles-declarations.lock path. It also returns an error when another tracking command holds that lock. Acquire it only for the mutating branch.

let _declarations = if self.dry_run {
    None
} else {
    Some(declaration_lock()?)
};

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, hook-env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, ls on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, registry on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, startup on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143

Exclude nested repositories from byte totals.

The walker counts a nested repository as a captured path, but history stores it only as a gitlink. symlink_metadata(path).len() therefore adds directory metadata to the preview size, while captured content contributes zero bytes. Exclude nested repository paths from CaptureRoot::bytes and add a summary test.

🟡 Minor · Show active exclusions in mise dot paths --preview output. · paths.rs:45-96

src/cli/dotfiles/paths.rs:45-96
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Show active exclusions in mise dot paths --preview output. The preview omits excluded files from its count and file list, but the human-readable preview does not print tracked.exclude. This makes the documented “what is left out” preview incomplete. Print the exclusions in the preview branch, as mise dot track --dry-run already does.
