Promote the Bootstrap's Kept Skills Tree to Main

[ptr727]

Promotes two changes. First, a bootstrap run that installs the skills now keeps its extracted tree, so the Claude Code plugin it registers no longer points at a directory the run deleted.

Refs #1756. It stays open until bootstrap.ps1 has a native Windows run.

Second, the registry now declares ESPHome-Config's Python as a build-profile uv workspace.

Closes #1762

What reaches main

• Kept tree: --host, --dev, and --skills (not under --dry-run) keep a bootstrap-owned skills-tree:
  • Under ${XDG_DATA_HOME:-~/.local/share}/host-setup on Linux, %LOCALAPPDATA%\host-setup on Windows, or --dir.
  • It is a plain extracted tarball, not a clone, and it never sits under ~/repos.
  • It carries .bootstrap-owned and .bootstrap-commit.
• Swap: the new tree is extracted to .new and takes the name immediately before the skills step. The old tree is moved aside first and removed last, and it is put back if a swap stops between the two renames. A stand-up that fails earlier leaves the plugin loading the previous tree.
• skills_install.py: reads a bootstrap tree's commit from its marker rather than git, for both the snapshot stamp and --report's live channel. A tree with no commit is an unjudgeable archive. It never replaces an existing registration.
• Windows loader: path cmdlets take -LiteralPath, and every rename in the rollback and cleanup is guarded.
• Docs: host-setup/README.md has a new "Where the Tree Lives" section, and docs/host-setup.md points to it.
• Registry (Declare ESPHome-Config's Python as a Build-Profile uv Workspace #1777): ESPHome-Config's profiles.python is now build, requiredSecrets lists CODECOV_TOKEN, and the driftNote describes the root uv workspace. That layout is on ESPHome-Config's develop and reaches its main with that repo's next promotion.

Review state

• Merge: merged to develop as 94fa3cb via Keep the Bootstrap's Skills Tree So the Claude Code Plugin Outlives the Run #1773, and as 2c5802f via Declare ESPHome-Config's Python as a Build-Profile uv Workspace #1777.
• Copilot: reviewed seven rounds, the last on the final head. Every thread is resolved, and every previously-missed finding is answered in the conversation: fixed, declined with evidence, or deferred to Bootstrap kept-tree rollback can leave no tree, and a hand-run report mislabels its commit #1770.
• CodeRabbit: rate-limited and posted no review.
• Declare ESPHome-Config's Python as a Build-Profile uv Workspace #1777: Copilot and CodeRabbit each raised the develop-versus-main timing of the ESPHome-Config entry, and both were declined per the maintainer's call. On head 2c5802f, Copilot raised two previously-missed findings about test coverage for the bootstrap swap and rollback, answered in the conversation and deferred to Bootstrap: no test executes the kept skills tree swap and rollback #1780.
• Local strict review: recorded passes over every pushed head. Their findings were fixed or filed as Two concurrent bootstrap runs can remove each other's tree #1764, install-skills.ps1 fails under a directory whose path contains a wildcard character #1765, Nothing tests the bootstrap loaders' kept-tree swap sequence #1767, Re-point a Claude Code registration an older bootstrap left dangling #1769, Bootstrap kept-tree rollback can leave no tree, and a hand-run report mislabels its commit #1770, The menu's skills task registers a clone it then removes #1771, and Two skills describe the live skills channel only as a git checkout #1772. The maintainer chose the kept-tree design over a clone, dropping re-pointing, and the review-loop stop point.

Summary by CodeRabbit

• New Features

  • Host, development, and skills installations now keep the extracted skills tree in place so the Claude Code plugin can load it. Subsequent installations replace the tree as part of the skills-install step; runs that fail before that step leave the previous tree available.
  • The retained tree is stored in the host-setup data directory by default, or under the directory provided with --dir.

• Documentation

  • Added guidance on where the tree is stored and when it is retained or removed, including behavior for other actions and dry runs.

📝 Walkthrough

Walkthrough

The Bash and PowerShell bootstrap scripts now retain extracted trees for skills-installing runs and replace them through staging and swap steps. The skills installer identifies bootstrap-owned trees and reads their commit metadata without querying Git.

Changes

Skills tree retention

Layer / File(s)	Summary
Tree paths and retention rules docs/host-setup.md, host-setup/README.md, host-setup/bootstrap.ps1, host-setup/bootstrap.sh, host-setup/menu.sh	The bootstrap scripts select data or cache paths based on the run mode, use skills-tree for retained trees, and check ownership markers. The documentation describes retained-tree locations and behavior.
Staging, swapping, and cleanup host-setup/bootstrap.ps1, host-setup/bootstrap.sh	Both scripts extract into owned staging directories, swap trees into place, restore retired trees when a swap stops midway, and apply cleanup rules based on the run mode.
Skills installation and tree metadata host-setup/bootstrap.ps1, host-setup/bootstrap.sh, scripts/skills_install.py, scripts/tests/test_skills_install.py	The bootstrap scripts swap retained trees in before skills installation. The installer recognizes bootstrap-owned trees and reads commit markers without Git queries. Tests cover marker and marketplace reporting cases.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 94fa3

The retained-tree change still has paths that can leave the plugin unavailable or report an incorrect skills revision. Resolve these issues before merging.

What changed in this PR

This pull request promotes the “kept bootstrap skills tree” design to main, ensuring the Claude Code marketplace registration points at a durable extracted tree instead of a temporary directory that gets deleted after the bootstrap run.

Changes:

• Teach scripts/skills_install.py (and its tests) to treat bootstrap-owned trees as archive sources and read their resolved commit from a marker file instead of querying git.
• Update the Linux and Windows bootstrap loaders to extract to a staging directory and swap a kept tree into place for skills-installing modes.
• Document where the kept tree lives and how it is swapped/retained.

File	Description
scripts/​tests/​test_skills_install.py	Adds coverage for bootstrap-owned marker handling and “never ask git” behavior.
scripts/​skills_install.py	Adds bootstrap markers, marker-based commit resolution, and live-channel reporting for bootstrap-owned trees.
host-setup/​README.md	Documents the kept tree location and swap behavior (“Where the Tree Lives”).
host-setup/​menu.sh	Adjusts comments to align with the updated ownership-marker framing.
host-setup/​bootstrap.sh	Implements kept-tree staging/swap/cleanup logic for skills-installing modes.
host-setup/​bootstrap.ps1	Implements kept-tree staging/swap/cleanup logic for skills-installing modes on Windows.
docs/​host-setup.md	Points readers to the kept-tree location documentation in host-setup/README.md.

Do not resolve an explicit revision in an enclosing repository.

When ROOT is bootstrap-owned, intended_commit(rev) must not call Git. git_in uses git -C ROOT, so Git can discover an enclosing repository and return its commit as the intended skills revision. Return (None, None) for an explicit revision that the archive cannot resolve.

         source = source_ref()

Answering CodeRabbit's outside-diff finding "Do not resolve an explicit revision in an enclosing repository" (scripts/skills_install.py:297-299): deferred to #1770, where it is already recorded. intended_commit(rev) asking git in a bootstrap tree predates #1773, and only a hand-run --report --intended reaches it, since the loaders never pass --intended. The suggested if rev and is_bootstrap_tree(ROOT): return None, None is the fix #1770 names.

Copilot review overview

🔵 Needs a closer look

The kept-tree swap/rollback sequence in both bootstrap loaders is complex but still lacks an automated test that executes and asserts its on-disk outcomes under simulated failures.

Review effort: Lite
Findings: None

Resolved since last review (1)

• Handle swap_in failures before registering the plugin

Previously missed (2)

In code that hasn't changed since last review

Lack of coverage for kept skills tree rollback flow

host-setup/​bootstrap.ps1:299

The swap/rollback behavior for the kept skills tree (staging .new, renaming to .old, rollback on failure, and cleanup behavior) is complex but is not covered by an automated test that executes these code paths. The current bootstrap tests are static invariants, so a reorder or regression in this sequence could pass CI while breaking the guarantee that failed runs leave the previously-registered tree intact.

Missing test for kept-tree swap and rollback behavior

host-setup/​bootstrap.sh:179

The kept-tree swap/rollback logic introduced here is not exercised by any automated test. scripts/tests/test_bootstrap.py asserts loader invariants and spec coverage, but nothing executes a run that stages to .new, swaps to .old, and verifies the on-disk tree left behind after simulated failures. This leaves the critical “plugin keeps loading the previous tree on failure” guarantee regression-prone.

[ptr727]

Answering Copilot's two previously-missed findings on head 2c5802f:

Lack of coverage for kept skills tree rollback flow (host-setup/bootstrap.ps1:299)

Missing test for kept-tree swap and rollback behavior (host-setup/bootstrap.sh:179)

Both are real and deferred to #1780, which asks for a test that runs the swap and rollback with failures injected at each step. The rollback defect itself is already tracked in #1770.
