What it does

soar use switches by row id. switch_variant used to take a position in a list it queried a second time, so it could pick a different package if the rows changed in between. It now takes the variant's row id. list_variants also leaves out installs that never finished. Before this, the list offered such a row, and picking it failed after every real variant had already been unlinked. The half-finished install was left marked active and the user had no working variant. When only one variant is installed and it is unlinked, soar use now links it again instead of returning early. An id that does not fit the database's row id type is rejected instead of wrapping around to another row.

Broken symlink cleanup only removes links whose target is gone. A link counted as broken whenever exists() was false, which includes a target that is merely unreadable. Now a link is broken only when reading its target fails with "not found" or "not a directory", and each link is checked again right before removal. soar clean --broken-symlinks now uses this same code in soar-operations, which soar health already used. Before, soar clean ran an older copy in soar-core that also failed with "not a directory" when the desktop or icons directory did not exist. That copy is removed.

ghcr.io/ is recognised in any letter case. is_ghcr accepted Ghcr.io/..., but from_ghcr only stripped ghcr.io/ or GHCR.IO/, so a mixed-case reference installed with a family like Ghcr.io.pkgforge.soar. The stored reference now always starts with a lowercase ghcr.io/.

extract_root and nested_extract reject .. components, not the substring. Names like foo..bar are valid and were refused.

Also fixes a rustdoc error from #227: a public doc comment linked to the private PROGRESS_INTERVAL.

What it does not do

• Breaking API changes: switch::switch_variant(ctx, id) replaces switch_variant(ctx, name, index), and soar_core::utils::remove_broken_symlinks is removed.
• cargo doc on soar-cli still reports three errors that were already there. They are in files this PR does not touch.

Verification

Gate: fmt, clippy (stable and nightly), MSRV 1.93.1 check, cargo deny, and 654 workspace tests passing with 0 failures. cargo doc -D warnings is clean for soar-core and soar-operations.

New tests, each confirmed to fail with the old behaviour put back:

• switching_follows_the_row_id_and_skips_unfinished_installs: two installed variants with an unfinished install between them. It fails if unfinished installs are listed, if switch_variant accepts one, or if an id above the row id range wraps around to a real row.
• only_links_to_missing_targets_are_dangling: covers a regular file, a good link, a missing target, a target under a file, and an unreadable target. It fails against the old !exists() check.
• ghcr_prefix_is_case_insensitive: fails with either the old prefix strip or the old stored reference.
• extract_paths_reject_only_parent_components: fails with the old substring check.

Manual runs of the CLI against live repositories, old binary (current main) against new:

Case	Old	New
soar clean --broken-symlinks on a fresh root	Fails: applications dir is not a directory	"No broken symlinks found."
Link into an unreadable directory	Deleted	Kept
Dangling bin link and dangling *-soar.desktop	Not compared	Both removed; a non-soar desktop link is kept
soar use htop with an unfinished install row	Listed as option 3. Picking it errors and leaves both real variants unlinked	Not listed; switching between the two real variants works both ways
soar use htop with one installed variant, unlinked	Lists it and leaves it unlinked	Links it again
soar install Ghcr.io/pkgforge/bincache/tree/ppkg/tree:2.2.1-x86_64-linux	Family Ghcr.io.pkgforge.bincache.tree.ppkg.tree	Family pkgforge.bincache.tree.ppkg.tree, same as lowercase

Summary by CodeRabbit

• New Features

  • Cleaning now detects and removes dangling links more safely across supported application directories.
  • Variant switching now selects installed packages directly and excludes unfinished installations.
  • Inactive single variants can now be selected automatically.

• Bug Fixes

  • GHCR references accept mixed-case prefixes and are normalized consistently.
  • Valid names containing .. are accepted, while actual parent-directory paths remain blocked.
  • Variant switching validates selections and recreates links correctly.

📝 Walkthrough

The changes improve dangling-symlink cleanup, path validation, GHCR reference parsing, and installed-variant switching. The CLI now routes cleanup through the health operation. Progress documentation also changes its PROGRESS_INTERVAL reference.

Changes: Broken-symlink cleanup

Layer / File(s)	Summary
Dangling-link detection and removal crates/soar-operations/src/health.rs, crates/soar-core/src/utils.rs	Dangling-link checks distinguish missing targets from other metadata errors. Removal rechecks each candidate. The former core cleanup implementation was removed. Tests cover link classification.
Clean command integration crates/soar-cli/src/health.rs, crates/soar-cli/src/main.rs	The clean command calls the health operation with its context. The CLI reports removed paths or that it found no broken symlinks.

Package reference validation

Layer / File(s)	Summary
Relative path validation crates/soar-core/src/package/install.rs	Validation rejects parent-directory components instead of any path containing ... Tests cover accepted names, parent-directory paths, and absolute paths.
GHCR prefix parsing and normalization crates/soar-core/src/package/url.rs	GHCR prefix recognition and parsing accept any letter case. Parsed URLs use a lowercase ghcr.io/ prefix. Tests cover mixed-case and partial prefixes.

Installed-variant switching

Layer / File(s)	Summary
List and switch installed variants crates/soar-operations/src/switch.rs, crates/soar-cli/src/use.rs	Variant listing excludes unfinished installs. Switching looks up an installed package by row ID, and the CLI passes the selected package ID. Tests cover filtering, invalid selections, and switching an installed variant.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Allow selection of a sole unlinked variant.

If one installed variant is unlinked and another install is unfinished, list_variants now returns only the unlinked variant. This guard exits before switch_variant can restore its link. Return early only when the sole variant is already active.
