📝 Walkthrough

Walkthrough

The change adds the lyona-update manager with release checking, verified application, backup listing, rollback, and privileged installation. It extends installer support for multiple privileged helpers, adds PolicyKit authorization, reuses backup machinery, and adds automated coverage and project records.

Changes

Lyona update management

Layer / File(s) Summary
Release discovery and status reporting
scripts/lyona-update
Adds configuration, provenance reading, stable or preview release resolution, cache handling, version ordering, and check output states.
Apply, backup, and rollback lifecycle
scripts/lyona-update
Adds checksum verification, unprivileged builds, installation orchestration, backup retention, backup listing, and rollback validation.
Privileged helper and policy boundary
scripts/lyona-update-root, config/polkit/com.lyona.update.policy
Adds trusted root-only installation and restore operations with ownership, path, checksum, and invoking-user validation.
Installation and reusable backup integration
scripts/dev-sync-install.sh, Makefile, tests/test-dev-sync-install.sh
Adds library sourcing for backup reuse and generalizes privileged-helper installation, verification, backup manifests, uninstall handling, and checks.
Automated validation and project records
tests/test-lyona-update.sh, CHANGELOG.md, TASKS.md, docs/*
Adds isolated tests for update and rollback behavior and records the completed UPDATE-002 work and updated Phase 6 documentation.

Priority: ➖ Normal — Schedule this update-manager change because it adds release checking, installation, rollback, backups, and privileged system updates across Lyona.

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

Merge Risk: 🟠 High · up to b3638

Update checks and release downloads do not work, while the privileged install and rollback paths can act on user-modified content as root. These issues should be fixed before merge.

Inline comments:
In `@docs/P6-UPDATE-OVERVIEW.md`:
- Around line 21-22: Update the sequencing statement in the document to record
UPDATE-002 as complete and identify UPDATE-003 as the next boundary, while
preserving the existing Phase 5 and UPDATE-001 history.

In `@docs/UPSTREAM-SYNC.md`:
- Around line 329-333: Update the UPDATE-002 status in docs/UPSTREAM-SYNC.md
wherever it appears in the status table and accompanying prose to indicate
completion, using TASKS.md and the existing lyona-update implementation as the
source of truth. Keep UPDATE-003 marked as not started.

In `@scripts/lyona-update`:
- Line 150: Replace the invalid curl option --die with --fail in fetch_url at
scripts/lyona-update lines 150-150 and in the release archive download within
cmd_apply at scripts/lyona-update lines 483-485.
- Around line 592-600: Update backup_live_install to write the backup version
into checkout.txt using the key consumed by backup_version_of, and update
backup_version_of to return unknown when the file exists but no non-empty
version value is found. Preserve the existing behavior for missing checkout.txt
and ensure backup listings and rollback results never expose a blank version.
- Around line 396-399: Update run_privileged so the pkexec fallback to sudo
occurs only when pkexec returns status 126 or 127; return all other nonzero
statuses unchanged to prevent failed helper operations from running twice.

In `@scripts/lyona-update-root`:
- Around line 107-110: Update scripts/lyona-update-root so the privileged update
path never executes the staged Makefile via the install-system call. Validate
staged inputs against root-trusted release provenance, then invoke a root-owned
installer or fixed allowlisted installation routine while preserving the
existing USER_HOME, OWNER, and XDG_STATE_HOME behavior.
- Around line 127-133: Harden the authorized restore-system extraction around
system_archive and the sha256sum check: validate every archive member against a
root-owned managed-path manifest, rejecting traversal, absolute or unmanaged
paths, symlinks/hard links, device nodes, and special permission bits before
running tar -C / -xpf. Ensure the manifest cannot be replaced by the
backup-directory owner, and preserve the existing checksum failure behavior
while preventing any unvalidated archive from being extracted as root.

In `@TASKS.md`:
- Around line 84-92: Update the bare-TTY rollback wording in CHANGELOG.md to
describe it as intended fallback behavior pending disposable-VM validation,
rather than claiming the scenario is already confirmed to work. Keep the
existing implementation details and other changelog content unchanged.
