hasMarkerBlock previously swallowed every read/open error and returned
false, so an unreadable AGENTS.md (EACCES, EMFILE, EISDIR, ...) made
detectLegacyCodexSync report a clean Codex home instead of an
indeterminate inspection result. The fallback path could then skip
legacy cleanup and exit 0 with legacy artifacts still in place.
Restrict the catch to ENOENT (a missing file legitimately means no
marker block) and rethrow everything else. detectLegacyCodexSync
already propagates from hasMarkerBlock, so callers now see the actual
inspection error instead of a misleading 'no marker'.
Regression test in tests/lib/codex-legacy-sync.test.js makes a
detectLegacyCodexSync call against an unreadable AGENTS.md and asserts
that it throws something other than ENOENT, plus a sanity check that
a missing AGENTS.md still reads as no-marker.
Restrict the automatic `uninstall` legacy Codex sync fallback to homes
that have a legacy ownership manifest (`~/.codex/ecc/legacy-sync-state.json`).
Marker-only AGENTS.md files are no longer auto-detected as legacy installs,
so a normal `uninstall` will not silently modify user-owned instructions.
The explicit `--legacy-codex-sync` flag still handles marker-only and
manifest-backed cleanup.
Also:
- Track the AGENTS.md path in removedPaths when a marker block is removed.
- Refactor codex home resolution into a helper.
- Add regression tests for marker-only auto vs. explicit behavior.

Tighten uninstall auto-detection so it only falls back to the legacy
sync-ecc-to-codex.sh path when there is an ownership manifest
(~/.codex/ecc/legacy-sync-state.json) or an ECC marker block in
~/.codex/AGENTS.md. Previously a clean Codex home with unrelated prompt
files could be misclassified as a legacy install, causing uninstall to
skip normal install-state reconciliation and exit with a partial warning.
Also make the no-state fallback return 'not-found' when there is no
marker to remove and no candidate files to clean, and make explicit
--legacy-codex-sync report the same on a clean home.

Use no-follow file descriptors for legacy Codex snapshots, verification, restoration, and marker cleanup. Quarantine candidate removals and verify inode identity before deletion.
Carry the lifecycle runner as a verified artifact so privileged release workflows never dynamically check out and execute an output-selected revision.
