Summary by CodeRabbit

  • New Features

    • Added safer recovery for deleted or incomplete Codex marketplace installations.
    • Forced reinstall and uninstall can recover missing marketplace roots and generation markers when safety checks pass.
    • Recovery preserves lock identity, rollback state, and retry progress across partial failures.
    • Refresh continues across targets with unsafe locks while reporting an aggregate error.
  • Bug Fixes

    • Improved protection against symlink replacement, lock changes, and uncertain registration states.
  • Documentation

    • Added guidance for forced recovery, lock validation, cleanup, rollback, and retry handling.

Walkthrough

The change adds marker-absent generation recovery with no-follow lock validation. Codex marketplace install, uninstall, rollback, cleanup, registration, and retry flows now track dangling recovery state and preserve generation fences.

Changes

Codex recovery

Layer / File(s) Summary
Marker-absent generation fencing
crates/cli/src/installation/generation.rs
Retirement tracks present or absent markers. Recovery validates lock identity and filesystem paths before and after checks. Rollback preserves absent-marker state.
Marketplace recovery transactions
crates/cli/src/installation/marketplace/mod.rs, crates/cli/src/installation/marketplace/state.rs
Forced Codex recovery handles dangling marketplaces, uncertain registration, incremental cleanup, retained generation fences, rollback convergence, and persisted retry state.
Recovery validation and documentation
crates/cli/tests/coverage/agents/plugin_install_tests.rs, crates/cli/tests/coverage/shared/install_generation_tests.rs, docs/nemo-relay-cli/plugin-installation.mdx
Tests cover lock safety, dangling recovery, rollback, registration, cleanup, retries, and symlink cases. Documentation describes forced recovery and manual remediation.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 177f3

Forced recovery appears mergeable, but lock-replacement failure behavior needs stronger regression coverage and the refresh documentation must accurately describe its fail-fast behavior.

No change is required for this test.

revalidate_missing_marker takes &self, and commit_replacement takes &mut self, so the mut binding is correct. Marker-absent retirement starts with changed = false, and Drop rolls back only when changed && !committed. The failed revalidation therefore does not trigger rollback, and commit_replacement does not change the filesystem state.

Extract the shared removal-and-verification block.

This block is functionally identical to lines 3012-3036 in converge_committed_dangling_recovery: run both removals, re-probe the host when either fails, and downgrade the failure when the probe proves the registration is already gone. Two copies of the same conservative reconciliation rule will drift, and both feed retry state that the other flow reads back.

Extract a helper that takes the two Option<String> removal errors and returns (host_plugin_removed, host_marketplace_removed) plus any probe error. Both call sites keep their own error wording.

Add a case where the surviving lock is replaced during recovery.

This test proves the marketplace-root recheck. No test covers the other half of revalidate_missing_marker: the lock identity changing between acquisition and the first mutation. That lock is the only fence for marker-absent recovery, so the identity recheck is the security-relevant assertion.

Extend MockSetupRunner to replace layout.generation_lock with a new file during snapshot, then assert the error mentions changed lock identity and that runner.commands() stays empty.

As per path instructions, "Tests should cover the behavior promised by the changed API surface, including error paths and cross-request isolation where relevant."

🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Assert the post-failure state for the replaced-lock case.

The test proves that revalidate_missing_marker reports changed identity. It does not prove that Relay changed nothing else. Add assertions that the marker is still absent and that the replacement lock file still holds the original bytes. The sibling tests at line 155 and line 172 already use that pattern, so this keeps the fail-closed guarantee under test.

💚 Proposed added assertions
     let error = retirement.revalidate_missing_marker().unwrap_err();
 
     assert!(error.contains("changed identity"), "{error}");
+    assert!(!marker.exists());
+    drop(retirement);
+    assert!(!marker.exists());

removing it. The corresponding command without `--force` does not change the
dangling state and tells you which forced command to run.

Correct the integrations refresh documentation.

refresh propagates prepare_integrations_for_refresh errors before entering its target loop. An unsafe surviving lock therefore aborts preflight, and remaining targets are not attempted. The aggregate error applies only after preflight succeeds. Update lines 243–246 to describe this fail-fast behavior.

Replace the "described above" references with in-page links.

Three places point the reader at the new section by position: line 277, line 433, and line 439. Positional references are not reliable for screen readers and break if the page is reordered. The new heading at line 110 already provides an anchor. Link to it instead.

If you add the links, run just docs-linkcheck in addition to just docs.
