Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🔵 Low · up to The change prevents Doctor from recommending an unusable sync remedy for dangling config symlinks and preserves state without mutation.

In `@bench/journeys_issue_3557.go`:
- Around line 85-97: Update the Lstat assertions for the missing external target
and backup metadata to distinguish a nil error (path exists) from a real stat
error, reporting the observed path state when present and retaining the
underlying error details for other failures; apply the same handling to both
checks around issue-3557 validation.
In `@internal/cli/doctor_test.go`:
- Around line 355-372: Extract the repeated dangling-symlink fixture setup from
TestCheckStateJSON_AgentConfigDirDanglingSymlink and the other affected tests
into a shared danglingOpenCodeHome helper. Have it create the temporary home,
.config and .gentle-ai directories, symlink opencode to a missing target, write
the supplied state payload, preserve the symlink-unavailable skip behavior, and
return the home, config, and missing-target paths; update all four tests to use
it.
- Around line 997-1005: Remove the locally constructed preFixRemedy and its
assertion from the test block. Keep only the os.Stat observation needed to
verify that the dangling config path returns os.IsNotExist(err), allowing the
test’s production checkStateJSON path to detect regressions without duplicating
remedy text.
In `@internal/cli/doctor.go`:
- Around line 410-426: Update the managed config path scan around
InstalledAgents to collect non-ENOENT Lstat failures in an unreadable bucket
instead of silently continuing, while preserving missing and dangling
classification. Include unreadable paths in the Doctor warning branches and
their warning detail so errors such as EACCES, ELOOP, and ENOTDIR are reported.

CI status is narrowed to one base-suite blocker outside #3557. The final #3561 candidate at The remaining Unit Tests failure was: Root-cause update: subsequent clean-main and history audit showed this is not the closed #2181 classification defect. It is a distinct terminal-burn convergence regression introduced by #3417 / PR #3536, where a late FINALIZE can recreate burned lineage state. The canonical tracker is #3572, and the isolated fix is PR #3576. #3576 now has all required checks green and no unresolved review threads. No #3557 path touches the review/finalize subsystem, so #3561 should remain unchanged. After a human merges #3576, #3561 can be rerun or refreshed against the corrected base. Additional retry commits on #3561 would only add noise. |

#3561 is now refreshed from current main on head #3576 was superseded by #3587 after FINALIZE/journal closure was removed; its former dependency is deleted from this PR body. The only source conflict was the benchmark manifest. The #3557 journey is now the current free ID Focused Doctor/CLI tests, Doctor package tests, full bench tests, gofmt, and diff checks pass. The exact driven journey completed with 0 unsupported/failed results. Evidence JSON SHA-256: Hosted checks are running now. Once green, this PR is ready for fresh maintainer review as an independent #3557 work unit. |

Requesting changes. Only the final managed path is Lstated, so a dangling ancestor such as $HOME/.config pointing to a missing target produces ENOENT for its child and incorrectly enables RemedySync. Inspect path components and ancestors rather than only the final path. Add both a unit regression and a driven journey for the dangling-ancestor case; the remaining readiness evidence is otherwise verified.
A managed config path whose ancestor (e.g. ~/.config) is a dangling symlink Lstats as ENOENT and was classified as missing, wrongly enabling the sync remedy that cannot restore a path behind a broken link. When the final path is absent, walk its ancestors below the home directory: an existing ancestor symlink with a missing target now classifies the path as dangling, ancestor inspection errors reuse the unreadable treatment, and genuinely absent chains keep the sync remedy.
j118-doctor-dangling-config-ancestor replaces the sandbox ~/.config directory with a symlink to a missing target and proves the doctor names the dangling ancestor, never recommends sync, and leaves the symlink, its target, state.json, and the backups path untouched.

Dangling-ancestor gap is closed: the ancestor walk stays below $HOME, suppresses RemedySync only for a genuinely dangling ancestor symlink, and the two guards prove absent chains and healthy symlink ancestors still recommend sync. Driven proof on the real binary for j117 and j118, full suite and cross-platform vet green. Merging.
