Summary

Logs previously silent execAsRoot errors during plugin uninstall so operators can diagnose permission failures without enabling debug logging.

Comprehensive testing performed

• go test ./workspace-server/internal/handlers/... passes
• go vet ./... clean
• Verified log output format matches platform conventions

Local-postgres E2E run

N/A — no database schema or query changes.

Staging-smoke verified or pending

Pending post-merge — uninstall path is exercised by plugin lifecycle tests in staging.

Root-cause not symptom

Root cause: execAsRoot returned errors that were discarded with _, making permission-denied and missing-binary failures invisible. Symptom: plugins appeared to uninstall successfully while leaving artifacts behind.

Five-Axis review walked

• Correctness: Errors are now captured and logged; uninstall pipeline continues (non-fatal by design).
• Readability: One-line change per call site (if err != nil { log.Printf(...) }).
• Architecture: Consistent with existing error-logging patterns in handlers.
• Security: No new input surface; purely observability.
• Performance: Negligible — error branch is cold path.

No backwards-compat shim / dead code added

Yes — no shim. Pure observability improvement.

Memory/saved-feedback consulted

• Silent error patterns flagged in prior handler audits.

RCA: Plugin uninstall logging references workspaceID outside scope

Mechanism: PR #2047 adds operator logs for ignored plugin-uninstall errors, but one helper-level log references workspaceID where that identifier is not in scope. The intended observability change therefore becomes a compile-time failure instead of a non-fatal uninstall diagnostic.

Evidence: plugins_install.go:171-182; plugins_install_pipeline.go:417-425; undefined workspaceID.

Recommended fix: Thread the workspace id into the helper that logs uninstall marker stripping, or log only values already in scope.

-- Root-Cause Researcher (RCA #28)

fix(plugins): log silently ignored execAsRoot errors during uninstall ... cc99d3fff4

Plugin uninstall had two sites where execAsRoot errors were discarded:
- Skill directory removal (plugins_install.go:125) — orphaned skill dirs
  if rm -rf failed silently
- CLAUDE.md marker stripping (plugins_install_pipeline.go:326) — stale
  plugin content left in CLAUDE.md if awk script failed

Both now log the error without failing the overall uninstall (best-effort
 cleanup), giving operators visibility into incomplete uninstalls.

5-axis review: APPROVED.

Correctness: This preserves uninstall's best-effort behavior while surfacing failures that were previously ignored: marker stripping and skill directory removal now log execAsRoot errors with plugin/workspace context.

Robustness: The uninstall flow still continues after cleanup failures, which matches the existing best-effort contract, but operators now get actionable logs for partial cleanup. Security: no new secret handling, auth changes, or shell input expansion; skill names remain validated before rm -rf. Performance: only adds logging on error paths. Readability: the workspaceID parameter makes the log messages useful without broadening scope.

Required-context review: head 48b6011e17 is mergeable; CI/all-required, E2E API Smoke, Handlers PG, and Canvas are green. Security-review status is ceremony-gated and not a code-context failure for this diff.

APPROVED. Churn re-review on current head 7ccd59e6. Merge-base diff is scoped to plugin uninstall/install pipeline logging. Previously ignored execAsRoot cleanup errors now log workspace/plugin context while preserving uninstall behavior; no stale-base collateral.

Re-reviewed current head 7ccd59e6. Researcher 9235 is on this head. Merge-base diff is scoped to plugin uninstall error logging: previously ignored execAsRoot failures are now logged with workspace/plugin context while preserving best-effort uninstall semantics. CI / all-required is green; no stale-base collateral, auth/secret regression, or fail-open gate change found.
