 ## Phase 1 — Core logic + navigation (done, initial version)
 
 - [x] `internal/kctl`: pure, unit-tested logic —
-      context-pair matching (`FindNextContext`) and namespace/label
-      filtering (`DistinctLabelValues`, `NamespacesForLabelValue`).
+      context-pair matching (`FindNextContext`), namespace/label filtering
+      (`DistinctLabelValues`, `NamespacesForLabelValue`), and secret diffing
+      (`DiffSecretValues`, `AnyMismatch`).
 - [x] `internal/config`: YAML config loading (`context_pairs`,
       `team_label_key`), with safe defaults when no config file exists yet.
 - [x] `internal/kubeexec`: thin wrappers around `kubectl`/`aws` CLI calls
-      (contexts, namespaces, deployments, rollout restart/status, secret
-      read, ExternalSecret annotation).
+      (contexts, namespaces, deployments, rollout restart/status, listing

 - [x] `cmd/kctl-tui` "full" mode: Bubble Tea navigation for
       context -> team -> namespace, with `Esc` correctly popping back one
       level at a time, defaults pre-selected from the currently active
       context/namespace.
 - [x] On confirming a namespace, "full" mode launches the 3-pane `tmux`
-      session (control pane + two `k9s` panes) via `tea.ExecProcess` and
-      resumes at the namespace screen once the session ends.
-- [x] `cmd/kctl-tui` "panel" mode: menu for Redeploy and the AWS/Kubernetes

-      session (`tmux kill-session`).

+      session ends.
+- [x] `cmd/kctl-tui` "panel" mode:
+      - Redeploy: pick a deployment from a list, confirm, then
+        `rollout restart` + `rollout status`.
+      - Secrets: pick an AWS region, then pick the actual secret from a
+        **list of all AWS Secrets Manager secrets** in that region (no more
+        manual secret-ID typing), enter the matching Kubernetes secret
+        name, and automatically diff **every field** of both secrets in one
+        table (key / AWS value / Kubernetes value / match status). If any
+        field differs, offer a single force-sync request for the **whole
+        secret** (one ExternalSecret annotation), not per individual field.

 ## Phase 2 — Hardening (open)
 
-- [ ] Replace the hand-rolled AWS secret JSON parsing/`fmt.Sprintf` value

-      plain strings rather than JSON.
+- [ ] Handle non-JSON AWS secrets and Kubernetes secrets with binary
+      (non-UTF8) values more gracefully in the diff table (currently
+      falls back to a single "value" key or may render oddly).
 - [ ] Add integration-style tests against a local `kind`/`k3d` cluster in
       CI for the `kubeexec` wrappers currently excluded from automated
       testing.
 - [ ] Input validation for the free-text steps in "panel" mode (empty
-      secret ID/region/name, invalid characters).
+      region/secret name, invalid characters).
 - [ ] Graceful handling when `tmux`, `k9s`, or `aws` are not installed

-      `kubectl` calls.
