+- **Manual automation profile respected during phase completion** (#4328): Fixed
+  ``complete_strategize()`` and ``complete_execute()`` in ``PlanLifecycleService`` to
+  gate ``auto_progress()`` calls with ``should_auto_progress()`` checks. Previously
+  these methods called ``auto_progress()`` unconditionally, causing plans with
+  ``--automation-profile "manual"`` (all thresholds=1.0) to auto-progress through
+  phases without human approval. Added BDD regression tests in
+  ``features/tdd_automation_profile_gates_4328.feature`` covering all 8 built-in
+  profiles.

 - **TUI Prompt Symbol Mode Awareness** (#6431): The prompt widget now displays a

   implemented via `_PromptSymbolMixin` and `InputMode.MULTILINE`. The widget uses

+Feature: Automation Profile Gates - Issue #4328 Regression Tests
+  Regression tests for manual automation profile being disrespected during phase
+  completion. Verifies that complete_strategize() and complete_execute() respect
+  automation profile gates and do NOT auto-progress when thresholds are 1.0.
+
+  Background:
+    Given I have a plan lifecycle service with automation level support
+
+  # ========================================================================
+  # Issue #4328: Manual profile (all thresholds = 1.0) should NOT auto-progress
+  # These scenarios verify the fix - that complete_strategize/execute do NOT
+  # unconditionally call auto_progress()
+  # ========================================================================
+
+  Scenario: Manual profile create_tool=1.0 blocks strategize to execute transition
+    Given I have a plan with automation level "manual" in strategize phase with processing state
+    When I complete strategize on the automated plan
+    Then the automated plan phase should be "strategize"
+    And the automated plan processing state should be "complete"
+    And should_auto_progress should return false
+
+  Scenario: Manual profile select_tool=1.0 blocks execute to apply transition
+    Given I have a plan with automation level "manual" in execute phase with processing state
+    When I complete execute on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "complete"
+    And should_auto_progress should return false
+
+  # ========================================================================
+  # Verify auto_progress() IS called when should_auto_progress() returns true
+  # ========================================================================
+
+  Scenario: Full-auto profile create_tool=0.0 allows strategize to execute auto-progress
+    Given I have a plan with automation level "full_automation" in strategize phase with processing state
+    When I complete strategize on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "queued"
+
+  Scenario: Full-auto profile select_tool=0.0 allows execute to apply auto-progress
+    Given I have a plan with automation level "full_automation" in execute phase with processing state
+    When I complete execute on the automated plan
+    Then the automated plan phase should be "apply"
+    And the automated plan processing state should be "applied"
+
+  # ========================================================================
+  # Supervised profile: create_tool=1.0 (blocks execute), select_tool=1.0 (blocks apply)
+  # ========================================================================
+
+  Scenario: Supervised profile create_tool=1.0 blocks strategize to execute auto-progress
+    Given I have a plan with automation level "supervised" in strategize phase with processing state
+    When I complete strategize on the automated plan
+    Then the automated plan phase should be "strategize"
+    And the automated plan processing state should be "complete"
+    And should_auto_progress should return false
+
+  Scenario: Supervised profile select_tool=1.0 blocks execute to apply transition
+    Given I have a plan with automation level "supervised" in execute phase with processing state
+    When I complete execute on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "complete"
+    And should_auto_progress should return false
+
+  # ========================================================================
+  # Review-before-apply (auto) profile: create_tool=0.0, select_tool=1.0
+  # ========================================================================
+
+  Scenario: Auto profile create_tool=0.0 allows strategize to execute auto-progress
+    Given I have a plan with automation level "review_before_apply" in strategize phase with processing state
+    When I complete strategize on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "queued"
+
+  Scenario: Auto profile select_tool=1.0 blocks execute to apply transition
+    Given I have a plan with automation level "review_before_apply" in execute phase with processing state
+    When I complete execute on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "complete"
+    And should_auto_progress should return false
+
+  # ========================================================================
+  # CI profile: all thresholds=0.0 (auto-progresses everything)
+  # ========================================================================
+
+  Scenario: CI profile blocks neither strategize nor execute transitions
+    Given I have a plan with automation level "ci" in strategize phase with processing state
+    When I complete strategize on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "queued"
+
+  Scenario: CI profile execute phase auto-progresses to apply
+    Given I have a plan with automation level "ci" in execute phase with processing state
+    When I complete execute on the automated plan
+    Then the automated plan phase should be "apply"
+    And the automated plan processing state should be "applied"
+
+  # ========================================================================
+  # Trusted profile: create_tool=0.0, select_tool=1.0 (same as auto for strategize/execute)
+  # ========================================================================
+
+  Scenario: Trusted profile allows strategize to execute auto-progress
+    Given I have a plan with automation level "trusted" in strategize phase with processing state
+    When I complete strategize on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "queued"
+
+  Scenario: Trusted profile select_tool=1.0 blocks execute to apply transition
+    Given I have a plan with automation level "trusted" in execute phase with processing state
+    When I complete execute on the automated plan
+    Then the automated plan phase should be "execute"
+    And the automated plan processing state should be "complete"
+    And should_auto_progress should return false
