Feature: Project context depth-gradient flag (B2.cli)
  As a CleverAgents user
  I want to set per-hop depth gradients via ``project context set --depth-gradient``
  So that context detail depth degrades with graph distance from focus nodes

  Background:
    Given a project context CLI in-memory database is initialized
    And a project "local/ctx-app" exists for context CLI

  # ── single depth-gradient value ─────────────────────────────

  Scenario: Set a single depth-gradient with integer value
    When I run context set on "local/ctx-app" with depth-gradient "0:9"
    Then the context set command should succeed
    And the stored ACMS depth gradient should have hop "0" with value 9

  Scenario: Set a single depth-gradient with named level value
    When I run context set on "local/ctx-app" with depth-gradient "1:SIGNATURES"
    Then the context set command should succeed
    And the stored ACMS depth gradient should have hop "1" with string value "SIGNATURES"

  # ── multiple depth-gradient values ──────────────────────────

  Scenario: Set multiple depth-gradient values
    When I run context set on "local/ctx-app" with depth-gradients "0:9,1:4,2:MODULE_LISTING"
    Then the context set command should succeed
    And the stored ACMS depth gradient should have hop "0" with value 9
    And the stored ACMS depth gradient should have hop "1" with value 4
    And the stored ACMS depth gradient should have hop "2" with string value "MODULE_LISTING"

  # ── invalid format ──────────────────────────────────────────

  Scenario: Invalid depth-gradient missing colon fails
    When I run context set on "local/ctx-app" with depth-gradient "bad"
    Then the context set command should fail

  Scenario: Invalid depth-gradient non-integer hop fails
    When I run context set on "local/ctx-app" with depth-gradient "abc:5"
    Then the context set command should fail

  # ── display in show command ─────────────────────────────────

  Scenario: Depth gradient is displayed in context show output
    Given I have set depth-gradient "0:9,1:SIGNATURES" on "local/ctx-app"
    When I run context show on "local/ctx-app" without options
    Then the context show command should succeed
    And the context show output should contain "Depth gradient"
    And the context show output should contain "0:9"
    And the context show output should contain "1:SIGNATURES"
