Feature: Project context CLI coverage boost
  Additional Behave scenarios targeting uncovered lines in
  src/cleveragents/cli/commands/project_context.py.

  Background:
    Given a coverage-boost in-memory database is initialized
    And a project "local/cov-app" exists for coverage boost

  # --- _load_policy_json returns None (line 106) ---
  # --- _read_policy returns default when raw is None (line 145) ---
  # --- _read_acms_config returns defaults when raw is None (line 164) ---
  Scenario: Reading policy from a fresh project returns defaults
    When I read the stored policy for "local/cov-app"
    Then the policy should be a fresh default policy
    And the ACMS config should equal the defaults

  # --- _write_policy preserves existing ACMS config (lines 199-201) ---
  Scenario: Writing policy without acms_config preserves existing ACMS config
    Given I seed ACMS config for "local/cov-app" with hot_max_tokens 9999
    When I write a policy for "local/cov-app" without explicit ACMS config
    Then the stored project-context ACMS config hot_max_tokens should be 9999

  # --- clear default view resets to empty ContextView (line 574) ---
  Scenario: Clearing the default view resets it
    When I run coverage-boost context set on "local/cov-app" with view "default" and include-resource "keep-me"
    And I run coverage-boost context set on "local/cov-app" with view "default" and clear flag

  Scenario: Setting default_depth to a non-integer string keeps it as string
    When I run coverage-boost context set on "local/cov-app" with default_depth "deep"
    Then the coverage-boost command should succeed
    And the stored ACMS config default_depth should be "deep"

    Then the coverage-boost command should have exit code 1
    And the coverage-boost output should contain "Invalid view"

  # --- strategy_filter in context_inspect (lines 874-878) ---
  Scenario: Context inspect with strategy filter narrows fragments
    Given the tier service has fragments for "local/cov-app" with strategy metadata
    When I run coverage-boost context inspect on "local/cov-app" with strategy filter "tier_a"
    Then the coverage-boost command should succeed

  # --- focus filter in context_inspect (lines 882-885) ---
  Scenario: Context inspect with focus filter narrows fragments
    Given the tier service has fragments for "local/cov-app" with strategy metadata

    And the coverage-boost output should contain "execute"

  # --- temporal scope "recent" and "all" in simulate (lines 301, 303) ---
  Scenario: Simulate with temporal scope recent
    Given I seed ACMS config for "local/cov-app" with temporal_scope "recent"
    When I run coverage-boost context simulate on "local/cov-app" with defaults
    Then the coverage-boost command should succeed

  Scenario: Simulate with temporal scope all
    Given I seed ACMS config for "local/cov-app" with temporal_scope "all"
    When I run coverage-boost context simulate on "local/cov-app" with defaults
    Then the coverage-boost command should succeed

  # --- budget exceeded breaks loop (line 335), long content truncation (line 339),
  #     access_count > 0 relevance (line 344) ---
  Scenario: Simulate truncates fragments exceeding budget and handles long content
    Given the tier service has large fragments for "local/cov-app" exceeding budget
    When I run coverage-boost context simulate on "local/cov-app" with budget 100
    Then the coverage-boost command should succeed
    And the simulation should have fewer fragments than stored

  # --- simulate with fragments renders rich table (lines 1085-1101) ---
  Scenario: Simulate with fragments shows rich table output
    Given the tier service has fragments for "local/cov-app" with strategy metadata
    When I run coverage-boost context simulate on "local/cov-app" in rich format
    Then the coverage-boost command should succeed
    And the coverage-boost output should contain "Assembled Fragments"

    Given the tier service has fragments for "local/cov-app" with strategy metadata
    When I run coverage-boost context simulate on "local/cov-app" with focus "res:file-alpha"
    Then the coverage-boost command should succeed

  # --- simulate with strategy_hints (line 293, 361) ---
  Scenario: Simulate with strategy hints
    When I run coverage-boost context simulate on "local/cov-app" with strategy hints "bfs,dfs"
    Then the coverage-boost command should succeed

  # --- _save_policy_json commit() regression test (line 133) ---
  # Exercises _save_policy_json then reads back via a *real* separate
  # session (no _SafeSession) to prove data persists across session
  # boundaries.  If commit() were reverted to flush(), this test fails.
  Scenario: Policy saved with commit persists across separate sessions
    When I save a policy for "local/cov-app" via a real session factory and read it back via a separate session
    Then the policy read from the separate session should contain the saved data

  # --- context_set ACMS overrides for remaining fields (lines 589-622) ---

    When I run coverage-boost context set on "local/cov-app" with all ACMS overrides
    Then the coverage-boost command should succeed
    And the stored ACMS config should reflect all overrides

  # --- _save_policy_json rollback path (contextlib.suppress + re-raise) ---
  # Verifies that when commit() fails, the exception is re-raised and the
  # session is rolled back, releasing DB locks.
  Scenario: Save policy rollback re-raises after commit failure
    When I attempt to save a policy with a commit that will fail
    Then the original commit exception should be re-raised
    And the session should not be in a dirty state after the failure

  # --- _save_policy_json on nonexistent project (0 rows affected) ---
  Scenario: Save policy on nonexistent project row updates zero rows
    When I save a policy for a nonexistent project "local/no-such-project"
