+- **Plan status JSON output wrapped in spec-required envelope** (#9450): The ``agents plan status --format json`` command now returns a spec-compliant JSON envelope with structured metadata fields (``command``, ``status``, ``exit_code``, ``timing.started``, ``data.progress``, ``data.execution.child_plans_with_suffix``, ``data.cost``) instead of a raw plan dictionary. Includes 20 BDD scenarios for full coverage.

The step definitions include self-contained symbol lookups to avoid cross-scenario dependency failures.

Includes ``TransactionSandbox`` infrastructure wired into ``SandboxFactory``, BDD test coverage in ``features/database_resources.feature``, and Robot Framework integration tests in ``robot/database_resources.robot`` (PR #10591 / issue #8608, Epic #8568).
 * HAL 9000 has contributed the agents plan rollback command (PR #8674 / issue #8557): implemented checkpoint-based plan state restoration with the `agents plan rollback <plan-id> [<checkpoint-id>]` CLI command as part of Epic #8493, enabling plans to be restored to previous checkpoints, discarding post-checkpoint decisions, and resuming execution from the rolled-back state. Supported by `--yes/-y`, `--to-checkpoint`, and `--format/-f` flags. Includes comprehensive BDD test coverage (>= 97%) for rollback, decision discarding, and plan resume functionality.

+Feature: Plan status --format JSON envelope compliance
+  As a CLI consumer
+  I want agents plan status --format json to produce a spec-compliant JSON envelope
+  So that downstream tools can reliably parse plan status output
+
+  Background:
+    Given a plan status JSON envelope CLI runner
+    And a plan status JSON envelope mocked lifecycle service
+
+  # ── Envelope structure tests ────────────────────────────────────────────────
+
+  Scenario Outline: Envelope has required top-level keys
+    Given a plan with phase <phase> and state <state>
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope should have key "command"
+    And the envelope command value should be "plan status"
+    And the envelope should have key "status"
+    And the envelope status value should be "ok"
+    And the envelope should have key "exit_code"
+    And the envelope exit_code value should be 0
+    And the envelope should have key "data"
+    And the envelope should have key "timing"
+    And the envelope should have key "messages"
+
+    Examples:
+      | phase      | state        | plan_id                      |
+      | strategize | queued       | 01KHDE6WWS2171PWW3GJEBXZ8S   |
+      | execute    | processing   | 01KHDE6WWS2171PWW3GJEBXZ8T   |
+      | apply      | complete     | 01KHDE6WWS2171PWW3GJEBXZ8U   |
+
+  # ── timing.started tests ───────────────────────────────────────────────────
+
+  Scenario: Timing.started includes plan created-at ISO timestamp
+    Given a plan with phase strategize and state queued
+    And the plan has no strategize_started_at timestamp
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope timing.started should be present
+    And the envelope timing.started should be an ISO-8601 timestamp
+
+  Scenario: Timing.started uses strategize_started_at when available
+    Given a plan with phase strategize and state processing
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope timing.started should be present
+    And the envelope data.timing.started should be the strategize start timestamp
+
+  Scenario: Timing.started defaults to created_at when no phase timestamps exist
+    Given a plan with phase action and state queued
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope timing.started should be present
+    And the envelope data.timing.started should be the plan created-at timestamp
+
+  # ── Data.action tests ──────────────────────────────────────────────────────
+
+  Scenario: Data.action field contains action name
+    Given a plan with name "local/test-plan" and action "local/code-coverage"
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.action should be "local/code-coverage"
+
+  Scenario: Data.action defaults to placeholder when missing
+    Given a plan with action field unset
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.action should start with "("
+
+  # ── Data.project tests ─────────────────────────────────────────────────────
+
+  Scenario: Data.project contains project link names
+    Given a plan linked to project "local/api-service" and "local/frontend"
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.project should contain "local/api-service"
+    And the envelope data.project should contain "local/frontend"
+
+  Scenario: Data.project is empty array when no project links
+    Given a plan with no project links
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.project should be an empty list
+
+  # ── Data.automation tests ──────────────────────────────────────────────────
+
+  Scenario: Data.automation contains profile name when set
+    Given a plan with automation profile "trusted"
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.automation should be "trusted"
+
+  Scenario: Data.automation is null when no profile set
+    Given a plan with no automation profile
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.automation should be null
+
+  # ── Data.attempt tests ─────────────────────────────────────────────────────
+
+  Scenario: Data.attempt is 1 by default
+    Given a plan with no automation profile
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.attempt should be 1
+
+  # ── Data.progress tests ────────────────────────────────────────────────────
+
+  Scenario: Data.progress has three steps (Strategize, Execute, Apply)
+    Given a plan with phase strategize and state queued
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.progress should have exactly 3 items
+
+  Scenario Outline: Progress status correctly shows queued/running/complete per action
+    Given a plan with phase <phase> and state <state>
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.progress.[<index>] action should be <action_name>
+    And the envelope should contain path "envelope.data.progress"
+
+    Examples:
+      | phase      | state        | index | action_name | 
+      | strategize | queued       | 0     | Strategize  |

+      | apply      | complete     | 2     | Apply       |
+
+  # ── DATA execution child_plans with "complete" suffix tests ────────────────
+
+  Scenario: Child plans format uses spec-required "complete" suffix
+    Given a plan with phase execute and state complete
+    And the plan has 3 subplan statuses
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.execution.child_plans_with_suffix should contain "complete"
+
+  # ── Timing.duration_ms tests ───────────────────────────────────────────────
+
+  Scenario: Envelope timing contains duration_ms key
+    Given a plan with phase strategize and state queued
+    When I run plan status for plan "<plan_id>" with format json
+    Then the envelope data.timing should have key "duration_ms"
