## MODIFIED Requirements

### Requirement: Cloud Console displays a task's full LLM interaction history
Cloud Console SHALL provide a view, for a given task, listing each persisted planner decision in step order, including its full prompt, resulting decision, and — when available — the AI's rationale (pre-tool text reflection), thinking (extended thinking block), action purpose, and expected outcome, sourced from the Cloud Control Plane's persisted planner-decision log.

#### Scenario: Task has persisted planner decisions with rationale
- **WHEN** an operator opens the LLM interaction history view for a task that has one or more persisted planner decisions with non-null rationale
- **THEN** Cloud Console shows each decision in step order with its prompt, resulting tool call, and rationale text

#### Scenario: Task has persisted planner decisions with thinking
- **WHEN** an operator opens the LLM interaction history view for a task whose planner decisions include a non-null thinking field
- **THEN** Cloud Console shows the thinking content alongside the prompt and tool call for that step

#### Scenario: Task has persisted planner decisions without rationale or thinking
- **WHEN** an operator opens the LLM interaction history view for a task whose decisions have null rationale and null thinking
- **THEN** Cloud Console shows each decision without those fields, without error or placeholder text

#### Scenario: Task's Host used direct-to-provider transport
- **WHEN** an operator opens the LLM interaction history view for a task whose Host used direct-to-provider transport
- **THEN** Cloud Console indicates that no LLM interaction history is available because the Host does not report it, rather than showing an empty history with no explanation

### Requirement: Cloud Control Plane persists rationale and thinking in the planner decision log
The Cloud Control Plane's planner-decision log SHALL store the AI's rationale, thinking, action purpose, and expected outcome fields alongside the existing prompt and tool-call fields for each persisted decision. These fields SHALL be nullable for backward compatibility; absence of a legacy or non-AI value SHALL NOT prevent a decision record from being stored or queried.

#### Scenario: Decision record includes rationale
- **WHEN** the Host Agent reports a planner decision with a non-null rationale
- **THEN** the persisted `planner_decision_log` row stores that rationale text in the `rationale` column

#### Scenario: Decision record includes thinking
- **WHEN** the Host Agent reports a planner decision with a non-null thinking block
- **THEN** the persisted `planner_decision_log` row stores that thinking text in the `thinking` column

#### Scenario: Decision record has no rationale or thinking
- **WHEN** the Host Agent reports a planner decision with null rationale and null thinking (e.g., cloud-proxy transport where these are not surfaced)
- **THEN** the persisted row stores NULL for both columns without error

#### Scenario: Decision record includes reusable action metadata
- **WHEN** the Host reports a device-action planner decision with a purpose and expected outcome
- **THEN** the persisted row stores both values separately from the executable tool arguments and the task API returns them to authorized readers

#### Scenario: Existing decision records without rationale or thinking remain readable
- **WHEN** the system queries a `planner_decision_log` row created before this migration
- **THEN** both `rationale` and `thinking` read as NULL, and the row is returned normally
