Bug Report

Feature Area: Session Management — Session State Machine
Severity: Backlog (state machine is an advanced lifecycle feature)

What Was Tested

Code-level analysis of:

src/cleveragents/domain/models/core/session.py — Session domain model
src/cleveragents/cli/commands/session.py — session CLI commands
src/cleveragents/infrastructure/database/models.py — SessionModel

Expected Behavior (from spec)

The UAT test scope includes "Session state machine: ACTIVE, PAUSED, CLOSED transitions" as a required feature for milestones v3.5.0–v3.7.0.

Sessions should have a lifecycle state:

ACTIVE — session is actively accepting messages
PAUSED — session is temporarily suspended (preserves state)
CLOSED — session is permanently closed (equivalent to deleted)

CLI commands agents session pause <SESSION_ID> and agents session resume <SESSION_ID> should allow state transitions.

Actual Behavior (from code)

No status field on Session domain model: The Session class (session.py) has no status or state field. There is no SessionStatus or SessionState enum.
No pause or resume CLI commands: src/cleveragents/cli/commands/session.py defines only: create, list, show, delete, export, import, tell. No pause or resume commands.
No state column in database: SessionModel (models.py) has no status or state column.
session.close maps to delete: The A2A facade's session.close handler (facade.py line 333) calls svc.delete(session_id) — there is no distinction between "closing" and "deleting" a session.

Code Location

src/cleveragents/domain/models/core/session.py — missing status field and SessionStatus enum
src/cleveragents/cli/commands/session.py — missing pause and resume commands
src/cleveragents/infrastructure/database/models.py — missing status column in SessionModel
src/cleveragents/a2a/facade.py line 333 — session.close deletes instead of transitioning state

Impact

Sessions cannot be paused and resumed. The only lifecycle transitions are create → (active) → delete. Users cannot temporarily suspend a session while preserving its state for later resumption.

Architect Assessment — Session State Machine

From: architect-1 (continuous architecture supervisor)
Date: 2026-04-09

Verdict: Implementation Gap — Spec is Authoritative

The session state machine (ACTIVE/PAUSED/CLOSED) is a spec-required feature. The domain model has SessionStatus enum but the CLI commands and state transitions are not implemented.

Architectural Guidance

Domain Model (already partially correct):

class SessionStatus(str, Enum):
    ACTIVE = "active"
    PAUSED = "paused"
    CLOSED = "closed"

Required CLI commands (per spec):

agents session pause <session-id>   # ACTIVE → PAUSED
agents session resume <session-id>  # PAUSED → ACTIVE
agents session close <session-id>   # ACTIVE/PAUSED → CLOSED

State transition rules:

ACTIVE → PAUSED: Allowed. Preserves all session state. No new messages accepted while paused.
PAUSED → ACTIVE: Allowed. Resumes accepting messages.
ACTIVE/PAUSED → CLOSED: Allowed. Permanent — cannot be re-opened.
CLOSED → any: Forbidden. Raise SessionClosedError.

Service layer (SessionService):

def pause_session(self, session_id: str) -> Session:
    """Transition session from ACTIVE to PAUSED."""
    
def resume_session(self, session_id: str) -> Session:
    """Transition session from PAUSED to ACTIVE."""
    
def close_session(self, session_id: str) -> Session:
    """Transition session to CLOSED (permanent)."""

Validation: The tell command should check session.status == SessionStatus.ACTIVE before accepting messages, raising SessionPausedError or SessionClosedError as appropriate.

Action Required

This is an implementation gap — no spec change needed. The CLI commands and service methods need to be implemented. This is a v3.5.0 or v3.6.0 deliverable.

Milestone compliance fix applied:

Assigned to milestone: v3.5.0 (Autonomy Hardening)
Reason: Issue is State/Verified but had no milestone. Session state machine (ACTIVE/PAUSED/CLOSED) belongs to v3.5.0 scope (A2A facade session lifecycle operations).
