Phase D: Slot Assignment & Publishing

Last Updated: 2026-06-13 — Speaker states aligned to the 8-state model (ADR-009 / Epic 11); the removed slot_assigned / confirmed states replaced by derived is_slot_assigned / is_publishable flags.

# Overview

Phase D assigns approved speakers to specific time slots and publishes the finalized agenda.

Key Concept: Slot assignment does not change the speaker’s workflow state. When you assign a QUALITY_REVIEWED speaker to a time slot (sets session.start_time), the derived flag is_slot_assigned becomes true, which makes is_publishable (QUALITY_REVIEWED AND is_slot_assigned) true. There is no separate slot_assigned or confirmed state under ADR-009 — those are read-time derived flags.

Key Deliverable: Published event agenda with complete schedule and all assigned speakers publishable

# Slot Assignment

Navigate to the Speakers tab and switch to Sessions view to manage slot assignments.

Click Manage Slot Assignments to open the assignment interface.

Before auto-assignment:

# Publishing the Agenda

After assigning all sessions to slots, navigate to the Publishing tab.

Before publishing the agenda:

Click Publish Agenda to make the schedule public:

# Step 9: Assign Speakers to Time Slots

Implemented

# Purpose

Assign approved presentations to available event time slots using the auto-assign feature.

# Acceptance Criteria

• ✅ All approved presentations assigned to slots
• ✅ Schedule conflicts resolved automatically
• ✅ Event ready for agenda publication

# How to Use Auto-Assign

The system automatically assigns presentations to available slots, balancing the schedule and avoiding conflicts.

# Step 10: Publish the Agenda

Implemented

# Purpose

Make the finalized event agenda publicly available to attendees and stakeholders.

# How to Publish

# Phase D Completion

# Success Criteria

• ✅ All approved presentations assigned to time slots
• ✅ Schedule conflicts resolved
• ✅ Agenda published successfully
• ✅ Event state = AGENDA_PUBLISHED

# Late Withdrawals by Publishable Speakers

A speaker who is already QUALITY_REVIEWED and scheduled (i.e. is_publishable) can still drop out. Move them to terminal DECLINED (the previous state + reason are recorded in speaker_status_history) to free the slot. Freeing a slot lets the slot-capacity gate admit another READY → INVITED, so you can promote and invite a backup candidate.

# What Happens Next

Phase E: Archival (post-event):

• Event archival process
• Historical data preservation
• Reporting and analytics

See Phase E: Publishing → for archival procedures.

# Troubleshooting Phase D

# “Auto-assign fails with scheduling conflicts”

Problem: Auto-assign cannot find valid assignment for all presentations.

Solution:

• Check for over-booking (more presentations than available slots)
• Review speaker availability constraints that may conflict
• Manually assign problematic presentations first, then auto-assign remainder
• Consider adding more time slots or removing lower-priority presentations

# “Cannot publish agenda - missing slot assignments”

Problem: Agenda publication blocked due to unassigned presentations.

Solution:

• Return to slot assignment interface
• Ensure all approved presentations have time slots
• Use auto-assign to fill remaining slots
• Verify all assignments saved before attempting publication

# “Published agenda shows incorrect schedule”

Problem: Public agenda doesn’t match assigned slots.

Solution:

• Clear browser cache and refresh event page
• Verify assignments were saved correctly in slot management
• Re-publish agenda from Publishing tab
• Check that no manual edits were lost during save
