Directly addresses "we want to pick one or more teams to assign to a
mission, first screen research teams, next screen dev teams." A
mission now materializes N teams, each tagged with a phase purpose.
Backend:
- 0056_mission_teams.sql — new join table
mission_teams(mission_id, team_id, purpose). team_id PK because a
team belongs to one mission-purpose. missions.team_id kept as
legacy pointer to the first minted team for single-team surfaces.
- mission_orchestrator::on_launch — reads mission.config.phase_teams
(JSONB shape { research: [tid,...], coding: [tid,...] }), mints
one team per (purpose, template) pair, records each in
mission_teams, binds the first to mission.team_id. Legacy fallback:
if config.phase_teams is absent, uses missions.team_template_id.
Hard error if both are absent.
- GET /api/missions/{id}/teams — returns
[{ team_id, purpose, team_name }], sorted by created_at asc.
Frontend wizard (step 3 rewrite):
- researchTeamIds / devTeamIds — Set<string> multi-selects
- Reusable TeamMultiSelect component (checkbox-style cards)
- Panels rendered conditionally by preset:
hasResearchPhase → "Research teams" panel
hasCodingPhase → "Development teams" panel
neither → "Teams" panel (bench/security-only missions)
- canNext enforces at least one pick in every visible panel
- submit builds config.phase_teams and passes it via CreateMissionRequest
- Review step shows both selections by name
MissionTeamTab:
- Fetches /api/missions/{id}/teams and groups by purpose
- Each purpose renders a section with per-team cards
- Falls back to a single "mission" pseudo-row for legacy missions
that only have missions.team_id (no mission_teams rows)
CreateMissionRequest no longer sends team_template_id from the wizard
— the multi-team config.phase_teams path supersedes it. The backend
still accepts team_template_id for API callers.
Verified: cargo check --workspace + tsc + eslint --quiet all green.
