-- Teams-for-loops foundation. The `teams` table already exists (see
-- 0010_teams.sql) — a workspace-scoped topology graph + node→claw
-- bindings via team_members. This migration adds only the fields
-- needed to make an existing team attachable to a loop or research
-- topic with its own runtime constitution.
--
-- Motivation: today the paired coding loop reuses the research topic's
-- ZeroClaw team container, which forces one risk_profile on both the
-- read-heavy research workload and the write-heavy coding workload.
-- Attaching a distinct team lets a loop bring its own risk_profile
-- (e.g. "coding_readwrite" allowing file_write + shell) without
-- weakening the research team's posture.
--
-- Backward compat: every new column is NULLABLE. NULL preserves the
-- legacy "inherit from wherever the runtime template says" behavior.
-- No existing row is invalidated; wizards + runtime opt into the new
-- fields in follow-up slices.

-- Per-team runtime posture. NULL falls back to the runtime template
-- default (currently `research_readonly` for research-spawned
-- containers). Named profiles resolve at daemon startup against
-- [risk_profiles.<name>] in the runtime config.
ALTER TABLE teams
    ADD COLUMN IF NOT EXISTS risk_profile TEXT;

-- Extra MCP bundle aliases the team's agents load in addition to the
-- template defaults. Stored as JSONB array of strings so a team can
-- carry {"clawmates_door", "git_writer"} for a coding pair without
-- affecting other teams. Empty array = inherit template only.
