# Quickstart — 093 Workspace ID Isolation
## Goal
Run the staged rollout locally/staging to ensure all tenant-owned tables are workspace-bound and audit invariants hold.
## Prereqs
- Sail is running: `vendor/bin/sail up -d`
- DB is migrated: `vendor/bin/sail artisan migrate`
## Rollout Order
1) **Phase 1** — Add nullable `workspace_id` columns + indexes
- Deploy migrations
2) **Phase 1.5** — Deploy app write-path enforcement
- New/updated tenant-owned writes derive `workspace_id` from `tenant.workspace_id`
- Mismatches are rejected
3) **Phase 2** — Backfill existing rows
- Dry-run:
- `vendor/bin/sail artisan tenantpilot:backfill-workspace-ids --dry-run`
- Execute:
- `vendor/bin/sail artisan tenantpilot:backfill-workspace-ids`
4) **Phase 3** — Enforce constraints + validate + final indexes
- Apply NOT NULL + FKs + composite FKs
- Add audit_logs check constraint
## Validation SQL (Postgres)
Run these to confirm no missing bindings remain.
Tenant-owned tables:
- `SELECT count(*) FROM policies WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM policy_versions WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM backup_sets WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM backup_items WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM restore_runs WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM backup_schedules WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM inventory_items WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM inventory_links WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM entra_groups WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM findings WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM entra_role_definitions WHERE workspace_id IS NULL;`
- `SELECT count(*) FROM tenant_permissions WHERE workspace_id IS NULL;`
Audit invariant:
- `SELECT count(*) FROM audit_logs WHERE tenant_id IS NOT NULL AND workspace_id IS NULL;`
## Rollback notes
- Phase 1 migrations are reversible (drop columns / indexes) but may be large operations on production datasets.
- Prefer forward-fix for production if Phase 2/3 is partially applied.
