markOnboardingStepDone read space_members.onboarding_progress, appended the step id in JS, and wrote the whole jsonb object back — a lost-update race where two near-simultaneous completions (double-submit, or two steps ticked quickly) both read the same base array and the second write clobbered the first, silently dropping a step. Replace it with mark_onboarding_step_done (migration 055): a single atomic UPDATE that dedup-appends the step id into onboarding_progress.completed_step_ids under the row lock — no update can be lost (READ COMMITTED re-evaluates the jsonb expression against the latest tuple via EvalPlanQual), other keys are preserved, and re-appending an existing id is a no-op. Ownership-guarded by auth.uid() so a caller can only complete steps on their own membership row; the no-JWT service path is trusted and scoped by p_member_id (mirrors class_signup_tx et al.). integration/onboarding-progress.test.ts covers dedup/idempotency, key preservation, the auth.uid ownership gate, and the point of the fix: 12 concurrent completions all survive. Migration 055 folded into schema.sql; types/database.ts regenerated. typecheck 0 · lint 0 errors · 645 unit · 58 integration · build ok
hackerspace-management
A multi-tenant operating system for hackerspaces, makerspaces, and member-run shops. One installation can host many independent spaces. Each space owns its own members, tasks, projects, payments, knowledge base, proposals, incidents, policies, and chat channels. All data access is enforced at the database with row-level security.
- Live site: https://hackerspace.sh
- Source: https://github.com/virgilvox/hackerspace-management
Features
- Members and tiers. Roster, tiers (Plus, Basic, Associate), built-in roles, custom roles, state (current, late, inactive, unverified), per-member skills. A per-space permissions matrix grants capabilities to any role additively, on top of role-based RLS.
- Tasks and projects. Project boards, task assignment, status, area tagging, priority, comments.
- Operations. Markdown knowledge base and processes (with working in-document anchor links), an AES-256-GCM secrets vault revealed on demand, per-item Ops ACLs, area leads.
- Forms and waivers. An easy builder for arbitrary forms and signable waivers. Public (anonymous or signed-in) or members-only; per-submission snapshots of schema and legal text so a waiver stays valid against exactly what was signed; CSV export; optional onboarding step.
- Certifications and instructors. Certification types with optional validity periods; an Instructor capability awards and revokes them; expiry and revocation tracked; members see their own record.
- Classes. Class offerings with scheduled sessions, member signup with waitlists, attendance, and an optional certification granted on completion.
- Equipment. Tool and equipment registry with time-window reservations, no-overlap enforcement, and an optional required certification per item.
- Access control. Member access cards (the card UID is treated as a credential), a configurable per-space door integration (native HeatSync controller or generic HTTP) behind an SSRF-guarded executor, live grant/revoke/open and member self-entry, inbound access-log ingest (a HeatSync
?zpoll plus a per-connection authenticated webhook, each card matched back to a member), and an immutable, secret-redacted access log. A universal API-call button builder generalizes this: admins define permission-gated buttons (any HTTP verb, headers, body, vault-stored secret) that fire through the same hardened egress, with a door-control preset. - Onboarding and invites. A configurable member onboarding flow; multi-use, expiring, role-granting invite links.
- Payments and financials. Per-member payment ledger, integration credentials per space, exports, monthly financial summary. Stripe recurring dues are a first-class integration: each space configures its own Stripe account (not Connect), members pay through hosted Checkout and self-serve cancel/update through the hosted Billing Portal (no card data on our servers), and a per-space signed webhook keeps
member_billingand member status (current/late) in sync, never auto-downgrading pastlate. - Transactional email and notifications. An idempotent notifications outbox writes dues-lifecycle emails (renewal receipt, payment failed, lapse) from the Stripe webhook; a small dispatcher cron drains them through Resend with a fair per-space queue and per-attempt idempotency. Adding other domains (bookings, forms) reuses the same outbox.
- Member self-serve portal. Every member's
/meis a tabbed portal: profile editing, dues management (Pay / Manage Billing), cancel class signups and equipment reservations, a personal payment history, and a verified self-service email change. - Governance. Proposals with quorum, vote tracking and expiry; incident reports with anonymous reporter tracking by token; versioned policy library; member forum with polymorphic comments.
- Communications. Multi-channel chat with realtime delivery.
- Recruitment. Public-facing recruitment page per space.
- API. PostgREST-generated REST for every table, gated by RLS. Webhook HMAC signing contract + secret rotation are defined; per-event delivery is a follow-up (see docs/WEBHOOKS.md).

Quick start (local development)
Requirements: Node.js 20 or later, pnpm 10 or later, Docker (for the local Supabase CLI), git.
git clone https://github.com/virgilvox/hackerspace-management.git
cd hackerspace-management
pnpm install
cp .env.example .env.local
Edit .env.local with values from your local Supabase project (see docs/LOCAL_DEV.md to start one in seconds using the Supabase CLI), then:
pnpm dev
Open http://localhost:3000, sign up, create a space, you land on the dashboard.
Detailed local setup: docs/LOCAL_DEV.md.
Production deployment
The supported production target is a single DigitalOcean Droplet running self-hosted Supabase plus the Next.js app behind Caddy with Let's Encrypt. No managed Supabase, no third-party application data store.
End-to-end guide: docs/DEPLOY_DO_SELFHOSTED.md.
Summary:
- Provision a Droplet (4 GB RAM, 2 vCPU, 80 GB disk recommended).
- Attach a block volume mounted at
/mnt/datafor the Postgres data directory and backups. - Point DNS A records for your domain,
www,supabase,studioat the Droplet. - Run the bootstrap script in
scripts/to install Docker, Supabase, Node, Caddy, the app, the systemd unit, backup cron, and the deploy hook. - Push to
main. GitHub Actions runsdeploy.shon the Droplet over SSH: pull, install, apply pending migrations, build, restart.
The deploy script is idempotent and tracked: every numbered migration in scripts/ is recorded in public._migrations_applied. New migrations are applied automatically on push.
Database
scripts/schema.sql is the canonical, idempotent, full schema. Run it once on a fresh Supabase project. Subsequent changes are added as numbered migrations (scripts/021_*.sql, 022_*.sql, etc.) and applied incrementally.

The system is feature-functional and serving production traffic at hackerspace.sh. The running session log, deploy state, and rolling security audits live in docs/HANDOFF.md (newest on top). docs/AUDIT.md is a deeper full-codebase audit snapshot from 2026-05-14 (historical context).
