Foundation — Verified Human Governance on Solana

A decentralized governance platform that answers "who is a real human?" before "what do they want?". Foundation combines passport-backed Proof-of-Humanity, anonymous Semaphore voting, and on-chain Solana auditability. It's the first of three pillars in the PlantagoAI ecosystem — Your Voice (governance), Your Share (UBI distribution), Your Market (collective commerce) — all riding the same identity and voting rails.

Status: working prototype on Solana devnet. YC Summer 2026 application due May 4, 2026.

Phase 4/5 cutover (2026-04-19): the prior REST gateway tier was retired. Writes now go through httpsCallable onto Cloud Functions; reads are Firestore-direct via helpers from @plantagoai/firebase-core. The on-chain Anchor program lives in evoting-backend/programs/fresh-evoting/. Retired code lives under archive/rocket-retirement-2026-04-19/.

Shared @plantagoai/* packages

All 12 live under /Users/dagan/dev/shared/packages/. Prefer them over raw SDK calls — check docs/packages-overview.md and docs/pkg-*.md for APIs.

Import pattern (Cloud Functions / frontend):

"@plantagoai/auth": "file:../../shared/packages/auth"

Cloud Functions surface

25 httpsCallable callables + 9 triggers / onRequest endpoints, all wrapped by functions/lib/app-check.js::callable() which enforces App Check when ENFORCE_APP_CHECK=true. Grouped by domain:

Governance (Solana write path)

• createVoterAccount · createProposal · castVote · submitSupport
• activateProposal · solanaClientSmokeTest

Proof-of-Humanity

• verifyPassportProof (Self Protocol ZK) · attachSemaphoreCommitment
• rebuildSemaphoreGroups (trigger) · getSemaphoreGroup · verifyAnonymousVote
• approveManualReview · flagUserAbuse · unflagUserAbuse

AI

• evaluateProposal (Claude constitutional review with prompt caching)
• lookupPopulation (AI-assisted population lookup, trigger-driven)

Messaging

• sendMail (trigger) · sendNotification · sendInviteEmail (trigger)

Auth / access

• checkInviteOnSignup (beforeUserCreated trigger)
• approveAccessRequest · rejectAccessRequest · inviteDirect
• setAllowSelfRequest · requestSelfAccess
• adminStatus (onRequest) — admin-ring diagnostic

Legal + GDPR

• getPrivacyPolicy · getTermsOfService · recordTosAcceptance
• checkTosAcceptance · deleteMyAccount · exportMyData
• requestAccountDeletion · cancelAccountDeletion

See functions/index.js, functions/account-deletion.js, functions/legal.js, functions/admin-status.js for implementations.

Local development

Prerequisites

• Node.js 22+ (Cloud Functions runtime)
• Firebase CLI (npm i -g firebase-tools)
• Rust + Anchor CLI 0.31.1 + Solana CLI 1.18.26+ (only if touching the program — see scripts/install-toolchain.sh)

Frontend

cd evoting-frontend
npm install
npm run dev              # http://localhost:5173

Copy .env.example → .env.local and fill in devnet keys + reCAPTCHA site key. The frontend talks to Firestore directly and invokes Cloud Functions via httpsCallable — no intermediate API server.

Cloud Functions emulator

cd functions
npm install
npm run serve            # Firebase emulator suite

Anchor program

cd evoting-backend
anchor build             # produces target/idl/fresh_evoting.json
../scripts/sync-idl.sh   # copies IDL into functions/idl/

See docs/architecture_backend-consolidation-2026-04-18.md for the full current-state architecture description.

Testing

Deployment

Five Firebase Hosting targets (single Firebase project solanavote-devnet):

# Primary: deploy frontend + docs + yc site
firebase deploy --only hosting:foundation,hosting:docs,hosting:yc

# All hosting targets
firebase deploy --only hosting

# Cloud Functions
firebase deploy --only functions       # or ./scripts/deploy-functions.sh

scripts/deploy-functions.sh handles the @plantagoai/* monorepo bundle step before invoking firebase deploy. See docs/architecture_backend-consolidation-2026-04-18.md for the full Functions deployment story.

After rebuilding the on-chain program:

cd evoting-backend && anchor build
./scripts/sync-idl.sh    # fails loudly if target/idl/fresh_evoting.json is missing

Security posture

April 2026 brought a focused security sprint. See docs/security-hardening-2026-04.md for the full write-up. Highlights:

• App Check enforced on every callable via functions/lib/app-check.js (commit b997a66c, 2026-04-20)
• Governance client writes locked behind Zod schemas + auth (commits 9d8e23ca, 5e4792ab)
• CSP now allows reCAPTCHA Enterprise telemetry in both connect-src and script-src/frame-src (commits 52ee1cb4, a726374f)
• identity_proofs locked to server-only writes; manual-review photos moved from Firestore to Cloud Storage (commits 6a641d82, ed6381bf)
• Threat model + abuse registry shipped as part of PoH Phase 4 (commit 2f5ccd5b)

For the current threat model and remediation backlog see docs/poh-threat-model.md and docs/security-fix-plan-2026-04-20.md.
