Multiple marketplace projects beyond this repo need the same auth and payment client logic. Duplicating it per-project drifts fast (auth bugs get fixed in one place, not others) and blocks a consistent security posture across projects — directly relevant to [../../backend/BACKEND-INTEGRATION.md](../../backend/BACKEND-INTEGRATION.md), which already treats auth/RBAC as the single most serious cross-cutting concern.
-`@marketplaces/payment` — payment/finance client gateways, FX/pricing models, checkout client contracts (thin — business logic stays backend per Phase 1/7).
Each package:
1. Lives in its own git repo (handed over separately; this repo does not host it long-term).
2. Is consumed by `marketplaces` (and other projects) as an installed node_modules dependency — imported, never copy-pasted.
3. Is versioned with semver; CI on the package repo auto-bumps and publishes on push to `main`, driven by conventional commit prefixes already used in this repo (`feat:`/`fix:`/etc — semantic-release reads these directly).
4. Ships with its own test suite; `marketplaces` treats it as a black-box dependency, not source to edit in place.
Rollout order: scaffold packages and CI in this repo first (reversible, local-only) → hand over target git repo → publish → migrate `marketplaces` call sites to import from the package → delete the in-repo originals only after the app builds and passes tests against the package.
The original decision left distribution open ("private registry ... or installed straight from git"). A private Verdaccio registry was stood up on the dev server and both packages published to it. **That approach was then abandoned**: the registry listens on `127.0.0.1:4873` behind a firewall allowing only 80/443/SSH, so neither CI runners nor developers could install without an SSH tunnel. That broke `marketplaces`' existing `architecture-governance` workflow, whose `npm ci` step could no longer resolve `@marketplaces/auth`.
Distribution is now **git release branches**: `release/auth` and `release/payment` in vitanovaPackages, each an orphan branch whose root *is* the package (`package.json` + built `dist/`), force-pushed by CI on every release. Consumers install with `git+<repo>#release/auth` — no registry, no token, no tunnel, no CI secret; anonymous git read suffices.
The Verdaccio instance still runs but nothing depends on it. Making a registry the primary path again would require a reverse proxy plus TLS on the dev server, which buys nothing over the current approach at this scale.
-`marketplaces` loses direct edit access to auth/payment source — changes go through the package's own repo/PR/release cycle. Slower iteration, but consistent behavior across all consuming projects.
- ~30 call sites in `marketplaces` (see `core/auth`, `core/admin-auth`, `services/auth.service.ts`, interceptors) need import rewiring during migration — tracked as follow-up work, not done in this ADR.
- New failure mode: `marketplaces` builds now depend on `sources.vitanova.network` being reachable. A branch ref also tracks its tip, so an install can pick up a new build — acceptable while the package churns, but pin to a commit SHA once it stabilises.
- [../../backend/BACKEND-INTEGRATION.md](../../backend/BACKEND-INTEGRATION.md) §8 (admin provisioning) becomes package-owned behavior once migrated — that doc's endpoint contracts stay backend-side and unaffected, only the frontend client implementation moves.
