Publaryn – Complete Concept for an Independent Multi-Ecosystem Package Platform

1. Executive Summary

Publaryn is an independent platform for hosting, managing, securing, and publishing software packages across multiple ecosystems. It is designed to support both public and private packages and to give individual users as well as organizations a unified, secure, and user-friendly way to publish, manage, and consume packages.

The initial ecosystems are:

• npm
• Bun
• Composer
• NuGet
• RubyGems
• Apache Maven
• Containers / OCI
• pip
• Rust Crates

The platform is built around a Rust-based backend as the registry and domain core, combined with a Bun-managed TypeScript web interface built with SvelteKit and Tailwind CSS. The current frontend baseline already covers landing, search, package detail, version detail, login, register, settings, and dedicated organization workspaces through native SvelteKit routes and a persisted theme-aware shell. The settings experience includes profile editing, TOTP-based MFA with recovery codes, scoped token management, organization memberships, invitation acceptance and decline, and organization creation. Dedicated organization workspaces now cover member and invitation administration, teams, repository and namespace management, audit dashboards, security overviews, and package transfer flows. The goal is to match at least the functional baseline of established hosting and registry services such as npmjs.org, PyPI, RubyGems.org, NuGet.org, and OCI/container registries, while exceeding them in security, governance, user experience, and multi-ecosystem consistency.

Publaryn should be designed from the beginning to work as:

• a managed SaaS platform
• a self-hosted enterprise deployment
• and, later, potentially a federated registry infrastructure

---

2. Product Vision and Positioning

2.1 Vision

Publaryn becomes a neutral, trustworthy infrastructure layer for software supply chains and package distribution across programming languages and build ecosystems.

It solves a fragmented problem space:

• every ecosystem has its own registry conventions
• organizations often use many ecosystems in parallel
• security, governance, and policy enforcement are inconsistent
• self-hosting is often difficult or incomplete
• many existing solutions are either too specialized or not user-friendly enough

Publaryn unifies these worlds without breaking native client tooling and workflows.

2.2 Positioning

Publaryn is not just a file hosting service and not just a generic artifact store. It is a:

• policy-aware
• security-first
• multi-tenant
• multi-ecosystem
• developer-friendly package registry platform

2.3 Target Audiences

Primary audiences:

• open-source maintainers
• small and medium software teams
• startups
• large organizations using multiple package ecosystems
• platform engineering teams
• developer experience teams
• security and supply-chain teams

Secondary audiences:

• universities and research institutions
• public sector organizations
• open-source communities
• managed development platform providers

---

3. Core Problems Publaryn Solves

3.1 Fragmentation of Package Infrastructure

Teams often use several ecosystems simultaneously:

• npm for frontend
• pip for data or automation
• Maven or NuGet for enterprise backends
• OCI for deployment artifacts
• Cargo for systems tooling
• Composer or RubyGems in legacy or specialized environments

Today this typically requires running multiple disconnected tools and registries.

3.2 Insufficient Security

Traditional registry systems often provide:

• overly broad tokens
• weak default security
• limited auditability
• poor typosquatting protection
• no clear provenance model
• unclear deletion and takedown processes

3.3 Poor User Experience

Many registry interfaces are:

• technical but hard to navigate
• unfriendly for teams
• weak at organization and governance workflows
• inconsistent between ecosystems
• poor in search, discovery, and setup guidance

3.4 Weak Organization and Permission Models

Many platforms lack strong support for:

• role and team structures
• org-wide policy enforcement
• clear separation between public and private packages
• CI-based trusted publishing
• security dashboards and audit workflows

Publaryn already closes much of this gap at the domain, API, and frontend layers: organizations, invitations, teams, ownership transfer, delegated package, repository, and namespace access, and dedicated organization workspaces are present in the current stack.

---

4. Non-Functional Guiding Principles

4.1 Security First

Every product and architecture decision should strengthen software supply-chain security.

4.2 Native Client Compatibility

Developers must be able to continue using their existing tools:

• npm
• bun
• pip and twine
• cargo
• docker and podman
• nuget
• mvn and gradle
• gem
• composer

4.3 Consistency Over Maximum Speed

A publish operation must appear reliably and atomically.

4.4 Immutability by Default

Published artifacts should be immutable by design.

4.5 Good UX Is a Security Feature

If secure behavior is easier than insecure behavior, real security improves.

4.6 Openness and Portability

The platform should be exportable, well documented, and designed to avoid hard vendor lock-in.

---

5. Scope and Product Boundaries

5.1 In Scope

• a complete CI platform
• source code hosting
• a general-purpose binary artifact manager beyond supported package types
• operating a certificate authority for code signing

---

6. System Architecture

6.1 Architecture Approach

Recommended approach: a modular monolith with clearly separated domain modules and asynchronous worker components.

Why:

• strong domain consistency is required
• many business rules are tightly connected
• publish transactions are critical
• moving too early into microservices would add major complexity

Later, selected components can be split out:

• search
• scanning
• eventing
• analytics
• notifications
• OCI blob handling

6.2 Main Layers

Presentation Layer

• Bun-managed TypeScript web portal built with SvelteKit, Tailwind CSS, and lightweight client stores
• public package discovery and detail pages
• authentication and personal account settings for profile editing, TOTP MFA, scoped tokens, organization discovery, invitation review, and organization creation
• dedicated organization workspaces, team management, audit views, and security dashboards delivered through native SvelteKit routes
• future security and compliance views layered onto the same frontend foundation

API Layer

• management API for the UI and automation
• native registry endpoints per ecosystem
• auth and OIDC integrations
• webhooks and event-outbox behavior as a post-1.0 extension

Domain Layer

• user, organization, team
• package, release, artifact
• namespace and ownership
• policy engine
• security findings
• audit log
• search metadata
• lifecycle and visibility metadata

Infrastructure Layer

• relational database
• object storage
• cache
• event queue
• search index
• scanning subsystem
• monitoring and logging

---

7. Bounded Contexts / Domain Modules

7.1 Identity and Access

Responsible for:

• user accounts
• sessions
• TOTP MFA today; passkeys / WebAuthn after 1.0
• tokens
• roles and permissions
• SSO and enterprise identity after 1.0
• service identities

7.2 Organizations and Governance

Responsible for:

• organizations
• teams
• memberships
• roles
• invitations
• namespace claims
• policies
• delegated access and ownership transfer

The backend API already implements organization CRUD, memberships, invitations, teams, ownership transfer, and delegated package, repository, and namespace access. The current frontend exposes org discovery, join/decline, and creation flows in settings and dedicated organization workspaces.

7.3 Package Core

Responsible for:

• packages
• versions
• artifacts
• ownership
• tags and channels
• visibility
• releases
• deletion, yank, and deprecation

7.4 Protocol Adapters

Responsible for:

• npm and Bun registry compatibility
• PyPI Simple API and upload flows
• NuGet registry APIs
• RubyGems APIs
• Maven repository layout and metadata
• OCI Distribution API
• Cargo registry integration
• Composer metadata endpoints

7.5 Publish Pipeline

Responsible for:

• uploads
• quarantine
• validation
• checksums
• security scanning
• release activation

• provenance
• signatures
• policy enforcement
• abuse and takedowns
• risk scoring

Scanning, trusted publishing, and security findings are already anchored in the backend and are now exposed through package and organization security views in the current web application baseline. Broader operator tooling, deeper attestation workflows, and richer policy-driven remediation remain later slices.

7.8 Audit and Compliance

Responsible for:

• immutable audit events
• export
• reporting
• compliance-relevant data
• administrative forensics

Audit capture is already a backend concern and the current organization workspace now includes human-friendly audit views and CSV export. Broader compliance reporting, operator workflows, and signed audit-chain enhancements remain future work.

7.9 Notifications and Integrations

Responsible for:

• webhooks as a planned post-1.0 integration surface
• email
• chat notifications
• incident alerts
• CI/CD integrations

---

9. Roles and Permissions Model

9.1 Principles

• least privilege
• explicit scopes
• controlled inheritance
• separation between administration, publishing, and security rights

9.2 Permission Layers

Permissions should exist on multiple levels:

• instance level
• organization level
• repository level
• package level

9.3 Organization Roles

• Owner: full control
• Admin: management control, possibly excluding billing
• Maintainer: operational package maintenance
• Publisher: publish new versions
• Security Manager: security events, quarantine, takedowns
• Auditor: read-only access to logs and reports
• Viewer: read-only general access

9.4 Repository Roles

• Repository Admin
• Repository Publisher
• Repository Reader
• Repository Security Reviewer

9.5 Package Roles

• Package Admin
• Package Maintainer
• Package Publisher
• Package Viewer

9.6 Special Capabilities

• assign namespace rights
• transfer package ownership
• create CI publishing tokens
• yank releases
• unlist public packages
• place packages into security quarantine
• enforce provenance requirements

---

10. Organization Model

10.1 Why Organizations Are Central

The platform should model real teams and companies, not just individual maintainers.

10.2 Organization Features

• organization profile page
• verified domain
• team management
• member roles
• package overview
• namespace management
• policy management
• activity feed
• security status
• webhooks
• optionally billing and quotas

10.3 Teams

Teams are assignable to:

• entire repositories
• individual packages
• namespace areas
• security responsibilities
• audit visibility

10.4 Ownership Transfer

Common use cases:

• a personal project becomes an organization project
• a package moves from one org to another
• an individual maintainer leaves while the organization remains owner

Transfers must be:

• auditable
• policy-validated
• approval-based when necessary

---

11. Package Lifecycle

11.1 States

• Reserved
• Created
• In preparation
• Published
• Deprecated
• Yanked
• Unlisted
• Quarantined
• Archived
• Deleted or Tombstoned

11.2 Reservation

Useful for:

• project starts
• namespace protection
• planned product launches
• parallel team work

Reservations should be:

• time-limited
• renewable
• policy-controlled

11.3 Publishing

A publish operation may include:

• artifact upload
• metadata extraction
• security checks
• namespace validation
• release activation
• search indexing
• notifications

11.4 Deprecation

Should support:

• warning only
• warning with replacement package
• warning with end-of-life date
• security-critical deprecation

11.5 Yank

Needed for:

• broken releases
• withdrawn versions
• security issues

Behavior differs by ecosystem, but can be represented through a common model:

• not available for new installs
• existing locked references may still resolve depending on protocol rules

11.6 Archiving

For discontinued packages:

• still visible
• no longer actively maintained
• replacement guidance
• optionally read-only

---

12. Public, Private, Internal, and Hybrid Repositories

12.1 Public

Open to install, publicly visible, and indexable.

12.2 Private

Accessible only to authenticated and authorized users.

12.3 Internal

Visible and installable only within an organization.

12.4 Hybrid

Examples:

• public metadata with private artifacts
• public package with private prereleases
• internal staging and public release channels

---

13. Multi-Repository Strategy

13.1 Motivation

Professional use cases often require more than a single global package store.

13.2 Repository Types

• Hosted
• Proxy
• Group or Virtual
• Staging
• Quarantine
• Archive

The 1.0 baseline currently ships hosted repositories with public, private, staging, and release kinds. Proxy, group/virtual, archive- specific lifecycle policies, and broader promotion semantics remain later repository-lifecycle work.

13.3 Typical Flows

• developer publishes to staging
• security checks and approval happen
• promotion to public release
• old versions moved to archive
• external registries mirrored through proxy

13.4 Enterprise Advantages

• clear release approval flows
• reproducible sources
• centralized governance
• dependency control

---

14. Registry Protocols and Ecosystem-Specific Requirements

14.1 npm / Bun

Needs:

• scoped and unscoped packages
• dist-tags
• publish and unpublish policies
• deprecations
• token-based auth
• package metadata documents
• tarball handling

Bun should be supported via npm-compatible registry behavior.

14.2 pip / PyPI

Needs:

• Simple API
• uploads via compatible tools
• wheel and source distribution support
• hashes
• yanked releases
• name normalization
• strong support for index URL configuration

Especially important:

• dependency confusion protection
• robust implementation of normalization rules

14.3 Composer

Needs:

• package metadata
• dist and source references
• private authentication
• efficient metadata delivery
• strong caching behavior

14.4 NuGet

Needs:

• v3 service index
• package push
• registration
• flat container
• SemVer2 support
• search integration

14.5 RubyGems

Needs:

• push
• yank
• metadata
• compact index
• download statistics
• strong namespace protection

14.6 Maven

Needs:

• classic Maven repository layout
• metadata XML
• checksums
• release and snapshot flows
• group-based ownership
• staging and promotion are highly valuable

14.7 OCI / Containers

Needs:

• OCI Distribution API
• manifests
• layers
• tags
• multi-architecture manifest lists
• blob deduplication
• garbage collection
• mutable tags with immutable digests

The current 1.0 adapter baseline now includes inventory-backed background cleanup of unreferenced OCI config and layer blobs after manifest lifecycle changes, so self-hosted operators do not need a separate manual blob-GC loop for the documented OCI feature set.

14.8 Rust Crates / Cargo

Needs:

• alternative registry support
• sparse index
• publish
• yank
• owner management
• correct index synchronization behavior

---

15. API Strategy

15.1 Two API Worlds

Publaryn needs:

• native registry endpoints for package managers
• unified management APIs for the web UI, CLI, and automation

15.2 Management API

Responsible for:

• users and organizations
• packages and releases
• permissions
• search
• audit
• security findings
• tokens
• webhooks
• quotas
• reporting

15.3 Admin API

Separate or logically isolated for:

• global policies
• abuse handling
• quarantine management
• storage and queue health
• reindexing
• manual recovery flows

For 1.0 this operator surface remains intentionally narrow: platform administrators can use GET /v1/admin/jobs for queue visibility, stale-job detection, and filtered recovery checks, while broader operator consoles remain post-1.0 work.

15.4 Event API

Useful for:

• publish events
• release changes
• token revocations
• security findings
• takedown workflows

---

16. Frontend and UX Concept with SvelteKit

16.1 Target Experience

The interface should be:

• efficient for maintainers
• understandable for newcomers
• controllable for enterprises
• informative for visitors

The implemented frontend foundation already delivers the public landing, search, package detail, version detail, login, register, settings, and organization workspace flows together with a shared theme-aware shell. Routing runs through native SvelteKit file-based routes with a static-adapter build, so the immediate frontend goal is to keep growing governance, repository, package, and security surfaces without a legacy compatibility layer.

16.2 Main Areas of the Web Application

Current implemented baseline:

• landing and discovery
• search
• package detail pages
• version pages
• login and registration
• profile editing
• TOTP MFA setup, verification, and disable flows
• personal API token management
• organization membership overview
• organization invitation acceptance and decline
• organization creation
• dedicated organization workspaces
• team and delegated package, repository, and namespace access management
• repository and namespace management
• organization audit and security views
• package transfer flows
• shared theme-aware app shell

Next major expansion areas on the same frontend foundation:

• richer package management workflows
• broader administration area
• policy and compliance dashboards
• notifications and event surfacing
• administration area

16.3 Public Package Pages

Contents:

• package name and ecosystem
• owner or organization
• installation instructions
• latest version
• release history
• README
• changelog
• license
• download data
• security indicators
• verification and provenance signals
• related packages

16.4 Package Management UI

These workflows sit on top of the current public/search/settings baseline and the organization workspace.

The current implementation already exposes package settings, visibility controls, release management, tags and channels, delegated team access, security findings, trusted publishers, and transfer/archive actions directly from the package detail experience.

Remaining follow-on areas for maintainers include:

• broader maintainer management
• webhooks
• access policies
• richer delete or takedown workflows beyond archive controls

16.5 Organization UX

Strong organization management can become a major competitive advantage.

This remains a primary differentiator. The current implementation already lets users discover their organizations, accept or decline invitations, create new organizations from settings, and work inside dedicated organization workspaces for profile, members, invitations, teams, repositories, namespace claims, audit review, security overview, and package transfer.

Needs:

• clear team structure
• simple role assignment
• visible package responsibility
• transparent namespace verification
• central security policy controls

16.6 UX Principles

• secure defaults
• progressive disclosure
• clear error messages
• setup assistance instead of cryptic failure output
• actions should be understandable and reversible where possible
• ecosystem-aware information architecture

16.7 Role of SvelteKit and Tailwind

SvelteKit and Tailwind fit especially well for:

• native file-based routing and nested layouts
• persisted theme and session state via lightweight stores
• static-adapter output with SPA fallback served by the API
• safe rendering of README and markdown content
• stateful security and audit interfaces
• data-heavy governance forms without runtime framework ceremony

In the implemented frontend stack, SvelteKit provides routing, layouts, and compiled component delivery; Tailwind CSS handles layout, spacing, and utility styling; lightweight local stores manage session and theming concerns; and Bun drives dependency management and local workflows.

21.3 Tracing

Particularly valuable for publish pipelines and protocol adapters.

21.4 Operating Modes

• single-instance development
• small-team self-hosted
• high-availability SaaS
• enterprise on-premises
• later air-gapped enterprise variant

---

22. Storage Strategy

22.1 Metadata

A relational database stores:

• users
• roles
• packages
• releases
• policies
• audit data
• security findings
• namespace claims

22.2 Artifacts

Object storage holds:

• tarballs
• wheels
• JARs
• gems
• nupkg files
• OCI blobs
• checksums
• signatures
• SBOMs

22.3 Search Store

A dedicated search index supports fast discovery.

22.4 Analytics Store

Optionally separate, so download events do not overload the transactional system.

22.5 Content Addressing

Important for:

• deduplication
• integrity
• reproducibility
• efficient OCI storage

---

23. Scaling Strategy

23.1 Early Stage

• modular monolith

23.3 Later Stage

• regional replication
• global edge caching
• isolated scanning clusters
• analytics pipeline for downloads
• multi-availability-zone deployment
• notarized or chained event records

---

24. Availability and Consistency

24.1 Consistency Strategy

Strong functional consistency is important for publish and registry visibility. Eventual consistency is acceptable for search, analytics, and trending.

24.2 SLA-Oriented Service Classification

Critical:

• publish
• install and pull
• authentication
• token validation

Less critical:

• refined search ranking
• analytics dashboards
• recommendations

24.3 Failover

• database backups and point-in-time recovery

• job retry with idempotency

---

25. Data Deletion, Retention, and Privacy

25.1 Privacy

• clear data classification
• minimize personal data
• privacy-aware logging
• deletion concepts for user data

25.2 Deletion Model

Differentiate between:

• deleting a user account

29. 1.0 Release Roadmap

The foundation and MVP phases described earlier in this document are largely complete in the current implementation. Publaryn now ships all planned baseline adapter crates, a broad management API, a SvelteKit web portal, organization workspaces, delegated team governance, rate limiting, background jobs, and a quarantine-first publish pipeline.

The remaining roadmap to 1.0 is therefore no longer “build the first product” but “align, harden, document, and operationalize the shipped product”.

Phase 1 – Reality Alignment

• synchronize README, concept, ADR index, and the API/adapter matrix
• define the 1.0 product scope explicitly
• define what is intentionally deferred until after 1.0
• document search, visibility, security flows, and support expectations
• freeze a release contract that matches the real codebase

Phase 2 – Protocol Hardening

• validate native publish, read, auth, and yank/unlist flows for every mounted adapter
• add conformance-style regression coverage per ecosystem
• harden edge-case error behavior and compatibility gaps
• finish prioritized adapter polish for OCI, Cargo, PyPI, and Maven

Phase 3 – Security GA

• deepen the scanner subsystem
• surface advisory-driven and supply-chain-oriented findings more consistently
• formalize SBOM, provenance, and attestation direction
• extend quarantine, triage, and operator-oriented security workflows

Phase 4 – Governance GA

• mature invitation and identity-trust flows
• productize namespace and domain verification
• expand policy coverage for organizations, repositories, and packages
• harden approval, transfer, and delegation behavior
• complete audit and compliance-facing views

Phase 5 – Repository Lifecycle

• staging and promotion flows
• snapshot strategy where ecosystems require it
• proxy and virtual repository types
• retention, archive, and tombstone rules
• quota enforcement as a technical capability

Phase 6 – Operations and Integrations

• webhooks and event-outbox behavior
• admin and operator surfaces
• reindex, recovery, queue-health, and blob-GC workflows
• stronger monitoring, tracing, and deployment/operator documentation

Phase 7 – 1.0 Release Gate

• document a per-adapter definition of done
• complete security review and documentation freeze
• verify upgrade, migration, smoke, and install paths
• publish a support and compatibility policy

30. 1.0 Scope Recommendation

30.1 What 1.0 Should Include

Publaryn 1.0 should include:

• all currently mounted ecosystems: npm/Bun, PyPI, Cargo, NuGet, Maven, RubyGems, Composer, and OCI
• hosted repository kinds public, private, staging, and release
• the existing management API for auth, governance, packages, releases, search, security findings, and trusted publishers
• public and authenticated private discovery with visibility-aware search
• the existing web portal baseline: landing, search, package pages, version pages, settings, MFA, token management, and organization workspaces
• organization teams, delegated package/repository/namespace access, and ownership-transfer flows
• background scanning, queue processing, and release reindexing

30.2 What 1.0 Should Explicitly Exclude

• full enterprise identity integration such as SSO, SAML, and SCIM
• monetization and billing systems
• federated or globally replicated registry behavior
• proxy, mirror, and virtual repositories unless explicitly completed and documented
• Maven snapshot repositories and promotion workflows
• full-featured provenance and attestation product workflows
• air-gapped synchronization and offline replication tooling
• operator-facing abuse and takedown consoles beyond the current quarantine and audit primitives
• richer discovery, ranking, and recommendation surfaces

30.3 API and Adapter Matrix for 1.0

The control-plane baseline for 1.0 is:

• /v1/auth/*
• /v1/users/*
• /v1/orgs/*
• /v1/org-invitations/*
• /v1/namespaces/*
• /v1/repositories/*
• /v1/packages/*
• GET /v1/search
• package security-finding and trusted-publisher routes under /v1/packages/*
• organization security reporting under /v1/orgs/*
• /v1/tokens*
• /v1/audit
• /v1/admin/jobs
• /v1/stats
• /health
• /readiness

The mounted native adapter baseline for 1.0 is:

Ecosystem	Mount path	1.0 baseline
npm / Bun	/npm	packument reads, tarball download, search, publish, dist-tags
PyPI / pip	/pypi plus /_/oidc/*	Simple API, file download, legacy upload, trusted-publishing token exchange
Cargo	/cargo/index, /cargo/api/v1	sparse index, publish, download, search, yank, unyank, compatibility owner endpoints
NuGet	/nuget	service index, flat container, registration, search, push, unlist, relist
Maven	/maven	repository reads, metadata generation, checksum reads, deploy-style PUT upload
RubyGems	/rubygems	metadata reads, version listing, gem download, push, yank, API key echo
Composer	/composer	packages index, package metadata, dist download, publish, yank
OCI	/oci	probe, catalog, manifests, blobs, uploads, tags, referrers, delete semantics, orphaned blob cleanup

30.4 Search, Visibility, and Security Contract for 1.0

• anonymous search only returns public packages
• authenticated search can include visible private and internal_org packages through owner access, organization membership, or delegated team access
• org and repository filters narrow the visible search result set
• unlisted packages stay readable via direct URL but remain out of search and package listings
• quarantine and scanning releases stay hidden from public protocol reads and public artifact downloads
• publish flows remain quarantine-first: create/resolve the release, store immutable artifacts, enqueue scan/index work, then expose the release when publication rules are satisfied
• 1.0 account security means password login, JWT sessions, scoped API tokens, TOTP MFA with recovery codes, and rate limiting; passkeys and enterprise federation remain later work

30.5 Release Criteria for 1.0

Publaryn 1.0 should only ship when:

1. README, this concept, docs/1.0.md, and the ADR index agree on scope and deferrals.
2. Every mounted adapter has documented route scope plus targeted regression coverage for publish/read/auth behavior.
3. The documented Rust and frontend CI checks pass.
4. The Docker smoke build passes.
5. Release notes clearly separate supported, unsupported, and deferred features.

31. Risks and Mitigations

31.1 Protocol Complexity

Risk: Each ecosystem has subtle and non-obvious requirements.

Mitigation:

• adapter-oriented architecture
• conformance test suites
• incremental rollout per ecosystem

31.2 Security Responsibility

Risk: Operating a package registry is security-critical.

Mitigation:

• security designed into the core
• external audits
• limited token scopes
• OIDC publishing
• immutable artifacts
• abuse handling workflows

31.3 Operational Complexity

Risk: Search, blob storage, scanning, and protocol compatibility are operationally demanding.

Mitigation:

• modular monolith approach
• strong operational standards
• deep observability
• gradual decomposition later

31.4 UX Overload

Risk: Multi-ecosystem support can become confusing.

Mitigation:

• ecosystem-specific UX paths
• common domain model without forcing identical UI everywhere
• progressive disclosure

31.5 Legal and Abuse Issues

Risk: Trademark conflicts, malware distribution, takedown requests.

Mitigation:

• clear policies
• reporting and moderation workflows
• quarantine
• auditability
• legally sound terms and procedures

33. Recommended Foundational Technical Decisions

33.1 Rust as the Core

Rust is a strong fit for:

• performance
• memory and type safety
• controlled resource usage
• high reliability
• protocol-serving and worker execution

33.2 SvelteKit as the Web Platform

SvelteKit is a strong fit for the frontend runtime, routing, and route composition layer. In practice, the web stack should be a Bun-managed TypeScript application that combines SvelteKit for routing and compiled UI delivery, Tailwind CSS for layout and utility styling, and a small set of local stores for session and theming concerns.

That combination is a strong fit for:

• modern reactive UI
• portal and admin functions
• static builds with SPA fallback when SSR is unnecessary
• security-aware frontend behavior
• efficient forms and data-heavy interfaces
• incremental growth from simple public pages toward richer governance workflows

33.3 PostgreSQL and Object Storage as the Base

A robust and practical foundation.

33.4 Event-Driven Side Processes

Useful for:

• search
• notifications
• security scans
• analytics
• webhooks

33.5 Content-Addressed Artifacts

Very important in the long term.

34. Concrete Product Recommendation

If I were to shape this strategically, I would position Publaryn at 1.0 as:

“A secure, organization-ready multi-ecosystem registry for modern software teams, built in Rust, with native support for npm/Bun, PyPI, Cargo, NuGet, Maven, RubyGems, Composer, and OCI.”

That positioning is technically credible, market-relevant, and operationally realistic.

---

35. Summary of the Recommended Target Architecture

Publaryn should:

• have a Rust-based registry core
• use a Bun-managed TypeScript frontend built on SvelteKit and Tailwind CSS
• use PostgreSQL for metadata and governance
• use S3-compatible object storage for artifacts
• run a dedicated search index
• process publish operations through quarantine, validation, and atomic activation
• offer strong organization and permission features
• prioritize secure tokens and OIDC trusted publishing
• make immutable releases a core principle
• use ecosystem-specific protocol adapters instead of forcing a fake universal protocol
• continue the existing public/search/package/auth/settings frontend foundation toward broader governance and administration workflows, starting with dedicated organization workspaces

---

36. Recommended Next Step

The immediate next step is to keep the 1.0 release contract and the codebase in lockstep: every protocol hardening change, security feature, or governance extension should update the README, docs/1.0.md, and the relevant ADR index entry together so the public product contract stays accurate.
