BZOD v0.5.1 — Namespace Integrity & Platform Hardening
Release Date: 2026-06-20
BZOD v0.5.1 focuses on platform integrity, multi-tenant safety, dashboard parity, QR reliability, and upgrade validation.
While v0.5.0 introduced the multi-user architecture, v0.5.1 strengthens the foundations required for safe operation at scale.
Highlights
Runtime Efficiency (v0.5.1)
| Metric | Value |
|---|---|
| Binary Size | 11 MB |
| RSS Memory | 11.8 MB |
| Peak RSS | 11.8 MB |
| CPU Idle | 0.02% |
| Swap Usage | 0 KB |
| PIDs | 7 |
On a typical 32 GB server:
- Memory usage: ~0.04%
- No swapping
- Plenty of headroom
BZOD runs closer to a lightweight infrastructure service than a typical web application.
Global Slug Registry
Introduced a hardened global slug registry to guarantee namespace integrity across the entire platform.
The following resources can no longer share the same slug:
- Administrator URLs
- Administrator Landing Pages
- User URLs
- User Landing Pages
Duplicate namespace conflicts are automatically detected and blocked.
Namespace Integrity Validation
New validation routines now verify:
- Duplicate slug detection
- Missing ownership records
- Invalid registry entries
- Invalid target types
- Orphaned slug references
Namespace conflicts now abort upgrades and restores before corruption can occur.
Reservation-Based Slug Allocation
BZOD now reserves slugs before content creation.
Creation workflow:
Quota Check
↓
Reserve Global Slug
↓
Create Content
↓
Activate Slug
↓
Increment Quota
↓
Audit Log
Benefits:
- Prevents race conditions
- Prevents duplicate creation under concurrency
- Enables safer rollback handling
Stale Reservation Recovery
Added automatic cleanup of abandoned slug reservations.
Scenarios covered:
- Server crash during creation
- Interrupted writes
- Failed transactions
BZOD now automatically recovers stale reservations during startup.
Dashboard Parity
Administrator and Standard User dashboards now provide equivalent functionality where appropriate.
Added parity validation for:
- URL management
- Landing page management
- Analytics
- QR code previews
- Export functionality
Differences remain only for administrator-specific operations.
Unified Analytics Templates
Removed duplicated analytics templates.
Benefits:
- Consistent rendering
- Reduced maintenance burden
- Improved reliability
Administrator and user analytics now share the same rendering logic.
QR Code Improvements
QR functionality was substantially improved.
Added
- Inline QR previews
- PNG downloads
- SVG downloads
- Shared QR rendering component
Fixed
- Landing page QR generation
- Multi-user QR ownership handling
- QR routing consistency
- Content-type validation
Canonical Landing Page Routing
Landing page slugs now redirect permanently to canonical page URLs.
Example:
/landing-page
redirects to:
/p/landing-page
using:
301 Moved Permanently
This improves consistency and SEO behavior.
Ownership Isolation Hardening
Additional protections ensure:
- Users cannot access another user's analytics
- Users cannot export another user's data
- Users cannot manage another user's resources
New ownership validation tests were added.
Backup & Restore Improvements
Restore operations now validate namespace integrity before importing data.
Benefits:
- No silent slug collisions
- No partial restores
- No hidden ownership conflicts
Restore operations fail safely when conflicts are detected.
Upgrade Validation Enhancements
Upgrade workflows now verify:
- Global namespace consistency
- Duplicate slug conflicts
- Registry integrity
- Tenant ownership correctness
Unsafe upgrades are blocked automatically.
Health & Diagnostics
The system health subsystem now validates:
- Global slug registry integrity
- Namespace conflicts
- Ownership consistency
- Stale reservations
This improves operational visibility and troubleshooting.
Testing & Validation
BZOD v0.5.1 passed:
- Formatting validation (
cargo fmt --check) - Static analysis (
cargo clippy --all-targets -- -D warnings) - Full automated test suite
- Namespace integrity tests
- Ownership isolation tests
- QR endpoint tests
- Dashboard parity tests
- Upgrade validation tests
- Backup & restore tests
- Disaster recovery tests
- Security tests
- Concurrency tests
All automated tests pass successfully.
Upgrade Notes
Administrators upgrading from v0.5.0 should review:
- UPGRADE.md
- MULTI_USER.md
- BACKUP_RESTORE.md
- DATABASES.md
- TESTING.md
BZOD will automatically validate namespace integrity before completing upgrades.
Duplicate slugs that previously existed across users or resource types must be resolved before migration can proceed.
Breaking Changes
Global Namespace Enforcement
Slugs are now globally unique across the entire platform.
Configurations that previously relied on duplicate slugs across users or resource types will be rejected during upgrade.
This behavior is intentional and protects routing integrity.
Summary
BZOD v0.5.1 is an integrity-focused release that significantly strengthens:
- Namespace safety
- Multi-tenant isolation
- Dashboard consistency
- QR reliability
- Restore safety
- Upgrade safety
- Operational diagnostics
The result is a more predictable, recoverable, and production-ready platform.
