Fix rate limiting: exempt health/metrics, increase upload limits

- Health, metrics, UI, and API docs are now exempt from rate limiting
- Increased upload rate limits to 200 req/s with burst of 500 for Docker compatibility

+
+## v0.3.0 - OIDC / Workload Identity Federation
+
+### Killer Feature: OIDC for CI/CD
+Zero-secret authentication for GitHub Actions, GitLab CI, etc.
+
+**Goal:** Replace manual `ROBOT_TOKEN` rotation with federated identity.
+
+```yaml
+# GitHub Actions example
+permissions:
+  id-token: write
+steps:
+  - name: Login to NORA
+    uses: nora/login-action@v1
+```
+
+### Config Structure (draft)
+
+```toml
+[auth.oidc]
+enabled = true
+
+# GitHub Actions
+[[auth.oidc.providers]]
+name = "github-actions"
+issuer = "https://token.actions.githubusercontent.com"
+audience = "https://nora.example.com"
+
+[[auth.oidc.providers.rules]]
+# Claim matching (supports glob)
+match = { repository = "my-org/*", ref = "refs/heads/main" }
+# Granted permissions
+permissions = ["push:my-org/*", "pull:*"]
+
+[[auth.oidc.providers.rules]]
+match = { repository = "my-org/*", ref = "refs/heads/*" }
+permissions = ["pull:*"]
+
+# GitLab CI
+[[auth.oidc.providers]]
+name = "gitlab-ci"
+issuer = "https://gitlab.com"
+audience = "https://nora.example.com"
+
+[[auth.oidc.providers.rules]]
+match = { project_path = "my-group/*" }
+permissions = ["push:my-group/*", "pull:*"]
+```
+
+### Implementation Tasks
+- [ ] JWT validation library (jsonwebtoken crate)
+- [ ] OIDC discovery (/.well-known/openid-configuration)
+- [ ] JWKS fetching and caching
+- [ ] Claims extraction and glob matching
+- [ ] Permission resolution from rules
+- [ ] Token exchange endpoint (POST /auth/oidc/token)
+- [ ] GitHub Action: `nora/login-action`
+
+---
+
+## v0.4.0 - Transparent Docker Hub Proxy
+
+### Pain Point
+Harbor forces tag changes: `docker pull my-harbor/proxy-cache/library/nginx`
+This breaks Helm charts hardcoded to `nginx`.
+
+### Goal
+Transparent pull-through cache:
+```bash
+docker pull nora.example.com/nginx  # -> proxies to Docker Hub
+```
+
+### Implementation Tasks
+- [ ] Registry v2 API interception
+- [ ] Upstream registry configuration
+- [ ] Cache layer management
+- [ ] Rate limit handling (Docker Hub limits)
+
+---
+
+## v0.5.0 - Repo-level RBAC
+
+### Challenge
+Per-repository permissions need fast lookup (100 layers per push).
+
+### Solution
+Glob patterns for 90% of cases:
+```toml
+[[auth.rules]]
+subject = "team-frontend"
+permissions = ["push:frontend/*", "pull:*"]
+
+[[auth.rules]]
+subject = "ci-bot"
+permissions = ["push:*/release-*", "pull:*"]
+```
+
+### Implementation Tasks
+- [ ] In-memory permission cache
+- [ ] Glob pattern matcher (globset crate)
+- [ ] Permission inheritance (org -> project -> repo)
+
+---
+
+## Target Audience
+
+1. DevOps engineers tired of Java/Go monsters
+2. Edge/IoT installations (Raspberry Pi, branch offices)
+3. Educational platforms (student labs)
+4. CI/CD pipelines (GitHub Actions, GitLab CI)
+
+## Competitive Advantages
+
+| Feature | NORA | Harbor | Nexus |
+|---------|------|--------|-------|
+| Memory | <100MB | 2GB+ | 4GB+ |
+| OIDC for CI | v0.3.0 | No | No |
+| Transparent proxy | v0.4.0 | No (tag rewrite) | Partial |
+| Single binary | Yes | No (microservices) | No (Java) |
+| Zero-config upgrade | Yes | Complex | Complex |
+
+---
+
+## v0.6.0 - Online Garbage Collection
+
+### Pain Point
+Harbor GC blocks registry for hours. Can't push during cleanup.
+
+### Goal
+Non-blocking garbage collection with zero downtime.
+
+### Implementation Tasks
+- [ ] Mark-and-sweep without locking
+- [ ] Background blob cleanup
+- [ ] Progress reporting via API/CLI
+- [ ] `nora gc --dry-run` preview
+
+---
+
+## v0.7.0 - Retention Policies
+
+### Pain Point
+"Keep last 10 tags" sounds simple, works poorly everywhere.
+
+### Goal
+Declarative retention rules in config:
+
+```toml
+[[retention]]
+match = "*/dev-*"
+keep_last = 5
+
+[[retention]]
+match = "*/release-*"
+keep_last = 20
+older_than = "90d"
+
+[[retention]]
+match = "**/pr-*"
+older_than = "7d"
+```
+
+### Implementation Tasks
+- [ ] Glob pattern matching for repos/tags
+- [ ] Age-based and count-based rules
+- [ ] Dry-run mode
+- [ ] Scheduled execution (cron-style)
+
+---
+
+## v0.8.0 - Multi-tenancy & Quotas
+
+### Pain Point
+Harbor projects have quotas but configuration is painful. Nexus has no real isolation.
+
+### Goal
+Simple namespaces with limits:
+
+```toml
+[[tenants]]
+name = "team-frontend"
+storage_quota = "50GB"
+rate_limit = { push = 100, pull = 1000 }  # per hour
+
+[[tenants]]
+name = "team-backend"
+storage_quota = "100GB"
+```
+
+### Implementation Tasks
+- [ ] Tenant isolation (namespace prefix)
+- [ ] Storage quota tracking
+- [ ] Per-tenant rate limiting
+- [ ] Usage reporting API
+
+---
+
+## v0.9.0 - Smart Replication
+
+### Pain Point
+Harbor replication rules are complex, errors silently swallowed.
+
+### Goal
+Simple CLI-driven replication with clear feedback:
+
+```bash
+nora replicate --to remote-dc --filter "prod/*" --dry-run
+nora replicate --from gcr.io/my-project/* --to local/imported/
+```
+
+### Implementation Tasks
+- [ ] Push-based replication to remote NORA
+- [ ] Pull-based import from external registries (Docker Hub, GCR, ECR, Quay)
+- [ ] Filter by glob patterns
+- [ ] Progress bar and detailed logs
+- [ ] Retry logic with exponential backoff
+
+---
+
+## v1.0.0 - Production Ready
+
+### Features to polish
+- [ ] Full CLI (`nora images ls`, `nora tag`, `nora delete`)
+- [ ] Webhooks with filters and retry logic
+- [ ] Enhanced Prometheus metrics (per-repo stats, cache hit ratio, bandwidth per tenant)
+- [ ] TUI dashboard (optional)
+- [ ] Helm chart for Kubernetes deployment
+- [ ] Official Docker image on ghcr.io
+
+---
+
+## Future Ideas (v1.x+)
+
+### Cold Storage Tiering
+Auto-move old tags to S3 Glacier:
+```toml
+[[storage.tiering]]
+match = "*"
+older_than = "180d"
+move_to = "s3-glacier"
+```
+
+### Vulnerability Scanning Integration
+Not built-in (use Trivy), but:
+- [ ] Webhook on push -> trigger external scan
+- [ ] Store scan results as OCI artifacts
+- [ ] Block pull if critical CVEs (policy)
+
+### Image Signing (Cosign/Notation)
+- [ ] Signature storage (OCI artifacts)
+- [ ] Policy enforcement (reject unsigned)
+
+### P2P Distribution (Dragonfly/Kraken style)
+For large clusters pulling same image simultaneously.
+
+---
+

+
+#### Key Principles
+
+1. **Hexagonal Architecture**
+   - Core domain has no external dependencies
+   - Ports (traits) define boundaries
+   - Adapters implement ports (S3, filesystem, OIDC providers)
+
+2. **Event-Driven**
+   - Domain events: `ArtifactPushed`, `ArtifactDeleted`, `TagCreated`
+   - Webhooks subscribe to events
+   - Async processing for GC, replication
+
+3. **CQRS-lite**
+   - Commands: Push, Delete, CreateToken
+   - Queries: List, Get, Search
+   - Separate read/write paths for hot endpoints
+
+4. **Configuration as Code**
+   - All policies in `nora.toml`
+   - No database for config (file-based)
+   - GitOps friendly
+
+#### Trait Boundaries (Ports)
+
+```rust
+// nora-core/src/ports.rs
+
+#[async_trait]
+pub trait ArtifactStore {
+    async fn push_blob(&self, digest: &Digest, data: Bytes) -> Result<()>;
+    async fn get_blob(&self, digest: &Digest) -> Result<Bytes>;
+    async fn push_manifest(&self, repo: &Repository, tag: &Tag, manifest: &Manifest) -> Result<()>;
+    async fn get_manifest(&self, repo: &Repository, reference: &Reference) -> Result<Manifest>;
+    async fn list_tags(&self, repo: &Repository) -> Result<Vec<Tag>>;
+    async fn delete(&self, repo: &Repository, reference: &Reference) -> Result<()>;
+}
+
+#[async_trait]
+pub trait IdentityProvider {
+    async fn authenticate(&self, credentials: &Credentials) -> Result<Identity>;
+    async fn authorize(&self, identity: &Identity, action: &Action, resource: &Resource) -> Result<bool>;
+}
+
+#[async_trait]
+pub trait EventPublisher {
+    async fn publish(&self, event: DomainEvent) -> Result<()>;
+}
+```
+
+#### Migration Path
+
+| Phase | Action |
+|-------|--------|
+| v0.3 | Extract `nora-auth` crate (OIDC work) |
+| v0.4 | Extract `nora-core` domain types |
+| v0.5 | Extract `nora-storage` with trait boundaries |
+| v0.6+ | Refactor registry handlers to use ports |
+| v1.0 | Full hexagonal architecture |
+
+### Technical Debt to Address
+
+- [ ] Remove `unwrap()` in non-test code (started in e9984cf)
+- [ ] Add tracing spans to all handlers
+- [ ] Consistent error types across modules
+- [ ] Extract hardcoded limits to config
+- [ ] Add OpenTelemetry support (traces, not just metrics)
+
+### Performance Requirements
+
+| Metric | Target |
+|--------|--------|
+| Memory (idle) | <50MB |
+| Memory (under load) | <100MB |
+| Startup time | <1s |
+| Blob throughput | Wire speed (no processing overhead) |
+| Manifest latency | <10ms p99 |
+| Auth check | <1ms (cached) |
+
+### Security Requirements
+
+- [ ] No secrets in logs (already redacting)
+- [ ] TLS termination (or trust reverse proxy)
+- [ ] Content-addressable storage (immutable blobs)
+- [ ] Audit log for all mutations
+- [ ] SBOM generation for NORA itself
+
+---
+
+## Notes
+
+- S3 storage: already implemented
+- Web UI: minimalist read-only dashboard (done)
+- TUI: consider for v1.0
+- Vulnerability scanning: out of scope (use Trivy externally)
+- Image signing: out of scope for now (use cosign externally)
