 Read access:
 - **Public hold** (`HOLD_PUBLIC=true`): Anonymous + all authenticated users
-- **Private hold** (`HOLD_PUBLIC=false`): Requires authentication + crew membership with blob:read permission
+- **Private hold** (`HOLD_PUBLIC=false`): Requires authentication + crew membership with blob:read OR blob:write permission
+- **Note:** `blob:write` implicitly grants `blob:read` access (can't push without pulling)
 
 Write access:

+# Analysis: AppView SQL Database Usage
+
+## Overview
+
+The AppView uses SQLite with 19 tables. The key finding: **most data is a cache of ATProto records** that could theoretically be rebuilt from users' PDS instances.
+
+## Data Categories
+
+### 1. MUST PERSIST (Local State Only)
+
+These tables contain data that **cannot be reconstructed** from external sources:
+
+| Table | Purpose | Why It Must Persist |
+|-------|---------|---------------------|
+| `oauth_sessions` | OAuth tokens | Refresh tokens are stateful; losing them = users must re-auth |
+| `ui_sessions` | Web browser sessions | Session continuity for logged-in users |
+| `devices` | Approved devices + bcrypt secrets | User authorization decisions; secrets are one-way hashed |
+| `pending_device_auth` | In-flight auth flows | Short-lived (10min) but critical during auth |
+| `oauth_auth_requests` | OAuth flow state | Short-lived but required for auth completion |
+| `repository_stats` | Pull/push counts | **Locally tracked metrics** - not stored in ATProto |
+
+### 2. CACHED FROM PDS (Rebuildable)
+
+These tables are essentially a **read-through cache** of ATProto data:
+
+| Table | Source | ATProto Collection |
+|-------|--------|-------------------|
+| `users` | User's PDS profile | `app.bsky.actor.profile` + DID document |
+| `manifests` | User's PDS | `io.atcr.manifest` records |
+| `tags` | User's PDS | `io.atcr.tag` records |
+| `layers` | Derived from manifests | Parsed from manifest content |
+| `manifest_references` | Derived from manifest lists | Parsed from multi-arch manifests |
+| `repository_annotations` | Manifest config blob | OCI annotations from config |
+| `repo_pages` | User's PDS | `io.atcr.repo.page` records |
+| `stars` | User's PDS | `io.atcr.sailor.star` records (synced via Jetstream) |
+| `hold_captain_records` | Hold's embedded PDS | `io.atcr.hold.captain` records |
+| `hold_crew_approvals` | Hold's embedded PDS | `io.atcr.hold.crew` records |
+| `hold_crew_denials` | Local authorization cache | Could re-check on demand |
+
+### 3. OPERATIONAL
+
+| Table | Purpose |
+|-------|---------|
+| `schema_migrations` | Migration tracking |
+| `firehose_cursor` | Jetstream position (can restart from 0) |
+
+## Key Insights
+
+### What's Actually Unique to AppView?
+
+1. **Authentication state** - OAuth sessions, devices, UI sessions
+2. **Engagement metrics** - Pull/push counts (locally tracked, not in ATProto)
+
+### What Could Be Eliminated?
+
+If ATCR fully embraced the ATProto model:
+
+1. **`users`** - Query PDS on demand (with caching)
+2. **`manifests`, `tags`, `layers`** - Query PDS on demand (with caching)
+3. **`repository_annotations`** - Fetch manifest config on demand
+4. **`repo_pages`** - Query PDS on demand
+5. **`hold_*` tables** - Query hold's PDS on demand
+
+### Trade-offs
+
+**Current approach (heavy caching):**
+- Fast queries for UI (search, browse, stats)
+- Offline resilience (PDS down doesn't break UI)
+- Complex sync logic (Jetstream consumer, backfill)
+- State can diverge from source of truth
+
+**Lighter approach (query on demand):**
+- Always fresh data
+- Simpler codebase (no sync)
+- Slower queries (network round-trips)
+- Depends on PDS availability
+
+## Current Limitation: No Cache-Miss Queries
+
+**Finding:** There's no "query PDS on cache miss" logic. Users/manifests only enter the DB via:
+1. OAuth login (user authenticates)
+2. Jetstream events (firehose activity)
+
+**Problem:** If someone visits `atcr.io/alice/myapp` before alice is indexed → 404
+
+**Where this happens:**
+- `pkg/appview/handlers/repository.go:50-53`: If `db.GetUserByDID()` returns nil → 404
+- No fallback to `atproto.Client.ListRecords()` or similar
+
+**This matters for Valkey migration:** If cache is ephemeral and restarts clear it, you need cache-miss logic to repopulate on demand. Otherwise:
+- Restart Valkey → all users/manifests gone
+- Wait for Jetstream to re-index OR implement cache-miss queries
+
+**Cache-miss implementation design:**
+
+Existing code to reuse: `pkg/appview/jetstream/processor.go:43-97` (`EnsureUser`)
+
+```go
+// New: pkg/appview/cache/loader.go
+
+type Loader struct {
+    cache  Cache  // Valkey interface
+    client *atproto.Client
+}
+
+// GetUser with cache-miss fallback
+func (l *Loader) GetUser(ctx context.Context, did string) (*User, error) {
+    // 1. Try cache
+    if user := l.cache.GetUser(did); user != nil {
+        return user, nil
+    }
+
+    // 2. Cache miss - resolve identity (already queries network)
+    _, handle, pdsEndpoint, err := atproto.ResolveIdentity(ctx, did)
+    if err != nil {
+        return nil, err  // User doesn't exist in network
+    }
+
+    // 3. Fetch profile for avatar
+    client := atproto.NewClient(pdsEndpoint, "", "")
+    profile, _ := client.GetProfileRecord(ctx, did)
+    avatarURL := ""
+    if profile != nil && profile.Avatar != nil {
+        avatarURL = atproto.BlobCDNURL(did, profile.Avatar.Ref.Link)
+    }
+

+
+**Handler changes:**
+```go
+// Before (repository.go:45-53):
+owner, err := db.GetUserByDID(h.DB, did)
+if owner == nil {
+    RenderNotFound(w, r, h.Templates, h.RegistryURL)
+    return
+}
+
+// After:
+owner, err := h.Loader.GetUser(r.Context(), did)
+if err != nil {
+    RenderNotFound(w, r, h.Templates, h.RegistryURL)
+    return
+}
+```
+
+**Performance considerations:**
+- Cache hit: ~1ms (Valkey lookup)
+- Cache miss: ~200-500ms (PDS round-trip)
+- First request after restart: slower but correct
+- Jetstream still useful for proactive warming
+
+---
+
+## Proposed Architecture: Valkey + ATProto
+
+### Goal
+Replace SQLite with Valkey (Redis-compatible) for ephemeral state, push remaining persistent data to ATProto.
+
+### What goes to Valkey (ephemeral, TTL-based)
+
+| Current Table | Valkey Key Pattern | TTL | Notes |
+|---------------|-------------------|-----|-------|
+| `oauth_sessions` | `oauth:{did}:{session_id}` | 90 days | Lost on restart = re-auth |
+| `ui_sessions` | `ui:{session_id}` | Session duration | Lost on restart = re-login |
+| `oauth_auth_requests` | `authreq:{state}` | 10 min | In-flight flows |
+| `pending_device_auth` | `pending:{device_code}` | 10 min | In-flight flows |
+| `firehose_cursor` | `cursor:jetstream` | None | Can restart from 0 |
+| All PDS cache tables | `cache:{collection}:{did}:{rkey}` | 10-60 min | Query PDS on miss |
+
+**Benefits:**
+- Multi-instance ready (shared Valkey)
+- No schema migrations
+- Natural TTL expiry
+- Simpler code (no SQL)
+
+### What could become ATProto records
+
+| Current Table | Proposed Collection | Where Stored | Open Questions |
+|---------------|---------------------|--------------|----------------|
+| `devices` | `io.atcr.sailor.device` | User's PDS | Privacy: IP, user-agent sensitive? |
+| `repository_stats` | `io.atcr.repo.stats` | Hold's PDS or User's PDS | Who owns the stats? |
+
+**Devices → Valkey:**
+- Move current device table to Valkey
+- Key: `device:{did}:{device_id}` → `{name, secret_hash, ip, user_agent, created_at, last_used}`
+- TTL: Long (1 year?) or no expiry
+- Device list: `devices:{did}` → Set of device IDs
+- Secret validation works the same, just different backend
+
+**Service auth exploration (future):**
+The challenge with pure ATProto service auth is the AppView still needs the user's OAuth session to write manifests to their PDS. The current flow:
+1. User authenticates via OAuth → AppView gets OAuth tokens
+2. AppView issues registry JWT to credential helper
+3. Credential helper presents JWT on each push/pull
+4. AppView uses OAuth session to write to user's PDS
+
+Service auth could work for the hold side (AppView → Hold), but not for the user's OAuth session.
+
+**Repository stats → Hold's PDS:**
+
+**Challenge discovered:** The hold's `getBlob` endpoint only receives `did` + `cid`, not the repository name.
+
+Current flow (`proxy_blob_store.go:358-362`):
+```go
+xrpcURL := fmt.Sprintf("%s%s?did=%s&cid=%s&method=%s",
+    p.holdURL, atproto.SyncGetBlob, p.ctx.DID, dgst.String(), operation)
+```
+
+**Implementation options:**
+
+**Option A: Add repository parameter to getBlob (recommended)**
+```go
+// Modified AppView call:
+xrpcURL := fmt.Sprintf("%s%s?did=%s&cid=%s&method=%s&repo=%s",
+    p.holdURL, atproto.SyncGetBlob, p.ctx.DID, dgst.String(), operation, p.ctx.Repository)
+```
+
+```go
+// Modified hold handler (xrpc.go:969):
+func (h *XRPCHandler) HandleGetBlob(w http.ResponseWriter, r *http.Request) {
+    did := r.URL.Query().Get("did")
+    cidOrDigest := r.URL.Query().Get("cid")
+    repo := r.URL.Query().Get("repo")  // NEW
+
+    // ... existing blob handling ...
+
+    // Increment stats if repo provided
+    if repo != "" {
+        go h.pds.IncrementPullCount(did, repo)  // Async, non-blocking
+    }
+}
+```
+
+**Stats record structure:**
+```
+Collection: io.atcr.hold.stats
+Rkey: base64(did:repository)  // Deterministic, unique
+
+{
+  "$type": "io.atcr.hold.stats",
+  "did": "did:plc:alice123",
+  "repository": "myapp",
+  "pullCount": 1542,
+  "pushCount": 47,
+  "lastPull": "2025-01-15T...",
+  "lastPush": "2025-01-10T...",
+  "createdAt": "2025-01-01T..."
+}
+```
+
+**Hold-side implementation:**
+```go
+// New file: pkg/hold/pds/stats.go
+
+func (p *HoldPDS) IncrementPullCount(ctx context.Context, did, repo string) error {
+    rkey := statsRecordKey(did, repo)
+
+    // Get or create stats record
+    stats, err := p.GetStatsRecord(ctx, rkey)
+    if err != nil || stats == nil {
+        stats = &atproto.StatsRecord{
+            Type:       atproto.StatsCollection,
+            DID:        did,
+            Repository: repo,
+            PullCount:  0,
+            PushCount:  0,
+            CreatedAt:  time.Now(),
+        }
+    }
+
+    // Increment and update
+    stats.PullCount++
+    stats.LastPull = time.Now()
+
+    _, err = p.repomgr.UpdateRecord(ctx, p.uid, atproto.StatsCollection, rkey, stats)
+    return err
+}
+```
+
+**Query endpoint (new XRPC):**
+```
+GET /xrpc/io.atcr.hold.getStats?did={userDID}&repo={repository}
+→ Returns JSON: { pullCount, pushCount, lastPull, lastPush }
+
+GET /xrpc/io.atcr.hold.listStats?did={userDID}
+→ Returns all stats for a user across all repos on this hold
+```
+
+**AppView aggregation:**
+```go
+func (l *Loader) GetAggregatedStats(ctx context.Context, did, repo string) (*Stats, error) {
+    // 1. Get all holds that have served this repo
+    holdDIDs, _ := l.cache.GetHoldDIDsForRepo(did, repo)
+
+    // 2. Query each hold for stats
+    var total Stats
+    for _, holdDID := range holdDIDs {
+        holdURL := resolveHoldDID(holdDID)
+        stats, _ := queryHoldStats(ctx, holdURL, did, repo)
+        total.PullCount += stats.PullCount
+        total.PushCount += stats.PushCount
+    }
+
+    return &total, nil
+}
+```
+
+**Files to modify:**
+- `pkg/atproto/lexicon.go` - Add `StatsCollection` + `StatsRecord`
+- `pkg/hold/pds/stats.go` - New file for stats operations
+- `pkg/hold/pds/xrpc.go` - Add `repo` param to getBlob, add stats endpoints
+- `pkg/appview/storage/proxy_blob_store.go` - Pass repository to getBlob
+- `pkg/appview/cache/loader.go` - Aggregation logic
+
+### Migration Path
+
+**Phase 1: Add Valkey infrastructure**
+- Add Valkey client to AppView
+- Create store interfaces that abstract SQLite vs Valkey
+- Dual-write OAuth sessions to both
+
+**Phase 2: Migrate sessions to Valkey**
+- OAuth sessions, UI sessions, auth requests, pending device auth
+- Remove SQLite session tables
+- Test: restart AppView, users get logged out (acceptable)
+
+**Phase 3: Migrate devices to Valkey**
+- Move device store to Valkey
+- Same data structure, different backend
+- Consider device expiry policy
+
+**Phase 4: Implement hold-side stats**
+- Add `io.atcr.hold.stats` collection to hold's embedded PDS
+- Hold increments stats on blob access
+- Add XRPC endpoint: `io.atcr.hold.getStats`
+
+**Phase 5: AppView stats aggregation**
+- Track holdDids per repo in Valkey cache
+- Query holds for stats, aggregate
+- Cache aggregated stats with TTL
+
+**Phase 6: Remove SQLite (optional)**
+- Keep SQLite as optional cache layer for UI queries
+- Or: Query PDS on demand with Valkey caching
+- Jetstream still useful for real-time updates
+
+## Summary Table
+
+| Category | Tables | % of Schema | Truly Persistent? |
+|----------|--------|-------------|-------------------|
+| Auth & Sessions + Metrics | 6 | 32% | Yes |
+| PDS Cache | 11 | 58% | No (rebuildable) |
+| Operational | 2 | 10% | No |
+
+**~58% of the database is cached ATProto data that could be rebuilt from PDSes.**
