       ### Token Refresh Logic for Community Credentials

       ### ✅ Token Refresh Logic for Community Credentials - COMPLETE

     

       53
       53
       +
       **Added:** 2025-10-11 | **Completed:** 2025-10-17 | **Effort:** 1.5 days | **Status:** ✅ DONE

     

       54
       54
        
       

     

       55
       55
        
       **Problem:** Community PDS access tokens expire (~2hrs). Updates fail until manual intervention.

     

       56
       56
        
       

     

       57
       57
       -
       **Solution:** Auto-refresh tokens before PDS operations. Parse JWT exp claim, use refresh token when expired, update DB.

     

       57
       57
       +
       **Solution Implemented:**

     

       58
       58
       +
       - ✅ Automatic token refresh before PDS operations (5-minute buffer before expiration)

     

       59
       59
       +
       - ✅ JWT expiration parsing without signature verification (`parseJWTExpiration`, `needsRefresh`)

     

       60
       60
       +
       - ✅ Token refresh using Indigo SDK (`atproto.ServerRefreshSession`)

     

       61
       61
       +
       - ✅ Password fallback when refresh tokens expire (~2 months) via `atproto.ServerCreateSession`

     

       62
       62
       +
       - ✅ Atomic credential updates (`UpdateCredentials` repository method)

     

       63
       63
       +
       - ✅ Concurrency-safe with per-community mutex locking

     

       64
       64
       +
       - ✅ Structured logging for monitoring (`[TOKEN-REFRESH]` events)

     

       65
       65
       +
       - ✅ Integration tests for token expiration detection and credential updates

       ### Cross-PDS Write-Forward Support

     

       138
       138
       +
       **Added:** 2025-10-17 | **Effort:** 3-4 hours | **Priority:** FEDERATION BLOCKER (Beta)

     

       139
       139
       +
       

     

       140
       140
       +
       **Problem:** Current write-forward implementation assumes all users are on the same PDS as the Coves instance. This breaks federation when users from external PDSs try to interact with communities.

     

       141
       141
       +
       

     

       142
       142
       +
       **Current Behavior:**

     

       143
       143
       +
       - User on `pds.bsky.social` subscribes to community on `coves.social`

     

       144
       144
       +
       - Coves calls `s.pdsURL` (instance default: `http://localhost:3001`)

     

       145
       145
       +
       - Write goes to WRONG PDS → fails with 401/403

     

       146
       146
       +
       

     

       147
       147
       +
       **Impact:**

     

       148
       148
       +
       - ✅ **Alpha**: Works fine (single PDS deployment)

     

       149
       149
       +
       - ❌ **Beta**: Breaks federation (users on different PDSs can't subscribe/interact)

     

       150
       150
       +
       

     

       151
       151
       +
       **Root Cause:**

     

       152
       152
       +
       - [service.go:736](../internal/core/communities/service.go#L736): `createRecordOnPDSAs` hardcodes `s.pdsURL`

     

       153
       153
       +
       - [service.go:753](../internal/core/communities/service.go#L753): `putRecordOnPDSAs` hardcodes `s.pdsURL`

     

       154
       154
       +
       - [service.go:767](../internal/core/communities/service.go#L767): `deleteRecordOnPDSAs` hardcodes `s.pdsURL`

     

       155
       155
       +
       

     

       156
       156
       +
       **Solution:**

     

       157
       157
       +
       1. Add identity resolver dependency to `CommunityService`

     

       158
       158
       +
       2. Before write-forward, resolve user's DID → extract PDS URL

     

       159
       159
       +
       3. Call user's actual PDS instead of `s.pdsURL`

     

       160
       160
       +
       

     

       161
       161
       +
       **Implementation:**

     

       162
       162
       +
       ```go

     

       163
       163
       +
       // Before write-forward to user's repo:

     

       164
       164
       +
       userIdentity, err := s.identityResolver.ResolveDID(ctx, userDID)

     

       165
       165
       +
       if err != nil {

     

       166
       166
       +
           return fmt.Errorf("failed to resolve user PDS: %w", err)

     

       167
       167
       +
       }

     

       168
       168
       +
       

     

       169
       169
       +
       // Use user's actual PDS URL

     

       170
       170
       +
       endpoint := fmt.Sprintf("%s/xrpc/com.atproto.repo.createRecord", userIdentity.PDSURL)

     

       171
       171
       +
       ```

     

       172
       172
       +
       

     

       173
       173
       +
       **Files to Modify:**

     

       174
       174
       +
       - `internal/core/communities/service.go` - Add resolver, modify write-forward methods

     

       175
       175
       +
       - `cmd/server/main.go` - Pass identity resolver to community service constructor

     

       176
       176
       +
       - Tests - Add cross-PDS scenarios

       178
       178
       +
       **Testing:**

     

       179
       179
       +
       - User on external PDS subscribes to community

     

       180
       180
       +
       - User on external PDS blocks community

     

       181
       181
       +
       - Community updates still work (communities ARE on instance PDS)

       ### Core Infrastructure

     

       39
       39
        
       - [x] **V2 Architecture:** Communities own their own repositories

     

       40
       40
        
       - [x] **PDS Account Provisioning:** Automatic account creation for each community

     

       41
       41
        
       - [x] **Credential Management:** Secure storage of community PDS credentials

     

       42
       42
       +
       - [x] **Token Refresh:** Automatic refresh of expired access tokens (completed 2025-10-17)

     

       42
       43
        
       - [x] **Encryption at Rest:** PostgreSQL pgcrypto for sensitive credentials

     

       43
       44
        
       - [x] **Write-Forward Pattern:** Service → PDS → Firehose → AppView

     

       44
       45
        
       - [x] **Jetstream Consumer:** Real-time indexing from firehose

       ### Security & Data Protection

     

       48
       49
        
       - [x] **Encrypted Credentials:** Access/refresh tokens encrypted in database

     

       49
       50
        
       - [x] **Credential Persistence:** PDS credentials survive server restarts

     

       51
       51
       +
       - [x] **Automatic Token Refresh:** Tokens refresh 5 minutes before expiration (completed 2025-10-17)

       50
       54
        
       - [x] **JSON Exclusion:** Credentials never exposed in API responses (`json:"-"` tags)

     

       51
       51
       -
       - [x] **Password Hashing:** bcrypt for PDS account passwords
