Subscription Goroutines + +Each active subscription runs a goroutine that receives events from the publisher and forwards them in [`app/handle-req.go:696-736`](../../app/handle-req.go#L696-L736): + +```go +// Subscription goroutine (one per REQ) +go func() { + for { + select { + case ev := <-evC: // Receive from publisher + res := eventenvelope.NewFrom(subID, ev) + if err = res.Write(l); err != nil { // ← Sends to writeChan + log.E.F("failed to write event") + } + } + } +}() +``` + +#### C.

Read Access Uses OR Logic +**Problem**: When both `read_allow` and `privileged` were set, the allow list was overriding privileged access, blocking involved parties. + +**Solution**: Implemented OR logic for read access - users can read if they are: +- In the `read_allow` list, OR +- Involved in a privileged event (author or p-tagged) + +### 4. Implicit Kind Whitelist +**Problem**: All kinds were allowed by default even when specific rules existed. + +**Solution**: Kinds with defined rules are now implicitly whitelisted.

Documentation files in `/docs/` - Comprehensive documentation + +## Result + +The policy system now provides: +- **Secure by default**: Authentication required for all operations +- **Predictable behavior**: Clear evaluation order and precedence rules +- **Flexible access control**: OR logic for read access, exclusive write control +- **Automatic kind filtering**: Implicit whitelist based on rule presence +- **Performance optimized**: Binary cache for fast pubkey comparisons +- **Fully tested**: All requirements verified with comprehensive test coverage + +All 5 requirements from Issue #5 are now correctly implemented and verified. \ No newline at end of file
