* Bound public rate-limit buckets against attacker-keyed growth. Keep the NIP-13 PoW sender bypass, skip content-bucket minting on sender reject, and evict idle/oldest entries at a hard cap. Co-authored-by: Cursor <cursoragent@cursor.com> * Stop Cashu-looking text from skipping long-message guards. Oversized public content always collapses and takes the plain formatting path so remote tokens cannot force layout/regex DoS. Co-authored-by: Cursor <cursoragent@cursor.com> * Cap teleported geohash participant markers. Bound the set with FIFO eviction, clear it on channel switch, and prune markers that leave the visible participant list. Co-authored-by: Cursor <cursoragent@cursor.com> * Bound untrusted Nostr relay frames and event tags. Reject oversized inbound messages before JSON parse, cap tag arrays/values at decode, and stop logging raw tag contents. Co-authored-by: Cursor <cursoragent@cursor.com> * Fail soft when Noise handshake state is unexpectedly missing. Replace the initiator startHandshake force unwrap with a guard that throws invalidState instead of crashing. Co-authored-by: Cursor <cursoragent@cursor.com> * Cap geohash nickname cache from remote Nostr events. FIFO-evict at capacity, clear on channel switch, and prune nicknames that leave the visible participant list. Co-authored-by: Cursor <cursoragent@cursor.com> * Avoid overlapping exclusive access in the rate limiter. Make bucket helpers static so inout dictionary updates do not conflict with a mutating call on self. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix rate-limiter tests for mutating allow under #expect. Call allow outside the macro so Swift Testing does not capture an immutable copy of the struct. Co-authored-by: Cursor <cursoragent@cursor.com> * Drop unused WebSocket data helper; reset rate limiter on panic wipe. dataWithinInboundLimit replaced the unbounded path, and panic clear should not leave public intake buckets behind.
