 ## [Unreleased]
 
+### Added
+- DialogueResponse verb handler — players pick dialogue options and receive follow-up lines via full D-028 four-layer pipeline (#539)
+- Trust-gated gossip verification — integration tests confirm Secret/Real/Surface tier gating per D-075 (#171)
+- Line variety tracker wiring — DialogueCooldownTracker prevents repeat lines within 600-tick window (#338)
+- DialogueResponse cross-language fixture for GDScript testing
+- Sprint team lifecycle through PR review — teams stay alive for commit → push → review → fix loop → approve → shutdown
+
+### Fixed
+- Dialogue systems moved from BridgePlugin to NpcPlugin — game logic registers where it belongs (#538)
+- Schedule ambiguity: emit_observation_events now has explicit .before(advance_tick) constraint
+- process_dialogue_response updates ActiveDialogue tick and InteractionMemory on follow-up
+- DialogueResponse range check added (CLOSE_RANGE, matching Talk/Confront pattern)
+- Weighted selection fallback replaced with unreachable!() — dead code removed
+- assert!(false) → panic!() in serialization tests (clippy)
+- SetFacing and TeleportToHub added to roundtrip test coverage
+
+### Changed
+- Shared run_dialogue_pipeline() helper eliminates ~60 lines of duplication between Talk and DialogueResponse systems
+- DialogueCooldownTracker documented as per-player-global by design (NPC-scoped line IDs per D-035 prevent collision)
+- CONFRONTATION_LINES marked TODO for migration to D-028/D-035 content pipeline
+- pr-push and pr-review skills updated with team lifecycle awareness
+
