+# Five turns retain one referent across fact, query and chat routes
+
+Measured 2026-08-13 on homesrv from `master` at `a0e6643` plus the V-542
+working tree. Task: V-542. The run uses the deterministic simulator phraser;
+no resident model is needed.
+
+## Setup
+
+`conversation_anaphora.json` replays the five Russian turns that exposed the
+defect. Their scripted router decisions remain the observed
+fact/query/query/chat/query sequence. Each of the four contextual replies is
+accepted only if the chat phraser receives history containing the original
+`купил новый монитор` turn; this prevents a canned response from hiding a
+missing transcript.
+
+Commands:
+
+```sh
+make t PKG=./cmd/mavend RUN='TestExplicitConversationOpenerKeepsCrossIntentSessionAlive|TestConversationOpenerDoesNotMatchAnotherDavaiCommand|TestFollowUpMerge|TestSimulatorScenarios/conversation_anaphora' V=1 RACE=1
+make t PKG=./internal/dialogue RUN=TestSessionSurvivesRestart V=1 RACE=1
+make t PKG=./internal/router RUN=TestAnaphoraResolverUsesTokenBoundariesAcrossPunctuation V=1 RACE=1
+MAVEN_DIALOGUE_NO_SKIP=1 make t PKG=./cmd/mavend RUN=TestDialogueTraces V=1 RACE=0
+```
+
+## Result
+
+| Gate | before | after |
+| --- | ---: | ---: |
+| contextual replies that name the monitor | 0/4 | **4/4** |
+| replies proven to receive the original turn in history | 0/4 | **4/4** |
+| original grounded fact still written | 1/1 | **1/1** |
+| unsolicited sends in five turns plus one tick | 0/6 | **0/6** |
+| focused race-tested packages | — | **3/3 pass** |
+
+The forced dialogue suite passed 18/22 rows. Its four failures are the existing,
+unrelated offline-floor cases for a mid-flow note, a correction while a question
+is parked, a whole-day reminder, and a short correction that does not park a
+clarification. None exercises V-542; the continuity scenario and all focused
+race gates pass.
+
+## What this rules out
+
+The fix does not rewrite pronouns into guessed nouns or add a phrase regex.
+Exact utterances form a persisted, chronological transcript independently of
+intent slots. An anaphoric query with live dialogue context moves to chat and
+clears query-source provenance; non-anaphoric queries retain their source path,
+and acts are never widened. An explicit conversation opener extends session
+lifetime without suppressing the fact side effect in its substantive clause.
