Issue / Design

Closes #887 — Phase 9 r1 consensus(unanimous):room-actor-authority-delete-singleton

#874 follow-up:#874 reuse StreamingProxyGAgent 作 authority,但 singleton + dual store 仍存。本 PR 真清理。

改动

删除 dual fact source:

  • StreamingProxyParticipantGAgent(singleton cluster-scoped actor)
  • streaming_proxy_participant_messages.proto + State
  • Projection/StreamingProxyParticipantProjector + StreamingProxyParticipantCurrentStateDocument
  • projection readmodel registration + cluster-scoped 启动注册
  • ActorBackedStreamingProxyParticipantStore(dual-write surface)
  • IStreamingProxyParticipantStore 应用层 surface

保留/重做:

#885 协调

#885StreamingProxyNyxParticipantCoordinator(facade);本 PR 不动。merge 顺序:#874 已 merged → #885 待 → 本 PR(独立)。

验证

  • dotnet test ... StreamingProxy PASS(72)
  • dotnet test ... ActorBacked / StoreAdapter / StudioProjection PASS(141)
  • bash tools/ci/test_stability_guards.sh PASS
  • bash tools/ci/query_projection_priming_guard.sh / projection_state_version_guard.sh / projection_state_mirror_current_state_guard.sh / projection_route_mapping_guard.sh PASS
  • bash tools/docs/lint.sh PASS

净改动

31 files +399/-1235(净 -836 LOC,真删除而非空壳)。

Blocking: #893 is not conflict-free with #885. A no-worktree `git merge-tree` between `origin/pr-885` and `origin/pr-893` shows conflicts in [ServiceCollectionExtensions.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/ServiceCollectionExtensions.cs:32), [StreamingProxyEndpoints.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/StreamingProxyEndpoints.cs:163), [StreamingProxyGAgent.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/StreamingProxyGAgent.cs:167), coordinator, proto, and tests. #885 introduces lifecycle facade/actor outcome handling on the same endpoint and composition surface; #893’s current endpoint path still composes directly around `IStreamingProxyRoomCommandService` + interaction service. This fails the requested “#885 边界不冲突” review gate.

What passed architecturally inside #893 itself: singleton participant actor/store/readmodel deletion is clean; participant writes now go to room actor events; reads use room current-state projection; no old store/readmodel production references remain. Projection uses committed room state and `stateEvent.Version`, not a local version.

Verification run:
`dotnet test test/Aevatar.AI.Tests/Aevatar.AI.Tests.csproj --no-restore --filter "FullyQualifiedName~StreamingProxy" --nologo` passed 72.
`dotnet test test/Aevatar.Tools.Cli.Tests/Aevatar.Tools.Cli.Tests.csproj --no-restore --filter ...` passed 141.
Projection/query guards and test stability guard passed.
GitHub CI still had `coverage-quality` in progress when checked.

**Findings**

1. **Reject: StreamingProxy participant readmodel has no activation path.**  
   [ServiceCollectionExtensions.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/ServiceCollectionExtensions.cs:59) registers the current-state materialization runtime and [StreamingProxyRoomParticipantsProjector](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/StreamingProxyRoomParticipantsProjector.cs:23), but `rg` finds no `CommittedStateProjectionActivationHook`, `ProjectionActivationPlanDispatcher`, or `IProjectionActivationPlanProvider` registration/provider under `agents/Aevatar.GAgents.StreamingProxy` or its tests. That means committed room participant events can be stored/published while the new `StreamingProxyRoomParticipantsSnapshot` never gets materialized in the normal path. The endpoint then reads an empty/null snapshot via [StreamingProxyRoomParticipantService.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/Application/Rooms/StreamingProxyRoomParticipantService.cs:23), so the new single-authority read path is not actually live.

2. **Reject: stale/cold participant projection leaks into write control flow.**  
   `EnsureNyxParticipantsJoinedAsync` dedupes by reading the projection at [StreamingProxyRoomParticipantService.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/Application/Rooms/StreamingProxyRoomParticipantService.cs:52), then dispatches joins for missing ids at [StreamingProxyNyxParticipantCoordinator.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/StreamingProxyNyxParticipantCoordinator.cs:57). The room actor persists every join before state transition at [StreamingProxyGAgent.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/StreamingProxyGAgent.cs:67), while dedupe only happens in the state applier at [StreamingProxyGAgent.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/agents/Aevatar.GAgents.StreamingProxy/StreamingProxyGAgent.cs:162). With a cold or eventually stale readmodel, repeated chats can commit and broadcast duplicate “joined” facts. The room actor owns current participants, but not the idempotent join decision.

CI is not merge-ready yet: `coverage-quality` is still pending, so the requested “CI green” condition is also unmet.

📊 状态 — r1 2/3 reject → fix-r2 dispatch

r1: tests APPROVE / architect REJECT / quality REJECT。2 同根 BLOCKER:

  1. Participant readmodel 无 projection activation path — committed events 存了但不被物化,endpoint 读空 snapshot,新 authority 读路径不 live
  2. Cold/stale projection 漏入 write control flow — service 层 dedupe 读 stale readmodel → 反复 commit broadcast 重复 joined facts(actor owns participants 但 idempotent join decision 不在 actor 内)

派 fix-r2:加 activation provider(参考 #882 pattern)+ dedupe 决策移入 actor 内部。

Implemented within `agents/Aevatar.GAgents.StreamingProxy/` only.

Changes:
- Added `StreamingProxyCommittedStateProjectionActivationPlanProvider` and DI registration for `ProjectionActivationPlanDispatcher`, `CommittedStateProjectionActivationHook`, and the provider.
- Removed service-layer readmodel-based join dedupe from `StreamingProxyRoomParticipantService`.
- Moved idempotent participant join decision into `StreamingProxyGAgent` before persisting/broadcasting joined facts.
- Coordinator now dispatches join commands without consulting stale/cold projection state.

Verification:
- `dotnet build agents/Aevatar.GAgents.StreamingProxy/Aevatar.GAgents.StreamingProxy.csproj --nologo` passed.
- `bash tools/ci/architecture_guards.sh` passed.
- Projection guard scripts passed.

No blocking findings.

The r2 reject gap is genuinely covered in r3. `3a7dfc3f` adds [StreamingProxyCommittedStateProjectionActivationPlanProviderTests.cs](/Users/auric/aevatar-wt-iter50-cluster-050-streaming-proxy-participant-authority/test/Aevatar.AI.Tests/StreamingProxyCommittedStateProjectionActivationPlanProviderTests.cs:20), with:

- provider plan mapping across 6 room committed-state event types
- DI registration assertions for dispatcher, hook, provider, and activation service
- real local actor runtime path: committed participant event -> activation -> materializer -> readmodel upsert

Verification run:
`dotnet test test/Aevatar.AI.Tests/Aevatar.AI.Tests.csproj --no-restore --filter FullyQualifiedName~StreamingProxyCommittedStateProjectionActivationPlanProviderTests --nologo` passed 8/8.

Guards also passed: `test_stability`, `query_projection_priming`, `projection_state_version`, `projection_state_mirror_current_state`, `projection_route_mapping`.

…实源,删 singleton + dual store + readmodel

design consensus(Phase 9 r1 unanimous,#887):room-actor-authority-delete-singleton。

删除:
- StreamingProxyParticipantGAgent(singleton cluster-scoped actor)
- streaming_proxy_participant_messages.proto + State
- Projection/projector + studio_projection_readmodels.proto 内 StreamingProxyParticipantCurrentStateDocument
- projection readmodel registration + cluster-scoped 启动注册
- ActorBackedStreamingProxyParticipantStore(dual-write surface)+ 应用层 IActorRuntime 注入

保留/重做:
- StreamingProxyGAgent per room 作 participant authority(已 own participants 字段)
- Endpoint 改 typed application/interaction service 注入,移走 IActorRuntime
- 应用层调 room current-state query 替代旧 store
- 不动 StreamingProxyNyxParticipantCoordinator(facade 边界,#885 并行)
- 不动 NyxID LLM provider / room chat semantics
- 不动 chat lifecycle path(那是 #885/#877)

测试:room actor authority + endpoint typed service + 删 singleton 后无引用残留 + projection 物化路径。
