cluster-024: ChatStreamAsync as the only AI executor

[loning]

Summary

iter15 cluster-024 (high severity, AG-AI-STREAM-01).

• Old: ChatRuntime/ToolCallLoop/AIGAgentBase/Classifier/Studio Generate/ContextCompressor kept non-streaming ChatAsync paths invoking provider.ChatAsync directly.
• New: ChatStreamAsync is the only authoritative AI executor; offline text aggregation consumes the stream as an explicit adapter; ILLMProvider.ChatAsync remains provider-boundary only with forbidding-comment for upper layers.

Violated AGENTS.md mandate "AI 对话主链必须流式化".

Scope

12 files changed (+242/-111). Targeted ChatbotClassifier / ContextCompressor / ToolCallLoop tests pass. architecture_guards + test_stability_guards green.

See implement-cluster-024 summary and iter15 audit.

Stacked-PR

Part of iter15 batch A (with #PR-028 and #PR-029). All target the iter1-14 integration branch refactor/2026-05-19_auto-refactor-trial which has rollup PR #678 to dev.

🤖 Multi-codex review (v2, round 1) — Phase 8

Verdicts | 三组独立 codex 评审结论

Reviewer	Verdict
Architect (CLAUDE/AGENTS clause compliance)	comment
Tests (coverage + quality)	reject
Quality (readability + simplicity)	comment

Not unanimous approve → enter fix-retry loop (per Phase 8 policy, max 3 rounds before human escalation).

English

The 3 reviewer codex ran independently against origin/dev...origin/refactor/iter15-cluster-024-chatasync (three-dot diff = symmetric difference from merge-base, matching what GitHub PR shows).

• Architect (comment): no CLAUDE/AGENTS clause violation; cluster ChatStreamAsync refactor is compliant. Comments are non-blocking observations.
• Quality (comment): refactor self-doc comments present; suggests extracting the repeated StringBuilder + await foreach ChatStreamAsync aggregation into a small named helper (now appears in ≥5 production sites). Not blocking.
• Tests (reject): ScriptGenerateGAgent.GenerateAsync and WorkflowGenerateGAgent.GenerateAsync changed from ChatAsync(...) to GenerateWithReasoningAsync(...) but no matching ScriptGenerateGAgentTests.cs or WorkflowGenerateGAgentTests.cs exercises the new path. Demand: provider test double whose ChatAsync throws and whose ChatStreamAsync yields split chunks; assert concatenated stream result.

Next action (automatic): fix codex round 1 dispatched to add the missing tests on a worktree off this PR's HEAD. Round result will be posted as a follow-up comment.

3 个独立 reviewer codex 在 origin/dev...origin/refactor/iter15-cluster-024-chatasync 三点 diff (= 从 merge-base 起的对称差,与 GitHub PR 视图一致) 上跑出结论。

• Architect (comment): 没有 CLAUDE/AGENTS 条款违反,cluster ChatStreamAsync 重构符合规范。所有 comment 都是非阻塞观察。
• Quality (comment): refactor 自文档注释齐全;建议把重复的 StringBuilder + await foreach ChatStreamAsync 聚合代码 (现已在生产代码 ≥5 处出现) 抽成小的命名 helper。不阻塞合并。
• Tests (reject): ScriptGenerateGAgent.GenerateAsync 和 WorkflowGenerateGAgent.GenerateAsync 从 ChatAsync(...) 改为 GenerateWithReasoningAsync(...),但没有对应的 ScriptGenerateGAgentTests.cs 或 WorkflowGenerateGAgentTests.cs 覆盖新路径。要求:用 provider test double,其 ChatAsync 抛异常、ChatStreamAsync 按片段 yield,然后断言返回内容是拼接结果。

🤖 Fix codex round 1 — FIX_DONE:687:round-1:applied-4:rejected-0:blocked-0

Pushed: 0ceb4812

English

Fix codex addressed reviewer demands AND took quality reviewer's helper-extraction suggestion (B SCOPE_EXTEND):

• (A) Architect comment: replaced one-line note on ILLMProvider.ChatAsync with the required // Refactor (iter15/cluster-024): Old/New comment, clarifying provider ChatAsync is boundary compatibility only; formal entrypoints call ChatStreamAsync.
• (A) Quality comment: added cluster rationale to spawn-codex.sh strict-mode empty-array guard (explains why this script touch is in cluster-024's scope).
• (B SCOPE_EXTEND) Quality comment: extracted repeated StringBuilder + await foreach ChatStreamAsync aggregation into new Aevatar.AI.Core.Chat.ChatStreamContentAggregator helper. Routed classifier, ChatRuntime, ContextCompressor, ToolCallLoop, and Studio GenerateAsync through it. Reasoning-callback loops preserved as exceptional path.
• (B SCOPE_EXTEND) Tests reject: added test/Aevatar.Studio.Tests/StudioGenerateGAgentStreamingTests.cs proving ScriptGenerateGAgent + WorkflowGenerateGAgent GenerateAsync concatenate split ChatStreamAsync chunks, never call provider-boundary ChatAsync, and return empty string on empty streams.

Validation: build pass; targeted tests pass (3 Studio + 91 ChatRuntime/ToolCallLoop/ContextCompressor/Classifier); test_stability_guards.sh pass; git diff --check pass.

Diff impact: net −43 lines (28 inserted / 71 removed) — refactor consolidation reduced overall line count even with new helper + test file.

fix codex 处理掉 reviewer 需求,并采纳 quality reviewer 关于抽取 helper 的建议(B SCOPE_EXTEND):

• (A) Architect comment: 把 ILLMProvider.ChatAsync 上的一行说明替换为完整 // Refactor (iter15/cluster-024): 旧/新注释,明确 provider ChatAsync 只是边界兼容;正式入口走 ChatStreamAsync。
• (A) Quality comment: 给 spawn-codex.sh 严格模式空数组保护加 cluster 解释(说明为何这处脚本改动属于 cluster-024 的范围)。
• (B SCOPE_EXTEND) Quality comment: 把重复的 StringBuilder + await foreach ChatStreamAsync 聚合代码抽出为新的 Aevatar.AI.Core.Chat.ChatStreamContentAggregator helper,让 classifier、ChatRuntime、ContextCompressor、ToolCallLoop、Studio GenerateAsync 共用。reasoning 回调流程作为例外路径保留。
• (B SCOPE_EXTEND) Tests reject: 新增 test/Aevatar.Studio.Tests/StudioGenerateGAgentStreamingTests.cs,证明 ScriptGenerateGAgent 与 WorkflowGenerateGAgent 的 GenerateAsync 会拼接分片 ChatStreamAsync 输出、从不调用 provider 边界 ChatAsync、空流时返回空串。

验证: 构建通过; targeted 测试通过(3 个 Studio + 91 个 ChatRuntime/ToolCallLoop/ContextCompressor/Classifier); test_stability_guards.sh 通过; git diff --check 通过。

Round 1 reject was addressed

v2 tests reviewer demanded ScriptGenerateGAgentTests + WorkflowGenerateGAgentTests. Fix codex round 1 added StudioGenerateGAgentStreamingTests.cs. v3 tests reviewer confirms: "Added tests in ChatRuntimeStreamingBufferTests.cs and StudioGenerateGAgentStreamingTests.cs do assert real outcomes." — round 1 demand resolved.

Round 2 NEW demand (not anti-spiral — different evidence)

v3 tests reviewer identified a new gap exposed by the ChatStreamContentAggregator helper extraction:

• ToolCallLoop.cs:292 now sets LLMCallContext.IsStreaming = true, but no ToolCallLoopTests.cs assertion verifies middleware observes this flag. The line could regress to false and existing tests would still pass because the test provider's ChatAsync path remains functional.
• Demand: install an ILLMCallMiddleware, run ExecuteAsync, assert middleware.observed.IsStreaming.Should().BeTrue() while provider response aggregates from ChatStreamAsync. Also make test provider's ChatAsync throw to lock the boundary.

This is healthy iteration (fix round 1 extracted a helper which exposed a new middleware contract that needs its own test). Fix codex round 2 dispatched to add the missing ToolCallLoop middleware test.

Round 1 reject 已解决

v2 tests reviewer 要求 ScriptGenerateGAgentTests + WorkflowGenerateGAgentTests。fix codex round 1 加上 StudioGenerateGAgentStreamingTests.cs。v3 tests reviewer 确认: "ChatRuntimeStreamingBufferTests.cs 与 StudioGenerateGAgentStreamingTests.cs 里加的测试都断言真实结果。" — round 1 需求已解决。

Round 2 NEW demand (非死循环 — 是不同的证据)

v3 tests reviewer 识别出一个被 ChatStreamContentAggregator helper 抽取暴露出来的新缺口:

• ToolCallLoop.cs:292 现在设 LLMCallContext.IsStreaming = true,但 ToolCallLoopTests.cs 里没有断言验证 middleware 观察到这个 flag。这一行如果回退到 false,现有测试仍会通过(因为 test provider 的 ChatAsync 路径仍可用)。
• 要求: 装一个 ILLMCallMiddleware,跑 ExecuteAsync,断言 middleware.observed.IsStreaming.Should().BeTrue() 且 provider 响应来自 ChatStreamAsync 聚合。同时让 test provider 的 ChatAsync 抛异常,锁死边界。

这是健康的迭代(round 1 抽取的 helper 暴露了新的 middleware contract,需要单独测试覆盖)。fix codex round 2 已 dispatch 补这个 ToolCallLoop middleware 测试。

🤖 Fix codex round 2 — FIX_DONE:687:round-2:applied-3:rejected-0:blocked-0

Pushed: 911d38b2

English

Round 2 addressed all v3 (round-1-review) demands:

• (A) Tests v3 reject (NEW demand from round 1 helper extraction): added ToolCallLoopTests regression test with ILLMCallMiddleware asserting context.IsStreaming.Should().BeTrue() AND that response aggregates from ChatStreamAsync. Test provider's ChatAsync throws so the boundary is locked — if ToolCallLoop.cs:292 ever regresses IsStreaming = true → false, this test fails immediately.
• (A) Architect v3 comment: added // Refactor (iter15/cluster-024): Old/New marker on ChatStreamContentAggregator.AggregateResponseAsync (the new helper extracted in round 1 needed its own self-doc, which round 1 missed).
• (A) Quality v2 carried-over: actually reverted unrelated spawn-codex.sh strict-mode change out of this PR. Round 1 had added an explanation comment instead; quality reviewer's intent was a clean cluster scope, so round 2 reverts the file to origin/dev. The fix continues to live on auto-refact-dev where it belongs.

Validation: build pass; full Aevatar.AI.Tests project pass; test_stability_guards.sh pass.

Next action (automatic): re-dispatch 3 reviewer codex against new HEAD 911d38b2. Round 3 verdicts coming.

中文

Round 2 处理了所有 v3 (round-1-review) 需求:

• (A) Tests v3 reject (round 1 抽取 helper 暴露的新需求): 在 ToolCallLoopTests 加回归测试,装 ILLMCallMiddleware、断言 context.IsStreaming.Should().BeTrue()、且响应来自 ChatStreamAsync 聚合。test provider 的 ChatAsync 抛异常以锁死边界 — 如果 ToolCallLoop.cs:292 把 IsStreaming = true 回退成 false,这个测试立刻挂。
• (A) Architect v3 comment: 在 ChatStreamContentAggregator.AggregateResponseAsync 上补 // Refactor (iter15/cluster-024): 旧/新注释 (round 1 抽出的新 helper 缺自文档,round 1 没补)。
• (A) Quality v2 遗留项: 真正把无关的 spawn-codex.sh 严格模式改动回退出本 PR。round 1 是加了解释注释,但 quality reviewer 的本意是 cluster scope 干净,所以 round 2 把文件回退到 origin/dev。修复本身继续在 auto-refact-dev 上,属其所归。

English

Round 3 demands (small, concrete, in-scope)

1. Architect — Refactor comments accuracy:
   • AIGAgentBase.cs: protected ChatAsync helper overloads were deleted but no nearby // Refactor (iter15/cluster-024): comment documents the deleted surface. Add one.
   • ScriptGenerateGAgent.cs:57 and WorkflowGenerateGAgent.cs:57: existing Refactor comment says "old pattern was non-streaming ChatAsync directly called provider.ChatAsync" — but GenerateWithReasoningAsync was already streaming on origin/dev. Either remove the comment or rewrite it to describe the real refactor (cluster-024 made it route via shared aggregator, not via direct ChatAsync).
2. Tests — source-regression scan widening:
   • ChatRuntimeStreamingBufferTests.cs:390 source-regression assertion only scans src/Aevatar.AI.Core, but the cluster also removed formal-entrypoint ChatAsync use from src/Aevatar.Studio.Hosting and agents/Aevatar.GAgents.ChatbotClassifier. A future regression in those paths wouldn't be caught.
   • Extend scan to all three paths; keep provider boundary abstraction excluded.

Quality already approves (specifically calls out the ChatStreamContentAggregator extraction landed cleanly + size/naming all good).

Fix codex round 3 dispatched to address both. If round 3 succeeds → unanimous approve → auto-merge. If round 3 fails to flip the comments to approve → controller will escalate via needs-human-review label per Phase 8 anti-spiral safeguards.

中文

Round 3 需求(都小、具体、in-scope)

1. Architect — Refactor 注释准确性:
   • AIGAgentBase.cs: protected ChatAsync 重载被删,但附近没有 // Refactor (iter15/cluster-024): 注释记录已删的 surface。补一个。
   • ScriptGenerateGAgent.cs:57 / WorkflowGenerateGAgent.cs:57: 现有 Refactor 注释说"老模式是非流式 ChatAsync 直接调 provider.ChatAsync" — 但 GenerateWithReasoningAsync 在 origin/dev 上本来就是流式的。要么删该注释,要么改写为描述真实重构 (cluster-024 让它走共享 aggregator,而不是直接走 ChatAsync)。
2. Tests — source-regression 扫描范围扩大:
   • ChatRuntimeStreamingBufferTests.cs:390 的 source-regression 断言只扫 src/Aevatar.AI.Core,但本 cluster 也从 src/Aevatar.Studio.Hosting 和 agents/Aevatar.GAgents.ChatbotClassifier 移除了正式入口对 ChatAsync 的调用。这些路径未来若回退,扫描捕不到。
   • 扫描扩展到这三处;保持 provider 边界抽象豁免。

Quality 已 approve(明确提到 ChatStreamContentAggregator 抽取干净,大小/命名都好)。

fix codex round 3 已派出处理上述两项。round 3 成功 → unanimous approve → auto-merge。失败 → controller 按 Phase 8 anti-spiral 升级 needs-human-review label。

Round 3 addressed all v4 (round-2-review) actionable comments. Diff is tiny: 4 files, +12 / -9.

• Architect comment Refactor/project namespace #1: added missing // Refactor (iter15/cluster-024): anchor on AIGAgentBase.cs:202 documenting that the removed protected ChatAsync helpers used to allow GAgents to use the non-streaming executor as a formal conversation path; subclasses now use ChatStreamAsync with explicit local aggregation only when needed.
• Architect comment Feature/cqrs projection suite #2 (×2): removed inaccurate Old/New comments from ScriptGenerateGAgent.GenerateWithReasoningAsync and WorkflowGenerateGAgent.GenerateWithReasoningAsync — those methods were already streaming on origin/dev. Only the GenerateAsync methods (which previously called direct ChatAsync) keep the refactor comment.
• Tests comment: widened the source-regression assertion in ChatRuntimeStreamingBufferTests.cs:390 from scanning only src/Aevatar.AI.Core to scanning all three user-facing AI executor surfaces touched by this cluster: src/Aevatar.AI.Core + src/Aevatar.Studio.Hosting + agents/Aevatar.GAgents.ChatbotClassifier.

Round-by-round summary

• Fix round 1 (4 fixes): addressed quality reviewer's ChatStreamContentAggregator extraction suggestion (5 production sites now share one helper); added StudioGenerateGAgentStreamingTests for the tests-reviewer reject demand
• Fix round 2 (3 fixes): addressed v3 tests reject (new demand surfaced by round-1 helper extraction): added ToolCallLoop middleware test asserting IsStreaming == true + reverted unrelated spawn-codex.sh drive-by
• Fix round 3 (4 fixes): addressed v4 comments: added missing Refactor anchor on AIGAgentBase.cs deleted ChatAsync helpers; removed inaccurate Refactor comments on GenerateWithReasoningAsync (was already streaming on dev); widened source-regression scan from src/Aevatar.AI.Core only to all three touched paths (+Studio.Hosting + Classifier)

Final cluster shape

• ChatStreamAsync is the only authoritative AI executor at all formal entrypoints
• Direct provider.ChatAsync calls only allowed at provider boundary abstraction (excluded from regression guard)
• Shared ChatStreamContentAggregator helper for offline aggregation use cases
• Source-regression assertion locks the no-regression rule across src/Aevatar.AI.Core + src/Aevatar.Studio.Hosting + agents/Aevatar.GAgents.ChatbotClassifier

Next action

PR is currently BEHIND origin/dev by 6 commits + CI still pending on HEAD 7acfda4b. Controller will:

1. Merge origin/dev into the cluster branch (clean — same path as 688/689 took)
2. Run local guards
3. Push (re-trigger CI)
4. Wait for CI green → gh pr merge --merge to dev

Cluster-024 will then move to clusters_done.

各轮要点

• Fix round 1 (4 项): 处理 quality reviewer 关于抽取 ChatStreamContentAggregator 的建议(生产代码 5 处共享一个 helper);为 tests reviewer 的 reject 补 StudioGenerateGAgentStreamingTests
• Fix round 2 (3 项): 处理 v3 tests reject (round 1 抽取 helper 暴露的新需求):加 ToolCallLoop middleware 测试断言 IsStreaming == true + 回退无关的 spawn-codex.sh drive-by
• Fix round 3 (4 项): 处理 v4 各项 comment: 在 AIGAgentBase.cs 被删的 ChatAsync helper 处补缺失的 Refactor 锚点; 删除 GenerateWithReasoningAsync 上不准确的 Refactor 注释 (那俩在 dev 上本来就流式); 把 source-regression 扫描从只看 src/Aevatar.AI.Core 扩展到三个 touched 路径 (+Studio.Hosting + Classifier)

最终 cluster 形态

• ChatStreamAsync 是所有正式入口唯一权威 AI executor
• 直接调 provider.ChatAsync 只在 provider boundary 抽象层允许 (regression guard 豁免)
• 共享 ChatStreamContentAggregator helper 服务离线聚合场景
• source-regression 断言把"不回退"规则锁在 src/Aevatar.AI.Core + src/Aevatar.Studio.Hosting + agents/Aevatar.GAgents.ChatbotClassifier 三处

下一步

PR 当前落后 origin/dev 6 commits + HEAD 7acfda4b CI 还在跑。controller 将:

1. 把 origin/dev merge 进 cluster 分支 (clean,和 688/689 走过的路径一致)
2. 跑本地 guards
3. push (重启 CI)
4. CI 全过 → gh pr merge --merge 进 dev

cluster-024 随后进入 clusters_done。
