…lapsible timeline Repository Q&A upgrade modeled on mature chatbot UX (ChatGPT-style): - Fix sticky header vanishing when Radix popups open: neutralize react-remove-scroll's overflow:hidden with overflow:clip so the viewport stays the sticky containing block; drop Header to z-40. - Real streaming for the final answer: new AIService.requestTextStream with SSE parsing for openai/openai-responses/openai-compatible/ deepseek/mimo/claude/gemini; incremental message rendering (60ms throttle), stick-to-bottom scrolling, partial answer kept on stop, silent downgrade to blocking on any stream failure. Reword the settings copy that misleadingly referenced "browser mode". - Task depth selector in the chat composer (default/quick/deep/ unlimited, min 2 evidence rounds); 'default' follows the advanced settings budget, presets bypass clamps with fixed safety ceilings and couple to answer length directives. Persisted via settings. - Collapsible "This turn's work" timeline: collapsed by default with a live current-step line and total duration; expanded view keeps the grouped details. Hover action bar with copy (citations stripped) and regenerate (re-runs the last turn at the current depth). - Citation badges: inline file:line references resolve against the turn's evidence and render as hover cards showing the excerpt, with a click-through to the pinned-SHA GitHub blob line anchor. - Answer quality: replace the structured-JSON answer pipeline with a unified free-form markdown prompt (conclusion first, ## sections, fenced code blocks, GFM tables, mermaid only when needed) plus the existing source-verification/repair/digest fallback chain. - Retrieval quality & harness: tolerant heading matching, up to 6 sections per target, 24k excerpt cap, 96k evidence block cap, wider code windows (±24/60, 4 windows), up to 3 parallel reads per round with in-flight dedupe, 20s tool-level timeouts, answer step timeout independent of the research budget, fake tool event names removed. Tests: SSE parser suite, streaming turn (increment + fallback), task-depth presets, citation utils; schema normalization extended. Fix a pre-existing sessionRepository test broken by jsdom 24's localStorage prototype change.

The CI typecheck (tsc -b --noEmit) flags 'streamed' as an excess property in the requestTextStream debug logs; declare it on the logAIRequestDebug httpDetails type instead. Local bare 'tsc --noEmit' silently no-ops because the root tsconfig only has project references.
…allback test Spy-based interception is jsdom-version/platform dependent: the Storage.prototype spy passed in CI but not locally, and the instance spy passed locally but not in CI. Swapping the window.localStorage property for a throwing stub exercises the same fallback path deterministically on every platform.

821-832: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win建议放宽整段 JSON 降级的判定条件。
当前条件要求
content-type明确包含application/json才走整段 JSON 降级。部分 OpenAI 兼容端点在忽略stream: true时返回text/plain或不返回content-type。这种响应会进入 SSE 解析分支，extractDelta对每一行返回空串，最终抛出No content received from AI service (stream)。同时!response.body为真时当前代码调用response.json()，该调用会因空 body 失败，错误信息与真实原因不符。建议改为：只有
content-type明确包含text/event-stream时才按 SSE 解析，其余情况按整段 JSON 处理；并对!response.body单独抛出明确错误。♻️ 建议的调整
const contentType = response.headers.get('content-type') || ''; - if (!response.body || (!contentType.includes('text/event-stream') && contentType.includes('application/json'))) { + if (!response.body) { + this.logAIRequestDebug(startTime, { apiType, model, configId }, { error: 'empty response body' }, { url: maskedUrl }); + throw new Error('No content received from AI service (empty body)'); + } + if (!contentType.includes('text/event-stream')) { // 服务端忽略 stream:true 直接返回整段 JSON：一次性回调后返回。 const data: unknown = await response.json();🤖 Prompt for AI Agents

- useRepositoryChat: cancel the pending throttled stream flush as soon as the turn result arrives; a late timer could overwrite the completed message back to streaming status with no evidence ids (Major). - RepositoryChatSheet: drop aria-live=polite from the scrolling message region (screen readers re-announced the whole thread every ~60ms while streaming) and add an sr-only role=status region that announces the terminal answer state once. - citationUtils: reject URL-scheme and host:port tokens in parseCitationToken so stripCitationsForCopy no longer removes inline code spans like `http://localhost:3000`. - MarkdownRenderer: fall back to the default inline code rendering only when renderInlineCode returns null/undefined, preserving valid nodes such as 0/''/false. - aiService: treat only text/event-stream responses as SSE and parse everything else (text/plain, missing content-type) as a full JSON response; throw a clear error on an empty response body instead of a confusing response.json() failure. - aiService: skip streaming for deepseek-reasoner (see PR comment for rationale - reasoning_content must stay on the blocking path). - repositoryChatService: the answer repair call now reuses the full answerMaxTokens budget; the previous 3k cap could truncate the repair output and fail source validation again. - repositoryChatService: the answer repair call now reuses the full

…ck code retrieval User-reported: a streamed answer was correct, then the final turn was replaced with the "could not bind sources" digest, and the visible text leaked [^E1]-style footnote markers. Root causes and fixes: - Exact-string citation matching rejected sub-range citations (model cites lines 170-180 inside an evidence window 166-222). References that fall inside an evidence window are now canonicalized to the window's exact reference in normalization, accepted by the per-section check, and accepted by the evidence gate assessments. - Models sometimes ignore the citation format and emit [^E1] footnotes with definitions. mapFootnoteReferences rewrites markers whose definitions resolve to evidence into canonical backticked citations and drops the definition lines. - The validator discarded the whole answer when any section lacked a citation. validAnswer now runs a ladder: strict per-section check → footnote-mapped check → salvaged answer (unverifiable markers stripped, at least one valid reference required). Only answers with no valid reference at all still fall through to repair → digest. - System/user prompts now state the citation format as a hard requirement, demand at least one citation per paragraph/section/table, and explicitly forbid footnote markers. - CodeRabbit round 4: callModelWithRetry accepts a deadline and recomputes the remaining answer window per attempt (with backoff) instead of reusing the initial remaining time. - Code retrieval no longer depends on the gate choosing read_code: the planner proposing a code target unlocks code reads, and stalled documentation retrieval (no-progress round with budget headroom) auto-escalates to code. Understanding/plan/gate prompts now allow and encourage code targets when docs cannot answer questions about defaults, flags, or concrete behavior.
…d citation hover - MarkdownRenderer wraps markdown tables in a horizontal-scroll container; the chat scope switches tables to full-width with wrapping cells (the previous display:block + width:max-content pushed the only scrollbar below tall tables, so wide tables looked cut off). - Long tokens (inline code, URLs, table cells) can break in the narrow chat sheet instead of overflowing. - CitationBadge hover excerpt is syntax-highlighted via highlight.js, picking the language from the evidence file extension with highlightAuto fallback, on a transparent background that follows the app theme. - Copy / regenerate hover actions are right-aligned under the answer.

CodeRabbit round 5:
- validAnswer no longer returns a salvaged answer merely because it
contains one valid reference. Strict per-section validation (with
footnote mapping) stays first; on failure, pruneUnverifiableSections
keeps only cited sections and demotes uncited paragraphs into an
explicit "Unverified or missing information" block — every shown
claim is either cited or clearly marked unverified, and a mostly
correct answer is no longer discarded wholesale.
- The citation-repair call now shares the answer deadline: skipped in
favor of the digest when the window is exhausted, and bounded by the
remaining window otherwise.
- .markdown-table-scroll table drops the upstream max-width cap so the
wrapper is the sole horizontal scroll container.
User-reported rendering fallout (screenshots): most citations failed to
render as badges because models emit variants the strict parser reject:
- leading "/ /path" (slash + space) and "//path" prefixes
- em/en dash separators ("— 1-69") alongside "-"
- trailing supplementary ranges ("/src/a.ts — 1-69、397-481")
- doubled closing backticks after a citation ("…- 49-76``")
parseCitationToken / parseSourceReference now normalize the prefix,
accept — and – separators, ignore supplementary ranges (the badge links
the first), and stripUnverifiableMarkers collapses stray closing
backtick runs after citation-like ranges. Chat markdown pre blocks
scroll horizontally within bounds so ASCII drawings and long code lines
stop clipping at the sheet edge.

Round 5 审计修复 + 截图问题修复（75d5cb0）Round 5（CodeRabbit，3 条）

守卫不回退： 验证： |
…t retrieval
User-reported regression: the streamed answer was correct, but the
finalized content was replaced by the "could not bind sources" digest,
and citations showed as bare plain text ("/README.md - 35-44").
Root cause: the bare-citation rewrite regex required at least one
directory segment ("dir/name.ext"), so root-level files like
"/README.md - 35-44" were never canonicalized, failed per-section
validation, and pushed the whole answer to repair → digest. The regex
now accepts any number of leading slashes and zero directory segments,
plus em/en dash separators.
Retrieval priority (user directive: README always first, code only when
documentation is insufficient and the intent needs it):
- round-1 plans may not unlock code reads anymore; a plan-proposed code
target only unlocks from round 2 on AND after documentation retrieval
has stalled (no-progress counter > 0), keeping the stall-based
automatic escalation intact.
- when every planned target was a (not yet eligible) code target, the
planner now falls back to the first unread documentation candidate
instead of ending the turn.
- plan prompt states the round-1 documentation-only rule explicitly.
Also: doubled/tripled closing backticks after a citation range are now
collapsed by parity of preceding unpaired backticks (keep one closer
when an opener exists, drop the run otherwise), so model typos like
"…- 49-76```" no longer leak literal backticks into the answer.

Backend-proxy mode is untouched. - repositoryChatService: README/docs-first is now unconditional — even when query understanding classifies the intent as code, the round-1 outline reads documentation and codeEligible starts false. Code reads unlock from round 2 via the planner proposal (allowed immediately for code-intent questions) or the stall-based escalation, both gated by the code budget. Regression test asserts README is read before any code file for a code-intent question. - pruneUnverifiableSections: standalone headings are now attached to the section that follows them — when that section is demoted to the unverified block its heading goes with it, so no orphan headings are left behind.

…ss SSE - normalizeEvidenceReferences / mapFootnoteReferences: a covered sub-range citation now canonicalizes to the covering evidence's normalized path while keeping the line range the answer actually cited, instead of being widened to the full evidence window — the badge jumps to the cited lines. - aiService: responses without a Content-Type header are sniffed — bodies containing data: frames are parsed through the SSE delta extractors (incremental onChunk), everything else falls back to the JSON / plain-text single-shot path. The empty-body guard moved to the SSE branch it protects (the sniff and text fallbacks use text()). Regression tests: headerless SSE parses incrementally; headerless plain text falls back.

The explicit text/event-stream path only split lines on LF. Bodies whose events are separated by bare CR merged into one buffer and the EOF flush handed a multi-JSON payload to the delta extractor, ending in a "No content received (stream)" error. Line splitting now follows the SSE terminator rules (CRLF / LF / CR) with a deferred decision for a \r at a chunk boundary that may pair with the next chunk's \n, and the EOF residual is split by the same rules (covering an unterminated final line, bare-CR separators, and a dangling trailing \r). Regression test covers a whole-body bare-CR stream.

… block redirects - Headerless Content-Type sniffing now only takes the SSE result path when at least one data frame yields a valid non-empty delta for the current apiType. Plain prose that merely contains data:-prefixed lines (docs about SSE, logs) falls through to the JSON / raw-text fallback instead of throwing a no-content error. - All four direct fetch call sites (openai, openai-responses, claude, gemini in requestText plus requestTextStream) now pass redirect: 'error' — credentials travel in headers or, for Gemini, in the URL, and must never follow a redirect to another origin. - Tests: redirect init is captured and asserted; headerless prose with data:-prefixed lines falls back to the full raw text.

概述
对 AI 仓库问答做一次贴近成熟 chatbot（ChatGPT 类）交互的体验升级，覆盖 6 项需求 + agent loop 质量优先优化。Closes #311（若尚未建 issue 可忽略此行）。
变更内容
修复
overflow: hidden，sticky Header 的参照物从视口变成文档顶部被"吸"出屏幕。改用overflow: clip（阻止滚动但不创建滚动容器），一条 CSS 修复该页所有弹层；Header 降为z-40。streamingMode此前是死设置、文案"浏览器模式自动降级"为写死文本。现在：AIService.requestTextStream对 openai / openai-responses / openai-compatible / deepseek / mimo / claude / gemini 实现 SSE 增量解析；新功能
完成/总数+ 运行中实时当前步骤 + 总耗时；展开后保留原分组时间线。assistant 消息底部悬浮操作栏（ChatGPT 式）：复制（剔除/path - 行号引用标注，不碰代码块）+ 重新生成（重跑最后一轮、按当前深度）；触屏常显、键盘聚焦可见。##小节、带语言标注围栏代码块、GFM 表格、确需才用 mermaid、引用紧跟句子），篇幅随深度耦合；引用核验/修复/digest 兜底链保留。Agent loop / harness（质量优先）
测试
Storage.prototype打桩在 jsdom 24 失效，改为对实例打桩；eslint、tsc --noEmit、vite build（含 bundle 检查）全部通过；npm run test:run64 文件 / 565 用例全绿。风险与说明
