Conversation
A streamed answer arrives as a series of cumulative snapshots and every snapshot re-rendered the whole answer, so a long reply re-parsed from the top on each chunk. Coalesce the chunks into one render per animation frame (`answer-buffer.mjs`) and always flush the newest text before the answer is finalized. Buffered frames are dropped when the card unmounts, is cleared, or starts a new question, so a stale frame cannot resurrect an old answer. The buffer falls back to a timer where the host has no animation frames (jsdom and other headless renderers), which keeps the lifecycle tests working. Syntax auto-detection is limited to a common-language subset in `highlight-options.mjs`. `detect: true` compiles every registered grammar on first use; narrowing the scan keeps auto-detection and drops that cost. Explicitly labelled blocks are unaffected. Measured on a 394-character answer delivered as 19 chunks of 20 characters: - First code block on a cold page: ~132 ms before, ~4 ms after. - A burst: 48.6 ms of CPU over 19 renders before, 11.0 ms over 6 after. - A slow stream (60 ms per chunk): 48.6 ms before, 29.6 ms after.
Replace react-markdown with @aeven-ai/hypermarkdown, which parses only the block that is still changing and caches the blocks already settled, so a long answer is no longer re-parsed from the top on every update. Answers are handed over as deltas (`stream-delta.mjs`) and finalized once the stream ends. The react/react-dom alias moves from @preact/compat 17.1.2 to 18.3.2 so packages that declare a React 18 peer range can be installed. The alias is a thin re-export of preact/compat, so the runtime implementation is unchanged. Removed as redundant: - `markdown-without-katex.jsx`, a 200-line near-duplicate of the renderer. The KaTeX-free build now swaps `math-plugin.mjs` for `math-plugin-without-katex.mjs` and `mykatex.min.css` for `mykatex-without-katex.css` through the build hook that already existed for this purpose. The minimal build ships 0 KaTeX font faces; the full build is unchanged. - `Pre.jsx`, now that the renderer has its own code-block toolbar, and the orphaned `change-children-font-size.mjs` helper. - `react-markdown`, `remark-breaks`, `rehype-raw`, `github-markdown-css`, `parse5` and the `parse5` webpack alias (nothing in `src` imported it, and the alias broke `hast-util-raw`). Rendering fixes that came with the swap: the renderer stylesheets are imported by the content-script entry so every variant ships them (they used to land in a chunk whose CSS is never packaged), list markers are drawn by the browser (`list-markers.mjs`) so bullets nested in a numbered list stay bullets and a list that resumes at another number keeps its `start`, and a thrown error is stored as its message, since the renderer takes text and would otherwise break on an `Error` object.
Reasoning models put their thinking in `delta.reasoning_content` (DeepSeek R1)
or `delta.reasoning` (OpenRouter-style) instead of `delta.content`.
`buildMessageAnswer()` read only `delta.content`, so that text was dropped
entirely and the answer appeared as if out of nowhere.
The thinking is now streamed to the card on its own channel (a `{reasoning}`
port message) and rendered as a reasoning block ahead of the answer: it opens
while it arrives, collapses with a duration once it stops, and can be reopened
afterwards.
It is deliberately not merged into the answer. `pushRecord()` still stores only
the answer text, so thinking never re-enters the conversation context on the
next turn, which is what DeepSeek does with `reasoning_content` too. Both halves
- thinking is shown, thinking is not sent back - are asserted in
`tests/unit/services/apis/reasoning-content.test.mjs`.
`<think>`-style tags that a provider streams inside the answer are split out for
the same reason (`inline-reasoning.mjs`): a leading block moves to the reasoning
channel so it stays out of the saved answer, while tags the user typed - or that
appear in prose or code - are rendered literally (`special-tags.mjs`). A block
that never closes is only treated as thinking while the stream is still running;
once it ends, the text is kept as the answer so a response truncated mid-thinking
is not lost from the conversation record.
Reasoning-only chunks no longer repost an unchanged answer, and a retry, a model
switch or an error replacement clears the previous thinking.

2. Ten locales show english thought time 📘 Rule violation ⚙ Maintainability
MarkdownRender requests the new Thought for {seconds}s translation, but that key was added only
to English and the two Chinese locale files. When users select any of the ten other supported
locales, the configured English fallback supplies the reasoning duration label.

## Issue description
The new reasoning duration label has no entry in ten supported locales and falls back to English.
## Fix Focus Areas
- src/components/MarkdownRender/markdown.jsx[77-80]
- src/_locales/en/main.json[34-35]
## Recommended Fix
Add `Thought for {seconds}s` to the German, Spanish, French, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, and Turkish locale files, using translations or clearly marked placeholders.

1. Inline thinking enters the next prompt 🐞 Bug ≡ Correctness
resolveStreamText() skips splitInlineReasoning(answer) whenever a separate reasoning field is nonempty. If a provider sends both that field and a leading <think> block in content, finish() saves the inline block as answer text, and subsequent requests include it in conversation context.
Agent Prompt
## Issue description
A separate reasoning delta bypasses splitting of a leading inline thinking block, allowing that block into saved conversation context.
## Fix Focus Areas
- src/services/apis/openai-compatible-core.mjs[135-145]
- src/services/apis/inline-reasoning.mjs[15-28]
## Recommended Fix
Split leading inline reasoning from answer content regardless of whether separate reasoning arrived. Define how the two reasoning sources combine without duplicating text, and test a stream containing both.

4. Truncated thinking stays out of the answer 🐞 Bug ≡ Correctness
finish() saves the raw answer when a leading thinking block never closes, but posts only a completion message rather than that final answer. For such a stream, the card finalizes an empty answer while showing the text solely in its reasoning block, so the visible answer differs from the saved conversation record.
Agent Prompt
## Issue description
Finalization saves an unclosed inline thinking block as answer text without updating the card's answer.
## Fix Focus Areas
- src/services/apis/openai-compatible-core.mjs[138-168]
- src/components/ConversationCard/index.jsx[262-282]
## Recommended Fix
Send a final state that lets the card display the same answer that is saved, clearing or relocating the provisional reasoning display to avoid duplication. Cover completion of an unclosed block end to end.

5. Old answer frames can cross into a new prompt 🐞 Bug ☼ Reliability
answerBufferRef retains an animation-frame callback after the effect for a changed props.question starts another request; its cleanup runs only on unmount. When an existing toolbar changes its prompt before that frame fires, the callback updates the last answer item without checking which request queued it.

Unmount cleanup does not cancel answer frames when the same card starts a request for a different prompt.

6. Raw answer markup loses supported tags 🐞 Bug ≡ Correctness
ALLOWED_TAGS supplies only p to the new renderer, replacing the previous renderer configuration that enabled raw HTML and explicitly permitted tags including br, img, table, and details. Answers containing those HTML elements, as well as the card's generated error text containing <br>, no longer retain the previously allowed markup.

7. Thinking can collapse early behind a stray answer 🐞 Bug ≡ Correctness
postStreamText posts an empty answer when splitInlineReasoning recognizes a completed <think> opener, but the card's if (msg.answer) guard discards it instead of clearing the displayed answer and partialAnswerRef. When the opener arrives across chunks, the earlier fragment remains visible beside the reasoning block, causes buildStreamedContent to close that block while the model is still thinking, and can be saved as the answer if the user stops then.
Agent Prompt
## Issue description
An opening `<think>` tag split across stream chunks can initially appear as answer text. Once the tag is recognized, the core posts an empty answer, but the card ignores it, leaving stale text displayed and buffered, closing the reasoning block early, and potentially saving the fragment if the user stops.
## Fix Focus Areas
- src/components/ConversationCard/index.jsx[262-266]
- src/services/apis/openai-compatible-core.mjs[148-158]
## Recommended Fix
In the card, distinguish an explicitly posted empty answer from a message with no answer field by handling `typeof msg.answer === 'string'` rather than checking truthiness. For an empty answer, reset `partialAnswerRef` to `''` and push the waiting placeholder (or `''`) into the answer buffer to replace the stale fragment. Alternatively, in the core, hold back answer text matching `/^\s*<[a-z]*$/i` until the possible opener can be resolved. Test an opening reasoning tag split across chunks with no subsequent answer.

8. Answers mentioning the loading class vanish 🐞 Bug ≡ Correctness
buildStreamedContent decides whether children is the card's placeholder with
children.includes('gpt-loading') instead of checking for the exact placeholder markup. A real
answer that contains that substring anywhere (for example, a question about this extension's CSS) is
replaced with '' whenever reasoning is present, so only the thinking block is shown and the answer
is hidden for good.
Agent Prompt
## Issue description
`buildStreamedContent` hides the whole answer whenever it contains the substring `gpt-loading` and reasoning is present.
## Fix Focus Areas
- src/components/MarkdownRender/reasoning-content.mjs[18-23]
## Recommended Fix
Only treat `children` as the placeholder when it matches the placeholder markup in full, for example `/^\s*<p class="gpt-loading">[\s\S]*<\/p>\s*$/`. Better still, have the card pass an explicit `isPlaceholder` flag rather than sniffing the content.

9. Thinking that mentions a closing tag spills into the answer 🐞 Bug ≡ Correctness
buildStreamedContent puts the raw reasoning text between <think>\n and \n</think> without escaping any reasoning tags inside it. If the thinking itself contains </think> (for example, a model reasoning about these tags), the renderer closes the block at that point, so the rest of the thinking appears as answer text and the block collapses early while streaming.
Agent Prompt
## Issue description
Reasoning text is wrapped in `<think>` tags without escaping, so a `</think>` inside it closes the block early.
## Fix Focus Areas
- src/components/MarkdownRender/reasoning-content.mjs[18-23]
## Recommended Fix
Before wrapping, run the reasoning through `escapeReasoningTags(reasoning)` (with preserveLeadingBlock false), so any think/thinking/reasoning tags inside it are shown as text.

This review covers the full 36-file diff at ba0b0dc. Note the branch also carries the #1103 HyperMarkdown migration (fc80bc3, a3af35a), so the diff against master is larger than this PR's own work; I validated the migration's external contract but focused the findings on the reasoning feature.

I checked every prop and plugin slot against the published@aeven-ai/hypermarkdown@0.4.4type declarations (streaming,plugins,components,controls,translations,allowedTags,lineNumbers, thewrite/resethandle, andPluginConfig.math?: MathPlugin | undefined) — all match. No dangling references to the deletedPre.jsx/markdown-without-katex.jsx/change-children-font-size.mjs.
Tests: the 40 reasoning/stream unit tests pass, the full suite is 1136 passing, and eslint/prettier are clean on the changed files.
ℹ️ Nitpicks
"Thought for {seconds}s"(and"Thinking Content") are only added toen,zh-hans, andzh-hant; the other ten locales fall back to English, so non-English users see "Thought for 12s". Adding"Thought for {seconds}s"to the remainingsrc/_locales/*/main.json(or a completeness test liketests/unit/locales/conversation-title-translations.test.mjs) would close the gap.- The reasoning tests cover the natural-finish path for an unclosed inline block, but not the abort path — which is the same code and the more common way a user interrupts a reasoning model (see inline comment).
Technical details
\n\n````markdown\n# Aborting an unclosed inline `think` block persists the chain-of-thought as the answer\n\n## Affected sites\n- `src/services/apis/openai-compatible-core.mjs:205-209` — abort branch: `resolveStreamText({ final: true })` returns `{ answer, reasoning: '' }` for `inline.unclosed`, then `pushRecord(session, question, streamText.answer)` stores the raw `think`-tagged text.\n- `src/services/apis/openai-compatible-core.mjs:144` — the `final && inline.unclosed` branch shared with `finish()`; the natural-finish behaviour is explicitly intended and tested, the abort use of it is not.\n- `src/services/apis/reasoning-content.mjs` — the card showed this text on the reasoning channel, so the stored answer no longer matches what the user saw.\n\n## Evidence\nA probe streaming a single `content` chunk of `think` + body and then aborting yields:\n`conversationRecords = [{ question: 'hi', answer: 'think…full body' }]` while the only streamed message was `{ reasoning: '…body' }`.\n\n## Required outcome\nDecide the intended behaviour when the user stops generation inside an unclosed inline reasoning block. Options: (a) keep the current truncation-safety behaviour and add a test plus a note in the PR body that Stop persists the CoT; or (b) on abort, record an empty/omitted answer (or the non-thinking remainder) so the CoT is not replayed as context.\n\n## Open questions for the human\n- Is the reasoning-field path (which stores no answer on abort) the intended contrast, or should both paths behave the same?\n\n````\n\ndeepseek-v4.1-flash (free via Pullfrog for OSS) ｜ 𝕏

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use an exact match for the placeholder, not a substring test.
children.includes('gpt-loading') treats every answer that contains the text gpt-loading as the loading placeholder. One example is an answer that discusses this CSS class. For that answer, answer becomes '' and the real answer text is not shown while reasoning exists. Compare against the placeholder markup instead, for example with a ^<p class="gpt-loading">…</p>$ test.
Proposed fix
- const answer = children.includes(ANSWER_PLACEHOLDER_CLASS) ? '' : children

Split leading inline reasoning even when a reasoning field is present.
If a stream supplies both delta.reasoning_content and answer text starting with <think>, this branch skips splitInlineReasoning. The inline block is then posted as answer text and saved by pushRecord, so it can enter the next request's conversation context. Split the answer in both cases; use the dedicated field only to select the displayed reasoning.

Send the final answer for an unclosed <think> block.
When the stream ends with an unclosed <think> block, finish saves that text as the session answer but posts answer: null. ConversationCard does not rebuild its displayed items from the updated session. The done handler preserves the existing reasoning and does not replace the answer with the saved session answer. The card can therefore display the text only as reasoning while the session stores it as the answer.
Send the final answer and clear the provisional reasoning display during finalization.

Update finalization around pushRecord and port.postMessage to send the resolved
final answer instead of answer: null, and clear the provisional reasoning
display so an unclosed think block is shown only as the final answer. Keep the
session record consistent with the answer sent to the card.

Splits part of #1084 into a focused PR, as requested there.
Depends on #1103 (HyperMarkdown migration). The branch is based on that branch, so this diff currently includes its commit as well; it shrinks to just the reasoning work once #1103 merges. Reasoning is drawn through the new renderer's native reasoning block, so this builds on that migration.
What this does
Reasoning models put their thinking in
delta.reasoning_content(DeepSeek R1) ordelta.reasoning(OpenRouter-style) instead ofdelta.content.buildMessageAnswer()read onlydelta.content, so that text was dropped entirely and the answer appeared as if out of nowhere.The thinking is now streamed to the card on its own channel (a
{reasoning}port message) and rendered as a reasoning block ahead of the answer: it opens while it arrives, collapses with a duration once it stops, and can be reopened afterwards.It is deliberately not merged into the answer.
pushRecord()still stores only the answer text, so thinking never re-enters the conversation context on the next turn, which is what DeepSeek does withreasoning_contenttoo. Both halves — thinking is shown, thinking is not sent back — are asserted intests/unit/services/apis/reasoning-content.test.mjs.<think>-style tags that a provider streams inside the answer are split out for the same reason (inline-reasoning.mjs): a leading block moves to the reasoning channel so it stays out of the saved answer, while tags the user typed — or that appear in prose or code — are rendered literally (special-tags.mjs). A block that never closes is only treated as thinking while the stream is still running; once it ends, the text is kept as the answer, so a response truncated mid-thinking is not lost from the conversation record.Smaller details:
Requested in #839; related to #848, #833.
Tests
tests/unit/services/apis/reasoning-content.test.mjs— the thinking is surfaced and not sent back in context.tests/unit/services/apis/inline-reasoning.test.mjs— leading<think>blocks, prose/code mentions, and the unclosed-block lifecycle.tests/unit/components/reasoning-content.test.mjs— how the reasoning text is wrapped for the renderer.tests/unit/components/special-tags.test.mjs— which tags are escaped versus kept literal.tests/unit/services/apis/custom-api.test.mjs— updated for "an emptydelta.contentdoes not repost the answer".Validation
npm test— 1136 passing.npm run lint— clean.npm run build— all four variants build; expected artifacts present inbuild/chromium/.Validation skipped: manual browser testing — no browser automation is available here. A smoke test would stream a DeepSeek R1 style answer and check that the thinking block streams expanded, settles on the real duration, and does not reappear after a retry.
