From 502730bbba6e607726f75544e4bcb8143e221e3c Mon Sep 17 00:00:00 2001 From: alkinun Date: Mon, 27 Jul 2026 09:36:02 +0300 Subject: [PATCH] Studio: add Deep Research (#7219) * Studio: add durable Deep Research workflows * Studio: preserve research integration after upstream updates * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: keep research worker compatible with Python 3.11 * Studio: address Deep Research lifecycle review * Studio: preserve durable research recovery * Studio: preserve research stream and context * Studio: harden research sources and limits * Studio: align research with shared chats * Studio: guard durable research actions * Studio: protect durable research turns * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: deepen durable research decisions * Studio: protect research prompts and queries * Studio: slim research stream deltas * Studio: preserve research evidence and citations * Studio: harden Deep Research (CI, prompt injection, query PII, config, citations) - Fix backend CI: add research_runs_router to the synthetic routes stub in test_desktop_auth so studio.backend.main imports under the health-check test. - Escape prompt-delimiter tags in the decision and synthesis prompts so gathered web/document content cannot close an wrapper and inject instructions into the local planner/decision/synthesis model. - Extend the public-query sanitizer to redact Luhn-valid payment cards, phone numbers, non-global IPs, and labeled private identifiers before a query can reach web search. - Reject nested credential keys in inferenceRequest and ragScope, not just top-level keys, when persisting a durable run config. - Treat maxSources as one budget shared across web and document sources (collection and resume paths) instead of per type, which allowed up to 2x the configured cap. - Preserve document citations whose filename contains a closing bracket by tokenizing valid citations before stripping invalid ones. - Persist Deep Research off when switching to an external model and when enabling Web Fetch so a refresh cannot rehydrate a mutually-exclusive state. - Add regression tests for the query, prompt, citation, and config hardening. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: make the research claims table migration atomic The owner-scoped to global claims migration ran its RENAME, CREATE, INSERT and DROP in autocommit, so an interruption after CREATE left the new table empty, orphaned the rows in the legacy table, and never re-triggered. Wrap the rebuild in an explicit transaction so a crash rolls back cleanly and the migration re-runs on the next boot. * Studio: block message edits and regeneration during an active research run After a reload a durable research run is followed by the research store rather than an assistant-ui run, so thread.isRunning is false while research is still active. Message edit, refresh and the edit composer previously gated only on isRunning, which let a normal generation start alongside the running research run. Gate them on the active thread's research state as well. * Studio: keep the plan review mounted through approval Keying PlanReview on planRevision remounted it mid-approve when updateResearchPlan bumped the revision, resetting the local pending flag and re-enabling Start research while the approve was still in flight, which allowed a duplicate approve. Key on runId only. * Studio: drop the redundant deep-research persistence change setCheckpoint already persists Deep Research off for external models at the top of the function, so the added saveBool was a duplicate, and clearing Deep Research from setWebFetchToolsEnabled guarded a state that is not reachable (Deep Research is local-model only while the Web Fetch pill is external-provider only). Revert both to the pre-hardening version. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: harden Deep Research citations, query privacy, and message protection Address review findings in the Deep Research backend: - Escape an unbalanced ")" in citation destinations so a source URL cannot close the markdown link early and inject a second link, keeping balanced parentheses literal. - Match raw-URL citations on whole tokens so a URL sharing another URL's prefix is no longer partially rewritten. - Redact non-global IPv6 addresses in public search queries, matching the existing IPv4 handling. - Detect credential key names after normalizing case and separators so nested openaiApiKey, accessToken, and clientSecret values cannot be persisted. - Reject client edits to server-managed research prompts and reports at the storage layer; only the internal writers pass allow_research_update. - Scope research searches to the first allowed domains instead of dropping site scoping for large allow lists. - Persist the same fetch evidence bound used during live synthesis so a resumed run is not shortened. - Scope run completion so it only replaces this run's message parts. Add regression tests for the above. * Studio: fix Deep Research SSE framing, source counts, and favicon privacy - Normalize the whole SSE buffer so a CRLF split across transport chunks still frames events. - Count web and document sources together in the activity header so a RAG-only run is not shown as zero sources. - Cap the plan editor at the run's configured maxSteps instead of a hard-coded 30. - Add an allowRemoteIcons opt-out to the sources components and disable third-party favicon requests for research sources so visited domains are not leaked. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: address final Deep Research review findings * Studio: fit Deep Research synthesis evidence to loaded context, add opt-in web grounding Size the synthesis evidence budget to the loaded model context so the prompt is not silently truncated on small contexts. When the evidence overflowed the window the report degenerated (it echoed the evidence tail instead of writing); the budget now reserves tokens for the prompt scaffolding and converts the remainder to chars, keeping the full cap when the context is unknown. Add opt-in web grounding for auto-read: read the top search results, ingest them into an ephemeral RAG scope, hybrid-retrieve the passages most relevant to the question with the existing knowledge-base retriever, and fold those chunks into the step evidence. The scope is per call and deleted afterwards, so a user's knowledge base is never touched. Off by default; enable with UNSLOTH_RESEARCH_AUTO_SCRAPE=1. Gated per run by budgets["maxAutoScrape"], so runs created without it keep legacy snippet-only behavior, and grounding is skipped when the loaded context is too small for the prompt. Add tests for the adaptive evidence budget, scraped-text cleaning, the ephemeral web-RAG retrieval and scope cleanup, and the auto-read evidence path. * Studio: read Deep Research synthesis context from the inference orchestrator Make the adaptive synthesis-evidence budget actually engage in the normal Studio architecture. _loaded_context_length read core.inference.inference, the low-level backend that lives in the model subprocess and stays unpopulated in the main web process where the research supervisor runs, so it returned None and the budget silently fell back to the 32000 character cap (leaving the report exposed to the truncation this was meant to fix). Read the inference orchestrator instead, and the llama.cpp backend for GGUF, mirroring routes.inference._monitor_context_length so the budget sizes to the context the API layer serves. Verified on a running server: at a 12288 token load the probe now reports 12288 and the budget adapts to 24576 characters instead of the 32000 fallback. Also: - Reserve context for the generated report as well as the prompt scaffolding (raise the reserve to 4096 tokens) so evidence does not crowd out the output on a small window. - Honor a numeric UNSLOTH_RESEARCH_AUTO_SCRAPE by passing the per-run maxAutoScrape as the page cap to the scraper, instead of always reading the maximum. - Guard the web-RAG connection acquisition so a get_connection failure returns the documented empty result rather than propagating. - Add a synthesis-context test that patches the real backend accessor (not the probe itself) so the production wiring is exercised, plus a scrape page-cap test. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: harden Deep Research query redaction and research autosave - research_runs: extend the opaque-token allowlist so unlabeled Hugging Face (hf_) and GitLab (glpat-) tokens are redacted before a query can reach web search, without over-redacting public model or version ids. - runtime-provider: for a server-managed research message, echo the backend-stored metadata verbatim on autosave. Merging the client metadata re-added client-only fields the server never persisted, so the server-side guard saw a diff and rejected every streamed or snapshot update with 409. * Studio: keep composer tool pills always accessible after merge The merge left the composer line marked always-expanded (data-expanded "true") while the inner pill row was still gated behind composerExpanded, so the Search and Code toggles disappeared once the permission mode was "off" with no other toggle set. Render the primary tool pills unconditionally, matching the always-expanded layout, and drop the now unused composerExpanded and permissionMode locals. Fixes the Chat UI Playwright check that asserts the Search and Code pills stay visible. * Studio: update Deep Research composer contract to always-expanded layout The always-expanded composer no longer routes effectiveDeepResearchEnabled through a composerExpanded expression, so the frontend contract now checks that it gates the Deep Research composer button render instead. * Studio: do not bind a research run to a populated assistant reply create_run adopted any assistant message under the user turn whose researchRunId was unset, including a prior answer reused by a retry. On completion _update_assistant drops the untagged text and source parts, so that answer was silently overwritten. Only bind to an empty placeholder or this run's own message, and reject a reply that already carries content. * Studio: harden Deep Research synthesis budget, prompt shielding, and message protection - research_runs: split the synthesis evidence budget evenly across notes so a small context still keeps a slice of every research step instead of dropping the later steps after the earliest ones fill the budget. - research_runs: shield the research question and approved plan before placing them in the decision and synthesis prompts, so a closing delimiter in either cannot escape its block and inject sibling sections. - research_runs: redact bearer authorization tokens from public search queries. - studio_db: include attachments in the research-message change check and guard direct attachment deletion, so server-managed research prompts and responses cannot be mutated through the attachment paths. - chat_history: map the protected-message conflict on attachment deletion to 409. * Studio: strip invalid document citations that contain brackets The invalid-citation regex stopped at the first closing bracket, so a citation whose filename contained brackets left its tail (".pdf, p. 9]") in the report. Match a balanced bracketed span so the whole invalid citation is removed; valid citations stay protected by the earlier tokenization pass. * Studio: free the RAG search slot when a lookup times out or is cancelled The bounded knowledge-base search held the sole admission slot in a detached worker until the search returned, so a lookup that outlived its timeout (a stalled embedding or blocked vector call) kept the slot forever and starved every later lookup, disabling knowledge-base retrieval globally. Release the slot from the caller when it stops waiting, exactly once, so a detached worker finishes without re-holding it. * Studio: remove Websites label from research composer * Studio: fix Deep Research review findings (RAG slot bound, orphaned workers, hardening) - Bound the shared RAG search slot to one running worker. The search that is doing the embedding/index/GPU work now owns the admission slot until it finishes, instead of freeing it on caller timeout while the detached worker keeps running, which let a second search enter and stack concurrent work behind the capacity-of-one semaphore. - Cancel active research runs before deleting their thread, project, or all history. Deleting cascade-drops the run row, but the worker only notices at its next lease check, so it could keep doing model/web/RAG work for a run that no longer exists; signalling cancel first shortens that window. - Shield the planner prompt's conversation and question with _shield_untrusted, matching the decision and synthesis prompts, so untrusted text cannot forge planner delimiters. - Do not let a research key-revocation failure replace a successful non-streaming completion; log it like the streaming path does. - Include created_at in the protected research-message guard so a client cannot reorder server-managed prompt/response messages while leaving the body intact. - Reject non-scalar ragScope values; a nested container evades the sensitive-key scan when its inner keys are unlisted and would reach retrieval code that expects a scalar scope id. Adds regression tests for each. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: remove research composer globe icon * Studio: use Hugeicons telescope in research composer * Studio: use Telescope02 icon in research composer * Studio: standardize Deep Research telescope icons * Studio: move Deep Research below web and code tools * Studio: merge grounded page excerpts with search snippets instead of replacing When auto-scrape grounding retrieved page-body chunks, it replaced the raw search-result text for that step. If the retrieved chunk was a distractor or dropped the key fact, the answer-bearing search snippet was lost and grounded runs regressed below snippet-only accuracy on factual questions (e.g. returning Apache 2.0 instead of the Qwen License, 403 instead of 404, or a single mirror diameter instead of the sum). Keep the search snippets and append the grounded excerpts as supplementary evidence via a small _merge_scraped_evidence helper. Grounding stays opt-in and off by default, so legacy runs are unchanged. Adds regression tests. * Studio: fix stale website access assertion in Deep Research contract test The dialog heading was renamed to a DialogTitle, so the contract test still asserted a Websites that no longer exists and failed on every branch built on this one. Assert the current heading instead. * Add AGPL-3.0 SPDX header to the two new test files for PR #7219 * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Fix citation loss, effort clamping and nested inferenceRequest for PR #7219 Three review findings, each with a regression test that fails without the fix. Citation dropped for a bare URL in prose parentheses. _RAW_URL swallows the closing paren and the old trim set only stripped ".,;:!?", so the catalog lookup missed and the validator deleted the whole citation, leaving an unbalanced "(" in the report. New _trim_url_tail follows GFM extended autolink path validation: one right-to-left pass that interleaves punctuation and unmatched-")" trimming. Both rules must run in the same loop, else "https://x/y.)" keeps a stray dot. Balanced parens inside a URL (Wikipedia-style) still survive. Output verified against cmark-gfm on nine cases, including "https://x/foo)bar)" which must keep ")bar". Research runs forwarded reasoningEffort unclamped. The local chat path clamps to the loaded model's advertised levels; the research branch did not, and the backend only validates enum membership, so llama.cpp dropped a level the model lacks and the whole durable run silently fell back to the template default. Now uses the same helper and the same levels as normal chat. Note this makes "max" on a gpt-oss low|medium|high model resolve to "low" rather than falling through to the template default, matching normal chat exactly; the divergence between the two paths was the bug. Nested inferenceRequest values were persisted. Every allowed field is a scalar and the numeric/bool/enum ones reject a container while coercing, but "model" is stringified with str(), which never raises, so {"auth": "sk-..."} slipped past the sensitive-key scan ("auth" is not on the list) into the durable run config as the model id. Mirrors the ragScope guard already in this PR. Verified: 542 passed across the research/web/sandbox/chat-history backend suites, frontend contract 10 passed, tsc --noEmit clean. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Fix report-stalling regex, uncataloged KB evidence and bracketed titles for PR #7219 Catastrophic backtracking in _DOCUMENT_CITATION. The alternation (?:[^\[\]]+|\[[^\[\]]*\])* backtracks exponentially on an unterminated "[Document:" with no later bare "]", which is ordinary malformed model output and exactly what this sanitizer exists to handle. Runtime quadrupled every two characters; one realistic 76-char line did not finish in 90s. It runs synchronously inside async _research (the line below it uses asyncio.to_thread), so a single bad report pins the event loop and stalls all of Studio, not just the run. Replaced with the language-equivalent unrolled form, verified identical on well-formed inputs including bracketed filenames, and linear: a 20,000-char tail now takes 0.4ms. Not using possessive quantifiers or atomic groups, which need Python 3.11 while this package declares >=3.9. Uncataloged knowledge base evidence reached synthesis. When maxSources is already full, every returned chunk hits the continue, so accepted_rag_sources stays empty, the "if accepted_rag_sources" rebuild no-ops and rag_result keeps the raw KB text. That text has no document_source_catalog entry, so the validator strips any citation to it and synthesis is left building claims on private KB chunks it cannot attribute. Cleared, gated on rag_sources so a text-only KB reply is still passed through. The resume branch built rag_evidence from all restored sources with the same hole, so it now mirrors the live loop. Bracketed source titles destroyed their own citation. The catalog gave the model the raw title while the citation writer stripped brackets. Search titles routinely carry one ("[PDF] Annual Report"), and the prompt tells the model to copy the title verbatim, producing a label the validator cannot match. Both sides now share _citation_title. Verified: 756 passed across the research/web/sandbox/chat-history/rag backend suites. Each fix has a regression test that fails without it. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Keep a durable run alive when no model is loaded for PR #7219 A durable run is claimable within the supervisor's poll interval of startup (main.py starts it in the lifespan, and claim_next takes any 'running' run whose lease expired), Studio has no startup model auto-load, and the browser is not connected yet. So restarting Studio mid-run reliably lands the next model call on the local endpoint's HTTP 400 "No model loaded". That 400 is not retryable: _completion retries only >= 500, and _stream_completion, which serves both planning and synthesis, has no retry at all. The run is marked failed, and the only recovery is retry, which sets report_text NULL and deletes every research_plan_step, research_source and research_document_source. Up to an hour of scraping and synthesis is lost on a plain restart, on the feature whose whole point is surviving one. Treat only that refusal as transient: wait up to the run's own modelTimeoutSeconds for a model to come back, then re-send. Any other 400 still fails immediately, so no behaviour changes on the happy path. The wait polls _check_active, so cancellation and lease loss are still honoured, and the model probe fails open, so a probe error can only send a request, never withhold one. Each wait is bounded by the run timeout and the number of waits per call is capped, so a model that keeps disappearing cannot re-send forever. Deliberately not pinning or restoring the model, which the review comment also suggested. Auto-switch is opt-in, default off, and GGUF-only, so restoring would silently evict the model the user just loaded from a background worker, and comparing the configured name to the loaded id is fragile across variant suffixes and advertised aliases, so it would break working runs. Verified: 853 passed across the research/web/sandbox/chat-history/rag/inference backend suites. Eight of the nine new tests fail without the fix. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Make website-policy search reach the whole allowlist and refill past blocks for PR #7219 Two review findings on the website access policy. Domains past the site: filter cap were undiscoverable. The policy accepts up to 100 allowed domains and the prompt tells the model all of them are searchable, but scope_search_query always scoped to allowed[:8], so a source in the ninth or later domain could never be found, and an undiscovered URL cannot be fetched either. The cap itself is right, search engines stop honouring long OR chains, so the window now rotates by a hash of the query instead of being a fixed head. Every allowed domain is reachable across a multi-step run, the same query is always scoped the same way, and lists at or under the cap are unchanged. A page of blocked results returned nothing. The policy filters after the search while DDGS was asked for exactly max_results candidates, so if those happened to be disallowed the tool reported no results even when valid ones ranked just below, wasting a research step. Ask for a deeper pool when a policy is set and stop at max_results allowed entries. No policy means no over-fetch, so ordinary searches are unchanged. Verified: 2324 passed across the research/web/sandbox/chat-history/rag/tool backend suites. The 8 test_studio_api.py failures are pre-existing and need live OpenAI/Anthropic credentials; they fail identically with these changes stashed. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Only overfetch search results when the website policy restricts for PR #7219 Follow-up to 8be0b3699. Every run stores normalize_website_policy(...), which returns {"allowedDomains": [], "blockedDomains": []} and is truthy even when nothing is restricted, so the default unrestricted path asked DDGS for four times as many results on every step. That is pure added latency and timeout risk, since the filter passes everything and only max_results entries are returned either way. Test the domain lists rather than the dict. * Budget the whole research prompt against the loaded context for PR #7219 Only the synthesis evidence was budgeted, so the budget could not prevent the overflow it existed to prevent. Measured at head with a realistic prompt (40-source catalog, 12-step plan): the untrimmable scaffolding is about 7,900 chars and the conversation context adds up to 12,000 more. On a 4096-token context, which is the GGUF auto-fit floor and the transformers default, the synthesis request came to about 1.7x the window. Worse, _synthesis_evidence_budget computed usable_tokens = 0 at or below the 4,096-token reserve and then returned the 1,500-char floor anyway, so it added evidence to a prompt that already did not fit. The decision prompt had no context awareness at all: a fixed evidence[-60000:], roughly ten times a small window, on every step rather than once at the end. Overflow is not cosmetic here. It either silently truncates and degenerates the report, as the comment above these constants already warned, or fails the run, and a failed run is only recoverable via retry, which deletes every plan step, source and document source and nulls the report. Both paths now share _prompt_char_budget plus _trimmable_budget: each trimmable section is measured against what the rest of the prompt leaves, and can reach 0 instead of a floor, because a shorter report beats a destroyed run. Evidence is budgeted before the chat history, since the evidence is the report. Unknown context still keeps the full cap. At 4096 tokens the synthesis prompt now fits (0.6x). Below that it is still over, since a 40-source catalog alone exceeds the window; that needs a smaller maxSources, and the context box does accept values down to 128. test_synthesis_evidence_budget_tracks_loaded_context asserted the old floor at 2048 tokens, which is the bug, so it now asserts 0 and that the rest of the prompt counts against the same budget. Verified: 2325 passed across the research/web/sandbox/chat-history/rag/tool suites. The test_mcp_stdio_sessions failure is pre-existing and fails identically with these changes stashed. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Scope replayed research history to its own attempt for PR #7219 A retry deletes the previous attempt's research_plan_steps, research_sources and research_document_sources rows but keeps its events, and the SSE route attaches one live run snapshot to every event it emits, replayed history included. The step.completed payload carries only position, title, action, input and sourceCount, so that snapshot is the sole source of the excerpt and evidence. On any refresh after a retry, a replayed attempt-0 step was therefore matched against attempt-1's step row by position alone, and start_position resets to 0 after the delete, so the positions line up exactly. The preserved attempt-0 activity then showed attempt-1's excerpt and evidence, or lost them entirely when attempt 1 had not yet reached that position, under a banner that says previous activity is preserved. The run.started resumed branch read the same cross-attempt snapshot and spliced those activities out. Both are gated on the event's attempt matching the snapshot's retryCount, which is the same attempt scoping get_reasoning_text already applies server-side. The excerpt and evidence fall back to what the activity already holds, so a mismatch is non-destructive rather than blanking it. Verified: frontend contract 11 passed, tsc -b exit 0, and the new test fails without the store change. * Retry pre-stream failures in the research stream for PR #7219 _stream_completion serves planning, every decision step and synthesis, and it had no transport retry: a connection error or a 5xx raised before any response byte failed the durable run, and retry then deletes every gathered source, document source and plan step. _completion already treats the identical failures on the identical endpoint as retryable, so the two paths disagreed. This is partly a hole my own 689b06535 opened. After the no-model 400 the body is read, the connection returns to the pool, and _wait_for_local_model then sleeps for up to modelTimeoutSeconds before re-sending on the same client. Uvicorn's keep-alive is 5s, so that pooled connection is essentially always server-closed by then, and losing the has_expired race raises RemoteProtocolError, killing the run the wait existed to save. Also reachable via a read timeout waiting for headers under prompt-eval load. Retrying is safe only because nothing has been consumed at that point, and that is structural rather than a convention: with stream=True httpx returns on the response headers without calling aread(), and raise_for_status() reads no body, both verified against the installed 0.28.1. The handler is scoped to the inner try that ends at break, and _iter_stream_lines sits outside the loop with no path back to send, so a re-send cannot duplicate report text. Bounded and mirrors _completion: same >= 500 predicate, same 3 attempts, same 2**attempt backoff, lease and cancellation re-checked before re-sending. The transport counter and the model-wait counter are independent, so they cannot multiply. The response is closed before every re-send, as manual stream mode requires. Note HTTPStatusError is not a TransportError in httpx, so both are caught explicitly. Verified: 2330 passed. Five of the new tests fail without the fix; the three that pass either way are the invariants that must not change (fail fast on a real 400, never retry once the report has streamed, existing model-wait path). * Bound the planning prompt to the loaded context for PR #7219 Completes dc16598a4, which budgeted the decision and synthesis prompts but left planning unbounded. The question reaches the planner verbatim (a pasted document arrives here as-is) and the history is capped only at the fixed 12,000 chars, so on a small context planning could overflow before any plan was persisted, failing the run without doing any research at all. Same helpers as the other two paths. The question is budgeted before the history, since the question is the request. A test now asserts all three prompt paths hold their own context budget, so a fourth path cannot be added later without one. Verified: 2331 passed; the new test fails without the change. * Keep prompt inputs non-empty and fit the source catalog for PR #7219 Two follow-ups to the prompt budgeting, the first a regression I introduced in dc16598a4. The output reserve was a flat 4096 tokens, so on any context at or below that, including the documented 4096-token GGUF floor, the whole prompt budget came out as 0. Every trimmable section then sliced to nothing: planning_question became the empty string, so the planner never saw the request at all, and synthesis dropped all its evidence. Removing the old floor outright went too far; an empty prompt is worse than the overflow it was avoiding. The reserve is now capped at half the window, and the question and the evidence each keep a floor, since one carries the request and the other carries the answer. A truncated completion is recoverable, a confidently empty report is not. The source catalog was the one section still inserted whole. It holds up to maxSources entries with snippets persisted at up to 4000 chars each, so on a smaller context it alone could exceed the budget while the code responded only by zeroing the evidence and history. It is now fitted first, dropping whole entries from the tail rather than slicing mid-entry, because a half-truncated URL is worse than an absent one: the validator would strip it and the claim would be left uncited. Verified: 2333 passed. All three new tests fail without the change; the question now keeps 1072 chars at a 2048-token context and 4144 at 4096, where both were previously 0. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten Deep Research comments for PR #7219 Post-convergence comment pass over the 40 source files in the PR diff, limited to lines the PR itself adds so untouched upstream code in the same files is left alone. 15 files, 110 insertions, 141 deletions. The reduction is deliberately small. Almost every comment here records why something non-obvious is done, a measured result, a spec rule, or the exact bug it prevents, and those are worth more than the lines they cost, so nearly every edit is a same-meaning compression rather than a deletion. Kept in full: the GFM autolink citation for the URL trim, the catastrophic-backtracking note on _DOCUMENT_CITATION, the prompt-budget notes recording that a reserve at or above the context leaves nothing, the two measured site: filter findings, and the remount note on the activity panel key. Verified comment-only three ways: comment_tools.py reports 15/15 code-unchanged, and an independent ast.dump comparison with docstrings stripped shows zero of the 12 Python files differing. 421 backend tests and the 11 frontend contract tests pass, and the phrase the contract test asserts on is still present on one line. * Harden Deep Research model streams * Fit Deep Research decision prompts * Preserve Deep Research follow-up context * Redact composite credentials from research queries * Scale Deep Research UI typography * Address Deep Research refinement review * Harden Deep Research refinement edge cases * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen Co-authored-by: Daniel Han --- studio/backend/core/inference/tools.py | 156 +- .../core/inference/web_access_policy.py | 153 + studio/backend/core/rag/web_rank.py | 132 + studio/backend/core/research_runs.py | 2378 ++++++++++++++ studio/backend/main.py | 29 + studio/backend/routes/__init__.py | 4 +- studio/backend/routes/chat_history.py | 63 +- studio/backend/routes/research_runs.py | 463 +++ studio/backend/storage/research_runs_db.py | 1228 +++++++ studio/backend/storage/studio_db.py | 338 +- .../backend/tests/test_chat_history_routes.py | 29 +- .../tests/test_chat_history_storage.py | 67 + studio/backend/tests/test_desktop_auth.py | 1 + studio/backend/tests/test_middleware.py | 43 + studio/backend/tests/test_rag_retrieval.py | 82 + .../tests/test_research_runs_hardening.py | 934 ++++++ .../tests/test_research_runs_storage.py | 2903 +++++++++++++++++ .../backend/tests/test_web_access_policy.py | 265 ++ .../tests/test_web_fetch_extraction.py | 24 +- studio/backend/tests/test_web_rank.py | 135 + .../components/assistant-ui/markdown-text.tsx | 23 +- .../components/assistant-ui/rag-sources.tsx | 38 +- .../src/components/assistant-ui/sources.tsx | 38 +- .../src/components/assistant-ui/thread.tsx | 366 ++- .../components/markdown/markdown-preview.tsx | 23 +- studio/frontend/src/features/auth/index.ts | 1 + studio/frontend/src/features/auth/session.ts | 2 + .../src/features/chat/api/chat-adapter.ts | 296 +- .../src/features/chat/api/research-api.ts | 357 ++ .../frontend/src/features/chat/chat-page.tsx | 140 +- .../deep-research-composer-button.tsx | 241 ++ .../components/research-activity-panel.tsx | 985 ++++++ .../chat/components/research-message.tsx | 176 + studio/frontend/src/features/chat/index.ts | 5 + .../src/features/chat/runtime-provider.tsx | 86 +- .../chat/stores/chat-runtime-store.ts | 133 +- .../chat/stores/research-run-store.ts | 908 ++++++ .../src/features/chat/types/research.ts | 197 ++ studio/frontend/src/lib/safe-markdown-url.ts | 33 + .../test_deep_research_frontend_contract.py | 295 ++ 40 files changed, 13572 insertions(+), 198 deletions(-) create mode 100644 studio/backend/core/inference/web_access_policy.py create mode 100644 studio/backend/core/rag/web_rank.py create mode 100644 studio/backend/core/research_runs.py create mode 100644 studio/backend/routes/research_runs.py create mode 100644 studio/backend/storage/research_runs_db.py create mode 100644 studio/backend/tests/test_research_runs_hardening.py create mode 100644 studio/backend/tests/test_research_runs_storage.py create mode 100644 studio/backend/tests/test_web_access_policy.py create mode 100644 studio/backend/tests/test_web_rank.py create mode 100644 studio/frontend/src/features/chat/api/research-api.ts create mode 100644 studio/frontend/src/features/chat/components/deep-research-composer-button.tsx create mode 100644 studio/frontend/src/features/chat/components/research-activity-panel.tsx create mode 100644 studio/frontend/src/features/chat/components/research-message.tsx create mode 100644 studio/frontend/src/features/chat/stores/research-run-store.ts create mode 100644 studio/frontend/src/features/chat/types/research.ts create mode 100644 studio/frontend/src/lib/safe-markdown-url.ts create mode 100644 tests/studio/test_deep_research_frontend_contract.py diff --git a/studio/backend/core/inference/tools.py b/studio/backend/core/inference/tools.py index 5ae266bee0..d45fede89a 100644 --- a/studio/backend/core/inference/tools.py +++ b/studio/backend/core/inference/tools.py @@ -49,6 +49,9 @@ from loggers import get_logger logger = get_logger(__name__) _EXEC_TIMEOUT = 300 # 5 minutes +_RAG_SEARCH_SLOT = threading.BoundedSemaphore(1) +# Candidate multiplier when a website policy will filter the results after the search. +_POLICY_OVERFETCH = 4 _DISABLE_DNS_PINNING_ENV = "UNSLOTH_STUDIO_DISABLE_DNS_PINNING" # Splits the UI source-map from the result;
