* feat(models): add declarative reasoning capability contract (#5073)
Introduce an optional per-model `reasoning:` block beside the legacy
`supports_thinking` / `supports_reasoning_effort` booleans. It declares
thinking availability (unsupported | optional | required), the accepted
effort values with aliases, default, and serialization path, the payload
dialect, and the reasoning-history requirement. When present the booleans
are derived from it and contradictory profiles fail at config load.
`deerflow.models.reasoning` normalizes legacy and declared profiles into
one immutable contract and resolves every caller's generic request against
it. `create_chat_model` is the single enforcement point: required-thinking
models never receive a synthesized disable payload, unsupported effort
values never reach the provider, and the dialect synthesizes the on/off
payload when no template exists. Legacy profiles keep the historical path
byte-for-byte. The lead agent and subagent descriptor resolve the same
policy first so run metadata reports effective values.
`/api/models` and `DeerFlowClient` project the contract as `reasoning`;
the frontend derives mode clamping and effort choices from it through
`core/models/reasoning.ts`, and user preferences accept provider-specific
effort tokens. The setup wizard's Z.AI GLM-5.3-Flash profile migrates to
the contract, restoring its low/high/max effort control.
* docs(models): move the reasoning contract guidance into models/AGENTS.md
backend/AGENTS.md sits within 46 bytes of the 96 KiB effective-chain hard
limit for the middlewares, runtime, sandbox, and subagents guides, so the
new section pushed scripts/check_agent_guidance.py over it. The models
guide is the nearest file for the factory and the contract module, and
its chain has ample room.
* fix(models): address review on the reasoning contract
- vLLM dialect: the enable path now mirrors whichever chat_template_kwargs
switch the template declares, like the disable path already did, so a
template using the older `thinking` key no longer also grows
`enable_thinking`.
- Validate operator-supplied effort values at `effort.path` inside
`when_thinking_enabled`, `when_thinking_disabled`, and the `thinking`
shortcut against the contract, not only the profile-level value; they are
forwarded when the caller chooses nothing, so the "unknown values never
reach the provider" guarantee now holds for them too.
- Constrain `effort.path` to dotted identifiers and reject single-segment
paths that would replace a whole mapping (`extra_body`, `thinking`,
`model_kwargs`, `default_headers`, `default_query`).
- Z.AI GLM-5.3-Flash profile: `default: high` instead of `max`, because the
default also governs summarization, title generation, and subagent calls
that never choose an effort; `max` stays selectable. Documented in the
config example, the configuration manual, and the design note.
* fix(models): close reasoning contract review gaps
* fix(models): preserve native Ollama reasoning config
* fix(models): keep native reasoning strings and project reasoning into the descriptor
- `ModelConfig.reasoning` also accepts the level string ChatOllama takes
for gpt-oss style models (`low` / `medium` / `high`); the factory forwards
both the boolean and the string on the legacy path, so profiles that
passed `reasoning: high` through before the contract field existed keep
loading and keep sending it.
- The assembly descriptor no longer excludes `reasoning` from
`model_parameters`: the native ChatOllama value and a declared contract's
dialect/history/effort change the request payload, so they now move the
assembly fingerprint.
- e2e: the sidecar spec pinned the pre-contract body where a model without
effort control still received `reasoning_effort: minimal`; the preset is
now dropped for such models (the Gateway discarded it anyway), so the
assertion expects the key to be absent.
* feat(settings): persist account preferences across browsers
* docs(settings): scope preference guidance to user persistence
* fix(settings): preserve SSR and fence custom-agent defaults
* test: include user persistence in scoped guidance inventory
* fix(settings): sync explicit edits and preserve local tab updates
* fix(frontend): harden artifact and markdown rendering
* fix(#4117): restore allow-scripts for scroll-restore, fix citation XSS bypass
willem-bd identified these issues:
1. [REGRESSION] sandbox removed allow-scripts which broke HTML artifact
scroll-restoration — the injected postMessage script could not run.
The prior config (allow-scripts allow-forms without allow-same-origin,
i.e. opaque origin) was already safe. Restored with corrected comment.
2. [XSS bypass] CitationLink rendered <a href={href}> directly before
isSafeHref ran, so prompt-injected [citation:x](javascript:...)
bypassed the safety check. Moved citation block after the guard.
Also:
- Added mailto: and tel: to SAFE_HREF_PROTOCOLS
- Kept anchor-only attributes off the <span> fallback (React DOM warning)
Note: the loadMessages re-throw originally in this commit was dropped
during the rebase — upstream #4065 rewrote useThreadHistory as a
TanStack useInfiniteQuery that already surfaces fetch failures.
* test(e2e): update sandbox assertion to match allow-scripts allow-forms
The artifact preview iframe's sandbox was restored to 'allow-scripts allow-forms'
for scroll-restoration. Update the E2E test to expect the corrected value.
* fix(#4117): address review — ArtifactLink XSS guard, urlOfArtifact sandbox e2e
- Apply the isSafeHref guard to ArtifactLink (artifact-link.tsx) so a
prompt-injected javascript:/data: href in a .md artifact preview cannot
reach a real anchor in the main document, matching the guard in
createMarkdownLinkComponent.
- Add an e2e asserting the urlOfArtifact iframe (non-code
browser-previewable files like PDF) keeps its empty sandbox.
Note: the loadMessages error-surfacing changes originally in this commit
were dropped during the rebase — upstream #4065 rewrote useThreadHistory
as a TanStack useInfiniteQuery whose queryFn already throws on
!response.ok and surfaces the failure via a toast.
* fix(frontend): let write_file non-code previewable artifacts render in sandboxed iframe
When a write_file artifact such as PDF is clicked in chat, the component receives a path that forced isCodeFile=true, hiding the sandboxed iframe behind the code editor. Now non-code browser-previewable files are detected early so the sandboxed iframe renders correctly.
Fixes the E2E test: renders sandboxed iframe for a browser-previewable non-code file.
* fix(#4117): align PDF artifact route pattern with convention (drop /mock/ prefix)
The test used /mock/api/threads/... for the PDF artifact content route,
but the urlOfArtifact helper generates /api/threads/... (without /mock/)
when isMock=false. The other tests (e.g. presented artifacts) already use
the correct /api/threads/... pattern.
* test(frontend): add render-level coverage for unsafe markdown/artifact links
- Render MarkdownLink and ArtifactLink via renderToStaticMarkup and
assert an unsafe javascript: href produces a disabled <span> (never an
<a>), including through the citation-labelled branch, and that safe
https hrefs render hardened anchors (target=_blank, rel=noopener).
- The new ArtifactLink render test caught the unsafe href leaking onto
the fallback <span> through the {...rest} spread; drop the spread in
both span fallbacks so anchor-only attributes (href/target/rel) and
react-markdown's node prop never reach the span.
- Cover mailto:/tel: in the isSafeHref unit cases and fix the stale
SAFE_HREF_PROTOCOLS docstring that still claimed http/https-only.
* fix(frontend): route the agent save-hint through the safe localStorage facade
Export safeLocalStorage from core/settings/local and use it for the
agent-create save-hint read/write so blocked browser storage (Safari
private mode, strict containers, embedded WebViews) cannot throw from
the effect. core/agents/feature-cache.ts already guards its
localStorage access with try/catch, so settings + agent pages are now
consistently best-effort.
* fix(frontend): allow scheme-less relative markdown links in isSafeHref
