fix(gateway):unify thread id validation (#4589)
* fix(gateway): unify thread ID validation at the API boundary
Thread ID entry points accepted arbitrary strings while downstream
consumers (filesystem paths, Kubernetes Provisioner, JSONL event store)
each enforced different character restrictions, so invalid IDs were
persisted first and only failed later during sandbox/workspace init.
Centralize validation in deerflow.utils.thread_id (pattern
^[A-Za-z0-9_-]{1,64}$): validate at routers, RunCreateRequest,
scheduler dispatch, paths.py, JSONL store, embedded client, and align
the Provisioner pattern (pinned by a parity test). UUIDs are still
generated only when no ID is supplied; caller-supplied opaque IDs stay
supported.
Deliberate exceptions: DELETE /threads/{id} keeps str as the legacy
cleanup escape hatch (filesystem cleanup guarded), read-only
client.get_thread stays unvalidated, and scheduler rows with legacy
invalid IDs record a failed dispatch instead of raising out of the
poll loop.
* docs: document canonical thread ID contract
README: caller-supplied thread IDs need not be UUIDs; the canonical
pattern and per-endpoint behavior. AGENTS.md: the shared
deerflow.utils.thread_id contract, its enforcement boundaries, and the
legacy-ID escape hatches.
* fix(gateway): close thread ID validation gaps at remaining entry points
Follow-up to the canonical thread ID contract: a full audit found the
uniform-422 coverage only reached about half of the thread_id surfaces.
- routers: 18 routes still took a bare thread_id: str — 13 in
thread_runs.py (including the five messages/events/workspace-changes
reads that returned 500 on the JSONL event store vs 404/empty on the
DB store), 4 read routes in threads.py, and the suggestions route
flagged in review. DELETE /api/threads/{id} keeps str as the declared
legacy-cleanup escape hatch.
- client: upload_files/delete_upload/list_uploads/get_artifact now
validate up front, fulfilling the RFC's 'all mutating entry points'
clause (get_thread stays unvalidated as the declared legacy read path).
- tui: the /resume literal-ref fallback validates against the canonical
contract and reports a descriptive error instead of failing deep in
the client.
- scripts/support_bundle.py: replace the drifted dot-allowing pattern
with a byte-identical copy of THREAD_ID_PATTERN (kept local so the
script still runs with a broken venv).
* test(gateway): guard the canonical thread ID contract against regressions
- test_thread_id_route_contract.py: static AST sweep asserting every
route handler with a thread_id parameter annotates ThreadId
(whitelist: the DELETE escape hatch), plus a runtime sweep hitting
all 44 thread_id routes with a non-canonical ID and asserting a 422
that names thread_id, plus a websocket upgrade-rejection case.
- test_thread_id_validation.py: client entry-point validation,
support_bundle pattern parity, and TUI literal-ref fallback tests.
- Align two tests that encoded the old contract (dotted IDs).

feat(browser): add agentic browser control (#4187)
* feat(browser): add agentic browser control
* fix(frontend): format browser view changes
* fix(browser): keep browser optional and isolate sidecar layout
* fix(browser): address PR review security and IME findings
- Nginx: add a browser-stream WebSocket location before the generic
/api/threads regex so Live upgrades instead of downgrading to HTTP
(both nginx.conf and nginx.local.conf).
- Ownership: require an existing owned thread for the WS stream and REST
navigate, and tear down the browser session on thread deletion so a
later caller cannot reuse a retained page/cookies by guessing the id.
- SSRF: enforce the URL policy at the browser request boundary via a
context-level route guard covering redirects, popups, iframes, and
subresources (skipped for CDP-attached Chrome).
- IME: skip key forwarding while a composition is active so confirming a
CJK candidate with Enter no longer submits the remote page form.
Adds regression tests for the request guard, session teardown on delete,
and the composing-Enter key decision.
* fix(frontend): smooth streaming in long tool threads
* Revert "fix(frontend): smooth streaming in long tool threads"
This reverts commit f0462516eabe77f138d4027ea1c714fb226683cf.
* fix(browser): address review security and lifecycle findings
- Reject cross-origin WebSocket upgrades on the live browser stream
(Origin allow-list reuse of CORS/same-origin helpers) to close a
WS-CSRF hole, and fail closed when the ownership store is absent.
- Warn when a CDP-attached session runs with the SSRF request guard
off, and drop the unreachable CDP screencast teardown dead code.
- Read browser session launch config from a single canonical source
(browser_navigate) so it is deterministic regardless of call order.
- Bound per-thread Chromium accumulation with idle-timeout eviction
and an LRU max-sessions cap.
- Reset the Live reconnect counter on a successful open so the stream
can't permanently stall after the cumulative attempt cap.
* fix(frontend): reduce long tool thread render stalls
Reuse stable historical message groups during streaming, defer heavy Markdown and browser previews, and lazy-decode message images.
* fix(browser): keep live control responsive during continuous input
Why: Manual browser control felt laggy — a physical click ran the remote
Playwright click three times and each non-move input synchronously awaited a
JPEG screenshot, so events queued behind capture (queue wait up to ~237ms).
The first async attempt used a trailing-edge debounce, which froze the visible
page until a wheel/keyboard gesture stopped ("scroll finishes, then it jumps").
What:
- Frontend forwards one `click` per physical click instead of also emitting
`down`/`up`, so the remote page is not clicked twice per gesture.
- Backend detaches live-frame capture from input dispatch: non-move actions
start a rate-limited background refresh loop (leading frame + bounded cadence)
that keeps emitting frames while input continues and never blocks dispatch.
- Add regression tests: input dispatch no longer awaits the screenshot, rapid
inputs coalesce, and continuous input keeps refreshing before it stops.
Scenarios: Verified in the live Browser panel — a single click completes in
~57ms (was blocked behind a 171ms capture), and a 1.14s sustained wheel gesture
renders ~7 frames throughout the scroll instead of one frame after it ends.
* fix(browser): harden worker and session lifecycle
* fix(browser): address latest review feedback
* fix(frontend): preserve optimistic new-chat message
* test(e2e): preserve mocked message run ids
* fix(browser): address capability review feedback
