Follow-up to #447. The generated-file link extraction accepted any
non-')' text before the path, so a paren-free javascript:/data: URL
embedding /api/v1/files/generated/<id> could be captured and bound to an
<a href>, enabling XSS on click. Adopt the scheme-restricted pattern
already used by SegmentSupersedeDetector and the channel adapters, on
both backend (ChatController) and frontend (useChat). Also replace the
inline fully-qualified Pattern/Matcher with imports and drop an unused
run-overview i18n key.

Extract generated-file download links from tool results — on the backend (persisted to message metadata for history) and on the frontend (live during SSE) — de-duplicate by URL, and render them as a Generated Files section with file-type icons and a rail badge.
The chat composables (useStickToBottom / useStream / useMessages / useTyping)
carried '参考 @agentscope-ai/chat …' attribution comments. That package is not
a dependency and is never imported — the lines were pure citation. Rewrite them
as objective functional descriptions so shipped code does not name external
projects.
- useChat.ts reconnectStream: cast the reused assistant message id to string
when calling updateMessage; the id is optional in the Message type, so the
raw value broke the vue-tsc build (TS2345, undefined not assignable).
- useStickToBottom.ts handleScroll: restore the block's indentation (it had
drifted to 1/3-space) and add a comment for the scroll-up release branch.
Verified: vue-tsc --noEmit passes; snowflake precision check clean.
Always-on memory (structured user/feedback blocks, PROFILE.md, MEMORY.md) is injected into every system prompt but only ever grew, inflating per-turn context over time. This adds deterministic size control across all always-on sources:
- Injection budget: cap the always-on structured block by total chars and per-type entry count, keeping the most-recently-updated entries (LRU by Updated date) and disclosing how many were omitted
- Nightly consolidation: a dedicated scheduled pass merges duplicate/stale user & feedback entries via the LLM, preserving each entry's original Updated date; runs per owner bucket (shared + personal) with a per-run cap and a never-grow safety guard
- File ceilings: deterministic backstop truncates PROFILE.md / MEMORY.md at a section boundary when a rewrite overruns its budget
- Manual trigger endpoint for the consolidation maintenance task
All knobs under mate.memory.*; covered by unit tests.
When SSE setup fails (e.g. workspace permission denied for shared channel
conversations opened from the web console), the failed turn is never
persisted on the backend. Two issues made the failure invisible to the user:
- The fallback errorInfo dropped data.message, so the inline retry card fell
back to the generic "请求过程中遇到了意外问题" template instead of the
actual reason. Carry rawMessage through, and lower the MessageBubble
display threshold from >8 to >3 chars so short-but-informative messages
(7-char Chinese / "Forbidden") aren't filtered out.
- The status-poll loop in useChat overwrote the local-only failed turn
with the server's "no message" view, erasing the inline retry card.
Skip the merge for turns that exist only locally and are in error state,
so the user can still see the failure and retry.
- Reconcile approval status atomically: DB row, message metadata, in-memory store
- Approve and deny both flip the tool-call card + timeline segment to a terminal
state on the gate message — no more orange spinner stuck after a decision
- Frontend hydrate matches by pendingId and reverse-converges to expired so a
refresh after server-side timeout / consume clears the banner without restart
- Stop sweep, GC timeout, and JVM restart all close the loop with consistent
state
- Remove the dead REST /approve endpoint + matching frontend client export so
there is only one resolve path to maintain
Three bugs surfaced when a non-admin workspace member opened the channel
admin page:
- vue-i18n "Invalid linked format" when '@' appeared in message strings
without the linked-format escape. Replaced literal '@' with vue-i18n v9
literal interpolation {'@'} in both zh-CN.ts and en-US.ts (6 strings:
QQ guide step3, accessControl requireMention/Tooltip).
- 403 from WorkspaceAccessInterceptor was being treated as 401 by the
axios interceptor and the chat SSE handler, clearing the token and
redirecting to /login. Split the two:
* 401 = authentication failure -> handleAuthFailure (logout)
* 403 = authorization failure -> keep session, surface to caller
Now a member who lacks workspace permission sees a toast instead of
being silently logged out.
- Two backend exception sites threw with the default code=500 for what
is semantically an auth/authz event, contradicting the codes returned
elsewhere for the same business event:
* AuthService.login() bad credentials 500 -> 401
* WorkspaceService.requirePermission() 500 -> 403
This aligns service-layer denials with SecurityConfig (401 for missing
JWT) and WorkspaceAccessInterceptor (403 for permission denied), so
the same business event always produces the same code.
The two tools-sync scripts ran on every startup and used H2 MERGE INTO
... KEY(id), which overwrites every column on existing rows. That
silently reverted UI-toggled `enabled` and was the proximate cause of
a recent WriteFileTool/EditFileTool outage.
They were also a strict subset of the fresh-install seed (data-zh.sql /
data-en.sql register all 19 builtins; the sync scripts only 16) and out
of date. Per-tool Flyway migrations (V3, V31) are already the canonical
'register a new builtin' path, so the sync layer was duplicated and
error-prone.
Delete both files and the runToolSyncScript() loader. Tool descriptions
shown to the LLM come from @Tool annotations in code, not the DB row,
so removing per-startup metadata refresh has no functional impact.
A bundle of stability fixes that all surfaced together while running
the same long-form generation task across multiple turns. Each one
addresses a distinct way the previous behavior silently dropped
content the user had already seen on screen.
1. Mid-turn narrative persistence (StateGraphReActAgent +
SummarizingNode). Intermediate ReasoningNode rounds and
SummarizingNode broadcast their content_delta directly to the
SSE channel for live display, but the StreamAccumulator only
received the final answer. After refresh the assistant message
showed only tool_call cards with no body text.
StateGraphReActAgent now also forwards STREAMED_CONTENT (already
set per round) as a persistOnly StreamDelta whenever it changes,
so every narrative chunk lands in the accumulator's content
buffer and gets written to mate_message. SummarizingNode now
writes its summary into the same key so summarize narratives
persist too.
2. Follow-up message queue, not dispose (ChatController#interruptStream).
Sending a new message while a turn was running called
requestInterrupt, which dispose()d the active Reactor chain mid
LLM call. That cancelled the in-flight generation, lost partial
tokens, and left the user staring at a half-finished bubble.
The endpoint now uses enqueueMessage in all paths, matching
the "wait for current turn, then run" behavior. The old
requestInterrupt API is kept for any future force-replace UI
but no caller routes to it.
3. Queued user message ordering (ChatStreamTracker.QueuedInput +
ChatController.startQueuedMessage). interruptStream used to save
the queued user message immediately, before the in-flight
assistant message finalized in doOnError. listMessages orders
by create_time ASC, so the queued user message ended up above
the assistant reply it was supposed to follow. QueuedInput now
carries contentParts; persistence is delayed to startQueuedMessage,
which runs only after Asst-N is on disk.
4. JVM shutdown flush (ChatStreamTracker @PreDestroy +
emergencySaveAccumulator). A mvn spring-boot:run restart used to
wipe in-flight turns: SSE emitter timed out, ShutdownHook fired,
HikariPool closed before doOnError could save. ChatStreamTracker
now exposes an emergency-save callback per RunState; ChatController
registers one per stream that snapshots the accumulator and
writes status="interrupted_shutdown". @PreDestroy walks active
runs, invokes the callback, then disposes. Spring's reverse-order
bean teardown keeps ConversationService and Hikari alive long
enough for the save to complete.
5. Observation thresholds for summarize (GraphObservationProperties +
application.yml). The previous total-chars threshold of 12 KB
triggered summarize after one or two RFC reads, costing a 40 to
80 second compaction LLM call per loop. Tuned to: total 200 KB,
single 16 KB, large-result 32 KB, rounds safety net 25. Java
field defaults reverted to the conservative original values so
application.yml stays the source of truth.
6. Frontend thinking segmentation (useChat.ts thinking_delta +
phase). Multi-round ReAct turns merged every reasoning + summarize
round's thinking into one segment, accumulating to 9 KB+ in a
single bubble. thinking_delta now uses findLast(running) so a
tool_call_started or phase transition closes the previous segment
and the next delta opens a fresh one. phase event also closes
running thinking/content segments.
7. Other small things bundled: removed a debug metadata-keys log
that flooded the log file with one line per stream chunk; fixed
three stale tests that didn't compile after earlier constructor
changes (WikiLogServiceTest, WikiOverviewSpliceTest,
WikiProcessingServiceLazyTest); added rfc-066 documenting the
unified message queue + priority refactor as the next logical
step on top of these stabilizations.
Verified end-to-end with multiple full sessions: a four-minute
generation that produced the expected docx and a follow-up enqueue
that ran cleanly after the previous turn naturally completed,
without the old "Disposable unavailable" interrupt path.
