PR #1309 plumbed user-scope into the session/message service layer so
non-owner / wrong-tenant lookups now surface as ErrSessionNotFound at
every entry point that goes through sessionRepo.Get. The handler-side
mapping, however, only existed in 4 of the 8 affected sites:
- handler/session/handler.go:GetSession ✓ already mapped (with `==`)
- handler/session/handler.go:UpdateSession ✓ already mapped (with `==`)
- handler/session/handler.go:DeleteSession ✓ already mapped (with `==`)
- handler/session/handler.go:BatchDeleteSessions ✓ already mapped (with `==`)
- handler/session/handler.go:ClearSessionMessages ✗ always 500
- handler/session/stream.go:ContinueStream session lookup ✓ (with `==`)
- handler/session/stream.go:ContinueStream message lookup ✗ always 500
- handler/message.go:LoadMessages (recent + before-time) ✗ always 500
- handler/message.go:DeleteMessage ✗ always 500
Result: a Contributor in tenant A asking for a Contributor B's session
messages got a 500 instead of 404 — the wire response leaked
"something is broken" rather than "you can't see this URL", which
breaks SDK / frontend axios interceptor error handling that keys on
HTTP status.
Two changes:
1. Add ErrSessionNotFound → 404 mapping to the 4 sites that lacked it
(ClearSessionMessages, ContinueStream's GetMessage, LoadMessages's
two paths, DeleteMessage).
2. Replace `err == errors.ErrSessionNotFound` with
`stderrors.Is(err, errors.ErrSessionNotFound)` everywhere. Sentinel
error comparison must use errors.Is so wrapped errors
(`fmt.Errorf("...: %w", ErrSessionNotFound)`) still match. Today no
service-layer caller wraps, but a future refactor that does would
silently turn 404s into 500s with no test catching it.
Tests:
- internal/handler/message_session_not_found_test.go covers the four
new mapping sites in handler/message.go (LoadMessages-recent,
LoadMessages-before-time, DeleteMessage) and pins the wrapped-error
behaviour with a dedicated regression test that fmt.Errorf("%w") a
sentinel must still be detected as ErrSessionNotFound. The bare
handler is hit through gin.Engine + middleware.ErrorHandler so the
response shape matches production exactly.
- PR #1309's existing service-level tests (session_user_scope_test,
session_test on the repository) still pass — this PR is a strictly
handler-layer follow-up.
The Agent ran a parallel context cache (Redis/in-memory) on top of the
messages table to feed multi-turn history into the LLM. That dual-write
caused subtle drift (e.g. compression diverging from DB, system-prompt
swaps lost on restart) and required a separate ClearContext path on
session/IM clear.
Make the messages table the single source of truth:
- Add service.LoadAgentHistory: rebuilds chat.Message history per turn
from the persisted messages, expanding AgentSteps into proper OpenAI
assistant_with_tool_calls + tool messages and replaying the canonical
final answer (with <think> blocks stripped). final_answer tool calls
are filtered to avoid duplicating the trailing answer.
- Make AgentEngine stateless across turns: drop ContextManager / sessionID
cache plumbing from the engine, agent service, and CreateAgentEngine
signature. The engine only uses sessionID for logging/event emission.
- Wire AgentQA to load history from DB on demand using HistoryTurns
(default 5) when MultiTurnEnabled, otherwise run with empty history.
- Delete the llmcontext package (ContextManager interface, Redis/memory
storage, factory) and the SessionService.ClearContext API path; IM
/clear and session message clear no longer need to invalidate cache.
Behavior preserved: KnowledgeQA-mode replay is unchanged (turns with
empty AgentSteps just produce the single canonical assistant message),
and Agent-mode turns now consistently see prior tool calls and results.
- Apply the session-list additions to the SQLite init migration (Lite build)
and make QueryPaged dialect-aware: LOWER(..) LIKE on SQLite, ILIKE on
Postgres, drop NULLS LAST on SQLite. Escape LIKE wildcards in the keyword
via the existing escapeLikeKeyword helper.
- SetPinned now returns rowsAffected so the handler can respond 404 on
unknown / unauthorized session IDs instead of a misleading 200.
- GET /sessions always returns the enriched shape (pin state + IM origin
fields) so the frontend never needs a second roundtrip; the dual-path
legacy branch in the handler is gone.
- Register pin routes with the wildcard name that matches each verb's
existing radix tree (POST :session_id, DELETE :id) and accept either
param name in the handler; avoids gin's "wildcard conflicts" panic.
- Drop the redundant [platform] prefix from IM session titles now that
the list renders a platform icon alongside the title; add unit tests
for shortID / buildUserSessionTitle / buildThreadSessionTitle.
- Frontend: remove the submenu search input and its i18n/keyword wiring
(search lives elsewhere in the app); pin icon uses the TDesign `pin`
glyph and inherits color so the active session turns green; optimistic
pin moves the item to the top of the list so it shows up at the top
of the Pinned group; IM text badge replaced by the platform SVG icons
from assets/img/im, desaturated by default and full-color on hover
or when the session is active.
Sessions today are a flat list ordered by updated_at. Two gaps showed up in
practice:
- Users cannot find specific chats as the list grows beyond a screen.
- IM-created sessions (WeCom/Feishu/Slack/...) are indistinguishable:
every title was "IM-<platform>" or "IM-<platform>-<username>" and the
list API hid the underlying im_channel_sessions mapping, so admins had
no way to tell which Feishu group a session came from.
Backend
- Migration 000039 adds sessions.user_id (owner), is_pinned, pinned_at
plus a composite index for the list query. Existing rows keep user_id
NULL and stay visible at the tenant level for backward compatibility.
- CreateSession now writes the caller's user_id from auth context.
- GET /sessions accepts keyword / source / agent_id. When any filter is
set, the response switches to enriched items that LEFT JOIN
im_channel_sessions and expose im_platform / im_chat_id / im_thread_id
/ im_user_id / im_agent_id / im_channel_id. No filters => legacy shape,
existing clients unaffected.
- Ordering: is_pinned DESC, pinned_at DESC NULLS LAST, updated_at DESC.
- POST/DELETE /sessions/:id/pin for user-scoped pin/unpin.
- IM session titles: "[platform] <user|chat|thread>" with short ID
suffixes so group/DM/thread sessions are visually distinct without
needing a round-trip to fetch a display name from the IM adapter.
Frontend
- Search input debounced at 300ms drives the keyword filter.

with a pin icon and a pin/unpin entry in the per-chat dropdown.
