Add unit coverage for the StageInstructions custom deserializer: plain-string
shorthand, full object with instructions+template, unknown-field skipping, and
both forms coexisting on one WikiPageTypeDef (backward compatibility).
Jackson treated the @JsonCreator factory method as a properties creator
(matching the 'instructions' parameter name to the JSON field), not a
string/delegating creator, so plain-string values still failed at runtime
with "no String-argument constructor/factory method".
Replace with @JsonDeserialize + StdDeserializer that explicitly checks
VALUE_STRING vs START_OBJECT tokens, handling both shorthand strings and
full {instructions, template} objects.
- resolveAgentBasePath: the relative-override branch now normalizes the
resolved path and rejects values that escape the workspace root via "../"
(the absolute branch already did this), keeping attachment/media/tool I/O
contained when an agent's workspaceBasePath is a relative override.
- cleanAttachmentFiles: return early on a null/blank conversationId so a bare
upload root can never be walked and deleted wholesale.
- Translate the chat-upload Javadoc/comments to English (cleanAttachmentFiles,
BaseAgent image-path resolver) per code style.
- Add a resolver test for the relative-override escape fallback.
Strict OpenAI-compatible providers reject the /chat/completions request
with HTTP 400 when an assistant message in history carries a tool call
whose function.arguments is not parseable JSON. Normalize blank or
non-JSON arguments to "{}" at the send chokepoint so streaming,
history-replay, and older-persisted tool calls all stay well-formed.
SsoService / SsoStateService / SsoController / SsoProviderRegistry were
unconditional component-scanned beans, but their configuration
(SsoProperties) is only registered by the conditional auto-configuration.
With SSO disabled (the default) the services were still instantiated and
startup failed: "required a bean of type SsoProperties that could not be
found". Gate the four beans on the same mateclaw.sso.enabled=true
condition so the SSO stack loads as a unit — disabled = no beans and no
exposed endpoints; enabled = the auto-configuration provides SsoProperties
and everything wires.
Verified: backend starts clean with SSO disabled (default).
- Replace inline fully-qualified names with top-of-file imports across
SsoService / SsoStateService / FeishuSsoProvider (ObjectMapper, Autowired,
Map.of, Date, DuplicateKeyException, Mac, URLEncoder) per code style.
- createSsoUser: roll back the freshly inserted user on any non-duplicate
identity-insert failure, preventing passwordless orphan accounts. The two
inserts share no transaction — the method is self-invoked and the enclosing
callback performs a network call, so a method-level @Transactional would not
apply; an explicit rollback in the catch is the correct guard here.
* feat(sso): feishu OAuth2 single sign-on (ISSUE #405 P0)
Implements the SSO design (ISSUE #405) with feishu as the first IdP
and a generic OAuth2 provider abstraction for future dingtalk/wecom
extensions. SSO is disabled by default — existing deployments are
unaffected until mateclaw.sso.enabled=true.
Backend:
- SsoProvider interface + SsoUserInfo record: generic IdP abstraction
- FeishuSsoProvider: OAuth2 authorization-code flow (app_access_token
with Caffeine cache → user_access_token → user info). apiBase switches
between feishu.cn / larksuite.com by domain config.
- SsoProviderRegistry: conditional registration, lists enabled providers
- SsoStateService: HMAC-signed OAuth2 state + self-contained bind_token
JWT, both persisted to sso_state DB table for multi-node correctness.
State is one-time-consumable (conditional UPDATE), bind_token jti
anti-replay via PK insert. Hourly ShedLock purge (LambdaQuery + Java
time, works on all 3 dialects).
- SsoService: authorize/callback/bind, user mapping (union_id first →
external_id fallback), auto-create with concurrent idempotency
(DuplicateKeyException → rollback orphan user → re-query), link-only
mode issues bind_token for existing-account binding.
- SsoController: 4 endpoints (/providers, /authorize, /callback, /bind)
all permitAll.
- V159 migration (h2/mysql/kingbase): mate_user_external_identity,
sso_state, ALTER mate_user.password NULL (SSO-only users).
- AuthService: generateToken promoted to public; login() guards
password=null (SSO-only users cannot password-login).
- SecurityConfig: /auth/sso/** added to permitAll whitelist.
- LoginRateLimitFilter: expanded to cover /auth/sso/bind (brute-force
surface equivalent to /auth/login).
- application.yml: mateclaw.sso.* config block (all env-var driven).
Frontend:
- Login.vue: dynamic SSO buttons (only shown when providers configured),
OAuth2 callback detection (?sso=callback), link-only bind dialog,
shared applyLogin flow (localStorage + workspace + route).
- api/index.ts: ssoApi (providers, authorize, callback, bind).
Tests: SsoStateServiceTest (11) — state issue/verify/replay/tamper,
bind_token issue/verify/anti-replay/garbage. Regression: PAT (23) +
Approval resolve (13) all green.
Not in scope (P1/P2): link-only bind/unbind management endpoints,
user enable/disable endpoint, dingtalk/wecom providers, admin SSO
config page. Workspace assignment for auto-created users remains a
product decision (design doc §12 item 2).
* fix(sso): self-review fixes — P0 security + P1 quality
P0-1 BindRequired serialization: replaced the R.fail(200, Map.toString())
hack with a structured SsoCallbackResponse record. Controller no longer
catches an exception for a non-error path; frontend reads bindRequired
flag directly instead of regex-parsing a stringified map.
P0-2 createSsoUser unbounded recursion: added a retry flag — second
DuplicateKeyException (extreme race where identity was concurrently
deleted) now throws a 503 instead of recursing to stack overflow.
P0-3 state TTL not enforced: verifyState's conditional UPDATE now
includes created_at > cutoff, so a state unused for 5+ min is rejected
at consumption time, not just at the 1h purge. Without this the 5-min
window was advisory only.
P1-5 SsoStateService unused ObjectMapper: removed dead injection.
P1-6 audit JSON string concat: replaced with ObjectMapper serialization
(provider/externalId no longer risk breaking the JSON structure).
P1-7 LoginRateLimitFilter shared counter: documented the intentional
decision that login + bind share a per-IP counter (same brute-force
surface) with guidance on switching to per-path if finer isolation
is needed.
* feat(webchat): add approval resolve + replay for API-Key channel (ISSUE #413 P1)
Before this, a WebChat (API-Key) channel that hit a ToolGuard-protected
tool parked the turn in a pending approval the visitor could never
clear — it hung for 30 min until the GC timeout and the turn was
wasted. This PR closes the loop, mirroring the web ChatController.
A1 — no code change. tool_approval_requested already reaches the SDK
via ToolExecutionGuardHelper's streamTracker.broadcastObject (direct
SSE push, bypassing the StreamDelta path). Adding it to
forwardVisitorEvent would double-deliver; the default-drop is correct.
A2 — new /sessions/approve and /sessions/deny REST endpoints. Auth is
the existing visitorToken + conversationId ownership guard; the actor
is webchatUsername(visitorId), which resolves the 'no MateClaw
username' blocker noted in the old stopSession javadoc. Both broadcast
tool_approval_resolved so the SDK clears its banner in real time.
A3 — approve returns an SSE stream: resolveAndConsume (atomic DB +
metadata + memory), restoreChatOrigin (recovers the webchat origin
captured at createPending), then chatWithReplayStream replays the
tool call and continues the turn. Replay may re-trigger approvals,
which the existing tool_approval_requested direct push handles.
A4 — stopSession now sweeps pending approvals (denyAllByConversation)
and broadcasts each resolution, so stopping a stream no longer leaves
approvals lingering for the GC.
Tests: WebChatApprovalInteractionTest (7) — deny resolves + broadcasts,
deny auth/ownership guards, idempotent unknown-pending, stop sweep
clears pending, stop no-op when nothing pending.
Regression: WebChatStopStreamTest (5), WebChatArchivePinTest (6),
WebChatSchemaFieldsTest (5), WebChatWikiPageListTest (8),
ApprovalWorkflowServiceResolveTest (13), GcTest (7), RecoveryTest (7).
* fix(webchat): IDOR guard + SSE hang fix (PR #415 review)
Addresses all review feedback from mateaix:
P0 IDOR (security): /sessions/approve and /sessions/deny accepted a
client-supplied pendingId without cross-checking it belonged to the
caller's conversation. A visitor could resolve / replay another
visitor's guarded tool call. Fix: getPending(pendingId) then assert
conversationId matches before resolving. Added getPending delegate on
ApprovalWorkflowService so the webchat controller (which holds the
workflow facade) can do the precise lookup.
SSE hang: approveSession's already-resolved / error branches broadcast
'done' before streamTracker.register/attach, so the event had no
subscriber and the SSE hung to the 10-min timeout. Fix: register+attach
first, then resolveAndConsume. Removed the now-duplicate register/attach
in the replay branch.
Tests: +2 IDOR cases (cross-visitor pendingId rejected 404; mismatched
pendingId rejected 404). denyResolvesPending now asserts via getPending
(findPendingByConversation returns the earliest pending, polluted by
cross-test map state). denyUnknownPendingIsSafe updated to expect 404
(no longer leaks pendingId existence). Isolated IDOR victim/attacker
visitor IDs to avoid cross-test conversationId collisions.
Regression: WebChatStopStreamTest (5), WebChatArchivePinTest (6),
ApprovalWorkflowServiceResolveTest (13), GcTest (7), RecoveryTest (7).
* style(webchat): use simple ChatOrigin name in approveSession (PR #415 review)
Reviewer flagged fully-qualified inline types (ResolveOutcome was fixed
in the prior commit; ChatOrigin was missed). Add the import and switch
the 3 FQN references in approveSession to the simple name, matching the
ResolveOutcome cleanup. chatStream's pre-existing FQN usages are out of
this PR's scope and left untouched.
Before this, a workflow await_approval step whose approverChannels
pointed at feishu/wecom was effectively dead for IM interaction. Even
after PR #414 (B1) pushed the notice to the IM group, clicking the
card's Approve/Deny buttons did nothing useful:
- Identity check (requester==clicker) failed-closed: wf- approvals
have userId=null (system-initiated), so every click was rejected.
- Even if it passed, the synthetic /approve injection was a dead end:
the router routes by conversationId, but wf- ids use a synthetic
workflow:run:{runId} key that no IM conversation matches, so
findPendingByConversation returned null and the /approve was fed
to the LLM as plain text.
B3 fix: both ToolGuardCardHandlers now detect the wf- prefix and
resolve inline (approvalService.resolve), bypassing the synthetic
injection entirely. The WorkflowApprovalResolvedEvent published
inside resolve is picked up by ApprovalResumeBridge (activated in
PR #414 B2), which resumes the paused run. This mirrors the Web /
WebChat resolve path (PR #415).
Identity policy: any audience member may resolve a wf- approval.
The card only reaches channels declared in await_approval's
approverChannels, so whoever sees it is a designated approver.
Regular tool approvals keep the strict requester==clicker guard.
Tests:
- wecom ToolGuardCardHandlerTest: +2 wf- cases (inline resolve, no
synthetic injection; already-resolved renders expired). Existing 6
cases updated for the new 3-arg constructor.
- feishu FeishuCardDispatcherTest: updated for the new factory
constructor signature.
Regression: ApprovalWorkflowServiceResolveTest (13), GcTest (7),
RecoveryTest (7), feishu dispatcher (4), button value (7),
renderer (3+3) — all green.
Two P0 fixes from ISSUE #413 — both address workflow await_approval
approvals that silently failed in production:
B1 — AwaitApprovalStepAdapter now dispatches the approval notice to
every channel in approverChannels that carries a target. Previously
approverChannels was write-only metadata: a workflow that declared
["feishu:oc_xxx"] silently dropped the notice and the IM group never
learned an approval was waiting. Element format is "channelType"
(no push, operator uses admin console) or "channelType:targetId".
Each channel failure is logged and skipped — it must not fail the step.
B2 — requestWorkflowApproval now registers the wf- approval into the
in-memory map via registerRecovered. Previously it only did
approvalMapper.insert, so getPending("wf-...") returned null,
performResolve short-circuited at the not-pending guard, the
WorkflowApprovalResolvedEvent was never published, and
ApprovalResumeBridge was dead code. With this fix, resolving a wf-
approval walks the full two-phase contract and the bridge fires.
Tests:
- WorkflowApprovalResumeBridgeTest (3): map registration, event
publish on resolve, safe no-op for unregistered wf- ids.
- AwaitApprovalNotifyTest (2): targeted channels dispatched, bare
"web" skipped, channel failure non-fatal.
Regression: ApprovalWorkflowServiceResolveTest (13), AwaitApprovalRuntimeTest (3),
DispatchChannelRuntimeTest (3), GcTest (7), RecoveryTest (7) — all green.
Add an async export feature on the Dashboard page -- global admins can
generate and download a multi-sheet operational data report (.xlsx
packaged as .zip). The export covers 9 sheets:
1. Overview - interval KPIs, system snapshot, 7-day trend, period comparison,
model details (configured providers only), agent activity ranking top 10
2. Token Usage - daily breakdown by runtime_provider with avg tokens/msg
3. Skill Stats - skill list with usage count, last-call time, bound agents
4. User Stats - per-(workspace, user) aggregated tokens, duration, last active
5. User Conversations - detail rows pairing user-asst messages
6. Security and Audit - unified view across 6 sources (guard rules, audit logs,
approvals, grants, config, business audit events)
7. Channel Stats - per-channel conversation count, tokens, unique users
8. Model Config - enabled plus API-key-configured models with parameters
9. Cron Jobs - execution records with duration and token usage
Backend highlights:
- generate/progress/download endpoints guarded by PreAuthorize hasRole ADMIN
- single AtomicBoolean lock (409 when busy), 90-day frontend cap, 5-min deadline
- metadata-based tool-call counting, deleted=0 filtering everywhere
- value label mapping (chat to dialogue, TRUE to enabled, etc.)
- one-time downloadToken, file auto-cleanup after 24h or download
Frontend highlights:
- SVG ring progress bar with smooth dashoffset transition plus slow rotation
- visibility gated by workspaceStore.isGlobalAdmin (v-if on button)
- 1-second polling driving progress state machine (idle/generating/done)
- Element Plus date-picker (30-day default, 90-day max)
- explicit SecurityConfig authorization for /swagger-ui*, /v3/api-docs*, /webjars/**
- public for local/default profile; admin-only (ROLE_ADMIN) by default in production DB profiles
- override via MATECLAW_OPENAPI_EXPOSE_UI; add RANDOM_PORT integration tests and docs
execute_code (bash/sh/shell) bypassed the workspace boundary guard, so shell
code run through it could read/write/delete paths outside the workspace sandbox
(e.g. cat /etc/passwd) while the same paths were blocked for read_file and the
shell tools. Bring execute_code under the guard (scan only shell-language code,
report the code param), and trust the tool-result spill roots so a legitimate
spilled result stays readable. Adds regression tests.
- Remove mateclaw-ui/package-lock.json and yarn.lock. This is a pnpm
monorepo where pnpm-lock.yaml is the only lockfile; the npm/yarn locks
were stray duplicates. Add a .gitignore rule so they are not committed
again by mistake.
- SourceEvidenceLedger: reference Pattern/Matcher by their imported
simple names instead of inline fully-qualified names.
Backend (SourceEvidenceLedger):
- appendWikiSourceTable now normalizes existing source lines in-place to
canonical "[N] Title - section - page N" format instead of skipping them
- Added replaceSourceLine helper that matches a full source line by regex
and replaces it with the canonical form
- When source lines exist without a "来源：" header, automatically insert
one so the frontend preprocessor can locate the source table
Frontend (useMarkdownRenderer):
- Added data-citation-index / data-citation-title to DOMPurify whitelist
- Added preprocessWikiCitations preprocessor: parses the canonical source
table to build an index-to-title map, replaces [n] markers in the answer
body with clickable <a> links, and wraps entire source-table rows so the
full line is clickable
- Integrated into the render pipeline after wikilink substitution and
before Marked parsing
Frontend (useGlobalWikilinkClick):
- Extended the click delegation selector to match both .wiki-link and
.wiki-citation elements
- Title extraction falls back: data-citation-title || data-wiki-title
Tests: added three test cases for source-line normalization, idempotency,
and automatic header insertion
Live lifecycle board (grid<->board toggle) plus an assignee-swimlane plan
board that groups follow-up re-runs of one goal into a single xN card.
Custom right-side detail/goal panels with markdown output. Fixes plans
being persisted under the per-run trace id so the board actually populates.
Closes#385
The cherry-picked V154 used 'ALTER TABLE ... ADD COLUMN IF NOT EXISTS' for
MySQL — invalid on MySQL 8.0.x (a MariaDB-only extension) which aborts Flyway
at startup. Switch to the INFORMATION_SCHEMA + PREPARE guard the other MySQL
migrations use. Also change the KingbaseES column from SMALLINT to BOOLEAN to
match the Java 'Boolean wikiDisabled' field and the existing skills_disabled /
tools_disabled flags (vanilla PostgreSQL is strict about boolean vs smallint).
H2 (already BOOLEAN) is unchanged.
Issue #304. Operators who want an agent with NO knowledge base had no
way to express it: leaving the KB picker empty fell through to "inherit
workspace-wide" (every KB visible), so the agent ended up ingesting
every KB's context. This adds the same opt-out toggle that
skills_disabled (V126) / tools_disabled already provide.
Backend:
- V154 migration (h2 + mysql + kingbase): mate_agent.wiki_disabled
BOOLEAN/TINYINT/SMALLINT NOT NULL DEFAULT FALSE. Legacy agents stay
bit-identical.
- AgentEntity.wikiDisabled: Boolean field, @TableField("wiki_disabled").
- AgentBindingService.getBoundKbIds: short-circuit at the top —
wiki_disabled=true returns Set.of() regardless of binding rows. Mirrors
the precedence contract of getBoundSkillIds vs skills_disabled.
- AgentBindingService.setKbBindings: a non-empty save auto-clears a
stale wiki_disabled flag (same contract as setSkillBindings /
setToolBindings on their respective flags). Empty saves leave the flag
untouched — the UI toggle owns the bit, not the binding writer.
- AgentBindingServiceWikiDisabledTest: 5 cases covering all three
return states + the stale-flag auto-clear + empty-save no-op.
Frontend:
- Agents.vue KB picker: add the "此智能体不使用任何知识库" /
"This agent uses no knowledge bases" toggle, mirroring the skills /
tools picker layout. Tab badge shows "Off" when the toggle is on.
- types/index.ts: add Agent.wikiDisabled?: boolean.
- Save logic: when wikiDisabled is on, send an empty KB list (the
setKbs contract then leaves the flag alone server-side, exactly as
setSkills / setTools behave for their opt-out flags).
- i18n (zh + en): new strings for toggle label, hint, badge, and the
scope description shown when the toggle is on.
Stacked on top of #382 (which introduced AgentBindingResolver
.getBoundKbIds). No agent-runtime changes — wiki tools already degrade
cleanly when getBoundKbIds returns Set.of().
Add /wiki/pages row to endpoint table and a new "Wiki knowledge-base
reference ([[slug]] picker)" section explaining the directive-text
mechanism, query parameters, visibility rules (synthesis excluded,
100-page cap, KB-scope fallback), and curl examples (zh + en).
Follow-up docs for the wiki picker endpoint shipped in this PR.
Add GET /api/v1/channels/webchat/wiki/pages mirroring /skills, so
downstream integrators can build a [[slug]] picker UI that points the
LLM at specific wiki pages. The picker token format is the universal
Obsidian/Wikipedia wikilink convention; the LLM consumes [[slug]] via
the existing wiki_read_page(slug=...) tool, so no agent-runtime changes
are needed.
- AgentBindingResolver.getBoundKbIds(agentId): three-state mirror of
getBoundSkillIds. null = no rows (fall through to workspace-wide KBs),
Set.of() = explicitly scoped to zero KBs, non-empty = explicit scope.
- WebChatController.listWikiPages: API Key + visitorToken auth chain,
agentId workspace anti-escalation, visibility excludes pageType=
synthesis (LLM intermediate artifacts), 100-page cap forces keyword
filter, response carries only display-level metadata.
- WebChatWikiPageView DTO: kbId/kbName/slug/title/summary/pageType;
content/embedding/sourceRawIds deliberately stay admin-console-only.
- WikiTool.wiki_read_page @Tool description: document the [[slug]]
convention so the LLM treats each token as a wiki-page reference.
- WebChatWikiPageListTest: 8 cases covering happy path, keyword filter,
synthesis exclusion, anti-escalation, auth failures, cap behavior,
and the no-binding → workspace-wide fallback.
Closes#381.
Add /skills row to endpoint list table, note optional agentId on /stream,
and add a new "Skill invocation (slash picker)" section explaining the
directive-text mechanism with curl examples (zh + en).
Follow-up polish for the /skills endpoint shipped via PR #374.
- per-KB entity-type whitelist (config UI + persistence; empty = built-in defaults)
- entity graph: legend grouped by type with click-to-filter; nodes colored by type
- always show entity names on graph nodes (not only on hover)
- earthy categorical palette aligned to the app theme, shared by entity & page graphs
- theme-aware graph label color (resolve CSS var for canvas, light/dark correct)
- manual extract = full rebuild: idempotent force re-extraction + orphan pruning,
guarded against data loss on a fully-failed run
- regression test for force re-extraction; zh/en i18n
GET /api/v1/channels/webchat/skills?agentId=<optional>&visitorId=<required>
Headers: X-MC-Key + X-MC-Visitor-Token
Downstream systems integrating via the webchat SSE endpoint have no way
today to enumerate the skills a visitor can invoke — the existing
GET /api/v1/skills is JWT + workspace-role gated, unreachable from the
API-Key-authenticated webchat channel. Without a list, integrators
can't render a slash picker UI; visitors have to know skill slugs by
heart.
The new endpoint mirrors the /stream auth chain (resolveChannel +
verifyVisitorToken) and reuses AgentBindingResolver.getBoundSkillIds
to scope visibility. Only enabled skills explicitly bound to the agent
surface; agents with no explicit bindings return an empty list rather
than inheriting the global pool (the agent config stays the source of
truth for what surfaces in visitor UI). The agentId anti-escalation
guard from /stream is reused verbatim — an explicit agentId must
belong to the channel's workspace.
Returns WebChatSkillView (id / name / nameZh / nameEn / description /
icon). Deliberately omits SKILL.md content, configJson and
securityScanResult: those never leave the admin console.
Issue: #373
The previous notLike(column, "%:") form auto-wraps the value with extra %
on both sides AND escapes the user-supplied %, producing a %%:% pattern
that matches any id CONTAINING a colon — silently filtering out every
webchat:<key>:<visitor>, feishu:<chatId>, cron:<jobId> conversation from
the admin list / page. The frontend sidebar ends up empty.
Switch to notLikeLeft(column, ":") which only prepends the wildcard,
giving the intended NOT LIKE '%:' (does not end with a colon).
Strengthen the three malformedIdGuard tests to assert on the bound param
value ("%:" — ends-with colon) in addition to the SQL keyword, so this
regression cannot return silently. The assertions must call
getTargetSql() first to trigger MyBatis-Plus's nested-wrapper param
merge — getParamNameValuePairs() is empty on the parent until then.
conversationId ending in ":" (e.g. webchat:<key8>: with empty visitorId,
from older webchat versions) leaks into the admin console via the
'webchat:%' username LIKE, then 500/403s on open because the trailing ":"
makes some reverse proxies strip the path tail — landing a GET on the
@DeleteMapping variant of /{conversationId} (issue #369).
Add applyMalformedIdGuard — a NOT LIKE '%:' clause — to both listConversations
(lenient + strict overloads) and pageConversations so these rows never
surface. isConversationOwner already rejects unknown ids with 403, so no
change is needed on the direct-access endpoints; once the rows are out of
the lists, admin can no longer reach them.
The two existing strict/non-admin assertions changed from "no LIKE keyword"
to "no webchat:% param value" — applyMalformedIdGuard emits a NOT LIKE
itself, so the LIKE keyword is now present in every query.
Tests cover the guard on lenient, page, and strict paths.
Spring's default lets HttpRequestMethodNotSupportedException escape to the
catch-all @ExceptionHandler(Exception.class), surfacing as a 500 with a full
stack trace. Return a clean 405 so the client gets a structured R body and
the log stays at WARN.
This is also the second line of defence against malformed path segments that
confuse reverse proxies — e.g. a conversationId ending in ":" can make a
proxy strip the trailing path, landing a GET /api/v1/conversations/<id> on
the @DeleteMapping variant and triggering exactly this exception (issue #369).
Align the conversation list/page with the isConversationOwner cross-workspace
guard: only a global admin can open a webchat-owned conversation, so only
admins should see those rows. Previously listConversations / pageConversations
surfaced webchat principals to every authenticated user, who would then 403 on
opening them (list-vs-access asymmetry).
Also fixes ConversationServiceWebchatVisibilityTest, which still asserted the
pre-guard owner behavior and never mocked AuthService, so it threw NPE at
runtime once isConversationOwner started resolving the requester. The owner
matrix is covered by ConversationServiceOwnershipWorkspaceTest; this test now
pins the admin-gated list visibility for both admin and non-admin callers.
