+ * Appium/CEF backend was removed in #5478 precisely because CDP does not exist
+ * under Wry; the runner is a single `tauri-driver` WebDriver session against
+ * the native WebKit webview (`app/scripts/e2e-run-session.sh:14-15`,
+ * `app/test/wdio.conf.ts:10-14`), and the shell is
+ * `pub(crate) type AppRuntime = tauri::Wry` unconditionally
+ * (`crates/openhuman-app/src/lib.rs:131`). The stated blocker is gone.
+ *
+ * This is the one case in this slice that cannot be a Playwright spec. The
+ * claim is about the *shell's* policy: `external_navigation::init()`'s
+ * `on_navigation` hook returns `false` for any http(s) navigation of the `main`
+ * window that is not the app origin or the dev server, cancelling it and handing
+ * the URL to the OS opener (`crates/openhuman-app/src/external_navigation.rs:54-89`).
+ * A browser has no such hook, so a Playwright version would assert nothing.
+ *
+ * RU (`external_navigation_tests.rs`) proves `navigation_handoff` returns the
+ * right answer. It cannot prove the plugin is *installed on the main window in
+ * the shipping build* — a wiring regression (registered late, or on the wrong
+ * webview) passes every existing test while the main webview, which holds the
+ * app's IPC bridge, loads someone else's origin. That is a security boundary,
+ * not a UX defect, which is why it is worth a desktop spec of its own.
+ *
+ * ## No network leaves this machine
+ *
+ * The probe host is under `.invalid`, the TLD RFC 2606 reserves as guaranteed
+ * never to resolve. The assertion is that navigation did NOT happen, so the URL
+ * never needs to load; and when the policy works as intended it hands the URL to

+/**
+ * Credential channels — Yuanbao (10.1.5) and Email/IMAP-SMTP (10.1.6).
+ *
+ * Both are `api_key` channels: the user pastes credentials into the generic
+ * `ChannelSetupModal` and the core validates them against the channel's
+ * `ChannelDefinition`. Neither had a spec at any UI layer —
+ * `git grep -l 'yuanbao\|imap' app/test/e2e/specs app/test/playwright/specs`
+ * returned nothing — which is what matrix rows 10.1.5 ("No WDIO spec yet") and
+ * 10.1.6 ("WDIO connect-flow [is a] follow-up") record.
+ *
+ * ## What this asserts, and what it deliberately leaves to the Rust unit tests
+ *
+ * The Rust side already covers the *ops layer* for both channels:
+ * `channels/controllers/ops_yuanbao_email_tests.rs` and
+ * `ops/connect_email_config_tests_tests.rs` cover credential→config mapping,
+ * defaults, port/sender parsing, persist + disconnect and pre-network
+ * invalid-port rejection. Re-asserting any of that here would duplicate it.
+ *
+ * What no layer covered is the **RPC surface these channels are reached
+ * through**: that each one is in the definition table `channels_list` serves,
+ * that `channels_describe` returns the field set the setup modal renders its
+ * inputs from, and that connect→status→disconnect round-trips over the wire.
+ * A channel can be fully implemented in `ops` and still be unreachable if it
+ * drops out of `all_channel_definitions()` — `channels_connect` resolves the
+ * definition first (`tinychannels/src/backend.rs:208-210`) and fails with
+ * "unknown channel" before any of the covered code runs. Slack and WhatsApp are
+ * both in that state today; nothing caught it.
+ *
+ * Mirrors the C.1/C.2/C.3/C.4/C.8/C.9 shape of `telegram-channel-flow.spec.ts`,
+ * which is the house pattern for a channel lifecycle.
+ *
+ * No network: `api_key` connect stores credentials locally. The Yuanbao
+ * sign-token preflight and the IMAP login are not reached — this spec never
+ * supplies credentials that would pass validation into a live call, and the
+ * mock backend is the only server running.

+ * local-model debug panel outright, so every control the old case reached no
+ * longer exists — unskipping it would not have needed an Ollama server, it
+ * would have failed on the first `waitForText('Local model runtime')`. The
+ * spec was not waiting for a harness; it was testing deleted UI.
+ *
+ * That mattered beyond tidiness: `docs/TEST-COVERAGE-MATRIX.md` cited this file
+ * as the evidence for **3.1.1, 3.1.2, 3.2.1, 3.2.3** (all ✅) and **3.3.3.2**
+ * (🟡). Five rows rested on a spec that had never executed an assertion, and
+ * because the file *is* wired into the `system` suite it was collected,
+ * launched and reported as a pass every run. A skipped spec that four ✅ rows
+ * point at is worse than no spec: it reads as coverage from the matrix and
+ * costs a lane slot to produce nothing.
+ *
+ * # What this file asserts now
+ *
+ * The one claim about the local-model surface that is true, checkable on the
+ * desktop shell, and worth defending: **the legacy deep route is a redirect,
+ * not a dead end.** `settingsRouteElements.tsx` maps `local-model-debug` to
+ * `<Navigate to="/connections?tab=llm" replace />`, so a user following an old
+ * link, bookmark or doc lands on the page that replaced it. If that `Navigate`
+ * is dropped in a future settings-route refactor the route renders nothing and
+ * the failure is silent — a blank settings pane, no console error.
+ *
+ * The web lane asserts the same redirect
+ * (`app/test/playwright/specs/local-model-runtime.spec.ts`); this is the
+ * desktop-shell half, where the hash router runs inside the real Wry webview
+ * rather than a browser tab.
+ *
+ * `navigateViaHash` is deliberately not used: its `HASH_REDIRECTS` table does
+ * not carry this route, so it would wait for the wrong target hash and time
+ * out. Driving `window.location.hash` and polling for the settled value tests
+ * the app's own router rather than the helper's copy of the route map — which
+ * is the point, since a stale copy is exactly what this guards against.

+ * Drive a chat turn the way the product does, without touching the composer.
+ *
+ * Every turn in these specs goes out over `openhuman.channel_web_chat` — the
+ * same RPC `chatService.sendChatMessage` calls (`src/services/chatService.ts:1631`).
+ * Two reasons, and only the second is about a bug:
+ *
+ *  1. It separates what is under test from how the text got there. A spec about
+ *     stream routing or a parked gate should not fail because the composer
+ *     changed, and a composer regression should not be reported as a routing
+ *     one.
+ *  2. `ComposerTextBridge` used to chain a synchronous `setState` per keystroke
+ *     past React's nested-update limit, so an automated driver typing at speed
+ *     took the chat surface to its error boundary
+ *     (`src/features/conversations/components/AssistantUiChat.composerSync.test.tsx`).
+ *     That is fixed and pinned by a unit test, but nothing here needs to depend
+ *     on it staying fixed.
+ *
+ * The one thing the RPC cannot invent is `client_id`: the core routes the
+ * stream to the socket that id belongs to, so a made-up one runs the turn and
+ * delivers it nowhere this page can see. We read the live socket id out of the
+ * store (`src/store/socketSlice.ts`, exposed as `window.__OPENHUMAN_STORE__`),

+ * `guardrail-notice` — and the wiring gap that keeps it off screen.
+ *
+ * Family: `components/assistant-ui/elements/guardrail-notice.tsx`, mounted by
+ * `features/conversations/aui/ChatErrorNotice.tsx`. Zero e2e coverage before
+ * this spec, and the reason turns out to be structural rather than an
+ * oversight.
+ *
+ * **The card is unreachable on the product web-chat path today.** The chain:
+ *
+ *  1. `ChatErrorNotice` renders only when a message carries
+ *     `extraMetadata.chatError.errorType === 'guardrail'` plus a
+ *     `GuardrailPayload`.
+ *  2. The only writer of that metadata is `ChatRuntimeProvider`'s
+ *     `chatErrorExtraMetadata`, fed by a **`chat_error` socket event**.
+ *  3. The only emitter of a `chat_error` carrying a guardrail payload is
+ *     `core/socketio.rs:886`, inside the `socket.on("chat", …)` handler.
+ *  4. The renderer never emits a socket `chat` event. Every turn is sent over
+ *     RPC — `chatService.sendChatMessage` calls `openhuman.channel_web_chat`
+ *     (`chatService.ts:1631`), and that file's own header says so.
+ *  5. On the RPC path `channel_web_chat` does `start_chat(…).await?`
+ *     (`web_chat/ops/channel_ops.rs:212`), so a guardrail rejection propagates
+ *     as an **RPC error** and no socket event is emitted at all.
+ *  6. The RPC error is NOT lossy — it carries the full `GuardrailPayload`
+ *     after a `GUARDRAIL:` sentinel (`start_chat.rs:97`, `:113-115`), verified
+ *     by the first test below. So everything the card needs already reaches the
+ *     renderer; only the parse is missing.
+ *  7. The classifier that would close the gap is unbuilt and says so:
+ *     "`is_guardrail_error_message` / `GUARDRAIL_ERROR_PREFIX` are for a future
+ *     RPC-layer classifier … nothing in-crate consumes them yet"
+ *     (`web_chat/ops.rs:25-27`).
+ *
+ * So this spec asserts the behaviour that exists — a blocked turn is refused at
+ * the RPC boundary and never becomes a turn — and pins the absence of the card
+ * as a KNOWN GAP. When someone wires the future classifier, the second
+ * assertion here fails, which is the intended signal: it means the card can now
+ * render and this spec should be rewritten to assert its contents (verdict tag
+ * plus the guardrail's cited reasons) instead of its absence.
+ *
+ * Writing it the other way round — asserting the card appears — would have
+ * produced a spec that fails today for a reason unrelated to any regression.

+/**
+ * `schedule-card` — the card a `cron_*` tool call renders instead of raw JSON.
+ *
+ * Family: `components/assistant-ui/elements/schedule-card.tsx`, mounted on the
+ * product chat path by `features/conversations/aui/ChatScheduleCard.tsx`, which
+ * `aui/toolkit.tsx` registers for `cron_add` / `cron_update` (as
+ * `CronAddOrUpdateCall`) and `cron_list` (as `CronListCall`). Zero e2e coverage
+ * before this spec.
+ *
+ * The agent really calls the tool here. The mock LLM is scripted to answer with
+ * a `cron_add` tool call; the CORE executes it, creates a real job and returns
+ * a real `CoreCronJob`, and the toolkit routes that result to the card. Nothing
+ * is hand-fed to the component — which is the point, because
+ * `CronAddOrUpdateCall` returns `null` unless `isCoreCronJob(result)` accepts
+ * the shape, so a card on screen is itself evidence that the core's own job
+ * shape reached the renderer intact.
+ *
+ * ⚠️ STATUS 2026-09-24: THIS SPEC DOES NOT PASS YET, and the reason is upstream
+ * of anything it asserts. Observed on a real run against the web lane: the core
+ * answered **`unknown tool cron_add`** and the assistant narrated that as prose
+ * — the transcript rendered `Stopping: the cron_add call` and three
+ * `unknown tool cron_add (` paragraphs as ordinary markdown, so the tool call
+ * was attempted and rejected rather than executed. No schedule card can render
+ * from a call the core refuses.
+ *
+ * That is the observation, and it is reproducible. The CAUSE is not known. A
+ * domain-gating explanation was hypothesised (`cron_*` maps to
+ * `DomainGroup::Automation` at `tools/ops.rs:1273`, and `DomainSet::harness()`
+ * has `automation: false`) and is *consistent* with it, but the runtime default
+ * is `DomainSet::full()` (`core/runtime/builder.rs:486`) where automation is on,
+ * and nothing was found that narrows it for a web-chat turn. Consistent-with is
+ * not caused-by; whoever picks this up should start from what populates the
+ * agent's tool set for a web-chat turn, not from that hypothesis.
+ *
+ * ⛔ UPSTREAM BREAKAGE, established by a CONTROL rather than by inference:
+ * **tool calls do not render in the Playwright web lane on this branch.** The
+ * pre-existing `test/playwright/specs/tool-call-presentation.spec.ts` (tracked,
+ * last touched by `cd3806b19`, authored by nobody in this round) fails at
+ * `expect(page.getByTestId('tool-timeline')).toBeVisible()` — and fails AFTER
+ * its canary assertion passes, so the turn completed and the agent replied
+ * while no tool call rendered.
+ *
+ * That control is sound on its own terms: its `beforeEach` boots the page
+ * BEFORE the test body sets `llmForcedResponses`, so the ordered-queue hazard
+ * (boot-time LLM requests eating queue entries) cannot apply to it, and the
+ * canary rendering proves the scripted sequence was consumed by the intended
+ * turn.
+ *
+ * It went unnoticed because that spec DOES run in ci-full's 64-shard sweep, but
+ * the job carries `continue-on-error: true` and is excluded from the gate
+ * (#3615) — a broken tool-render path fails there invisibly. Which is the
+ * regression class a non-blocking lane is built to hide.
+ *
+ * For THIS spec that is a second, independent blocker: even had `cron_add`
+ * resolved, `CronAddOrUpdateCall` is also a toolkit render on a tool-call part,
+ * so the card could not have rendered. The observed `unknown tool cron_add`
+ * rejection and this render breakage are two separate problems that happen to
+ * produce the same red.
+ *
+ * A second, independent defect in this spec: `getByText(JOB_NAME)` hit a strict
+ * mode violation, resolving to four elements. That needs a narrower locator
+ * regardless of the tool-availability problem above.
+ *
+ * A note on tool names, because the tree currently disagrees with itself:
+ * `tools/impl/meta/collapse.rs`'s header says the scheduler surface "is a
+ * single `cronjob` tool". It is not. `crates/openhuman-core/src/cron/tools/*.rs`
+ * still register `cron_add`, `cron_list`, `cron_update`, `cron_remove`,
+ * `cron_run` and `cron_runs` individually, and `cronjob` appears nowhere but
+ * that comment. The toolkit keys on the individual names, so the card works —
+ * but if the collapse ever lands, `toolkit.tsx` has no `cronjob` entry and this
+ * whole family silently falls back to the raw JSON `ToolDataView`. This spec
+ * would catch that.

+ * `subagent-list` — the fan-out roster a parallel delegation renders.
+ *
+ * Family: `components/assistant-ui/elements/subagent-list.tsx`, mounted on the
+ * product chat path by `features/conversations/aui/ParallelAgentsCard.tsx`,
+ * which `aui/toolkit.tsx` registers for `spawn_parallel_agents`. Zero e2e
+ * coverage before this spec.
+ *
+ * This element is worth an e2e specifically because it is NOT fed by its own
+ * tool result. `ParallelAgentsCard` reads the thread's live tool timeline and
+ * keeps only rows whose `subagent.parentCallId` equals this call's
+ * `toolCallId` (`selectSubagentChildrenByParentCallId`), because parallel
+ * workers arrive as independent `subagent:*` timeline rows rather than inside
+ * the call's own nested transcript. So the card joins two separate streams —
+ * the tool-call part and the per-worker progress events — on an id. A unit test
+ * hands both sides to the component already correlated; only an end-to-end run
+ * can show the core actually stamps `parent_call_id` with the id the renderer
+ * is looking for. If that correlation breaks, `children.length === 0` and the
+ * card returns `null` — the fan-out renders as nothing at all, silently.
+ *
+ * ⚠️ STATUS 2026-09-24: THIS SPEC DOES NOT PASS YET, and the failure is NOT
+ * isolated. Observed: `assistant-ui-parallel-agents-call` never appeared within
+ * 60s. That is all that is known. The page snapshot in the Playwright artifact
+ * was truncated before the transcript, and the artifact directory was later
+ * overwritten by another agent's run (`app/test-results/` is shared, unlocked
+ * state), so there is no evidence of what the transcript contained.
+ *
+ * Three candidate causes, none confirmed here, recorded so the next person does
+ * not re-derive them. The third is the best supported:
+ *
+ * (a) The core-side rejection the sibling schedule-card spec observed for
+ *     `cron_add`, which would mean `spawn_parallel_agents` never ran.
+ * (b) A rendering-side absence: another agent's scripted `memory_store` call
+ *     completed a turn while the DOM held zero tool-call wrappers of any kind.
+ * (c) **Socket events not reaching the browser on this lane.** This card's rows
+ *     come from `state.chatRuntime.toolTimelineByThread`, populated by the
+ *     `subagent_spawned` SOCKET event (`ChatRuntimeProvider.tsx:890-930`, whose
+ *     own comment calls it "this socket ... event"). No events, no children,
+ *     and `ParallelAgentsCard` returns `null` for `children.length === 0` —
+ *     exactly the observed symptom. A third agent measured 11 of 11 failures on
+ *     surfaces fed this way (plan review, elicitation), with the page snapshot
+ *     showing the non-pending branch rendering because
+ *     `pendingPlanReviewByThread` was never populated.
+ *
+ * Two hypotheses were raised and BOTH are now dead, recorded because the
+ * reasoning is the useful part:
+ *
+ * - "Streamed text arrives, so only specific event types fail." The CONCLUSION
+ *   survives, but the evidence originally offered for it did not: it rested on
+ *   settled markdown in the transcript, and a finished assistant message looks
+ *   identical whether it streamed in or was refetched afterwards. The DOM does
+ *   not record how content arrived.
+ * - "No live socket events arrive at all; everything seen was refetched from the
+ *   transcript after the turn." Measured and killed: `chat-thread-isolation`
+ *   passes 3/3, and its case 2 asserts a token visible WHILE the turn is still
+ *   streaming. Live `text_delta` demonstrably arrives on this lane.
+ *
+ * So streaming works. That makes this spec's failure HARDER to explain, not
+ * easier, and rules out the tidy "one cause, four slices" story:
+ * `subagent_spawned` is published by `web_chat/progress_bridge_subagent_events.rs`
+ * (`on_subagent_spawned` -> `publish_seq_stamped`) — the progress bridge, the
+ * same publisher as the streaming that works. It does NOT share a publisher with
+ * `plan_review_request`, which is bridged separately by `ApprovalSurfaceSubscriber`
+ * off the DomainEvent bus (`web_chat/event_bus.rs:41`, `:594-686`). A
+ * plan-review-shaped explanation therefore does not transfer here, and these
+ * should be filed as two findings with a noted resemblance rather than one.
+ *
+ * ⛔ UPSTREAM BREAKAGE, established by a CONTROL rather than by inference:
+ * **tool calls do not render in the Playwright web lane on this branch.** The
+ * pre-existing `test/playwright/specs/tool-call-presentation.spec.ts` (tracked,
+ * last touched by `cd3806b19`, authored by nobody in this round) fails at
+ * `expect(page.getByTestId('tool-timeline')).toBeVisible()` — and fails AFTER

+ * while no tool call rendered.

+ * That control is sound on its own terms: its `beforeEach` boots the page

+ * (#3615) — a broken tool-render path fails there invisibly. Which is the
+ * regression class a non-blocking lane is built to hide.
+ *
+ * Bisect window for that breakage, since the obvious suspects are innocent:
+ * the control was restored by `cd3806b19` at 06:14 on 2026-09-24 and the
+ * breakage was observed the same evening. Two commits on this branch SOUND like
+ * the cause — `71d8874af` "handle missing toolkit in AUI conversation" and
+ * `d5e81a916` "handle missing toolkit state on initial render" — and are not:
+ * their complete diffs add this very `spawn_parallel_agents` toolkit entry and
+ * its import, nothing else. Auto-generated subjects describing a fix that is not
+ * in the diff. `7e1f5d90a` (18:12, desktop shell + chat chrome) touches
+ * `thread.tsx` but its only tool/part change there is a comment. One entry in
+ * the window was NOT examined at all: `58407ea53`, the 15:51 upstream merge.
+ * That is a gap in the search, not a suspicion about the commit — it is
+ * recorded so the next person knows which stone is unturned, and nothing here
+ * should be read as nominating it.
+ *
+ * This supersedes the by-elimination reasoning that preceded it. `ParallelAgentsCard`
+ * is a toolkit render ON a tool-call part, so if no tool call renders this card
+ * cannot render regardless of whether `spawn_parallel_agents` ran, whether its
+ * workers spawned, or whether `subagent_spawned` was delivered. The spec is
+ * blocked upstream of everything it asserts.
+ *
+ * Deciding between them needs one run that captures the transcript. Copy the
+ * artifact out of the tree before releasing the ci-slot: `e2e-web-session.sh`
+ * wipes `test-results/` at start, its wrapper exits 0 even when tests fail, and
+ * the directory is shared with every other agent's run.
+ *
+ * Two workers because the tool's own schema sets `minItems: 2` on `tasks`
+ * (`spawn_parallel_agents_policy_tests.rs:11`); one task is not a valid call.

+ * `elements/context-display` (the composer ring) and `elements/context-breakdown`

+ *
+ * # What "empty state" actually is, and what it is not
+ *
+ * This slice was dispatched on the premise that the empty/missing case is
+ * fragile, evidenced by `fix(aui): handle missing context usage data
+ * gracefully` and `fix(aui): correct context usage display for empty state`
+ * each landing several times. **Those commit messages do not describe their
+ * diffs** — see the report accompanying this branch. Read end to end, the six
+ * commits carrying those two titles changed: a doc comment, two import lines,
+ * a prettier reformat, a layout wrapper `div`, and the removal of a
+ * `if (threadId !== '__never__') return null;` debug line. Not one of them
+ * touched the empty or missing-data branch. They are auto-commits
+ * ("Auto-committed-on: macbook") with generated subjects.
+ *
+ * The empty branch is still worth covering, because it is real code — but it
+ * is worth covering for what it does, which is not what the titles imply:
+ *
+ *   `ContextDisplayRoot` bails with `if (!hasUsage) return null`
+ *   (`context-display.tsx:180`), and `hasUsage` is
+ *   `current.usage !== undefined || totalTokens > 0`. `ContextUsage` builds
+ *   `ringUsage` with `useMemo<TokenUsage>(() => ({ ... }))`, which is **always
+ *   an object**. So `hasUsage` is always true through the product path and the
+ *   bail is unreachable from here: a thread with no turn shows a `0%` ring, it
+ *   does not hide the control.
+ *
+ * That is asserted below as the real empty state. If someone later makes the
+ * ring disappear on an empty thread believing they are fixing this, the first
+ * case fails and points them here.

+ * assistant-ui tool-result presentation elements, end to end.
+ *
+ * Covers three vendored element families that had **zero** e2e coverage before
+ * this file (`git grep -l 'code-diff\|data-table\|artifact-card'` over
+ * `test/playwright/specs` and `test/e2e/specs` returned nothing):
+ *
+ * | Element | Real importer on the product chat path | What makes it appear |
+ * |---|---|---|
+ * | `elements/code-diff.tsx` | `features/conversations/tools/ToolBodies.tsx` `FileBody` | an `edit` tool call carrying `old_string` / `new_string` |
+ * | `elements/data-table.tsx` | `features/conversations/tools/ToolDataView.tsx` | a tool result that is a flat, uniform object array |
+ * | `elements/artifact-card.tsx` | `features/conversations/aui/MediaAndDocumentCalls.tsx` `DocumentArtifactCall` | a `generate_document` / `generate_presentation` call |
+ *
+ * **Not** driven through the dev-only gallery at `/dev/tools`
+ * (`pages/dev/ToolCallGallery.tsx`, "Registered only in dev builds"). That
+ * route imports several of these families and is the easy way to make them
+ * render, but it proves nothing about the product: it mounts the elements with
+ * hand-written props instead of letting a tool result reach them. Every
+ * assertion below goes through a real turn — the mock LLM emits a tool call,
+ * the core runs it, and the chat renders the result.
+ *
+ * Turns go over `openhuman.channel_web_chat` via `helpers/chat-drive.ts`, never
+ * the composer: `ComposerTextBridge` used to take the chat surface to its error
+ * boundary when driven at speed, and a spec about a tool result should not be
+ * able to fail for a composer reason.
+ *
+ * No real backend or third-party calls: the mock LLM is scripted with
+ * `llmKeywordRules`, and the Composio action's payload comes from the mock's own
+ * `composioExecuteResponse_<ACTION>` behaviour knob.
+ *
+ * ## STATUS 2026-09-24: these cases are RED, and not because of what they assert
+ *
+ * Every case here fails at `openToolCall`, before reaching a single element
+ * assertion: the round settles, the agent replies, and no `assistant-ui-tool-call`
+ * card appears. Three independent legs say that is not a claim about this file.
+ *
+ * 1. **A control on a spec this file does not touch.**
+ *    `test/playwright/specs/tool-call-presentation.spec.ts` — restored hours
+ *    earlier in `cd3806b19` — fails at its line 151,
+ *    `expect(page.getByTestId('tool-timeline')).toBeVisible()`, AFTER its canary
+ *    assertion passes. It drives via the COMPOSER (`sendMessage`, lines 108-115:
+ *    `chat-message-input.fill` then `send-message-button.click`), not this file's
+ *    RPC driver, so it exercises the real send path.
+ *
+ * 2. **The `chat-drive.ts` lifecycle bug is NOT the cause.** A peer session found
+ *    that `sendTurn` never dispatched `chatRuntime/beginInferenceTurn`, which a
+ *    real composer send does (`Conversations.tsx:1161`), leaving `isRunning`
+ *    false for RPC-driven turns. That was a genuine harness defect and it is
+ *    fixed (`armTurnLifecycle`). **These four cases were re-run on the fixed
+ *    driver and are still red, with the same message.** Leg 1 was never affected
+ *    by it either, being composer-driven.
+ *
+ * 3. **A second element family, confound removed.** The same peer's `todo` spec
+ *    is still red on the fixed driver with its UPSTREAM stage passing —
+ *    `upstreamBodies()` grew past `before + 1`, so the tool call went out, the
+ *    result came back, and the harness called the model again. Tool round trip
+ *    yes, render no.
+ *
+ * ### Scope: wider than "tool calls do not render"
+ *
+ * That framing is narrower than the evidence. The peer's pinned `todo-checklist`
+ * also failed, and it is not a tool-call part at all — it renders off the
+ * `thread_todos_changed` socket event via `useThreadTodos` (`useThreadTodos.ts:3`;
+ * `TodoListPart.tsx:68` contrasts the two paths explicitly). So **at least two
+ * independent render paths fail: tool-call parts, and a socket-event-driven
+ * pinned surface.** Whether they share a root cause is UNKNOWN and is not
+ * asserted here.
+ *
+ * What CAN be said bounds the search without inventing a cause: the two paths
+ * converge at exactly one place. `ChatRuntimeProvider.tsx` handles both the
+ * tool-call stream (`:806-1050`, `toolCallReceived`) and `thread_todos_changed`
+ * (`:1461`), and they share nothing below it — the tool-call part renders
+ * through the assistant-ui toolkit, the checklist through `useThreadTodos`. So
+ * IF one defect explains both, it is at or above that handler; if it is below,
+ * there are two. That is a constraint on where to look, not a claim about which
+ * is true. (Bound suggested by a peer session, verified here against the
+ * provider source.)
+ *
+ * **These cases are therefore written but UNVERIFIED, and none is revert-proven.**
+ * Proving a fault against an already-red spec establishes nothing, so that was not
+ * attempted. When the lane renders tool calls again, run this file first: if a case
+ * still fails it will fail at its own assertion rather than at `openToolCall`, and
+ * that failure is then about the element.

+/**
+ * `elements/agent-plan.tsx` on the product chat path — the rendered surface of
+ * a parked plan review.
+ *
+ * `chat-plan-review.spec.ts` (#6612) covers the GATE: that the turn really
+ * parks on an in-memory oneshot and that approve / reject / revise each route
+ * the resolution back to the model. It asserts the card exists and says
+ * nothing about what the card shows. This file is the other half: the plan the
+ * user is being asked to approve has to be the plan the agent proposed, and
+ * its progress has to mean something.
+ *
+ * The real importer is `features/conversations/aui/PlanReviewPart.tsx`, which
+ * feeds `AgentPlan` from the live `plan_review_request` payload. There is a
+ * dev-only gallery at `/dev/tools` that mounts `AgentPlan` directly; asserting
+ * through it would prove the element renders an array, which nobody doubts,
+ * and nothing about whether the product ever hands it the right array.
+ *
+ * ## What a real run showed, and what this file therefore asserts
+ *
+ * Written first against `activeIndexFromTodos` (`PlanReviewPart.tsx:29-37`),
+ * which derives `activeIndex` from the thread's live todo list and is strict
+ * about it: same length as the plan, and every item's `content` equal to the
+ * step at the same position. Three cases were written around that.
+ *
+ * **They failed, and the failure is the finding.** Against the built web lane
+ * the plan renders — steps and all — but it renders through
+ * `PlanReviewPart`'s NON-pending branch (`:197-204`, a bare `AgentPlan` at
+ * `activeIndex: steps.length`), not through `PlanReviewCardCore`. The page
+ * showed `Review plan 3 of 3` with the three steps as list items and no
+ * `plan-review-card` anywhere. `pendingPlanReviewByThread[threadId]` was empty,
+ * so the review never parked, so `activeIndex` never came from the todo list
+ * and there was nothing for those three cases to observe. All five cases of
+ * `chat-plan-review.spec.ts` (#6612) failed in the same run for the same
+ * reason — that file had never been executed before this one was written.
+ *
+ * So the todo-progress cases are NOT here. They would have to assert a branch
+ * this lane cannot reach, and a spec that can only fail is no better than one
+ * that can only pass. The parking gap is reported as an issue instead; when it
+ * is fixed, `activeIndexFromTodos` is worth exactly the three cases that were
+ * cut, and this comment is the record of what they were.
+ *
+ * What IS reachable is the element's own job: rendering the steps the agent
+ * proposed, in the order it proposed them, and showing a settled call as
+ * complete. Both are asserted below, and both are on the product path — the
+ * dev-only gallery at `/dev/tools` mounts `AgentPlan` directly, and asserting
+ * there would prove a component renders an array, not that the product ever
+ * hands it the right one.

+/**
+ * The running-status line appears while a turn is in flight and is GONE once
+ * it settles — `elements/agent-status` family, through its real product path.
+ *
+ * Path under test, end to end:
+ *
+ *   `AssistantUiChat.tsx:316`  installs `AgentRunningStatus` as the thread's
+ *                              `RunningStatus` slot component;
+ *   `thread.tsx:844`           `RunningStatusSlot` renders it inside
+ *                              `<AuiIf condition={s => s.thread.isRunning}>`;
+ *   `aui/AgentRunningStatus.tsx:58` with no registered tasks that is a
+ *                              `GenerationLoader` carrying
+ *                              `data-testid="agent-running-status-thinking"`.
+ *
+ * This is deliberately NOT a "the element renders" spec. Every piece above can
+ * pass its own unit test while the composed surface is wrong in the one way
+ * that matters to a user: a status line that never clears. `isRunning` going
+ * stale leaves a permanent "Thinking…" under a finished answer, and nothing
+ * else on the page contradicts it — the answer is there, so the app looks
+ * busy forever with no error to report. A mounted-component test cannot see
+ * that, because it never owns the transition.
+ *
+ * So all three phases are asserted, in order: absent before, present during,
+ * absent after. The before-assertion is what makes the after-assertion mean
+ * something — "still absent" is not evidence of clearing.
+ *
+ * Turns go over `openhuman.channel_web_chat` (`helpers/chat-drive.ts`), never
+ * the composer.
+ *
+ * ---------------------------------------------------------------------------
+ * If you are about to revert-prove this spec, read this first.
+ *
+ * The obvious fault is to drop the `isRunning` gate on `RunningStatusSlot`
+ * (`thread.tsx:848` → `condition={() => true}`). It does turn both tests red,
+ * so it proves the spec is not vacuous — but it proves the WRONG HALF. With
+ * the gate gone the line renders always, including before a turn, so phase 1
+ * ("absent before") fires first and the run never reaches phase 3, the
+ * clears-once-it-settles assertion this spec exists for. A red at phase 1
+ * tells you nothing about whether phase 3 can see anything at all.
+ *
+ * The fault that proves phase 3 is one that leaves phase 1 green: make
+ * `isRunning` STICKY after completion rather than always-true — e.g. have
+ * `chatRuntimeSlice`'s turn-completion path stop deleting the thread's
+ * `inferenceTurnLifecycleByThread` entry — the `delete` sites are
+ * `chatRuntimeSlice.ts:2477`, `:2480`, `:2508` and `:2647`, and a fault needs
+ * whichever one the completing turn actually takes, so check before assuming.
+ * The line is then correctly absent before, correctly present during, and
+ * wrongly present after, which is exactly the shipped regression described
+ * above.
+ *
+ * As of this writing only the first fault has been run. Phase 3 is asserted
+ * but not fault-proven.
+ * ---------------------------------------------------------------------------
+ *
+ * NOT covered here: the `TaskTray` branch of the same component
+ * (`agent-running-status-tasks`, rendered when `s.thread.tasks` is non-empty).
+ * That state is assistant-ui's own, fed only by nested sub-agent transcripts —
+ * `AgentRunningStatus.tsx:13-16` says a plain tool call is not a task by that
+ * definition — so producing it needs a real delegation fixture rather than a
+ * scripted tool call. Written up rather than faked.

+ * second ("...and does not, while a turn streams") a statement about the gate
+ * rather than about a dead gesture. Neither alone would be worth writing.
+ *
+ * Drop is still not covered here. `handlePasteCapture` filters to

+/**
+ * The conversation map rail — assistant-ui's `conversation-map`, on the real
+ * chat path.
+ *
+ * `conversation-map` landed in #6604 with no end-to-end coverage. The unit test
+ * (`features/conversations/aui/ChatConversationMap.test.tsx`) renders it against
+ * a mocked runtime with a fixed four-message fixture, so it proves the element
+ * draws ticks for *that* fixture. Two things it cannot reach: that the rail
+ * groups a real thread into turns rather than counting messages, and that
+ * selecting a tick moves the transcript — `onSelect` scrolls a real viewport and
+ * jsdom has no layout.
+ *
+ * Product path, read rather than assumed:
+ *
+ *   AssistantUiChat                     (features/conversations/components)
+ *     └─ ChatConversationMap            data-testid=chat-conversation-map
+ *          └─ Thread components={{ ConversationMap: ChatConversationMapRail }}
+ *               └─ thread.tsx:426 renders the slot inside the scrolling viewport
+ *                    └─ ConversationMapAui side="right"
+ *                         └─ nav[data-slot="conversation-map"]
+ *                              └─ button[data-slot="conversation-map-tick"] per turn
+ *
+ * Deliberately NOT the dev gallery at `/dev/tools`, which imports the same
+ * element and would prove nothing about the product.
+ *
+ * # Why this seeds thread messages instead of running agent turns
+ *
+ * `conversation-map` is a presentation component over `state.thread.messages`.
+ * Producing those messages by running real turns made the spec depend on turn
+ * lifecycle rather than on the rail, and every settle signal available was
+ * either vacuous or measured the wrong thing. Measured across several runs, not
+ * assumed:
+ *
+ *  - `stop-generation-button` belongs to the composer, and a turn driven over
+ *    `channel_web_chat` need not put the composer into its generating state, so
+ *    `toBeHidden` on it passes instantly.
+ *  - A reply's FIRST streamed chunk renders ~20ms into the stream, so the next
+ *    turn goes out mid-turn. The default `queue_mode` is `interrupt` and the
+ *    superseded turn is discarded: after two turns the store held
+ *    `messages=2[user,agent]` and the rail correctly drew ONE tick.
+ *  - A reply's LAST chunk renders before the turn's terminal event, so the same
+ *    supersede happens in a narrower window.
+ *  - `queue_mode: 'followup'` did not accumulate either.
+ *
+ * `threads_message_append` is the RPC the renderer itself posts
+ * (`services/api/threadApi.ts:85`), and `loadThreadMessages` is the documented
+ * rehydration path, so seeding this way fills the same store the live path
+ * fills — without making a rail test a turn-lifecycle test. No mock LLM is
+ * scripted here because none is needed.

+ *          └─ ConversationSearch        data-testid=chat-conversation-search
+ *
+ * The unit test (`ChatConversationMap.test.tsx`) opens the bar with Ctrl+F and
+ * checks the counter reads `1/2` for a two-message fixture. What it cannot
+ * reach is the cycle this spec covers — a real thread, a hit count that tracks
+ * what was actually said, stepping between matches, and the bar returning to
+ * its empty state when the query is cleared. `buildHits` also reads message
+ * geometry out of the live viewport for each hit's `position`, which jsdom
+ * cannot produce.
+ *
+ * # The needle appears only in prompts, on purpose
+ *
+ * `buildHits` searches every message in `thread.messages`, user and assistant
+ * alike. If the scripted reply could contain the needle the expected count
+ * would depend on the mock's output as well as the prompts, and a wrong count
+ * would be ambiguous between the two. The replies here are fixed text with no
+ * overlap, so the expected hit count is exactly the number of prompts sent.
+ *
+ * # What this does NOT assert, and why
+ *
+ * The brief for this work described search as narrowing the conversation-map
+ * entries and restoring them when cleared. It does not, and the test says so
+ * rather than asserting a behaviour that is not implemented:
+ * `ConversationMapAui` takes only `side` and `className`
+ * (`conversation-map.aui.tsx:126-132`) and reads `state.thread.messages`
+ * directly — the query lives in `ChatConversationMap`'s own state and never
+ * reaches it. What narrows is the hit set the search bar owns. The final
+ * assertion below pins the rail as *unchanged* across the search, so if the
+ * two are ever wired together this spec fails and is updated deliberately
+ * instead of silently continuing to describe the old behaviour.

+/**
+ * Durable agent reply — losing the stream costs a repaint, not the answer.
+ *
+ * Matrix 4.2.10 states the contract: `deliver_response` persists an unsegmented
+ * reply under `agent:<request_id>` BEFORE publishing the terminal event, so a
+ * dropped socket, a failed `threads_message_append` or a reloaded webview costs
+ * a repaint rather than the answer, and the client's own append collapses onto
+ * that row by id. Its note says what is missing: *"WD E2E (kill the append
+ * mid-turn) is a follow-up"*.
+ *
+ * The existing layers cover the two ends. RU
+ * (`web_chat/reply_persistence_tests.rs`) proves the core writes the row, its
+ * idempotency and the empty/missing-thread paths. VU
+ * (`providers/__tests__/ChatRuntimeProvider.test.tsx`) proves the mirrored id
+ * and the refetch — against a mocked client. Neither runs the round trip
+ * through a real transport, and this is a data-loss contract: when it breaks,
+ * a finished answer disappears, or appears twice. Nothing errors either way.
+ *
+ * Two instruments, deliberately different:
+ *
+ *   1. A reload mid-stream. Cheap, needs no fault injection, and is the exact
+ *      "reloaded webview" the contract names.
+ *   2. Failing one real `threads_message_append` over the wire. The renderer
+ *      posts that RPC itself (`src/services/api/threadApi.ts:85`) to the core
+ *      URL seeded into localStorage, so Playwright can fail exactly one call
+ *      and let the rest through. There is no fault-injection hook on the core
+ *      side and none is needed.
+ *
+ * "Exactly once" is the assertion in both cases, not "present". A broken
+ * collapse-by-id shows up as two copies of the answer, which no "is it there"
+ * check would catch.

+ * *"WD E2E (agent-driven park flow) tracked as follow-up"*. The three existing
+ * layers each own one end of the mechanism and none of them owns the join:
+ *
+ *   RU  `agent/plan_review/gate.rs`   — the oneshot parks, resolves, TTL-rejects.
+ *   RI  `tests/json_rpc_e2e.rs`       — `plan_review_decide` answers.
+ *   VU  `aui/PlanReviewPart.test.tsx` — the card renders and calls the RPC.
+ *
+ * What nothing covers is a REAL turn held open on an in-memory oneshot
+ * (`PlanReviewGate`, one per process, not a database row) while a browser paints
+ * a card from a socket event, and released when that card's button resolves it.
+ * Every one of those pieces can pass its own test while the turn stays parked
+ * forever — and a parked turn is silent. No error, no log line saying why; the
+ * user watches a spinner that never ends.
+ *
+ * Turns are driven over `openhuman.channel_web_chat` (see `helpers/chat-drive.ts`),
+ * never by typing, so a composer change cannot be reported as a gate failure.
+ *
+ * The agent is scripted through the mock's keyword rules. Stage 1 matches the
+ * prompt and answers with a `request_plan_review` tool call; stage 2 matches the
+ * tool's own result string, which the core fixes verbatim
+ * (`agent/plan_review/tool.rs`: "approved: the user approved the plan…",
+ * "rejected: the user rejected the plan…", "revise: the user requested changes…").
+ * That is what makes the approve/reject assertions real rather than cosmetic:

+/**
+ * The `todo` tool's whole-list write, as it reaches the DOM — `elements/todo-list`
+ * family, through both of its real product paths.
+ *
+ * There are two renders of the same vendored element and they are not the same
+ * claim:
+ *
+ *   PINNED   `Conversations.tsx:1658` — `data-testid="todo-checklist"`, fed by
+ *            `useThreadTodos` off the live `thread_todos_changed` event. One
+ *            per thread, always current.
+ *   SNAPSHOT `aui/TodoListPart.tsx:76` — one per `todo` tool call in the
+ *            transcript, fed by that call's own `args`/`result`
+ *            (`TodoListPart.tsx:62-66` is explicit that these are different
+ *            sources).
+ *
+ * `app/test/e2e/specs/chat-todos-goals.spec.ts` (WDIO) owns the pinned list's
+ * content across turns, so this spec does not re-assert that. What nothing
+ * covers is (a) the transcript snapshots existing at all, (b) an earlier
+ * snapshot staying frozen when a later write lands — the property that
+ * separates a per-call snapshot from a shared live store — and (c) the
+ * single-`in_progress` invariant surviving to the DOM.
+ *
+ * On (c): the core rejects a list with two `in_progress` items
+ * (`crates/openhuman-core/src/agent/tools/todo_tests.rs:77`,
+ * `two_in_progress_items_are_rejected`). That is enforced server-side and
+ * covered there. What is NOT covered anywhere is what the browser shows when
+ * the rejection happens, and the pinned list is the surface that must not lie:
+ * it is the user's view of stored state, so it may never show two active
+ * items for a write the core refused to store.
+ *
+ * Status vocabularies differ between the two ends and the mapping is the
+ * adapter's job (`TodoListPart.tsx:20-31`): the core writes
+ * `pending|in_progress|completed`; the element renders
+ * `pending|active|done|failed` and exposes each item's state as a screen-reader
+ * span (`todo-list.tsx:82`). Those spans are what this spec reads — real
+ * accessibility-tree output, not a test-only attribute.
+ *
+ * Turns go over `openhuman.channel_web_chat` (`helpers/chat-drive.ts`), never
+ * the composer.

+//! RAM-driven local-model tier selection, asserted from OpenHuman's own seam.
+//!
+//! # Why these live here and not upstream
+//!
+//! The thresholds these tests pin (`MIN_RAM_GB_FOR_LOCAL_AI`, the `recommend_tier`
+//! bands) belong to `tinyinference_local::presets`, which has its own unit tests
+//! in `presets_test.rs` / `presets_device_test.rs`. **No OpenHuman lane runs
+//! them.** `vendor` is listed in the root `[workspace] exclude`, both Rust lanes
+//! invoke `cargo test --manifest-path Cargo.toml --workspace` or a named
+//! `--test <target>`, and no CI step names `tinyinference-local`. The crate sits
+//! two submodule hops down, under `vendor/tinyagents/vendor/tinyinference/`.
+//!
+//! OpenHuman *consumes* those thresholds — `inference_apply_preset` and
+//! `inference_presets` are built on `apply_preset_to_config` and
+//! `current_tier_from_config` in this module, and `inference/ops.rs` calls
+//! `detect_device_profile` and `presets::recommend_tier` directly. So an
+//! upstream change to a band silently changes what OpenHuman recommends, and
+//! nothing that runs would notice.
+//!
+//! These are therefore **consumer contract tests**: they assert the behaviour
+//! OpenHuman depends on, at the version OpenHuman has pinned. They are not a
+//! second copy of the upstream suite — they cover only the values this repo's
+//! own RPC surface hands to users.
+//!
+//! # What is NOT covered here, and cannot be
+//!
+//! `inference_device_profile` reports the *real host's* RAM, so the RPC layer
+//! can only assert `total_ram_bytes > 0` (which `tests/json_rpc_e2e.rs` already
+//! does). OpenHuman exposes no seam that injects a synthetic device profile, so
+//! the threshold behaviour is reachable only by constructing a `DeviceProfile`
+//! in-process, as below. An end-to-end "this 4 GB machine defaulted to cloud"
+//! assertion would need that injection seam and is not written.

+// The function's comment states the invariant from the failure side:
+//
+//     Surface real storage failures instead of masking them as an empty
+//     first-run doc. The distinction still holds through the family: a driver
+//     with no goals yet answers an empty `GoalsDoc` rather than `NotFound`, so

+//
+// That sentence has two halves. This test pins the half that is reachable
+// without a fault-injection seam: **an empty store must not be reported as a
+// load failure**. If `read_goals` ever started mapping "no goals yet" onto
+// `Err`, enrichment would refuse to run for exactly the users it exists to
+// help — everyone who has not set a goal yet — and the two prompt tests above
+// would stay green, because they never call `read_goals` at all.

+// The other half (a REAL backend failure must propagate rather than becoming a
+// first run) is deliberately NOT asserted here. Reaching it needs a goals
+// driver that errors on demand, and no such seam exists in this module today;

The PW case now pins the contract — what the core holds in `default_model` is what the routing page shows, before and after a reload, with no write-back on render.

+//! Default messaging channel: `channels_set_default` / `channels_get_default`.
+//!
+//! # Why this target exists
+//!
+//! Both methods are in the domain-e2e gate's uncovered list
+//! (`scripts/check-domain-e2e-coverage.mjs`), which counts only
+//! `tests/**/*_e2e.rs` targets. Before this file the complete picture was:
+//!
+//! * `app/src/services/api/channelConnectionsApi.ts:255`, `:263` — **shipped
+//!   frontend code** calls both.
+//! * `app/src/services/api/channelConnectionsApi.test.ts:47-60` — a Vitest that
+//!   asserts the client *emits the right method name* against a mocked
+//!   transport. It never reaches the core, so it would keep passing if both
+//!   controllers were deleted tomorrow.
+//! * Four WDIO/Playwright specs call `channels_set_default` as **setup** and
+//!   assert nothing about it.
+//!
+//! So the round trip had no coverage anywhere above a mocked transport.
+//!
+//! # What is actually worth asserting
+//!
+//! A bare set→get round trip is the weak half. `channels/proactive.rs:100-116`
+//! documents the interesting invariant: `channels_set_default` mutates the live
+//! proactive subscriber's `active_channel` handle **in place** via
+//! `set_runtime_active_channel`, "so a default-channel switch from the UI takes
+//! effect without a restart" (issue #3712, "switch default channel
+//! Telegram<->Discord"), and `proactive.rs:226-240` reads that handle back on
+//! every proactive delivery. The failure that bug describes is: config
+//! persists, the live handle does not update, proactive messages keep going to
+//! the old channel until the process restarts — and a test that only reads the
+//! config back cannot see it.
+//!
+//! **That assertion IS made here** — see
+//! `set_default_applies_to_the_live_proactive_handle`. An earlier revision of
+//! this file omitted it, on the reasoning that `proactive.rs:135-138` says
+//! `set_runtime_active_channel` is "a no-op when no subscriber has registered a
+//! handle (e.g. unit tests)", so the assertion would pass vacuously. **That was
+//! wrong**: `register_active_channel_handle` (`proactive.rs:129`) is `pub`, so
+//! the test registers its own handle and no channel runtime is needed. The
+//! non-vacuity control is asserting the handle reads `None` *before* the call —
+//! without it, "still unset afterwards" would look like a pass.
+//!
+//! So this target asserts everything reachable from the RPC surface — the round
+//! trip across the wire, persistence, canonicalisation, the documented `"web"`
+//! fallback — plus the live-apply half that is the actual #3712 regression.
+//!
+//! No network: `api_url` points at a closed port.
+//!
+//! Run with: `cargo test -p openhuman-cli --test channels_default_channel_e2e`

+/// `channels.set_default` and `channels.get_default` differ in WIRE SHAPE.
+///
+/// Nothing else pins this, and the difference is invisible to every helper that
+/// unwraps tolerantly. `set_default_channel` returns `RpcOutcome::single_log(...)`
+/// (`channels/controllers/ops/connect/status.rs:101-104`), so its payload arrives
+/// ENVELOPED as `{ result, logs }`. `get_default_channel` returns
+/// `RpcOutcome::new(_, vec![])` (`:115`), so its payload arrives BARE. Adding or
+/// removing a single log line in either handler silently changes what every
+/// caller must parse — the §6 log-envelope rule, on a live pair of methods.
+///
+/// The reason this needs its own case: the tolerant `payload()` helper here, and
+/// the equivalent in `tests/channels_default_channel_e2e.rs`, both unwrap an
+/// inner `result` when present and fall through when not. That is the right
+/// behaviour for a caller and it is exactly what makes the flip undetectable —
+/// every other test in both suites would keep passing if either handler's
+/// envelope inverted. So this case reads the RAW JSON-RPC result rather than the
+/// unwrapped payload.
+///
+/// **Scope:** wire shape only. `tests/channels_default_channel_e2e.rs` owns the
+/// round trip, on-disk persistence, canonicalisation, the `"web"` fallback, and
+/// — since the split agreed with its author — the live-apply assertion

+//!
+//! * `memory::ops::kv_graph_tests::graph_handlers_roundtrip_relation_rows` is a
+//!   unit test that upserts a relation and queries it back through a real
+//!   module-backed provider. It calls the `ops` functions **directly**, so it
+//!   proves the handler wiring but never touches JSON-RPC dispatch or the
+//!   `serde` layer that builds `GraphUpsertParams` / `GraphQueryParams` from a
+//!   wire payload.
+//! * `tests/worker_c_modules_e2e.rs` names `openhuman.memory_graph_upsert` and
+//!   `openhuman.memory_graph_query` in a 68-method loop that calls each with
+//!   `json!({})` and asserts `assert_rpc_completed`. That helper tolerates an
+//!   error response as long as it is not `unknown method:`, which is the
+//!   strongest thing a probe with no arguments can honestly claim. It is a
+//!   registration check and cannot observe a graph that writes and never reads
+//!   back.
+//!
+//! So what has no coverage at all, and is what this file asserts:
+//!
+//! 1. The **wire path** — that a relation posted as JSON to `/rpc` survives
+//!    deserialisation, dispatch, the guard, the module and serialisation back
+//!    out. Both params structs take `namespace` as `#[serde(default)] Option`,
+//!    so a wire payload takes a different path through serde than a
+//!    hand-built struct literal does.
+//! 2. **Namespace isolation** — that a relation stored under one namespace is
+//!    not returned when querying another.
+//!
+//! On (2): the deleted test asserted `all_rows.len() >= graph_rows.len()`, i.e.
+//! that an unfiltered query is a superset of a namespace-scoped one. That
+//! assertion is **weak on its own** — a driver that ignored the namespace filter
+//! entirely would return everything for both queries and still satisfy it. This
+//! file keeps the superset check because it pins the documented relationship,
+//! and adds the isolation check that actually fails when the filter breaks.
+//!
+//! Deliberately NOT covered here: `memory_tree_graph_export`. Despite the name
+//! it exports the summary-tree / contacts graph
+//! (`memory::read_rpc::graph::graph_export_rpc`), not the relation triples
+//! `graph_upsert` writes. It needs its own case.
+//!
+//! No network: the config points `api_url` at a closed port and disables
+//! embeddings, and every assertion is local.
+//!
+//! # Running it
+//!
+//! ```text
+//! cargo test -p openhuman-cli --features modules --test memory_graph_roundtrip_e2e
+//! ```
+//!
+//! **`--features modules` is required.** `openhuman-cli`'s `modules` feature is
+//! NOT in its `default` set (`crates/openhuman-cli/Cargo.toml:415`, `:423`), and
+//! without it `modules::memory::set_modules_policy` is `#[cfg]`-compiled away —
+//! so `ensure_memory_seams` becomes a silent no-op and every graph call answers
+//! "the module host policy was never published". The memory driver is
+//! module-backed, so there is no non-module path to assert against. The same
+//! applies to the sibling `tests/memory_roundtrip_e2e.rs`, which does not say
+//! so and fails 6/6 locally without the flag; that is environmental, not a
+//! defect in either file. CI's `rust-e2e` lane supplies both the feature and a
+//! built `TINYMEMORY_TEST_MODULE`.
+//!
+//! A large stack is also needed — `RUST_MIN_STACK=67108864` — because
+//! publishing the policy touches deeply nested config types.

+//! E2E coverage for the `tree_summarizer` ingestion buffer.
+//!
+//! Gate controller `tree_summarizer_ingest` had zero references under `tests/`
+//! or `app/test/` before this target.
+//!
+//! The claim under test is a **boundary contract**, which is why this is an RI
+//! suite rather than a unit test. `memory/tree/tree_runtime/ops.rs` defaults the
+//! timestamp host-side, deliberately, and says why:
+//!
+//!     // Defaulted here rather than driver-side, exactly as before: the reply
+//!     // echoes the instant the content was filed under, and a timestamp the
+//!     // driver resolved would disagree with the one reported here by however
+//!     // long the call took to cross.
+//!
+//! If that defaulting ever migrates across the bus, the reply starts reporting
+//! a different instant than the one the content was actually filed under. The
+//! field stays present and stays plausible, so every downstream ordering or
+//! dedupe decision keyed on that echo drifts silently. Nothing catches it
+//! today.
+//!
+//! Run with: `cargo test -p openhuman-cli --test tree_summarizer_e2e`
