…not the rpc wire Replaces the observer wire waits that only synchronized on a write with bounded settles on the persisted row the assertion already reads: untilPanelDraft (drafts.get) and untilNavigationHref (navigation.get), both with explicit hangGuardMs/intervalMs bounds. Hold-coupled navigation waits (embed.it 96/123/128) and rebind's transport-order-sensitive wait keep riding the observer. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…past a baseline cursor recording-attachment and lazy-capture now read ext.recorder.window's cursor before the action and assert on the events ext.recorder.events appends past it: two click interactions for the widget flow, a full snapshot for the recording_start flow. No total-count predicate can satisfy either. lazy-capture's startedCount flush assertions keep riding the observer. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…route taps Consolidates every normal-boot page-plane subscription wait onto awaitPagePlaneSubscribed in extension-testkit, and replaces the two hand-rolled page.route taps in embed e2e with the gateRpcCalls helper. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ic observer await Split the raw rpc-observer affordance into modules that each own one legitimate reason to touch the wire, and re-home every consumer onto the surface that states its reason. - rpc-counts: rpcCallCursor/rpcCallMark/httpRpcRequestUrls. Nothing in the module returns a promise, so it cannot express a settle. Counts are cursor-relative, which removes the all-time-count footgun. - rpc-wire: watchRpcWire(page) with nextChatSend, chatReconnect, sessionsBootTraffic and the two sessions cursors. Fixed paths, and each method returns the asserted content instead of a call record. - navigation-wire: relocates the hold machinery and the navigation write waits out of embed test helpers; the kit-state reads stay in embed. - rpc-fault: faults now expose answered(), bound to their own path and expected status, so apps/conciv waits on the fault it installed rather than on a path it names. The watchers must be created before the traffic they observe, which the object shape now makes structural rather than a forgettable prerequisite. Refs #339 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…extension-testkit Moves the observer's own Playwright suite, plus the rpc-fault and navigation-hold suites that share its ws-probe harness, into @conciv/extension-testkit and deletes the "./rpc-observer" entry from its exports map. The probe fixture, its vite build, the probe server and the probe suite move with them; the generic http helpers (listenLocal, serveHost) and the persisted-navigation readers move into the package and embed imports them back, so the legal embed -> extension-testkit direction is preserved and no helper is duplicated. Also collapses the host-page-with-handle preamble shared by remount and rebind into openHostWithHandle, which fallow flagged as introduced duplication once the observer call was removed from rebind.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Retain the session gates and assert that no session RPC was captured.
gateRpcCalls only queues matching requests. It does not fail the test.
stallSessionRpcs discards both RpcGate values. An unexpected sessions/list or sessions/resolve request can therefore be held while the launcher still renders, and this test can pass.
Return the gates. After the launcher reaches its stable UI signal, assert that both gates have pending() === 0. Dispose the gates during cleanup.

…ectly, leak-proof probe teardown, escaped href fragments CodeRabbit review on PR #514: - warm-session-resolve retains the rpc gate handles and asserts sessions.resolve captured nothing at click time, instead of only inferring it from the composer appearing; gates are disposed in a finally so a failure leaves no routes installed. sessions.list legitimately refires when the panel mounts its session queries, so only resolve is asserted at zero. - probe-suite closes the host inside try/finally so kit.cleanup always runs, and no longer swallows a cleanup failure behind console.error. - nextWriteCarrying escapes the caller-supplied href fragment before building the RegExp, so a fragment carrying regex metacharacters cannot throw or overmatch.

#513 replaced DraftRow.grabs with attachments, so the checkpoint-1 B4 assertion is re-expressed against the persisted grab attachment: decode the GRAB_MIME attachment's base64 data, parse it with parseGrabPayload, and assert the grabbed element's own text through a server-state read. Upstream's new drafts.set call site in chat-pane is re-homed onto a server-state poll instead of the deleted generic awaitRpcCall. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Test suites addressed widget routes as raw strings, so renaming or
deleting a route left the tests compiling against a route that no
longer exists. seedRoute now validates {to, params, search} against
the registered conciv router through linkOptions, and builds the href
with the router's own interpolatePath/defaultStringifySearch instead
of string concatenation. seedRawHref keeps the deliberately-invalid
route in embed.it expressible. panelSessionId inverts the router-built
panel href instead of index-juggling the URL.

…ckdoor Boot a fresh core kit per test in the proxied embed suite, embed.it, create-conciv, rebind and transport-selection so isolation comes from a fresh database rather than a navigation reset. Delete seedRoute/seedRawHref/routeHref/untilNavigationHref, the extension-testkit navigation-wire tap and its own test, and the two browser-level navigation hold tests whose stamp-arbitration invariant is already covered directly by packages/core/test/rpc/wire.it.test.ts. The composer suites now reach the panel by clicking the launcher instead of seeding a panel route. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…session selector The panel route guard is reachable through a real user path: sessions.list surfaces a harness-history session conciv has never adopted under its RAW harness id, and picking it in the session selector navigates the app to /panel/<rawHarnessId>. The test opens the panel from the launcher, picks that session, and asserts the persisted route landed on the canonical conciv session id the server minted for it.

packages/embed/tests/e2e/session-canonicalize.it.test.ts:36
- This replacement no longer exercises boot-time canonicalization of a persisted
/panel/<raw harness id>route. Starting from a blank page and selecting the option uses the normal session-selection path, so a regression limited to restoring raw routes would now pass. Seed the raw route before navigation and assert that boot rewrites it to the adopted conciv session.

Half right, and the half that is right is my fault — the PR description was stale, not the code. I have rewritten it.
What you correctly spotted: the description still claimed navigation-wire was a retained surface and that the navigation-hold suite had moved into extension-testkit. Both were true three commits ago. 5a0629b0 deleted them and I did not update the body.
Where the conclusion does not follow: the deletion was deliberate, not an oversight, and it does not drop coverage.
Those tests froze clocks in two browser tabs, intercepted a websocket frame, decoded RPC frames to find a navigation call, parked it, queued the rest, and released in order — all to control an arrival order that the rule under test never reads. The invariant is one SQL clause in packages/core/src/api/rpc/router.ts:137-149:
.onConflictDoUpdate({target: navigation.id, set: row, setWhere: lt(navigation.updatedAt, input.updatedAt)})Overwrite only if the stored stamp is older than the incoming one. It is arbitrated per request on the stamp value; two writes in either order produce the same result.
packages/core/test/rpc/wire.it.test.ts:212-249 already tests exactly that, directly against the server — stale rejected, equal-stamp rejected, clock-skew guard covered — and it predates this PR. That is stricter than the browser tests, which only inferred the outcome from a final href. So restoring the module would re-add a wire tap to re-test a database clause that already has better coverage.
navigation-hold.it.test.ts is a separate case: its four tests only ever verified that the tap itself worked. Once the tap is gone they assert nothing about the product.
The wider change is that tests no longer write app state to set themselves up at all — navigation seeding was a backdoor, and all router interaction now goes through the UI. Removing the hold machinery is part of that, not collateral from it.

- This returns the first panel route anywhere in the history rather than the active entry at
persisted.index. After switching sessions, draft waits can therefore inspect an older session and either pass on stale data or time out despite the current draft being persisted. Parse onlypersisted?.entries[persisted.index]?.href, matchingcurrentHref's navigation semantics.
return entries.map((entry) => panelSessionIdOf(entry.href)).find((sessionId) => sessionId !== '') ?? ''
packages/extension-testkit/src/rpc-wire.ts:17
chat.senddoes not guarantee a stringcontent: the contract also accepts attachment-part arrays and the legacytextfield. This genericnextChatSend()helper will therefore throw after observing a valid send (for example, any message with an attachment). Either model the full contract input in the returned frame or narrow the helper's name/API explicitly to string-content sends.

…ick race (#521) * fix(site): #502 try-it-live primary CTA + pre-mount click race Promotes TryLiveButton to the hero's sole primary CTA and closes the pre-mount click race root-caused during this PR: embed's mount() promise was resolving before the widget's root route onMount had registered its conciv:open-panel listener, so an early click (or a dismissed visitor's only path back in) was silently dropped even after switching mount-live-widget.ts off the fire-and-forget mountConciv() call. packages/embed/src/mount-impl.tsx now threads an interactive signal through apps/conciv's router context, resolved from __root.tsx's onMount once the listener is live, and mount() does not resolve until that fires. Adds a mobile explanatory line in place of the previous empty gap. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(site,embed,protocol): port TanStack Devtools event-bus protocol to close the click-race class Fixes the three review findings on the try-it-live race fix (stale React snapshot in open(), embed-internals leak in mount-live-widget.ts, unhandled mount-failure leaving the button stuck), then ports the queue-until-connected handshake protocol from TanStack Devtools' event-bus-client (packages/protocol/src/event-bus.ts) so the whole class of "sender fires before receiver is listening" races is closed structurally rather than patched per-event. - createEventBusClient/createEventBusHost: sender queues emits until the receiver acks a connect handshake (bounded retries, then an explicit failed state that drops the queue). - apps/conciv's root route is now the panel-commands host, acking once its open/close/toggle listeners are live (the same point that already resolved mount()'s promise). - embed's createConciv().open()/close()/toggle() and the site's TryLiveButton both emit through bus clients on that channel instead of bare window.dispatchEvent; TryLiveButton's hand-rolled pendingOpen/widget-mounted machinery is gone, replaced by the bus client's own state. - Wire event names are unchanged, so existing raw dispatchers (the iOS bridge, embed's own IT/unit tests) keep working exactly as before — the bus is additive reliability for callers that opt in. - mountConciv() now returns the mount() promise instead of void. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(protocol): event bus emit-after-failure restarts handshake; simplify scheduler emit() called while the client is in 'failed' state now resets retryCount and restarts the handshake instead of silently dropping the event, so a client that exhausted its retry budget can recover on new user intent without a page reload. Also drops the Map+counter wrapper in defaultScheduler: setInterval's own return value is already an opaque handle, so it's passed straight through to clearInterval. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(embed): dispose bus client on unmount, guard panel command import failure, clean up script root on mount failure Prevents a pre-unmount panel command from leaving the bus client's retry interval running forever, stops a rejected dynamic import from poisoning every later open/close/toggle call, and removes the mounted script-root marker if mount() rejects so mountConciv() can retry instead of early-returning forever. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(embed,plugin,extension-compiler): resolve interactive on dispose; guard fire-and-forget mountConciv call sites; fix test scheduler accounting Teardown between boot() resolving and the widget's onMount left the interactive promise pending forever, hanging mount(). Disposal now resolves it. The extension-compiler bootstrap template and the Next.js widget shim both fire-and-forgot mountConciv, which now rejects on startup failure; both call sites catch and log. The manual test scheduler's interval accounting subtracted cumulative clears from live size, going negative after a genuine clear. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(protocol): faithful port of the TanStack Devtools in-page event bus Rewrites the panel-command event bus as an envelope protocol mirroring TanStack Devtools' EventClient/ClientEventBus: - every emit wraps as {type: '<pluginId>:<suffix>', payload, pluginId} and rides one fixed bus event, conciv-dispatch-event - fixed global handshake: conciv-connect / conciv-connect-success - createEventBus(start/stop) re-dispatches each envelope as both the specific <pluginId>:<suffix> event and a global conciv-global event, and answers the connect handshake - client on()/onAll() replace the old host-side on(); onAll filters by pluginId; both return unsubscribers - queue-until-connected, bounded retry, ack flushes in order Panel commands move to pluginId 'panel' with open/close/toggle suffixes, so the wire events are panel:open/panel:close/panel:toggle. The widget root, embed handle, landing button and iOS bridge all speak the bus through a client. Status events stay raw window events.

What
Two connected changes to how the test suites synchronize and how they address routes.
1.
rpc-observeris no longer reachable outside its own package. It exposedcompleted(filter)/firstEvent(filter)— generic awaits parameterized by a path. One primitive answered both "assert this exact frame crossed the wire" (legitimate) and "wait until things settled" (the misuse #339 exists to delete), with nothing distinguishing them at the call site. Waits that were really about server state now read server state; the raw observer became module-private.2. Tests no longer write app state to set themselves up. Navigation seeding was a backdoor: tests wrote the navigation row directly instead of driving the app. That is gone — all router interaction goes through the UI.
What enforces it
The exports map.
"./rpc-observer"is gone from@conciv/extension-testkit, so Node and TypeScript both refuse to resolve it — a whole-repopnpm typecheckfails on any attempt to import it. 16 external importers went to zero. Not a convention, not a lint rule.What replaced it, each named for the protocol fact it asserts:
rpc-countsrpcCallCursor/rpcCallMark/httpRpcRequestUrls— contains no promise at all, so it is structurally incapable of being awaited as a settle. Counts are cursor-relative, killing the all-time-count footgun.rpc-wirenextChatSend,chatReconnect,sessionsBootTraffic,sessionsResolvedSince,sessionsListedSince. Every path is baked in — none takes an arbitrary path.rpc-faultanswered()bound to a fault's own path and expected status.page-planeawaitPagePlaneSubscribed— one helper for subscription liveness, replacing four hand-rolled copies.Adding a new wire assertion now means naming a new helper. A wait that cannot be named is exactly the wait that should have been a server-state read.
Test isolation and the removed backdoor
Every suite now boots its own kit per test, so isolation is a fresh database rather than a cleanup step. That deleted 9
beforeEachnavigation resets outright with nothing replacing them. Cost: +8% on the embed suite (2.6m → 2.8m).Also deleted:
navigation-wire.tsand its export,navigation-hold.it.test.ts, and the twoembed.itin-flight ordering tests.Those tests froze clocks in two browser tabs, intercepted a websocket frame, decoded RPC frames to identify a navigation call, parked it, queued the rest, and released in order — to control an arrival order the rule never reads. The invariant is one SQL clause (
packages/core/src/api/rpc/router.ts:137-149):Overwrite only if the stored stamp is older.
packages/core/test/rpc/wire.it.test.ts:212-249already tests it directly — stale rejected, equal-stamp rejected, clock-skew guard — more thoroughly than the browser tests did, and it predates this PR. The hold machinery was an elaborate way to reach a rule a four-line RPC test already pins down, andnavigation-hold.it.test.tsonly ever verified the tap itself.Two tests that used the backdoor as a shortcut into the panel now click the launcher like a user. Canonicalization of a raw harness session route is now driven through the UI: harness-history sessions surface under their raw id, so the test opens the panel, picks that session in the combobox, and the app's own
beforeLoadguard canonicalizes it.Evidence
Every migration shipped with a named discrimination mutation: break the underlying behavior in product source, run it, capture the replacement going red, revert. A replacement that stayed green under its mutation was rejected. The sharpest:
flush-drops-clicksleft the recorder liveness barrier green while the click-content predicate went red — proving a total-count predicate would have survived, which is why recorder predicates assert appended-event content past a baseline cursor.Also swept for vacuous predicates — any wait whose match set includes the empty/initial state (
!href.includes(...)matches''). Found one real hole and fixed it with a positive barrier.Gates
Full serial embed suite, extension-testkit (vitest + playwright), recorder, tanstack, apps/conciv, whiteboard — all green. Whole-repo typecheck 96/96, lint 101/101, format clean.
fallow audit0 introduced. 3x serial green on every touched file.Acceptance greps, both clean:
from '@conciv/extension-testkit/rpc-observer'→ zero hits repo-wide.page.route/routeWebSocketin test code → only insidepackages/extension-testkit.Notes for review
no-changesetlabel applied. The only published package touched is@conciv/embed, and only itstestscript and two devDependencies — neither is installed or run by consumers. Everything else is test code or the private@conciv/extension-testkit.extension-testkitdeliberately gained no dependency on@conciv/embed; the widget-bundle readers stayed behind and only generic HTTP helpers travelled, in the already-legalembed -> extension-testkitdirection. The reverse would have been a circular package dep.completeConnectHandshakekeeps its own fresh-observer wait rather than adoptingawaitPagePlaneSubscribed— sharing the cached observer would let a stale earlierpage/queriessatisfy it instantly.apps/conciv/test/chat-pane.browser.test.tsxis touched only because merging feat: #487 grabs are attachments — snapshot survives reload, cards in the transcript #513 brought in a call to a command this PR removes; its wire wait is gone and the server-state read it was sequencing is now the barrier.beforeLoadguard in product code.Closes #339
