Closes #354.

What

Deletes apps/conciv/test/helpers/fake-core.ts (243 lines) and fake-core-router.ts (107 lines) — the hand-maintained reimplementation of the core API (oRPC envelope, SSE framing, canned routes) — and migrates every consumer onto a real core booted per test file. Also migrates draft-storage.test.ts, which the issue missed but violated the same acceptance criteria (fetch monkeypatch + hand-encoded envelope).

How

  • Boot: vitest browser commands boot bootCoreKit (real makeApp, fake harness only) node-side per file; tests point window.__CONCIV_API_BASE__ at it. Warm boot is ~37ms; the suite got faster (41.7s total).
  • Interception: playwright page.route via the command context, through extended rpc-fault.ts helpers — releasable gates, injected 500s, transport aborts (TypeError, never a synthesized 500 — reachability classification is under test). Handle registry + exact-handler unroute teardown.
  • Run timing: scripted harness (hold/release/scriptError, new scriptTurn for multi-tool turns).
  • State: drafts via real drafts/set; external sessions + message counts via new fake-harness transcript-history fixtures flowing through core's real adoption path; running = an actual held run.
  • Core change (changeset): engine staleness became an injected probe on makeApp (default unchanged), threaded through rpc + /health + mcp, with a test that all three agree.
  • Terminal extension (changeset): createTerminalExtension({openTerminal}) seam — homed there because the core-purity lint rule forbids terminal vocabulary in core. Default export unchanged.

Acceptance criteria

  • fake-core.ts / fake-core-router.ts deleted (plus the fakeCoreSocket vite plugin and fake-core-socket.browser.test.ts, which tested the fake itself; ws-transport coverage lives in transport-standalone.it.test.ts)
  • No globalThis.fetch assignment under apps/conciv (repo-wide grep clean)
  • No hand-encoded {json, meta} envelope or SSE frame literals in test code
  • All migrated tests boot core through the testkit; per-test assertion inventories kept behavior assertions exact — reshapes are wire-level only and listed below
  • Nothing needed a partial fake

Deliberate test-contract notes

  • holdSnapshot ("stream open, snapshot withheld") is not expressible without re-parsing oRPC frames — the emulation this PR deletes. Reframed to "subscribe request held ⇒ skeleton / no marker-divider flash; release ⇒ real snapshot hydrates".
  • The old outage tests passed on accidental timing: outage detection is actually driven by the debounced drafts/set write failing, not the SSE stream. Migrated tests force that write deliberately.
  • quick-add's duplicate-resolve guard is now proven at the request boundary (gate holds, second click issues no request) instead of inspecting a fake's call array.
  • launch-actions asserts the real shell-quoted connect command instead of the fake's canned string.

Evidence

Full serial gates green at every phase: @conciv/app 142/142 (real Chromium), core 447, embed 114, harness-testkit/extension-testkit/terminal/client/contract suites, whole-repo typecheck, lint, format, fallow audit (zero introduced), changeset coverage.

…eams for browser tests

Core takes an injectable engine-staleness probe threaded through /health, rpc meta.engine and the mcp deps. bootCoreKit passes allowedOrigins, the staleness probe and harness transcript-history fixtures. createFakeHarness gains optional transcriptHistory rows, makeScriptedRun gains scriptTurn for multi-tool turns, and rpc-fault gains a releasable request gate plus preflight-aware, unroutable fault handlers. apps/conciv registers node-side vitest browser commands over those seams and proves the architecture with a held /rpc/chat/subscribe against a real booted core.

… core

chat-pane, session-selector, engine-staleness, launch-actions and
page-session-card boot a real core per file and drive it through the real
rpc surface: drafts seeded through drafts/set, held runs through the
scripted harness, transcripts produced by real turns, faults injected at
the playwright network layer. pane-harness takes the booted base and pins
the browser rpc transport to fetch.

Seams added along the way: an abort fault kind for transport failures, a
per-boot rpc observer for wire-call counts, a resume-capable fake harness
that reports the resumed session id instead of minting a new one, and
createTerminalExtension({openTerminal}) so terminal launches are testable
without spawning a real terminal window.

…real core

Drops installFakeCore from shell-harness and the six suites that used it:
per-route delays become releasable playwright gates, network failure becomes
a transport abort fault, and resolve/engine rejections become injected 500s.
Adds rpcMark/awaitRpcCall so a wire fact can be awaited instead of polled,
and lets an abort fault cover every rpc path.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
draft-storage boots a real core through bootCoreKit and verifies every write
through the real drafts/get row: no globalThis.fetch monkeypatch, no
hand-encoded {json, meta} envelope, no fake timers. The local proxy in front of
the kit gains a path-scoped refusal (the failed-initial-read path) and per-path
request counting (the debounce collapse), so faults land at the transport
boundary and payload assertions come from the database.

Deletes fake-core.ts, fake-core-router.ts, the fake-core-socket browser test
(websocket coverage lives in transport-standalone.it.test.ts and the
harness-testkit rpc suites) and the fakeCoreSocket vite plugin.

Sweeps: failRpcCalls only installs its websocket route when a caller asks for it
(playwright has no unrouteWebSocket, so an always-on handler accumulated across
files on the persistent vitest page); the client boot helper drops a dead
openTerminal option makeApp never accepted; apps/conciv drops the @orpc/server
devDependency the deleted fake router was the last consumer of.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
createRecordingTerminalOpener lost its last consumer when the client boot
helper stopped passing a dead openTerminal option to makeApp. Both testkits are
private, so the export is not public API: fallow traced it to a single barrel
re-export with zero references. The file carried nothing else.

📝 Walkthrough

Walkthrough

The PR removes the Conciv browser-test fake core and migrates tests to booted real-core instances. It adds injectable engine-staleness and terminal-opening seams, shared RPC fault controls, scripted turns, session helpers, and updated integration coverage.

Changes

Real-core testing and runtime seams

Layer / File(s) Summary
Runtime dependency seams
packages/core/..., packages/extensions/terminal/src/server.ts, packages/client/test/helpers/boot.ts, .changeset/*
makeApp accepts an injectable staleness provider. Health, RPC metadata, and MCP instructions use it. Terminal creation accepts an optional openTerminal callback.
Core testkit and RPC fault controls
packages/extension-testkit/..., packages/harness-testkit/..., packages/embed/tests/e2e/*
The testkit supports real-core options, scripted turns, session history, WebSocket faults, HTTP aborts, and gated RPC requests.
Browser core-control harness
apps/conciv/test/commands/*, apps/conciv/test/helpers/*, apps/conciv/vitest.config.ts
Browser commands boot and close cores, create sessions, control turns, observe RPC calls, configure terminal launches, and manage faults. Harnesses use dynamic API bases and clean up connections.
Core-backed interaction tests
apps/conciv/test/chat-pane.browser.test.tsx, draft-storage.test.ts, engine-staleness.browser.test.tsx, launch-actions.browser.test.tsx, page-session-card.browser.test.tsx, session-selector.browser.test.tsx, core-request-gate.browser.test.ts
Tests use real sessions, streams, drafts, engine state, scripted turns, and injected RPC faults.
Core-backed panel and navigation tests
apps/conciv/test/panel-*.browser.test.tsx, quick-add-pane.browser.test.tsx, reachability-flows.browser.test.tsx, route-boundary.browser.test.tsx
Panel, routing, reachability, quick-add, focus, and loading tests use real-core requests and request gates instead of fake-core state.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 45dde

The test migration adds stateful fault interception and terminal-launch assertions, but failures can leave injected faults active for later tests, while one assertion depends on test order. This can cascade or mask test failures, so merge should wait for failure-safe cleanup and order-independent assertions or explicit owner acceptance.

apps/conciv/test/reachability-flows.browser.test.tsx (1)

35-121: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Installed faults are released only on the success path in five migrated test files. Each test releases its fault in the last statement of the test body. A failed assertion aborts the body and skips the release. closeCore disposes faults only after the whole file finishes, so the leaked route interception stays active for every later test in that file and turns one failure into cascading failures. apps/conciv/test/chat-pane.browser.test.tsx lines 32-36 already wraps coreControl.installFault and tracks handles; reuse that pattern in a shared helper.

  • apps/conciv/test/reachability-flows.browser.test.tsx#L35-L121: track every handle and release it in afterEach; the unpathed {kind: 'abort'} faults at lines 36, 73, and 112 block createSession for all later tests if they leak.
  • apps/conciv/test/panel-connect.browser.test.tsx#L57-L80: track the abort and HTTP 500 sessions.resolve handles and release them in afterEach instead of relying on expectRetryRecovers.
  • apps/conciv/test/panel-focus-stability.browser.test.tsx#L31-L45: track the gate handle before vi.waitUntil and release it in afterEach, because a rejected wait skips the release at line 37.
  • apps/conciv/test/quick-add-pane.browser.test.tsx#L29-L63: track the three fault handles and release them in afterEach.
  • apps/conciv/test/route-boundary.browser.test.tsx#L33-L70: track the captures.list, sessions.list, and sessions.resolve gate handles and release them in afterEach.

57-57: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

The strict === 1 wait can pass while a second request is still in flight.

faultPending(held) reaches 1 as soon as the first resolve request arrives. The wait then succeeds even if the second click produces a second request moments later. The pane-count assertions at lines 61-62 remain the real guard, so consider waiting for the pane count instead of the pending count, or assert the pending count again after the gate settles.

Release the injected fault in afterEach.

Line 120 releases the fault only when the assertion at Line 118 passes. If that assertion fails, the fault stays installed for the rest of the file. chat-pane.browser.test.tsx solves this with a tracked installFault helper plus an afterEach release. Reuse that pattern here.

♻️ Proposed cleanup hook
 const core = {base: ''}
 const mounted: {pane: PaneMount | null} = {pane: null}
+const faults: string[] = []

 afterEach(async () => {
+  for (const fault of faults.splice(0)) await coreControl.releaseFault(fault)
   mounted.pane?.dispose()
   mounted.pane = null
   await coreControl.setTerminalLaunch(true)
 })

Then push each handle in the test instead of releasing it inline.

the neighboring browser tests.

42-46: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Make the terminal-launch count independent of the test order.

coreControl resets terminal.launches only in closeCore. The counter therefore accumulates for the whole file. The assertion at Line 84 uses an absolute value of 1, so it holds only while no earlier test triggers a launch. The test at Line 88 also increments the counter, because the injected openTerminal increments before it returns false. The neighboring tests already use the delta pattern at Line 91 and Line 102.

Use the delta pattern for launches as well, or reset the counter in afterEach.

♻️ Proposed change to the delta pattern
 test('the terminal opens the harness through the extension', async () => {
+  const before = await coreControl.terminalLaunches()
   await mountActions()

   await openMenu()
   await page.getByText('Open in Claude').click()

   await expect.element(page.getByText('Opened in Claude.')).toBeVisible()
-  expect(await coreControl.terminalLaunches()).toBe(1)
+  expect((await coreControl.terminalLaunches()) - before).toBe(1)
   expect(await coreControl.rpcCallCount(LAUNCH_PATH)).toBe(1)
 })

Note: the rpcCallCount(LAUNCH_PATH) assertion on the same line has the same order dependency. Apply the delta pattern to it too.

Also applies to: 84-84

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Do not lose fault handles when cleanup fails.

If coreControl.releaseFault(handle) rejects, handles.splice(0) removes every handle before the loop starts. The loop stops at that rejection. The rejected handle and all later handles are no longer available for retry. This can leave fault injection active for later tests. Attempt every release, retain failed handles, and rethrow the first cleanup error.

Proposed cleanup handling
   const releaseAll = async (): Promise<void> => {
-    for (const handle of handles.splice(0)) await coreControl.releaseFault(handle)
+    const pending = handles.splice(0)
+    let failed = false
+    let firstError: unknown
+    for (const handle of pending) {
+      try {
+        await coreControl.releaseFault(handle)
+      } catch (error) {
+        handles.push(handle)
+        if (!failed) {
+          failed = true
+          firstError = error
+        }
+      }
+    }
+    if (failed) throw firstError
   }

coreControl.releaseFault(handle) succeeds, retain rejected handles for retry,
and rethrow the first cleanup error after all releases have been attempted.

Copilot review findings on #508.

The draft-storage suite polled `rpc.drafts.get` to wait out the 300ms
debounced fire-and-forget write. The proxy the test already routes
through knows exactly when a write completed, so it now exposes
`mark()`/`awaitRequest(pathname)` resolved from its own response-finish
event; every `expect.poll` becomes one armed wait plus one plain
assertion. No product signal was added.

`gateRpcCalls` gained `awaitCaptured(count)`, fulfilled at the capture
site, threaded to the browser through a new `awaitFaultPending` command
that keeps AWAIT_RPC_TIMEOUT_MS purely as a failure deadline. That
retires the `vi.waitUntil(faultPending)` polls; `faultPending` stays for
the direct-fact assertions in core-request-gate.

…508)

scriptTurn defaulted result with ??, so an explicitly scripted null tool
result serialized as {"ok":true}. Default only on undefined.

panel-focus-stability released the request gate before the editor node and
its focus were captured, so the gated request could complete before capture
and the test no longer proved that an already-focused composer survives a
pending dependency completing. The two "still loading" tests now capture and
assert focus while the fault is still pending, then release. The draft-load
test keeps its own shape: the composer lives behind a Show on the drafts.get
resource, so it cannot mount until that request completes.

…ublicPackages entry (#509)

* chore: #508 follow-ups — scope session invalidation, drop stale fallow publicPackages entry

invalidateSessions invalidated the whole sessions router key, so every pane
add/close/new-session refetched the warm sessions.resolve query in the root
chrome as well as the list it actually changes. The warm resolve keys off the
latest session row, so it already refetches on its own when that row moves;
the extra round-trips were pure waste (measured: 3 resolves per quick add/close
flow instead of 1).

.fallowrc.json listed @conciv/harness-testkit under publicPackages, but the
package is private and absent from PUBLIC_PACKAGES. Removing the entry surfaced
two exports in run-events.ts that only have in-file callers; they are now module
private.
