Summary

  • advertise clientCapabilities.auth.terminal and preserve typed ACP authentication methods
  • handle numeric auth_required results with bounded agent or terminal authentication flows
  • launch terminal authentication from the immutable agent launch snapshot, then reconnect and retry without calling authenticate
  • add onboarding/settings UI, typed IPC contracts, lifecycle integration, SDD, and focused regression coverage

UI

BEFORE

New ACP thread
  └─ session/new → auth_required → generic failure

AFTER

New ACP thread
  └─ session/new → auth_required
      └─ authentication dialog
          ├─ agent method → authenticate → retry
          └─ terminal method → embedded PTY → reconnect → retry
              └─ ready draft

Validation

  • pnpm run format
  • pnpm run i18n
  • pnpm run lint

📝 Walkthrough

Walkthrough

ACP terminal authentication is implemented across ACP runtime contracts, process management, PTY execution, typed IPC, session preparation, renderer onboarding, settings, localization, registry metadata, and regression tests.

Changes

ACP terminal authentication

Layer / File(s) Summary
Authentication contracts and runtime flow
src/shared/types/acp.ts, src/shared/contracts/routes/*, src/shared/contracts/events/*, src/main/agent/acp/runtime/*, src/main/agent/acp/auth/*
Adds authentication types, routes, events, launch snapshots, challenge ownership, PTY execution, cancellation, timeout handling, reconnect, and cleanup.
Application wiring and draft-session results
src/main/app/composition.ts, src/main/agent/acp/routes.ts, src/main/session/*, src/renderer/api/*
Injects AcpAuthService, replaces terminal routes, and returns discriminated ready or auth_required draft-session results.
Renderer authentication onboarding
src/renderer/src/pages/NewThreadPage.vue, src/renderer/settings/components/AcpSettings.vue, src/renderer/src/components/acp/AcpAuthDialog.vue, src/renderer/src/i18n/*/settings.json
Adds authentication inspection, method selection, PTY output and input, lifecycle state handling, cancellation, onboarding prompts, retry after success, and localized strings.
Specification and registry alignment
docs/features/acp-terminal-auth/*, docs/features/acp-v1-reliability/*, docs/README.md, resources/acp-registry/registry.json
Documents the implementation and updates ACP registry versions, archives, and checksums.
Regression coverage and supporting updates
test/main/*, test/renderer/*, docs/architecture/baselines/*, src/main/toolchains/stateStore.ts
Adds runtime, route, session, bridge, settings, dialog, and onboarding tests. Updates the renderer boundary baseline and quarantine filenames.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 7e07c

The terminal authentication flow can still accept an authentication challenge without tying it to the originating window, while reconnect failures may permanently prevent retry and cancellation failures may leave the dialog without feedback. These bounded issues affect authentication safety and recovery, so merge should wait for fixes or explicit owner acceptance.

Check name Status Explanation Resolution
Linked Issues check ⚠️ Warning The implementation does not meet #2144 because it explicitly avoids calling ACP authenticate after terminal authentication succeeds. Align terminal-auth completion with #2144 by calling ACP authenticate after successful terminal execution, then reconnecting and retrying session creation; update docs and tests.
Out of Scope Changes check ⚠️ Warning The PR includes unrelated state-store quarantine filename changes and broad registry version updates not required by #2144. Move the stateStore and unrelated registry changes to separate PRs, or document their direct dependency on ACP terminal authentication.
Docstring Coverage ⚠️ Warning Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Write docstrings for the functions missing them to satisfy the coverage threshold.

21-57: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Consider a maximum run duration for a terminal authentication run.

start creates a PTY with no lifetime bound. If the user leaves the dialog and the renderer is not destroyed, the child process runs until application shutdown. The linked issue asks for bounded terminal authentication flows. Add an upper bound on the run duration, or confirm that a bound exists in the caller.

140-202: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Guard finishTerminalAuthentication state writes against shutdown.

shutdown kills every PTY. Each pending finishTerminalAuthentication then resolves with cancelled: true, calls abandonAuthentication, and calls setStatus. setStatus calls sendToRenderer during application teardown. Confirm that sendToRenderer is safe after the renderer and runtime owner are gone, or add a disposed flag that suppresses post-shutdown status writes.

Inline comments:
In `@docs/features/acp-terminal-auth/plan.md`:
- Around line 20-21: Update the plan’s ownership path from the ACP launch
wildcard to the actual auth runner module boundary, referencing
acpTerminalAuthRunner.ts under the ACP auth area while preserving the
surrounding description.

In `@docs/README.md`:
- Line 36: Update the features/acp-terminal-auth entry in the README index to
mark the terminal-auth feature as implemented rather than pending, while
preserving the existing link and description.

In `@src/main/agent/acp/auth/acpAuthService.ts`:
- Around line 23-33: Update the challenge lifecycle across inspect, setStatus,
and getStatus so terminal states (succeeded, failed, and cancelled) no longer
allow unbounded growth of the statuses map. Remove terminal entries after the
process manager releases each challenge, or retain them only through a small
bounded LRU if getStatus must continue returning terminal results; preserve
required status lookup behavior.

In `@src/main/agent/acp/auth/acpTerminalAuthRunner.ts`:
- Around line 64-88: Update PTY termination in cancel and shutdown so the
initial kill is followed by a bounded POSIX-only escalation using
pty.kill('SIGKILL') if the process remains alive, while Windows uses IPty.kill
without a signal and its supported termination path. Ensure the escalation is
cancelled when onExit occurs, and add tests covering cancellation and shutdown
on both platforms through acpTerminalAuthRunner.

In `@src/main/agent/acp/runtime/acpProcessManager.ts`:
- Around line 751-785: Update claimAuthChallenge to reserve the challenge and
its scope before the Promise.all asynchronous validation, preventing concurrent
claims of the same challengeId; release both reservations when launch-signature
validation fails, while preserving existing stale, scope, and method checks. Add
a regression test covering concurrent starts for the same challenge ID.
- Around line 708-730: Update claimAuthChallenge to reject terminal
authentication when terminalAuthAvailable is false, before returning a claim
that can be used to spawn the launch. Ensure prepareTerminalAuthentication
inherits this rejection for unsupported terminal descriptors, and add coverage
that calls prepareTerminalAuthentication with terminal authentication disabled
and verifies it fails.

In `@src/renderer/src/components/acp/AcpAuthDialog.vue`:
- Around line 173-183: Update startAuthentication and the dialog lifecycle
cleanup to track an authentication-attempt token, invalidate it on every dialog
exit or unmount path, and cancel any active run during unmount. After
client.start resolves, cancel its returned runId when the token is stale before
creating or retaining the terminal, preventing a late response from leaving an
ownerless PTY.

In `@src/renderer/src/i18n/da-DK/settings.json`:
- Around line 1764-1782: Translate the ACP authentication strings while
preserving all keys and the {name} placeholder: update Danish in
src/renderer/src/i18n/da-DK/settings.json lines 1764-1782, German in

Apply the same fix in `@src/renderer/src/i18n/he-IL/settings.json` around lines
1831 - 1849: Same untranslated ACP authentication strings.

In `@test/main/agent/acp/auth/acpTerminalAuthRunner.test.ts`:
- Around line 4-7: Update the test setup around processEnvironment and
launch.env to set a parent-only sentinel, pass only a minimal launch
environment, and make the child fail if it receives the sentinel. Ensure the
original process.env is restored in a finally block after the test completes.

27-38: 🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift

Bind each challenge to its originating renderer before start.

inspect stores required without ownerWebContentsId. start only checks ownership after a challenge is already running or reconnecting. A different renderer can therefore start a known challenge ID and receive its terminal authentication output.

Record the IPC sender when every challenge is issued, including draft-session challenges. Reject a different sender before getAuthChallenge and before terminal launch preparation.

Proposed service-level guard
- async inspect(agentId: string, workdir?: string): Promise<AcpAuthChallenge> {
+ async inspect(
+   agentId: string,
+   workdir: string | undefined,
+   ownerWebContentsId: number
+ ): Promise<AcpAuthChallenge> {
    // ...
    this.rememberStatus({
      challengeId: challenge.id,
-     state: 'required'
+     state: 'required',
+     ownerWebContentsId
    })
  }

  async start(challengeId: string, methodId: string, ownerWebContentsId: number) {
    const current = this.statuses.get(challengeId)
+   if (
+     current?.ownerWebContentsId !== undefined &&
+     current.ownerWebContentsId !== ownerWebContentsId
+   ) {
+     throw new Error('ACP authentication is owned by another renderer')

[P1] The ACP SDK has no timeout or AbortSignal here and does not reject pending requests when the stream closes. A hung or crashed agent leaves the auth scope locked until restart; race this with timeout, connection close, renderer destruction, and shutdown, then release exactly once.

[P1] challenge.handle remains a reusable warmup while terminal login runs, so another session can bind it before this line. This can kill a newly active session; reserve the handle during auth or verify it is still the same unbound warmup under the binding lock before disposal.

[P2] Required challenges are stored without ownerWebContentsId, so another renderer that obtains this ID can start first and become the terminal owner. Bind the challenge when issued and enforce ownership before lookup/start.

[P2] Cancellation cleanup still depends on onExit. If kill() does not emit it, completion never settles and the auth scope remains locked; add a bounded fallback that settles and removes the run without the event.

[P2] A terminal stateChanged event can arrive before this older start response, after which these assignments move the UI back to running. Include a monotonic revision in responses and events and ignore stale updates.

[P2] If reconnect fails after the old handle is disposed, the unconsumed challenge still points to that dead handle, so every UI retry fails as stale. Consume or replace it and expose a fresh challenge/re-inspect path.

const dataSubscription = pty.onData((data) => {
for (let offset = 0; offset < data.length; offset += 65_536) {

[P2] Chunking limits individual IPC payloads but not total output or rate. A noisy auth process can build an unbounded main-to-renderer queue; add per-run backpressure, queue limits, and truncation or termination on overflow.

203-206: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Handle cancel failures in cancelAuthentication.

cancelAuthentication awaits client.cancel without a catch. If the route rejects, the click handler produces an unhandled rejection and the dialog shows no feedback. cancelRun already suppresses errors for the same call. Reuse it, or set error on failure.

♻️ Proposed fix
-async function cancelAuthentication() {
-  if (!runId.value) return
-  await client.cancel(runId.value)
-}
+function cancelAuthentication() {
+  if (!runId.value) return
+  cancelRun(runId.value)
+}
