Summary

On a Mac with more than one logged-in account, every account's daemon shared the /tmp runtime files and the machine-wide port 19222, so the second account's CLI failed with a misleading "could not restore its runtime files". This release gives each account its own daemon: runtime files in that account's temporary directory, an IPC/WebSocket port pair derived from the uid (derivePorts in shared/platform.ts; the primary account keeps 19221/19222), a loopback-only bind, and an error that names the other account's daemon when a port is genuinely held. The extension adopts the port from the native host's pong, and the native agent and Safari appex compute it from getuid(). The pkg postinstall stops every account's daemon and removes the legacy /tmp files.

An account with no launchd GUI session (ssh, a service account) used to get a hint blaming the postinstall and suggesting a launchctl bootstrap that cannot work there. shared/gui-session.ts now probes launchctl print gui/<uid>; when the session is absent, interceptor status, the daemon's macos error, and the daemon log name the account, the missing session, and who owns the screen, and the recovery ladder emits no launchctl actions. A present session with an unloaded LaunchAgent keeps the bootstrap guidance.

Versions move to 1.0.3 across the CLI, both extension manifests, the iOS runner, the Safari project, and the release notes.

Validation

  • Bun 1.4: 1,768 pass, 9 skip, 0 fail across 190 files (test/gui-session.test.ts, test/platform-runtime.test.ts, test/ws-endpoint.test.ts are new).
  • TypeScript typecheck (host, extension, root): pass. Capability-blind audit: pass.
  • Bridge: swift build clean; PlatformPortTests (new) and ExtensionFabricTests pass.
  • Live, on two Macs: two accounts logged in at once each keep their own daemon, bridge, and port pair; 21 interceptor macos verbs on both bridge routes, status, init, diagnose, and a browser open/close pass as each logged-in account; three accounts without a GUI session get the honest hint from status and a sub-second honest error from macos; unloading the LaunchAgent while logged in still recovers through bootstrap then kickstart.
  • Public diff scan: no internal planning references, personal filesystem paths, account names, host names, email addresses, or session identifiers in the added lines.

Closes #276. Ships the loopback half of #274; the Origin check there stays open.

Summary by CodeRabbit

  • New Features
    • Added per-account macOS daemon support with isolated runtime files and automatically assigned loopback ports.
    • Browser and Safari integrations now discover and reconnect to the correct account-specific port.
    • Added clearer diagnostics for missing screen sessions and daemon conflicts involving another account.
  • Bug Fixes
    • Runtime files and event logs now use user-specific temporary directories instead of shared paths.
    • WebSocket connections are restricted to local loopback addresses.
  • Release
    • Updated the application and extensions to version 1.0.3.

… without a GUI session (1.0.3)

Each logged-in macOS account now runs its own daemon: the socket, pid, lock,
log, and event files live in that account's temporary directory, and the
IPC/WebSocket pair is derived from the uid (`derivePorts` in shared/platform.ts;
the primary account keeps 19221/19222). The daemon binds 127.0.0.1 only. The
extension adopts its account's port from the native host's pong, the native
agent and the Safari appex compute it from getuid(), and a port held by another
account's daemon produces an error that says so. The pkg postinstall stops every
account's daemon and removes the legacy /tmp files.

An account with no launchd GUI session (ssh, service account) now gets a bridge
hint and error that name the account, the missing gui/<uid> session, and who
owns the screen (shared/gui-session.ts); the recovery ladder emits no launchctl
actions there. An account with a GUI session and an unloaded LaunchAgent keeps
the bootstrap guidance.

Versions move to 1.0.3 across the CLI, both extension manifests, the iOS runner,
the Safari project, and the release notes.

Closes #276.

Per-account daemon isolation

Layer / File(s) Summary
Runtime paths and port contracts
.agents/..., shared/..., cli/commands/..., interceptor-agent/..., interceptor-bridge/..., test/..., README.md, ARCHITECTURE.md
Runtime files now use per-user temporary directories. IPC and WebSocket ports derive from the account UID, with environment overrides and legacy /tmp detection.
Per-account WebSocket routing
daemon/index.ts, extension/src/background/..., extension/dist-mv2/background-electron.js, safari/..., scripts/build.sh, test/...
The daemon binds to 127.0.0.1 and reports its WebSocket port. Native hosts, the extension, and Safari compute or adopt the account-specific port.
GUI-session and ownership recovery
shared/gui-session.ts, shared/daemon-health.ts, daemon/..., cli/..., test/..., AGENTS.md, ARCHITECTURE.md
Recovery detects missing GUI sessions and foreign daemon processes. Status and error messages identify the account, GUI domain, and screen owner.
Release and daemon lifecycle updates
package.json, manifests, project files, scripts/release/..., scripts/uninstall.sh, docs/release-notes.html, extension/dist-mv2/..., test/release-notes-onboarding.test.ts
Version metadata changes to 1.0.3. Installation stops all matching daemons and removes runtime files. Uninstall cleanup includes per-user and legacy lock files.

Merge Risk: 🟠 High · up to ac1c0

Local accounts may access or connect to the wrong account’s daemon, while several supported configurations can fail to reach their own daemon. These issues should be fixed before merge.

Explanation

The implementation covers the main coding requirements in #276. It adds per-account runtime paths and UID-derived ports, loopback binding, port propagation for the extension, native agent, and Safari appex, cross-account conflict errors, all-account postinstall cleanup, GUI-session-aware recovery, bootstrap preservation for present sessions, and 1.0.3 version updates. The added tests cover these behaviors. The supplied evidence does not establish signing, notarization, installation, or update-feed verification for the release artifacts. The excluded generated path ios/InterceptorRunner/Generated/InterceptorRunner-Info.plist also cannot be inspected, so the final iPhone runner artifact version is not independently verifiable.

Resolution

Provide reviewable evidence that the 1.0.3 release artifacts pass signing, notarization, installation, and update-feed verification. Provide an independent check of the excluded iPhone runner artifact, or another reviewable source that proves its reported version is 1.0.3.

require an account-bound capability before accepting connections or invoking
action handlers, rather than trusting the loopback hostname or deterministic
UID-derived port. Generate and validate the capability through an owner-only
runtime-directory location, and use the Unix socket for account-local control
where supported.

In `@extension/src/background/ws-endpoint.ts`:
- Line 7: Update the WebSocket fallback flow in connectToHost and
connectWsChannel so it resolves the current account’s derived port before
connecting instead of using the default wsPort value. Preserve the per-account
daemon contract by either dialing the account-specific port or failing when that
port cannot be determined; never silently fall back to DEFAULT_WS_PORT.
- Line 34: Update the session restore flow around adoptWsPort so it records a
generation when the storage read begins and applies the restored wsPort only if
that generation is still current, preventing a newer native port adoption from
being overwritten or triggering a stale reconnect.

In `@safari/InterceptorSafari/InterceptorSafari`
Extension/SafariWebExtensionHandler.swift:
- Around line 55-57: Update SafariWebExtensionHandler’s WebSocket port selection
to use the daemon’s resolved INTERCEPTOR_WS_PORT value, passing that value into
the appex as needed instead of always deriving 19222 + 2 * slot from getuid();
alternatively, explicitly reject INTERCEPTOR_WS_PORT for Safari so the daemon
and appex cannot select different endpoints.

In `@shared/platform.ts`:
- Around line 58-61: Update legacyDaemonTemp to verify that the live PID belongs
to an Interceptor daemon after the existing kill(pid, 0) check and before
returning LEGACY_DAEMON_TEMP; return null when the identity check fails,
preserving the current invalid or non-signalable PID behavior.
- Around line 43-45: Update derivePorts so distinct supported UIDs, including
501 and 1001, do not map to the same IPC/WS port pair; use a sufficiently large
collision-resistant allocation range and preserve deterministic per-user
mapping. Ensure cli/daemon-spawn.ts can handle any remaining bind conflict
through port discovery or explicit recovery.

Require an account-bound credential on the WebSocket server. startWsServer() upgrades every loopback request without checking the peer account, origin, or capability. A process from another macOS account can connect to the deterministic UID-derived port, enumerate contexts, and invoke WebSocket action handlers. Authenticate the request before upgrade or dispatch. Store the capability in the owner-only runtime directory. Use the Unix socket for account-local control where possible.

Do not use the primary port as the no-native fallback.

When native messaging is unavailable, connectToHost() calls connectWsChannel(), which uses wsPort. On a fresh worker, wsPort remains 19222 unless a previous native pong was restored. shared/platform.ts derives a different port for secondary accounts, so the extension can connect to the primary account's daemon. This violates the per-account daemon contract.

Resolve the account-specific port before direct WebSocket use, or fail and require account-specific native messaging. Do not silently dial 19222.

Guard the session restore against a newer native port.

transport.ts:44 starts restoreWsPort() without awaiting its chrome.storage.session.get() promise. background.ts:34 then calls connectToHost(). A native pong can call adoptWsPort() before the storage read settles, after which this pending callback can overwrite the native port and reconnect the WebSocket lane to stale state.

Track a generation when the read starts. Apply the restored port only if no newer native port was adopted after that read began.

Avoid UID-slot collisions.

derivePorts() maps UID 501 and UID 1001 to the same port pair because PORT_SLOTS is 500. The repository test explicitly asserts this mapping. If both accounts run daemons, the second daemon cannot bind WS_PORT, and cli/daemon-spawn.ts fails instead of selecting another pair.

The documented wrap acknowledges a capacity limit, but it does not preserve the stated one-port-pair-per-user contract or provide adequate recovery. Use a larger supported range with collision-resistant allocation, or add per-user port discovery and conflict handling.

Validate the process identity before selecting /tmp.

When the per-user socket is absent, resolvePlatformConfig calls legacyDaemonTemp for non-Windows runs without an explicit temp directory. The default kill binding is process.kill; kill(pid, 0) confirms only that the PID is signalable. If a stale /tmp/interceptor.pid names an unrelated process owned by the current account, the function returns /tmp.

ensureDaemon then uses /tmp for the socket, PID, lock, log, and event paths. It can clear those paths and start the current daemon there, instead of using the account-specific runtime directory. It can also treat stale /tmp runtime state as current state.

Check that the live PID belongs to an Interceptor daemon before returning LEGACY_DAEMON_TEMP.

Proposed direction
     kill(pid, 0)
+    if (!isInterceptorDaemon(pid)) return null
     return LEGACY_DAEMON_TEMP
