The supervisor survives command exit. Queued cancellation is checked before admission, timeouts include queue time, and completion waits for descendant teardown/reaping. The core uses dedicated pthreads; guest `pthread_exit` must never run on a GCD worker. The original probe caught that lifecycle mistake natively. + +The original unmodified iSH probe reproduced `mount -t real` exposing a controlled host directory.

A process-wide coordinator owns jobs, admission and the journal across React Native bridge generations; invalidating a generation cancels only its commands and prevents new admission through that module. Guest files and fakefs metadata always change through iSH. Pi's portable file adapter is backed by controlled guest filesystem commands, never by writing directly into fakefs `data` through Expo. + +`src/runtime/ish.ts` implements shell strings/argv, cwd/env, independent UTF-8 stream decoders, cancellation, spill files, binary file tools, no-follow reader checks, flush and bounded polling watchers. Complete file operations serialize with shell operations. Polling watches can miss changes that occur and are undone between polls, and wait behind a running guest command. Pi `bash` uses the guest POSIX `/bin/sh`; Bash extensions and unsupported Linux syscalls are not promised. Network access is unavailable. + +## Durability and limits + +Pi shell tools are explicitly `replay: unsafe`. Before shell effects, the tool stores a stable native command ID with Pi's durable `api.memo`. The native journal stores only ID/workspace/status/exit code, never argv, stdin, environment or model credentials. IDs are never evicted or automatically re-executed. A running record becomes interrupted when the process-wide coordinator first opens after process death; malformed/unreadable journals disable execution. File contents persist, but CPU state and a killed process cannot be resumed. The existing Pi transcript records interrupted unsafe tools; the user can deliberately rerun with a new submission. + +- Pi file transfers: 8 MiB per file, inherited from the portable file adapter. +- Native capture: 16 MiB combined stdout/stderr; overflow cancels and reports an error. Input: 16 MiB per command, 32 MiB across admitted jobs. +- Native admission: four jobs, including queued jobs and pending promise settlements. Busy rejection happens before guest effects or journaling. +- Journal and pre-registration cancellation sets: 10,000 IDs each, fail closed at capacity.

File tools and shell commands operate through the same core, with explicit argv/environment and stdin/stdout/stderr. There is no companion-service installation, public-key exchange or external terminal launch. + +The native coordinator serializes guest execution, bounds admission/output/resources, cancels command-domain descendants and retains a persistent command-ID journal. The Pi bash wrapper records durable intent before effects and does not automatically replay unsafe commands. Guest networking and host filesystem mounts are disabled. Model credentials remain in Moose secure storage and are not inherited by the guest. + +The interpreter shares the Moose OS process; it is not a separately sandboxed VM. See [execution and licensing notes](ios-ish-execution.md) for the exact source pin, resource bounds and corresponding-source obligations before distributing any linked binary, even with the runtime flag disabled. + +## Acceptance record + +Record the Moose version/commit, Mac architecture, Xcode and iOS versions, simulator/device model, preparation result, native build/signing result and enabled flags. Then record file/shell interoperability, Stop, separate conversations, checkpoint branches, file persistence after restart and return to the default backend. + +Record host tests, Hermes exports, simulator operations, physical-device operations and real model requests separately. For a physical device, separately test foreground use, switching apps, lock/unlock and reopening, preserving status and errors without assuming uninterrupted background progress. No completed physical-device acceptance is claimed by this guide. + +## Diagnostics + +There is currently no iOS equivalent of Termux's **Run self-check (no model calls)** or **View diagnostic records** settings buttons. Use the controlled developer smoke and native verification commands above. Preserve displayed errors and tool results; do not include API keys, OAuth tokens or private file contents when sharing a report. + +## Simulator validation, 2026-10-23 + +Rechecked code commit `07411e8` (Moose v0.7.0) on an Apple Silicon Mac with Xcode 26.2 (17C52), Node.js 26.8.1 and an iPhone 17 Pro simulator running iOS 26.2. The Mac already had the documented tools installed; this was not a clean-Mac prerequisite installation test. + +| Layer | Result from this run | +| -------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| Dependency preparation | `npm run prepare:ish` completed using its default `/tmp/moose-ish-embedded` cache, producing device/simulator libraries, the XCFramework and rootfs. | +| Installed resources | The installed app's native source manifest matched the current core, policy patch and bridge sources; the guest rootfs and BusyBox were present. | +| Native Moose client | Rebuilt and installed with iSH enabled: build succeeded with zero errors and 11 warnings. The controlled Metro session used port 8097. | +| Host and Pi adapter verification | `npm run test:ish` passed the real host core and production bridge suites, plus all 33 adapter/boundary tests. These are host results, not simulator test counts. | +| UIKit core | Real same-kernel suite passed with roots, argv/env/streams, supervisor survival, descendant cancellation, timeouts and resource checks; the UIKit host survived. | +| UIKit production bridge | Passed binary stdin/output, 8 MiB transfer, event ordering, cancellation/timeout/flood bounds, command IDs, admission limits and cross-generation journal/invalidation. | +| React Native/Hermes app | With both iSH and file-smoke flags enabled, the app displayed `Moose filesystem smoke passed` after controlled SSE drove Pi write/edit/bash/read. Tool results reached the next controlled request; transcript persistence, checkpoint isolation, file/SQLite reopen and traversal rejection passed. | + +This validates the prepared native backend and its Pi integration in the simulator's controlled developer entry. It does not validate a real model/provider account, the ordinary chat UI's complete model-configuration flow, physical-iPhone signing/installation, or locked-screen/background execution. No real model credentials or billable requests were used by the controlled tests. diff --git a/docs/mobile-feasibility.md b/docs/mobile-feasibility.md index cad8447..8c2cbf4 100644 --- a/docs/mobile-feasibility.md +++ b/docs/mobile-feasibility.md @@ -55,3 +55,7 @@ npm audit still reports 22 upstream findings in the installation tree, concentra ## Local Expo file environment integration Moose now injects the device filesystem through the npm-published `pi-durable-expo-env`, reusing Pi's read, write, and edit tools.

Contributions after the commit identified in `LICENSE.md`, and +identified authors' earlier contributions, are additionally licensed under GPL +version 2. That does not establish a GPLv2-only license for the complete source. +Preserve all upstream source notices and the full upstream license files. + +`embedded-policy.patch` is Moose's local modification to that pinned source: +it adds inherited execution domains, isolates mount selection by domain, +prevents guest host mounts, sockets, ptrace, privileged device/chroot operations, +cross-domain signals and cross-process resource-limit changes, and suppresses +setuid/setgid privilege changes at exec. `embedded.c` adds one surviving +supervisor, serialized command startup, explicit descriptors, domain cancellation +and reaping. The builder applies the patch only to a disposable copied source; +the pristine pinned checkout remains unchanged. + +Before distributing a linked binary, select a compatible whole-program license, +include complete applicable license texts and notices, and deliver complete +corresponding source with build instructions for the exact kernel, modifications, +frontend and bundled root filesystem packages. `LICENSE.IOS` retains source and +license-text obligations. Alpine packages have their own licenses and sources; +rootfs redistribution requires an additional package source/license manifest. +The current build outputs are local validation artifacts, not a distribution +license determination. See `docs/ios-ish-execution.md` for evidence and limits. + +The embedded policy also caps each active domain at 32 owned task slots (processes, threads and unreaped zombies +together), regular guest files at 16 MiB, and combined guest mapping +backing at 256 MiB. Shared COW backing counts once; private copies count when +allocated. Native syscall transfer buffers are separately bounded to 16 MiB, +with at most 1024 vector entries. These are explicit kernel-path checks, not +claims that upstream enforces RLIMIT_AS, RLIMIT_FSIZE, or RLIMIT_NPROC. The +mapping counter does not bound whole-process RSS, emulator/SQLite metadata or +all host allocations. There is no aggregate workspace disk quota.
