Introduces a new `exp` firmware variant on top of JB and ports the
`hv_vmm_present` sysctl rename to it.
Variant infrastructure
----------------------
- Adds `case exp` to `FirmwarePipeline.Variant`,
`VPhoneCLI.PatchFirmwareCLI.VariantOption`, and
`VPhoneVirtualMachine.Variant`. Every `switch variant` block in
`FirmwarePipeline.buildComponentList` includes the new case.
- Adds `make fw_patch_exp` + `make cfw_install_exp` Makefile targets
and an `EXP=1` flag for `make setup_machine`, mutually exclusive with
`JB=1` / `DEV=1` / `LESS=1`. `SPOOF_BUILD` env var is threaded
through for later use by the build-version step.
- Adds `--exp` to `scripts/setup_machine.sh` alongside `--jb` /
`--dev` / `--less`. The post-install JB-Finalize block also fires
for EXP (since EXP inherits the JB rootfs deployment).
- Adds `scripts/cfw_install_exp.sh` as the EXP install script
starting point: identical phase set to `cfw_install_jb.sh` (JB-1..JB-5)
with banner/header/footer updated for EXP. Subsequent commits in this
branch add the EXP-only experimental phases on top.
- Updates the variants table in `AGENTS.md` / `README.md` and the
three translated READMEs to include the new `Experimental (EXP)`
row, plus a paragraph describing what EXP adds on top of JB.
Kernel patch
------------
- New `KernelEXPPatcher` orchestrator in
`sources/FirmwarePatcher/Kernel/`, chained after `KernelPatcher` +
`KernelJBPatcher` for the `.exp` variant only. Inherits
`KernelJBPatcherBase` to reuse the JB symbol-table / ADRP-BL index /
branch-encoder infrastructure.
- New `KernelEXPPatchHvVmmRename` patch in
`sources/FirmwarePatcher/Kernel/EXPPatches/`. Part A flips byte 0 of
the NUL-delimited `\\0hv_vmm_present\\0` cstring (the sysctl OID's
`oid_name` value) — `'h'` -> `'X'` — so the kernel resolves
`sysctlbyname("kern.hv_vmm_present")` as ENOENT and
`sysctlbyname("kern.Xv_vmm_present")` to the OID's real int value.
Part B mangles byte 5 of every kernel-internal occurrence of
`kern.hv_vmm_present` so callers keep hitting the renamed OID; two
byte-aligned forms are covered (NUL-delimited cstring + sandbox-profile
name-token with trailing `\\x0f`).
- Patch IDs are `kernelcache_exp.hv_vmm_oid_rename` and
`kernelcache_exp.hv_vmm_internal_caller_mangle`. Idempotent.
- `KernelJBPatcher` is unchanged at the call-site level (no
`patchHvVmmRename` call); its docstring is updated to point at
`KernelEXPPatcher` for the EXP-only patch.
JB and other variants are NOT affected: `cfw_install_jb.sh` and
`cfw_install_dev.sh` are untouched in this commit.
Make the default clean target remove only build/tooling artifacts, add
confirmation prompts, and require explicit CLEAN_VM/CLEAN_IPSW flags before
removing VM or IPSW state. Document the behavior in README translations.
* Fix iproxy port number for SSH connection
* Fix iproxy port number in README_zh.md
* Fix iproxy port number in Japanese README
* Fix iproxy port number in README_ko.md
* fix: prefer project venv Python for patchers
* add: VM backup, restore, and switch support
Named backups via rsync --sparse for efficient sparse disk handling.
- vm_backup.sh: save current VM as a named backup to vm.backups/
- vm_restore.sh: restore a named backup into vm/
- vm_switch.sh: save current + restore target in one step
- Makefile targets: vm_backup, vm_restore, vm_switch, vm_list
- Documentation added to all READMEs (EN, ZH, KO, JA)
Closes#204
Made-with: Cursor
Implement VM configuration manifest system compatible with security-pcc's
VMBundle.Config format, storing VM settings in config.plist.
**Manifest System:**
- Add VPhoneVirtualMachineManifest.swift with security-pcc compatible structure
- Add scripts/vm_manifest.py for manifest generation during vm_new
- Update VPhoneCLI to support --config option with CLI overrides
- Update vm_create.sh to generate config.plist with CPU/memory/screen settings
**Environment Variables:**
- CPU/MEMORY/DISK_SIZE now only used during vm_new (written to manifest)
- boot/boot_dfu automatically read from config.plist
- Remove unused CFW_INPUT variable (overridden by scripts internally)
- Document remaining variables with their usage scope
**Documentation:**
- Update README.md with VM configuration section
- Update docs/README_{zh,ja,ko}.md with translated VM configuration docs
- Update Makefile help output with vm_new options and config.plist usage
- Fix fw_patch_jb description: "dev + JB extensions"
- Fix restore_get_shsh description: "Dump SHSH response from Apple"
**Code Quality:**
- Add VPhoneVirtualMachineRefactored.swift demonstrating code-clarity principles
- Extract 200+ line init into focused configuration methods
- Improve naming: hardwareModel, graphicsConfiguration, soundDevice
- Add BatteryConnectivity enum for magic numbers
- Create research/manifest_and_refactoring_summary.md with full analysis
**Compatibility with security-pcc:**
- Platform type: Fixed vresearch101 (iPhone-only)
- Network: NAT only (no bridging/host-only needed)
- Added: ScreenConfig and SEP storage (iPhone-specific)
- Removed: VirtMesh plugin support (PCC-specific)
docs: add machineIdentifier storage analysis
Research and validate the integration of machineIdentifier into config.plist.
**Findings:**
- security-pcc stores machineIdentifier in config.plist (same approach)
- VZMacAuxiliaryStorage creation is independent of machineIdentifier
- VZMacMachineIdentifier only requires Data representation, not file source
- No binding or validation between components
**Conclusion:**
- ✅ No compatibility issues
- ✅ Matches security-pcc official implementation
- ✅ Proper handling of first-boot creation and data recovery
- ✅ Safe to use
Delete VPhoneVirtualMachineRefactored.swift
refactor: integrate machineIdentifier into config.plist
Move machineIdentifier storage from standalone machineIdentifier.bin file
into the central config.plist manifest for simpler VM configuration.
**Changes:**
- VPhoneVirtualMachineManifest: Remove machineIDFile field
- VPhoneVirtualMachine: Load/create machineIdentifier from manifest
- VPhoneCLI: Remove --machine-id parameter, require --config
- Makefile: Remove --machine-id from boot/boot_dfu targets
- vm_manifest.py: Remove machineIDFile from manifest structure
**Behavior:**
- First boot: Creates machineIdentifier and saves to config.plist
- Subsequent boots: Loads machineIdentifier from config.plist
- Invalid/empty machineIdentifier: Auto-regenerates and updates manifest
- All VM configuration now centralized in single config.plist file
**File cleanup:**
- Move VPhoneVirtualMachineRefactored.swift to research/ as reference

- Fix JB boot chain patch count: 66/78 → 112 (per research doc)
- Merge PR #148: remove cfw_install_jb_finalize, update SSH to openssh-server
- Keep dropbear instructions for Regular/Dev variants
- Add Option 2 (amfidont) to prerequisites and FAQ in all translations
- Add setup_machine options comment to all translations
- Add .tipa FAQ entry (from #142) to all translations
- Add openssh-server FAQ entries to all translations
- Run prettier on all docs
JB setup now runs automatically on first boot. SSH access is via
openssh-server from Sileo instead of dropbear. Update all READMEs
(en, zh, ja, ko) accordingly.

- Replace Python cfw_inject_dylib.py with tyilo/insert_dylib (built by setup_tools)
- Use --weak flag for LC_LOAD_WEAK_DYLIB injection (avoids crash on missing dylib)
- Preserve original launchd entitlements on re-sign (fixes "operation not permitted")
- Deploy dylibs from pre-built basebin payload instead of building from source
- Remove launchdhook, systemhook, treblehook sources (no longer needed)
- Print GDB debug stub port after VM starts
- Cleanup: remove test scripts, rename patch comparison doc
