Select an armv7h userspace for Orchard arm platforms and carry the target through desktop components, root assembly and release auditing. Check package metadata and native ELF headers before packaging, and isolate component caches by architecture and compiler identity. Build ARMv7 Omacalc from its pinned upstream source and use the selected Cascadia board profile for recovery assembly. The ARMv7 producer contract is supplied by the companion Orchard change. Assisted-by: LLM
Verify the official bootstrap archive against its pinned hash and published signing key before importing it into the selected Podman connection. Prepare the native compiler and Qt build dependencies, then record the compiler image ID and package versions. The recipe uses an existing ARM32 execution environment and leaves emulator registration and the host default connection to the host owner. Assisted-by: LLM
Retain Arch hardening defaults while omitting RELR packing, which the ARM32 linker rejects. Compile and execute a check with the resulting makepkg flags when preparing the image. Assisted-by: LLM
Require the selected platform input to supply a native static mapper for an LwVM root before compiling the desktop. Pass that helper and the selected rescue tools to installed initrd and RAM recovery assembly. Assisted-by: LLM
Keep explicit device selection consistent with the selected input boards before choosing their loader and storage tools. Assisted-by: LLM
Check the known keymap data directory for framed ELF64 BPF relocatable objects before enforcing the native root ABI. Preserve rejection of foreign native objects and malformed or misplaced bytecode during assembly and audit. Assisted-by: LLM
Keep the ARM64 platform index and block-root producer while sending ARMv7 through its board-selected layer and recovery producers. Check the native CLI contract before resolving expensive inputs, and forward the static mapper and rescue tools. Bind source snapshots and component keys to the build receipt. Measure consumed files before assembly and verify them afterward, preserve archive-tree provenance, and keep base and final release stamps distinct. Filter published layer fields through the schema contract. Keep generic installer packaging scoped to its supported ARM64 path while native asset qualification remains pending. Assisted-by: LLM
Keep the temporary Orchard checkout confined to the early-contract test so later publication cases resolve their real source snapshot. The complete host suite passes 186 cases with 22 artifact skips. Assisted-by: LLM

A private build umask made newly staged system and home parents root-only. The base overlay preserved those modes over the installed packages, which blocked the tablet session. Set public directories to 0755 and the tablet home subtree to 0700 before packaging. Preserve file modes and leave symlink targets unchanged. Assisted-by: LLM
Choose the shared codec from the current Orchard snapshot and keep coverage for its earlier module location. Explicitly skip the companion framing cases when the selected main snapshot has no Cascadia producer command. Codec import and execution errors still propagate. Assisted-by: LLM
A host tar consumer can exit at the archive end marker while the container still writes legal zero padding. With pipefail enabled, the producer's SIGPIPE then aborts an export whose files were already extracted. Use the portable --ignore-zeros option so extraction consumes the complete stream. Exercise the producer through a padded export and retain failure coverage for corrupted and truncated archives. Assisted-by: LLM

Arch Linux ARM publishes only a "latest" bootstrap, which it replaces, so a hash pin of it breaks at the next refresh. The pin names the 2026-08-05 build (still upstream's latest today), fetched from a copy in this repository's releases first, then from upstream while upstream still serves that build. Hash and signature checks are unchanged.
… index The 32-bit release now has the arm64 release's shape: the root as a block image (orchard.image.root_image), its logo, and the platform layers, loaders and install tools orchard's 32-bit index lists. Orchard is the device layer, so the distro builds no recovery, selects no board and carries no LwVM inputs or per-board platform layer. Dropped: the Cascadia recovery and its audit, selects-device and --device, the LwVM inputs, the native platform-layer producer, the recovery branch of the manifest, the assembly provenance checks (they refused modified orchard checkouts) and the per-file ELF/BPF checks of the root. Kept: the architecture choice, the ARMv7 builder (default builder image for armv7h), desktop/target.py, system/armv7, Omacalc, and the architecture checks of the desktop components, base and static tools.
A 32-bit release names each board's Cascadia loader ([cascadia.BOARD], from the index's loaders.cascadia), boots with recovery-autogo and has no Pongo, m1n1 or logo (orchard docs/distribution-contract.md, "32-bit roots"). From a published orchard build it takes platforms-armv7.toml with --architecture arm.

Selecting Orchard's
apple-armv7platform selects an Arch Linux ARMarmv7hroot and matching desktop components. ARM64 retains the current platform-index and block-image pipeline. ARMv7 uses the selected board's native layer and Cascadia recovery producers, with the static LwVM mapper and matching SSH helpers forwarded into both initrds.Native producer options are checked before cold-cache input resolution. Component keys include the selected build environment and wrapper. The release receipt measures source snapshots, component manifests and consumed files before assembly, checks them again afterward, and records the final root hash. Base and final release stamps remain distinct. Public layer tables contain only schema fields.
The generic installer and publisher retain their ARM64/Pongo policy. ARMv7 produces local archive, layer and recovery assets while public P105 installation remains gated. Source archives retain an exact producer-tree identity; Orchard's existing public install-manifest schema still requires a real Git commit and boolean modified. The qualified build path uses a clean Git snapshot.
Payload staging sets shared directories to mode 0755 and the tablet home subtree to 0700, preserving file modes and symlinks. This prevents a restrictive build umask from making the installed desktop inaccessible. Root export consumes tar's padding through EOF to prevent a host extractor from closing the container's output pipe early. Test fixtures resolve the Cascadia codec from the selected producer snapshot.

P105 is the owner's test board; Henrik or other owners cover other devices. Earlier unplugged desktop evidence belongs to the preserved development build. Proposed changelog text awaits owner approval.
