Suggested reviewers: Merge Risk: 🟡 Moderate · up to A temporary storage failure can silently leave application data unsaved even after storage becomes writable again. Preserve dirty state until saving succeeds before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The inspected display interfaces remain within the local application, and packaging defaults to requesting no sandbox permissions. Persistence inherits failure-handling limitations from the existing desktop target. No introduced security exploit was established, but storage ownership, concurrent execution, and platform enforcement remain insufficiently verified for a minimal-risk assessment.

Review comments at @targets/raspberry-pi-os/main/rpios_main.cpp:
- Around line 513-515: Update the Sailfish preparation script to include
rpios_storage_bridge.cpp in GEA_CXX_SOURCES, and remove the GEA_SAILFISH_OS
guards around rpios_runtime_storage_load() and rpios_runtime_storage_flush() in
rpios_main.cpp so runtime localStorage persists across launches.
Review comments at @targets/sailfish-os/prepare.mjs:
- Line 81: Before writing the RPM spec in prepare, convert npm prerelease
versions to an RPM-compatible form, such as replacing the prerelease hyphen with
a tilde; alternatively, reject them during preparation with a clear error. Apply
the validation or conversion to the version used for the spec’s Version field.

- Line 85: Validate the values used for the RPM Summary and License fields
before generating the spec in the writeFileSync block: reject carriage returns,
newlines, and RPM macro markers. Interpolate the validated values instead of
app.name and meta.license directly, preserving their existing fallback behavior.

- Line 91: Update ensure_window() to check g_framebuffer immediately after
ensure_canvas() and return if allocation failed. Perform this check before SDL
initialization and before setting attempted, so Display::init() reports failure
and a later call can retry.

into window-pixel coordinates, then map them through SDL_RenderWindowToLogical
using the active renderer before queuing the touch event. Clamp the resulting
logical coordinates to the canvas bounds.

Also updated the PR description to reflect the independent Sailfish platform sources. Verified that package.json and the lockfile already agree on the Node.js requirement (>=20.19), so no change was needed there. |

Summary
Add a Sailfish OS target that packages Gea JSX/CSS applications as RPMs. The target owns its Sailfish-specific SDL2 display, input, storage, and network sources, with fullscreen sizing and startup settings. Raspberry Pi OS sources are unchanged from the base branch.
Provide Linux Bash and Windows PowerShell entry points. Both run host-side Gea code generation, stage a portable CMake/RPM project, then build it with
sfdk. The first supported target is Sailfish OS 5.1.0.11i486.Validation
i486.--prepare-onlypath in MSYS2. A fullsfdk buildon a native Linux host has not been run yet.Scope
CLI integration (
gea build --target sailfish) and ARM device packages are future work.Summary by CodeRabbit
