The old node must already have working MeshCore LoRa mOTA, a valid EndF,
and the exact target ID in `manifest.json`. A stock image without that updater
cannot take this route. The bridge checks the old receiver before changing the
table and refuses if its image or target does not match.
If this bridge is accidentally installed on a node that already has the
expanded table, it verifies the other OTA slot's target, EndF image hash and
bootability, then returns to that firmware without changing the table. It
refuses a second migration bridge or an invalid other image; Wi-Fi recovery
remains available if no safe LoRa image exists and identity restoration has
completed. A failed identity restore disables firmware upload. Do not
deliberately install the bridge on an already-expanded node; use the Full image
directly.
{slot_instructions}The Full image has {full_mota_blocks} blocks and needs a seeder with at least
{full_mota_blocks * 4} bytes of proof scratch. Older 4 KiB-scratch seeders cannot
serve more than 1024 blocks. Verify that a capable seeder lists the Full image
before installing the bridge.
The resized SPIFFS may reset saved radio settings. Before stage one, know
the old receiver's compiled default radio profile and arrange a seeder on
that profile for stage two; a remote node that cannot hear the seeder cannot
finish its LoRa migration.
1. Make `lora-bridge.mota` available from a compatible mOTA seeder. On the old
node use `ota ls`, `ota pull <id> flash`, then `ota install` after the
complete download. A manual install handles an equal-version bridge.
2. Keep power stable. The bridge expands the table; {handoff}. It then reboots
into the preserved old LoRa receiver in the opposite slot.
3. Serve `full-application.mota`; again use `ota ls`, `ota pull <id> flash`,
then `ota install`. The old receiver now sees the expanded inactive slot.
A full-image LoRa transfer can take considerable time.
`full-application.bin` and `full-application.mota` are the same exact-target
Full image. `target-partitions.bin` is included for verification only;
do not upload it to the browser. Neither bridge is a USB merged image.

Source: `{source}`; firmware version: `{version}`. This package is only for the
physical board/role represented by `{spec['target']}` with
{spec['flash_bytes'] // 1048576} MiB flash. A legacy Wi-Fi-updatable observer or
bridge variant on the same hardware may migrate to this canonical Full target;
its previous feature settings are not preserved. The LoRa route, where present,
requires the old image's exact target ID.
The current partition table must have stable NVS at 0x9000, OTA metadata at
0xE000, two OTA apps, and SPIFFS with `/identity/_main.id`.
The bridge checks the live layout and refuses unsupported boards. It stages
the 96-byte public/private identity in unchanged NVS, preserves a bootable old
receiver, and changes the partition table. On 8/16 MiB LoRa and Wi-Fi routes
the bridge restores and verifies the identity in expanded SPIFFS; on the
4 MiB LoRa route the new Full firmware does so at first boot. No full-chip
erase or USB connection is used.
The table sector and inactive app sectors are erased as part of migration.
SPIFFS may be reformatted; other SPIFFS settings can be recreated.
The stock bootloader has no atomic backup partition table: power loss during
the table-sector erase/write can still require cable recovery. Do not use this

example of the same board first.
