custom_sdkconfig makes pioarduino regenerate the ESP-IDF libraries:
asymmetric TLS buffers (16 KB in, 4 KB out) and dynamic buffers that
free handshake-only data once connected. The rebuild also follows the
board: no PSRAM, 8 MB flash. The project now carries the partition
table the hybrid build needs (identical to the framework's: the app
slots must not move under updates over the air). Generated files are
ignored.
Debug Build, GNSS on, IRC on TLS: 78 KB free and a 59 KB low (M2 began
at 31 KB and 12.6 KB; the floor is 40 KB). The full stress set passes
on it: refused installs over Wi-Fi and from SD, put/get, screenshot,
core dump decode, Probation; under all of it at once, the low is 46 KB.

- scripts/ota_keygen.sh: ECDSA P-256 key pair; the private key goes to
~/.config/roro9stack/ (0600), the public key to keys/ and
src/platform/ota_public_key.h; .gitignore refuses *key.pem
- scripts/make_ota.py: wraps firmware.bin into a signed .ota (openssl)
- scripts/ota_push.py: sends it over TCP 3232, prints the device's answer
- scripts/flash.sh --ota <host>: build, sign, push
Checked: a generated .ota has the documented layout and its signature
verifies with openssl against the committed public key.
