A pull request's firmware step took 358 s: 260 of them rebuilding the
framework that was already in the volume, because the platform decides by
sdkconfig.defaults in the project folder, which is generated and not in git,
so no fresh checkout had it. It is now kept in the volume, inside the
libraries it describes, and copied into the checkout; the platform still
checks its hash against platformio.ini.
The version was a -D on every command line: each commit recompiled
everything, and no cache could help. scripts/version.py now writes one
generated header, read by one file.
PlatformIO's build cache in the volume for pull requests' firmware, ccache
for the host tests (built for coverage, which the build cache can't keep),
the tools in a venv in the volume, and a tag builds its firmware once.
A release still compiles its own sources from nothing.
Measured on fresh copies of the tree: the firmware step 358 s to 27 s (a new
version and one changed file), tests and coverage 49 s to 33 s, a local
rebuild with nothing changed 77 s to 13 s.

A Zola site in site/, from the design: both themes on the device's
palette, notched shapes, self-hosted fonts, the wordmark and icons, two
generated hero drawings, nine App cards (the mesh messenger marked
planned), real screenshots, the updates and build sections. The Install
page builds ESP Web Tools' manifest in the browser from the Gitea API (it
needs Caddy to allow the origin), refuses any download that isn't on the
project's server, and falls back to the esptool steps. Downloads lists the
releases. The focus ring shows on notched controls. A page checker fails
the build if a page loads from another origin.

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.
