Specialize repeater ACL session state, compact recent and flood records, stream Merkle proofs, and release cold OTA buffers safely. Preserve saved formats, stack sizes, table capacities, and OTA source limits. Account for lazy buffers when active and add compatibility, ARM alignment, allocation failure, and queued-response tests.
Validated six representative board/role builds, 1736 native test cases, sanitizer fixtures, and strict documentation. Document the preexisting Wio-E5 Mini flash overflow separately.
Keep Full sensors, UART2, adaptive OTA storage and the 8 KiB loop stack. Arbitrate shared SPI and OTA workspace ownership, move network waits into a worker, and use bounded queued TCP operations. Add reproducible test configs, RAM checks and regression coverage. Validated the Full build, UF2 layout and 29 sanitizer runtime scenarios.
Point both stable providers and runtime controls to the validated v1.17.1.9-halo-keymind-cascade-dev-88c85108 family. Record completed package validation while retaining hardware coverage limitations. Give all documentation source pages their exact hosted links and mount the telemetry form only in the browser. Verify current combined Full and nRF52 Full/Reduced catalog fixtures.
Keep the deployed SD target and layout, select qualified internal delta storage when no card is usable, and retain exact SD bootloader-update gates. Add storage, capability, transfer, recipe, and release-selection regression coverage.
Also preserve mandatory runtime packet logging in canonical XIAO images when verbose build debugging is disabled, fixing the four stopped release-matrix qualification failures.
Switch eight S3 board defaults and 78 remaining TinyUSB recipes to hardware Serial/JTAG while preserving UART and other platforms. Restore retained S3 PHY ownership after a TinyUSB OTA restart and prepare KISS queues before enabling the driver.
Add real recipe resolution, Companion/KISS transport sanitizer coverage, and RF lifecycle reset regressions to CI. Native tests pass 1765/1765; SDK, transport, recipe and USB watchdog checks pass. Board and role cross-compilation and physical OTA qualification continue.
DHCP can fill all DNS_MAX_SERVERS (3) slots, but only two were saved and restored, so a third server from one medium survived a switch to the other. link.dns now drops trailing empty slots to keep remote replies under 160 bytes.
Shows lwIP's live global DNS server list next to the DNS each medium's DHCP lease installed, so a node that is linked but failing to resolve can be diagnosed remotely.
Backport the pinned Arduino 2.0.17 HWCDC suffix and interrupt handling into a build-local source copy. Preserve unsent bytes, serialize ISR and producer rearm, and include FIFO, suffix and active writers in transport cleanup proofs without changing the loop stack allocation.
Validate zero and short writes, producer races, quarantine and stale cleanup with sanitizer-backed native tests and negative controls. Keep other frameworks and USB modes on their existing drivers; update the watchdog file mock for the existing buffer API.
A switch can land on an older build: e.g. prod cannot read dev's /mqtt.json,
and prod's M7 image has no Ethernet. Each image carries an ota-compat tag
(state generation + transports). A switch is flashed without rebooting, the
new image's tag is read (bounded by its length), and boot is pointed back at
the running image unless the target keeps this node's state and transports.
CI now requires the tag in every published binary.
Every observer build now carries both channel URLs, so checking for a URL's
presence or absence can no longer tell prod from beta (and the old checks would
reject every build). Read the ota-base-* tags from every .bin in out/ instead
of a single ELF, with URLs shared by build.sh and both workflows.
Use a bounded uzlib-derived block encoder with the existing strict tinf decoder, qualify infrastructure roles, budget temporary RAM, and cache running-image metadata. Add self-serve CLI and policy, USB host-loss sleep grace, hardware test harnesses, regression tests, and CI coverage.
Keep Companion and Terminal Chat profiles unchanged; retain full-sensor and reduced-sensor OTA builds. Add compact crypto and OTA names, qualified display asset compression, font license packaging, and scope regression tests.
