Replace length-derived strncpy calls with memcpy and explicit termination. Ensure parseStr also terminates fields that end without a delimiter, and extend the bounds regression to cover truncation, empty fields, and one-byte destinations.

Create up to 10,000 distinct long filenames with exclusive creation, drain startup GPS command replies before writing, and update CI and installation guidance for the Adafruit fork.

Use shared PROGMEM tables with flash-aware lookup and copying. Preserve the source IDs, sentence IDs and matching order while saving 110 bytes of RAM in the Uno SD logger.

Prevent setup from being inlined into main so SD initialization temporaries are released before loop runs. Uno disassembly confirms main no longer retains a 129-byte local frame and two saved registers.

Add an F()-compatible sendCommand overload and keep the SD logger command strings in flash. This saves 82 bytes of RAM on Uno.

Remove the unreferenced 100-byte private buffer. The Uno SD logger now uses 1865 bytes of static RAM, down from 1965 bytes. All 20 examples compile.

Keep only the eight F() wrappers in shield_sdlog so RAM improvements can be reviewed one at a time. Defer the other memory changes. This step saves 90 bytes on Uno, leaving 83 bytes; compilation passes but runtime SD logging still needs more RAM.

Keep lookup tables, sentence IDs, logger messages and commands in flash; remove the unused SPI buffer. Keep setup separate so SD initialization does not retain its stack frame during logging.
