The real Arduino.h includes stdlib.h, so ConfigSerializer.cpp reaches atoi,
atol and atof through it and compiles on device. The mock supplied only
cstdint, cmath and Stream.h, leaving those undeclared — and since the native
env compiles ConfigSerializer.cpp into every suite via build_src_filter, all
21 suites errored rather than just its own.
Fixing the mock keeps src/ identical to upstream and covers any other source
relying on the same transitive include.
pio test -e native: 297 test cases, 297 succeeded.
Switch ESP32-S3 KISS modem environments to HWCDC and move outbound KISS writes to a non-blocking queued frame path so loop() and TX completion keep progressing when the host reads slowly. Add native backpressure regression tests and correct the native_kiss_modem test filter so this suite runs directly with pio test.
hasSeen() was simultaneously a predicate and a mutator — it inserted the
packet hash on every miss, making five call sites that only wanted to mark
a packet as sent call it with the return value discarded.
Split into:
- wasSeen() — pure predicate, no side effects
- markSeen() — explicit insert
All query sites now call markSeen() immediately after wasSeen() returns
false, preserving identical runtime behaviour. The five mark-only send
sites (sendFlood, sendDirect, sendZeroHop x2) now call markSeen directly.
Also fixes three bridge sites (BridgeBase, ESPNowBridge, RS232Bridge)
that had the same query+implicit-insert pattern.
Tests: add test/test_mesh_tables/ covering wasSeen purity, markSeen,
dup stats, and clear. Update SHA256 mock to produce deterministic output
(previously finalize() was a no-op). Add Packet.cpp to native build filter.
