* ci(test): shard the native test suite across a matrix Replace the single sequential runner with a matrix populated by bin/test-shards.py from the test/ tree: areas over --max-suites are split, smaller ones packed, and a --max-shards budget bounds the fan-out. A collector job merges the per-shard JUnit reports, checks the union against the canonical suite set, and states the verdict. Native PlatformIO Tests remains as the single required check over the matrix. Drop the --without-testing warm build. PlatformIO links every native test program to the same $BUILD_DIR/$PROGNAME, so the area run relinked each suite regardless. ccache carries the shared src objects between shards instead; one shard is flagged cache_writer so a single entry is saved. The coverage-event-policy and coverage-channel-table envs and the attribution canary move into their own matrix rows and job. Harden the new paths: bound the matrix row count so a branch cannot size the fan-out, reject multi-line or empty $GITHUB_OUTPUT values, fail the whole-run attribution gate on an empty expected set, upload exact report and tracefile names instead of globs, and pass the repo path to bin/lib/shuffle.sh as an argument rather than into bash -c source text. 12 shards, largest 9 suites. * ci(test): minimal test toolchain, cap shard runtime, fix pack overflow Add .github/actions/setup-native-test, used by the shard and canary jobs in place of setup-native. It drops the redundant second checkout, both submodules (src/mesh/generated is tracked, meshtestic is the hardware harness), cppcheck, and the adafruit-nrfutil, poetry and meshtastic pip installs, and folds in ccache and lcov. setup-base and setup-native are unchanged, so the firmware matrix and every other consumer keep theirs. Cap the shard job at 30 minutes. A lost runner held one for 48 of the 360 GitHub allows by default, and there are twelve of them. pack() could exceed --max-suites: ceil(total / cap) is a lower bound and whole areas do not divide, so three areas of 6 at cap 10 put 12 in one of two bins. Grow the bin count until every bin fits. Validate the fixed-env test_filter tokens against SUITE_RE. PlatformIO accepts globs there, and those tokens reach the same word-split and the same attribution gate as discovered names. Split with read -ra so a token cannot glob against the workspace either. Report the suite count rather than the length of the -f argument array, which counted every name twice. Trim comments to the one or two lines AGENTS.md asks for. * ci(test): quote the $GITHUB_OUTPUT redirects Applied to all five, including the three that predate this branch, so the file is consistent rather than half-converted.
