asn1/ Three tests assert exact bytes - CamEncodeGoldenTest, DenmAirReceiveTest and SpatemUperCodecTest - and their expected values came from asn1tools compiled against ETSI modules that existed only as an untracked working copy on one machine. A golden-byte fixture nobody else can regenerate is a fixture nobody can safely touch, so the modules are now in the repo. Only the seven .asn files those tests need are copied, 576 KB of a 4.2 MB checkout; the upstream Rust parser is not used by this project at all. Verified sufficient in isolation: copied into an empty directory, all three specs compile and reproduce the committed golden CAM bytes byte-identically. Source is consider it GmbH's C-ITS-Parser (github.com/consider-it/C-ITS-Parser) at f457426, MIT licensed - LICENSE is retained alongside as that requires. The schemas themselves are ETSI's standard definitions; upstream's contribution is assembling them into a compilable set. asn1/README.md records the provenance, which module pairs with which message, and the rule that matters: never regenerate a golden fixture from this project's own encoder, because sharing a mistake between encoder and decoder is exactly the failure these files exist to catch. Doc references in the codecs and tests now point at asn1/ instead of the untracked checkout, and C-ITS-Parser/ is gitignored so the working copy beside the project is never picked up. Untracked local state - .idea/deploymentTargetSelector.xml rewrites itself on every deploy, so it has been showing as modified in essentially every commit. Along with deviceManager.xml, appInsightsSettings.xml and studiobot.xml it is per-machine state, not project configuration. - obu-firmware/sdkconfig.old is ESP-IDF build output - it is the previous sdkconfig, rewritten on every build. sdkconfig.defaults remains tracked, since that is the configuration actually chosen. All five stay on disk; only the tracking is removed. Also ignores .claude/settings.local.json, which is per-machine, while leaving the skills beside it committable as project knowledge.
