nx_race_telemetry.nx

nx_race_telemetry.nx -- SEED: substrate-native lap recorder. Replaces the bash bootstrap at bench/race_telemetry.sh for the hot path (lap recording). The bash script also handles patch/perspective/competition/tail/stats/clear -- those remain in bash until substrate-native CLI dispatch + tail/stats land. Per user directive 2026-05-15: "if we need to build our own shell and tools from the bits up lets do it" "i want nishi stack to do the work with you just initially mapping what needs to be done till it can be self sufficient" SEED scope (one responsibility, per cardinal 9): 1. Format one lap row matching the existing schema 2. Append to .race_telemetry.tsv via sys_openat_append + sys_write 3. Return bytes-written or -errno (no exceptions, no NULL) Existing bash schema (column-tab-separated): timestamp event_type bench_name lap_n duration_ms verdict thermal_c notes Substrate seed emits the same row layout but uses Unix-milliseconds for timestamp (sortable, monotonic in single-run; bash version uses ISO 8601). race_analysis.sh accepts either since it parses by column index, not by timestamp content. Sealed-enum verdict codes (caller passes one of these as i64): NX_RT_WIN = 0 NX_RT_TIE = 1 NX_RT_LOSE = 2 NX_RT_RECORD_ONLY = 3 NX_RT_UNDECIDED = 4 Out-of-range verdict falls back to RECORD_ONLY (defensive at boundary, per cardinal 12). license_tier: ORIGINAL genealogy_id: substrate-native -- no external derivation lineage_id: nx_race_telemetry_seed_q10
