name: Periodic Evals
# The weekly coverage contract: EVERY periodic-tier paid test runs (EVALS_ALL,
# minus the reasoned excludes in test/helpers/periodic-exclude-data.ts), so
# tests can't rot invisibly — the class where the autoplan-dual-voice E2E was
# silently broken for months until a lucky local diff selected it. Engine:
# scripts/test-paid-shards.ts (the same runner local eval:bg:periodic uses):
# one planner manifest packed by recorded durations into as many ~7-minute
# executors as the work needs (one file, or a tightly packed group, per
# runner; overlays share one final slice), and a FAIL-CLOSED report — a slice
# whose artifact never landed is a failure, not an absence. The matrix size
# and job timeout come from the plan, so they cannot drift from the census.
# Full end-to-end flows run in the non-blocking marathon lane
# (evals-marathon.yml), never here. The gate-census
# job is the weekly EVALS_ALL backstop for the gate tier (PR lanes are
# diff-billed, so without it the full gate census might never execute
# anywhere); the hollow-shard guard (exit 0 + zero executed tests under
# EVALS_ALL fails) makes both lanes census-health checks, not just test runs.
# eval-bg (scripts/eval-bg.ts) finds its dispatch by the nonce in the run name.
