# test               Run the test suite the way CI does (race + timeout).
# test-deadlock      Run the deadlock-detection pass CI also runs.
# fuzz               Actually fuzz. CI (and plain `go test`) only replays the
#                    committed seed corpus; this generates new inputs.
# cover              Per-package coverage (what CI uploads) + a function summary.
# cover-all          Cross-package coverage — the honest number. See below.
# sqlc-generate      Regenerate type-safe Go from sqlc.yaml (db/dbgen).
# sqlc-verify        Fail if the committed dbgen output is stale (used by CI).
# sqlc-install       Install the pinned sqlc version into $GOBIN.
# protocol-generate  Regenerate WS message-type constants (Go + TS) from docs/protocol-schema.json.
# protocol-verify    Fail if the committed protocol constants are stale (used by CI).
# otel-up            Start Jaeger + Prometheus for local tracing development.
# otel-down          Stop and remove the OTel dev containers.

# Every Fuzz* target, one at a time. `go test ./...` (and therefore CI) runs a
# Fuzz function against its committed seed corpus only — one pass per seed,
# zero generated inputs — so the harnesses find nothing new until this runs.
# Go fuzzes exactly one target per package per invocation, hence the loop.
#
# Deliberately local-only: a crasher is written to testdata/fuzz/<Target>/<hash>
# and that file IS a working reproducer. This repo is public, so a crasher stays
# uncommitted until its fix exists, then corpus entry and fix land together as
# one regression test.
#
# No make on Windows? The same loop, straight into Git Bash:
#   for pkg in $(go list ./...); do for fn in $(go test -list='^Fuzz' $pkg \
#     2>/dev/null | grep '^Fuzz'); do go test $pkg -run='^$' -fuzz="^$fn$" \
#     -fuzztime=30s || break 2; done; done

# Matches the CI invocation. Note that `go test ./... -coverprofile` instruments
