# Run govulncheck in BINARY mode against a freshly-built pad binary, NOT
# source mode (`govulncheck ./...`). Source mode builds an SSA call-graph
# over the entire dependency tree (BigQuery / OTel / gRPC / Google Cloud),
# which balloons to multiple GB of RAM and can lock up a memory-constrained
# host (BUG-2084). Binary mode reads the compiled binary's symbol table
# instead: a fraction of the memory, still call-graph-precise (it walks the
# binary's symbol graph), and it detects stdlib vulns from the Go version
# stamped in the binary. Because `pad` is a single binary containing the
# whole codebase (server + CLI), scanning it covers everything; not-called
# module vulns are naturally suppressed since their symbols aren't linked in.
# Mirrors the "Run govulncheck" step in CI's Go job — keep the two in sync.
#
# The build needs web/build to exist for the //go:embed directive. Locally
# `make web` / `make install` provides the real assets; the guard below
# drops a placeholder when it's absent (e.g. a fresh clone) so a standalone
# `make vuln` never fails on the embed. `go install foo@vX.Y.Z` is idempotent
# and rebuilds quickly when the pinned version is already cached.
#
# The scan binary is written to the repo root (real disk), NOT /tmp: some
# hosts mount /tmp as a small tmpfs (RAM-backed), where a large embedded
# binary can hit "no space left" and, worse, consume the very RAM we're
# trying not to exhaust (BUG-2084). It's removed on completion and
# .gitignore'd so an interrupted run can't leave a tracked artifact.

# Web pre-flight that mirrors CI's Web job beyond the build step:
# `npm audit` (production dependencies, high severity+) and svelte-check
# type checking. Depends on `web` so npm ci + build are already done.
# Separate target so a contributor iterating on the UI can run just the
# extra checks via `make web-check`.
web-check: web
	cd web && npm audit --audit-level=high --omit=dev && npm run check

# Run the web unit-test suite (vitest, non-watch). Mirrors the "Run web unit
# tests" step in CI's Web job. Kept separate from web-check so a contributor
# can run just the vitest suite via `make web-test`; `check` invokes both.
web-test:
	cd web && npm run test

# Pre-flight target that mirrors CI's Go and Web jobs. Run this before
# pushing — if it passes, the corresponding CI checks should pass too.
#
# Covers: golangci-lint suite (lint), Go test suite, govulncheck, npm ci,
# npm audit, web build, svelte-check, vitest unit tests. The race-detector +
# Postgres jobs only run on push to main (per .github/workflows/ci.yml) and
# are not included here; run `make test-pg` separately if you want them
# locally.
#
# `make install` stays lightweight (build + restart only) so the inner
# dev loop is fast; opt into `check` when you're ready to push.
