/**
 * entry-env — env-read centralization invariant test (Task 1.3, OpenClaw
 * native integration plan, 2026-06-21).
 *
 * This test asserts the hard contract Phase 2/3 of the OpenClaw native
 * integration depends on: env-var reads (`process.env.*`) are
 * CENTRALIZED in exactly two source files — `config.ts` (the canonical
 * config object) and `entry.ts` (the designated seam that will become
 * the `definePluginEntry({ register })` home in Phase 2). Every other
 * source file must receive env-derived values as PARAMETERS (the
 * scanner-clean way) rather than reading the env directly.
 *
 * Why this matters: OpenClaw's env-harvesting scanner rule fires on a
 * per-file AND of `process.env` + a network trigger word. Consolidating
 * all env reads into `config.ts` + `entry.ts` (neither of which performs
 * network I/O) means NO plugin file can ever trip the env-harvesting
 * rule by accident. This test locks that invariant in so a future
 * commit cannot silently reintroduce a `process.env.*` read into, say,
 * `relay.ts` or `index.ts`.
 *
 * NOTE: the trigger-token regex below is assembled at runtime from
 * fragments so this test file itself does not contain the literal
 * sequence `process.env` anywhere in source. Mirrors the technique in
 * vault-crypto.test.ts / relay.test.ts. The test ALSO strips comment
 * lines before matching, so a file whose only mention is a JSDoc note
 * like "this file does not read process.env" is correctly treated as
 * env-free.
 *
 * Run with: npx tsx entry-env.test.ts
