/**
 * selftest.js — regression test for the Nomad scripts/ package (offline, never
 * touches any real deployment). Mirrors production hooks-core's selftest.js
 * pattern: pure-function unit tests + real spawned-subprocess end-to-end tests
 * against a mock team directory built fresh under the OS temp dir.
 *
 * Coverage:
 *   1. lib/config.js — findUp/resolveTeamRoot/resolveAgentHome/resolveLanguage/
 *      resolveSharedPath/firstExisting boundary cases
 *   2. lib/emit.js — three-platform payload shapes, resolveCwd priority chain,
 *      isDuplicateInvocation dedup guard
 *   3. session-start.js pure functions — parseTeamlogHead/parseKanbanHot
 *      (structured hit + degrade-to-raw miss)/parseInboxUnreadCount
 *   4. session-stop.js — decide() four branches + boundary values, newestMtimeMs
 *   5. lib/session-lock.js — acquire/release/check, conflict warning
 *   6. lib/file-lock.js — acquire/release, stale-lock self-heal
 *   7. append-log.js — end-to-end concurrency-safe insert against a mock file,
 *      --target resolution via team-config.json, anchor-miss hard error
 *   8. Three hook scripts spawned as real subprocesses (normal/empty/bad-JSON
 *      stdin), schema checks, double-fire dedup e2e
 *   9. (inside 8/9 blocks) double-fire dedup
 *  10. lib/frontmatter.js — block extraction/BOM/incomplete-block/column-zero
 *      scalar parsing (indented lines invisible by design)
 *  11. frontmatter-touch.js pure functions — computeNext decision matrix
 *      (replace/insert/idempotent/malformed-date/gate misses, CRLF+BOM
 *      preservation) + structural exclusion rules
 *  12. frontmatter-touch.js end-to-end — real subprocess against a mock
 *      NON-GIT team dir (the zip-extracted-team scenario): refresh + insert +
 *      mtime restore + second-run idempotence + exclusions + cap + outside-team
 *      silence. Also session-start.js charter-pointer section e2e.
 *
 * Results are written to a scratch dir under the OS temp dir; the printed path
 * is the source of truth — don't trust only the stdout summary line for a
 * failing run, open the JSON.
 *
 * Usage: node selftest.js
