+/**
+ * reseed-rini-demo-freshness.ts — freshness pass for the Rini University
+ * Baseball demo team (seeded by scripts/seed-rini-baseball-demo.ts).
+ *
+ * Problem: scripts/seed-rini-baseball-demo.ts computes every date relative
+ * to "now" AT THE TIME IT WAS LAST RUN. Real calendar time keeps moving, so
+ * every re-run of a demo (screenshots, a live walkthrough) shows the
+ * upcoming game/practice/meeting sliding further into the past, readiness
+ * check-ins going stale, and several feature surfaces (development plans,
+ * documents, messaging) that the base seed never populated at all.
+ *
+ * This script is a companion, NOT a replacement: it (a) freshens dates on
+ * rows the base seed already owns, using the SAME deterministic ids so it
+ * UPDATEs in place (never deletes), and (b) adds a few demo-only surfaces
+ * the base seed doesn't cover, under its own deterministic id namespace so
+ * re-running never duplicates rows.
+ *
+ *   1. Re-dates the team's anchor events (practice/game/meeting) and the
+ *      two "next" scheduled games to be relative to TODAY, so "this week"
+ *      always shows a future game + practice + meeting.
+ *   2. Seeds 2 development plans (4 goals each; one plan partially
+ *      completed) so the dev-plan detail UI (goal checkboxes / progress
+ *      ring) has real content to demo, for both the player-facing
+ *      "My Development" (active plan) and the coach-facing dev-plans list
+ *      + detail views.
+ *   3. Seeds 4 team documents (playbook, schedule, travel policy,
+ *      conditioning manual) as real `baseball_documents` +
+ *      `baseball_document_versions` rows, backed by tiny placeholder
+ *      `.txt` files uploaded through the SAME storage bucket + path
+ *      pattern the app's own upload action uses (`documents` bucket,
+ *      `baseball-documents/<teamId>/<file>.txt`) — not fake metadata
+ *      pointing at nothing.
+ *   4. Seeds 1 coach -> player conversation with 4 messages (a natural
+ *      back-and-forth, most recent unread) so Messages has content.
+ *   5. Re-dates the "recent" lift sessions, program assignments, and
+ *      readiness check-ins (both the live `helm_lifting_*` tables AND the
+ *      legacy `baseball_readiness_checkins` table a couple of surfaces
+ *      still read) so the readiness/"today's lift" panels read as current.
+ *
+ * Idempotency:
+ *   - (1) and (5) are partial-column UPSERTs (`onConflict: 'id'`) against
+ *     ids the base seed already created — Postgres `ON CONFLICT DO UPDATE
+ *     SET <listed columns>` never touches columns this script doesn't
+ *     list, so unrelated columns (roster, box scores, etc.) are untouched.
+ *     No destructive delete-then-insert anywhere.
+ *   - (2)-(4) are NEW rows this script owns, keyed by deterministic ids
+ *     derived from a DEDICATED namespace (`baseball-demo-reseed-v1`,
+ *     see `detId2` below) — that namespace *is* the stable ownership
+ *     marker: every id this script mints is reproducible from
+ *     (namespace, logical key), so re-running just upserts the same rows
+ *     again. Nothing is ever deleted, so there's no risk of a marker being
+ *     needed to find rows to clean up — but the namespace is documented
+ *     here precisely so a future cleanup pass could find them by prefix
+ *     if ever needed.
+ *
+ * Requires the BASE seed to have already run — this only freshens dates /
+ * adds a few demo-only surfaces on top of an existing team/roster/coach.
+ *
+ * Run:
+ *   DOTENV_CONFIG_PATH=.env.local npx tsx -r dotenv/config scripts/reseed-rini-demo-freshness.ts          # dry run
+ *   DOTENV_CONFIG_PATH=.env.local npx tsx -r dotenv/config scripts/reseed-rini-demo-freshness.ts --confirm # write
+ *
+ * Requires env: NEXT_PUBLIC_SUPABASE_URL, SUPABASE_SERVICE_ROLE_KEY.
+ * Golf is NEVER touched. Only rows belonging to Rini University Baseball
+ * (team + org ids below) are written.
