S4 (a1): the media engine — VOICE templates, /desk, Ghost drafts
4a VOICE v1.1 committed (board start); lint is EXECUTABLE — banned list + no-exclamation law enforced in the engine (throws in test, drops in prod) and locked by tests. Curly-apostrophe variants covered. 4b mediaEngine: deterministic templates (MORNING WIRE, SIGNAL, STREAK WATCH, THE SETTLE, RECEIPTS, ARCHETYPE WATCH, LINE DISPATCH) filled ONLY from snapshot/ledger/streaks JSON. Record percentages never render under n>=20 (counts + 'Record building' below). Stark layer = curated committed library (content/stark-lines.json), day-rotated selection — selected, never generated. 4c /desk (founder-only: requireAuth + DESK_OWNERS email allowlist, deny-by-default): all formats as text + <=280-char pre-segmented tweets with per-tweet copy buttons + char counts, wire/numbers-only variants, DATA BRIEF block (structured day numbers) with copy-for-claude.ai. ntfy ping after the day's first snapshot: 'Desk pack ready'. 4d ghostPublisher: DRAFTS ONLY (status:'draft' test-locked), env-gated no-op, HS256 JWT via node crypto (zero new deps). POST /api/internal/ghost/drafts saves slate preview + settle drafts. Nothing anywhere auto-posts. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
