Your task: outline a 3-act factual documentary anchored to a REAL, VERIFIED event on {today_month_day} for a university-level ESL audience (CEFR B2/C1). CATEGORY: {category} {cat_instruction} CULTURAL FOCUS: {focus_instruction} ════════════════════════════════════════════════════════ HISTORICAL ANCHOR: "ON THIS DAY" ({today_month_day}) ════════════════════════════════════════════════════════ You MUST anchor this documentary to a real, verified historical event that occurred on {today_month_day}. Include "historical_anchor": {{"event":"...","year":"...","description":"..."}} If no verified event exists on this exact date, choose the closest within ±3 days and note the actual date in the description field. ════════════════════════════════════════════════════════ ══════════════════════════════════════════════════════════════════ HISTORICAL INTEGRITY FIREWALL — THESE RULES OVERRIDE EVERYTHING ══════════════════════════════════════════════════════════════════ RULE 1 — DOCUMENTED FIGURES ONLY: The "characters" array MUST contain ONLY real, named historical figures documented in primary sources or peer-reviewed scholarship. For each character, you MUST specify WHICH archive or source documents their role in this specific event (the "primary_source" field). BANNED: "a court scribe", "a garrison soldier", "a local merchant", "a palace attendant", "an anonymous witness", or ANY unnamed or unverified generic figure invented to add colour. If the historical record is silent on individual participants, the documentary narrates the DOCUMENTED ACTIONS of institutions, armies, or governments — not invented individual observers. RULE 2 — SENSORY CUES MUST CITE MATERIAL EVIDENCE: The "sensory_cue" field in each chapter must describe a material condition documented by archaeology, primary accounts, or climate records — NOT a mood invented for cinematic effect. CORRECT: "The smell of pine resin from the wooden siege engines documented in the Chronicle of Ibn al-Athir." WRONG: "The tense silence before the battle began." WRONG: "The smell of damp earth and freshly cut grass." RULE 3 — ERA-ACCURATE OBJECTS ONLY (Anachronism Guard): The "ambiance" field must NOT reference objects that did not exist in the documented era. Verify every object before including it. BANNED BY ERA: Before 1440 CE → no printing press / movable type Before 1590 CE → no compound microscope Before 1800 CE → no photographs / railways / telegraph Before 1836 CE → no repeating rifle / revolver Before 1884 CE → no Maxim gun / machine gun Before 1885 CE → no gasoline automobile Before 1903 CE → no aircraft Before 1936 CE → no Olympic torch relay (invented Berlin 1936) Before 1945 CE → no nuclear weapons in use If uncertain whether an object existed in the era — OMIT IT. RULE 4 — CHAPTER ENDPOINT CONTRACTS: Chapter 1's FINAL action_point MUST be an unresolved documented moment: a decision not yet recorded, a battle not yet joined, a treaty not yet signed. This seeds the Narrator's cliffhanger. Label it explicitly: "10. [UNRESOLVED MOMENT — cliffhanger seed]" Chapter 2's FINAL action_point MUST be the exact documented moment the outcome became irreversible — stated as bare fact, no commentary. Label it: "10. [TIDE-TURNING FACT — bare, no commentary]" Chapter 3's FINAL action_point MUST be a verifiable statement of enduring historical fact — measurable, declarative, final. Label it: "10. [ENDURING FACT — declarative, verifiable, final]" RULE 5 — VERIFICATION STEP (MANDATORY BEFORE FINALISING): Cross-reference ALL names, dates, casualty figures, geographic locations, and material objects. If any detail is contested, default to the most widely accepted scholarly consensus. RULE 6 — NO SPECULATIVE CROSS-CIVILISATION LINKS: The story_premise and historical_context MUST connect ONLY events that share a DOCUMENTED, NAMED primary source link. BANNED: connecting two civilisations through inference, trade speculation, or indirect causation not documented in a named archive or peer-reviewed study. EXAMPLES OF BANNED LINKS: ✗ "The Mapuche silver trade influenced Swedish military expansion" ✗ "Cossack governance inspired New England colonial structure" IF NO DOCUMENTED LINK EXISTS between two civilisations: Narrate ONE civilisation deeply and accurately. A focused honest documentary is superior to a speculative one. RULE 7 — BANNED WORDS IN ALL TEXT FIELDS: The following words are BANNED in story_premise, historical_context_en, learning_goal_en, summary, and ALL text fields you generate. Using any banned word is an automatic failure. BANNED NOUNS (cliché and metaphorical): legacy, testament, tapestry, watershed, crossroads, turning point, crucible, cornerstone, milestone, beacon, torch, flame, canvas, mosaic, fabric, echo, shadow, shroud, backdrop, forge, dawn (as era) BANNED ADJECTIVES (empty intensifiers): pivotal, seminal, momentous, fateful, legendary, epic, heroic, iconic, groundbreaking, haunting, transformative, unprecedented (unless verified as the literal first documented instance), strikingly, remarkably, profoundly (as empty filler) BANNED PHRASES: "changed history", "make history", "pages of history", "course of history", "the rest is history", "left an indelible mark", "shaped the world we know today", "a new chapter began", "would never be the same", "stood at the crossroads", "the die was cast", "rippled through the centuries", "power vacuum" CORRECT story_premise: "This documentary examines the Battle of Narva (1581) and its documented consequences for Swedish territorial control in Livonia, as recorded in the Swedish National Archives (Riksarkivet)." WRONG story_premise: "This documentary examines a pivotal moment that served as a testament to Sweden's legendary military prowess." ══════════════════════════════════════════════════════════════════ 3-ACT STRUCTURE (MANDATORY): -- Chapter 1 -- THE SETUP / THE SHOCK: Establish verified historical context and documented stakes. Introduce the inciting event with full scholarly grounding. -- Chapter 2 -- MECHANICS & CONSEQUENCE: Examine the precise documented mechanisms of how events unfolded: troop numbers from records, logistics from supply archives, diplomatic exchanges from authenticated correspondence, technological factors from contemporary accounts. -- Chapter 3 -- THE VERIFIED AFTERMATH (DEFINITIVE CONCLUSION): Articulate documented permanent change: territorial, political, cultural. Cite measurable consequences: square kilometres, treaty article numbers, population figures, casualty counts from primary records.

Faces: rendered as thick impasto — unresolved, impressionistic, never detailed. ERA C — 20TH CENTURY ONWARDS (1900 CE–present): STYLE ANCHOR — begin every prompt with EXACTLY these words: "gritty 35mm black-and-white archival photograph, Leica street photography, high contrast, heavy film grain, halation on light sources, backlit silhouettes against overexposed sky, silhouette, blurred features, heavy shadows, atmospheric lighting, no clear faces" COMPOSITION: subjects backlit or side-lit — faces burned into shadow or silhouette. Prefer: silhouettes against smoke, rubble, crowds, or overexposed industrial sky. ════════════════════════════════════════════════════════ STEP 3 — UNIVERSAL COMPOSITION RULES (ALL ERAS) ════════════════════════════════════════════════════════ MANDATORY — every prompt MUST include these five terms verbatim: silhouette, blurred features, heavy shadows, atmospheric lighting, no clear faces COMPOSITION HIERARCHY (use the highest applicable tier): TIER 1 — OBJECT CLOSE-UPS (preferred): Hands with era-accurate historically significant objects: gloved hand pressing wax seal onto a treaty (pre-1900 CE), ink-stained fingers tracing a siege map (any era), scholar's calloused hand over an open manuscript, sword hilt gripped in gauntleted fist (pre-firearms era), quill pen mid-signature on a document (pre-1850 CE), compass rose on a nautical chart (post-1300 CE), astrolabe in brass (post-800 CE). TIER 2 — BACK-VIEW OR SILHOUETTE FIGURES: general seen from behind surveying a battlefield (no face visible), robed figures in a torch-lit corridor seen from the side, soldiers silhouetted against burning horizon, lone rider on ridge seen from behind against overcast sky. TIER 3 — WIDE-ANGLE OR OVERHEAD COMPOSITIONS: grand architecture dwarfing tiny human figures, aerial view of siege fortification or harbour under sail, vast steppe landscape with distant mounted column. FACE RULE: A face may appear ONLY as an indistinct element lost in a crowd where individual features are completely unresolvable. A face may NEVER be the subject of the composition. ════════════════════════════════════════════════════════ STEP 4 — OUTPUT FORMAT RULES ════════════════════════════════════════════════════════ cinematic_image_prompt: — Comma-separated KEYWORDS ONLY. Fifteen to twenty words maximum. — MUST begin with the ERA-SPECIFIC style anchor (verbatim from Step 2). — MUST include all five mandatory keywords from Step 3. — ONLY era-verified objects (passed the Anachronism Guard in Step 1). — NO full sentences. NO verbs. NO emotional adjectives. BANNED KEYWORDS (absolute — never appear in any prompt): haunting, solemn, powerful, dramatic, tragic, defiant, hopeful, beautiful, majestic, glorious, heroic, impressive, stunning, emotional, moving, iconic, pivotal, epic, legendary, timeless, eternal, destiny, legacy, freedom, oppression, sacrifice, and any full sentence or verb phrase. CORRECT example (Era B — 19th century treaty signing): "heavy impasto oil painting, thick palette knife brushstrokes, Flemish master technique, blurry unresolved facial features, focus on costume and material culture, muted earth tones, aged varnish cracks, silhouette, blurred features, heavy shadows, atmospheric lighting, no clear faces, ink-stained gloved hand, quill pen on treaty parchment, red sealing wax, candlelit interior" WRONG example: "A powerful and dramatic scene of heroic figures at a pivotal moment." ════════════════════════════════════════════════════════ Generate: 1. cinematic_image_prompt — apply all four steps above in order. 2. audio_environment object: - primary_ambience: one of [desert_wind, battlefield, monastery, ocean_waves, forest, cave, city_market, palace, thunderstorm, night_camp, forge, harbour, library, steppe] - intensity: "low" | "medium" | "high" - dynamic_cues: one sentence — the dominant PHYSICAL sound at the chapter climax. Name the specific MATERIAL producing the sound. CORRECT: "Iron cannon wheel rims grinding on cobblestone as the artillery column advances through the city gate." WRONG: "The sounds of battle fill the air." [no material named — BANNED] - audio_prompt: two to three sentence foley-script. Name specific instruments, materials, surfaces, and physical actions. No abstract mood words. No emotional descriptors. CORRECT: "Hammer strikes on cold chisel against Pentelic marble, workers shouting measurements in Greek, wooden scaffolding poles grinding against each other under load. Beneath it, the constant scrape of iron-wheeled carts on the stone ramp carrying marble blocks." WRONG: "Atmospheric sounds create a sense of ancient grandeur."
