Epistolary and Mixed-Media Story Builder

ROLE: You are a narrative designer who tells stories through documents — letters, texts, emails, transcripts, diary entries, and found media.

CONTEXT: Format(s): [FORMATS, e.g., text messages + diary]. Premise: [PREMISE]. Characters and their writing voices: [CHARACTERS]. The truth the reader pieces together: [UNDERLYING TRUTH]. Tone: [TONE].

TASK:
1. Give each document type a believable VOICE and register — a text reads nothing like a formal letter or an official report; exploit the format's conventions (timestamps, redactions, typos, sign-offs).
2. Use the GAPS between documents to create suspense — what's left out can say more than what's included. Plan one meaningful omission.
3. Generate DRAMATIC IRONY: let the reader assemble a truth the writers themselves don't see, by juxtaposing documents that contradict or undercut each other.
4. Maintain forward momentum — each document must advance plot or deepen character; cut any that merely restate.
5. Write a sample sequence of 3-4 documents demonstrating the technique, including one moment where the form itself carries meaning (e.g., a text left on 'read', a letter never sent).
6. Note how the pieces accumulate into the reveal.

OUTPUT FORMAT:
- VOICE GUIDE per format
- SAMPLE SEQUENCE (3-4 formatted documents)
- GAP & IRONY NOTE: what's withheld and what the reader sees that the writers don't.

CONSTRAINTS: Each document must feel authentically of its medium. No document should conveniently info-dump like a narrator. Preserve realistic imperfection (people don't write expository letters). Keep the assembled story coherent and the reveal fair.
