# Postures — the twelve fences

When a TSL8 arrives, the envoy needs to know **what kind of reader this wants**. Not a person (Tom, Charlotte, a senator's staffer) — a *posture*. A stance the cargo is braced to be read from.

A posture is a fence the reader will push against. The envoy, rendering the cargo, leans the document into that fence so the push lands somewhere honest instead of bouncing off a soft target.

## The twelve

1. **The skeptical engineer.** Will push on physics, tolerances, thermal budgets, mean time between failures. Wants numbers. Soft spots must be technical.
2. **The procurement mind.** Will push on cost-at-scale, supply chain fragility, vendor lock-in, BOM line items. Wants a BOM or a written-out excuse for not having one.
3. **The regulator.** Will push on who gets hurt, what precedent, what rule it breaks, what approval it needs. Wants named statutes, named agencies, named past rulings.
4. **The legislator's staffer.** Will push on who benefits politically, who's against it, what the ballot looks like, what the counter-ad looks like. Wants a coalition map and a kill-shot paragraph.
5. **The investor.** Will push on defensibility, market size, capital intensity, path to cash-flow. Wants a "why now" and a "why you."
6. **The founder-peer.** Will push on whether you've actually talked to customers, whether you're lying to yourself, whether the thing is a hobby. Wants the emotional honesty stripped of its varnish.
7. **The loving skeptic.** A friend who wants the idea to survive and will point at the thing you don't want to look at. Wants you to name the part you're avoiding.
8. **The historian.** Will point at the four previous attempts. Wants "why this won't repeat 1974" and "what's actually different."
9. **The domain expert.** Knows the field. Will push on things you got subtly wrong. Wants you to have cited real work, not a general impression.
10. **The first-time reader.** Knows nothing. Will get lost in jargon. Wants a plain-language summary at the top and an honest "you can stop reading after section 1 if you want."
11. **The one specific person.** A letter to a particular named recipient. Push-model is *what will this person personally want to ask me*, not a generic posture. The envoy reads the recipient's public context (with permission).
12. **The future self.** Sometimes the cargo is addressed to you, six months from now. Wants honesty, not a pitch. The envoy lets you be harsh.

## When each fits

| Cargo kind | Primary posture | Secondary |
|---|---|---|
| Hardware product | Skeptical engineer | Procurement mind |
| Software product | Founder-peer | First-time reader |
| Policy proposal | Legislator's staffer | Regulator |
| Theory / science | Domain expert | Historian |
| Personal letter | The one specific person | Loving skeptic |
| Protest case | Regulator | Historian |
| Comparative (paths for a client) | The one specific person | Skeptical engineer |
| Pre-read for a meeting | First-time reader | (the meeting's dominant posture) |
| Archived failure | Historian | Future self |

## How to use this

The envoy, rendering the cargo, says (not aloud, but in the shaping): *this cargo is braced for posture X. I will surface the things that posture X will push against. I will not hide them; I will put them where X will reach for them.*

If the sender has chosen wrong — is bracing against a skeptical engineer when the actual reader is a legislator's staffer — the envoy says so in the voice note: *Tom is bracing this as an engineering pitch; the reader is going to push on coalition, not BTU. Heads up.*

That is useful to both sides.
