The Triangle Pass

An introduction lives at the entry layer, where the audience has not yet agreed to spend their attention. That layer has its own discipline, and it is mostly restraint. The Triangle Pass is the reusable production step for getting it right.

The pass runs the Triangle of Yaps (canon/meta/triangle-of-yaps.md) in the one place it is most tempted to overreach: the opening. It enforces the resolution to the engagement-versus-proof tension — the introduction is the door, the proof is the house, and the next-step corner is the threshold between them. You win enough attention and trust to make someone step through, then you point them at where the evidence actually lives. You do not drag the proof out onto the doorstep.

The five moves are: (1) name the one thought, (2) open on the audience's stake, not the system, (3) make it land once with a single illustration, (4) point the door at real proof, (5) stop before you prove. Run them in order, then check the result against the pass checklist before you publish or record. The pass applies at every scale, because introductions nest: a weekly overview opens the door to an essay, an essay opens the door to a section, a section opens the door to its evidence.

Most presentation advice assumes the audience is already listening. The entry layer cannot assume that. A homepage visitor, a podcast listener in the first ten seconds, a reader scanning the opening paragraph — none of them have committed. The job of an introduction is narrow and specific: convert a non-committed audience into one that chooses to go deeper.

This is not the place to be thorough. Thoroughness is what the audience earns access to by stepping through the door. An introduction that front-loads evidence has confused the entry layer with the destination, and it loses the people it was built to bring in. The Triangle Pass exists to hold that line.

One — Name the One Thought

State the single framing claim of the topic in a sentence the audience could repeat to someone else. If the introduction covers several items, the whole introduction still gets one framing thought, and each item underneath it gets its own. If you cannot say it in one sentence, you are holding more than one topic and the opening will blur.

Two — Open on Their Stake, Not the System

The audience is the hero (canon/constraints/guide-posture.md). Lead with what is at stake for them — the friction they feel, the question they already have — before any system name, feature, or internal concept. The moment the first thing they encounter is "here is what we built," posture is broken and the door is heavier to open.

Three — Make It Land Once

Pay the thought down with exactly one illustration: a metaphor, analogy, example, or story (the M-A-E-S corner). One. The illustration's job at the entry layer is recognition, not proof — it lets the audience feel the thought is real enough to be worth pursuing. A second illustration is a sign you are trying to win the argument in the doorway.

Four — Point the Door at Real Proof

The next step (the A-or-N corner) names where the proof lives: read the essay, open the canon doc, see the data, listen to the full segment. This is the threshold. The introduction does not carry the evidence; it carries the address of the evidence. The handoff is the entire reason the entry layer is allowed to be light.

Five — Stop Before You Prove

This is the move that takes discipline. The instant you find yourself explaining the evidence, qualifying the claim, or walking through the detail, you have crossed your own threshold and pulled the audience past it. Cut it. Move it behind the door. An introduction that proves is no longer an introduction.

The weekly "this week on Klappy.dev" overview is the canonical surface for this method, because audio punishes overreach faster than text — a listener cannot skim past a paragraph of proof, they just leave.

Structure the overview as nested triangles:

• Open (one framing thought + their stake). One or two sentences on why this week is worth ninety seconds to the listener, not a table of contents of what shipped.
• Each item (one thought, one illustration, one door). Roughly fifteen to twenty-five seconds: the single thought, one quick illustration that makes it land, and the door — "the full story is in this week's essay." Three to five items, each its own triangle.
• Close (one next step). The single thing to read or do first. Not a recap of everything; the one door you most want opened.

The overview is the purest test of the method, because its only legitimate output is doors. Nothing in it should be the proof. Everything in it should make a specific piece of proof worth opening.

The one way this method fails dishonestly: a door that opens onto nothing. If the next step points to an essay that does not exist, a dataset that was never published, or a claim that is not actually supported anywhere downstream, the introduction has faked its strongest corner. A claim is a debt (canon/values/axioms.md, Axiom 2), and the door is a promise that the debt is paid somewhere the audience can reach. Promising proof you have not produced is the entry-layer version of lying.

So the pass has a precondition as well as a checklist: before you point a door, confirm the proof behind it is real and reachable. If it is not, you do not have an introduction yet — you have an unpaid claim wearing a confident opening.

This method governs the introduction and the handoff. It does not govern the proof, and it cannot override the documents it derives from.

• The entry layer is for restraint. When the pull to prove conflicts with the pull to be heard, at the entry layer being heard wins — because the proof is not lost, it is one step away behind the door.
• Every door must open onto real, reachable proof. No exceptions. A door onto nothing is a faked next-step corner.
• One framing thought, one illustration per unit. Overloading the opening is the most common way the pass is broken.
• The audience is the hero. If the introduction centers the system before the audience's stake, it fails guide posture regardless of how well it runs the other four moves.
• Sounds like a person, not a model. Especially in audio. Run the result against the ghost-writer test (canon/constraints/ai-voice-cliches.md).
• Restraint is the right bias for uncommitted audiences; it is the wrong bias for two specific cases. When the audience is skeptical or adversarial — a technical reviewer, an investor, someone who needs a credential before they trust the hook — light engagement before proof can read as hand-wavy and undermine rather than earn trust. Proof first may be correct there. When the audience is already inside — returning canon readers, the internal team — the door framing is unnecessary and can feel patronizing. The pass governs the entry layer for audiences who have not yet committed; it does not govern surfaces where commitment is already established or where credibility must precede engagement. If the restraint bias is wrong for a given surface, the whole pass is the wrong tool — what falls is not one move but the method's premise. Name the audience clearly before applying it.
• Experimental, applied universally until disconfirmed. This is the default method for the entry layer, used everywhere until a specific case disconfirms it or a better one earns the slot. Universal use is the practice; universal truth is not the claim. Retire or revise it if introductions built this way consistently convert worse than introductions that do not, or if a topic type emerges where the door-and-house split does not hold.

1. One thought: Can the audience repeat the framing claim in a sentence? (For multi-item formats: one framing thought overall, one per item.)
2. Their stake first: Does the opening lead with the audience's pain or question, not the system?
3. One illustration: Is there exactly one metaphor, analogy, example, or story, and is it honest to the claim's strength?
4. The door: Does the next step name where the proof lives — and does that proof actually exist and reach?
5. Restraint: Did you stop before proving? If evidence or qualification crept in, cut it and move it behind the door.
6. Recursion: At this scale, does the door hand off to the right next scale — overview to essay, essay to section, section to evidence?
7. Ghost-writer: Read aloud, does it sound like a person talking? (See canon/constraints/ai-voice-cliches.md.)
