Chapter Bridge

How the pieces fit together, and where to put which kind of instruction.

The three pages

Bridge — your chapter pool, arrangements ("orders"), and the transitions/intros between chapters within an arrangement.
Write — where each chapter's actual content gets drafted, refined, and (optionally) adapted into an arrangement's style.
Settings — everything global: project selection, the two framing fields, the system instruction, and the structure/example template + example chapters.

Four kinds of instruction, four different jobs

Every setting feeds a specific generation step — nothing is shared automatically between all of them. Put an instruction in the wrong field and it simply never reaches the model call it was meant for.

Field Feeds What belongs here
System instruction Everything — Draft, Refine, transitions, adaptation Rules with zero exceptions: fixed output language, units, formatting bans.
General content framing Draft & Refine (Write page) only Factual context: audience, goal, what the tutorial covers. No tone.
Structure / example template Draft & Refine (Write page) only What every chapter must structurally contain — required sections, a recurring exercise, a running narrative element.
Arrangement framing Transitions & "Adapt to arrangement" (Bridge page) only Voice/tone for how a specific arrangement is delivered.

One important asymmetry: adaptation is explicitly told to preserve structure and facts exactly, changing only wording and tone. So even a well-placed structural instruction in Arrangement framing would be ignored during adaptation — structure only ever comes from the Structure/example template, because that's what Draft and Refine actually read.

Worked example

A real prompt that mixed all three concerns, and how it splits up:

"Schreibe für Kinder in der 5. Klasse in einem lockeren, motivierenden und interessanten Ton [...]. Denke dir auch Experimente aus, die man auf einem Breadboard bauen und ausprobieren kann [...]. Nimm Bezug auf RobertOne, sodass die Kinder immer einen praktischen Bezug haben [...]. Schreibe keine Einleitung und keine Überleitung zum nächsten Kapitel [...]. A tutorial for learning electronics based on a robot called RobertOne. The kit consists of: wooden base, 2 TT motors with wheels, ESP32-S3 microcontroller, DRV8833 motor driver, L7805 voltage regulator, ultrasonic sensor, breadboard, assorted components."

This single block mixes three different jobs. Split apart:

PieceGoes inWhy
"lockerer, motivierender Ton für 5. Klasse" Arrangement framing Pure tone — varies if you ever deliver this tutorial with a different voice.
"Denke dir Experimente aus", "Bezug auf RobertOne", "keine Einleitung/Überleitung" Structure / example template Structural requirements — must reach Draft/Refine directly, or they never appear in the content at all.
The kit parts list, "tutorial for 5th graders on electronics" General content framing Factual context the content itself needs, independent of tone.

With the original version, Refine on the Write page would never add an experiment section — that instruction lived in Arrangement framing, a field Draft/Refine never reads.

Quick troubleshooting

"Refine isn't applying my structural instruction." — it's probably in Arrangement framing or a per-arrangement Style/Instructions field. Move it to Structure/example template.

"Adapting to an arrangement changed the content's structure/facts." — that shouldn't happen; adaptation is instructed to preserve structure exactly. If you're seeing this, try regenerating — it may be a one-off model deviation rather than expected behavior.

"I want a rule to apply absolutely everywhere, no matter what." — put it in System instruction on the Settings page, not either framing field.
