docs/20 builds the engine and the boundary: the startup order, the starfield, actors and collision, booting a DEF-only script, the issue #8 mode workaround, the custom update hook, first light, screens, and the headless harness. docs/21 builds the three shared structures and the AI: the host type tables, the actor binding, the randomness route around issue #16, the measured case against structure arguments (issue #36), the three language rules that shape the script, the maneuvers, the argued formation decision, the script-death policy, and the interop proof. Every fenced block runs under tests/docs_examples.sh in both build configurations; five new preludes carry the C fragments. docs/10 gains the 'Calling a function every frame' section the chapters lean on: the per-call akbasic_environment_zero() rule, the set_mode(RUN) workaround, the clear_error() revival, and the case for rebinding over structure arguments. Index rows and chapter counts updated.

* Prelude for the interpreter-facing fragments in docs/20: the boot sequence,
|
|
* the ADDEM proof and the rebind-call-reset protocol, shown as runs of CATCH
|
|
* calls. The statics are the ones examples/galaga/script.c keeps; the locals
|
|
* are the superset every fragment draws from, void-cast in the postlude so an
|
|
* unused one is not a warning.
