Chinesezjc 015bef2f5f docs(tools): widen the 182 reachability shape and finish the note's two language-binding facts
"Reachable only through a raw register() whose parameters is
array-rooted" was too narrow. A root oneOf reaches the same 182: the
union arm propagates listDepth unchanged because `A | B` opens no
bracket, so an array branch starts its chain at 0 exactly as an array
root does. Say "root opens an array chain -- rooted at the array, or at
an array branch of a root oneOf", in the JSDoc and the test comment,
and assert the union shape alongside the array-rooted one.

The note's Decision paragraph said the flavor guard is reached under
"a language that has a renderer but no flavor entry, and a test covers
it". The test uses ruby, absent from both tables, and the mechanism is
that schemas() reaches run_code's getters without passing
requireCodeRuntime -- so any language absent from the flavor table hits
it. State that instead.

The Consequences paragraph recorded the language-binding obligation as
two reads, assembly and execution. Within one projection there are more:
run_code's description and parameters getters each call
resolveFlavor(peekRuntime()) and schemaOf destructures both, so a reload
between them yields one schema whose halves name different languages.

core/ — product API spine

English | 中文

The session log, system-prompt assembly, tool registry, agent vocabulary, and concrete loop that form the harness's default control spine. These are product packages — the stable surface plugins and consumers build against.

Package Role ctx key
scope/ Scoped-context registration primitive library — no ctx key
session/ Event-sourced session log and in-memory store ctx.sessions
system-prompt/ Prompt and tool-schema assembly registry ctx.systemPrompt
tools/ Scoped tool registry and execution pipeline ctx.tools
agent/ Agent interface, registry, and event vocabulary ctx.agents
agent-loop/ Default concrete agent driver ctx.agentLoop

scope supplies the shared scoping primitive. agent owns the public seam, while agent-loop is its default implementation; extension plugins depend on the seam so the driver remains swappable.

Runnable compositions belong to examples/agent-spine-demo; this group owns only the swappable spine pieces.
