Chinesezjc 9bba851a62 fix(tools): correct the trim-order claim and check the Literal escape dependency
trim and escape commute for every input, so the new whitespace test does
not pin their order: UNPRINTABLE and LONE_SURROGATE are disjoint from the
set trim() strips, and both escapes emit plain non-whitespace ASCII,
leaving the leading and trailing whitespace runs byte-identical. State that instead of the false causal clause.

pyScalar's Literal path escapes nothing itself -- JSON.stringify is what
keeps it parseable, covering NUL and, under ES2019 well-formed
stringification, unpaired surrogates. Record the dependency and turn it
into a checked invariant. Pin the docstring emission site for a lone
surrogate too, mirroring the NUL case.

Two docstring corrections: describe's caller enumeration omitted the
synthetic { description } wrapper docLines builds, and "special in
statement position" does not describe `_`, which is special in a match
pattern. Both keep the conclusion they support.

Note which of the two table guards fires depends on the entry point.

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.
