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.
