Chinesezjc d7b4b014eb fix(tools): make py-types render total and bound deep class names
Address ds-review-bot v5/v6 review round 4:
- renderType now holds the no-throw contract across the whole walk, not
  just root validation: a stateful getter that passes validation and then
  throws in the render phase degrades the node to Any, rolling back any
  classes the call had begun emitting, instead of escaping.
- allocateClassName caps the accumulated base name. Child class names
  derive from their parent's, so an unbounded single-field object chain
  grew the sum of names to Theta(depth^2) (a 5000-deep schema produced a
  ~25MB SDK); the cap keeps total emitted text linear, the collision
  counter still makes truncated bases unique.
- The language-dispatch note's Consequences first sentence and the zh
  guard paragraph are corrected: two table entries (not one), and
  full-width Chinese punctuation per translation-rules.md.

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 (scope tags, scope-filtered dispatch) (library — no ctx key)
session/ Event-sourced session log + in-memory store ctx.sessions
system-prompt/ Prompt-section + tool-schema assembly registry ctx.systemPrompt
tools/ Scoped tool registry + pre-policy, guards, around-dispatch, post-policy, and final-result observation ctx.tools
agent/ Agent interface, live registry, process-local initiator scope, agent/* event vocabulary ctx.agents
agent-loop/ Concrete plugin implementing the public Agent contract and owning the loop driver ctx.agentLoop

scope/ is the one non-service package here: a dependency-free library (createScope/scopeOf/scopeTarget) the registries and the loop build per-agent scoping on — it sits below session/ and system-prompt/ in the module graph precisely so they can consume it without a cycle.

agent-loop is the one concrete implementation of the agent seam and lives here because it is the harness's default product loop. It runs each driver inside ctx.agents.withInitiator(). Extension plugins depend on agent, including when they need the initiating Agent, and never on agent-loop directly, so the loop stays swappable.

The default composition that wires this spine into a runnable agent lives in examples/agent-spine-demo: one bundle plugin that loads the control spine plus selected default capabilities (timer + llm + sessions + fallback session titles + system-prompt + tools + agents + invariants + the local skill family + tool-bash + workspace-context + agent-loop) and forwards agent-loop's agents list as its own config. It sits in examples/ — ready-to-run demo/reference bundles — not in core/: core/ ships the swappable spine pieces, while a demo bundle picks one concrete composition of them and adds a front door.
