- run-gates.ts docSyncLeafGates() gains verify-export-jsdoc — CI lanes and the pre-push hook execute this leaf list, not the doc-sync npm script, so the gate was previously unenforced there (proven by SessionForkErrorCode landing undocumented via a master merge while checks stayed green; now documented). Same wiring gap fixed for master's verify-config-catalog, which was also missing from the list. - The heritage exemption now recovers the base's return surface: a void base return carried no @returns duty, so an override returning a concrete result documents it itself (annotated overrides run the standard check; unannotated ones are classified by the checker so faithful void overrides need no boilerplate annotation). Three new negative-path tests pin it; RFC and module doc updated. - AGENTS.md states each principle inline instead of citing RFCs (eight citations removed; high-level doc links kept) and the editing section now carries the self-containedness rule. - Generated catalogs/graphs regenerated for the shifted line pointers.
core/ — product API spine
The packages every harness build is assembled from: the session log, the system-prompt assembly, the tool registry, the agent vocabulary, and the one concrete loop that drives them. These are product packages — the stable surface plugins and consumers build against.
| Package | Role | ctx key |
|---|---|---|
session/ |
Event-sourced session log + in-memory store | ctx.sessions |
system-prompt/ |
Prompt-section + tool-schema assembly registry | ctx.systemPrompt |
tools/ |
Tool registry + tools/pre-execute/tools/post-execute pipeline |
ctx.tools |
agent/ |
Agent interface, registry, agent/* event vocabulary |
ctx.agents |
agent-loop/ |
The concrete loop plugin: ReactLoopAgent + the loop driver |
ctx.agentLoop |
agent-core/ |
Bundle plugin: the providerless/executor-less/UI-less spine as code | (loads the spine) |
agent-loop is the one concrete implementation of the agent seam and lives here because it is the harness's default product loop; everything else in core/ is interface/vocabulary. Plugins depend on the agent vocabulary, never on agent-loop directly, so the loop stays swappable.
agent-core is the composition counterpart: one bundle plugin that loads the whole providerless spine (timer + llm + sessions + system-prompt + tools + agents + invariants + tool-bash + agent-loop) and forwards agent-loop's agents list as its own config. App packages (ui/stdio-agent, ui/acp-agent) consume it and add only a front door; a leaf adds the swappable backends plus any optional product tools it wants to expose. It lives in core/ because it composes exclusively core/ + interface packages and ships no provider, executor, or UI of its own.
