Master arrivals re-grafted onto the plan-mode surfaces: - Package invariant runtime contracts: every package owns ./invariant — added the dsh-mode companion (mode/set payload validation: non-empty trimmed name), its unit spec, exports/peer wiring, and the mode group in the tsconfig invariant paths glob. - Interception waterfalls gained an AbortSignal parameter (agent/prompt-submit, agent/turn-continuation) and ToolExecutionInput.signal became required: listeners and test dispatch updated; the exit tool now forwards exec.signal unconditionally. - TUI question dialog: master's position/unanswered header layout kept, the plan-review detail block re-grafted between question and answers. - LSP capability family arrived: lsp tool joins the catalog pin, dsh-lsp examples deps beside dsh-mode; lsp-definition snapshot refreshed with the mode command and modes advertisement. - docs/architecture.md and packages/README.md regenerated tables re-grafted (ctx.modes row, mode package row) and condensed within word ceilings. - examples/acp-agent cordis.yml: kept the deployment-owned plan instructions (incl. the conversational-agreement sentence) beside master's routed-model compaction comment; snapshot expected outputs refreshed keyless and noise fixtures restored.
core/ — product API spine
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 + 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.
