Pull Request Checklist

• PR title follows semantic convention: feat(scope): description, fix(scope): description, etc.
• PR body includes Closes #N reference (see Issue Gate)
• Tests added/updated: ./scripts/tri test passes locally
• Specs changed → seals refreshed: ./scripts/tri seal specs/path/to/module.t27 --save

Description

Agent network v1 on top of the orchestrator. Twenty-seven domains, one owner per spec, canonical id 0x<ROLE>@<domain>.t27. No command body is moved. The window shell stays blocked. Refs #13260. This does not close that issue.

Changes

• specs/t27os/agent_network.t27 — domains, names, registry, audit, and the blocked window
• specs/automation/t27_plan.t27 — six steps; the window check calls the network
• .claude/skills/agent-network/SKILL.md — the same rules, pointing at the spec

Testing

Typecheck of the network spec and the plan was reported OK on the source lane. Test bodies were not run. Seals were not refreshed. Regression was not run.

Documentation

The skill points at specs/t27os/agent_network.t27. Letter cards in specs/agents/ stay the path owners. This layer does not replace them.

Review Notes

Stacked on the orchestrator pull request. agent_network.t27 and t27_plan.t27 call orchestrator predicates, so this base is that branch, not master. Draft. Do not merge from this pull request. tri t27a spec scan is classified under T27A and is not a live command. Command bodies stay unmigrated.

Note

Medium Risk
New governance layer around orchestrator-gated capabilities and merge/window policy; behavioral impact is mostly spec/tests today, but it defines future agent/command routing contracts.

Overview
Introduces agent network v1 as a new T27OS contract in specs/t27os/agent_network.t27: 27 domains, scout/orchestrator/worker roles, packed ids, single-owner registration, capability grants tied to orchestrator allow-list plus audit, command classification (no body migration), and an invariant that the window shell stays blocked.

Adds specs/automation/t27_plan.t27, a six-step orchestrator plan whose tests assert ordering, commit vs merge policy, and that the plan still defers to an_window_stays_blocked and the network constants (AN_MIGRATED / letter cards unchanged).

Adds .claude/skills/agent-network/SKILL.md so agents load the same rules and point at agent_network.t27 and orchestrator.t27 before naming, registering, or classifying commands.
