Failed lifecycle verification could allocate another test environment every minute indefinitely. Count failed host verification tests separately from claims, persist a repair wait for confirmed configuration failures or three generic failed tests, and clear it through authorized retry or execution configuration changes. Preserve typed temporary execution-target failures through adapter checks so timeouts, transport failures and interrupted probes keep automatic recovery. Retain existing readiness, authorization, termination and cleanup gates. Document the policy and add real PostgreSQL persistence and actual OpenCode adapter regressions. Verified 398 focused tests (one Windows-only test skipped on macOS), repository-wide typecheck and build, structural checks, fully green current-head CI and Greptile 5/5 with no unresolved comments.

Feature modules
A feature module under server/src/modules/<name>/ uses three layers. Each
layer has one rule: which layer below it, it may import from.
adapters → application → domain
domain/holds pure business rules. A domain file takes plain data in and returns plain data out. A domain file must not importdrizzle-orm,@paperclipai/db, a service underserver/src/services/, a route underserver/src/routes/, or a Node.js I/O module (node:child_process,node:fs,node:net). A domain function must not read the system clock; the caller passesnowas an explicitDatevalue.application/holds use cases and the ports they need. A use case takes its ports as constructor arguments and calls domain functions for policy decisions. An application file must not importdrizzle-orm, a SQL client, a concrete adapter, or the server's HTTP error helpers. The outer service or route translates application errors into transport responses.adapters/holds the concrete implementations of the ports: Postgres queries, transactions, and process control. An adapter file may importdrizzle-orm,@paperclipai/db, and Node.js I/O modules.
A module exposes its commands through index.ts, which composes the adapters
and the use cases behind a factory function. Code outside the module imports
that entry point, never a file inside domain/, application/, or
adapters/ directly.
pnpm check:module-boundaries enforces these rules for production source
files. It also checks access to the company deletion entry point below.
Company deletion
The existing company deletion service owns the database transaction and deletion
order. A module can expose a separate company-deletion.ts entry point.
Only services/company-deletion.ts can import this entry point.
The entry point exports an implementation of CompanyDeletionParticipant from
lib/company-deletion.ts. Do not export it through the normal module index.
The service must complete external cleanup before it starts the transaction. It must lock the company before it deletes dependent records or calls a module. Creation commands must use the same company lock. The service removes dependent records before it calls the module. The module checks its deletion conditions and deletes the records it owns. Use the supplied transaction. Do not start another transaction or call external systems. Throw an error if deletion cannot proceed. An error must roll back all database changes in the deletion transaction.
Call each module explicitly in dependency order. No module registry is required.
The agent lifecycle module also has a restricted configuration.ts entry point.
It saves configuration and invalidates verification in the caller's transaction.
The lifecycle guide lists its permitted callers.
Ordinary configuration updates use the root lifecycle command.
The agent lifecycle module owns agent creation, pause, resume, and termination. Use its commands for these changes.
