ATM Lock

First command:

node atm.mjs next --prompt "$ARGUMENTS" --json

Route Command

Use this ATM command only after the first command confirms it is the current governed route:

node atm.mjs lock check --json

Mutation safety checks should use ATM guard commands:

node atm.mjs guard mutation --task <task-id> --actor "$ATM_ACTOR_ID" --files <csv> --json
node atm.mjs guard git --task <task-id> --actor "$ATM_ACTOR_ID" --json

Handoff

node atm.mjs handoff summarize --task "$ARGUMENTS" --json

Charter Invariants

• INV-ATM-001 ??No second registry (enforcement: gate, breaking change: yes) Rule: A host project must not create a second AtomicRegistry implementation outside of packages/core or introduce a parallel ID allocation, version tracking, or registry promotion path.
• INV-ATM-002 ??Lock before edit (enforcement: doctor, breaking change: no) Rule: No governed file mutation may occur without a valid ScopeLock recorded in .atm/locks/ for the current WorkItem. Agents must call atm lock before editing files.
• INV-ATM-003 ??Schema-validated promotion only (enforcement: gate, breaking change: yes) Rule: An UpgradeProposal must pass all automatedGates (including JSON Schema validation) before promotion. Direct registry mutation that bypasses the UpgradeProposal path is forbidden.
• INV-ATM-004 ??No competing highest authority (enforcement: doctor, breaking change: yes) Rule: No host project rule, profile, or configuration may declare itself to have authority equal to or higher than the AtomicCharter. Any rule that contradicts an invariant must go through a charter waiver proposal.
• INV-ATM-005 ??Host rule amendments require waiver flow (enforcement: waiver-required, breaking change: no) Rule: When a host project rule conflicts with a charter invariant, the host must submit a behavior.evolve UpgradeProposal with a charterWaiver field and a linked HumanReviewDecision. Silent override is not permitted.
• INV-ATM-006 ??Framework work tracking stays target-local (enforcement: doctor, breaking change: yes) Rule: The framework repository must not host downstream adopter planning queues or project-specific work tracking artifacts. ATM framework-development tasks may live in the framework repository only as ATM-managed .atm/history/tasks ledger records with CLI transition evidence.
• INV-ATM-007 ??Public framework docs remain English-only (enforcement: doctor, breaking change: yes) Rule: Public contributor-facing documentation in the framework repository must remain English-only and repository-neutral. Non-English planning notes, local experiments, or downstream operating guidance must live in the coordinating host workspace unless they are translated into neutral English framework documentation.
• INV-ATM-008 ??Broker tickets, not refusals (enforcement: doctor, breaking change: no) Rule: Every governed shared-write gate (runner-sync, build windows, release mirrors, git commit, projection regeneration) must respond with a broker ticket - execute now, enqueue with position, or batch into a shared write window - never a bare refusal. Reads and private writes (own ledger, evidence, task events, lane sessions) never queue. The only standing exceptions are the four owner-ruled cases in docs/governance/parallel-governance-charter.md; any new serialization point requires an explicit project-owner ruling before it ships.

Guardrails

• Stay inside ATM CLI routing and evidence contracts.
• Do not create a parallel task model, registry, or approval flow.
• Treat any planning hint as CLI output, not as template authority.
