Adds an opt-in adaptive coordination layer. The default hod workflow is completely unchanged unless you explicitly ask for an adaptive coordinator or coordinator-plus-advisor setup.
What is it?
A request-driven routing system that picks the smallest workflow that fits:
DIRECT— fast path for questions, explanations, and read-only inspection. No worker, no plan, no advisor, no checkpoint.SINGLE— one task packet for a clear, reversible, single-owner change.ORCHESTRATE— working plan, explicit ownership, and ordered coordination for multi-writer, multi-phase, or large-blast-radius work.
CONSULT and ASK_USER are overlays, not additional modes. Every repository change still gets a mechanical E0 evidence receipt before acceptance. Tripwires hold before re-routing — they never auto-revert, open new writers, or expand permissions. Advisors (user-chosen from Fable, GPT-5.6 Sol, or Opus) receive self-contained decision packets and return assessments only, never authority.
Six reasoning principles are embedded as observable output rubrics: floor check, concrete simulation, adversarial self-review, constraint loop, multi-hypothesis diagnosis, and calibrated delivery.
What it is not
This is not a new CLI command. bin/hod only changes one line — the version number. No new subcommands, settings profiles, lock files, ledger helpers, or stale-lock recovery code.
One additional fix
features.multi_agent=false is now documented as version-sensitive on interactive Codex: the gap was confirmed on 0.146.1 and observed as resolved on 0.147.0. Probe the exact installed binary before relying on the flag.
