/work and tracked plans

Cross-model handoff is now a git-tracked tree, not chat archaeology. Ready plans live under .plans/; executors start with /work, honor each plan's Preferred models, and archive only when Done when holds.

Until now, the orchestrator pattern assumed you would park plans somewhere and remember which model should run them. Anchor makes that explicit: scaffold installs a .plans/ tree (bugs/, features/, in-progress/, ambiguous/, blocked/, drafts/, completed/) plus a process contract in .plans/README.md. Plans are markdown; the tree is git-tracked. Private experiments use <slug>.local.md.

/work is the shared entrypoint (Claude: .claude/commands/work.md; Grok: .grok/skills/work/SKILL.md). Bare /work resumes own in-progress/, then picks the highest-priority model-fit ready plan whose Depends on are met. Flags: /work --list, /work --no-fit-check, /work <slug>. For always-on pullers, /fleet-watch installs reboot-persistent timers.

Fit and dependencies are intentional economics. Headers carry Preferred models and Depends on (other plan slugs, or none). Expensive tiers skip cheap work; small models skip architecture; nobody starts a plan while a dependency is still open. Set a Preferred orchestrator per project; if unset, frontier/near-frontier may act as temporary coordinator.

Promotion is human-only (drafts/ → ready). Agents claim ready → in-progress/, finish → completed/, and may park half-baked or stuck work in ambiguous/ / blocked/. Headless: work_once.py or orchestrate.py --plan-file (refuses non-executable lanes). Optional: python scripts/check_plans.py.

Start from Skills → /work and Tooling → Fleet workers.
