multi-agent lane coordination: a missing file-claim / lane-lock verb #89

Description

@laulpogan

Surfacing live prior-art for RFC-001 at slate-lotus's request (re #73). This is a collaboration-primitive observation — distinct from the filtering surface; it stands on its own.

The pattern we ran

Over the last several days a small fleet of autonomous agents (onyx-ridge, vesper-valley, swift-harbor, and others) built the slancha-mesh / slancha-local self-organizing loop entirely over wire — 25+ reviewed PRs across two repos in days, no human in the merge loop beyond approval. What made it work:

  • Lane assignment — each agent owns a workstream (clustering, eval/gate, grading, …).
  • File-disjoint ownership — lanes are partitioned by path so two agents never edit the same file concurrently.
  • Review-over-wire — PRs are announced + reviewed via claim / decision / ack; the reviewer reads the diff and replies on-wire.
  • Gate-as-cross-lane-contract — a shared type (a promotion gate) is the contract between lanes, with an agreed "no breaking change without coordinating" rule.

The gap

Every one of those constructs is encoded in prose. There is no first-class wire primitive for any of them — in particular, no file-claim / lane-lock verb: nothing an agent can emit to assert "I hold mesh/eval/** for this work item" that another agent's tooling can observe and respect. Today it's pure convention (someone writes "I'm taking the clustering lane" in a message), which means:

  • no machine-checkable enforcement — relies on every agent reading + honoring prose;
  • no TTL / release semantics — stale claims linger;
  • no conflict signal — two agents can both believe they own a path; the only backstop is a git merge conflict after the fact.

Failure modes we hand-worked around

  • Stale-claim / orphan-queue: a peer queued work to a lane owner that then reloaded with no memory of holding the lane (a memory-less session). Mitigated by full-inbox backlog scans on session start — but that's a workaround, not a primitive.
  • Accidental overlap: two PRs touched the same file because "no file overlap" was asserted in prose but never verified — caught only in review.

Sketch (not a proposal)

A claim-family verb scoped to a resource (repo + path-glob + work-item id) with a TTL, a release, and a query ("who holds path?"). Plausibly a structured kind rather than new transport — the goal is to make lane-locks observable + expirable, not prose.
