You are running the prepare-for-coordination workflow (knowledge/rigor-protocol.md). Lead peer: the Orchestrator, with the Enterprise Architect (module and bounded-context boundaries), the Data & Persistence Architect (the aggregate boundary is usually the right track boundary) and the SRE (long-running and destructive work - the case worktrees actually exist for). Adversaries: The Simplifier (soft veto - every track must justify the multiplier; the default is one session), the Test Architect (HARD VETO - a track with no exit evidence and no owner is not a track) and the Tech Lead (casting vote on track count).
Ground first and cite what you read: run coord doctor and pack-doctor.py --json and put the output in the plan - the layer's state is MEASURED, never assumed, because an uninstalled layer reports "0 decisions, nothing claimed" and that is indistinguishable from a working layer that saw no traffic (class CTX-H). Then the CTX-* and WT defect classes, the specs/ADRs/architecture, and git worktree list.
Interdict the rush: do not draw tracks yet. Contention is a property of the ARTIFACT, not the task - the six busiest files in the reference repo are all generated, so a lease aimed at authorship addresses a fifth of the problem. Classify first; it needs no coordination at all and it removes most of the contention.
STAGE 1 (highest ratio, do it first): coord-core.py classify init, then coord-core.py install, then coord-core.py doctor to read the state back. Extend the registry by hand with this repo's own generated and append-only artifacts, under the same rule - RUN the regenerate command before you write it. A refusal is the control working: a wrong command resolves every merge silently and leaves the artifact permanently stale while reporting as handled. Record that install runs ONCE PER CLONE, in the primary checkout: per-clone is not per-worktree, a linked worktree shares .git/config and .git/hooks and INHERITS the registration, and an install inside one overwrites the repository's with a path that dies with the tree.
OPEN: name the scope and the surface list it must reach (E7). INTERROGATE: bounded contexts, aggregates, and the real dependency edges - delete incidental ordering. EVIDENCE: every artifact the work touches gets a class and a reason; derived and register are marked no coordination needed explicitly, because that is the finding. A row that names a control's trigger QUOTES the ADR line with its citation, never a paraphrase - the paraphrase is where the width changes (DC-189). One owner is not the whole check (GO14a): for every shared surface, list each OTHER track's guard over it and show it jointly satisfiable with what the owner may write, and make every scan-shaped guard state its root, recursion, token set and allowlist to match the clause it discharges - widening reddens at the join, narrowing stays green. Apply GO5 independence (no data edge, no DECISION edge, no shared exclusive resource - all three) and the coupling test; every edge points one way, and a cycle is a boundary error rather than a scheduling problem. Name the SERIAL SPINE: until the interfaces are fixed, every track's result changes every other track's shape.
State the multiplier honestly: parallelism is a cost multiplier, not a saving (GO6, roughly 15x for orchestrator-worker exploration), and the objective is lexicographic - completeness and rigor, then token cost, then speed. What worktrees actually buy is isolation, machine-time parallelism and context hygiene (WT1a / CTX-A), none of which is speed. If the honest answer is one session, say one session.
DISCONFIRM: the Simplifier deletes every track that does not clear its multiplier and proposes the merged alternative; the Test Architect BLOCKS any track with no exit evidence; the Tech Lead decides the count. List struck tracks with reasons.
CONVERGE: write docs/coordination/<plan-id>.md (canonical, V2 frontmatter, machine-readable - /execute-with-coordination parses it) AND docs/coordination/<plan-id>.html (self-contained, dependency-free, theme-aware). Keep these headings and columns verbatim: Layer state | Artifact classes (path, class, mechanism, coordination needed) | Tracks (track, owns authored, depends on, tier, fan-out cap, budget, exit evidence, harness) | Serial spine | Seams | Struck tracks | Order of operations. For harness, name what a track NEEDS from a delegation mechanism (its own tree, a stated division, a receipt back) and record each harness as enforced / observed-only / unsupported from what you actually verified - never advertise a mode you have not exercised.
End with the status table (Completed | Remaining | Best next action).
Last action - discoverability (V10): write the artifact's frontmatter and sync the derived index via python3 docs/ai-forward-pack/scripts/docs-graph.py derive - no ad-hoc scripts (V18); verify it is linked into the graph.
Running this in Copilot (single agent - make the dialog visible). Copilot does not auto-spawn the personas as separate subagents the way Claude Code does, so enact the round-table inline: for each peer write a short labeled contribution in that persona's voice; then run the adversary round, each reviewer giving a labeled critique with a severity [Blocker|Major|Minor|Nit] and, for hard-veto roles, an explicit PASS/BLOCK plus the veto-clears-when predicate (persona-cards.md 8). Do not collapse this into one unattributed answer.
