Module layout 

Pane-layout calculation for supervisor-mode tmux sessions.

v0.5.0 supervisor mode arranges panes as:

• Pane 0: supervisor agent (50% width of top row)
• Pane 1: dashboard (50% width of top row)
• Panes 2..N+1: coding agents, row-major, up to SUPERVISOR_AGENTS_PER_ROW columns per row

Vertical proportions vary with the total number of rows. See openspec/changes/supervisor-as-pane/specs/tmux-orchestration/spec.md.

Structs

SupervisorLayout

Computed layout parameters for a supervisor-mode tmux session.

Constants

SUPERVISOR_AGENTS_PER_ROW

Agents per agent-grid row for v0.5.0. Hard-coded; configurable in v1.0.0.

SUPERVISOR_MAX_AGENTS

Maximum agents per supervisor session for v0.5.0. Above this, the launch is rejected with an actionable “split into multiple sessions” error. Configurable extension deferred to v1.0.0 (issue #17).

SUPERVISOR_PANE_OFFSET

Offset applied to agent-pane indices in supervisor mode: supervisor at 0, dashboard at 1, so the first coding agent lands at pane 2.

Functions

layout_for

Pure grid-geometry function of agent count, named per the add/remove design (D1). The v0.5.0 layout builder (supervisor_layout) is already a pure function of agent_count; layout_for is the canonical name the add-branch / remove-branch specs use to make explicit that the same geometry is recomputed for N → N+1 (add) and N → N−1 (remove) re-tiling, not just the initial start-time layout.

supervisor_layout

Compute the layout for a supervisor session with agent_count coding agents.
