- Intake / Main-PM / Cell-PM prompts: enumerate independently-shippable work
units, inherit the breakdown down the chain, and dispatch independents in
parallel (dependency order, never one-at-a-time).
- Raise the code-spine concurrency cap from 1 to 2 per parent (one per cell
developer) so both devs build in parallel; keep the same-assignee guard and
the planning/documentation cap at 1, plus the cross-team planning exemption.
- Split-before-claim: hard-block an egregiously-bundled code leaf at delegate
time so the PM splits it before any dev claims it; nudge the moderate band
in the delegate success envelope.
