A control point inside a control point

Editor rewrite in stages: new renderer first, collaboration mode built on top of it.

TWO SHIPS, ONE GRAPH
The plan — drafted before anyone saw it
Strategy Stacked control points — the child cannot outrun its parent
Control points renderer (parent) · collab mode (child, nested inside)
Gates parent stable at each step before the child opens
Guardrails render errors · doc-sync conflicts
Rollback parent reverts → child goes dark with it, automatically
Ramp — planned outline, actual fill
25%
50%
child
100%
The run — from the decision log
T+0m read: collab mode compiles only against the new renderer — hard dependencyheld
T+2h chose: stacked control points — collab is a child, cannot outrun its parentheld
T+2d ramped: renderer to 50%; collab held dark inside itheld
T+4d opened: collab to renderer users only — the graph enforced the orderheld
T+6d done: two features shipped on one dependency graphheld
5 of 5 held · dependency never violated
