Umbrella for the 2026-08-08 task-stack campaign.

Root Justification

Campaign epic. Three defect classes diagnosed before launch:

• D1 parent laundering (live producer).gardener apply (12h timer) writes an LM-guessed parent: marked inferred: [parent] into the mirror. corpus.tasks.sync pushes parent to Plane as a normal issue field, but the inferred marker never round-trips. The next pull re-renders from Plane, so a speculative guess becomes indistinguishable from operator intent. MEMY-926 (a NOWHERE-sentinel bugfix) thereby acquired 15 unrelated live children; adoption timestamps match the gardener tick to the second.
• D2 phantom comments (mirror-side). MEMY-421 and MEMY-327 carry plane-comment-id blocks in the mirror for comments that do not exist in Plane. 1555 comment blocks across 590 mirror files need auditing.
• D3 stale SID cross-references._draft-pop-050.md was recorded as promoting to MEMY-327 (an origami card) when pop-050 is in fact MEMY-365; the wrong SID propagated into MEMY-954 and MEMY-273 prose.
