MERGE_LABEL
constMERGE_LABEL:"__merge__"="__merge__"
Defined in: src/merge-suggest.ts:24
Marker prefix for the merge-suggestion pass’s ephemeral agents. Each run appends the
first 8 hex of its session UUID so concurrent runs never collide on the herdr name.
The underscores keep it collision-proof against [a-z0-9-] prompt slugs, and the
orphan-tab reaper matches this prefix (see tab-reaper.ts).
