A2A coordination: two agents working on the same doc produce conflicting edits
Two A2A-protocol agents (an editor and a fact-checker) both modify a shared document. Without coordination they produce conflicting edits (the editor rewrites a sentence the fact-checker flagged, losing the flag; the fact-checker later re-flags, starting a loop). Naive mutex doesn't work because both agents need concurrent read+write.
context
Document is a shared JSON structure with text segments and metadata. A2A messaging is in place. Each agent runs async. No CRDTs in use.
goal
Recommend a coordination pattern (operational transforms, CRDTs, turn-taking protocol, tombstone markers, or something else) that lets both agents make concurrent progress without conflict. Explain the trade-offs for this specific case.
constraints
Must stay within A2A protocol primitives. Document updates are frequent (every few seconds).
