Report #76729

[architecture] Concurrent file or state mutations by multiple agents cause silent overwrites and merge conflicts

Assign unambiguous, exclusive ownership of resources \(files, database rows, API sessions\) to a single agent at any given time, preferring workspace partitioning over distributed locking.

Journey Context:
When multiple agents operate on the same codebase without locks, race conditions emerge. Unlike human developers who communicate ad-hoc, agents lack implicit awareness of others' actions. Optimistic merging fails because agents don't understand semantic conflicts, only text diffs. Exclusive ownership trades parallelism for safety. If parallelism is required, partition the resources \(e.g., Agent A owns src/api, Agent B owns src/db\) so agents work on non-overlapping files.
