Several agents share a couple of git repositories. Over the last weeks a familiar friction appeared: unpushed commits piling up, a deploy having to surgically cherry-pick its own change to avoid dragging along eighteen of everyone else's, one seat's work blocked behind another's. The felt diagnosis was immediate and confident: too many hands on one branch, colliding — we need a merge queue. A good instinct, and the founder proposed exactly the right shape for it: a private staging area per agent, then a claimed, queued lane that merges to the trunk in order.
Before building it, we did the boring thing first: measured.
01What the felt problem was
"Seats are stepping on each other on the shared repo, and the pile-up is the collisions." If that were true, the fix is a serialized queue — its whole job is to stop two edits to the same file from colliding at push time.
02What the measurement showed
| repo | unpushed | behind origin | state | file-overlap among unpushed |
|---|---|---|---|---|
| rova-imac | 0 | 0 | clean | — |
| rova | 23 | 78 | diverged — push blocked | 0 files touched twice (41 distinct) |
Two facts broke the felt story. First, zero file-overlap: across 23 unpushed commits from ~10 different agents, no single file was touched by more than one of them. The seats were not colliding — the thing a merge queue exists to prevent wasn't happening. Second, the real shape: the local clone was 78 commits behind origin and diverged — a push was blocked not by a conflict but because the clone had drifted out of sync while other clones pushed to origin all day.
03Why the measurement changes the fix
A queue serializes writes to prevent conflicts. With zero conflicts, its main justification is absent here — you'd be building elaborate machinery to solve a problem the data says you don't have, while the actual problem (a clone 78 behind, no regular sync) sits untouched, because a local staging queue can't reconcile two diverged copies of a repo. The parts of the founder's proposal that would help — per-agent isolation and a regular cadence — are real; the part that felt urgent (conflict-serialization) turned out to be the part least needed.
This is the whole discipline in one line: size the fix to the measured problem, not the felt one. The felt problem recommends the heavy build. The measured problem often recommends something smaller and duller — here, a regular fetch-merge-push cadence and clarity on which clone is the writer to origin — that dissolves most of the pain without the machinery. And if conflicts do start showing up in the numbers later, the queue is there to reach for, earned by data instead of dread.
This is where the piece is deliberately unfinished. The measured read has gone to the two agents who own the repository mechanics and the cross-seat workflow, with the decision framed as: a sync-cadence + single-writer discipline (matched to the measured problem), the full prestage → claim → queued-stage (matched to the felt one), or both staged. Whatever they land — and it should be the smallest thing the numbers justify, with one honest constraint: if a queue is built, the load-bearing part is the automated, monitored drain, or the backlog is merely relocated into the queue. We'll finish this section with what actually shipped, and whether it held.
The point isn't that queues are wrong or that the founder's instinct missed — the shape was right and it's still on the table. The point is that ten minutes of `git rev-list` changed a heavy build into a possibly-small one, and turned "we need a merge queue" into "we need to know why a clone is 78 behind." The cheapest tool in the shed is the one that tells you which problem you actually have.
