The Agent Stack
CI tells you whether each branch passes.
We tell you whether they're compatible.
Parallel agents created a check that happens nowhere: between branch-level CI and merge-time integration, nothing asks whether the branches work with each other. Each one green on its own. Broken in combination. That's the gap this page maps.
Coordinate
CrowdedDecide who builds what. Workspaces, branches, task assignment, parallel sessions. These tools make many agents possible. Rosentic Init inserts here: runs start with sealed contracts, owned paths, and per-agent briefs, so the work is fenced before anyone writes a line.
Produce
CrowdedWrite the code. Agents that build, refactor, and review: brilliant in isolation, blind to their siblings. Each branch passes its own checks. None of those checks can see another branch.
Verify Compatibility
You are hereThe check that happens nowhere else: every pair of active branches, compared at the contract level: signatures, routes, schemas, before anything is queued to land. Deterministic, replayable, and it does not need a test to exist to see the break.
Proven in production, on ourselves: five agents across two vendors built a five-surface product in one night. Sixteen cross-branch scans, sixteen clean verdicts, zero shared-contract drift, and the cross-app integration test passed in 0.04 seconds against a 5-second budget. The clean sweep wasn't luck. It was the layer below doing its job.

Rosentic Check
The verification engine. Compares every pair of active branches, before merge: breaking signatures, route breaks, schema drift across 13 languages. Deterministic verdicts tied to a commit, replayable, contract-compatible or not.
Runs as: GitHub Action required check, seven MCP tools inside the agent loop, and enforced at the write and the push: hooks that fail closed on UNSAFE ship in the released package. Plus the fan-in gate before the human merges anything.

Rosentic Init
The constitution generator. Point it at your plan; it scaffolds the sealed contracts package every lane imports, marks the untouchable paths, emits per-agent briefs with gate rules baked in, and writes the run sheet. Drift stopped at the source, not caught at the door.
Born from the build above: the most powerful artifact of that night wasn't the scanner. It was the contracts-first lane and the rules around it. Init makes that one command instead of one expert.
Read the patternGovern
Rosentic Conduct
The run protocol. Sequence enforcement (contracts merge first, alone), plan-aware merge queues, contract-write permissions instead of prompt obedience, and a decision ledger: every agent judgment call logged as context, call, and risk.
Sits under every cockpit: Conductor and its peers make agents parallel. Conduct makes the parallel run governed: uninvited, git-compatible, no cockpit partnership required.
Follow the buildIntegrate
CrowdedLand the changes. Merge queues genuinely test combinations: queued changes, in landing order, using the tests you already have. What they cannot see: branches that are not queued PRs yet, and breaks no existing test exercises. Rosentic Conduct inserts here: sequence and contract-write permissions, enforced.
Operate
CrowdedRun what shipped. Errors, performance, incidents in production. By the time a cross-branch break shows up here, it is an incident. One layer earlier, it was free.
Each branch was right. Together they were wrong.
The verification gap is real and checkable today. Start with Check, free. Init and Conduct are being built in the open, on the same repo they were discovered in.
