Release Control System

YOUR CI IS GREEN.
YOUR RELEASE
ISN'T READY.

Dulvarn gives every pull request an explicit GO, CONDITIONAL GO, or NO-GO decision — backed by deterministic release gates, test drift detection, and AI advisory analysis.

Capabilities

Built for engineering teams
that take quality seriously.

RELEASE.GUARD

Available

Deterministic release gates that block bad merges before they reach production. Code freeze, snapshot locks, required checks — enforced automatically. No exceptions without an explicit override.

TEST IMPACT (TIRI)

Beta

Maps every code change to its tests. Detects drift — tests that no longer cover the code they were written for. HIGH RISK drift blocks the merge until a human overrides.

RELEASE.COPILOT

Beta

AI advisory analysis on every PR. Risk summary, impacted areas, suggested tests. Advisory only — never gates your release automatically. You decide.

RELEASE.SNAPSHOT

Available

Lock the state of a release — test integrity score, drift status, CI checks. Snapshots are immutable. If something changes after the snapshot, the gate recomputes.

RELEASE.FREEZE

Available

Code freeze windows with hard and soft modes. HARD freeze blocks all merges. SOFT freeze warns and requires explicit override with audit trail.

RELEASE.SIGNALS

Coming Soon

Aggregates CI status, test results, coverage, security scans, and build artifacts into a unified signal layer. One source of truth for release readiness.

Process

Zero configuration.
Instant intelligence.

01

Install the GitHub App

One click. Dulvarn connects to your repositories.

02

PR triggers analysis

TIRI maps code changes to tests. Release Copilot runs advisory analysis.

03

Guard computes decision

Deterministic rules + test integrity + risk score → GO / CONDITIONAL GO / NO-GO

04

Gate enforced on GitHub

NO-GO blocks the merge. Your team sees exactly why. Override requires a reason.
