Discovery and Quality Graph
The Go service maps application structure and test obligations without executing repository code or retaining source files.
Capabilities
Map application coverage, plan tests around changes, and review the evidence behind release decisions.
Architecture
Sentinel merge policy
Sentinel signs independent release decisions. Critical findings block merges regardless of the overall score.
Test precision and runner permissions
Blocking tests require positive and negative validation cases. Droplet quarantines tests below 90% precision and checks runner permissions through SpiceDB.
Append-only evidence ledger
Evidence collection and approval are separate. The ledger records each verdict and time-limited human override.
From repository to release evidence
- Inspect the repositoryMap application topology without executing source code.
- Plan and run testsPrioritize coverage gaps and the impact of changes.
- Evaluate the gateSentinel makes an independent merge decision.
- Record the evidencePreserve verdicts and evidence in the append-only ledger.
Technical capabilities
Safe Non-Executing Code Discovery
Analyzes repositories to construct the Quality Graph without running untrusted build scripts or storing raw source file contents.
Release confidence
See where missing evidence increases uncertainty about a release.
Independent merge decisions
Sentinel separates evidence collection from merge policy. High-risk overrides require an authorised person.
Append-Only Drift & Re-Judgment
Preserves immutable verdict history so policy updates or re-judgments report decision drift without rewriting prior audit records.
Core capabilities
Droplet connects discovery, testing, policy and evidence into a clearer quality engineering practice.
Non-executing discovery
Inspect application structure without running untrusted repository code.
Quality graph
Connect components, quality obligations, coverage and evidence.
Targeted test plans
Prioritize tests according to changes, gaps and impact.
Policy authority
Preserve independently governed release-blocking decisions.
Traceable evidence
Keep release judgments connected to the proof that supports them.
Confidence insights
Show uncertainty and blockers explicitly rather than masking risk with a single score.
