A shared source of truth for on-call rotations, replacements, escalation policies, and routing. Rust + Cot 0.7 (HTTP, ORM, migrations), PostgreSQL, and locally vendored Alpine.js. The interface is English. Providers receive calculated intervals and execute notifications/escalation timers.

Start locally

On Windows with the PostgreSQL server binaries installed:

./scripts/dev.ps1

Open http://127.0.0.1:3000. The script starts disposable demo mode: accounts admin (instance administrator), alice (administrator of the demo workspaces) and bob, carol, dave, erin (employees) share one password that is generated on every start and shown on the login screen and in target/local/app.log. Stop with ./scripts/stop-dev.ps1. Pass -PostgresBin PATH if PostgreSQL is elsewhere. Local data and logs live in ignored target/local/.

On other platforms, create a PostgreSQL database, set the environment variables in .env.example, then run cargo run --locked. Use postgresql:// URLs. MEGURI_SEED_DEMO=true starts the disposable demo and works only on loopback. Any other run needs an instance configuration file (MEGURI_CONFIG_FILE, see deploy/instance-config.example.yaml); without it startup fails. Environment files are not automatically loaded.

Implemented

Independent workspaces declared in an instance configuration file, OpenID Connect sign-in with group-to-role mapping (instance administrator, workspace administrator, employee), optional password and bootstrap accounts, and durable audit/history.
Calendar-day rotations with IANA timezones, ordered participants, anchors, absence fallback, holidays, and escalation backup schedules.
Replacements and atomic reciprocal swaps; confirmation by the other employee or forced application with a reason.
Durable publication, optimistic revisions, worker leases, retries, checkpoints, external drift protection, and a downloadable preview.
Mock provider and a JSM Operations API adapter for schedules, escalations, and routing.

Working through agents

Start with AGENTS.md. Describe intended behavior and examples to the agent; it must update the specification, implementation, and relevant tests together. Product, architecture, test strategy, development, and deployment are maintained project inputs.

cargo fmt --check
cargo clippy --all-targets -- -D warnings
cargo test
cargo test --locked --tests -- --ignored --test-threads=1

The ignored suites require MEGURI_TEST_DATABASE_URL for a disposable PostgreSQL database whose user may create databases. CI runs them explicitly; ordinary unit tests need no database or external account. Browser checks (npm run test:browser) run against a freshly started demo.

Current boundaries

Sign-in is OpenID Connect (code flow with PKCE) and was tested against a fake provider only; verify your Keycloak client and group mapper as described in deployment before relying on it. There is no self-registration and no in-app workspace creation. JSM has local HTTP contract coverage and still needs acceptance testing against a dedicated JSM test team and your subscription. GKE manifests are deployment templates, not an already deployed environment. No alert ingestion or notification engine is included.

The ignored opsgenie-master/ directory is local reference material. Its behavioral examples are captured in the product contract and tests; application and CI do not depend on it.

Demo mode is disposable: MEGURI_SEED_DEMO=true resets only positively marked demo data on restart and expires temporary resources while running. Unmarked/normal databases are protected and trigger an isolated demo database with a permanent warning. See demo lifecycle and retention settings. Alice administers four generated examples; Bob demonstrates Engineering on-call, Carol daily Support shifts.
