v1.0.0 — First public release

v1.0.0 — First public release

Initial public release of the AetherCode Execution Engine — an on-premise,
distributed code-execution engine that accepts code submissions over HTTP,
runs them in isolated sandboxes, and streams verdicts back over
Server-Sent Events. Released under the
AGPL-3.0
license.

Highlights

• Distributed hot path — Go HTTP gateway → PostgreSQL (system of record) →
  Redis Streams (dual submit/run, weighted 3:1) → worker pool → go-judge
  sandbox → verdict, streamed back over SSE.
• 7 languages — C, C++, Java, Go, Python, JavaScript, SQLite, with
  per-language compile/run limits.
• Provable reliability — insert-before-enqueue, subscribe-before-replay,
  CAS verdict writes, orphan reaper + XAUTOCLAIM reclaimer. Zero lost
  jobs verified at 5,000 concurrent / 15,000 submissions (≈121 verdicts/s).
• Security & fairness — OIDC (Zitadel) auth, sliding-window rate
  limiting, queue-depth admission control, idempotency keys, weighted fair
  queuing.
• Observability — Prometheus metrics, pprof, structured JSON logs,
  per-request X-Request-Id tracing.
• Two modes — run (IDE / ad-hoc) and submit (graded problems with
  hidden tests).

Versioning

Releases are cut from the production branch (the default) using
Semantic Versioning tags: vMAJOR.MINOR.PATCH.

• MAJOR — breaking changes to the HTTP API, event protocol, or on-disk /
  stream formats.
• MINOR — new backward-compatible features.
• PATCH — bug fixes, dependency updates, and other non-breaking changes.

Pre-releases use a suffix, e.g. v1.1.0-rc.1. Every release must arrive
through the gated development → testing → staging → production flow with CI
(test + lint) green on each branch before it is tagged here.
