This repository is the compatibility boundary between the fast-moving OpenCode server and the clients and host applications that depend on its HTTP, SSE, plugin, and runtime behavior. It contains only synthetic fixtures and public image coordinates; no production prompts, credentials, sessions, or user data belong here.

Policy

An unpublished gem build is a candidate until the fixture suite and every required image profile pass. It is identified only by an exact commit.
opencode-ruby and opencode-rails are one candidate release train. The manifest records both exact commits, and CI rejects a Rails candidate whose exact runtime dependency resolves to a different Ruby version or commit.
Once a train is published, commit-only provenance is no longer accepted. The manifest and lockstep contract require each annotated tag object, local tag ref, and peeled commit to bind to the tested checkout.
Image references are immutable OCI index digests. A tag may be recorded as human-readable provenance, but it is never an execution coordinate.
Custom consumer images are certified with an isolated canary on the host that can pull them. Public CI certifies their upstream base plus the same profile.
Promotion is explicit. CI may certify a tuple and the watcher may open a PR; neither workflow deploys or changes a consumer.
Each consumer retains both current and previous certified tuples so a rollback restores the gem and server together.
A failing bootstrap baseline is never relabeled as a certified previous tuple. Promotion stays blocked until a distinct rollback consumer commit is pinned to a passing client/runtime tuple and canaried.

What is covered

The corpus exercises both historical and current terminal events, delta-before- part ordering, authoritative final text, reasoning text, aggregate multi-step usage, interactive question and permission waits, unknown-event tolerance, the subscribe-before-prompt ordering contract, and reconnect without prompt replay.

Profiles keep the ownership boundaries explicit:

ruby-rest-sse: the opencode-ruby HTTP/SSE adapter.
rails-persisted-turn: Rails lifecycle, persistence, and recovery semantics.
voice-stream: Greenroom's voice/LiveKit stream semantics.
strict-v2: Leela's strict version and route-ownership gate.
plugin-ledger: Ajent/plugin hook and ledger behavior.
provider-hooks: inference provider configuration and hook behavior.

The live contract starts a deterministic local OpenAI-compatible model stub and an isolated OpenCode container. It creates a session, subscribes, submits an async prompt, observes terminal SSE, fetches the authoritative exchange, and deletes the session. Passing requires the authoritative final text to equal the expected text byte-for-byte and the deterministic model stub to observe exactly one request and exactly one authoritative assistant message. It never calls an external model provider.

Candidate CI uploads machine-readable fixture, lockstep-client, and exact-image evidence for 30 days. These artifacts are review inputs, not certification by themselves. A person must review a passing artifact and commit the durable certification document under evidence/; no workflow commits or promotes its own result.

manifests/image-matrix.json binds the active pending matrix to both candidate commits. Its previous_certification entries preserve the last alpha7 result; they do not certify alpha8. Ajent and Mushu custom-image rows remain pending until their host canaries run against this exact pair.

The checked-in alpha8 local exact-image result is explicitly marked not-certified and shared-client-contract-only. It proves the Ruby/SSE probe on the recorded image IDs but does not claim Rails, plugin, application, or deployment canary coverage; exact-head CI still supplies reviewable workflow provenance.

Adding an upstream release

The scheduled watcher compares both the latest upstream GitHub release tag and its resolved OCI digest with the manifest. A new release or a changed digest behind an existing tag gets a digest-specific branch and compatibility PR. The PR adds a pending image-matrix entry, which runs the candidate suite after the normal GitHub workflow approval boundary. A person still decides whether to promote it and update consumers. The watcher never merges, dispatches consumer workflows, deploys, or force-pushes.

public_ci is the active compatibility set, not an append-only release log. Keep images still referenced by a consumer's current, candidate, or previous runtime tuple plus the newest pending upstream candidate. When a watcher PR supersedes an unreferenced pending target, remove that older row during review; durable certification documents and Git history are the archive. This keeps a fast-moving upstream from making every future run retest every old release.
