+# Maintaining OpenCode consumers
+
+OpenCode compatibility is an executable tuple, not a gem version. The tuple is
+the exact client commit, Rails adapter commit where used, OpenCode image digest,
+consumer commit, compatibility profile, and passing evidence. A change to any
+coordinate creates a new candidate.
+
+## Dependency ownership
+
+The adjacent projects intentionally do not all use the same gems:
+
+| Consumer | OpenCode boundary | Owned dependency |
+| --- | --- | --- |
+| Ajent Rails | Ruby REST/SSE plus persisted Rails turns | `opencode-ruby` and `opencode-rails` |
+| Travelwolf | Ruby REST/SSE plus persisted Rails turns and Sprite lifecycle | `opencode-ruby` and `opencode-rails` |
+| Mushu | Ruby REST/SSE with application-owned conversation, claim, recovery, Telegram scope, and idempotency | `opencode-ruby` only |
+| Greenroom | Direct voice-stream worker | No Ruby adapter gem |
+| Leela | Custom strict-v2 server, security, and toolchain lane | No Ruby adapter gem |
+| opencode-ajent | Native CLI and plugin hook/event lane | No Ruby adapter gem |
+| inference | Provider configuration, hooks, routing, and migration lane | No Ruby adapter gem |
+| Context Kit | MCP and OpenCode configuration producer | No Ruby adapter gem |
+
+Do not add `opencode-rails` to an application that owns different persistence
+semantics, and do not route plugin, provider, voice, or strict-v2 behavior
+through the Ruby REST/SSE adapter merely to make versions look uniform. Share
+fixtures, provenance, and promotion policy across those lanes instead.
+
+Generated release snapshots, detached operational copies, editor locks, caches,
+and linked task worktrees are evidence or tooling. They are not additional
+consumers and must not be bulk-upgraded.
+
+Direct consumers still need immutable inputs even though they do not use the
+Ruby gems. A system service must execute a clean certified checkout or image,
+not whichever files happen to be in a mutable development worktree. Node and
+Bun plugins must be pinned through their package lock and tested against the
+same OpenCode digest; a globally cached, unversioned plugin is not release
+provenance. Generated OpenCode or MCP configuration needs both schema validation
+and a candidate-runtime smoke test. Keep OpenCode auto-update disabled in every
+certified lane so a process restart cannot silently change the server half of a
+previously passing tuple.
+
+## Supported window
+
+Support the exact current and previous certified runtime tuples. Do not claim
+compatibility with arbitrary future OpenCode versions. Additive fields and
+unknown events should remain tolerant, while terminal text, request count,
+ownership, persistence, and cleanup invariants remain strict.
+
+The Ruby/SSE profile covers the endpoints and events the client actually uses,
+including session creation and deletion, asynchronous prompts, event
+subscription, status, terminal idle/status events, part deltas and updates,
+authoritative assistant messages, questions, and permissions. A passing shared
+profile does not certify Rails persistence, voice streaming, plugin hooks,
+provider migrations, or generated MCP configuration.
+
+## Release and promotion order
+
+1. The watcher records a new upstream release tag and resolved OCI digest in a
+   PR. It never merges or deploys.
+2. Update fixtures for any observed protocol change before changing the client.
+3. Build `opencode-ruby` and `opencode-rails` as one release train. Rails must
+   resolve the exact Ruby version and commit being tested.
+4. Run the shared fixture corpus, Ruby 3.2 through 4.0 lockstep matrix, and every
+   exact public image still used by a current, previous, or candidate tuple.
+5. Run only the application-owned profiles for each consumer, in its own PR and
+   isolated environment. Health checks alone do not certify a tuple.
+6. Promote and deploy one consumer at a time. Record the exact production
+   commit, image/base digest, loaded client commits, and live result.
+7. Commit reviewed evidence and move the old passing current tuple to previous.
+8. Publish annotated gem tags only after the exact commit candidate is green and
+   the trusted publisher is configured. Publication never implies deployment.
+
+Commit pins are valid for an unpublished candidate, but the durable published
+state must record the annotated tag object and peeled commit. Tags or `latest`
+may be kept as human-readable provenance only; execution coordinates use full
+Git commits and `image@sha256:...` references.
+
+## Rollback
+
+Rollback restores the whole certified `previous` tuple. Do not roll back only
+the gem, only the consumer, or only the runtime image: the wire contract is the
+unit of compatibility.
+
+The deployment platform's immediately preceding application image is not
+automatically the certified OpenCode rollback. Keep it as emergency service
+provenance, but if it contains a client/runtime tuple known to fail the contract
+it must not occupy `previous`. In that case rollback means deploying the exact
+consumer commit and runtime coordinates recorded in the certified `previous`
+tuple, even if that is different from the platform's one-click rollback target.
+
+## Custom images
+
+Record each provenance layer separately:
+
+- consumer commit;
+- exact output registry digest or Docker image ID;
+- exact base image digest;
+- custom OpenCode source commit, when the base is a fork;
+- build-source commit when it differs from the deployment commit.
+
+The tuple fingerprint binds these values. On the next rebuild of an older
+unlabelled private image, add OCI labels for the custom OpenCode source, reported
+version, consumer build revision, and base digest, then make preflight compare
+the labels. Do not relabel an already certified image: that changes its digest.
+
+## Runner and forge contract
+
+Runner upgrades are a separate compatibility surface from OpenCode upgrades.
+Workflows must install their required Ruby/toolchain explicitly, declare Bash
+for scripts that use Bash syntax, and avoid relying on ambient runner packages.
+Browser suites must provision the reviewed Chrome/Selenium path explicitly;
+an absent browser is a runner failure, not product evidence. Keep a system-test
+suite serial when its harness shares an ephemeral server port instead of
+mistaking parallel `EADDRINUSE` failures for OpenCode regressions.
+
+GitHub and Gitea do not implement every Actions feature identically. Keep the
+same tests on both forges, but use forge-specific execution where necessary:
+GitHub retains review artifacts and parallel dynamic image jobs; Gitea runs the
+same manifest image set sequentially and makes no artifact-retention claim.
+Neither path may mutate a runner or deploy a consumer.
+
+A runner-only workflow repair needs exact-head CI, not an application canary.
+A client, runtime image, event, persistence, or toolchain change needs the
+profile and consumer canaries described above.
+
+For a frozen rollback snapshot that is no longer a merge candidate, provide a
+default-branch audit workflow that accepts and checks out an explicit full SHA.
+That lets current runner plumbing test the immutable old application tree
+without adding a CI-only commit to the rollback coordinate or pretending a
+known runner-workflow failure is an application incompatibility.
+
+## Expected breakages
+
+- Prompt submission before event subscription can miss a terminal event and
+  hang a turn.
+- An SSE parser that recognizes only `\n\n` can stall on CRLF, bare-CR,
+  byte-order-mark, comment, or multiline-data framing that is valid on the
+  wire.
+- Changes to terminal or message-part events can duplicate or lose final text.
+- Usage events can undercount multi-step requests if totals are overwritten.
+- Reconnect logic can replay a prompt and create duplicate model requests.
+- A Bun/Node server close can wait forever on idle keep-alive sockets unless
+  idle connections are explicitly reaped after admissions stop; the resulting
+  orphan can exhaust a service cgroup's PID budget and block a safe upgrade.
+- Asset builds can fail when runtime configuration is evaluated without the
+  image variables available only at deploy time.
+- A workflow can pass locally but fail under `sh` when it uses Bash arrays or
+  `mapfile`.
+- Plugin hook names, provider schema, config/MCP schema, or CLI flags can break
+  direct consumers even when the Ruby profile stays green.
+- `Opencode::Turn` is still an alpha-stage Rails composition seam; constructor,
+  observer, persistence, or finalization changes can break hosts even when the
+  lower-level Ruby wire client remains compatible.
+- A custom fork can silently lose its required ordering or permission patch if
+  only an opaque output digest is retained.
+
+When one of these changes, update the owning profile and consumer evidence. Do
+not weaken a strict invariant to make a new upstream release pass.
