Changelog

0.0.1.alpha3 - 2026-07-10

Bumped

• Runtime dependency opencode-ruby pinned to = 0.0.1.alpha3, exposing the session permission PATCH primitive to Rails host applications while leaving reconciliation policy in each host.

0.0.1.alpha2 — 2026-05-20

Changed

• Opencode::Exchange now emits opencode.apply_patch.artifacts_dropped via the new Opencode::Instrumentation.notify fire-and-forget API (introduced in opencode-ruby v0.0.1.alpha2) instead of .instrument(name, payload) { } with an empty block. Cleaner read at the call site; identical semantics on the wire (same event name, same payload).

Bumped

• Runtime dependency opencode-ruby pinned to = 0.0.1.alpha2 (was = 0.0.1.alpha1). Versions stay in lockstep during alpha.

0.0.1.alpha1 — 2026-05-20

Initial public alpha. Extracted from a production Rails app where these objects shipped as in-tree library code before being carved out into a standalone gem.

Includes:

• Opencode::Session — AR-coupled, row-level-locked session lifecycle (ensure!, recreate!, abort!)
• Opencode::Turn — orchestrator covering send → stream → recover → finalize, with CAS-safe message terminal-state transitions
• Opencode::Exchange — domain object over a turn's message array; emits opencode.apply_patch.artifacts_dropped when post-write file content is unavailable
• Opencode::Artifact — value-object (filename + content + content_type + trust metadata), idempotent attach
• Opencode::MessageArtifacts — ActiveStorage-aware artifact attachment pipeline with transform support
• Opencode::Sandbox — disk-backed sandbox reader, returns Artifact list
• Opencode::SandboxFile — single-file value object (pathname → bytes/content-type)
• Opencode::Transform — base class for content-rewriting transforms
• Opencode::Impostor — ActiveStorage download/upload round-trip helper
• Opencode::UploadedFilesPrompt — user-prompt prefix builder listing uploaded files, sandbox-path inverted (injection-based, no Opencode::Permissions reference)
• Opencode::ToolDisplay — view-model for tool-call hashes (Turbo Stream-friendly)
• Opencode::ErrorReporter — pluggable adapter mirroring the Opencode::Instrumentation pattern

Runtime dependencies:

• opencode-ruby ~> 0.0.1.alpha1 (wire client + Reply state machine)
• activerecord >= 7.1, < 9.0
• activestorage >= 7.1, < 9.0
• activesupport >= 7.1, < 9.0

Known limitations (alpha):

• Apply-patch tool's post-write file content is not extracted (wire-format limitation in OpenCode v1.15+); affected files surface via the opencode.apply_patch.artifacts_dropped instrumentation event. Future work: optional sandbox-read fallback path.
• Smoke tests only inside the gem. Behavioral coverage currently lives in the host app that produced this code. A standalone gem-side test suite using Combustion is open work.
• No generator (rails g opencode:install) yet.
• No Rails Engine integration — require "opencode-rails" is sufficient.
