Unreleased

[0.5.1] - 2026-08-10

Fixed

  • Make the published package loadable by any consumer. mix.exs required build_support/dependency_sources.exs, which the package does not ship, so mix compile in a consuming project died while Mix loaded this dependency's project. It now detects a source checkout by that file's presence: in a checkout the registry resolves siblings path-first as before, and in a published package the Hex requirements stated in mix.exs are the whole answer. 0.5.0 is retired.

[0.5.0] - 2026-08-10

Two provider profiles were written against event schemas their CLIs do not produce. Neither failed loudly; both simply reported that nothing happened.

Changed

  • The Antigravity profile now requests --output-format stream-json. It previously ran agy --print, whose plain-text output was normalized one line at a time into assistant deltas — so a run produced text and nothing else: no tool calls, no token usage, no terminal result. agy reports a run as numbered steps that go ACTIVE then DONE, which supplies both halves of a tool call. A stdout line that is not JSON is still emitted as an assistant delta, so output_format: "text" and older CLIs keep working.
  • Codex and Antigravity tool names and parameter keys are translated to the spellings consumers already use for other providers: a shell command is Bash carrying a command, a file edit is Edit carrying a file_path. Renderers and tool allowlists both key off these names, so a provider-specific spelling renders correctly while silently matching no allowlist entry.

Added

  • The Codex profile decodes the item types codex exec --json actually emits: command_execution, file_change, mcp_tool_call, web_search and todo_list. It previously looked for item types named tool_call and tool_result, which the CLI has never emitted, so every tool call fell through to :raw and no consumer could see that the model had done anything. The older names are still accepted.
  • item.started is decoded as tool_use, giving a live signal that a tool has begun rather than only that it finished. Both halves carry the item's id, which is what pairs a call with its result.

Fixed

  • turn.failed is decoded, emitting both an error and a terminal result. It was previously unmapped, so a failed Codex turn produced no stop reason at all and a consumer waiting on one waited indefinitely.
  • normalize_session_id/1 treated nil as an atom — which it is — and returned the string "nil". That value then overwrote the real provider session id on every event that did not carry one, so only the first event of a run held it. Every resume path reads that id back, and would have resumed a thread named "nil".
  • The local runtime gateway derived an error's ambiguous flag by comparing its category against :ambiguous, a value that category can never hold — the gateway resolves every outcome it reports. Error.new/1 enforces ambiguous == (category == "ambiguous"), so the flag is now stated directly.

Removed

  • Unreachable clauses in the runtime gateways, each proved dead by the type rather than by inspection: the clear_env? guard in both Local and RuntimeClient session-binding validation, since GovernedAuthority types that field as the literal true and enforces it in validate_clear_env/1; a non-map head of metadata_value/2 whose argument comes from a map-typed %Options{} field; and a third normalize_runtime_reply/1 head for a reply shape the runtime does not produce.

The package is Dialyzer- and Credo-clean with no ignore entries.

0.4.1 - 2026-07-27

Fixed

  • The Claude profile now emits --effort from the shared model registry's normalized model_payload.reasoning. Previously Claude effort was validated and preserved in the payload, then silently dropped by the direct CLI lane.

0.4.0 - 2026-07-27

Added

  • Total :structured_output and :completion_only feature manifests for all built-in providers plus ProviderFeatures.Error, whose provider, feature, option, and support state are pattern-matchable.
  • CliSubprocessCore.EphemeralFile, a provider-neutral exclusive 0600 temporary-file primitive with owner monitoring and idempotent bounded teardown.
  • Dependency-source helper v6 release edges from antigravity_cli_sdk and amp_sdk to cli_subprocess_core.

Changed

  • Amp and Antigravity now reject unsupported schema and completion-only intent before resolving or starting their CLIs. Ordinary invocations are unchanged.
  • OutputSchemaFile delegates secure materialization to the generic primitive while preserving its JSON validation and public error contract.
  • Amp result projection preserves provider result text, status/subtype, durations, turns, usage totals, cost, and permission denials. Antigravity keeps non-empty provider output byte-faithful.

Fixed

  • Removed redundant clauses diagnosed by Elixir 1.20 so the warnings-as-errors build remains green on the current release toolchain.
  • Keep the opaque transport-error matcher dynamically callable after a downstream function has excluded generic exceptions. This prevents Elixir 1.20 from over-refining valid facade calls to an always-false branch while preserving the lower transport struct boundary.

0.3.0 - 2026-07-27

Added

  • Payload.Result.object carries a provider-returned structured object. The Claude profile lifts structured_output off the result frame; the Codex profile decodes the schema-constrained final agent message, and only when the run actually requested a schema. A reply that is not JSON leaves the field nil rather than manufacturing an object. Amp, Cursor, and the synthetic exit result declare the field explicitly empty because no structured-output surface is proven for them.
  • CliSubprocessCore.OutputSchemaFile and CliSubprocessCore.EphemeralFiles: an owner-monitored lifecycle for temporary files an invocation needs on disk. ProviderProfile.build_invocation/1 may now return {:ok, invocation, teardown}; Command.run/1 and Session run that teardown on a normal result, an error, an interrupt, and a close, while EphemeralFiles removes the file when the owning process is killed untrappably and never gets to run it.
  • A completion-only invocation profile (completion_only: true). Claude receives an empty tool set, plan permission mode, no settings sources, and strict MCP config. Codex receives a read-only sandbox, ephemeral operation, no user config or rules, disabled web search and skills, and an approval_policy="never" config override. Both replace, rather than merge with, caller-supplied permission state.

Fixed

  • Publish preflight now requires the exact sibling version developed against to exist on Hex. An older package release can no longer mask a missing current release, as the historical execution_plane 0.1.0 monolith did for the core-only execution_plane 0.2.0. Nested package tasks resolve the helper-owning repository, and a manifest self-entry is not treated as a circular prerequisite.
  • --output-schema now receives a file path. codex exec types the flag as a path and exits non-zero when it cannot read the file, so the previous inline JSON encoding was a hard failure rather than a degraded mode.
  • transport_headless_timeout_ms reaches the transport. Without the alias the declared orphan-reap window was silently replaced by the transport's own 30 s default, letting a subprocess outlive its owner by 25 s longer than the contract allows.
  • Output-schema files use an OS-process-qualified, exclusive 0600 namespace, reject cross-owner tracking collisions, and are proven to disappear through every public command/session terminal path.

Changed

  • Require the core-only execution_plane ~> 0.2.0; the historical 0.1.0 Hex package bundled the same process and JSON-RPC modules now supplied by the canonical component dependencies.
  • Refreshed the zoi lock from 0.18.5 to 0.18.7.
  • The shared Claude catalog advertises Opus 5. Both opus and the retained compatibility choice opus[1m] list claude-opus-5; Opus 5 is itself a 1M-context model, so no suffixed provider id is invented. Prior full ids (claude-opus-4-8, claude-opus-4-7) remain resolvable, matching how the Sonnet entry retains claude-sonnet-4-6.

0.2.0 - 2026-07-13

Added

  • Current Codex GPT-5.6 Sol, Terra, and Luna catalog entries plus the public GPT-5.3-Codex-Spark ChatGPT Pro preview, including model-specific reasoning defaults and max/ultra validation.
  • Cursor Agent CLI (:cursor) first-party provider profile with stream-json parsing, live fixture evidence, model catalog entries, and provider feature metadata.
  • Documentation updates for Cursor as the fifth built-in profile, including invocation shape, permission metadata, governed posture, and capability hints.
  • Atom-safety guardrail: .credo.exs with Credo.Check.Warning.UnsafeToAtom enabled (scoped to lib/) plus a scripts/atom_guard.sh CI backstop wired into mix ci (which now runs credo --strict).
  • Secrets guardrail: scripts/secrets_guard.sh in mix ci; .env files gitignored.
  • README documents registry ownership and hex publish-ordering: this package publishes first, then claude_agent_sdk / agent_session_manager.

Changed

  • Restricted the Hex archive to runtime source, model data, dependency-source support, consumer guides/examples, and public release documentation/assets.
  • Replaced separate Execution Plane core, JSON-RPC, and process package dependencies with the single generated execution_plane ~> 0.1.0 package.
  • Local development now consumes the generated monolith artifact and clean clones fall back to the durable projection/execution_plane branch.
  • The Codex catalog now follows an authenticated live codex-cli 0.144.1 model/list probe from 2026-07-10: gpt-5.6-sol is the default, Spark is public but non-API, codex-auto-review remains internal, and backend-absent gpt-5.2 stays excluded.
  • Refreshed compatible dependencies, including Zoi 0.18.5.

Security

  • Command env validation returns offending keys (or :not_a_map) in {:invalid_env, ...} error tuples instead of echoing the full env map, whose values routinely include credentials.

Removed

  • Retired the Gemini CLI profile, catalog, discovery/fallback path, feature manifest, and model-selection workflow target. Google coding-agent support now uses the Antigravity profile only.

0.1.0 - 2026-04-06

Added

  • Initial release.
  • Governed CLI launch authority for command, cwd, env, config-root, auth-root, base-URL, target, and clear-env materialization without ambient provider CLI env discovery.
