 # Changelog
 
+## 0.1.43 - 2026-09-04
+
+MendCode v0.1.43 adds the current OpenAI GPT-5.6 family and GPT-6 Astra to
+the model and Codex OAuth surfaces while keeping the terminal session view
+compact during concurrent work.
+
+### Changed
+
+- Add GPT-6 Astra plus GPT-5.6 Sol, Terra, and Luna API and ChatGPT OAuth
+  presets with documented limits, pricing, reasoning levels, and fast/pro
+  variants where the provider exposes them.
+- Keep the OpenAI model picker populated from an in-process fallback when a
+  cached or bundled `models.dev` catalog predates the current model family;
+  live provider metadata still takes precedence.
+- Keep Commands history in the Ctrl+T horizontal widget tray with a direct
+  action to open the originating session.
+- Record the Codex CLI `0.153.3` comparison and the compatibility decisions in
+  the release audit.
+
+### Fixed
+
+- Allow GPT-6 Astra through the ChatGPT OAuth model filter with its documented
+  context and input limits while retaining the existing Responses Lite scope
+  for GPT-5.6 tiers.
+
+### Tests
+
+- Add model-catalog fallback, model-preset, Astra OAuth filtering, mode
+  normalization, and context-limit regressions.
+
 ## 0.1.42 - 2026-09-03
 
 MendCode v0.1.42 makes queued prompts, cancellation, reconnection, and communication between sessions reliable under concurrent work.

+# Codex CLI and OpenAI model audit — 2026-09-04
+
+This audit records the upstream Codex CLI comparison used for the 0.1.43
+release. The reference CLI stable release was `0.153.3` (`rust-v0.153.3`).
+OpenAI's current model pages identify the flagship model as `gpt-6-astra` and
+the 5.6 family as `gpt-5.6`/Sol, Terra, and Luna.
+
+## Ported in 0.1.43
+
+- Add `gpt-6-astra`, `gpt-5.6`, `gpt-5.6-sol`, `gpt-5.6-terra`, and
+  `gpt-5.6-luna` to the OpenAI catalog fallback. A stale cache or bundled
+  `models.dev` snapshot no longer hides these models from the picker.
+- Preserve live `models.dev` entries when they exist, so the fallback cannot
+  replace newer provider metadata.
+- Add API and ChatGPT OAuth presets with documented context limits and API
+  prices. GPT-6 Astra keeps its 1.05M context/922K input limit; ChatGPT OAuth
+  Sol, Terra, and Luna keep the existing 256K effective limit imposed by the
+  Responses Lite adapter.
+- Recognize Astra and its documented `fast` variant in the ChatGPT OAuth
+  catalog. Astra stays on the standard Codex Responses transport; the current
+  MendCode Responses Lite compatibility contract is limited to the 5.6 tiers.
+- Keep the compact Commands history in the Ctrl+T horizontal widget tray,
+  including its direct session-open action.
+
+## Reviewed and intentionally not ported
+
+- Upstream's asynchronous model-picker refresh (`5fc7840cf6d0`) is a larger
+  TUI/server contract change. MendCode already refreshes `models.dev` in the
+  provider service; this release adds the static safety net without changing
+  picker lifecycle or selection state.
+- Luna Reserve usage fallback, app-server collaboration-mode discovery, live
+  context-compaction status, rate-limit banners, permission-profile discovery,
+  startup warning condensation, automatic thread naming, and submission-ID
+  steer acknowledgement were reviewed from the upstream history. Each needs a
+  separate MendCode contract and regression surface, so none is represented as
+  shipped behavior here.
+- The upstream CLI version is not copied into MendCode's `version` request
+  header. The existing `0.144.0` value belongs to MendCode's internal
+  Responses Lite compatibility contract, and the upstream source contains no
+  equivalent current header contract to justify changing it.
