## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents run on coding harnesses. Each adapter has a model catalog,
and sandboxes contain pinned CLIs.
> - Upstream providers released new CLI versions and new models. OpenAI
retired some Codex models for ChatGPT sign-in.
> - A stale catalog hides valid models. A misleading error makes
operators upgrade a CLI that is already current.
> - This pull request adds verified OpenCode model IDs, names Codex
ChatGPT retirements in the environment Test, and refreshes the sandbox
CLI pins.
> - The benefit is that operators can select current models and get the
correct reason when a retired model fails.
## Linked Issues or Issue Description
Refs #16708 (adds Claude Haiku 5.5 to `claude_local`; this PR does not
duplicate it).
Refs #17245 (moves the Codex runtime to 0.163.0; this PR does not change
Codex pins).
**What happened?**
OpenAI retired `gpt-5.5` (October 14, 2026) and `gpt-5.4` /
`gpt-5.4-mini` (August 31, 2026) from Codex with ChatGPT sign-in. A
saved agent with one of these models and ChatGPT sign-in now fails. The
legacy environment Test says that the plan, the rollout, or an old CLI
can be the cause. The Paperclip Runner Test gives generic account and
runtime advice. The real cause is the retirement.
**Expected behavior**
Both Tests give the retirement date and the documented replacement.
API-key users keep the models.
**Proposed change**
Record the verified retirements. Add the new verified OpenCode IDs.
Refresh the sandbox CLI pins with verified digests. Record the audit.
## What Changed
- Codex: add a table of models retired from Codex with ChatGPT sign-in
(`gpt-5.5` → `gpt-6.1-sol`, or `gpt-6-luna` on Free and Go; `gpt-5.4` →
`gpt-6-sol`; `gpt-5.4-mini` → `gpt-6-luna`). The shared
`codexChatGptRetirementHint` builds the hint. The legacy CLI Test
(`codexHelloProbeModelRejectionCheck`) and the Paperclip Runner Test
(`testNativeRunnerAuthentication`) both use it when the backend rejects
one of these models. For other failures, the Paperclip Runner Test hint
stays the same. The picker keeps the models for API-key users.
- OpenCode: add `anthropic/claude-haiku-5-5` and `google/gemini-4-argon`
to the remote fallback catalog. The Paperclip Runner OpenCode picker
also uses this catalog.
- Evaluation image sandbox layer (`docker/daytona-runner`):
| CLI | Before | After |
| --- | --- | --- |
| Grok CLI | 1.0.46 | 1.0.70 |
| Gemini CLI | 0.62.0 | 0.65.0 |
| Kimi Code | 2.1.1 | 2.3.3 |
| Cursor CLI | 2026.10.01-e373342 | 2026.10.22-27dcf5f |
| GitHub CLI | 2.102.0 | 2.103.3 |
- Add `doc/adapter-model-audit-2026-10-23.md` with sources,
compatibility findings, and deferred items.
No model in this PR needs a newer Codex, Claude, or OpenCode runtime
than the current pins. Claude Haiku 5.5 needs Claude Code 2.1.293 or
later; #16708 records that floor, and this PR does not add it.
## Verification
- `vitest run src/index.test.ts src/server/test.remote.test.ts
src/server/acp.cli-version.test.ts` in `packages/adapters/codex-local`:
41 passed.
- `vitest run src/services/native-runtime/setup-readiness.test.ts` in
`server`: 98 passed. These include the two new Paperclip Runner Test
cases: a retired model shows the retirement hint, and a model that is
not retired keeps the generic hint. The retirement case fails on the
earlier code. Run with the host's empty `ANTHROPIC_BASE_URL` unset; see
the baseline note in the audit doc.
- `vitest run` in `packages/adapters/opencode-local`: 87 passed.
- `vitest run src/__tests__/adapter-models.test.ts` in `server`: 27
passed.
- `tsc --noEmit` in `packages/adapters/codex-local` and
`packages/adapters/opencode-local`: passed.
- Cursor archive SHA-256
`85296944e4600a83c4b764f578d1502bf9c416db200d33a593e8f3ecabfdc294` is
computed from the versioned Linux x64 tarball. The extracted binary
reports `2026.10.22-27dcf5f`. On October 26, 2026,
`https://cursor.com/install` still resolves this version.
- GitHub CLI SHA-256
`4c806978ffce1cec70853302a56d70ac6da4f19bae7adca4e1a8ab00633dd91d`
matches `gh_2.103.3_checksums.txt`.
- Grok CLI 1.0.70 and Kimi Code 2.3.3 installed from npm report those
versions. The flags that Paperclip uses (`-m`, `--effort`, `grok
models`; `-m`, `-p`, `--output-format`, `acp`) are present in `--help`.
- `git merge-tree` with #16708 (head `3a06740e9`) and #17245 (head
`41f9c611f`): this PR shares no files with either PR. The two PRs can
merge in any order.
- Not run in the authoring environment: the full `pnpm -r typecheck` and
`pnpm build` (no Rust toolchain), the full server `tsc` (memory limit),
and the image build. CI runs these.
## Risks
- Low risk for catalogs: the IDs are additive suggestions. No saved
selection, default, or spending setting changes.
- The Paperclip Runner Test changes only the hint text, and only for a
ChatGPT rejection of a retired model. Check codes and pass/fail results
do not change.
- Sandbox CLI pins:
- Kimi Code 2.2.0 and 2.3.0 remove the `kaos` MCP executor and require
qualified plugin skill names. Paperclip uses neither. Kimi Code 2.3.2
stops automatic swarms in `kimi -p` and ACP sessions.
- Gemini CLI 0.65.0 makes workspace settings read-only in untrusted
folders. Paperclip writes home settings and sets
`GEMINI_CLI_TRUST_WORKSPACE` for remote runs.
- xAI publishes no Grok CLI changelog. Grok 1.0.70 behavior changes are
verified only against the CLI reference and `--help`.
- The pins apply only after a new image is built and promoted. The fleet
sandbox image definition must get the same pins.
- Rollback: revert this PR.
## Model Used
- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, with tool use (shell,
web research, repository search).
