## Thinking Path
- Paperclip Runner needs its runtime preinstalled for fast sandbox
startup.
- Native and local adapters should launch one current CLI installation
per provider.
- An older global copy can shadow that installation, and exact native
compatibility pins must match it.
- Update the qualified releases and binary digests, expose shared CLI
entrypoints from the provider pack, and prefer the image-owned bin
directory.
- Keep dependency installation in the image build; task startup only
discovers, links, and verifies artifacts.
## Linked Issues or Issue Description
**What happened?**
Remote native startup rejected a stale global Codex, while CLI-only
images lacked runnerd entirely.
**Expected behavior**
An image-baked runtime starts without uploading binaries or installing
packages. All adapters share the same current provider CLI.
**Steps to reproduce**
Start a native remote task with the old global Codex and the updated
runtime available only under `/opt/paperclip-runner/bin`.
**Paperclip version or commit**
Discovery behavior at `54a99d884`.
**Deployment mode**
Docker with a remote sandbox.
## What Changed
- Prefer `/opt/paperclip-runner/bin`, then the user's local bin
directory, then PATH. Existing metadata and version validation remains
in force.
- Qualify Codex 0.153.4, OpenCode 1.18.29, and Claude SDK 0.3.263 / CLI
2.1.263. Update binary digests, TypeScript/Rust checks, registry
defaults, and the displayed OpenCode version together.
- Share Codex and Claude's native executable with the ACP bridges
through exact dependency overrides. Preserve the separately qualified
ACP bridge implementations and their security patches.
- Expose shared provider-pack CLI launchers; fail the pack build if
Codex ACP resolves a separate Codex installation. Update the eval
image's other agent CLIs to current stable releases and remove duplicate
global provider installs.
- Document the single-current-CLI policy in source comments and
development guidance. Latest stable releases are resolved at
review/build preparation and pinned; task startup never auto-updates.
## Verification
- Native-session and adapter-registry suites: 158 tests passed.
- Provider suites: 88 tests passed, 7 Linux-only checks skipped on
macOS. One existing macOS temporary-path alias assertion passed when
rerun with canonical `TMPDIR=/private/tmp`.
- Package-contract and OpenCode materialization tests: 11 passed.
- Full typecheck, build, and token gates passed. Rust
native-provider/recovery tests: 19 passed.
- Broad local suite: 5,974 passed, 23 failed, 41 skipped. Failures are
in unchanged macOS workspace/path/port and connection suites; focused
runtime tests pass. All latest-head Linux PR checks passed, including
the full test shards, typecheck, build, runner verification, browser
suites, and canary dry run.
- The standalone fleet image built with one current provider CLI each
and passed native Codex/Claude binary-integrity checks. A disposable
Daytona sandbox reported ready in 798 ms; its baked runner completed an
API-key `gpt-5.6-luna` turn in 2,430 ms and returned the expected marker
with a usage receipt. No runtime artifacts were uploaded or installed.
- The normal shared `codex exec` entrypoint also completed an API-key
`gpt-5.6-luna` turn in 2,321 ms.
- Both image builds verify the complete generated lockfile against a
reviewed SHA-256 before package installation or lifecycle execution.
Root lockfile changes remain CI-owned. Merge and rollout remain on hold
for operator review.
## Risks
- Updating provider CLIs changes their behavior for all adapters;
version probes and live native smoke testing are required before image
promotion.
- The image-owned directory takes precedence. Its entries must launch
the same shared CLI as the global PATH, not a private older/newer copy.
- Application qualification pins and the deployed image must move
together. No startup fallback installation is added.
- No schema or authentication-policy changes.
## Model Used
OpenAI GPT-6 (Codex). The session does not expose a more specific model
ID or context-window size. Used reasoning, repository inspection, code
execution, and browser verification.
