## Summary
- choose the local OpenAI curated marketplace manifest based on auth:
Codex backend auth gets the existing marketplace, direct provider auth
gets `api_marketplace.json`
- include Bedrock API key auth in the direct-provider API marketplace
path
- safely skip the API marketplace when `api_marketplace.json` is absent
## Validation
- `just fmt`
- `git diff --check origin/main...HEAD`
- CI should run the full validation
## Manual Testing
### - New api marketplace not available for API key sign
1. Safely not display anything from api marketplace

/>
### - New api marketplace for API key sign in
1. Setup api_marketplace.json
```
{
"name": "openai-curated",
"interface": {
"displayName": "Codex official"
},
"plugins": [
{
"name": "linear",
"source": {
"source": "local",
"path": "./plugins/linear"
},
"policy": {
"installation": "AVAILABLE",
"authentication": "ON_INSTALL"
},
"category": "Productivity"
}
]
}
```
2. Log in with API key, observe that only the defined plugin from
api_marketplace.json is available from "Codex Official" (outside of
local testing marketplaces)

### - SiWC users
Still uses 'default' marketplace.json and renders all plugins

## Notes
- `just test -p codex-core-plugins` was started locally before splitting
branches, but I stopped relying on local tests per follow-up and left
final validation to PR CI.
# Summary
Reduce download traffic to `github.com/openai/plugins` while continuing
to check for updates on every Codex startup.
# Root cause
The startup sync replaced the local repository with a fresh shallow
clone whenever the remote revision changed. At Codex's global scale,
repeatedly downloading the repository created excessive GitHub traffic.
# Changes
- Run `git ls-remote` on each startup to read the remote HEAD SHA.
- Skip all repository downloads when the local and remote SHAs match.
- Update existing checkouts with an exact-SHA shallow `git fetch`,
followed by reset and clean.
- Bootstrap new installations with `git init` plus the same shallow
fetch, rather than cloning.
- Keep the existing file lock so concurrent Codex processes serialize
updates and do not duplicate fetches.
- Preserve the existing GitHub HTTP and export archive fallback
behavior.
# Impact
Each startup makes one lightweight remote HEAD check. Repository objects
are downloaded only when the revision changes, and existing Git objects
are reused during updates.
# Validation
- `just test -p codex-core-plugins startup_sync` (15 tests passed)
- `just test -p codex-core-plugins` (201 tests passed)
- `just clippy -p codex-core-plugins` (passes with one pre-existing
`large_enum_variant` warning)
- Production app-server smoke test against GitHub:
- Fresh home: `ls-remote`, `git init`, one exact-SHA shallow fetch
- Unchanged restart: `ls-remote` and local `rev-parse` only; no fetch or
clone
- Bench smoke passed
