DottaandPaperclip 35c75b56d4 fix(pi): credit Paperclip for default legacy OpenRouter requests (#16864)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Legacy adapters can use host credentials and provider settings.
> - OpenRouter assigns app credit from the final request headers.
> - The first attribution change covered managed connections and
explicit provider configs.
> - Legacy Pi with only an API key bypassed those config changes.
> - This pull request applies attribution at Pi's request boundary.
> - The benefit is Paperclip credit without replacing the user's Pi
home.

## Linked Issues or Issue Description

Follow-up to #16850. A search of related OpenRouter PRs and issues found
no duplicate fix for this path.

**What happened?**

A legacy `pi_local` agent with `OPENROUTER_API_KEY` and no
`PAPERCLIP_PI_PROVIDERS` could send requests without Paperclip
attribution. Existing Pi home configs could also retain the previous
harness title.

**Expected behavior**

Paperclip receives credit for OpenRouter requests from its legacy Pi
adapter. The adapter preserves credentials, routing, model settings, and
other providers.

**Steps to reproduce**

1. Configure a legacy Pi agent with an OpenRouter model and API key.
2. Leave `PAPERCLIP_PI_PROVIDERS` unset.
3. Start a run and inspect its outgoing headers or OpenRouter generation
record.

**Paperclip version or commit**

Reproduced after #16850, on master commit
`9179d8dcc3e908c217fde4f63c9d08ccf8132eeb`.

## What Changed

- Load a temporary attribution extension for every legacy Pi run,
including remote targets and retries.
- Apply headers after credential and model-header resolution on Pi 0.74
and at provider dispatch on Pi 1.0.
- Check the actual endpoint. Cover custom aliases and regional
OpenRouter hosts. Preserve other endpoints, credentials, unrelated
headers, and explicit visibility preferences.
- Keep the Pi home, auth file, settings, and model catalog in place.
Remove the temporary extension after the run.
- Prevent repeated wrapping when Pi recomposes a provider after a
registry refresh. Add regression tests and update the connector
playbook.

## Verification

- Final head `902399468a9033d12e3ff6ab30c8463daef50bad`: Greptile
**5/5**, with no actionable comments. CI is waiting for runner
assignment.
- Complete legacy Pi adapter suite: **124 tests passed across 12
files**, including extension, runtime-config, and remote execution
coverage. The initial focused subset passed 30 tests.
- `pnpm -r typecheck` and `pnpm build` passed. After the lifecycle
guard, all 124 Pi tests and the Pi package typecheck passed again. Full
`pnpm test:run` is in progress.
- Actual Pi 0.74 outgoing-request comparison with dummy credentials: the
baseline sent no attribution headers. The patched request sent all four
Paperclip headers and retained the same credential. The transport
returned an intentional 401 after capture; this check does not claim
successful inference.
- Final-head Pi 0.74 request-capture matrix: **8/8 passed**. Cases cover
bare keys, host aliases, per-model overrides, EU/US endpoints, a
repointed built-in provider, an unrelated provider, and an HTTP
endpoint. Credentials, custom routing headers, and visibility
preferences survived. These captures used dummy credentials and
intentional 401 responses.
- Live request through the actual legacy adapter with Pi 0.74: response
`legacy attribution verified.`; generation
`gen-1792424885-G3THa6DdJXmAL3C841DI`; OpenRouter app ID **3118063**;
cost **$0.0002268**.
- Live request through the actual legacy adapter with the Pi 1.0 bundled
CLI: response `legacy attribution verified.`; generation
`gen-1792425530-LlpIbfBFyjs6XRP5l5PV` on final head
`902399468a9033d12e3ff6ab30c8463daef50bad`; OpenRouter app ID
**3118063**; cost **$0.0002391**. Its usage record became available on a
later read.
- Both live runs preserved the existing `models.json`, `settings.json`,
and `auth.json` byte for byte. Pi 0.74 also retained the custom
`X-Route` header while replacing the conflicting harness title.
- Built-package smoke passed. `npm pack --dry-run --ignore-scripts`
includes `dist/server/openrouter-extension.js`, and the compiled helper
produced a working self-contained extension. The pack check used a
temporary npm cache because the default cache was not writable.
- Remote asset delivery is covered through the SSH execution test
boundary. No live remote sandbox was used.
- Initial capture attempts produced no requests because the test left
stdin open. A separate source-checkout live attempt lacked the
TypeScript loader and did not reach the provider. Correcting the test
setup produced the evidence above. Pi 1.0's bundled transport bypassed
the global-fetch capture shim; its acceptance evidence is the successful
live request and provider-side app ID.

## Risks

- The extension depends on Pi 0.74's request-auth registry and Pi 1.0's
provider API. Harness upgrades require a fresh request capture or live
credit check.
- Missing extension delivery stops remote startup rather than silently
losing attribution.
- A private gateway that replaces headers and an externally managed
harness remain outside this adapter's control. Public listing metadata
still belongs to OpenRouter.
- No database, API, credential ownership, or telemetry contract changes
are required.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository editing, shell
execution, and live API verification. The exact runtime model identifier
and context-window size are not exposed in this session.
