fix(server): opening a pull request loads while its host is rate-limited - #27595
When a source control host is paused after a 429 (SourceControlRateLimit), opening one of its pull requests in the pull request panel fails with … requests to bitbucket.org are paused until the rate limit resets. and no request is sent. withRateLimitBackoff treats getChangeRequest, getChangeRequestActivity and the other reads as background reads and also overwrites the caller's SourceControlRateLimit.Interactive with false. So the panel can't get through the pause, even though https://git.cafe/pingdotgg/t3code/pulls/23889 lets reads a user is waiting on go out during it. Reproduced on main with a local Bitbucket stub that answers 429 (transcript below).
Change
withRateLimitBackoff now honours a caller-provided SourceControlRateLimit.Interactive. A read whose caller marked it interactive skips the pause and passes the flag on to the provider. It no longer resets the flag to false. Methods that were already always interactive (writes, getViewerPermissions, …) are unchanged.
ws.ts marks only the pullRequests.detail and pullRequests.activity handlers interactive, the same way GitManager marks user actions. These are the reads that make up an opened pull request.
Summary, list, preview, stack and checks reads, and the server's own background callers of detail (the PR watch reactor, review guides), still fail at once during a pause. So the sidebar and startup sweeps can't restart the 429 flood from https://git.cafe/pingdotgg/t3code/issues/17799.
Red test opening a pull request during a rate-limit pause still reads its detail and activity in apps/server/src/pullRequest/PullRequestService.test.ts:
It fails on main: both reads return PullRequestOperationError with "github requests to github.com are paused until the rate limit resets".
It passes with the fix, and a background detail read during the same pause still fails.
PullRequestService.test.ts 108/108. vp run check:changed passes (format, lint, knip, typecheck for 3 packages, 118 tests).
Runtime transcript through the real WebSocket RPC, before and after:
Each side is a fresh dev server from its own checkout (T3CODE_DEV_SEED=0 T3CODE_BITBUCKET_API_BASE_URL=http://127.0.0.1:<stub>/2.0 T3CODE_BITBUCKET_ACCESS_TOKEN=synthetic vp run dev:server), with a synthetic project whose origin is https://bitbucket.org/acme/web.git.
a real Bitbucket Cloud or GitHub host under a real rate limit: the host was a local stub;
the client panel itself: no client code changed, and the RPCs it calls are the ones shown above.

…ate-limit pause
These tests reproduce #27579: once a host is paused for a rate limit,
PullRequestService.detail and .activity fail before any request goes out,
even when the caller marks the read as interactive with
SourceControlRateLimit.Interactive.

Once a host was paused after a 429, the pull request panel's detail and
activity reads failed before any request went out, because the provider
wrapper overwrote the caller's SourceControlRateLimit.Interactive with
false. The wrapper now honours a caller-marked interactive read, and the
pullRequests.detail and pullRequests.activity RPC handlers mark their
reads interactive. Bulk sidebar and list reads and background callers
keep failing fast during a pause.

Macroscope's review found this PR approvable — Opened pull-request details and activity can load through the existing interactive-request path during background rate-limit pauses. Background throttling and provider quota controls remain in place.

Walkthrough
Pull-request detail and activity reads now use the interactive rate-limit setting. A regression test checks that these reads succeed during a host pause while a background detail read remains blocked.
The rate-limit guard combines the current Interactive service value with the alwaysInteractive option. The WebSocket detail and activity handlers provide Interactive=true.
WebSocket reads and regression test apps/server/src/ws.ts, apps/server/src/pullRequest/PullRequestService.test.ts
The regression test checks that background detail reads fail, while interactive detail and activity reads succeed during a rate-limit pause.
No new merge-blocking issue is established for the pull-request loading change. The previously reported WebSocket test gap remains a follow-up.

Explanation
Issue #27579 requires an opened pull request to load while its host is rate-limited. withRateLimitBackoff now preserves caller-provided SourceControlRateLimit.Interactive and allows that read during the pause. ws.ts marks pullRequests.detail and pullRequests.activity interactive. Other pull-request reads remain background reads. The added test covers successful interactive reads and a failed background detail read during the same pause. This satisfies the linked issue's coding and test requirements.
Full details: Out of Scope Changes check
Explanation
The changed files stay within the issue scope. PullRequestService.ts changes the shared rate-limit wrapper required for the fix. ws.ts marks only the two RPC reads used to open a pull request as interactive. PullRequestService.test.ts adds regression coverage. No unrelated change appears in the reviewed change summary.

Cover the WebSocket caller boundary for this regression.
The test provides SourceControlRateLimit.Interactive directly to the service. Removing the WebSocket wrapper would therefore leave the test passing. Existing client tests stub these RPC methods and do not execute apps/server/src/ws.ts. Add a focused server caller-boundary test for pullRequests.detail and pullRequests.activity.

A question about how often the new interactive bypass fires.
In packages/client-runtime/src/state/pullRequests.ts, the detail and activity query atoms set refreshTrigger: ({ environmentId }) => refreshes(...), which is the pullRequestsSubscribeRefreshes turn-refresh stream, and writableQueryFamily keeps them around with Atom.setIdleTTL(5 * 60_000). With this change ws.ts wraps every pullRequests.detail and pullRequests.activity RPC in openedPullRequestRead. So those trigger-driven refetches also go through the pause, not just the read when the user opens the PR.
On Bitbucket that's the 5-request detail read (pull request, diffstat, conflicts, statuses, permission) plus the activity reads. They'd run for each open PR panel, on every client, every time a turn finishes in that environment, while the host is meant to be paused. If any of them gets a 429, recordRateLimit pushes the pause out again.
Is that intended? If not, one option would be to mark only first loads and explicit user refreshes as interactive, e.g. with a flag on the RPC input that ws.ts checks. Trigger-driven refreshes would then respect the pause and keep showing the cached value, which writableQueryFamily already does through failureWithPrevious.
Trigger HTTP 429 with Retry-After: 600 by opening synthetic Bitbucket PR 1, then open uncached PR 2 during the pause. Same Chromium viewport (1280×800), light theme, fresh synthetic data, and local host stub on both sides. Base blocks PR 2 before contacting the host; head loads its description and activity.
