📝 WalkthroughWalkthroughThe PR adds dynamic pull request reviewer configuration. Expressions select users or groups, controllers propagate desired reviewers, and SCM providers add or remove review requests. API schemas, validation, tests, metrics, and documentation are updated. ChangesDynamic pull request reviewers
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The reviewer test package does not compile, so the change should be corrected before merge. Reviewer-removal errors and retry semantics otherwise behave as intended. Sequence Diagram(s)sequenceDiagram

In `@api/v1alpha1/pullrequest_types.go`:
- Line 96: Update the lifecycle comment for status.appliedReviewers to state
that reviewers are added or removed to match spec.reviewers, rather than
claiming they are only ever added.
In `@api/view/v1alpha1/zz_generated.openapi.go`:
- Line 4230: Update the OpenAPI description for PullRequest.spec.reviewers to
remove the claim that reviewers are only ever added; describe the field as the
desired reviewer set, with removals reflected through the controller and
status.appliedReviewers.
In `@internal/controller/testdata/PullRequest.yaml`:
- Around line 52-53: Update the comment describing appliedReviewers to state
that the controller may withdraw pending review requests for reviewers removed
from spec.reviewers and update status.appliedReviewers; remove the inaccurate
claim that the collection only grows while the pull request is open.
In `@internal/scms/github/pullrequest.go`:
- Around line 433-435: Update the reviewer-removal handling in
reconcileReviewers so HTTP 404 and 422 responses are not treated as successful
removal; return the underlying error for those statuses unless a successful
response or explicit state check confirms the review request is absent. Preserve
nil returns only for confirmed successful removal and prevent AppliedReviewers
from being updated after an unconfirmed failure.

@sahil-sharma since we're still evaluating whether the feature is a good cost/benefit tradeoff, would you mind asking the robots to try to implement the other SCMs? No need to commit it to this branch if you don't want. It would just be nice to see if there are any gotchas lurking in the other SCMs that would be helpful to know about before we make a go/no-go decision. |

Sure. I will give it a shot and see what our AI friends have to say on this. BTW "asking robots" was a good crack. 😂 |

Part of #1881
Adds
pullRequest.reviewerstoPromotionStrategy, so promotion PRs open with reviewers already requested. Expression-based, mirroringpullRequest.labels.A bare string means
{user: <name>}.{group: <name>}is an org team on GitHub.The flow follows labels: the CTP controller evaluates the expression into
PullRequest.spec.reviewers, and the PullRequest controller diffs againststatus.appliedReviewersto add or remove. Newinternal/reviewerspackage mirrorsinternal/labels.Implemented for GitHub only. The other providers return a clear error when reviewers are configured.
Reviewers are applied on the reconcile after the PR is created, because
createPullRequestreturns early and the reviewer step needsstatus.id.Not verified against a live GitHub repo — envtest covers the fake provider only.
