What Changed

Add an internal relationship-only listing mode with bounded host reads. GitHub bypasses indexed search and avatars; Gitea, Bitbucket, and Azure walks stop after four raw pages. Missing rows and exhausted budgets remain partial. Gitea uses verified branch labels, rejects retained refs as live sources, and checks target identity, repository IDs, counts, and duplicates.

Why

Dependency discovery must inspect an unfiltered repository collection without loading reviews or silently treating incomplete pages as complete. Gitea cases follow the companion fork handoff and captured response projections.

Stack step 2/7. Builds on #24.

Validation: focused tests and scoped lint passed for the implementation and review fixes, including 56 Gitea API, 15 topology, 113 service, and 11 navigation tests after the latest changes. Contracts, client-runtime, and web typechecks passed. Server typechecking reports eight Gitea errors, all reproduced on pristine parent 85dd52877, with no new errors.

The captured Gitea three-PR response produces two confirmed edges through the implemented adapter and graph. The handoff’s live instance was unreachable during this run.

Checklist

  • One focused review slice
  • Explained the problem and resulting behavior

Models and harnesses: GPT-5.6 Sol (high) and Codex; identity groundwork by GPT-5.6 Luna (max).

📝 Walkthrough

Walkthrough

The pull-request providers now support relationship-only discovery. Implementations use bounded pagination, preserve cursor progress, detect incomplete relationship evidence, and skip unrelated decorations. Shared contracts expose branch availability and native dependency membership.

Changes

Relationship-only pull-request discovery

Layer / File(s) Summary
Provider contracts
apps/server/src/pullRequest/PullRequestProvider.ts
Adds relationship-only listing inputs, head-branch availability, and optional native dependency membership retrieval.
Azure DevOps bounded listing
apps/server/src/pullRequest/AzureDevOpsPullRequestCli.ts, apps/server/src/pullRequest/AzureDevOpsPullRequestProvider.ts, apps/server/src/pullRequest/AzureDevOpsPullRequestCli.test.ts
Forwards relationship-only requests, caps discovery at four pages, advances the cursor across raw rows, and reports truncation.
Bitbucket bounded listing
apps/server/src/pullRequest/BitbucketPullRequestApi.ts, apps/server/src/pullRequest/BitbucketPullRequestProvider.ts, apps/server/src/pullRequest/BitbucketPullRequestApi.test.ts
Tracks incomplete pages caused by invalid rows, uses a four-page relationship-only cap, and preserves truncated results.
GitHub bounded listing
apps/server/src/pullRequest/GitHubPullRequestCli.ts, apps/server/src/pullRequest/GitHubPullRequestProvider.ts, apps/server/src/pullRequest/GitHubPullRequestCli.test.ts, apps/server/src/pullRequest/GitHubPullRequestProvider.test.ts
Uses bounded repository listing without search expansion or avatar lookup. Invalid or filtered rows produce truncated results.
Gitea relationship evidence
apps/server/src/pullRequest/GiteaPullRequestApi.ts, apps/server/src/pullRequest/GiteaPullRequestProvider.ts, apps/server/src/pullRequest/GiteaPullRequestApi.test.ts
Adds branch and repository metadata, validates relationship evidence, deduplicates results, bounds pagination, and reports incomplete coverage.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to 3ccc8

Relationship-only repository discovery now uses bounded provider reads and reports incomplete results where evidence is partial. Query-bearing Gitea requests retain this bounded behavior, leaving no current merge-blocking risk.

1003-1005: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep relationship-only requests out of search pagination.

When both query and relationshipOnly are set, this branch enters listSearchPullRequests before relationship-only mode is evaluated. That helper can read up to 100 pages and hydrate each row. It also raises the normal pagination-limit error instead of returning a partial relationship result.

Route relationship-only input through the four-page bounded listing, or reject this unsupported input combination at the API boundary.

@coderabbitai review

Please review the latest head after the verified findings were fixed and the stack was rebased. The focused fixes passed 296 tests and targeted lint; web typechecking passed. Server typechecking matches the eight errors on the pristine Gitea parent, with no new errors.

The outside-diff query finding is fixed too: relationshipOnly takes precedence over query and stays on the bounded unfiltered /pulls path, with a regression that verifies no issue-search hydration.

365-367: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add x-total-count so this test isolates the skipped row.

The response omits x-total-count. In relationship-only mode a missing total count already sets the incomplete flag, so truncated is true regardless of the malformed row. This test passes even if the decode-failure branch stops marking evidence incomplete.

Set a consistent total count. The only remaining cause of truncation is then the skipped row.
