Update derive_series_segments in app/lib/presenters/concerns/ai_segment_concerns.rb to enforce an ascending sort of cohort series by usage (Least use → Most use). Multiple additions and small updates replace the prior ordering behavior so series are calculated and ordered deterministically. Impact: cohort charts now consistently present segments from least- to most-used, improving readability and analysis.

Update vendor/gems/gitclear_teams/app/models/team_repo.rb (ensure_cached_stat_rebuild_on_create_destroy) to enqueue a build of LLM usage metrics when a Team is created and may have LlmUsageMetrics. This schedules metric generation asynchronously on create (consistent with destroy handling), preventing missed initial LLM stats and improving accuracy of LLM usage reporting.

Return audit PRs based on the most-recent "merged_at" value when a closed-date filter is provided, and add new audit fields (business_minutes_awaited_first_review, business_minutes_cycle_time, business_minutes_lead_time, business_minutes_open_to_closed, first_commented_at, first_commit_authored_at, post_merge_delta, squash_commit_sha). Changes touch V1::AuditsController and PullRequestConcerns::PullRequestJsonConcerns so API audit responses and closed-date queries are more accurate for report...

Adjust app/jobs/assign_pull_request_post_merge_commit_work.rb to search for and handle commit-message lines that indicate updates to squashed PR commits, with a small test tweak in test/unit/pull_request_post_merge_commit_test.rb. This fixes the failing test and ensures post-merge commit assignment correctly recognizes squashed-PR update lines so ownership is assigned reliably.

Return early from RepoImportProgress#calculate_percent_complete (app/models/repo_import_progress.rb) when the default branch has been processed as far back as the repository's processing epoch. This prevents unnecessary scanning/aggregation, fixes potential over-reporting, and reduces CPU/I/O during import progress calculation for more efficient, correct percent reporting.

Add an early-out to RepoImportProgress#calculate_percent_complete (app/models/repo_import_progress.rb) so that if the default branch has been processed as far back as the repository's provider_created_at the calculation returns immediately. This avoids scanning older history, prevents overcounting and wasted work, and improves import progress accuracy and performance.

Replace timeOffHtml with a timeOffArray: move derive_time_off_array out of vendor/gems/commit_activity_browser/app/lib/bubble_committer_concern.rb into app/javascript/bundles/cab-viewer/cab-committers-frame.js and update committer tooltip/content to consume the array. Prevents HTML-escaping problems in CAB and ensures correct time-off rendering.

Fixes a bug where the PR comment fallback time used 30.seconds without dividing by 1.minute, producing implausible minute estimates that propagated to PullRequestReviewer. Updated the calculation in code_comment_extra (with unit test adjustments) so minutes are computed correctly, restoring realistic comment-time estimates and preventing inaccurate reviewer timing metrics.

Add a sparkline to the committer avatar hover (updated in app/javascript/bundles/cab-viewer/cab-committers-frame.js). renderSparkline and tooltip markup were extended to render a 12‑month delta mini-chart inside the hovercard, giving reviewers a compact visual of recent committer activity for faster context.

Update lib/tasks/whenever/pull_requests.rake to queue DiscoverPr jobs more frequently during a repository's early existence since the initial DiscoverPr job now limits scans to main branch plus a buffer. Also sort and reorganize subscription logic (Defines::Subscription and the subscribe_manager Subscription model), adding/adjusting refresh interval behavior. Result: better initial PR coverage for new repos and clearer subscription definitions.

Update RepoReleaseRule to enqueue PR discovery immediately for rules that match pull requests. Added a pull_request_rule? predicate and modified after_create_rule to manually queue discovery when appropriate. This ensures new PR-focused release rules find matching PRs right away instead of waiting for the next scheduled sweep, improving release responsiveness.

Expose an aggregate_by parameter on the Reports API by updating the API definitions and V1::ReportsController to accept and forward aggregate_by for report queries; minor related model and test tweaks included. Clients can now request aggregated reports by a specified dimension, improving reporting flexibility.

Adds a v1 public API endpoint (POST /api/v1/ai_usage) to receive AI usage statistics and includes an integration test (vendor/gems/customer_api/test/integration/api_ai_usage_test.rb). Deployed to production on Oct 22, 2025. Enables clients to submit usage telemetry for improved monitoring, reporting and billing.

Introduce periodic reprocessing for releases and add hooks to periodically refresh defects and issues. Refactored PopulateReleasesFromRule job and added a new releases.rake task in the release_track gem to drive scheduling. Active trials receive higher-frequency refreshes, and cached ResourceTeamStats are only updated for entities with an active subscription. Reduces stale data and avoids unnecessary cache churn.

Extracted default-branch inclusion logic from CommitCompleteJob into a new CommitDefaultBranchConfirmer job (app/jobs/commit_default_branch_confirmer.rb) and added denormalization hooks in CommitSite to invoke it when a commit site has kin on the default branch. This adds a redundant call site to improve reliability of marking commits as present in the main/default branch.

Adds "Test Delta Cohorts" and "Copy/Paste Cohorts" to the AI Cohort stats lineup and refreshes the chart color palette. Fixes palette retrieval in area-chart-segment-colors.js so AreaChart no longer depends on a missing segment prop (derives palette from chartDataPath), preventing incorrect or missing series colors. Result: new cohort options appear and charts render with consistent colors.

Renamed the UI/stat label from "Commit count per AI Cohort" to "Commit Count per Count in AI Cohort" across the stats view and related presenters/helpers (notably app/views/shared/resource_actions/ai_cohorts_stats.html.haml, presenters and defines). These find-and-replace updates standardize phrasing so cohort commit metrics display a clearer, corrected label in the UI.

Consolidates the GitKraken redirect logic from UserUsageProfilesController into a new app/lib/controller_concerns/kraken_controller_concern.rb as KrakenControllerConcern. The moved methods, including notify_gitkraken_and_redirect and confirm_provider_import_with_gitkraken, are now accessible via import or the user usage profile, improving separation of concerns and testability. This modularization enhances reuse and maintainability of the GK redirect behavior.

Rework the redirect decision logic in the repo import flow so that, when there is no evidence that a user has completed the GK redirect, the GK redirect path takes precedence over other redirect types (except the usage/profile path). This change touches app/lib/controller_concerns/repo_import_concern.rb and app/lib/git_kraken.rb, adjusting the priority rules and how completion evidence is evaluated. Benefit: more predictable, correct redirects when GK completion is uncertain, reducing incorre...
