Introduce scanning for the presence of "safety words" and persist DuplicateContentBlock data into CodeLine to support research data generation. Adjust language line parsers (Scala, VB) and update CodeLine to accept duplicate-block references. Deployed to production on May 13, 2026 — enables collection of duplicate-content signals for analysis.

Update PagesController to add npm-installer support and inject per-entity GitClear API bearer tokens into Claude telemetry JS. Stable telemetry JS skips same-origin for installer requests and is served inline; non-installer requests require authentication and redirect to entity-specific telemetry pages. Controller resolves entity (params or preferred), fetches CustomerApiToken.gitclear_token, builds first-time and set-token install commands, and embeds the token into telemetry downloads—enabl...

Implement post-token v1 AI API validation: add a LlmTokenValidation job and validation helpers in llm_metrics (LlmApiToken) to build connection validation payloads, detect timed-out validations, and fail timed-out checks via fail_timed_out_connection_validation!. Released to production May 8; improves detection and handling of invalid or unreachable AI API tokens.

Add 'defect rate' as a tracked metric per LLM. Updated llm_metrics calculation and model (vendor/gems/llm_metrics/app/models/concerns/llm_resource_stat_creation_calculation_concern.rb and vendor/gems/llm_metrics/app/models/llm_resource_stat.rb) and adjusted segment definitions. Context: #pub Add "defect rate" to stats tracked per LLM. Impact: enables per-LLM defect-rate monitoring and dashboarding.

Add a new resource stylesheet (app/assets/stylesheets/resource/ai/_ai_roi_stats.scss), refine compare-stat.scss and tweak the AI ROI stats view (app/views/shared/resource_actions/ai_roi_stats.html.haml); a minor reorder in report_tabs.rb. These markup and CSS refinements polish the AI ROI comparison display for clearer, more consistent presentation in reports.

Replaces the legacy imperative commit value editor with a new JS component (moved code into app/javascript/apps/commit-diff-delta-editor.js and updated app/assets/javascripts/commits/_show.js), enabling explicit percentage attribution of human vs LLM work. Cleans up assorted prop warnings and removes legacy code paths; deployed to production on Apr 12. Impact: clearer attribution UI and reduced console noise.

Remove the CommitValue states pending_review and rejected and replace them with logic that flags commits with exceptional velocity as LLM-authored CI runs. Updated commit value evaluation (CommitConcerns::ValueEvaluationConcerns) and tests to use deduced AI assignment state. Result: simpler commit state model and improved detection of AI/LLM-generated CI runs.

Update app/models/commit_value.rb to remove pending_review and rejected states and introduce pending_ai_assignment and llm_complete. Rename and add callbacks (detect_zero_pending_ai_assignment, sync_pending_ai_assignment_values, handle_pending_ai_assignment_complete), expand included_in_stats, and adjust approved_value, impacting? and derive_number_authority_em to treat exceptional-velocity commits as LLM/CI-authored. Result: LLM-generated CI runs are identified and correctly included in stat...

Surface the Replace Markdown action directly in the selection menu (app/javascript/lib/ample-editor/components/selection-menu.js): moved and consolidated the ConvertFromMarkdownButton logic and adjusted related ExtractContentButton code so replacing markdown no longer requires a second click when applicable. Deployed to production 2026-03-31 — reduces user clicks and streamlines editor workflow.

Add a callback on UserUsageProfile that enqueues SuggestStarredReportsJob when a user provides a mission. The job emails the user actionable, clickable report suggestions they can add to their dashboard (app/jobs/suggest_starred_reports_job.rb). Improves report discoverability and speeds dashboard setup for users.

Introduce app/javascript/apps/starred-report-picker.js implementing a Starred Report Picker UI: filterSuggestions (autoExpandTextarea, buildSuggestionList, description handlers, keydown), saveStarredReport flows (renderAutosuggestItem, handleSearchInputChange, requestAiSuggestions, renderAiSuggestionCard). Adds autosuggest, keyboard handling and AI-driven suggestion cards to improve report discovery and save UX.

Updated app/lib/stats/dora_history.rb to compute change_failure_rate instead of release_defect_percent. Built out all_time_defect_finder alongside period_defect_finder, refined previous/period release finders, and reused the concerns_team scope for a second use — updating it to accept a resource so team+resource can derive repo_ids. Result: reusable scopes and correct change-failure-rate metrics for DORA reporting.

Add a new V1 ApiTokensController endpoint (customer_api gem) to provision a user using a personal access token (PAT). Implements provision_user flow plus helpers to attach provisioned avatars, ensure provisioned entities and remote connections, and fetch provisioned organization counts. Includes tests. Enables programmatic user provisioning for integrations and automated onboarding.

Prefer PR-based release assignment when backfilling commit->repo_release links. Added assign_pull_request_commits logic in backfill_commit_release.rb and adjusted ensure_repo_release_recorded/related checks in commit_repo_issue_concerns so a commit will use its PR's repo_release when available. Result: more accurate release attribution for commits during backfill.

Render LLM-generated deltas in the directory browser alongside the existing standard per-directory delta. Updated renderColumnDelta in app/javascript/bundles/directory-browser/browser-column-renders.js and adjusted corresponding SCSS layout rules (repo-file-browser.scss); minor related touches in all-files-browse-frame.js. Benefit: surfaces model-suggested changes in the UI so users can see LLM deltas next to regular diffs.

Add new stat segments commit_ai_lines_committed_count and delta_from_llms. Updates include StatSegments definitions, LlmResourceStat model additions, updates to the LLM resource stat creation/calculation concern, and chart icon mappings in ApplicationResourceHelper. Enables collection, calculation and UI display of AI commit line counts and LLM delta metrics for dashboards and alerts.

Added a new documentation page (app/views/pages/mathematics_of_diff_delta.html.haml) for Claude v1 detailing the "Mathematics of Diff Delta". Deployed to production on 2026-03-04. Provides a formal explanation of the diff-delta math to help engineers and users understand model behavior, improve debugging, and aid onboarding.

Implement _onKeyDown and wire it into the EditingCommentContent render (app/javascript/bundles/commit-comment-reaction/components/editing-comment-content.js) so pressing Escape cancels/dismisses the comment input area while preserving existing key behavior. Improves UX by enabling quick keyboard dismissal of the comment editor.

Corrected parameter parsing in CustomerApiBaseController#derive_api_request_committer so a provided committer_identifier that is a remote_id is correctly recognized; updated integration tests (vendor/gems/customer_api/test/integration/api_ai_usage_test.rb). This fixes AI API usage stats attribution and restores accurate committer identification.

Implement logic in CommitConcerns::ValueEvaluationConcerns (app/lib/commit_concerns/value_evaluation_concerns.rb) to deduce value/state for LLM-authored, high-velocity commits and auto-approve them as valid Diff Delta. Added tests in vendor/gems/llm_metrics/test/jobs/assign_commit_llm_model_test.rb. Impact: such commits are auto-marked valid and rewards are split between the developer and the LLM.
