- Added `ROBOMP_ISSUE_INDEX_SYNC_SECONDS` configuration and lifecycle-managed issue indexing through startup/shutdown hooks.
- Added issue/PR index tables with FTS5 triggers plus upsert and keyword/filter search helpers for indexed records.
- Added GitHub backend/proxy support for `IssueIndexEntry` and issue-index page retrieval, including webhook ingestion and periodic watermark-driven sync.
- Updated `gh_search_issues` to prefer local index queries when synchronized and added `search_commits` host tool with query modes and validation.
- Added `wontfix` to primary classification handling by updating host-tool classification metadata and issue taxonomy prompts.
- Updated kickoff/follow-up/system prompt guidance to treat intentional-design reports as `wontfix`, with maintainer-intent signals stopping work and ending in a single explanatory comment.
- Added tests to verify `classify_issue` persists a `wontfix` classification and returns a no-PR, comment-only next step.
- Introduced `Max` as a first-class reasoning effort tier across all packages, including AI providers, coding agent configurations, and RPC protocols.
- Refactored model effort ladders to use wire-exact mappings and removed legacy effort aliasing (e.g., `max-to-xhigh` mapping).
- Updated model registry and provider configurations to support `Max` tier routing, color themes, and UI icon associations.
- Expanded test suites to provide end-to-end coverage for the new reasoning tier, including updated compatibility and fallback scenarios.
- Implement `has_authorized_impl_event` in the database to retrieve historical authorization state.
- Update `_enforce_impl_authorization` to permit actions if prior events on the issue provided implementation authorization.
- Normalize maintainer logins by stripping `[bot]` suffixes and allow match-regex to ignore them.
- Implemented case-insensitive normalization for bot logins to handle mention handles and `[bot]` suffixes consistently.
- Added support for `ROBOMP_MAINTAINER_LOGINS` to allow authorized non-owner users to execute implementations.
- Refined authorization logic to distinguish between personal repository owners and organizational accounts.
- Updated documentation and added comprehensive tests to verify authorization handling across tasks, workers, and directive processing.
- Updated configuration to strip the '@' prefix from bot login names.
- Granted personal repository owners authorization to trigger implementations regardless of their GitHub author association.
- Introduced a vouching mechanism to manage PR authorization via a tracked user list and discussion-based management workflows.
- Added automated PR gatekeeping workflows to close contributions from unvouched users and require specific labels for review.
- Refactored PR event handling to support label-based review deferral and enforce authorization checks for labelers.
- Added comprehensive test coverage for vouch-gate logic, including label activation and unauthorized access scenarios.
- Added event retry settings with parsed delay schedules and jittered delay computation.
- Extended event persistence to persist an `available_at` timestamp, honor it during dequeuing, and clear it when re-queuing.
- Updated worker failure handling to queue bounded retries with backoff and transition to failed only when the retry budget is exhausted.
- Added `review_pr` task that checks out PR head in a detached worktree, classifies rank/type/area, and posts a batched GitHub review as `event=COMMENT`.
- Added four new host tools: `fetch_pr`, `classify_pr`, `pr_review_comment`, and `submit_pr_review`; review tools self-gate on `review_mode`, push/open-PR tools refuse when `review_mode` is set.
- Added sqlite staging table `pr_review_comments` with `stage_review_comment`, `list_staged_review_comments`, and `clear_staged_review_comments` DAOs.
- Routed `pull_request.opened/reopened/ready_for_review` to `review_pr` and extended `pull_request.closed` cleanup to any tracked PR regardless of author.
