- Added `search_issues` support to the GitHub backend and client, including `state_reason` and `is_pull_request` in issue summaries.
- Added the `gh_search_issues` host tool with repo-prefixed query handling, non-empty/restricted `repo:` validation, default and bounded `limit` values, and inbound issue filtering.
- Added proxy integration for issue search with a new `/gh/v1/search_issues` endpoint and matching proxy-client method/response parsing.
- Updated triage prompts to perform pre-`classify_issue` duplicate and already-fixed checks via search, and added tests for search query formatting, validation, and state-aware match rendering.
- Updated the system prompt to require additional bug-gate checks, including repo-owned-defect and premise-verification before labeling a report as `bug`.
- Added non-bug routing guidance for upstream-caused failures, environment/user errors, duplicate audit batches, and out-of-scope or already-possible scenarios.
- Adjusted host-tool and issue kick-off prompt instructions to call out upstream vs this-repo cause checks and expanded wontfix rationale wording.
- 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.
- Removed `selector`/`sel` arguments from read and grep tool schemas and related execution arg handling.
- Reworked read and grep path processing to parse line selectors from `path` suffixes instead of separate fields, including inline range propagation.
- Updated delegation and execution call paths (including JS/Python preludes and executor tests) to pass selectors embedded in `path`.
- Updated read/grep prompt docs and changelog for the breaking inline-selector API, and removed obsolete selector-specific tests and expectations.
- plugin-install-validation mocks now answer the bun pm cache probe that refreshBunGitCache issues before bun update on git re-installs.
- working-accent tests render the loader before asserting accent computation counts: colorizers run lazily at render time since the loader layout cache landed.
- Replaced the advisor turn validation to raise errors only when a turn has no assistant response at all, instead of treating a content-less `stop` as a failure.
- Kept zero-content silent reviews from entering the retry/rollback/warn path by no longer raising "Advisor unavailable" for completed empty-stop turns.
- Updated advisor runtime tests and changelog language to assert and document that consecutive zero-usage silent turns now succeed without notifications.
