     - `ai-pull-request-description-mode`: Select the PR body policy: `replace` owns the complete generated body, `append` preserves human text and maintains a Copilot-managed section, `preserve` never updates automatically but allows `/copilot description`, and `disabled` never changes the body. Defaults to `replace`.
-    - `issues-locale`: Target locale for explicitly addressed issue comments (default: "en-US"). When an addressed comment is in another language, the configured agent translates it to this locale. See [Agent CLI configuration](/agents/cli-configuration).
-    - `pull-requests-locale`: Target locale for explicitly addressed PR review comments (default: "en-US"). Same translation behavior as `issues-locale` but for PR comments.
+    - `repository-locale`: BCP-47 target locale for repository-facing product messages (default: `en-US`). Values are validated and canonicalized (`pt_BR` is accepted during migration and becomes `pt-BR`).
+    - `issues-locale`: Optional issue-surface override. Its empty default inherits `repository-locale`; an explicit existing value remains authoritative.
+    - `pull-requests-locale`: Optional pull-request-surface override. Its empty default inherits `repository-locale`; an explicit existing value remains authoritative.
+
+    Addressed comments are interpreted in the effective surface locale with at most one agent call. Copilot never edits the human-authored source comment. When translation is needed, the useful bot response includes a collapsed, escaped copy of the interpreted request and original text. Unaddressed comments remain inert. Commands, paths, refs, URLs, identifiers, machine-readable fields, and operational logs are not localized. See [Agent CLI configuration](/agents/cli-configuration).
     - `ai-ignore-files`: Comma-separated list of paths to ignore for AI operations (e.g. progress detection, Bugbot; not used for PR description, where the agent computes the diff in the workspace).
     - `bugbot-severity`: Minimum severity for Bugbot findings to report: `info`, `low`, `medium`, or `high` (default: `low`). Findings below this threshold are not posted on the issue or PR.
     - `bugbot-comment-limit`: Maximum number of findings to publish as individual issue comments or inline PR review comments (default: `20`). Extra findings are summarized in the PR review body or in one issue-only overflow comment. Clamped between 1 and 200.
