TASK-309	Accept modified follow-up digits for multi-line sentence mining	Done	@codex	2026-04-27 20:06	2026-04-27 20:15	bug linux shortcuts		high

Description

On Linux, Ctrl+Shift+S starts multi-line sentence-card mining, but the follow-up digit is not accepted and the prompt times out. Restore reliable digit capture for the multi-mine flow, including the common case where the original shortcut modifiers are still held briefly while pressing the digit.

Acceptance Criteria

• #1 Ctrl+Shift+S followed by a number-row digit creates a counted mineSentenceMultiple request instead of timing out.
• #2 Follow-up digit capture works when the user has not fully released Ctrl/Shift after the starter shortcut.
• #3 Regression coverage includes renderer session bindings and mpv plugin numeric selection.

Implementation Notes

Backlog MCP unavailable in this session, so this task is tracked via repo-local backlog files.

Implemented renderer digit extraction from KeyboardEvent.code for pending numeric selection, so shifted number-row events such as Ctrl+Shift+Digit3 still dispatch count 3. Updated the mpv plugin session-binding numeric selector to register bare digits plus the starter shortcut modifier combinations, so plugin-owned Ctrl+Shift+S can accept a follow-up digit before the modifiers are fully released.

Verification:

• bun test src/renderer/handlers/keyboard.test.ts src/core/services/overlay-shortcut-handler.test.ts src/core/services/overlay-window.test.ts
• bun run test:plugin:src
• bun run changelog:lint
• bun x prettier --check src/renderer/handlers/keyboard.ts src/renderer/handlers/keyboard.test.ts package.json 'changes/309-multi-mine-modified-digits.md' 'backlog/tasks/task-309 - Accept-modified-follow-up-digits-for-multi-line-sentence-mining.md'

Final Summary

Restored multi-line sentence-card digit capture for the case where Ctrl/Shift are still held after Ctrl+Shift+S. The renderer now accepts digits by physical Digit1-Digit9/Numpad1-Numpad9 code during pending numeric selection, and the mpv plugin registers the matching modified digit bindings for session-binding numeric prompts.
