+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+The core/services directory has inconsistent naming patterns that create confusion:
+- Some files use `*Service.ts` suffix (e.g., `mpv-service.ts`, `tokenizer-service.ts`)
+- Others use `*RuntimeService.ts` or just descriptive names (e.g., `overlay-visibility-service.ts` exports functions with 'Service' in name)
+- Some functions in files have 'Service' suffix, others don't
+
+This inconsistency makes it hard to predict file/function names and creates cognitive overhead.
+
+Standardize on:
+- File names: `kebab-case.ts` without 'service' suffix (e.g., `mpv.ts`, `tokenizer.ts`)
+- Function names: descriptive verbs without 'Service' suffix (e.g., `createMpvClient()`, `tokenizeSubtitle()`)
+- Barrel exports: clean, predictable names
+
+Files needing audit (47 services):
+- All files in src/core/services/ need review
+
+Note: This is a large-scale refactor that should be done carefully to avoid breaking changes.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Establish naming convention rules (document in code or docs)
+- [x] #2 Audit all service files for naming inconsistencies
+- [x] #3 Rename files to follow convention (kebab-case, no 'service' suffix)
+- [x] #4 Rename exported functions to remove 'Service' suffix where present
+- [x] #5 Update all imports across the entire codebase
+- [x] #6 Update barrel exports
+- [x] #7 Run full test suite
+- [x] #8 Update any documentation referencing old names

+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Starting implementation. Planning and executing a mechanical refactor: file names and exported symbols with Service suffix in `src/core/services`, then cascading import updates across `src/`.
+
+Implemented naming convention refactor across `src/core/services`: removed `-service` from service file names, renamed Service-suffixed exported symbols to non-Service names, and updated barrel exports in `src/core/services/index.ts`.
+
+Updated call sites across `src/main/**`, `src/core/services/**` tests, `scripts/**`, `package.json` test paths, and docs references (`docs/development.md`, `docs/architecture.md`, `docs/structure-roadmap.md`).
+
+Validation completed: `pnpm run build` and `pnpm run test:fast` both pass after refactor.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Normalized `src/core/services` naming by removing `-service` from module filenames, dropping `Service` suffixes from exported service functions, and updating `src/core/services/index.ts` barrel exports to the new names. Updated all import/call sites across `src/main/**`, service tests, scripts, and docs/package test paths to match the new module and symbol names. Verified no behavior regressions with `pnpm run build` and `pnpm run test:fast` (all passing).

 - To add or change a config option, update `src/config/definitions.ts` first. Defaults, runtime-option metadata, and generated `config.example.jsonc` are derived from this centralized source.
-- Overlay window/visibility state is owned by `src/core/services/overlay-manager-service.ts`.

 - MPV service has been split into transport, protocol, state, and properties layers in `src/core/services/`.
 - Prefer direct inline deps objects in `src/main/` modules for simple pass-through wiring.
