+# Core implementation and migration map
+
+ArtPlayer keeps its existing constructor, player mixins, plugins and DOM/CSS hooks.
+The production entry is still `src/index.js`; this document marks actual migrated
+boundaries rather than describing the entire core as TypeScript.
+
+## Current TypeScript boundary: utilities
+
+| Module | Responsibility and constraints |
+| --- | --- |
+| `src/utils/index.ts` | Existing export barrel; no added runtime names or wrapper methods |
+| `src/utils/format.ts` | Clamp, capitalization, clock formatting and HTML entity conversion; reusable private lookup maps |
+| `src/utils/property.ts` | Native defineProperty alias, own-property inspection and recursive merge; keys are written as own data properties |
+| `src/utils/time.ts` | Sleep, trailing debounce and leading throttle; infer argument tuple/receiver, preserve scheduling and synchronous return behavior |
+| `src/utils/error.ts` | ArtPlayerError, truthiness guard and internal rejection handling; public media promises are handled elsewhere |
+| `src/utils/file.ts` | Historical extension parsing and transient download anchor lifecycle |
+| `src/utils/subtitle.ts` | Existing SRT/ASS-to-VTT text conversions and VTT Blob creation |
+
+These modules do not import the player, UI components or each other except for the
+barrel. Existing DOM and browser capability utilities remain JS and are re-exported
+unchanged. Emitter and Component are separate migration tasks. Imports from the
+barrel must not silently add runtime fields to `Artplayer.utils`.
+
+## Observable utility behavior
+
+- `def` is the native Object.defineProperty function. Property keys include symbols;
+  descriptors, return identity and own-property behavior remain native.
+- mergeDeep iterates own enumerable string keys. Existing nested objects are recursively
+  merged, a previously unseen value retains its reference, and the historical
+  `previous.concat(...incoming)` behavior flattens incoming nested arrays by one level.
+  It returns a new outer object and does not mutate inputs. `__proto__` now becomes
+  an own data key instead of invoking an inherited setter or replacing the result prototype.
+- Debounce discards earlier pending calls and uses the final arguments/receiver.
+  Throttle runs immediately, ignores calls in the wait window and does not schedule
+  a trailing call. Its wait flag is set after invoking the callback: synchronous
+  reentry and retry after a thrown callback retain historical behavior. Both wrappers
+  return undefined. No new public cancel/flush methods were introduced.
+- silencePromise handles only values with a callable catch and preserves other
+  values. It is for internal event handlers; do not wrap public play/toggle promises
+  to hide their rejections. The property-access assertion is local to that duck-typed
+  boundary, and stack capture is guarded for engines that do not implement it.
+- Subtitle conversion preserves the existing limited formats, whitespace and time
+  normalization; it is not a complete ASS parser. The caller owns and must revoke
+  vttToBlob's returned URL. Download owns its temporary anchor and removes it in
+  finally, including click failure. It does not revoke caller-owned URLs.
+
+## Types and remaining work
+
+Migrated sources compile with strict/noUncheckedIndexedAccess and browser-only
+ambient types. The merge accumulator is a dynamic string-key boundary with one
+documented cast to the pre-existing generic return contract. No file-wide any or
+type-check suppression was added. The main public declarations remain a separate
+compatibility surface; see [types/README.md](./types/README.md).
+
+Existing declaration discrepancies are still tracked for CORE-07: Utils lacks some
+runtime exports, def is declared void, debounce/throttle declare the callback return
+instead of void, and debounce's old optional context argument is ignored at runtime.
+Sleep's declaration also requires a delay while runtime defaults to zero. These were
+not silently tightened during source migration; use the actual source types internally.
+Lifecycle-owned timer cancellation is part of CORE-04/17 and the existing BASE-PERF-01
+finding, not a claim that a standalone debounce can know when its owner is destroyed.
+
+## Verification and maintenance
+
+Run `yarn test:unit` for shared published/workspace utility contracts and controlled
+timers. `test/utils.test.js` also accepts `ARTPLAYER_TEST_CORE` to test an actual
+UMD, legacy or ESM file. `test/types/utils-source.ts` checks source inference, receiver
+types and invalid arguments. Test fixtures supply timers explicitly to isolated
+published UMD contexts; production code is not patched for tests.
+
+Run `yarn typecheck`, `yarn build artplayer`, then `yarn build:i18n` (core build clears
+dist first). `yarn test:package:release` rebuilds and installs a candidate outside the
+workspace. Set `ARTPLAYER_BROWSER_ARTIFACTS` to its mapping and run `yarn test:browser`
+for real playback, chapter integration, downloads and Blob URLs. Preserve generated
+core files in docs/compiled when committing a shippable core change.
+
+For new utility behavior, extend the same old/new contract tests. Clearly separate
+intentional defect corrections from preserved behavior. For timers or Blob URLs,
+also identify the owner and verify cleanup in the consuming module. Remaining
+constructor, playback, UI, Emitter, Component and capability migrations are recorded
+in refactor/tasks.json and should extend this map as they land.
