- Split client, native, remote, serve, markdown, and SDK internals into focused packages with direct imports.
- Move local and remote transport framing/protocol helpers behind clearer module boundaries.
- Break up the extension injected DOM logic into a separate content dispatch bundle and dedicated content modules.
- Add explicit client handling for passive remote discovery without noisy PQ warnings.
- Keep behavior covered with updated unit, integration, and extension tests.
Restructure the MV3 background worker from a monolithic core.ts/index.ts
into a class-based command architecture. Behavior is identical — the 83
registered commands dispatch byte-for-byte the same as before.
Structure
- One class per command group, each extending CommandGroup and exporting a
`commands` map keyed by the full command id ("tabs.close"). Groups:
Navigation, TabsMutation, TabsQuery, Groups, Windows, Dom (dom/extract/
page), BrowserData (storage/cookies), Session (session/clients + autosave
+ lazy-tab activation), Perf (perf + jobs.status/cancel), Extension.
- CommandRegistry merges the group maps (throws on duplicate ids), routes
background specs to JobManager and paginates array results via
makePagedData. JobManager owns the job map + lifecycle. NativeConnection
owns the native-port lifecycle and the inbound message router.
- index.ts is now thin wiring: JobManager -> ctx -> assembleRegistry ->
onActivated -> NativeConnection.start().
- Infra classes live in classes/ (PascalCase, file = class name); command
groups in commands/; shared helpers split out of core.ts into core/
(errors, throttle, scripting, tab-helpers, group-helpers, storage); all
types moved into types/ (json, jobs, session, tabs, messages,
command-args) behind a barrel.
DRY cleanup
- resolveTabUrl(tabId) and assertScriptableUrl(url, action) collapse the
tab/URL-guard boilerplate duplicated across dom.ts and browser-data.ts.
- processInBatches() centralizes the throttled, cancellable batch loop
shared by tabs.close, group.close and tabs.merge_windows.
- captureCurrentSession() dedups the snapshot-and-signature block shared by
session.save and the autosave path.
- DomArgs type alias replaces 21 inline ContentArgs & { tabId? } copies.
- Drop fetchTabHtml's redundant retry loop (executeScript already retries
transient frame/tab errors), a dead tabInfo import, and two stale
comments referencing a removed asArgs helper.
Type safety & tests
- Full noImplicitAny; no `any`/`unknown` annotations remain in src.
- JS unit-test harness using node --test + node:assert (zero new deps),
bundled via the existing esbuild. Covers JobManager retention/lifecycle
and the autosave listener-wiring/debounce with an in-memory chrome mock.
- The structural pytest checks track the new file homes and the centralized
processInBatches helper.
Verification: npm run check:extension green (tsc + esbuild 84.5kb +
node --check + 18 JS tests); uv run pytest -q -> 409 passed, 105 skipped.
No version bump.
