Broque Thomas	c557d9196e	Discover controller — Cin pre-review polish ... Three changes tightening the controller before opening the PR. DROP MAGIC `extractItems` DEFAULTS Controller used to auto-pull `data.items` / `data.albums` / `data.artists` / `data.tracks` / `data.results` when no extractor was supplied. Removed the fallback chain — every section now MUST provide an explicit `extractItems(data) => array`. Validated at register-time so misuse fails immediately, not silently on first load against an endpoint that happened to return two arrays. Cin standard: explicit > implicit. Magic key-grabbing could pick the wrong one in edge cases (e.g. an endpoint returning both `data.albums` and `data.results` would have grabbed albums when the section actually wanted results). All 10 existing controller call sites already passed explicit extractors, so no migration churn — this is purely tightening the contract for future sections. REPLACE `renderItems` NULL-RETURN CONVENTION WITH `manualDom: true` Your Albums and similar sections that delegate to existing renderers that target a CHILD element of `contentEl` used to signal "leave the container alone" by returning null/undefined from `renderItems`. That convention is easy to confuse with an accidental missing-return error. Replaced with an explicit `manualDom: true` config flag. Renderer is still called for its side-effects, controller just skips the innerHTML swap. Clearer intent at the call site. Updated `loadYourAlbums` to use the new flag. PIN THE CONTROLLER CONTRACT WITH JS TESTS Added `tests/static/test_discover_section_controller.mjs` — 32 tests covering the controller's lifecycle contract: - Config validation (every required field, mutual exclusivity of fetchUrl/data, type checks on contentEl) - Happy-path fetch → parse → render - Empty state (default empty render, hideWhenEmpty + sectionEl, success=false treated as empty, custom isSuccess override) - Stale state (fires when isStale returns true, wins over empty, custom renderStale override) - Error state (HTTP non-ok, fetch throws, showErrorToast fires window.showToast, default off doesn't fire) - No-fetch `data:` mode (value + function form, doesn't call fetch) - manualDom mode (skips innerHTML swap, still calls renderer) - Callable `fetchUrl` (resolved at load time, refresh re-resolves) - Load coalescing (concurrent loads share one fetch) - Refresh bypasses coalescing (re-fires fetch every call) - Hook error containment (throwing renderer/onSuccess hooks don't crash the controller) Runs via Node's stable built-in `--test` runner — no package.json, no jest/vitest dependency, no compile step. Just `node --test`. Pytest wrapper at `tests/test_discover_section_controller_js.py` shells out to node and asserts clean exit, so the JS tests fail the regular pytest sweep if the controller contract drifts. Skipped gracefully when node isn't available or is < 22. Closes the "controller is a contract, pin it at the test boundary" gap that Cin would have flagged on review. VERIFICATION - 2205/2205 full pytest suite green (was 2204 + 1 new wrapper) - 32/32 `node --test` pass on the controller test file directly - ruff clean - node --check clean on all touched JS files	3 weeks ago
