Goal

Second Work Metadata E2E rationalization slice: MOVE the oversize-Abstract refuse Chromium scenario to fast layers.

Independent of #207 and of Slice A (#214). Parallel branch on master; rebase after either merges. Does not touch Progress / abstract_excerpt projection E2Es.

What changes

Removes:

OfflineWorkMetadataTests.test_an_oversize_abstract_is_refused_without_touching_anything

Replacement coverage (tip 1248f07):

  • Node selftest installWorkMetadataEditorHarness + real prksSaveWorkMetadataFields('bib') with a spy store — asserts exact refusal status paint, draft retained, saveWorkMetadataFields never called / queue empty
  • Limit helper message + byte-vs-character checks
  • test_the_editor_refuses_an_oversize_value_before_enqueueing — editor abort static
  • Python test_abstract_limit_is_the_same_contract_on_both_paths — server refuse parity

Documents mapping in docs/e2e-performance.md.

Tip-clear (discussion_r4110376219)

Valid: earlier tip’s empty-store assert was vacuous. Fixed by executable DOM/Node editor refusal path (not restored Chromium E2E). No #207 projection coupling.

Count

This slice alone: 57 → 56. Combined with Slice A (#214): 54.

Summary by CodeRabbit

  • Documentation
    • Updated performance notes to reflect that oversized Abstract refusal checks are covered by faster browser and editor tests.
  • Tests
    • Added checks for the editor’s over-limit message and refusal of Abstracts exceeding the 1024 KB UTF-8 limit.
    • Verified that a refused draft is retained and does not trigger a save or queued operation.
    • Removed the slower end-to-end check for oversized Abstract refusal; related validation is covered by the faster checks.

📝 Walkthrough

Walkthrough

The browser selftest checks the exact over-limit Abstract error. It also verifies that ASCII and multibyte drafts over the UTF-8 byte limit remain in the editor without a store save or enqueue. The corresponding end-to-end test was removed. The performance notes record the coverage change and scenario counts.

High-Level Assessment

The test-pyramid approach is appropriate because the oversized-Abstract boundary is a deterministic, non-projection contract already separable into client-message, editor-abort, and server-parity checks. Retaining the browser scenario would preserve integrated UI confidence but duplicate these contracts at substantially higher runtime; projection and conflict E2Es remain intact where browser integration still matters.

P2 Badge Exercise the editor before asserting the queue stays empty

The refuseStore is freshly created and no editor or store-save path is invoked, so listOperations() is guaranteed to be empty even if the editor later starts enqueueing oversized Abstracts. The cited Python test only scans the editor source for prksWorkFieldLimitError and an arbitrary return;, while the other assertions exercise only the limit helper; consequently, removing the E2E scenario drops executable coverage of the actual refusal flow, including the status message, retained draft, absence of a request, and unchanged server state. Retain that scenario or replace this with an executable editor-level test that submits the oversized draft and observes those effects.

Found one remaining coverage gap in the MOVE replacement.

const refuseStore = createPrksLocalStore({ indexedDB: createFakeIndexedDBFactory(), uuid });
assert.equal(globalThis.prksWorkFieldLimitError('abstract', 'x'.repeat(limit + 1)) == null, false);
assert.deepEqual(await refuseStore.listOperations(), [],

P2 — The replacement does not execute the editor refusal path it is supposed to replace. This creates a fresh store, calls prksWorkFieldLimitError() directly, and then asserts the untouched store is empty. That assertion is vacuous: no editor save handler or store write was attempted. The removed E2E proved the real UI path kept the oversize draft on screen, rendered the refusal, made no durable operation/network mutation, and left the server unchanged. The current static Python check only proves the editor source text contains prksWorkFieldLimitError and a return before saveWorkMetadataFields; it can still pass if the wrong branch returns or the status/draft behavior regresses. Either retain a thin browser E2E for the actual save refusal, or add an executable DOM/Node editor test that invokes the real save handler with a spy store and proves: refusal status rendered, saveWorkMetadataFields/network not called, and the draft remains intact.

Later pass (1248f07 → rebase tip 4156aea): one new issue after landing on Slice A.

Earlier finding

The vacuous empty-store assert (discussion on b9fc051) is fixed — tip exercises prksSaveWorkMetadataFields via the harness and asserts refusal paint, retained draft, and no saveWorkMetadataFields / empty queue.

New

  1. Blocking — duplicate editor harness after rebase onto Slice A. Master already ships makeMetaEl / installWorkMetadataEditorHarness (Slice A editorCoalescing). Tip re-adds a byte-identical second copy before abstracts(). SonarCloud quality gate fails: 82% duplication on new code (required ≤ 3%). Delete the second copy and call the existing harness from the oversize-Abstract refuse block.

CI: lint/static/Unit+API green; CodeQL green; Full E2E still running; SonarCloud failed on duplication.

/* Minimal DOM + focused-tab harness for the REAL work-metadata-editor save
* path. Store-only coalescing / limit helpers do not exercise dirty detection,
* status paint, draft retention, or the abort-before-enqueue ordering. */

Blocking — duplicate harness after rebase onto Slice A.

makeMetaEl / installWorkMetadataEditorHarness already exist at lines 93 / 165 (Slice A, used by editorCoalescing). This tip re-adds a byte-identical second copy. SonarCloud is failing the PR quality gate on 82% new-code duplication (≤ 3% required) for exactly this reason.

Delete this second definition (through the matching installWorkMetadataEditorHarness below) and keep the oversize-Abstract refuse block calling the single top-of-file harness.

Fixed: deleted the second byte-identical makeMetaEl / installWorkMetadataEditorHarness copy. Oversize-Abstract refuse now uses the single top-of-file harness from Slice A. Node selftest: 517 checks passed. Pushing tip — new CI/Full E2E will replace 36256699243.

After rebase onto Slice A, makeMetaEl / installWorkMetadataEditorHarness
were re-added byte-identical. Keep the single top-of-file harness; oversize
Abstract refuse still calls it. Clears Sonar duplication gate failure.

tests/browser/run_work_metadata_sync_selftest.js:1831-1853
🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Exercise the UTF-8 byte-limit case through saveBib().

The editor test uses ASCII input, which exceeds both the character and byte limits. An editor regression that checks abstract.length instead of UTF-8 bytes would still pass this test. The existing multibyte assertions cover the helper, but not the editor save path.

Add a multibyte Abstract with .length < limit and UTF-8 bytes > limit.

Suggested fix
         assert.equal(harness.inputs.abstract.value, oversize, 'the draft stays on screen');
         assert.equal(harness.inputs.abstract.value.length, limit + 1);
+        const multibyte = '\u65e5'.repeat(Math.floor(limit / 3) + 10);
+        assert.ok(multibyte.length < limit);
+        assert.ok(prksWorkFieldUtf8Bytes(multibyte) > limit);
+        harness.inputs.abstract.value = multibyte;

+        assert.equal(harness.saveCalls(), 0,

ASCII oversize alone would still pass if the editor checked .length instead
of prksWorkFieldLimitError. Exercise chars < limit / UTF-8 bytes > limit on
the real save path (Slice B contract).

CodeRabbit Trivial (UTF-8 saveBib) — KEEP.

Editor save uses prksWorkFieldLimitError (UTF-8 bytes), and helpers already cover multibyte arithmetic. ASCII oversize through saveBib() still would not catch an editor regression to .length. Prefer false-positive coverage for Slice B’s refuse contract.

Waited for Full E2E 36257055949 green on 43c2b96, then tip-cleared with a minimal multibyte saveBib() case (chars < limit, UTF-8 bytes > limit). Node: 523 checks PASS. Tip 84d7935 — new Full E2E required (executable test change).
