Goal

First Work Metadata E2E rationalization slice: move durable-queue core Chromium coverage to fast layers, following the Work-Tag pilot (#204) KEEP / SPLIT / MOVE policy.

Independent of #207 (Work read projections). No projection E2Es (cards/search/recent/grouping overlays) are touched.

What changes

SPLIT — coalescing (store + editor Save)

Removes:

OfflineWorkMetadataTests.test_repeated_edits_coalesce_and_returning_to_base_cancels

Replacement:

  • coalescing() — store A→B→C / repeat-noop / edit-back-to-base
  • editorCoalescing() — real prksSaveWorkMetadataFields bib Save via DOM harness: never-sent pending DOI stays editable; second Save dirties against pending; edit-back-to-base cancels

SPLIT → fast layers — lost response

Removes:

OfflineWorkMetadataTests.test_lost_response_applies_the_edit_once

Adds:

  • Node lostResponse() — transport loss leaves original envelope pending; retry preserves exact op_id + semantic envelope; acknowledged replay retires
  • Python test_idempotency_normalization_and_reuse — exact ledger replay + OP_ID_REUSE
  • HTTP test_work_metadata_sync_http_lost_response_replay — /api/sync/operations commit, drop response, identical-envelope replay; DOI revision stays 1 (CodeRabbit outside-diff)

Documents the mapping in docs/e2e-performance.md.

Tip-clear

  • Codex P2: store-only coalescing() was insufficient — added editorCoalescing() editor Save path coverage.
  • CodeRabbit outside-diff: mock transport + direct process_operation missed the HTTP adapter — added endpoint-level lost-response replay.

Count

tests/e2e/test_work_metadata_offline.py: 57 → 55 Chromium scenarios.

Non-goals / deferred

  • Projection-coupled families (publisher/year/status/title/author/thumb/abstract Progress) — wait for arch: #60 Slice C — centralize Work read projections #207
  • Conflict UI buttons, offline reload+reconnect, diagnostics, hydration, online wiring — KEEP for later slices
  • Work Source / Tags / harness streams — other owners

Validation

  • tests.test_work_metadata_sync + tests.test_frontend_work_metadata_sync (includes Node selftest) green.
  • tests.test_server_api.TestServerAPI.test_work_metadata_sync_http_lost_response_replay green.

Summary by CodeRabbit

  • Reliability
    • Added validation that retrying an operation after a lost response does not apply the change twice.
    • Added checks that identical retries preserve the saved revision, while reusing an operation identity with different content leaves saved data unchanged.
  • Testing
    • Added focused checks for repeated edits, including combining pending changes and clearing them when a value returns to its acknowledged state.
    • The browser end-to-end suite now includes 55 Chromium scenarios, with offline editing and retry behavior covered by focused tests.

📝 Walkthrough

Walkthrough

The change updates Work metadata sync test coverage. It adds browser self-tests for edit coalescing and lost-response retries, adds server tests for operation idempotency, removes two offline E2E scenarios, and updates the documented Chromium scenario count.

Changes

Work metadata sync coverage

Layer / File(s) Summary
Browser durable-queue coverage
tests/browser/run_work_metadata_sync_selftest.js, tests/e2e/test_work_metadata_offline.py, docs/e2e-performance.md
The browser self-tests cover edit coalescing, edit-back cancellation, and lost-response retry with the same operation ID and envelope. The offline E2E tests no longer cover repeated-edit coalescing or lost-response retry. The documentation records the coverage split and updates the Chromium scenario count from 57 to 55.
Server idempotency coverage
tests/test_work_metadata_sync.py, tests/test_server_api.py
Tests verify that an identical operation replay returns its original result. They also verify that reusing the operation ID with a different payload returns OP_ID_REUSE without changing the stored DOI or revision, and that an HTTP-level replay is acknowledged at revision 1.

Rationalize Work Metadata Core Protocol E2E Coverage

Grey Divider

AI Description

• Moves redundant Work metadata coalescing coverage from Chromium to the Node selftest.
• Splits lost-response guarantees across client retry and server idempotency tests.
• Documents retained browser scope and reduces Chromium scenarios from 57 to 55.

High-Level Assessment

The split-layer approach is appropriate because neither removed scenario depends on uniquely browser-visible behavior. Keeping both Chromium tests would duplicate coverage and retain avoidable runtime, while a single replacement integration test would be slower without isolating client retry and server ledger responsibilities as clearly.

Cover lost-response envelope replay in Node

• Adds a lost-response selftest proving the original operation remains pending, retries with an identical operation ID and semantic envelope, and retires after acknowledgement. Registers the scenario in the selftest runner.

Remove redundant core protocol Chromium scenarios

• Removes browser scenarios for repeated-edit coalescing and lost-response idempotency. Their protocol guarantees are now owned by existing and newly added fast-layer tests, reducing this module from 57 to 55 scenarios.

• Adds a protocol test confirming exact envelope replay returns the ledgered result without incrementing revision. It also verifies that reusing the operation ID with a different payload returns 'OP_ID_REUSE' without mutating state.

P2 Badge Keep UI coverage for repeated metadata edits

The cited coalescing() replacement calls saveWorkMetadataFields() directly and never loads work-metadata-editor.js, so it does not replace the deleted browser scenario’s verification that a never-sent pending field remains editable and that subsequent Save clicks diff against the displayed pending value. For example, changing busy() to disable every pending field, or wiring the editor to diff against the server value, would break the user’s second edit and edit-back-to-base cancellation while this selftest and the remaining single-save E2Es still pass. Retain a UI-level test for this interaction or add a fast DOM/editor integration test rather than classifying the direct store test as full replacement coverage.

🗄️ Data Integrity & Integration | 🔵 Trivial | 🏗️ Heavy lift

Retain endpoint-level lost-response replay coverage.

The new lostResponse test uses a mock transport, and the backend test calls sync_protocol.process_operation directly. Retained E2E tests cover normal endpoint delivery only. A regression in /api/sync/operations after a committed request loses its response can therefore pass all replacement tests.

Add an HTTP-level integration test outside Chromium. Make the first response unavailable after the endpoint commits the operation, replay the same envelope, and assert that the server revision remains 1. This preserves the move away from Chromium without losing endpoint-boundary coverage.
