## Thinking Path > - Paperclip helps people manage AI agents and their work. > - The Mine inbox combines task rows with approval and failure items. > - It waits for parent captions before it reveals the initial list. > - It fetched rich diagnostics for every parent, including parents already in the task index. > - Parent captions only use fields that the index already provides. > - This change reuses loaded parents and fetches missing parent metadata through the index view. > - Failure items keep their rich interruption data and the initial reveal boundary stays in place. ## Linked Issues or Issue Description **What existing behavior does this improve?** The initial load of Mine and other inbox views that need parent task captions. **Subsystem affected** `ui/` collection reads. The API contract and database schema stay the same. **Current behavior** The inbox fetches all parent and failed-run task IDs with `view=rows` after the primary task request. This adds active-run, blocker, review, interruption and recovery work to the reveal path. The observed hosted case fetched four parents. One was already in the 31-row task index. The other three were completed parents. The serial context response took 1.0–2.9 seconds during the diagnostic reloads. **Proposed behavior** Reuse parents from the selected source index. Fetch missing parents with `view=index`. Keep `view=rows` for every failed-run task, including overlaps with parents or source rows. Keep both role-specific ID lists in the query key. Drop old placeholder rows when the new index supplies a parent. **Reason and benefit** This removes unnecessary diagnostic work from a required serial request. Five alternating same-four-parent requests on the hosted app had index times of 189, 162, 156, 128 and 169 ms, versus rich-row times of 282, 211, 329, 219 and 284 ms. All requests missed the response cache. All consumed parent fields matched. This isolates the projection cost; it is not a deployed UI speedup claim. **Breaking changes** None. Membership, ordering, nesting, archive state, authorization and failure presentation retain their owners and contracts. Refs: #18323 and #18492 for the prior collection and startup work. This change addresses the remaining parent-context read. ## What Changed - Partition missing parent metadata from failed-run context. Load the two batches concurrently, with at most two batch requests in flight. - Keep richer failure rows last in the context result. Filter placeholders by company and current requested IDs. Track completed failure reads, including missing tasks, so a parent placeholder cannot reveal an unverified failure card. Keep existing verified cards mounted through refresh. - Cover delayed captions, reuse of indexed parents, refreshed parent captions, failure overlaps, resolved failures and parent-to-failure cache transitions. - Add a real browser check for delayed parent metadata and stable geometry through deferred diagnostics. Give the test its own disposable company. - Add a reusable local timing harness and update the collection verification recipe. ## Verification - Baseline source: `0710c5684243a663c09ff907011ab88838173a02`. Final measured candidate: `c8c69b5af11966b4144707a3da21e840c73c6cca`. Production UI assets were built from the same checkout and dependencies, with only the Inbox module changed between variants. - Targeted regression failed on the old implementation and passed after the change. All 58 Inbox component tests pass, including existing archive/undo and order checks. - Full workspace typecheck passes. The final UI typecheck passes. Full build passes. Token gates, map checks and diff whitespace checks pass. - All 12 collection browser checks pass, including pagination and reading-position restoration. - The full CI workflow passes on `c8c69b5af11966b4144707a3da21e840c73c6cca`, including all server, chat, workspace, serialized, runner and E2E shards. [CI run](https://github.com/paperclipai/paperclip/actions/runs/41502803275). Greptile reports 5/5 on this commit with no unresolved threads. The separate Paperclip Review check is still queued. Its first attempt saved a text result but did not complete the GitHub assessment. Normal retry was rejected because that attempt already recorded a result. The current-head review request is queued. The review service is now unavailable, so this external gate remains open. - The duplicate local `pnpm test:run` was interrupted after the equivalent CI run passed. Its six chat shards passed 1,828 tests. The general-server phase was stopped. This local full-suite run is incomplete, not a passing result. - Local synthetic fixture: four parents and 30 children, with three completed parents archived. The fixture also has 30 archived child records. No agent or provider calls ran. Mac arm64, Node 24.22.2, Chromium, production assets, 1440×900, native CPU, loopback network, fresh HTTP/query caches for each cold sample. - Five alternating local pairs produced identical 31-row membership and order and no browser errors: | Journey | Baseline median (range), ms | Candidate median (range), ms | Median paired saving, ms | | --- | --- | --- | --- | | Cold first usable Mine rows | 310 (252–435) | 258 (250–261) | 50 | | Warm Recent → Mine | 60 (56–64) | 67 (61–71) | -7 | | Task → Back to Mine | 42 (40–47) | 43 (40–45) | 0 | The final cold result has a material control limitation. The median primary-request start was 259 ms for baseline and 210 ms for candidate. Much of the cold difference occurs before the changed request. The parent response medians were 19.3 and 13.5 ms, with fewer parent IDs requested. Do not attribute the full 52 ms difference between cold medians to this fix. Four cold pairs were faster and one was 6 ms slower. Warm Recent → Mine was about 7 ms slower at the median; Back was unchanged. These runs establish no warm-navigation gain. The earlier five-pair experiment showed the same startup confound and mixed warm/Back results. All samples remain in the local evidence. A hosted final-shape comparison timed out and was cancelled by closing its owned browser tab; it supplies no result. The candidate has not been deployed. Reproduce the contract and geometry check against an isolated production UI with `pnpm exec playwright test --config tests/perf/collections/playwright.config.ts parent-context.spec.ts`. Run `tests/perf/collections/measure-mine-context.ts` against baseline and candidate loopback production origins that share one disposable API, as documented in `tests/perf/collections/README.md`. Preserve upstream startup timings as controls. Required parent responses remain inside the reveal boundary. ## Risks - Explicit-ID `index` and `rows` requests use the same company, visibility and actor filters. They do not use the inbox archive filter. An archived parent is still returned by either projection. A deleted or unreadable parent is absent in both. A second index request for a failure-parent overlap would not restore missing caption data. - A failed-run task must never reuse parent-only metadata. The query key includes each projection role. Completed reads carry explicit failure-ID coverage. The tests cover overlaps, pending role changes, late heartbeat data, known absence, and transitions to empty views. - Old parent context must not override a fresh indexed parent. The current-ID placeholder filter and caption-refresh regression cover this case. - The hosted app still has unrelated server contention. This PR reduces parent request work. It does not claim to fix all hosted loading delay. Deployment acceptance should confirm the serving revision, compare matched Mine reloads and inspect errors and row stability. Revert this change if failure items or captions regress. ## Model Used OpenAI Codex, based on GPT-6, with reasoning, tool use, browser diagnostics and code execution.
