DottaandPaperclip 5061ab7b35 perf(ui): speed up task and inbox cold opens (#17756)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Task lists and inboxes are the main entry points to that work.
> - Cold opens fetch overlapping task lists, task descriptions, and run
details before useful rows settle.
> - Independent responses can insert rows above content that a person
has started to read.
> - This pull request loads a small task index first and adds details
only for visible rows.
> - It keeps row order and geometry stable while those details arrive.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Cold opens of Tasks and Inbox, including the shared navigation badge.

**Subsystem affected**

Server list reads, shared response contracts, and the React UI.

**Current behavior**

The badge fetches full task bodies. Mine fetches several overlapping
lists. Historical diagnostics and row metadata add work before the first
useful list. A fast failed-run response can appear before task rows,
then move down when tasks arrive.

**Proposed behavior**

Load the selected inbox source and its required context together. Use an
index without task descriptions or recovery diagnostics. Fetch
diagnostic details for up to 50 visible rows. Keep skeletons, recovery
indicators, external status, and live metadata in fixed space.

**Reason and benefit**

Reduce work on a cold open and prevent loading-induced row movement. On
the same 100 local fixture tasks, the compact response was 262,441
decoded bytes and the index was 110,909 bytes. This comparison excludes
compression and is not a page latency benchmark.

**Breaking changes**

Existing full and compact responses remain available. New index/row
projections are opt-in and marked as partial data. Mine keeps its
existing most-recent-100 display limit, now selected on the server.
Existing filters and group preferences remain in the client. No database
migration.

**Additional context**

Refs: #17593. Related: #13095, #17428, #13803. This change addresses
collection overfetch and layout stability. It does not replace the
blocked-inbox query work or the database activity-index work.

## What Changed

- Add authorized index and row projections, with bounded task and parent
ID batches.
- Replace badge list downloads with unread IDs and aggregate counts.
Preserve actor privacy, dismissals, and local archive behavior.
- Load only the selected inbox source, plus bounded parent and
failed-run context. Return only relevant failures from the bounded run
window.
- Batch hierarchy reads, including at most one authorized child per
collapsed parent in one request. Collapsed markers do not consume the
expanded row budget, and partial descendant counts are not shown as
totals. Enrich visible rows without replacing membership, ordering,
titles, or read state.
- Reserve row geometry on desktop and mobile. Reveal the initial inbox
only after its sources settle. Preserve legacy task-list reads.
- Start collection module downloads during access checks. Keep partial
rows out of the task-detail cache.
- Keep ETags and concurrent request sharing for the new projections, but
skip the short server response TTL so archive undo sees fresh state.

## Verification

- On final head `ef6afb2a56`, the full CI workflow passed, including
build, typecheck, server/workspace/runner suites, and all eight browser
shards. A server shard reported **1,489 passing tests** before runner
shutdown canceled the job; its single infrastructure retry passed. Both
Greptile and Paperclip Review are **5/5**, with zero unresolved review
threads.
- The optional external **Entire Gates** check remains `unassessed`
because it has no active assessed Change for this comparison. Entire is
not set up in this checkout. The repository ruleset requires `ci /
verify` and `ci / e2e`; both passed. No gate configuration was changed.

- Passed workspace typecheck after the final API batching change. The
full production build also passed on the final commit; the exact-retry
E2E run built the shipped UI.
- Passed token gates and map validation. The final batch-preview pass
has 91 passing route/hierarchy/component tests, including privacy,
request bounds, 30 collapsed parents in one read, and a 120-child parent
alongside a sibling.
- Passed the 166-test focused UI/inbox/badge run, 47 additional UI
regression tests, and 34 issue-list route tests. The latest regressions
cover low-trust agent badge IDs, cold company selection, 30
description-only Mine matches with archive actions, retrying optional
row details, and collapsed/expanded siblings.
- The full local `pnpm test:run` spanned the rebase and reported
failures in five suites before it was stopped; it is not claimed as a
complete pass. A fresh serial rerun of all five suites passed
**452/452** tests (tool gateway, native resume, project repositories,
workspace recovery, and runner selection). Full current-commit coverage
is checked by CI.
- Real browser: delayed index and row-detail responses on Tasks and
Mine. The first placeholder and first row had the same origin and
44-pixel height. Twelve rows on each page had zero position, height, or
title-width change after recovery details arrived.
- Real browser: reviewed long titles and recovery status at a 390 by 844
viewport. Task text stays on one line and recovery uses a compact
indicator.
- Three fresh document loads per page on final commit `260893bf92`, with
HTTP cache retained on a warm local development server: Tasks
1.031–1.190 seconds; Mine 0.999–1.193 seconds. Browser-control overhead
is included. These values must not be compared directly with staging
latency or the earlier local samples taken during a full test run.
- The browser archive test exposed stale results after Undo. The new
projections now bypass the server TTL; immediate-mutation regression
tests pass. The final browser retry passed: Archive followed by Undo
restored exactly one row and the badge count.

- CI exposed a hook-order crash when company selection resolved after
the first inbox render. The hook now runs before the empty-company
return. All seven affected exact-retry and legacy-continuation browser
scenarios pass locally after the fix.
- Real browser review regressions: 97 description-only source matches
retained Archive actions; deliberately failed optional row reads
displayed a retry notice while all 12 observed row positions and heights
stayed unchanged. Retry restored the recovery indicator. Network fault
injection was removed.

- The final production build and workspace typecheck passed. Final
focused verification passed 153 UI/helper tests and 26 heartbeat privacy
route tests. Final review regressions cover newer diagnostics arriving
during the index read, reloading diagnostics when the same task ID
changes version, optional source failure/retry without hiding available
rows, and required external-status filter failure. The latest-failures
route test verifies bounded selection, agent filtering, success
suppressing an older failure, and private-run redaction.
- Real browser: deliberately failed the run source, then retried it.
Twelve available task rows kept the same position and 44-pixel height
before, during, and after retry. No loading skeleton replaced them.
Fault injection was removed.
- Hierarchy review decision: the cold-open barrier stays because
inserting ancestors or expanded children after revealing index rows
would cause layout shifts. Existing hierarchy context now survives
subsequent requests, with a regression proving a new ancestor read does
not blank the list. The bounded recursive tree read can still add
latency for unusually deep expanded trees.

- Tasks now handles a failed external-status filter with an explicit
error and Retry, suppressing a false empty state. All 52 Tasks component
tests pass, including failure-to-success retry. One existing large-tree
test timed out while workspace typechecking ran concurrently; the whole
component suite passed when rerun without that competing work. Workspace
typecheck, the full production build, and token gates passed for this
fix.

## Risks

- Saved filters and grouping still operate on the existing bounded
collection. This is not a new global server pagination model.
- Fixed row slots reduce available title width. Long titles remain
accessible through task navigation.
- Recovery and related diagnostics arrive after core rows. Their
responses cannot replace ordering fields, and stale versions are
rejected.
- Index/row requests now revalidate against current data instead of a
short server TTL. They still share concurrent reads and use ETags.
- This has not been deployed by this pull request. Staging latency must
be measured after deployment under comparable conditions.

## Model Used

OpenAI Codex, GPT-6 family. The exact runtime model ID and
context-window size are not exposed in this session. Used code editing,
terminal execution, and real-browser diagnostics.

DottaandPaperclip 0e5830887b perf: reveal task content sooner and parallelize issue reads (#14727)
## Thinking Path

> - Paperclip helps people manage AI agents and their work.
> - A task page must show saved replies quickly so a person can read the
work.
> - The title could appear while the conversation waited for unrelated
metadata and transcripts.
> - Thread requests also waited for enriched task details, while the
server read several independent fields in sequence.
> - This change shows saved content as soon as it is ready, starts
thread reads earlier, and runs independent server reads together.
> - Native event history takes priority over legacy log fallback, and
mentioned tasks load on intent.
> - Content-free timing spans make the remaining server delays visible
without recording task content.

## Linked Issues or Issue Description

**What happened?**

Task titles and properties appeared quickly, but saved conversation
content stayed hidden for several more seconds while metadata and run
transcripts loaded.

**Expected behavior**

Saved replies and the task description should be readable without
waiting for supporting history. Returning to a cached task should show
content within a frame or two.

**Steps to reproduce**

1. Open a task with saved comments and completed runs.
2. Delay the task activity and runs responses by five seconds in the
browser.
3. Observe whether saved content remains hidden until those responses
finish.
4. Navigate away and return to the task to check cached navigation.

**Paperclip version or commit**

The change was developed from `1b48e73e0` and rebased onto `44736c9c7`.

**Deployment mode**

Built from source, tested in an authenticated staging deployment and
with local response replay.

Related: #14667 overlaps the transcript reveal behavior and adds
separate retry UX. This PR also changes navigation prefetch, parent
metadata gates, native log fallback, server read scheduling, and timing
spans. #12647 proposes a separate SQL predicate optimization in the runs
service. #13597 and #13095 are earlier loading fixes.

## What Changed

- Start activity and runs when the task page mounts, alongside task
details and comments, using the route reference for shared query keys.
Hover/focus prefetch does not start full history reads.
- Reveal saved comments and descriptions while metadata and transcripts
load. Preserve strict waits for linked-comment navigation and tasks with
only runtime content.
- For settled native runs, fetch legacy logs only when event history is
empty or fails. Preserve live-log subscriptions for queued and running
native runs. Fetch mentioned-task details on hover or focus.
- Run independent issue-detail enrichment and run metadata reads in
parallel while preserving recovery dependencies.
- Add `Server-Timing` phases and opt-in OpenTelemetry spans, plus
regression tests and observability documentation.

## Verification

- **313 tests passed** across the initial seven focused component,
cache, timing, and scroll suites. After review fixes, **313 tests
passed** across five task-page, cache, prefetch, and live-transcript
suites (`pnpm exec vitest run` with `--maxWorkers=1`; these sets
overlap).
- `pnpm -r typecheck` and `pnpm build` passed locally before the final
UI-only review fixes. UI typecheck/build and `pnpm check:token-gates`
passed after those fixes. The final commit also passes full typecheck
and build in CI.
- The full local Vitest run was attempted. Several unrelated embedded
PostgreSQL fixtures failed to start, and parallel test workers hit
timeouts. Focused reruns passed. A later local full-suite rerun was
stopped after the complete CI suite passed; it is not claimed as a local
full-suite pass.
- Final commit `d1e147145`: **54 checks passed, 2 skipped**, including
all server/workspace test shards, all eight browser E2E shards, full
build/typecheck, Runner checks, release registry, and canary
clean-install verification. [CI
run](https://github.com/paperclipai/paperclip/actions/runs/36734642034).
Greptile **5/5** after two reviews; both findings fixed and all review
threads resolved. No merge conflicts.
- Live browser tests on an existing task with two saved replies: median
full reload to visible content fell from **1.92 s** (3 samples) to
**1.40 s** (5 samples). Cached return fell from **421 ms** (1 sample) to
**29 ms** (3 samples). These are observed samples, not a performance
guarantee.
- With activity and runs delayed by five seconds, saved content appeared
in **1.38 s** on desktop and **1.33 s** on mobile. The inspected comment
did not move when metadata arrived. Verified history expansion, task
properties, pending-input navigation, dashboard return, and mobile
layout.
- A separate local replay with fixed responses reduced visible-content
time from **5.12 s** to **2.15 s**. This isolates frontend behavior and
is not a live-server benchmark.

## Risks

Progressive history can change the thread after first paint. Existing
anchor behavior is retained and covered by tests and delayed-response
browser checks. Query aliases must stay aligned for invalidation.
Parallel reads can increase short bursts of database work; dependent
recovery operations remain ordered. Full reloads still depend on network
and task-detail latency.

No schema or authorization change. OpenTelemetry remains disabled
without an operator endpoint. The added spans use a closed set of phase
names and carry no task IDs, task content, or exception text.

I checked `ROADMAP.md`; this is a performance fix within the existing
task page.

## Model Used

OpenAI GPT-6 in Codex. The runtime does not expose a more specific model
ID or context-window size. The agent used reasoning, code editing,
terminal tools, and Chrome performance profiling.

DottaandPaperclip 1452d5f413 perf(ui): warm issue detail navigation (#10416)
## Thinking Path

> - Paperclip is the open source control plane people use to coordinate
AI-agent companies
> - The board UI opens issue details from lists, quicklooks, and the
inbox
> - Those navigation paths already have enough issue data to paint the
header immediately, but the comment feed still waits for its first
request
> - That delay makes repeat navigation feel cold and can briefly show an
empty thread before comments arrive
> - This pull request centralizes the comment page shape, prefetches
issue detail plus the first comment page, and renders a reserved
skeleton while an uncached page is loading
> - The benefit is faster, stable warm navigation without coupling this
change to the separate aggregate issue-detail API work

## Linked Issues or Issue Description

- **Subsystem affected:** `ui/` — React + Vite board UI
- **Problem or motivation:** Opening an issue from an already-loaded
list still waits for the first comments request and may flash the
empty-thread state, making warm navigation feel slower than necessary.
- **Proposed solution:** Prefetch the issue-detail snapshot and first
comments page from every issue navigation entry point, reuse one
page-size constant for prefetch and render queries, and show the
existing chat skeleton until the uncached initial page resolves.
- **Alternatives considered:** Relying only on detail-query prefetch
leaves comments cold; bundling this with the aggregate issue-detail
endpoint would make the UI improvement harder to review and land
independently.
- **Roadmap alignment:** `ROADMAP.md` has no overlapping
issue-navigation initiative. This is a focused board responsiveness
improvement.
- **Related pull requests:** #10409 establishes the issue-detail
performance baseline; #10414 reduces server-side issue-detail request
overhead.

## What Changed

- Added one shared issue-comment page-size constant used by rendering
and prefetching.
- Added first-page comment prefetching and a combined navigation
prefetch helper.
- Wired quicklook, issue-list keyboard navigation, and inbox navigation
to warm both caches.
- Kept the existing chat skeleton visible while the first uncached
comment page loads.
- Added focused cache behavior tests for comment and combined navigation
prefetching.

## Verification

- `vitest run ui/src/lib/prefetchIssueComments.test.ts` — 3 tests
passed.
- `tsc -b ui` — passed.
- `pnpm check:token-gates` — passed.

## Risks

- Low risk: this adds background prefetch requests on intentional issue
navigation/hover paths. React Query stale-time deduplication prevents
repeat requests while the cache is fresh.
- The change intentionally remains independent of the separate aggregate
`getView` work and composes with it through the same query keys.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex coding agent, exact model `gpt-5.6-sol`; context-window
size was not exposed; reasoning mode with repository tool use and code
execution.
