DottaandPaperclip 6dcf4160dd perf(chat): load recent messages and page history on scroll (#18358)
## Thinking Path

> - Paperclip lets people manage work done by agents.
> - A standing agent chat can hold months of conversation.
> - The chat route forced full-history mode, bypassing compact task
loading.
> - A cold visit fetched lifetime run summaries and hydrated historical
transcripts.
> - This PR starts with 20 recent messages and loads earlier pages on
upward scroll.
> - It preserves the reader's position, current questions, and draft
while history grows.

## Linked Issues or Issue Description

**What happened?**

Standing agent chats forced full-history loading. A long conversation
fetched full activity and run history before it became readable. Earlier
comments also used an explicit load control.

**Expected behavior**

Open a small recent conversation quickly. Load older messages when the
reader scrolls upward. Show an inline loading state. Keep the visible
message and composer mounted through paging, live updates, and Back
navigation.

**Steps to reproduce**

1. Open a standing agent chat with hundreds of messages and completed
runs.
2. Use a fresh browser query cache.
3. Observe full activity and run reads plus transcript requests for
historical runs.
4. Compare the recent window and upward paging after this change.

Related work: #18312 and #18323 restored compact task and collection
loading. #14848 added reopening of visited agent chats. A GitHub search
found no open PR for this chat-history optimization.

## What Changed

- Return 20 contiguous recent comments for standing chats, with a stable
oldest cursor. Keep the existing compact task exchange contract. Use the
existing company/issue/time index for cursor reads.
- Keep chats compact even if their task view previously expanded
history. Retain observed messages through live catch-up and cache-backed
return visits.
- Keep fetched history pages, acknowledged sends, and the observed
recent cursor separate. Reconcile live replies without losing history
after a send or deleted cursor.
- Hydrate metadata only for newly revealed message/run IDs; preserve
prior batches while paging. Slow-send recovery refreshes the recent
window. Receipts failures have an independent retry.
- Hydrate run summaries only for loaded messages and the latest turn.
Validate batches of at most 100 run IDs and keep the existing
issue/company access rules.
- Reuse hydrated terminal native streams when only history membership
changes. Preserve retry, resume, mode changes, reconnect recovery, and
interrupted recovery reads.
- Load older messages, decision receipts, and task handoffs through
upward scrolling. Support wheel, touch, and keyboard input. Keep pending
questions visible.
- Reserve a status slot while loading. Preserve a logical message anchor
and the mounted composer. Pause failed page reads until an inline Retry.
- Add database, route, controller, and scroll regressions, plus an
opt-in production-build browser rig for long chats on desktop and
mobile. Update design and feature/access documentation.

## Verification

- The real PostgreSQL cold-open suite passes all 12 tests, including
contiguous pages with equal timestamps, complete history, company
denial, and scoped run IDs.
- Activity route and OpenAPI suites pass 53 tests. The route run allowed
local cold-import overhead; CI retains the repository's normal timeouts.
- Three new paging regressions fail against the unchanged source. The
candidate's focused paging/window suite passes 26 tests. Broader UI
verification is recorded below when complete.
- Desktop and mobile browser acceptance covers recent-only startup,
per-frame reveal geometry, delayed and failed older pages, stable
reading anchors and drafts, Back, older comment links, and one persisted
live reply.
- Full workspace typecheck and build passed locally. The final UI source
also passes its typecheck and production build.
- Affected UI suites pass: 212 controller/history/paging tests, 352
thread/scroller tests, 26 native-stream tests, plus metadata batching
and live-cache hydration coverage. The issue mutation/access route suite
passes 179 tests.
- All 22 final desktop/mobile browser journeys pass, including delayed
image growth. The isolated second-page request proof also passes six
repeated desktop/mobile runs. A separate 6,000-message, 3,000-run
fixture passes cold-open and delayed-paging checks on both screen sizes,
still opening 20 messages and loading one 50-message page.
- Final matched production timings use baseline `aa58fa1073`
(`index-BaRiMbxd.js`) and candidate UI source `f9a26b9783`
(`index-DPWTbsFF.js`, identical application source at final head
`bf71ffd5af`). Chromium 151.0.7922.34, 1440×900, 4× CPU throttle, no
added network latency, browser HTTP cache disabled, fresh application
cache for each cold visit. Both variants block service workers and use
the same warm local API server and immutable 600-message/300-run
fixture. Only document HTML is intercepted for both variants; API
requests are real. The common API revision is `109981f8c1`; subsequent
commits change only UI and tests.

| Usable conversation | Baseline median (range) | Candidate median
(range) |
| --- | --- | --- |
| Cold direct URL | 6.57 s (5.69–7.45) | 3.07 s (2.50–3.28) |
| Warm in-app return | 3.76 s (3.54–4.76) | 0.67 s (0.58–1.46) |
| Back return | 2.53 s (2.12–4.20) | 0.51 s (0.47–1.18) |

Five pairs alternate order. Every paired difference favors the candidate
for all three journeys. Readiness requires a revealed, fully visible
latest reply above the composer and an editable composer. Return timing
starts after the Tasks route renders. Cold API requests fall from
953–954 to 71; API wire bytes fall from 517–559 KB to about 49 KB.
Separate CPU profiles and request waterfalls confirm the removal of
lifetime event hydration and are excluded from the five timing pairs.
Both variants have the same expected missing optional plan document
(404) and no browser exceptions. Control recent-window API reads have
medians of 37 ms / 32 ms, with shared-host outliers up to 376 ms.

The 6,000-message recent-window SQL uses
`issue_comments_company_issue_created_at_idx` (22 index rows read for a
21-row probe). Geometry assertions retain a 2-pixel tolerance for the
reading anchor and first-reveal layout. These are local synthetic
measurements, not deployed staging latency. Earlier timing probes are
excluded because they did not isolate service workers or composer
clearance. Final head `bf71ffd5afb5684ba9105a3127f617e7adf5139c` has 55
successful checks, three optional skips and one neutral result, with no
failures or pending checks. Greptile is 5/5 with no open review
findings.

### Failure record

Early local attempts exposed an unconditional scroller wrapper that
changed the old task layout, and automatic retries on chat page
failures. Both were corrected. The original task scroller structure
stays in place. Metadata request assertions wait for initial connection
recovery to settle, then verify only the new page’s reads;
retry/resume/reconnect revalidation remains intentional.

The initial review caught a send-before-scroll cache defect; its
controller regression failed before the fix. Later rapid-paging checks
caught scroll readiness being gated by metadata after the first reveal;
readiness now stays enabled once revealed. Live replies use the separate
acknowledged-message cache, then catch up from the server cursor.

Visual review exposed a pagination wrapper bypassing existing composer
clearance. The body is again a direct scroller child; cold-open browser
checks require the full latest reply above the composer. A
resize-observer regression failed before the fix and now passes.
Controlled delayed inline images prove both pinned following and a
stable reading anchor on desktop/mobile.

The first performance fixture lacked valid native event envelopes and
caused missing-log fallbacks. It is excluded from latency claims. The
final fixture uses saved native assistant events and conversation
session generations. The live test uses a temporary fixture-agent key,
attributes the reply to an existing synthetic run, and revokes the key.
It starts no model or agent process.

Local database attempts failed during a Docker shutdown. The retained
disposable database was restored and its suite passed. Early fixture
errors included a missing conversation identity field and session
generation. Mobile test setup also selected an offscreen sidebar link
and reused queued human input. Optional announcements could intercept
input; the fixture now dismisses them before the journeys. The scroll
observer now waits for the delivered wheel event and settled animation
frames, including when the viewport is already at the top. A
concurrently running live test briefly changed another probe’s row
count; the final acceptance and timing runs were sequential on separate
fixtures. The final rig uses the visible mobile navigation and a saved
agent reply. Anchor observation waits for the user's scroll to settle
before measuring the effect of live updates.

The full local `pnpm test:run` attempt hit repeated embedded PostgreSQL
initialization failures and failures in untouched native-session
executor suites; it was stopped after the repeated environment failures.
The targeted real-PostgreSQL suite passed, and final-head CI is required
before handoff. The first CI run also caught an exact mock expectation
missing the added company scope; the expectation is updated and its
179-test suite passes. The final-head first CI attempt also stalled an
assigned child task in the existing plan-approval scenario, then hit a
heartbeat-run row lock timeout during fixture cleanup. The failed shard
and aggregate check passed on an unchanged rerun of the same commit.
Scenario assertions and timeouts were unchanged. The failure and rerun
are retained in [CI run
41116120430](https://github.com/paperclipai/paperclip/actions/runs/41116120430).

## Risks

- Historical transcript diagnostics no longer load on a cold chat open.
Saved messages and conversation events remain available; diagnostic run
views keep their full records.
- Cursor paging must not omit comments with equal timestamps. Database
tests cover timestamp/UUID ordering and the complete set.
- Prepended or late content can move the reader. Browser checks cover
retained row identity, viewport offsets, mounted drafts, and Back.
Previously loaded pages stay in the query cache for its existing
lifetime.
- Local synthetic evidence does not establish deployed staging latency.
This PR does not merge or deploy the change.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, tool use, and code
execution. The exact backend deployment ID and context window were not
exposed in this session.

DottaandPaperclip 5a7a6b32ba fix(ui): restore compact Coordinator task loading and responder continuity (#18312)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - People open tasks from their personal workspace and send replies to
agents.
> - Cold task opens should load recent conversation before older
history.
> - Classic settings could expand history before the Coordinator
preference arrived.
> - Coordinator lists also read full tasks, and response startup used
the previous assignee.
> - This pull request restores compact reads and keeps the selected
responder visible through runtime discovery.
> - People can read and reply without waiting for unrelated history or
losing response feedback.

## Linked Issues or Issue Description

Related: #17593, #17751, #17756, #17885, #17983, and #18092.

**What happened?**

A cold task could select Classic full history while its personal
workspace preference was pending. The full-history choice stayed cached
after Coordinator became active. Coordinator Tasks used full task reads.
Needs attention fetched one enriched task per pending task.

Sending to a newly selected agent could show no responder, show the
previous assignee, or clear feedback when assignment changed. Legacy
runtime discovery then replaced the startup identity with a generic
activity line.

**Expected behavior**

Wait for the workspace preference before selecting Classic history. Show
the task instruction and recent conversation with **More messages** for
older content. Read collection indexes and fetch diagnostics for visible
rows. Keep the selected responder mounted from Send through saved input
and runtime startup.

**Steps to reproduce**

1. Enable Classic task UI and Coordinator. Delay the personal workspace
preference on a cold task open.
2. Open Coordinator Tasks or its Needs attention view with many pending
tasks.
3. Open a task assigned to a person. Select another agent in the
composer and send a message.
4. Let the message save before runtime reads return. Then allow a legacy
run to appear.

## What Changed

- Wait for task interface settings before persisting Classic history
expansion.
- Use lightweight indexes for Coordinator Tasks. Resolve pending task
IDs in batches of at most 100. Keep search and participant filters on
the server. Enrich at most 50 visible rows through the existing hook
without replacing list membership or order.
- Preserve an error when a pending task cannot load, instead of showing
a false all-clear.
- Register board cards for row enrichment. Observe newly mounted cards
after column expansion or pagination, and track visibility by element so
hidden list rows cannot clear visible board cards with the same task ID.
- Track the recipient of each submitted message through reassignment. A
later draft's recipient does not change the response already starting.
- Share a stable response header across startup, native runtime, and
legacy runtime rendering. Keep the existing transcript renderers.
- Add regression tests, production-browser checks, design guidance, and
feature-map notes.

## Verification

- Red/green: delayed Coordinator preference started a full comments read
before the fix. It now retains compact history and still expands on
request.
- Red/green: sends from human or other-agent assignment showed no
identity or the wrong identity. Both now retain the selected responder
through assignment, acknowledgement, later draft selection, and
native/legacy startup.
- In a 105-task Needs attention fixture, the previous code made 105
enriched detail requests. The fixed code makes two bounded index
requests.
- All 659 final affected tests pass across task detail, thread, runner
turn, history window, Inbox, board, row enrichment, and Coordinator
collection suites.
- Review follow-up: the production board lost its next-step badge before
card registration. The regression now passes, along with column
pagination. The focused 82-test enrichment run and 371-test
header/thread run also pass.
- All 12 compact-startup browser checks pass against the production UI
and an isolated PostgreSQL container. They cover delayed preferences,
list navigation, saved-card geometry, document/comment anchors, history
expansion, draft retention, retry, and actual legacy process startup.
The final deterministic process case recorded 118 frames with zero
missing or replaced responder identities. It does not call a model
provider.
- Full workspace build and typecheck pass. Final UI build and typecheck
pass after the shared-header change. Token gates, map checks, module
boundaries, and diff checks pass.
- The full UI rerun before the board review follow-up passed all 10,034
tests across 844 files. The 659 affected tests pass after that
follow-up. The first full UI run passed 10,030 tests and timed out in
one unchanged IssuesList large-tree test. Its two variants pass in an
isolated rerun and in the full rerun. Those later passes establish
recovery; the earlier timeout's cause remains unproven.
- The full `pnpm test:run` attempt was stopped after repeated embedded
PostgreSQL initialization failures in server fixtures. No complete local
server-suite pass is claimed. Browser verification recovered with a
disposable container database.
- A later avatar browser rerun reused the previous same-title task and
its cancelled run through the existing 48-hour title deduplication. That
fixture never reached fresh runtime startup. The test now uses a unique
title and checks its initial assignment/status; a full 12-case rerun and
a second avatar run on the same instance pass. The failed trace is
retained locally.
- Final commit `7a18372da3` has 55 successful checks, two intentionally
skipped Storybook checks, and one neutral Paperclip Review. All required
verification gates are green. Greptile is 5/5 with no actionable
findings or open review threads. The advisory Paperclip review paused
without a complete assessment; no passing Paperclip assessment is
claimed.
- These checks establish bounded reads and stable rendering. No reliable
staging latency benchmark or staging deployment is claimed.

## Risks

- Collection projections omit task bodies. Detail navigation must retain
its normal core/full task reads. Search remains server-side.
- Startup feedback must end on rejection, unavailable agents, terminal
outcomes, or a visible run. Existing cases cover those transitions.
- The shared header changes the legacy live-turn layout to retain
identity beside its existing status line.
- No migration, mutation permission, provider protocol, or execution
authority change.

## Model Used

OpenAI Codex, GPT-6 family. The exact serving deployment ID and
context-window size are not exposed in this session. The model used
reasoning, code editing, shell tools, automated Chromium checks, and
manual browser inspection.

DottaandPaperclip 7e27bc5007 fix(tasks): keep anchored opens compact and stabilize saved cards (#18092)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Task pages must make the current instruction and recent conversation
readable quickly.
> - Compact startup avoids reading all earlier messages and run
activity.
> - Every URL fragment previously selected the full-history path, even
for documents.
> - Saved document cards also arrived after the conversation was
visible. PR statistics could add another row later.
> - This pull request keeps anchors compact and reveals the saved
conversation structure together.
> - The benefit is stable reading position without loading unrelated
history.

## Linked Issues or Issue Description

Related: #17593 introduced compact startup. #14667 covers earlier reveal
and scroll work. This fix retains the bounded history contract.

**What happened?**

Opening a task document link loaded all task history. Ordinary cold
opens could reveal messages before saved document cards and plans
arrived. Later PR metadata added a statistics row and changed card
height.

**Expected behavior**

Every URL fragment keeps compact startup. Document links open their
pane. Older-comment links fetch only the target comment. Saved cards
keep their geometry after first reveal.

**Steps to reproduce**

1. Create a task with many comments, a saved plan, documents and saved
PR work products.
2. Delay the enriched task response and open the task. Observe cards
inserted after messages appear.
3. Open a document fragment. Observe full comment, activity and run
reads.
4. Delay PR metadata refresh. Observe each card grow when diff counts
arrive.

## What Changed

- Remove fragment and tab checks from automatic history expansion.
Resolve validated comment UUIDs through the authorized single-comment
endpoint, encode their path components, retain fetched targets across
document navigation, and preserve cancellation/deletion cache updates.
- Include the saved plan, document metadata and local work-product
projection in the core task read. Skip recovery, workspace and
related-task enrichment. Do not refresh providers. Summary queries no
longer select other document bodies.
- Seed saved work-product and plan queries from core, including already
pending or errored reads, without replacing known lists or an
authoritative empty result. Coordinate the bounded recent reads, saved
cards, latest transcript and settled initial pane width before first
reveal. Keep the thread and composer mounted during refresh and explicit
expansion.
- Open continuation summaries in the document pane. Reserve PR
statistics geometry while provider metadata loads.
- Add a reusable synthetic local task, nine browser checks, frame
measurements and video. Extend the PostgreSQL core-route fixture with a
saved PR row and assert its identity, URL, state and stored metadata
survive the response. Update design guidance and capability maps.

## Verification

- Red: visible document/plan cards changed from 0 to 1 to 4; thread
height grew from 690 to 1,432 pixels. Green: all seven saved cards
appear before reveal, with constant thread height and zero per-card
movement in the final reviewed browser run. The final 1,492-pixel layout
includes the reserved PR statistics lines.
- Red: delayed PR diff counts changed all three cards from 62 to 82
pixels. Green: their heights stay at 82 pixels before and after metadata
refresh.
- Nine browser journeys pass: delayed enrichment,
document/comment/unknown/continuation anchors, document clicks and
explicit history expansion with a retained draft, missing-comment retry,
delayed PR statistics, and retained older-comment position after
document navigation.
- 583 focused UI tests passed on `c91fa107ba`. After the plan-cache
follow-up, all 212 affected page/cache/plan-hook tests and UI typecheck
pass, including 14 plan-hook cases. The original 16 focused PostgreSQL
tests passed for the server changes.
- Merge-review red: holding the duplicate stored work-products read
blocked the first reveal past 10 seconds despite core already containing
the saved cards. Both empty and populated core projections now reveal
while that request remains pending. Malformed-comment tests prove no
target request is made; API tests prove path encoding and abort-signal
forwarding.
- The populated core-route test now inserts a real saved PR work product
alongside the plan and documents, then checks the complete saved
projection through HTTP. All ten task cold-open PostgreSQL tests pass.
- Plan-cache review red: an existing pending or errored plan query
prevented the saved core plan from reaching the consumer. Four real-hook
cases failed before the data-presence fix and pass afterward, for both
present and absent plans. A separately fetched newer plan or known
absent plan remains authoritative.
- Further layout red: the initial properties pane reduced visible thread
width from 775 to 742 pixels after reveal. The reveal now waits for two
stable width frames; the browser check includes width, height, card
counts and per-card geometry.
- `pnpm -r typecheck` and `pnpm build` passed for the original change;
UI typecheck and build pass after review fixes. Token, module-boundary
and map checks pass. `pnpm test:run` was stopped after about 15 minutes
in the serialized server lane. No full local test-suite pass is claimed.
On the earlier head, hosted build/typecheck and all Vitest lanes passed;
one E2E shard failed because the agent-configuration clipboard helper
copied page text into its YAML parser. On `c91fa107ba`, Greptile was 5/5
and every E2E shard passed, including the earlier clipboard case. One
unchanged Discord chat-binding test in server shard 8 returned false
after 185 ms; its 16-test integration file passes locally without
changes. The CI cause remains unestablished. On `be436ce492`, both
server shard 8 and E2E shard 7 passed without changing those tests or
their product code. On final head `e357b3bced`, all CI jobs pass,
including full general and serialized tests, all eight E2E shards,
typecheck, build and the aggregate verification gate. Exact-head
Greptile is 5/5 with no findings. The overall status rollup contains 55
successes, two intentionally skipped Storybook checks and a neutral
Paperclip Review. That advisory review ended without a complete
assessment; all previously posted findings are resolved and it added no
current findings.
- Test startup exceeded an initial 5-second deadline once while
development assets and other checks were active. The final browser
checks allow 10 seconds. These runs establish geometry and bounded
requests; they do not establish a reliable latency improvement. An
initial 503 error fixture exercised global reconnect/backoff. The
target-comment failure test uses a terminal 404.
- Browser data is synthetic. Provider metadata is simulated for the
delayed-response check. No staging deployment or live provider execution
is claimed.

## Risks

- Core task reads now include local saved-card queries and the saved
plan body. Other document bodies and all historical run activity remain
outside that path.
- First reveal waits for the bounded current structure. The existing
15-second incomplete-history fallback and inline retry remain available.
- Continuation-summary links open in the document pane in the current
task interface. Classic tasks keep their existing surface.
- No migration or mutation permission change.

DottaandPaperclip 4d92589799 perf(ui): defer hidden task rendering until history is ready (#16878)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - People open a task to read saved work and reply.
> - The conversation waits for its initial data so messages do not move
after reveal.
> - The hidden conversation and editor still render while those reads
are pending.
> - Profiling showed a useful cold-load gain when that hidden rendering
was delayed.
> - Prepare ordinary task content after its initial data is ready. Keep
the existing preparation path for comment links.
> - Keep the skeleton, measured reveal, timeout, and mounted
conversation during refresh.

## Linked Issues or Issue Description

Follow-up to #16862 and #16849. Related task-layout work: #14758.
Searches found no overlapping open rendering change.

**What existing behavior does this improve?**

Opening a task mounts hidden message rows and the rich editor while
supporting reads are still pending. These trees can render again as data
arrives before the user can see or use them.

**Subsystem affected**

UI task conversation startup and its browser acceptance suite.

**Proposed behavior**

Keep the existing skeleton and outer layout containers. Prepare the
hidden conversation and composer when initial history is ready, then use
the existing measured reveal. Keep content mounted after reveal. Hash
navigation retains eager preparation so older comment targets can be
positioned before reveal. The existing 15-second timeout still reveals
available history and the composer.

## What Changed

- Gate concealed history and composer children with the existing history
readiness, revealed-task latch, timeout, and scroll-navigation hash.
- Keep data queries, shell geometry, scroll ownership, and the reveal
frame unchanged.
- Update unit coverage for deferred content, comment-link preparation,
task changes, history timeout, and mounted editor identity during
refresh.
- Add a real browser journey that holds a background task read, retains
the same editor and draft, reloads the saved draft, sends one reply, and
checks the persisted comment independently.
- Document the loading and draft acceptance paths.

## Verification

- Repository-wide `pnpm -r typecheck` and `pnpm build` passed locally.
Token gates and all 231 task-thread unit cases passed.
- Seven regression cases failed against the old rendering behavior
before the source change.
- All 14 loading and layout browser cases passed again against the final
production UI and API build at
`15c360aa63e01ad9318aaf7865c07d1ee0d36968`. Coverage includes delayed
initial data, reading anchors, media growth, composer sizing, older
history, cold comment links, desktop/mobile same-task links and Back,
rapid switching, reduced motion, failed reads and retry, stalled
history, plan reuse, and cached-task profiling.
- The new draft journey retained the same editor during a blocked
background task refresh, restored the draft after reload, and persisted
exactly one reply.
- Final performance comparison used current master
`249ab47d41834f174ddd5e9523dc07fa8ebd8e4c` and implementation
`15c360aa63e01ad9318aaf7865c07d1ee0d36968` against the same local
160-message Markdown conversation and API process. Conditions: 50 ms
network latency, 9 Mbps down/1.5 Mbps up, 4x CPU slowdown, fresh
browsers, five alternating pairs per scenario, no CPU profiler, and no
concurrent local build/test work. Warm task navigation improved in all
five pairs: median paired saving **405 ms**; variant medians **1,787 →
1,456 ms**. Cold results were mixed: paired saving **−89 ms** (slower),
despite variant medians **3,188 → 3,021 ms**. There is no consistent
cold-load gain established by this comparison.
- Earlier prototype comparisons showed paired cold savings of 259–283
ms. Those gains did not consistently reproduce in the final comparison.
These are bounded local measurements and do not establish deployed
staging latency.
- The first prototype delayed comment-link preparation too and failed
the older-comment anchor check by 240.5 px. The narrowed implementation
keeps hash navigation on the existing eager path. That case and the full
suite now pass. The original failure trace is retained locally.
- A visual browser walkthrough read the saved conversation and plan,
restored a draft after reload, sent it once, reloaded again, and
independently checked that exactly one reply was saved.
- Greptile reviewed this exact commit at 5/5, with no actionable
findings or inline comments.
- The duplicate local `pnpm test:run` attempt was interrupted while the
same suites were completing in sharded CI so local performance could be
measured on an idle host. It is not counted as a local full-suite pass.
- All current-head [CI jobs
passed](https://github.com/paperclipai/paperclip/actions/runs/39296740548),
including the server, workspace, Runner, serialized, browser, typecheck,
build, canary, and final verification gates. The first run failed one
native-process supervision test (`preserves a real listening process and
its marker when a health RPC times out`). Its unchanged shard and
dependent gate passed on retry. The specific test also passed locally.
No source change was made for that transient failure.

## Risks

Delaying preparation can change initial scroll geometry. Hash navigation
keeps the existing preparation path because it needs the target present
before positioning. The revealed-task latch keeps refreshes from
removing history or the editor. The existing timeout still makes saved
content and the composer accessible when reads stall. No API, database,
permission, or provider changes.

## Model Used

OpenAI Codex, GPT-6, with reasoning, repository tools, code execution,
and browser verification. A more precise runtime model identifier and
context-window size are unavailable.

DottaandPaperclip d5b92cc41b perf(ui): reduce task startup initialization and redundant reads (#16862)
## Thinking Path

> - Paperclip users open tasks to read saved work and reply.
> - Faster startup must preserve message positions and composer state.
> - Chrome CPU samples showed unused shared schemas and catalog indexes
being initialized before task content.
> - The shared package exports definitions and module-local data, with
no required import-time registrations.
> - Let the browser bundler discard unused shared modules.
> - Readiness marks also exposed a duplicate plan read even though full
task detail contains that plan.
> - Keep both improvements measurable through CPU profiles, gate
transitions and real browser acceptance.

## Linked Issues or Issue Description

Follow-up to #16849. Related layout work: #14758. Searches found no
overlapping plan-cache PR.

**What existing behavior does this improve?**

Task startup evaluates unused schemas and catalog indexes reached
through the shared package barrel. The task also waits for a second
plan-document request after full task detail arrives, even when that
response already includes the plan or an explicit absent-plan value.
Profiling showed that removing the request alone gave a small and
variable total gain; unused initialization was the larger cold-load
opportunity.

**Subsystem affected**

Board task loading, shared-package bundling metadata, plan-query
caching, and local issue-detail profiling.

**Proposed behavior**

Discard unused shared modules during browser bundling. Fill an unused
plan query when a full task response arrives. List-only snapshots keep
their normal plan fetch. Keep the existing coordinated reveal.

## What Changed

- Declare the shared package side-effect free so the bundler can drop
unused module initialization. Used schemas and catalog data still
initialize normally.
- Seed an absent plan query at the successful full-task HTTP response
boundary. Use a 30-second plan-query freshness window. List cache merges
do not update this plan cache, and a later detail response never
overwrites an existing plan query.
- Preserve document-scope invalidation for plan creation, edits and
deletion.
- Add opt-in Chrome CPU profiles and readiness transitions to the
existing performance harness. Diagnostic runs use one sample per
scenario/profile and are labelled separately from latency benchmarks.
- Record only fixed gate names and readiness booleans in local browser
marks. Reset the gate effects on task changes so fully cached navigation
is profiled too.

## Verification

- Production UI build, UI typecheck and token design gates passed.
- 258 focused unit tests passed. The final freshness follow-up passed 14
tests, including query eviction followed by a list refresh, preserving a
separately fetched newer plan, missing projection, task isolation, and
document-event refresh/deletion.
- Two focused reuse tests fail with the original HTTP cache function and
pass with the fix. The original production browser case makes redundant
plan reads and fails.
- All 13 final browser cases passed serially: eight layout scenarios,
four plan-present/absent and direct/list startup cases, and a
cached-task switch that records every gate. The cached-switch case
failed before the identity dependencies were added.
- One earlier concurrent browser run failed a properties-resize
reading-anchor assertion. Two isolated repeats and the final serial
suite passed. This outlier is retained in the local logs; it was not
treated as a reason to change the unchanged scroll owner speculatively.
- Actual CPU samples and readiness artifacts were captured on a
disposable local production preview. This is browser timing data, not
exported telemetry.
- Audited 247 non-test shared modules for required import-time
registration. The four top-level loops construct exported local catalog
data. No required registration or side-effect-only shared imports were
found.
- A compiled browser-library contract accepted valid task input,
rejected an empty title, retained all seven agent statuses, and retained
GitHub metadata plus 1,576 catalog entries. All 13 browser scenarios
passed against the initialization candidate too.
- Plan reuse alone did not establish a reliable total gain: a final
local run was 4,356 ms cold and 1,116 ms warm on Fast 4G/4x CPU.
- The next five-sample run with unused shared initialization removed
measured **3,298 ms cold (24% faster)** and 1,079 ms warm. Median issue
API server time was 35 versus 39 ms. First contentful paint fell from
2,808 to 1,648 ms. JavaScript before content fell from 1,722 to 1,670
KiB; CPU initialization mattered more than byte size.
- Final alternating comparison: five samples per variant for both cold
and warm navigation, same persisted task and Fast 4G/4x CPU settings,
fresh browser per sample, order alternated between variants. **Cold
content paint: 4,588 → 3,688 ms (20% faster). Warm: 996 → 1,030 ms (+35
ms).** No CPU profiler was active. The final initialization commit is
the only source difference between these two builds.
- These local measurements do not establish deployed staging latency or
a speedup across every profile. Unthrottled timings varied with API
latency.
- Actual UI walkthrough on the final bundle: read the saved plan and
conversation, submit one unassigned reply, refresh, navigate to Projects
and Back, and inspect the new-task dialog. The reply persisted exactly
once, confirmed independently through the comments API. No paid agent
was woken.
- Final head `a7043c474d`: Greptile 5/5, all review threads resolved,
and all 56 checks passed, including full typecheck, build, unit and E2E
suites.


## Risks

Bundlers can discard unreferenced shared modules. Future required
registrations or global initialization must be declared in the package
side-effects metadata. Current module-local catalog construction remains
when its exports are used.

Merged list snapshots can retain old plan fields while receiving a new
task-cache timestamp. This change seeds only from a new full HTTP
response, rather than inferring plan freshness from those merged
snapshots. Existing plan-query state is never overwritten. List-only,
stale, invalidated, or incomplete data still uses the normal plan read.
Existing document invalidations refresh the query. No API, database,
permission or reveal-policy changes.

## Model Used

OpenAI Codex, GPT-6, with reasoning, repository tools, code execution
and browser verification. A more precise runtime model identifier and
context-window size are unavailable.

DottaandPaperclip fa50cab568 perf(ui): speed task loading without shifting the conversation (#16849)
## Thinking Path

> - Paperclip's board should open a task quickly while keeping its
conversation and composer stable.
> - The browser currently downloads unrelated screens and unopened
dialog implementations before task content appears.
> - Splitting routes alone creates many shared requests and did not
improve measured cold loading.
> - This change groups the startup and task dependency trees, preloads
the task chunk, and defers optional routes and dialogs.
> - Existing coordinated history reveal stays intact so late data does
not insert content above the reader.
> - Hidden routes must not overwrite saved scroll positions with
zero-height geometry.
> - Repeated browser measurements and delayed-response tests establish
the result independently of bundle-file size.

## Linked Issues or Issue Description

Refs #14758. Related prior work: #10463 and #14727.

**What existing behavior does this improve?**

Cold task-page opening downloads and evaluates code for other screens
and globally mounted, unopened dialogs. A direct task link should reach
its saved conversation sooner without moving already-visible messages or
the composer.

**Subsystem affected**

Board UI startup, route boundaries, dialog loading, task scroll
restoration, and the issue-detail performance harness.

**Proposed behavior**

Load optional screens and dialogs when needed, keep startup requests
bounded, and preload the task route. Preserve the current history reveal
policy. Keep the shell mounted during route loading and preserve the
reader's position when a route is temporarily hidden.

**Additional context**

The older bundle-splitting attempt in #10463 is still open from August.
This implementation targets current master and deliberately preserves
today's editor, composer, and transcript reveal behavior. It does not
implement the alternative transcript-row design discussed in #14758.
ROADMAP.md does not describe overlapping startup-bundle work.

## What Changed

- Lazy-load board routes, standalone screens, the legacy layout,
onboarding, and unopened create dialogs.
- Keep activated dialogs mounted across close/reopen to retain their
existing draft lifecycle.
- Group startup and issue dependencies and preload the emitted issue
chunk from the production HTML.
- Contain route loading within the shell and retain existing chunk-error
recovery.
- Contain dialog import failures locally, support cancellation, and keep
setup dismissed after a late download. Warm the task module from task
lists and keep the small chat redirect eager.
- Wait for task-creation dialog fields in the browser fixture before
filling an explicit title.
- Ignore zero-height scroll geometry while a route is hidden.
- Reuse the same persisted performance fixture between builds, record
actual network spans, and distinguish concealed loading content from the
ready thread in browser assertions.

## Verification

- Production UI build and UI TypeScript check passed.
- Recovery follow-up: 74 focused UI tests passed; the cancellation
change passed 23 focused tests plus all 131 onboarding tests (the latter
with a 15-second per-test timeout on the contended local host).
- Setup cancellation was reproduced against the prior production build
and verified fixed after releasing the held real wizard download.
- 91 focused UI tests passed; the final route registrations were checked
again after making standalone screens lazy (33 routing tests passed).
- All eight real-browser layout scenarios passed: delayed comments, late
media, properties changes, growing drafts, older history, Back
navigation, deep links, desktop/mobile same-task links, request
failure/retry, and stalled native/log reads.
- Browser walkthrough: read a populated task, submit one reply, refresh,
navigate to Projects, and return. The reply persisted once and the
normal composer remained usable.
- Token design gates passed. The separate repository-wide publish-token
scan fails on pre-existing references to the local maintainer username
in unchanged files; this change adds none.
- Production-build measurements use the same persisted task, local
API/database, fresh browser contexts for cold opens, and five samples
per scenario/profile. These measurements do not establish deployed
staging latency.
- Final head `076466816a`, consecutive before/after production builds:
five samples per scenario/profile, same saved task and server. Cold Fast
4G/4x CPU content paint: **5,775 → 4,248 ms (26%)**; issue API server
timing was 23 ms in both sets. Warm Fast 4G: 989 → 971 ms. JavaScript
transferred before content: **2,596 → 1,722 KiB (34%)**.
- Unthrottled cold content paint: 1,306 → 676 ms; warm: 269 → 224 ms.
These local timings vary with host load. Earlier measurements showed
about 20% cold improvement, and a contended intermediate run had
substantially higher API latency; those runs are retained in the local
evidence. The final matched pair meets the proposed 25% target, but it
does not establish a guaranteed 25% improvement across environments.
- All four browser scenarios that failed on the first CI run passed
locally after the readiness fixes; the subsequent CI run passed all
eight browser shards.
- Fault-injection browser checks: delayed route loading preserves shell
geometry; a failed route recovers through Back; cancelled or failed
dialog loading preserves an unsent reply; Back dismisses pending setup
and contains its late failure.

- Final head `076466816a`: all CI gates green (55 successful checks, no
pending or failed checks); Greptile 5/5 with no actionable findings and
all review threads resolved.

## Risks

- Dynamic chunks add a loading state on first entry to optional screens
and dialogs. Route failures use the existing error boundary. Optional
dialog failures are dismissible without unmounting the board; retrying a
rejected import requires a reload.
- The task preload prioritizes the primary board journey, including when
another screen is opened first.
- Chunk grouping should be revisited when the dependency graph changes;
bundle size alone does not establish a speedup.
- No API, authorization, migration, editor semantics, or
transcript-reveal policy changes.

## Model Used

OpenAI Codex, GPT-6, with reasoning, repository tools, code execution,
and browser verification. The runtime does not expose a more precise
model identifier or context-window size.

Dotta e3eed3a3ae Keep browser startup explicitly opt-in (#12435)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The CLI can save a configuration and start the local server in one
command.
> - The onboarding path set a browser-open environment variable without
an explicit user request.
> - Headless test servers use the same onboarding path.
> - Each server restart could therefore open a system browser.
> - This pull request removes the implicit browser-open request and
fixes test servers to disable it explicitly.
> - The benefit is predictable foreground and test startup without
unsolicited browser windows.

## Linked Issues or Issue Description

This is stack 11 of 11. It depends on stack 10.

**What happened?**

`paperclipai onboard --yes --run` set `PAPERCLIP_OPEN_ON_LISTEN=true`.
Headless server users, including browser test runners, opened the system
browser on each server restart.

**Expected behavior**

Server startup must not open a browser unless the caller explicitly sets
`PAPERCLIP_OPEN_ON_LISTEN=true`.

**Steps to reproduce**

1. Run `paperclipai onboard --yes --run` from a clean source checkout.
2. Wait for the server to listen.
3. Observe that the default system browser opens.

**Paperclip version or commit**

Reproduced on `dbf052577` plus the dependent stack.

**Deployment mode**

Local dev from source.

## What Changed

- Stop onboarding from setting `PAPERCLIP_OPEN_ON_LISTEN=true` for
foreground startup.
- Set `PAPERCLIP_OPEN_ON_LISTEN=false` in E2E and issue-detail
performance test servers as defense in depth.
- Preserve the existing explicit environment opt-in in the server.

## Verification

- `pnpm exec vitest run cli/src/__tests__/onboard.test.ts` — 10 tests
passed.
- `pnpm --filter paperclipai typecheck` — passed.
- `pnpm -r typecheck` — passed on the stacked head.
- `pnpm build` — passed on the stacked head.
- Playwright was not run locally by request.

## Risks

- Low risk. The only behavior change removes an unsolicited side effect.
- A caller that wants browser startup can still set
`PAPERCLIP_OPEN_ON_LISTEN=true` explicitly.
- No database or migration change exists in this layer.

2494a2a0fe perf: add repeatable issue-detail baseline rig (#10409)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The issue detail page is a core operator surface where perceived
latency directly affects task navigation
> - Performance work needs repeatable evidence so later optimizations
can be compared against the same scenarios
> - The page did not expose stable user-timing marks for its header or
first useful content
> - There was also no isolated seeded browser rig that measured warm
navigation, cold deep links, waterfalls, or server time
> - This pull request adds the instrumentation and a one-command
Playwright baseline harness
> - The benefit is that issue-page performance changes can be validated
with reproducible median measurements instead of anecdotes

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting: `ui/`, `server/`, and browser performance tooling.

**Problem or motivation**

The issue detail page performs a large client bootstrap and request
fan-out, but the repository lacks stable user-timing boundaries and a
repeatable benchmark. That makes performance changes difficult to
compare and allows regressions to be judged from anecdotes instead of
consistent evidence.

**Proposed solution**

Add stable header/content paint measures, development/QA-only lifecycle
vital reporting, aggregate server timing for the issue endpoint, and a
seeded Playwright command that runs warm/cold scenarios under throttled
and unthrottled profiles with N≥5 median reporting.

**Alternatives considered**

Ad hoc DevTools recordings were rejected because they are not repeatable
or reviewable. Production telemetry was rejected because this baseline
should not change production data collection. A unit-only harness was
rejected because it cannot capture browser bootstrap, rendering, and
network waterfall costs.

**Roadmap alignment**

The roadmap calls for agent performance to be measurable over time. This
change applies that evidence-first principle to a core operator page and
does not duplicate a listed roadmap deliverable.

**Additional context**

The generated report includes warm and cold medians, TTFB/FCP/LCP where
applicable, request and byte totals before first useful content,
JavaScript bytes, and issue endpoint server timing.

## What Changed

- Added `issue-detail:navigate→header-paint` and
`issue-detail:navigate→content-paint` user-timing measures to the issue
detail page.
- Added development/QA-only TTFB, LCP, and INP console reporting without
production telemetry delivery.
- Added `Server-Timing` for `GET /api/issues/:id`.
- Added `pnpm exec playwright test --config
tests/perf/issue-detail/playwright.config.ts`, which seeds an isolated
instance and runs N≥5 warm/cold samples under unthrottled and Fast 4G/4x
CPU profiles.
- Added Markdown, raw JSON, and Chrome-trace outputs with median
baseline tables and waterfall data.

## Verification

- `pnpm --filter @paperclipai/ui typecheck`
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm check:token-gates`
- `npx playwright test --config
tests/perf/issue-detail/playwright.config.ts --list`
- `pnpm exec playwright test --config
tests/perf/issue-detail/playwright.config.ts` — passed 20 samples in 9.4
minutes (5 runs × 2 scenarios × 2 profiles) for the baseline;
post-review integrity reruns also exercised the corrected paths, while
this shared runner intermittently killed Chromium processes, so the rig
now performs one bounded browser-crash retry per sample.
- Baseline medians: warm unthrottled 278/447 ms header/content; cold
unthrottled 646/646 ms; warm throttled 1240/2060 ms; cold throttled
3932/3933 ms.

## Risks

- Low product risk: the new browser measurements are development/QA
tooling and the UI timing work does not change visible layout.
- `Server-Timing` exposes only aggregate handler duration, not query
contents or private identifiers.
- Native INP reporting uses supported browser event timing entries and
silently no-ops where unsupported.

## Model Used

- OpenAI Codex, GPT-5.4, tool-assisted coding and browser execution with
reasoning enabled; context-window size is not exposed in this
environment.
