a3313f6944 fix(ui): complete read recovery and enforce query error rendering (#18822)
## Thinking Path

> - Paperclip lets people manage agent work through the board.
> - The board reads task, agent, settings, plugin, and run data from the
server.
> - A deploy can interrupt those reads after content is already visible.
> - Local error branches can replace that content with an error or show
raw codes.
> - This pull request moves the remaining reads to the shared recovery
behavior.
> - The query-error guard prevents new local error patterns from
returning.

## Linked Issues or Issue Description

**What happened?**
Loaded lists, settings, task panels, and manual reads could clear their
content or show errors during a server restart. Some reads also disabled
the shared retry policy.

**Expected behavior**
Keep loaded content during a temporary failure. Show the shared
connection banner. Retry reads after recovery. Replace content after a
real access denial or missing resource, with readable copy.

**Steps to reproduce**
Open a task, settings page, or run log. Return 503 with
`tenant_app_unavailable` from the API. Restore the API and check that
content refreshes. Repeat with 403 and 404 to check the failure state.

Related merged work: Refs #15754, Refs #15772, Refs #17960. This change
covers remaining reads and enforcement. Browser persistence and the
outage browser suite follow separately.

## What Changed

- Repair an existing PostgreSQL deadline fixture at UTC boundaries. A
daily cap defers a heartbeat until both its original interval and the
next UTC day allow it. Keep the counted run in its seeded day and cover
noon, just before midnight and the first second after midnight with
explicit clocks and real PostgreSQL. Production scheduling is unchanged.

- Integrate the saved list, settings, shell, task, and manual-read
recovery changes against current master. Preserve the current task,
Inbox, and run-log structure.
- Add `useResilientFetch` for component-local reads. Preserve loaded
data, cancel stale requests, and retry through the shared connectivity
policy. Keep browser and pairing capabilities in memory.
- Retain run log chunks across stream changes and catch up after
recovery without duplicate chunks or stalled requests.
- Keep genuine authorization and missing-resource failures visible.
Translate known single-word codes such as `forbidden`. Show known skills
and disconnected-app failures before sibling loading states. Keep Retry
bound to its failed request.
- Make the query-error guard enforce by default and run it in the CI
policy job. Document the narrow exceptions and the read recovery
contract.
- Invalidate pending OAuth discovery when the operator leaves setup or
its context changes. Keep reserved-popup cleanup bound to the current
attempt.

## Verification

- Current read head `09d1db29dea` is merge-ready: all 59 check runs are
completed (54 successful, three skipped, two neutral), the legacy Snyk
status is successful, and both required `ci / verify` and `ci / e2e`
gates pass. Greptile Apex reviewed this exact head at 5/5 with no
unresolved threads; the branch has no merge conflicts. The current CI
run is `41748339602`.
- Current read head `09d1db29dea` includes master `683fa4725e9`. The
latest change touches only the existing server deadline test fixture.
Application source remains the previously verified `86376fa751e`
revision: all 60 affected skills/disconnected-app tests and both
application UI typechecks passed, along with token gates and the
enforcing query-error guard. Those UI suites were not repeated for this
test-only repair.
- The fixture repair passes all seven deadline integration cases and the
complete server typecheck, including the server test layer. The old
assertion deterministically fails at 23:59:06.888 UTC; its
one-second-old run also fails the first-second-of-day probe. The
corrected fixture passes noon and both midnight probes. The permanent
three-case coverage uses seeded 2099 clocks.
- Twelve new regressions fail against the previous implementation. Both
skills variants and disconnected-app pages show either request's 403 or
429 while the sibling pauses or remains fetching. Permission failures
stay visible. Retry stays usable for its failed request and recovers
independently. An initial test-fixture query-key typo was corrected
before the passing run. The finding is replied to and resolved. Greptile
reviewed prior application revision `86376fa751e` at 5/5 with no new
actionable findings or unresolved threads. The current test-only head
has now received its own Apex 5/5 review with no unresolved threads, and
its CI is successful as recorded above.
- The preceding OAuth fix passed all 237 setup tests on both application
branches. Its ten regressions prove that Back, Cancel, unmount, or
context changes retire initial discovery without creating a connection,
caching old identities, navigating an abandoned popup, or closing a
newer attempt.
- Earlier master integration `e992f770339` passed all 309 tests across
eight affected Slack, recovery, retry, submission and task files, plus
UI typecheck, token gates, enforcing query-error scan and seven guard
tests. The integration preserves Slack workspace reconnect and shared
recovery, readable execution errors, source-inspection company scoping,
and current submission behavior. Newly inherited retained-file recovery
controls keep cached data through transient failures and hide it after
definitive denial.
- The preceding cache head `97c0bc3966f` passed 1,038 focused
cache/write/editor/account/task/API tests. All 22 built-UI
outage/write/loading cases passed in 4.7 minutes on exact browser head
`b7deaaee5da`, with strict checking of all three specs. The latest
skills/app rendering fix is covered by its affected component suites;
those broader cases were not repeated for this separate read path.
- Historical broader UI, CLI and build results and unresolved aggregate
server/DB/adapter failures remain in the PR discussion. Interrupted CI
runs were audited and recorded separately; they are not counted as
passes. Controlled local outages do not prove hosted authentication or a
real Cloud restart/deploy. Real hosted acceptance remains required after
merge and deployment.

Commands for the latest fix:

```sh
pnpm --filter @paperclipai/ui exec vitest run src/pages/CompanySkills.test.tsx src/pages/apps/AppNotConnected.test.tsx
pnpm --filter @paperclipai/ui typecheck
pnpm check:token-gates
node scripts/check-query-error-rendering.mjs --enforce --summary
```

## Risks

This migration touches many read surfaces. The main risks are initial
loading, request cancellation, retained authorization state, and run-log
paging. The tests cover those states. There are no server, schema,
dependency, or API contract changes. The follow-up browser suite and
hosted deploy acceptance are required before release acceptance.

Recovered commits retain their original authors. If squash-merging,
preserve `Co-Authored-By: Bender (Fable) <bender@agents.paperclip.ing>`
and the Paperclip trailer.

## Model Used

OpenAI `gpt-6.1-sol` through Codex, with xhigh reasoning effort, tool
use, and code execution. The context window size is not exposed. Saved
source commits keep their original authorship.

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.
