DottaandPaperclip a1f77821b9 perf(tasks): show recent conversation before historical activity (#17593)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - A task page must show the instruction and current conversation
quickly.
> - The current page waits for related task data and historical run
transcripts.
> - These reads grow with task history, even when the reader only needs
the latest answer.
> - This pull request gives cold opens a small initial view and loads
older history on demand.
> - Messages and runs observed while the page stays open remain visible.
> - The benefit is a readable task before historical diagnostics finish
loading.

## Linked Issues or Issue Description

Related: #14667 and #16229. The first changes the reveal gate and scroll
anchors. The second adds general history pagination. This PR adds a core
task read and a folded recent-conversation view. It preserves the
default full-read API contracts. The shared files will need coordination
if either related PR lands first.

**What existing behavior does this improve?**

Cold opening an ordinary task with a long conversation or large run
logs.

**Current behavior**

Task enrichment and historical transcripts delay the readable
conversation. A cold open can fetch several megabytes of tool activity
before revealing saved messages.

**Proposed behavior**

Show the task instruction, recent saved replies, latest human input, and
the latest run's conversation data first. Fetch older messages and full
run activity when the reader chooses **More messages**. Retain new
messages while the page stays open.

## What Changed

- Add an authorized core issue view that skips related enrichment. Keep
enrichment on the existing detail read. Share task mutation, rollback
and invalidation updates with the core cache.
- Add a bounded recent-comment read. Preserve the first human
instruction when no description exists, including legacy rows with a
NULL author type. Keep company and task access checks and comment
redaction.
- Add optional recent activity and run-summary views. Fetch original
input receipts for visible comments separately so delivered messages
stay out of the queue. Reconcile watched unfinished runs after a
reconnect beyond the preview window, removing deleted runs after
reconciliation.
- Filter the latest native run's initial events to assistant messages,
request lifecycles and terminal results. Full event reads remain
available on expansion. Legacy fallback reads use a small tail extended
to the first complete record. HTTP cancellation aborts the storage read.
- Retain observed messages across cursor catch-up and new runs. Apply
local cancellation and deletion to both caches and their task aliases.
Refetch locally seeded history pages on expansion. Preserve expansion
across identifier and UUID links. Keep deep links, classic tasks and
Agent Chat on their existing full-history path.
- Update API documentation, design guidance, capability maps and
regression coverage.

## Verification

- Final acceptance on `9ea0b15ae44d9f6d2c9a9f824b4835f299f92979`: all CI
gates passed, including server/UI tests, all eight browser shards,
runner checks, full typecheck and build. [Final CI
run](https://github.com/paperclipai/paperclip/actions/runs/40326990328).
GitHub reports 55 successful checks, two intentionally skipped checks,
and one neutral Paperclip Review check described below. No checks are
pending or failed; Greptile is 5/5 and no review threads remain open.
- October 26 merge update: merged current `master`. The only conflict
was in task-page imports; both the compact-history hook and the new
live-update hooks remain. All CI tests and build jobs passed on
`044fd6733d`. Fresh review found canceled-comment cache drift, legacy
human-comment filtering, send-then-expand truncation, and partial legacy
log records. These defects were fixed in `af3d66a5bd`.
- Review-fix verification: 470 tests pass across ten affected suites,
including all six PostgreSQL cold-open tests without a helper override.
Cancellation/delete and send-then-expand regression tests failed before
the fixes and pass afterward. Coverage includes task identifier/UUID
reopen, stale in-flight reads, legacy NULL author types, local-file and
object-storage tails cut inside UTF-8 text, route forwarding, and
request cancellation. Full workspace typecheck and production build,
token gates, map validation and diff checks pass.
- Follow-up review found that a failed expanded legacy read lost its
record-alignment state on retry. `9ea0b15ae4` commits the expanded
window only after a successful read. The new regression fails before the
fix and passes afterward; all 19 transcript tests, UI typecheck, UI
build and token gates pass. Greptile reviewed this commit at 5/5 with no
actionable findings, and all review threads are resolved.
- The final Paperclip Review check ended neutral because its execution
did not complete; no passing Paperclip assessment is claimed. Its
earlier four concrete findings were fixed and regression-tested.
Greptile and the security scans completed successfully on the final
commit.
- The preceding `af3d66a5bd` CI run was canceled when superseded by the
retry fix. Its server shard 11 check briefly reported failure, but the
job API records cancellation and its test step passed all 1,750 tests.
This superseded run is not used as final CI acceptance.
- 549 focused tests pass on the final implementation across nine task
UI, activity-route, OpenAPI and PostgreSQL suites. These cover pending
history, desktop/mobile visibility, expansion, retained runs, message
bursts, cancellation recovery and queued-comment removal in both views.
- Legacy expansion keeps the latest answer visible while fetching and
deduplicating older output.
- Five PostgreSQL tests pass for core access denial, recent comments,
missing-description instructions, event paging and bounded activity/run
reads. macOS could not start another PostgreSQL cluster because it
exhausted its semaphore limit. These tests used a separate disposable
database on an existing local server through a temporary test setup
override. The helper was restored afterward.
- Full workspace typecheck and build pass with the final state fixes, as
do token gates and capability-map validation.
- Token gates, capability-map validation and `git diff --check` pass.
- Browser proof used a disposable task with 80 comments and six large
run histories. The cold view showed the instruction and recent exchange.
**More messages** revealed older comments. Navigation away and back
preserved expansion.
- Local HTTP sample: core 50 ms, recent comments 24 ms, recent run
summaries 17 ms. The latest native conversation response was 839 JSON
characters / 8 ms; its full event response was 1,099,005 / 86 ms.
Browser content paint was 1.34 seconds with development assets cached.
These are local observations, not staging latency claims.
- The first CI run passed every job except four board-send browser cases
and the review threshold. Those browser fixtures only mocked the old
comments endpoint; they now serve both recent and full reads, retaining
all message and attachment assertions. Both initial review findings were
fixed with regression tests. The next CI run passed every job. The
deeper review identified core-cache mutation, older delivery receipt and
retained run-status gaps; those are now fixed with regression coverage.
Final review is 5/5 with zero unresolved findings. Final-head CI
initially failed one unchanged runner shutdown test
(`runnerd-codex-transport.test.ts`, timeout-attachment case) with
`NativeSessionCloseUnrecoverableError`; all other CI jobs passed. The
same runner code passed on 971a762f80. A targeted local reproduction
also failed during provider drain. The failure is outside the changed
task loading paths; its underlying cause remains unresolved. The single
failed-job retry passed on the same head; this demonstrates recovery,
not a root-cause fix. All CI gates passed on the previous implementation
head `9004f94f28`: [CI run and
retry](https://github.com/paperclipai/paperclip/actions/runs/40192334629).
- `pnpm test:run` was attempted and stopped after repeated embedded
PostgreSQL startup failures. The native session suite recorded 15
database-related failures; other database suites could not start. No
complete local suite pass is claimed.

## Risks

- The compact view intentionally omits older diagnostics until
expansion. Existing open questions and approvals still use the current
interaction and run paths.
- Previously observed comment and activity rows remain cached while
open. The newest preview and incoming cursor pages refresh; this does
not add a general historical-edit synchronization protocol.
- Recent views are optional. Existing full API callers retain their
response shape and behavior. No migration is required.
- A legacy tail can exceed the requested byte limit by the prefix of its
first log record. Backward reads stop at the preceding record boundary
and honor cancellation.
- Staging has not been deployed or qualified with this change. Instance
startup latency is separate from task history loading.
- The related open PRs touch the same task-history files.
