## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Reliable execution depends on heartbeat routing, issue lifecycle
semantics, telemetry, and a fast enough local verification loop to keep
regressions visible
> - The remaining commits on this branch were mostly server/runtime
correctness fixes plus test and documentation follow-ups in that area
> - Those changes are logically separate from the UI-focused
issue-detail and workspace/navigation branches even when they touch
overlapping issue APIs
> - This pull request groups the execution reliability, heartbeat,
telemetry, and tooling changes into one standalone branch
> - The benefit is a focused review of the control-plane correctness
work, including the follow-up fix that restored the implicit
comment-reopen helpers after branch splitting
## What Changed
- Hardened issue/heartbeat execution behavior, including self-review
stage skipping, deferred mention wakes during active execution, stranded
execution recovery, active-run scoping, assignee resolution, and
blocked-to-todo wake resumption
- Reduced noisy polling/logging overhead by trimming issue run payloads,
compacting persisted run logs, silencing high-volume request logs, and
capping heartbeat-run queries in dashboard/inbox surfaces
- Expanded telemetry and status semantics with adapter/model fields on
task completion plus clearer status guidance in docs/onboarding material
- Updated test infrastructure and verification defaults with faster
route-test module isolation, cheaper default `pnpm test`, e2e isolation
from local state, and repo verification follow-ups
- Included docs/release housekeeping from the branch and added a small
follow-up commit restoring the implicit comment-reopen helpers that were
dropped during branch reconstruction
## Verification
- `pnpm vitest run
server/src/__tests__/issue-comment-reopen-routes.test.ts
server/src/__tests__/issue-telemetry-routes.test.ts`
- `pnpm vitest run server/src/__tests__/http-log-policy.test.ts
server/src/__tests__/heartbeat-run-log.test.ts
server/src/__tests__/health.test.ts`
- `server/src/__tests__/activity-service.test.ts`,
`server/src/__tests__/heartbeat-comment-wake-batching.test.ts`, and
`server/src/__tests__/heartbeat-process-recovery.test.ts` were attempted
on this host but the embedded Postgres harness reported
init-script/data-dir problems and skipped or failed to start, so they
are noted as environment-limited
## Risks
- Medium: this branch changes core issue/heartbeat routing and
reopen/wakeup behavior, so regressions would affect agent execution flow
rather than isolated UI polish
- Because it also updates verification infrastructure, reviewers should
pay attention to whether the new tests are asserting the right failure
modes and not just reshaping harness behavior
## Model Used
- OpenAI Codex coding agent (GPT-5-class runtime in Codex CLI; exact
deployed model ID is not exposed in this environment), reasoning
enabled, tool use and local code execution enabled

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - A core part of that is the operator experience around reading issue
state, agent chat, and sub-task structure
> - The current branch had a long run of issue-detail and issue-list UX
fixes that all improve how humans follow and steer active work
> - Those changes mostly live in the UI/chat surface and should be
reviewed together instead of mixed with workspace/runtime work
> - This pull request packages the issue-detail, chat, markdown, and
sub-issue list improvements into one standalone change
> - The benefit is a cleaner, less jumpy, more reliable issue workflow
on desktop and mobile without coupling it to unrelated server/runtime
refactors
## What Changed
- Stabilized issue chat runtime wiring, optimistic comment handling,
queued-comment cancellation, and composer anchoring during live updates
- Fixed several issue-detail rendering and navigation regressions
including placeholder bleed, local polling scope, mobile inbox-to-issue
transitions, and visible refresh resets
- Improved markdown and rich-content handling with advisory image
normalization, editor fallback behavior, touch mention recovery, and
`issue:` quicklook links
- Refined sub-issue behavior with parent-derived defaults, current-user
inheritance fixes, empty-state cleanup, and a reusable issue-list
presentation for sub-issues
- Added targeted UI tests for the new issue-detail, chat scroll/message,
placeholder-data, markdown, and issue-list behaviors
## Verification
- `pnpm vitest run ui/src/components/IssueChatThread.test.tsx
ui/src/components/MarkdownEditor.test.tsx
ui/src/components/IssuesList.test.tsx
ui/src/context/LiveUpdatesProvider.test.tsx
ui/src/lib/issue-chat-messages.test.ts
ui/src/lib/issue-chat-scroll.test.ts
ui/src/lib/issue-detail-subissues.test.ts
ui/src/lib/query-placeholder-data.test.tsx
ui/src/hooks/usePaperclipIssueRuntime.test.tsx`
## Risks
- Medium: this branch touches the highest-traffic issue-detail UI paths,
so regressions would show up as chat/thread or sub-issue UX glitches
- The changes are UI-heavy and would benefit from reviewer screenshots
or a quick manual browser pass before merge
## Model Used
- OpenAI Codex coding agent (GPT-5-class runtime in Codex CLI; exact
deployed model ID is not exposed in this environment), reasoning
enabled, tool use and local code execution enabled

The handleChatImageClick useCallback (and its dependencies) was defined
after conditional early returns, violating React's rules of hooks and
causing "Rendered more hooks than during the previous render" crashes.

Clicking an image in a chat message now opens the same ImageGalleryModal
used by the attachments gallery. Matches by contentPath or assetId.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - The issue detail page displays comment threads with rich timeline
rendering
> - Long threads (100+ items) cause severe typing lag in the comment
composer because every keystroke re-renders the entire timeline
> - CDP tracing confirmed 110ms avg key→paint latency and 60 long tasks
blocking the main thread for 3.7s total
> - This pull request memoizes the timeline, stabilizes callback props,
debounces editor observers, and reduces idle polling frequency
> - The benefit is responsive typing (21ms avg, 5.3× faster) even on
threads with 100+ timeline items
## What Changed
- **CommentThread.tsx**: Memoize `TimelineList` with `useMemo` so typing
state changes don't re-render 143 timeline items; extract
`handleFeedbackVote` to `useCallback`; added missing deps
(`pendingApprovalAction`, `onApproveApproval`, `onRejectApproval`) to
useMemo array
- **IssueDetail.tsx**: Extract inline callbacks (`handleCommentAdd`,
`handleCommentVote`, `handleCommentImageUpload`,
`handleCommentAttachImage`, `handleInterruptQueued`) to `useCallback`
with `.mutateAsync` deps (not full mutation objects) for stable
references; add conditional polling intervals (3s active / 30s idle) for
`liveRuns`, `activeRun`, `linkedRuns`, and timeline queries
- **MarkdownEditor.tsx**: Debounce `MutationObserver` and
`selectionchange` handlers via `requestAnimationFrame` coalescing
- **LiveRunWidget.tsx**: Accept optional `liveRunsData` and
`activeRunData` props to reuse parent-fetched data instead of duplicate
polling
## Verification
- Navigated to [IP address]:3105/PAPA/issues/PAPA-32 (thread with 100+
items)
- Typed in comment composer — lag eliminated, characters appear
instantly
- CDP trace test script (`test-typing-lag.mjs`) confirmed: avg 21ms
key→paint (was 110ms), 5 long tasks (was 60), 0.5s blocking (was 3.7s)
- Ran `pnpm test:run` locally — all tests pass
## Risks
- Low risk. All changes are additive memoization and callback
stabilization — no behavioral changes. Polling intervals are only
reduced for idle state; active runs still poll at 3–5s.
## Model Used
- Claude Opus 4.6 (`claude-opus-4-6`) via Claude Code CLI, with tool use
and extended context

Image attachments now render in a 4-column grid with square aspect ratio
and center-cropped thumbnails. Clicking opens the existing gallery modal.
Hover reveals a trash icon; clicking it shows an inline confirmation
overlay before deleting. Non-image attachments retain the original list
layout.

When dragging files like .zip onto the issue description editor, non-image
files are now uploaded as attachments instead of being silently ignored.
Images continue to be handled inline by MDXEditor's image plugin.

Add childIssues to the useEffect dependency array so the Properties panel
is refreshed whenever the child issue list updates (e.g. an agent creates
or deletes a sub-task while the panel is open). Previously the panel kept
the snapshot from the initial render of the parent issue.

Move parent-task link out of the 2-column PropertyRow layout and into
a dedicated full-width section at the bottom of the panel, separated
by a Separator. Sub-tasks are listed in the same section when present.
Each item shows a StatusIcon aligned with the first line of wrapped
title text (items-start + mt-0.5 on the icon wrapper).

Display workspace branch, path, and status in a card on the issue main pane
instead of in the properties sidebar. Only shown for non-default (isolated)
workspaces. Edit controls are hidden behind an Edit toggle button.

Pills with semi-transparent backgrounds were using raw color luminance to pick
text color, ignoring the page background showing through. This caused unreadable
text on dark themes for mid-luminance colors like orange. Now composites the
rgba background over the actual page bg (dark/light) before computing WCAG
contrast ratios, and centralizes the logic in a shared color-contrast utility.
