## 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

## 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

Replace single retentionDays with a three-tier BackupRetentionPolicy:
- Daily: keep all backups (presets: 3, 7, 14 days; default 7)
- Weekly: keep one per calendar week (presets: 1, 2, 4 weeks; default 4)
- Monthly: keep one per calendar month (presets: 1, 3, 6 months; default 1)
Pruning sorts backups newest-first and applies each tier's cutoff,
keeping only the newest entry per ISO week/month bucket. The Instance
Settings General page now shows three preset selectors (no icon, matches
existing page design). Remove Database icon import.
Compress database backups with gzip (.sql.gz), reducing file size ~83%.
Add backup retention configuration to Instance Settings UI with preset
options (7 days, 2 weeks, 1 month). The backup scheduler now reads
retention from the database on each tick so changes take effect without
restart. Default retention changed from 30 to 7 days.
Compare Buffer byte lengths instead of string character lengths before
timingSafeEqual to avoid potential mismatch with multi-byte input.
Add comment explaining the hubSignatureHeader ?? signatureHeader fallback.

Adds two new webhook trigger signing modes for external provider
compatibility:
- github_hmac: accepts X-Hub-Signature-256 header with
HMAC-SHA256(secret, rawBody), no timestamp prefix. Compatible with
GitHub, Sentry, and services following the same standard.
- none: no authentication; the 24-char hex publicId in the URL acts
as the shared secret. For services that cannot add auth headers.
The replay window UI field is hidden when these modes are selected
since neither uses timestamp-based replay protection.
Closes#1892

Use GREATEST(counter, MAX(issue_number)) + 1 when incrementing the
company issue counter. This self-corrects any desync between the
companies.issue_counter column and the actual max issues.issue_number,
preventing duplicate key violations on the identifier unique index.
Fixes#2705
- Plugin loader: install/reload/remove/reinstall external adapters
from npm packages or local directories
- Plugin store persisted at ~/.paperclip/adapter-plugins.json
- Self-healing UI parser resolution with version caching
- UI: Adapter Manager page, dynamic loader, display registry
with humanized names for unknown adapter types
- Dev watch: exclude adapter-plugins dir from tsx watcher
to prevent mid-request server restarts during reinstall
- All consumer fallbacks use getAdapterLabel() for consistent display
- AdapterTypeDropdown uses controlled open state for proper close behavior
- Remove hermes-local from built-in UI (externalized to plugin)
- Add docs for external adapters and UI parser contract
