## 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

- 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
Part A: Move executionRunId assignment from enqueueWakeup() to
claimQueuedRun() — lazy locking prevents stale locks on queued runs.
Part B: Clear executionRunId when assigneeAgentId changes in issues.ts
line 759, matching existing checkoutRunId clear behavior.
Part C: Add staleness detection at checkout path.
Fixes: 4 confirmed incidents where stale executionRunId caused 409
checkout conflicts on new and reassigned issues.
Restructure the TelemetryClient to send the correct backend envelope
format ({app, schemaVersion, installId, events: [{name, occurredAt, dimensions}]})
instead of the old per-event format. Update all event dimension names
to match the backend registry (agent_role, adapter_type, error_code, etc.).

Add the shared telemetry sender, wire the CLI/server emit points,
and cover the config and completion behavior with tests.

Timer wakes had no taskKey, so they couldn't use agentTaskSessions for
session resume. Adds a synthetic __heartbeat__ task key for timer wakes
so they participate in the full session system.
Includes 6 dedicated unit tests for deriveTaskKeyWithHeartbeatFallback.

Expose project and execution workspace runtime defaults, control endpoints, startup recovery, and operator UI for start/stop/restart flows.

Persist realized isolated/operator workspaces back onto the issue as reusable workspaces so later runs stay on the same workspace, and update the issue workspace picker to present realized isolated workspaces as existing workspaces.

mkdir -p the CODEX_HOME directory in codex-local adapter and the
agentHome directory in the heartbeat service before passing them to
adapters. This prevents CLI tools from erroring when their home
directory hasn't been created yet. Covers all local adapters that
set AGENT_HOME.

Persist child-process metadata for local adapter runs, keep detached runs alive when their pid still exists, queue a single automatic retry when the pid is confirmed dead, and clear detached warnings when the original run reports activity again.

Introduce a singleton instance_settings store and experimental settings API, add the Experimental instance settings page, and gate execution workspace behavior behind the new enableIsolatedWorkspaces flag.
