## Thinking Path
> - Paperclip orchestrates AI agents and company-scoped control-plane
actions for zero-human companies.
> - This change touches the server authz boundary around company
portability, approvals, activity, and heartbeat-run operations.
> - The vulnerability was that board-authenticated callers could cross
company boundaries or create new companies through import paths without
the same authorization checks enforced elsewhere.
> - Once that gap existed, an attacker could chain it into higher-impact
behavior through agent execution paths.
> - The fix needed to harden every confirmed authorization gap in the
reported chain, not just the first route that exposed it.
> - This pull request adds the missing instance-admin and company-access
checks and adds regression tests for each affected route.
> - The benefit is that cross-company actions and new-company import
flows now follow the same control-plane authorization rules as the rest
of the product.
## What Changed
- Required instance-admin access for `new_company` import preview/apply
flows in `server/src/routes/companies.ts`.
- Required company access before approval decision routes in
`server/src/routes/approvals.ts`.
- Required company access for activity creation and heartbeat-run issue
listing in `server/src/routes/activity.ts`.
- Required company access before heartbeat cancellation in
`server/src/routes/agents.ts`.
- Added regression coverage in the corresponding server route tests.
## Verification
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/company-portability-routes.test.ts
src/__tests__/approval-routes-idempotency.test.ts
src/__tests__/activity-routes.test.ts
src/__tests__/agent-permissions-routes.test.ts`
- `pnpm --filter @paperclipai/server typecheck`
- Prior verification on the original security patch branch also included
`pnpm build`.
## Risks
- Low code risk: the change is narrow and only adds missing
authorization gates to existing routes.
- Operational risk: the advisory is already public, so this PR should be
merged quickly to minimize the public unpatched window.
- Residual product risk remains around open signup / bootstrap defaults,
which was intentionally left out of this patch because the current
first-user onboarding flow depends on it.
## Model Used
- OpenAI GPT-5 Codex coding agent with tool use and local code execution
in the Codex CLI environment.

## 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

- backup-lib: delete uncompressed .sql file in catch block when gzip
compression fails, preventing silent disk usage accumulation
- server: replace stale retentionDays scalar with retentionSource in
startup log since retention is now read from DB on each backup tick
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.
On resumed sessions, skipping --append-system-prompt-file (the original
fix) left two secondary issues:
- commandNotes still claimed the flag was injected, producing misleading
onMeta logs on every resumed heartbeat
- The instructions file was still read from disk and a combined temp file
written on every resume, even though effectiveInstructionsFilePath was
never consumed
Hoist canResumeSession before the I/O block and gate both the disk
operations and commandNotes construction on !canResumeSession / !sessionId.
Adds three regression tests: commandNotes is populated on fresh sessions,
empty on resume; and no agent-instructions.md is written on resume.
On resumed sessions the agent instructions are already present in the
session cache. Unconditionally passing --append-system-prompt-file
re-injects 5-10K redundant tokens per heartbeat and may be rejected by
the Claude CLI when combined with --resume.
Guard the flag behind `!resumeSessionId` so it is only appended on
fresh session starts.
