## Thinking Path
> - Paperclip is the control plane for autonomous agent companies, so
non-terminal issue state must always have a clear live, waiting, or
recovery owner.
> - This change stays inside the server reliability and liveness
subsystem for assigned issue recovery, blocker attention, and live-run
polling.
> - Closed PR #4860 mixed this reliability work with separate
mutation-boundary policy changes, which made review and merge risk too
broad.
> - [PAP-2981](/PAP/issues/PAP-2981) asked for a replacement PR
containing only the remaining reliability slice and explicitly excluding
user-assignment and execution-policy restrictions.
> - Follow-up review also split `advanced` run-liveness continuation
behavior out of this PR so it can be reviewed separately.
> - The implementation hardens repeated recovery escalation, expands
blocker-attention coverage for explicit waiting and recovery paths, and
caps company live-run polling defaults.
> - The benefit is a smaller reliability PR that improves liveness
behavior without changing agent/user mutation authorization boundaries
or `advanced` continuation semantics.
## What Changed
- Avoid repeated liveness escalation updates when the source issue is
already blocked by the same open escalation.
- Treat open liveness escalation recovery issues, their source issues,
and their leaf blockers as covered waiting paths in blocker attention.
- Cap default company live-run polling at 50 rows for both `minCount`
and `limit`, including explicit zero values, to avoid unbounded
responses.
- Preserve the existing behavior where succeeded `advanced` runs are
considered productive/healthy for stranded-work recovery and are not
actionable bounded run-liveness continuations.
- Added focused server coverage for recovery dedupe, blocker attention,
liveness escalation, run continuations, and live-run polling.
## Verification
- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run
server/src/__tests__/heartbeat-process-recovery.test.ts
server/src/__tests__/heartbeat-issue-liveness-escalation.test.ts
server/src/__tests__/issue-blocker-attention.test.ts
server/src/__tests__/run-continuations.test.ts
server/src/__tests__/agent-live-run-routes.test.ts`
- Result: 5 files passed, 63 tests passed.
- `pnpm --filter @paperclipai/server typecheck`
- Result: passed.
- No UI changes; screenshots are not applicable.
## Risks
- Recovery and blocker-attention classification changes can affect which
blocked chains are shown as covered versus needing attention.
- Live-run polling now treats omitted, invalid, or non-positive `limit`
/ `minCount` values as the capped default of 50.
- `advanced` run-liveness continuation behavior is intentionally
excluded from this PR and split for separate review.

with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
- OpenAI Codex, GPT-5, code execution and GitHub CLI tool use, medium
reasoning effort.
