## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip records agent run outcomes through telemetry and run
lifecycle services
> - Terminal run transitions need one consistent event for outcome
analysis
> - The current paths do not report every terminal transition through
one event
> - This pull request adds the agent.task_run event and emits it at each
terminal transition
> - The benefit is complete run outcome data without exposing raw task
identifiers
## Linked Issues or Issue Description
**What existing behavior does this improve?**
Paperclip telemetry reports agent activity, but it does not report every
terminal task run through one event.
**Subsystem affected**
Cross-cutting (multiple of the above): packages/shared telemetry and
server run lifecycle services.
**Current behavior**
Several run paths write a terminal status without a matching
agent.task_run telemetry event.
**Proposed behavior**
Each terminal run transition emits one agent.task_run event. The event
records the terminal state and uses the existing pseudonym helper for
the optional task identifier.
**Reason and benefit**
Complete terminal-run data helps operators measure agent outcomes. The
pseudonym helper prevents the raw task identifier from leaving the
installation.
**Breaking changes**
None. The change adds an event and keeps existing event behavior
compatible.
## What Changed
- Add the agent.task_run telemetry contract and client helper.
- Reuse the existing pseudonym helper for the task identifier. The
helper hashes the identifier with a per-installation salt and returns 16
hexadecimal characters. The raw identifier never leaves the
installation. Existing identifiers do not move.
- Emit one event from each legacy, native, recovery, and issue terminal
transition.
- Keep emissions outside database transactions and make delivery
best-effort.
- Add regression tests for event shape, hashing, terminal transitions,
and emission failures.
- Document the event and its privacy rule in the telemetry data
contract.
## Verification
- `npx tsc --noEmit` in `server/` passes at the submitted commit.
- The pull-request CI suite must pass. CI is the authority because local
Vitest has a known dependency artifact.
- The added regression tests cover event output shape, per-installation
hash divergence, raw identifier handoff, omitted identifiers, and
non-throwing emits.
## Risks
- A missed terminal path could reduce event coverage.
- Telemetry delivery remains best-effort and cannot change run
finalization.
- The pseudonym helper uses installation-specific state, so identifiers
differ between installations.
## Model Used
OpenAI Codex, GPT-5, tool use and code execution. Context window details
were not provided.
