DottaandPaperclip cccde7122b Trace execution preparation and durable response persistence (#16419)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The server prepares an execution environment before it starts an
agent.
> - Operators need to distinguish preparation, provider wait, and
response persistence.
> - Existing preparation phases start separate traces, and the native
session trace ends before the final response is saved.
> - This pull request adds an execution-attempt trace and detailed spans
at the existing work boundaries.
> - The benefit is a measurable startup and settlement path without
changing execution policy.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Operator-configured OpenTelemetry tracing for agent preparation,
startup, and durable response storage.

**Subsystem affected**

Server orchestration, native Runner startup, and the Honeycomb run link.

**Current behavior**

Preparation phases start independent roots. Workspace lock waits,
authorization groups, runtime asset work, provider-pack fallback, and
the gap after provider completion are hard to attribute.

**Proposed behavior**

Use a server-owned async context for each execution attempt. Parent
nested work to that attempt. Link the separately sampled native session
because its ingress and queue history can begin earlier. Record
transaction entry, lock waits, grouped authorization, asset preparation,
artifact fallback, copyback, and response commit.

**Reason and benefit**

Operators can identify expensive work from recorded boundaries instead
of inferring the cause from elapsed time. Nested and concurrent
durations remain visible and must not be added together.

**Breaking changes**

No API or execution-policy change. New Observability span names and
closed count attributes are documented. The existing local
run-performance schema also records the additional provider-pack and
harness measurements.

Refs: #16178, #16205, #16330.

## What Changed

- Add `task.execution_attempt` with same-run async ownership,
independent root sampling, and native-session links.
- Measure workspace transaction entry and settlement, advisory and row
waits, source scans, reader groups, notifications, and writes.
- Measure runtime selection and each concurrent instructions, skills,
and MCP branch. Separate manifest, cache, materialization, and
verification work.
- Measure provider-pack discovery, verified reuse or upload, final
verification, and remote harness state checks.
- Measure workspace settlement, accounting, liveness, response
authorization, comment commit, and publication enqueue.
- Preserve the silent endpoint-off path, including when another library
has registered a tracer. Bound repeated detail spans to 16 per name per
attempt.
- Extend the Honeycomb run link and document the actual coverage and
remaining gaps.

## Verification

- After resolving the conflict with retained-reader batching on
`b98cdaea531c8447637cd4dcc19c61b3f5f41844`, all 61 targeted query,
authorization, workspace-preparation and trace-boundary tests passed.
The server typecheck passed. Reader tests still bound query count, avoid
loading retained run payloads and enforce fresh project grants on every
publication attempt.
- Before that base integration, the tracing/exporter group passed 855
tests with 2 optional-SDK skips across 10 files and no inherited OTLP
endpoint. It covers real PostgreSQL waits/rollback, durable response
commit, assembled heartbeat preparation, concurrent parentage, sampling
and tracer failure isolation. Native workspace/history tests passed 23
cases. These results remain supporting evidence for the unchanged
tracing paths.
- Full workspace typecheck and build passed during implementation. Full
sharded CI, release validation, E2E and Apex 5/5 passed on prior head
`8cebad80f3856dbcff6f3a6d5d34880ff77a20f2`. Fresh CI, security and Apex
review are required on the current head before merge.
- `pnpm check:token-gates` passed. No styles changed.
- Earlier CI runs exposed exact-source-expression assertions changed by
wrappers, missing run hashes on transaction-boundary spans, and sampling
fixtures without an enabled endpoint. The fixes preserve the calls, add
the declared hash and span cap, and enable tracing explicitly in the
sampling fixtures. Focused repairs passed; the full prior-head CI passed
after those repairs. Earlier failed run:
https://github.com/paperclipai/paperclip/actions/runs/38729131366.
- The full local `pnpm test:run` was stopped after the base advanced
during that process. Its mixed-version results are not final-head
evidence. A full local-suite pass is not claimed.
- The old-head Superagent scan stalled at 35%. The current head has a
fresh scan; no security pass is inferred from the old pending result.
- No deployed Honeycomb acceptance is claimed by this code change.

## Risks

- Enabled tracing creates more spans. Repeated detail spans are bounded,
and inventories use group spans.
- The attempt and native session remain linked traces. Historical queue
time can precede the attempt, and nested intervals overlap.
- A committed comment proves durable server storage. Publication enqueue
and realtime dispatch do not prove external delivery or browser paint.
- New custom attributes use only the existing run hash and validated
file/byte counts. No SQL, paths, permissions, content, or exception text
is added.

## Model Used

OpenAI GPT-6 through Codex. The serving model ID and context window size
are not exposed in this session. The agent used reasoning, tools, code
editing, and code execution.
