DottaandClaude 289b402c26 fix(runner): settle a saved governed wait whose parked turn was lost on restore (#20519)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native agent run can ask the board a question and park on that
saved (governed) wait
> - PR #20494 made a saved wait settle after a control-plane restart for
Codex, which reports the parked turn as interrupted
> - Claude runs through ACPX. After a kill -9 restart, Runnerd restores
the conversation and reports the parked turn as `turn.failed` with
`provider_turn_lost_on_restore`
> - The governed-wait drain and the saved-replay check rejected every
failed terminal as unproven, so the saved question failed and the task
needed a human Retry
> - Runnerd emits `provider_turn_lost_on_restore` only after it proves
that the old provider lifetime ended. That is the same proof as an
interrupted terminal
> - This pull request accepts that recoverable restart loss as proof for
a saved governed wait, and only that failure
> - The benefit is that a Claude question survives a control-plane kill
the same way a Codex question does

## Linked Issues or Issue Description

Refs #20494. Related: #20498 (Claude lost cancel reply; this change does
not touch that code).

**What happened?**
Restart chaos wave w-20261110T094930-s214 (Claude, Q1, PV1 and PV2 with
`--provider-fault-restart K1`) failed 2 of 2 Q1 tasks with
`R3:retry_needed`. The asking run ended `failed` with
`native_provider_terminal_failed`. Its events show the question saved,
the K1, recovery with `native_governed_wait_settlement_pending`, and
then `turn.failed` with `provider_turn_lost_on_restore` for the parked
turn. The thrown `providerCode` was
`governed_wait_provider_terminal_unproven`.

**What did you expect?**
The saved question settles after the restart. The asking run ends
`succeeded`. The board answer wakes the agent without a Retry.

**Steps to reproduce**
Run the harness with `--adapters claude --workloads Q1 --faults PV1,PV2
--provider-fault-restart K1 --provider-fault-delays 3
--provider-fault-restart-after-seconds 1 --concurrency 1 --tasks 4`. The
new unit-test variants `lost-on-restore-after-restart` and
`lost-on-restore-saved` failed with the same `providerCode` before this
change.

## What Changed

- `native-session-runtime.ts`: add `governedWaitTerminalProven(event)`.
A failed terminal proves the stop only when
`isNativeRestartInterruption(error)` is true (code
`provider_turn_lost_on_restore`, `recoverable: true`). Other terminals
keep the old rule (`providerTerminalObserved !== false`).
- The governed-wait accounting drain and the saved-replay check both use
that helper.
- Tests: two new variants of the #20494 test (a lost terminal after the
restart, and a lost terminal already saved before the next recovery).
Two new rejection cases: a non-restart failed terminal and a
non-recoverable restart loss still fail with
`governed_wait_provider_terminal_unproven`.

## Verification

- `pnpm --filter @paperclipai/paperclip-runner exec vitest run
src/native-session-runtime`: 265 tests pass. The two new settle variants
failed before the fix.
- `pnpm --filter @paperclipai/paperclip-runner exec tsc --noEmit -p .`
passes.
- A live restart chaos wave on this branch (Claude Q1, PV1/PV2 + K1) is
linked in a comment below when it finishes.

## Risks

- Low risk. The change accepts one more terminal as proof for a saved
governed wait. That terminal comes only from Runnerd after it proves the
old provider lifetime ended, and the code already trusts it to continue
a restart-lost turn (`nativeRestartInterruptedTurnId`).
- A failed terminal with any other code, or a non-recoverable restart
loss, is still rejected.

## Model Used

- Claude (Anthropic), model ID `claude-opus-5-5`, with tool use and code
execution in Claude Code.
