DottaandClaude Opus 5.5 9f0ebf6f70 fix(accounting): close a run whose turn was lost on restore, and stop succeeded runs holding all work (#19724)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Budgets hold new work while the cost of completed runs is unknown
> - In a restart chaos wave, a native ACPX Claude run crossed a server
kill, resumed, and succeeded. Its usage receipt never became complete.
> - For the 10-minute closure bound, admission refused all work in the
company. This included tasks that never crossed a fault.
> - This pull request fixes the receipt for a turn that was lost on
restore. It also stops a succeeded run from holding all new work.
> - The benefit: one late usage report no longer freezes a company, and
hard stops still apply.

## Linked Issues or Issue Description

Refs #19700 (the accounting closure bound that this follows).

**What happened?**
A native ACPX Claude run crossed a server SIGKILL in the middle of a
turn. The Runner restored the session, and the run succeeded 54 seconds
after it started. All 17 usage receipts stayed incomplete. Accounting
settled the run only at the 10-minute closure bound. During those 10
minutes, admission refused all company work with "Company cannot start
work while completed runs await accounting".

**Root cause**
ACPX reports provisional usage (`runDeltaComplete: false`) until a turn
ends. The kill lost the turn that was active, so that turn never got a
complete report. The restored Runner failed that turn with
`provider_turn_lost_on_restore`. Native turn accounting
(`createNativeTurnAccounting`) required every terminal turn to have
usage, so this turn kept every later receipt incomplete. This was true
even after the continuation turn completed with full usage. The
admission gate then counted the succeeded run as a pending terminal run
for the whole company.

**Expected behavior**
The receipt closes when the run's turns end. A turn that was lost on
restore makes the usage a lower bound. A succeeded run with only usage
outstanding does not hold other work.

## What Changed

- `native-usage-accounting.ts`: a turn that failed with
`provider_turn_lost_on_restore` and has no complete usage no longer
holds the receipt open. The snapshot marks `accountingUsageLost`.
- `native-session-executor.ts` and `native-usage-delivery.ts`: such a
receipt carries the provenance note "a provider turn was lost on restore
and never reported its usage; observed usage is a lower bound".
- `anthropic-pricing.ts` and `codex-pricing.ts`: the rate-card pricers
keep a producer's provenance note.
- `native-usage-delivery.ts` and `usage-receipts.ts`: remote producer
delivery keeps a `lostOnRestore` marker on the receipt's producer event,
so replay also excuses the lost turn. Receipts saved without the marker
still replay.
- `budget-exposure.ts` and `budgets.ts`: admission waits only for
pending runs that ended without succeeding (`waitingRunCount`). A
succeeded run whose provider reported observed usage is bounded like a
running run: its observed cost counts toward spend and reservation
capacity, and its settled charge can still reach the hard stop.
- `budget-exposure.ts`: a closure that timed out because of a
control-plane restart keeps the unpriced-usage exemptions, whatever its
token count. Restart evidence is a replaced receipt source, a native
recovery transition that is not an ordinary same-run retry, or a turn
lost on restore. A second chaos run showed the need. It recovered and
succeeded, but its final usage report was lost with the restart, so it
settled as unpriced 0 cents. The blocking policy then opened a hard
incident and paused the company. A timed-out closure with no restart
evidence still counts.
- `run-cost-accounting.ts`: a lost receipt that carries a positive
provider-reported cost settles at that cost as an estimate marked as a
lower bound, not as unpriced.
- `paperclip-runner-tool-authority.ts` and `budgets.ts`: a running run's
own tool mutations are evaluated as admitted work. Hard stops and pauses
still refuse them. Accounting holds, recovering runs and budget inputs
that await evaluation do not. In a third chaos run, a live run's write
to its task document was refused during a temporary hold, so the run
proposed a blocked result.
- `doc/SPEC-implementation.md`: documents these rules.

Policy choice: a succeeded run's provider work is over, so it has less
unknown spend than a running run. Running runs never held admission.
Failed, cancelled, timed-out and interrupted runs still hold new work,
because their provider may not have stopped. A per-agent gate would
still freeze unrelated work of the same agent. A per-reservation gate
does not help when `reservationCents` is 0, which was the case in this
wave.

## Verification

- Live: a restart chaos wave ran master plus this PR (c2a48fb1e0) with
no masking. It passed 6/6, and every task crossed a restart. There were
0 accounting holds, 0 refused agent writes, 0 company pauses, and every
cost settled as estimated.

- Red then green: `native-usage-accounting.test.ts`, "closes a run whose
earlier turn was lost on restore, as a lower bound". It uses the event
sequence of the chaos run.
- Red then green: `closed-native-receipt-accounting.test.ts`, "does not
hold other work for a succeeded run with only usage outstanding". It
also checks that the hard stop still applies.
- I changed "neither pauses nor holds admission while a succeeded run's
charge commits" to the new policy. A failed run in the same state still
holds new work.
- Red then green: `closed-native-receipt-accounting.test.ts`, "never
hard-stops a blocking policy for a restart-derived timed-out receipt".
It uses the zero-token row shape of the chaos run and a case with
unpriced tokens. Without the fix, the company was paused.
- Red then green: `runner-api.integration.test.ts`, "lets a running run
write during a temporary accounting hold, but not after a hard stop".
- Red then green: `closed-native-receipt-accounting.test.ts`, "does not
hold other work for the s7504 succeeded row shape".
- Red then green: `closed-native-receipt-accounting.test.ts`, "settles a
timed-out restart receipt at its provider-reported cost, without holding
or pausing". It uses the OpenCode/OpenRouter row shape from a fourth
chaos run.
- `anthropic-pricing.test.ts`: the rate-card provenance keeps the
lower-bound note.
- Local: `closed-native-receipt-accounting`, the budget suites,
`native-usage-accounting`, `native-usage-delivery.integration`,
`native-runner-restart-recovery.integration` and `anthropic-pricing` all
pass (187 tests). Server `tsc --noEmit` is clean. `pnpm verify` asks for
CI coverage because the spec changed.

## Risks

- A succeeded run whose final charge is higher than its observed cost
can let one more task start before the charge commits. The hard stop
then pauses the scope as it does for a running run that overruns.
- A run that includes a lost turn settles with a lower-bound usage
figure. The provenance says so, and a later receipt still reconciles
through the late-receipt path.

## Model Used

- Anthropic Claude Opus 5.5 (`claude-opus-5-5`), Claude Code agent with
tool use and code execution.
