## Thinking Path

- Issue #16034 reports a defect in paperclipai/paperclip.
- Root cause, as the fixing agent read it: emitAcpxFailure in
packages/adapter-utils/src/acpx-engine/execute.ts built the run error,
summary, and acpx.error message from Error.message alone. It ignored the
JSON-RPC error's 'data' explanation and numeric 'code', so every ACP
phase failure (create runtime, ensure session, configure session, turn)
showed only 'Internal error'.
- This pull request: Preserve sanitized ACP JSON-RPC error details and
numeric codes in run errors, summaries, and acpx.error records

## What Changed

- `packages/adapter-utils/src/acpx-engine/execute.ts`: This change is
kept from the earlier attempt. The shared failure handler reads the
explanation from a string 'data', 'data.details', or 'data.message'. It
appends that text to the message unless the message already contains it,
and runs the result through sanitizeTerminalSessionFailure. A numeric
JSON-RPC code is recorded as errorMeta.rpcCode. Errors without these
fields keep their old message.
- `packages/adapter-utils/src/acpx-engine/execute.test.ts`: The existing
harness keeps the earlier it.each case, which covers all four phases,
all three detail shapes, redaction, and rpcCode in the acpx.error
record. A new case in the same harness covers the checks that only the
separate file had: detail text already in the message is not repeated,
and a plain Error stays unchanged with no rpcCode.
- `doc/run-log-events.md`: Documents the change to the acpx.error
record: which detail formats are read and in what order, the rule
against repeating detail text, the redaction and 4,096-character title
limit applied through the existing sanitizer, and the optional integer
'rpcCode' field.

## Verification

- Reproducing test(s), added in this PR:
`packages/adapter-utils/src/acpx-engine/execute.test.ts`
- They fail on the base commit and pass with the fix, each twice in a
fresh sandbox.
- The repository's compile command passes with the fix applied.
- 9 existing test file(s) near the change passed.
- The full test suite passes except for the 11 file(s) that already fail
on the base commit.

## Risks

- Written by an automated pipeline, not a person: review it as you would
an outside contribution.
- Risk tier of the touched paths: 2.
- The scope reviewer found it also changes, beyond the report: Plain
Error, non-object throw, string or Node errors with string codes
(ENOENT), and data that is empty, missing, non-string or malformed
- The scope reviewer found it also changes, beyond the report:
messageOverride callers (turn timeout, handshake guard)
- It crosses a trust boundary. Check each crossing against what the
issue asked for, and against who asked:
- data-exposure
(packages/adapter-utils/src/acpx-engine/execute.ts:3626): Text the ACP
child process controls (JSON-RPC error 'data', 'data.details' or
'data.message') is now added to the run error message and summary that
users see; it passes through sanitizeTerminalSessionFailure redaction
first.
- logging (packages/adapter-utils/src/acpx-engine/execute.ts:3651): The
'acpx.error' run-log record now carries the provider's explanation in
'message' and a new integer 'rpcCode' field, both supplied by the child,
on every failure route that calls emitAcpxFailure without a
messageOverride, including the handshake-guard route that suppresses
stderr.
- data-exposure
(packages/adapter-utils/src/acpx-engine/execute.ts:3639): The numeric
JSON-RPC error code from the child is now copied into
'classified.errorMeta.rpcCode', which reaches the adapter result's
errorMeta and the places that store or show it.
