DottaandClaude 1e13c58a4e fix(heartbeat): name the cause of generic adapter failures and keep SQL text off the board (#20483)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Heartbeat run settlement records why a run failed, and the board
shows that record.
> - Runs that fail without a named code settle as `adapter_failed` (or
`setup_failed`) with no cause.
> - A user, an operator, and the restart chaos harness cannot tell what
went wrong from such a run.
> - Some run errors also show raw SQL statement text to users.
> - This pull request records a bounded `failureCause` code for generic
failures, shows it on the board, and keeps SQL text out of run errors.
> - The benefit is that a generic failure now names its cause, for
example "adapter failed (40001)", without leaking messages, SQL, or
secrets.

## Linked Issues or Issue Description

Refs #20385 (the nested-cause extraction this change reuses). Related:
#20421 (restart chaos universal checks U1-U4).

**What happened?**

The restart chaos audit of 79 saved waves found 30 failed runs with
`errorCode: "adapter_failed"` and a null or generic error. Every U3
("diagnosable") warning was `adapter_failed`. Nobody could tell what
failed. Some board run errors also showed raw SQL statement text from
wrapped database errors (Drizzle `Failed query: ... params: ...`).

**Expected behavior**

A run that fails with a generic code names a short, safe cause. The
board shows the cause next to the stop reason. Run error text never
shows SQL statements or their parameters.

**Steps to reproduce**

Make an adapter throw a wrapped database error (an `Error` whose nested
`cause` has `code: "40001"` and whose message has a Drizzle `Failed
query:` statement). Before this change, the run settles as
`adapter_failed` with no cause, and `heartbeat_runs.error` contains the
SQL statement and parameters. The new tests in
`server/src/services/heartbeat/run-completion.test.ts` reproduce this.

## What Changed

- Runner: move the #20385 event-commit cause extraction into
`safeErrorCauseCode`
(`packages/paperclip-runner/src/control-plane/safe-error-cause.ts`) and
export it. The Runner's own diagnostics use the same function, unchanged
in behavior.
- Shared: add the `failureCause` contract
(`packages/shared/src/run-failure-cause.ts`): one `[A-Za-z0-9_.:-]`
token of at most 80 characters, `normalizeRunFailureCause`,
`readRunFailureCause`, and `withoutSqlStatementText`.
- Server: add `server/src/services/heartbeat/run-failure-cause.ts`.
Settlement records `resultJson.failureCause` only when the code is
generic (`adapter_failed`, `setup_failed`). `errorCode` stays the same.
- Thrown errors (`failRun`, `failRunSetup`): `provider_http_<status>`,
else `provider_<category>`, else the first safe code in the error and up
to three nested causes (`40001`, `ECONNRESET`), else the error class
name, else `unknown_error`.
- Adapter results without a code (`completeRun`): the error family,
`signal_<name>`, `process_cancellation_failed`, `exit_code_<n>`,
`adapter_reported_error`, or `unknown_error`.
- The failure log lines (`heartbeat execution failed`, `heartbeat
execution setup failed`, and a new `heartbeat run failed` warning for
generic adapter results) include `failureCause` and `errorCode`.
- Server: replace SQL statement text in run error text with "Database
query failed (<cause>)" at all three settlement paths, including the
cancelled branch. The execution blocker's `runError`, the attention
inbox (failed-run excerpt and metadata), and continuation summaries
apply the same replacement on read, so older rows also stop showing SQL
there.
- Server: Retry admission and failed-preparation replay accept only a
closed set of `resultJson` keys. `failureCause` is added to each of
those lists (`task-retry.ts`, `chat-channels/failed-run-retry.ts`,
`cancelled-native-startup.ts`, `fresh-workspace-continuation.ts`). It is
a diagnostic code with no execution or replay authority, so a
failed-preparation run stays retryable.
- Server: `runsForIssue` returns a validated top-level `failureCause`.
It is null for older rows, non-string JSON values, and malformed values.
- UI: `RunForIssue.failureCause`; `IssueRunLedger` shows "adapter failed
(40001)". Older runs keep "adapter failed". The Storybook run-ledger
fixture has a failed run with a cause.
- Restart chaos harness: run samples keep `failureCause`. U3 treats a
generic code with a specific `failureCause` as diagnosable. A bare
`Error`, `unknown_error`, or the no-code fallback
`adapter_reported_error` still counts as vague. U3 stays a warning.
- Docs: `doc/run-log-events.md` and the harness README describe the
field and the SQL replacement.

## Verification

- Red before the fix: the four new `run-completion.test.ts` cases failed
against `origin/master`'s `run-completion.ts` (no `failureCause`, SQL
text in `error`).
- Green:
- `server/src/services/heartbeat/run-completion.test.ts`: all tests
passed (real embedded PostgreSQL). New cases cover a nested `40001`
three levels deep for execution and setup failures, SQL and a secret
parameter absent from `error` and `resultJson`, the bound (an
81-character code and a SQL "code" fall back to the class name),
`exit_code_137` for a code-less adapter result, a cancelled result with
SQL text, no cause for a named code, and the log line. On this loaded
host the suite's `afterAll` database teardown hit its 30 s hook limit
after every test passed (the known local teardown limit, also seen in
#20385). CI runs the suite.
- `server/src/services/heartbeat/run-failure-cause.test.ts` (4),
`server/src/__tests__/activity-service.test.ts` (recorded, legacy,
malformed, overlong, boolean, and number cause projections),
`server/src/__tests__/issue-continuation-summary.test.ts` (legacy SQL
row).
- `packages/shared/src/run-failure-cause.test.ts` (6),
`ui/src/components/IssueRunLedger.test.tsx` (21), restart chaos
`universal.test.ts` and `observer.test.ts`.
-
`packages/paperclip-runner/src/control-plane/durable-prp-control-plane.test.ts`:
207 passed (the stall-diagnostic cases still read `40001` and
`ECONNRESET`).
- Typecheck: shared, runner, server (all layers), UI, restart chaos
harness. `pnpm check:token-gates`: all gates clean.
- `pnpm verify` returned exit 2 (global doc input changed); required CI
supplies broad coverage.
- CI on `6295f8d` found that the new key made failed-preparation runs
ineligible for Retry (`chat-channels.integration.test.ts` saved
board-message Retry got 409;
`workspace-recovery-preparation-dispatch.test.ts` dispatched 0 Retries).
Both reproduced locally and pass after the allowlist fix, with the other
459 Retry cases in `chat-channels.integration.test.ts` and all 25 in
`workspace-recovery-preparation-dispatch.test.ts`.
- No chaos waves were run. Storybook was not opened in a browser; the
fixture typechecks and the label is covered by the UI test.

## Risks

- Low risk. `errorCode` values do not change, so retry, recovery, and
comparison logic is unaffected.
- No schema change and no migration. `failureCause` is a new optional
`resultJson` key. Rows saved by the previous release have no key and
render as before; a new row read by an old server is ignored.
- The SQL replacement only acts on a Drizzle `Failed query:` marker, or
on `$n` placeholder text with a statement shape. Ordinary error text
does not change. When it acts, it also drops the text after the
statement.
- Code that checks `resultJson` against a closed key list must allow
`failureCause`. I found and updated the four lists on the Retry path; a
list I missed would refuse a Retry for a run with a generic failure.
- This is the run log / instance database path. It adds no Telemetry
event.
- The server failure log line still logs the raw error message
(unchanged behavior); only the board-facing text is changed.
