>despite the caller seeing an error.

>The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
>
>## Issue description
>`handleCreateRun` performs extra database work *after* `Engine.CreateRun` has committed. If `setRunMetadata` or `RunUsage` fails, the handler returns 5xx even though the run already exists, creating ambiguous outcomes and potential duplicate runs on client retry.
>
>## Issue Context
>`Engine.CreateRun` is explicitly transactional and commits before returning. The API handler then does a separate UPDATE and a usage rollup query, both of which can fail independently.
>
>## Fix Focus Areas
>- internal/api/runs.go[63-86]
>- internal/engine/engine.go[159-219]
>
>## Suggested fix direction
>Choose one of these approaches (prefer 1):
>1) **Make creation atomic** by moving name/description/category into the same DB transaction as the run insert (e.g., extend the engine/store insert path to include these columns, or introduce a CreateRun variant that accepts metadata and writes it in the same `InTx`).
>2) **Eliminate post-commit failure points** in the handler:
>   - Avoid querying `RunUsage` on create (a newly-created run has zero attempts; return a zero rollup deterministically without a DB query).
>   - Decide how to handle `setRunMetadata` failures without returning 5xx after commit (e.g., treat as retryable background update, or return success but clearly reflect persisted metadata by re-reading / or omitting it).
>3) If you keep post-commit work, add an idempotency key to POST /runs so client retries cannot create duplicates (larger API change).

>## Issue description
>`workspace.measure()` invokes `git diff` commands in a repo directory. Git can honor repository configuration for diff execution paths (e.g., external diff drivers / textconv), which may result in executing configured commands during the measurement step.
>
>## Issue Context
>The bridge is running subprocesses (`subprocess.run(["git", ...], cwd=repo, ...)`) and uses `git diff --stat` and `git diff --name-only` against `head_before`.

>## Suggested fix direction
>Harden the git invocations used for measurement:
>- For diff-based calls, add flags that disable command-executing diff features:
>  - `git diff --no-ext-diff --no-textconv ...`
>  - optionally also `--no-pager` (or `-c core.pager=cat`) to ensure no pager behavior.
>- Consider using `git -c diff.external= -c diff.trustExitCode=false ...` style overrides to prevent repo config from enabling external tooling.
>- Apply the same hardening consistently anywhere else these adapters run diff commands (claude/codex variants if identical).
