## Thinking Path
> - Paperclip is the control plane for autonomous AI companies.
> - Company export/import lets operators move company state, including
issue threads and agent execution context, between Paperclip instances.
> - Issue comments can be enriched by nearby heartbeat run logs so
exported threads preserve useful agent/run attribution metadata.
> - Some local instances can have heartbeat run database rows whose
local log files were deleted or never copied into the current workspace.
> - The export path should still include the original user comments
instead of failing because optional run-log metadata is unavailable.
> - This pull request makes comment run-log metadata derivation tolerate
missing local log files, logs the missing-file condition for operators,
and adds a regression test.
> - The benefit is safer company exports for real instances with
incomplete local run-log storage.
## What Changed
- Treat missing local heartbeat run logs as absent optional metadata
while listing issue comments.
- Emit a structured warning with `runId` and `logRef` when optional
comment-attribution log content is missing.
- Preserve the existing error behavior for non-404 run-log read
failures.
- Added a regression test proving user comments still list when a
candidate attribution run has a missing local log reference.
## Verification
- `pnpm exec vitest run server/src/__tests__/issues-service.test.ts -t
"candidate attribution run log is missing"` passed: 1 selected test
passed, 47 skipped.
- `pnpm --filter @paperclipai/server typecheck` passed.
- Greptile Review passed with Confidence Score 5/5 and zero unresolved
threads on commit `f68cac02bf98d7d31e7831e5bdfa95cffa85e254`.
- GitHub PR workflow run succeeded: `policy`, `verify`, four serialized
server suites, `e2e`, and `Canary Dry Run` all passed.
- `security/snyk (cryppadotta)` passed.
- Confirmed this branch is on top of `public-gh/master` and
`pnpm-lock.yaml` is not in the PR diff.
## Risks
- Low risk. The change only softens optional comment metadata derivation
for 404/missing local log files; other log read errors still throw.
- Exported comments in this edge case may lack derived run metadata, but
they remain visible/exportable instead of failing the request.
- Operators may see new warnings when historical run-log references
point to missing local files; those warnings indicate degraded optional
metadata, not data loss.
## Model Used
- OpenAI Codex, GPT-5 coding agent in this Paperclip heartbeat, with
shell/git/GitHub CLI tool use.
