## Thinking Path > - Paperclip manages AI agents and their work. > - Remote runs need a snapshot of the task workspace before the agent starts. > - The snapshot lists untracked filenames through the shared Git scan scheduler. > - A generated directory with a few thousand long filenames can exceed the 1 MiB output limit. > - This stops setup and prevents the agent from continuing its task. > - This change gives that listing a 32 MiB bound and keeps the explicit file snapshot. > - Normal generated trees can now pass setup, while larger snapshots still fail at a finite limit. ## Linked Issues or Issue Description Refs #11572 and #12214 for the existing bounded scan and ignore-scan protections. **What happened?** An agent continuation failed during workspace setup with `Workspace Git scan exceeded its output limit`. A real Git fixture reproduces the untracked-file path: 5,000 long filenames in one generated directory exceed its 1 MiB output limit. **Expected behavior** The workspace snapshot must support ordinary generated trees with thousands of files. It must keep a finite output bound and select explicit files before staging. **Steps to reproduce** 1. Commit a base file in a Git repository. 2. Add 5,000 untracked files with long names in one new directory. 3. Call `readGitWorkspaceSnapshot` with the normal scan limits. 4. Observe the output-limit error before this change. **Paperclip version or commit** Base commit: `640dee1`. **Deployment mode** Remote sandbox execution from source. ## What Changed - Increase the untracked-file snapshot output bound from 1 MiB to 32 MiB. - Keep explicit file selection, the shared scheduler, the timeout, and the other scan bounds. - Test that 40,000 long filenames above the old 8 MiB bound reach the snapshot. Reuse those files with deeper paths to prove that output above 32 MiB still fails. - Test that files created after the snapshot, including an ignored secret, stay out of the overlay archive. - Check the workspace root identity and reject selected paths with symlinked parent directories before upload. - Test root replacement after path resolution, including root-level selected files. - Preserve existing workspace root aliases by capturing the resolved root before snapshot selection. Test that later alias retargeting cannot change the archive contents. - Stop staging on permission and I/O errors; continue to allow missing files. - Test these failures and preserve selected symlink entries. - Accept valid case-renamed directories by checking ancestor file types. A modeled case-insensitive regression failed before this correction and now passes. - Give the 40,000-file fixture enough time to remove its files. - Document the larger bound and staging behavior. ## Verification - Red: the 5,000-file regression failed with `stdout maxBuffer length exceeded` before the fix. - A separate check through the real server scheduler reproduced `workspace_git_scan_output_limit` on the original code. The revised code selected all 5,000 files. - The late-file regression failed against the first PR revision because the archive contained `drafts/late.secret`. It passes with the final explicit-file approach. - The staging regressions failed before the review fix: a substituted parent directory and permission/I/O errors were accepted. All three cases now stop before upload. - Green: 134 tests passed across `git-workspace-sync.test.ts` and `sandbox-managed-runtime.test.ts` with Vitest 4.1.11. This includes complete selection above 8 MiB and rejection above 32 MiB. - `pnpm --filter @paperclipai/adapter-utils... typecheck` passed after the revision. - The module-boundary check and `git diff --check` passed. - `pnpm -r typecheck` and `pnpm build` stopped in the Rust runner steps because this environment has no `cargo` executable. - The full `pnpm test:run` attempt ended with `SIGKILL` during the general server suite. It did not finish. That full-suite result belongs to the earlier revision. Fresh checks are required for this revision. - The new regression fails at the old 8 MiB bound with `stdout maxBuffer length exceeded`. All 134 focused tests pass with the 32 MiB change. - The affected typechecks and module-boundary check pass. The full local typecheck requires Cargo, which is absent in this environment. - Final verification for `b43e9bc95e55382c6a9bfe200487c164770c8be8`: 54 successful checks/statuses and two skipped Storybook checks. No checks remain pending or failed. - The [CI run](https://github.com/paperclipai/paperclip/actions/runs/36315569674) passes on attempt 2. The first attempt had one unrelated preview-fixture readiness timeout. That exact test passed locally; its CI shard passed on the single rerun. - [Greptile reports 5/5](https://github.com/paperclipai/paperclip/pull/14194#issuecomment-5852045501) on this revision. All review threads are resolved. - [Security review accepts the documented memory tradeoff](https://github.com/paperclipai/paperclip/pull/14194#discussion_r4115149465) for this finite mitigation. The separate streaming follow-up will remove full-list buffering. - This revision also passes affected local typechecks and the module-boundary check. Full local typecheck/build stop because Cargo is absent. The full local Vitest attempt was stopped after about 18 minutes once all remote gates passed; it did not complete locally. ## Risks - Each untracked-file scan can buffer up to 32 MiB instead of 1 MiB. The scheduler still limits concurrent scans and execution time. - Snapshots above 32 MiB still fail with the existing error. Tracked and ignored-file scan bounds stay unchanged. - A workspace that replaces a selected path’s parent with a symlink now fails staging. - Detailed logs from the reported host were unavailable. The exact command that exceeded its limit on that host is unconfirmed. ## Model Used OpenAI GPT-6 through Codex, with reasoning, tool use, and code execution. The runtime does not expose a more specific model build or context window size. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub references) - [x] My branch name describes the change and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
