## Thinking Path > - Paperclip manages agents and saves their work when execution stops. > - The Daytona plugin saves an archive through a terminal when disk capacity prevents the normal archive or download copy. > - That fallback sent one 40 KiB chunk and waited for its host write acknowledgement. > - Network delay then applied to every small chunk. A large archive could exceed the recovery deadline even while bytes were moving safely. > - This pull request sends a bounded window of chunks and still acknowledges every completed host write. > - The benefit is faster recovery over delayed connections, with bounded memory and the existing size, space and completion checks. ## Linked Issues or Issue Description Refs #19034, which added the capacity fallback. **What happened?** The archive fallback waits for one network round trip after each 40 KiB chunk. A saved workspace archive can be much larger than that chunk. Repeating a timed-out transfer does not remove this throughput limit. **Expected behavior** Allow a small amount of data to travel before waiting for acknowledgements. Keep memory bounded, write bytes in order, and stop after any write or protocol failure. **Steps to reproduce** 1. Run the real Bash archive sender against a host that delays each acknowledgement by 400 ms. 2. Transfer 1 MiB plus a partial final chunk with a four-second deadline. 3. The original implementation times out. The bounded-window implementation completes and preserves the exact source bytes. **Paperclip version or commit** The failing regression uses the original implementation from `6a66c09f7f7`. ## What Changed - Send at most sixteen 40 KiB chunks before collecting their acknowledgements. Drain the final partial window before the completion receipt. - Serialize host writes and reject more than sixteen pending frames. Stop queued writes on the first failure. - Keep per-frame size checks, total archive limits, the 1 GiB host space reserve, the transfer deadline and bounded teardown. - Add a real Bash regression with delayed acknowledgements, plus overflow and failed-write coverage. Update the plugin documentation. - Update the agent-creator test fixture for the required directory membership role introduced by #15183, which otherwise breaks merged CI typechecking. ## Verification - Failing first: the final real-Bash regression fails against the original source with `Daytona archive stream timed out`. It passes with the change. The empty-stream case passes too. - Standalone Daytona package `pnpm test`: 578 passed, 8 skipped. The skips are the existing opt-in live tests. - Standalone package `pnpm typecheck` and `pnpm build`: passed. - `pnpm test src/file-sync-capacity.live.test.ts` with a staging Daytona key: 2 passed on isolated test sandboxes. This covers actual terminal transport, stop/start, archive and file-copy capacity failures, exact saved hashes, safe links, cleanup and a second export. The tests removed their own sandboxes. - The production dependency assumption is bounded: at most 640 KiB of decoded payloads can wait for host writes. The parser also has a bounded encoded buffer. No background work or idle timer is added. - Initial hosted CI failed with TS2741 in `ui/src/lib/agent-creator.test.ts` after #15183 made `membershipRole` required. Rebased onto that change and added the nullable field to the fixture. UI `pnpm typecheck`, all 4 existing creator-label tests, and `pnpm check:token-gates` now pass locally. Hosted CI subsequently passed on the updated head. - `git diff --check` and a local secret and PII scan: passed. - Full repository checks were not repeated locally for this standalone plugin change. Hosted verification at `bf6b3cb6a622a9523c72b86fdfe616555c8f3ef8`: all 53 check runs passed, with the 2 opt-in Storybook checks skipped; both required gates (`ci / verify`, `ci / e2e`) passed. Greptile is 5/5 at this exact head, with no review threads or merge conflicts. The separate non-required `security/snyk (cryppadotta)` status remains pending; it is not claimed as passed. ## Risks - A burst can queue up to sixteen chunks instead of one. The receiver enforces this bound and acknowledges a chunk only after its ordered host write. - The timeout budget is unchanged. A connection that cannot finish within that budget can still fail. This change does not retry a provider turn or change file-recovery authority. - Source confinement, archive validation, successful producer completion and publication rules are unchanged. No schema migration. ## Model Used - OpenAI `gpt-6.1-sol` with xhigh reasoning, in Codex through T3 Code. Tool use included source edits, real Bash and filesystem tests, and isolated Daytona tests. The runtime does not expose its context window. ## 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 `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) 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>

Editor dependency identity
Keep the root and workspace overrides for @codemirror/state,

extension identity, while Lezer parsers and syntax highlighters require shared
NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with

installed dependency graph and highlights sample code through the editor's real
language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
