## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agents must publish generated files so users can inspect their results after a sandbox stops. > - Legacy sandbox bridges blocked attachment listing and could not carry multipart binary uploads through the queue transport. > - The native runner has a separate verified file registration path that needs the same durable result. > - This pull request repairs legacy binary transport, makes native download receipts explicit, and reveals new outputs in the task Artifacts tab. > - Users can open generated files from either runner without a transport flag change. ## Linked Issues or Issue Description Refs #13355 for the existing native file publication path. Related filename fixes: #2615 and #4788. Related sandbox persistence work: #13376. This change repairs attachment delivery through the existing API; it does not add workspace persistence. **What happened?** The upload helper first lists task attachments to avoid duplicates. Both legacy bridge allowlists rejected that GET request with 403. A direct multipart upload also failed: the queue bridge accepted only JSON, excluded attachment uploads, and converted bytes to UTF-8 text. Enabling HTTP/2 alone did not fix the missing listing route. These failures occurred before attachment storage. **Expected behavior** Both runners can publish a workspace file, register its work product, bind it to a response, and return a working download. The file stays accessible after sandbox deletion. A new output opens the task Artifacts tab. The agent receives accurate errors and decides how to retry or report a failure. **Steps to reproduce** 1. Run a legacy agent in Daytona with the duplex bridge disabled. 2. Invoke the bundled upload helper with Bash on a PNG or PDF. 3. Repeat with the duplex bridge enabled. 4. Register the same file through the native runner with generic API tools disabled. 5. Retry registration, delete the sandbox, and compare the downloaded bytes with the original file. **Paperclip version or commit** The failing baseline was `f2c5e54dc`. This branch is rebased onto `6cfe4acff`. **Deployment mode** Source checkout with a local API and real isolated Daytona sandboxes. ## What Changed - Allow authenticated attachment listing, upload, and content download through both legacy bridge transports. - Add optional base64 body encoding to queue envelopes. Preserve the existing UTF-8 contract when the encoding field is absent. Decode binary bodies before forwarding them. - Preserve multipart headers. Bound raw bytes, encoded envelopes, and in-flight reservations. Retain timeout and uncertain-write behavior. - Preserve helper deduplication and return structured uncertain-write failures. Document explicit Bash invocation in live skills. - Add attachment IDs and content/download paths to native registration receipts. Reuse verified local and remote file reads, attachment storage, work-product registration, and response binding. - Preserve Unicode upload filenames and provide a valid Content-Disposition header. - Open the task Artifacts tab when new stored outputs arrive, including a closed desktop panel or mobile drawer. Deduplicate upload and registration events by object ID. Preserve manual selection on refetches, edits, and panel remounts. - Remove task artifact filters, the company Artifacts footer link, and the unassigned group heading and timestamp. ### Screenshot  This is the local display fixture. The image was generated separately and published through the attachment and work-product APIs. ## Verification - Post-rebase `pnpm -r typecheck` and `pnpm build` pass. - The post-rebase local `pnpm test:run` passed 12,369 tests before one existing conversation reset test timed out; all 33 tests in that suite pass when rerun with isolated test configuration. The aggregate command stopped before its remaining groups. GitHub runs the complete suite in separate shards. - All [GitHub verification checks](https://github.com/paperclipai/paperclip/actions/runs/35017893350) pass on `b66ac276dd3d5fc738a22ecea783400106a494d4`: 32 successful checks and two configured skips. The native-session recovery assertion initially raced its fire-and-forget Sentry report; all 13 tests pass locally, and the same-commit CI rerun passes all 170 suites (3,079 tests). - Live post-rebase Daytona: all three file-delivery tests pass. They cover the real Bash helper with the queue bridge, the helper with HTTP/2, and native `register_deliverable` with generic API tools disabled. - Daytona cases cover PNG/PDF bytes, spaced and Unicode names, duplicate registration, response binding, authorization controls, and byte-for-byte downloads after sandbox deletion. - Local focused coverage includes transfer bounds, malformed encoding, interrupted transfers, remote path containment, and native file verification. The attachment route suite passes all 32 tests, including an eight-case filename-header matrix for Unicode and special characters, inline and forced downloads, and full and partial responses. - Browser verification confirms image previews, persisted downloads, automatic Artifacts selection, and preserved manual selection after edits and reloads. Desktop/mobile component coverage passes. The latest UI cleanup passes its 10 affected tests and token gates. - Coverage limit: the Daytona tests call the real helper and native registration path directly. They do not replay a complete model-led image-generation task through the browser. Live command (requires a configured Daytona credential): ```sh PAPERCLIP_FILE_DELIVERY_DAYTONA=1 pnpm exec vitest run server/src/__tests__/file-delivery-bridges.test.ts ``` ## Risks - Binary queue bodies use more memory because base64 adds encoding overhead. Transfer and process limits must remain aligned. - An interrupted write can have an unknown result. The bridge reports this state and preserves stable retry identities. - New artifacts intentionally change the active task tab. Existing history and repeated updates must not take focus again. - Transport flag defaults, server authorization, frozen skill snapshots, and completion policies remain unchanged. No schema migration is required. ## Model Used OpenAI Codex, based on GPT-6, with reasoning, repository tools, code execution, and browser testing. The runtime does not expose a more specific model ID 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 `#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>
