## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Native runners start provider processes and enforce a separate tool environment policy. > - The server resolves task environment bindings at each run boundary. > - Fixed launch allowlists dropped custom variables after resolution. > - Warm process reuse and a blanket fingerprint exclusion also hid configuration changes. > - This pull request carries a bounded, server-selected list of task variable names through each process boundary. > - The benefit is that later turns and tool commands receive configured values while ambient host secrets stay excluded. ## Linked Issues or Issue Description **What happened?** A native Codex agent could not use configured task credentials. Adding the variables in Settings did not fix the next turn. The provider sanitizer, runner launch, Rust provider launch, and shell policy each used fixed allowlists. Effective config fingerprints also excluded all variables with the `PAPERCLIP_` prefix. **Expected behavior** Explicitly bound task variables must reach provider processes and tool commands. Added, changed, and removed values must take effect at the next run boundary. A running turn keeps its original configuration. **Steps to reproduce** 1. Start a native Codex task without a custom environment binding. 2. Add a fake `PAPERCLIP_PAGE_BUCKET` value and a fake Pages credential binding in Settings. 3. Continue the task and inspect the tool environment. 4. Before this fix, those values are absent even from a fresh runner launch. **Paperclip version or commit** Reproduced at `b31558064`. The fix is rebased on current master. **Deployment mode** Self-hosted server with a native process runner. Related changes: [the legacy Codex MCP environment fix](https://github.com/paperclipai/paperclip/pull/13321) and [ambient server-secret exclusion](https://github.com/paperclipai/paperclip/pull/12870). These affect different launch paths. This change preserves their credential boundaries. ## What Changed - Capture scoped task bindings after resolution, before managed provider credential injection. Mint and validate the names-only projection at native dispatch before host inheritance. Legacy adapters retain their previous environment limits. - Strip user-supplied projection markers from agent, environment, project, and routine config. - Carry selected values through the Codex, ACPX, OpenCode, runnerd, and Rust subprocess launch boundaries. - Add selected names to native and ACPX Codex shell include lists. Keep selected values out of command arguments, including selected bootstrap values. - Reject malformed projections, reserved authority and loader names, missing values, null bytes, and oversized input. - Replace a retained native process when projected values change. Keep unchanged processes reusable. - Fingerprint custom namespaced variables while excluding known generated runtime variables. - Document next-run behavior and add regression coverage. ## Verification - Red: the permanent reproduction failed at four launch/tool boundaries and the namespaced fingerprint check. Two control checks passed. - Green: the initial regression plus existing Codex environment and shell tests passed (39 tests). - Server config resolution, fingerprints, and native-session suites passed (653 tests), including addition, rotation, removal, and unchanged warm-session reuse. - Rust regression tests passed. A real shell child received added and rotated values, then lost them after removal. Unselected host variables stayed absent. - `pnpm -r typecheck` and `pnpm build` passed after rebase. The full `pnpm test:run` was attempted but could not complete: fresh embedded PostgreSQL databases fail during bootstrap on this macOS host. An isolated suite and a disposable native `initdb` probe reproduced the failure before test execution. `shmget` reports `No space left on device` because the host has exhausted shared-memory IDs. This is not disk exhaustion. The run was stopped after confirming the external setup failure. CI results will be recorded separately. - Runner boundary suites: 361 tests passed. Two process-launch errors during concurrent binary staging passed on isolated rerun. - Rust Codex provider and process supervisor integration suites: 97 passed, 2 intentionally ignored. - ACPX shell and selected-bootstrap argv regressions: 3 failed before the fix, then all 55 relevant tests passed. - Review compatibility regression: 129-variable and large-value legacy configurations failed before the correction and passed after moving native-only validation to dispatch. - Final review head `3f11e8d25`: repository typechecks and production build passed. CI completed its implementation checks; one general-server shard hit SQL `40P01` in `heartbeat-runtime-skills.test.ts` during its `beforeEach` table truncate (1,199 tests passed in that shard). The shard passed on its single rerun. All CI checks for this head are green. Greptile reviewed this head at 5/5 with no new actionable findings; the compatibility thread is resolved. - No live provider credentials or model calls are required by these tests. ## Risks - Configured task credentials now reach the tools they were configured for. The controller selects names only after existing scope and secret-binding authorization. - TypeScript and Rust validate the same bounded projection. Their reserved-name rules must stay aligned. - A changed projection replaces an idle provider process. Unchanged values preserve reuse. Active turns retain their original environment. - No database migration or API schema change. > This fixes existing runner configuration behavior. It does not add a new roadmap capability. ## Model Used - OpenAI GPT-6 (Codex), with reasoning, local code execution, and repository tools. The session does not expose a more specific API model identifier 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>
