## Outcome OpenClaw auto-pair scheduler tuning can no longer crash the in-sandbox watcher or create effectively unbounded work. The five numeric controls now share one grammar and practical limits across CLI launch rendering, the managed startup transaction, the image entrypoint, and the watcher itself. Invalid operator values fail before sandbox creation. Direct container environment overrides retain the watcher’s fail-soft behavior, fall back to documented defaults, and emit one redacted warning that names the variable and default without echoing the rejected input. ## Reason The supported CLI path previously forwarded these values without numeric validation, and direct container environment overrides reached the watcher without an equivalent guard. Non-finite values could raise `OverflowError`; fractional poll counts could be truncated; and technically valid but extreme values could keep a watcher or child command alive far beyond an operationally useful lifetime. ### Related issues Fixes #11161 ## Changes - Define one typed contract for the five live `NEMOCLAW_AUTO_PAIR_*` numeric controls. Seconds accept finite decimal/scientific notation within their consumer limits; polls accept positive integers only. - Enforce the contract in CLI launch rendering and the managed application-environment transaction. - Validate the complete assignment vector in the image entrypoint before exporting any value, using the image's fixed `/usr/bin/python3 -I` runtime with values passed only through `argv`. - Revalidate direct environment overrides inside the watcher and warn on each nonempty rejected value without logging it. Bound the watcher lifetime to 24 hours, command timeouts and polling intervals to 300 seconds, intervals to at least 0.05 seconds, and fast-reentry polls to 1,728,000. - Cap every command and sleep by the remaining watcher deadline, and include the effective limit in timeout and expiry diagnostics. - Remove the unused `NEMOCLAW_AUTO_PAIR_FAST_DEADLINE_SECS` surface instead of continuing to validate and forward a value with no consumer. - Keep supervisor recovery fail-soft when reconstructing a launch from environment values that no longer validate. - Update operator documentation, regression coverage, the reviewed managed-startup bundle, and exact Pi qualification receipts. ## Verification - `npm run validate:pr` — passed on `c366b7a99a5cfec131b1a20845e80c8e566860d3`. - Full owning watcher suite — 119 passed; the focused fallback, deadline-clamped sleep, and deadline-clamped command cases passed. - Affected CLI and managed-startup suites — 364 passed. - MCP/receipt contract and Hermes image-probe tests — 76 passed on the final local head. - `npm run docs` — 0 errors; 5 pre-existing warnings. - Pi candidate build artifacts from [managed-images run 34414228186](https://github.com/NVIDIA/NemoClaw/actions/runs/34414228186) — Linux AMD64 and ARM64 jobs passed and the checked-in receipts are byte-identical to their uploaded contracts. - The diff contains no secrets, API keys, or credentials. ## Review notes The checked-in Pi receipts intentionally name source revision `91b0bfb7f6bf491d8dadb7ec939f874164bcd882`, the source commit built by workflow run `34414228186`; `446b203981f8b082304a81741c7ed8584efaf334` is the later receipt-only authority commit, and `964c1d20fd76fdad3bc7f2c3c4ccca7c2cffdea5` synchronized the first CI support-base refresh, `aeca39cb5b5517794efd65944aee9ab5699065cb` added receipt-authority regression coverage, and `d1621f82961091add86dffcac0814dc29910d70f` synchronized the first #11319 review fix, `ad2f7fbc0731e3755e85348648f32bcf281e38e1` synchronized its first APT sandbox correction, `5a54252f30d1bf00a1a90512583ec25e718b094c` addresses the latest Advisor findings, and current head `c366b7a99a5cfec131b1a20845e80c8e566860d3` synchronizes the final CI support fix. None of those later commits changes Pi image sources. Both receipts use cohort `ghrun-34414228186-1`; their file SHA-256 values are `f8ad7a0fede3401e9354a7a5b2f0d8feee139e591776a2585fdb849f3ebe2c16` (AMD64) and `1f467b5b715c9940e2e60545de7962c842e7d9591d33dc99385fe41f6580181a` (ARM64). The repository parity gate confirms there is no Pi image-source change from the recorded source revision through the current head. Requiring a receipt to name its own receipt-only commit would be self-referential and is not the repository contract. Both actionable Advisor findings from run `34411561376` are addressed: entrypoint numeric validation matches host/watcher whitespace handling, and the earlier duplicate watcher harness was consolidated. The latest Advisor run `34421886187` found two more issues; `5a54252f30d1bf00a1a90512583ec25e718b094c` removes the one-use 230-line scheduler probe layer, keeps the focused behaviors in the owning complete-watcher tests, and adds the redacted direct-environment fallback warning. The verification specialist’s evidence finding from Advisor run `34417334129` is addressed by testing both committed Pi receipts through the real published authority and runtime consumer, including exact digest and platform identity. The automatic Advisor rerun and final recommended E2E executions remain in progress. Independent CI/CD defects encountered while validating this PR were kept separate: #11314 and #11338 are merged, #11319 is the current stacked base, and #11322 remains a draft follow-up for the public CLI version timeout. --- Signed-off-by: Hai Nguyen <haingu@nvidia.com> Signed-off-by: Julie Yaunches <jyaunches@nvidia.com> --------- Signed-off-by: Julie Yaunches <jyaunches@nvidia.com> Co-authored-by: Julie Yaunches <jyaunches@nvidia.com>

Outcome
CI CLI shards and the PR Review Advisor now install their pinned search tools through one trusted helper. The helper selects the runner's configured
ubuntu.sourcesfile, disables source fragments, and uses fresh isolated APT package-list state. An inconsistent preinstalled third-party APT repository can no longer break these jobs before tests begin.Reason
On September 9, 2026, Google Chrome's APT repository entered a temporary inconsistent state: its signed metadata and CDN package index did not match, so Ubuntu correctly rejected the update with
Hash Sum mismatch.NemoClaw does not consume Google Chrome packages in these jobs. However, GitHub's Ubuntu runners include that third-party repository, and the jobs updated every configured APT source before installing
fd-findandripgrep. The external outage recovered, but it exposed an unnecessary CI dependency on every preconfigured repository.Fixes #11320.
Changes
/etc/apt/sources.list.d/ubuntu.sources, disables source fragments, and gives both APT operations fresh isolated list state.RUNNER_TEMP, temporarily grant traversal while APT runs, and restore the exact original mode on every exit.main; the live diff contains only the eight implementation and contract files for this fix.Verification
