ci(bandscope): stage central isolated Linux quality gates

[seonghobae]

Current authority — October 10, 2026

• OPEN / Ready for review; exact head 44a140e00d298abaf4dccdc4b073930adff5a097, tree 5807585e2fe441b841cf7015f9ee91175f594ce4.
• Ordinary merge parents: predecessor 49c1868d57236359485634042cee375d85d001c3 and canonical ci: stage all workflows on isolated self-hosted runners #2565 ef0c9d4c668fac7f01609b8fbd61a4126b103f5c. No force push or rebase.
• Independent bounded source review passed. Full local warning-fatal tests: 5629 passed, 4 skipped, 85 subtests passed; exit 0, source unchanged. Four skips are not PASS. Coverage and remote qualifying gates are separate.
• Canonical actionlint and BandScope contract 46 cases passed. Exact custom label was registered without changing runtime runner admission.
• Ready transition requested existing review execution; no duplicate dispatch. New Noema run 38060106973 and OpenCode run 38060106978 are pending; no current-head APPROVED is claimed.
• Previous Noema 38058455385 / 114232006639 failed after Draft skipped model work because artifact storage quota was exhausted. It did NOT skip because of personal-route attestations. Trusted executed source was protected main 7554587c…; candidate routing is not deployed by this PR.
• Integrate personal S1 LiteLLM API into Noema, Strix and OpenCode Review #2560 / feat(review): route public reviews through LiteLLM auto #2621 own personal LiteLLM auto integration; fix(noema): skip draft sidecar artifact upload #2563 owns Draft upload repair; ci: stage all workflows on isolated self-hosted runners #2565 owns global runner migration. No competing key issuer or shared workflow repair is created here.
• NO ACTIVATION: no BandScope caller, ACL/capacity/canary, required-check replacement, personal inference, formal App approval or protected merge is claimed.

The stack and test receipts below are historical; their old head and Draft descriptions do not describe the current state above.

Summary

• Stage a BandScope-specific central reusable workflow for the existing Linux lock-validation and verify commands.
• Preserve action/tool pins, read-only permissions, fixed repository and caller merge SHA; reject unknown gate values before checkout.
• Select only the isolated group and dedicated bandscope-ci label, without hosted/control-pool fallback.
• Use a unique step-owned numeric-wheel directory; reject missing, multiple, symlink, or directory outputs and retain failure exits.

NO ACTIVATION

No product caller, runner/ACL change, Secret mutation, or required-check change is included. Existing hosted workflows stay in place until equivalent execution is verified. Activation requires ContextualWisdomLab/linux-cluster-ops#326 and ContextualWisdomLab/quarantine-sandbox-runtime#136 operational isolation evidence, actual caller access, and a real canary. Windows/macOS amd64/arm64 gates remain mandatory.

Global routing remains owned by #2565; LiteLLM/model/App review remains owned by #2560. This PR inherits shared routing from the owner instead of carrying a competing copy. Model auto-configuration is not executed model-review evidence.

Canonical stack repair (2026-10-09)

• Previous exact head: e126b6f50e513019486f5b6879966af568dacdb8.
• Current exact head: 5d7fefa7e56300dfc8732929664ec199aa7fafa9; tree 1514f59370af630952cad2086b09ad60b973c2b4.

• Base is now ci/sdp-all-self-hosted-20261003. The child delta is exactly the three BandScope files plus test(codeql): keep current-time fixtures fresh #2609's current-time CodeQL fixture.
• Seven stale shared runner-policy conflicts were resolved byte-for-byte to ci: stage all workflows on isolated self-hosted runners #2565's canonical CWL CI isolated / cwlab-ci-isolated contract. No force push or destructive rebase was used.
• This PR is Draft because its canonical owner prerequisite ci: stage all workflows on isolated self-hosted runners #2565 remains mutable/unready. Missing approval and queued Checks are merge blockers only; they are not the Draft reason.

Verification

• Retained test-first slices: absent producer RED, then parsed YAML admission/numeric shell GREEN.
• Original exact-head disclosure retained: 5,204 passed, 6 failed, 4 skipped, 40 subtests; the same six failures reproduced on the exact base.
• Repaired exact-tree focused contracts: 210 passed normally and 210 passed with GITHUB_ACTIONS=true; separate runs.
• Repaired exact-tree full suite with PYTHONWARNINGS=error: 5,535 passed, 10 skipped, 40 subtests.
• All 39 workflow YAML files parsed; compileall and git diff --check passed.
• The remote intermediate and final tree SHAs matched the independently built local trees before the expected-head-protected fast-forward.
• Hosted exact-head Checks are running independently and are not replaced by local evidence.

NOT RUN

Real dependency installation/quickcheck, maturin wheel, GitHub caller execution, runner canary/admission, native four-platform builds, actual check-name mapping, and protected integration.

Security Notes

Same-repository PR code and build hooks remain untrusted. Context filtering and pre-checkout rejection do not prove pre-lease isolation. No supplied secrets, write/OIDC permissions, or generic command/ref/runner inputs are added; the automatic read-token boundary remains. Temporary-wheel cleanup is step-local, not VM teardown. Invalid admission gives a fixed diagnostic. Security Scan, CodeQL, audit, SBOM, and platform requirements are retained.

Concurrency follow-up delivered

Current head: e126b6f50e513019486f5b6879966af568dacdb8 (normal fast-forward push).

Reserved the reusable-only cwl-reusable-bandscope-linux- namespace. Repository/gate/PR coalescing, non-PR run ID, cancellation policy, commands, permissions and runner selectors are unchanged. The activation caller must use a different namespace; this is not a guarantee against an arbitrary caller intentionally selecting the same group.

Verification: test-first assertion RED (1 failure) → full scoped GREEN (45 passed); Ruff check/format, actionlint with custom-label catalog and diff check exit 0. Independent follow-up review deleg_511d52c6 passed on the exact three file hashes; parent compared the working tree, index and patch before commit. The previous head's checks/reviews are not transferred to this head.

The CodeRabbit thread is now resolved, as confirmed by fresh GraphQL. No formal current-head App approval or protected merge is claimed. This remains a staging producer: no BandScope caller, runner ACL, Secret, hosted retirement or runtime activation change.

Verified owner-stack repair — October 10, 2026

Current head: 44a140e00d298abaf4dccdc4b073930adff5a097; tree 5807585e2fe441b841cf7015f9ee91175f594ce4.

Ordinary merge parents are predecessor #2603 49c1868d57236359485634042cee375d85d001c3 and owner #2565 ef0c9d4c668fac7f01609b8fbd61a4126b103f5c. Normal fast-forward push; no force push or rebase.

Shared conflict resolution preserves exact owner bytes. The owner delta is five paths: the BandScope workflow/document/contract, the preserved #2609 time fixture, and a single exact bandscope-ci actionlint vocabulary entry. No runtime runner selector was weakened.

Independent source review deleg_448ad9a5 passed on the exact tree. Local warning-fatal full tests after correcting the private verification environment's missing hash-locked pip: 5629 passed, 4 skipped, 85 subtests passed, exit 0, 315.95 seconds. Parent verified JUnit (5633 cases, zero failures/errors), log digest and unchanged source before/after. This is not coverage or hosted acceptance. The four skips are HWP/HWPX reader fixtures, LLVM-19 tool availability, and the collected-release download fixture; they are not PASS.

The earlier incomplete full attempt and ambient-PATH numeric fixture timeouts remain historical failures. Pinning the actual verification interpreter and installing the already declared pip==26.2.1 offline fixed the observed environment boundary without changing tests or deadlines. Direct BandScope contract: 46 passed. Canonical actionlint and diff checks: exit 0.

NO ACTIVATION remains: caller, runner ACL/capacity, isolation canary, actual personal LiteLLM auto inference, formal current-head App approval and protected merge are not completed. Previous-head checks/reviews do not transfer to this push. Draft state is unchanged pending current stack readiness reconciliation.

[seonghobae]

PR #2603 is no longer Draft. I verified the current exact head first, then changed the PR state to Ready for review; the commit and source remain unchanged. Current head: 44a140e00d298abaf4dccdc4b073930adff5a097. This only requests review. It does not claim current-head approval, passing hosted checks, runner activation, or merge readiness.
