fix(ci): support admitted OpenShell SDK upgrades in trusted E2E - #14341
Manual PR E2E can prepare an independently admitted OpenShell SDK upgrade before compiling and running the candidate. The protected GPU controller retains its trusted dependency graph. If admission is revoked after preparation, verification rejects candidate use and cleanup restores trusted originals. Cleanup also reconciles a failed projection whose rollback failed.
Reason
PR #12603 selects SDK 0.1.7. Full E2E run 42696682762 failed before runtime because trusted preparation selected only older reviewed SDK packages. Restoration also depended on live approval, which could leave projected files behind after revocation.
Changes
Reuse candidate/base admission and SDK packaging for manual PR runs. Preserve reviewed packages for main and exact-base runs.
Pass PR identity through direct and reusable consumers. Remove API tokens before npm cache staging, dependency installation, and SDK import.
Verify the protected controller's SDK-only projection, unchanged dependency metadata and transitive graph, current approval, and archive bytes before staging. Ordinary consumers retain full candidate manifest and lock parity.
Pin SDK installer callers to implementation commit 855b8b80e13c4dbd59411672e3c3dd7720bc590f. Align workflow environment contracts, MCP read permissions, compile-action token expectations, and complete-object hashes without weakening their rejection cases.
Execute the inline manual-dispatch producer in a regression test. Assert candidate identity, API-token forwarding, the admitted artifact path, and rejection of the reviewed fallback for that admitted case.
Record dispatch identity and original/projected digests before projection writes in a mode-0600 receipt under trusted Git metadata. The existing restore CLI validates this receipt and all seven fixed destinations, then reads replacement bytes and modes only from the immutable trusted Git commit. This lets recovery proceed without live approval or the candidate checkout; preparation and verification retain live admission.
Keep completed trusted writes after a partial restoration failure so recovery can resume. Retain the receipt for idempotent recovery and replace it only after a later preparation validates clean trusted sources and admission.
Run workflow recovery with always() when preparation succeeded or a receipt entry remains. Preserve cleanup failure for missing required, malformed, or dangling receipts. Remove API credentials from restoration and bind its environment only to preparation outcome. Test the actual workflow shell with a real CLI after failed preparation and rollback; update the owning guidance.
Bind protected file reads and replacements to opened directory descriptors. Use the controller’s isolated Python standard library for descriptor-relative operations because Node lacks descriptor-relative rename. Projection, rollback, receipt publication, and restoration share the helper. Reject linked files, detached parents, and changed replacement preimages. Keep temporary creation, rename, and cleanup bound to the opened parent.
Verification
Directory-race repair: 56 workspace cases and 22 filesystem cases passed. These include real descriptor-bound reads/writes, directory swaps at parent/file/temp/rename boundaries, root detachment, matching-content leaf links, external-file preservation, descriptor cleanup, credential isolation, and recovery after rejection.
The Python watch mapping passed 94 cases; seven growth guardrails passed. All 19 repository checks, scoped Oxlint/Oxfmt, source-shape checks, and the installed pre-commit/commit-message hooks passed. No test deadline or live assertion changed.
Three deliberate attachment/root/leaf-protection mutations each failed the regression suite. Original source was restored after every probe. The same directory-swap reproduction succeeded against both recorded base and previous candidate before the repair.
The earlier SDK producer and cleanup-caller selections remain recorded in the prior review history. This repair preserves their admission, archive, workflow, and receipt contracts.
Final publication commit: 13fd0f4ecba328e95383a2f5b86e744208cd52b2. Actual isolated publication hooks passed, including publication validation and the applicable CLI type check. Fresh branch and PR readbacks match this commit, and all seven commits have valid GitHub verification. Source CI 42760095761, security 42760096034, and managed images 42760095782 passed. All nine Advisor specialists and the blocker gate passed in 42762557930. CodeRabbit review was requested for this final commit and remains pending. Gitleaks passed; the diff includes no secrets or credentials.
Previous candidate 32b47b1 passed source CI 42742397422, security 42742397403, managed images 42742397502, and CodeRabbit. Runtime activation passed on amd64, arm64, and rootless Podman. Those passes do not establish the new candidate’s results. This PR does not complete PR #12603’s Pi native-local qualification.
Review notes
The user authorized both receipt-based restoration after revocation/failed preparation and repair of the inherited directory race. Advisor 42744943062 completed all nine specialists on 32b47b1: eight were clear, including recovery and verification. Its security P1 F-security-built-in-quality-bcb22538ebbd4723fab0 is addressed by this descriptor-bound repair, confirmed clear by the security, recovery, and verification specialists in the current Advisor run. The old failed gate was not waived or rerun unchanged.
The sensitive paths received local source/security review across SDK admission, credential custody, all seven recovery destinations, descriptor attachment, partial writes, rollback, and cleanup. The receipt cannot supply replacement bytes or authorize candidate execution; immutable trusted Git blobs remain the source authority. The filesystem child receives no inherited environment and installs no dependencies. Tests execute the real helper with deterministic syscall interleavings. The PR remains draft pending CodeRabbit review; copied-branch self-hosted qualification and independent maintainer review remain necessary. Advisor recommends the existing managed-image-protected-runtime job as additional operational evidence. That recommendation does not independently authorize or require manual full E2E under the publication contract; no manual qualification is claimed here.
CodeRabbit’s inherited multiarch extra-permission validator concern remains advisory; actual permissions remain read-only. Fallback execution cases and an explicit missing-step diagnostic remain deferred test improvements. Proposed redirect-policy hardening remains advisory. CodeQL posted two duplicated descriptor-close warnings. They are false positives: each successful parent-directory open immediately registers os.close with contextlib.ExitStack, which closes all acquired descriptors on normal and exceptional context exit. The real helper’s hard-link rejection test records every acquired descriptor and verifies that all close. No warning suppression, gate waiver, or maintainer approval is claimed.
Attempted top-level invocations, including failures, through cutoff. Dynamic exec wrappers hide nested invocations; those are not added to these counts.

Persisted turn contexts through cutoff. Independent review reused the existing reviewer.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Manual E2E runs can select an SDK candidate using upgrade PR and revision inputs. The workflows conditionally package and prepare candidate SDKs, validate admission and protected workspace state, and stage archives. Recovery uses receipts to restore trusted files. Workflow boundary checks validate token conditions, permissions, and reviewed action revisions.
E2E workflows pass upgrade identifiers to candidate packaging. Candidate admission applies to qualifying dispatches, and install preparation validates the API token. Tests cover admission conditions, token expectations, packaging, and import paths.
Protected preparation checks SDK admission and workspace state before and after reviewed npm preparation. It stages archives only when inspections match. Receipt-based restoration validates trusted inputs and restores trusted committed files. Tests cover staging, filesystem safety, and recovery behavior.
The E2E workflow attempts restoration after success or when a recovery receipt exists. Boundary checks validate input propagation, packaging behavior, token conditions, restoration conditions, and read permissions. Execution fingerprints and documentation reflect the workflow contracts.
This change extends E2E SDK admission and receipt-based recovery. The remaining issues are small: tighten the workflow permission validation, and optionally document the replacement race and improve one test. Owners should be aware of these, but they should not block merge.
Security architecture risk: Low · up to 13fd0
The inspected paths preserve independent approval, separate admission credentials from dependency execution, and restore trusted files without renewed approval. No introduced security bypass was established. Residual risk centers on recovery-state ownership and incomplete confirmation of operational isolation.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The security-sensitive surface includes shared SDK artifacts consumed by multiple E2E profiles, the protected GPU controller's seven projected files, and dependency-cache staging. The protected job grants contents-read and pull-request-read permissions; candidate source remains in a separate checkout.
Trust Boundaries and Controls
observed — GitHub API authority is used by trusted admission code. Preparation removes GitHub token variables before staging; cache staging also removes npm credentials. The installation wrapper unsets GitHub tokens before npm ci and disables lifecycle scripts, and the SDK import probe explicitly removes GitHub and package credentials.
observed — Inference API secrets are still supplied to selected E2E runtime commands under trusted_main. This runtime credential contract exists in the PR base; it is distinct from admission-token isolation and is not treated as a newly introduced exposure.
Resilience and Maintainability Implications
observed — Recovery metadata identifies expected workspace state but cannot supply replacement executable bytes or arbitrary destinations. Restore uses the fixed path list and original committed blobs, so approval revocation need not block restoration and a receipt cannot itself authorize candidate execution.
Hardening Proposals
proposed — Document or enforce exclusive single-writer ownership of each protected checkout before reusing the manager in concurrent callers. A workspace-level lock would prevent separate operations from overwriting the shared receipt while interleaving file transitions. This is a reuse safeguard, not a demonstrated attack path in the inspected sequential workflow.

Document, or close, the check-then-replace gap before publication.
Line 99 rechecks that the destination still matches expected. Line 102 then calls os.replace, which overwrites the destination unconditionally. A writer that modifies name between those two lines has its change silently discarded. The descriptor chain pins the directories but does not pin the file content. This helper also does not hold any lock that other writers must respect.
The README says only that "replacements recheck the expected source before publication". It does not state this residual window.
Choose one of these fixes:
State the residual same-UID race in test/e2e/README.md, with the assumption that no other writer touches these paths during the step.
Detect the race. Rename the original to a unique backup name with os.rename. Read the backup and compare it to expected. Publish with os.link(temporary, name, ...), which fails if name exists. Restore the backup if the comparison fails.
Based on learnings: "do not assume the atomicity itself enforces that the target is unchanged since revalidation ... use a true conditional/compare-and-swap primitive ... or coordinate all writers, otherwise fail closed."

Replace the mock-call assertions with a behavioral isolation test.
This test inspects the arguments that execFileSync received: -I, -S, env: {}, and the stdio shape. That locks in the implementation and does not prove isolation. The test would still pass if the helper imported attacker-controlled code in another way.
Test the outcome instead:
Create a temporary directory that contains a json.py module. The module writes a marker file when imported.
Set PYTHONPATH to that directory with vi.stubEnv.
Call safeFile.
Assert that the read succeeds and that the marker file does not exist.
For credentials, assert the observable result. For example, run the probe with a prelude that fails if os.environ is non-empty.
As per path instructions: "Prefer observable outcomes through the public boundary over source-text, private-shape, or mock-call assertions."

Outcome
Manual PR E2E can prepare an independently admitted OpenShell SDK upgrade before compiling and running the candidate. The protected GPU controller retains its trusted dependency graph. If admission is revoked after preparation, verification rejects candidate use and cleanup restores trusted originals. Cleanup also reconciles a failed projection whose rollback failed.
Reason
PR #12603 selects SDK 0.1.7. Full E2E run 42696682762 failed before runtime because trusted preparation selected only older reviewed SDK packages. Restoration also depended on live approval, which could leave projected files behind after revocation.
Changes
Reuse candidate/base admission and SDK packaging for manual PR runs. Preserve reviewed packages for main and exact-base runs.
Pass PR identity through direct and reusable consumers. Remove API tokens before npm cache staging, dependency installation, and SDK import.
Verify the protected controller's SDK-only projection, unchanged dependency metadata and transitive graph, current approval, and archive bytes before staging. Ordinary consumers retain full candidate manifest and lock parity.
Pin SDK installer callers to implementation commit
855b8b80e13c4dbd59411672e3c3dd7720bc590f. Align workflow environment contracts, MCP read permissions, compile-action token expectations, and complete-object hashes without weakening their rejection cases.Execute the inline manual-dispatch producer in a regression test. Assert candidate identity, API-token forwarding, the admitted artifact path, and rejection of the reviewed fallback for that admitted case.
Record dispatch identity and original/projected digests before projection writes in a mode-0600 receipt under trusted Git metadata. The existing restore CLI validates this receipt and all seven fixed destinations, then reads replacement bytes and modes only from the immutable trusted Git commit. This lets recovery proceed without live approval or the candidate checkout; preparation and verification retain live admission.
Keep completed trusted writes after a partial restoration failure so recovery can resume. Retain the receipt for idempotent recovery and replace it only after a later preparation validates clean trusted sources and admission.
Run workflow recovery with
always()when preparation succeeded or a receipt entry remains. Preserve cleanup failure for missing required, malformed, or dangling receipts. Remove API credentials from restoration and bind its environment only to preparation outcome. Test the actual workflow shell with a real CLI after failed preparation and rollback; update the owning guidance.Bind protected file reads and replacements to opened directory descriptors. Use the controller’s isolated Python standard library for descriptor-relative operations because Node lacks descriptor-relative rename. Projection, rollback, receipt publication, and restoration share the helper. Reject linked files, detached parents, and changed replacement preimages. Keep temporary creation, rename, and cleanup bound to the opened parent.
Verification
13fd0f4ecba328e95383a2f5b86e744208cd52b2. Actual isolated publication hooks passed, including publication validation and the applicable CLI type check.

Those passes do not establish the new candidate’s results. This PR does not complete PR #12603’s Pi native-local qualification.Review notes
The user authorized both receipt-based restoration after revocation/failed preparation and repair of the inherited directory race. Advisor 42744943062 completed all nine specialists on
32b47b1: eight were clear, including recovery and verification. Its security P1F-security-built-in-quality-bcb22538ebbd4723fab0is addressed by this descriptor-bound repair, confirmed clear by the security, recovery, and verification specialists in the current Advisor run. The old failed gate was not waived or rerun unchanged.The sensitive paths received local source/security review across SDK admission, credential custody, all seven recovery destinations, descriptor attachment, partial writes, rollback, and cleanup. The receipt cannot supply replacement bytes or authorize candidate execution; immutable trusted Git blobs remain the source authority. The filesystem child receives no inherited environment and installs no dependencies. Tests execute the real helper with deterministic syscall interleavings. The PR remains draft pending CodeRabbit review; copied-branch self-hosted qualification and independent maintainer review remain necessary. Advisor recommends the existing managed-image-protected-runtime job as additional operational evidence. That recommendation does not independently authorize or require manual full E2E under the publication contract; no manual qualification is claimed here.
CodeRabbit’s inherited multiarch extra-permission validator concern remains advisory; actual permissions remain read-only. Fallback execution cases and an explicit missing-step diagnostic remain deferred test improvements. Proposed redirect-policy hardening remains advisory. CodeQL posted two duplicated descriptor-close warnings. They are false positives: each successful parent-directory open immediately registers os.close with contextlib.ExitStack, which closes all acquired descriptors on normal and exceptional context exit. The real helper’s hard-link rejection test records every acquired descriptor and verifies that all close. No warning suppression, gate waiver, or maintainer approval is claimed.
