errors containing “error during connect” with “dial tcp” or “connection refused”
take precedence over the broader runner-network pattern. Reorder the matching
rules or encode explicit precedence, and add a test covering the mixed-signal
message to assert it returns daemon behavior.

Reviewed exact head a46bc6b. One correctness blocker remains: daemon connection failures that also contain broad network phrases are classified as runner network because the first-match table evaluates the network rule first. That can send operators to the wrong failure layer. Define daemon precedence and cover a mixed-signal message. Product scope, commit verification, DCO, secret handling, and the nine-category security review are otherwise clean; the exact-head focused installer suite passed 38/38. Current CI and automated review are still settling.

[P2] Preserve daemon-error precedence. The classifier returns the first matching layer, but runner network is checked before daemon behavior. Real Docker errors commonly combine error during connect with dial tcp or connection refused, so those daemon failures are mislabeled as runner network. Move the daemon-specific rule ahead of the broad network rule, or encode explicit precedence, and add a mixed-signal regression that expects daemon behavior.

Reviewed exact head 2634729. The original daemon-precedence blocker is fixed and the mixed-signal regression passes. One new security blocker remains in the added diagnostic excerpt: pattern-based redaction cannot make arbitrary Docker or credential-helper output safe to echo. Keep the bounded causal evidence required by #10558, but derive it from allowlisted failure signatures/structured fields (or otherwise fail closed) and add opaque credential-helper-output coverage. Exact-head focused installer tests pass 38/38, CLI type-check passes, all seven commits are GitHub Verified, DCO is green, and the exact-head live generic-GPU E2E passed. Required CI is separately red only on the known SDK-package orchestration defect fixed by approved #10568.

[P1] Do not echo pattern-redacted third-party pull output. Docker credential-helper failures can include arbitrary helper text (for example, error getting credentials - err: exit status 1, out: followed by an opaque value), and redactFullWithUrls does not remove values that are not credential-shaped. This path therefore copies an attacker/helper-controlled secret into onboarding output and the E2E artifact. Preserve #10558's bounded causal evidence using allowlisted matched signatures or structured fields rather than the whole stdout/stderr/error tail, and add a regression proving an opaque helper value never reaches the returned reason or logs.

Re-reviewed current head 249e92b. The new warning text does not resolve this blocker. An exact-head reproduction passes error getting credentials - err: exit status 1, out: opaque-pull-secret through redactFullWithUrls unchanged, and imagePullFailureDiagnostic still copies that arbitrary value into the returned failure reason and E2E artifact. The exact-head PR Review Advisor trust specialist independently reports the same blocker. Keep only allowlisted or structured classification evidence and add an opaque-value regression covering the returned reason, logs, and captured artifact. Exact-head local verification: installer/redaction 112/112, secret-redaction integration 43/43, workflow planning 87/87, and CLI type-check all pass; the obsolete E2E bridge removal is otherwise clean.

Reviewed exact head 40730bd585c085faeb718e5fcbc583094b8b79c5. The original P1 is resolved: pull stdout, stderr, thrown-error text, streaming callbacks, and opaque helper values are suppressed from the returned reason, installer log, and downstream artifact; only fixed allowlisted layer/code values and process status remain. All 11 commits are GitHub Verified, DCO is green, the focused installer/redaction/diagnostics suites pass 142/142, the isolated compiled-redactor integration replay passes, CLI build and type-check pass, and the nine-category security review is clean. I verified the other exact-head Advisor suggestions are not blockers: the proposed shared formatter still pattern-redacts arbitrary third-party output and would recreate the leak; the Ollama restart block is whitespace-identical to main; and the injected pull seam predates this PR. One new behavior branch still needs the inline regression below. Exact-head full CI and CodeRabbit are also not yet settled.

[P2] Cover a failed pull with no process status
imagePullFailureDiagnostic now has a distinct status === null path for spawn failures, but every row here supplies a numeric status and the assertions do not protect Exit status unavailable.. A capture can return { status: null, error }; without this boundary case, a regression could omit the classification or accidentally treat the failed spawn as success while this suite stays green. Add a row (or one focused case) with status: null plus a classified error, and assert the fixed classification, Exit status unavailable., failed installation, and absence of the raw error payload.

Approved exact head 64945418158bbd553b9d43017de7e363f10947fc. The requested status: null regression is no longer applicable: this commit removes the test-only pull seam and uses the production ContainerEngine result contract, which always normalizes command status to a number. Pulls now run through the qualified host-local-inference engine, while failure output remains confined to in-memory classification and only fixed layer/code/status text escapes.
All 12 commits are GitHub-verified; DCO and every required check are green; current CodeRabbit and PR Review Advisor runs are complete. The Advisor request to retain normalized raw causal text is unsafe for opaque credential-helper values and would recreate the original leak, so it is not actionable. The Ollama restart suggestion targets a block unchanged by this PR; the current diff only removes the obsolete compatibility bridge. Exact prior-head local installer/redaction evidence passed 142 tests, and the current exact-head GitHub build/typecheck is green.
Nine-category security review: Secrets and Credentials PASS; Input Validation and Data Sanitization PASS; Authentication and Authorization PASS; Dependencies and Third-Party Libraries PASS; Error Handling and Logging PASS; Cryptography and Data Protection PASS; Configuration and Security Headers PASS; Security Testing PASS; System Security PASS.

Outcome
Pinned managed llama.cpp image pull failures now report a fixed failure layer, an allowlisted diagnostic code, and exit status instead of stopping with an opaque pull error. Raw pull output never crosses into installer logs or E2E artifacts. The generic GPU live E2E keeps one proof for each real external boundary while falling from 552 to 397 lines and from 70 to 29
expectcalls.Reason
The failed full-main run discarded the pull response, so its root cause cannot be reconstructed. A later occurrence must distinguish authentication, storage, runner network, invalid dependency, registry availability, daemon behavior, or an honestly unclassified result without exposing arbitrary registry, credential-helper, or daemon output. The live target also repeated deterministic catalog, state, runtime-argument, status, and third-party log assertions that obscured its end-to-end contract.

GitHub checks own current-head qualification after the conflict-free base refresh.249e92bc68passed, including the generic NVIDIA GPU live target, artifact upload, and cleanup. Exact final-head qualification is pending.Review notes
The live target was not run locally because it mutates real Brev, Docker, GPU, and OpenShell state. GitHub's prior-head qualification passed the external gate; exact final-head qualification is pending.
Deterministic ownership already exists for removed assertions: serving catalog and package contracts own recipe and image identity; host-local runtime and managed lifecycle tests own entrypoint arguments; managed status tests own status and doctor rendering. Third-party startup wording has no replacement assertion. Docker logs remain artifact evidence only.
The historical failure remains root-cause unknown because its raw pull response was not recorded. This PR deliberately references rather than closes #10558. A later recognized signature will provide a credential-safe failure layer and diagnostic code for the root-cause fix; an unknown signature remains honestly unclassified.
