The Apple wrapper is byte-identical to baseline: background `/Volumes/installstate/readiness.sh` then `exec /usr/libexec/recoveryosd` under the same launchd job/PID. Source evidence does not prove Apple's executable ran.
The disk IPC continuation contains seven explicitly marked diagnostic blocks and limits disk enumeration to one attempt. Its disk query receives 120 seconds so the owned sample can finish while the query is still running. Validation removes only those marked blocks, including that command-budget exception, restores the former attempt condition and normalizes macOS 13 to 14 before requiring baseline SHA256 `4d428f594dac14eff64ed87b172c81ecf85ac91da8c5460cd6ec4b1d310800c3`. The receipt explicitly records the exclusions, attempt limit and sample/query budgets. Architecture, UID, native service exits, disk size/writability/uniqueness, proof bounds and native-wait/cleanup/flush metrics remain identical. All other required native commands retain 45 seconds, UID retains 180 seconds, and outer limits remain ten minutes maximum disk readiness, 40 minutes host and 45 minutes workflow.

Two separate named version marker pairs exclude the new parser and explicitly restore the original three-line `sw_vers -productVersion` sequence for this baseline comparison. The receipt records this version-source exception, the 1,024-byte parser bound and all existing diagnostic budget exceptions. Architecture, UID, native service exits, minimum macOS version, disk size/writability/uniqueness, proof bounds and native-wait/cleanup/flush metrics remain identical. All other required native commands retain 45 seconds, UID retains 180 seconds, and outer limits remain ten minutes maximum disk readiness, 40 minutes host and 45 minutes workflow.
Run 4186 at `227884723a25e703ec1be39f8600eeaae2085c4f` completed native `sw_vers` successfully after 43 seconds, reporting macOS 13.6 / 22G120. The redundant `sw_vers -productVersion` then timed out after 48 seconds before any disk query. The continuation extracts exactly one `ProductVersion` field from the entire already-successful `platform` or `platform-warm` output. It requires EOF within 1,024 bytes, rejects NUL delimiters, duplicate/missing fields and malformed version suffixes, and accepts only two or three numeric version components separated by dots with native tab/space padding. The existing macOS 13 minimum remains mandatory; no native timeout is relaxed by this reuse.
Run 4175 at `94a70b200508d3ba295124896d923fbb785d1658` reached macOS 13.6, x86_64 and UID 0 with KVM enabled; its nine `diskutil list physical` attempts timed out. Run 4185 at `25989cf0eb7205f30ac0bb44eb279aa3b463f12c` proved the whole writable 64-GiB target as IOMedia `disk2`; it measured approximately 14 seconds for the final native process listing and 33 seconds for IOMedia. Both Apple disk jobs were running; DiskManagement's endpoint was still inactive. The former eight-second observer allowance was shorter than observed native startup, so its killed sample did not establish an IPC wait point. A missing target is ruled out for that run; service initialization, IPC or resource delays remain unresolved.
