password/decrypt_command, or mark generation as failed by setting
diagnostic_logd, password, and decrypt_command to null; do not report plain-text

resulting production output.

Do not claim a valid encrypted artifact for the placeholder .logd.
This report supplies diagnostic_logd, a password, and a decrypt command, but diagnostic/build-00000000.logd contains plain-text stub content rather than an encrypted archive. Replace it with the actual generated artifact, or mark the report as a logd-generation failure with diagnostic_logd: null and no password/decrypt command.

Regenerate the report metadata from the current builder.
The current build.py contract describes the encrypted .logd as the required diagnostic content and the JSON as metadata, but this checked-in pr_note still uses the older “include this JSON diagnostic report” wording. If this is a golden artifact, regenerate it through the current build path so the fixture cannot drift from production output.

Replace the stub with a valid .logd fixture.
build.py treats this path as the output of encryptly pack, while diagnostic/build-00000000.json advertises it as decryptable. A plain-text placeholder cannot satisfy that artifact contract; commit the generated encrypted artifact or update the JSON to report that logd creation failed.

Assert the exact chunked decrypt command.
Checking only that the command contains the commit ID and ends with the password would allow an incorrect archive path or command structure to pass. build.py derives the multi-file target as diagnostic/build-deadbeef.logd; assert the complete contract.

Verify chunk contents, not only aggregate size.
A splitter could reorder, truncate, or replace bytes while still producing three chunks whose total size is 2,500 bytes. Preserve the input payload and assert that concatenating the generated chunks reproduces it exactly.
