Define the evidence package for one release
Start with a concrete release and list the records needed to reproduce or support it: source revision, build configuration, final artifact, receipt, native signature result, test summary and private diagnostic mappings. Include the exact output that customers receive rather than only an intermediate build directory.
Assign a stable release identifier and store the artifact hash in the surrounding CI record. Avoid using only a mutable filename such as latest.zip. The identifier should let an engineer find the correct receipt, symbols and test evidence without guessing which later build replaced the original upload.
Separate access classes deliberately
Public downloads, internal release evidence, crash symbols and authentication keys have different audiences. Keep them in separate controlled stores or namespaces with explicit access rules. A manifest can include paths that reveal internal structure, so review it before deciding whether it belongs in a public release.
HMAC keys should remain in the secret-management path, not next to downloadable receipts. If key rotation is planned, retain a mapping from historical release identifiers to the appropriate verification key reference. Do not assume a new key can authenticate an old record without preserving the original trust context.
Choose retention around actual obligations
Agree internally how long each class should remain available and who owns deletion or preservation decisions. Consider update support, crash investigation, rollback and the need to reproduce public benchmark observations. This guide does not prescribe a legal retention period; that depends on your organization’s applicable requirements.
Record tool and dependency revisions for experiments as well as production releases. Historical analyzer results should remain attached to the code that produced them. A future rerun with updated tools is new evidence and should not overwrite the original record or silently change its stated environment.
Rehearse retrieval and failure handling
Periodically retrieve an older authorized artifact, verify its receipt and locate its matching private diagnostics. Test a deliberate mismatch on a copy to confirm the gate rejects changes. For native releases, check the relevant signature or installation path when required rather than relying only on file hashes.
Document what happens if a store is unavailable, a key is retired or a diagnostic bundle is missing. A release-evidence process is useful only if the team can use it during an incident or support request. Treat a successful retrieval exercise as an observed result; keep the 2027 schedule itself clearly labeled as planned work.
Practical checklist
- Connect final artifacts and receipts with stable identifiers.
- Separate public, internal and secret data.
- Assign retention and deletion owners.
- Rehearse retrieval, verification and rollback.
