RC4.5.9 publication ledger¶

Historical record. This preserves the source, tests and limitations recorded at the time; it is not current setup guidance. See the documentation index.

Published release identity¶

• VIIPERRC4.5.9: Release Candidate 4.5.9 Hotfix — Faster Feedback, Same Detail.
• Published 2026-09-12T16:46:22Z, release ID 387633008, as an unsigned named-RC prerelease under the existing draft-first policy.
• Source: 93ce8899a66ab3702824b879e1d7a8f378386db4, pushed to main before tagging. Annotated tag object: 37af38f542688cae4d31e99f959b9bc7c6cc8623.
• Application, MSI and Burn version: 5.0.5.9; display/portable identity: VIIPERRC4.5.9. Both changelogs and the installer upgrade fixture were updated.
• VIIPER remains the complete published 0.1.4-rc4.5.6, source 02d93e403ffde7ad24c1b373c01c6eb04ce02f2e, binary SHA-256 89808A41610997A6DAD0807579B816C18B34C039E03E96FDC8FD2BD68434FFBB.
• DS4Updater remains 2.0.6, source 173c27b4eb31f369280abce173e31264b317231e; no broker/updater release needed.

Validation before publication¶

• The first local full run was held on an allocation assertion. The same-workload investigation, actual-object positive control and unchanged strict-zero gate are documented in the allocation ledger. No production GC/JIT/transport change resulted from that investigation.
• Final rebuilt local suite: 5,539 passed, zero failed, 11 existing gated skips. Allocation assertions stayed enabled; an intentional report-copy control proves the exact-zero assertion still rejects real allocations.
• Exact-source main CI 34705080033 passed the same 5,539 tests, startup/ownership checks, complete packaging, offline layout, MSI install/repair/uninstall and published-RC4.5.5 upgrade with profile preservation. These installation tests ran on the disposable hosted Windows runner, not on the user's installation.
• Tagged draft build 34705645228 produced all 13 workflow-owned assets. No private candidate was substituted, and no asset was overwritten. Actions uploader, GitHub size/digests, source commit, corresponding-source ZIP comments, checksums and receipt were verified.
• Source archive version/changelog files were independently compared with the final Git blobs; only Git's pure CRLF-to-LF text export normalization was allowed.
• Complete portable checks verified 553 files, 297 dependency assets, 23 language satellites, 507 immutable byte hashes, 18 text assets, .NET/WindowsDesktop 8.0.30, both broker aliases, Xbox persona and notices.
• Offline installer extraction verified 8 embedded Burn payloads, 551 MSI files, and exact byte equality of all 549 shared payloads with the ZIP. The bundle/MSI/helpers were not executed on the user's machine.

Actual updater and publication checks¶

The immutable updater DLL SHA-256 is 04B8E564F25CBEC14C65192D9E10408C01218B95B31EAFD1F0511B799E7873F1. Its real filesystem transaction applied the final ZIP to a fresh synthetic RC4.5.8 folder, verified all 553 files, preserved eight user-data sentinels, removed an obsolete owned file and left no staging transaction behind. No real profiles, keys, installations or controller apps were modified.

The actual draft receipt/API passed four checks, including rejecting an update to an unpublished draft. After publication, the unchanged updater passed 21 actual-receipt policy checks: earlier RCs advance, equal/newer versions do not, the receipt resolves 5.0.5.9, drafts and altered receipts are rejected, and binary downgrade protection remains enforced. The portable bootstrap obtains this published updater; no stale updater executable was added to the ZIP.

Published metadata and all 13 local/downloaded asset hashes match the verified draft. The published-event audit 34706247688 passed against the exact tagged source and successful draft-build receipt. It downloaded and checked the published bytes without rebuilding or replacing any asset; the release-build job was correctly skipped for this event.

Exact downloadable bytes¶

Application DLL SHA-256: FBBD5DA81B04060B783C35E2FCA1D5950218EC2A9442512E64656C9D3D1D76FA. Application EXE SHA-256: 54DC1D89C04535363C23FD3A275D4120EBE86DA2BCA7EED96AE0FFAF35C10CAA.

Local assets and offline extraction evidence are under Desktop DS4Windows-RC4.5.9-Release; updater proofs and test logs are under isolated_results/rc459-publication/.

Feedback acceptance boundary¶

The live cadence evidence covers body-rumble transition order and host-side physical-writer submission timing. The faster ordered path also carries adaptive-trigger commands, whose full payloads, changes and stops have automated preservation coverage. In-game adaptive-trigger feel, GTA rapid-fire smoothness, radio arrival and actuator latency are not confirmed by these tests. Gameplay confirmation for issue #81 remains necessary; no issue was closed as part of this publication. PCM samples/gain, local Trigger Lab priority and Nintendo rumble tuning were not changed by this release.
