2026-08-07 - Stage Collision and Reaction Documentation Corrections

Corrected

2026-08-07 - Random Functions and Gameplay Impact

Added

  • Added an evidence-scoped cookbook covering SC6's seeded Lux battle RNG, nondeterministic audio-only random paths, known gameplay consumers, and replay/rollback-safe investigation and modding rules.

2026-08-07 - HorseMod Rollback Cookbook Cross-Check

Changed

  • Reconciled the rollback investigation with the current HorseMod production-path implementation: Steam P2P beta-v2 default/UDP compatibility routing, the 128-state snapshot handle model, current native snapshot coverage, and the single remaining PresentationDispatch manifest blocker.
  • Added a three-part end-of-cookbook status section that distinguishes locally implemented/self-tested components from pending evidence and the blockers to artifact-bound live two-process SC6 acceptance. Replay, parser, oracle, and local Gekko results are explicitly not represented as live gameplay proof.

2026-08-02 - SC6 MOT-to-Blender Export Cookbook

Added

  • Added a Ghidra-backed cookbook for exporting SC6 HgMotion clips to Blender, including fidelity targets, matching-rig extraction, Huffman/selector decoder requirements, matrix normalization, a Blender Action bake script, runtime capture guidance, validation, and current decoder coverage.

Corrected

  • Corrected the .mot outer bank layout to include the reserved dword and +0x08 offset table, and documented repeated-offset aliases and the absence of a guaranteed count + 1 end sentinel.

2026-07-10 - Rollback Production-Path Evidence

Changed

  • Updated the rollback investigation with the disabled-by-default Horse UDP/Gekko production architecture, authenticated protocol-v2 envelope, three distinct hash domains, 128-state handle ring, game-thread ownership rules, and fail-closed lifecycle boundaries.
  • Corrected native input-cache identity: stock opcode 0 falls back to the current nLastFrameId for a negative frame argument, uses an absolute frame for its bitmap, and places only the low nibble on the wire.
  • Added recovered HgCpu physics (0xD80), timer-node (0x2F0), timer-config (0x12C), motion bounds-grid (0x44C), and canonical WorldModePump (0x40) layouts, including the timer reader's live-identity preservation semantics.
  • Documented the proven HgCpu coverage boundary, eight-byte cursor range, breakable wall/barrier scalar state, confirmation-time audio/VFX ledger, and wind emitter RNG/timer progression required during hidden resimulation.
  • Recorded 22 passing standalone rollback self-tests, 11141/11141 replay input records, and strict replay run 20260710-021112-seek with four of four 600-frame watch cases and zero state mismatches, while explicitly retaining ten PendingEvidence gameplay gates and making no live two-process acceptance claim.

2026-07-07 - Ranked Matchmaking Player Guide

Added

  • Added a cookbook player guide that explains SC6 ranked matchmaking in plain language: rank-range tickets, retry-based range expansion, previous-result buckets, and why the recovered search path does not directly blacklist the last opponent by identity.

2026-07-06 - Online Matchmaking Internals

Added

  • Added a dedicated SC6 online matchmaking internals article covering ULuxorSessionHub player-room and ranked-session create/find helpers, FLuxorPlayerMatchSessionSetting and FLuxorRankMatchSessionSetting layouts, UE session metadata keys, and the ranked previous-result filter.
  • Documented the difference between ranked repeated-result filtering (nPrevBattleResult -> CUSTOMSEARCHINT7) and ULuxorMatchData.nRematchType, which is post-match/rematch UI metadata rather than a session-search key.

Changed

  • Clarified that the verified native ranked search path does not avoid the same opponent by identity: FindLuxorRankSession has no opponent-ID query key, HandleLuxorFindSessionResult forwards all returned results, and InvokeFindSessionCallback only marshals the result array to Blueprint.
  • Expanded the ranked PrevBattleResult analysis with the BP_LuxFightRequest.CreateMatchSetting producer logic: first ranked searches use bucket 1 for nonzero winning streak and bucket 2 for zero winning-streak/not-winning state, while later retries send 0 and relax the native CUSTOMSEARCHINT7 filter.
  • Added the profile/style history helpers that back the previous-result bucket: reset clears dwHistoryFlags, win updates set bit 0, and non-win updates clear bit 0.
  • Added a note tying the Ver. 1.30 official patch notes to the recovered native behavior: the patch notes mention removing Language/Area filters, setting a default 4+ bar connection filter, and removing ranked rematch-option limits, but not same-opponent avoidance.
  • Linked the new matchmaking page from the SC6 internals navigation, SC6 index, symbol index, and the existing online/netplay article.

2026-07-03 - PlayFab Party Practical Latency Estimates

Changed

  • Added cautious Norway-to-America and Norway-to-Japan PlayFab Party relay estimates, including Azure Norway East inter-region P50 sanity checks, realistic median-RTT improvement ranges, and guidance to judge routes by p95/p99 jitter, loss, stalls, late inputs, and rollback pressure instead of average ping alone.
  • Documented the relay-only baseline tradeoff: safer peer-IP privacy and a more controlled test path, but potentially worse latency than a good direct route.

2026-07-03 - PlayFab Party Route-Quality Clarification

Changed

  • Clarified the PlayFab Party relay cookbook to distinguish unavoidable physical propagation latency from avoidable routing overhead, ISP hairpinning, congestion, jitter, loss, NAT trouble, and route instability.
  • Made the Party framing less dismissive by explaining how QoS measurement, selected Azure regions/backbone paths, transparent relay behavior, session policy, and optional direct-peer mode could plausibly improve bad routes while preserving the requirement to measure against good direct and Steam Datagram Relay paths.

2026-07-03 - PlayFab Party Netcode Relay Revision

Changed

  • Reframed the netcode relay cookbook around PlayFab/PlayFab Party as the lead managed transport and control-plane candidate, covering QoS measurement, region selection, transparent cloud relay, optional direct peer policy, and TURN-like fallback behavior.
  • Demoted raw Azure VM/VMSS relay infrastructure to a lower-level custom data-plane fallback, while preserving the caveats that relays cannot beat the speed-of-light floor, cannot outperform good direct peering by default, and still require native transport ownership.
  • Updated the Cookbook index and MkDocs navigation label to match the PlayFab-focused framing.

2026-07-03 - Azure-Backed Netcode Relay Investigation

Added

  • Added a documentation-only cookbook investigation for whether an Azure-backed UDP relay could improve America-Europe SC6 online route quality, covering speed-of-light limits, why relays cannot beat good direct peering, stock SC6/Steam transport ownership risks, Azure VM/container relay candidates, PlayFab/Party and signaling options, Azure Relay/Web PubSub limitations, TURN-like fallback behavior, telemetry, prototype phases, privacy/ToS boundaries, and decision criteria.

Changed

  • Linked the Azure relay investigation from the Cookbook index and MkDocs navigation.

2026-07-03 - Single-Machine Rollback Testing Cookbook

Added

  • Added a practical cookbook page for automated SC6 online/rollback netcode testing on one machine, covering in-process virtual peers, baseline-vs-faulted harnesses, loopback shims, two local game processes, VM/sandbox isolation, Windows network emulation, Steam/relay limitations, replay/log-driven tests, parser/comparator CI, fault injection, instrumentation, artifacts, pass/fail gates, and what local tests cannot prove.

Changed

  • Linked the new rollback testing cookbook from the Cookbook index and MkDocs navigation.

2026-07-01 - Ghidra Validation Pass

Changed

  • Replaced stale FUN_* references for character-select menu builders, pause-delegate metadata, camera pose writers, weapon-tip event dispatch, and move-bank event-tree setup with confirmed Ghidra symbol names.
  • Added the reflected FLuxBattleOptionParam layout and clarified that its InputDelayFrame property does not drive the live FrameInputLog+0x390 online-input delay path.
  • Clarified that FLuxMoveCommandPlayer is represented as a sparse Ghidra struct applied at g_LuxMoveVM_CommandPlayerArray.

2026-07-01 - Rollback Testing and Diagnostics Expansion

Added

  • Expanded the rollback netcode cookbook with a local automated test topology, harness components, config matrix, scripted/headless run tiers, reproducible artifacts, pass/fail gates, and the limits of local testing versus real online play.
  • Added player-facing jitter-first connection diagnostics guidance covering rolling RTT, jitter, loss, stalls, rollback pressure, cautious likely-cause warnings, honest UI wording, and privacy-safe telemetry.

2026-06-28 - DotVanisher Cookbook Recipe

Added

  • Added a standalone DotVanisher cookbook article explaining the host spectator timeout issue, the HandleHostTickWatchEventQueues detour, binary/prologue guard checks, pending-watch epoch tracking, 90-second grace behavior, packaging layout, verification logs, and troubleshooting notes.
  • Linked the DotVanisher recipe from the Cookbook index and MkDocs navigation.

2026-06-26 - Native Hook Documentation Cleanup

Changed

  • Removed the legacy scripting/reflection API pages from the docs navigation and site tree.
  • Reworked SC6 and cookbook cross-links so runtime guidance points at native DLL hooks, direct _Impl calls, runtime probes, and native ProcessEvent diagnostics instead of scripting API helpers.
  • Updated the README, homepage, glossary, cookbook template, and MkDocs metadata to describe the project as native modding and reverse-engineering documentation.

2026-06-26 - Practical Cookbook and Runtime Hooking Pass

Added

  • Expanded SC6-specific runtime-hooking notes for live object discovery, reflected helper boundaries, ProcessEvent filtering, map/menu transition invalidation, and native-boundary escalation.
  • Expanded the wholly-new custom-stage cookbook into a fuller implementation checklist covering stage-code selection, pak layout, load-path routing, picker integration, metadata/collision validation, troubleshooting, and online desync risks.
  • Added practical CPU/training-dummy guidance for scripted SubVM drills, training-mode UFunction usage, native frame-input overrides, and runtime verification.
  • Added practical audio-modding guidance for ACB/cue-sheet routing, weapon SE, voice replacement, costume-part SE relevance, stage foley, muting/ducking, and fast-forward/rollback side-effect gating.

Related commit: 7868995

2026-06-26 - Stage Collision Replacement Notes

Added

  • Expanded the stage replacement cookbook with practical collision-layer guidance for visual BodySetup collision, breakable wall/barrier actors, structured round-restore storage, and paired J_StgHitChkData raw hit-data blobs. The newer correction above supersedes the former barrier-array interpretation.
  • Added a community exploration workflow for testing wall collision changes, donor hit-data swaps, and possible extra breakable wall experiments without implying that actor placement alone creates deterministic wall cells.

2026-06-25 - Rollback Netcode Feasibility Investigation

Added

  • Added a Cookbook investigation page for rollback netcode feasibility, grounded in Ghidra MCP evidence from SC6's online input, replay, simulation, RNG, and snapshot paths.
  • Added a practical minimal prototype plan for validating deterministic restore/resimulation locally under E:/myMods.
  • Added a testing methodology and fault-injection plan for proving or falsifying rollback feasibility, including instrumentation, pass/fail criteria, and offline HorseMod versus native online-transport test boundaries.

Changed

  • Linked the new rollback investigation from the Cookbook navigation and index.
  • Documented why InputDelay+0x390 is not the live online delay control, where delay/catch-up is actually enforced, and why native hooks are required beyond a scripting/reflection-only control layer.

2026-06-25 - Home Changelog and Hitbox Documentation Pass

Added

  • Added this Recent Changes page under the Home tab and linked it from the landing page.
  • Added repository instructions that make changelog maintenance part of the commit workflow.
  • Added KHit overlay guidance for reading native world buffers instead of reconstructing collision geometry from render-pose helpers.

  • Converted Recent Changes from a raw commit table into this curated changelog format, grouped by documentation area and date range.
  • Reworked the hitbox documentation around active attack cells, opponent cell copies, active-frame phase bytes, and damage / reaction gates.
  • Clarified that chara+0x44048 is the defender-side opponent active-cell copy and chara+0x44058 is the chara's own current attack cell.
  • Expanded hurtbox mask notes for opcode 0x13AC, including the inverted disable-mask behavior.
  • Added practical overlay predicates for attack visibility, active-frame state, Lane 2 alternate masks, and classifier-addressable hurtbox slots.
  • Refined selection menu coverage and linked it into the SC6 docs navigation.
  • Expanded the reference glossary with more cross-cutting SC6 terms.
  • Documented replay and stage revisions that connect launcher setup, battle settings, on-disk files, and stage system internals.
