Changelog (fork vs upstream)

Upstream reference: Rico / GeneticArtifact (last Thunderstore release noted there: 4.5.3). This package keeps the same core idea—Artifact of Genetics and per-monster gene multipliers (health, move speed, attack speed, damage)—but adds a research DDA path on top.

4.5.12 (this fork)

Changed

• SGD decision / virtual power: extended decision driver and runtime state; item-aware build-power estimation (SgdBuildPowerItemModel) and refined virtual-power sampling for axis attribution (supports telemetry and diagnostics).
• Telemetry schema v7: telemetry_schema_version = 7 with challenge provenance (h3_challenge_source), virtual-challenge semantics (h3_vc_semantics), dda_decision_step aliases, and per-axis H3 quality counters on dda_sample.
• Runtime telemetry: TelemetryDifficultySnapshot records challenge provenance for SGD / GA / FLS; H3AxisDecisionState tracks cumulative per-axis pair / nonzero / variance statistics for diagnostics.
• Research tooling (repo only): PostHog export scripts moved to tools/export_data_scripts, analysis and hypothesis charts to tools/analyze_data_scripts; H1–H4 analysis reports H3 correlation “NA” reasons in CSV/summary.
• Docs / build: integration and debug tooling notes updated; MSBuild deploy hook points at tools/export_data_scripts/InstallToRor2.ps1.

Notes

• Follow-up to 4.5.11 (schema v6 decision steps): this release is mainly richer H3 telemetry metadata and offline tooling layout; gameplay behavior is unchanged unless you rely on new event fields in your pipeline.

4.5.11 (this fork)

Changed

• Added H3 decision-step instrumentation for all modes (SGD, GA, FLS) with explicit h3_is_decision_step, step index/reason/interval, and schema bump to telemetry_schema_version = 6.
• Unified axis virtual challenge mapping to ln(clamped_multiplier) and added per-axis virtual-gap epsilon flags for hp, move_speed, attack_speed, attack_damage.
• Updated H3 analysis script to consume decision-step semantics (schema >= 6), keep legacy fallback for schema 5, and report new axis metrics (sign-match, response gain, per-axis gap/epsilon coverage).

4.5.10 (this fork)

Changed

• H3 virtual power/challenge now uses axis-aware schema (hp, move_speed, attack_speed, attack_damage) instead of relying on a single total-only path.
• Added item-aware build power estimation from inventory (ItemCatalog/ItemDef.tags + known-item whitelist) to improve axis attribution for SGD DDA telemetry and diagnostics.
• Telemetry schema updated to v5 with new H3 axis fields and h3_axis_schema=vp_vc_4_axes_v1; legacy total fields are retained for transition compatibility.

4.5.4 (this fork)

Added (vs Rico 4.5.3)

• SGD DDA pipeline (SgdEngine/): Sensors → decision (stochastic gradient–style update) → actuators that still drive the same GeneStat / RecalculateStats hooks as the genetic engine.
• Runtime algorithm selection (DdaAlgorithmState): Genetic (original GA loop), SGD, or Fixed baseline; default in source is oriented toward SGD experiments (switch via in-game cheats / rotation).
• Cheat / debug: console commands for algorithm mode, debug overlay, and parameter tweaks (dda_* family in DdaCheatManager).
• Config extensions: SGD normalization targets, per-axis floor/cap for gene stats, optional diagnostic hook toggles (SGD / actuators / telemetry / rotator), research rotator options (auto cycle algorithms and run seeds across runs).
• Optional research telemetry (PostHog; off by default, configurable—see mod config).
• Repository documentation: architecture and integration notes under Docs/SgdDda/ and RULE.md (not shipped inside the Thunderstore zip unless you add them).

Unchanged / compatibility notes

• BepInEx plugin GUID remains com.RicoValdezio.ArtifactOfGenetics for network / dependency consistency with the original mod family.
• Genetic engine (GeneticEngine/) behavior is preserved for when Genetic mode is active; SGD runs through parallel hooks/drivers.

Thunderstore icon (AI disclosure)

The package icon (icon.png) is the 256×256 neon DNA / chart motif for PainGradient: Gradient-Descent DDA. Some earlier Thunderstore revisions used a separate AI-assisted “MERCY / pain meter” graphic; uploads now use this DNA-style artwork by default.
