Changelog

v1.1.23-beta.1 PUBLIC BRANCH - Two-Deck Mobile Workstation Header, Custom Subwoofer SVG/PNG Emblem & CAD Beta Lockout: Re-architected the top header into a responsive two-deck layout with a 5-column utility bar so controls never wrap or clip on mobile screens; embedded an inline SVG subwoofer enclosure badge with dynamic 512x512 iOS Apple-Touch PNG generation and OpenGraph link metadata; and placed the 3D CAD Blueprint module under a Closed Beta roadmap lock.
v1.1.22-beta.1 PUBLIC BRANCH - Edge Physics Decoupling: Stripped proprietary client-side acoustic and KCL equations from the public frontend shell and routed state evaluation through debounced `/api/calculate` Cloudflare Worker edge requests while preserving local 60 FPS Frequency Probe scrubbing.
v1.1.22 PRODUCTION - Dark Typology Selection Modal & 10/12/18 Driver Expansion: Replaced native iOS typology picker with a custom dark-slate Enclosure Typology Modal ordered by acoustic progression (Sealed -> Bass-Reflex Ported -> 4th Order Bandpass -> 6th Order Series -> 6th Order Parallel -> ABC / 6th Order Bass-Reflex); and added 16 additional 10", 12", and 18" subwoofer profiles across Sundown, Resilient Sounds, Deaf Bonce, Stereo Integrity, DC Audio, DD Audio, and B2 Audio.
v1.1.21 PRODUCTION - Driver Database Expansion: Integrated 8 high-output subwoofer profiles with verified T/S parameters, including Sundown Zv6 15, Sundown U-15 v.2, Resilient Sounds Platinum 15, Deaf Bonce DB-SA305 15, Stereo Integrity SQL-15, DC Audio Level 4 15, DD Audio 715, and B2 Audio Rage 15 V3.
v1.1.20 PRODUCTION - State Restoration Sync, Config Export Sanitization & Container Alignment: Routed JSON Save/Load through sanitized workspace state helpers so personal operator emails and admin keys are never exported; synchronized cascading port UIs and manual volume locks when loading Admin Report builds; suppressed preset T/S drift warnings when the Raw T/S drawer is collapsed; prevented Sealed mode from unhiding the Port Velocity chart on driver change; and unified all modular panels inside `#modularWorkspace`.
v1.1.19 PRODUCTION - Automatic T/S Parameter Error Checking, Unit-Trap Detection & 1-Click Auto-Reconciler: Added real-time physical consistency verification across all 12 Thiele/Small parameters (checking Qts parallel damping, Helmholtz Mms/Vas/Sd/Fs suspension compliance, and BL/Re/Qes motor force laws); added automatic detection for ft³-vs-Liters Vas and in²-vs-cm² Sd entry mistakes; fixed cold Qts overwrite when editing Qts manually; and added a 1-click Auto-Reconcile solver.
v1.1.18 PRODUCTION - High-Contrast Onboarding UI, Custom Green EULA Checkboxes, Feedback Telemetry Reporter & Manual T/S Fix: Upgraded body text contrast across all onboarding steps; engineered custom high-visibility green EULA checkboxes with expanded touch hit-boxes; added top-right Feedback & Term-LAB Telemetry Reporter with 1-click Build Loader in the Admin Console; and fixed Manual T/S selection so the parameter grid auto-expands without wiping active curves.
v1.1.17 PRODUCTION - Pre-Release UI Framing, Admin Cohort Console & Instant Self-Reset: Added explicit Pre-Release Telemetry UI framing to the EULA and System Explainer; integrated PIN-protected Operator Cohort Admin Console (lock/unlock/remove seats) inside the Changelog modal; fixed header action button contrast; and enabled instant Gatekeeper re-launch when removing the active operator session.
v1.1.16 PRODUCTION - Mobile Keyboard Viewport Fix & 50-Seat Beta Cohort Cap: Top-pinned the Beta Gatekeeper modal and moved the Operator Email input and submit button to the top of Step 1 so the iOS on-screen keyboard never covers the login controls; and added a 50-operator beta seat cap (ARAIMENTO_MAX_BETA_SEATS = 50) with live seat counter and existing-operator pass-through.
v1.1.15 PRODUCTION - Integrated 4-Stage Beta Gatekeeper, Scroll-Locked EULA, System Explainer & Cloudflare KV Sync Hooks: Added non-bypassable 4-step operator onboarding flow (Email/KV Cloud Workspace Login -> Scroll-Locked EULA & IP/Hardware Liability Waiver -> Build Changelog -> System Physics Explainer); wired Cloudflare KV state persistence hooks (/api/auth and /api/sync with local sandbox fallback); and added top-bar GUIDE and CLOUD sync controls.
v1.1.14 PRODUCTION - Added Inline Frequency Probe Slider to Acoustic Truth Panel: Mounted a persistent, two-way synchronized Frequency Slider directly beneath the Power slider inside Acoustic Truth with live In-Vehicle and Half-Space SPL telemetry, eliminating the need to scroll to the bottom Acoustic Probe panel to sweep frequencies.
v1.1.13 PRODUCTION - Live Frequency-Tracked Yield & Cabin Wall Corner-Frequency Coupling: Linked Acoustic Truth Half-Space and In-Vehicle Effective Woofer Yield readouts directly to the active Frequency Slider position alongside a Peak Ceiling reference; and coupled Vehicle Class + Wall Placement (Standard Cargo vs. C-Pillar vs. B-Pillar) cabin corner frequency shifts against In-Box Fs so large cabins accentuate the mid-passband saddle while smaller/walled cabins fill it in below upper tuning.
v1.1.12 PRODUCTION - 6th-Order Series Bandpass Calibration & Saddle Damping Fix: Removed legacy -5.0 dB hardcoded attenuation pad that artificially depressed 6th-Order Series SPL and Effective Woofer Yield; softened over-damped inter-chamber compliance shunts (33 Hz / 50 Hz dips) to match real-world in-cabin passband smoothness; and wired dynamic boundary-layer port drag (tuning_dyn3, fb2_dyn3) directly into the 6th-Order Series transfer function and velocity loops.
v1.1.11 PRODUCTION - Aperiodic Bi-Chamber (ABC) Upper-Port 180° Phase-Inversion Null: Modeled the real-world destructive acoustic phase cancellation cliff 2 to 3 Hz above the upper port tuning (EXT Fb), where the external port air column flips 180° out of phase with the direct radiating cones and drops output by 24–28 dB into a deep upper-frequency acoustic choke.
v1.1.10 PRODUCTION - Aperiodic Bi-Chamber (ABC) Passband & Direct Cone Summation Fix: Isolated the inter-port handoff dip strictly to the port labyrinth so direct cone radiation around In-Box Fs (41 Hz) holds a flat, full mid-bass shelf; tamed the upper port resonance so it forms a smooth upper shoulder instead of spiking; and anchored the step-up air-column amplification on the lower Fb tuning.
v1.1.9 PRODUCTION - Aperiodic Bi-Chamber (ABC) Pneumatic Step-Up & Low-Fb Helmholtz Amplification Fix: Replaced unity-clamped band-reject resonator terms and sub-Fs cone attenuation with a true dual-Helmholtz pressure transfer function coupled to a 2-stage pneumatic step-up column transformer (scaling lower Fb1 cabin coupling by the External-to-Internal port area expansion ratio), preserved `port_lowpass` for velocity calculations, and shifted the acoustic unloading knee below Fb1 to eliminate fundamental tuning attenuation.
v1.1.8 PRODUCTION - Phase 6 Alignment Siloing Complete (ABC Bimodal Resonator Fix & 6th-Order Series Dynamic Lock): Replaced multiplicative low-pass port cascade in Aperiodic Bi-Chamber (ABC) with a true bimodal parallel-pole Helmholtz resonator summation so internal and external port resonances do not artificially attenuate each other when Fb2 > Fb1; updated ABC Chamber 1 telemetry labels to CH 1 PRIMARY NET and INT Fb; and completed dynamic boundary-drag and spider-shift integration in 6th-Order Series Bandpass.
v1.1.7 PRODUCTION - Phase 5 Alignment Siloing (Aperiodic Bi-Chamber / ABC Overhaul): Renamed typology 6 to Aperiodic Bi-Chamber (ABC); replaced shared Series 6th-order impedance approximation with a true 2-stage KCL acoustic ladder network (Chamber 1 compliance coupled through Internal Port 1 into Chamber 2 resonator and External Port 2); decoupled direct cone radiation from the port-labyrinth high-frequency mass choke; wired dynamic spider stiffening (Fs_dyn) and port boundary drag into ABC telemetry and transfer function; and added internal coupler port rendering to the 2D CAD Top Section view.
v1.1.6 PRODUCTION - Phase 4 Alignment Siloing (Parallel 6th-Order Bandpass Isolation): Removed Series inter-chamber port mass-coupling bleed from Parallel 6th-Order so both externally exhausting ports evaluate at their true independent Helmholtz tunings; wired dynamic spider stiffening (Fs_dyn) and turbulent boundary-layer drag (Fb1_dyn, Fb2_dyn) into the Parallel 6th-Order transfer function and Acoustic Truth telemetry; enabled Net/Woofer display; and linked Fb1/Fb2 to global Tone Lab and phase locks.
v1.1.5 PRODUCTION - Added Dynamic Frequency Shift Telemetry & Physics to Bass-Reflex (Ported): Integrated turbulent boundary-layer port drag (Dynamic Shifted Fb) and progressive suspension stiffening (Static vs. Dynamic In-Box Fs) into the Ported transfer function and Acoustic Truth readout.
v1.1.4 PRODUCTION - Integrated Dual Effective Woofer Yield & Acoustic Leverage Engine: Added real-time Half-Space (pure enclosure) and In-Vehicle (cabin-coupled) effective subwoofer yield and leverage multipliers to Acoustic Truth and the frequency-specific Acoustic Probe, dynamically tracking efficiency gains and power/thermal/turbulence compression against an uncompressed 1:1 sealed baseline.
v1.1.3 PRODUCTION - Phase 3 Alignment Siloing (4th-Order Bandpass & Pneumatic Compression Overhaul): Fixed Acoustic Truth readout bug where Qtc was displayed in place of Rear Sealed Fcb; integrated non-linear adiabatic rear-chamber gas stiffening and progressive spider shift into 4th-Order Fcb and dynamic passband efficiency; added Dynamic Shifted Fcb, Dynamic Shifted Fb2, Rear Compliance Ratio (alpha), and 1st Pipe Resonance tracking to 4th-Order telemetry; and linked Fcb/Fb2 to the Live HUD Ribbon and Tone Generator lock targets.
v1.1.2 PRODUCTION - Phase 2 Alignment Siloing (Acoustic Suspension / Sealed Overhaul): Restored Acoustic Probe and Target Power controls in Sealed mode while cleanly hiding the Port Velocity panel; corrected KCL sealed air-spring absorption conductance from static Fs to frequency-proportional loss tangent (Qab = 7) to eliminate artificial subsonic excursion creep below 20 Hz; added System Resonance (Fc), Dynamic Shifted Fc, and Compliance Ratio (alpha) to Acoustic Truth and the live HUD ribbon; and mapped Sealed DSP alignment classifications directly to textbook Qtc damping thresholds.
v1.1.1 PRODUCTION - Phase 1 Alignment Siloing (Ported, Sealed & 4th-Order Excursion/Safety Isolation): Defaulted startup state to Bass-Reflex (Ported) baseline; eliminated double subsonic excursion unloading in Ported mode so KCL mechanical impedance governs sub-Fb excursion natively; isolated 4th-Order sealed rear chamber from ported subsonic unloading; repaired inverted passband excursion scanner on 4th-Order Bandpass; added active Sealed Xmech limiter and passband excursion warnings; and synchronized static/dynamic version headers.
v1.1.0 PRODUCTION - Milestone 1.1 Workstation Overhaul: Deployed sticky 5-mode Mobile Workstation HUD (DESIGN, GRAPHS, CAD/CUTS, LAB/ELEC, ALL) with persistent real-time acoustic telemetry ribbon. Added deterministic 2D/Isometric Parametric Blueprint Renderer and automated Table-Saw Cut-Sheet Generator. Integrated coupled Lithium Bank & Alternator Reserve analyzer and native Web Audio API Tone & Sweep Lab.
v1.0.27 PRODUCTION - Executed 8-point physics and state synchronization overhaul: replaced lagged 6th-Order cone-pump excursion lookup with a synchronous real-time KCL electromechanical evaluation to eliminate 1-frame velocity lag; restored 1st Pipe Resonance tracking across all 6th-Order and ABC bandpass typologies; fixed logarithmic-to-wattage unit mismatch in `lastSafePower` and `syncMiniPower` when triggering the Xmech brick-wall limiter; unified multi-driver `series_parallel` and `parallel_series` impedance scaling across electrical, wiring, and KCL solvers; added automatic nominal diameter and cutout scaling on driver preset load; guarded manual T/S entry against NaN propagation; and added `.grid-4` layout support.
