Bookcicle Desktop 0.1.75 — Twain-EA

0.1.75 Twain-EA September 19, 2026

Introduces configurable minimum splash visible duration (defaulting to six seconds) and installer tile branding across macOS and Windows.

Added

Configurable minimum visible splash duration (defaulting to six seconds) ensuring branded startup visuals remain visible before workspace handoff.
Installer tile branding with custom volume icon on macOS DMG, and embedded tile icon and logo in Windows MSI and bootstrapper.

Improved

Readiness coordination holds until the minimum visible duration when the application finishes initial startup early, transitioning immediately once ready if initialization exceeds six seconds.
Splash supervisor process terminates immediately on child process crash during splash hold without trailing delay.
Non-destructive Apple Event peeking and transactional acknowledgment during splash handoff on macOS.

Included

Bookcicle Desktop 0.1.75 — Twain-EA bundles Studio UI 0.1.136.

Bookcicle Desktop 0.1.74 — Twain-EA

0.1.74 Twain-EA September 19, 2026

Introduces native startup splash launcher with length-framed lifecycle handoff, durable event recovery, and production packaging hardening.

Added

Native startup splash launcher renders branded launch visuals immediately via AppKit on macOS and Win32 GDI on Windows, eliminating initial unpainted window delays.
Length-framed socket handshake coordinates application readiness and ensures smooth splash-to-workspace visual transitions.
Durable event recovery safeguards deep links, file open requests, and launch arguments across process restarts and recovery cycles.

Improved

Decouples startup presentation from heavy GPUI runtime boot, background agent checks, and synchronous Keychain access.
Enhanced socket framing bounds and semantic child binary version resolution.

Fixed

Prevented startup delays caused by unpainted initial window presentation.
Fixed event forwarding on macOS cold start and natural second-launch instances.

Bookcicle Desktop 0.1.72 — Twain-EA

0.1.72 Twain-EA September 18, 2026

Introduces native outline synchronization with guarded section recovery, interactive Writing Coach proposal cards, durable gap tracking with proof capsule verification, and unified desktop windowing.

Added

Native outline synchronization keeps chapter structure aligned across workspaces with a guarded section recovery healer.
Live updater displays active download progress, a completed installation indicator, and a one-click restart action to apply updates.
Native authoring process acquisition tracks durable gap batches across restarts and enables signed proof capsule verification.
Unified Splash and About experience features a movable titlebar and dark-glass action pills.
CareerGR Cross-surface authoring and real-time collaboration drivers validate synchronized keystrokes, section CRUD, and conflict resolution across shared workspaces.

Improved

Writing Coach now presents friendly interactive edit proposal cards instead of raw JSON code blocks, making manuscript suggestions easy to inspect and apply.
Full-manuscript Writing Coach reviews now enforce token budget limits and filter out deleted sections.
Authorship inactivity detection decouples the 5-minute inactivity trigger from the idle countdown so full countdown intervals begin after reaching idle.
Virtual desktop switching guards prevent false macOS App Nap sleep triggers while preserving native sleep and screen lock handling.

Fixed

OurSircle Offline-to-cloud identity recovery contracts now isolate offline shell placeholders and enforce immutable root task lineage across federated accounts.
Settings window now reliably surfaces in front of active editor windows when opened from macOS application menus.
Contributor identity sync skips offline placeholders and logs structured diagnostics for missing remote profiles.
Cross-surface collaboration sync now properly reconciles remote section deletions without leaving orphan tabs.

0.1.64 Twain-EA September 9, 2026

Adds verified human sessions and carries retained authorship evidence through saved revisions, proof capsules, and their verification views.

Added
