Changelog

All notable changes to Trainlog are documented here.

Detailed implementation chronology remains available in Git history and docs/reviews. This file summarizes the current unreleased product baseline.

Unreleased

Added

native Kotlin/Compose Android capture client;
Android local exercise, session, continuous-activity, and body persistence;
C17/ncursesw desktop TUI with direct session entry and durable SQLite history;
profile-aware exercise model using recording mode, tracking mode, and supplemental fields;
continuous activity persistence without synthetic sets;
variable repetition-set input including 5x10, explicit lists, and pyramid shorthand such as 4..10..4;
persisted desktop session editing and exercise removal;
Android current-session draft exercise removal;
body-observation history, editing, graphs, and normalized overlays;
exercise performance history;
direct physical Android USB/MTP discovery with libudev/libmtp;
direct MTP read/write/list/delete support without filesystem mounts;
Android full mobile snapshot export;
strict idempotent desktop mobile importer;
PC canonical exercise-catalog publication to Android;
automatic Android snapshot maintenance;
Android Synchroniser maintenant request flow;
shared C bidirectional synchronization engine;
trainlog-syncd user-session synchronization agent;
request/receipt synchronization protocol;
stable sy_<uuid-v4> synchronization identities;
structured synchronization history with selectable TUI list/detail views.

Changed

desktop SQLite schema evolved to v5;
schema v5 permits targetless set-session rows for actual-only mobile data;
heterogeneous performed sets are preserved without inventing a uniform target;
Android/desktop synchronization uses dedicated versioned artifacts instead of modifying frozen Trainlog JSON v1;
PC and TUI synchronization paths now share one engine;
Android PC-created artifact access uses a persistent SAF grant for Download/Trainlog;
the Android data package is no longer accidentally hidden by a broad repository data/ ignore rule;
user-facing session history timestamps use DD/MM/YYYY HH:MM while canonical storage remains RFC3339.

Fixed

stale schema-v4 importer call after desktop schema v5 migration;
stale schema-v4 guard in the PC catalog exporter;
missing sy prefix support in the UUID creator;
synchronization failures that previously surfaced only as error=unknown;
Android folder-selection UX so a wrong SAF folder can be changed without clearing application data;
libmtp terminal output leaking into ncurses rendering.

Measured max v1

Added:

explicit measured-max derivation from max_test sessions only;
newest successful measured result and same-mode historical record;
dedicated TUI measured-max history and graph;
external working-load calculations at 60/70/80/90%;
selectable 0.5/1/2.5/5.0 kg working-load rounding;
direction-aware assistance measured-max semantics;
