Desktop

Implemented:

  • C17/Notcurses true-color TUI (72x20 minimum, UTF-8 prompts, resize fallback);
  • UTF-8 cell-aware scrolling training-knowledge screen, tested at the 72x20 minimum terminal;
  • SQLite schema v11, with stable ordered session_exercises.entry_id, occurrence-level equipment identity, and desktop-local custom-equipment definitions, plus occurrence-owned max_results; its v9 -> v10 migration rebuilds only performed_sets to permit explicit zero actual loads while preserving historic NULL and positive rows;
  • canonical generated body-zone taxonomy, direct primary/secondary exercise relations, stable-ID-only initial migration and descendant-aware filtering;
  • direct session entry;
  • normal desktop SETS planning followed by the table-only explicit actual-row editor; zero-row completion is rejected while MAX and continuous entries keep their separate no-set contracts;
  • persisted session detail and editing;
  • exercise removal from a session through transactional child replacement;
  • exercise catalog;
  • supplied-equipment browsing/search/detail and desktop-local custom-equipment creation/selection;
  • profile-aware set and continuous activities;
  • heterogeneous repetition sets;
  • multiple occurrences of one catalogue exercise in a session;
  • per-set actual loads with distinct external/assistance semantics;
  • body-observation creation/history/editing;
  • body graphs and normalized overlays;
  • exercise performance history;
  • direct USB/MTP device access;
  • manual Android -> PC, PC -> Android, and bidirectional synchronization;
  • structured synchronization history and detail.

Android

Implemented:

  • native Kotlin/Compose application;
  • local SQLite database v10, with non-destructive v3 -> v10 migration;
  • one durable active-session draft, Home resume and raw-form restoration;
  • explicit confirmed discard and atomic completed-save/draft-clear;
  • exercise creation;
  • stable-ID exercise rename/editing with referenced-profile protection;
  • primary/secondary body-zone selection, display, hierarchy filtering and prefix-search composition, including visible unclassified exercises;
  • inline exercise creation during session entry;
  • profile-aware session recording;
  • heterogeneous repetition-set entry;
  • exercise removal from the current session draft;
  • continuous activity recording;
  • shared equipment selection, local custom equipment creation and occurrence equipment persistence;
  • local session history/detail;
  • body measurements;
  • automatic mobile snapshot maintenance;
  • PC catalog application through a persistent SAF folder grant;
  • Android-triggered synchronization request;
  • synchronization receipt handling.

The Android catalog exposes Modifier for every existing exercise. A rename updates name and normalized_name in the original row, never creates an ID, and remains valid for completed session and active-draft references. A profile change is only accepted while the row has neither completed-session nor draft references. Same-ID catalog reconciliation updates display metadata in place. A different-ID normalized-name collision is reconciled only when recording and tracking modes match, other known invariants are compatible, and one data_fields mask contains the other. PC identity is canonical on Android; the existing desktop identity is canonical on desktop. The richer bit-mask union is retained without rewriting historical occurrence snapshots.

All Android screens use the shared compact ◆ TRAINLOG ◆ header: the Notcurses accent, muted context line, and flat touch layout reproduce the TUI plaque without literal terminal box drawing.

Training knowledge V1

The implemented read-only training-knowledge layer loads six versioned JSON catalogs as the sole authored scientific source, generates the immutable C catalog representation, and loads the same assets on Android. It has no database migration, no auto-seeding, and no synchronization artifact. The desktop database remains schema v11 and Android remains schema v10.

Desktop training_knowledge.h and Android TrainingKnowledgeCatalog expose source-linked science lookups and resolved-candidate filters. Desktop training_context.h and Android TrainlogRepository compose one real runtime exercise with its persisted zones, compatible equipment, latest explicit MAX, and bounded chronological occurrence/set history. Persisted zones remain separate from scientific mappings; missing scientific knowledge is valid.

The scientific review passed and the reviewed catalog bytes remain unchanged. The independent temporal review returned TEMPORAL_DELTA_REVIEW=PASS, with no temporal defects or repairs. It reviewed the grammar, calendar and offset bounds, fraction precision, bytewise ties, cursor aliasing and exclusivity, source capacity, snapshots, and Android/Python parity; it ran the targeted Meson and four Python temporal tests. The initial full-tranche engineering audit initially failed with stale temporal-defect documentation (BLOCKER), Android loader parity gaps (BLOCKER), omitted Meson generator inputs (BLOCKER), and a C role-only query mismatch (HIGH). One bounded repair chain resolved all four findings; independent repair verification returned FINAL_REVIEW_REPAIR_VERIFICATION=PASS and TRAINING_KNOWLEDGE_V1_ENGINEERING_REVIEW=PASS. Fresh final validation passed: strict build, 42 Meson tests, eight knowledge and four temporal Python tests, knowledge/JSON/import validators, three C17 headers, affected C knowledge and context tests under ASan/UBSan plus Python timestamp validation, normal and sanitized 12-form temporal probes, and Android 56 tests with zero failures or errors and one known missing-real-v9-fixture skip; Java 17 assembleDebug also passed. Generated C is byte-identical with SHA-256 e8c099f67eb111d61621b5d76592c049823af5508d43e73ec646f22e4c377fca; all six Android assets are byte-identical. Preservation before and after repair confirms schema v11/v10, unchanged catalog/science/temporal bytes, and unchanged real database logical SHA-256 26139cafeffbde3ec08f6ef23c5069e75afb9cd69ffffb40be5c099006fedc4d, counts, integrity, and foreign keys. TRAINING_KNOWLEDGE_V1=PASS. The temporal contract defines the settled reader behavior. No manual Android install, manual TUI visual validation or manual MTP validation is claimed for this tranche.

The desktop TUI and trainlog-syncd share trainlog_sync_run(). Its explicit a, p, and b modes perform Android -> PC only, PC -> Android only, and inbound-then-outbound respectively. Each direction reconciles equipment definitions V1 before V2 artifacts that reference them.

Each structured local sync-history run persists its selected a, p, or b direction. direction inconnue is reserved for legacy history rows whose direction was not recorded; it is never used for a current run.

On the TUI Sync page, a, p, and b directly open one confirmation for the selected direction; Enter runs that confirmed action once, while Esc cancels it without an operation (or returns when idle). r refreshes device status only, and the former s shortcut is inert. Full and compact footers use the same three directional actions, with compact labels only abbreviating the endpoints.

V2 resolves equipment by (session_id, entry_id), never by display name or catalogue identity alone. V1 files remain legacy-compatible and do not gain multi-occurrence semantics retroactively.

Body-zone relations have one direction-neutral companion and are keyed only by canonical zone IDs and exercise_id. Identical state is an idempotent skip; a successful publication records that exact state as the publisher baseline, so a later peer-only edit of a new custom exercise is accepted. Simultaneous divergence is an explicit conflict and secondary lists are never unioned. The unclassified state has no relations; orphan secondary rows are invalid. Parent groups are derived from the manifest and never serialized as exercise relations.

Supplied equipment remains generated from catalog/equipment-v1.json; its IDs are reserved. User-created definitions synchronize additively through the directional definitions V1 artifacts. Equal same-ID definitions are idempotent; divergent definitions, unknown references, and association conflicts are reported explicitly without silent overwrite.

Conflict summaries identify the stable session, body-observation, association, or definition identity and the source artifact/direction. Existing persisted content is preserved when a conflict is reported.

Synchronization addition counters describe durable inserts only. Exercise rekeys or profile enrichments remain available through the separate reconciliation counter; a compatible different-ID lookup that requires no database write is an idempotent skip. This prevents a repeated Android snapshot carrying a retired creator ID from being displayed as +1 exercice when the canonical desktop catalog row and all business tables are unchanged.

The current Marche collision is safely reconciled to desktop identity ex_b1e6ffc6-75b5-45ff-a3c0-e7433c58013d. Its catalog profile is the compatible union continuous/duration/data_fields=3; prior data_fields=1 occurrences retain their own snapshots and absent distance values. The Android occurrence sxe_f25142c8-455e-4346-9bfc-31d0989e275d retains its duration, speed, distance and equipment. No reference to the retired Android exercise identity remains in the validated merged database copy.

No SQLite file is copied.

No mounted Android filesystem is required.

The real desktop v10 database was backed up with SQLite to backups/body-zones-v1-20260909T101310Z/trainlog-v10-before.db under the Trainlog user-data directory (SHA-256 9d5dcacd8be941be17bd3b98bbbc1815944fec9dc1b18133111ca481f50684e9). The production binary migrated it to v11; integrity/FK checks pass and every row of all eight historical tables compares equal in both directions with the backup. The migration added 32 direct relations for 20 of 23 exercises and left Gym échauffement, Gym/Échauffement and Marche unclassified.

The Samsung SM-G990B application data was freshly backed up before installation under backups/body-zones-v1-android-20260909TVFprJ8/. The coherent v9 SQLite copy has SHA-256 c402b69cdbfa4912eec1553a84754af1e892fa8da0cae6c3cbd14c4f10198401; its integrity check passed and its foreign-key check was empty. The installed, built and established-keystore certificate fingerprints all matched aa56c97f2781a0d01f007f4444c3970deb58ad8327ca3da7b0b90f37dbe2ad25 before adb install -r. The normal installed migration reached v10 with every row of the 16 existing application tables plus android_metadata equal in both directions to the v9 backup. Integrity/FK checks pass, 32 direct relations cover 20 of 23 exercises, and Gym échauffement, Gym/Échauffement and Marche remain unclassified.

The real Android UI displayed primary, secondary and derived-group metadata; the chest, upper-body descendant, lower-body descendant and unclassified filters; and the Dos + lat prefix intersection. Editing Lat pull preloaded Dos and secondary Bras; cancellation left every application table unchanged. Live sync runs sy_0b00dc46-d899-4865-8718-c95085a380b2 and sy_fb0630a8-1938-4d62-9836-b0281955f625 both completed successfully. The second run reported zero additions/reconciliations, both stores retained the same 32-relation stable-ID hash, and Android application tables plus companion exercise states compared equal to the first pass. The engine accepts the exact MediaStore collision family trainlog-sync-request-v1 (N).json; request-ID replay protection remains authoritative.

Current implementation cursor

Body Zones V1, exercise reconciliation, definition-first V2 synchronization and the current real-data importer/exporter copy validation are complete. The body-zone taxonomy now supplies the read boundary required by a future zone-driven planner; no session generator or proposed-load calculation is part of this tranche.

Measured max v1

MEASURED_MAX_V1=PASS
MEASURED_MAX_ONLY_FROM_MAX_TEST=PASS

ANDROID_MAX_TEST_SESSION=PASS
EXPLICIT_MAX_RESULTS_V1=PASS
MAX_TEST_RESUME_STABLE_ID=PASS
DESKTOP_TESTS=39/39 PASS

A measured maximum belongs to an exercise occurrence in an explicit max_test session. Schema v9 introduced the positive max_weight_kg separately from sets; equipment is optional context, so one physical machine may carry independent Pec Fly and Rear Delt Fly results. Ordinary training is never promoted implicitly.

The Android and TUI max forms request no set or repetition count. Android loads a completed Test max without changing session_id, existing entry_id values, order, exercise identity, or equipment context; finalization replaces that session's children atomically, permits explicit value/equipment corrections, and may append new entries.

The current measured result is the newest successful max test. The historical record compares max tests using the same load mode.

External-load working percentages are pure calculations from the current measured load; they are not persisted and no estimated 1RM is introduced.

Body analytics v1

BODY_PROPORTION_RATIOS=PASS
BODY_SYMMETRY_ANALYTICS=PASS
NO_ESTIMATE_PERSISTENCE=PASS
DESKTOP_TESTS=39/39 PASS

Android remains capture-only for this feature.

The TUI derives analytics from canonical body observations. A local desktop-only profile provides height and the circumference-formula branch needed for the optional body-fat estimate.

No estimated body-fat, fat-mass, lean-mass, ratio, or asymmetry value is stored as if it were a real measurement.
