Roadmap

The controlled private rollout is complete for the paired daily installation: physical libmtp, verified backups, signing continuity, migrations, correlated ACKs, restart, and idempotent replay passed. Generation mode remains an explicit per-installation opt-in. The additive private Drive transport and Android background software are implemented and validated with fake transport and the private production namespace. USB remains preferred, Drive is the configured mirror/fallback, and Android background operation retains its documented post-reboot platform limits.

This document owns future work. The implemented baseline is summarized in current_state.md; completed narratives and evidence belong in reviews and CHANGELOG.md.

Product boundary

Trainlog Core owns business truth and canonical desktop persistence.
The TUI administers, inspects, maintains, and imports/exports.
The local Web analyzes, visualizes, and prepares programs/sessions.
Android executes in the field, captures actual work/feedback, and returns data.

Future work must preserve the frozen Trainlog JSON V1 contract, stable identities, actual-versus-planned separation, direct MTP transport, and the distinction between measured values and estimates.

Current baseline

Stable v0.1.2 is the release baseline. Desktop schema v28, Android schema v25, Notcurses, direct Documents/Trainlog storage, mobile export V3, Training Knowledge V1, Body Zones V1, Training Feedback V1/V2, STATS V1, and Session Generator V1 are implemented. Session Generator V1 is hidden pending V2. AI session-draft exchange and APP_SHELL_V1 retain their explicit manual validation/review gates. TRAINLOG_WEB_V1=CONTRACT_FROZEN / IMPLEMENTATION_STARTED; its local-only CLI/HTTP infrastructure, embedded frontend shell and the frozen Dashboard data contract, frozen interactive grid, versioned layout persistence and factual tile rendering exist. The Dashboard's bounded progression and BODY ZONES visualizations and Sessions V1 are implemented. The top-level /programmes route is an operational daily active-Program calendar, while Sessions → Programmes remains the technical administration/import, list, detail, archive, and delete surface. Analyse and Exercises remain placeholders or out of scope. The corrective prepared-item projection, bounded phase-owned MTP outbox, Sessions presentation correction, local date preference and durable preparation withdrawal are implemented. The withdrawal uses the separate versioned session-preparations V2 participant and does not change the frozen Dashboard, mobile snapshot or TRAINLOG_FORMAT_V1 contracts.

Current cursor

The stable v0.1.2 baseline is closed; future work proceeds from its validated Web, Program execution, USB/Drive generation, ACK, and causal-deletion contracts without reopening those completed gates.

CURRENT_OPERATIONAL_CURSOR=TRAINLOG_WEB_V1_NEXT_CONTRACT

The focused TRAINLOG_SYNC_CAUSAL_DELETE_V1_CLOSEOUT is complete before this cursor: complete predecessor state, imported built-in authorization, cross-platform draft revision identity and resource-bound admission are closed. TRAINLOG_SYNC_GENERATION_ACK_V1=PASS/FROZEN: both platforms expose explicit coherent capture, immutable manifest publication, whole-generation transactional consumption, durable correlated ACK and restart/replay entry points. The orchestrator, Web API and Web control are complete behind an explicit trusted opt-in. The authorized private direct-MTP rollout passed on real hardware; automatic V3 selection remains unchanged without that opt-in. The next separately contracted Web surface is Exercises. Sessions deletion and its Programs subtab are complete in software and are not reopened by that future contract. TRAINLOG_PROGRAMS_PRESENTATION_ANDROID_DELETE_V1=PASS after its coordinated private desktop/Android deployment, correlated deletion ACK, and post-restart non-resurrection validation. It must not be reopened by the Exercises contract.

TRAINLOG_PROGRAM_EXECUTION_FLOW_V1=PASS after its coordinated private desktop/Android rollout, real start/resume/completion, correlated program-executions-v1 exchange, idempotence exchange, component restart, preserved-generation replay, and disposable-Program deletion proof. It also must not be reopened by the Exercises contract.

TRAINLOG_SYNC_GAP_CONTRACT_V1=CONTRACT_FROZEN / IMPLEMENTATION_IN_PROGRESS defines the complete-sync target and its bounded dependency order. TRAINLOG_SYNC_TEST_ENV_V1=PASS/FROZEN supplies the reproducible isolated desktop/Android validation entry point, JDK 17 gate and private JVM/XDG paths. TRAINLOG_SYNC_CHARACTERIZATION_V1=PASS/FROZEN reuses and completes the current-behavior evidence for cross-implementation V3 exchange, identities, ordering, replay, partial publication, request/receipt processing and the real lock. Data lifecycle, causal deletion, and generation/ACK slices are complete; the orchestrator/report slice remains next and does not authorize an endpoint, button, deployment, or transport activation here. Contract details.

WEB_FRONTEND_SHELL_V1=PASS/FROZEN. trainlog -w serves the embedded React, TypeScript and Vite shell with its five client routes, Catppuccin Mocha design system, permanent Header/Footer, empty-data states and health status. The Dashboard slices below are complete; this does not authorize implementation of the remaining route placeholders. WEB_DASHBOARD_GRID_V1=PASS/FROZEN adds the validated 12-column desktop grid, explicit edit mode, drag/resize, keyboard alternative and derived responsive projections without persisting layout state. WEB_DASHBOARD_LAYOUT_V1=PASS/FROZEN persists only that canonical desktop layout with atomic XDG storage, optimistic revisions and protected HTTP mutations; responsive projections remain derived. WEB_DASHBOARD_TILES_V1=PASS/FROZEN replaces every shell placeholder with a size-adaptive component consuming only the frozen Dashboard snapshot. WEB_DASHBOARD_VISUALIZATIONS_V1=PASS/FROZEN adds a factual time-series chart for the Core-selected performance identity and an original accessible BODY ZONES silhouette, without changing either domain's semantics. WEB_DASHBOARD_V1=PASS/FROZEN closes the complete Dashboard after its final functional, visual, responsive, accessibility, persistence and performance review.

TRAINLOG_WEB_V1 implementation gate

Implementation order is fixed as:

WEB_DASHBOARD_CHARACTERIZATION_V1
        -> WEB_DASHBOARD_CORE_READ_MODEL_V1 [PASS/FROZEN]
        -> WEB_TUI_READ_MODEL_ADOPTION_V1 [PASS/FROZEN]
        -> WEB_CLI_HTTP_INFRASTRUCTURE_V1 [PASS/FROZEN]
        -> WEB_FRONTEND_SHELL_V1 [PASS/FROZEN]
        -> WEB_DASHBOARD_V1 [PASS/FROZEN]

The Web must not start with React. Characterization proves current behavior; Core extraction establishes one business implementation; TUI adoption proves reuse; only then may trainlog -w, the loopback HTTP adapter, embedded assets, and browser UI be introduced. Initial API delivery is read-only. Later program and session writes require explicit transactional Core command services.

TRAINLOG_WEB_V1 preserves /api/v1/ as an independently versioned boundary, the 127.0.0.1:8080 default, explicit --port, no silent port fallback, a single serialized Core/SQLite owner, build-only Node/npm, and no change to business SQLite or frozen exchange formats. Dashboard Activité and Progression semantics are now frozen by WEB_DASHBOARD_DATA_CONTRACT_V1; future rendering must consume them without reconstructing or redefining their mathematics.

WEB_DASHBOARD_V1 advances through independently reviewable slices:

WEB_DASHBOARD_DATA_CONTRACT_V1 [PASS/FROZEN]
        -> WEB_DASHBOARD_GRID_V1 [PASS/FROZEN]
        -> WEB_DASHBOARD_LAYOUT_V1 [PASS/FROZEN]
        -> WEB_DASHBOARD_TILES_V1 [PASS/FROZEN]
        -> WEB_DASHBOARD_VISUALIZATIONS_V1 [PASS/FROZEN]
        -> WEB_DASHBOARD_V1_FINAL_REVIEW [PASS/FROZEN]

The completed slice order preserves Core ownership, keeps visual layout outside business SQLite and frozen formats, and specifies Activity/Progression before rendering those metrics. Later Dashboard evolution must preserve those frozen boundaries.

WEB_NEXT_MODULE_SELECTION_V1 remains a future Web documentary cursor. The current roadmap does not yet establish a contract order between the remaining placeholder routes, Analyse and Exercices. This cursor must inventory their existing Core services, read/write boundaries and dependencies, then select one bounded module contract; it does not authorize silently implementing a page.

Next

Complete synchronization implementation

The frozen contract orders future bounded lots as environment/test, characterization, data/lifecycles, causal deletion, generation/consumption/ack, orchestrator/report, Web API, then button/refresh. The environment/test and characterization and data/lifecycle lots are complete. Enriched V4 history and the separate execution-draft codec are implemented behind explicit entry points, while active transport remains V3. Causal deletion is implemented and validated through explicit staged entry points, including both real producer directions for every contracted target kind; generation/consumption acknowledgement, orchestration/reporting, Web sync, the production generation MTP adapter and complete Android backup/restore are implemented on the development branch. Remaining gates are physical-device validation, signed bridge/current APK procedures, real user backups and an explicitly authorized rollout. WEB_DASHBOARD_V1=PASS/FROZEN remains closed and unchanged.

Gym catalog V1

Build an inventory from the equipment actually available in the user's gym. Keep physical equipment, exercises, movement patterns, muscles, and BODY ZONES distinct. One photographed machine may support several exercises. Record model or manufacturer only when evidence identifies it.

Exercise metadata V1

After the gym inventory is normalized, design any remaining structured metadata such as movement family and laterality. Reuse existing equipment and BODY ZONES identities; do not encode semantics in display names or notes.

Session Generator V2

Replace the hidden V1 product surface with duration-aware construction that can represent warm-up, ramp-up, main work, cool-down, transitions, setup time, and candidate scarcity without claiming unsupported physiological precision.

Session templates V1

Offer editable conveniences built on the real catalogue and planning model. Templates are not rigid prescriptions and never become performed work before normal capture.

Later

  • evolve training analytics only where sufficient real history supports the metric, without aggregating incomparable loads;
  • add body baseline and trend comparisons while keeping direct measurements distinct from estimates;
  • add conservative, editable progression suggestions with correct external-load and assistance interpretation;
  • support explicit user objectives without mandatory gamification;
  • add user-controlled dated backup and complete/period-limited exports.

Canonical order

WEB_DASHBOARD_CHARACTERIZATION_V1
        -> WEB_DASHBOARD_CORE_READ_MODEL_V1
        -> WEB_TUI_READ_MODEL_ADOPTION_V1
        -> TRAINLOG_WEB_V1
        -> REAL_DATA_BASELINE_V1
        -> GYM_CATALOG_V1
        -> EXERCISE_METADATA_V1
        -> SESSION_GENERATOR_V2
        -> SESSION_TEMPLATES_V1
        -> ANALYTICS_EVOLUTION
        -> BODY_ANALYTICS_V2
        -> PROGRESSION_ASSIST_V1
        -> OBJECTIVES_V1
        -> BACKUP_EXPORT_V1

Outstanding validation gates

  • APP_SHELL_V1=IMPLEMENTED_AWAITING_VISUAL_REVIEW_2: complete the recorded human visual/accessibility matrix without redefining product semantics.
  • TRAINLOG_AI_SESSION_DRAFT_V1=VALIDATION_PENDING: complete one real Drive plus Android-triggered bidirectional synchronization smoke test.

Permanent constraints

Do not regress to SQLite-file synchronization, a mandatory mounted Android filesystem, exercise-name identity heuristics, fake sets for continuous work, synthetic uniform actuals, ordinary training promoted to measured MAX, assistance interpreted as external load, or estimates presented as direct measurements. Incompatible exchange semantics require a new version. Web UI configuration remains outside training data, scientific/AI exports, session synchronization, and business SQLite. Browser, React, TUI, and Android must not query desktop tables or duplicate Core calculations.
