# Current implementation state
|
|
|
|
Snapshot date: **2026-09-16**.
|
|
|
|
This document owns the current implemented state. Historical checkpoints and
|
|
closed incidents belong in [reviews](reviews/) and the
|
|
[changelog](../CHANGELOG.md).
|
|
|
|
## Product boundary
|
|
|
|
Android is the field companion: it captures training and body data, preserves
|
|
the active draft, receives AI proposals, triggers synchronization, and shows
|
|
quick summaries. The C17/Notcurses TUI is the administration, inspection,
|
|
maintenance, import/export, and technical-tooling surface. The local Web
|
|
sibling now provides its embedded application shell; its future business
|
|
surfaces will own analysis, visualization, and program/session preparation
|
|
through Trainlog Core.
|
|
|
|
Trainlog Core owns business truth. The desktop SQLite database remains the
|
|
canonical local source of truth and long-term history; no interface owns a
|
|
parallel implementation of its rules.
|
|
|
|

|
|
Desktop and Android schema numbers are independent. Neither changes the frozen
|
|
Trainlog JSON V1 contract.
|
|
|
|
Language is device-local presentation state. Android keeps it in dedicated
|
|
SharedPreferences; desktop keeps it in the XDG configuration file
|
|
`trainlog/presentation.conf`. A successful selection updates the UI
|
|
immediately. It does not enter either SQLite database, training data, stable
|
|
IDs, schemas, exchange artifacts, synchronization protocols, AI proposals,
|
|
MAX, or feedback. User-defined exercise and catalogue names are never
|
|
automatically translated. Where a recognized stable body-zone ID has a local
|
|
presentation label, only that label is localized; unknown IDs retain their
|
|
catalogue label. Numbers, dates, and other visible formatting are owned by the
|
|
selected presentation language.
|
|
|
|
Synchronization remains a protocol boundary: core, receipt, and persisted
|
|
history summaries stay opaque operational bytes. Android and the TUI render
|
|
their current synchronization state from local typed status and counters; they
|
|
never inject a raw cross-device French summary into the visible interface. No
|
|
raw exchange or protocol format changed for interface language support.
|
|
|
|
## Storage and synchronization
|
|
|
|
- Android stores capture data in its private SQLite database.
|
|
- Android reads and writes exchange artifacts only in
|
|
`/storage/emulated/0/Documents/Trainlog` after the user grants all-files
|
|
access through system settings.
|
|
- The old SAF/tree-URI path and `Download/Trainlog` are historical recovery
|
|
boundaries, not active storage choices.
|
|
- Desktop synchronization uses direct libudev/libmtp discovery and object
|
|
access. No GVFS/FUSE mount is required.
|
|
- `trainlog_sync_run()` is shared by the TUI and `trainlog-syncd`.
|
|
- The desktop imports Android snapshots, publishes catalog/profile/feedback/AI
|
|
companions, and returns a receipt. Stable IDs and tombstones make defined
|
|
replay paths idempotent.
|
|
- SQLite database files are never synchronized.
|
|
- The desktop AI flow uses external `rclone` for Drive inbox/archive and
|
|
read-only history export. Android owns no Drive credentials.
|
|
|
|
## Android
|
|
|
|
Android currently provides:
|
|
|
|
- metadata-driven SETS+REPS, SETS+DURATION, and CONTINUOUS+DURATION capture;
|
|
- actual per-set values, optional occurrence equipment, and explicit MAX rows;
|
|
- exactly one durable active session draft with identity-preserving continuous
|
|
multi-position drag reorder,
|
|
resume, confirmed discard, and atomic completion;
|
|
- completed-session consultation, transient drag reorder, and atomic factual or
|
|
order correction while retaining session/occurrence/feedback identities for
|
|
synchronization;
|
|
- exercise catalogue editing with stable `exercise_id` and referenced-profile
|
|
protection;
|
|
- supplied/custom equipment and machine-exercise metadata;
|
|
- body measurements and recent BODY ZONES summaries;
|
|
- immediate exercise feedback, immutable wording revisions, and J+1/session
|
|
follow-ups;
|
|
- pending AI proposal collection, explicit start/delete, and durable tombstones;
|
|
- 7/30/90-day, year, and all-history quick statistics;
|
|
- direct-storage snapshot publication, sync triggering, locally rendered typed
|
|
receipt status/counters, and companion application.
|
|
- French-default/English-selectable presentation from **Settings → Language**,
|
|
applied immediately without changing repository or synchronization state.
|
|
|
|
Android does not own canonical long-term analytics. The V1 session generator is
|
|
implemented but intentionally hidden from normal navigation pending V2.
|
|
|
|
## Desktop TUI
|
|
|
|
The desktop is a strict C17 application using Notcurses. It currently provides:
|
|
|
|
- a keyboard-first seven-section shell, semantic true-color roles, UTF-8 input,
|
|
resize recovery, and a 72x20 minimum-terminal fallback;
|
|
- session creation, history, detail, and transactional correction;
|
|
- exercise and equipment catalogue management;
|
|
- explicit measured-MAX consultation and working-load calculations;
|
|
- body observation history, correction, derived analytics, and longitudinal
|
|
graphs;
|
|
- statistics derived from canonical occurrence-owned actual work, including
|
|
exact calendar-week/month buckets, performance, body, frequency, exercise,
|
|
and BODY ZONES views;
|
|
- detailed locally rendered typed synchronization status/history through the
|
|
shared engine.
|
|
- French-default/English-selectable presentation from **Settings → Language**,
|
|
including selected-language formatting without changing canonical data.
|
|
|
|
Rendering is not permitted to own SQL or business rules. Statistics are
|
|
read-only projections; they are not persisted as facts. The former Dashboard
|
|
exception is resolved: its typed Core read model owns the SQLite projection and
|
|
all characterized calculations, while the TUI supplies query state and renders
|
|
the result. The Web aggregate now exposes the distinct factual snapshot through
|
|
`GET /api/v1/dashboard` without changing the frozen TUI projection.
|
|
|
|
## Local Web
|
|
|
|
`TRAINLOG_WEB_V1` architecture, API independence, local-network boundary,
|
|
browser shell, Dashboard, layout ownership, build/runtime separation, and
|
|
security invariants are canonical. The CLI/local HTTP infrastructure and
|
|
embedded frontend shell are implemented: `-w`/`--web`, optional `--port`, exact
|
|
IPv4 loopback binding, `/api/v1/health`, React navigation and the persistent
|
|
Header/Body/Footer shell. Production assets are generated from the npm lockfile
|
|
and linked into the binary. The read-only Dashboard business snapshot and
|
|
factual Footer integration exist; no grid engine, business mutation, automatic
|
|
browser launch or layout persistence exists yet.
|
|
|
|
## Data semantics
|
|
|
|
- `exercise_id` identifies a catalogue exercise; `entry_id` identifies one
|
|
ordered occurrence in a session.
|
|
- Plans and performed work are distinct. A continuous activity is not a fake
|
|
performed set, and actual repetitions may be heterogeneous.
|
|
- Explicit MAX results are occurrence-owned and distinct from ordinary best
|
|
sets. Equipment/resistance/execution context remains relevant.
|
|
- BODY ZONES are a UX/business projection over explicit scientific knowledge,
|
|
not a complete anatomical taxonomy.
|
|
- Feedback roots retain identity while append-only revisions preserve wording
|
|
history. J+1/session follow-ups are session-owned.
|
|
- AI proposals contain target-only plans and never create performed work,
|
|
history, MAX, or feedback until the user explicitly starts and completes a
|
|
normal capture draft.
|
|
|
|
## Validation status
|
|
|
|
The durable commands are owned by [tests.md](tests.md). On 2026-09-15 final
|
|
validation passed desktop compilation, **60/60 normal Meson tests** and
|
|
**60/60 ASan/UBSan Meson tests**, Android debug assembly and **202 Android
|
|
tests (198 passed, 4 skipped, 0 failed)**, the JSON validator, and the
|
|
import-contract validator. The source-derived TUI
|
|
`TRANSLATABLE_UI=0` check and Android resource parity also passed. Link and
|
|
diff safety checks pass in the final audit evidence.
|
|
|
|
The Dashboard Core extraction tranche passes **62/62 normal Meson tests** and
|
|
**62/62 ASan/UBSan Meson tests**, including the standalone public-header and
|
|
Core characterization targets, plus both canonical JSON validators.
|
|
|
|
The CLI/HTTP infrastructure tranche passes **67/67 normal Meson tests**, adding
|
|
pure CLI parsing, process-level help/version checks and an isolated loopback
|
|
HTTP lifecycle/security suite. The same suite is required under ASan/UBSan.
|
|
|
|
The frontend shell tranche passes **70/70 normal and ASan/UBSan Meson tests**,
|
|
including TypeScript typecheck, 10 Vitest component tests, deterministic asset
|
|
generation bounds, real embedded-asset HTTP coverage, SPA/API separation and
|
|
runtime execution without Node/npm or `web/dist`.
|
|
|
|
The Dashboard data-contract tranche passes **71/71 normal and ASan/UBSan
|
|
Meson tests**, including the bounded Core/JSON target, HTTP endpoint coverage
|
|
and 12 Vitest tests for parsing and factual Footer integration.
|
|
|
|
`TRAINLOG_I18N_V0_1_1=PASS` is covered by desktop presentation, persistence,
|
|
formatting, layout-invariance and source-derived text-boundary tests, plus
|
|
Android resource-parity, language-owner, typed sync-presentation, and
|
|
stable-data presentation tests. A real-device/manual visual language-switch
|
|
smoke remains a manual validation; it does not change the validated status.
|
|
|
|
Hardware-dependent MTP and the final real Drive plus Android-triggered AI-draft
|
|
smoke test are not automated. The latter is why
|
|
`TRAINLOG_AI_SESSION_DRAFT_V1` remains `VALIDATION_PENDING`.
|
|
|
|
## Active limitations
|
|
|
|
- `WEB_DASHBOARD_DATA_CONTRACT_V1=PASS/FROZEN`: the bounded Core snapshot,
|
|
`/api/v1/dashboard`, explicit unavailable states and factual Footer data are
|
|
implemented. The seven tile bodies intentionally retain shell placeholders.
|
|
- `APP_SHELL_V1` still awaits the recorded human visual/accessibility review.
|
|
- AI proposal exchange still awaits one real Drive plus Android-triggered
|
|
bidirectional smoke test.
|
|
- Session Generator V1 is hidden while V2 planning semantics are developed.
|
|
- Hardware MTP validation requires a connected unlocked Android device.
|
|
- Scientific knowledge is bounded to reviewed catalog entries; unknown custom
|
|
exercises remain unclassified rather than inferred from names.
