Current implementation state

Full-generation Web synchronization now selects an actually usable MTP peer before USB, falls back to a separately configured private Drive generation namespace, and mirrors successful USB conversations to Drive on a best-effort basis without rolling back USB. Both transports move the same generation/ACK bytes; neither transports SQLite. Android has an explicitly enabled foreground USB listener with mandatory notification and a private-folder Drive grant with bounded WorkManager checks. Both use the same concurrency-guarded generation coordinator as SyncScreen. That coordinator has one process-wide ownership arbiter: explicit foreground intent has priority over automatic background resumption, while the foreground service may remain alive without owning the conversation. An automatic run yields cooperatively at safe boundaries; its durable generation is retained for a correlated handoff rather than deleted. Background actionability distinguishes a new request or new correlated remote evidence from a merely stale resumable generation, preventing five-second terminal retry loops.

Direct-MTP publication now has an explicit Android visibility boundary. Durable immutable generation files are submitted to MediaProvider and all scan callbacks complete before the mutable generation reference is published; the reference and Android ACK use the same confirmation. Bounded diagnostic logs contain only run/generation identities, artifact names, phases and results. The desktop worker performs lightweight local correlation checks continuously but opens a full MTP pull no more than once every three seconds. A 30-second individual adapter budget is distinct from the overall conversation deadline, so an absent correlated generation reports a protocol wait timeout while an actually blocked adapter reports transport_timeout.

The resumed private run sy_9639f06e-58ba-4bc0-ab1b-1488aefe011c received its desktop request and archive-ACK files, captured generation gen_532da95e-713f-4163-acc1-d838673c33bf, and published its immutable objects and reference with manifest SHA-256 170b55ad5bf3e44501fb506107cd26ab807d0179c95a5f1bf73f8251ea1a14e8. Filesystem and MTP exposed the same bytes. It then waited for a desktop ACK that could not arrive because the daemon correctly refused to create another conversation for the already-consumed request UUID. No causal or business mutation occurred. The remaining defect was Android ownership: an automatic resume could hold the old run while the explicit foreground attempt failed before publishing a fresh request UUID. The arbiter and explicit run baseline now prevent that state.

Existing preparation rows expose separate editing and Android-delivery states and an accessible send action. Draft/local advances the same preparation to a ready revision before delivery; ready/local delivers the current revision. Completed history hides the active preparation exclusively through the delivery's stable execution-session identity and retains all provenance. Starting a delivered mixed preparation preserves continuous duration targets and set/repetition/load/rest targets in the active singleton without creating performed continuous activity, performed sets, MAX results, history, or feedback before explicit user capture. The active-session editor accepts target-only continuous and set-based occurrences: opening an existing stable entry renders its prefilled form, keeps the independent target intact on save, and leaves sibling occurrences unchanged on save or cancellation. A set-based target-only occurrence can add or change equipment without fabricating a performed set.

The opt-in full-generation path is operational on the private daily installation. Android explicit synchronization uses a dedicated coordination filename carrying the unchanged request-v1 payload. Legacy V3 signalling is additive and occurs only after a fresh strict V3 snapshot succeeds; daemon request identities are deduplicated across both bounded channels. The loopback Web control and foreground Android coordinator use the production direct-libmtp adapter, correlated manifest/ACK V1 objects, and persistent peer identities. Controlled USB and private Drive validation proved the complete Web-initiated request, generation, import, publication, and ACK conversation without opening SyncScreen for each run. USB remains preferred; the private Trainlog/Sync/v1 namespace is configured as a verified mirror and fallback, independently from Trainlog/AI. Cross-transport replay is idempotent and neither transport carries SQLite.

The public Android release chain advances from v0.1.1 versionCode 2 through v0.1.2 versionCode 3 to v0.1.3 versionCode 4 under certificate SHA-256 5ef41117da107c9805ae3215c5ec823cff06216610e6e4f7542a754161c71bd2. Higher-numbered private validation builds used a separate Android Debug certificate and are not members of the public update-signature chain.

TRAINLOG_NATIVE_BUILD_AND_CANDIDATE_V1 closes the native warning gate. Strict GCC 16.2.1 and Clang 22.1.8 builds now pass the same 81-test inventory, and the Clang ASan/UBSan build passes it with leak detection. Bounded path assembly and the Web sync accepted response reject insufficient capacity without publishing partial output. Fresh desktop, current-Android and schema-v17 bridge candidates were rebuilt from code commit dd8c91a946a9c836965818d8cc35b8f8bce74658. The rollout packager now keeps the legacy request daemon and one-shot helper in the same relocatable, hashed bundle as the Web generation coordinator, avoiding mixed-checkout user-service execution during the controlled rollout.

Snapshot date: 2026-09-20.

TRAINLOG_CODE_READABILITY_V1 normalizes the recent generation-MTP, generation/ACK, Android-backup, Web Dashboard serialization, tests, doubles and packaging workflows without changing their contracts. The scoped C formatter check is canonical for those files only; it does not claim that the historical repository has been globally reformatted.

This document owns the current implemented state. Historical checkpoints and closed incidents belong in reviews and the changelog.

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 and implemented Dashboard; its future business surfaces will own broader analysis, program/session preparation, and exercise workflows 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.

Schema v19/v18 now persists enriched history (ended_at, causal session, occurrence and observation notes, and observation-to-session links), stable execution-draft identities, bounded pending drafts and finalization ledgers. The explicit trainlog-mobile-export V4 and trainlog-execution-drafts V1 codecs are validation-stage entry points only. The active sync engine and Android inbox/outbox still select V3 and do not move the draft artifact.

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() remains the strict legacy V3 engine shared with the TUI and compatibility tooling. When the trusted full-generation configuration is present, trainlog-syncd admits the Android request into the existing sync_orchestrator.py/sync_peer_worker.py conversation; configuration absence retains the legacy fallback.
• The desktop imports Android snapshots, publishes catalog/profile/feedback/AI companions, and returns a receipt. Stable IDs, artifact idempotence and the few domain-specific explicit states make defined replay paths idempotent. Explicit staged generation services now provide coherent V4/companion capture, immutable manifests, whole-generation SQLite consumption and durable peer ACKs. The Android foreground trigger now publishes a complete generation by default. A trusted desktop configuration selects the bounded production generation MTP adapter; absent configuration leaves V3 as the compatibility fallback.
• 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.

The frozen complete synchronization gap contract remains the authority for the later orchestrator. Mobile V3 still omits ended_at, session/occurrence/body-observation notes, the body-observation to session link and the active Android draft. Legacy imports remain transactional per artifact. Explicit generation consumption instead validates every listed artifact, applies all domains and its consumption record in one transaction, and emits consumed only after commit. A legacy receipt remains distinct from the correlated generation ACK. Characterization now also freezes the observed preservation of local-only session/body values on an identical replay, loss of an occurrence-local note when V3 correction reconstructs that occurrence, delete-before-send exposure, request replay/receipt marking, and real inter-process lock contention. These are current-behavior proofs, not lifecycle repairs.

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;
• complete scrollable equipment selection and caller-aware creation from an active occurrence editor, with the explicit catalogue-created ID selected on return and the occurrence identity, plan, raw form and siblings retained for in-place save;
• 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 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 uses one typed Core snapshot, a seven-tile responsive grid, factual size-adaptive tiles, an ECharts progression series, an original BODY ZONES SVG, and private versioned layout persistence with optimistic conflict and CSRF/Origin protection. It provides no automatic browser launch. Sessions provides complete paged preparation, resume and history views, stable details, optimistic manual-preparation writes, explicit proposal derivation and generation-backed Android delivery. The top-level /programmes route is an operational daily active-Program calendar; Sessions → Programmes remains the technical administration/import, list, detail, archive, and delete surface. /exercices is the operational desktop catalogue administration surface. /analyse is implemented with Overview, Exercises, Distribution, and Measurements sections over one bounded Core read model. Its global 7/30/90-day/all filter is applied in the backend; Dashboard uses the same 30-day calculations for activity, active-Program progress, exercise progression, measurements, and BODY ZONE links.

The Analyse API validates period, exercise identity, measurement metric and page, rejects unknown or duplicate parameters, and bounds exercises and chart points. Missing facts remain null. Exercise output respects persisted tracking/load modes, explicit MAX rows are never estimated, and duration, distance, speed, external load, and external volume appear only when their source observations support them. BODY ZONES are labelled as recorded primary zone exposures/associated sets rather than physiological percentages. All fourteen stored body metrics expose period-first, period-last, and an absolute delta only with at least two points. The route and Dashboard deep links have safe invalid-query fallbacks, French/English labels, keyboard controls, and responsive no-overflow layouts. Visual inspection remains pending before any freeze marker.

Exercises uses bounded Core-owned list/detail reads, canonical name normalization, BODY ZONES taxonomy, profiled creation/update commands and causal retirement. Its deterministic optimistic token covers all editable catalogue state. Built-in identities cannot be retired, equipment associations are presented read-only, and profile edits affect future use only: occurrence snapshots, performed sets, feedback and MAX history are never rewritten. A successful mutation changes only the canonical desktop database; the existing USB-priority, Drive mirror/fallback synchronization later carries the existing catalogue/profile/BODY ZONES/causal artifacts. No Web mutation invokes sync.

The calendar uses the existing typed Core services fetchAllPrograms(active), fetchProgram, and createPreparationFromProgram; it derives no local program or execution state. With no active Program it shows an empty state and navigation to Sessions administration; with one it selects it automatically; with several it offers a non-persisted selector. Its continuous Monday–Sunday weeks derive from Program bounds and real planned_for dates, do not invent rest-day sessions, and retain undated sessions in a separate section. It shows all five Core execution states; only todo offers Prepare. Each Prepare result is followed by an authoritative Core reread and may expose the returned preparation link. This calendar adds no Android delivery, start, or execution behavior.

Desktop schema v26 owns immutable manual-preparation revisions, stable ordered occurrences, persistent HTTP idempotency keys, delivery-to-execution identity, and durable revision-bound withdrawal records. Android schema v24 stores received preparations and permanent withdrawal results separately from AI proposals and the active singleton. Pending deliveries are cancelled by an exact V2 withdrawal; started executions are preserved. An exact correlated ACK is required before delivery or withdrawal is shown as acknowledged.

Sessions and the prepared-items Dashboard projection now share descending planned-date presentation with timestamp and stable-identity tie-breaks. Web dates default to French presentation, with an installation-local versioned ISO preference outside business SQLite and synchronization. Contextual French state labels and persisted proposal provenance replace raw enums and digest-only presentation. The preparation detail exposes a protected, idempotent Delete preparation action; withdrawn rows remain technically inspectable but cannot be edited or delivered.

Sessions rows expose independent right-edge trash actions and an accessible destructive confirmation dialog. Proposal withdrawal preserves derived preparations and is propagated by trainlog-ai-session-drafts V2; inactive execution drafts and completed sessions use revision-guarded causal deletion. Active or concurrently changed drafts conflict instead of being erased.

Program V1 is desktop-owned planning data in schema v26. The responsive Sessions Programs subtab provides cards and timeline detail backed by real imported definitions, sessions, usage, and provenance; it keeps strict bounded preview/commit import and deterministic replay/conflict behavior. A discrete, accessible trash action uses confirmation, focus restoration, and Escape-safe cancel semantics. Active and archived programs may be terminally logically deleted; sources and derived preparations remain, while deleted programs cannot resurrect or reprepare and archived programs cannot prepare.

Android schema v24 contains a read-only synchronized Programs projection with program, session, entry, and deletion tables. Its Sessions list/detail has no program mutation actions. The optional staged controlled-generation trainlog-programs V1 companion publishes a PC-to-Android full nondeleted snapshot plus unacknowledged tombstones under capability programs-v1; a durable correlated ACK records acknowledgment. It changes neither TRAINLOG_FORMAT_V1, mobile V3, catalog exchange, nor preparations.

Android schema v25 makes those projected sessions executable through the existing durable singleton. Stable paired Program provenance survives draft restart and completion. The optional Android-to-desktop trainlog-program-executions V1 companion records in_progress or completed against desktop schema v27 without transferring ownership of Program definitions. Web and Android derive their session state from these persisted identities; no display-field heuristic is used.

Android is capture-first: its drawer no longer exposes Statistics, and Home is limited to capture, recent BODY ZONES exposure, synchronization, and body measurements. A shared compact card/button system covers Sessions, Programs, drafts, exercise catalog/detail/editing, synchronization, Settings, and MAX presentation. Program list/detail surfaces show completed counts and explicit todo/in-progress/completed states; the active editor uses exclusive side-by- side session-type controls and compact two-column set cards. These are presentation changes only and do not alter schemas or exchange artifacts. Web Program administration retains revision-guarded deletion and now presents adaptive cards plus an explicit completed-session progress indicator. The full Android lint comparison against an isolated clean main worktree is unchanged at ten pre-existing errors: one NewApi, one LocalContextConfigurationRead, and eight bilingual StringFormatMatches diagnostics. This UI tranche adds no lint error and changes no lint policy. The next private daily Android candidate remains on development versionName=0.1.4; only its strictly increasing versionCode may be supplied as a build-time override. No public tag or release is created by that private candidate process.

The private Program execution rollout installed desktop schema v27 and the signed nondebuggable Android versionCode 17/schema v25 update without uninstalling or clearing application data. A strictly disposable Program was synchronized to Android, started, left and resumed through the durable singleton, and completed as session se_6bb66f59-a6fb-4759-a75d-c1a79ea107e8. Android displayed Effectuée and desktop/Web received the same completed provenance through the real program-executions-v1 producer and consumer. A second exchange created no duplicate and no second active draft. The disposable Program was then deleted through the revision-guarded Web command; Android retained exactly one tombstone and desktop retained exactly one acknowledged deletion ledger row. After both stores and the Trainlog components were reopened, exact replay of the preserved pre-deletion Android generation returned its production durable ACK without duplicating the execution or resurrecting the Program. A final correlated exchange remained completed with no missing capability. The real Program remains active and unique with 24 sessions and 164 ordered entries.

The private Programs rollout migrated desktop schema v25 to v26 and Android schema v23 to v24 after verified backups, then installed the signed non-debuggable versionCode 16 APK without uninstalling or clearing data. The real 24-session Program remained unique and readable on Web and Android. A clearly disposable Program was imported, synchronized, cancelled once without mutation, then logically deleted through the Web confirmation. Android consumed the real tombstone and desktop recorded its correlated generation ACK. A first post-restart attempt failed before generation with device_unavailable and PTP_ERROR_IO; no success state was recorded. Releasing the stale bounded MTP worker and restarting the local ADB server restored the same physical peer. The subsequent correlated exchange completed in both directions, and store reopen confirmed one durable Android tombstone, one acknowledged desktop deletion, no duplicate Program, and no resurrection.

The controlled deployment preserved the installed Android signing identity and advanced its private versionCode from 13 to 14 without uninstalling or clearing data. The requested six-occurrence validation preparation was already started on Android at preflight, so withdrawal retained its immutable delivery and returned execution_preserved; it did not delete or complete the reserved execution. The source proposal retained its identity, archived state, content and publication timestamp. Two correlated post-withdrawal generation conversations, separated by component restart, completed without resurrection, duplicate withdrawal, performed fact, or draft mutation.

The Next Session tile no longer treats the frozen Dashboard next_session.available placeholder as a durable inventory. A separate bounded GET /api/v1/prepared-items Core projection distinguishes manual preparations, imported AI proposals, and active or pending execution drafts and exposes stable identity, state, title/date, occurrence count, and provenance. Reload and later sync failure do not erase the last successfully read projection. Proposal targets remain planning data and never alter Dashboard actual-work metrics.

Full-generation MTP publication now uses a private phase-owned outbox. The request, desktop consumption ACK, and current desktop generation are published only when their phase requires them; retained staging, inbound objects, legacy files, prior ACKs, and causal evidence are not recursively re-uploaded. Adapter timeouts are persisted as the stable transport_timeout status instead of a truncated Python traceback. The browser polls through one abortable scheduler, orders revisions per run_id, and rejects stale responses from older runs. The reciprocal MTP read is bounded to the Android peer advertisement, current generation reference and consumption ACK, plus the single Android generation named by that reference. Historical generations and other retained evidence are neither traversed nor deleted during polling. Before peer validation, MTP mode now requires one successful current-device pull; a retained pre-upgrade advertisement can no longer cause a false missing-capability failure.

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. At commit 14b863eb0f159d46891f4ad5cf076b3aa0a11bba on 2026-09-17, isolated validation passed desktop compilation, 75/75 normal Meson tests and 75/75 ASan/UBSan Meson tests, Android debug assembly and 203 Android tests (199 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 passed in that checkpoint evidence. These are historical results for that commit, not executions performed by later documentation work. The four Android skips were the optional historical v9, v12, v13, and v14 database-fixture migration cases. Hardware MTP, real Drive, and Android instrumented tests were not part of that isolated run.

For TRAINLOG_SYNC_CHARACTERIZATION_V1 on 2026-09-17, the isolated JDK 17 preflight, smoke, and full modes passed. The final full run passed desktop compilation, 75/75 normal Meson tests, 75/75 ASan/UBSan Meson tests, the explicit production-path sync-gap characterization, both JSON/import contract validators, the targeted Android draft lifecycle test, Android debug assembly, and 204 Android tests (200 passed, 4 skipped, 0 failed/error). The added Android↔desktop↔fresh-Android V3 round trip runs inside that Android total. The four skips remain the documented optional historical v9, v12, v13, and v14 database fixtures. No hardware MTP, real Drive, adb, instrumented device test, user database, exchange directory, or user service participated.

For the TRAINLOG_SYNC_DATA_LIFECYCLE_V1 closeout on 2026-09-17, real staged V4 history and execution-draft entry points completed both Android/desktop producer directions through fresh destination databases. The closeout fixed one Android V4 import defect that validated but failed to persist occurrence plan fields. Isolated validation passed 75/75 normal Meson tests, 75/75 ASan/UBSan Meson tests, Android debug assembly, and 207 Android tests (203 passed, 4 skipped, 0 failed/error). The four skips remain the optional real historical v9, v12, v13, and v14 database fixtures. The active transport remains V3; no phone, MTP, Drive, service, user database, deployment, or instrumented device test participated.

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.

WEB_DASHBOARD_GRID_V1=PASS/FROZEN uses react-grid-layout 2.2.4 behind an independent Trainlog model/validator. Its 12-column desktop layout has seven stable tile IDs, bounded per-tile dimensions, vertical collision compaction, explicit edit/cancel/reset behavior, mouse drag/two-axis resize, an announced keyboard alternative, and derived six/one-column responsive projections. Persistence is supplied by the following frozen slice.

WEB_DASHBOARD_LAYOUT_V1=PASS/FROZEN adds a strict versioned seven-tile file under the private XDG configuration directory, backend revalidation, atomic 0600 replacement, ETag/If-Match conflict control, Origin plus ephemeral CSRF protection, and durable React load/save/reset behavior. Only the desktop 12-column canon persists.

WEB_DASHBOARD_TILES_V1=PASS/FROZEN renders all seven domains from the one validated /api/v1/dashboard snapshot. Compact, medium and large densities only reveal existing facts. Activity uses a factual CSS day map, MAX lists are bounded 1/3/8, and muscle bars encode session_count only. Unavailable, partial, invalid and transport-error states never synthesize values.

WEB_DASHBOARD_VISUALIZATIONS_V1=PASS/FROZEN uses a lazy, modular Apache ECharts 6.1.0 SVG line chart for medium/large Progression tiles. Every real point remains visible, smooth=false, legacy zeroes are preserved, and only Core-owned improved flags alter markers. An original React SVG supplies front/back BODY ZONES regions whose discrete colour level depends solely on session_count; the factual text list remains authoritative and accessible.

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 is not automated. The controlled real-device rollout validated two consecutive post-withdrawal full-generation exchanges around a Trainlog component restart. Android retained exactly one withdrawal result as execution_preserved, retained the linked delivery as started, and exposed no active preparation or start action after replay. Desktop retained exactly one acknowledged withdrawal and no active preparation. The source AI proposal was verified with its original identity, state, entry content and publication timestamp; no proposal-to-execution-draft conversion was performed.

Active limitations

TRAINLOG_SYNC_CAUSAL_DELETE_V1=PASS/FROZEN provides isolated Android and desktop producers/consumers for trainlog-causal-deletions V1. All contracted domains are durably protected; exact replay is idempotent and unprovable or concurrent ancestry conflicts before mutation. Protected legacy snapshots are refused before resurrection. The default automatic daemon path remains V3, while the trusted local Web opt-in now runs the deployed full-generation path. Its acknowledged generations can leave the active admission window only through the verified schema-v22/schema-v21 archive ledger; pending, rejected and ambiguous generations remain protected.

The focused causal closeout additionally proves child-data delete/update conflicts including change-and-revert, imported built-in and alias protection, active/pending/desktop draft-revision equivalence, protected companion refusal, current-view retirement and bounded pre-effect admission. The later generation slice additively advances schemas to desktop v22/Android v21 without changing default automatic V3 selection.

The residual causal evidence also proves legitimate Android and desktop producer directions separately for exercise retirement, populated body observation deletion, custom-equipment retirement, multi-revision feedback withdrawal and BODY ZONE relation removal. Production exchanges establish each replica before deletion; stored effects, current readers, stale-companion refusal and exact replay are checked after reopening the receiving store.

The isolated closeout passed 76/76 normal Meson tests, 76/76 ASan/UBSan tests, Android debug assembly, and 211 Android tests (207 passed, four optional historical-fixture skips). Strict desktop builds use Clang 22.1.8; the compared pre-existing GCC 16.2.1 Web warning gate remains documented rather than green.

• TRAINLOG_WEB_EXERCISES_V1=PASS. TRAINLOG_WEB_ANALYSIS_V1 is implemented on the 0.1.4 branch and awaits the requested Dashboard/Analyse visual review.
• APP_SHELL_V1 retains a recorded legacy visual/accessibility review gate; its observations are inputs to, not decisions for, the new 0.1.3 Android contract.
• 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.
