+
+- A Commonlib or service operation should normally record detailed diagnostics at `LOG_LEVEL_VERBOSE` and return a typed result which lets its caller distinguish complete, partial, and failed outcomes. Do not make callers infer an outcome by parsing log text.
+- Detailed diagnostics may be long and remain in English when they are intended for tracing and the generated report. Include enough context to identify the operation, affected target, and remaining state or retry behaviour.
+- The application boundary which owns the workflow should decide whether to raise `LOG_LEVEL_NOTICE`. It has the interaction context to describe the user-visible consequence and the next useful action; an internal stage description alone is not a useful notice.
+- When several files fail, issue one concise summary notice after the operation returns. Keep the per-file paths and technical causes at verbose level so that the notice remains readable and the generated report remains traceable.
+- Commonlib should raise a notice only when its contract explicitly owns user presentation and no higher-level caller can add the required workflow context.
+
+The ordinary start-up scan provides a concrete comparison:
+
+- Good verbose diagnostic: `Offline scan failed to synchronise ${path} between storage and the local database; this path remains eligible for a later scan.` It identifies the operation, the two states being reconciled, the exact target, and what can happen next. Its length is appropriate for a report.
+- Notice which needs more context: `Local database initialisation did not complete. See the log for details.` It describes an internal stage, but does not tell the user whether synchronisation can continue, what may be affected, or how to obtain the detailed log.
+- Good application notice for a partial result: `Not all files could be synchronised. Check the affected files. Generate a report to review the detailed log.` It states the observable consequence, gives a proportionate action, and leaves the per-file evidence in the report.
+- Good application notice for a failed result: `Self-hosted LiveSync cannot synchronise. Generate a report to review the detailed log.` It states the operational consequence without exposing the internal initialisation stage.

 ### Flag-file recovery order
 
 - For a configured Vault, evaluate and persist the compatibility gate after settings load, before Obsidian layout-ready recovery begins. This blocks ordinary and one-shot replication even while the review dialogue has not yet opened. An existing unconfigured Vault follows the deferred rule above instead.
+- Admit configured-only start-up work at priority 1, after ordinary priority-0 layout integration and before flag-file recovery. An unconfigured Vault offers onboarding and returns `false`, so recovery, compatibility review, database preparation, and configured-only request handling do not run. Treat this admission as a property of the current plug-in process: changing `isConfigured` from `false` to `true` requires the scheduled restart before configured work becomes available, and declining that restart deliberately leaves the current process inert. If an admitted process changes `isConfigured` to `false`, retire the Config Doctor and incomplete-document repair request handlers immediately, and recheck the current setting and database readiness when either handler runs.
 - Preserve the existing ordered flag-file recovery handlers: SCRAM at priority 5, fetch-all at priority 10, and rebuild-all at priority 20. These files express an explicit recovery instruction and may invoke their focused storage or rebuild service while ordinary replication remains gated.
 - Present the compatibility review at priority 30, after any selected recovery operation. A recovery handler which cancels start-up, keeps SCRAM active, or schedules a restart returns `false`, so the current process does not open a competing compatibility dialogue. If recovery completes and start-up continues, the dialogue opens before normal synchronisation is allowed to resume.
 - Keep database preparation independent of an unanswered compatibility dialogue, because the compatibility gate already blocks replication. Before Config Doctor begins its interactive checks, await the active initial review so that the two update dialogues cannot overlap.

+# Path component length compatibility
+
+## Purpose
+
+File systems place limits on each file or folder name, rather than applying one
+common limit to an entire Vault-relative path. Those limits are also expressed
+in different units. Self-hosted LiveSync therefore treats 255 UTF-8 bytes as a
+focused Android and Linux compatibility warning, not as a universal definition
+of a valid path.
+
+## Basis for the 255-byte warning
+
+- The Linux kernel documentation gives ext4 a maximum file-name length of
+  [255 bytes](https://www.kernel.org/doc/html/latest/filesystems/ext4/directory.html).
+- The F2FS on-disk header defines
+  [`F2FS_NAME_LEN` as 255](https://android.googlesource.com/kernel/common/+/88d92fb1c034922572bab93482ac9cc61d4ba43c/include/linux/f2fs_fs.h)
+  and stores names in byte arrays.
+- Android's MediaProvider uses a
+  [`MAX_FILENAME_BYTES` value of 255](https://android.googlesource.com/platform/packages/providers/MediaProvider/+/bae279463/src/com/android/providers/media/util/FileUtils.java)
+  when building file names. Its source notes that emulated storage can write to
+  ext4 through FUSE, where names are encoded as UTF-8.
+- Android 11 and later use
+  [FUSE for emulated storage](https://source.android.com/docs/core/storage/fuse-passthrough),
+  with requests passing through to the underlying file system.
+
+Together, these provide a conservative compatibility boundary for file names
+which may reach Android or Linux storage. They do not show that every Android
+device, storage provider, or Linux file system has the same limit.
+
+## Why the rule is not universal
+
+Other platforms describe component limits differently. Microsoft's file-system
+comparison documents limits in
+[Unicode characters](https://learn.microsoft.com/en-us/windows/win32/fileio/filesystem-functionality-comparison),
+not UTF-8 bytes. Apple's HFS Plus format stores a name as up to
+[255 16-bit `UniChar` values](https://developer.apple.com/library/archive/technotes/tn/tn1150.html).
+Apple's APFS guidance discusses valid UTF-8 names, normalisation, and case
+sensitivity, but does not establish a universal
+[255-byte component rule](https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/APFS_Guide/FAQ/FAQ.html).
+
+A name can consequently exceed 255 UTF-8 bytes and still work on one platform,
+or fail for another platform-specific reason while remaining below this
+boundary.
+
+## Product policy
+
+Self-hosted LiveSync applies the warning as follows:
+
+1. split the Vault-relative path on `/` and inspect each non-empty component;
+2. measure each component after UTF-8 encoding;
+3. accept 255 bytes without this warning and warn at 256 bytes or more;
+4. identify every over-limit file or folder name in the active-file status;
+5. do not reject, truncate, or rename the path; and
+6. treat the result of the real storage operation as authoritative.
+
+If a scan cannot process an individual file, its path is recorded in the
+verbose log and remains eligible for a later retry. Ordinary start-up may still
+become ready so that unaffected files can synchronise. Explicit Fetch and
+Rebuild operations retain strict scan completion because they establish an
+authoritative local or remote state.
+
+This policy does not replace the existing checks for reserved characters,
+case collisions, ignore rules, or configured file-size limits.

+### Ordered start-up composition and registration-only features
+
+Configured Vault admission and the checks which follow database preparation are composed by `src/serviceFeatures/startupLifecycle/`. The directory keeps onboarding admission, compromised-chunk inspection, incomplete-document repair, Config Doctor, and the obsolete bulk-send setting migration as separate operations. One feature composer owns their order and receives the compatibility-review wait operation explicitly; an individual operation does not call the composer.
+
+The layout-ready admission handler uses priority 1. This preserves ordinary priority-0 host integration before admission, while keeping an unconfigured Vault outside the flag-file recovery handlers at priorities 5, 10, and 20, and the compatibility review at priority 30. Admission belongs to one plug-in process: an initially unconfigured process remains inert until setup restarts it, and declining the requested restart does not trigger an in-process reconfiguration. Changing an admitted process back to unconfigured retires its Config Doctor and incomplete-document repair request handlers. The handlers also recheck the current configured state and database readiness when invoked, so a pending restart cannot expose partially initialised or retired state. The first-initialise handler rechecks admission before retaining the established order after the file watcher has been started: database readiness, compromised chunks, incomplete documents, compatibility review, Config Doctor, and the bulk-send setting migration.
+
+Command and ribbon registration are serviceFeatures for the same dependency-visibility reason, but they are not start-up migrations. The basic commands remain a host-neutral feature composed by `LiveSyncBaseCore`, while the replication ribbon remains an Obsidian-only feature composed by the Obsidian host. Both retain `onInitialise` registration so moving them out of the Module list does not make their effects run during construction.
+
 ### Private state and ordered handlers: target filters
 
 Commonlib's `targetFilter.ts` keeps each cache or readiness gate in the factory which owns one predicate. `useTargetFilters()` constructs those predicates and registers them in their required order.
 
 The state remains private to the composed feature. It does not become a `LiveSyncBaseCore` property or a ServiceModule merely because it persists across calls.
 
-### Legacy example to improve when touched: conflict checking
+### Implemented composition: conflict resolution
 
-`ModuleConflictChecker` currently combines:
+Conflict checking and resolution are composed for every host by `useConflictResolutionFeature`. The feature owns its `QueueProcessor` privately and registers the conflict Service handlers directly. Its operations receive explicit collaborators for settings, active-file state, database and storage access, replication, logging, and host events. No consumer locates a conflict Module or retains the queue.
 
-- conflict policy decisions;
-- two `QueueProcessor` owners;
-- cancellation signalling;
-- access to settings and active-file state; and
-- registration into the conflict Service.
+The scheduling queue remains one state owner. It publishes `conflictProcessQueueCount`, coalesces pending checks for the same path, and makes `ensureAllProcessed()` wait for conflict resolution to finish. Repeated resolver invocations for one path retain only the newest waiting request and close an active comparison for that path before waiting for the per-file resolver, while comparisons for other paths remain open. Resolution remains host-neutral and communicates dialogue cancellation through `services.context.events`, so CLI, WebApp, and Obsidian compositions use their own selected event channel.
 
-Its queues are class fields which dereference `this.services` during field initialisation, and its public handlers are bound later in `onBindFunction()`.
+Interactive resolution is a separate Obsidian-owned serviceFeature. It registers the manual conflict handler, commands, start-up scan, unresolved-message contribution, cancellation listener, and unload clean-up. Its postponed-conflict set, active dialogue, and dialogue queue are private, session-local state. Manual comparisons are shown one at a time: a request for the active file publishes `EVENT_CONFLICT_CANCELLED` to cancel and replace its dialogue, while a request for another file waits. A resolution received through replication closes an open dialogue for the resolved path through the same event, or discards its waiting request before a stale dialogue can open. On unload, the feature drops waiting requests and publishes the same event for the active path before the host event channel is retired, so the dialogue closes and its waiting operation completes. The feature receives a dialogue-opening adapter and connects to the common feature only through the conflict Service; it does not expose an Obsidian application or dialogue as a general capability.
 
-A bounded change to this area should prefer a shape such as:
+Both operation layers acquire the active local database through an operation-time accessor. Composition occurs before the database is opened, and a reset may replace the active instance, so retaining the database object at composition time would violate both start-up and reset boundaries.
 
-```typescript
-interface ConflictCheckContext {
-    readonly checkQueue: QueueProcessor<FilePathWithPrefix, unknown>;
-    readonly resolveQueue: QueueProcessor<FilePathWithPrefix, unknown>;
-}
-
-interface ConflictCheckDependencies {
-    readonly conflict: ConflictCapability;
-    readonly currentSettings: () => ConflictSettings;
-    readonly getActiveFilePath: () => FilePathWithPrefix | undefined;
-    readonly log: LogFunction;
-}
-
-function queueConflictCheck(
-    context: ConflictCheckContext,
-    dependencies: ConflictCheckDependencies,
-    path: FilePathWithPrefix
-): Promise<void> {
-    // Make the decision and enqueue through explicit collaborators.
-}
-
-export function useConflictChecking(host: ConflictCheckingHost): void {
-    const context = createConflictCheckContext(host);
-    host.services.conflict.queueCheckFor.setHandler((path) => queueConflictCheck(context, dependencies, path));
-}
-```
-
-The exact extraction should be made only when conflict-checking behaviour changes. The example describes the intended ownership boundary; it is not a request to convert the Module in an unrelated documentation change.
+`ConflictResolveModal` remains a focused class. One instance owns one dialogue's result promise, event subscription, and close lifetime, which is stable identity and resource ownership rather than application composition. This preserves the distinction between a useful object lifetime and a legacy Module used as a service locator.

Beta and release-candidate builds published before 1.0.0 are recorded in the [1.0 preview history](1.0-previews.md). Earlier release lines continue in the [0.25 history](0.25.md) and the [legacy history](legacy.md).
 
+## 1.0.21
+
+26th August, 2026
+
+It is becoming more 'ordinary' with each release, but please let me know if anything has become less convenient.
+
+### Interface and translation
+
+#### Fixed
+
+- Remote Configuration section headings no longer overlap their contents when scrolling on mobile. Action buttons in Remote Configuration, Maintenance, and Patches now remain inside the settings pane on narrow screens.
+
+## 1.0.20
+
+~~1.0.19~~ was cancelled because prerelease validation exposed an incorrect warning at start-up.
+
+25th August, 2026
+
+I know this is the second time I have said it, but I had grown quite fond of the settings screen. It seems, however, that a simpler, healthier life is called for.
+
+### Interface and translation
+
+#### Fixed
+
+- Compatibility pause warnings now direct you to the dedicated compatibility review instead of the Change Log.
+- The Obsidian 1.13 settings page now waits for saved settings before choosing its initial layout. This prevents a spurious missing-replicator warning at start-up, keeps configured devices on the Synchronisation-first layout even when automatic synchronisation triggers are disabled, and keeps Quick Setup first on unconfigured devices.
+
+#### Improved
+
+- Settings page names, controls in General Settings, Quick Setup actions, and Advanced controls now use Obsidian 1.13's native settings interface and global search, while retaining their familiar icons. The landing page keeps Remote Configuration and Sync Settings together, places Appearance, Logging, and Extra menus under General Settings, and groups maintenance, optional features, advanced settings, and help by purpose. Earlier supported Obsidian versions continue to use the pane-based interface.
+- Settings changes which require database initialisation now use a focused Setup Manager dialogue to choose between existing synchronisation data and the files in the current Vault. The selected reset or rebuild is reserved before the settings are saved, while cancelling offers a separate, explicit settings-only fallback.
+
+## 1.0.18
+
+24th August, 2026
+
+### Synchronisation and storage
+
+#### Fixed
+
+- Reset and rebuild workflows now use the local database selected by their updated settings, preventing stale data from reopening after a **Database Suffix** change. If database initialisation does not complete, the workflow remains paused instead of continuing with incomplete state.
+
+#### Improved
+
+- Rebuilds now recheck restored file events against the current Vault, use current file contents, and finish processing them before the plug-in reports readiness.
+
+## 1.0.17
+
+23rd August, 2026
+
+### Interface and translation
+
+#### Fixed
+
+- Settings generated from the settings manifest, Setup Wizard configuration summaries, and warnings about externally changed settings now honour **Display language** when a translation is available, instead of remaining in English (PR #1123). Thank you to @nimula for the contribution!
+
+### Peer-to-peer synchronisation
+
+#### Improved
+
+- P2P connection profiles now provide four **P2P message size** presets and a **Connection path** choice between **Automatic** and **TURN relay only**. Smaller messages can improve compatibility on paths which fragment or drop larger WebRTC messages, while relay-only routing requires a configured TURN server. P2P connection strings and encrypted Setup URIs preserve both choices.
+    - Thank you to @andrewschreiber for the detailed fragmentation diagnosis and working 800-byte threshold in vrtmrz/livesync-commonlib#97, which informed this compatibility design.
+- An optional self-hosted Coturn Compose starter is now available for P2P deployments that need a TURN relay. It uses a pinned upstream image and documents its network, credential, security, and verification boundaries.
+
+## 1.0.16
+
+19th August, 2026
+
+### Conflict handling and recovery
+
+#### Fixed
+
+- **Back to this revision** in Document History now restores the selected content as a new non-deleted successor revision before reflecting it to the Vault. A readable revision restored after a logical deletion therefore remains restored through later synchronisation instead of being overwritten by the deletion.
+    - If the file changes while restoration is in progress, the operation stops instead of extending a stale revision. Existing conflicts remain available through **Inspect conflicts and file/database differences**.
+
+### Synchronisation and storage
+
+#### Improved
+
+- One-shot CouchDB synchronisation now releases stalled web-compatible connection checks before replication starts, so a later synchronisation can make a fresh attempt (Commonlib 0.1.16).
+    - The 60-second safeguard applies only to pre-replication checks. It does not limit ordinary synchronisation, and the **Use Internal API** path is unchanged.

+## File events and storage writes
+
+File events describe changes observed in the Vault. Commonlib filters and
+serialises those events before updating file Metadata in the local database.
+A queued `DELETE` therefore requests a database change; it is not itself an
+instruction to delete the physical file. A rename out of the selected files
+can also become a database deletion while the destination remains on disk.
+
+The opposite direction starts with database Metadata. Replicated changes and

+Vault files subject to its conflict and content-preservation rules. Preventing
+a stale file event from deleting Metadata and applying a valid replicated
+deletion are separate decisions.

+# Summary
+
+Self-hosted LiveSync は、ローカルの Markdown ファイルとして文書を保存するノートアプリ Obsidian [@obsidian] 向けのオープンソース同期プラグインである。ユーザーが管理するストレージまたは直接のピアツーピア接続を介し、ノートや添付ファイルを収めたディレクトリー（Vault）をデスクトップとモバイルデバイス間で同期する。
+
+本プラグインにより、ユーザーはオフラインで編集を行い、再接続後に同期できる。2台のオフライン端末で同一ノートを別々に編集した場合のように編集の衝突が生じても、即座の解決を強制したり競合する変更を無条件に上書きしたりすることはない。ファイル形式や設定されたポリシーに応じて、重複しない変更箇所の自動マージや、競合する版を後から比較・解決するための保持が可能である。組み込みの検査ツールは、競合や内容の欠落の調査を支援し、コピーが残っている場合の復旧を支援する。
+
+本ソフトウエアは、データの保存先を自ら管理しながら複数デバイスで記録を継続する必要がある研究者、エンジニア、および実務者のワークフローに対応する。
+
+# Statement of Need
+
+研究やエンジニアリングのワークフローは、長期間蓄積されるノート、観察記録、設計上の決定事項、および関連ファイルに依存している。著者の業務では、管理下にある各デバイスの導入ソフトウエアを制御し、業務ファイルを自身の管理下にあるインフラで扱い、運用実績のあるサーバーソフトウエアを採用する必要があった。これらの制約から、デスクトップとモバイル双方の Obsidian 内で直接動作し、外部クライアントデーモンを必要としない同期エンジンを開発した。
+
+オフライン端末で別々に行った編集の競合は、変更を交換した際に認識される。意図しない編集や削除、並行した変更の乖離、あるいはデータベースの状態とは独立した外部ツールによるファイル変更も起こりうる。競合する版を保持せずに単一の版で上書きしてしまうと、ユーザーが変更を確認して判断する前に情報が失われるおそれがある。
+
+フィールドワークやモバイルでの作業中、研究者や実務者は、競合する編集内容をレビューする前であっても、観察の記録とデバイス間でのノート転送を続ける必要がある。Self-hosted LiveSync は、このように記録と競合解決を分けて進める作業を支援する。並行ブランチが未解決のままでも複製を継続でき、競合する編集は、レビューまたは設定されたポリシーによって解決されるまで保護される。
+
+# State of the Field
+
+ローカルファーストソフトウエアは、ユーザーデータの唯一の所有者としてのホスト型サービスへの依存を避けつつ、ローカルにおける可用性と、複数デバイス間での同期や協調を両立させる [@kleppmann2019localfirst]。Obsidian エコシステム内では、いくつかのツールが異なるアプローチから複数デバイス間の同期に対応している。Obsidian Sync は統合されたホスト型サービスを提供し [@obsidiansync]、Obsidian Git はバージョン管理指向の push/pull ワークフローを提供し [@obsidiangit]、Syncthing はファイルシステム層で動作し [@syncthing]、Remotely Save はクラウドやセルフホスト型ストレージの複数の API に Obsidian を接続する [@remotelysave]。
+
+これらのアプローチは、並行する変更の表現方法が異なる。Syncthing は競合コピーを通常のファイルとして他のデバイスへ転送し [@syncthingsync]、Git は分岐した履歴をマージ前に取得できる [@gitfetch]。Obsidian Git はデスクトップおよびモバイル上でこの操作を自動化している [@obsidiangit]。Conflict-free Replicated Data Types（CRDT）でも複数の選択肢を検査でき、Automerge は同じオブジェクトプロパティーへの並行した代入を保持する [@automergeconflicts]。Self-hosted LiveSync は、競合するファイルの各バージョンを、メタデータドキュメントのリビジョンツリー上の末端リビジョン（leaf、各分岐の現在の版）として保持し、設定されたポリシーまたはユーザーによる明示的な操作によって解決されるまで維持する。
+
+これらの既存ツールはそれぞれ異なる運用上の要請に応えている。ホスト型サービスは導入の平易さを重視し、外部のファイル同期ツールは任意のファイルシステムツリーを対象とし、バージョン管理ツールは明示的なコミットワークフローを前提としている。一方、著者の環境では管理対象デバイス上でバックグラウンドクライアントデーモンの実行が制限されており、かつ競合する版の保持と、その版に結び付いたファイル更新を扱うためには、複製処理とローカルファイル操作を直接統合する必要があった。そのため、Self-hosted LiveSync は外部デーモンを介さず Obsidian 内で直接動作するプラグインとして構築され、複数のバックエンドで同一のリビジョンセマンティクスを維持するために、中核ロジックをプラットホーム非依存のエンジンとして分離する構成が採用された。
+
+Self-hosted LiveSync は新しいデータベース複製アルゴリズムを導入するものではない。むしろその貢献は、リビジョン認識可能なデータベースのセマンティクスを、外部から編集できるファイル Vault へ適用した点にある。Content-addressed なチャンク、デバイスローカルな来歴情報、および組み込みの復旧ツールにより、通常のノート作成ワークフローを損なうことなく、競合のレビューを保留しながら編集を継続できるようにしている。
+
+# Software Design
+
+共通の複製サービスおよび競合処理サービスは `@vrtmrz/livesync-commonlib` [@commonlib021] として公開されており、Obsidian プラグイン、コマンドラインインターフェース（CLI）、Web アプリケーション、および Web Peer で利用されている。
+
+## Revision-aware Vault representation
+
+Vault の各ファイルは、ローカルの PouchDB [@pouchdb] 内で、パス、サイズ、更新日時、および分割されたチャンクドキュメントへの参照を含むメタデータドキュメントとして表現される。チャンクは Content-addressed であり、同一のコンテンツ領域を持つリビジョン間や異なるファイル間で再利用できる。複数デバイス間で並行して更新が行われると、メタデータドキュメントの周囲に競合する複数の leaf（子を持たない末端リビジョン）が形成される。PouchDB はデフォルトの取得対象として決定論的な winner（選出された leaf）を選出するが、この選択は内部的なタイブレークに過ぎず、その winner がより新しい、より安全である、あるいは特定のデバイスの Vault に表示されているバージョンであることを証明するものではない。
+
+並行する更新によってブランチ $\alpha$ と $\beta$ に分岐した場合、両方の leaf は解決前に他のデバイスへ複製される。自動3方向マージは、両方の leaf と最も近い利用可能な共通祖先についてメタデータ本文およびチャンクが読み取り可能である場合に、Markdown（`.md`）、Canvas（`.canvas`）、および JSON（`.json`）ファイルを対象として適用される（その他の形式は対象外である）。Markdown では、同一オフセットへの並行した挿入は即座に失敗とせず、更新日時に応じて順次連結して統合できる。CouchDB の複製プロトコルは祖先リビジョンの識別子を伝播するものの祖先の内容は取得しないため [@couchdbreplication]、祖先の履歴や内容が欠落している場合、あるいは互換性のない編集衝突が生じた場合、同期エンジンは自動マージを保留する。自動マージが無効または適用不能であり両方の版が読み取り可能である場合、JSON ファイルおよび内容の異なるバイナリーファイルは互換性のための動作として、「常に新しいファイルで上書きする」が無効であっても更新日時によって解決され、このオプションを有効にするとテキストの競合にも当該解決が拡張される。それ以外の場合、テキストの競合は手動解決のために保持され、両方の版が読み取り可能であれば2方向の差分（two-way diff）によって直接比較できる。
+
+## Device-local branch provenance
+
+データベースは競合する複数のブランチを同時に保持できるが、ローカルの Vault は任意のパスに対して単一の実体ファイルしか配置できない。ローカルファイルがどのブランチを表しているかを識別するため、本プラグインは正確なデータベースリビジョンと観測されたローカルの更新日時をデバイスローカルな Key-Value ストアに保存する。このリビジョンは当該パスの**ブランチアンカー**として機能し、データベースから Vault への実体化、または Vault からデータベースへの書き込みが成功した後に更新される。
+
+未解決の競合が存在する状態において、ローカルで行われた編集や論理削除はアンカーされたリビジョンの子となり、競合する leaf を損なうことなく、その特定のブランチを前進させる。パスをまたぐリネームでは、移動先を保存した上で、アンカーされた移動元のブランチのみを論理削除する。この状態で来歴情報が利用できない場合、本プラグインはファイルのバイト列が利用可能な既存の単一リビジョン本文と厳密に一致する場合に限り Vault 内のファイルをそのリビジョンにひもづけ、それ以外の場合はパスや日時から勝手に推測せず、手動解決すべき競合として保持する。競合が存在しない通常時は、通常の書き込みによって単に現在のデータベースリビジョンが前進する。
+
+組み込みのコンフリクトインスペクターは、現在の winner、すべての conflict leaf、および最も近い利用可能な共通祖先を検査する。インスペクターは欠落したチャンクやファイル／データベース間の差異を報告し、現在の leaf を明示的に選択して操作できるようにする。変更を伴う操作は実行前にリビジョンを再確認し、古い画面状態によってすでに末端ではなくなったリビジョンを誤って削除したり前進させたりするのを防止する。
+
+## Transport-independent replication
+
+CouchDB のリビジョンモデルを基準に、Self-hosted LiveSync はデータベースの表現を通信トランスポートから分離し、バックエンドにかかわらずファイルメタデータのリビジョン識別子と競合する leaf をそのまま複製する。CouchDB [@couchdb] ではネイティブなリビジョン複製を利用する。S3 互換オブジェクトストレージでは、メタデータドキュメントの末端リビジョンと祖先リビジョンの識別子をジャーナルに記録し、新しいローカルリビジョンを作成せずに適用する一方、チャンクドキュメントは内容由来の識別子を保持し、新しいローカルリビジョンとして保存される。WebRTC ピアツーピア（P2P）アダプター [@webrtc] は、Trystero [@trystero] の DataChannels と RPC ベースのレプリケーション shim によりドキュメント要求をバッチ処理し、同一のリビジョンセマンティクスをピア間で直接保持する。CouchDB およびジャーナル転送においては、Web Streams が転送をパイプライン処理し、転送中にメモリーへ保持されるデータ量を抑制する。
+
+これらのトランスポートは柔軟に組み合わせられる。P2P 同期は参加デバイスが同時にオンラインである必要があるが、中央の CouchDB やオブジェクトストレージを併用することで、オフライン期間を挟んだデバイス間でも同期できる。すべての通信方式でコンテンツのエンドツーエンド暗号化とパス難読化をサポートしている。P2P では接続交渉時のセッション記述が暗号化されるが、シグナリングリレーやネットワークサービスからは接続時刻やネットワークアドレスを観測できる。
+
+## Retention and recovery
+
+分岐した各ブランチは未変更のチャンクを共有するため、競合する leaf を保持するために生じるコストは主に新規チャンクとリビジョンメタデータに限られる。蓄積した保存領域はリモートデータベースの再構築によって回収できるほか、CouchDB 向けには、明示的に開始するベータ版のガベージコレクションにより、現在の winner、すべての conflict leaf、および未解決の競合を検査するために必要な、利用可能な祖先から到達可能なチャンクを保護しながらインプレースで回収できる。過去のリビジョンで置き換えられたチャンクは後から回収されうるため、過去のリビジョン本文は無条件のバックアップではない。
+
+必要なチャンクが欠落している場合でも、読み取り不能な現在のリビジョンはリビジョンツリーに残り、競合処理によって自動的に破棄されることはない。欠落したチャンクが他のデバイスに残っている場合があるため、それらの再接続と同期を待って復旧操作を保留できる。競合インスペクターは影響を受けるリビジョンを明示し、取得の再試行や明示的な復旧操作を支援する。復旧には、デバイス、リモートストレージ、またはバックアップに内容が残っている必要がある。
+
+# Research Impact Statement
+
+Self-hosted LiveSync は、著者が複数のデバイスやプラットホームを対象に行うソフトウエア開発業務から生まれた。この作業では、主たるデバイスを利用できない状況でも、各デバイスでスクリーンショットを取得し、観察記録を保存する必要があった。同じワークフローは、現在では著者の先行技術調査にも利用されており、先行文献の読解に伴うメモや考察を同期するために用いられている。競合する版が保持されることで、分岐した記録が即座に上書きされず、後から比較・確認することが可能になる。
+
+ユニットテストおよび結合テストは、リビジョンの系譜、チャンクの到達可能性、利用できない内容、およびホストの構成を対象とする。CLI および実環境の Obsidian によるシナリオでは、競合する leaf が残っている状態での編集、論理削除、およびリネームを含め、競合の伝播と解決を検証する。3ノードの P2P シナリオでは、未解決の leaf が解決前にデバイス間を移動できることを確認している。再利用可能なヘッドレステスト基盤は独立してアーカイブされている [@fancykit]。決定論的なフィクスチャーを用いて同一の生成データ上で P2P と CouchDB の経路を比較しているが、制御されたローカル測定値が普遍的な性能を示すわけではない。
+
+2026年9月2日時点で、Obsidian プラグインディレクトリーでは 90万回以上のダウンロード、デスクトップおよびモバイルのサポート、ならびに公式の Research カテゴリーへの配置が報告されている [@obsidianplugin]。GitHub リポジトリーでは 12,200件以上のスター、440件のフォーク、および広範なユーザーコミュニティーからの貢献が記録されている [@selfhostedlivesyncrepo]。これらの数値自体は研究上の直接的な影響を証明するものではないが、本ソフトウエアがコミュニティーに受容され、単一のプライベートなワークフローを超えて運用されている証拠を提供する。
+

+# Summary
+
+Self-hosted LiveSync is an open-source synchronisation plug-in for Obsidian [@obsidian], a note-taking application that stores documents as local Markdown files. It replicates a user's vault—a directory containing notes and attachments—across desktop and mobile devices using user-controlled storage or direct peer-to-peer connections.
+
+The plug-in allows users to continue editing offline and synchronise upon reconnection, even when conflicting edits arise—such as when two disconnected devices modify the same note concurrently. Rather than forcing immediate reconciliation or unconditionally overwriting competing changes, the system supports automatic merging of non-overlapping edits and preserves competing versions for deferred review, depending on file formats and configured policies. Built-in inspection tools help users investigate conflicts or missing content and recover files when surviving copies exist.
+
+The software serves researchers, engineers, and practitioners who require continued note-taking across multiple devices while controlling their data storage.
+
+# Statement of Need
+
+Research and engineering workflows depend on long-lived notes, observations, design decisions, and supporting files. The author's work required managing the software installed on each device, keeping files on infrastructure under personal control, and using server software with an established operational record. These constraints motivated a synchronisation engine running directly inside Obsidian across desktop and mobile platforms without external client daemons.
+
+Conflicts arising from concurrent edits on disconnected devices are recognised only after devices exchange updates. An edit or deletion may be unintended, concurrent modifications may diverge, or external tools may update files independently of database events. Overwriting with a single version without retaining competing revisions risks irreversibly discarding information before users can evaluate the divergence.
+
+During fieldwork and mobile operations, researchers and practitioners often need to continue recording observations and transferring notes between devices before reviewing competing edits. Self-hosted LiveSync supports this separation of recording and reconciliation: replication proceeds while concurrent branches remain unresolved, protecting competing edits until they can be reviewed or resolved according to configured policies.
+
+# State of the Field
+
+Local-first software combines local availability with multi-device synchronisation and collaboration while avoiding dependence on a hosted service as the sole owner of user data [@kleppmann2019localfirst]. Within the Obsidian ecosystem, Obsidian Sync provides an integrated hosted service [@obsidiansync]; Obsidian Git provides version-control-oriented push and pull workflows [@obsidiangit]; Syncthing operates at the filesystem layer [@syncthing]; and Remotely Save connects Obsidian to several cloud and self-hosted storage APIs [@remotelysave].
+
+These approaches differ in how they represent concurrent changes. Syncthing propagates conflict copies as ordinary files [@syncthingsync], while Git can fetch divergent histories into separate tracking branches before merging them [@gitfetch], an approach automated on desktop and mobile by Obsidian Git [@obsidiangit]. Conflict-free replicated data types (CRDTs) can also expose alternatives: Automerge retains concurrent assignments to an object property for inspection [@automergeconflicts]. Self-hosted LiveSync retains competing file versions as leaves—the current versions of divergent branches—in the metadata document's revision tree until resolved by configured policies or explicit user action.
+
+These existing tools address distinct operational needs: hosted services prioritise turnkey convenience, external file synchronisers manage arbitrary filesystem trees, and version-control tools introduce explicit commit workflows. In the author's environment, however, managed devices prohibited background client daemons, while retaining competing revisions alongside their associated file updates required integrating replication directly with local file operations. Self-hosted LiveSync was therefore implemented as an Obsidian plug-in running entirely within the application runtime, backed by a decoupled, platform-independent engine to maintain uniform revision semantics across backends.
+
+Self-hosted LiveSync does not introduce a new database replication algorithm; rather, its contribution lies in applying revision-aware database semantics to an externally editable file vault. Content-addressed chunks, device-local branch provenance, and built-in recovery tools support continued editing while conflict review is deferred, protecting divergent work without altering standard note-taking workflows.
+
+# Software Design
+
+The shared replication and conflict-handling services are published as `@vrtmrz/livesync-commonlib` [@commonlib021] and used by the Obsidian plug-in, command-line interface (CLI), web application, and web peer.
+
+## Revision-aware Vault representation
+
+Each Vault file is represented in local PouchDB [@pouchdb] by a metadata document containing its path, size, modification time, and references to separate chunk documents. Chunks are content-addressed and can therefore be reused across revisions and files with identical content regions. When concurrent updates occur across devices, they form multiple competing leaves around the metadata document. PouchDB selects a deterministic winner for default retrieval, but this choice is an internal tie-breaker rather than evidence that the winner is newer, safer, or the version represented by a particular device's Vault.
+
+When concurrent updates diverge into branches $\alpha$ and $\beta$, both leaves replicate to other devices before resolution. Automatic three-way merging applies to Markdown (`.md`), Canvas (`.canvas`), and JSON (`.json`) files when both leaves and their nearest available shared ancestor are readable; other formats are excluded. In Markdown, concurrent insertions at the same offset concatenate sequentially by modification time. Because CouchDB replication transfers ancestry identifiers without ancestor content [@couchdbreplication], missing ancestral history or conflicting edits defer automatic merging. When automatic merging is disabled or inapplicable and both versions are readable, JSON and differing binary files resolve by modification time as a compatibility fallback, even when 'Always overwrite with a newer file' is disabled; enabling that option extends modification-time resolution to text conflicts. Otherwise, competing text versions remain for manual resolution, and can be compared via a two-way diff when both leaves are readable.
+
+## Device-local branch provenance
+
+While the database can retain competing branches concurrently, a local Vault can instantiate only a single concrete file at any given path. To resolve which branch a local file represents, the plug-in stores an exact database revision and observed local modification time in a device-local key-value store. This revision serves as the path's **branch anchor**, updated after a successful database-to-Vault reflection or Vault-to-database write.
+
+During active conflicts, local edits or logical deletions become children of the anchored revision, advancing that branch while keeping competing leaves intact. Cross-path renames store the target before logically deleting only the anchored source branch. If provenance is unavailable, the plug-in binds a file to an existing revision only when its bytes match exactly one available revision body; otherwise, it retains the conflict for manual resolution rather than guessing from paths or timestamps. Without active conflicts, ordinary writes simply advance the database revision.
+
+The built-in conflict inspector examines the current winner, every conflict leaf, and the nearest available shared ancestor. It reports missing chunks and file/database differences, permitting operations on an explicitly selected current leaf. Mutating operations recheck the revision beforehand, preventing a stale inspection from deleting or extending a superseded branch.
+
+## Transport-independent replication
+
+Using CouchDB's revision model as a baseline, Self-hosted LiveSync decouples database representation from network transport, replicating file-metadata revision identifiers and competing leaves intact across backends. CouchDB [@couchdb] provides native revision-aware replication. S3-compatible storage journals metadata leaf revisions and ancestry identifiers without synthesising new revisions, while chunk documents are stored as new local revisions with content-derived identifiers. The WebRTC peer-to-peer (P2P) adapter [@webrtc] uses Trystero [@trystero] DataChannels and an RPC-based replication shim to batch document requests while preserving identical revision semantics directly between peers. In CouchDB and journal transfers, Web Streams pipeline data to limit the amount of data buffered in memory during transfer.
+
+Transports combine flexibly: while P2P requires concurrent online presence, pairing it with CouchDB or object storage bridges offline intervals. All transports support end-to-end content encryption and path obfuscation. P2P encrypts session descriptions during connection negotiation, though signalling relays and network services can still observe connection timing and network addresses.
+
+## Retention and recovery
+
+Because alternative branches share unchanged chunks, retaining competing leaves incurs storage and transfer costs primarily for new chunks and revision metadata. Remote database rebuilds reclaim space, while an explicitly initiated beta garbage-collection workflow provides in-place CouchDB cleanup by protecting chunks reachable from the current winner, every conflict leaf, and the available ancestry needed to inspect active conflicts. Because superseded chunks may be collected, historical revisions are not an unconditional backup.
+
+When chunks are missing, unreadable current revisions remain in the tree rather than being automatically discarded during conflict processing. Because missing chunks may still exist on other devices, users can defer recovery until they reconnect and synchronise. The conflict inspector identifies affected revisions and facilitates retrieval retries and explicit recovery actions. Recovery ultimately requires surviving content on a device, in remote storage, or in a backup.
+
+# Research Impact Statement
+
+Self-hosted LiveSync originated in the author's multi-platform software engineering workflows, capturing screenshots and recording observations across multiple devices, including when a primary device was unavailable. Today, the same workflow supports the author's patent prior-art investigations, synchronising notes and reflections made while reading prior patent literature. Retaining competing revisions allows divergent observations to be compared after the fact rather than overwritten immediately.
+
+Unit and integration tests cover revision ancestry, chunk reachability, unavailable content, and host composition. CLI and real-Obsidian scenarios exercise conflict propagation and resolution, including edits, logical deletions, and renames while competing leaves remain active. A three-node P2P scenario verifies that unresolved leaves move between devices before resolution. Reusable headless test infrastructure is archived independently [@fancykit]. Deterministic fixtures compare P2P and CouchDB paths over identical generated data; controlled local measurements do not establish universal performance.

+As of 2 September 2026, the Obsidian plug-in directory reported more than 900,000 downloads, desktop and mobile support, and placement in its Research category [@obsidianplugin]. The GitHub repository recorded over 12,200 stars, 440 forks, and contributions from a broad user community [@selfhostedlivesyncrepo]. These figures demonstrate community adoption rather than direct research impact, but they provide evidence that the software operates beyond a single private workflow.
+
+The software described here is Self-hosted LiveSync 1.0.23 [@selfhostedlivesync], released under the MIT licence and pinned to Commonlib 0.1.21 [@commonlib021]. Zenodo archives the plug-in, the reusable test harness [@fancykit], and an earlier Commonlib 0.1.19 snapshot [@commonlib]. Platform-independent logic supports independent testing and reuse.

 `test:e2e:obsidian:startup-scan` starts from a CouchDB fixture using current settings with its device-local compatibility marker already acknowledged, stops Obsidian, writes a note directly into the Vault, restarts the same isolated Vault and profile without rewriting its plug-in data, and verifies from CouchDB that the start-up scan picked up the offline file. Onboarding remains covered by `onboarding-invitation`; this scenario owns the ordinary configured restart and start-up scan.
 
+`test:e2e:obsidian:partial-startup-file-failure` is a focused Linux release-acceptance scenario for an ordinary configured restart. It stores one valid database-only note and one database-only note whose path component is 258 UTF-8 bytes, then restarts the same isolated Vault and profile. On a Linux test Vault which enforces the conventional 255-byte component limit, the scenario requires the valid file to be reflected, the application to become ready, the partial-failure Notice to appear, and the failed path to remain readable and eligible for a later scan with its exact path in the verbose log. It remains outside `local-suite` because the failure fixture is deliberately platform-specific.
+
 `test:e2e:obsidian:setup-uri-workflow` runs the repository's public Commonlib-backed CouchDB provisioning and Setup URI tools against the local CouchDB fixture. It configures a new, empty Vault in the first real Obsidian session through the visible onboarding wizard and uses Rebuild. After that device is working, it generates a new Setup URI through the registered command; the second real Obsidian Vault uses that URI for Fetch instead of reusing the initial Setup URI produced by the provisioning tool. The workflow verifies ordinary notes from the first device to the second and back again, independently enables Hidden File Sync on each device, and verifies a snippet. The retained Setup URI screenshots show only encrypted URIs and visually masked Setup URI passphrases; plaintext credentials are not captured. Files prefixed with `guide-` capture the relevant dialogue, settings panel, or workspace leaf without transient Notices. Public documentation copies selected images only after visual inspection; the E2E run does not overwrite repository documentation assets.
 
-`test:e2e:obsidian:two-vault-sync` runs a two-vault note synchronisation workflow. It verifies note creation, update, ordinary rename, a case-only file name change within the same directory, deletion, and a separate encrypted round-trip with Path Obfuscation enabled. Its target-filter scenario confirms that one Vault receives and checkpoints a remote document without reflecting it, restarts with the same profile and filter, and then reflects the stored document after the filter is broadened through the settings service. Directory case changes deliberately remain outside this scenario because they require directory-aware rename handling. The optional Markdown conflict check can be enabled with `E2E_OBSIDIAN_INCLUDE_MARKDOWN_CONFLICT=true`. It creates divergent revisions in two separate Vaults, performs a conservative merge on one Vault, edits that result again, and requires the other Vault to replace its known deleted losing revision without recreating the conflict. The separate `E2E_OBSIDIAN_INCLUDE_CONFLICT_OPERATIONS=true` check keeps four conflicts active while one Vault edits, deletes, performs a case-only rename, and performs a cross-path rename. It asserts that each operation extends the revision displayed on that device, replicates the exact resulting revision tree, and preserves the other conflict branch. During focused development, `E2E_OBSIDIAN_ONLY_CONFLICT_OPERATIONS=true` runs that self-contained scope without the ordinary, target-filter, or encrypted scenarios. Both conflict checks remain outside the default local suite.

+During focused development, `E2E_OBSIDIAN_ONLY_PARENT_CASE_DELETION=true` runs an Issue #1168 check which renames `parent/test3` to `parent/Test3` through external `node:fs/promises.rename` while Vault A is open, and verifies that the note content, Metadata, and Chunk references are not logically deleted locally, remotely, or after restart. It accepts either case spelling on Vault B, so it does not provide directory rename support or exact case convergence between devices. The natural Obsidian event sequence and resulting database state are evidence for the selected build; an existing-version reproduction result must be reported separately from fixed-version safety evidence.

 `test:e2e:obsidian:security-seed-reconnect` is a focused CouchDB release-acceptance workflow. Device A first recognises an initial remote Security Seed, stops automatic replication while remaining open, and creates an unsent note. The runner replaces only the Security Seed in the managed remote synchronisation-parameter fixture. Device A must retain its deliberately stale cached value until the next one-shot synchronisation, refresh it before sending, and upload an HKDF-encrypted payload which uses the replacement value. A fresh device B must decrypt that note and send an encrypted note back; the original device A then receives the return journey with its Vault and isolated profile preserved. Desktop Obsidian may enforce a single application instance, so the two device sessions run sequentially after the same-process stale-cache assertion has completed.
