+# Local-First Remote Sync Plan
+
+## Goal
+
+Redesign remote-backed vault handling so every platform uses the same local-first model:
+
+- every vault is a local KDBX file first
+- remote sync is an optional binding on top of that local file
+- shared remote configuration lives in the vault
+- user-specific remote credentials live in the vault
+- app-local state stores only non-secret binding metadata
+
+Android adds only one platform-specific capability on top of that model:
+
+- share/import the initial local KDBX file between devices
+
+## Product Rules
+
+1. A remote-backed vault must always have a local cache KDBX file.
+2. Opening a remote-backed vault should open the local KDBX first.
+3. Shared remote configuration must be stored in the vault, not only in app state.
+4. Remote credentials must not be stored in plaintext app-local state.
+5. Remote credentials should be stored in the vault and resolved by a stable reference.
+6. The app state file should keep only the metadata needed to reopen the local vault and find the remote binding.
+7. Sync must support both manual and automatic modes.
+8. Android-specific sharing should transfer the KDBX file, not a bespoke remote-secret bundle.
+
+## Target Data Model
+
+### In-Vault Shared Remote Profile
+
+Store a reusable remote profile in the vault with fields such as:
+
+- profile ID
+- profile name
+- backend type, initially WebDAV
+- base URL
+- remote object path
+- optional notes or labels
+- default sync policy, if shared defaults are desirable
+
+### In-Vault User Credential Binding
+
+Store user-specific credentials in the vault as normal vault data, referenced by:
+
+- remote profile ID
+- credential entry UUID, or another stable internal reference
+- optional username field override if needed
+
+The credential entry should contain the actual username/password or token.
+
+### Local App State
+
+Persist only non-secret binding state such as:
+
+- local vault path
+- selected remote profile ID
+- selected credential entry reference
+- sync policy override
+- last sync metadata
+- conflict or recovery markers
+
+## Core Flows
+
+### Create Or Configure Remote Sync
+
+1. Open or create a local vault.
+2. Create or edit a shared remote profile in that vault.
+3. Create or select a credential entry in that vault.
+4. Bind the local vault to the selected remote profile and credential reference.
+5. Choose manual or automatic sync behavior.
+
+### Reopen Existing Remote-Backed Vault
+
+1. Open the local vault file from app state.
+2. Resolve the selected remote profile from vault contents.
+3. Resolve the credential entry from vault contents.
+4. Offer or perform sync based on the binding policy.
+
+### Bootstrap A New Android Device
+
+1. Share the local KDBX file through Android Sharesheet.
+2. Import and open that KDBX locally on the new device.
+3. Select a remote profile stored in the vault.
+4. Select or create that user’s credential entry in the vault.
+5. Bind the local vault as the cache for the remote-backed setup.
+
+## Migration Requirements
+
+1. Migrate existing remote connections that save credentials in app state.
+2. On first open after upgrade, move any recoverable remote credentials into the vault.
+3. Replace saved plaintext credential state with a vault credential reference.
+4. If migration cannot write into the vault yet, hold the old state only long enough to prompt the user to complete migration.
+5. Remove legacy local plaintext credential persistence after migration is complete.
+
+## Implementation Phases
+
+### Phase 1: Domain Model
+
+- define remote profile structures independent of Gio UI
+- define credential reference structures independent of Gio UI
+- define sync binding state independent of Gio UI
+- add behavior tests for local-first remote-backed vaults
+
+### Phase 2: Vault Storage
+
+- persist remote profiles in the vault
+- persist credential references in the vault
+- resolve credentials from normal vault entries
+- add behavior tests for read/write and lookup semantics
+
+### Phase 3: State And Open Flow
+
+- shrink app state to non-secret metadata only
+- update open flows to always prefer the local cache vault
+- update reopen behavior on all platforms to use the same model
+- add migration coverage for old remote state
+
+### Phase 4: Sync Binding
+
+- bind a local vault to a selected remote profile
+- support manual sync
+- support automatic sync on open/save
+- define conflict and remote-failure handling for the local cache model
+
+### Phase 5: Android Bootstrap
+
+- add Android Sharesheet export of the current local KDBX
+- add Android import flow for a shared KDBX
+- keep the remote pivot flow consistent with desktop after local open
+
+## Open Questions
+
+1. Where in the vault should remote profiles live: custom metadata, dedicated entries, or another KDBX-compatible structure?
+2. Should credential references point to entry UUIDs directly, or should KeePassGO maintain an additional logical identifier?
+3. Should automatic sync run only on open/save initially, or also on app resume?
+4. How should multiple remote profiles per vault be presented in the UI?
+5. What should happen when the credential entry reference no longer resolves?
+
+## Recommended First Slice
+
+Implement the shared domain model and tests first:
+
+- model a local vault plus optional remote binding
+- define in-vault remote profile and credential reference semantics
+- add tests proving app state no longer needs plaintext remote credentials
+
+That slice standardizes the architecture before any Android-specific sharing work begins.
