+description: Build and run the KeePassGO Android APK for emulator testing. Use when work requires `make apk`, APK install/launch, emulator validation, or checking known KeePassGO Android regressions such as black screens, clipboard, open flow, or local sync behavior.
+---
+
+# KeePassGO APK Test
+
+Use this skill together with the installed `android-emulator-debug` skill. That skill covers generic emulator and `adb` mechanics. This skill adds the KeePassGO-specific build, install, and validation requirements that have already been established in this repo.
+
+## Use This Skill When
+
+- Building `build/keepassgo.apk`.
+- Installing or launching KeePassGO in the Android emulator.
+- Verifying Android regressions such as black screen, clipboard, open flow, file picker, or Advanced Sync behavior.
+- Checking whether a Gio or Android toolchain change broke runtime behavior.
+
+## Known Working Environment
+
+- Preferred emulator AVD: `KeepassGoAPI35`
+- Package: `org.julianfamily.keepassgo`
+- Activity: `org.gioui.GioActivity`
+- Local APK build defaults:
+  `ANDROID_SDK_ROOT=/opt/android-sdk`
+  `ANDROID_NDK_ROOT=/opt/android-ndk`
+  `JAVA_HOME=/usr/lib/jvm/java-25-openjdk`
+- CI APK build uses:
+  `ANDROID_SDK_ROOT=/opt/android-sdk`
+  `ANDROID_NDK_ROOT=/opt/android-sdk/ndk`
+  `JAVA_HOME=/usr/lib/jvm/java-21-openjdk-amd64`
+
+## Known Regression
+
+- `gioui.org v0.9.0` caused a black screen in the `KeepassGoAPI35` emulator.
+- `gioui.org v0.8.0` rendered correctly in the same environment.
+- If Android rendering regresses after a Gio change, treat Gio as a primary suspect and verify against this known-bad versus known-good history before guessing about app logic.
+
+## Safety Rules
+
+- Do not clobber the user’s real KeePassGO state while testing.
+- For host-side validation, use isolated state such as:
+  `KEEPASSGO_STATE_DIR="$(mktemp -d)" go test ./...`
+- Prefer sanitized demo or test vaults when seeding emulator tests.
+- If a real vault is absolutely required to reproduce a problem, do not modify it and do not overwrite the user’s existing recent-vault state.
+
+## Build Workflow
+
+1. Verify the JDK/SDK paths match the known working environment.
+2. Build with `make apk`.
+3. If `make apk` fails, inspect the effective `JAVA_HOME`, `ANDROID_SDK_ROOT`, and `ANDROID_NDK_ROOT` before changing code.
+4. If the problem is Android-only, avoid desktop-only conclusions from `go test ./...`.
+
+Typical local build:
+
+```sh
+JAVA_HOME=/usr/lib/jvm/java-25-openjdk make apk
+```
+
+## Emulator Workflow
+
+1. Reuse an existing emulator session if one is already running.
+2. Prefer the `KeepassGoAPI35` AVD.
+3. Install with `adb install -r build/keepassgo.apk`.
+4. Launch with:
+
+```sh
+adb shell monkey -p org.julianfamily.keepassgo -c android.intent.category.LAUNCHER 1
+```
+
+5. Confirm focus before drawing conclusions:
+
+```sh
+adb shell dumpsys window | rg 'mCurrentFocus|mFocusedApp'
+```
+
+6. Capture evidence before editing code:
+  screenshot
+  focused window
+  relevant `logcat`
+
+## Validation Checklist
+
+- APK builds successfully with `make apk`.
+- App launches to `org.julianfamily.keepassgo/org.gioui.GioActivity`.
+- Screenshot shows the expected screen, not just a black frame.
+- `logcat` shows no app crash or Android runtime fatal error.
+- If the change is about user interaction, perform the tap-through in the emulator instead of stopping at install success.
+
+## Issue-Specific Checks
+
+### Black Screen
+
+- Confirm the app is focused.
+- Capture a screenshot and `logcat` before changing anything.
+- Compare the current Gio version against the known `v0.9.0` regression history.
+- If needed, test whether a minimal Gio example renders in the same emulator before blaming KeePassGO layout code.
+
+### Clipboard
+
+- Verify behavior in the emulator, not just unit tests.
+- Android clipboard writes must use the Gio-native command path, not desktop clipboard backends.
+
+### File Picker Or Local Sync
+
+- Verify the picker flow on Android itself.
+- Prefer document-stream or content-URI based behavior over raw filesystem paths when Android permissions are involved.
+
+## Report Back
+
+When closing out work, state:
+
+- the exact build command used
+- whether the emulator session was reused or newly started
+- whether install succeeded
+- whether the app actually rendered
+- what was verified manually in the emulator
+- what remains unverified

+description: KeePassGO-specific ship workflow. Use when the user says `ship it` in this repository and expects the current work to be committed, the Arch package rebuilt and installed, the Android APK rebuilt and zipped, the ZIP uploaded to Nextcloud, and the rebuilt app launched in the emulator with a controlled demo vault opened.
+---
+
+# KeePassGO Ship It
+
+Use this skill only in the KeePassGO repository. This is not a global shorthand.
+
+Use it together with:
+- `android-emulator-debug` for emulator and `adb` mechanics
+- `keepass-credentials` for Nextcloud credentials
+- `public-repo-sanitization` before the commit/push step
+
+## Meaning Of `ship it`
+
+When the user says `ship it`, do all of this unless they narrow the scope:
+
+1. Commit the relevant KeePassGO source changes first.
+2. Build and install the Arch package from that committed source.
+3. Build the Android APK from that same committed source.
+4. Zip the APK.
+5. Upload the ZIP to the user's configured Nextcloud DAV destination for this repository.
+6. Install the rebuilt APK in the emulator.
+7. Launch the rebuilt app in the emulator.
+8. Open a controlled demo vault in the emulator.
+
+Do not stop after the commit or after the package build. `ship it` means finish the full loop.
+
+## Required Sequence
+
+### 1. Commit First
+
+- Make sure the worktree state intended for shipping is committed before building.
+- If the repo is dirty in unrelated ways, commit only the relevant changes.
+- Before the commit or push, run the public-repo sanitization checks.
+
+### 2. Build And Install The Arch Package
+
+From the repo root:
+
+```sh
+make archlinux-pkgbuild
+cd packaging/archlinux/keepassgo-git
+makepkg -si --noconfirm
+```
+
+The installed package version must correspond to the committed source, not a dirty worktree.
+
+### 3. Build The APK
+
+Use the repo's known-good local JDK unless the environment already proves otherwise:
+
+```sh
+JAVA_HOME=/usr/lib/jvm/java-25-openjdk make apk
+```
+
+If that JDK is unavailable on the current host, use the working replacement already established for the machine and say so in the closeout.
+
+### 4. Zip The APK
+
+- Create the ZIP under the globally required temporary secret-safe directory.
+- Use a name that includes the commit, for example:
+  `keepassgo-<shortsha>-apk.zip`
+
+### 5. Upload To Nextcloud
+
+- Get credentials and the DAV endpoint with `keepass-http`, not by asking the user if KeePass likely has them.
+- Prefer the established KeePass entry and DAV destination already in use for this repository's shipping workflow.
+- Use the globally required temporary secret-safe directory for any temporary curl config or secret material.
+- Ensure that directory exists with mode `700`.
+- Create secret temp files with mode `600`.
+- After upload, zero and unlink the temp secret file. Do not use `rm -f` or `rm -rf`.
+
+### 6. Emulator Install And Launch
+
+- Reuse the existing emulator session if one is already running.
+- Install with replacement:
+
+```sh
+adb install -r build/keepassgo.apk
+```
+
+- Launch KeePassGO and confirm it is focused.
+- Treat the emulator as timing-sensitive. If Android shows a transient "Wait" style ANR dialog and the user says the app is otherwise fine, do not misclassify that as an app-logic failure.
+
+### 7. Open A Controlled Demo Vault
+
+- Do not rely on the user's real vault for this step.
+- Use a controlled/sanitized demo vault that you can unlock yourself.
+- Open it in the emulator before closing out `ship it`.
+- Capture a screenshot if needed to verify the app really rendered and opened the vault.
+
+## Closeout Requirements
+
+When reporting back after `ship it`, include:
+- the commit that was shipped
+- the installed Arch package version
+- the APK path
+- the uploaded ZIP URL
+- confirmation that the emulator app was launched
+- confirmation that the controlled demo vault was opened
+
+## Constraints
+
+- Keep this workflow specific to KeePassGO.
+- Preserve emulator state; do not kill or reset it unless the user explicitly asks.
+- Do not use `rm -rf`.
+- Do not use `rm -f`.

 - Track `gogio` as a Go tool and keep a reproducible `make apk` path for Android packaging.
+- Keep the Android build requirements aligned with the known working setup:

+- Remember the known Android runtime regression:
+  `gioui.org v0.9.0` produced a black screen on the `KeepassGoAPI35` emulator, while `gioui.org v0.8.0` rendered correctly. Treat Gio upgrades on Android as regression-sensitive and verify them on-device or in the emulator.
+- When validating an APK in the emulator, prefer the known KeePassGO setup:
+  AVD `KeepassGoAPI35`,
+  package `org.julianfamily.keepassgo`,
+  activity `org.gioui.GioActivity`.
+- Do not run emulator/manual APK tests against the user’s real persisted app state.
+  Use an isolated `KEEPASSGO_STATE_DIR` for host-side validation, and when emulator testing requires seeded vault data, use sanitized test/demo vaults rather than the user’s real vault files whenever possible.
 - When running tests or other automated validation that may touch persisted UI state, set `KEEPASSGO_STATE_DIR` to an isolated temporary directory so recent-vault history and other local state do not pollute the user’s real config.
 - Prefer commands shaped like `KEEPASSGO_STATE_DIR=\"$(mktemp -d)\" go test ./...` for ad hoc local validation unless a test already manages its own isolated state directory.

+## UI Review Follow-Ups
+
+These items came from a hands-on emulator and desktop walkthrough.
+They should be treated as usability work, not just polish.
+
+### Cross-Platform Workflow Parity
+
+These items are required to keep desktop, Android phone, and Android tablet
+feeling like the same application rather than three related UIs.
+
+- Workflow parity:
+  define canonical workflows for open, unlock, set up remote sync, use remote
+  sync, browse entries, and edit entries.
+- Workflow parity:
+  ensure desktop, phone, and tablet use the same action names and the same
+  primary next steps for those workflows.
+- Workflow parity:
+  remove or reduce platform-specific workflow exceptions where the same user
+  intent currently takes a different route on different form factors.
+- Testing:
+  add cross-mode behavior tests that assert workflow order and action
+  prominence, not just label presence.
+- Testing:
+  add explicit lifecycle/open-screen tests for reachability of the primary
+  action on desktop, phone, and tablet layouts.
+- Testing:
+  add explicit remote-sync workflow tests that prove setup, settings, use, and
+  removal are reachable from the same primary affordance family across modes.
+- Android verification:
+  validate changed lifecycle/open/sync workflows on the emulator or a device,
+  including with the on-screen keyboard visible.
+- Android verification:
+  treat “present but below the fold or behind an unexpected branch” as a parity
+  failure, not as acceptable platform variation.
+
+### Primary Workflow Changes
+
+These should remain in the main user flow rather than being hidden behind a settings gear.
+
+- Local open flow:
+  make the start screen primarily about opening a vault, not configuring one.
+- Local open flow:
+  keep recent vault selection visually obvious and clearly tappable.
+- Local open flow:
+  once a recent vault is preselected, collapse the full path into a compact summary with a `Change...` affordance.
+- Local open flow:
+  improve Android field focus and IME behavior so the master-password field reliably takes focus and summons the keyboard.
+- Local open flow:
+  show an explicit progress state and allow cancel or retry while opening a vault, especially on Android.
+- Remote open flow:
+  break the remote form into clearer sections such as `Location` and `Authentication`.
+- Remote open flow:
+  make recent remote connections easier to scan with a friendlier label than raw URL and path.
+- Locked screen:
+  show clear vault identity and target summary so the user knows what is being unlocked.
+- Entries screen:
+  tighten the top strip on phone so tabs, breadcrumbs, and group controls do not fight for the same row.
+- Entries screen:
+  make breadcrumbs compress more aggressively on phone.
+- Entries screen:
+  improve entry-row hierarchy and selected-state contrast.
+- Entries screen:
+  provide section-specific empty states for search, recycle bin, API tokens, and empty groups.
+- Group navigation:
+  make the distinction between root, current group, and child groups more obvious.
+- Group navigation:
+  separate navigation controls from group-management controls more clearly.
+- Entry detail:
+  tighten field spacing and reduce unnecessary whitespace.
+- Entry detail:
+  group password reveal and copy actions more clearly.
+- Entry detail:
+  make attachments more visible and actionable.
+- Entry edit:
+  break the editor into clearer subsections such as `Basics`, `Notes`, `Custom Fields`, `History`, and `Attachments`.
+- Entry edit:
+  make add/remove affordances for custom fields more visually obvious.
+- Entry edit:
+  make generated-password draft state more explicit before save.
+- Recycle bin:
+  make it visually distinct from normal entry browsing.
+- API tokens:
+  give token list, token detail, and policy editing a clearer dedicated management surface.
+- API tokens:
+  make policy rows easier to scan by separating effect, operation, and resource visually.
+- API audit:
+  improve empty-state guidance and provide quick filtering by token, decision, and operation.
+- Synchronize:
+  keep the split-button pattern, but reduce the visual weight of the sync controls and make advanced sync affordances clearer.
+- Synchronize:
+  avoid layout-shifting success banners and keep noncritical notifications ephemeral.
+- Phone layout:
+  continue reducing header and control density so content appears sooner.
+- Mobile reliability:
+  fix Android local-open ANR behavior before deeper mobile polish.
+- Autofill UX:
+  surface whether a fill candidate was found, ambiguous, blocked, or awaiting approval.
+
+### Settings Gear Candidates
+
+These are important, but they should likely move behind a dedicated settings gear or advanced/settings surface instead of occupying first-run or day-to-day credential screens.
+
+- Vault security:
+  move `Cipher` and `KDF` off the main local-open screen and into `Advanced` or `Vault Settings`.
+- Vault security:
+  frame security settings as vault configuration rather than freeform text fields in the primary workflow.
+- Remote preferences:
+  move remembered-auth behavior details and retention policy explanations into settings/help rather than the main open flow.
+- UI preferences:
+  save and expose view preferences such as group-tools collapse state and any future dense/comfortable layout toggle under settings.
+- Autofill behavior:
+  app and browser allowlists, package rules, and first-fill approval preferences should live under a settings/privacy area.
+- Sync defaults:
+  source/direction defaults, conflict preferences, and any future background sync behavior should live under settings.
+- Notification preferences:
+  banner timeout, ephemeral notices, and other noncritical UI feedback tuning should live under settings.
+- Accessibility preferences:
+  future display-density, contrast, reduced-motion, or keyboard-focus tuning should live under settings.
+
+### Exit Criteria
+
+- The main workflow screens prioritize opening, browsing, copying, editing, and synchronizing credentials.
+- Advanced vault/security and behavior preferences are no longer cluttering the primary open and browsing flows.
+- Phone and desktop layouts both present a clear information hierarchy.
+- The Android open flow is reliable enough to review and use without ANR during ordinary vault-open operations.

+### Segment 21: Accessibility Fill Generalization
+
+Scope:
+- Extend Android accessibility-based fill beyond the current Chrome demo path.
+- Support package-specific rules so apps with stable package identities can have tailored matching behavior.
+- Support view-id matching so custom login forms can be identified more reliably than by generic hints alone.
+- Support app allowlists so only approved apps/packages are eligible for accessibility-based credential fill.
+- Require an approval step before filling into a newly seen app/package unless the user has already made a persistent decision.

+Exit criteria:
+- The design for package-specific rules, view-id matching, app allowlists, and first-fill approval is implemented or broken into executable sub-slices.
+- Accessibility fill no longer depends solely on Chrome-style generic username/password heuristics.
+- New app/package fill attempts can be allowed, denied, or made persistent by the user.

+# 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.
