+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`.

-## API Token And gRPC Authorization Parallel Segments
-
-These segments define the work for programmatic access control over gRPC.
-They are designed to be independently landable wherever file overlap permits.
-The feature is not complete until all segment exit criteria and the global exit criteria are satisfied.
-
-### API Segment A: Token Domain Model
-
-Scope:
-- Represent API tokens as first-class vault-backed records.
-- Mark token entries explicitly as API credentials rather than generic passwords.
-- Store token metadata:
-  token id,
-  hashed secret or verifier,
-  display name,
-  client name,
-  created at,
-  expires at,
-  disabled state.
-- Keep the persisted representation compatible with KDBX entry fields.
-
-Exit criteria:
-- A domain type exists for API tokens and round-trips through the persisted vault model.
-- Generic entry listing can distinguish API token entries from ordinary secrets.
-- Tests cover create, load, save, and parse behavior for API token entries.
-- `go test ./...` passes.
-
-### API Segment B: Token Issuance And Rotation
-
-Scope:
-- Generate new API tokens for external tools.
-- Return the cleartext token only at creation or explicit rotation time.
-- Rotate an existing token while preserving its identity and policy linkage.
-- Revoke or disable a token without deleting policy history.
-
-Exit criteria:
-- Token issuance, rotation, disable, and revoke operations exist in the domain/service layer.
-- Cleartext token material is only exposed on creation or rotation paths.
-- Tests cover generation, rotation, and disable/revoke semantics.
-- `go test ./...` passes.
-
-### API Segment C: Token Expiration
-
-Scope:
-- Allow tokens to have optional expiration timestamps.
-- Treat expired tokens as unauthenticated.
-- Surface expiration in UI and gRPC management views.
-- Support non-expiring tokens explicitly.
-
-Exit criteria:
-- Expired tokens are rejected by the gRPC authentication path.
-- Token expiration can be created, edited, and removed through the service layer.
-- Tests cover valid, expired, and non-expiring token behavior.
-- `go test ./...` passes.
-
-### API Segment D: Authorization Policy Model
-
-Scope:
-- Define an authorization model for token-scoped access.
-- Support allow and deny rules over:
-  folders/groups,
-  specific entries,
-  entry fields where needed,
-  and operation types.
-- Keep specific deny rules higher priority than broad allow rules.
-- Model “not yet decided” separately from “denied”.
-
-Exit criteria:
-- A policy evaluator exists for token, resource, and operation tuples.
-- Explicit deny overrides allow.
-- Unspecified access is distinguishable from denied access.
-- Tests cover allow, deny, inherited group scope, and exact-entry scope behavior.
-- `go test ./...` passes.
-
-### API Segment E: gRPC Authentication And Authorization Enforcement
-
-Scope:
-- Replace the current single static bearer-token interceptor with token-backed auth.
-- Authenticate callers using issued KeePassGO API tokens.
-- Authorize every gRPC method against token policy.
-- Apply scope checks to lifecycle, list, read, mutation, copy, and password-generation RPCs.
-
-Exit criteria:
-- gRPC requests authenticate through stored API tokens rather than one static shared secret.
-- Every RPC enforces token-specific authorization before mutating or revealing vault data.
-- Unauthorized requests return the correct authz/authn gRPC status.
-- Integration tests cover permitted, denied, expired, and revoked token behavior.
-- `go test ./...` passes.
-
-### API Segment F: Approval Queue And Pending Access Requests
-
-Scope:
-- When a token requests access to a resource that is neither explicitly allowed nor denied:
-  create a pending approval request.
-- Include:
-  token identity,
-  client name,
-  requested operation,
-  requested group/entry scope,
-  requested time,
-  and permanence choice.
-- Allow the request to be accepted, denied, or canceled by the user.
-
-Exit criteria:
-- Unspecified access creates a pending approval instead of silently denying or allowing.
-- Pending approvals are queryable from the application layer.
-- Canceling the prompt results in the API request failing without granting access.
-- Tests cover pending creation, approval, denial, and cancellation.
-- `go test ./...` passes.
-
-### API Segment G: Approval UI
-
-Scope:
-- Show a user-facing approval screen/dialog when a pending API request needs a decision.
-- Provide actions:
-  allow once,
-  deny once,
-  allow permanently,
-  deny permanently,
-  cancel.
-- Make the requested scope and operation clear to the user.
-- Ensure the dialog appears only for requests not already decided.
-
-Exit criteria:
-- A pending request triggers a visible approval surface in the app.
-- The user can allow, deny, or cancel from the UI.
-- Permanent decisions become persisted policy rules.
-- UI tests cover each approval outcome.
-- `go test ./...` passes.
-
-### API Segment H: gRPC Request Blocking And Resume Behavior
-
-Scope:
-- Define how an in-flight gRPC call waits for or fails on user approval.
-- Hold the request while approval is pending within a bounded timeout.
-- Return unauthenticated or permission-denied when denied/canceled/expired.
-- Resume the original call automatically when approval is granted.
-
-Exit criteria:
-- Pending requests block safely without leaking goroutines.
-- Allowed requests resume and complete without the client reissuing the call where practical.
-- Denied and canceled requests return a consistent gRPC status code and message.
-- Tests cover timeout, allow, deny, and cancel paths.
-- `go test ./...` passes.
-
-### API Segment I: Token Management UI
-
-Scope:
-- Add UI for listing API tokens.
-- Create token flow with one-time secret display.
-- Edit token display metadata and expiration.
-- Disable, revoke, and rotate tokens.
-- Show effective policy summary per token.
-
-Exit criteria:
-- Users can manage API tokens from the app UI end to end.
-- One-time token display is explicit and not re-shown later.
-- Expiration and disable state are visible.
-- UI tests cover create, rotate, disable, revoke, and edit flows.
-- `go test ./...` passes.
-
-### API Segment J: Policy Management UI
-
-Scope:
-- Let users define folder, entry, and operation scopes for each token.
-- Show explicit allow and deny rules.
-- Show inherited implications of a folder-level rule.
-- Let users review prior permanent decisions created from approval prompts.
-
-Exit criteria:
-- Users can inspect and edit token policy from the UI.
-- Folder-level and entry-level rules are distinguishable and editable.
-- Permanent prompt decisions are visible as policy.
-- UI tests cover rule creation, update, and deletion.
-- `go test ./...` passes.

-### API Segment K: Audit And Event History
-
-Scope:

-- Record authorization failures and expirations without logging secret material.
-- Provide a bounded event history visible in the UI and/or gRPC admin surface.

-- KDBX security settings are product-configurable at the major cipher/KDF family level for both new vault creation and existing sessions.
-- The current accessibility support boundary is documented in `docs/accessibility.md`, while in-repo focus and labeling behavior remains tested.

+# KeePassGO Browser Extension
+
+Shared extension assets for Firefox and Chromium-based browsers live here.
+
+The Arch package installs this directory under `/usr/share/keepassgo/browser-extension/`. On Linux desktop builds, launching KeePassGO refreshes the user-scoped native messaging manifests for Firefox and for any installed Chrome or Chromium `KeePassGO Browser` extension ids it can discover from browser profiles.
+
+- `manifest.firefox.json` uses the fixed Firefox extension id `browser@keepassgo.com`
+- `manifest.chromium.json` is the Chromium/Chrome manifest template
+- `background.js` caches per-tab match state, updates the toolbar badge, keeps token-scoped approval state visible, and talks to the native messaging host `com.keepassgo.browser`
+- `content.js` fills username and password fields on the current page, keeps fills tied to the focused form when possible, and shows inline KeePassGO field affordances when matches exist
+- `options.html` stores the API token in browser extension storage
+
+The extension sends the API token to the native host on each request. The bridge does not store the token on disk.
+
+Quick extension-side checks:
+
+```bash
+node --test browser/extension/background.test.cjs browser/extension/content.test.cjs
+```
+
+Reproducible Chromium validation:
+
+```bash
+make browser-extension-validate
+```
+
+That command validates Firefox by default. Use `make browser-extension-validate BROWSER=chromium` for the Chromium harness.

+# Browser Extension
+
+KeePassGO browser integration uses:
+
+- the existing local gRPC API in KeePassGO
+- API tokens for authorization
+- a tiny native messaging host for browser-to-gRPC transport adaptation
+
+The browser extension does **not** talk to vault files directly.
+
+## Security Model
+
+- KeePassGO remains the source of truth for authentication, authorization, approvals, and audit events.
+- The browser extension stores the API token in browser extension storage.
+- The native messaging host receives the token on each request from the extension.
+- The native messaging host uses the token only to attach `authorization: Bearer ...` metadata to the local gRPC request.
+- The native messaging host does not persist the token to disk.
+
+The native messaging host is therefore part of the trusted client for that browser profile. Scope the API token accordingly.
+
+## RPCs Used
+
+The browser integration uses:
+
+- `GetSessionStatus`
+- `FindBrowserLogins`
+- `GetBrowserCredential`
+
+The browser feature intentionally stays on the same secure gRPC surface used by other trusted automation.
+
+## Default Listener
+
+On desktop KeePassGO listens on a Unix socket by default:
+
+- primary location: under the user runtime directory
+- fallback: `/run/user/<uid>` if present
+- final fallback: a private directory under the system temp directory
+
+Override the listener with `-grpc-addr` or `KEEPASSGO_GRPC_ADDR`, for example:
+
+```bash
+KEEPASSGO_GRPC_ADDR=tcp://127.0.0.1:47777 ./keepassgo
+```
+
+## Native Host
+
+Build the bridge:
+
+```bash
+go build ./cmd/keepassgo-browser-bridge
+```
+
+On Linux desktop builds, KeePassGO now refreshes the user-scoped native messaging manifests on launch. That automatic update always installs the Firefox manifest and also installs Chrome or Chromium manifests when it finds an installed `KeePassGO Browser` extension in that browser profile. The Arch package also ships the extension assets under `/usr/share/keepassgo/browser-extension/`.
+
+Install a Firefox native messaging manifest:
+
+```bash
+./keepassgo-browser-bridge install-native-host --browser firefox --binary /absolute/path/to/keepassgo-browser-bridge
+```
+
+Install a Chromium native messaging manifest:
+
+```bash
+./keepassgo-browser-bridge install-native-host --browser chromium --binary /absolute/path/to/keepassgo-browser-bridge --extension-key-file /path/to/chromium-extension-public-key.txt
+```
+
+Chrome and Chromium require the actual extension id in the native host manifest. KeePassGO can derive that id from the Chromium manifest public key so you do not have to type it separately.
+
+For a fixed Chromium ID:
+
+1. Keep a stable Chromium extension signing key outside the repo.
+2. Add the corresponding public key to the Chromium manifest as `"key": "<base64-public-key>"`.
+3. Use the same public key with `install-native-host --extension-key-file ...` so the native host manifest is locked to that stable extension ID.
+
+## Extension Setup
+
+Firefox:
+
+1. Load `browser/extension/manifest.firefox.json` as a temporary add-on or package it as an extension.
+2. Open the extension settings page.
+3. Paste an API token scoped for browser login lookup and credential copy.
+
+Chromium / Chrome:
+
+1. Load a Chromium manifest based on `browser/extension/manifest.chromium.json`, or install the published extension when that distribution exists.
+2. Start KeePassGO once so it can refresh the native host manifest for the discovered extension id.
+3. Configure the API token in the extension settings page.
+
+## Current Browser Flow
+
+- The extension checks sign-in pages in the background and caches per-tab match state instead of waiting for the popup to be opened first.
+- The toolbar badge shows when KeePassGO found matches for the current page.
+- Username and password fields get an inline KeePassGO affordance that opens a candidate chooser anchored to the focused field and keeps fills scoped to that field's form when possible.
+- If a fill request needs user approval, the extension keeps the pending state visible in both the page affordance and the popup until KeePassGO resolves it, using the token-scoped pending-approval count from the local gRPC API.
+
+For extension-side regression checks, run:
+
+```bash
+node --test browser/extension/background.test.cjs browser/extension/content.test.cjs
+```
+
+For a reproducible real-browser Chromium validation harness, run:
+
+```bash
+make browser-extension-validate
+```
+
+That target:
+
+- validates the Firefox flow by default with a temporary addon install
+- can also validate Chromium with `make browser-extension-validate BROWSER=chromium`
+- builds the native messaging bridge
+- starts a stub KeePassGO gRPC server and a local login page
+- drives the browser through inline match discovery, approval visibility, and fill completion
+
+If validation fails, the script preserves its temporary workspace path so the captured HTML, screenshots, logs, and native-host files can be inspected.
+
+## Required Token Scope
+
+At minimum, the browser token should have policy rules allowing:
+
+- `list_entries` for the groups you want the browser to search
+- `copy_username` for entries the browser may fill
+- `copy_password` for entries the browser may fill
+- `copy_url` for entries the browser may confirm against page URL

+# 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.
