-## 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 token issuance, rotation, revoke, approval, deny, and prompt outcomes.
-- Record authorization failures and expirations without logging secret material.
-- Provide a bounded event history visible in the UI and/or gRPC admin surface.
-
-Exit criteria:
-- Security-relevant API token events are captured without secret leakage.
-- Approval outcomes and policy changes are auditable.
-- Tests cover audit generation for the main token lifecycle and approval actions.
-- `go test ./...` passes.

+# 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
