-### Agent tools
+### Local file browsing
 
-The browser embeds a WebSocket server (using libsoup) that allows external
-AI agents to control the browser programmatically. Connect to
-`ws://localhost:17777/agent` and send JSON tool commands.
+sovereign_browser is designed to run websites directly from local files —
+open an `index.html` from its directory and navigate as if it were served
+over HTTP. No web server required. This is a deliberate design choice:
+security is moved up to the Qube level, so the browser doesn't need the
+traditional security restrictions (same-origin policy, CORS) that would
+block local-file web apps.
 
-The server starts before the login dialog and remains available throughout
-the browser's lifecycle. The browser starts normally with the GTK login
-dialog — no blocking wait. An agent can log in at any time: while the dialog
-is showing, or after the browser is already running. If an agent logs in
-while the dialog is open, the agent's login takes priority.
+**What works on `file://` pages:**
 
-**Login tools** (available before login):
+- **Relative links** between pages — `index.html` → `about.html`,
+  `subdir/page.html`, `../index.html`, `../../../deep/page.html`
+- **Cross-origin access** — all `file://` URLs are treated as same-origin.
+  Iframes can access their parent's DOM, `window.open()` popups are
+  accessible, and `fetch()`/XHR work across directories.
+- **`fetch()` and `XMLHttpRequest`** — load local JSON, text, and other
+  files via relative paths (returns `status=0`, the `file://` convention)
+- **External resources** — CSS stylesheets, JavaScript files, SVG images,
+  favicons, `<picture>`/`srcset`, `<object>`/`<embed>`
+- **Video and audio playback** — MP4 video and M4A audio play correctly
+  with full duration/dimension metadata
+- **All browser storage** — `localStorage`, `sessionStorage`, `cookies`,
+  and `IndexedDB` all work fully (open, upgrade, put, get, count)
+- **`history.pushState`/`replaceState`** — SPA-style routing works on
+  `file://` URLs
+- **Query strings and hash fragments** — preserved in `location.href`,
+  accessible via `location.search`/`location.hash`
+- **URL-encoded filenames** — `encoded%20name.html` (file on disk:
+  `encoded name.html`) loads correctly
+- **Form submissions** — GET forms append query strings to the target
+  page; POST forms navigate (body silently dropped, no server)
+- **`window.open()`** — opens local pages in new tabs
 
-- `login_status` — check if logged in
-- `login` — authenticate with method: `local` (nsec), `seed` (BIP-39
-  mnemonic), `readonly` (npub), `nip46` (bunker:// URL), or `nsigner`
-  (hardware signer via serial/unix/tcp/qrexec transport)
-- `logout` — clear signer and reset state
-- `switch_identity` — change identity (same params as login)
+**Known limitations (WebKit engine quirks, not bugs):**
 
-**Browser tools** (available after login):
+- `fetch()` for missing files throws `Load failed` instead of returning an
+  error Response (no HTTP status codes on `file://`)
+- `<video>`/`<audio>` `error` events don't fire for missing source files
+  (valid media works perfectly)
+- Cache API (CacheStorage) rejects non-HTTP/HTTPS URLs — use IndexedDB
+  instead for local-file storage
 
-- Navigation: `open`, `back`, `forward`, `reload`, `get_url`, `get_title`
-- Inspection: `snapshot` (accessibility tree with element refs), `get_text`,
-  `get_html`, `get_attr`, `eval` (run JavaScript)
-- Interaction: `click`, `fill`, `type`, `press`, `scroll`, `hover`,

+# Local File Browsing Assessment — sovereign_browser
+
+**Date:** 2026-07-16
+**Test site:** [`tests/local-site/`](index.html)
+**Browser:** sovereign_browser (WebKitGTK + libsoup-3.0)
+**Goal:** Verify that sovereign_browser can load and operate a multipage
+website directly from the local filesystem (`file://`) with no web server,
+allowing cross-origin access between local files — as required by the
+"security moved to the Qube level" design.
+
+---
+
+## Summary
+
+**Local file browsing in sovereign_browser works remarkably well.** The vast
+majority of edge cases pass. WebKitGTK's `file://` handler, combined with
+sovereign_browser's permissive local-file policy, allows a full multipage
+website to be opened and operated from disk just as if it were served over
+HTTP. Only a handful of minor issues were found, and most are WebKit engine
+quirks rather than sovereign_browser bugs.
+
+**Verdict:** No blocking fixes are required for local-file browsing to work.
+The issues below are polish/UX improvements.
+
+---
+
+## Test Matrix
+
+| # | Edge case | Page | Result | Notes |
+|---|-----------|------|--------|-------|
+| 1 | Relative links between sibling pages | [`index.html`](index.html) → [`about.html`](about.html) | ✅ PASS | Links resolve to correct `file://` URLs |
+| 2 | Links into subdirectories | [`index.html`](index.html) → [`subdir/page.html`](subdir/page.html) | ✅ PASS | |
+| 3 | Links back out with `../` | [`subdir/page.html`](subdir/page.html) → [`index.html`](index.html) | ✅ PASS | |
+| 4 | Deeply nested paths (3 levels) | [`subdir/deep/deeper/deepest.html`](subdir/deep/deeper/deepest.html) | ✅ PASS | `../../../` resolves correctly |
+| 5 | External stylesheet (relative) | [`assets/site.css`](assets/site.css) | ✅ PASS | 21 CSS rules loaded on every page |
+| 6 | SVG favicon | [`assets/favicon.svg`](assets/favicon.svg) | ✅ PASS | `link[rel=icon]` href resolved |
+| 7 | SVG image via `<img>` | [`assets/logo.svg`](assets/logo.svg) | ✅ PASS | `naturalWidth` correct, `complete=true` |
+| 8 | `<picture>` + `<source srcset>` | [`gallery.html`](gallery.html) | ✅ PASS | `currentSrc` selected correctly |
+| 9 | `<img srcset>` with `1x/2x` | [`gallery.html`](gallery.html) | ✅ PASS | |
+| 10 | Lazy-loaded image (`loading="lazy"`) | [`gallery.html`](gallery.html) | ✅ PASS | |
+| 11 | External `<script src>` (sibling) | [`assets/home.js`](assets/home.js) | ✅ PASS | Script ran, updated DOM |
+| 12 | External `<script src>` (`../`) | [`assets/external.js`](assets/external.js) | ✅ PASS | Loaded from parent dir |
+| 13 | `fetch()` a local JSON file | [`data.html`](data.html) → [`assets/data.json`](assets/data.json) | ✅ PASS | `status=0` (file:// convention), body returned |
+| 14 | `XMLHttpRequest` a local file | [`data.html`](data.html) | ✅ PASS | `status=0`, responseText populated |

+| 17 | `fetch()` a missing file | [`data.html`](data.html) → `assets/does-not-exist.json` | ⚠️ MINOR | `fetch()` throws "Load failed" instead of returning a 404 response. This is standard WebKit `file://` behavior — there is no HTTP status for local files. **Not a bug.** |
+| 18 | `<iframe>` loading a sibling page | [`iframe.html`](iframe.html) → [`about.html`](about.html) | ✅ PASS | `load` event fired, `readyState=complete` |
+| 19 | `<iframe>` loading a subdirectory page | [`iframe.html`](iframe.html) → [`subdir/page.html`](subdir/page.html) | ✅ PASS | |
+| 20 | Cross-iframe DOM access (same-origin) | [`iframe.html`](iframe.html) | ✅ PASS | **Critical finding:** `contentDocument.title` readable — all `file://` URLs are treated as same-origin. This is exactly what we want for local development. |
+| 21 | `<iframe srcdoc>` | [`iframe.html`](iframe.html) | ✅ PASS | |

+| 25 | Form targeting a new window (`target="_blank"`) | [`form.html`](form.html) | ✅ PASS | Opens in new tab |
+| 26 | Form targeting an iframe (`target="form-frame"`) | [`form.html`](form.html) | ✅ PASS | |
+| 27 | `localStorage` | [`storage-test.html`](storage-test.html) | ✅ PASS | Set/get/remove all work; length tracking correct |
+| 28 | `sessionStorage` | [`storage-test.html`](storage-test.html) | ✅ PASS | Set/get/remove all work |
+| 29 | `document.cookie` | [`storage-test.html`](storage-test.html) | ✅ PASS | Set/get work; multiple cookies visible |
+| 30 | `IndexedDB` | [`storage-test.html`](storage-test.html) | ✅ PASS | Open, upgrade (create object store), put, get, count — all work |

+| 34 | `history.replaceState()` | [`history.html`](history.html) | ✅ PASS | URL updated with `?replaced=1` |
+| 35 | `history.back()` / `forward()` | browser `back`/`forward` MCP tools | ✅ PASS | Navigates correctly between file:// pages |
+| 36 | Hash fragment in URL | [`hash.html#section-2`](hash.html) | ✅ PASS | `location.hash` = `#section-2` |
+| 37 | `hashchange` event | [`hash.html`](hash.html) | ✅ PASS | (page wired correctly) |
+| 38 | URL-encoded filename (`encoded%20name.html`) | [`encoded name.html`](encoded%20name.html) | ✅ PASS | Percent-encoding decoded, correct file loaded |
+| 39 | Query string on file:// URL | [`query.html?foo=bar&baz=qux`](query.html) | ✅ PASS | File loaded, `location.search` preserved, `URLSearchParams` works |
+| 40 | Missing page (404 equivalent) | `does-not-exist.html` | ✅ FIXED | URL bar now shows failed URL (Issue #1 fixed) |

+
+---
+
+## Issues Found
+
+### Issue #1 — Missing page falls back to `about:blank` (FIXED ✅)
+
+**What was happening:** When navigating to a `file://` URL that does not
+exist, the browser displayed an error message but the URL bar showed
+`about:blank` instead of the requested URL.
+
+**Fix applied:** Updated [`on_load_failed()`](src/tab_manager.c:1335) in
+`src/tab_manager.c` to:
+1. Accept the `tab_info_t*` as `user_data` (changed signal connection from
+   `NULL` to `tab`).
+2. Set the URL bar text to `failing_uri` (skipping `about:blank`).
+3. Update `tab->current_url` to the failing URI.
+4. Set the tab title to the error message so the tab bar shows something
+   meaningful instead of "Loading…".
+
+**Verified:** After the fix, navigating to a missing file shows the failed
+`file://` URL in the address bar (confirmed via `get_url` MCP tool).
+
+---
+
+### Issue #2 — `<video>`/`<audio>` error events don't fire for missing sources (MINOR / WebKit quirk)
+
+**Note: Media playback with valid files works perfectly.** Tested with a
+real MP4 video (Big Buck Bunny, 596s, 640x360) and M4A audio (Neon Dream,
+3277s). Both reach `can play` state with correct duration and dimensions.
+This issue only affects the error path when a media file is missing.
+
+**What happens:** When a `<video>` or `<audio>` element references a local
+file that doesn't exist, the `error` event does not fire. The `loadstart`
+event fires, but then the load silently fails without an error event. The
+element stays in a "not loaded" state indefinitely.
+
+**Why it matters:** Web apps that rely on `error` events to show fallback
+content or retry logic won't work correctly for missing media files.
+
+**Likely cause:** This is a WebKitGTK engine behavior, not a
+sovereign_browser bug. The `file://` loader may not emit media element
+errors the same way the HTTP loader does.
+
+**Suggested fix:** None required — this is upstream WebKit behavior. If it
+becomes a problem, a workaround would be to check `networkState` or
+`readyState` after a timeout. Not worth fixing for the local-file use case.
+
+**Severity:** Very low. Only affects missing media files, which is an edge
+case.
+
+---
+
+### Issue #3 — `fetch()` for missing files throws instead of returning an error response (MINOR / WebKit quirk)
+
+**What happens:** `fetch('missing.json')` on a `file://` page throws a
+`TypeError: Load failed` exception rather than returning a Response with
+`ok=false` and a status code.
+
+**Why it matters:** Code using `fetch().then(r => r.ok ? ... : ...)` will
+hit the catch branch instead of the error-handling branch. This is
+different from HTTP behavior.
+
+**Likely cause:** Standard WebKit `file://` behavior — there's no HTTP
+status code to return for a missing local file, so the fetch promise
+rejects.
+
+**Suggested fix:** None required — this is upstream WebKit behavior and is
+consistent with Safari and other WebKit-based browsers. Document it as a
+known difference from HTTP.
+
+**Severity:** Very low. Developers writing local-file apps should use
+try/catch with fetch.
+
+---
+
+### Issue #4 — Page title shows `(none)` in browser log on initial load (FIXED ✅)
+
+**What was happening:** The browser log frequently showed
+`[loaded] file://... -- title: (none)` even for pages that have a `<title>`.
+The title arrived slightly after the `LOAD_FINISHED` event.
+
+**Fix applied:**
+1. Added a new [`on_title_changed()`](src/tab_manager.c:1361) handler
+   connected to the webview's `notify::title` signal. It logs the title
+   as `[title] URL -- Title` when the title actually becomes available,
+   and updates the tab title.
+2. Simplified the `[loaded]` log line in `on_load_changed()` to just log
+   the URL (no more `title: (none)` noise). The title is now logged
+   separately via the `notify::title` handler.
+
+**Verified:** After the fix, the log shows:
+```
+[title] file:///...index.html -- Local Site — Home
+[loaded] file:///...index.html
+```
+instead of the old `[loaded] ... -- title: (none)`.
+
+---
+
+### Issue #5 — Cache API (CacheStorage) rejects non-HTTP/HTTPS URLs (MINOR / WebKit restriction)
+
+**What happens:** `caches.open('my_cache')` succeeds, but
+`cache.put(request, response)` rejects with the error:
+`"Request url is not HTTP/HTTPS"` when the request URL is not an HTTP/HTTPS
+URL. This means the Cache API cannot be used to store entries keyed by
+`file://` URLs or custom schemes.
+
+**Why it matters:** Web apps that use the Cache API for offline storage
+(e.g., service workers caching responses) will not work on `file://` pages.
+The Cache API is the only standard browser storage that has this restriction
+— localStorage, sessionStorage, IndexedDB, and cookies all work fine on
+`file://`.
+
+**Likely cause:** This is a WebKit engine restriction. The Cache API
+spec requires that request URLs be HTTP or HTTPS. WebKit enforces this
+at the `cache.put()` level. This is consistent with Chrome and Firefox
+behavior — the Cache API is designed for service worker contexts which
+only exist on HTTP/HTTPS origins.
+
+**Suggested fix:** None required — this is a fundamental WebKit/W3C
+specification restriction, not a sovereign_browser bug. Local-file web
+apps that need key-value storage should use IndexedDB instead, which
+works perfectly on `file://`.
+
+**Severity:** Low. Only affects apps specifically using the Cache API,
+which is a niche use case for local-file apps. IndexedDB is the
+recommended alternative and works fully.
+
+---
+
+## What Works Surprisingly Well
+
+These are the things that could have been broken but weren't:
+
+1. **Cross-origin access between all `file://` URLs** — iframes can access
+   their parent's DOM and vice versa, `window.open()` popups can be
+   accessed, and `fetch()`/XHR work across directories. This is the single
+   most important requirement for local-file web apps and it works
+   perfectly. WebKitGTK treats all `file://` URLs as same-origin.
+
+2. **Relative path resolution** — `../`, `../../`, and `../../../` all work
+   correctly for links, images, stylesheets, scripts, and fetch targets.
+
+3. **URL-encoded filenames** — `encoded%20name.html` (file on disk:
+   `encoded name.html`) loads correctly.
+
+4. **Query strings and hash fragments** — preserved in `location.href`,
+   accessible via `location.search` / `location.hash`, and don't break file
+   loading.
+
+5. **`history.pushState` / `replaceState`** — work on `file://` URLs,
+   allowing SPA-style routing for local apps.
+
+6. **All browser storage except Cache API** — `localStorage`,
+   `sessionStorage`, `cookies`, and `IndexedDB` all work fully on
+   `file://`. IndexedDB supports open, upgrade, object stores, put, get,
+   and count operations. Only the Cache API (CacheStorage) fails because
+   WebKit requires HTTP/HTTPS URLs for cache entries (Issue #5). Use
+   IndexedDB as the recommended storage for local-file apps.
+
+7. **`<picture>` / `srcset`** — responsive image selection works.
+
+8. **Form submissions** — both GET and POST navigate to the target local
+   file. GET appends query strings; POST silently drops the body (correct,
+   since there's no server).
+
+9. **Video and audio playback** — both MP4 video and M4A audio play
+   correctly from `file://` URLs. The `<video>` element reports correct
+   dimensions (640x360), duration (596.5s), and reaches `can play` state.
+   The `<audio>` element similarly works with correct duration. Media
+   playback is fully functional for local files.
+
+---
+
+## Recommended Actions
+
+### No blocking fixes needed
+
+The local-file browsing feature works well enough for production use as-is.
+The issues found are minor UX/engine-quirk issues, not functional blockers.
+
+### Optional improvements (in priority order)
+
+1. **~~Fix Issue #1 (about:blank on load failure)~~** — ✅ FIXED. The
+   failed URL now stays in the address bar, and the tab title shows the
+   error message.
+
+2. **Document the `fetch()`-throws-on-missing-file behavior** — Add a note
+   to the docs or a FAQ that `fetch()` on `file://` rejects (throws) for
+   missing files rather than returning an HTTP error response.
+
+3. **Document the Cache API limitation (Issue #5)** — Note in the docs that
+   the Cache API (CacheStorage) does not work on `file://` pages because
+   WebKit requires HTTP/HTTPS URLs for cache entries. Recommend IndexedDB
+   as the alternative for local-file apps needing structured storage. (Not
+   a real problem for local files since everything is already local — no
+   need to cache.)
+
+4. **~~Fix Issue #4 (title logging)~~** — ✅ FIXED. Added `notify::title`
+   handler; log now shows `[title] URL -- Title` when the title arrives,
+   and `[loaded] URL` without the noisy `title: (none)`.
+
+5. **Issue #2 (media error events)** — No action needed; upstream WebKit
+   behavior.
