This means: +- IDP logout redirects to `chrome-extension:///redirect/redirect.html` regardless of the website's client ID +- The website's Client ID Document should include the extension's redirect URI in its `post_logout_redirect_uris` if IDP logout is needed (impractical for general use since the extension ID is dynamic) +- **Pragmatic default**: App-only logout (clear local tokens) rather than IDP logout.

Keeping unverified code is technical debt. | +| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. | +| "Need to explore first" | Fine. Throw away exploration, start with TDD. | +| "Test hard = design unclear" | Listen to test. Hard to test = hard to use. | +| "TDD will slow me down" | TDD faster than debugging. Pragmatic = test-first. | +| "Manual test faster" | Manual doesn't prove edge cases. You'll re-test every change. | +| "Existing code has no tests" | You're improving it.

Use Stable Locators +```typescript +// ✅ Good - Role-based, stable +await page.getByRole('button', { name: 'Submit' }).click(); +await page.getByLabel('Email').fill('test@example.com'); + +// ❌ Bad - Fragile, implementation-dependent +await page.click('button.btn-primary.submit-btn'); +await page.fill('div > form > input:nth-child(3)'); +``` + +### 2. Leverage Auto-Waiting +```typescript +// ✅ Good - Auto-waits +await page.click('button'); +await expect(page.locator('.result')).toBeVisible(); + +// ❌ Bad - Manual waits +await page.waitForTimeout(2000); +await page.click('button'); +``` + +### 3. Use Page Object Model +```typescript +// ✅ Good - Reusable, maintainable +const loginPage = new LoginPage(page); +await loginPage.login('user', 'pass'); + +// ❌ Bad - Duplicated selectors +await page.fill('[name="username"]', 'user'); +await page.fill('[name="password"]', 'pass'); +``` + +### 4. Parallel-Safe Tests +```typescript +// ✅ Good - Isolated +test('user signup', async ({ page }) => { + const uniqueEmail = `user-${Date.now()}@test.com`; + await signUp(page, uniqueEmail); +}); + +// ❌ Bad - Shared state +test('user signup', async ({ page }) => { + await signUp(page, 'test@test.com'); // Conflicts in parallel +}); +``` + +### 5. Handle Flakiness +```typescript +// ✅ Good - Wait for network idle +await page.goto('/', { waitUntil: 'networkidle' }); +await expect(page.locator('.data')).toBeVisible(); + +// Configure retries +test.describe(() => { + test.use({ retries: 2 }); + + test('flaky test', async ({ page }) => { + // Test with auto-retry + }); +}); +``` + +## Common Patterns + +### Multi-Page Scenarios + +```typescript +test('popup handling', async ({ page, context }) => { + // Listen for new page + const popupPromise = context.waitForEvent('page'); + await page.click('a[target="_blank"]'); + const popup = await popupPromise; + + await popup.waitForLoadState(); + await expect(popup).toHaveTitle('New Window'); + await popup.close(); +}); +``` + +### Conditional Logic + +```typescript +test('handle optional elements', async ({ page }) => { + await page.goto('/'); + + // Close modal if present + const modal = page.locator('.modal'); + if (await modal.isVisible()) { + await page.click('.modal .close-button'); + } + + // Or use count + const cookieBanner = page.locator('.cookie-banner'); + if ((await cookieBanner.count()) > 0) { + await page.click('.accept-cookies'); + } +}); +``` + +### Data-Driven Tests + +```typescript +const testCases = [ + { input: 'hello', expected: 'HELLO' }, + { input: 'World', expected: 'WORLD' }, + { input: '123', expected: '123' }, +]; + +for (const { input, expected } of testCases) { + test(`transforms "${input}" to "${expected}"`, async ({ page }) => { + await page.goto('/transform'); + await page.fill('input', input); + await page.click('button'); + await expect(page.locator('.result')).toHaveText(expected); + }); +} +``` + +## Resources + +- [Playwright Documentation](https://playwright.dev/) +- [Best Practices Guide](https://playwright.dev/docs/best-practices) +- [API Reference](https://playwright.dev/docs/api/class-playwright) +- [GitHub Examples](https://github.com/microsoft/playwright/tree/main/examples) diff --git a/apps/extension/.claude/skills/playwright-e2e-testing b/apps/extension/.claude/skills/playwright-e2e-testing new file mode 120000 index 000000000..af1fd9079 --- /dev/null +++ b/apps/extension/.claude/skills/playwright-e2e-testing @@ -0,0 +1 @@ +../../.agents/skills/playwright-e2e-testing \ No newline at end of file diff --git a/apps/extension/.kiro/skills/playwright-e2e-testing b/apps/extension/.kiro/skills/playwright-e2e-testing new file mode 120000 index 000000000..af1fd9079 --- /dev/null +++ b/apps/extension/.kiro/skills/playwright-e2e-testing @@ -0,0 +1 @@ +../../.agents/skills/playwright-e2e-testing \ No newline at end of file diff --git a/apps/extension/e2e/setup/global-setup.ts b/apps/extension/e2e/setup/global-setup.ts index 3075ed045..660d331b4 100644 --- a/apps/extension/e2e/setup/global-setup.ts +++ b/apps/extension/e2e/setup/global-setup.ts @@ -1,9 +1,7 @@ import { startCSSServer } from './css-server';

Extractable keypair (documented: MV3 SW suspension loses a non-extractable key and breaks the jkt-bound refresh) persisted as JWK; round-trip re-import verified against the original public key. - core/origin-policy.ts — the per-origin credential boundary. computeAllowedOrigins / isOriginAllowed fail closed so pod A's token never attaches to origin B (the token-leak attack a malicious page would try via solid.fetch). Cleartext guard (https-only, http for loopback in dev). isTokenEndpoint pins "never attach the resource token to /token". - core/www-authenticate.ts — conservative RFC 9449 §8 use_dpop_nonce classifier + quote-aware WWW-Authenticate parser (mirrors @jeswr/solid-elements). The adversarial test 'rejects a foreign origin (the token-leak attack)' genuinely fails without isOriginAllowed's fail-closed check.

MV3 wiring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The page-facing + UI layer on the new message protocol: - inject.ts (MAIN world) — window.solid = { webId, fetch, setClientId, login, logout }. Holds NO credential; everything is a postMessage to the content bridge. The access-management SEAM (requestAccess?) is declared but throws "not implemented" so it is feature-detectable and addable later WITHOUT a breaking change — access management is the separate design-first track, deliberately out of scope here. - content-script.ts (ISOLATED world) — the trust boundary: stamps the REAL page origin (read here, not page-supplied) onto login + set-client-id so a page can't impersonate another origin's client-id mapping; relays fetch + state. - popup — the account UI built with @jeswr/solid-elements (jeswr-account-menu + jeswr-theme-toggle) for Pod-Manager-consistent look + dark mode; recent-accounts affordance, pod shortcut, a "restoring" state, and the first-run PIN nudge (extensions can't self-pin). Signed-out uses a native WebID form driving the worker login (the reactive-auth LoginController that jeswr-login-panel needs is SPA-popup-shaped; a chrome.identity-backed controller is a clean follow-up). popup.css declares the app-shell OKLCH tokens (light :root + .dark) so the chrome themes WITH the components; the filled button style is scoped to #login-form so it can't leak onto the shell controls. - manifest — drop the now-unused redirect web_accessible_resource + activeTab (chrome.identity handles the redirect internally); keep storage + identity + . v0.2.0. - build — webpack.config.cjs (the repo is ESM) + tsconfig.build.json (emit on); drop the redirect entry. The bundle carries NO node: imports (browser-safe core verified).

Now removes ONLY the side-panel id via chrome.contextMenus.remove(OPEN_SIDE_PANEL_MENU_ID, cb) (callback swallows the "not found" lastError on first run), still idempotent across SW restarts. - account-surface.ts (Low): the chrome.runtime.onMessage listener was never removed — harmless for the ephemeral popup, but the long-lived side panel would accumulate duplicate listeners + refresh() calls on remount. mountAccountSurface() now returns { controller, cleanup }: cleanup() detaches every listener it added (login/session-change/sign-out/onMessage) and is generation-fenced + idempotent. Added a WeakMap double-mount guard keyed on the host document. sidepanel.ts keeps the handle and calls cleanup() on `pagehide`; the popup ignores the return (short-lived). Tests: side-panel test asserts remove(own-id) and NEVER removeAll(); new account-surface-cleanup test asserts the listener detaches, cleanup is idempotent, and remount is guarded. Both genuinely fail without the fix (verified). Gate green: lint + typecheck + 133 tests + webpack build.

The problem in one paragraph + +The extension already brings Solid sign-in to the browser: it injects `window.solid` +(a DPoP-authenticated `fetch` + the WebID), holds the DPoP key + tokens ONLY in the +service worker (SW), and proxies every pod request through the SW behind a fail-closed +TARGET-origin credential gate. The refinement this doc designs is the **offline-first** +layer. The naive approach — give every Solid app a `@jeswr/solid-offline` service worker +— **duplicates the same pod data N times across N apps**, because browser Cache/IndexedDB +are partitioned by the visiting app's top-level site. We instead make the **extension own +ONE live, authenticated local replica per (user, pod), in the extension's own +`chrome-extension://` storage (NOT partitioned by the visited app's origin), SHARED across +every app, origin, and window.** The SW is the sole egress (sole DPoP-key holder) and the +sole offline-cache owner; WebSocketChannel2023 invalidation runs ONCE centrally. The +consequence is that **per-origin access control becomes load-bearing**: one shared replica +means any app could otherwise read the whole pod, so the extension MUST enforce which app +may read/write which data at the browser boundary — the runtime home for the tt6 data-class +consent model. + +## 1. Per-origin duplication — the problem this removes + +Verified against Chrome's [Storage and cookies](https://developer.chrome.com/docs/extensions/develop/concepts/storage-and-cookies) +and [Storage Partitioning](https://developer.chrome.com/en/docs/privacy-sandbox/storage-partitioning/) +docs: + +- A normal web page's `CacheStorage` + `IndexedDB` are **partitioned by the top-level + site**.

In the extension partition +there IS no origin boundary underneath. So the cache key MUST include the active **WebID** +(and the grant-scope, §4), and every read MUST verify the active-WebID namespace, never just +the ETag — otherwise a same-URL+same-ETag collision across two users on one device (a shared +or public resource, or a re-provisioned WebID) serves user A's bytes to user B. + +### 2.2 Consistency model + +Read-from-cache + always-revalidate (never-authoritative stale-while-revalidate), reusing +`@jeswr/solid-offline` `swr.ts`.

The optimistic-mutation UX invariant is delivered at the **app layer** (the app paints + immediately, shows Saving/Saved) over a write-through that confirms; the replica stays + coherent. + +**MV3 write-visibility caveat (review finding).** The SW can be suspended AFTER the pod 2xx +but BEFORE step 3 persists+broadcasts. The write is not lost (the pod has it) but cross-app +visibility is not atomic with the write; other apps see it on next revalidation / WS frame. +Convergence is eventual, not instant — never-authoritative-revalidate keeps it *correct*. + +**Offline write QUEUE is an explicit Phase-3 deferral** (matches tt6 + solid-offline both +deferring offline writes): a durable per-resource outbox replayed on reconnect must (a) be +keyed by the unforgeable requesting origin, (b) **re-check the grant at replay time** (a +grant may have been revoked between enqueue and replay), and (c) surface a 412 on replay, +never auto-merge. Do not ship until that conflict+revocation path is built. + +## 3. The three routing mechanisms compared + +| Mechanism | Can carry per-request DPoP at egress? | Can serve a replica body? | Boot-race? | Blocks cross-app leak? | Verdict | +|---|---|---|---|---|---| +| **MAIN-world global-fetch patch → ISOLATED bridge → SW** (RECOMMENDED) | **Yes** — the SW signs each proof; key never leaves SW | **Yes** — SW returns a serialized Response | Patch is racy + bypassable (verified), so it is **transparency only, zero security weight** | **Only if** the SW enforces a per-requesting-origin default-deny gate (the graft below) | **Recommended** | +| **declarativeNetRequest redirects the pod request to the SW** | **No** — DNR has no JS callback, cannot carry/sign a per-request proof | **No** — DNR cannot synthesize/modify a response body; redirect drops method+body | Race-free (installed before page scripts) but unusable as a data path | n/a — cannot route at all | **Infeasible as router** (3 verified blockers) | +| **DNR as a fail-closed bypass backstop** (defense-in-depth) | n/a | n/a | Race-free | **No** — cannot cleanly exempt the SW's own egress while blocking page bypass | **Best-effort observer only, never relied on** | + +**Verified facts behind the table** (Chrome for Developers, June 2026): + +- MAIN-world `document_start` content scripts are **NOT guaranteed to run before the page's + own inline scripts** (inline scripts are parser-blocking; src scripts are not) — so a page + can capture pristine `fetch` first. ([content-scripts manifest doc](https://developer.chrome.com/docs/extensions/reference/manifest/content-scripts), [chromium-extensions thread](https://groups.google.com/a/chromium.org/g/chromium-extensions/c/eVZd_vOIryc)) +- `declarativeNetRequest` **cannot modify response bodies** (headers only), a redirect target + must be a static web-accessible resource (no JS callback), and **it DOES affect `fetch()` + made in a service worker** — so the extension SW's own legitimate pod egress is itself + subject to a pod-host DNR rule. The only way to exempt it (`excludedInitiatorDomains` / + tabId -1) **also stops the rule matching website-service-worker-initiated requests**, so a + malicious page can bypass the backstop via its own page SW. ([declarativeNetRequest API](https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest)) The backstop is therefore NOT reliably fail-closed; the real guarantee must not depend on intercepting page traffic. + +## 4. Security findings + +### 4.1 Cross-app data leak — the headline (CRITICAL as code stands today) + +All three adversarial reviews landed the same break against the ACTUAL code: + +- `service-worker.ts` `handleFetch(message)` consumes `message.url/method/headers/body` and + **ignores `_sender`** (line 253). There is no per-requesting-origin authorization. +- `content-script.ts` forwards the fetch with **no origin stamp** (lines 39-53); it stamps + `window.location.origin` only for `SOLID_LOGIN` / `SOLID_SET_CLIENT_ID`. +- The only gate (`origin-policy.ts` `isOriginAllowed`) is about the **TARGET pod** ("don't + send the token to evil.com"), not the **requesting app**. +- `inject.ts` `requestAccess()` **throws "not implemented"** (lines 138-145). +- The cache key has **no app/origin dimension**; `manifest.json` injects `window.solid` on + ``. + +So **today any origin can call `window.solid.fetch(podUrl)` and read/write the whole pod.** +That is tolerable in the current single-user product (no shared replica, no per-app promise), +but it is FATAL the instant a shared replica exists. **`crossAppLeakBlocked = false` as +written.** This is a pre-existing exposure worth a tracked security bead on +`solid-browser-extension` regardless of the shared-replica work. + +### 4.2 Key custody — the strongest property (PRESERVED, do not touch) + +Refuted by all reviewers. The DPoP keypair lives only as JWK in `chrome.storage.local`, +reachable only from extension contexts; `createDpopProof` (`dpop.ts`) exports ONLY the +public components (kty/crv/x/y, never `d`); the page receives only a WebID + a reconstructed +Response; page-supplied `Authorization`/`DPoP` headers are stripped (`authenticated-fetch.ts` +`HOP_BY_HOP`). Residual LOW: the key is generated **extractable** (an MV3 necessity — a +non-extractable key is lost on SW suspension, breaking the jkt-bound refresh) and co-located +with the refresh token in `chrome.storage.local`, so any extension-context compromise +exfiltrates both from one store. Not page-reachable; a concentrated single point worth noting. + +### 4.3 Other verified findings (graft the mitigation into the recommendation) + +- **Forge the access-control anchor.** `sender.origin` is renderer-spoofable; the + content-script stamp is read in the same renderer. Mitigation: default-deny + SW-sole- + enforcement so a forged origin only reaches THAT origin's grants; require BOTH anchors to + agree; never trust a page/bridge-supplied origin FIELD — read `chrome.runtime` `sender`. +- **Boot-race / page-SW / XHR bypass.** Fail-safe for the credential (a bypassed request is + unauthenticated → pod 401), but can reach PUBLIC pod data. Mitigation: server-side WAC is + the ultimate boundary; the SW gate + the (best-effort) DNR observer are layers, not the + guarantee. +- **Cross-USER stale bytes.** `logout.ts` purge is async/best-effort and MV3-interruptible; + the WebID-omitted cache key collides. Mitigation: WebID in the key + **synchronous-before- + serve purge** (block a new session's reads until the prior identity's stores are fully + dropped). +- **Refresh-token rotation across SW suspension.** A mid-refresh kill can burn the rotation- + bound refresh token (DoS). Mitigation: persist the rotated token atomically BEFORE use; the + existing `refreshGate` single-flight is in-memory and must be re-derivable on wake. +- **resolveClass widening (tt6 §6.2).** A pod-controlled Type Index / SHACL shape can widen a + data-class grant. Mitigation: SHACL-validate at resolution; pin the exact shape IRI at + consent; read-only Phase-1; write-by-class pins explicit targets. +- **Foreign-origin fetch ambient cookies.** `window.solid.fetch('https://tracker/')` is run + by the SW as a plain fetch carrying extension-context ambient cookies (CSP-free tracking + amplification). Mitigation: same-origin-or-deny policy for foreign SW fetches. +- **PII broadcast.** The WebID (and any pod-origin allowlist) is pushed to every script on + ``. Mitigation: scope presence/WebID to apps that opt in. + +## 5. Recommended architecture (implementable) + +### 5.1 Routing + +PRIMARY = **MAIN-world global-fetch patch → ISOLATED bridge → SW**, a generalization of the +existing `window.solid.fetch` proxy: + +- In `inject.ts`, in addition to defining `window.solid`, install a global wrapper anchored + on the captured pristine fetch: + `const real = window.fetch; window.fetch = (i,init) => isPodUrl(i) ? solidFetch(i,init) : real(i,init)`. + Reuse the `@jeswr/solid-elements` `installProactiveAuthFetch` discipline (snapshot the + pristine fetch, build once, re-assert ownership, never re-read a possibly-patched global), + but its `base` transport is the postMessage→SW bridge, NOT a page-side authenticated fetch. +- `isPodUrl` diverts only known pod origins; everything else hits the untouched native fetch + (no proxy tax, no breakage of unrelated requests). Do NOT broadcast the full pod-origin + list to the page (PII); use a minimal predicate or route everything and let the SW gate + decide. +- **Register the MAIN-world script programmatically from the SW** + (`chrome.scripting.registerContentScripts({world:'MAIN', runAt:'document_start', + persistAcrossSessions:true})`) — the most reliable MAIN injection (the MetaMask + `window.ethereum` pattern). +- **The patch is best-effort transparency with ZERO security weight.** It is racy and + bypassable (verified). A missed/bypassed request is a plain unauthenticated fetch (pod 401, + fail-safe for the credential) and the server's own WAC governs what it returns. +- DNR is retained ONLY as a best-effort defense-in-depth observer/blocker; it is NEVER the + router and NEVER relied on as fail-closed (its self-egress exclusion hole is verified). + +### 5.2 Replica + key in the SW + +As §2: bytes in `CacheStorage`, metadata in `IndexedDB`, key+session+grants in +`chrome.storage.local`, nonce cache moved to IndexedDB; cache key includes WebID + grant- +scope; everything re-hydratable on SW wake (no load-bearing in-memory state). + +### 5.3 Egress DPoP (preserve verbatim — strongest property) + +The SW is the SOLE egress and SOLE key holder. Per-request signing via the existing +`createDpopProof` (Web Crypto + jose; ES256; public-only `jwk` header; `htm/htu/iat/jti`; +`ath` = base64url(SHA-256(token)); §8 nonce echoed on challenge), one §8 nonce retry with a +per-origin nonce cache, exactly-one retry. Proactive refresh ~30s before expiry, single- +flighted via `refreshGate`, same keypair reused so the pod `jkt` binding holds. Refresh-token +persistence + the fail-closed silent-restore decision reuse `@jeswr/solid-session-restore`. +The page only ever receives a WebID + a proxied Response. (Note: the live PSS RS runs +`allowMissingAth` compat, so end-to-end token-binding at the RS is weaker than the proof +shape implies — orthogonal to the extension but relevant to the PoP story.) + +### 5.4 Per-origin default-deny access control + the tt6 data-class hook + +THE load-bearing graft. Enforced in the SW, BEFORE any cache hit or egress, on every read, +**every cache hit**, and every write: + +1. **Forward + enforce the true requesting origin on EVERY fetch.** Change the + `SOLID_FETCH_REQUEST` relay to stamp `window.location.origin` (as it already does for + login), AND have `handleFetch` read `chrome.runtime` `sender.origin` (browser-attested). + Both must agree. **Never** trust a page-supplied origin field. **Fail-closed on + opaque/null origins** (sandboxed iframe, `srcdoc`, `about:blank`, `data:`) — never a + shared "null" bucket. +2. **Default-deny.** Resolve `(origin, target-URL, method) → grant decision`. No grant ⇒ the + SW returns a 403-equivalent WITHOUT touching the replica or the pod (so the shared replica + cannot serve cached private bytes to a non-consented app). NOT sent unauthenticated. +3. **Re-check the gate on cache HITS, not just egress** — the central authenticated + revalidation lands bytes in one replica that multiple un-equal-trust origins can read, so + the gate must mediate every read of the shared bucket. Partition the cache by grant-scope + so a missing grant cannot even reach a shared body. +4. **tt6 data-class hook = the policy source.** The gate consults a per-origin grant store + whose grants are tt6 `accm:`/SAI `AccessGrant` records resolved to concrete targets via + the tt6 ladder (`accm:resolvesTo`: SAI `interop:DataRegistration.registeredShapeTree` → + Type-Index `solid:instanceContainer` → **SHACL-validate**). "This app may read finance + data" compiles to "origin X may read {container set Y}". Consent UI renders in EXTENSION + chrome (popup/side-panel), unspoofable by the requesting origin; the grant is bound to the + content-script-stamped+sender-attested true origin. The `window.solid.requestAccess` seam + (today a throwing stub) is wired to `requestAccess`/`listGrants`/`revokeGrant`/ + `resolveClass`. +5. **Read-only Phase-1 grants**; write-by-class pins exact targets (tt6 §2.3 — never let an + app-influenced class definition broaden its write surface). **Revocation must invalidate + already-served/replica bytes + any queued writes, not just future fetches.** + +### 5.5 Offline-first + WS invalidation (the inversion) + +Reuse `@jeswr/solid-offline` modules INVERTED for the authenticated extension SW: + +- Verbatim: `swr.ts` (never-authoritative SWR), `cache-coherence.ts` (synthetic-key keying), + `metadata-store.ts`, `invalidation.ts` (WS-frame → revalidate-or-purge with the ETag self- + write short-circuit). +- **The inversion:** `solid-offline`'s SW is UNAUTHENTICATED by design — `notifications.ts` + states verbatim "THE WEBSOCKET LIVES IN THE PAGE (decision 5), NEVER THE SW … the SW only + invalidates." In the EXTENSION the SW IS the authenticated owner, so (a) the injected + `fetch` port given to swr/invalidation is the AUTHENTICATED DPoP egress (private resources + revalidate, not 401), and (b) the WebSocketChannel2023 subscription lives in the EXTENSION + SW — ONE socket per pod container for ALL apps. This re-opens `solid-offline`'s threat model + (authenticated subscribe POST + one-socket-per-pod fan-out) and **needs its own audit before + reuse** — flagged, not assumed safe. Discovery + subscribe use the suite + `solid-notifications` path; the notification `state` field === the resource ETag (the join + invalidation already exploits). A central invalidation broadcasts to every tab so all apps + re-render. + +### 5.6 MV3 persistence + +- The MV3 SW is terminated after ~30s idle (verified) — durable state must survive: bytes + (Cache), metadata + nonce (IndexedDB), key+session+grants (`chrome.storage.local`). On + every wake re-open handles + rebuild in-memory nonce/single-flight lazily. +- The WS does NOT survive suspension. A live WS extends SW lifetime (Chrome 116+: WS + send/receive resets the idle timer — verified), but Chrome still reclaims on memory + pressure. On every wake run `resyncSweep` (conditional-revalidate the warmed set) then + re-subscribe; a `chrome.alarms` heartbeat (min 30s) re-asserts subscriptions + sweeps. + Reads are never-authoritative, so a momentarily-missed invalidation is one stale-then- + revalidated read, never a wrong write. + +### 5.7 Trustworthy presence signal + +- Presence = `window.solid` present + `window.solid.webId` + a `solid:ready` CustomEvent + + a frozen capability handshake `{present:true, version, capabilities:['fetch', + 'globalFetchPatch','accessControl','sharedReplica']}`. `window.solid` is installed with + `Object.defineProperty(window,'solid',{configurable:false})` (already done) so a later page + script cannot replace it. +- **Presence is a UX/cooperation signal, NOT a security boundary** — a page can pre-define a + fake `window.solid` (boot race) to lie to its own scripts, but gains no cross-origin trust + and no data (the SW gate is the boundary; a forged presence cannot mint a DPoP proof). The + only TRUE presence proof is capability: a successful DPoP-authed pod read the page did not + supply a token for. +- Apps use presence to skip their own login and hide their own profile chrome; the pinned + toolbar avatar is the user-facing signal. **Scope the WebID broadcast to opt-in apps**, not + every script on `` (PII). + +## 6. Coupling to tt6 (access-management) — what ships first + +- **Ships BEFORE access-mgmt lands — owner-only single-user default.** The extension's strong, + already-built single-user mode: ONE user, the existing per-user pod-origin allowlist as the + grant store, the SW as sole key holder + egress, the DPoP egress preserved. In this mode + there is no cross-app boundary to enforce because there is effectively one trust principal + (the owner) and a coarse per-pod allowlist — which is exactly why the **shared replica must + NOT be turned on in this mode** (a coarse per-pod-origin grant is per-USER, not per-APP, so + it provides NO cross-app isolation). Ship offline-first per-app-cache OR single-user only + until the gate lands. +- **What the browser-side enforcement needs from tt6 (the access-mgmt design):** the + `client→consent→grant` RUNTIME — a per-origin grant store keyed by `(requesting-origin → + data-class → mode → expiry)`, resolved to concrete targets via `accm:resolvesTo` (SAI + DataRegistration → Type Index → SHACL-validate). The extension is tt6's browser-side + enforcement point: it authors SAI/ACL grants as ordinary authenticated writes (no server + change for read grants) and gates every routed request against the resolved grant set. +- **What tt6 sequences AFTER (CORE-PSS, maintainer-gated):** the server-native Authorization + Agent + request-inbox (LDN) + class→target resolver + WAC/ACP materialisation for the + seamless, scalable flow. The extension can do client-side class→target resolution today; + server help is wanted for materialization at scale. **tt6 itself sequences the extension + consent path LAST and flags the confused-deputy mislabelling attack as open** — so the + shared replica is gated behind the per-app/per-data-class grant store, not the coarse store. + +## 7. Phased build plan + +The non-negotiable ordering: **build the boundary, prove it adversarially, THEN turn on the +shared replica.** + +- **Phase 0 — Hardening prerequisite (security-critical; build + prove FIRST).** Forward the + true requesting origin on every `SOLID_FETCH_REQUEST` (content-script stamp + `sender` + cross-check); add a SW default-deny per-origin gate as the FIRST check on read/cache-hit/ + write; fail-closed on opaque/null origins; add the same-origin-or-deny foreign-fetch policy; + stop broadcasting the pod-origin allowlist + scope the WebID to opt-in. Adversarial tests: + forged `sender.origin` → DENY, whole-pod read by an ungranted origin → DENY, app-A requests + app-B-only resource → DENY, opaque-origin → DENY, race the boot patch → fail-safe. Land this + on the single-user product BEFORE any replica work. File the pre-existing `` + full-pod-exposure security bead. +- **Phase 1 — Shared-replica + routing + egress-DPoP core (behind the Phase-0 gate).** The + global-fetch patch (programmatic MAIN injection); the `(WebID, pod-origin, grant-scope)`- + keyed replica in `CacheStorage`+`IndexedDB`; nonce cache → IndexedDB; synchronous-before- + serve logout purge + atomic rotated-refresh-token persistence; preserve the DPoP egress + verbatim. Read-from-cache+revalidate; synchronous write-through. Re-check the gate on cache + hits. +- **Phase 2 — Per-origin access-control enforcement + tt6 data-class hook.** Wire + `window.solid.requestAccess`/`listGrants`/`revokeGrant`/`resolveClass` to the tt6 grant + store; consent UI in extension chrome bound to the true origin; SHACL-validate `resolveClass`; + read-only class grants; revocation invalidates served/replica bytes. +- **Phase 3 — `@jeswr/solid-offline` central sync.** WebSocketChannel2023 subscription in the + SW (one per pod container), authenticated revalidation, central invalidation broadcast, + `resyncSweep` + `chrome.alarms` heartbeat on wake. **Re-audit `solid-offline`'s + notifications/invalidation under the inverted (authenticated-SW) threat model before reuse.** + (Offline write QUEUE is deferred past v1 — see §2.3.) +- **Phase 4 — Consolidate the 10 apps onto `` with hide-when-extension- + present.** Standardise the suite apps (7 pod-apps + PM + solid-issues + app-store) on the + Lit `@jeswr/solid-elements` `` (exists; `webid` attribute), feature- + detecting `window.solid` + the `solid:ready` capability handshake to suppress the app's own + login/profile chrome and defer to the extension identity. Add a `hide-when-extension-present` + capability to the element. Update the `create-solid-app` template to standardise the check. +- **Phase 5 — Playwright-with-extension tests vs a LOCAL Solid server.** E2E with the + unpacked extension loaded (`--load-extension`, persistent context), pointed at a **local + CSS / local `prod-solid-server` (`docker compose up`), never the live deploy** (house rule). + Cover: cross-app read+write denial (two app origins, one pod), forged-origin denial, cross- + user purge race, boot-race fail-safe, single-replica-shared-across-origins, offline-load- + from-cache, central WS invalidation. Use the `playwright-best-practices` / + `solid-test-infrastructure` skills. + +## 8. What needs CORE-PSS server changes (maintainer approval, separate) + +The tt6 server-native Authorization Agent (request-inbox LDN endpoint, class→target +resolver, WAC/ACP materialisation) is new security-critical surface on `prod-solid-server` +(`src/access-requests`, touching `src/authz`). It goes through auth-specialist + +storage-specialist + the conformance harness + roborev, and needs maintainer approval. The +extension's shared-replica + per-origin gate + client-side grant authoring need **no** PSS +server change; they work against any spec-conformant Solid server today, with server-side WAC +as the ultimate enforcement backstop. + +## Appendix — Sources (verified June 2026) + +- [Chrome: content scripts manifest (MAIN-world / document_start)](https://developer.chrome.com/docs/extensions/reference/manifest/content-scripts) +- [chromium-extensions: MV3 MAIN-world injection ordering](https://groups.google.com/a/chromium.org/g/chromium-extensions/c/eVZd_vOIryc) +- [Chrome: declarativeNetRequest API (body/redirect/SW-fetch limits)](https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest) +- [Chrome: Storage and cookies (extension origin not site-partitioned)](https://developer.chrome.com/docs/extensions/develop/concepts/storage-and-cookies) +- [Chrome: Storage Partitioning](https://developer.chrome.com/en/docs/privacy-sandbox/storage-partitioning/) +- [Chrome: service worker lifecycle (~30s idle; Chrome 116 WS keepalive)](https://developer.chrome.com/docs/extensions/develop/concepts/service-workers/lifecycle) +- [RFC 9449 DPoP](https://www.rfc-editor.org/rfc/rfc9449.html) · [RFC 9068](https://www.rfc-editor.org/rfc/rfc9068.html) +- In-repo: `solid-browser-extension/src/{inject/inject.ts,content/content-script.ts,background/service-worker.ts,background/core/{origin-policy.ts,authenticated-fetch.ts,dpop.ts}}` +- In-repo: `solid-offline/src/{scope.ts,notifications.ts,logout.ts,swr.ts,cache-coherence.ts,metadata-store.ts,invalidation.ts}` · `solid-elements/src/{auth/proactive-fetch.ts,components/account-menu.ts}` +- tt6: `full-solid-ecosystem/docs/design/access-management-solid-lws.md` \ No newline at end of file From 3aec8dda2405cafd5e7bd7b49bb56fc970232389 Mon Sep 17 00:00:00 2001 From: Jesse Wright <63333554+jeswr@users.noreply.github.com> Date: Sun, 21 Jun 2026 16:15:34 +0100 Subject: [PATCH 27/50] feat(auth): Phase-0 SW default-deny per-requesting-origin gate + close full-pod over-exposure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Security-critical hardening on the existing single-user owner product, BEFORE any shared-replica work (design §Phase 0). Makes the per-origin credential boundary fail-closed + browser-attested and stops over-broadcasting identity. - New `src/background/core/requesting-origin.ts`: the pure, exhaustively-tested gate. `resolveRequestingOrigin` requires the browser-attested `sender` origin (or origin of `sender.url`) and the content-script `window.location.origin` stamp to AGREE — a forged stamp only ever denies. `decideRequestingOrigin` runs the full fail-closed decision: dual-origin agreement → default-deny per-origin grant → same-origin-or-deny foreign fetch. Opaque/null/`about:blank`/`data:`/`file:`/`srcdoc` → DENY (no shared "null" bucket). - Wired into `service-worker.ts` `handleFetch` as the FIRST check before any pod egress or cache read: the cheap dual-origin/opaque half runs before `ensureSession()` (so a forged/opaque origin can't even cause a refresh side effect), then the grant + foreign- fetch half. Grant set is re-read from durable storage every request → cold-wake/boot-race is fail-CLOSED (empty store denies all). - Grant store in `session-store.ts` (`solid:granted-origins`): default-deny; the owner opts an app in by a deliberate browser-attested action (login / setClientId) FROM that origin; session credential (pod/WebID/issuer) origins are auto-granted requesters. - Close the PII over-exposure: `SOLID_GET_STATE` returns the WebID only to a verified, granted page (extension popup/side-panel get full state); `broadcastStateChange` reveals the WebID only to granted tabs.

Now classifySenderOrigin distinguishes ABSENT (undefined/null/empty → may derive from sender.url) from PRESENT-but-OPAQUE ("null"/unparseable/non-http(s) → DENY immediately, no url fallback). Legit cases preserved: real https sender.origin, absent-origin url fallback, blob:-resolves-to-creator-origin. High #2 (service-worker.ts handleLogin): grantOrigin was called BEFORE initiateLogin, so any page could send SOLID_LOGIN, get its origin persisted as granted even if the auth flow cancelled/failed, then ride an existing session via SOLID_FETCH_REQUEST (privilege escalation). The verified requesting origin is now resolved BEFORE login (to bind the flow) but grantOrigin is moved to the success path — a cancelled/failed login leaves the grant store unchanged. Adversarial tests added (205 total, all green): present-opaque sender.origin denies with no url fallback (pure + wired, no egress); absent-origin url fallback still resolves; failed/cancelled login persists no grant and a subsequent fetch is denied even when a session exists; successful login grants + fetch succeeds; forged login origin not granted even on success. Gate: lint + typecheck + 205 tests + build all green.

Builds the five Phase-1 pieces; Phases 2-4 (per-app/data-class consent, central WS sync, app consolidation) are NOT built. 1. MAIN-world global-fetch patch → ISOLATED bridge → SW routing (inject.ts global `fetch` wrapper anchored on the pristine fetch + programmatic `chrome.scripting.registerContentScripts` world:MAIN run_at:document_start persistAcrossSessions). BEST-EFFORT TRANSPARENCY, ZERO security weight — every routed request still goes through the Phase-0 gate as the FIRST check. 2. ONE shared replica per (WebID, pod-origin) in the extension's own storage: bytes → CacheStorage, metadata → IndexedDB (replica-db.ts), keyed on a SECURITY-SCOPED synthetic key that embeds the active WebID + grant-scope (replica-key.ts — the design's LOAD-BEARING CACHE-KEY FIX; solid-offline's scope hash is NOT a security boundary in the single extension partition). Read-from-cache + revalidate (never-authoritative SWR); synchronous write-through with If-Match (replica.ts). 3. Re-check the Phase-0 gate on EVERY cache HIT — the gate is an injected predicate the replica awaits as the FIRST step on every read AND write; no code path serves a cached body before the gate resolves to ALLOW. 4. DPoP nonce cache moved from the in-memory Map to IndexedDB (survives SW restart); synchronous-before-serve logout purge (replica bytes + metadata + nonces dropped before any further serve); atomic rotated-refresh-token persistence + the refreshGate single-flight PRESERVED. The DPoP egress + key-in-SW custody are PRESERVED VERBATIM (authenticated-fetch.ts and dpop.ts unchanged). 5. Single-user owner-only: serves only the Phase-0 granted origins; no cross-app/data-class logic (window.solid.requestAccess remains the throwing stub). Adversarial tests (34 new, all 205 Phase-0 tests still green): shared replica serves the same bytes across two granted origins (no dup); a cache HIT still enforces the origin gate (un-granted origin DENIED on a warm cache, no egress); write-through with If-Match; synchronous logout purge; SW-restart nonce restore from IDB; cross-user cache-key guard (same URL+ETag, different WebID → not served).

All fixed, with adversarial tests. High #1 — global-fetch over-divert broke non-pod web traffic. The inject diverted EVERY cross-origin http(s) fetch into the gated path, so an app's calls to third-party APIs/CDNs were DENIED (403) as unauthenticated. Decision (option b — keep the inject DUMB, the SW the boundary): the inject routes everything but marks the request `autoDivert: true`; the SW NATIVE-PASSES-THROUGH (plain unauthenticated fetch, no token, no replica) for any non-ALLOW gate decision instead of a 403, so normal web traffic is never broken and access can never widen (a native fetch carries no credential). The credential/replica path is taken ONLY on an explicit gate ALLOW (known pod origin from a granted requesting origin). An explicit window.solid.fetch (autoDivert false) keeps the 403. Applied at every SW exit: gate deny, forbidden/opaque origin, and no-session. Medium #2 — double injection. inject.js was BOTH manifest-declared and dynamically registered → could run twice and throw on the configurable:false defineProperty. Removed the manifest MAIN-world declaration (dynamic registerContentScripts is now the single path) AND added a `window.__solidInjected`/`'solid' in window` idempotency guard so a double-run is an inert no-op regardless. Medium #3 — a non-cacheable 2xx (206 / Vary:*) broke the request when cache.put rejected. Caching is now best-effort: cache.put + metadata write are wrapped in try/catch, the live response is cloned up-front and returned regardless of persist failure. Medium #4 (privacy) — the null-WebID logout purge cleared metadata but left CacheStorage bytes. Added cache-key enumeration (ReplicaByteCache.keys(), defaulting to cache.keys()); the null purge now deletes all replica byte entries, so bytes + metadata + nonces are all gone on an unknown-prior logout/reset. Low #5 — HEAD returned a body (the cached GET body on a 304, or a pod's stray HEAD body). A HEAD response is now body-stripped on every served path (304 cache hit, live egress) in the replica and in the SW relay.

The Medium: header-stripping + credentials:'omit' also changed normal fetch semantics for legit third-party calls. The fix resolves BOTH: the SW NEVER performs a fallback fetch. For an autoDivert request the gate does NOT allow (gate-deny, forbidden/opaque early reject, AND no-session), the SW returns a PASSTHROUGH SENTINEL ({ requestId, passthrough: true } — no body, no status, no fetched bytes, ZERO network). The page-side inject completes the request with its OWN captured PRISTINE_FETCH using the ORIGINAL input/init, in the page's origin context — so CORS / credentials / headers are exactly native. The authenticated/replica path is unchanged (runs only on an explicit gate ALLOW); an explicit window.solid.fetch still gets its 403 / Not-authenticated (never a sentinel). - src/background/service-worker.ts: DELETE nativePassthrough + PASSTHROUGH_STRIP_HEADERS; add passthroughSentinel(); all three non-allowed autoDivert branches return it (no fetch). - src/shared/messages.ts: add FetchResponse.passthrough?: boolean (+ doc). - src/content/content-script.ts: relay the passthrough flag verbatim (already spread). - src/inject/inject.ts: pendingFetches retains original input/init; capture PRISTINE_FETCH at the top of installSolidInjection; on passthrough:true resolve via PRISTINE_FETCH(orig). - tests: SW gate now asserts sentinel + NO SW egress on non-allowed autoDivert; new cross-origin-proxy security test; inject test for the PRISTINE_FETCH passthrough path. Keeps all Phase-0/1 invariants (gate-first incl. cache hit, WebID-in-key, DPoP egress untouched, single-user, byte-purge enumerator, HEAD bodyless, best-effort cache).

Snapshot input (a mutable URL), init, and headers at call time so a page mutating those objects between the call and the sentinel cannot change the eventual native passthrough request. roborev 373c80e Medium. +1 mutation-immunity test; existing passthrough test updated to assert a value-equal snapshot (not reference identity). Detect a URL by cross-realm-safe duck-typing (urlLike: a non-null object with a string href) instead of `instanceof URL`, and snapshot the input to its href STRING. `instanceof URL` is unreliable across JS realms (an iframe, or a JSDOM URL vs the module's bare-global URL) — a foreign-realm URL would be mis-classified as same-origin and skip the gate. A string snapshot is fully specified, immutable, and accepted identically by native fetch in browser and JSDOM, so the mutation-immunity + divert behaviour is correct in both. Fixes the failing test/inject.test.ts mutation-immunity case.

Presence announce (inject.ts): on install, set a sticky `` marker + dispatch a one-shot `solid-extension:ready` event. Both are credential-free (presence only; webId stays on window.solid, null until auth). The marker is readable synchronously by app code regardless of load order; the event covers a listener attached before inject ran. 2. Reliable injection (manifest.json): re-declare inject.js as a manifest MAIN-world content script (document_start). The dynamic `chrome.scripting.registerContentScripts` path only takes effect once the MV3 SW has run to register it — a dormant SW on a cold page load leaves window.solid undefined until something wakes it (root-caused via a Playwright persistent-context spike: onInstalled registration was absent, storageKeys empty, window.solid never appeared). The manifest declaration runs at document_start on every navigation with no SW-wake dependency.

Route all three through a single promise-chain serialiser that re-reads inside the critical section. - MEDIUM: resolveClass let any class-only origin enumerate targets for ANY class (private-structure leak). Now a class-only origin may resolve ONLY a class it holds a live grant for; full-grant origins keep open introspection. - Defence in depth: the resolver no longer fetches a type-index ref on a foreign origin (a hostile profile pointing publicTypeIndex at an attacker URL could turn resolution into an SW-side SSRF) — off-pod refs are skipped. - +4 tests: concurrent save+revoke no-resurrect, resolveClass class-scoped allow/deny, full-grant open resolve, SSRF ref-skip.

That is DELIBERATE: unconditionally removing it would drop the pod origin in the ubiquitous CSS single-origin topology (WebID + IdP on ONE origin) and break class resolution entirely. The `includeIssuerOrigin: false` rule already achieves the correct policy — the issuer origin is allowed ONLY when it coincides with a genuine pod origin (WebID origin or a user-configured pod), where token-to-that-origin is already normal pod access (and the token endpoint stays protected by isTokenEndpoint); an issuer origin DISTINCT from every pod origin (the profile-controlled vector) is excluded. - Expanded the rationale in podOriginsFor. - +1 test: CSS single-origin (WebID origin === issuer origin) — a same-origin type-index ref IS followed so resolution works (proving no over-exclusion); the distinct-issuer skip is already covered.

Non-extractable CryptoKeys are structured-clone serialisable, so the key survives the MV3 service worker's aggressive kill/restart cycle without ever being exportable — closing the F3 keystore-advantage finding from the design review while keeping the same session-scoped-keypair behaviour (fresh key per login, reused across refreshes, cleared on logout). - core/dpop.ts: generateDpopKeyPair() now generates extractable:false; removed exportDpopKeyPair/importDpopKeyPair/StoredDpopKeyPair (no longer needed — the key is never exported to JWK for storage). - core/dpop-key-db.ts (new): IndexedDB handle for the keypair record (put/get/clear), modelled on replica-db.ts. - core/dpop-key-store.ts (new): mintAndPersistDpopKeyPair (login) and loadOrRotateDpopKeyPair (reload-or-mint) orchestration. - session-store.ts: StoredSession no longer carries dpopKeyPair; loadSession() detects + strips a pre-hardening inline extractable JWK on read (one-time migration) and writes the cleaned record back immediately. A migrated session's refresh token was DPoP-bound to the old key's jkt and will fail its next refresh, which the existing refresh-failure teardown in ensureSession() already turns into a clean re-login — no new complexity needed there. - auth-flow.ts / service-worker.ts: rewired onto DpopKeyDb + loadOrRotateDpopKeyPair; logout now also clears the persisted key. Tests: dpop.test.ts (non-extractability + still-signs-and-verifies), dpop-key-store.test.ts (new — a real DpopKeyDb against a minimal fake IDBFactory proving the structured-clone round trip, not a mocked module), session-store.test.ts (new — the legacy-migration strip + idempotency), and the three service-worker integration suites updated to seed the fake DpopKeyDb instead of embedding dpopKeyPair on StoredSession fixtures. +11 net new test cases (358 total).

Model: claude-sonnet-5 Co-Authored-By: Claude Sonnet 5 * fix(auth): roborev round-1 — dpopJkt-checked key load + defer persist to login success Two Medium findings from codex's review of b64367d, both closed: 1. loadOrRotateDpopKeyPair() silently minted a fresh key whenever IndexedDB was empty, even for a CURRENT-shape session whose access/refresh tokens were bound to a different (lost/evicted) key's jkt — producing confusing 401s instead of a clean re-login. Fixed by recording dpopJkt (RFC 7638 thumbprint) on StoredSession at mint time; the renamed loadSessionDpopKeyPair(db, session) now verifies the persisted key's thumbprint against session.dpopJkt and throws DpopKeyUnavailableError on a missing/mismatched key for a current-shape session (dpopJkt present). Both service-worker.ts ensureSession() and auth-flow.ts refreshSession() treat that error like an ordinary refresh failure — clean teardown, not a substitute key. The legacy-migration rotation (no recorded dpopJkt) is unchanged. 2. completeLogin() persisted the newly minted key to the single-record IndexedDB store BEFORE the token exchange succeeded, so a failed/retried login could clobber an existing session's still-valid key. Fixed by splitting mintAndPersistDpopKeyPair into generateDpopKeyPair (unchanged, called early — needed to sign the exchange's own DPoP proof) + persistDpopKeyPair (new — called only after the exchange succeeds, alongside saving the session with its dpopJkt). Tests: dpop-key-store.test.ts rewritten/extended for the new loadSessionDpopKeyPair session-aware contract (legacy-rotate, matching-key, missing-key-throws, mismatched-key-throws) + persistDpopKeyPair's deferred-persist safety (10 tests, was 5). 363 total, gate green: lint, typecheck, test, build. roborev: codex review of b64367d found these 2 Medium findings, no Critical/ High; both addressed above. Model: claude-sonnet-5 Co-Authored-By: Claude Sonnet 5 * fix(auth): roborev round-2 — narrow ensureSession's DPoP-key-load teardown codex's review of d83a142 found: ensureSession() caught EVERY error from loadSessionDpopKeyPair() (including a transient IndexedDB-open failure or an unrelated bug) and destructively tore the session down, silently logging the user out on what might be a momentary fault. Fixed by narrowing the catch to teardown ONLY on DpopKeyUnavailableError (the "this session's key is genuinely gone/mismatched" signal). Any other error now fails that one call soft: cachedKeyPair stays null, the stored session/tokens are left untouched, and the next call retries the DB read cleanly (self-heals once the transient condition clears) — matching every caller's existing "no ctx -> not authenticated" handling rather than adding new throw-handling at each call site. Also fixed a latent test-harness bug this surfaced: service-worker-gate.test.ts's loadWorker() didn't clear messageListeners before vi.resetModules(), so a test calling loadWorker() twice (to model a restart mid-test, needed to actually exercise the DB-read path — a keypair cached in one module instance never re-reads on the same instance) left a stale listener from the FIRST module instance handling the message instead of the second. Fixed by clearing messageListeners at the top of loadWorker(), matching the other two service-worker integration test files. Test added: "a TRANSIENT DPoP-key-store failure fails ONE request soft — no destructive teardown" in service-worker-gate.test.ts (364 tests total, was 363). Gate green: lint, typecheck, test, build. roborev: codex review of d83a142 found this 1 Medium finding, no Critical/ High; addressed above. Model: claude-sonnet-5 Co-Authored-By: Claude Sonnet 5 * feat(access-gate): per-class replica-slice purge on revoke/expiry + requestAccess gesture & rate-limit Access-management Phase-2 residuals (bead suite-tracker-uana, items b + c): (b) Per-class replica-slice purge. Revoking (or expiring) a class grant now synchronously purges exactly that class's replicated bytes + metadata from the extension's shared replica — the resources it resolved to (its pinned targets), scoped to (webId, grantScope) — leaving every other class/origin/user resident. Closes the data-retention gap where a revoked class's bytes lingered until logout. FAIL-CLOSED: the grant's REMOVAL is the authoritative deny and precedes the best-effort byte purge, so a purge failure can never leave access live — it only degrades to "bytes linger until logout" with access already revoked. - new purgeReplicaSlice() in core/replica.ts (targetsCover containment, per-row best-effort so one failure can't abort the slice) - revokeClassGrant() now returns the removed grant; pruneExpiredClassGrants() returns {live, expired}; SW purges each removed/expired grant's slice. (c) requestAccess anti-spam. Two independent, fail-closed defences before the consent window opens or any pod fetch is made: (i) user-gesture requirement — the ISOLATED content script stamps the page-unforgeable navigator.userActivation.isActive; an autonomous (non-gesture) requestAccess loop is rejected. (ii) per-origin fixed-window rate limit (default 3/60s) on the browser-attested origin, with a distinguishable denied-reason. - new pure core/request-access-throttle.ts (decideRequestAccess), wired into the SW handler with best-effort module-level per-origin state. Gate: lint + typecheck + 382 tests (18 new) + build all green.

Extension Architecture (Manifest V3) - -### manifest.json - -- `manifest_version: 3` -- **Background**: Service worker (`background/service-worker.js`, type: module) -- **Popup**: `popup/popup.html` via `action.default_popup` -- **Content scripts** (two entries, both ``, `run_at: document_start`): - - `inject/inject.js` with `world: "MAIN"` — injects `window.solid` - - `content/content-script.js` with `world: "ISOLATED"` — bridges page <-> background -- **Permissions**: `storage`, `activeTab` -- **Host permissions**: `` (needed for authenticated fetches to any pod) -- **Web accessible resources**: `redirect/redirect.html` - -### Message flow - -``` -Page (MAIN world) <--postMessage--> Content Script (ISOLATED) <--chrome.runtime--> Service Worker - inject.ts content-script.ts service-worker.ts -``` - -### Message types - -| Message | Direction | Payload | -|---------|-----------|---------| -| `SOLID_LOGIN` | Popup -> Background | `{ idpUrl }` | -| `SOLID_HANDLE_REDIRECT` | Redirect page -> Background | `{ code, state, iss }` | -| `SOLID_FETCH_REQUEST` | Inject -> Content -> Background | `{ requestId, url, method, headers, body, clientId? }` | -| `SOLID_FETCH_RESPONSE` | Background -> Content -> Inject | `{ requestId, status, statusText, headers, body }` | -| `SOLID_GET_STATE` | Inject -> Content -> Background | (none) | -| `SOLID_STATE_UPDATE` | Content -> Inject | `{ webId }` | -| `SOLID_STATE_CHANGED` | Background -> Content (broadcast) | `{ webId }` | -| `SOLID_SET_CLIENT_ID` | Inject -> Content -> Background | `{ origin, clientId }` | - ---- - -## 3. Injected API (`window.solid`) - -### Core API - -```typescript -interface SolidExtension { - /** The authenticated user's WebID, or null if not logged in */ - readonly webId: string | null; - - /** Perform an authenticated fetch using the extension's Solid session */ - fetch(input: RequestInfo | URL, init?: RequestInit): Promise; - - /** - * Set the client identifier for the current origin. - * This is a dereferenceable URI pointing to a Client ID Document (JSON-LD). - * If not set, the extension uses dynamic client registration. - */ - setClientId(clientId: string): void; - - /** Open the extension login flow (convenience — same as clicking the popup) */ - login(idpUrl: string): Promise; - - /** Log out the current session */ - logout(): Promise; -} - -declare global { - interface Window { - solid: SolidExtension; - } -} -``` - -### Client Identifier Design - -**Problem**: When the extension proxies `solid.fetch` for a website, the Solid server sees the extension as the client — not the website. Websites need a way to declare their own identity. - -**Solution**: Websites call `solid.setClientId()` with a dereferenceable client identifier URI. This URI must resolve to a JSON-LD Client ID Document per the Solid-OIDC spec. - -```javascript -// Website declares its client identity -solid.setClientId("https://myapp.example/.well-known/solid-client"); - -// Now authenticated fetches identify as "myapp.example" to the Solid server -const response = await solid.fetch("https://pod.example/private/data.ttl"); +```text +Page (MAIN world) <-> Content script (ISOLATED) <-> Service worker + inject.ts content-script.ts service-worker.ts + postMessage chrome.runtime ``` -**Behavior**: -- `setClientId(uri)` stores the mapping `origin -> clientId` in the background service worker -- The background validates the URI is dereferenceable (fetches the Client ID Document) and caches the result -- Authenticated fetches from that origin use the declared client_id in DPoP proofs -- If no client ID is set for an origin, the extension falls back to dynamic client registration using the extension itself as the client - -**Post-logout redirect URI limitation**: When using dereferenceable client identifiers, the Client ID Document must include `post_logout_redirect_uris`. For the extension flow, the logout redirect goes to the extension's redirect page, not the website. This means: -- IDP logout redirects to `chrome-extension:///redirect/redirect.html` regardless of the website's client ID -- The website's Client ID Document should include the extension's redirect URI in its `post_logout_redirect_uris` if IDP logout is needed (impractical for general use since the extension ID is dynamic) -- **Pragmatic default**: App-only logout (clear local tokens) rather than IDP logout. IDP logout is only feasible when the website controls its own Client ID Document AND knows the extension ID - -**Open question**: Whether a more ergonomic pattern exists for Solid post-logout flows in the extension context. This is a known limitation of the current Solid-OIDC spec when applied to browser extensions. - ---- - -## 4. Authentication Flow - -Using `@uvdsl/solid-oidc-client-browser/core` with manual adaptations for service worker context: - -1. **User opens popup**, enters IDP URL, clicks Login -2. **Background `auth-flow.ts`** (no `window` available): - - Fetches IDP's `.well-known/openid-configuration` - - Dynamically registers client (redirect_uri = `chrome-extension://${chrome.runtime.id}/redirect/redirect.html`) - - Generates PKCE code_verifier + challenge - - Generates CSRF state token - - Stores auth params in `chrome.storage.local` - - Opens IDP auth URL via `chrome.tabs.create()` -3. **IDP authenticates user**, redirects to `redirect.html?code=...&state=...&iss=...` -4. **redirect.ts** extracts params, sends `SOLID_HANDLE_REDIRECT` to background -5. **Background** exchanges code for tokens (with DPoP proof + PKCE verifier), stores tokens + WebID -6. **Broadcasts** `SOLID_STATE_CHANGED` to all tabs - -### Key technical decisions - -- **DPoP keys**: Generated as **extractable**, exported as JWK to `chrome.storage.local`, re-imported on service worker wake-up (non-extractable keys are lost on suspension) -- **SessionCore usage**: Used for `authFetch()` and `restore()` only; `login()` bypassed in favor of manual auth URL construction -- **Response serialization**: Bodies serialized as text over chrome.runtime messaging (Solid resources are predominantly text/RDF); binary support can be added later via base64 -- **Per-origin client IDs**: Background maintains a `Map` persisted in `chrome.storage.local`. When making an authenticated fetch, the DPoP proof includes the appropriate client_id for the requesting origin - ---- - -## 5. Popup UI (Solid Branding) - -The popup follows Solid brand guidelines (from `.skills/style-guide.md`): +The worker owns authentication, credentials, grants, and replica access. Page code receives +only token-free responses. The ISOLATED bridge stamps the real page origin; the worker +cross-checks it against Chrome's sender before authorizing a request. + +| Path | Implemented responsibility | +|------|----------------------------| +| `src/background/auth-flow.ts` | Solid-OIDC authorization code + PKCE + DPoP through `chrome.identity.launchWebAuthFlow` | +| `src/background/session-store.ts` | Session tokens, profile, recent accounts, client IDs, and grants in `chrome.storage.local` | +| `src/background/core/dpop-key-db.ts` / `dpop-key-store.ts` | Non-extractable private `CryptoKey` persistence in worker-owned IndexedDB | +| `src/background/core/authenticated-fetch.ts` / `origin-policy.ts` | Target-origin credential boundary, header stripping, and DPoP nonce retry | +| `src/background/core/requesting-origin.ts` | Default-deny app-origin verification and same-origin-only foreign fetch policy | +| `src/background/core/class-request.ts` / `request-access-throttle.ts` | Request validation, bounded expiry, user-gesture requirement, and prompt rate limit | +| `src/background/core/class-resolve.ts` | Solid Type Index class-to-target resolution confined to pod origins | +| `src/background/core/class-grant.ts` / `consent.ts` | Pinned-target grant model, mode/expiry checks, and per-class consent decisions | +| `src/background/core/replica*.ts` | Gated CacheStorage bytes, IndexedDB metadata/nonces, conditional revalidation, and write-through | +| `src/background/global-fetch-register.ts` / `src/inject/inject.ts` | Best-effort MAIN-world injection and global fetch routing | +| `src/shared/messages.ts` | Token-free page/bridge/worker message protocol and grant summaries | +| `src/consent/` | Extension-chrome consent window | +| `src/popup/` / `src/sidepanel/` | Shared account surface built with `@jeswr/solid-elements` | +| `e2e/` / `test-site/` | Headed Chromium tests against local Community Solid Server and app sites | + +The MV3 manifest declares `storage`, `identity`, `sidePanel`, `contextMenus`, and `scripting` +permissions and `` host access. Both content worlds are declared in the manifest; +the worker also attempts programmatic MAIN-world registration. Injection has an idempotency +guard. The broad matches enable discovery, while the worker's access checks enforce the +boundary. See [permission rationale](docs/manifest-permissions.md). + +## Implemented `window.solid` API + +The installed object is frozen and its window property is non-configurable. It exposes: + +| Member | Behavior | +|--------|----------| +| `webId` | Current WebID or `null`; the worker withholds identity from ungranted origins | +| `fetch(input, init?)` | Proxied request, gated before replica access or pod egress | +| `setClientId(clientId)` | Store a valid Client Identifier Document URL for the verified origin and grant it legacy whole-pod access | +| `login(webId)` | Start interactive Solid-OIDC login; successful verified page login grants its origin | +| `logout()` | Clear the local session and class grants, and purge replica data | +| `requestAccess({ classes, modes, purpose?, duration? })` | Open per-class consent and return `{ ok, grants }` | +| `listGrants()` | List this origin's live class-grant summaries for the active WebID | +| `revokeGrant(grantId)` | Remove this origin's class grant, purge its replica slice, and return whether removed | +| `resolveClass(classIRI)` | Return `{ shape, targets }` for an allowed class; currently `shape: null` | + +Presence is announced through `solid-extension:ready` and the sticky +`data-solid-extension="1"` marker on ``. Neither carries identity. The global fetch +patch is best-effort transparency: same-origin requests stay native, and cross-origin +HTTP(S) requests consult the worker. If it declines, a passthrough sentinel makes the page +use its captured native fetch with the original arguments. Explicit `solid.fetch` keeps +the worker's denial response. + +### Class-grant flow and enforcement + +1. Sign in through the extension. A click/keypress in an app calls `requestAccess` with + class IRIs, modes, an optional purpose, and a positive ISO-8601 duration. Although the + TypeScript argument permits omitting `duration`, runtime validation requires it and + caps the lifetime at 365 days (year/month components approximate 365/30 days). +2. Before discovery or consent, the worker verifies the origin and requires transient + activation stamped by the ISOLATED bridge. It admits at most three requests per origin + per minute with a best-effort in-memory throttle that resets on worker restart. +3. Resolve the WebID's public/private Type Index registrations (`solid:forClass` with + `solid:instance` / `solid:instanceContainer`) to concrete pod targets. The consent window + shows the origin, classes, modes, purpose, expiry, and targets. Only the extension's own + context may approve; each approved class mints one immutable grant. Deny-all returns + `{ ok: false, grants: [] }`; validation/session/throttle failures reject the promise. +4. Pin the resolved targets in each grant. Class-only origins must satisfy URL membership, + mode, active WebID, and expiry on every request, including a cache hit. Unknown classes + with no targets authorize nothing. Later resolution does not widen an existing grant. +5. `listGrants` filters by verified origin, active WebID, and expiry. `resolveClass` requires + an active session and granted origin; a class-only origin can inspect only a class it + currently holds. Full-grant origins can inspect any class. These APIs expose no tokens. +6. `revokeGrant` removes the grant before best-effort replica-slice purging, so purge failure + cannot preserve authorization. Bytes still covered by another live read grant for the + same origin are retained. Expired grants are pruned and their slices purged on access. + +Implemented modes are `read`, `append`, and `write` (case-insensitive). GET/HEAD require +read, POST requires append, and PUT/PATCH/DELETE require write. Write also covers append, +but does not imply read. Instances match exact resource paths; containers include +descendants. Purpose is an audit/display anchor, not an enforced restriction. + +Legacy whole-pod origin grants retain their broader access and take precedence over class +grants. Revoking a class grant does not remove that separate legacy origin authorization. +This is the existing compatibility behavior, not a migration to the later origin-grant model. + +## Authentication, storage, and replica + +Authentication uses Web Crypto + `jose`, with RDF issuer/profile discovery through N3.js. +The redirect is `chrome.identity.getRedirectURL('callback')`; no extension redirect page is +used. A page-declared Client ID Document is carried into login; otherwise the extension +tries its configured document and falls back to dynamic registration. The shipped hosted +URL and extension ID remain placeholders pending a separate hosting/pinning task. + +Access/refresh tokens stay in `chrome.storage.local`. The private DPoP key is non-extractable +and persists as a structured-cloned `CryptoKey` in IndexedDB across worker suspension. +Refresh reuses that key and persists rotated tokens before use. The audited +`@jeswr/solid-session-restore` decision supports silent restore. + +Replica bytes live in CacheStorage; metadata and DPoP nonces live in IndexedDB. Cache keys +include the active WebID and grant scope. Reads revalidate and never treat cached bytes as +authoritative. Writes are synchronous write-through with conditional headers. Logout +purges before further serving. Page-provided Authorization/DPoP headers are stripped; +credentials attach only to allowed target origins, never the token endpoint or remote +cleartext targets. A foreign target must be the requesting app's own origin to be proxied +without a Solid token. + +## Build and verification + +Use npm with the committed lockfile and Node.js 24: -- **Primary color**: `#7C4DFF` (Solid purple) -- **Logo**: Solid logo displayed at the top of the popup -- **Typography**: Clean, modern sans-serif -- **Layout**: Simple form — IDP URL input + Login button.

Route all three through a single promise-chain serialiser that re-reads inside the critical section. - MEDIUM: resolveClass let any class-only origin enumerate targets for ANY class (private-structure leak). Now a class-only origin may resolve ONLY a class it holds a live grant for; full-grant origins keep open introspection. - Defence in depth: the resolver no longer fetches a type-index ref on a foreign origin (a hostile profile pointing publicTypeIndex at an attacker URL could turn resolution into an SW-side SSRF) — off-pod refs are skipped. - +4 tests: concurrent save+revoke no-resurrect, resolveClass class-scoped allow/deny, full-grant open resolve, SSRF ref-skip.

Replace with a space (the dedupe key joins a fixed kind word + a URL, so a space is unambiguous). No behaviour change.

Resolve against a POD-ONLY origin set (WebID origin ∪ configured pods, issuer excluded) for both ref fetches and resolved targets. - MEDIUM: clearClassGrants (logout) bypassed the class-grant mutex, so it could interleave a concurrent save/prune and leave a grant persisted after logout. Route it through the same serialiser. - +2 tests: resolveClass skips an issuer-hosted type-index ref; concurrent save+clear is serialised (no grant survives logout).

That is DELIBERATE: unconditionally removing it would drop the pod origin in the ubiquitous CSS single-origin topology (WebID + IdP on ONE origin) and break class resolution entirely. The `includeIssuerOrigin: false` rule already achieves the correct policy — the issuer origin is allowed ONLY when it coincides with a genuine pod origin (WebID origin or a user-configured pod), where token-to-that-origin is already normal pod access (and the token endpoint stays protected by isTokenEndpoint); an issuer origin DISTINCT from every pod origin (the profile-controlled vector) is excluded. - Expanded the rationale in podOriginsFor. - +1 test: CSS single-origin (WebID origin === issuer origin) — a same-origin type-index ref IS followed so resolution works (proving no over-exclusion); the distinct-issuer skip is already covered. Model: claude-opus-4-8 Provenance: Opus 4.8 (Fable unavailable) — re-review/upgrade candidate Co-Authored-By: Claude Opus 4.8 * fix(auth): non-extractable DPoP CryptoKey in IndexedDB (design roborev round-1 F3) Migrates DPoP private-key custody off an extractable JWK in chrome.storage.local onto a non-extractable Web Crypto CryptoKey persisted directly in IndexedDB (core/dpop-key-db.ts). Non-extractable CryptoKeys are structured-clone serialisable, so the key survives the MV3 service worker's aggressive kill/restart cycle without ever being exportable — closing the F3 keystore-advantage finding from the design review while keeping the same session-scoped-keypair behaviour (fresh key per login, reused across refreshes, cleared on logout). - core/dpop.ts: generateDpopKeyPair() now generates extractable:false; removed exportDpopKeyPair/importDpopKeyPair/StoredDpopKeyPair (no longer needed — the key is never exported to JWK for storage). - core/dpop-key-db.ts (new): IndexedDB handle for the keypair record (put/get/clear), modelled on replica-db.ts. - core/dpop-key-store.ts (new): mintAndPersistDpopKeyPair (login) and loadOrRotateDpopKeyPair (reload-or-mint) orchestration. - session-store.ts: StoredSession no longer carries dpopKeyPair; loadSession() detects + strips a pre-hardening inline extractable JWK on read (one-time migration) and writes the cleaned record back immediately. A migrated session's refresh token was DPoP-bound to the old key's jkt and will fail its next refresh, which the existing refresh-failure teardown in ensureSession() already turns into a clean re-login — no new complexity needed there. - auth-flow.ts / service-worker.ts: rewired onto DpopKeyDb + loadOrRotateDpopKeyPair; logout now also clears the persisted key. Tests: dpop.test.ts (non-extractability + still-signs-and-verifies), dpop-key-store.test.ts (new — a real DpopKeyDb against a minimal fake IDBFactory proving the structured-clone round trip, not a mocked module), session-store.test.ts (new — the legacy-migration strip + idempotency), and the three service-worker integration suites updated to seed the fake DpopKeyDb instead of embedding dpopKeyPair on StoredSession fixtures. +11 net new test cases (358 total). Gate green: lint, typecheck, test, build. Docs updated in the same change: README.md, docs/manifest-permissions.md, docs/design/shared-replica-architecture.md (marks the residual-LOW key-custody finding as closed, keeps the original text struck through for the record). NO PUSH — landing policy for this (ODI-transferred) repo is under re-confirmation on issue #9; orchestrator decides. Model: claude-sonnet-5 Co-Authored-By: Claude Sonnet 5 * fix(auth): roborev round-1 — dpopJkt-checked key load + defer persist to login success Two Medium findings from codex's review of b64367d, both closed: 1. loadOrRotateDpopKeyPair() silently minted a fresh key whenever IndexedDB was empty, even for a CURRENT-shape session whose access/refresh tokens were bound to a different (lost/evicted) key's jkt — producing confusing 401s instead of a clean re-login. Fixed by recording dpopJkt (RFC 7638 thumbprint) on StoredSession at mint time; the renamed loadSessionDpopKeyPair(db, session) now verifies the persisted key's thumbprint against session.dpopJkt and throws DpopKeyUnavailableError on a missing/mismatched key for a current-shape session (dpopJkt present). Both service-worker.ts ensureSession() and auth-flow.ts refreshSession() treat that error like an ordinary refresh failure — clean teardown, not a substitute key. The legacy-migration rotation (no recorded dpopJkt) is unchanged. 2. completeLogin() persisted the newly minted key to the single-record IndexedDB store BEFORE the token exchange succeeded, so a failed/retried login could clobber an existing session's still-valid key. Fixed by splitting mintAndPersistDpopKeyPair into generateDpopKeyPair (unchanged, called early — needed to sign the exchange's own DPoP proof) + persistDpopKeyPair (new — called only after the exchange succeeds, alongside saving the session with its dpopJkt). Tests: dpop-key-store.test.ts rewritten/extended for the new loadSessionDpopKeyPair session-aware contract (legacy-rotate, matching-key, missing-key-throws, mismatched-key-throws) + persistDpopKeyPair's deferred-persist safety (10 tests, was 5). 363 total, gate green: lint, typecheck, test, build. roborev: codex review of b64367d found these 2 Medium findings, no Critical/ High; both addressed above. Model: claude-sonnet-5 Co-Authored-By: Claude Sonnet 5 * fix(auth): roborev round-2 — narrow ensureSession's DPoP-key-load teardown codex's review of d83a142 found: ensureSession() caught EVERY error from loadSessionDpopKeyPair() (including a transient IndexedDB-open failure or an unrelated bug) and destructively tore the session down, silently logging the user out on what might be a momentary fault. Fixed by narrowing the catch to teardown ONLY on DpopKeyUnavailableError (the "this session's key is genuinely gone/mismatched" signal). Any other error now fails that one call soft: cachedKeyPair stays null, the stored session/tokens are left untouched, and the next call retries the DB read cleanly (self-heals once the transient condition clears) — matching every caller's existing "no ctx -> not authenticated" handling rather than adding new throw-handling at each call site. Also fixed a latent test-harness bug this surfaced: service-worker-gate.test.ts's loadWorker() didn't clear messageListeners before vi.resetModules(), so a test calling loadWorker() twice (to model a restart mid-test, needed to actually exercise the DB-read path — a keypair cached in one module instance never re-reads on the same instance) left a stale listener from the FIRST module instance handling the message instead of the second. Fixed by clearing messageListeners at the top of loadWorker(), matching the other two service-worker integration test files. Test added: "a TRANSIENT DPoP-key-store failure fails ONE request soft — no destructive teardown" in service-worker-gate.test.ts (364 tests total, was 363). Gate green: lint, typecheck, test, build. roborev: codex review of d83a142 found this 1 Medium finding, no Critical/ High; addressed above. Model: claude-sonnet-5 Co-Authored-By: Claude Sonnet 5 * feat(access-gate): per-class replica-slice purge on revoke/expiry + requestAccess gesture & rate-limit Access-management Phase-2 residuals (bead suite-tracker-uana, items b + c): (b) Per-class replica-slice purge. Revoking (or expiring) a class grant now synchronously purges exactly that class's replicated bytes + metadata from the extension's shared replica — the resources it resolved to (its pinned targets), scoped to (webId, grantScope) — leaving every other class/origin/user resident. Closes the data-retention gap where a revoked class's bytes lingered until logout. FAIL-CLOSED: the grant's REMOVAL is the authoritative deny and precedes the best-effort byte purge, so a purge failure can never leave access live — it only degrades to "bytes linger until logout" with access already revoked. - new purgeReplicaSlice() in core/replica.ts (targetsCover containment, per-row best-effort so one failure can't abort the slice) - revokeClassGrant() now returns the removed grant; pruneExpiredClassGrants() returns {live, expired}; SW purges each removed/expired grant's slice. (c) requestAccess anti-spam. Two independent, fail-closed defences before the consent window opens or any pod fetch is made: (i) user-gesture requirement — the ISOLATED content script stamps the page-unforgeable navigator.userActivation.isActive; an autonomous (non-gesture) requestAccess loop is rejected. (ii) per-origin fixed-window rate limit (default 3/60s) on the browser-attested origin, with a distinguishable denied-reason. - new pure core/request-access-throttle.ts (decideRequestAccess), wired into the SW handler with best-effort module-level per-origin state. Gate: lint + typecheck + 382 tests (18 new) + build all green.
