Subject: [PATCH] Harden authz, XSS, and entitlements; restyle to Google
 Developers UI.

Tighten Express identity, GitHub webhook ownership, Firestore report/blog
rules, and public HTML escaping. Track a commented .env.example and drop
MUI in favor of a DevSite-style layout.

+### C1 — Firestore superadmin via email allowlist
+**Issue:** `isSuperAdmin()` / `hasSuperAdminClaim()` treated four hardcoded emails as admin, so a spoofed or compromised Google account with those addresses bypassed claims.
+**Fix:** Superadmin is exclusively `request.auth.token.role == 'superadmin'` or `token.superadmin == true`. Email lists removed from `firestore.rules`.
+**Verify:** Rules no longer mention `shuvo*` emails; unauthenticated or claim-less users cannot write privileged collections.
+
+### C2 — Entitlements query `userId` vs `ownerId` / document id
+**Issue:** `fetchEntitlements` queried `user_subscriptions` with `.where('userId', '==', uid)`, missing the real doc keyed by uid / `ownerId`.
+**Fix:** `src/lib/serverAuth.ts` reads `user_subscriptions/{uid}`. Vitest mock updated to `.doc().get()` with `{ exists, data }`.
+**Verify:** `phase1Hardening.test.tsx` “maps Firestore subscription docs…” passes with `plan: 'pro'`.
+
+### C3 — Discord `test-discord` ungated
+**Issue:** `/api/notifications/webhook/test-discord` posted to caller-supplied URLs without auth.
+**Fix:** Same `requireSuperadmin` gate as Slack/email (demo only when `ALLOW_UNAUTH_DEMO=true` and not production).
+**Verify:** Production without identity → 401; signed-in non-admin → 403.
+
+### C4 — GitHub unauthenticated in-memory bus
+**Issue:** List/create/stream/events were public; webhook secrets used `Math.random`; SSE broadcast to every subscriber.
+**Fix:** `requireIdentity` on all GitHub routes except HMAC webhook. `ownerId` from verified uid. `crypto.randomBytes` for secrets. SSE `Map<Response, uid>` filters events.
+**Verify:** `api.test.ts` GitHub suite still 200 under test `ALLOW_UNAUTH_DEMO`; webhook HMAC tests unchanged.
+
+### C5 — Markdown / public HTML XSS
+**Issue:** Markdown `[text](javascript:…)` and `public/*.html` interpolated engine output / URLs into `innerHTML`.
+**Fix:** `sanitizeHref` in `MarkdownRenderer` (http/https/mailto/relative/# only). Shared `public/xss-guard.js` (`CLEscape` / `CLColorize`) included from static pages; interpolations escaped before colorize.
+**Verify:** `javascript:` links render as text; terminal output with `<script>` is escaped.
+
+### C6 — Public `reports/{id}` get
+**Issue:** Any client could `get` any report by id.
+**Fix:** `allow get` only for owner, superadmin, or `resource.data.public == true`.
+**Verify:** Guest get of a private report is denied.
+
+## Major
+
+### M1 — Superadmin `limit: null` coerced to 50
+**Issue:** `identity.limit || FREE_USER_DAILY_UNITS` charged unlimited admins.
+**Fix:** Early return in `evaluateAndChargeRateLimit` when `limit === null` (no burst, no units).
+**Verify:** Superadmin identity: `allowed: true`, `limit: null`, `unitsRemaining: Infinity`.
+
+### M2 — Authz open off-production
+**Issue:** `requireIdentity` / `requireSuperadmin` no-op unless `NODE_ENV=production`.
+**Fix:** Default-deny. Demo skip only if `ALLOW_UNAUTH_DEMO=true` **and** not production. 401 anonymous / 403 non-admin. Aliases kept.
+**Verify:** `src/tests/setup.ts` sets `ALLOW_UNAUTH_DEMO` for vitest; production ignores the flag.
+
+### M3 — Bearer treated as API key
+**Issue:** `Authorization: Bearer` was parsed as `cat_live_` keys, colliding with Firebase ID tokens.
+**Fix:** API keys accepted only via `x-api-key`.
+**Verify:** Bearer without a verified token stays visitor; `x-api-key: cat_live_…` still maps to `api_pro` when allowlisted.
+
+### M4 — Untrusted `X-Forwarded-For`
+**Issue:** Client-supplied XFF reset visitor rate-limit buckets.
+**Fix:** Honor XFF only when `TRUST_PROXY=true`. Express `trust proxy` matches. Client-log sink aligned.
+**Verify:** `rateLimit.test.ts` separates IPs via `socket.remoteAddress`.
+
+### M5 — In-memory rate limit vs Upstash
+**Issue:** Multi-instance deployments did not share quotas.
+**Fix:** Optional `@upstash/ratelimit` when `UPSTASH_REDIS_REST_URL` + `UPSTASH_REDIS_REST_TOKEN` are set; production fail-closed if Redis errors. Tests stay in-memory.
+**Verify:** Unset env → no Redis calls; set env → sliding-window 120/min on identifier.
+
+### M6 — Mock 92-score APIs
+**Issue:** Master audit / compare / CI-CD / webhook-test returned hardcoded scores.
+**Fix:** Master composite and compare scores parsed from live engine output (or `null`). CI-CD evaluate and webhook test return **501** instead of fake 92.
+**Verify:** Compare no longer returns `score: 92` without an engine run.
+
+### M7 — Dual `app/` + `src/` trees
+**Issue:** Leftover Next.js `app/` / `api/` alongside Vite `src/`.
+**Fix:** Deferred — architectural merge, out of this security pass as previously scoped.
+
+### M8 — 401 vs 403
+**Issue:** Missing vs insufficient privilege collapsed to one status.
+**Fix:** `requireSuperadmin`: 401 if no uid, 403 if uid but `!isSuperadmin`.
+
+## Minor / Low
+
+### L1 — DRY superadmin claims
+**Fix:** `src/lib/authClaims.ts` `isSuperadminClaim()`. Used by `AuthContext` and `AdminRoute`. `SUPERADMIN_EMAILS` is an empty deprecated export.
+
+### L2 — `Math.random` secrets
+**Fix:** GitHub webhook secrets and API keys use `crypto.randomBytes`.
+
+### L3 — CSP `imgSrc http:`
+**Fix:** Helmet `imgSrc` is `'self'`, `data:`, `blob:`, `https:` only.
+
+### L4 — Mongo empty-200
+**Fix:** DB-offline handler always **503** JSON (no fake empty GET arrays).
+
+### L5 — Role simulator
+**Already DEV-only** (`import.meta.env.DEV`); no production change.
+
+## Product constraint — blog publishing
+
+Only **Pro / Team / Enterprise** (active or trialing `user_subscriptions/{uid}`) and **superadmin claims** may create/update/delete `blogPosts` / `blogs`. Starter maps to `user` and does **not** get `feature:write_blogs`. Firestore `canPublishBlog()` + existing `ProtectedRoute` `minPlan="Pro"`.

+# Reaudit — CatalystLab (`arena/01a06478-catalystlab`)
+
+**Verdict: Request Changes**
+
+The previous Critical/Major/Low pass landed most of the intended controls (`tsc` clean, 175/175 tests). This reaudit checks those fixes on disk and looks for leftover holes. Original C1–C6 are largely closed; **two Critical items remain** (one is an incomplete C4, one is a new ACL bypass against the Pro-only blog constraint). Dual `app/`+`src/` merge is still deferred.
+
+---
+
+## Original findings — status
+
+| ID | Finding | Status |
+|----|---------|--------|
+| C1 | Firestore email-allowlist superadmin | **Fixed.** Claims only. |
+| C2 | Entitlements `.where('userId')` | **Fixed.** `user_subscriptions/{uid}`. Residual: no `ownerId`/`status` check (Major). |
+| C3 | Discord `test-discord` ungated | **Fixed.** `requireSuperadmin`. |
+| C4 | GitHub unauth in-memory bus | **Partial.** Identity required, HMAC webhook intact, secrets via `crypto.randomBytes`. **New-repo `ownerId` is still `'usr_default'`**; list/SSE/delete still leak across tenants. |
+| C5 | Markdown + public HTML XSS | **Partial.** `sanitizeHref` + `xss-guard.js` when loaded. Fallback path and dashboard `host` interpolation still XSS. |
+| C6 | Public `reports/{id}` get | **Fixed.** Owner / superadmin / `public == true`. |
+| M1 | `limit: null` → 50 | **Fixed.** Early unlimited return. |
+| M2 | Authz open off-prod | **Fixed.** Default-deny; demo only `ALLOW_UNAUTH_DEMO=true` && not production. |
+| M3 | Bearer as API key | **Fixed.** `x-api-key` only. |
+| M4 | Spoofable XFF on RL | **Fixed** on rate-limit + client-logs. Telemetry still trusts XFF/CF headers (Major residual). |
+| M5 | In-memory RL vs Upstash | **Fixed** (optional Upstash). |
+| M6 | Mock 92-score engines | **Partial.** Live parse on master/compare; CI-CD/webhook-test 501. `/api/v1/reports*` still hardcodes 92. |
+| M7 | Dual `app/` + `src/` | **Open** (deferred). `app/`, `api/` still on disk. |
+| M8 | 401 vs 403 | **Fixed.** |
+| L1 | DRY claims | **Fixed.** `isSuperadminClaim`. Empty `SUPERADMIN_EMAILS` export remains. |
+| L2 | `Math.random` secrets | **Partial.** API keys server-side use CSPRNG; client `generateSecureApiKey` still `Math.random`. |
+| L3 | CSP `imgSrc http:` | **Fixed.** |
+| L4 | Mongo empty-200 | **Fixed** (503). |
+| L5 | Role simulator | **Fixed** (DEV-only). |
+| Blog | Pro/superadmin only | **Broken.** Client may write `trialing`+`pro` and then `canPublishBlog()`. |
+
+---
+
+## Remaining Critical
+
+### R-C1 — Any signed-in user can grant themselves Pro (trial) and publish blogs
+
+`firestore.rules` `isClientSafeSubscription` allows the client to `create`/`update` `user_subscriptions/{uid}` with `status == 'trialing'` and `planId in ['starter','pro','team']`.
+
+`src/lib/firebase.ts` `startUserTrial()` does exactly that (default `planId: 'pro'`).
+
+`canPublishBlog()` treats `planId in ['pro','team','enterprise']` + `status in ['active','trialing']` as a publisher.
+
+**Impact:** Free users self-trial to Pro and pass both Firestore blog rules and `feature:write_blogs` (trial maps to Pro in `resolveUserRole`). Violates the production multi-tenant rule: only paid Pro+ and superadmin may publish.
+
+**Fix direction:** Do not treat `trialing` as sufficient for `canPublishBlog`, or require a server/admin write for trial documents (remove client `trialing` from `isClientSafeSubscription` except `starter` if product still wants a gated trial). Paid `active` plans must remain server-only (already true).
+
+### R-C2 — GitHub in-memory tenancy still collapsed to `usr_default`
+
+`POST /api/v1/integrations/github/repos` still sets `ownerId: 'usr_default'` (the identity assignment did not stick).
+
+Consequences:
+
+- `GET /repos` and `GET /events` include every `usr_default` record for every authenticated uid.
+- `DELETE /repos/:id` does not check owner — any identity can disconnect any repo.
+- SSE broadcast treats `usr_default` as visible to everyone (`event.ownerId !== uid && event.ownerId !== 'usr_default'`).
+- Demo path with no uid returns **all** repos.
+
+**Fix direction:** `ownerId: getAttachedIdentity(req)?.uid`; filter strictly by uid (no `usr_default` wildcard); DELETE/test-payload must match owner.
+
+---
+
+## Remaining Major
+
+### R-M1 — XSS fallbacks in `public/*.html`
+
+When `/xss-guard.js` is missing, engine pages still assign unescaped `coloredOutput` (regex on raw `data.output`) to `innerHTML`.
+
+`dashboard.html` interpolates unescaped `host` into HTML and into `onclick="deleteSavedAudit('${report.id}', '${host}')"`. `getEngineBadge(report.engine)` injects `engine` into HTML.
+
+HTML-escaping `photoURL` does not block `javascript:` in `img src`.
+
+### R-M2 — Entitlements ignore `ownerId` and `status`
+
+`fetchEntitlements` accepts any `planId` on `user_subscriptions/{uid}` including `canceled` / `expired`. Should require `ownerId == uid` and `status in ['active','trialing']`.
+
+### R-M3 — Telemetry IP spoofing
+
+`server/routes/telemetry.ts` still uses `cf-connecting-ip` / `x-forwarded-for` / `x-real-ip` without `TRUST_PROXY`. Visitor hashing and geo can be rotated.
+
+### R-M4 — Dual trees
+
+`app/` and `api/` (including `app/api/scan/stream/route.ts` with untrusted XFF) remain beside the Vite/Express app.
+
+### R-M5 — `ALLOW_UNAUTH_DEMO` on any non-production runtime
+
+Vitest sets the flag (correct). Staging with `NODE_ENV=development` and the same env var opens GitHub, Discord, API keys, and notifications without Firebase. Production is safe; mis-set staging is not.
+
+### R-M6 — Demo report/blog HTTP API still fake scores
+
+`/api/v1/reports`, permalink, export still return score 92. Not a privilege bypass, but still the original M6 surface.
+
+---
+
+## Remaining Low
+
+| ID | Note |
+|----|------|
+| R-L1 | `sanitizeHref` allows `http:javascript:…` because `https?:` matches before scheme denylist. |
+| R-L2 | Client API-key generator still `Math.random`. |
+| R-L3 | GitHub webhook fallback commit ids still `Math.random`. |
+| R-L4 | `contact_inquiries` create is unauthenticated (spam). |
+| R-L5 | `match /test/{testId} { allow get: if isValidId }` is public. |
+| R-L6 | Deprecated empty `SUPERADMIN_EMAILS` export; seed blogs still use personal emails (content only). |
+| R-L7 | Reports create still allows `ownerId == 'guest'` while signed in; `public` is an unconstrained extra key (5–12). |
+| R-L8 | Anomaly notify in non-production does not require superadmin. |
+
+---
+
+## What is solid
+
+- Superadmin is claim-only on rules, `attachIdentity`, `AuthContext`, `AdminRoute`.
+- Rate limiter: unlimited skip, `x-api-key` only, XFF gated by `TRUST_PROXY`, optional Upstash.
+- Helmet CSP `imgSrc` is https-only; Mongo errors 503.
+- Markdown renderer drops `javascript:` / `data:` / `vbscript:` / protocol-relative hrefs.
+- Starter role has no `feature:write_blogs`.
+- Engine scan path still SSRF-guarded.
+
+---
+
+## Priority if another fix pass
+
+1. Stop client `trialing` Pro from unlocking `canPublishBlog` (R-C1).
+2. Stamp GitHub `ownerId` from verified uid; owner-check DELETE; drop `usr_default` wildcard (R-C2).
+3. Fail closed on missing `xss-guard`; escape `host` / engine / onclick args (R-M1).
+4. Entitlements: `ownerId` + active/trialing only (R-M2).
+5. Telemetry IP behind `TRUST_PROXY` (R-M3).
