- Scaffolds a new Rust crate `wasm/sss_recovery` for constant-time Shamir's Secret Sharing over GF(256) with strict Wasm `zeroize`
- Implements purely typed BIP-39 fallback mapped via Deno WebCrypto in `ui/utils/bip39.ts`
- Migrates `server/recovery.ts` logic mapping Device/Voucher + Server shares with Valkey rate-limiting
- Applies mandatory in-memory JS zeroization on all reconstructed buffers

* Added `prf_enabled` and `prf_salt` columns to the `passkeys` table.
* Updated registration API endpoints to request and store the PRF extension capability and generate a secure salt.
* Updated the login API endpoints to map stored PRF salts into the `evalByCredential` array for the WebAuthn challenge.
* Enhanced the client-side WebAuthn SDK (`auth-client.js`) to extract the PRF Base64URL string output, decode it into a `Uint8Array`, and securely derive a 256-bit AES-GCM Key Encryption Key (KEK) via `crypto.subtle.deriveKey` using the `auth-yes:prf:device-share:v1` info string.
* Implemented graceful fallbacks throughout the stack to ensure registration and standard logins proceed if PRF is unsupported.
* Added corresponding unit tests to verify PRF flow and rejection logic.
* Verified visual and functional changes for the optional username input on the login page via Playwright scripts.

- Expanded database schema to include `leaf_hash` in `audit_records` and added `audit_sths` table.
- Implemented `server/audit_merkle.ts` for native WebCrypto RFC 6962 tree computations and inclusion proofs.
- Created asynchronous micro-batcher in `server/audit.ts` to compute STH, sign with SPIFFE key, save to DB, and broadcast via Valkey.
- Refactored `auditLog` to compute leaf hashes synchronously before database inserts.
- Added hermetic unit tests with mock fallback patterns for SPIFFE/FFI in `server/audit_merkle.test.ts`.

Added a new task markdown file `2026-0824.01.jul.feat.webauthn.prf-extension-1200.md` detailing the plan for integrating the WebAuthn PRF extension. It outlines the schema updates, client and server flow implementations, and progressive fallback logic as per Kanban guidelines.

- Add `domain` column to `apps` table.
- Create Valkey caching layers for app resolution by host (`auth:app_by_host:<host>`) and user grants (`auth:grants:<userId>:<appId>`) with PostgreSQL fallback in `server/auth-session.ts`.
- Update `/api/forward-auth` endpoint to resolve `X-Forwarded-Host`, enforce Default-Deny, check RBAC grants, and inject `X-Forwarded-*` scopes.
- Update relevant unit tests to cover missing and invalid scenarios with correct Mock stubs.
