script-src 'self' alone forbids WebAssembly.compile, and Argon2id
(hash-wasm) compiles a WASM module in the crypto worker -- so the CSP
added in the second-audit hardening broke every password flow on the
deployed site. Add 'wasm-unsafe-eval', which permits WASM compilation
only; JS eval stays banned, and the policy test now pins both facts so
neither can regress silently.

Authored by ChatGPT/Codex in a separate review pass. Reviewed and verified
here before committing rather than taken on trust; findings below.
The substantive change is that the vault sudo key now lives ONLY in the
phrase-gated recovery capsule. A newly written password credential capsule
carries just connection_vault_root, so an ordinary login restores
connectable-tier records without putting personal-tier material behind a
password capsule that is downloadable and therefore offline-guessable forever.
Pre-hardening capsules stay readable, password login does not return their
sudo key, and the next rotation scrubs it. That closes the gate this project
had explicitly set on personal-tier UI.
Legacy vault-enable migration now derives roots deterministically from
phrase-protected material and account_id, so two concurrent attempts cannot
mint divergent roots -- the failure mode the docs previously mitigated with
"enable the vault once, from one device".
Manual (user-chosen) passwords are REMOVED, not merely discouraged, and a new
securityPolicy.test.ts pins that along with several things tests do not
usually reach: the deployment CSP (default-src 'none', frame-ancestors
'none') plus six baseline headers, demo pages free of inline scripts and
remote fonts, and README documenting same-origin self-hosting only rather
than a remote demo embed. llms.txt was updated to match, which I checked
because that test only reads README.
What I verified, since a passing suite proves less than it appears to:
- All 12 fixes from the 2026-07-30 audit survived the rewrite of recover.ts,
changePassword.ts, validation.ts, relay.ts, session.ts and element.ts.
Checked semantically where grep cannot help: changePassword still checks
publish success BEFORE building the tombstone, and vaultSetBinding still
unbinds on origin === null rather than silently rebinding to the worker
global.
- No dependency changes; the package.json diff is scripts only.
- Argon2id and KDF parameters unchanged. The NIP-44 diff ADDS a base64 length
cap before decoding, a memory-DoS guard.
- Validation increased rather than decreased: 44 throws added, 33 removed.
- No disabled or skipped tests, no secrets in the diff.
typecheck clean, 165/165 tests, build green, and the account manager exercised
in a browser: creation correctly refused when relay quorum could not be met,
and on retry failed at the recovery capsule with "No login credential was
published" -- the §18.1 fail-closed ordering doing its job against a flaky
public relay set.

Fixes reported from the live Vercel deployment:
- vercel.json: remove cleanUrls, which was breaking every internal .html
link (ERR_FAILED) since links already use explicit extensions
- Recovery export was silently broken after login or password rotation:
the crypto worker's session state only picked up the recovery capsule
event on register/recover, never on login/changePassword, even though
the decrypted payload always carries it. Surfaced recoveryCapsuleEvent
(and recoveryPublicKey for changePassword) through core's LoginResult /
ChangePasswordResult and wired them into the worker session; covered by
a new account.e2e.test.ts case
- New accounts never got a Nostr profile: publishProfileAndRelayLists is
now called with name: loginName after registration, so the npub's
profile defaults to the chosen login name
- Password manager never recognized the fields (shadow DOM + JS-driven
submission defeat the passive save-prompt heuristics, and the
generated-password screen never put the password in a real input at
all). Fixed with an explicit navigator.credentials.store() call after
every register/login/recover/changePassword; documented as
Chromium-only in docs.html
New: optional manual/custom password (packages/core/src/account/manualPassword.ts),
opt-in per spec §9.3's "future release may permit manual passwords behind
an advanced setting" allowance. Enforces a length floor, a common-password
blocklist, a login-name-substring check, a low-variety-pattern check, and
an entropy floor; the widget shows live non-blocking feedback as the user
types. The generated high-entropy passphrase remains the default,
recommended option.
Integration/interop support:
- window.nostr provider now carries a readonly _bitlogin marker
- window.bitlogin ({ version, isActiveSigner() }) is installed
unconditionally as soon as the script loads, independent of login
state or window.nostr's current occupant. Found and fixed a real bug
along the way: an unconditional assignment is required because browsers
auto-expose any element with a matching id/name as a same-named global,
so <bitlogin-auth id="bitlogin"> silently shadowed window.bitlogin
under a naive `if (!window.bitlogin)` guard. Renamed the demo's own
element id to avoid the same trap and documented the gotcha in docs.html
- docs.html: new section on supporting multiple signing methods
(extensions, NIP-46, BitLogin) alongside each other
- Added packages/demo/public/llms.txt for AI-assisted integration
Deployment: GitHub Pages requires a paid plan for private repos, so its
workflow and the .github directory are removed; README documents
Vercel-only deployment and the direct-from-CDN integration path.
Docs: added docs/future-recovery-options.md, laying out passkey-based
2FA/recovery options (pure 2FA, full independent recovery, and a
constrained middle ground) with pros/cons for future consideration —
not a development plan, nothing here is decided.
59/59 tests pass; core and widget typecheck clean; all fixes verified
live in Chromium via Playwright against an in-memory mock relay.
