feat(web): keep the wallet-derived encryption key in the vault and unlock once per tab - #391

Conversation
…lock once per tab A wallet login now seals the encryption key its login key stands for (HKDF(loginKey, identityId, "encryption"), the key the wallet registers beside the auth key) into the vault beside the wallet key, at the first login and at a returning one, but only when its public key is the identity's usable ENCRYPTION key. Otherwise nothing is stored and the sign-in says: Your encryption key is held elsewhere. Import it under Settings → Private repos. The unlock was already per tab: one passkey or passphrase gesture opens the encryption key for every repo. UNLOCK_MEMBERS_ONLY and encryptionKeyState give members-only content the same prompt. Session persistence is unchanged: only the spend-capped key survives a reload. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…, and grant forge-community for the star A star is a forge-community write since RC1 and a key scope has a community field: the live test still asked for forge-collab. The returning login on a fresh browser now runs before the grant, since a first approval for another contract registers another encryption key.

…w key, and point to the approval that brings it Review findings on the wallet-derived encryption key: - adoptWalletKeys and addWalletGrant copy the key bytes before anything waits, so the sheet closing mid sign-in (and wiping its bytes) no longer turns the key into zeros. - A wallet's first approval for another contract registers another encryption key, which becomes the identity's usable one: the grant now keeps it, and a login whose key was superseded that way says to approve again rather than to import a key no file holds. - The "not carried over" notice is hidden only when the wallet's key replaced that same key, and the failure notice no longer claims the sign-in finished.

Address this bounded failure before merging if affected vaults must remain accessible without renewal. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Concurrent activity across tabs can silently lose retained encryption keys, and one unreadable retained key can block access even when another valid key is available.

…each wrap with the key it names Each first wallet approval for another Forge contract registers another encryption key, so one vault slot stranded wraps made to the earlier key. The vault now keeps a set of sealed keys per identity, one entry per on-chain key id; a wallet approval, an imported file or a dg key adds to it and never replaces another. A vault written with a single entry reads as a set of one. Readers open a wrap with the held key its recipientKeyId (or senderKeyId) names, trying each held key when it names none; writers still send from the newest. One unlock opens the whole set, with the same protection and zeroing. The session opens wraps to any held key, and a repo wrapped only to keys this browser lacks says so: the "another approval" notice when a wallet approval registered that key, "held elsewhere" otherwise. Settings → Private repos lists every held key and always offers to add another. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…ncryption keys by their stored ids Security review of the encryption key set: - L1: a held key disabled on chain could be the highest held id, and rotation, epoch-0 and private create compared against it, so every private write failed asking to import a key already held. The writer key is now the newest usable ENCRYPTION key among the held ones; the checks accept any held key and name them all. - L2: the dropped-key notice compared against this tab's view of the stored keys, which is empty in a tab-only session, so a re-key could delete stored keys silently. storeInVault now reports the dropped ids from the vault's own entries, and the notice is hidden only when the wallet's keys put every one of them back. - A re-key carries every encryption key that opens and reports the rest, instead of dropping the whole set when one entry does not open.

Treat a per-key blob-open failure as an unreadable wrap.
storedEncryptionKeyIds includes raw entries even when their blobs cannot be opened. A current-maintainer wrap naming such an entry reaches withEncryptionKey, which throws VaultLockedError. loadPrivateSession suppresses only WrapError, so its Promise.all can reject the entire session even when another wrap opens with a different held key. Give this per-entry failure a distinct error and map it to the unreadable-wrap path; keep actual vault-lock errors fatal.
