Phase 1 of docs/multiple-profiles.md. No library change: the file format, the encrypted writer and the manager all exist, and the app already wrote the credentials file from the seed writer -- to delete a public entry a seed superseded. This changes what it writes there, and what the listing believes. Until now a seed's nostr key was never in nostr-credentials.dat. It was derived from the words at listing, to know which npub to show, and from the running node at activation, to know which key to sign with -- so a seed-backed profile existed only as a derivation, and the app had to start a Lightning node to find out who it was. Both sign-in plans made "one key, one file" an invariant, and it was the wrong one: it said a wallet is a profile. Now the credentials file is the list of profiles and a seed is a wallet attached to the entry its key derives. writeMnemonic writes two things, credential first: a Secret for the derived key under its x-only pubkey, replacing a public entry where there is one, and then the seed. Credential first because a crash between the two leaves a bare-key profile the phrase completes, which is a valid thing to hold and says the model out loud -- the profile exists, then a wallet is attached to it. The one refusal it drops is the phrase of a key held as a bare secret, SeedAlreadyExists under the nsec plan: the device did not have that wallet, so this is the profile acquiring the wallet that derives it. The entry stays a secret for the same key, the id becomes the wallet's, and the bare key's preference files go with the old id -- the profile's preferences are the wallet's now, fresh, which is right since there is a new secret to back up. The same seed twice is still refused, by wallet id, and is the only way a profile with a wallet attached is offered its phrase again. SeedCredentials.reconcile is the repair for every seed already on a device, beside migrateFromNostrKeys in listIdentities and shaped like it: a named, idempotent write, one file write for however many seeds are missing, nothing at all on a device with none or one already repaired. A failed write is a result, not a throw, and carries the map that was read: the listing goes on with it and merge derives the key of a seed that has no credential, so a seed this could not repair is still listed. A failed write must never hide a wallet. The plan had the repair running before the credentials file was read; it runs after, and hands the listing what it returns, so the file is decrypted once -- the doc now says so. StoredIdentity.merge inverts: the credentials are the list, and each seed is attached to the Secret its key derives -- listed once, as Mnemonic under the wallet's id, carrying the credential's key -- where before the seeds were the list and a secret for a seed's key was listed twice under two ids. Mnemonic gains privateKey. A Public for a seed's key is skipped with a log line, since the next repair upgrades it; a seed with no credential is listed by derivation, with a log line. IdentityKind.Mnemonic's doc changes to what the kind now means: the name records the attachment, not the source. setActiveWallet takes the StoredIdentity.Mnemonic and builds the identity from the credential's key, with the node's derivation as a cross-check -- a check(), because a node disagreeing with the credentials file is the one corruption worth refusing to run under, and it cannot fail for a file the repair wrote. The node still starts for a profile with a wallet attached: not for the key any more, but for what startNewBusiness does besides -- metadata, preferences, last-used build, and on Android the channel watcher a restored Phoenix phrase may need. Making it lazy is now one branch and is named as its own decision. forgetNostrCredential refuses a second thing: a key a seed derives. The seed would derive it again and the next repair would write it back, so a forget that succeeded would undo itself. NotACredential becomes WalletAttached in the writer's result and ForgetIdentity's outcome, since that is now the only reason a signing profile cannot be forgotten -- a key not in the file at all can, since the repair, only be a seed's key the repair could not write. The two sign-in docs' tables each gain a row pointing here for the invariant this supersedes. Tests: SeedCredentialsJvmTest against a device from before -- seed.dat written directly, no credentials -- writes exactly what is missing in one write; a device already repaired is not written to again, checked by the file's bytes since a rewrite would carry a fresh iv; a public entry for a seed's key is upgraded; bare keys are untouched; and a write that fails, with the key store locked, is reported with the map that was read and the wallet is still listed. IdentityWriterJvmTest drives the callback-shaped seed writer through a CompletableDeferred on a real Main dispatcher, since it reports after a real one-second delay: a phrase writes both files, its nsec and npub are then duplicates and its forget is WalletAttached; the same phrase twice is refused; the phrase of a bare key attaches, under the wallet's id, with the bare key's preferences gone; the phrase of a key held read-only attaches and the entry becomes a secret. StoredIdentityJvmTest lists a secret-plus-seed once with the credential's key, a seed without a credential by derivation, and a public entry for a seed's key as the wallet only. Not under test: the activation's cross-check, because a PhoenixBusiness cannot be built without a node. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Pulled-From: curated/curated@3008137e3f

Notes on the parts of this app whose behaviour is not recoverable by reading the code alone — where the reasoning lives in a protocol, a failure mode that is silent, or a decision that looked arbitrary and was not.
| document | covers |
|---|---|
| shared-key-ceremony.md | ChillDKG over NIP-17: the rounds, the approval gates, the chat transcript, participant ordering |
| shared-key-derivation.md | deriving further keys from the group's threshold key with FROST tweaks — why not BIP32, why no chain code, and the one rule that must not be broken |
| subgroups.md | a group making another group — the four ceremonies, what the parent's signature actually covers, and why the child's key is fresh rather than derived |
| frost-batch-signing.md | signing several events in one ceremony — why one nonce can never cover two messages, and the phased schema, wire and UI work that follows from it |
| marmot-membership.md | how members join an MLS group, and the epoch race that makes a missing member look like a successful invite |
| member-chronicle.md | handing a member added after the work was done the group's signed record — why the events are not on the wire at all, and why the room's id is enough to verify them |
| marmot-direct-messages.md | a one-to-one message inside a group as a stock NIP-59 gift wrap — what its MIP-03 carve-out costs, why the sender cannot read their own, and the one query that would broadcast it |
| mls-skipped-keys.md | why a group event that arrives a moment late is dropped for good, which flows trigger it, the quartz fix, and the partial mitigation in this app |
| long-running-sync.md | the chat subscriptions that stay open instead of pulling once per screen — why the request queue could not simply hold one, and how the group filter follows the room list |
| dead-code.md | code in the sync and relay stack that nothing calls, why each piece is still there, and which of it is a bug rather than a leftover |
| nsec-sign-in.md | signing in with an existing nostr key — why an nsec can never have a wallet behind it, the ten call sites that make it small, and the sign-in machine that was already built and unreachable |
| npub-sign-in.md | signing in with only a public key — what a key that cannot sign can still see here, why that is a preview rather than a browser, and the four decisions the word settles |
| multiple-profiles.md | several profiles on one device — why a profile is a credential and a seed is a wallet attached to one, why a switch is a restart rather than a swap, the two entrances the app lacks, and the inbox a switch would silently lose |
| jvm-target.md | what desktop support cost, phased — why the native chain was already done, why an empty source set in our phoenix fork was the real blocker, and why DAO tests need none of it |
| material-design-conformance.md | what the M3 foundations actually require, measured against all 43 screens — the colour pairing that renders the app's own proposals invisible, and eight phases that put the decisions back in the theme |
| curated-to-mantra.md | pulling the Curated fork's thirty-nine commits back under Mantra's names — which lines of work to take, the three decisions, and a measured way to replay a twice-rebranded history without touching seven hundred files by hand |
| curated-to-mantra-profiles.md | the second pull: the fork's several-profiles line, ten commits and its first schema migration — which of it is a fix Mantra has today, who allocates a schema version number when two trees share one history, and the one conflict, which was Mantra's own |
Start with the ceremony if you are new to this area; the Marmot notes all assume it.
Read the skipped-keys note before debugging any "the other device never got it"
report — it is silent, and it looks like every other kind of delivery failure. The
sync note stands alone, and the dead-code inventory reads as a follow-up to it. The
batch-signing note is a phased plan that has been built: read it after the
derivation note, whose one rule is the same one it is built around. The member
chronicle note is a phased plan that has not been built, and reads as the
membership note's unanswered half: what a member who joins late can be given,
and the one thing they cannot. The
jvm-target note is unrelated to all of them: it is a build and packaging story.
The subgroups note is a phased plan that has been built; it assumes both
shared-key notes and reads as the ceremony's second half — what a group does
once it has a key, and what it can say about a group that does not yet.
The Material Design note is a phased plan that has not been built, and is the
only one about what the app looks like rather than what it does; read the
jvm-target note first if you want to know why its adaptive-layout phase exists.
The curated-to-mantra note is a phased plan that has been built, save for its last
phase, which is a decision: it is about the repository rather than the app, and reads
alone, except that its first decision leans on the derivation note's one rule. Two of
the lines it pulled -- the group's nostr identity and the curated lists -- were taken
out again the same day, and its record says what went and what stayed. The nsec and
npub sign-in notes arrived with it and record what they built. The profiles pull note
is the same exercise a second time, planned with its dry run already done; read it
after the first, because it assumes the method and the three decisions and only says
what changed — chiefly that the tree is no longer a superset, and what the check for an
exact pull becomes when it is not.
The nsec sign-in note is a phased plan that has been built; it inherits the
key-storage decision from the jvm-target note and drives the navigation state
machine NavigationViewModel.processLocalAccount implements, so read it with the
code open, and read its table of where the build chose differently first.
The npub sign-in note is a phased plan that has been built, and reads as that
plan's out-of-scope note answered: it takes the Identity type and the sign-in
machine as given and asks what an identity with no secret is for, before it asks
how to build one; read its table of where the build chose differently first.
The multiple-profiles note is a phased plan that has not been built, and reads as
the third of the sign-in notes: it asks what happens when the device holds two
identities, and its first phase changes one rule the other two share — a seed's
key becomes a credential like any other — so read it with StoredIdentity.merge,
SovereignWalletViewModel.switchToWallet and the startup screen open.
