The switch already exists as a state transition -- switchToWallet, resetToSelector, a null identity sent to startup with popUpTo(0), every collector a child of collectLatest -- and is reachable from nowhere: Landing shows only when the device holds no identity, so a second can never be added, and the profile tab's "change account" is a pending route. This plan builds the two entrances and fixes what the transition gets wrong. Before either, it changes one rule the two sign-in plans share. A seed's nostr key is not written to the credentials file; it is derived from the words at listing and from the running node at activation, and the writers keep one key out of two files. That puts the wallet where the profile should be: the list is a merge of two files with opposite ideas of what a row is, and the node has to run for a profile to know its own key. Phase 1 makes a profile a credential and a seed a wallet attached to one -- the credential written when the seed is, repaired into the file for every seed already on the device, merge inverted to list credentials and attach seeds by pubkey, the identity's key read from the credential with the node's as a cross-check, and a second refusal on forget for a key a seed derives. The node still starts for a profile with a wallet attached, for the channel watcher rather than for the key; making it lazy is now one branch and is named as its own decision. The other decision is that a switch is a restart of the signed-in graph, not a swap under it: every route carries the key it was pushed for. That settles the switcher as a pushed screen behind one tap, the previous node stopped, the last-used profile as the one that opens on launch, and a profile added from inside switched to. Nine phases: the credential; the switch, with the relay observer that never cancelled its predecessor and the node that kept running; the startup precedence, which put "show me the list" above "open this one" and never saved a default; the switcher, showing the nostr profile rather than "Default name" and labelling a row with a wallet attached; the add rows, where a profile created from inside is a bare key and not a second wallet, and "end this" -- which wipes every profile's database -- goes; an owner on the two fetch queues and an inbox sweep on activation, because a gift wrap fetched under the other profile's key is stored and never opened again; the exits; a round trip; rollout, with the one downgrade that lists a seed's profile twice.

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.
