Tapping a signing line in the transcript opened whichever session the room was running, resolved by `liveSessionForChatRoom` -- the newest one not yet finished, or failing that the newest one at all. That is a guess, and it was a good one exactly as long as a room had one proposal to guess at. With a chapter and its translation open together, half the lines in the transcript led to the other proposal. The line now says which session it belongs to, so there is nothing left to guess: it carries `frostSigningSessionId` through to the route. A line written before that column opens the room's proposal list instead, which is the honest answer to a line that cannot say what it meant -- every proposal with its own state, and the reader picks -- rather than a guess dressed as an answer. That empties `FrostSigningRoute.sessionId` of its reason to be optional, so it is required, and `liveSessionForChatRoom` goes with it from the interface, the implementation and the no-op. `FrostSigningViewModel` loses its resolution step and the "This group is not signing anything right now" error underneath it -- which was never the right thing to say to somebody who had just tapped a line about a specific session. The transcript keeps doing the one job it is good at: showing a proposal as it happens, and saying whether it is still asking something of you. What it stops doing is standing in for a list of them.

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 |
| 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 |
| 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 |
| 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 |
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 jvm-target note is unrelated to all of them: it is a build and packaging story.
