* fix(native-chat): report a failed startup chat reconcile instead of failing app startup At startup the chat host re-checks every saved chat's lease and writes the result to agent-sessions.json. If that write failed (the file lock gave up, the file could not be written, or the file was written by a newer Orca and is read-only here), reconcileRestartLeases rejected, the startup IPC call rejected, and the renderer fell into its degraded "Session restore failed. Changes won't be saved until restart" mode. The reconcile is bookkeeping: a lease left unreconciled grants no writer, and every attach, send and read of a chat reconciles its own lease again. So the startup reconcile now reports its failure through a new optional host dependency, onStartupReconcileFailure, and resolves. The runtime routes it to its onError sink under the scope structured-agent-session-startup-reconcile, or logs it when no sink is installed (the desktop installs none). * fix(native-chat): read restored chats without waiting on lease bookkeeping With native chat on and a chat tab open at quit, the renderer's startup also awaits the chat tab restore (session.tabs.listAll). That restore re-ran the lease reconcile before reading each chat and rethrew its store failure, then recorded each restored tab as visible through a store transaction that throws on a held lock or a read-only store. Either one failed the restore, so startup still fell into "Session restore failed". Reading a chat grants no writer, so the reconcile startup and the restore run is now a reader's: createReaderReconcile never throws, answers whether every lease is settled (recovery is resolved only then; the journal opens either way), and reports each distinct failure once until a reconcile settles. Attach and agent start keep the strict reconcile. The restore's tab republish logs a failed visibility write and still publishes the tab, since a client drops every unpublished chat tab; user-driven publishes still refuse. The host dependency is renamed onLeaseReconcileFailure (scope structured-agent-session-lease-reconcile), since it now also reports for reads. * fix(native-chat): keep every record-store write off the startup chat read path Round-2 review found two more writes on the startup chat restore that could still fail it and put the app into "Session restore failed": republishing a /clear replacement recorded its tab visibility strictly, and resolving a chat's recovery rethrew its store error. The restore also paid one lock wait per tab and per batch of chats while the lock stayed held. The restore now derives tabs from state it already holds: - publishStructuredAgentSessionTab splits into the strict write and projectStructuredAgentSessionTab, which only updates the runtime's snapshot. The restore and /clear replacements only project: a saved tab index already lists every restored chat, and a /clear moves the tab in the same write that commits it. visibilityWriteMayFail is gone. - Chats a legacy profile restores that the index does not list are recorded in one best-effort transaction (store.showSessionTabs), so a failure leaves the index absent to seed again rather than partial. - The read restore's recovery resolution is caught and reported through onLeaseReconcileFailure, deduplicated with the reconcile's reports. - Once lease bookkeeping fails in a restore pass, the rest of that pass skips it, so a held lock costs one wait for the startup reconcile and one for the restore, however many chats are open. User actions (create, reveal, attach, send, the /clear commit) keep their strict writes. * fix(native-chat): start each restore pass from one lease check and stop its bookkeeping at the first failure The restore now runs one reader lease check for the pass and lets each chat re-check and resolve recovery only while the pass is still settled. The first refusal or failed write clears it for the rest of the pass, and every chat is still opened for reading. With another process holding the lock, startup waits on it once in prepare and once in the restore, however many chats are open; a legacy profile waits once more for its tab-index seed. * docs(native-chat): correct restore comments and a test name to match the final design * fix(native-chat): keep a throwing failure sink from failing the startup chat read The lease bookkeeping failure reporter called the host's failure sink directly, so a sink that threw turned a reported, recoverable store failure back into a rejected startup reconcile or read restore. The reporter now catches a sink throw and logs both the original failure and the sink error with console.warn.
