Architecture
Phone integration, widgets, automation, secure space, and plugins only matter if the shell stays coherent under pressure. Valkyrie is built around contracts, control surfaces, guardrails, snapshots, and release discipline so the bigger feature set does not collapse into chaos.
IPC stays grounded in one stable NDJSON control surface instead of fragmenting into a hundred ad-hoc side channels.
{"id":1,"op":"hello"}
{"id":2,"op":"exec","cmd":"secure_space status"}
{"id":3,"op":"subscribe","events":["user"]}
Event rings, tx history, user events, and snapshots make behavior diagnosable and, in the right cases, reproducible.
Unified selectors keep powerful control concise instead of exploding command count and complexity.
Budgets, degrade tiers, watchdogs, quarantine, and host failover mean plugins do not get to take the shell down with them.
Valkyrie can run plugins internally or through an isolated host and still preserve a coherent control model.
Bulk operations and policy transitions are treated as changes worth validating, not random shell side effects.
Desktop-level undo exists because the shell itself remembers important actions.
State, config, and relaunch descriptors can be captured, verified, restored, and carried across systems.
Launch domains stay explicit. Secure work happens in a distinct desktop context instead of pretending workspace alone changes trust boundaries.
This capture shows the whole recovery story: close two windows, move another, distort the working scene, then restore the snapshot and get the desktop back in one action.
Valkyrie ships with release discipline: bundles, manifests, installers, and smoke gates. The architecture matters because the system is meant to be installed, updated, and trusted.
