 Call `reload()` after changing source data captured by the callback. Reload replays the active transforms without
 changing their order; it does not rerun plugin setup.

LukeParkerDev	10638d1d9f	refactor(app): port the settings store to plain codecs Migration shapes use preserving structs so undeclared stored fields survive, as Effect's onExcessProperty preserve did at every level; explicit-but-invalid legacy values still decode to null rather than absent; persisted() encodes through encodeOrThrow so an invalid in-memory value fails instead of being written.	2026-09-20 16:37:00 +10:00
LukeParkerDev	faa72aea3a	refactor(app): port the server, model, vcs and project stores to plain codecs Migrations keep their behaviour: URL strings and bare HTTP blocks become server objects, canonical-local project buckets move under local, invalid map entries are dropped individually. Migrated definitions now preserve stored fields the migration does not mention, as Effect's onExcessProperty preserve did. The Effect ServerKey is gone; the codec one in runtime/server/key.ts carries the same brand.	2026-09-20 16:36:59 +10:00
LukeParkerDev	211ce5e9f8	refactor(app): port the layout store to plain codecs Same shapes, defaults and migration as before (workspaces flag to map, review panel flag inherited from the file tree, legacy file-tree width), expressed with the codec module instead of Effect Schema.	2026-09-20 16:36:59 +10:00
LukeParkerDev	3858b11bf9	refactor(app): plain codecs for persisted state, starting with tabs Adds an Effect-free codec module for persisted stores with the same recovery semantics as the Persistence helpers, lets persisted() accept either a Schema or a codec while stores migrate, and ports the tab storage schemas as the first store. ServerKey keeps its brand type on both sides so ServerConnection.Key stays one type. Effect leaves the renderer's initial module graph once the remaining stores are ported.	2026-09-20 16:36:58 +10:00
