Phase 15: snapshots, forks, export/import, cognitive replay, experiments
- snapshots: checksummed JSON archive of every mind-scoped state table plus identity/personality/config and the event position; stored, downloadable - fork: restore into a new mind with all ids remapped; event references are kept so history before the fork is shared by reference - export/import: same archive; import is hostile-input validated (size, allow-listed tables, row caps, column names, checksum, forced mind_id) - compare: deterministic counts, belief diffs by proposition, personality and config diffs, event mix - replay: Runtime.Step for synchronous drivers; sandbox fork driven one stimulus at a time under a forbidden capability context; recorded model responses via a replaying router; steps labelled exact / approximate / diverged with recorded-vs-replayed digests - experiments: definition (overrides, stimuli, expectations, seed, duration), background run in a disabled subject mind, stored and exportable results - migration 0015, API, UI (Snapshots and Replay tabs, Experiments section, compare page), noemactl snapshots/compare/replay/experiments, docs

// Package snapshots captures a mind's state as a self-describing archive,

||||
// restores archives into new minds (fork, import) and compares minds.
|

//
|

// An archive is JSON: identity, personality, configuration and the rows of
|
||||
// every mind-scoped state table. Cognitive history (events) is not copied: a
|

// fork shares it by reference through forked_from_snapshot → event_seq. Every
|
||||
// id inside an archive is remapped on restore, so an archive can never
|
||||
// overwrite existing rows, and imported archives are treated as hostile:
|

// bounded size, allow-listed tables, checksum, no secrets.
