A mind's configuration may override model routing per role (llm_roles);
the router honours it for that mind only and fails closed when the named
model is missing or disabled, so a comparison between providers can never
silently fall back to the default. Experiments may declare variants: each
becomes its own fork of the same snapshot with its own configuration,
personality or routing, receives identical stimuli, and is measured. The
results carry one entry per variant and a deterministic comparison: first
divergent stimulus, belief and attention overlap, mean score difference on
shared propositions, and the ranges of memory counts, goal counts, cost and
capability requests. Single-subject definitions are unchanged.
Snapshots, replays and experiments now record the runtime they ran under:
build (module version, VCS commit, modified tree, commit time, Go version,
platform), schema version, a digest of the non-secret configuration that
ignores secret and credential changes, personality version, policy digest,
model routing including per-mind overrides, prompt versions, deterministic
subsystem versions and timezone. A replay compares its identity with the
snapshot's and is an exact-candidate, a different-build (differences
listed) or incompatible (schema differs; the replay stops before running).
The first non-exact step is analysed into events only in the recording,
events only in the replay, and the components they belong to, labelled as
inferred; live model calls are named as their own source of difference.
Migration 0022 is additive; unrecorded identities are reported as such.
An archive is data about a mind, not a grant of permissions on this
instance. Import now skips the policies table (forks on the same instance
keep theirs), reports the omitted rows in the audit log and the mind's
history, and the snapshot test proves both paths.
- 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
