From 072422d916a477a8d43412dfe8cf3ea2537ae69e Mon Sep 17 00:00:00 2001 From: Andy Dixon Date: Fri, 3 Jul 2026 22:12:31 +0100 Subject: [PATCH] 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 --- CHANGELOG.md | 1 + PLAN.md | 2 +- cmd/noemactl/study.go | 244 +++++++++++ cmd/noemad/main.go | 27 +- docs/snapshots-replay.md | 78 ++++ internal/api/api_test.go | 2 + internal/api/bytes_util.go | 8 + internal/api/server.go | 1 + internal/api/study.go | 429 +++++++++++++++++++ internal/app/app.go | 6 + internal/brain/cycle.go | 19 +- internal/experiments/experiments.go | 387 +++++++++++++++++ internal/experiments/experiments_test.go | 64 +++ internal/replay/driver.go | 159 +++++++ internal/replay/replay.go | 293 +++++++++++++ internal/replay/replay_test.go | 64 +++ internal/replay/replaytest/harness.go | 60 +++ internal/snapshots/archive.go | 507 +++++++++++++++++++++++ internal/snapshots/compare.go | 186 +++++++++ internal/snapshots/snapshots_test.go | 136 ++++++ internal/ui/study.go | 293 +++++++++++++ internal/ui/ui.go | 5 +- migrations/0015_snapshots.down.sql | 3 + migrations/0015_snapshots.up.sql | 49 +++ tests/m1/m1_test.go | 2 + web/static/app.css | 3 + web/templates/layout.html | 3 + web/templates/pages/compare.html | 13 + web/templates/pages/experiment.html | 21 + web/templates/pages/experiments.html | 22 + web/templates/pages/replay.html | 15 + web/templates/pages/replays.html | 20 + web/templates/pages/snapshots.html | 23 + web/templates/partials/mind_tabs.html | 2 +- 34 files changed, 3140 insertions(+), 7 deletions(-) create mode 100644 cmd/noemactl/study.go create mode 100644 docs/snapshots-replay.md create mode 100644 internal/api/bytes_util.go create mode 100644 internal/api/study.go create mode 100644 internal/experiments/experiments.go create mode 100644 internal/experiments/experiments_test.go create mode 100644 internal/replay/driver.go create mode 100644 internal/replay/replay.go create mode 100644 internal/replay/replay_test.go create mode 100644 internal/replay/replaytest/harness.go create mode 100644 internal/snapshots/archive.go create mode 100644 internal/snapshots/compare.go create mode 100644 internal/snapshots/snapshots_test.go create mode 100644 internal/ui/study.go create mode 100644 migrations/0015_snapshots.down.sql create mode 100644 migrations/0015_snapshots.up.sql create mode 100644 web/templates/pages/compare.html create mode 100644 web/templates/pages/experiment.html create mode 100644 web/templates/pages/experiments.html create mode 100644 web/templates/pages/replay.html create mode 100644 web/templates/pages/replays.html create mode 100644 web/templates/pages/snapshots.html diff --git a/CHANGELOG.md b/CHANGELOG.md index 5a8312d..7ea203b 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,6 +5,7 @@ All notable changes to Noema are recorded here.
