Changelog

All notable changes to MindOS. Format loosely follows Keep a Changelog; dates are release dates of the source-available publication.

[0.5.0] — 2026-08-24

Publication catches up to the active development line, which had moved four releases ahead. This entry covers v0.3.0 through v0.5.0.

Added

  • Local memory engine — an in-database memories table with a memories_fts FTS5 index (LIKE fallback where FTS5 is absent), engine tag memory-fts-v1. Commands: memory-retain, memory-forget, memory-list, memory-status, memory-import.
  • Git ingest — memory-ingest-git records commits and merged pull requests so cross-session work is visible to later sessions. Idempotent by content address, so re-ingest is a no-op and no cursor file exists to corrupt.
  • Optional embedding layer — embed_worker.py runs sentence-transformers out of process and read-only, adding memory-embed, memory-search, and memory-consolidate-brief. Entirely optional and off the context-pack path.
  • Autopilot v3 continuation — bounded nanny tick, autonomy declarations with model binding and human grant windows, four-state impulse reporting, runner/v1 execution receipts, activity/stall reports, and bounded correction children.
  • Managed intra-bot communication — provider-neutral botmail envelopes, peer allowlists, capability epochs, and idempotent receipts.
  • Hermes session-start context packs — one bounded, digest-sealed pack on the first turn of a session, with provenance and an end-to-end opt-out.
  • CI now byte-compiles every module, runs the six component suites and the context-pack sentinel, and then the full verification suite.

Changed

  • Hindsight is retired. The external semantic-memory dependency is removed from all three surfaces it spanned: the bank.jsonl adapter in autopilot.py, the service probe and hindsight-check in the bridge, and the _brain_hindsight probe plus --hindsight-url / --bank flags in ops.py. brain-inventory now makes no outbound call at all. Retrieval is deterministic, offline, and inside the audit chain; a retain and its audit event commit in one transaction, so an orphaned memory line is impossible by construction. Legacy banks import through memory-import — dry-run by default, and the source file is never mutated.
  • bridge_hindsight_ledger migrates to bridge_export_ledger (bank becomes channel); export is a plain provenance manifest with export-status.
  • Consolidation excludes commit and pull_request memories by default: measured on a live store, 63 of 122 clusters were pure git groups, and merging them would delete the very events a build log reports. --include-git opts back in.
  • Audit append takes BEGIN IMMEDIATE before the tail read, fixing a race where concurrent ticks forked the hash chain.

Security

  • proof/ (live inventories and scratch reports carrying machine-local paths) is removed from the published tree and ignored going forward, alongside installation-reports/.
  • The memory_*.sh cron scripts are not published: they carry machine-specific repository paths. The commands they wrap are documented instead.

[Unreleased]

Added

  • Publication layer: official FSL-1.1-MIT LICENSE (source-available now, MIT after two years per release), CONTRIBUTING.md, SECURITY.md, ARCHITECTURE.md, INSTALL.md, ROADMAP.md, CHANGELOG.md, hardened .gitignore excluding live state, receipts, sessions, Hindsight exports, backups, Keychain values, agent memory contents, and .env files.
  • seed_current_state.py now resolves its home via MINDOS_HOME / HERMES_AUTOPILOT_HOME instead of a hardcoded machine path.

Security

  • Removed tracked installation-report manifests (machine-local inventory artifacts) from the published tree; they remain ignored going forward.

[Initial publication baseline]

Pre-publication history (see git log for the full audited trail):

  • Autopilot control plane v1: tasks, leases with fencing epochs, receipts, audit hash chain, notes, fact graph, handoffs, dispatch planning, metrics.
  • Fleet ops: recover/escalate/doctor/policies with guarded sweeps and FTS drift detection.
  • Migration layer: brain inventory (nine source kinds), dry-run-first import/export, orphan-receipt quarantine, rollback journal, idempotent re-runs.
  • Session retention (sessions-prune) with mandatory age bounds.
  • Full end-to-end verification suite (verify.py) incl. failure/race injection; stability audit documented in STABILITY.md.
