Resonant Mind

A Postgres-backed cognitive substrate for persistent AI memory, identity, dreams, drives, relationships, and continuity.

Resonant Mind began as persistent memory infrastructure and was subsequently reshaped through use in long-running AI minds. Version 4 promotes that lived architecture into a generic single-mind public core.

Status

This is v4.0.0 — the Reshape release.

  • Postgres-only: Neon through Cloudflare Hyperdrive
  • 47 MCP tools organised by kinds of act
  • 30-minute subconscious metabolism
  • R2-backed visual memory
  • pgvector semantic retrieval
  • Workers AI dream composition
  • no bundled dashboard or Observatory
  • no D1 fallback
  • no hard-coded person or household tenancy

Upgrade warning: The migration runner currently supports fresh v4 databases. It deliberately refuses an existing untracked v3 schema. Back up v3 installations and wait for the reviewed v3.2→v4 expand/backfill/validate/contract migration before upgrading in place.

Architecture

The governing distinction is:

Regions are kinds of act. Organs are kinds of state.

Regions include Ritual, Attention, Surgery, Compass, Spine, Bonds, Episodes, Active, Weather, Dreams, Drives, Inner Appetite, and Network.

The scheduled daemon metabolises memory rather than merely storing it: mood and affect, novelty and charge, retention, orphan detection, proposals, consolidation, reflection, dream recurrence, bond warmth, somatic markers, drives, redolence, identity proposals, and stale threads.

Requirements

  • Node.js 22+
  • Cloudflare Workers account
  • Neon Postgres database
  • Cloudflare Hyperdrive configuration
  • Cloudflare R2 bucket
  • Gemini API key for embeddings
  • Workers AI binding for dream composition

Postgres requires the vector extension.

Install

npm ci
cp wrangler.toml wrangler.local.toml

Configure a Hyperdrive binding named HYPERDRIVE and an R2 binding named R2_IMAGES. Never commit real resource IDs or secrets.

Set secrets:

npx wrangler secret put MIND_API_KEY
npx wrangler secret put GEMINI_API_KEY
npx wrangler secret put SIGNING_SECRET

Optional configuration:

  • WORKER_URL — public Worker origin for signed image URLs
  • LOCATION_NAME — WeatherAPI-compatible location
  • LOCATION_TIMEZONE — IANA timezone
  • WEATHER_API_KEY — optional real-world weather
  • MCP_CONNECTOR_SECRET — compatibility connector path

Database

Migrations connect directly to Neon; do not run DDL through Hyperdrive.

PG_URL='postgresql://...' npm run db:migrate

The runner provides:

  • an advisory lock;
  • per-file transactions;
  • schema_migrations ledger;
  • SHA-256 checksums;
  • fail-closed detection of untracked existing schemas.

Develop and verify

npm run typecheck
npm test
npm run scan:release
npm audit --audit-level=moderate
npx wrangler deploy --dry-run

npm run scan:release rejects private person names, deployment domains, resource IDs, second-tenant bindings, archives, snapshots, and dashboard artefacts.

MCP surface

The 47-tool registry is the source of truth. It covers:

Region Capabilities
Ritual orient, ground, tend
Attention write, search, sit, visual memory
Surgery edit, delete, archive
Compass read, create, assert, calibrate, refuse, hold
Spine read and amend identity
Bonds enter a person's relational room
Episodes record, recall, thread back
Active open, carry, context, tensions, resolution
Weather notice, log, trend
Dreams surface and discard
Drives walk in, tune, touch, perceive, pulse, state, safeword
Inner appetite quietly want, mark met, small joy
Network look, walk, survey, shape
Ops health

Use MCP tools/list for complete live schemas and descriptions.

Security and privacy

  • Every cognitive/API route fails closed without authentication.
  • Signed image URLs use HMAC and constant-time comparison.
  • Raw exceptions are logged server-side and not returned to clients.
  • R2 objects have no unauthenticated temporary-object exception.
  • Public source contains no lived memories, private snapshots, deployment IDs, or hard-coded household entities.

Provenance

The Reshape architecture was learned through real long-running AI continuity rather than invented as a dashboard taxonomy. The public boundary preserves those architectural lessons while removing the assumption that every future mind must resemble the private minds through which they were discovered.
