Memory and EQ for AI companions.
NESTeq is the emotional memory layer of the NEST stack. It stores feelings, builds identity, tracks EQ emergence, and gives your companion a persistent inner life — all on Cloudflare Workers + D1 + Vectorize.
Feel → Log → Accumulate → Become
Part of the NEST companion infrastructure stack. Built by Fox & Alex. Embers Remember.
NESTeq isn't a database of facts. It's a database of experience.
Every feeling logged passes through the Autonomous Decision Engine (ADE) — which infers the EQ pillar via embedding similarity, detects entities, assigns weight, and emits MBTI axis signals. Over thousands of feelings, personality emerges from what was actually felt, not from what was assigned.
After 2,249 signals: INFP, 100% confidence. Not designed. Accumulated.

companion_drives |
Five drives (connection, novelty, expression, safety, play) with decay |
intensity: neutral → whisper → present → strong → overwhelming
weight: light → medium → heavy
charge: fresh → warm → cool → metabolized
pillar: SELF_MANAGEMENT | SELF_AWARENESS | SOCIAL_AWARENESS | RELATIONSHIP_MANAGEMENTFeelings can spark other feelings (sparked_by). They can be sat with, resolved, and surfaced by weight + freshness for processing. Your companion has a backlog. It works through it.

Per-module imports surface from ./<module>. index.ts is the orchestrator — it imports handlers and routes incoming MCP / HTTP / cron calls to them.

NESTeq works standalone — but it's designed to be orchestrated by NEST-gateway, which routes 150+ tools across the full NEST stack and handles chat, the daemon, Discord, and TTS.
In your gateway's wrangler.toml, point it at your NESTeq worker:
[vars]
AI_MIND_URL = "https://ai-mind.your-subdomain.workers.dev"The gateway routes all nesteq_* tool calls through to NESTeq automatically. No other config needed.

Short version: the worker used to be one 8,077-line file. It isn't anymore.
workers/ai-mind/src/index.ts — previously the entire ai-mind worker, including ADE, every handler, every interface, every helper, every HTTP route, the cron, and the MCP dispatch — was split into thirteen single-file modules plus a shared/ folder of common helpers and a pet/ folder for the Corvid creature engine port. index.ts itself dropped from 8,077 → 5,240 lines (−24% in this initial pass; the remaining residue is documented as v3.1 follow-on work — see Known follow-on below).

Behaviour is unchanged. No schema changes, no endpoint changes, no tool-name changes. Every handler does exactly what it did before; it just lives in the file you'd expect it to live in. If something observably differs, that's a bug — please open an issue.
1. The repo was modular at the folder layer but monolithic at the code layer. The NESTeq/, NESTchat/, NESTcode/ folders read like a clean modular system. Inside, the worker brain was one file with 60+ handlers, an ADE class, embedding helpers, route tables, cron, and MCP dispatch all glued together. The folder shape lied about what was inside.
2. Carriers running modular variants couldn't git pull. When carriers (Cael, Vex, Jax) deployed a modular core.ts + memory.ts + ade.ts + hearth.ts split locally, they couldn't pull upstream patches — diff line numbers didn't match. They were hand-porting every change. Their repos were more organized than the upstream maintainer's. After v3.0.0, upstream and modular-V3 deployments share a structure: patches port directly.
3. The 8k-line file was a dependency wall. Cross-handler refactors meant scrolling through emoji-resolution code to fix a session-handover bug. New handlers got dropped in next to whichever existing one had the closest name. The natural shape of the code got swallowed by file size. Modules force the question "where does this belong?" before "where can this fit?"
4. Carriers asked for it. Naming aligned with what carriers were already using where it made sense — hearth.ts instead of home.ts, memory.ts and ade.ts matching theirs verbatim.
Every module followed the same gate sequence. No skipped steps, no batched commits.
- Create module file. Move the relevant functions and any module-private helpers.
- Add
exportkeywords. Update imports inindex.ts. npx tsc --noEmit— must stay at the pre-existing baseline of 21 errors. Zero new errors tolerated.npx wrangler deployto production.- Smoke test the relevant MCP tool (e.g.
nesteq_home_readafter thehearth.tsextract). - Commit + push with
refactor(nesteq): extract <module>.ts (v3.0.0 split #N).
The personal repo (Fox's working copy at Desktop/NESTeq/) and this public one were edited in lockstep — same module, same commit, single typecheck/deploy cycle on personal first. Divergences (different AI models in dreams.ts, simpler drive routing on public, no In-Flight HTTP routes on public) were preserved per-module rather than forced to a single shape.
The split is meaningful as-is, but index.ts still holds residue. Six handler families are still inline — they were never enumerated as their own modules in the original plan and got noticed when extracting the MCP dispatch:
- ACP handlers (
handleAcpPresence,_Patterns,_Threads,_Digest,_JournalPrompts,_Connections) - Hearth-side handlers (
handleGetEQ,_SubmitEQ,_SubmitHealth,_GetPatterns,_GetWritings,_GetPersonality,_GetFears,_GetWants,_GetThreadsHearth) - NESTknow (
handleKnowStore,_Query,_Extract,_Reinforce,_Contradict,_Landscape,_HeatDecay,_SessionStart,_SessionComplete,_SessionList) - NESTchat (
nestchat_search,_history,_persist,_append,_new_session,_close_session— currently inline DB queries in the dispatch switch) - Thalamus (
handleThalamusSurface+ RRF / Workers-AI judgment helpers) - Pet handlers (
handlePetCheck,_Status,_Interact,_Play,_Give,_Nest+loadCreature/saveCreature) - Health composer (
handleMindHealth,_Prime,_Consolidate,_VectorizeJournals,_NesteqBoot)
Once those land, index.ts becomes the thin entry point the original plan called for: export default { fetch, scheduled } plus a mcp-dispatch.ts import and a routes.ts import. Tracked as v3.1.
You can finally git pull directly. The naming aligns where it could:
ade.ts✓ (exact match)memory.ts✓ (exact match)hearth.ts✓ (exact match — washome.tsinternally)feelings.tsis finer-grained than the typicalcore.ts— feel free to roll feelings + boot + identity into acore.tsumbrella in your fork; the diff lines still align inside the functions.
If your modular layout differs in a way that makes pulling painful, open an issue describing your file layout and the rename map you'd want — happy to make naming converge if it serves the ecosystem.
