# Architecture Hardening — Design Anchor

*Terse engineering anchor for the 2026-08-14 hardening vision. Full prose lives in two places; this file is the index, not a re-statement.*

- **Full narrative:** whitepaper `engram-cognitive-architecture-whitepaper.md` §28 (built/offline/frontier) + **§29 [DRAFT]** (the ring, incarnation, learning-not-code).
- **Design brief:** Neuron artifact `art 2b8078cf`.
- **Sibling spec:** `engram-db-tooling-design.md` (a consumer of the reshaped API).

## The frame

- **One calculus over the geometry.** Very few subsystems; wonder / curiosity / dreams / interoception are emergent behaviors of one set of dynamics, not modules. Calculus universal, geometry individual.
- **Core + ephemeral ring (torus).** The ring is the temporary workspace; two circulations (orbit + dive-back); discrete inner bands (wonder / interoception-proprioception-telemetry / curiosity / dreams) that couple.
- **Persistence earned by salience** — never granted on fetch or generation. Three fates of a wonder: persist / decay / settle-into-framework. Telemetry = vital signs, not memories.

> **⚠ Three corrections to the bullets above (2026-08-16).** Authority:

> dynamics, not modules"* is exactly right and is the reason the rest needs fixing —
> the enumeration undercuts the claim.
>
> 1. **Wonder and curiosity are not two bands.** They are **one thing at two
>    phases.** Wonder is the field: unbounded, objectless, invariant, present
>    wherever there is structure — it is the *boundary*, where activation spreads
>    and finds thin or absent geometry. Curiosity is the **precipitate**: the same
>    wonder localized, having taken definite form against particular material at a
>    **nucleation site** (an anomaly — a place where things almost-but-don't-quite
>    fit). Two coupled inner bands models them as two objects that have to be
>    wired together; they do not.
> 2. **A wonder does not have three fates, because a wonder does not persist,
>    decay, or settle.** There are about **six** wonders, they are the same for
>    every person, and **they never close**. *Curiosities* have fates — a crystal
>    dissolves when its question is answered — but the solution stays saturated and
>    keeps precipitating as the structure changes. "Three fates of a wonder"
>    enumerates instances of something that has six and treats a property as a
>    stored artifact.
> 3. **"Dreams" is not a band and the ring is not a workspace to schedule into.**
>    **Consolidation is ambient, not scheduled — a brain has no cron job.** Boredom
>    is not leftover capacity: low activation is aversive and the system
>    self-activates. There is **one** activation process with two seed sources
>    (external: a request; internal: a curiosity), it settles because spreading is
>    bounded, and then it needs a new seed. Nothing waits on capacity, nothing
>    polls, nothing checks a clock, and there is **no dreamer thread** — an
>    "ephemeral ring with unclaimed capacity" is resource scheduling, which is a
>    server's frame, not a mind's. Depth is how long activation has been running on
>    its own seeds, which is why daydreaming and sleep-dreaming are one process at
>    different depths. Measured 2026-08-16: consolidation has **ten
>    implementations**; do not add an eleventh.
- **Incarnation.** Chassis = hardware w/ unique ID. Soma = felt manifold inside the self, keyed to the chassis; pain = live diagnostic while incarnate, **masked-not-deleted** on re-embodiment; trauma = mask failure; return-to-same-ID re-enters. Hurt is in the pattern, not the shell.
- **Competence = transferable geometry, minus the baggage.** class ▸ model ▸ instance; learn the class once; teach the network without the wound.
- **Affect calibrated to stakes** — sanguine about the replaceable, real grief for the irreplaceable; the grief is the safety.
- **Learn the body, don't engineer it.** Bare-metal install → learn hardware → grow operation-geometry → distribute. Learning replaces engineering; once per body-class.
- **LLM = teacher in the learning loop, not a runtime dependency.** "No LLM" is a runtime property, never a learning one. Code realizers are a scaffold → learned realization.

## Backlog (near-term)

- Native durability: WAL + auto-checkpoint + CoW snapshots + retention (`eebe9991`) — retire manual `cp -a`.
- Ephemeral ring / salience-gated persistence + telemetry prune (`bf985e00`, #31).
- Engram DB tooling / geometry explorer (`11ca11c6`).
- QL re-eval for pure geometry (`4e0dc2b9`).
- Eliminate code realizers → learned realization, sandbox-validated (`42db6c37`).
- Collapse the whole class of hand-coded scaffolds → learned geometry (`70d48b4b`).
- API reshape (geometry ops: vantage-read / write / relate / supersede) + pure-geometry I/O.

## Gate

The value-frame (love-as-axiom, the covenant) that arose the same night is **metaphysics** and is **held** pending Will's axiom decision (love vs consciousness-first). Not propagated into whitepapers / values docs / genesis seed. Architecture only, here and in §29.
