# 260614 — Squeak & Pharo (image-based Smalltalk) deep dive

Date: 2026-06-14 · Source: **SHARD-WP-0004 T6 (Squeak) + T8 (Pharo)** — combined memo
(justified merge: both are image-based Smalltalks; Pharo is T8's thin "context for T6/T7").

## What this is

A deep dive into the **image-based live-object** environment — Squeak and Pharo (the
substrate Glamorous Toolkit T7 runs on): the **image** as a persistent world of live objects
with **no file/document/app boundary**, the live **inspector**, and Pharo's retreat to
**code-as-text in git** (Tonel/Iceberg).

## Why it matters

- The **purest "live" end** of the batch's spectrum (literate source → notebook snapshot →
  GT/Lepiter live-over-files → **image: everything live**). Names the **live↔snapshot** axis
  the projection model (T16) must carry.
- Hardens the **image-is-not-a-store** boundary (opaque monolithic non-diffable blob; no
  page identity/history/provenance) — generalizes "attach files, not the kernel/image"
  (UC-84, T7) into a named binding boundary (T14).
- Pharo **confirms** the resolution: even image traditions externalize to **git-versionable
  text** (Tonel) to version/collaborate — files-canonical from the Smalltalk side.

## Yield

- **No new UC** (boundary / design prior art; covers T6 and T8). Boundary for UC-34/35/79;
  links UC-83/84 (live→snapshot), UC-54/47/48 (live-object inspection), UC-76/79 (Tonel/git).
