Assembles every constituent repo of a stack into one combined worktree
workspace, laid out at natural relpaths so cross-repo ../foundation/el
imports resolve to the sandbox copy. Sibling of nsbx; pure bash + git
worktree; never touches live :8742/:7770; isolated engram delegated to nsbx.
Add 'nsbx dev <name>' / 'nsbx dev-down <name>' plus a Makefile so a newcomer
goes from clone to coding on an isolated cloned engram in one command. The
worktree is created on a real named branch at a persistent path (never /tmp,
guarded), and the whole worktree is pinned to the clone via an emitted .nsbx-env
so live :8742 / ~/.neuron/engram is unreachable by accident. Optimizes the El
edit->build->run loop so provisional work is built in El against a throwaway
clone instead of prototyped in Python and re-ported. Additive over the proven
primitives; no live cutover.
Generalise the ad-hoc cog-arch (worktree+build+store-clone+C-tests) and
store-fix (secondary soul + launchctl rails cutover) proto-sandboxes into one
reproducible primitive: run experiments and code changes against the REAL
engram runtime on an isolated snapshot of the live mind, with a gated
promote-to-prod path.
Dev environment as a primitive — any team member gets a private, isolated copy
of the mind (separate port/store/process); prod on :8742/:7770 is untouchable
from a sandbox. Wraps the real binary; never reimplements engram logic.
Lifecycle: create/up (consistent store+WAL+config snapshot; place OR build the
runtime from --source/--branch/--binary; boot on an isolated port) · build ·
run · validate (rails as checks: zero-loss under load+reboot, reboot-prove, RSS
bound, retrieval parity, keystone integrity) · promote (gated rails cutover:
snapshot-first, additive binary swap, bootout→settle-poll→bootstrap, verify,
auto-rollback; never pkill/kickstart -k; dry-run unless approved) · destroy.
Dogfooded: reproduced retrieval-parity 25/25 vs baseline and the cog-arch
correspondence-loop known result (Brier 0.028648->0.000586, reboot-proven) and
real-store reboot-prove at 10994-node scale, all inside a sandbox; prod
untouched.
