`ludic help` ended with a section titled "contributing to the toolchain itself", listing bootstrap, reseed, docs-gen and release tasks. None of that is available to someone who installed the language — those tasks need the repository — so the shipped tool was advertising work its user cannot do, in a namespace they have to read past to find `new` and `run`. The tasks move to a second program, dev.ludic -> bin/ludic-dev, built from a checkout and excluded from every release artifact. `ludic` keeps the project and package commands and nothing else; `ludic dev …` now explains where the tasks went instead of failing as an unknown command. What this shook out: the two programs share prelude/build/project/pkg, so the helpers each had accreted in whichever file first needed them — cc(), ensure_ludicc, the string functions, title_case, cmd_version — moved to where both can see them. The argument-shift indirection added for the `dev` namespace is gone with the namespace, so commands read argv directly again. `ludic-dev test` asserts the split rather than trusting it: the staged install must build a project, and `ludic dev build` there must fail while naming ludic-dev. install.sh keeps building older tags, whose bootstrap goes through main.ludic.

# detach.ludic — the structural attach/detach pair and its @OnAttach / @OnDetach
|
|
# hooks. `attach P on e` adds a property to a LIVE entity (seeding its fields and
|
|
# firing @OnAttach); `detach P on e` removes it (firing @OnDetach, which still
|
|
# reads the outgoing value before the has-flag clears). This is the structural
|
|
# counterpart to enable/disable — attach/detach create and destroy the property's
|
|
# presence, whereas disable/enable only pause it while keeping the data.
|
|
#
|
|
# Running it prints: 15 1 25 0
|
|
# 15 @OnAttach(Shield): amount seeded to 5, prints 5 + 10
|
|
# 1 one live Shield now matches the query
|
|
# 25 @OnDetach(Shield): reads the outgoing amount 5, prints 5 + 20
|
|
# 0 the Shield is gone — nothing matches
