hooks/*.sh: take shim from A1 (gate logic lives in _lib/gate.sh)
install.sh: take dispatcher from v0.16 install-split; ported A1's
_lib-copy logic into install/lib-hooks.sh::install_hooks (since
A1 worktree was based on pre-v0.16-split main and couldn't see
the cube structure).
Gate semantics preserved — tokenized KEI_DISABLED_HOOKS, minimal
profile whitelist. Net: −171 (hooks) +104 (_lib new) +15 (lib-hooks)
= −52 LOC across kit.
Constructor Pattern (RULE ZERO). Zero behaviour change, zero flag
drift — all original CLI flags preserved verbatim.
Before: install.sh — 1238 LOC monolith
After: install.sh — 138 LOC dispatcher (sources libs in order)
install/lib-*.sh — 16 cubes, max 183 LOC (lib-menu)
Cubes:
lib-log 21 LOC — logging primitives
lib-backup 63 LOC — rollback trap + BACKUP_PAIRS
lib-profile 115 LOC — MANIFEST.toml profile resolution
lib-args 92 LOC — CLI parsing + --help heredoc
lib-menu 183 LOC — whiptail/dialog/plain-text interactive picker
lib-plan 150 LOC — dry-run --no-execute output
lib-prereqs 91 LOC — hard + soft dependency checks
lib-primitives 131 LOC — primitive copy + MANIFEST drive
lib-rust 114 LOC — cargo workspace build + pre-built support
lib-scaffold 144 LOC — agent/skill/block scaffolding
lib-bridges 31 LOC — project-bridge install
lib-hooks 104 LOC — settings.json jq merge
lib-agents 77 LOC — assembled agent output
lib-skills 23 LOC — skill copy
lib-wizard 20 LOC — sleep-setup wizard invocation
lib-summary 59 LOC — post-install summary
Invariants preserved:
- macOS bash 3.2 compat (no associative arrays, no [[ ]], no ${,,})
- rollback trap wired via setup_backup_trap early in dispatcher
- jq-merge behaviour verbatim in lib-hooks
- scoped Cargo.toml regeneration in lib-rust
Function LOC limits: largest non-heredoc fn 22 LOC (check_soft_prereqs).
Three functions kept >30 LOC because heredoc-dominated (print_help,
print_summary, profile_members); splitting would fragment logical unit.
62 unique function names across cubes, zero duplicates (grep-verified).
bash -n passes on all 17 files. Runtime smoke test deferred to user's
shell (bash-readonly sandbox constraint).
