Four-increment arc from the 2026-08-08 feasibility investigation:
(1) characterise the untested arms of the current punk::libunknown
::package override (epoch single-arg/indexed forms + error arms, the
entire forget arm, abbreviation acceptance, delegation, re-init guard,
packagepreference interop in both install orders; install-shape pins
marked to flip), (2) migrate that override onto
commandstack::rename_command (one managed stack for both live ::package
overrides - cures the restore_original/wrong-command latent hazard of
the current unmanaged mix), (3) rename_command -punkargs stack-tied doc
blocks (attach at the single rename site, detach at the remove_rename
choke point every removal path funnels through; stackdocs registered
namespace covers renames performed before punk::args loads), (4)
cmdhelp/cmdinfo override-in-place hint (G-166-style second axis, live
get_stack query, no hard dependency) + the flagship {::package epoch}
doc attachment and the commandstack::help how-to.
Investigation evidence embedded in the goal Context: probe-verified
space-form doc define/resolve/undefine/fallback cycle ('i package
epoch' resolves despite the parent's restricted choices - G-051
space-form jump), record-key append contract, undefine_deflist
primitive, no external :📦: callers, the dead
has_package_files declaration, both real-world install orders.
