Direction agreed 2026-07-20: the whole buildsuite pipeline becomes
drivable with only the pinned zig toolchain present. Pre-tclsh phases
(fetch, configure-product generation, compile) move into the zig build
layer with sources in a content-hashed zon-shaped manifest (fossil
sources pin as per-checkin tarballs - '-refresh' becomes 'bump the pin';
fossil-checkout flow retained as the dev alternative); post-tclsh phases
(tcllib/tklib installers, critcl, parsed-totals test gate) stay Tcl
scripts run by the FRESHLY BUILT suite tclsh as build steps. Acceptance
includes a PATH-scrubbed no-tclsh end-to-end demonstration, preservation
of the copy-and-tweak retargeting property, and the recorded rejection of
a bash+powershell polyglot for this layer (polyglot craft remains the
acquisition layer's mechanism - punk-getzig/getpunk first contact).
Cross-references: G-096 direction note marked RESOLVED -> G-102 (its
remaining items close on the current suite.tcl shape regardless); G-099
sequencing now weighs birthing suite_tcl86 onto the chosen driver shape.
