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.

G-098 (suite_tcl90 Tk+tklib, tcllib/tcllibc via critcl, test gating)
flipped to achieved 2026-07-20 and archived - all acceptance items
recorded in the goal file across increments 1-7 (Tk 9.0.2 + tklib,
tcllib+tcllibc ~248x hashing speedup, parsed-totals test gate with
dispositioned baseline, full punkshell runtests parity with the Tcl903
baseline including Tk suites unskipped, kit-hosted runs fixed).
New proposed goals mirror the arc for fossil core-8-6-branch (8.6 stays
punkshell's real Tcl 8 target; current punk86-class kits ride prebuilt
third-party tclkits - a provenance gap):
- G-099: suite_tcl86 core - zig-only 8.6 runtime + thread 2.8-branch +
tclvfs + parsed-totals core-test gate with its own dispositioned
baseline. Records expected differences (no zipfs, entry-point/bundled
lib divergences, no tcl::process).
- G-100: Tk 8.6 + tklib + tcllib/tcllibc via critcl on the 8.6 runtime +
punkshell runtests census against a native 8.6 kit baseline.
- G-101: kit container strategy without zipfs (metakit/tclkit lineage vs
cookfs vs zipvfs boot; TEMP_REFERENCE/metakit + KitCreator guidance) -
separated so the well-understood ports stay incrementally landable.
Sequencing recorded in each goal: recommendation is to close G-096's
remainder and run the punk905_beta trial to promotion before activating
the 8.6 arc, so shared suite scaffolding settles before it is forked.
