Rebuild + in-situ republish (Approach 6) completed the acceptance. Full `zig
build bootstrap` (pinned 0.16.0) rebuilt the r2 family WITH the G-172 cpu_floor
field now in the embedded [provenance] record (re-stage picked up the build905.zig
floor-field edit; zig-cached C compiles, only the wrap + emit re-ran). family_check
passed for all three members (the new embed_cpu_floor/embed_cpu_model assertions
green). Audit of the rebuilt r2 exes: all three PASS at the baseline floor
(zmm=0 ymm=0 out-of-floor=0).
Published in-situ to punkbin (git 59e7475, pushed origin/master): the three r2
exes + three r2 tomls replaced under existing names/revisions; each toml
[provenance] now carries cpu_floor="baseline" + cpu_model="x86_64"; the [tests]
tclcore line refreshed to the shipped-codegen gate evidence (passed=56041
failed=8, the Aug-06 baseline-rebuild test-gate - was 56039/9); library [tests]
lines unchanged; sha1sums.txt: the 6 r2 lines updated. build_id unchanged per
artifact (the floor field does not enter the identity digest); sha1/size/built
updated.
Every acceptance conjunct verified on this Zen 5 / v4 host: audit zmm=0 on the
republished artifacts; -Dcpu=native still host-tuned (probe: native zmm=123 FAIL
at baseline, PASS at v4 - the floor is a default, not a restriction); the
republished tomls state the floor; punk-runtime surfaces it (info/list/use/fetch);
use/run produce a named 0xC000001D diagnosis on a below-floor recorded cpu_model
(verified by mocked-host tests - not end-to-end demonstrable here: every
published artifact is baseline/v1 which every host meets, and no x86-64 level
exceeds v4); fetch stays ungated.
DOX closeout: detail file -> goals/archive/ (pure rename; Status achieved
2026-08-07; verification evidence + ## Follow-ons recorded). Index entry ->
GOALS-archive.md (removed from GOALS.md). Reference sweep: only the GOALS.md
index entry mentioned G-172 in the live tier (no pending-tense rewrites); design-
decision Notes pointers added to G-105 (inherits the settled default_target
cpu_model shape) and G-130 (consumes the baseline floor decision on its i686
axis). goals_lint clean (80 active, 93 archived); goals_followons parses the 2
open Follow-ons (r1-generation disposition; bin/ punk9* kit rebake).
