v1 has no libfftw3. SAE_SCENE_XGB is on by default and pulls the learned
scene-boundary detector into result_sink, whose find_library(FFTW3_LIB
fftw3 REQUIRED) at CMakeLists.txt:377 runs at CONFIGURE time -- so cmake
fails before any target is chosen, and building only `sae_tests` does not
get you past it. The image predates the detector; nothing rebuilt it when
the detector landed, which is precisely the gap DP-007's own register row
records.
-DSAE_SCENE_XGB=OFF would also have made the configure pass. It is the
wrong fix and worth saying why: CI is the only place these tests run, so
a flag that silences a subsystem there silences it everywhere, and the
job would have gone green over a detector nobody was compiling.
The image's self-check gains a line, because an image that ships a
library CMake cannot find the way CMake looks for it is the failure this
block exists to catch. FFTW is checked as a bare .so rather than through
pkg-config, since find_library is what CMakeLists.txt actually calls --
checking fftw3.pc would pass on an image whose libfftw3.so was absent.
Tag bumped v1 -> v2 here, in build_builder_image.sh and in the workflow's
run-time assert, in one commit, as this image's contract requires. v2 is
built and published. Rehearsed in the image before pinning it: configure,
build and 151 tests now run.

DP-007's row says the builder image is "pinned by tag in the Gitea
container registry". The tag was pinned; the image was never pushed.
Every run since the workflow landed died at
"Error response from daemon: manifest unknown" before a single step ran,
so the tier this workflow exists to execute has still never executed.
sae-builder-cpu:v1 is now in the registry, built from ff3b8eb by
scripts/ci/build_builder_image.sh and reporting SAE_BUILDER_VERSION=v1,
which is what the job's own assert-the-image step demands. The
v1-ff3b8eb audit tag went with it.
Behind that, the same absence one layer down: no replay-fixtures package
existed either, so "Verify the fixtures actually arrived" would have
failed next. tests/fixtures/dumps is now published at version ff3b8eb.
Which makes the `latest` here worth removing rather than keeping. Two
reasons, either sufficient. It is the same argument DP-007 already
makes about the image tag -- a dump is an input to the tests, so a
re-upload under a moving `latest` retroactively changes what an earlier
green build proved. And `latest` was the only thing in this job that
wanted a credential: package downloads are anonymous while the repo is
public, and only resolving `latest` needs a token for the list endpoint.
No GITEA_TOKEN secret is configured on this repo, so that step could
never have resolved `latest` even once the image existed. Pinning
deletes the dependency instead of documenting it.
The failure message below it said the step "needs GITEA_TOKEN to resolve
'latest'"; it now says to check the pinned version still exists, which
is the thing that can actually go wrong -- pull_artifacts.sh warns and
continues on a missing version rather than failing, which is why that
verify step is there at all.

docs/requirements.md describes four verification tiers and argues that
T1 (functor unit) and T2 (replay) are "the only tiers that can exist in
CI at all". The traceability gate then reports a CI-scope coverage
fraction over exactly those tiers. Nothing ran them: the only workflow
was the gate itself, which reads source comments, and SAE_BUILD_TESTS
defaults to OFF. "Covered" meant a TRACES tag existed in a file.
That is the same failure the gate's own config warns about one level up
-- counting a test that cannot run -- and the gate cannot see it,
because a tag is all a static reader has.
Runs in the pinned DP-007 CPU builder image, which the image script
already expected this workflow to exist (it names unit-tests.yml and
asserts its tag). Nothing here calls a model: T1 constructs node
functors directly and T2 replays a precomputed dump, so the GPU-free
N100 runner is sufficient by construction rather than by concession.
Two deliberate hard failures. A missing replay fixture fails the job
instead of skipping, because pull_artifacts.sh warns-and-continues and a
T2 test whose input never arrived must not look like a pass. And the
image reporting a tag other than the pinned one fails rather than
building against an unknown toolchain.
It found a real bug on its first run: see the preceding commit. ctest
runs each case in its own process, which turned a 1-in-4 heap corruption
from noise in the aggregate binary into a reproducible failure.
