Thread Report: copy the v5 sidecar, so the comment keeps its author counts

[rdryfoos]

One line, plus two tests so it cannot drift back.

What was wrong

Every Thread Report this repository has ever posted carried this directly under the verdict line:

No author counts: the v5 manifest was not found beside the head manifest.

thread-report.py reads authorship from the v5 manifest sitting beside --head. The workflow copied only trace-manifest.json to /tmp/head.json and left trace-manifest.v5beta.json in the app directory, so the authorship sentence ruled in FR-THREAD-20 could never render. Seen on the live comment on #74, 2026-10-09.

The fix is the one line you named:

cp "$APP/trace-manifest.json" /tmp/head.json
cp "$APP/trace-manifest.v5beta.json" /tmp/head.v5beta.json

The adopters' path was never broken, and that is the real finding

extensions/specassay-check/scripts/ci-thread-report.sh, which the bundle ships and the cold path installs, has always copied the sidecar:

v5="${HEAD_REL%.json}.v5beta.json"
[[ -f "$ROOT/$v5" ]] && cp "$ROOT/$v5" "$OUT_DIR/head.v5beta.json"

So no adopter has lost the sentence. Only this repository has, because this workflow predates that script and still does the copying by hand. The duplication is what let the two diverge.

I have not fixed that here. Replacing these steps with a call to the shipped script would delete the divergence rather than patch it, and it is a larger change to the workflow the six specimens' comments depend on, on a day the Sites room is shooting from one of them. It is yours to call, and I would rather raise it than quietly widen a one-line fix.

Tests

In tests/test_samples.py:

• test_the_demo_workflow_copies_the_v5_sidecar_beside_the_head_manifest
• test_the_shipped_ci_copies_the_sidecar_too — the path that was never broken, pinned so it stays that way

Control: with the workflow reverted to main and the test kept, the first one fails. That is the direction that matters; reverting both together proves nothing, which is a mistake I made on the first attempt and then redid properly.

Verified

• suite 224 to 226 passing
• self-gate OK (154 registry IDs)
• doc-versions clean against v0.5.6, 0 warnings

Once this merges I will rebase demo/close-edit-undo onto main and push, so #74's sticky comment re-renders with the authorship sentence, and report the comment URL again.
