Controller v0.206.0 shipped the R-241 fixes on 2026-08-07 while the vouched golden still carried 0.205.0, so a machine installed this morning would have received neither - and the next recovery walk would have measured the old behaviour and failed for a reason nothing to do with the walk. Same gap as R-239, one day after R-239 was closed. version 0.206.0 sha256 c85230b42f53baa9c1ee9986ac312c751d6cbc29fbe070d87bb2214429a9108e size 656,750,694 bytes (uncompressed 2,003,138,560) MinAgent 0.127.0 Round-trip verified rather than trusted: the published bytes were fetched back, re-hashed independently (match), zstd-tested, and ./etc/felhom-controller-image was read OUT of the download -> felhom-controller:0.206.0. That last step is the one that matters, because GOLDEN_VERSION is derived from the tag argument and could be right over stale content. All acceptance markers pass; unit Result=success ExecMainStatus=0. Secret hygiene: token file->file, in-VM runner so it never reached a command line (unit-property grep 0), literal-value leak grep on the COMMITTED log 0 - with a positive control proving the grep works before the 0 was believed. Bake VM torn down: CT 9100 purged, secrets shredded, qemu observed gone via ps -eo comm, drill.qcow2 reverted to virgin. THE GATE BUILT EARLIER THIS SESSION NOW PASSES. It was shown CONVICTED against the pre-bake state and is OK now - red to green on the same check, the same command, which is its proof that it measures something real. Note it went green on the BAKE, not the vouch: that is its stated limitation, and the vouch is still pending the operator. NOT VOUCHED - the operator's act. Only one field moves: golden_version 0.205.0 -> 0.206.0 (+ its derived sha). agent_version and min_agent both stay 0.127.0. wrapper_sha256 is unchanged but is CLEARED if omitted from the POST.

Golden 0.206.0 — bake evidence (2026-08-08)
Baked per runbooks/RUNBOOK-manual-build.md §4.0–§4.1, in the drill VM on DooPlex
(/mnt/5_hdd/felhom.eu/drill/drill.qcow2, internal snapshot virgin) — the sanctioned bake exception
in runbooks/target-selection.md. R-239 recurring / R-242.
Baked, published and verified. NOT vouched — the hub's Day-0 artifacts were read but not written. That is deliberate: this part ends at a STOP, and vouching is the operator's act.
WHY THIS BAKE EXISTS AT ALL. Controller v0.206.0 shipped the R-241 fixes on 2026-08-07 while the vouched golden still carried 0.205.0 — so a machine installed on the morning of 2026-08-08 would have received neither, and the next recovery walk would have measured the old behaviour and failed for a reason nothing to do with the walk. This is the same gap as R-239, one day after R-239 was closed, which is what a rule without a mechanism does.
scripts/golden_currency_gate.py(built in this session, and shown FAILING against exactly this state before anything was baked) is the mechanism.

Preconditions, checked rather than assumed
- Clean-tree gate on both source repos:
felhom-controllerHEAD ==origin/main==3d3b4496f377(the image source),felhom-agentHEAD ==origin/main==703db166e762(which ownsbuild-golden.sh). Both trees clean. - Disk headroom

Infra images baked (4, from the controller's own declaration): traefik:v3.6.7,
cloudflare/cloudflared:2026.6.0, gtstef/filebrowser:1.3.3-stable,
gitea.dooplex.hu/admin/felhom-samba:1.1.0.
The published bytes were verified by round trip, not trusted
The bake prints a hash; that is the baker marking its own homework.

var/lib/felhom/docker— the baked images are on the data volume.
Step 4 is the one that matters: GOLDEN_VERSION is derived from the tag argument, so the label
could be right while the content was stale. It is not — the archive says so itself.
Secret hygiene
- Token copied file → file (
scp); never through a shell on either side. - Invocation in an in-VM runner script that reads the token itself, so it never reached a command
line. Verified:
systemctl show golden-bake -p Environment -p ExecStart | grep -c -F <token>→ 0. - Token-leak grep by literal value on the committed log → 0. A broad
[a-f0-9]{40}pattern is wrong here — it false-hits image shas. - Positive control, because an absence proves nothing until the instrument is shown to work: the
token was appended to a throwaway copy → 1 hit; the copy was
shred -u'd; the committed log's 0 is therefore a measurement. Run against the copy in this directory, the one that is committed.
Teardown
pct destroy 9100 --purge (both logical volumes removed, pct list empty) · shred -u of the token,
build-golden.sh, the runner and bake.log after copying the log out · poweroff · qemu observed
gone via ps -eo comm · qemu-img snapshot -a virgin (confirmed: virgin, 0 B VM_SIZE). The drill VM
is back at its baseline and DooPlex is unchanged apart from this evidence directory.
What is NOT done here — the STOP
Vouching. The hub still serves golden 0.205.0 (sha 8f49b2e8…4ee8), agent 0.127.0,
min_agent 0.127.0.
It is a three-field change, and as on 2026-08-07 only one field moves — read from the live
hub_settings, not assumed:
| field | now | after | changes? |
|---|---|---|---|
artifact_golden_version |
0.205.0 |
0.206.0 |
YES |
artifact_golden_sha256 |
8f49b2e8…4ee8 |
c85230b4…108e |
YES (derived from the above) |
artifact_agent_version |
0.127.0 |
0.127.0 |
no — already ≥ the new golden's MinAgent |
artifact_min_agent |
0.127.0 |
0.127.0 |
no — the new golden's MinAgent is also 0.127.0 |
artifact_wrapper_sha256 |
104db0a4…16b3 |
unchanged | no — but it is cleared if omitted from the POST |
Vouching is reversible: re-select the previous values and Save. A bake never deletes an older golden's package (the publish step's pre-delete targets only its own version), so rolling back is a form submission, not a rebuild.
After the vouch, scripts/golden_currency_gate.py should go green — the same check, the same
command. That transition is the gate's proof that it measures something real.
