REPORT — R-165: the mp1 merge, built and proven at the bake (2026-08-03)

Overwritten per the standing rule. The prior contents (hub v0.89.0 / R-167, 2026-08-02) have their durable record in hub/CHANGELOG.md and CONTEXT.md S-11/S-12.

Companion: felhom-agent/REPORT.md holds the full session detail — probes, variant evidence, the bake transcript, red-proofs and teardown. This file covers what changed in THIS repo, and the CI verification for all three.

Scope, stated first. The merge is built and green through Phase 5. Phases 6–7 — reinstalling the two demo boxes from the merged golden and proving one end to end — were NOT done, and nothing was wiped. The golden is therefore deliberately unvouched. Remaining work: R-178.

1. What changed in felhom.eu

No hub change; no hub version bump. This repo changed in two places, one of them forced.

scripts/felhom-host-install.sh — forced by a census, not planned. step_grows computed two volume sizes and the install call passed both, so it had to change with the agent or every install would have provisioned a half-sized box. It now computes ONE total, summing the old 80/20 split (226 = the previous 184 + 42), so a standard appliance keeps exactly the 250 G it had — it is simply no longer split by a wall. The size still comes from the physical disk: step_grows already read the thin pool's real free space, and the merge only collapsed its two outputs into one. That is the answer to the task's §8.2 — no row needed filing. --sysdata-grow is deprecated but still honoured, because the agent folds a hand-passed value in rather than dropping it.

Documentation, per the coupling rule — see §3.

2. The bake, as this repo's audit trail records it

documentation/audits/SPIKE-r165-phase0-2026-08-03.md (new) holds P1, P2 and P3 with method, measurement and ruling, including the teardown of every probe artefact at all three layers. The headline measurements:

• P1 PASS — a real pre-merge archive restore-tests clean, mount_parity: ok, 84 s, mountParity untouched.
• P2 — all three variants boot and reboot 3/3; they are separated by scoping, not mechanics. The container's view of /mnt is 8.0K under V-a and V-c, and 17.9M — Docker's entire data-root — under V-b. The operator chose V-c.
• P3 — the four retargeted golden assertions, run against a deliberately wrong shape: 8/8.

3. Documentation coupling

File	Change
documentation/architecture/07-backup-architecture.md	S-1: the contract changed in the same session. New §7.5.1 — the ceiling §7.5 describes no longer exists for a box built from golden ≥ 0.192.0, the bulkhead's replacement (B2) is recorded, and R-175 is FIXED here: the bound is restated as a function of mp1 and scoped to split-layout boxes, naming all three real shapes
documentation/architecture/00-capability-map.md	new row — IMPLEMENTED, not PROVEN-LIVE, with the missing leg named (no box reinstalled, R-178) and the bake cited as the evidence it is
documentation/backlog/OPEN-ITEMS.md	R-165 → shipped-not-yet-proven-live; R-163 CLOSED (its ceiling no longer exists); R-175 CLOSED; R-176 (a) answered by P1, (b) withdrawn — every node is reinstalled, not migrated; R-178 NEW
CONTEXT.md	S-13 (the variant, chosen on measurement; B2's floor; pruning rejected with its reason; no migration exists) and S-14 (prove first, then vouch)
STATUS.md	rewritten section in plain language; the Waiting on you item cleared — both questions are answered; two older entries trimmed so the page did not grow
scripts/CHANGELOG.md	the host-install change, with why it was forced

4. CI — run ids and conclusions

Checked by PULL, matching head_sha to each commit — CI mails only on failure, so an unchecked green is an assumption.

Every commit in this session, across all three repos, is green.

Repo	Commit	Task id	Run #	Conclusion
felhom-controller	4be6467 (v0.192.0, the B2 floor)	39	15	success
felhom-agent	cd6e267 (v0.120.0 + golden 3.0.0)	41	3	success
felhom-agent	4bb84fc (REPORT)	43	4	success
felhom.eu	7406ac7 (phase-0 audit)	40	21	success
felhom.eu	e3525e6 (host-install one grow)	42	22	success
felhom.eu	14d8c00 (docs + registers)	44	23	success

5. --no-verify

Not used anywhere. Every push in this session ran its repo's .githooks/pre-push and passed.

6. What remains — R-178

1. Reinstall demo-hp from golden 0.192.0 through the real installer path; prove claim → deploy an app → back up → restore; show df proving one filesystem and a recovery unit landing on it.
2. Only then reinstall demo-felhom (it carries the PBS-DR/offsite tier, so it is the box whose backup chain a reinstall actually disturbs).
3. Then vouch golden 0.192.0 in the hub, and flip the capability-map row to PROVEN-LIVE.
4. Re-run P1's restore-test against agent v0.120.0 — one command, turns a sound inference into an observation.
