+/goal Brainstorm engineering#44 — Solution Design for the two-tier E2E gate machinery (hermetic local harness per merge + same suite on PPE per deploy), handbook §10.3 as primary input (feature P1 under epic #26)
+```
+
+gitea-forge-backups is done. The next open work stream is engineering#44 (E2E gate
+machinery) — a **brainstorming** session to produce its Solution Design.
+
+## Pipeline status (§9)
+
+Gitea is **bootstrap infra outside flotilla** (no PPE/blue-green, spec D-6). The
+§9 pipeline's stand-in is the **scratch-environment gate** (§6.8/§7.3): T-1..T-4
+green on a scratch Gitea + scratch bucket before touching the live forge. This
+session satisfied it — **T-3 green against the scratch bucket** via the deployed
+off-VM checker before relying on the live alert. No UI surface → **E2E browser
+tests N/A**. The marker fix was verified directly on the live forge VM (additive,
+read-only). No flotilla deploy / release tag applies to this bootstrap-infra work.

+## Outcome — gitea-forge-backups SLICE-5 + marker fix COMPLETE

+Both halves of the goal shipped; the gitea-forge-backups capability (SLICE-1..5) is
+now complete (recovery points exist off-host, retention proven, restore proven,

+  **T-3 green** via the deployed off-VM path against the scratch bucket. RB-3/RB-4
