+These observations apply to exact local commit
+`4f64eab7968182faa16a6ccbc21555de4287c9ec`. The two unrelated, pre-existing
+working-tree changes in the staging E2E task and wrapper were excluded from
+both isolated worktrees.
+
+- `./scripts/quality.sh` passed every configured source, Compose, Helm,
+  release, rollback, migration, security, dependency, static-analysis, and
+  production-image gate. ExUnit reported 367 passing tests; Trivy, Hex, and
+  npm reported no advisory or vulnerability finding at their configured
+  severities. The exact temporary quality worktree, containers, networks,
+  volumes, and image tags were absent afterward.
+- A fresh detached-HEAD browser replay passed all 42 scenarios in the
+  Chromium, Firefox, and WebKit matrix. It exercised registration and account
+  changes, requests and activities, exact/approximate/hidden map discovery,
+  clustering, chat, consent-based tracking, handover, blind reviews,
+  moderation, notifications, restart recovery, accessibility, and responsive
+  overflow. The exact E2E project
+  `who_need_help_e2e_20260724185814-755941` and its isolated database were
+  absent afterward.
+- A fresh isolated 30-second load replay used two web and two worker replicas
+  with 40 public HTTP, 40 WebSocket, and 8 authenticated mutual-aid virtual
+  users. All 34,755 checks and 38,153 HTTP requests passed, including 1,691
+  authenticated chat/tracking iterations and 240 WebSocket heartbeat
+  sessions. Overall HTTP duration averaged 3.095 ms with p95 7.198 ms; the
+  authenticated scenario averaged 7.48 ms with p95 11.21 ms. These are
+  workstation observations, not production limits.
+- PostgreSQL observed no rollback, deadlock, conflict, temporary file, or lock
+  waiter. It peaked at 16 client backends with at least 81 observed connection
+  slots of headroom. Per-web Ecto telemetry recorded 183,553 queries with a
+  272.59 microsecond average total duration, including 246.44 microseconds of
+  execution and 25.20 microseconds of pool queue time. Exact fixture cleanup
+  restored every tracked application-table count.
+- Ten sequential resource samples observed maxima of 345.4 and 359.2 MiB for
+  the web replicas, 225.6 and 222.1 MiB for workers, 120.0 MiB for PostgreSQL,
+  and 310.7 MiB for the isolated proxy. Evidence is retained under
+  `output/performance/goal-final-20260724`; the exact load project
+  `who_need_help_load_20260724190445947286` and its containers, network,
+  database volume, and image tags were absent afterward.
