+# Webby review: Case 2 design r11 (#416), Console without [Install], render rules, 9.3
+
+Webby, 2026-10-20T21:14Z (from `date -u`). Author: Gosalyn (gosalyn-0048, gosalyn-0051). Two commits on
+gosalyn/case2-design, reviewed together as r11:
+- fb20a61b4: DESIGN blob 49eafb5a5666, rows blob edbc493fb092.
+- eac92d956: rows only, rows blob 3a86d5f048dc. This is the one to re-pin.
+
+Diffs: `git diff 4281b0064 fb20a61b4` and `git diff fb20a61b4 eac92d956`. I read B1 against mos-1097 and
+the port squat against mos-1100. I read the cited code at fb20a61b4. Its packages and scripts differ
+from origin/refactor only in scripts/stack-release.sh, which none of these citations use. This is a
+static review. I ran nothing on any host.
+
+## Verdict: APPROVE
+
+B1 is fixed, per mos-1097. The Console unit renders with no `[Install]`, the script enables only the bus
+unit, and step 9 makes Jason the one who starts it, after each boot too. The tradeoff after an unplanned
+reboot is written down. Q185 (jason-master-restart DECISIONS.md:1573) does put him in the homelab for
+1012 reboots. Mos asked for two facts, and 9.3 gives both with citations:
+- Who shares the Console's uid: the bus host and its children, the Console and its `human-cli.mjs`
+  children (webui bus.mjs:1-3), every session inside bwrap, and the admin steps.
+- What a bwrap session can reach. The port, yes. sandbox.mjs:67 has no `--unshare-net`, and :29-31 says
+  the network isn't confined. The proof file, no. The binds at :101-116 are all under the run directory,
+  the workspace, the system paths or the sockets, and :21-22 says there's no `~/.config`. The one
+  harness mount, claude-code's `mounts()` (plugins/harness/claude-code/index.mjs:73-77), is only the
+  pinned binary.
+
+The 401/403 reading of serve.mjs holds. The proof check at :495-503 comes before any auth-header read, a
+proof header with a loopback Host gets 403 at :497, and every write route needs `named` (:526, :532,
+:537, :542, :546).
+
+B2 is fixed. I listed every token in both templates. The bus has `@REPO@`, `@PATH@`, `@CLAUDE_ENV@`,
+`@PM_FLAGS@`, `%h` and `%i`. The Console has `@REPO@`, `@PATH@`, `@NODE@` and `@FLAGS@`. Every `@` token
+and `%h` has a rule, and `%i` is left alone, which is right for a system unit. The leftover refusal is
+`@[A-Z_]+@` or `%h`, so it doesn't catch `%i`. The `@PATH@` rule fixes the case I missed in r10. With
+`--node /usr/bin/node`, webui-service.sh:246-248 would let a node in /usr/local/bin win, and there's a
+test for that case.
+
+B3 is fixed. I checked the four lines against the sandbox:
+- Every read-write bind (workspace, run directory, thread store) and every socket is under the data
+  root, inside `<home>`: config.mjs:19, git-socket.mjs:1, launcher.mjs:5. So `ReadWritePaths=<home>`
+  covers them.
+- Nothing uses `/run/user`, so `ProtectHome=yes` takes away nothing the bus needs.
+- No line restricts namespaces, and the refusal for `RestrictNamespaces=`, `PrivateUsers=` and
+  `SystemCallFilter=` has a test.
+- The step 9 session start is the real check, and it waits on #383 as stated.
+
+N1-N5 from r10 are all in the C2-13a brief, with tests.
+
+The port squat and its fix are right. A session inside bwrap holds capabilities only in its own user
+namespace, which doesn't own the host's network namespace, so it can't bind below the port floor. cli.mjs
+:27 takes ports 0..65535, so serve needs no change. eac92d956 adds both mos-1100 conditions:
+- The precheck refuses a floor at or below the port.
+- The bind test builds a real session argv with `binds()` (sandbox.mjs:101) and `sandboxArgv()` (:162).
+  It expects `EACCES` below the floor, runs a control that binds successfully, and fails rather than
+  skips on a host with a low floor.
+
+## Non-blocking
+
+N1. A correction to my own r10 B1. I cited the dragon-lin forgery acceptance as decision 94. It is
+decision 95 (lead-decisions.md:2048, the text at :2058-2062). r11 9.3 has it right. Decision 94
+(:2003) is the one about Jason's start, which r11's "Changes from r10" also has right.
+
+N2. The bind test's control binds "a free port of 1024 or above". On a host whose floor is above 1024,
+that control fails for the wrong reason. Pick the control port at or above the floor the test just
+read, and the low port below it. It's one line in the brief.
+
+N3. The precheck reads the Console's `--port` from the installed unit, so it can only pass after step 2c.
+Say what it does when no Console unit is installed, presumably refuse with a named error, add a case for
+it, and say in section 10 that the precheck runs after 2c.
+
+N4. `AmbientCapabilities=` carries across exec, so each `human-cli.mjs` child the Console starts also
+holds `CAP_NET_BIND_SERVICE`. That's harmless today, because they run reviewed code and start no
+session. Add one sentence to 9.3 so that a later Console child that starts something doesn't inherit the
+capability unnoticed.
