 - Do not claim end-to-end verification unless theorem coverage actually exists.
 - Keep macOS and Apple Silicon portability. Do not rely on GNU `timeout`, `free`, `taskset`, Docker, Nix, or x86_64 assumptions.
+- The same portability law applies to DOCUMENTATION: commands printed in docs, the cockpit, and the lab manual must run on macOS (BSD userland: `shasum -a 256` not `sha256sum`; no GNU `sed -i` form; prefer portable `python3 -c` one-liners), and every printed command must be executed once before it ships.
+- The cockpit's three laws are load-bearing: renders-evidence-never-asserts (provenance lines, loud FAILED TO VERIFY), never-leave-a-human-in-the-dark (verdict in words, explainers, glossary links), and distinct-roles-with-handoffs (stations never melt). All three are test-enforced; keep them so.
 - Prefer explicit theorem-boundary language over marketing language.
 - Update tests with every behavior change.
 - Do not silently lower risk ratings. A lower score must explain the failed or missing evidence.

+For humans, warden ships the **custody cockpit** — a local, read-only web
+UI organized as a bridge of six role stations (proposer, quorum bench,
+operator, cryptographer, architect, newcomer) over shared evidence
+instruments, with a tmux-style deck showing every station live in
+parallel and a color-guided wizard. It explains itself; no prior warden

 ## macOS / Apple Silicon
 
 The prototype is written for Python 3.11+ and macOS on Apple Silicon. It does not assume GNU coreutils, Linux `free`, Linux `taskset`, GNU `timeout`, Docker, Nix, or x86_64.
 
+One system prerequisite for the wallet features (key generation and
+signing, including `cockpit --demo`): an `openssl` on PATH that supports
+Ed25519. Stock macOS ships LibreSSL as `/usr/bin/openssl`, and older
+LibreSSL versions lack the Ed25519 key commands — self-check with:
+
+```bash
+openssl genpkey -algorithm ed25519 | head -1   # must print a PEM header, not an error
+```
+
+If it errors, `brew install openssl@3` and put it first on PATH (e.g.
+`export PATH="$(brew --prefix openssl@3)/bin:$PATH"`). `git` on PATH is
+needed only for the cockpit's liveness board repo probes.
+
 Lean tooling is detected with `shutil.which("lean")` and `shutil.which("lake")`. If neither is available, `pacta` reports clear diagnostics and still supports offline claim-card generation and static hygiene scans.

 ## Install
 
+Runtime dependencies: **none** — the tool is Python 3.11+ standard
+library. The supported install is an **editable install from a clone**:
+the repo's own files (estate map, lab manual, sample evidence) are part
+of the product and are resolved relative to the checkout.
+
 ```bash
+git clone <this repo> && cd proof-aware-crypto-tooling-agent
 python3 -m venv .venv
 . .venv/bin/activate
 python -m pip install -e ".[dev]"
+pacta wallet cockpit --demo        # smoke-test the human surface
 ```
 
+Zero-install alternative (no venv, no pip, straight from the clone):

+```bash
+python3 scripts/mini_pytest.py                        # dependency-free suite
+PYTHONPATH=src python3 -m pacta wallet cockpit --demo
+```
+
+On a fresh machine with no Lean toolchain and no locally built dogfood
+binary, the suite passes with a handful of clearly labeled skips —
+capability gaps skip, they never fail silently.
+
 PyYAML is optional. Without it, `pacta` can still read the included simple YAML examples and JSON-compatible `.yaml` files.

+## The cockpit surface (attack surface note)
+
+The custody cockpit (`pacta wallet cockpit`) adds a localhost-bound,
+read-only HTTP surface. Its threat posture, stated plainly:
+
+- **No mutating routes exist.** It cannot approve, sign, unlatch, or edit
+  custody state; the test suite asserts byte-level wallet-directory
+  identity across a full request sweep including POST. Custody-mutating
+  acts are only ever printed as CLI commands for the human.
+- **No authentication because there is nothing to operate** — but it binds
+  `127.0.0.1` by default and must not be exposed: it *reads* wallet state,
+  so exposure is an information-disclosure risk (posture, incidents,
+  member fingerprints), not a custody-control risk.
+- **It phones home never by default.** Outbound traffic happens only when
+  the operator explicitly presses «Probe now» (liveness GETs) — page loads
+  perform no network I/O.
+- An attacker who can serve the operator a *fake* cockpit (host compromise,
+  attacker #7) can lie to the human — which is the standing host-compromise
+  boundary above, not a new one; the CLI (`pacta wallet status`,
+  `verify-ledger`) remains the independent second surface.
