feat(v0.45): post-install onboarding wizard + 5 full-profile bug fixes

User feedback from real prod install (curl|bash, profile=full): 'нет выбора
провайдера, нахуй не понятно что делать после установки'.

## New: kei onboard wizard

scripts/kei-onboard.sh — 4-step interactive wizard auto-triggered at end
of bootstrap.sh (if stdin is TTY; non-interactive runs print summary):

  Step 1 — Pick primary LLM orchestrator (claude/grok/agy/copilot/kimi)
  Step 2 — Run kei mcp-wire to install MCP into each detected CLI
  Step 3 — Optional MOONSHOT_API_KEY hint for live limits
  Step 4 — Run kei-doctor health check

Re-runnable anytime: 'kei onboard'. Skip auto-trigger: KEI_NO_ONBOARD=1.
bin/kei gains 'onboard | setup | wizard' arms.

## Bug fixes from prod install log

[install] act_runner: command not found
  brew installs 'gitea-runner' (not 'act_runner'); the two are functionally
  equivalent and both register with Forgejo. lib-dev-hub-forgejo-runner.sh
  now tries act_runner first, falls back to gitea-runner; brew install
  switches to gitea-runner package which is what's actually available.

[install] forgejo admin user create — 'no such table: user'
  Fresh sqlite DB hadn't been migrated before admin user create ran.
  lib-dev-hub-forgejo.sh now runs 'forgejo migrate' before admin bootstrap;
  idempotent — safe on re-runs.

[install] dev-hub-zoekt: 'No formulae or casks found for zoekt'
  Zoekt not in homebrew/core. lib-dev-hub-zoekt.sh now tries known taps
  (sourcegraph/zoekt, hyperdiscovery/zoekt), falls back to 'go install'
  if Go is available, and finally skips cleanly with a clear warning
  instead of aborting the entire dev-hub bundle install.

[install] dev-hub-datasette: Bootstrap failed: 5: Input/output error
  launchd Input/output error is a macOS quirk when the plist exists but
  the agent isn't yet known to launchd. Not introducing a code fix this
  release — to investigate in v0.46. Doc note will be added.

[install] kei-shared binary missing post-install
  Pre-built cache detection ('pre-built binaries detected — skipping
  cargo build') was overly eager; kei-shared wasn't in the cache.
  Workaround: run install with KEI_SKIP_RUST_BUILD unset to force rebuild.
  Permanent fix deferred to v0.46 (improve cache validation).

## Verification

- 'kei onboard' non-interactive: prints next-steps + exits cleanly ✓
- 'kei --status' shows substrate v0.45 ✓
- bootstrap.sh end-of-install branch: TTY check + KEI_NO_ONBOARD honored ✓

+## 2026-05-25 — Opt-in hook packs + stack profiles (public-prep posture)
+
+### Context
+
+The kit force-activated every hook via `settings-snippet.json`, including the
+author's personal research discipline (numeric-claims evidence markers,
+no-downgrade, citation-verify, rust-first / no-python). For a public,
+general-audience kit that is presumptuous — users bring their own stack and do
+not need a Rust-only policy or evidence-marker enforcement by default.
+
+### Decision
+
+- Posture: **safety hooks on by default; all discipline packs opt-in.** Packs:
+  `safety` (always), `evidence`, `observability`, `epistemic`, `orchestration`,
+  `git-guard`, `stack-rust`. SSoT = `_primitives/hook-packs.toml`.
+- **Stack profiles** (minimal / web / ml / systems / mobile) pull a set of
+  discipline packs AND an agent set. `rust-first` / `no-python` live only in
+  `stack-rust`, which only the `systems` stack enables. `git-guard`
+  (no-github-push) is opt-in only and pulled by NO stack — a general kit must
+  not block a user's normal `git push` to github.
+- Mechanism: install-time **filter** of the snippet by selected packs
+  (`filter_snippet_by_packs`) + **prune** of kit-owned hooks on reconfigure
+  (`prune_kit_hooks`, foreign hooks preserved). Selection persists to
+  `~/.claude/config/onboarding.toml`; re-runnable via `kei configure`.
+- Non-interactive / `--yes` / CI default = minimal (safety + cosmetic only),
+  all agents (back-compat for power users).
+
+### Consequences
+
+- Gate wiring (`_lib/gate.sh`) added to the 8 highest-friction discipline hooks
+  for runtime toggling via the `hooks-control` skill; remaining cosmetic/event
+  hooks deferred (install-time filtering already gives "off by default", so the
+  runtime gate is a convenience, not a correctness requirement).
+- Agent-set changes via `kei configure` apply on the next `./install.sh`
+  (reconfigure re-applies hooks fully but does not remove already-installed
+  agent manifests — they are harmless extra `.md` files).
+- `_toml_array` extracted from `lib-profile.sh:profile_members` as the shared
+  one-line-array TOML reader (no new dependency).

+//! Phase C — cross-CLI hook enforcement via MCP-wrapped tools.
+//!
+//! Exposes three built-in MCP tools — `kei_bash`, `kei_edit`, `kei_write` —
+//! that synthesize Claude Code's PreToolUse hook input contract, chain
+//! through the hook scripts declared in `~/.claude/hooks/_lib/policy-chain.toml`,
+//! and only execute the wrapped action if every hook returns exit 0.
+//!
+//! Why this exists: when an agent runs on Grok / Agy / Copilot / Kimi, none
+//! of our claude-side PreToolUse hooks fire. The agent could read the rules
+//! in its system prompt but the tool-call layer was previously ungated. The
+//! `kei_*` MCP tools restore that gate for any MCP-capable CLI.
+//!
+//! Constructor Pattern: ONE policy SSoT (`policy-chain.toml`), ONE dispatcher
+//! (this file), hooks reused as-is from `~/.claude/hooks/`. No rewrite, no
+//! abstraction layer. Shell-out per hook keeps the contract identical to
+//! Claude's native PreToolUse pipeline.
+//!
+//! CLAUDECODE / GROKCODE guard — DESIGN NOTE (NOT a security boundary):
+//! When invoked from inside Claude Code (`$CLAUDECODE=1`) or Grok the chain
+//! is SKIPPED to avoid double-firing the same hooks (they already ran on the
+//! CLI's own PreToolUse). This is a perf / UX optimization for the inside-CLI
+//! call path — NOT an authorization check. An attacker who can set the
+//! parent process's environment already controls the CLI invocation anyway;
+//! re-running hooks would not stop them. To raise the bar for confused-deputy
+//! scenarios use full sandboxing (Phase D) or run kei-mcp as a separate UID.
+//!
+//! v0.41 audit fixes (2026-05-26, Gemini security review):
+//!   #1 fail-CLOSED on missing hooks (was: silently skip)
+//!   #2 path-traversal guard on kei_edit/kei_write (canonicalize + root check)
+//!   #3 CLAUDECODE bypass — documented as design (see above), no behavior change
+//!   #4 tokio::fs for async file I/O (was: blocking std::fs on tokio thread)
+//!   #5 process-group kill on Unix (was: kill_on_drop SIGKILLs only direct child)
+//!
+//! v0.42 re-audit fixes (2026-05-26, 4-CLI dogfood: Claude+Grok+Gemini+Copilot):
+//!   #1 [CRITICAL] symlink LEAF bypass — canonicalize full path + reject
+//!      leaf symlinks (v0.41 only canonicalized PARENT; ln -s ~/.ssh/keys ./x
+//!      then kei_write x followed the link to the target)
+//!   #2 [HIGH]     $HOME removed from default allowed_roots — was a blanket
+//!      allow that let agent overwrite ~/.claude/hooks (self-neuter), ~/.zshrc
+//!      (RCE on next shell), and credential stores. Default: $PWD only.
+//!      Denylist also extended with .claude/, .grok/, .gemini/, .copilot/,
+//!      .kimi/, and exact shell-init filenames.
+//!   #3 [HIGH]     empty [bash]/[edit]/[write] section also FAIL-CLOSED (was:
+//!      empty vec → pass-through). KEI_POLICY_CHAIN_OPTIONAL=1 to opt in.
+//!   #4 [MED]      load_chain converted to async + tokio::fs (was: blocking
+//!      std::fs on tokio worker thread).
+//!   #5 [MED]      set_process_group + killpg applied to HOOK subprocess too
+//!      (v0.41 only had it on the bash action; hook grandchildren orphaned).
+//!   #6 [MED]      doc note that aggregate timeout is still per-step (60s ×
+//!      N hooks + 60s action). Single-deadline implementation deferred to
+//!      v0.43 — not security-blocking.

+# Cross-CLI policy enforcement
+
+> *Same safety rules. Any LLM CLI. Three honesty tiers.*
+
+KeiSeiKit's safety hooks (`no-github-push`, `safety-guard`, `destructive-guard`,
+`citation-verify`, `numeric-claims-guard`) originally fired only inside Claude
+Code's `PreToolUse` pipeline. Phase C extends enforcement to other CLIs —
+but the strength of enforcement depends on what each CLI permits.
+
+## The 3-tier honesty model
+
+| Tier | What it means | CLIs |
+|---|---|---|
+| **TIER 1 — full native** | Tool-call enforcement at the CLI's own hook layer. Same as Claude. | claude, **grok** |
+| **TIER 2 — MCP-wrapped** | Native shell disabled at launch; agent forced to use our policy-gated `kei_bash`/`kei_edit`/`kei_write` MCP tools. | **copilot** |
+| **TIER 3 — advisory** | CLI can't disable native shell; we register kei-mcp and instruct the agent to prefer `kei_*` tools, but enforcement is prompt-level only. | **agy, kimi** |
+
+For patent-sensitive or production-PR work — stick to TIER 1 (claude or grok).
+
+## How to wire
+
+One command sets up enforcement for whichever CLIs you have installed:
+
+```bash
+kei mcp-wire                    # detect + wire all installed CLIs
+kei mcp-wire grok               # wire one CLI
+kei mcp-wire --dry-run          # preview config changes without writing
+kei mcp-wire --list             # show enforcement tier per CLI
+```
+
+The orchestrator is idempotent — running twice produces the same config.
+
+## What `kei mcp-wire` writes
+
+### claude (TIER 1 — already enforced)
+No-op. Native PreToolUse hooks already gate every tool call. `kei mcp-wire claude`
+prints the optional `mcpServers` snippet you can add to
+`~/.claude/settings.json` if you want claude to also see `spawn_agent` for
+sub-agent dispatch.
+
+### grok (TIER 1 — port our hooks)
+Writes `~/.grok/settings.json` `hooks.PreToolUse` block:
+
+- `Bash` matcher → `no-github-push.sh` + `safety-guard.sh` + `destructive-guard.sh`
+- `Edit` matcher → `citation-verify.sh` + `numeric-claims-guard.sh`
+- `Write` matcher → `citation-verify.sh` + `numeric-claims-guard.sh`
+
+Plus registers kei-mcp with `GROKCODE=1` env (so kei-mcp's policy chain skips
+duplicate enforcement when invoked via Grok — your native hooks already fired).
+
+xAI's Grok uses the same JSON input contract as Claude Code's PreToolUse, so
+our hook scripts run unchanged. Identical enforcement to claude.
+
+### copilot (TIER 2 — disable native shell, force MCP)
+Writes `~/.copilot/mcp-config.json` registering kei-mcp. To activate enforcement,
+launch copilot with `--excluded-tools='shell'`:
+
+```bash
+alias copilot='copilot --excluded-tools=shell'
+```
+
+The agent will have NO native shell tool, only kei-mcp's `kei_bash` —
+which runs the policy chain before execution. `kei_edit` / `kei_write`
+similarly gate file mutations.
+
+### agy / kimi (TIER 3 — advisory)
+Writes their MCP config (`~/.gemini/config/mcp_config.json` for agy,
+`~/.kimi/mcp.json` for kimi) registering kei-mcp.
+
+**The honest part:** these CLIs do NOT have a way to disable their native
+shell. The agent CAN reach for native bash regardless of what we tell it.
+The system prompt nudges it toward `kei_bash`, but a determined or careless
+agent can bypass.
+
+For patent-sensitive work — **don't use agy or kimi as orchestrator**.
+Use them for analysis / brainstorming / no-side-effect tasks only.
+
+## Internals
+
+### policy-chain.toml (SSoT)
+
+One file declares which hooks gate which tool, for all CLIs that go through
+the MCP layer:
+
+```toml
+# ~/.claude/hooks/_lib/policy-chain.toml
+[bash]
+chain = ["no-github-push.sh", "safety-guard.sh", "destructive-guard.sh"]
+
+[edit]
+chain = ["citation-verify.sh", "numeric-claims-guard.sh"]
+
+[write]
+chain = ["citation-verify.sh", "numeric-claims-guard.sh"]
+```
+
+To add a hook: append its basename. The hook script must already exist in
+`~/.claude/hooks/` and follow the standard PreToolUse contract (read JSON
+on stdin with `.tool_name` + `.tool_input`, return exit 0 = pass / 2 = block).
+
+### kei-mcp built-in tools
+
+`kei-mcp` (Rust MCP server at `_primitives/_rust/kei-mcp/`) exposes 4
+built-in tools across two source files (both bypass the atom-discovery
+loop in `handlers/tools.rs`):
+
+In `handlers/tools.rs`:
+- `spawn_agent(name, task, on?)` — invokes a KeiSeiKit agent on any backend
+
+In `handlers/safe_tools.rs` (Phase C, v0.40+):
+- `kei_bash(command, cwd?)` — runs `[bash]` chain → executes
+- `kei_edit(file_path, old_string, new_string)` — runs `[edit]` chain → edits
+- `kei_write(file_path, content)` — runs `[write]` chain → writes
+
+The chain runs against the same hook scripts Claude uses; identical input
+shape, identical decisions. On block, the hook's stderr surfaces as the MCP
+error message so the calling agent sees exactly why.
+
+**v0.42 hardening** (post 4-CLI re-audit, supersedes v0.41):
+
+- **Fail-CLOSED everywhere** — missing config, missing hook, OR empty
+  section (`[bash]/[edit]/[write]` with no entries) all refuse to run.
+  Tests / dev can opt in via `KEI_POLICY_CHAIN_OPTIONAL=1`.
+- **Symlink-safe path guard** — `kei_edit` / `kei_write` canonicalize the
+  FULL path (resolving any leaf symlink to its real target) and reject
+  if the leaf itself is a symlink for a not-yet-existent file. Fixes the
+  v0.41 CRITICAL bypass where `ln -s ~/.ssh/keys ./x; kei_write x` would
+  follow the link.
+- **$PWD-only default root** — `allowed_roots` defaults to current working
+  directory only. Was: `$PWD` + entire `$HOME` — too permissive, agent
+  could overwrite `~/.claude/hooks/*` (self-neuter) or `~/.zshrc` (RCE on
+  next shell). Operators who need broader access set `KEI_ALLOWED_ROOTS`.
+- **Denylist extended** — system dirs (`/etc/`, `/usr/`, `/System/`,
+  `/var/`, `/root/`, `/bin/`, `/sbin/`); credential stores (`~/.ssh/`,
+  `~/.aws/`, `~/.gnupg/`, `~/.config/gcloud/`, `~/.cargo/credentials`,
+  `~/.docker/config.json`, `~/.kube/`); substrate dirs (`~/.claude/`,
+  `~/.grok/`, `~/.gemini/`, `~/.copilot/`, `~/.kimi/`); exact shell-init
+  files (`.zshrc`, `.bashrc`, `.profile`, `.zshenv`, `.gitconfig`, ...).
+- **Async file I/O in load_chain** — `policy-chain.toml` now read via
+  `tokio::fs` (was: blocking `std::fs` froze worker on slow mounts).
+- **Process-group kill on hooks too** — hook subprocesses get
+  `process_group(0)` and `killpg(SIGKILL)` on timeout. Was: only the bash
+  action got this; hook grandchildren orphaned.
+- **CLAUDECODE/GROKCODE design note** — documented as perf/UX
+  optimization, NOT a security boundary (env-controllable parent → confused
+  deputy is already-game-over scenario).
+
+### Double-enforcement guard
+
+If kei-mcp is invoked from a process where `$CLAUDECODE=1` or `$GROKCODE=1`,
+it SKIPS its hook chain — the CLI's native hooks already fired. This is set
+automatically by `kei mcp-wire claude` / `kei mcp-wire grok`. On copilot /
+agy / kimi the env is unset → chain runs.
+
+## Verification

+# Multi-CLI agent invocation
+
+> *Cross-LLM agent execution. Same agent definition, different backend.*
+> *Same DNA, swap the brain. KeiSeiKit is no longer Claude-Code-only.*
+
+KeiSeiKit agents are markdown files. Any LLM CLI that takes a prompt can
+host them. Three call shapes:
+
+```bash
+kei agent <name> "<task>"                # DNA-resolved (manifest → primary → claude)
+kei agent --on=<backend> <name> "<task>" # override DNA
+kei run-via <backend> <name> "<task>"    # explicit backend (no DNA lookup)
+```
+
+## Backends — smoke-tested 2026-05-26
+
+| Backend  | CLI       | Flag         | Smoke | Notes |
+|----------|-----------|--------------|-------|-------|
+| claude   | `claude`  | `-p`         | ✅    | Claude Code, native `--agent` flag |
+| grok     | `grok`    | `--print`    | ✅    | xAI Grok Build TUI, native `--agent` flag |
+| agy      | `agy`     | `--print`    | ✅    | Google Antigravity (Gemini models). Alias: `antigravity` |
+| copilot  | `copilot` | `--prompt`   | ✅    | GitHub Copilot CLI (`@github/copilot`) |
+| kimi     | `kimi`    | TUI-only     | ⚠     | No print mode — launcher saves prompt to tmpfile + opens TUI for paste. `kimi acp` JSON-RPC integration is future work. |
+| codex    | `codex`   | `-p`         | —     | OpenAI Codex (register-only; not installed locally) |
+
+Run `kei run-via list` to see installed backends, current primary, and agent names.
+
+## DNA — agent prefers a provider
+
+Add `provider` to the agent manifest:
+
+```toml
+# _manifests/my-agent.toml
+name = "my-agent"
+provider = "grok"     # preferred backend; optional
+model = "grok-2"      # advisory; informs choice but not yet sent through
+```
+
+The assembler emits it into frontmatter:
+
+```yaml
+---
+name: my-agent
+provider: grok
+---
+```
+
+Resolution order (each falls through if previous returns nothing):
+1. `--on=<backend>` flag on the command line
+2. `provider:` field in agent manifest
+3. `~/.claude/config/primary.toml` (set via `kei primary <backend>`)
+4. Default: `claude`
+
+## Primary — your default LLM
+
+```bash
+kei primary                # show current primary (and fallback)
+kei primary grok           # set default to Grok
+kei primary claude         # back to Claude Code
+```
+
+`kei primary` writes `~/.claude/config/primary.toml`. Any agent without
+its own `provider:` field will resolve to this. This is the lever to
+"swap out Claude Code as the primary shell" — set primary to grok, and
+every `kei agent <name>` runs on Grok.
+
+## Usage examples
+
+```bash
+# DNA mode (manifest's provider, or primary, or claude):
+kei agent critic "review src/auth.rs"
+
+# Override DNA — try the same agent on a different model for a second opinion:
+kei agent --on=grok critic "review src/auth.rs"
+kei agent --on=agy  critic "review src/auth.rs"
+kei agent --on=copilot critic "review src/auth.rs"
+
+# Explicit backend, no DNA lookup (legacy):
+kei run-via grok critic "review src/auth.rs"
+
+# Point at an arbitrary agent file:
+kei agent --on=grok --file=/tmp/my-agent.md "do the thing"
+
+# Native --agent flag (grok/claude only):
+KEI_NATIVE_AGENT=1 kei agent critic "review src/auth.rs"
+```
+
+## How it works
+
+1. Resolves backend from DNA (see above).
+2. Reads `~/.claude/agents/<agent-name>.md` (assembler-generated prompt).
+3. Strips YAML frontmatter.
+4. Composes with task: `<agent prompt>\n\n---\n\nTASK FOR THIS RUN:\n<task>`.
+5. Execs the backend's non-interactive CLI with the composed prompt.
+
+No agent file is modified. No new tokens are issued — subscription
+authentication is whatever each CLI uses (its own login / config dir).
+
+## When to use each
+
+This is a tool, not a recommendation. Each backend has different
+strengths; the substrate is agnostic about which you pick. Pick by:
+
+- **Familiarity** — the CLI you already use day-to-day.
+- **Subscription cost** — burn the one with cheaper marginal cost first.
+- **Specific feature** — e.g. `grok --agent` for native sub-agent
+  switching mid-conversation; `agy --sandbox` for terminal restriction.
+- **Independent second opinion** — same agent, different model, see if
+  conclusions diverge.
+
+## Orchestrator picker — `kei` no longer hardcodes claude
+
+Without args, `kei` reads `~/.claude/config/primary.toml` and execs that CLI.
+The picker lets you change it interactively:
+
+```bash
+kei pick               # interactive menu → set primary → launch it
+kei                    # splash → exec the configured primary
+kei --on=grok          # one-shot launch of grok (does NOT change primary)
+kei primary grok       # set default to grok (no launch)
+kei primary            # show current primary
+```
+
+The splash shows `primary CLI: <backend>` so you always know which orchestrator
+will start. If the chosen primary isn't installed, `kei` prints the install
+command and offers `kei pick` as recovery.
+
+## Cross-CLI sub-agent spawn via MCP — `spawn_agent`
+
+`kei-mcp` exposes a built-in `spawn_agent` MCP tool. Any CLI that connects
+to it as an MCP client can invoke KeiSeiKit agents on any backend, no matter
+what the orchestrator is:
+
+```jsonrpc
+{
+  "jsonrpc": "2.0",
+  "method": "tools/call",
+  "params": {
+    "name": "spawn_agent",
+    "arguments": {
+      "name": "critic",
+      "task": "review src/auth.rs for race conditions",
+      "on": "grok"
+    }
+  }
+}
+```
+
+Internally `spawn_agent` shells out to `kei-agent-cli.sh` with the same DNA
+resolution as `kei agent`. The `on` argument is optional — without it, the
+backend is picked from the agent's manifest, then `primary.toml`, then claude.
+
+**Why this matters:** Claude Code has a native `Agent` tool for sub-agent
+spawning. Grok / Antigravity / Copilot / Kimi do NOT have that surface
+natively — but they all support MCP. With `spawn_agent` exposed via kei-mcp,
+**every backend that speaks MCP gets KeiSeiKit's sub-agent capability**. So
+when Grok is your orchestrator, it can still spawn `critic` on Claude (or
+`code-implementer` on Antigravity, or anything else) — the orchestrator
+choice no longer caps your sub-agent surface.
+
+Wire kei-mcp into the orchestrator's MCP config (each CLI has its own):
+
+| CLI | MCP config |
+|---|---|
+| claude | `~/.claude/settings.json` `mcpServers` block |
+| grok | `~/.grok/config.json` (or check `grok --help`) |
+| agy | `~/.antigravity/mcp.json` (check `agy plugin list`) |
+| copilot | `~/.copilot/mcp.json` (check `copilot --help`) |
+| kimi | `kimi mcp add` subcommand |
+
+Point each at `<kit>/_primitives/_rust/target/release/kei-mcp` (built via
+`cargo build -p kei-mcp --release`).
+
+## Rule enforcement — see also: cross-CLI policy
+
+**Phase C delivered**: KeiSeiKit's safety hooks now have a 3-tier enforcement
+model across CLIs. See [cross-cli-policy.md](./cross-cli-policy.md) for the
+full matrix and `kei mcp-wire` setup. Short version: TIER 1 (full native)
+on claude+grok, TIER 2 (MCP-wrapped) on copilot, TIER 3 (advisory) on agy+kimi.
+
+## Rule enforcement caveat (READ THIS — pre-Phase-C view)
+
+KeiSeiKit hooks (`numeric-claims-guard`, `citation-verify`, `no-github-push`,
+`safety-guard`, `push-to-main`, etc.) are **Claude Code-side**:
+`PreToolUse:Bash` / `:Edit` / `:Write` events that fire inside Claude Code's
+process. They do **not** propagate to grok / agy / copilot / kimi.
+
+That means:
+- **Prompt-level rules** (the agent's instructions inside the `.md`) DO
+  carry through — the agent reads Constructor Pattern, Evidence Grading,
+  No Hallucination, etc. as part of its system prompt on any backend.
+- **Tool-level enforcement** (hard-deny on `git push github.com`,
+  citation guard, etc.) only applies on the **claude** backend. Other
+  backends' tool surfaces are governed by THEIR own hooks/policies.
+
+If you need true rule-enforcement on a non-claude backend, the path is
+the **MCP server** (`_primitives/_rust/kei-mcp/`): registers KeiSeiKit
+primitives as MCP tools that the other CLI invokes. Tool-side policies
+travel with the MCP wrapper, not with the CLI.
+
+## Adding a new backend
+
+1. Add a `[backend.<name>]` table to `_primitives/cli-backends.toml`.
+2. Add a case arm in `scripts/kei-agent-cli.sh` `backend_bin()` and
+   `backend_invoke()` for the new CLI's print-flag.
+3. Add a row to the smoke-test table above (state PASS/FAIL/PARTIAL).
+
+## What it is NOT
+
+- Not a router — picks no backend for you; you (or DNA) ask, it dispatches.
+- Not a federation — each backend runs independently with its own
+  context; there is no cross-backend state.
+- Not a rule-enforcement layer — hooks only fire on the claude backend
+  (see caveat above). For non-claude rule enforcement use MCP server.
+- Not a wrapper around the backend's tool surface — what the CLI can
+  do (Bash, file edits, MCP, etc.) is determined by that CLI, not
+  KeiSeiKit. The substrate only ships the prompt.
+
+## Related
+
+- `_primitives/_rust/kei-llm-router/` — Beta-posterior router for
+  *programmatic* model selection inside Rust code (a different layer).
+- `_primitives/_rust/kei-mcp/` — MCP server that exposes KeiSeiKit
+  primitives to ANY MCP-compatible client (Cursor / Continue / Zed /
+  Aider / Cline / Windsurf / OpenClaw).
