docs(friction): re-asked operator about push + execution mode (settled)

I re-surfaced two already-settled decisions as questions (push to origin; subagent
vs inline) at the M5 handoff. The existing execution-mode guard only matches the
writing-plans menu's literal text, so free-form prose re-asks slip through. Default:
push as backup and go subagent-driven without asking.

+# M5 — Mesh enrollment (NetBird agents) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** `ubongo` reachable from anywhere over the NetBird mesh — enrol NetBird agents on `ubongo` + `askari` via a new opt-in `base` `mesh` concern; the operator enrols the laptops.
+
+**Architecture:** A new `base` concern (`roles/base/tasks/mesh.yml`) installs a pinned NetBird agent and runs `netbird up` with a reusable scoped setup key from vault. Gated by `base__mesh_enabled` (per-host opt-in) and `base__mesh_manage` (skips network/daemon actions for Molecule). **No firewall change** — enrollment is additive (`wt0` comes up, SSH keeps listening), so there is zero lockout risk. The host nftables default-deny + NetBird ACL tightening are a separate, deferred follow-on.
+
+**Tech Stack:** NetBird agent (apt, pinned), Ansible (`base` role), Molecule, the M4b coordinator at `https://netbird.askari.wingu.me`.
+
+**Spec:** `docs/superpowers/specs/2026-06-17-m5-mesh-enrollment-design.md`
+
+**Execution context:** Tasks 1–4 author + commit (need nothing from the operator). **Task 5 is an operator handoff** (dashboard `/setup` + mint key). **Task 6 applies live to `ubongo` + `askari`** (gated). Task 7 is operator-only (laptops). Task 8 docs.

+### Task 1: Verify + pin the NetBird agent; add the `mesh` tag
+
+- [ ] **Step 1 (ADR-014 verification — record the answers):** confirm against current NetBird docs/repo (WebFetch `docs.netbird.io`, `pkgs.netbird.io`):
+  - the **apt repo** URL + signing-key URL + suite/component (the install-script publishes an apt source — capture the exact `deb` line and key URL);
+  - the **package name** (headless agent — expected `netbird`) and that **version `0.72.4`** (matching the coordinator) is installable, plus the apt **version-pin syntax**;
+  - the exact **`netbird status`** output string that indicates an established management connection (for the idempotency guard — e.g. `Management: Connected`);
+  - the **`netbird up`** flags (`--management-url`, `--setup-key`);
+  - whether the pinned NetBird's **default peer policy is allow-by-default** (decides §Task 6 step 4). Record all of this in the commit message / a note block.
+- [ ] **Step 2:** add `mesh` to `tests/tags.yml` under `concerns:`:
+```yaml
+  - mesh         # NetBird agent enrollment (ADR-016)
+```
+- [ ] **Step 3:** `make lint` → expect `check-tags: OK` (an unused vocab entry is allowed; nothing references it yet). Expected: 0 failures.
+- [ ] **Step 4:** commit `feat(base): add the 'mesh' concern tag (NetBird agent, ADR-016)`.
+
+---
+
+### Task 2: `base` `mesh` concern — defaults + tasks + include + README
+
+**Files:** `roles/base/defaults/main.yml`, `roles/base/tasks/mesh.yml` (create), `roles/base/tasks/main.yml`, `roles/base/README.md`.
+
+- [ ] **Step 1:** append the knobs to `roles/base/defaults/main.yml`:
+```yaml
+# NetBird mesh agent enrollment (ADR-016). Opt-in: default off so applying `base` to a
+# host not (yet) on the mesh is a no-op for this concern. The live actions (apt install
+# over the network, `netbird up` against the coordinator) are additionally gated by
+# base__mesh_manage so Molecule can exercise the wiring without a coordinator.
+base__mesh_enabled: false
+base__mesh_manage: true
+base__mesh_management_url: "https://netbird.askari.wingu.me"
+base__mesh_setup_key: "{{ vault.netbird.setup_key }}"   # noqa: var-naming[no-role-prefix] is NOT needed — this carries the base__ prefix
+base__mesh_version: "0.72.4"   # match the coordinator; confirmed installable in Task 1
+```
+- [ ] **Step 2:** create `roles/base/tasks/mesh.yml` (use the Task-1-verified repo URL/key/pin; the values below are the expected ones to confirm):
+```yaml
+---
+# NetBird agent enrollment (ADR-016). Additive only — no firewall change here.
+- name: Ensure /etc/apt/keyrings exists
+  ansible.builtin.file:
+    path: /etc/apt/keyrings
+    state: directory
+    mode: "0755"
+  tags: [mesh]
+
+- name: Add the NetBird APT GPG key
+  ansible.builtin.get_url:
+    url: https://pkgs.netbird.io/debian/public.key          # confirm in Task 1
+    dest: /etc/apt/keyrings/netbird.asc
+    mode: "0644"
+  when: base__mesh_manage | bool
+  tags: [mesh]
+
+- name: Add the NetBird APT repository
+  ansible.builtin.apt_repository:
+    repo: >-
+      deb [signed-by=/etc/apt/keyrings/netbird.asc]
+      https://pkgs.netbird.io/debian stable main             # confirm in Task 1
+    filename: netbird
+    state: present
+  when: base__mesh_manage | bool
+  tags: [mesh]

+- name: Install the NetBird agent (pinned)

+- name: Check current NetBird connection status
+  ansible.builtin.command: netbird status

+- name: Enrol this host in the mesh
+  ansible.builtin.command: >-

+    --management-url {{ base__mesh_management_url }}
+    --setup-key {{ base__mesh_setup_key }}
+  register: _netbird_up
+  changed_when: _netbird_up.rc == 0
+  when:
+    - base__mesh_manage | bool
+    - "'Management: Connected' not in (_netbird_status.stdout | default(''))"   # confirm string in Task 1
+  no_log: true   # setup key is on the argv
+  tags: [mesh]
+```
+- [ ] **Step 3:** in `roles/base/tasks/main.yml`, add the include (after the existing concerns), gated by `base__mesh_enabled`:
+```yaml
+- name: NetBird mesh enrollment
+  ansible.builtin.include_tasks:
+    file: mesh.yml
+    apply:
+      tags: [mesh]
+  when: base__mesh_enabled | bool
+  tags: [mesh]
+```
+- [ ] **Step 4:** document the concern in `roles/base/README.md` (purpose; the `base__mesh_*` knobs table; that it is additive/no-firewall; that the setup key comes from `vault.netbird.setup_key`; the `enabled`/`manage` gating).
+- [ ] **Step 5:** `make lint` → 0 failures. Commit `feat(base): NetBird agent enrollment concern (mesh)`.
+
+---
+
+### Task 3: Molecule coverage
+
+**Files:** `roles/base/molecule/default/converge.yml`, `roles/base/molecule/default/verify.yml`.
+
+> The concern is install + a daemon command needing a live coordinator, so the hermetic Molecule surface is thin (the known "render-only misses the real call" gotcha). Molecule proves: (a) enabling mesh with `manage: false` does not break the base converge and is idempotent; (b) `base__mesh_enabled: false` (the default, already exercised by the existing firewall test) is a clean no-op. Full install+enrol is proven live in Task 6.
+
+- [ ] **Step 1:** in `converge.yml` add to `vars:`:
+```yaml
+    base__mesh_enabled: true
+    base__mesh_manage: false          # skip network/daemon actions
+    base__mesh_setup_key: "dummy-molecule-key"
+```
+- [ ] **Step 2:** in `verify.yml` add a task asserting the concern is a clean no-op under `manage: false` — `netbird` is NOT installed and `wt0` does not exist (since all live actions are gated off):
+```yaml
+    - name: Confirm mesh manage=false did not install/enrol
+      ansible.builtin.command: which netbird
+      register: _nb
+      changed_when: false
+      failed_when: false
+    - name: Assert netbird absent under manage=false
+      ansible.builtin.assert:
+        that:
+          - _nb.rc != 0
+        fail_msg: "netbird should not be installed when base__mesh_manage is false"
+```
+- [ ] **Step 3:** `make test ROLE=base` → converge + idempotence + verify pass (`failed=0`). The existing firewall assertions still pass (mesh vars don't affect them).
+- [ ] **Step 4:** commit `test(base): molecule coverage for the mesh concern (manage-off no-op)`.
+
+---
+
+### Task 4: Vault stub + per-host opt-in
+
+- [ ] **Step 1 (vault — needs `rbw` unlocked):** `make decrypt FILE=inventories/production/group_vars/all/vault.yml`; add under `vault.netbird` (alongside `auth_secret`/`datastore_key`):
+```yaml
+    # Reusable, scoped (group "boma-hosts"), expiring NetBird setup key. Mint it in the
+    # dashboard (Setup Keys) AFTER the first-boot /setup admin exists. Consumed by the
+    # base 'mesh' concern. CHANGEME until the operator supplies it via `make edit-vault`.
+    setup_key: CHANGEME
+```
+`make encrypt FILE=...`; `make check-vault` → confirms structure + lists the `setup_key` CHANGEME.
+- [ ] **Step 2:** set the opt-in. In `inventories/production/group_vars/control/vars.yml` add `base__mesh_enabled: true` (ubongo). Create `inventories/production/group_vars/offsite_hosts/vars.yml`:
+```yaml
+---
+# askari is a NetBird peer as well as the coordinator host (ADR-016).
+base__mesh_enabled: true
+```
+- [ ] **Step 3:** `make lint` → 0 failures. Commit `feat(base): vault setup_key stub + enable mesh on ubongo + askari`.
+
+---
+
+### Task 5: Operator handoff — first-boot admin + setup key (GATED, operator does this)
+
+> Nothing here is automatable — the agent cannot create a dashboard admin or mint a key.
+
+- [ ] **Step 1 (operator):** browse `https://netbird.askari.wingu.me`, complete the one-time `/setup` to create the admin user, log in.
+- [ ] **Step 2 (operator):** create a **reusable** setup key, **scoped** to auto-assign peers to a `boma-hosts` group, with an **expiry**. Copy the key value.
+- [ ] **Step 3 (operator):** `make edit-vault` → replace `vault.netbird.setup_key`'s `CHANGEME` with the real key → `:wq` (re-encrypts) → `make check-vault` shows no outstanding CHANGEME. The key never enters the chat.
+- [ ] **Step 4:** no repo commit beyond the (already-encrypted) vault, which is unchanged on disk structure.
+
+---
+
+### Task 6: Enrol `ubongo` + `askari` (GATED, live — needs Task 5 done + `rbw` unlocked)
+
+- [ ] **Step 1:** `make check PLAYBOOK=site LIMIT=askari TAGS=mesh` — review (askari is `ansible`-user managed; cleaner first target than the control node). Then `make deploy PLAYBOOK=site LIMIT=askari TAGS=mesh`.
+- [ ] **Step 2:** verify on askari: `netbird status` shows `Management: Connected`; `ip link show wt0` exists. (Agent coexists with the coordinator container; it reaches the coordinator via the public URL.)
+- [ ] **Step 3:** `make check PLAYBOOK=site LIMIT=ubongo TAGS=mesh` — review. Note: ubongo is managed as `sjat` with `become: true` (same path `dev_env` used via `playbooks/workstation.yml`); confirm `sjat` sudo works (the run will prompt/fail clearly if a become password is needed). Then `make deploy PLAYBOOK=site LIMIT=ubongo TAGS=mesh`.
+- [ ] **Step 4:** verify the mesh link from ubongo: `netbird status` shows `ubongo` connected and lists `askari` as a peer; ping askari's NetBird (`100.x`) address. If the pinned NetBird is NOT allow-by-default (Task 1, Step 1), add one minimal dashboard policy permitting the admin group → `ubongo` SSH (or temporarily the default policy) so Task 7 can connect.
+- [ ] **Step 5:** no repo commit (host state).
+
+---
+
+### Task 7: Enrol the road-warrior clients → goal lands (operator)
+
+- [ ] **Step 1 (operator):** install the NetBird client on `mamba` + the work laptop; log in via the dashboard (Dex SSO) so they join the mesh.
+- [ ] **Step 2 (operator):** from a laptop (anywhere), `ssh sjat@<ubongo-netbird-ip>` (or the mesh hostname) — connection succeeds. **← the mobile-access goal lands here.**
+- [ ] **Step 3:** confirm with the operator that remote access works end-to-end.
+
+---
+
+### Task 8: Docs
+
+- [ ] **Step 1:** `STATUS.md` — move "NetBird agent enrollment in `base`" to **built + applied** (ubongo + askari enrolled; reachability achieved). Note the `mesh` concern + opt-in. ubongo row: mesh-enrolled (its other base concerns still pending). askari row: NetBird peer.
+- [ ] **Step 2:** `docs/ROADMAP.md` — **M5 ✅ DONE**; Phase 1 (remote access) complete. Next: the **Procurement gate** (`/capacity-review` → buy cluster hardware). Record the deferred "mesh hardening" follow-on (ubongo nftables default-deny + NetBird ACL tightening + askari SSH→`wt0`).
+- [ ] **Step 3:** `docs/FRICTION.md` — add a signal: a **docs-only commit still tripped the `rbw`-locked pre-commit guard** (2026-06-17), although the 2026-06-10 kaizen fix was meant to let docs-/config-only commits through without vault — the hook scoping or a blanket guard needs a look.
+- [ ] **Step 4:** `make lint`; commit `docs: M5 done — Phase 1 remote access complete`.
+
+---
+
+## Self-Review (completed)
+
+- **Spec coverage:** `mesh` concern (spec §1) → Tasks 1–3; vault stub (spec §2) → Task 4; ubongo+askari enrol (spec §3) → Tasks 4,6; laptops (spec §3) → Task 7; reachability via default policy (spec §4) → Task 6 step 4; deferred hardening (spec §6) → recorded in Task 8; operator handoff (spec) → Task 5. Testing (spec) → Task 3 (hermetic) + Task 6 (live). All covered.
+- **Placeholder scan:** the "confirm in Task 1" markers are ADR-014 verification points executed in Task 1 (the repo URL/key/pin/status-string), not vague TODOs — Task 2's code carries the expected values to confirm, matching how M4a/M4b pinned versions in-plan.
+- **Consistency:** `base__mesh_enabled` (opt-in) vs `base__mesh_manage` (test gate) used consistently across defaults, tasks, include, converge, and the no-op assertion; `vault.netbird.setup_key` matches between defaults, vault stub, and Task 5; `mesh` tag added (Task 1) before it is used (Task 2).
+- **Risk:** the only live risk is Task 6 on the control node — mitigated because the `mesh` concern makes **no firewall change** (SSH stays open on all paths), askari is enrolled first as the lower-risk rehearsal, and the host nftables lockdown is explicitly out of scope.

+# M5 — Mesh enrollment (NetBird agents) → mobile access · design
+
+**Status:** Design (2026-06-17). Implements ROADMAP **M5**, the last milestone of Phase 1
+(remote access). Builds on M4b (the `netbird_coordinator` is live on `askari`). Design
+resolved by **ADR-016** (mesh, agent-per-host) and **ADR-021** (SSH ladder); this spec is
+the build-shaping for that decision. Next: `writing-plans`.
+
+## Goal
+
+`ubongo` reachable from anywhere over the self-hosted NetBird mesh — the Phase-1
+mobile-access goal. **Reachability only.** The host-firewall lockdown and NetBird
+ACL-tightening are deliberately **deferred** (see §6).
+
+## Decisions (settled in brainstorming)
+
+1. **Scope = reachability, not lockdown.** The goal needs only: agents enrolled + the
+   laptops on the mesh + a peer policy permitting laptop→`ubongo`. `ubongo`'s SSH is
+   already open, so reachability requires **no firewall change**. Applying the `base`
+   nftables default-deny to `ubongo` is the lockout-risky part on the control node and is
+   split into a follow-on (§6).
+2. **One reusable, scoped, expiring setup key.** A single reusable key in
+   `vault.netbird.setup_key`, scoped to auto-assign peers to a `boma-hosts` group, with an
+   expiry. `base` re-runs idempotently across hosts. Matches ADR-016's single vault path;
+   blast radius is limited by scope + expiry + the fact that joining the mesh grants no
+   access on its own (peer policy gates that). Rejected: per-host one-off ephemeral keys —
+   more operator toil and they don't fit a single vault key for a re-runnable role.
+3. **`askari` is enrolled as a peer** (ADR-016: it runs the stack *and* is a peer). The
+   agent coexists with the coordinator container on the same host. Enables later moving
+   `askari`'s SSH off the Hetzner-firewall WAN allow onto `wt0`, and gives a host-to-host
+   mesh link verifiable from `ubongo`.
+
+## Architecture
+
+### 1. New `base` concern: `mesh` (agent enrollment)
+
+A new `roles/base/tasks/mesh.yml`, included from `base/tasks/main.yml` via
+`include_tasks` with `apply: { tags: [mesh] }` (the dynamic-include tag-propagation
+gotcha — see existing concerns), tagged `mesh`. A new `mesh` entry is added to the closed
+tag vocabulary in `tests/tags.yml`.
+
+The concern:
+
+- **installs a pinned NetBird agent** from the official NetBird apt repo (repo + key added
+  like `docker_host` does for Docker; exact package + version **verified in the plan** per
+  ADR-014). Version-pinned (ADR-011).
+- **enrolls idempotently:** run `netbird up --management-url {{ base__mesh_management_url }}
+  --setup-key <key>` **only when** `netbird status` reports the host is not already
+  connected (guard on a `command` check, `changed_when` accordingly). The setup key is
+  passed with `no_log: true`.
+- **does NOT touch the host firewall.** Enrollment is purely additive: `wt0` comes up,
+  `sshd` keeps listening on all interfaces exactly as today. No lockout risk in M5.
+
+**Knobs (`base__mesh_*`, defaults in `roles/base/defaults/main.yml`):**
+
+| Var | Default | Purpose |
+|---|---|---|
+| `base__mesh_enabled` | `false` | **Policy/opt-in gate.** `false` ⇒ the whole concern is skipped, so applying `base` to a host not ready to join the mesh is a no-op. Set `true` per host/group (`ubongo`, `askari`) to enrol. |
+| `base__mesh_manage` | `true` | **Test gate** for the live daemon step. `true` ⇒ run `netbird up`; Molecule sets `false` so the concern can be exercised without a real coordinator/key (mirrors `reverse_proxy__manage` / `netbird_coordinator__manage`). |
+| `base__mesh_management_url` | `https://netbird.askari.wingu.me` | The M4b coordinator. |
+| `base__mesh_setup_key` | `"{{ vault.netbird.setup_key }}"` | Reusable scoped key (vault). |
+| `base__mesh_version` | pinned (plan) | NetBird agent version (ADR-011). |
+
+### 2. Vault
+
+Add `vault.netbird.setup_key: CHANGEME` with a comment stating it is a **reusable, scoped
+(`boma-hosts`), expiring** setup key minted in the NetBird dashboard after first-boot
+`/setup`. The agent cannot mint it — the operator supplies it via `make edit-vault`.
+`make check-vault` lists the outstanding `CHANGEME` until then. `base/tasks/mesh.yml` wires
+to `{{ vault.netbird.setup_key }}`.
+
+### 3. Enrollment scope
+
+- **`ubongo`** — `base` `mesh` concern applied (tagged), bringing up `wt0`. Its other
+  `base` concerns (`firewall`, `hardening`) stay unapplied — `TAGS=mesh` scopes the run to
+  enrollment only, so no default-deny lands on the control node.
+- **`askari`** — `base` `mesh` concern applied; agent enrols against its own public
+  coordinator URL and coexists with the coordinator container.
+- **`mamba` + work laptop** — **operator** installs the NetBird client and logs in via the
+  dashboard (embedded Dex SSO). Not Ansible-managed; out of automation scope.
+
+### 4. Reachability
+
+M5 relies on NetBird's **default peer policy** for laptop→`ubongo` reachability. The plan
+**verifies the pinned version's default-policy behaviour** (ADR-014); if it is not
+allow-by-default, the plan adds one minimal policy permitting the admin group → `ubongo`
+SSH. ACL-tightening to default-deny + scoped policies (ADR-016 intent) is **deferred**
+(§6).
+
+## Testing
+
+- **Automated (I do, needs nothing from operator):** Molecule for the `base` `mesh`
+  concern with `base__mesh_enabled: true`, `base__mesh_manage: false`, and a dummy
+  `vault.netbird.setup_key` — so the install/enrol tasks are exercised but the live
+  `netbird up` (which needs a real coordinator + key) is gated off. Note: this concern is
+  install + a daemon command, so its render-only surface is thin (the "render-only tests
+  miss the real call" gotcha) — Molecule asserts the enrol command is constructed
+  correctly + idempotency guard works; full enrollment is proven in the live step below.
+  Also assert `base__mesh_enabled: false` is a clean no-op. `make lint` (incl.
+  `check-tags` for the new `mesh` tag).
+- **Live (gated, after the operator handoff):** apply `base` `TAGS=mesh` to `ubongo` +
+  `askari`; verify `wt0` is up and the **`ubongo`↔`askari` mesh link** works from `ubongo`
+  (both are peers I manage — e.g. `netbird status` shows the peer, ping the peer's mesh IP).
+- **Goal verification (operator):** from a laptop on the mesh, SSH `ubongo` over its
+  NetBird/`wt0` address. This is the mobile-access goal landing.
+
+## Operator handoff (the steps only the operator can do)
+
+1. Dashboard `/setup` (one-time) → create the admin user.
+2. Mint a **reusable, scoped (`boma-hosts`), expiring** setup key → `make edit-vault` to
+   replace the `CHANGEME` → re-encrypt. (`make check-vault` confirms.)
+3. Install the NetBird client on `mamba` + the work laptop, log in via the dashboard.
+4. Confirm SSH to `ubongo` over the mesh.
+
+## Out of scope / deferred (the "mesh hardening" follow-on)
+
+- **`base` nftables default-deny on `ubongo`** (SSH only on `wt0` + the
+  `base__firewall_control_addr` LAN fallback, ADR-021/020). Built + dormant today; applying
+  it to the control node is the lockout-risky step and gets its own deliberate change
+  **after** the mesh path to `ubongo` is proven solid.
+- **NetBird ACL tightening** to default-deny + scoped per-group policies (ADR-016: admin
+  peers → `srv`+`mgmt`, clients least-privilege). M5 uses the default policy.
+- **`askari` SSH onto `wt0`** (retiring the Hetzner-firewall WAN SSH allow) — enabled by
+  `askari` now being a peer, but a separate change.

+ADR-016 (mesh, agent-per-host, setup keys in vault), ADR-021 (SSH ladder — `wt0` primary +
+`ssh-from-control`; the lockdown that *uses* this is deferred), ADR-020 (host firewall —
+default-deny deferred), ADR-002 (security baseline), ADR-011 (version-pinned agent),
+ADR-004 (enrollment lives in `base`, not a new role), ADR-014 (verify agent
