+# Node credential hot-reload + Nodes-page status dot and filters
+
+Date: 2026-10-10
+Status: approved design, pre-implementation
+Scope: `apps/node/agent` (daemon), `apps/server/web` (Nodes page). One change set,
+two independently shippable parts (A ships in a node release, B in a server build).
+
+## Problem
+
+### A — re-registration silently no-ops against a running daemon
+
+Incident (2026-10-10, operator machine): a node row was re-registered from the
+dashboard; `install.sh → subshell setup` enrolled fresh credentials, printed
+`Enrolled as …`, `subshell is enabled and running`, `done.` — and the node stayed
+offline forever. The daemon (started 14:51 with the previous credentials) never
+loaded the config the installer wrote at 16:41; it reconnect-looped with the
+superseded bearer until a manual `systemctl --user restart`.
+
+Mechanics, all verified at current `main`:
+
+- `runSetup` (`apps/node/agent/src/setup.ts:215`) enrolls (rewriting
+  `config.json`) and then calls `installService`.
+- `installService` on Linux runs `systemctl --user enable --now`
+  (`apps/node/agent/src/service.ts:~380`) — **`--now` on an active unit is a
+  no-op**, so the live daemon keeps its boot-time config object.
+- The dial reads the boot snapshot: `daemon.ts:890` and `daemon.ts:1229`
+  construct the WebSocket with `config.nodeKey` from the object loaded at start;
+  nothing re-reads config for the connection path.
+- `service restart` deliberately refuses without `--force` because restart kills
+  live panes (`service.ts:1267-1269`). That doctrine is kept: **nothing here
+  restarts the process.**
+
+Related facts this design rides on:
+
+- `HEARTBEAT_MS = 15_000` (`daemon.ts:74`) — a beat already runs in steady state.
+- `daemon.lock` is refreshed with `config.nodeId` (`daemon.ts:600`, doc at 397) —
+  the lock must follow any identity swap or `status` lies.
+- The retention pass already establishes live-reload doctrine: it "re-resolves
+  the stored layer from `config.json` every run … lands on the next hourly sweep
+  without a restart" (`daemon.ts:522-533`). Credentials get the same posture on
+  the faster beat.
+- A healthy daemon that is merely *reconnected* would also pick up on-disk
+  config; a watcher (`fs.watch`) would go deaf on inode-replacing writers
+  (the common Linux case) and needs a poll fallback anyway — the beat check is
+  the same mechanism without the extra lifecycle.
+
+### B — Nodes list: offline is invisible and the fleet is unfilterable
+
+- Offline renders as `<Badge variant="muted">offline</Badge>`
+  (`apps/server/web/src/components/nodes/node-row.tsx:127`), visually equal to
+  the gray OS/arch chip beside it — an operator missed exactly this while a node
+  sat dead for hours.
+- The list has no search or filters; every other scannable surface in the app
+  (`routes/index.tsx`) has search + a machine `Select` composed through a pure
+  lib (`lib/subshell-filter.ts`).
+- Subshells already settled this exact design question: on 2026-09-24 the home
+  cards and list rows **replaced text status chips with the 6px `SubshellDot`**,
+  with an operator ruling that node-offline is **red, not amber** ("a machine you
+  cannot reach is an error state, not a caution", `subshell-dot.tsx` header).
+  The Nodes page adopts the same state language.
+
+## Design
+
+### A — credential hot-reload on the heartbeat beat
+
+**Contract:** a config written while the daemon runs lands on the next beat
+(≤15 s) without a restart and without touching panes; a config that cannot be
+read or parsed is a warn line and the connection keeps yesterday's working
+bundle; the swap is atomic per connection-identity bundle.
+
+1. On each heartbeat beat (same tick that refreshes `daemon.lock`), read and
+   parse `config.json` and compare the **connection-affecting fields**:
+   `serverUrl`, `nodeId`, `nodeKey`, `encryptKeyPair`,
+   `controlEncryptPublicKey`, `controlPublicKey`. The criterion is
+   **field equality**, not file-byte equality — a reformat/key-reorder must not
+   cost a redial, and a field change hidden by formatting must not slip past.
+   No field difference → nothing.
+2. On difference → log `config changed; reconnecting as <new nodeId>`, close
+   the plane WebSocket *without* entering the reconnect backoff, and redial
+   using a **newly loaded config bundle** swapped in as one object. The lock
+   write, heartbeat payloads, and `setDaemonState` all read the swapped bundle.
+3. Failure handling: read/parse/validation failure → single warn line per
+   change attempt (`config reload failed: …; keeping the running identity`),
+   last-good bundle stays, retried on the next beat. A bad write mid-flight can
+   therefore never drop a healthy connection's ability to keep working — worst
+   case is the status quo (offline, loudly logged).
+4. Non-connection fields (name, dataDir, retention settings) never trigger a
+   redial; existing consumers of those keep their own resolution points.
+5. The `set-server-url` command takes the same path for free (it only edits the
+   config on disk today — with this it lands live).
+6. Implementation-time verification (not a design choice): locate every capture
+   of the boot `config` object reachable from the dial/crypto path
+   (`link-crypto.ts:240-241` builds envelopes per-message from `config`;
+   confirm the instance does not pin the old object anywhere) so the swap is
+   genuinely atomic — plan must enumerate the sites.
+
+**Why not installer-side fixes:** a silent restart violates the pane doctrine;
+a loud "restart required" message leaves every honest install still printing
+"done." while offline. Hot-reload makes the original message true.
+
+**Tests** (daemon's injectable-deps style, `apps/node/agent/src/__tests__/`):
+
+- healthy socket + config write with new id/key → exactly one controlled
+  reconnect, dial headers carry the new `nodeKey`, `daemon.lock` and
+  `status` report the new id, and **zero** pane-teardown calls.
+- unparsable config written after a good one → warn line, connection stays,
+  a subsequent valid write lands.
+- byte-identical rewrite (touch, same content) → no reconnect.
+- non-connection field change only (e.g. `name`) → no reconnect.
+- `serverUrl` change → redials at the new URL.
+
+### B — Nodes page: dot instead of chip, plus filters
+
+**Status dot (tiles and table rows):**
+
+- Remove the `online/offline` `Badge` from `node-row.tsx` and the equivalent
+  cell in `node-table.tsx`.
+- New `NodeStatusDot` — 6px (`h-1.5 w-1.5 rounded-full`), same geometry as
+  `SubshellDot`, colors from the same tokens: online → `bg-success`, offline →
+  `bg-destructive`. It sits **before the node name** in the identity column.
+  No blink (a node is not "working"), no amber tier — deliberately matching the
+  subshell standard, including its no-caution-for-unreachable ruling.
+- It is a node-domain component, not an import of `SubshellIndicator`
+  (different state space); a later unification into a shared Dot primitive is
+  welcome but out of scope. If the unmerged `status-dot-badges` branch lands
+  first, rebase onto its primitives rather than forking colors.
+- Accessibility: on the subshell rail the dot is `aria-hidden` because the row
+  text carries state; here the chip is gone, so the dot is the **only** carrier
+  → render with `role="img"`, `aria-label` and `title` = `online` /
+  `offline · seen <relative>` (the seen-time joins the words the chip's line
+  already had; `maintenance`/`inventory stale` chips remain separate, they are
+  warnings and warnings never hide).
+- The hostname line keeps `· seen …· v…` unchanged.
+
+**Filters (both `tiles` and `list` views; `keys` tab untouched):**
+
+- Toolbar above the list, aligned to the home page's pattern:
+  - Search `Input` — case-insensitive substring across `name` and `hostname`
+    (fallback `id` when hostname is null, matching what the row displays).
+    Placeholder: `Search by name or hostname…`.
+  - Status `Select`: All / Online / Offline.
+  - Access `Select`: All / Yours / Shared (`access === "owner"` vs not — the
+    same reading the `yours` / `shared · <access>` chips use).
+- AND-composed. Page state, not URL (home precedent: "the machine filter is
+  page-level"; the existing tab stays URL-encoded as is). Filters apply
+  identically to both views; counts above the list (if shown) reflect
+  filtered/total.
+- Zero-match empty state: "No nodes match" + a `Clear filters` action that
+  resets all three (distinct from the existing "No nodes yet" state, which is
+  about enrollment, not filtering).
+- Pure helper `lib/node-filter.ts` (`filterNodes(nodes, { query, status,
+  access })`) mirroring `lib/subshell-filter.ts`; all logic lives there.
+
+**Tests:**
+
+- vitest for `node-filter.ts`: each axis alone, AND-combination, null-hostname
+  fallback, empty results, no mutation of input.
+- Nodes-page component test (pattern: `routes/__tests__/nodes-page-gate.test.tsx`):
+  offline node renders `bg-destructive` dot and no status chip; dot exposes the
+  aria label; filtering to "Online" hides the offline row; zero-match shows
+  Clear filters.
+
+## Out of scope
+
+- The install-time "verify the daemon actually connected before printing done"
+  step (hot-reload makes the current message true; a verification probe is a
+  separate contract with the plane).
+- `installService`'s wording; `service restart`'s pane doctrine (unchanged).
+- The unmerged `status-dot-badges` branch's home-page concerns.
+- Any pricing/credit surface — Part A/B touch none.
+
+## Success criteria
+
+- Reproducing the incident (re-register a running, healthy node) leaves the
+  plane-connected within one beat (~15 s) with zero operator action and zero
+  pane loss; `daemon.lock`/`status` show the new id.
+- An offline node is unmistakable on the Nodes page at a glance, screen readers
+  hear its state, and an operator with a mixed fleet can reach
+  search+status+shared in one click each with results in the URL-stable tab UX.

+# Node credential hot-reload + Nodes status dot and filters — 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 for tracking.
+
+**Goal:** Make on-disk credential changes land in a running node daemon without a restart (fixing silent re-register no-ops), and make the Nodes page legible: a status dot replacing the invisible chip, plus search/status/shared filters.
+
+**Architecture:** Part A adds two pure helpers to the agent's `config.ts` (identity comparison + in-place field swap) and a single `refreshConnectionConfig()` seam in `daemon.ts` called from the heartbeat beat (healthy connections) and the reconnect loop (stuck daemons — the incident shape). Part B adds a pure `node-filter.ts` lib, a `NodeStatusDot` component wired into both Nodes views, and a filter toolbar in `routes/nodes.tsx`.
+
+**Tech stack:** Bun + TypeScript; `bun:test` everywhere (both apps); React + Tailwind tokens on the web side.
+
+**Spec:** `docs/superpowers/specs/2026-10-10-node-credential-hot-reload-and-node-filters-design.md`
+
+## Global Constraints
+
+- Work happens ONLY in the worktree `/home/theo/subshell-worktrees/node-onboarding-and-filters` (branch `fix/node-reregister-and-filters`).
+- Tests: `bun test` (NOT vitest). Agent app: `cd apps/node/agent && bun test src/__tests__/<file>.ts`. Web app: `cd apps/server/web && bun test src/<path>/<file>.test.tsx`.
+- Log lines must NEVER print `nodeKey` or any config secret; the change log names the **nodeId** only.
+- Nothing in this plan may stop/restart the daemon process or kill panes (the repo's pane doctrine; `service restart` stays `--force`-gated).
+- Copy rule: no em dashes in user-facing strings (use `·` middots, matching existing badge/dot copy).
+- Reload criterion is **field equality** on parsed values, never file-byte equality.
+- Commit after every green task; lefthook runs biome automatically — stage explicit paths only.

+
+### Task A1: connection-identity helpers in `config.ts`
+
+**Files:**
+- Modify: `apps/node/agent/src/config.ts`
+- Create: `apps/node/agent/src/__tests__/config-connection.test.ts`
+
+**Interfaces:**
+- Consumes: existing `NodeConfig` (fields `serverUrl`, `nodeWsUrl?`, `nodeId`, `nodeKey`, `controlPublicKey`, `controlEncryptPublicKey?`, `encryptKeyPair?: {publicKey; privateKey}`).
+- Produces: `connectionIdentity(c: NodeConfig): string`, `applyConnectionFields(target: NodeConfig, source: NodeConfig): void` — used by Task A2.
+
+- [ ] **Step 1: Write the failing tests**
+
+Create `apps/node/agent/src/__tests__/config-connection.test.ts`:
+
+```ts
+import { describe, expect, test } from "bun:test";
+import { type NodeConfig, applyConnectionFields, connectionIdentity } from "../config.js";
+
+const BASE: NodeConfig = {
+  serverUrl: "https://plane.example",
+  nodeWsUrl: "wss://plane.example/ws/node",
+  nodeId: "node-a",
+  nodeKey: "subshell_key_a",
+  controlPublicKey: '{"kty":"EC"}',
+  controlEncryptPublicKey: "AAAA",
+  encryptKeyPair: { publicKey: "PUB", privateKey: "PRIV" },
+  dataDir: "/tmp/ignored-by-identity",
+  name: "box",
+} as NodeConfig;
+
+describe("connectionIdentity", () => {
+  test("stable for a byte-identical or reordered-but-equal config", () => {
+    expect(connectionIdentity(BASE)).toBe(connectionIdentity({ ...BASE }));
+    // Key order inside the keypair must not read as a change.
+    expect(connectionIdentity({ ...BASE, encryptKeyPair: { privateKey: "PRIV", publicKey: "PUB" } })).toBe(
+      connectionIdentity(BASE),
+    );
+  });
+  test("changes when any connection field changes", () => {
+    for (const patch of [
+      { nodeId: "node-b" },
+      { nodeKey: "subshell_key_b" },
+      { serverUrl: "https://other.example" },
+      { nodeWsUrl: undefined },
+      { controlEncryptPublicKey: "BBBB" },
+      { encryptKeyPair: { publicKey: "PUB", privateKey: "OTHER" } },
+    ]) {
+      expect(connectionIdentity({ ...BASE, ...(patch as Partial<NodeConfig>) })).not.toBe(connectionIdentity(BASE));
+    }
+  });
+  test("ignores non-connection fields", () => {
+    expect(connectionIdentity({ ...BASE, name: "renamed", dataDir: "/elsewhere" })).toBe(connectionIdentity(BASE));
+  });
+});
+
+describe("applyConnectionFields", () => {
+  test("copies connection fields in place and leaves others alone", () => {
+    const live = { ...BASE };
+    applyConnectionFields(live, { ...BASE, nodeId: "node-b", nodeKey: "subshell_key_b", name: "different" });
+    expect(live.nodeId).toBe("node-b");
+    expect(live.nodeKey).toBe("subshell_key_b");
+    expect(live.name).toBe("box"); // NON-connection fields are never touched
+  });
+  test("removes optional fields the disk no longer carries", () => {
+    const live = { ...BASE };
+    applyConnectionFields(live, { ...BASE, nodeWsUrl: undefined, encryptKeyPair: undefined });
+    expect(live.nodeWsUrl).toBeUndefined();
+    expect(live.encryptKeyPair).toBeUndefined();
+    expect(live.nodeId).toBe("node-a"); // unchanged fields survive
+  });
+});
+```
+
+- [ ] **Step 2: Run to verify they fail**
+
+Run: `cd apps/node/agent && bun test src/__tests__/config-connection.test.ts`
+Expected: FAIL — `applyConnectionFields` / `connectionIdentity` are not exported.
+
+- [ ] **Step 3: Implement**
+
+Append to `apps/node/agent/src/config.ts` (after the `NodeConfig` interface / near `loadConfig`):
+
+```ts
+/**
+ * The fields whose on-disk change means the LIVE connection identity of a
+ * running daemon is stale (design 2026-10-10 §A): everything needed to dial,
+ * authenticate, and seal a link. Non-connection fields (name, dataDir, …) are
+ * deliberately excluded — they must never cost a redial.
+ */
+export function connectionIdentity(c: NodeConfig): string {
+  return JSON.stringify([
+    c.serverUrl,
+    c.nodeWsUrl ?? null,
+    c.nodeId,
+    c.nodeKey,
+    c.controlPublicKey,
+    c.controlEncryptPublicKey ?? null,
+    // Explicit tuple, not object order: a key-order-only reformat is not a change.
+    c.encryptKeyPair ? [c.encryptKeyPair.publicKey, c.encryptKeyPair.privateKey] : null,
+  ]);
+}
+
+/**
+ * In-place swap of exactly the connection fields from `source` onto `target`.
+ * In-place because every consumer of the daemon's config holds THIS object
+ * (`persistLink` in daemon.ts established the discipline); replacing the
+ * reference would strand half the closures on the old bundle. Fields the disk
+ * no longer carries are deleted, never left stale.
+ */
+export function applyConnectionFields(target: NodeConfig, source: NodeConfig): void {
+  const t = target as unknown as Record<string, unknown>;
+  const s = source as unknown as Record<string, unknown>;
+  for (const key of ["serverUrl", "nodeWsUrl", "nodeId", "nodeKey", "controlPublicKey", "controlEncryptPublicKey", "encryptKeyPair"] as const) {
+    const value = s[key];
+    if (value === undefined) delete t[key];
+    else t[key] = value;
+  }
+}
+```
+
+- [ ] **Step 4: Run to verify green**
+
+Run: `cd apps/node/agent && bun test src/__tests__/config-connection.test.ts`
+Expected: all pass. Also re-run the existing config suite to catch regressions: `bun test src/__tests__/ -t config` — if that selects nothing, run `bun test src/__tests__/config.test.ts` only if the file exists; otherwise skip (the new file is the coverage).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add apps/node/agent/src/config.ts apps/node/agent/src/__tests__/config-connection.test.ts
+git commit -m "feat(node): connection-identity compare and in-place field swap for config hot-reload"
+```
+
+---
+
+### Task A2: daemon `refreshConnectionConfig()` at both seams
+
+**Files:**
+- Modify: `apps/node/agent/src/daemon.ts` (dial URL per-connection ~:411/:890/:981; pinned-key const :423/:810; new refresh after `writeLiveness` ~:600; heartbeat call ~:1043; loop seam ~:1133)
+- Modify: `apps/node/agent/src/__tests__/daemon.test.ts` (four new tests)
+
+**Interfaces:**
+- Consumes: `connectionIdentity`, `applyConnectionFields` (Task A1), existing `loadConfig`, `resolveWsUrl`, `parsePinnedKey`, `setDaemonState`, `log`.
+- Produces: behavior only — no new exports.
+
+- [ ] **Step 1: Write the failing tests**
+
+Append to `apps/node/agent/src/__tests__/daemon.test.ts` (module-level, beside the other `test(...)` blocks — `startDaemon`, `waitUntil`, `sleep`, `closeAllSockets`, `readFileSync`, `lockPath`, `saveConfig`, `configPath`, `captureLogs`, `NODE_KEY` are all in scope in that file):
+
+```ts
+test("config flip on disk reconnects within a beat without a process restart", async () => {
+  const logs = captureLogs();
+  const h = await startDaemon({ heartbeatMs: 30 });
+  const openedBefore = h.plane.opens;
+  saveConfig({ ...h.config, nodeId: "flipped-node-id" });
+  await waitUntil(() => h.plane.opens > openedBefore, "redial after config flip");
+  expect(logs.lines.some((l) => l.includes("config changed; reconnecting as node flipped-node-id"))).toBe(true);
+  expect(logs.lines.some((l) => l.includes(NODE_KEY))).toBe(false); // the bearer never reaches the log
+  const lock = JSON.parse(readFileSync(lockPath(), "utf8")) as { nodeId: string };
+  expect(lock.nodeId).toBe("flipped-node-id"); // daemon.lock followed the swap
+  logs.restore();
+});
+
+test("a stuck-between-dials daemon picks up a rewritten config on its next dial (re-register incident)", async () => {
+  const logs = captureLogs();
+  const h = await startDaemon({ heartbeatMs: 10_000 }); // no beat: exercise the LOOP seam only
+  const openedBefore = h.plane.opens;
+  saveConfig({ ...h.config, nodeId: "loop-flipped" });
+  closeAllSockets(h.plane, 1012, "force a redial"); // the incident shape: no live socket, backoff dials
+  await waitUntil(() => logs.lines.some((l) => l.includes("config changed; reconnecting as node loop-flipped")) &&
+    h.plane.opens > openedBefore, "loop-seam reload");
+  logs.restore();
+});
+
+test("unparsable config on disk is one warn line and keeps the live connection", async () => {
+  const logs = captureLogs();
+  const h = await startDaemon({ heartbeatMs: 30 });
+  writeFileSync(configPath(), "{ this is not json", { mode: 0o600 });
+  await sleep(120); // several beats against the broken file
+  expect(h.plane.opens).toBe(1); // no controlled close, no chaos
+  const warns = logs.lines.filter((l) => l.includes("config reload failed"));
+  expect(warns.length).toBe(1); // deduped: one line, not one per beat
+  expect(logs.lines.some((l) => l.includes("keeping the running identity"))).toBe(true);
+  saveConfig({ ...h.config, nodeId: "after-good-write" }); // a good write after the bad one lands
+  await waitUntil(() => logs.lines.some((l) => l.includes("reconnecting as node after-good-write")), "recover");
+  logs.restore();
+});
+
+test("a formatting-only config rewrite (same fields, reordered keys) costs no redial", async () => {
+  const h = await startDaemon({ heartbeatMs: 30 });
+  const raw = JSON.parse(readFileSync(configPath(), "utf8")) as Record<string, unknown>;
+  const reordered: Record<string, unknown> = {};
+  for (const key of Object.keys(raw).reverse()) reordered[key] = raw[key];
+  writeFileSync(configPath(), JSON.stringify(reordered, null, 7), { mode: 0o600 });
+  await sleep(150); // several beats against a byte-different, field-identical file
+  expect(h.plane.opens).toBe(1);
+});
+```
+
+(`writeFileSync`, `readFileSync` are already imported at the top of the file; `saveConfig`/`configPath` too.)
+
+- [ ] **Step 2: Run to verify the first three fail**
+
+Run: `cd apps/node/agent && bun test src/__tests__/daemon.test.ts`
+Expected: the four new tests fail (no reconnect happens / no warn lines); all pre-existing tests still pass.
+
+- [ ] **Step 3: Implement the daemon changes**
+
+All edits in `apps/node/agent/src/daemon.ts`:
+
+a) Import line :24 — extend the config import:
+
+```ts
+import { applyConnectionFields, connectionIdentity, loadConfig, type NodeConfig, updateConfig } from "./config.js";
+```
+
+b) Delete the boot-time `wsUrl` constant (:411) — the `runConnection` dial computes it fresh (this is what makes a `serverUrl`/`nodeWsUrl` swap land):
+
+```ts
+// REMOVED: const wsUrl = resolveWsUrl(config); // persisted-at-enroll URL wins (ledger 17c)
+// (dial resolves per-connection now — see runConnection)
+```
+
+Inside `runConnection` (the `new WebSocketImpl(wsUrl, ...)` at ~:890), replace the three `wsUrl` uses:
+
+```ts
+      const dialUrl = resolveWsUrl(config); // per-DIAL: a hot-swapped serverUrl must land here
+      try {
+        ws = new WebSocketImpl(dialUrl, { headers: { Authorization: `Bearer ${config.nodeKey}` } });
+      } catch (err) {
+        reject(new Error(`cannot open ${dialUrl}: ${err instanceof Error ? err.message : String(err)}`));
+        return;
+      }
+```
+
+and the open-listener log (~:981): `log(`connected ${dialUrl} as node ${config.nodeId}`);`
+
+c) The pinned control key becomes re-assignable (:423 and its use at :810):
+
+```ts
+  let pinnedControlKey = parsePinnedKey(config.controlPublicKey); // re-parsed on a hot swap
+```
+
+and at the `verifyCommand` call (:810) pass `pinnedControlKey` instead of `controlPublicKey`.
+
+d) Add the refresh seam immediately AFTER the `writeLiveness` definition + initial call (~:606):
+
+```ts
+  // Hot-reload of the connection identity (design 2026-10-10 §A). config.json is
+  // the live home of the node's credentials, and three writers rewrite it while
+  // this process runs: `subshell setup` (re-registration), `set-server-url`, and
+  // §5's register self-heal. Each beat and each between-dials moment compares the
+  // connection-affecting fields (parsed-value equality, never file bytes); on a
+  // real change the fields are swapped IN PLACE — every consumer holds this same
+  // object, the discipline `persistLink` already follows — and the caller hands
+  // the reconnect loop a fresh dial. A config the loader rejects costs ONE warn
+  // line (deduped by message) and the running identity, never a dropped socket:
+  // a bad write can only ever preserve the status quo. The log names the nodeId
+  // only — the bearer key must never reach a log line.
+  let liveIdentity = connectionIdentity(config);
+  let lastBadConfig = "";
+  const refreshConnectionConfig = (): boolean => {
+    let fresh: NodeConfig;
+    try {
+      fresh = loadConfig();
+    } catch (err) {
+      const detail = err instanceof Error ? err.message : String(err);
+      if (detail !== lastBadConfig) {
+        lastBadConfig = detail;
+        log(`config reload failed: ${detail}; keeping the running identity`);
+      }
+      return false;
+    }
+    const next = connectionIdentity(fresh);
+    if (next === liveIdentity) return false;
+    let pinned: typeof pinnedControlKey;
+    try {
+      pinned = parsePinnedKey(fresh.controlPublicKey);
+    } catch (err) {
+      const detail = err instanceof Error ? err.message : String(err);
+      if (detail !== lastBadConfig) {
+        lastBadConfig = detail;
+        log(`config reload failed: control key unparsable (${detail}); keeping the running identity`);
+      }
+      return false; // whole-bundle rule: a swap half-applied is worse than none
+    }
+    lastBadConfig = "";
+    liveIdentity = next;
+    applyConnectionFields(config, fresh);
+    pinnedControlKey = pinned;
+    setDaemonState({ serverUrl: config.serverUrl, nodeId: config.nodeId });
+    log(`config changed; reconnecting as node ${config.nodeId}`);
+    return true;
+  };
+```
+
+(`lastBadConfig` resets exactly once — the line in the snippet after both parses succeeded; recovery is then silent.)
+
+e) Heartbeat beat (:1043-1053 block): after `writeLiveness();` and `maybeReportMaintenance(ctx);`, add:
+
+```ts
+          // A healthy connection checks too: the beat that just refreshed the
+          // lock is the beat that notices the plane handed us new credentials.
+          // The close is the ordinary non-terminal kind — finish() clears this
+          // very timer, so one change is applied once and redialed once.
+          if (refreshConnectionConfig()) {
+            try {
+              ws.close(1000, "config changed");
+            } catch {
+              /* already closing — the loop redials on the new identity anyway */
+            }
+          }
+```
+
+f) Reconnect loop seam (~:1133), between the provisioning gate and the dial:
+
+```ts
+      await provisioning; // §5: R7's provisioning close must not redial past its own key write
+      // The incident belt: a daemon stuck between dials (refused bearer, dead
+      // plane) has NO heartbeat beat to check on — re-check before every dial.
+      refreshConnectionConfig();
+      const close = await runConnection();
+```
+
+g) Update the `runDaemon` docblock: after "refreshed on every heartbeat tick" add one sentence — "The connection identity hot-reloads from `config.json` on the beat and before every dial (design 2026-10-10 §A); a re-registration lands within one beat without a restart."

+- [ ] **Step 3: Implement the dot + swap it into the row and table**
+

+
+/**

+ * the text chip: a gray chip beside the gray OS chip was invisible, and an
+ * operator watched a dead node that had stopped accepting credentials while a
+ * re-registration sat offline for hours.
+ *
+ * Unlike the rail's dot (aria-hidden: the row text carries the state), this dot
+ * IS the state carrier on this page — the word it once read is now only here,
+ * so it announces itself and shows a title. No blink: a node is not "working".
+ */
+export function NodeStatusDot({ node }: { node: Node }) {
+  const online = node.status === "online";
+  const label = online
+    ? "online"

+}
+```
+
+In `node-row.tsx`: delete the status `Badge` line (`<Badge variant={node.status === "online" ? "success" : "muted"}>{node.status}</Badge>`) and its import of nothing else changes; in the identity column wrap the name line so the dot leads:
+
+```tsx

+        </div>
+```
+
+(add `import { NodeStatusDot } from "@/components/nodes/node-status-dot";` and update the component docblock: "name + status dot" replacing "status badge" in the chip inventory.)
+
+In `node-table.tsx`: replace the status cell's Badge with the dot, keeping the maintenance chip:
+
+```tsx
+      <td className="py-2 pr-4">
+        <div className="flex items-center gap-2">
+          <NodeStatusDot node={node} />

+
+Run: `cd apps/server/web && bun test src/components/nodes/__tests__ src/lib/__tests__/node-filter.test.ts`
+Expected: new tests pass; any pre-existing component test that asserted the `online`/`offline` chip text needs its expectation updated to the dot's aria-label (search first: `grep -rn '"online"\|"offline"\|getByText' src/components/nodes/__tests__ src/routes/__tests__ | grep -i node`) — update assertions, never the component, unless the assertion is genuinely about the chip's existence (it isn't anymore).

+### Task B3: Nodes toolbar — search + status + shared, zero-match state
+
+**Files:**
+- Modify: `apps/server/web/src/routes/nodes.tsx`
+- Create: `apps/server/web/src/routes/__tests__/nodes-page-filters.test.tsx`
+
+**Interfaces:**
+- Consumes: `NODE_FILTERS_OFF`, `filterNodes` (B1), `NodeStatusDot`-bearing rows (B2), `EmptyState`, `Select*` from `@/components/ui/select`, `Input` from `@internal/node-admin` (the `subshell-search.tsx` idiom), `useNodes` fetch stubbing via `setFetchRouter` (see `nodes-page-gate.test.tsx`).
+- Produces: filtered rendering in both views; page state only, no exports.
+
+- [ ] **Step 1: Write the failing test**
+
+Create `apps/server/web/src/routes/__tests__/nodes-page-filters.test.tsx` — copy the ROUTER/FIXTURE scaffolding VERBATIM in shape from `nodes-page-gate.test.tsx` (its QueryClient + memory router + `setFetchRouter` stub of `GET /api/nodes`), with two nodes in the stub list instead of zero/one: `{ id: "n1", name: "AI PC", hostname: "theo-linux-ai", status: "offline", access: "owner", ... }` and `{ id: "n2", name: "Server", hostname: "mac-builder", status: "online", access: "edit", ... }` (all fields the existing gate-test fixture already supplies). Then:
+
+```tsx
+test("search narrows both the tiles and the list; status and access select", async () => {
+  // render at /nodes (tiles default)
+  expect(await screen.findByText("AI PC")).toBeInTheDocument();
+  await user.type(screen.getByRole("searchbox", { name: "Search nodes" }), "server");
+  expect(await screen.findByText("Server")).toBeInTheDocument();
+  expect(screen.queryByText("AI PC")).not.toBeInTheDocument();
+  await user.clear(screen.getByRole("searchbox", { name: "Search nodes" }));
+  // status select (combobox per the ui/select component's role):
+  await user.click(screen.getByRole("combobox", { name: "Filter by status" }));
+  await user.click(await screen.findByRole("option", { name: "Offline" }));
+  expect(await screen.findByText("AI PC")).toBeInTheDocument();
+  expect(screen.queryByText("Server")).not.toBeInTheDocument();

+
+test("zero matches offers Clear filters, distinct from the enrollment empty state", async () => {

+  await user.click(screen.getByRole("button", { name: "Clear filters" }));
+  expect(await screen.findByText("AI PC")).toBeInTheDocument();
+});
+```
+
+(`user` is `userEvent` as set up in the gate test — mirror its exact import; if `toBeInTheDocument` isn't available in this repo's bun:test env, assert on `.textContent` / truthiness exactly as the gate test does.)
+
+- [ ] **Step 2: Run to verify it fails** (no searchbox/combobox roles exist).
+
+Run: `cd apps/server/web && bun test src/routes/__tests__/nodes-page-filters.test.tsx`
+
+- [ ] **Step 3: Implement the toolbar in `nodes.tsx`**
+
+Add imports (`Input` from `@internal/node-admin`; `Select, SelectContent, SelectItem, SelectTrigger, SelectValue` from `@/components/ui/select`; `NODE_FILTERS_OFF, type NodeFilters, filterNodes` from `@/lib/node-filter`). In `NodesPage`:
+
+```tsx
+  // Page state, not URL — the home page's machine-filter precedent: filters
+  // narrow BOTH list views and a back button is expected to leave them alone
+  // (the view tab keeps the URL). (design 2026-10-10 §B)
+  const [filters, setFilters] = useState<NodeFilters>(NODE_FILTERS_OFF);
+  const visible = filterNodes(nodes, filters);
+```
+
+Render the toolbar between the `Segmented` and the keys/list branch, shown ONLY when the current view has data to narrow:
+
+```tsx
+          {active !== "keys" && nodes.length > 0 && (
+          <div className="flex flex-wrap items-center gap-2">
+            <Input
+              value={filters.query}
+              onChange={(e) => setFilters((f) => ({ ...f, query: e.target.value }))}
+              placeholder="Search by name or hostname…"
+              aria-label="Search nodes"
+              className="max-w-sm"
+            />
+            <Select value={filters.status} onValueChange={(v) => setFilters((f) => ({ ...f, status: v as NodeFilters["status"] }))}>
+              <SelectTrigger aria-label="Filter by status" className="w-36">
+                <SelectValue />

+              <SelectContent>
+                <SelectItem value="all">All status</SelectItem>
+                <SelectItem value="online">Online</SelectItem>
+                <SelectItem value="offline">Offline</SelectItem>
+              </SelectContent>
+            </Select>
+            <Select value={filters.access} onValueChange={(v) => setFilters((f) => ({ ...f, access: v as NodeFilters["access"] }))}>
+              <SelectTrigger aria-label="Filter by access" className="w-32">
+                <SelectValue />
+              </SelectTrigger>
+              <SelectContent>
+                <SelectItem value="all">All access</SelectItem>
+                <SelectItem value="yours">Yours</SelectItem>
+                <SelectItem value="shared">Shared</SelectItem>
+              </SelectContent>
+            </Select>
+          </div>
+```
+
+(The `Select` controlled-prop API is whatever `components/ui/select.tsx` actually exposes — mirror how `routes/index.tsx` wires its machine filter; adjust `onValueChange` to the component's real prop name before committing.)
+
+Swap the render branch from `nodes` to `visible`, and add the zero-match state (distinct from `No nodes yet`):
+
+```tsx
+          {nodes.length > 0 && visible.length === 0 && (
+            <EmptyState
+              icon={Server}
+              title="No nodes match"
+              description="No node matches the current search and filters."
+              actionLabel="Clear filters"
+              onAction={() => setFilters(NODE_FILTERS_OFF)}
+            />
+          )}
+          {visible.length > 0 &&
+            (active === "list" ? <NodeTable nodes={visible} …same props… /> : <div className="space-y-3">{visible.map(…)}</div>)}
+```
+
+The existing `nodes.length === 0` enrollment EmptyState stays exactly as is — the two states answer different questions.
+
+- [ ] **Step 4: Run the route tests green**
+
+Run: `cd apps/server/web && bun test src/routes/__tests__/nodes-page-filters.test.tsx src/routes/__tests__/nodes-page-gate.test.tsx`
+Expected: both files pass (the gate test proves the enrollment states survived).
+
+- [ ] **Step 5: Full-web regression + commit**
+
+```bash
+cd apps/server/web && bun test src/components/nodes src/lib/__tests__ src/routes/__tests__
+git add apps/server/web/src/routes/nodes.tsx apps/server/web/src/routes/__tests__/nodes-page-filters.test.tsx

+
+```bash
+cd apps/node/agent && bun test src/__tests__/daemon.test.ts src/__tests__/config-connection.test.ts
+cd apps/server/web && bun test src

+
+Expected: green. Then push the branch and open ONE PR covering the spec's two parts (independent commits make review separable): `git push -u origin fix/node-reregister-and-filters`.

+**Non-vacuous before flip:** every test that rewrites the config while a socket is live must FIRST wait for the connection to be established (the file's established-socket idiom — e.g. `await waitFor<NodeEvent>(h, (e) => e.type === "heartbeat")`, or mirror how adjacent tests wait for `ready`). A beat can only fire on an established socket; a test that flips the file before the daemon ever connected asserts nothing.

Subject: [PATCH 12/44] fix(node): the swap gate refuses an un-dialable target;
 own writes stop reading as foreign
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review round 1 of PR #359 (quote-verified):
- MAJOR: the hot-reload gate validated only the pinned key before swapping, but
  loadConfig proves fields are STRINGS, not that they open a socket. A beat that
  swapped in a parseable-but-un-dialable serverUrl ("not a url", "", a junk
  nodeWsUrl) dropped the healthy connection, and the WebSocket constructor's
  throw has no catch between the dial and process exit (runConnection reject ->
  the loop -> runDaemon -> cli) — the service respawned into the same death,
  inverting the seam's stated worst-case-is-status-quo for exactly the writer
  that motivated it. The gate now validates the whole-bundle DIAL TARGET
  (parseable, ws:/wss:) beside the pin, deduped through the same warn; the
  refusal is not sticky (next legitimate write reconnects). Belt for the
  loop's missing catch was considered and left out on purpose: the gate closes
  the real entry, and a loop-catch changes the unwind paths the tests pin.
- MINOR m1: persistLink mirrors its own §5 heal onto the live config but not
  onto liveIdentity, so every legacy self-heal logged a false "config changed;
  reconnecting" line at the loop seam (and correctness rode on R7's close
  ordering). The mirror now advances the tracker with it.
- NIT n1 (same seam): a stale concurrent reader (beat in flight while the
  loop seam swapped) could have re-applied the superseded bundle for a beat;
  the reader now yields when the identity moved under its read.

Tests: red on pre-fix, green on fix — the new un-dialable-serverUrl case and
test (c)'s new false-line assertion; suite 913/913, biome + verify-types clean.

Subject: [PATCH 13/44] fix(copy): use consistent, conversational language
 across Subshell (#360)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* docs(style): agent means the AI agent, and status copy writes from the reader's seat

The operator ruled (2026-10-10) that 'agent' confuses users when it names the
node's background program: the daemon is the daemon (or node daemon), and a
space-tight column header reads Version. STYLE.md gains the Daemon/Agent
glossary rows, the ban on 'node agent' and an 'Agent' column for the daemon,
and a new Status and problem sentences section: name what is true of the
reader's machine, then the action that remains; no protocol verbs, no
possessive riddles. The worked pair is the held-node line, before and after.
.claude/rules/design-system.md carries the two-line pointer so UI agents see
the ruling without opening the guide.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(copy): the node daemon is the daemon, everywhere a person reads it

The word 'agent' now means only the AI agent a pane drives (ruling
2026-10-10, doctrine committed last commit). This applies it:

- SPA: the Nodes table's Agent column becomes Version (the detail page
  already said Node version); the update card says the daemon restarts
  itself, and the held-node line becomes the operator-approved sentence
  'The server will not accept this machine's Subshell daemon version.
  You can still update it from here.' replacing the refuse-its-agent
  original.
- Node CLI, setup questions, probe warnings, update refusals, the
  4406 exit line, maintenance/service/reset/env-forced messages: daemon,
  with the reader-seat rewrite where the old text described what the
  protocol layer did. 'KICKS' prose becomes 'disconnects'.
- The daemon's own log file becomes logs/daemon.log. No migration: the
  plane's agent_log_read, the loopback dashboard, status --json, reset,
  and the desktop app's reveal-a-log ladder all fall back to agent.log
  until the daemon has written under the new name; tests pin the ladder
  on both the node and desktop side. Wire field names (agentLog,
  agentLogPath, agentVersion, kind 'agent') are identifiers and stay.
- Desktop: app descriptions, the downgrade refusal, and the no-log hint.
- docs: paths.mdx and security.md name the daemon log (and the quoted
  Nodes-dialog string is corrected to the label the dialog actually
  shows); node agent in-repo docs follow the file rename.

Kept per the ruling: 'launchd agent' (Apple's term for server
supervision) and every AI-meaning agent (Add an Agent, the harness card,
Send prompt to agent?). Full suites green: node 905, server 3953, rust
fmt/clippy/test, design tokens, prose.

Co-Authored-By: Claude <noreply@anthropic.com>

* test(cli-e2e): the reset scenario seeds and names daemon.log

The bun suite stubs every service seam, so the renamed log file and the
reworded reset line land invisible to it; the compiled scenario is the thing
that drives the real binary. It seeded logs/agent.log and grepped 'left the
agent', both of which this branch renames.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(web): 'node you can't see' reveals nothing more on hover

The rail header (and the home tiles) carried the invisible node's full id
as tooltip text, a kept-over reveal from the retired node pill whose point
was telling machines apart. An operator, shown the uuid, asked the obvious
question: if you can't see it, why is it shown? An id with no page behind
it names nothing to act on; title now equals label, and both consumers'
equal-title branch renders no tooltip. The cold arm keeps its reveal (a
short id becoming the full one) because there the machine IS the reader's,
merely not loaded yet.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(copy): the review round's findings — transfer lines, re-register refusal, OpenAPI prose

Four minor, four nit, all quote-verified: the transfer refusals named the
daemon 'the agent on node X' (the double meaning this PR exists to kill,
sharpest where a harness reads the sentence about itself); the re-register
refusal told the wizard's reader a row 'cannot re-register as an agent';
node-assistant.md still named agent.log as the first rung; the 4409 line
said 'another subshell' for a daemon; the rollback lines kept the verb
'refused' the new STYLE section bans in status prose; 'agent node' in
shipped OpenAPI descriptions reads as the AI sense. The readable-path
docblock now names the one accepted switchover cost (a held poll offset the
startup burst outgrows between polls skips bytes until a reload), and the
Rust ladder test now also pins legacy-before-manager ordering.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(copy): the second round's findings — the rollback line, the MCP wrap, the schema twins

All quote-verified. The successful-rollback log line still said 'the
control plane refused' where its two failure siblings became 'would not
accept'; the MCP wrap around the transfer-too-old error said 'the agent on
the target node' three times around the (already fixed) interpolated
server sentence; the transfer tool's own z.string description was the
schema twin of the OpenAPI line round one renamed; three comments still
promised the hover reveal the tooltip ruling removed; the 4406 tail asked
for 'a newer subshell'; the restart fallback note kept 'refused'; the
cli-e2e step title kept the old word beside its renamed log file; and the
desktop package.json line this PR edited still shipped an em dash.

The rollback line now has a test pin (daemon.test.ts, 4406 revert path):
'would not accept 9.9.9' present, 'the control plane refused' absent. The
4406 fixture strings now quote the server's real phrasing ('this node is').

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(changeset): the two SPA entries name @internal/server

@internal/server-web is on changesets' ignore list; the SPA ships embedded
in the server binary, and every prior SPA-only changeset (#356's stale-
detection entry among them) names @internal/server. An ignored key here
would ride NO release.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(copy): the third round's findings — the no-reason fallback and the dashboard verbs

The 4406 revert fallback recorded 'the control plane refused it' into
update-failed.json, which the loopback dashboard prints raw and which the
rewritten rollback line interpolated — 'no reason was given' now, with a
test that closes 4406 WITHOUT a reason and pins both the record and the
log line. The dashboard's three error fallbacks ('The update was refused'
et al) became plain outcomes, matching the update.ts note round two fixed.
The log-file test restores the preload's config home instead of deleting
the variable, so a test added below it cannot resolve the developer's real
~/.config/subshell.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(copy): the fourth round's findings — transfer_nodes' own description

The MCP tool's shipped description told harnesses (and the humans reading
them) that transfers run 'between two AGENT nodes', and one HTTP refusal
in the same route family said it plainly - while the refusal it quotes
about itself now says 'the daemon'. Both re-worded to machine nodes; the
route's own docblock follows its text.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(copy): the fifth round's findings — the broken pin, the docs twins, and three strays

The transfer-route test pinned toContain('agent nodes'), a shorter
fragment than the message the last commit re-worded: it failed the moment
that shipped (9/9 now, on 'machine nodes'). The public MCP tools page
duplicated the server description's two sentences verbatim, so it moved
with them. Three OpenAPI prose sites join the swept class ('an agent
node' -> 'a machine node', 'an enrolled agent' -> 'an enrolled machine
node', per the models.ts and reregister precedent this PR set). The
Subshell Server app's reset confirmation - the app no sweep had visited -
says 'a node agent on this machine keep running'; that is the node
daemon. And the dashboard's maxBytes schema line says agent log beside a
file this PR renamed.

Co-Authored-By: Claude <noreply@anthropic.com>

* chore(changeset): the Server app's reset dialog rides desktop-server

The reset confirmation that gained 'node daemon' renders inside Subshell
Server's window; no entry named @internal/desktop-server, so the app would
have carried a wording change with no version.

Co-Authored-By: Claude <noreply@anthropic.com>

* style(rust): the two test edits in the shapes CI's rustfmt wants

cargo fmt --check on the runner re-wrapped an assert_eq! into one line and
re-split an assert! into three; the local toolchain accepted both prior
shapes, so rust:check stayed green while CI's fmt gate saw the diff. Content
unchanged - wrapping only.

* fix(copy): apply conversational style across product and docs

* test(e2e): follow fixed copy and selected setup addresses

+The node's own log file is `logs/daemon.log` where it was `logs/agent.log`, the name matching the word. Nothing migrates the file: every reader (the plane's log view, the machine's loopback dashboard, `subshell status`, reset, the desktop app) falls back to the old name until the daemon has written the new one, so an upgraded node shows its history from the first poll rather than after its first line.

+The word "agent" now means the AI agent a subshell pane drives, and nothing else. The node's background program is the **daemon** (or node daemon), everywhere a person reads about it: the Nodes table's `Agent` column is **Version**, the update card says the daemon restarts itself, a refused version reads "The server will not accept this machine's Subshell daemon version. You can still update it from here.", `subshell setup` asks "Run the Subshell daemon in the background and start it at login?", and the daemon's own refusal lines, probe warnings, update errors and both desktop apps' descriptions and reset confirmations say daemon too. Status sentences were rewritten from the reader's seat: what is true of their machine, then what they can still do, with no protocol verbs. The rule and its worked example live in `apps/docs/STYLE.md`.

Owner-only (admin on `local`): the re-share gate `canManage`, NOT `nodeCanConfigure` and NOT the wider `canRetire` gate delete/re-register sit on; the machine's own `subshell maintenance on|off` sets the same flag; newer stamp wins, ties to the plane, so the node's mirror check is defence in depth, not a second switch. Containment is deleting the node, rotating its key, or clearing shares, all cookie-gated. Audited.
 - **Service control** (signed command; cookie only, owner or `edit`, `local` refused, audited `{verb, forced}`): the agent refuses unless the manager reports this very pid, and when the definition would take its panes down without `force`; **`stop`/`uninstall` are owner-only and structurally one-way** (they end the socket that would carry the undo); `force` is refused outright on `start`/`install`.
 - **Repointing** (signed `set_server_url`) is **owner-only and a real widening**: the machine dials the named host with the node key, valid on THIS plane; loopback refused outright; addresses validated by component, stored canonicalized; audited naming the NEW value only; takes effect next start.
-- **Disclosure surfaces:** the runtime report (supervision, paths, tmux) attaches only for an ONLINE agent node, viewer owner or `edit`, never `local`, never `view`. `ready` discloses host facts (agentVersion, os/arch, hostname, dataDir, capabilities, selfInvoke prefix, homeDir); `detect` answers ONLY the binaries/env names the plane asked (union of `subshell.hostEnv` across enabled manifests), never scans, so a plugin install (admin) decides what env names every node may be asked. `held` is disclosed to every viewer; `runtime` is not.

 - **Refused agents are HELD, not closed** (§11.12): offline for every purpose but `update` (frames dropped after envelope parse, before dispatch); the `update` command's wire shape is FROZEN across protocol bumps for this.
 - **Re-registration keys**: cookie retire-gated (owner or any admin, `canRetire`) on agent nodes; the mint is stored under the node's owner so redemption's ownership check holds; `POST /api/nodes/:id/reregister` mints a single-use 24 h setup key bound to the existing row. Redemption through enroll preserves node relationships and settings, atomically swaps credentials and public identities, revokes the old bearer and unused sibling recovery keys, and evicts live/held links. Minting disconnects nothing. Deleting the target cascades recovery keys. Recovery adds no row, so `allow_node_enrollment` gates only new-node keys. Audits `node.reregister_key|reregister` carry ids, never secrets.
 - **Setup keys**: single-use, 24 h, plaintext-stored to the key's OWNER only (the future node owner; for an admin-minted recovery key that is the node's owner, not the admin who triggered the mint) (cookie-only; a machine token 403s the list); `setup_key.create` carries no metadata: the key text never enters the trail. Admin may revoke ANY row (`setup_key.revoke`, `{foreign: true}` metadata), `?all=1` is admin-only (deliberate 403, never a silently-narrowed list). The node names itself (`--name`, `SUBSHELL_NODE_NAME`; `enroll` requires it) via `normalizeNodeName`, the same rule rename applies; a RECOVERY redemption validates the supplied name but does not apply it, the existing row keeps its own. Minting is gated by `allow_node_enrollment` (absent = TRUE; enforced at the mint ONLY (the key IS the credential); bounds the future, never revokes what is outstanding). `GET /install.sh` renders identically for absent/unknown/spent/expired keys (never a binary oracle); a VALID key bound to an existing node additionally names the node it re-registers and pre-supplies the wizard's name answer (the recovery path ignores any name; the row keeps its own), which discriminates between two LIVE keys only, and either one's holder can already redeem to control the node; enroll answers three distinct 401s by design. The key rides the install URL → shell history and access logs: the accepted posture of enrollment links.
 - **Agent artifacts are never anonymous**: cookie, or valid unconsumed setup key, or one-time `?update_token=` (unlocks exactly one file at one digest; never reaches the `.sha256` routes). `install.sh`'s `server=<origin>` must be exact membership of the live trusted-origin registry; the rendered script digest-verifies before the first `chmod +x`.
 - **Lazy release fetch**: every release-source fetch passes `releaseFetchAllowed` (configured origin ∪ GitHub release hosts; refused **by name before any connection**, egress destination pinned); no binary bytes until a machine is served (since 2026-10-09 the tiny index/manifest reads behind the serve decision run per authenticated download, TTL-cached with a one-minute failure backoff); hashed against the digest from the **signed manifest's `assets` map** (sidecar never fetched); bounded by `MAX_ARTIFACT_BYTES` (300 MB); only manifests declaring THIS `NODE_PROTOCOL_VERSION` are offered; only files this instance fetched (`.fetched.json`) are ever superseded or deleted; the shelf is reconciled AT SERVE TIME (2026-10-09: the copy is run `<file> version`, the newest server-supportable build wins, a hand-published copy speaking this protocol with a higher semver stays truth, a wrong-protocol copy 404s instead of installing a never-connectable agent, and `.sha256` announces the SAME decision the installer's skip depends on), an update download is served release-coherently else 409 naming the remedy. Empty `SUBSHELL_RELEASE_URL` = air-gapped (the shelf is the only source and answers for itself the same way: connectable and self-consistent, or refused).
 - **CLI-side**: `subshell configure --server` is unprivileged, non-destructive, one-plane-two-names. It does disclose the node key to the host named (treat it as naming a host you trust). `configure --key` refuses an `nsk_` setup key by name. Re-enrolling in Subshell Client IS confirmation-gated (it overwrites `config.json` and discards the old node key).
-- **The node's loopback dashboard** (§6): 127.0.0.1:3090 with **no login by design**: the listen address plus the OS user IS the access control (`Host` loopback; `Origin` when present loopback; mutations need `content-type: application/json`).

+## Writing voice
+
+Write code comments, app copy (including CLI output), website text, and public
+documentation in fluid, natural, conversational English, as if you're speaking
+to a peer. Use active voice and familiar words. Use contractions like "don't"
+and "it's" where they sound natural. Vary sentence length and structure, and
+connect related ideas so the prose flows. Avoid textbook formality, stock AI
+phrases, repetitive sentence patterns, and robotic summaries or conclusions.
+
+In app messages, including backend errors shown in the UI or returned by the
+API, explain what's happening and give a useful next step when one exists.
+Keep error codes, HTTP statuses, and diagnostic fields stable when editing
+messages. Don't expose internal details or promise that retrying is safe when
+the operation may already have changed something.
+In comments, explain the reason, constraint, or surprising behavior a
+maintainer needs to understand. Keep technical terms where they add precision,
+and preserve warnings, conditions, identifiers, and quoted output accurately.
+Read the result aloud: it should sound like something you'd say to a colleague.
+
+Use "subshell" for UI objects and actions. When introducing the term in
+documentation, explain that a subshell is a terminal session running an agent
+or a shell. "Session" is fine in explanations once that relationship is clear.
+
+Keep UI titles short and fixed. Name the action, such as "Close this subshell?"
+or "Generate a new setup key?", and put names, counts, versions, addresses,
+and other variable details in the body. This applies to dialogs, confirmations,
+cards, and action headings; it doesn't prevent an object list from showing its
+names. A name-length limit isn't an exception, and historical specs don't
+override this rule.
+
+Describe the action the control actually takes. Inserting a prompt doesn't
+submit it; generating a setup key doesn't re-register the node yet. Explain
+when a consequence happens, what it affects, and whether it can be undone.
+Distinguish an attempt from a guarantee, and interruption from permanent loss.
+Keep necessary warnings visible at the decision point. Aim for one or two
+short sentences, but use more when clarity or consequences require it.
+
+Keep labels, tooltips, notifications, and guides consistent. Include only
+details useful in that context: a tooltip defining a sidebar group doesn't

 ## Project Overview
 
 This is a **Bun-powered TypeScript monorepo** using Turborepo for orchestration. It contains an ElysiaJS API server, the React SPA that server serves, a node daemon (`subshell`), two Tauri desktop apps, a React Native companion, and shared packages: a type-safe Eden Treaty client SDK, the subshell protocol, agent harness plugins, a shared `subshell mcp` server, and backend error handling.

 moment the list could hold more than one plane, because neither item said

+## Product copy and confirmations
+
+Use the same voice across the app, website, CLI, backend errors, notifications,
+MCP descriptions, package READMEs, and code comments. Write for what the reader
+needs to understand or do at that moment. Keep technical detail when it helps
+them decide; leave implementation mechanics to developer-facing content.
+
+Keep titles short and fixed. Put names, counts, versions, addresses, and
+other variable details in the body, where they can wrap without overwhelming
+the heading. This applies to dialogs, confirmations, cards, and action
+headings, not the names displayed in object lists. Neither a name-length cap
+nor an old specification is an exception.
+
+A confirmation names the immediate action, identifies its target in the body,
+and explains its consequences. Make timing clear: generating a setup key is
+a different step from using it. Keep deletion, access, and trust warnings
+visible before the reader acts. Say "tries to stop" when stopping can fail.
+Say "interrupts" when work is interrupted; reserve "permanently deletes" for
+data that is actually deleted. Don't promise that an agent will resume a
+conversation when that depends on its saved history.
+
+Prefer explicit button labels such as "Insert prompt", "Close subshell",
+"Revoke key", and "Remove key". Use the same term in the menu, confirmation,
+accessible label, and guide. An insertion that doesn't press Enter isn't
+"Send". A used or expired key is removed from the list; a usable key is revoked.
+
+Aim for one or two short sentences, not a rigid sentence limit. Add a sentence
+when it makes consequences or conditions easier to understand. Don't compress
+warnings into run-ons or move essential information behind a disclosure.
+Tooltips should answer the local question: "Subshells opened by another
+subshell" defines the sidebar group without explaining its notification policy.
+
+These examples illustrate the preferred style. They aren't proof that every
+surface already uses the wording; verify the implementation when quoting UI.
+
+| Context | Preferred wording |
+| --- | --- |
+| Prompt insertion | **Insert this prompt?** This adds the prompt to the subshell without submitting it. Review it there, then press Enter when you're ready. |
+| Prompt stack | **New prompt stack**. Combine saved prompts and custom instructions into one prompt. |
+| Attention notification | Waiting for you |
+| Completed-turn notification | Ready for your next message |
+| Closing a subshell | **Close this subshell?** This stops the process and permanently deletes "Build agent" and its history. You can't undo this. |
+| Maintenance | Maintenance blocks new subshells on this machine for everyone and tries to stop existing ones. Some may keep running if they can't be stopped. Subshells that stop won't restart automatically when maintenance ends. |
+| Expired setup key | This key has expired. Removing it clears it from the list without affecting any connected machines. |
+
+Use "subshell" for UI objects and actions. Introduce it as a terminal session
+running an agent or a shell; "session" is fine in explanatory prose after that.
+
+## Content review workflow
+
+Apply routine improvements autonomously within the requested scope. Fix stiff
+phrasing, unclear action labels, inconsistent terminology, and unnecessary
+detail using this guide. Don't ask the user to choose between equivalent
+sentences when the intended meaning is clear.
+
+1. Read the current copy in context and verify the behavior it describes.
+   Check the surrounding screen or procedure, permissions, timing, and failure
+   cases. A wording choice can't resolve an unknown implementation fact.
+2. Make routine edits directly. Ask only when the wording would decide product
+   meaning, an ambiguous term, behavior, or marketing positioning. Continue
+   independent edits while that question is pending.
+3. When asking, show the full current text and complete alternatives. For a
+   dialog, include its title, description, and button labels; for a
+   notification, include the relevant title and body. Explain the difference
+   briefly, recommend an option, and label choices so the user can answer
+   easily. Use clearly identified example names in place of variable values.
+   Keep each batch small enough to compare.
+4. Treat the user's choices and refinements as continuing guidance. Apply them
+   to equivalent cases without asking again. Carry approved wording through
+   related menus, dialogs, tooltips, accessibility labels, public guides, and
+   existing test expectations. Preserve error codes, statuses, identifiers,
+   and behavior when the task is copy editing.
+5. Update this guide when a decision establishes a reusable rule, and remove
+   conflicting guidance from current documentation. Keep historical specs as
+   history rather than rewriting them to describe today's preference.
+6. Review the resulting copy in context and run the relevant repository checks.
+   Report what changed and any verification limits. Don't manufacture more
+   choices to prolong a review; say when no further product decisions need
+   the user's attention.
+
+## Status messages and comments
+
+In app copy and documentation, say what's happening in terms the reader can
+use. Give a next step when one exists, and keep the message short enough to
+read at a glance. Use pronouns when their meaning is clear; name the machine,
+session, or program when it isn't. Don't invent a remedy to complete a formula.
+
+These examples show how to make copy more natural without losing its meaning:
+
+| Before | After |
+| --- | --- |
+| “The server will not accept this machine's Subshell daemon version. You can still update it from here.” | “The server doesn't support this machine's Subshell daemon version. You can still update it from here.” |
+| “The update did not run.” | “The update didn't run.” |
+| “left the daemon's own log at PATH: the record of this act, and no credential in it” | “Kept the daemon log at PATH. It records this reset and contains no credentials.” |
+| “re-running it is the retry” | “Run the transfer again to retry.” |
+
+Code comments use the same voice for a different reader: another developer.
+Explain why the code works this way, including constraints and edge cases.
+Keep precise protocol terms where they help. For example, write “Fall back to
+agent.log until the daemon writes its first log under the new name.” There's
+no need to recount the copy review that prompted the rename. Avoid all-caps
+emphasis and metaphors such as “the ladder's third arm” when you mean a
+fallback branch.
+
+Examples aren't replacement text for quoted output. Verify the actual behavior
+and update any matching UI, tests, or quotations together when changing a message.

 ## Network and WebSocket protection
 
 The server listens on all interfaces by default. Network reachability and permission to sign in are separate controls. Firewall rules and your private network determine who can reach the port; Subshell authentication and resource permissions determine what an admitted caller can do.
 
-Browser origins are checked against a registry derived from the server's configured addresses, its LAN interface addresses on a wildcard bind, administrator-supplied extra origins, and enabled network plugins. The registry does not trust an arbitrary requesting hostname. Configuration controls reject new wildcard origin entries. This limits cross-origin requests and DNS-rebinding attacks, but an origin allowlist is not a firewall or protection against a non-browser client.

 WebSocket attachment tokens expire after 30 seconds and can be redeemed once. Bearer-minted tokens are bound to one session; a pane token can mint one only for its own session. The dashboard feed refuses these session-bound tokens. Same-host attachment can also authenticate with the browser session cookie, so not every WebSocket connection uses an attachment token.

A broken encrypted stream fails the connection rather than continuing with plaintext. This protects node traffic even when its WebSocket transport isn't TLS.
 
 Commands also carry **ES256 signed envelopes**. Each envelope names one target node, expires after 30 seconds, and has a single-use identifier checked against replay. A node verifies the signature, target, and freshness before executing a command. Encryption protects confidentiality; signing limits who can authorize work and where a command can run.

Encryption after pairing does not independently prove that the first server was the one you intended. Use a trusted enrollment path and address.

 Neither encryption nor signing protects a node from a compromised server that holds the signing keys.

 ## Restart a session
 
 When a process exits, the subshell may remain listed with `status: "running"` and `alive: false`. In the server dashboard's sidebar, choose **Subshells**, open the session's **⋯** menu, and choose **Restart** to revive it in place. A terminated subshell offers **Start again**.

A `timed_out` answer is a success: nothing further is sent, and `output` carries what printed so far, which can end mid-line. `output` holds the newest lines inside 256 KiB (`truncated` names the drop) and includes the shell's echo of the typed command. `nextByte` is the raw log offset just past the sentinel line, or where the wait stopped; pass it as `read_subshell_log`'s `from_byte` to continue exactly.

A timeout doesn't prove that the node performed no work; inspect state before retrying an operation that could create or change something.
 
 A command that runs for minutes is queued behind every other command on that node's serialized connection: while a node builds or extracts an archive, its pane input waits its turn. Transfers are bounded so the wait stays finite: relay windows are capped at 512 KiB of raw bytes per frame, and one archive at 4 GiB uncompressed.

-The node's own log file is `logs/daemon.log` where it was `logs/agent.log`, the name matching the word. Nothing migrates the file: every reader (the plane's log view, the machine's loopback dashboard, `subshell status`, reset, the desktop app) falls back to the old name until the daemon has written the new one, so an upgraded node shows its history from the first poll rather than after its first line.

-The word "agent" now means the AI agent a subshell pane drives, and nothing else. The node's background program is the **daemon** (or node daemon), everywhere a person reads about it: the Nodes table's `Agent` column is **Version**, the update card says the daemon restarts itself, a refused version reads "The server will not accept this machine's Subshell daemon version. You can still update it from here.", `subshell setup` asks "Run the Subshell daemon in the background and start it at login?", and the daemon's own refusal lines, probe warnings, update errors and both desktop apps' descriptions and reset confirmations say daemon too. Status sentences were rewritten from the reader's seat: what is true of their machine, then what they can still do, with no protocol verbs. The rule and its worked example live in `apps/docs/STYLE.md`.

-A sidebar group headed "node you can't see" no longer spells that machine's full id on hover. The id was a leftover reveal from the retired node pill, meant for telling machines apart; for a node the registry has already refused to name it discloses nothing a reader can act on (ruling 2026-10-10). A cold registry still reveals the full id under a short one, because there the machine is the reader's own, merely not loaded yet.

You can still update it from here.", `subshell setup` asks "Run the Subshell daemon in the background and start it at login?", and the daemon's own refusal lines, probe warnings, update errors and both desktop apps' descriptions and reset confirmations say daemon too. Status sentences were rewritten from the reader's seat: what is true of their machine, then what they can still do, with no protocol verbs. The rule and its worked example live in `apps/docs/STYLE.md`.

The id was a leftover reveal from the retired node pill, meant for telling machines apart; for a node the registry has already refused to name it discloses nothing a reader can act on (ruling 2026-10-10). A cold registry still reveals the full id under a short one, because there the machine is the reader's own, merely not loaded yet.

Subject: [PATCH 38/44] Explain disabled controls across the app (#370)

* Explain disabled controls across the app

* fix: show update progress immediately and highlight service restrictions

* fix: address disabled-control review findings

* fix: address second review pass on disabled controls

Spell e-mail in the mobile sign-in reason, and neutralize the devices-strip
note that accused a still-loading entry of view-only access. Narrow the
design guide's Help text rule to inline explanations so the tooltip popup
amendment stops contradicting it, and mirror the split in the loaded rules
summary. Document the tooltip-latch remount tradeoff in all three button
copies, and drop the blocker paragraph's now-unreferenced id.

+Explain why disabled buttons are unavailable on hover, keyboard focus, or touch. Highlight owner-only restrictions and service prerequisites in gold, and use form validation messages to explain missing input.

+Show status as soon as server and node updates start, and fetch node progress while the update request is pending. Keep progress gold until completion is confirmed, and hide the previous attempt's result when a new update starts.
+
+Avoid mounting tooltips for controls without an explanation, preserve focus when an explanation clears, and show the specific maintenance restriction in the mobile node picker.

 # @internal/desktop-server
 
+## 1.4.11
+
+### Patch Changes
+
+- [#370](https://github.com/subshell-ai/subshell/pull/370) [`9352359`](https://github.com/subshell-ai/subshell/commit/93523591dba1812afa69730848aed7d7261d00fd) Thanks [@theogravity](https://github.com/theogravity)! - Explain why disabled buttons are unavailable on hover, keyboard focus, or touch. Highlight owner-only restrictions and service prerequisites in gold, and use form validation messages to explain missing input.
+  
+  Show status as soon as server and node updates start, and fetch node progress while the update request is pending. Keep progress gold until completion is confirmed, and hide the previous attempt's result when a new update starts.
+  
+  Avoid mounting tooltips for controls without an explanation, preserve focus when an explanation clears, and show the specific maintenance restriction in the mobile node picker.
+- Updated dependencies [[`9352359`](https://github.com/subshell-ai/subshell/commit/93523591dba1812afa69730848aed7d7261d00fd)]:

+## Dashboard pages and tables
+
+These are the dashboard decisions established on 2026-10-11. They apply to
+new pages and changes to existing pages; dated design proposals do not override
+this guide.
+
+### Page layout
+
+Use `DashboardPage` for lists, details, personal settings, and server settings,
+including their loading and error states. It fills the available content width
+with 24px outer padding and 24px between sections. Keep those gutters consistent
+as the screen grows; do not impose a narrow maximum width on the page or choose
+a different width for each route. Tables should gain useful space on wide
+screens while still fitting phones.
+
+Terminal and workspace canvases retain their full-height layouts. Standalone
+sign-in and setup screens retain their own frames. A workflow brought into the
+dashboard uses the dashboard layout: Backups uses ordinary settings cards,
+content-sized Backup/Restore tabs, and actions in the card footer. Do not reuse
+the desktop assistant's oversized centered heading or viewport-bottom action
+bar inside a dashboard page.
+
+### Card structure and grouping
+
+Every table belongs in the shared `Card`, including a table built with CSS
+grid. A containing page card counts; do not nest a second card around its table.
+Use the same card header, content spacing, borders, and background across
+Nodes, Presets, Prompts, Subshells, Users, and other tabular pages.
+
+When a list is grouped, give each group its own titled card and table. Presets
+group by agent; the Subshells table uses its selected grouping. Object group
+names may appear as card titles because they identify the listed objects.
+Avoid full-width shaded group bands inside the table or a special striped row
+style for Subshells. Without grouping, use one card.
+
+Presets, prompts, and prompt stacks use tables. Nodes uses a table without a
+tile-view toggle. Subshells can retain its other views; its table follows the
+same rules as every other table.
+
+### Type, density, and alignment
+
+Table headings and values use normal body size (`text-sm` in the SPA).
+Headings and primary name links use `font-strong`; ordinary values remain
+regular. Use sentence-case column headings. Hostnames, versions, timestamps,
+and other secondary values use muted colour, not a smaller font.
+
+Use `h-8 py-0` for ordinary cells, aiming for compact 32px rows. Check the
+height of the controls inside each cell too: a tall name button or menu trigger
+can undo zero cell padding. Let wrapped content, expanded details, and touch
+target requirements increase height when necessary; do not shrink the text.
+
+Header and row selection checkboxes share one column width, horizontal inset,
+and vertical alignment. A group's select-all checkbox selects only that
+group's rows and preserves selections in other groups. It shows checked or
+indeterminate state from that group's actual selection.
+
+### Responsive columns
+
+Use the card's available width, through container queries, to choose which
+columns fit. Keep the name and row actions visible. Hide secondary metadata
+progressively on small screens, and reveal it again as the card widens. Match
+every header's visibility to its cells. For users, an email can move beneath
+the name when its column is hidden; management actions must remain reachable.
+
+When metadata columns are visible, give the name roughly one third of the
+table instead of letting it consume all remaining space. Fit the actions
+column to its controls. Truncate long names and metadata rather than letting
+them push the page wider; make the complete value available through the
+appropriate detail or disclosure. Keep any necessary horizontal scrolling
+inside the card, never on the whole page.
+
+### Values and interactions
+
+Give independent behaviours separate columns. Presets show Auto-restart and
+Cross-agent use separately. Boolean values, including sharing, use **Yes** or
+**No** consistently. Show plain text for provider, role, permissions, and
+routine states, following the field-value rule below; do not turn them into
+badges. Use an absence mark when a value does not apply: the server's local
+node has no remote heartbeat, so its Seen cell must not claim "never".
+
+Clicking a name inspects the item. Node and subshell names link to their detail
+pages. Preset names expand their commands; prompt names expand their text;
+prompt-stack names expand their members. Use a consistent name button and
+chevron for disclosures, with `aria-expanded` and an associated content region.
+Expanded table content stays in a detail row spanning the columns. Edit stays
+in the action menu. Command copying uses the shared copy affordance.
+
+Row action menus and context menus put destructive actions last, after one
+divider when ordinary actions precede them. Restart and Close belong in that
+last group. Keep the relative ordering within each group. Presentation changes
+must preserve permissions: hiding a column or removing a badge must not hide an
+otherwise available management action or grant a new one.
+
+### Configuration dialogs
+
+For sign-in providers, the table summarizes Enabled, Sign-in, Registration,
+and Approval with Yes/No values. Configure in the row action menu opens the
+switches in a dialog. Each switch has a clear label and a short explanation of
+what it changes, its dependencies, and its effect on existing accounts. Keep
+the old automatic-registration-closure sentence out of the table.
+
+The dialog states that changes save immediately. Save one field at a time,
+show failures in the dialog, and retain the server's values on failure. During
+a save, prevent conflicting changes and premature dismissal. Done closes the
+dialog; it is not a second save step.
+
+Turning Enabled off disables the dependent switches without changing their
+saved checked states. Re-enabling makes those settings available again,
+subject to the existing safeguards. Explain disabled controls visibly and on
+keyboard focus or hover so touch users can discover the reason too.
+
+Moving controls must preserve business rules. The final enabled provider with
+sign-in allowed cannot have Enabled or Sign-in turned off. Keep inherited
+registration behaviour, server-side enforcement, and refreshed safeguards after
+each change. The built-in E-mail provider has Configure, but no credential
+editor or Remove action. Editing another provider's credentials must not
+silently overwrite the flags managed by Configure. Implementation details live
+in [the account and login notes](../apps/server/web/docs/settings-account-login.md).
+
+### Review at small and large widths
+
+Check both phones and wide desktop screens, including 320px and a screen wider
+than 1440px. Verify aligned page gutters, readable type, compact rows, matched
+header/cell visibility, reachable actions, expanded content, and long names.
+Check empty, loading, and error states as well as populated tables. A layout
+must not look correct only with short sample names or one row.
+
 ## Patterns
 
 Each rule closed a real defect (spec § 4). A pattern without a reason is not
 admitted here.

 - **Line item**: `label` over `detail`, differing by weight AND colour, never
