Add scripts/removeAdvancedMessaging.js + extract shared bulk lib

New scripts/removeAdvancedMessaging.js reads a Users Export CSV
and bulk-removes the Advanced Messaging and Advanced Space Meetings
licenses from every listed user (with optional add of a Basic
Messaging license, though in most Webex orgs Basic Messaging is a
derived entitlement and no explicit add is required).

Detection is authoritative like the reclaim script: the assignee
rosters of the two Advanced licenses are fetched once up-front,
unioned by email, and the CSV is cross-referenced. PersonIds come
straight off the roster (no per-user /people lookup). Only the
remove ops the user actually still needs are emitted — the PATCH
body is trimmed per user based on which licenses they hold.

Dry-run enumerates every org license whose name matches
/message|advanced|space|basic/i so the operator can discover the
three ids without prior knowledge. --advanced-messaging-license-id,
--advanced-space-meetings-license-id, and --basic-messaging-license-id
also read WEBEX_ADV_MSG_LICENSE_ID / WEBEX_ADV_SPACE_MTG_LICENSE_ID
/ WEBEX_BASIC_MSG_LICENSE_ID from .env if set.

Also extracted the CSV parsing, format detection, pool/retry
helpers, and Webex license helpers from reclaimWebexHosts.js into
a shared scripts/lib/webexBulk.js module. reclaimWebexHosts.js now
imports from it — no behavior change (verified against both CSV
formats: 1028 candidates on the Meetings Inactive Users report,
665 on the Users Export report). Net -106 lines from the reclaim
script.

.gitignore updates:
  - whitelist scripts/lib/ and the new removeAdvancedMessaging.js
    file so they get tracked
  - exclude reclaim-*.csv and remove-*.csv (per-user report CSVs
    generated by --report contain PII and must never be committed)

+#
+# WHY NO `apk add`: corporate DCs commonly TLS-intercept HTTPS. Alpine's
+# apk fetch of dl-cdn.alpinelinux.org fails inside the container when
+# the CA chain includes a proxy cert the container doesn't trust. We
+# avoid the problem entirely by not fetching anything from Alpine at
+# build time. Signal handling (SIGTERM / SIGINT / SIGUSR2) is done in
+# index.js so we don't need tini/dumb-init.
+#
+# WHY NO RUNTIME `npm install`: the bundle.sh workflow builds this
+# image ONCE outside the DC (where npm registry access works), saves
+# it as a tarball, and ships the tarball. The DC only runs
+# `docker load` + `docker compose up -d` — zero network calls beyond
+# the initial docker load.
+#
+# WHERE node_modules LIVES (subtle but critical):
+#   /workspace/node_modules   ← NOT under dect-relay-agent/
+#
+# The agent imports `../integrations/cisco-dect/client.js`, which
+# in turn does `import axios from 'axios'`. Node's ESM resolver
+# walks UP from the IMPORTING file (client.js) looking for
+# node_modules — it does NOT search siblings. So if node_modules
+# lived at /workspace/dect-relay-agent/node_modules, then
+# client.js (at /workspace/integrations/cisco-dect/client.js) would

+# Placing node_modules one level higher fixes it: both the agent
+# AND the shared integrations resolve axios via /workspace/node_modules.

+# DECT Relay Agent
+
+Bridges the CollabSupport bot (public cloud) to Cisco DBS-210 DECT base stations on the private `10.0.0.0/8` corporate network.
+
+## Why it exists
+
+The bot process runs in the public cloud and can't reach `10.x`. This agent runs inside the data center, dials outbound over WSS to the bot, and executes any DECT command (collect status, reboot, factory-reset, etc.) the bot pushes to it.
+
+Only one agent is expected to run at a time. If a second agent connects, the bot assumes it's a legitimate restart, closes the old socket, and adopts the new one.
+
+## Prerequisites
+
+- Node.js ≥ 20
+- Route from the agent host to `10.0.0.0/8` on TCP 443
+- Route from the agent host to the bot's public HTTPS endpoint
+- The DECT serviceability password (Control Hub → Calling → Features → DECT Networks → Manage → Manage DECT serviceability password)
+
+## Deploy paths
+
+There are two ways to run this. Pick one based on where you're deploying.
+
+### 1. Docker container in the data center (recommended for production)
+
+The DC host makes **zero network calls** during install — the image is built on your dev machine, saved as a tarball, and shipped inside a self-contained ZIP. This sidesteps the TLS-interception problem that breaks `apk add` and `npm install` inside containers on corporate networks.
+
+**On your dev machine (with Docker Desktop / internet access):**
+
+```bash
+# From the repo root — script is self-locating:
+./dect-relay-agent/bundle.sh
+# → writes dect-relay-agent-bundle-<YYYYMMDD-HHMMSS>.zip (~40-60MB)
+```
+
+Optional overrides:
+
+```bash
+./dect-relay-agent/bundle.sh --tag 0.2.0            # override version
+./dect-relay-agent/bundle.sh --platform linux/arm64 # if the DC is ARM
+```
+
+**On the DC host** (once you've transferred the ZIP):
+
+```bash
+unzip dect-relay-agent-bundle-*.zip
+cd dect-relay-agent-bundle-*
+cp .env.example .env
+$EDITOR .env                      # set BOT_URL + AGENT_TOKEN + ADMIN_PASSWORD
+./install.sh
+```
+
+`install.sh` is idempotent — re-run it after transferring a newer bundle to upgrade. It:
+1. `docker load`s the image tarball
+2. Pins the loaded tag into `.env` (so compose never falls back to a stale local image)
+3. Validates required env values are set (not still placeholder strings)
+4. `docker compose up -d`
+5. Tails the last 40 log lines so you can see the "Connected — sending hello" message
+
+**What the runtime container looks like:**
+
+- Non-root `node` user (uid 1000)
+- Read-only root filesystem, 16MB tmpfs at `/tmp`
+- All Linux capabilities dropped, `no-new-privileges`
+- Host networking (so it can reach `10.x/8` without userland proxy translation)
+- No listening ports — outbound-only WSS to the bot
+- Log rotation: 10MB × 5 files max
+
+### 2. Direct node process (dev + local iteration)
+
+```bash
+cd dect-relay-agent
+npm install
+```
+
+`ws`, `axios`, and `dotenv` are the only runtime dependencies. The agent imports the shared `integrations/cisco-dect/` modules from the parent repo via relative paths, so the parent workspace must be present on disk.
+
+## Configure
+
+```bash
+cp .env.example .env
+$EDITOR .env
+```
+
+Required values:
+
+| Var | Meaning |
+|---|---|
+| `DECT_RELAY_BOT_URL` | Full WSS URL to the bot's DECT relay endpoint (`wss://your-bot-host/dect-relay/ws`) |
+| `DECT_RELAY_AGENT_TOKEN` | Shared bearer token — MUST match the bot's `DECT_RELAY_AGENT_TOKEN` exactly |
+| `DECT_ADMIN_USER` | Usually `admin` |
+| `DECT_ADMIN_PASSWORD` | Fleet-wide serviceability password |
+
+Generate a fresh token: `openssl rand -hex 32`. Rotate on both sides at once — the bot compares tokens with `timingSafeEqual` and will reject any drift with a 401 on the WSS upgrade.
+
+## Run
+
+```bash
+npm start
+```
+
+You should see:
+
+```
+[startup] dect-relay-agent v0.1.0 — hostname=..., bot=wss://...
+[connect] Dialing wss://.../dect-relay/ws
+[connect] Connected — sending hello
+```
+
+And on the bot side:
+
+```
+[dect:relay-hub] Agent connected from ...
+[dect:relay-hub] Agent hello: version=0.1.0 host=... caps=collect,reboot,...
+```
+
+## Wire protocol
+
+All frames are JSON, one per WebSocket message.
+
+**Agent → Bot on connect:**
+```json
+{ "type": "hello",
+  "agentVersion": "0.1.0",
+  "hostname": "dc-dect-relay-01",
+  "capabilities": ["collect","reboot","force-reboot","reboot-chain",
+                   "force-reboot-chain","factory-reset","reconfigure-tree"] }
+```
+
+**Bot → Agent (command):**
+```json
+{ "id": "cmd_<uuid>", "type": "collect", "baseIp": "10.4.11.87" }
+{ "id": "cmd_<uuid>", "type": "reboot",  "baseIp": "10.4.11.87" }
+```
+
+**Agent → Bot (reply):**
+```json
+{ "id": "cmd_<uuid>", "ok": true, "elapsedMs": 812,
+  "result": { "parsed": { ... }, "verdict": { "healthy": true, ... } } }
+
+{ "id": "cmd_<uuid>", "ok": false,
+  "error": { "code": "DIGEST_401", "message": "Base rejected credentials" } }
+```
+
+**Heartbeat (both directions, every 30s):**
+```json
+{ "type": "ping", "at": 1720000000000 }
+{ "type": "pong", "at": 1720000000000 }
+```
+
+The bot terminates the socket if no `pong` arrives within 90s; the agent auto-reconnects with exponential backoff (1s / 2s / 4s / … capped at 30s + 0-1000ms jitter).
+
+## Safety guarantees
+
+- DECT admin credentials NEVER leave this agent. The bot only knows the WSS bearer token.
+- All mutating actions (reboot, factory-reset, reconfigure-tree) are only executed when the bot explicitly issues the corresponding command frame. The agent has no autonomous logic.
+- The agent enforces no policy — the bot decides who can reboot what. See the bot's audit log for the full record of actions taken (`igmp:audit` style scopes in daily log files).
+- The agent quarantines mutating actions from probes via the exact same safety model as the CLI tool (`integrations/cisco-dect/probes.js` — GET-triggered actions are only reachable via explicit `trigger*` helpers, never via a generic path fetcher).

+| `docker-compose.yml` | DC-side runtime shape (read-only rootfs, host net, capability drop, log rotation). |
+| `bundle.sh` | Dev-machine packager: `docker build` → `docker save` → `zip`. Runs on your machine. |
+| `install.sh` | DC-host installer: `docker load` → validate `.env` → `docker compose up -d`. Ships inside the bundle. |
+
+**Important**: the `Dockerfile` is designed to be built from the **repo root**, not from this folder, because it needs `../integrations/cisco-dect/*` and `../utils/httpDigestAuth.js` in the build context. `bundle.sh` does this correctly:
+
+```bash
+docker build -f dect-relay-agent/Dockerfile -t ... .   # note the trailing `.`
+```
+
+Building with `docker build dect-relay-agent/` will fail (missing shared modules) — always use `bundle.sh`, or invoke `docker build` from the repo root with `-f dect-relay-agent/Dockerfile`.
+
+## Troubleshooting
+
+**`WARNING: fetching … TLS: server certificate not trusted` during build**
+You're building inside a TLS-intercepting corporate network. Don't — build on your dev machine and ship the tarball via `bundle.sh`. That's the whole point of this workflow.
+
+**`docker: permission denied while trying to connect to the Docker daemon socket`**
+The user running `install.sh` needs to be in the `docker` group. Either `sudo usermod -aG docker $USER` (log out/in after) or `sudo ./install.sh`.
+
+**Agent connects then immediately disconnects with 401**
+Bearer token mismatch. `DECT_RELAY_AGENT_TOKEN` on the bot side must match the agent's `.env` exactly. Rotate both together.
+
+**Agent connects but every `collect` returns `DIGEST_401`**
+DBS-210 admin password is wrong. Verify in Control Hub → Calling → Features → DECT Networks → Manage → Manage DECT serviceability password, update `DECT_ADMIN_PASSWORD` in `.env`, then `docker compose restart dect-relay-agent`.

+To install on this data-center host:
+
+  1. cp .env.example .env
+  2. Edit .env — set:
+       - DECT_RELAY_BOT_URL          (wss:// URL to the bot)
+       - DECT_RELAY_AGENT_TOKEN      (shared bearer, same as bot's env)
+       - DECT_ADMIN_PASSWORD         (DECT serviceability password)
+  3. ./install.sh
+  4. Watch it come up:  docker compose logs -f dect-relay-agent
+
+Files in this bundle:
+
+  image.tar.gz         Prebuilt Docker image (gzipped, ~40MB)
+  docker-compose.yml   Compose file — read-only rootfs, host network,
+                       log rotation. Loaded by install.sh.
+  .env.example         Config template.
+  install.sh           Runs 'docker load' then 'docker compose up -d'.
+                       Safe to re-run for upgrades.
+  AGENT-README.md      Full agent docs — wire protocol, safety model,
+                       run instructions.
+  README.txt           This file.
+
+No internet access required after the image is loaded. The container
+runs with a read-only root filesystem, drops all Linux capabilities,
+and uses the 'node' non-root user.
+
+Upgrading:
+  Unzip the new bundle in a new folder, or overwrite this one, and
+  re-run ./install.sh. install.sh pins the new image tag into .env

+// station's local admin web UI. This is a SPIKE — not wired into the
+// bot. The whole cisco-dect/ folder exists so we can reverse-engineer
+// what the DBS-210 exposes (reboot, PRT pull, syslog, config export)
+// against one lab base before productionizing behind a store-side
+// relay.
+//
+// What the DBS-210 UI actually is (confirmed from a HAR capture of a
+// real login against 192.168.1.164):
+//   - HTTPS on 443 with a self-signed cert → rejectUnauthorized:false.
+//   - Real entry page is `/main.html`, NOT `/` or `/admin/index.htm`.
+//     Root returns 404 or gets redirected; probes should target
+//     /main.html first for reachability + auth sanity.
+//   - HTTP DIGEST authentication (MD5, qop=auth), NOT Basic. First
+//     request returns 401 with:
+//       WWW-Authenticate: Digest realm="", nonce="...", algorithm="MD5", qop="auth"
+//     We handle this via an axios response interceptor: any 401 with
+//     a Digest challenge triggers a single retry with the correct
+//     Authorization header computed by utils/httpDigestAuth.js.
+//   - Response sets `Clear-Site-Data: "cookies"` on every reply, so we
+//     CAN'T lean on a session cookie — the Digest header goes on every
+//     single request. That's why we don't cache the nonce here; each
+//     request does its own challenge/response round-trip. Slower per
+//     call (2× RTT), but tiny wall-clock hit on LAN and it means we
+//     never carry stale nonces across a reboot.
+//   - NOT a REST/JSON API. Pages return HTML/CSS/JS/PNG bytes, no JSON.
+//     Callers get raw strings and decide how to parse.
+//
+// Safety notes for the spike:
+//   - No retries beyond the single Digest handshake. Timeouts + real
+//     errors surface directly so we can iterate on the endpoint list.
+//   - No refresh of any kind. Reboot / factory-reset are one-shot,

+ * Reclaim Webex Meetings host licenses from long-inactive users.
+ *
+ * Accepts either of two Control Hub exports:
+ *
+ *   1. "Meetings Inactive Users" (Analyzer → Meetings → Inactive Users)
+ *      Columns include EMAIL, IS_HOST, DAYS_SINCE_LAST_ACTIVE.
+ *      Candidate rule: IS_HOST=Y AND DAYS_SINCE_LAST_ACTIVE > --min-days.
+ *
+ *   2. "Users Export" (Users → Manage users → Export)
+ *      Columns include "User ID/Email (Required)", "User Status",
+ *      "Days since Last Service Accessed", one TRUE/FALSE column per
+ *      license (e.g. "aeo2go.webex.com - WebEx Meetings Free [SubXXX]").
+ *      Candidate rule: User Status ∈ {Inactive, Verified}.
+ *        - "Inactive" = active user that Webex has flagged idle
+ *        - "Verified" = never signed in
+ *      "Days since Last Service Accessed" is NOT used for this format
+ *      (a Verified user has never logged in, so days is blank), and
+ *      --min-days is therefore ignored.
+ *
+ * Format is auto-detected from the header. There's no host flag in
+ * format #2, but we don't need one: detection of "currently holds the
+ * host license" is authoritative, done by fetching the host license's
+ * assignee roster once up-front and cross-referencing the CSV emails.
+ * Anyone in the CSV who isn't currently a holder is silently skipped,
+ * and the personId comes straight off the assignee record (no per-user
+ * /people search needed).
+ *
+ * The mutation is one PATCH `/v1/licenses/users` per user:
+ *   1. remove the configured host license on the target site, and
+ *   2. atomically add either a specific "free tier" license, or an
+ *      attendee-only siteUrl on the site (accountType=attendee).
+ * Users are never briefly license-less.
+ *
+ * DRY-RUN by default. Nothing mutates without `--execute`. In dry-run,
+ * the script lists every license on the site so you can pick the
+ * `--free-license-id` (or decide to use `--free-attendee` instead).
+ *
+ * Usage:
+ *   node scripts/reclaimWebexHosts.js \
+ *     --csv "/path/to/<report>.csv" \
+ *     [--site aeo2go.webex.com] \
+ *     [--min-days 120] \
+ *     [--host-license-id <id>] \
+ *     [--free-license-id <id> | --free-attendee] \
+ *     [--concurrency 5] \
+ *     [--limit N] [--offset N] \
+ *     [--report reclaim-report.csv] \
+ *     [--execute]
+ *
+ * Environment defaults (read from .env):
+ *   WEBEX_HOST_SITE_URL     → --site (default aeo2go.webex.com)
+ *   WEBEX_HOST_LICENSE_ID   → --host-license-id
+ *   WEBEX_FREE_LICENSE_ID   → --free-license-id (optional)
+ *
+ * Required Webex service-app scopes:
+ *   spark-admin:licenses_read

+/**
+ * Bulk-remove Advanced Messaging + Advanced Space Meetings licenses.
+ *
+ * Reads a Control Hub "Users Export" CSV (Users → Manage users →
+ * Export). For every row that currently has either "Advanced Messaging
+ * [SubXXX]" = TRUE or "Advanced Space Meetings [SubXXX]" = TRUE, we
+ * PATCH `/v1/licenses/users` to atomically:
+ *   1. remove the Advanced Messaging license (if user has it), and
+ *   2. remove the Advanced Space Meetings license (if user has it), and
+ *   3. optionally add a Basic Messaging license if `--basic-messaging-
+ *      license-id` is provided. Note: in most Webex orgs, "Basic
+ *      Messaging" is a derived entitlement that's on automatically for
+ *      any user with a base license — you probably do NOT need to add
+ *      it explicitly. Removing the Advanced overlay leaves the user
+ *      with the basic tier. Use dry-run to see what licenses your org
+ *      actually has (the enumeration below filters on names matching
+ *      /message|advanced|space|basic/i).
+ *
+ * Detection is authoritative: we fetch the assignee rosters of both
+ * Advanced licenses once up-front (paginated) and cross-reference the
+ * CSV emails. Anyone in the CSV who no longer holds either license is
+ * silently skipped, and personIds come straight off the assignee
+ * records — no per-user /people lookup.
+ *
+ * DRY-RUN by default. Nothing mutates without `--execute`. In dry-run
+ * we enumerate org licenses whose names look messaging-relevant so you
+ * can pick the right IDs.
+ *
+ * Usage:
+ *   node scripts/removeAdvancedMessaging.js \
+ *     --csv "/path/to/AdvanceMessaging.csv" \
+ *     [--advanced-messaging-license-id <id>] \
+ *     [--advanced-space-meetings-license-id <id>] \
+ *     [--basic-messaging-license-id <id>] \
+ *     [--concurrency 5] \
+ *     [--limit N] [--offset N] \
+ *     [--report remove-advmsg-report.csv] \
+ *     [--execute]
+ *
+ * Environment defaults (read from .env):
+ *   WEBEX_ADV_MSG_LICENSE_ID          → --advanced-messaging-license-id
+ *   WEBEX_ADV_SPACE_MTG_LICENSE_ID    → --advanced-space-meetings-license-id

+//
+// Bot-side of the DECT relay: a WebSocket server that accepts ONE
+// long-lived connection from a data-center-resident relay agent, plus
+// a promise-based RPC API for the rest of the bot to call ("collect
+// this base's status", "reboot this base"). The agent — which lives
+// in `dect-relay-agent/` in this repo — makes the actual HTTPS Digest
+// calls to DBS-210 base stations on the private 10.x network.
+//
+// Why a WebSocket at all: the bot runs in the public cloud and can't
+// reach 10.x. The agent runs in the DC and can, but the DC can't
+// accept unsolicited inbound connections. WSS solves both sides: the
+// agent dials outbound to the bot (traversing NAT / proxy just like
+// any HTTPS request), and once the socket is up the bot can push
+// commands whenever it wants.
+//
+// Only ONE agent is expected to connect. If a second agent dials in,
+// we assume it's a legitimate restart (agent redeployed, network
+// blip, etc.), close the old socket, and replace it with the new one.
+// This is safe because the RPC pending-map is drained + rejected on
+// disconnect — any in-flight command reports back "relay disconnected"
+// rather than silently hanging.
+//
+// Auth is a static bearer token shared between bot .env and agent
+// .env. That's fine for a single trusted agent — WSS gives us
+// transport-level confidentiality, and rotating the token is a
+// two-line env change. If we ever need multiple agents we'd swap
+// this for per-agent tokens plus an agent-id → base-list registry.

+// HTTP Digest Authentication (RFC 7616, and the older RFC 2617 flavour
+// that most embedded devices still speak). Pure, dependency-free — no
+// network calls, no state. Feed it the parsed WWW-Authenticate params
+// plus the credentials and it hands back the `Authorization: Digest ...`
+// header value.
+//
+// Why we need this: axios' built-in `auth: {username, password}` only
+// speaks Basic. The Cisco DBS-210 DECT base station's admin UI (and
+// most Cisco small-business voice devices, they're all cousins of the
+// Sipura SPA family) rejects Basic and challenges with
+//   WWW-Authenticate: Digest realm="", nonce="...", algorithm="MD5", qop="auth"
+// so every request needs a fresh Digest hash. The DBS-210 also sets
+// `Clear-Site-Data: "cookies"` on every response, so we can't fall
+// back on a session cookie either — the Digest header goes on every
+// single call.
+//
+// Cisco quirk we handle explicitly: the realm can be an EMPTY string.
+// The Digest spec allows this, but some libraries silently drop empty
+// realms which corrupts HA1. We preserve `realm` exactly as sent.
