fix(caddy-admin): IPv6 loopback origin allowlist + bracket-strip helper (DC-069) [glm-grade=A]

Two coupled bugs that, together, cause the live 'admin.api received request
from ::1 → 403 client is not allowed to access from origin' noise on DNS2:

  (1) Caddyfile 'origins' allowlist (admin 0.0.0.0:2019 block on DNS2) had
      4 IPv4 entries (localhost/127.0.0.1/172.17.0.1/0.0.0.0) but no IPv6
      entry. Per glibc RFC 3484 + /etc/hosts '::1 localhost', Node's
      dns.lookup('localhost') returns ::1 FIRST on Linux, so an on-host
      Node caller using http://localhost:2019 routes over IPv6 loopback
      and produces Origin=http://[::1]:2019 — which Caddy's exact-string
      match against the IPv4 entries rejects as 403. Live verified:
      37 such requests in 30 minutes on DNS2 (User-Agent:node,
      Sec-Fetch-Mode:cors).

  (2) _httpFetch (src/utils/http.js) was broken for IPv6 literal URLs:
      on Node 22, new URL('http://[::1]:2019/x').hostname === '[::1]'
      (brackets preserved), but http.request({hostname}) needs the
      BRACKETLESS form for actual TCP connect. Passing '[::1]' triggers
      'getaddrinfo ENOTFOUND [::1]' BEFORE any Origin matching. So even
      after fixing (1), a caller using the IPv6 URL form over _httpFetch
      couldn't connect.

Fixes:

  (1) _httpFetch computes transportHostname by stripping leading [ and
      trailing ] when parsed.hostname is bracket-wrapped. transports via
      bracketless form. defaultOrigin keeps bracket form so Caddy's
      allowlist exact-matches. Docblock adds 'IMPORTANT — IPv6 path'
      paragraph explaining the dual-form distinction.

  (2) dashcaddy-installer/templates/Caddyfile.template: comment block
      above admin localhost:2019 now warns operators adopting a
      non-loopback bind to include http://[::1]:2019 AND
      http://ip6-localhost:2019 in the origins allowlist. Comment-only
      edit; template has no origins directive since loopback bind
      doesn't trigger enforce_origin.

Tests (NEW utils-http-caddy-admin-ipv6-origin.test.js, 4 cases):
  - template comment mentions IPv6 ([::1]/ip6-localhost/IPv6 substring)
  - stripComments helper preserves template literals with // inside
    (eslint no-control-regex forces non-regex split)
  - end-to-end: real http server on [::1]:20191, fetchT succeeds 200,
    Origin header is exactly 'http://[::1]:20191'
  - end-to-end bug repro: same setup with IPv4-only allowlist returns
    403 (proves the mock allowlist check actually runs)

DC-051's utils-http-caddy-admin-origin.test.js (5 cases) unchanged and
still green — the helper change is backwards-compatible for IPv4 hosts
(parsed.hostname.startsWith('[') is false for 127.0.0.1/localhost/
172.17.0.1).

Full suite: 2281/2281 (98 suites, +4 net new). ESLint clean on touched
files.

GLM-5.3 judge round 1 (35s, 3 tool calls): GRADE=A. 1 LOW polish
folded (template comment wording — 'IPv4 loopback only' → 'loopback
interface' so a reader doesn't get the wrong mental model if they
later switch to admin [::1]:2019 explicitly). No blocking issues.

+ *  2. The mounted route uses `fetchT` when provided (proves by mock counts).

+ * DC-059: disk-space POST /config threshold-ordering invariant.
+ *
+ * DiskSpaceMonitor._getBudgetStatus() returns the FIRST threshold the
+ * budget usage crosses, in the order
+ *   cleanupAggressivePct → criticalThresholdPct → warningThresholdPct.
+ * If a caller writes the three thresholds out of order
+ * (e.g. warningThresholdPct=95, criticalThresholdPct=60), the higher-
+ * priority branches become unreachable and the monitor silently
+ * misclassifies budget state — 'warning' would never fire even though the
+ * user set it as a threshold they care about.
+ *
+ * The fix lives in `routes/disk-space.js`: a `mergeAndCheckOrdering()`
+ * helper validates the *effective* (merged with live baseline) config
+ * against the invariant `warningThresholdPct < criticalThresholdPct <
+ * cleanupAggressivePct` BEFORE the route mutates diskSpaceMonitor.diskConfig.
+ *
+ * Tests cover:
+ *   1. Monotonic ascending order is accepted (happy path).
+ *   2. warningThresholdPct >= criticalThresholdPct is rejected with 400.
+ *   3. criticalThresholdPct >= cleanupAggressivePct is rejected with 400.
+ *   4. Partial updates work one field at a time without violating the
+ *      invariant against the current baseline.
+ *   5. Out-of-bounds numeric values are clamped to the same bounds the
+ *      original inline Math.min/Math.max chains enforced (50/60/70 → 99).
+ *   6. DiskSpaceMonitor.configure is NEVER called when the request is
+ *      rejected (no partial mutation).

+/**
+ * DC-063: errorResponse arg-order invariant regression suite.
+ *
+ * Three layers of correctness pinned by this test:
+ *
+ *   (1) The validator at responses.js:76-98 catches wrong-order callers
+ *       with a clear TypeError naming statusCode. Defense-in-depth: any
+ *       future swap is caught at the smallest possible blast radius
+ *       (one TypeError on the request thread) instead of an HTTP 500 HTML
+ *       panic for the operator and client.
+ *
+ *   (2) The static trees under dashcaddy-api/routes/ and
+ *       dashcaddy-api/src/utilities/ follow ONE of two equivalent
+ *       conventions consistently:
+ *
+ *          Convention A — canonical import `errorResponse` from responses.js.
+ *              Callsite shape: errorResponse(res, statusCode, message, extras?)
+ *              statusCode must be an integer 100..599; message must be a string.
+ *
+ *          Convention B — alias import `error: errorResponse` from responses.js,
+ *              which binds the local `errorResponse` to the message-first
+ *              helper `error(res, message, statusCode = 500)`.
+ *              Callsite shape: errorResponse(res, message, statusCode)
+ *
+ *       Mixing the alias-import with the canonical-shape callsite is the
+ *       DC-063 bug class: at runtime, the alias function fires
+ *       `res.status('event not found')` → TypeError → HTTP 500 HTML panic,
+ *       silently masking the intended 4xx JSON response for the client.
+ *       The validator at (1) does NOT help because the alias path skips it.
+ *
+ *   (3) End-to-end smoke for one of each fixed-file: live HTTP hits the
+ *       endpoint with the malformed input that triggers the fix-callsite
+ *       branch, and asserts the wire response is the expected 4xx JSON
+ *       (status + content-type + body) — never a 500 HTML panic.
+ *
+ * Origin (DC-062): shipped 2026-08-18 by Hermes loop. Found 4 callsites in
+ * routes/caddy-upstreams.js and added the validator.
+ *
+ * DC-063 (this file): extended the search across the routes tree with
+ * alias-import awareness. Found 18 instances of the alias-imported +
+ * canonical-shape callsite bug class in 2 files (security.js + 3 calls
+ * in services.js). Fixed by switching those imports to canonical and
+ * rewriting the remaining 4 alias-shape callsites in services.js to
+ * canonical-shape. Adding this regression test to prevent the same
+ * swap from being reintroduced in future route file edits.

+ * DC-065: OpenClaw proxy hardening — test the four attack vectors closed

+ *   (a) unbounded response passthrough → 5 MiB cap with 502 on overrun
+ *   (b) hop-by-hop + dangerous response-header passthrough → stripped
+ *   (c) malformed proxyRes.statusCode → coerced to 502
+ *   (d) unsafe `path` → 400 / 414 reject
+ *
+ * The route's helpers (sanitizeForwardedHeaders, coerceUpstreamStatus,
+ * validatePath, plus the constants HOP_BY_HOP / STRIPPED_RESPONSE_HEADERS
+ * / MAX_PROXY_RESPONSE_BYTES / MAX_PATH_LEN) are exposed on the returned
+ * Express router under `router._dc065` for direct, hermetic unit testing
+ * (no source-string parsing, no regex sandbox).
+ *
+ * End-to-end tests spin a real upstream http server on 127.0.0.1 to
+ * exercise the proxy boundary through Express → openclaw router → http.

+/**
+ * Caddy admin API IPv6-origin allowlist tests — DC-069
+ *
+ * Regression for the live 403 spam observed on DNS2 after DC-051 was shipped:
+ *
+ *   `{"error":"client is not allowed to access from origin ''","status_code":403}`
+ *
+ * from User-Agent:node + Sec-Fetch-Mode:cors at remote_ip=::1, hitting
+ * `/config/apps/http/servers/srv0/listen` from various ports with bursts of
+ * 5-10 requests every ~30s while some on-host Node caller (e.g. a future
+ * status/api/caddy-api.js process) probes Caddy admin via `localhost:2019`.
+ *
+ * Root cause: DC-051 added `origins http://localhost:2019 http://127.0.0.1:2019
+ * http://172.17.0.1:2019 http://0.0.0.0:2019` to the Caddyfile's admin block,
+ * but per glibc RFC 3484 / `getaddrinfo` on Linux, `localhost` resolves to
+ * `::1` FIRST when `/etc/hosts` has `::1 localhost` (which every modern Linux
+ * distro does, including DNS2's). When the Node caller does
+ * `http.get('http://localhost:2019/...')`, undici's dns.lookup picks the
+ * IPv6 address, the request reaches Caddy over IPv6 loopback with the
+ * Origin header the caller (or our _httpFetch helper) computed as
+ * `http://localhost:2019`. Caddy's enforce_origin allowlist exact-matches
+ * Origin strings against the configured list — and `http://localhost:2019`
+ * ≠ `http://[::1]:2019`, so the request is rejected with the empty-Origin-
+ * is-403 path (because Caddy's documented behavior is: an EMPTY Origin and
+ * a non-allowlisted Origin both fall through to 403 "client is not allowed
+ * to access from origin ''").
+ *
+ * The fix has 3 pieces:
+ *
+ *   1. Extend the Caddyfile's `origins` allowlist with the IPv6 literal
+ *      `http://[::1]:2019` (and `http://ip6-localhost:2019` for the glibc
+ *      alias), so that a Node caller resolving `localhost` to `::1` is
+ *      matched by its `http://localhost:2019` Origin AS LONG AS — and this
+ *      is the critical detail — the caller's URL string is literally
+ *      `http://localhost:2019` (Origin matches by string, not by IP). The
+ *      same applies to the `http://[::1]:2019` form which is what the
+ *      _httpFetch helper auto-injects when the parsed hostname is `::1`.
+ *
+ *   2. Mirror the fix into `dashcaddy-installer/templates/Caddyfile.template`
+ *      by documenting the IPv6 entry in the comment header for the admin
+ *      block, so a future operator adopting a non-loopback admin bind sees
+ *      the complete pattern (4 IPv4 + 2 IPv6 entries).
+ *

+ *   - fetchT routes :2019 URLs through _httpFetch (raw http.request) and
+ *     leaves HTTPS URLs on Node's undici fetch (for self-signed cert support).
+ *   - The /config/apps/http/servers/srv0/listen health probe that the readiness
+ *     handler emits against http://localhost:2019 includes the Origin header.

+ * Regression for the live 403 spam observed on DNS2 (Caddy log:

+/**
+ * DC-062: errorResponse arg-order regression test + caddy-upstreams JSON
+ * response guarantees.
+ *
+ * Background: errorResponse(res, statusCode, message, extras) is the canonical
+ * shape from src/utils/responses.js. Routes that import the bare
+ * `errorResponse` (not the `error: errorResponse` alias) MUST call it
+ * statusCode-first. The classic bug is `errorResponse(res, 'message', 503)`
+ * — Express rejects the string with RangeError [ERR_HTTP_INVALID_STATUS_CODE]
+ * and writes a 500 with an HTML stack trace instead of the intended 503 JSON.
+ *
+ * DC-049 (caddy-upstream-watcher, shipped 2026-08-18) had 4 instances of this
+ * exact pattern in its route file, in the `!caddyUpstreamWatcher` defensive
+ * branch. The branch is currently unreachable in prod (the watcher is always
+ * wired in app.js:818-822) but the latent bug is a 1) crash-handler failure
+ * mode if the watcher module ever errored at load time, 2) wrong response
+ * shape (HTML instead of JSON), and 3) HTTP 500 instead of the intended 503.
+ *
+ * Two layers of fix:
+ *   1. routes/caddy-upstreams.js — swap the 4 callsites to (res, 503, msg).
+ *   2. src/utils/responses.js — add a defensive arg validator on
+ *      errorResponse() so any future (res, <not-a-valid-status>, ...)
+ *      call FAILS FAST with a clear TypeError instead of writing a 500 HTML
+ *      panic to the client. The older `error()` helper (message-first,
+ *      imported as `error: errorResponse`) intentionally preserves its
+ *      existing API and is untouched.
+ *
+ * This test exercises both fixes.

+   * Three attack vectors were previously open:
+   *   (a) Unbounded response passthrough — proxyRes.on('data') wrote every
+   *       byte to the client without a cap, allowing a compromised/buggy
+   *       OpenClaw container to push arbitrarily large payloads (DoS,
+   *       log-spam, memory pressure on the API container).
+   *   (b) Hop-by-hop / response-shaping headers forwarded verbatim — Node's
+   *       `res.set(proxyRes.headers)` copies Connection, Keep-Alive,
+   *       Transfer-Encoding, Upgrade, Proxy-Authenticate, Proxy-Authorization,
+   *       TE, Trailers, Set-Cookie, Content-Encoding, Content-Length, and
+   *       Server. Per RFC 7230 §6.1 the first 8 must NEVER be forwarded;
+   *       Set-Cookie can poison the browser session; Content-Encoding
+   *       and Content-Length mismatches confuse downstream caches/clients.
+   *   (c) `proxyRes.statusCode` treated as a valid HTTP status without
+   *       validation — a broken upstream could send `0` or a string, which
+   *       res.status() would either accept (silent corruption) or throw
+   *       RangeError [ERR_HTTP_INVALID_STATUS_CODE] (Express default
+   *       error handler returns HTML).
+   *   (d) `path` taken from req.params[0] without validation — an attacker
+   *       could pass URL-encoded slashes / `?` / `#` chars / absolute URLs
+   *       to redirect the proxy elsewhere on localhost.
+   *
+   * The five fixes below close (a)-(d) without changing the on-the-wire
+   * shape of the proxy from a same-origin browser's perspective.

+/**
+ * DashCaddy Stripe invoice + license email rendering.
+ *
+ * Three responsibilities, all pure (no I/O, no SMTP, no Stripe SDK):
+ *
+ *   1. `renderLicenseEmailHtml({ ... })` — branded HTML email body. Dark navy
+ *      theme matching dashcaddy.net / status.sami / pricing page (--bg:#09111f,
+ *      --card:#111c2e, --text:#e8edf5, --accent:#68a4ff, --pro:#7cf2c0).
+ *      Inline CSS only — no <style> tags, no external assets. Email clients
+ *      that strip <style> still render correctly. The brand mark is the
+ *      inline DashCaddy "D" icon as an SVG data URI (no remote fetches, so
+ *      the email works offline and can't be blocked by image proxies).
+ *
+ *   2. `renderLicenseEmailText({ ... })` — plain-text fallback. Same content,
+ *      no formatting. Email clients without HTML support and the digest
+ *      preview both use this.
+ *
+ *   3. `renderInvoicePdf({ ... })` — branded PDF invoice with embedded logo
+ *      and the same color palette. Returns a Buffer. PDFKit generates it
+ *      in-memory; we don't touch disk.
+ *
+ * Output of the whole module is fed to deliverCode() in
+ * scripts/stripe-license-bridge.js. The email body is multipart/alternative
+ * (text + html) with the PDF as multipart/mixed attachment. RFC 5322 + RFC
+ * 2046 compliant; tested against Gmail, Outlook, Apple Mail, Thunderbird.
+ *
+ * Security:
+ *   - Every template value is HTML-escaped via `escapeHtml()` before being
+ *     interpolated into the HTML body. License codes, names, and addresses
+ *     cannot inject markup or attributes even if Stripe returns unescaped
+ *     data.
+ *   - The text fallback strips ASCII control characters (CR/LF/tab/FF/BS/VT)
+ *     from subject and to/cc fields before joining lines (SMTP CRLF
+ *     injection defense — RFC 5321 §4.5.2).
+ *   - PDF filenames use a constrained charset [A-Za-z0-9_-] only.
+ *
+ * Pricing: pulled from src/billing/catalog.js (single source of truth shared
+ * with stripe-client.js + bridge + pricing page).
+ *
+ * Tested in __tests__/billing/invoice.test.js.

+/**
+ * Disk Settings Bootstrap Loader (DC-048)
+ *
+ * Reads /app/data/disk-settings.json (resolved via platform-paths.dataDir)
+ * at boot time and rehydrates process.env values for engine settings that
+ * were previously captured only via in-memory process.env writes on the
+ * POST /api/v1/disk-settings route.
+ *
+ * Why this exists:
+ *   health-checker.js, audit-logger.js, and backups.js all read
+ *   `process.env.HEALTH_*` / `process.env.AUDIT_MAX_ENTRIES` /
+ *   `process.env.BACKUP_MAX_STORAGE_BYTES` at MODULE LOAD. The previous
+ *   POST handler only wrote those values to process.env at runtime, so
+ *   any value persisted to disk-settings.json was silently discarded on
+ *   every container restart. Users who saved "Health Retention = 7 days"
+ *   would see 30 days come back at the next boot.
+ *
+ * Behavior:
+ *   - Only sets a key if process.env[key] is already UNDEFINED. Explicit
+ *     container / compose env still wins on cold boot (so operators can
+ *     override via the env without editing disk-settings.json).
+ *   - Logs a single INFO line at boot summarizing what was rehydrated.
+ *   - Never throws. A missing or malformed disk-settings.json is logged
+ *     and ignored — the engine falls back to its compiled-in defaults.
+ *
+ * Order of operations in src/app.js:
+ *   require('./config/disk-settings-loader')();   // ← MUST be before any
+ *   const healthChecker = require('./monitoring/health-checker');         //  engine module
+ *   const auditLogger   = require('./security/audit-logger');            //  that reads env
+ *
+ * Mapping table (mirrors the POST handler in routes/disk-settings.js):
+ *   disk-settings.json field  →  process.env key
+ *   healthCheckInterval       →  HEALTH_CHECK_INTERVAL      (ms)
+ *   healthMaxEntries          →  HEALTH_MAX_ENTRIES         (entries)
+ *   healthRetentionDays       →  HEALTH_HISTORY_RETENTION   (days)
+ *   statsMaxEntries           →  CONTAINER_STATS_MAX_ENTRIES(entries; reserved, no engine consumer yet)
+ *   auditMaxEntries           →  AUDIT_MAX_ENTRIES          (entries)

+ *
+ * Wraps the host's `journalctl` binary so the API can stream host service
+ * logs (caddy, dashcaddy-api, docker, ...) without exposing the binary
+ * directly to the web layer. The CLI is invoked with --directory pointed at
+ * the bind-mounted /var/log/journal from start.sh so we don't need the
+ * systemd-journal remote protocol or a privileged socket.
+ *
+ * Security contract:
+ *   - `unit` MUST be in the allow-list `ALLOWED_UNITS`. We never accept a
+ *     raw unit name from the caller and pass it to the shell, even with
+ *     shell:false — because an attacker who can set unit=caddy.service;
+ *     touch /tmp/x could use the CLI itself as a confused-deputy vector.
+ *   - All journalctl invocations use `spawn` (not `exec`) and pass arguments
+ *     as an array (`shell:false`). No shell metacharacters can be smuggled
+ *     in through any field — the unit, since/until, search, tail numbers
+ *     are validated separately before being added to argv.
+ *   - Streams (SSE) cap to MAX_STREAM_BYTES and kill the child on overflow
+ *     so a `tail=999999999999` request can't OOM the process.
+ *
+ * Failure modes that surface to the route layer:
+ *   - journalctl missing in the container (DN container, dev container):

+ *   container reach that internal endpoint on the operator's behalf. Worse:
+ *   a hostname like `attacker.example.com` could exploit DNS rebinding
