+
+### Patch Changes
+
+- Six reviewed contributor PRs (all adversarially reviewed and fixed before merge):
+  - **Markdown sanitizer hardened against mutation-XSS (#126).** The denylist `_sanitizeHtml` is replaced with vendored DOMPurify 3.4.8 (authentic, byte-matched to the official dist) wired via a new `sanitize-html.js` allowlist, with a fail-closed escape fallback. The curated allowlist is genuinely enforced (no `USE_PROFILES` override) so non-markdown tags and svg/math/style/script/event-handler/`javascript:` vectors are stripped while legitimate markdown survives.
+  - **Hook-event secret now required unconditionally (#127).** The `/api/hook-event` + `/api/status-telemetry` localhost bypass requires the per-instance hook secret whether or not a managed tunnel is running, closing the own-loopback-reverse-proxy gap. A self-heal refreshes pre-secret hook configs in existing cases on spawn so password-protected installs don't silently 401 their hooks. No-password loopback installs are unaffected.
+  - **`codeman doctor` dependency checker (#125).** New `doctor`/`check-deps` command probes Node, the agent CLIs, tmux, and document converters per environment (linux/darwin/win32/wsl), with grouped or `--json` output and a non-zero exit when a required tool is missing. Requires Node 22+, reports `pdftoppm` (used for PDF/Office thumbnails), and validates `--category`.
+  - **macOS Option / physical-key session shortcuts (#129).** Tab switching matches physical key codes (`e.code`) so Option+1–9 works on macOS layouts that remap Option, plus Option/Alt+`[`/`]` for previous/next session — without leaking escape sequences into the focused terminal.
+  - **Desktop session tabs auto-wrap to a second row on overflow (#128)** instead of horizontal scrolling (off when the manual two-row layout is pinned; mobile/tablet unchanged), re-evaluated on window resize.
+  - **CJK input textarea hidden on the welcome screen (#123)** so it no longer floats over the welcome overlay, and re-shown on session entry; vertical centering fixed.

+ *
+ * Security (COD-56): the previous sanitizer was a hand-rolled DENYLIST — it removed a fixed
+ * set of tags (script/iframe/object/embed/form/base/meta/link/style), stripped on* attrs and a
+ * few dangerous URL schemes, then re-serialized. Denylists are mXSS-prone: they did not strip
+ * `svg`/`math` (which carry their own foreign-namespace parsing rules and can smuggle script via
+ * namespace confusion), did not strip `style` attributes (CSS `expression()`/`url(javascript:)`
+ * on legacy engines), and had no positive allowlist, so any tag/attribute not explicitly named
+ * survived. `marked` runs with raw-HTML passthrough, so crafted HTML echoed by an agent flows
+ * straight into this function.
+ *
+ * This module replaces that with DOMPurify (Cure53), an allowlist sanitizer that is the
+ * industry standard for mXSS defense. It is configured to allow exactly the tag/attribute set
+ * that markdown rendering legitimately produces (headings, lists, code, blockquotes, links,
+ * tables, images with safe src) and to FORBID `style`/`svg`/`math` plus all event handlers and
+ * dangerous URL schemes.
+ *
+ * Cross-environment: in the browser this file runs as a classic <script> after
+ * vendor/dompurify.min.js and wires `window.sanitizeMarkdownHtml`. The factory is also exported

+/**
+ * COD-56 — markdown HTML sanitizer (mXSS hardening).
+ *
+ * The response viewer / attachment preview render agent- and transcript-derived markdown to
+ * HTML via `marked` (raw-HTML passthrough) and assign the result with innerHTML. The HTML must
+ * be sanitized first. The original sanitizer (`_sanitizeHtml` in app.js) was a hand-rolled
+ * DENYLIST and is mXSS-prone — it never stripped `svg`/`math`/`style`, so foreign-namespace and
+ * CSS vectors survived.
+ *
+ * This suite drives the EXACT shipping artifacts:
+ *   - src/web/public/vendor/dompurify.min.js   (the vendored sanitizer)
+ *   - src/web/public/sanitize-html.js          (our allowlist config wired to DOMPurify)
+ *
+ * It runs in the DEFAULT node environment (it deliberately does NOT declare a per-file jsdom
+ * environment) and constructs a jsdom window here, then binds the vendored DOMPurify to it. A
+ * per-file jsdom environment externalizes node:fs/node:path under vite, which made this suite fail
+ * to load when
+ * run in isolation (it only survived the full CI run because an earlier node-env test happened to
+ * pre-cache node:fs). Building the window in-test keeps fs/path native and the suite order-robust.
+ *
+ * It feeds a corpus of mXSS payloads (svg/math/style/namespace-confusion/event-handler) and
+ * asserts the output carries NO script-executing constructs, that the curated allowlist is
+ * actually enforced (non-markdown tags dropped), and that legitimate markdown-rendered HTML
+ * survives unchanged. A faithful re-implementation of the OLD denylist is included and asserted to
+ * LET payloads through — the gap this fix closes.
+ *
+ * No port / server needed.
