PDF uploads are stored as markdown wrappers with pdf_source or pdf_form_source markers so the editor can preserve extracted text, form fields, and annotations. The library exposed that internal wrapper: auto-created PDF documents used the hashed storage filename as the title, and row/facet language reported markdown instead of pdf.
Derive chat-upload PDF titles from the original upload name, derive document-library display language from the PDF source marker for rows, filters, and facets, and keep markdown wrappers excluded from the markdown facet when they represent PDFs.
The expanded library card already renders PDF-backed documents through /api/document/{id}/render-pdf. Allow only that inline PDF preview endpoint to be framed by same-origin app pages while leaving normal routes on X-Frame-Options: DENY and frame-ancestors none.
Also tighten the existing PDF marker regression assertion so it matches the actual historical corruption signature instead of contradicting the preserved [Page 1 text]: marker.
Fixes#2468
AuthMiddleware is the outermost middleware, so a credential-less CORS preflight
(OPTIONS + Access-Control-Request-Method) was rejected with 401 before
CORSMiddleware could answer it. That blocks every cross-origin browser/WebView
client: the preflight fails, so the real request is never sent.
Let a genuine preflight through at the top of AuthMiddleware.dispatch via a pure,
unit-tested predicate (core.middleware.is_cors_preflight). Precise -- only
OPTIONS carrying Access-Control-Request-Method; a credentialed request is never
matched -- and no data access.

* fix(security): add HSTS and Permissions-Policy headers to SecurityHeadersMiddleware
Strict-Transport-Security is sent only when the connection is HTTPS
(detected via request.url.scheme or X-Forwarded-Proto: https), so
plain-HTTP dev deployments behind a reverse proxy are unaffected.
Permissions-Policy disables camera, microphone, and geolocation APIs
unconditionally — Odysseus does not use them, and this prevents a
successful XSS from requesting browser-native sensor access.

* fix(security): scope Permissions-Policy microphone directive to same-origin
Reviewers on PR #3081 (alteixeira20, NubsCarson) flagged that
microphone=() blocks mic access for same-origin (self) too, breaking
Odysseus's own voice/STT flow (getUserMedia({audio: true}) in
static/js/voiceRecorder.js). Scope it to microphone=(self) so
third-party origins stay locked out while the app's own UI keeps mic
access; camera and geolocation remain fully disabled as unused.
Adds focused middleware tests covering HSTS scoping (HTTPS direct,
X-Forwarded-Proto, absent on plain HTTP) and the Permissions-Policy
same-origin microphone contract.

Hardens issues found in a security review of the current tree (separate from
the cookbook SSH PR):
- Email thread rendering (static/js/emailLibrary.js): the flat read path runs
inbound HTML through the allowlist sanitizer, but the two threaded paths
(_renderTurnsAsBubbles / _renderTurnsFromServer — the default view) injected
server-parsed `body_html` raw into the DOM. A crafted inbound email could
inject arbitrary markup (phishing/form/credential-capture/tracking; full XSS
if a deployment relaxes the script CSP). Now sanitized on all paths.
- Attachment extraction (routes/email_routes.py, routes/email_helpers.py): the
on-disk extraction dir was `ATTACHMENTS_DIR / f"{folder}_{uid}"` with
user-controlled folder/uid and no containment, so a folder like `../../tmp`
could escape ATTACHMENTS_DIR. New attachment_extract_dir() flattens both to a
single safe segment and asserts containment.
- Diagnostics routes (routes/diagnostics_routes.py): /api/db/stats,
/api/rag/stats, /api/test/youtube, /api/test-research relied only on the
global session check (any logged-in user). Now require_admin-gated.
- Defense-in-depth HTML escaping: session HTML export escapes the session name
(routes/session_routes.py); the MCP OAuth page escapes the reflected Host
header / server_id (routes/mcp_routes.py).
- Internal-tool token now compared with secrets.compare_digest (constant time)
in core/middleware.py and app.py.
Adds regression tests in tests/test_security_regressions.py.
