M-1 TokenExtract: exact-name cookie parse (new pure cookieValue helper) —
a substring find("session=") could be shadowed by a sibling xsession=,
defeating __Host-/__Secure- prefix guarantees.
M-2 AuthInterceptor: gate setup-mode pseudo-admin on a loopback bind and log
the grant; document that IAuthBackend::hasActiveUsers() must fail closed.
M-3 ws/Hub: empty propertyIds now means NO access for non-admins (was "all") —
a non-admin whose scope set failed to populate no longer gets every
property's notifications. Admins still get all via role.
M-4 new util/OriginCheck.hpp (originHostname/sameOrigin/originAllowed) +
Hub doc: WSController must validate Origin at the handshake (CSWSH).
M-6 RedactedFieldRepository: ctor throws on an unknown redaction field name
(a typo would silently redact nothing, leaving credentials in history).
M-7 RateLimiter: ctor validates capacity (finite >=1) / refillRate (finite >0),
throws std::invalid_argument — zero/negative/NaN silently disabled it.
M-8 TokenExtract: document that clientIpTrusted's "unknown"/"invalid" sentinels
collapse to one shared rate-limit bucket off-proxy.
M-9 new util/SessionCookie.hpp: safe-by-default Set-Cookie builder
(HttpOnly+Secure+SameSite=Strict+Path=/), rejects control chars / ';'.
M-10 AuthInterceptor: Origin/Referer-vs-Host check on session mutations
(defence in depth atop X-Requested-With); cert path documented as
non-browser / not CSRF-gated.
M-11 AuthInterceptor: optional injected RateLimiter throttles invalid-token
attempts per client IP → 429.
M-12 AuthInterceptor: sanitize request method/path (strip control chars, cap
length) before logging — closes log-line forging (CWE-117).
(M-5 — temporal non-atomic save — was already resolved by the H-4 fix.)
Tests: new test_token_extract / test_rate_limiter / test_origin_check /
test_session_cookie; extended test_redacted_field_repository. All 19 ctest
targets pass. README + header docs updated.
